Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a communication system in which a host device and a plurality of terminal devices are connected via an information communication network, and the other party can be accessed from either the host device or the terminal device using, for example, a telephone number.EndIt relates to end devices.
[0002]
[Prior art]
  2. Description of the Related Art Conventionally, there is a communication system in which a host device and a plurality of terminal devices are connected via an information communication network, and a partner can be accessed from either the host device or the terminal device using, for example, a telephone number. Then, a predetermined registration process is executed so that the terminal device can be appropriately operated in the communication system. This is because, for example, in a case where the terminal device is a system that can acquire paid information from the host device, it is necessary for management to prevent an unregistered terminal device from illegally acquiring information from the host device. Is also an important process.
[0003]
  In this registration process, first, terminal identification information, which is a unique number for each of a plurality of terminal devices in the communication system, and a subscriber number for an information communication network such as a telephone number are transmitted from the terminal device to the host device. In the host device, for example, a management table is prepared, and the registration processing is performed by storing the terminal identification information and the subscriber number in association with each other. At this time, conventionally, a method is adopted in which a person who desires to register a terminal inputs a subscriber number such as the terminal identification information and a telephone number via an operation button or the like provided in the terminal device. It was. The terminal device then notifies the host device of the input terminal identification information and subscriber number.
[0004]
[Problems to be solved by the invention]
  However, in the conventional registration method described above, even if there is an input error of terminal identification information or a subscriber number by a registration applicant, the notified host device can only grasp them as correct. Therefore, for example, if the same subscriber number is not already registered in the management table, it is unconditionally registered.
[0005]
  If wrong terminal identification information or subscriber number is registered in this way, various inconveniences occur. For example, when trying to access a terminal device from a host device, if the subscriber number is a telephone number, a so-called erroneous call will occur. And if the host device has a function to retry a predetermined number of times when it cannot access the terminal device, it will be accessed with the wrong telephone number over and over, and the access target will be normal If it is a telephone, it will behave like a so-called “mischievous telephone”.
[0006]
  In order to solve the above-described problems, the present invention can register a terminal device only when the terminal identification information transmitted from the terminal device and the subscriber number to the information communication network are correct. In the systemEndAn object is to provide a terminal device.
[0007]
[Means for Solving the Problems and Effects of the Invention]
  In order to achieve this object, the invention according to claim 1, wherein the host device and a plurality of terminal devices are connected via an information communication network,Furthermore, terminal identification information for identifying each of the plurality of terminal devices is set, and either the host device or the terminal device can be set as a partnerAccessible communication systemThe terminal identification information and an input means for a terminal registration applicant to input a subscriber number to the information communication network, the terminal identification information input by the input means, and the A registration information storage means for storing a subscriber number, and the terminal identification information and the subscriber number stored in the registration information storage means are transmitted to the host device, and communication with the host device is temporarily disconnected. And registration control means for transmitting the terminal identification information stored in the registration information storage means to the host apparatus in accordance with an instruction from the host device, and the terminal identification information by the registration control means. And the subscriber number is transmitted to the host device, and after disconnecting communication with the host device, if there is no access from the host device within a predetermined time, As unregistered handling process of the constant, the terminal apparatus characterized by performing a process of displaying on the display means the effect that the entered terminal identification information and the subscriber number is wrong by the input meansIt is.
[0008]
  Of the present inventionTerminal deviceAccording to the terminal identification information and subscriber numberTheSend to the deviceTo do.Host deviceThenThen, a predetermined registration process to be managed in the communication system is executed using the transmitted terminal identification information and subscriber number. However, the terminal identification information and the subscriber number transmitted from the terminal device are not used as they are, but the following confirmation process is executed. That is, after the host device stores the terminal identification information and the subscriber number from the terminal device, the communication between both devices is temporarily disconnected, and for confirmation, the host device uses the stored subscriber number to the terminal. The device is accessed, and terminal identification information is transmitted from the terminal device accessed by the host device to the host device. Then, the host device determines whether or not the transmitted terminal identification information corresponds to the subscriber number used when accessing the terminal device before that. If the correct subscriber number is notified from the terminal device, the corresponding terminal identification information stored in the host device should be transmitted. If so, a predetermined registration process is performed. Execute. If the transmitted terminal identification information does not correspond to the subscriber number, at least the subscriber number is incorrect. In this case, the registration process is not executed.
[0009]
  Therefore, the registration control means of the terminal device of the present invention transmits the terminal identification information and the subscriber number stored in the registration information storage means to the host device, temporarily disconnects the communication with the host device, and further In accordance with an instruction from the apparatus, the terminal identification information stored in the registration information storage means is transmitted to the host apparatus.
  Therefore, when registering a terminal device, it can be registered only when the terminal identification information transmitted from the terminal device and the subscriber number to the information communication network are correct. Thereby, the following points cited as problems of the prior art can be solved. In other words, if the subscriber number is a telephone number and it is registered with the wrong number, when the host device accesses with the registered number, it becomes a so-called wrong call, and in particular has a retry function. If the access target is a regular phone, it will behave like a “mischievous phone call”, but with this method, the subscriber number is correct. Since only registration is performed, such inconvenience does not occur.
[0010]
  The predetermined registration process is a process for making a management target in the communication system, for example, a process of storing terminal identification information and a subscriber number in a management table in the host device. Furthermore, a process for notifying the terminal device that registration has been completed may be added. When the terminal device receives the notification of the completion of registration, for example, if a display device is provided in order to notify the owner or the like, the fact that the registration has been completed is displayed on the display device. It is possible to do so.
[0011]
  By the way, although the terminal identification information and the subscriber number transmitted from the terminal device are both wrong, it is also very low in probability that it is the same as the terminal identification information and the subscriber number of another terminal device. It can be considered in theory. In this case, registration of the terminal device that transmitted the terminal identification information and the subscriber number is not executed, but since the correspondence between the terminal identification information and the subscriber number is correct, the behavior such as the “mischievous phone call” described above is not performed. However, there is no inconvenience in that respect.
[0012]
[0013]
[0014]
[0015]
  The terminal device of the present inventionBecause the terminal registration applicant uses a configuration that inputs the terminal identification information and subscriber number using the input means, input errors are likely to occur.Yes.
[0016]
  Therefore, the present inventionIn the terminal device,in frontWhen the registration control means transmits the terminal identification information and the subscriber number to the host device, and once disconnects from the host device, there is no access from the host device within a predetermined time. Execute the predetermined unregistered response processThe
[0017]
  This is because if the correct subscriber number is transmitted to the host device, the host device should be accessed from the host device after the communication has been cut off. This means that at least the subscriber number is incorrect. Therefore, the unregistered response process is executed. As this unregistered processingAnd executing a process of displaying on the display means that the terminal identification information or the subscriber number input by the input means is incorrect..
[0018]
  By this notification, the owner of the terminal device who has noticed an error can now input the correct subscriber number and terminal identification information, and if the information is sent again to the host device, the registration process is executed this time. The Rukoto. As described above, if the registration process in the host device is to notify the terminal device that the registration has been completed in addition to the registration in the management table, for example, When this registration completion notification is received, it may be possible to display a message indicating that the registration has been completed on a display device or the like in order to notify the owner or the like.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, a communication system as an embodiment to which a registration method of the present invention is applied will be described with reference to the drawings.
  FIG. 1 is a block diagram showing a schematic configuration when a communication system is applied to a system related to karaoke and a configuration of a karaoke terminal 10 as a “terminal device” which is a component of the system.
[0020]
  As shown in FIG. 1, in the communication system of the present embodiment, an information center 3 as a “host device” in charge of distribution related processing of karaoke song information and a plurality of karaoke terminals 10 are connected via an information communication network 7. Connected and configured.
  First, the configuration of the karaoke terminal 10 will be described.
[0021]
  The karaoke terminal 10 controls the entire apparatus, a central control device 31 corresponding to “registration control means”, a multipurpose input key 32 corresponding to “input means”, and a storage means corresponding to “registration information storage means”. A hard disk 33, a calendar clock 34 that constantly counts the current date and time and notifies the central control device 31, a sound reproduction circuit 35, a screen display control device 26, and a communication control device 27 that can be connected to the information communication network 7. I have. A mixer amplifier 38 is connected to the audio reproduction circuit 35, and a television monitor 29 as a display means is connected to the screen display control device 26. Further, a speaker 41 and a microphone 43 are connected to the mixer amplifier 38.
[0022]
  The multi-purpose input key 32 includes various keys, and is used for operations such as selecting a karaoke song, connecting to the information center 1, and inputting a telephone number or an ID number as a registration preparation process on the terminal side described later. Is done.
  The communication control device 27 is used for data communication with the information center 3 through the information communication network 7 which is a telephone carrier side equipment, and modulates digital data into a voice band and digital data of a received voice band signal. Demodulate to.
[0023]
  The karaoke terminal 10 receives karaoke song information necessary for performing karaoke performance from the information center 3 and stores / stores it in the built-in hard disk 33. The karaoke song information for one song stored in the hard disk 33 is composed of song number information and entity information which are identification information for identifying songs. The entity information includes MIDI (Musical Instrument Digital Interface) standard performance information, which is information on accompaniment music, lyrics information, timing information for specifying the timing of switching and changing colors, background video information, and the like. ing. The background video information is obtained by encoding video information corresponding to each song.
[0024]
  The karaoke terminal 10 has the above-described configuration, and is a device for actually performing karaoke performance in response to a karaoke user's request. At the time of karaoke performance, the central control device 31 executes karaoke performance processing in accordance with a predetermined karaoke performance program. The information is transferred to the audio reproduction circuit 35, and the lyrics information and the background video information are transferred to the screen display control device 26, respectively. The performance information output to the audio reproduction circuit 35 is converted into an analog performance signal, then sent to the mixer amplifier 38 to be electrically amplified, and the user's singing voice input through the microphone 43 and an appropriate level. Mixed at a rate. The mixed audio signal is output to the outside as a performance sound by the speaker 41.
[0025]
  On the other hand, the lyric information output in synchronization with the performance information is combined (superimposed) with the background video information reproduced by the screen display control device 26 and displayed on the television monitor 29. As a result, the TV monitor 29 is displayed with the lyrics telop combined with the background video.
[0026]
  It has been described that karaoke song information necessary for performing karaoke performance is supplied from the information center 3 and stored in the built-in hard disk 33. The songs released in the past can be supplied together or installed on the user side as the karaoke terminal 10 stored in the hard disk 33 in advance. 3 is sequentially supplied to the karaoke terminal 10 via the information communication network 7 and replenished.
[0027]
  In this case, a format is adopted in which the karaoke terminal 10 inquires the information center 3 periodically, for example, once a day or once every 10 days, and if there is a new song, it is distributed. The hard disk 33 stores a transmission time for inquiring about the distribution of new songs, and the central control device 31 transmits to the information center 3 and makes an inquiry when this transmission time comes.
[0028]
  In order to receive a service such as new song distribution from the information center 3, it is necessary to execute a predetermined registration process to be managed in the communication karaoke system. That is, the information center 3 provides a service only to the karaoke terminal 10 that is recognized as a management target through a predetermined registration process. The contents of this registration process will be described later.
[0029]
  Next, the configuration and function of the information center 3 will be described.
  As shown in FIG. 2, the information center 3 includes a communication control device 77 connected to the karaoke terminal 10 via the information communication network 7, and a storage device 73 that stores karaoke song data distributed to the karaoke terminal 10. Are controlled by a host computer 71 as a central control unit. Various devices such as an input device 75, a printer 79, and a CRT 81 are connected to the host computer 71. In addition to the karaoke song data, the storage device 73 stores various control programs for operating the host computer 71 and the like.
[0030]
  The information center 3 configured as described above distributes the karaoke song data to each karaoke terminal 10 via the information communication network 7. This distribution is performed from the information center 3 side at a pace of every few days for the addition of new song data, but in this embodiment, a regular new song from the karaoke terminal 10 side (for example, once a day). In response to the inquiry, if there is a new song to be distributed, the distribution process is performed.
[0031]
  As described above, the information center 3 provides a service only to the karaoke terminal 10 that is recognized as a management target through a predetermined registration process. Therefore, a management table 73a as shown in FIG. 3 is stored in the storage device 73. For the karaoke terminal 10 that is officially registered as a management target in the management table 73a through a predetermined registration process. After that, it will provide services such as new song distribution. As shown in FIG. 3, the management table 73a records an ID number, a telephone number, and a registration state. The ID number is identification information set such that each of the plurality of karaoke terminals 10 connected to the information center 3, that is, the plurality of karaoke terminals 10 belonging to the communication system, has a unique number. It may be a device number assigned to each. The telephone number corresponds to “a subscriber number to the information communication network”. The details of the registration state will be described later. For example, it is used to record, for example, “0” or “1” indicating that the registration is officially completed or that the registration is abnormal.
[0032]
  Next, the operation of this system having the above configuration will be described.
  First, operation | movement of the karaoke terminal 10 is demonstrated based on the flowchart of FIGS.
  When the power is turned on, the main routine of FIG. 4 is started.
[0033]
  First, in the first step S1, initialization of the entire device such as resetting of the communication control device 27 is performed. Next, in S2, it is checked whether or not the karaoke performance mode is designated as the operation designation of the karaoke terminal 10. If the karaoke terminal installation company designates the karaoke performance mode, the process proceeds to S3, and if not designated, the process proceeds to S4.
[0034]
  In S3, karaoke performance processing is performed. Since the outline of this karaoke performance process has been described in conjunction with the above-described configuration description, it will be omitted here.
  In S4, it is checked whether or not the registration processing mode is designated as the operation designation of the karaoke terminal 10. If there is a mode designation for executing the registration process by the karaoke terminal installation company, the process proceeds to S5, and if there is no such designation, the process proceeds to S6.
[0035]
  In S5, the subroutine SUB1 is called to perform a predetermined registration process. This registration process will be described with reference to the flowchart of FIG.
  This registration process is a process for enabling the provision of services such as new song distribution by being registered on the information center 3 side as an effective karaoke terminal 10 in the communication system. Before installing the karaoke terminal 10, it is difficult to notify and register information such as a telephone number and an ID number to the system administrator side in terms of system operation. The telephone number and the ID number are input and stored, and the karaoke terminal 10 is caused to trigger the registration process start as the entire system in the form of terminal transmission.
[0036]
  First, in S11, the telephone number and ID number on the karaoke terminal 10 side are received by the initial setting function. This can also be performed while displaying guidance such as an input procedure using the television monitor 29, for example. For example, when the registration mode is selected by an operation using the multi-purpose input key 32, a telephone number / ID number input field and a text prompting input are displayed on the television monitor 29. Accordingly, when the user operates the multi-purpose input key 32 to input those numbers and, for example, instructs to confirm the input contents, both the numbers are stored in the hard disk 33, and the process of S11 ends.
[0037]
  Next, as S12, communication processing with the information center 3 is started.
  If the connection with the information center 3 is completed, the telephone number and the ID number stored in the hard disk 33 are transmitted to the information center 3 in S13 to make a registration request. When this transmission process ends, the connection with the information center 3 is once released in S14.
[0038]
  Then, in S15, it is determined whether or not there is a connection request from the information center 3. If there is no connection request from the information center 3 (S15: NO), the process proceeds to S22 to determine whether it is timed out. If not timed out (S22: NO), the process returns to S15 and waits for a connection request from the information center 3. .
[0039]
  If there is a connection request from the information center 3 (S15: YES), the information center 3 is connected in S16, and it is determined whether an ID number transmission instruction is issued from the information center 3 in the subsequent S17.
  If an ID number transmission instruction is given (S17: YES), the process proceeds to S18, and the ID number stored in the hard disk 33 (that is, the ID number input in S11) is transmitted to the information center 3.
[0040]
  Thereafter, in S19, it is determined whether or not information indicating “registration completed” has been received from the information center 3. If not received (S19: NO), the process proceeds to S25 to determine whether or not a timeout has occurred. If it is not timed out (S25: NO), the process returns to S19 and waits for reception of information indicating "registration complete" from the information center 3.
[0041]
  When information indicating “registration completion” is received from the information center 3 (S19: YES), a registration completion handling process is executed in S20. This is a process of storing information indicating that registration is complete in the hard disk 33, for example. The operation that can be performed by the karaoke terminal 10 in the future and the operation that cannot be performed may be controlled depending on whether or not information indicating that the registration is completed is stored. For example, in the case of contents that can be requested to the information center 3 only when it is officially registered in the system, it is first determined whether or not information indicating that registration is complete is stored. It can be considered not to execute it if there is no.
[0042]
  After the process of S20 is complete | finished, it transfers to S21 and the connection with the information center 3 is cancelled | released. After the process of S21, the present registration process routine is terminated, and the process proceeds to S6 of FIG.
  The series of processes in S11 to S21 described above is a case where a correct telephone number and ID number are transmitted to the information center 3. As will be described later in the processing in the information center 3, the information center 3 tries to connect by calling using the telephone number transmitted by the karaoke terminal 10 in S13 after releasing the connection in S14. Therefore, if the correct telephone number is transmitted, there should be a connection request from the information center 3 to the own karaoke terminal 10, but if the wrong telephone number is transmitted, the information center 3 is not transmitted to the own karaoke terminal 10. Connection requests never come from.
[0043]
  Therefore, if the determination in S22 is affirmative, that is, if a time-out occurs without a connection request from the information center 3, the process proceeds to S23 and a predetermined unregistered response process is executed. As this unregistered processing, for example, in order to notify the user that the telephone number or ID number input in S11 is incorrect, it is possible to display that fact on the television monitor 29, for example. By this display, if a user who notices an error inputs the correct telephone number and ID number and transmits them to the information center 3 again, the processing from S16 to S21 is executed, and the formal registration is completed. It will be. As described above, since at least the telephone number is wrong in this case, it is necessary to notify the user to that effect.
[0044]
  After the unregistered response process in S23, the main registration process routine is terminated, and the process proceeds to S6 in FIG.
  In the case of negative determination in S17, that is, when there is a connection request from the information center 3, but the connection from the information center 3 is not an ID number transmission instruction, the process proceeds to S24. A predetermined response process is executed. This is not because there was a connection request from the information center 3 in the series of processes of S11 to S21 described above, but after the connection with the information center 3 was canceled in S14, the connection request happened to be accompanied by another process in the information center 3. It is a case, and it is not a registration related process anyway. Therefore, for example, predetermined response processing such as displaying the fact on the television monitor 29 is executed. In this case, since it is connected to the information center 3 in S16, after the process of S24 is completed, the process proceeds to S21 and the connection with the information center 3 is released.
[0045]
  Further, in S25, an affirmative determination is made, that is, a time-out occurs while no information indicating “registration complete” is received from the information center 3 even though the ID number is transmitted in response to the ID number transmission instruction from the information center 3. When it has become, it transfers to S26 and performs a predetermined | prescribed response process. This is because there is a trouble on the information center 3 side or a transmission path such as the information communication network 7 in spite of the ID number transmission instruction from the information center 3 in the series of processes of S11 to S21 described above. There are cases. In addition, it is not related to the series of registration processes of S11 to S21, and it may happen that there is an ID number transmission instruction that happens to be accompanied by another process in the information center 3. Therefore, for example, the user is notified by displaying, for example, on the television monitor 29 that the registration process itself has not been completed including its cause.
[0046]
  In this case as well, since the information center 3 is connected in S16, after the process of S26 is completed, the process proceeds to S21, the connection with the information center 3 is released, and the registration process routine is ended. The process proceeds to S6.
  Returning to the description of the processing in FIG. 4, in S <b> 6, it is determined whether or not there is a connection request from the information center 3. If there is a connection request, the process proceeds to S7, and if not specified, the process proceeds to S2.
[0047]
  In S7, the subroutine SUB2 is called and processing corresponding to the connection request from the information center 3 is executed. The processing of this subroutine SUB2 will be described with reference to the flowchart of FIG.
  In the first step S31 of FIG. 6, the information center 3 is connected. In the next S32, it is determined whether or not the new song is distributed from the information center 3. If the new song is distributed (S32: YES), the karaoke song information related to the new song is received in S33 and the hard disk 33 is received. To accumulate.
[0048]
  When the process of S33 is completed, the process proceeds to S34 and the connection with the information center 3 is released.
  On the other hand, if a negative determination is made in S32, that is, if it is not the distribution of a new song, the process proceeds to S35, where it is determined whether or not there is an ID number transmission instruction from the information center 3. If an ID number transmission instruction is given (S35: YES), the process proceeds to S36, and the ID number stored in the hard disk 33 is transmitted to the information center 3. Thereafter, the process proceeds to S34.
[0049]
  If it is not an instruction to send an ID number (S35: NO), the process proceeds to S37 and other corresponding processing is executed. For example, this is a process of transmitting a log if the operation result information (log) is an upload instruction. Thereafter, the process proceeds to S34.
[0050]
  After the process of S34, this subroutine is finished and the process proceeds to step S2 in the flowchart of FIG.
  The determination in S35 of FIG. 6 is described on the assumption that there is an ID number transmission instruction from the information center 3. Although this has been described in the registration process in FIG. 5, the karaoke terminal 10 transmits a telephone number to the information center 3 in S13 while the registration process in FIG. 5 is being executed. As a result, when an instruction to transmit an ID number is issued from the information center 3, it can be determined in S17. However, if the telephone number transmitted by the karaoke terminal 10 is incorrect, the information center 3 instructs another karaoke terminal 10 to transmit the ID number. That is, the registration process of FIG. 5 is not executed, but an ID number transmission instruction is issued from the information center 3. In this case, the ID number is transmitted in S36 of FIG. 6 because the information center 3 uses it for a predetermined determination in the information center side processing described later.
[0051]
  The above is the operation of the central control device 31 of the karaoke terminal 10 and performs various processes such as karaoke performance processing, registration processing, and reception of karaoke song information related to new songs.
  Next, the operation of the information center 3 will be described based on the flowcharts of FIGS. In the information center 3, after the power is turned on, the process is executed from step S101.
[0052]
  In S101, initialization of the entire apparatus such as resetting of the communication control apparatus 77 is performed. After finishing the process of S101, it transfers to S102 and it is investigated whether there exists a connection request from the karaoke terminal 10. FIG. If there is a connection request, the process proceeds to S103, and if not, the process of S102 is repeated to enter a standby state.
[0053]
  In S103, in response to the connection request from the karaoke terminal 10, the karaoke terminal 10 is connected. After the connection is completed, the process proceeds to S104, and it is determined whether or not a registration request is made from the karaoke terminal 10. When the registration request processing from the karaoke terminal 3 shown in S13 of FIG. 5 is executed, it is determined that the request is a registration request (S104: YES), the process proceeds to S105 and the subroutine SUB3 is called to call a predetermined center side. Perform the registration process. This process will be described later. On the other hand, if it is not a registration request (S104: NO), the process proceeds to S106 to execute other corresponding processing.
[0054]
  When the process of S105 or S106 is completed, the process proceeds to S107, and it is determined whether or not it is a new song information distribution time. In the present embodiment, as described above, for example, a new song is distributed every month or every other week, and it is determined whether or not it is the distribution time. And if it is a delivery time, it will transfer to S108. In S1087, karaoke song information distribution processing for the new song is performed. When the process of S108 is completed, or when it is determined that the distribution time is not reached in S36, the process returns to S102.
[0055]
  Next, the processing of the subroutine SUB3 executed in S105 will be described with reference to the flowchart of FIG.
  First, in S111, the telephone number and ID number transmitted from the karaoke terminal 10 are received. In S112, these two numbers are provisionally registered in the management table 73a of the storage device 73. For example, the telephone number and the ID number are written in the management table 73a shown in FIG. 3, and “0” indicating temporary registration is written in the registration status column.
[0056]
  When the temporary registration process in S112 is completed, the connection with the karaoke terminal 10 is once released in S113.
  In subsequent S114, a call is made and connected using the telephone number temporarily registered in the management table 73a in S112. In step S115, an ID number transmission instruction is sent to the connection partner.
[0057]
  Thereafter, in S116, it is determined whether an ID number has been received from the connection partner. If no ID number has been received (S116: NO), the process proceeds to S123 to determine whether or not a timeout has occurred. If not (S123: NO), the process returns to S116 and waits to receive an ID number. When the ID number is received (S116: YES), the process proceeds to S117.
[0058]
  In S117, the correspondence relationship between the received ID number and the telephone number used for calling / connecting in S114 is checked, and it is determined in S118 whether or not they match. Specifically, whether the ID number provisionally registered in the management table 73a as the ID number corresponding to the telephone number used for calling / connection in S114 matches the received ID number. Judge.
[0059]
  If they match (S118: YES), the process moves to S119, and is officially registered in the management table 73a. This is done, for example, by writing “1” indicating official registration in the registration status column where “0” has been written as temporary registration in the management table 73a shown in FIG.
[0060]
  Thereafter, in S120, in order to notify the karaoke terminal 10 that the registration in the information center 3 is completed, information indicating “registration completed” is transmitted. Thereafter, the connection with the karaoke terminal 10 is canceled in S122, the present subroutine SUB3 is terminated, and the routine proceeds to S107 in FIG.
[0061]
  When “1” indicating official registration is written in the registration status column of the management table 73a as described above, for example, at the karaoke terminal 10 to be distributed when new song information is distributed in S108. It is treated as an official management target, such as being judged to be.
[0062]
  A series of processes in S111 to S120 and S122 described above is a case where a correct telephone number and ID number are transmitted from the karaoke terminal 10. If the correct telephone number is received in S111, the partner connected in S114 is the partner's karaoke terminal 10 that received the telephone number in S111, but if the wrong telephone number is received, S114 There is a possibility that the connection partner is not the karaoke terminal 10, and in that case, there is a possibility that no reply will be received even if an instruction to send the ID number is given.
[0063]
  Therefore, if an affirmative determination is made in S123, that is, if a timeout occurs before the ID number is transmitted from the karaoke terminal 10, the process proceeds to S124 and is stored as a registration abnormality. This is done, for example, by writing “2” indicating that the registration is abnormal in the registration status column in which “0” has been written as temporary registration in the management table 73a shown in FIG.
[0064]
  In the case of a negative determination in S118, that is, if the ID number is received from the connection partner in S114 but does not match the ID number temporarily registered in the management table 73a, The process proceeds to S124 and is stored as a registration abnormality. This is the case, for example, when an incorrect telephone number is received, but the incorrect telephone number is that of another karaoke terminal 10.
[0065]
  Note that the cause is different between the case where an affirmative determination is made in S123 and the process proceeds to S124, and the case where a negative determination is made in S118 and the process proceeds to S124. . For example, when an affirmative determination is made in S123 and the process proceeds to S124, “2” is written in the registration status column of the management table 73a (FIG. 3) as described above, and a negative determination is made in S118 and the process proceeds to S124. "3" is written in the registration status column.
[0066]
  The operation of the host computer 71 of the information center 3 has been described above, and in accordance with a registration request from the karaoke terminal 10, processing such as predetermined registration processing and new song information distribution processing is performed.
  A series of processing in the karaoke terminal 10 and the information center 3 up to the formal registration in the present embodiment is shown in a communication sequence diagram as shown in FIG.
[0067]
  First, the karaoke terminal 10 attempts a call connection to the information center 3 through the information communication network 7. In the information center 3, the incoming call is received in response to the outgoing call from the karaoke terminal 10, and the incoming call OK is transmitted. In the karaoke terminal 10, after receiving this incoming call OK, the telephone number and the ID number are transmitted to the information center 3.
  After the information center 3 receives and temporarily registers the telephone number and the ID number, the connection between the information center 3 is temporarily disconnected, and this time the information center 3 makes a call connection with the telephone number temporarily registered. The karaoke terminal 10 receives a call from the information center 3 and transmits an incoming call OK. After receiving this incoming call OK, the information center 3 sends an ID number transmission instruction to the karaoke terminal 10.
[0068]
  The karaoke terminal 10 receives this ID number transmission instruction and transmits the ID number to the information center 3.
  The information center 3 receives this ID number and collates it with the temporarily registered ID number. If both match, “registration complete” is transmitted to the karaoke terminal 10. After the karaoke terminal 10 receives this “registration complete”, the connection between the two is disconnected.
[0069]
  As is clear from the above description, when the karaoke terminal 10 performs registration for the communication system to be managed, a user (or owner, etc.) of the karaoke terminal 10 inputs using the multipurpose input key 32. The telephone number and the ID number are transmitted to the information center 3, and the information center 3 executes a predetermined registration process using the transmitted telephone number and ID number. However, the telephone number and ID number transmitted from the karaoke terminal 10 are not used unconditionally, but a process for confirming whether the number is correct is executed.
[0070]
  That is, after the information center 3 temporarily registers the telephone number and ID number from the karaoke terminal 10 in the management table 73a, the communication between the devices 3 and 10 is temporarily disconnected, and the temporarily registered telephone for confirmation. The karaoke terminal 10 is accessed from the information center 3 using the number, and the ID number is transmitted to the information center 3 from the karaoke terminal 10 accessed from the information center 3. Then, the information center 3 determines whether or not the transmitted ID number corresponds to the telephone number used when accessing the karaoke terminal 10 before that. If the correct telephone number is notified from the karaoke terminal 10, the corresponding ID number stored in the information center 3 should be transmitted. If so, a predetermined registration process is performed. Execute. If the transmitted ID number does not correspond to the telephone number, at least the telephone number is incorrect, and in this case, formal registration is not executed.
[0071]
  Therefore, when registering the karaoke terminal 10, it can be registered only when the ID number and the telephone number transmitted from the karaoke terminal 10 are correct. Thereby, the following points cited as problems of the prior art can be solved. In other words, if you register with the wrong phone number, if the information center 3 accesses with the registered phone number, it becomes a so-called wrong call, especially if you have a retry function, it will be wrong many times. Since access is made with a phone number, if the access target is a normal phone, it will behave like a “mischievous phone”, but this method will only register if the phone number is correct. There is no inconvenience.
[0072]
  By the way, both the telephone number and the ID number transmitted from the karaoke terminal 10 are wrong, but it is theoretically very low that the telephone number and the ID number of another karaoke terminal 10 are the same. Is considered. In this case, the registration of the karaoke terminal 10 that has transmitted the telephone number and the ID number is not executed, but the correspondence between the ID number and the telephone number is correct, so that the behavior such as the “mischievous telephone” described above is not performed. There is no point inconvenience.
[0073]
  In the case of the present embodiment, “0” indicating that is stored in the registration status column of the management table 73a in the case of provisional registration, and the registration status column in the management table 73a in the case of formal registration. Is updated to “1” indicating that. In this way, services such as distribution of new songs can be provided only to the officially registered karaoke terminal 10.
[0074]
  If the above-described collation by telephone number cannot be performed, or if collation has not been performed, “2” or “3” indicating registration error is displayed in the registration status column of the management table 73a. Since it is memorized, it is useful for investigating the cause of registration abnormality. For example, when the ID number B is transmitted as a result of access using the telephone number transmitted from the karaoke terminal 10 whose ID number is A, the karaoke terminal 10 whose ID number is A You can see that it is wrong.
[0075]
  Furthermore, although the information center 3 is accessed using the temporarily registered telephone number and the ID number is transmitted from the accessed karaoke terminal 10 to the information center 3, the ID number is not transmitted within a predetermined time. In such a case, there is a high possibility that the connection partner is not the karaoke terminal 10, and since the connection is made with a telephone number in particular, there is a possibility that an ordinary telephone is being accessed. Therefore, it is important to stop access anyway when the ID number is not transmitted within a predetermined time. In this case, it is also preferable to take measures to prohibit access by this telephone number in the subsequent processing.
[0076]
  On the other hand, in the karaoke terminal 10, when formal registration is not possible, the fact is displayed on the TV monitor 29 or the like. A number and an ID number can be input. If these numbers are sent again to the information center 3 to request registration, a formal registration process is executed.
[0077]
  The present invention is not limited to such embodiments as described above, and can be implemented in various forms without departing from the gist of the present invention.
  For example, in the above-described embodiment, the user also inputs the ID number. However, if the apparatus number is uniquely set at the time of manufacture, for example, the apparatus number can be used as the ID number. In that case, the apparatus number can be stored in the hard disk 33 or the like at the time of manufacture, and can be automatically read and transmitted to the information center 3 without being input by the user. However, even in that case, it is common that only the user who wants to register the telephone number knows, so it is still necessary to have the user input it directly. This mistaken input of the telephone number causes various inconveniences as described above, and thus is effective even when only the telephone number is input.
[0078]
  Needless to say, the application target of the present invention is not limited to the communication karaoke system, but may be applied as a game software distribution network or the like.
