Embodiment 1
One embodiment of the present invention will be described below with reference to FIGS. 1 to 7.

(Outline of connection destination determination system 100)
First, the outline of the connection destination determination system 100 (communication system) will be described with reference to FIG. FIG. 2 is a diagram showing an outline of the connection destination determination system 100. As shown in FIG. The connection destination determination system 100 of the present embodiment implements a nuisance call rejection service. The connection destination determination system 100 includes telephones 1a and 1b (communication devices), a distribution server 2, and management servers 3a and 3b, as shown in FIG. Hereinafter, when there is no need to distinguish between the telephones 1a and 1b and the management servers 3a and 3b, they may be expressed as "telephone 1" and "management server 3", respectively.

  The above-mentioned nuisance call rejection service is a service for rejecting an unwanted call from the telephone 1. In addition, the connection destination determination system 100 refers to the usage history, usage status, and the like of the telephone 1 using a PC (personal computer) (not shown) by the user, and notifies the user of these usage history, usage status, etc. To realize a web management service. The PC may be a cellular phone (including a smartphone), a tablet, or the like as long as the PC is a communication terminal connectable to the Internet network.

  The telephone set 1 is communicably connected to the distribution server 2 and the management server 3 via a telephone line network. At the time of shipment, the telephone set 1 stores the distribution server telephone number which is the telephone number of the distribution server 2 and stores the management server telephone number which is the telephone number of the management server 3 as shown in FIG. Not. That is, the telephone 1 is communicably connected to the distribution server 2 in the first connection. Then, as shown in (a) of FIG. 2, the telephone set 1 acquires the management server telephone number from the distribution server 2. In FIG. 2A, the telephone set 1a acquires "1111" which is a management server telephone number of the management server 3a, and the telephone 1b acquires "2222" which is a management server telephone number of the management server 3b. That is, the telephone set 1 acquires the management server telephone number of one management server 3 among the plurality of management servers from the distribution server 2. In other words, the telephone set 1 acquires the management server telephone number of the management server 3 (designated management server) designated by the distribution server 2 from among the plurality of management servers.

  The telephone 1 can communicate with the management server 3 without accessing the distribution server 2 using the acquired management server telephone number in the second and subsequent connections, as shown in (b) of FIG. Connecting. In (b) of FIG. 2, as the management server telephone number acquired from the distribution server 2 (see (a) of FIG. 2), the telephone set 1a accesses the management server 3a and the telephone set 1b can communicate with the management server 3b. I have access to

  The telephone set 1 is communicably connected to the management server 3 to acquire data of the nuisance number list managed by the management server 3 from the management server 3 and manages the nuisance call list of the own machine. Specifically, the telephone set 1 accesses the management server 3 at predetermined intervals (for example, once a day), acquires data for updating to the latest version of the nuisance call list, and the own machine manages it. Update the junk phone list. By this, it is possible to reject an unwanted call from the latest nuisance call list. Further, the telephone 1 transmits various information such as usage history information (including a calling operation or information related to calling by the calling operation) indicating the usage history of each telephone 1 by the user to the management server 3 at the time of the access, for example. . In addition, the telephone set 1 manages, for example, nuisance call information indicating a phone number (junk number) determined to be a nuisance call, which has received an incoming call to the telephone set 1 used by each user, through a telephone line network as necessary. Send to 3

  As described above, the distribution server 2 determines (designates) the management server 3 to which the telephone set 1 is connected, and transmits the determined management server telephone number of the management server 3 to the telephone set 1. Specifically, the distribution server 2 determines the management server 3 to which the telephone set 1 is connected, using the terminal information on the telephone set 1 acquired from the telephone set 1. The details of the terminal information will be described later.

  The management server 3 manages various information received from the telephone 1 (or PC). Also, the management server 3 manages the above-described nuisance call list. The management server 3 updates the nuisance call list using the nuisance call information provided by the police, a trader or the like, or the nuisance call information received from the telephone 1. Further, the management server 3 refers to the incoming call history information received from the plurality of telephones 1 and describes the telephone numbers of which the incoming call is rejected by a predetermined number or more of telephones in the nuisance number list. In addition, the telephone numbers permitted to be received by the telephone 1 of a predetermined number or more are deleted from the junk number list. The management server 3 updates the data of the junk phone list (at first, all the data of the junk phone list, and thereafter, to the latest version of the junk phone list) every predetermined period (for example, when there is access from the telephone 1). To the telephone set 1). Thereby, the latest nuisance call list can be provided to all users who subscribe to the nuisance call rejection service. The first nuisance call list registered in the management server 3 may be generated based on the nuisance call information provided by the police, a trader, or the like.

  As described above, at the first connection after shipment, the telephone set 1 accesses the distribution server 2 using the stored distribution server telephone number, and the management server of the management server 3 to which the own machine is connected Get a phone number. Then, at the time of the second and subsequent connections, the management server 3 is accessed using the acquired management server telephone number. That is, when the telephone set 1 is shipped, only the distribution server telephone number common to the telephone sets 1 may be stored in the telephone set 1. Therefore, compared with the case where the management server telephone number of the management server 3 to which each telephone set 1 is to be accessed without storing the distribution server 2 is stored in each telephone set 1 at the time of shipment, improvement of work efficiency at work and work cost Can be realized.

(Principal configuration of the telephone 1)
Next, with reference to FIG. 1, the main configuration of the telephone 1 according to the present embodiment will be described. FIG. 1 is a block diagram showing an example of the main configuration of the telephone 1. As shown in FIG. As shown in FIG. 1, the telephone 1 includes a control unit 10, an operation unit 11, a storage unit 12, and a communication unit 16. In addition, although the telephone set 1 includes members (for example, a display, a speaker, a microphone, etc.) provided in a general telephone set, these members are thinly related to the present invention, so the description and details in FIG. Description is omitted.

  The control unit 10 integrally controls the functions of the telephone 1. The details of the control unit 10 will be described later. The operation unit 11 receives a user operation, and includes, for example, a touch panel, a physical button, and the like. When the operation unit 11 is a touch panel, it may be integrated with the display. The storage unit 12 stores various data used by the telephone 1. The details of the storage unit 12 will be described later. The communication unit 16 communicates with the distribution server 2 and the management server 3 to transmit and receive various information.

  The control unit 10 includes an initialization type determination unit 101 (operation determination unit), an initialization execution unit 102 (deletion unit), a connection destination determination unit 103, and a connection execution unit 104 (acquisition unit).

  The connection destination determination unit 103 assigns the connection destination of the telephone set 1 as the distribution server 2 or the management server 3. Specifically, the connection destination determination unit 103 refers to the storage unit 12 and stores the management server telephone number 123 (management server connection information) which is text data indicating the telephone number of the management server 3 to which the telephone 1 is connected. It is judged whether it is done or not. If it is stored, the connection destination is determined to be the management server 3, and the management server telephone number 123 is output to the connection execution unit 104. On the other hand, when the connection destination is not stored, the connection destination is determined to be the server 2, and the distribution server telephone number 122 (distribution server connection information) which is text data indicating the telephone number of the distribution server 2 is output to the connection execution unit 104. The distribution server telephone number 122 and the management server telephone number 123 are not limited to text data. For example, binary data, compressed data, etc. may be used.

  The connection execution unit 104 controls the communication unit 16 to execute connection to the distribution server 2 or the management server 3. Specifically, when the connection execution unit 104 receives the distribution server telephone number 122 from the connection destination determination unit 103, the connection execution unit 104 accesses the distribution server 2 using the distribution server telephone number 122. At this time, the connection execution unit 104 reads the terminal information 125 (device information) from the storage unit 12 and transmits it to the distribution server 2.

  Here, the details of the terminal information 125 will be described with reference to FIG. FIG. 3 is a view showing a data structure and a specific example of the terminal information 125. As shown in FIG. The terminal information 125 includes at least one of maker information, model information (model information), and specification information. Note that FIG. 3 shows an example in which the terminal information 125 includes all maker information, model information, and specification information for the convenience of description. The maker information is information indicating a maker who manufactured the telephone 1. The model information is information indicating the model of the telephone 1. The specification information is information indicating the specification of the telephone 1. The specification information changes, for example, in accordance with a communication carrier (carrier) that provides the telephone 1 to the user, or changes in accordance with an application installed in the telephone 1 even with the same carrier. The data structure and specific example of the terminal information 125 are not limited to the example shown in FIG.

  Further, upon receiving the management server telephone number 123 and the next connection time 124 from the distribution server 2, the connection execution unit 104 stores these pieces of information in the storage unit 12. The information received from the distribution server 2 is not limited to the management server telephone number 123 and the next connection time 124. For example, the connection limit time indicating the upper limit of the connection time with the management server 3 may be received.

  On the other hand, when the connection execution unit 104 receives the management server telephone number 123 from the connection destination determination unit 103, the connection which is text data indicating the time to access the management server 3 next time is stored next time connection The time 124 is read. Then, when the current time (specifically, the current time of the place where the management server 3 is installed) is the time indicated by the connection time 124 next time, the management server 3 is notified using the management server telephone number 123 It accesses and exchanges information with the management server 3 concerned. Specifically, the connection execution unit 104 receives data including the next connection time 124. The connection execution unit 104 stores the received next connection time 124 in the storage unit 12. The data received from the management server 3 may include the above-described connection time limit.

  The initialization type determination unit 101 determines whether the instructed initialization is the first initialization including deletion of the management server telephone number 123 or does not include deletion of the management server telephone number 123 (management server telephone number 123). Do not delete) and determine if it is the second initialization. Here, initialization of the telephone 1 will be described with reference to FIGS. 4 and 5. FIG. 4 is a diagram showing an outline of distribution of the telephone set 1 and FIG. 5 is a diagram showing an outline of initialization of the telephone set 1.

  As shown in FIG. 4, the telephone 1 according to the present embodiment is rented to each carrier directly from the manufacturer A or through rental service providers B and C as one form of distribution, and each carrier to each user It will be rented. The carriers D to H may be different carriers or may include the same carrier (for example, the carrier D and the carrier F are the same carrier).

  Here, consider the case where the rental is finished and the user returns the telephone 1 to the carrier. When the telephone set 1 is returned, the carrier rents the telephone set 1 to another user. Therefore, the user (or carrier) needs to initialize the telephone 1 from the viewpoint of protection of personal information and the like. At this time, if the specifications of the telephone 1 do not change, even if the telephone 1 is rented to another user, there is no need to change the management server 3 to be accessed with the previous one. In addition, although the carrier may intentionally change the management server 3 accessed by the telephone 1 for the purpose of reducing the load on the management server 3, etc., even if the carrier does not desire such a change, There is no need to change the management server 3 to be accessed from the previous time. Therefore, in such a case, there is no need to delete the management server telephone number 123 in initialization, so the user (or the carrier) needs to perform the second initialization (management server telephone number 123 shown in FIG. 5A). It is sufficient to execute initialization (not delete).

  On the other hand, the management server telephone number 123 is garbled, and the management server telephone number 123 of the management server 3 to be accessed by the telephone 1 is changed due to the change of the management server 3 itself, etc. When it becomes impossible to access 3, the telephone set 1 needs to acquire the management server telephone number 123 again. In such a case, the user (or the carrier) needs to execute the first initialization (initialization for deleting the management server telephone number 123) shown in FIG. 5A. In addition, when the telephone set 1 is returned to the maker or the rental service provider, the next rental destination may have a different carrier (that is, the management server 3 accessed by the telephone set 1 is different). Even in such a case, since it is necessary to delete the management server telephone number 123 from the telephone set 1, the maker or the rental service provider needs to execute the first initialization.

  Since the management server telephone number 123 is deleted by executing the first initialization, the telephone set 1 (connection execution unit 104) accesses the distribution server 2 and acquires the management server telephone number 123. Here, after the telephone set 1a (see FIG. 2) in which the management server 3 to be accessed is the management server 3a (see FIG. 2) is returned, the carrier as the rental destination of the telephone set 1a is changed from the last rental time, and the terminal information 125 is changed. And consider the case where the first initialization is performed. In this case, as shown in (b) of FIG. 5, when the telephone set 1a accesses the distribution server 2 at the next rental destination, the new management server telephone number 123 (in the example of (b) of FIG. The management server telephone number 123 “3 222” is acquired. As described above, by making the management server telephone number 123 deletable, it is possible to cope with the case where the management server 3 to which the telephone set 1 should access changes.

  In the present embodiment, the user operation for executing the first initialization and the user operation for executing the second initialization are different. Therefore, when the initialization type determination unit 101 receives the operation information indicating the content of the user operation from the operation unit 11, the operation information indicates the first initialization or indicates the second initialization. It is determined whether it is one or not, and an instruction corresponding to the determination result is output to the initialization execution unit 102. Specifically, when determining that the initialization type determination unit 101 indicates the first initialization, the initialization type determination unit 101 outputs a first initialization execution instruction to the initialization execution unit 102. On the other hand, when it is determined that the second initialization is indicated, the execution instruction of the second initialization is output to the initialization execution unit 102.

  In response to an instruction from the initialization type determination unit 101, the initialization execution unit 102 executes the first initialization or the second initialization. Specifically, the initialization execution unit 102 deletes details of the first initialization and the details of the second initialization (various types of information stored in the telephone 1, and which information is not deleted. Information to be deleted is determined with reference to the initialization information 121 indicating. When the first initialization is performed, the initialization execution unit 102 deletes the next connection time 124 together with the management server telephone number 123. This is because the next connection time 124 is information related to the management server 3 currently accessed (specifically, the time determined by the management server 3). Further, the necessity of deleting various information other than the management server telephone number 123 and the next connection time 124 is not relevant to the present invention, and thus the description thereof is omitted here. However, in the first initialization, the information related to the currently accessed management server 3 is always deleted.

  The initialization execution unit 102 can recognize what state the telephone set 1 is (specifically, whether the telephone set 1 is being used by the user or the state before provision to the user). Is preferred. With such a configuration, when the first initialization is performed in the state of use by the user, the initialization execution unit 102 executes the first initialization in the state of use by the user. Is notified to the connection destination determination unit 103. The connection destination determination unit 103 receives the notification and outputs the distribution server telephone number 122 to the connection execution unit 104, whereby the connection execution unit 104 controls the communication unit 16 to access the distribution server 2, and the management server telephone is accessed. Get the number 123. Thereby, when the first initialization is executed in a state where the user is using it, in other words, when access to the management server 3 becomes impossible, access to the management server 3 is made promptly. It is possible to return to the possible state.

  The storage unit 12 stores at least the initialization information 121, the distribution server telephone number 122, the management server telephone number 123, the next connection time 124, and the terminal information 125. In addition, since the details of these pieces of information have already been described, the description here is omitted.

(Flow of telephone number acquisition process)
Next, the flow of the telephone number acquisition process executed by the telephone 1 will be described with reference to FIG. FIG. 6 is a flowchart showing an example of the flow of the telephone number acquisition process executed by the telephone set 1. The telephone number acquisition processing indicates processing after the telephone set 1 is provided to the user and activated.

  First, the connection destination determination unit 103 checks whether or not the management server telephone number 123 is stored with reference to the storage unit 12 (step S1, hereinafter "step" is omitted). If it is not stored (NO in S1), the connection destination determination unit 103 reads the distribution server telephone number 122 and outputs it to the connection execution unit 104. Subsequently, the connection execution unit 104 accesses the distribution server 2 (S2). Specifically, the connection execution unit 104 controls the communication unit 16 to access the distribution server 2 using the distribution server telephone number 122. At this time, the connection execution unit 104 reads the terminal information 125 from the storage unit 12 and transmits it to the distribution server 2. Subsequently, the connection execution unit 104 acquires the management server telephone number (management server telephone number determined by the distribution server 2 using the terminal information 125) 123 and the next connection time 124 from the distribution server 2 (S3, acquisition step). Then, the connection execution unit 104 stores the acquired management server telephone number 123 and the next connection time 124 in the storage unit 12 (S4, storage step). Then, the telephone number acquisition processing returns to S1.

  On the other hand, when the management server telephone number 123 is stored (YES in S1), the connection destination determination unit 103 reads out the management server telephone number 123 and outputs it to the connection execution unit 104. Subsequently, the connection execution unit 104 refers to the next connection time 124, and stands by until the current time of the place where the management server 3 is installed reaches the time indicated by the next connection time 124 (S5). When the time indicated by the next connection time 124 has come (YES in S5), the connection execution unit 104 accesses the management server 3 (S6, communication step). Specifically, the connection execution unit 104 controls the communication unit 16 and accesses the management server 3 using the management server telephone number 123. Then, the connection execution unit 104 acquires data including the next connection time from the management server 3 (S7). Then, the connection execution unit 104 stores the acquired data in the storage unit 12 (S8). Then, the telephone number acquisition processing returns to S1.

(Flow of initialization process)
Next, with reference to FIG. 7, the flow of the initialization process performed by the telephone 1 will be described. FIG. 7 is a flow chart showing an example of the flow of initialization processing executed by the telephone set 1.

  First, the operation unit 11 stands by for user operation (initialization operation) indicating initialization (S11). When the initialization operation is acquired (YES in S11), the operation unit 11 outputs operation information indicating the content of the initialization operation to the initialization type determination unit 101. Subsequently, the initialization type determination unit 101 determines whether or not the received operation information indicates the first initialization (S12). If it is determined that it indicates the first initialization (YES in S12), the initialization type determination unit 101 outputs a first initialization execution instruction to the initialization execution unit 102. Then, the initialization execution unit 102 executes the first initialization, that is, initialization for deleting at least the management server telephone number 123 and the next connection time 124 (S13, deletion step).

  On the other hand, when it is determined that the received operation information does not indicate the first initialization (NO in S12), the initialization type determination unit 101 outputs a second initialization execution instruction to the initialization execution unit 102. . Then, the initialization execution unit 102 executes the second initialization, that is, initialization that does not delete the management server telephone number 123 and the next connection time 124 (S14). This is the end of the initialization process according to the present embodiment.

Second Embodiment
It will be as follows if other embodiment of this invention is described based on FIGS. 8-11. In the following embodiments, for convenience of explanation, the same reference numerals will be appended to members having the same functions as the members described in the above embodiments, and the description thereof will be omitted.

(Principal configuration of the telephone 4)
First, with reference to FIG. 8, the main configuration of the telephone 4 according to the present embodiment will be described. FIG. 8 is a block diagram showing an example of the main configuration of the telephone 4. Unlike the telephone set 1 described in the first embodiment, the telephone set 4 includes a control unit 40 and a storage unit 42 in place of the control unit 10 and the storage unit 12. Note that the operation unit 11 is omitted in FIG. 8 because the relationship between the operation unit 11 and each member shown in FIG. 8 is thin.

  Unlike the control unit 10, the control unit 40 includes an initialization type determination unit 401 and a connection execution unit 404, instead of the initialization type determination unit 101 and the connection execution unit 104.

  The connection execution unit 404 updates the connection history 421 (communication success / failure history) stored in the storage unit 12 when attempting to connect to the management server 3 in addition to the function of the connection execution unit 104, and indicates that the connection history 421 has been updated. Is notified to the initialization type determination unit 401. Here, the details of the connection history 421 will be described with reference to FIG. FIG. 9 is a view showing a data structure and a specific example of the connection history 421. As shown in FIG. As illustrated in FIG. 9, the connection history 421 includes information indicating the date and time of connection attempt to the management server 3 (information included in the “connection date and time” column) and information indicating whether or not the connection is successful. This is information associated with (information included in the “connection result” column). In the example of FIG. 9, in the information indicating whether the connection is successful, the success is represented by “o” and the failure is represented by “x”, but the present invention is not limited to this example. . Further, the data structure and specific example of the connection history 421 are not limited to the example of FIG.

  Unlike the initialization type determination unit 101, the initialization type determination unit 401 confirms the connection history 421 when receiving a notification from the connection execution unit 404. Then, it is determined whether the connection history 421 satisfies a predetermined condition regarding communication failure. In the present embodiment, in the connection history, it is determined whether or not the connection to the management server 3 once a day has failed five consecutive times (for five consecutive days). The predetermined conditions are not limited to this example. For example, it may be determined whether or not the connection to the latest management server 3 has failed. In the present embodiment, when the connection to the management server 3 fails, the connection on the next day is attempted at the same time as the time of the failed connection, but the present invention is not limited to this example. May be If it is determined that the failure has occurred five consecutive times, the initialization type determination unit 401 outputs a first initialization execution instruction to the initialization execution unit 102. Here, in the example of FIG. 9, failure has occurred five consecutive times in the period of 2015/8/20 to 2015/8/24. In this case, the initialization type determination unit 401 outputs a first initialization execution instruction to the initialization execution unit 102, and the initialization execution unit 102 deletes the management server telephone number 123.

(Flow of initialization process)
Next, the flow of the initialization process performed by the telephone 4 will be described with reference to FIG. FIG. 10 is a flow chart showing an example of the flow of initialization processing executed by the telephone 4. In addition, since the telephone number acquisition process in this embodiment is the same as that of Embodiment 1, description here is abbreviate | omitted.

  First, the initialization type determination unit 401 waits for the update of the connection history 421 (S21). When the connection execution unit 404 is notified of updating of the connection history 421 (YES in S21), the initialization type determination unit 401 confirms the connection history 421, and does the connection to the management server 3 fail five times consecutively? It is determined whether or not it is (S22). If it is determined that failure has occurred five consecutive times (YES in S22), the initialization type determination unit 401 outputs a first initialization execution instruction to the initialization execution unit 102. Then, the initialization execution unit 102 executes the first initialization, that is, initialization for deleting at least the management server telephone number 123 and the next connection time 124 (S23). On the other hand, when it is determined that five consecutive failures have not occurred (NO in S22), the process of S23 is omitted. This is the end of the initialization process according to the present embodiment.

  As described above, when the connection history 421 satisfies a predetermined condition regarding a failure in communication with the management server 3, the telephone 4 according to the present embodiment executes the first initialization to execute the management server. Delete the telephone number 123 and the next connection time 124. If communication between the telephone 4 and the management server 3 fails, there is a high possibility that the management server telephone number 123 is different from the management server telephone number 123 of the management server 3 to which the telephone 4 should access. Therefore, the telephone 4 according to the present embodiment causes the telephone 4 to be once distributed and accessed to the server 2 by automatically deleting the management server telephone number 123 in the above-described case. As a result, since the telephone 4 can acquire again the management server telephone number 123 of the management server 3 to which the telephone 4 should access, the problem that the management server 3 can not be accessed can be automatically solved.

  In the present embodiment, the configuration in which the first initialization is performed when the connection history 421 satisfies a predetermined condition regarding a failure in communication with the management server 3 has been described. However, the telephone 4 according to the present embodiment is configured to delete only the management server telephone number 123 and the next connection time 124 when the connection history 421 satisfies a predetermined condition regarding a failure in communication with the management server 3. It may be

(Modification of Embodiment 2)
Next, a modification of the second embodiment will be described. The above-described telephone set 4 determines whether or not to execute the first initialization with reference to the information in the “connection result” column of the connection history 421. On the other hand, the telephone 4 according to the present modification refers to the information in the “connection date and time” column of the connection history 421 to determine whether or not to execute the first initialization.

  Specifically, when the telephone set 4 is activated, the initialization type determination unit 401 according to the present modification is a record indicating that access to the management server 3 has been tried at the end of the connection history 421 (the connection date and time indicates The record with the newest date and time is confirmed, and it is determined whether or not the period from the date of the record to the present is equal to or longer than a predetermined period. In this modification, the initialization type determination unit 401 determines whether the period is one month or more. Then, if it is one month or more, the initialization type determination unit 401 outputs a first initialization execution instruction to the initialization execution unit 102.

  As described above, when the period from the last communication with the management server 3 to the present is one month or more, the telephone 4 according to the present modification executes the first initialization, and the management server telephone number 123. And delete the next connection time 124. As described above, since the telephone set 4 tries to access the management server 3 once a day if it is used, the telephone set 4 whose duration from the last communication with the management server 3 to the present is one month or more is It has not been used for a long time, in other words, there is a high possibility that the next rental will not be performed after being returned from the rental destination (carrier) to the manufacturer or rental service provider. Such a telephone set 4 executes the first initialization as described above because the carrier to be the next rental destination is likely to change from the previous carrier, and the management server telephone number 123 and the next connection time 124 are set. Automatically delete. Thereby, the operation for executing the first initialization can be omitted.

  In the above-described modification, when the period from the last communication with the management server 3 to the present is one month or more, the telephone set 4 executes the first initialization, but the second initialization That is, initialization that does not delete the management server telephone number 123 and the next connection time 124 may be performed. As a result, after the telephone set 4 is returned from the user to the carrier, the telephone set 4 which has not been used for a long time can be automatically brought into a state where it can be rented (a state where initialization is performed). An operation for executing initialization can be omitted.

(Flow of business initialization process)
Next, with reference to FIG. 11, the flow of the carrier initialization process performed by the telephone 4 will be described. FIG. 11 is a flowchart showing another example of the flow of the carrier initialization process executed by the telephone 4. In addition, since the initialization process according to the present modification is an initialization process when there is a telephone at the maker or the rental service business operator as described above, it is described as a “business operator initialization process”. It distinguishes it from the initialization processing when there are telephones under the user or carrier.

  First, when the telephone set 4 is activated (YES in S31), the initialization type determination unit 401 checks the connection history 421, and determines whether one or more months have passed since the most recent connection (S32). . If it is determined that one month or more has elapsed (YES in S32), the initialization type determination unit 401 outputs a first initialization execution instruction to the initialization execution unit 102. Then, the initialization execution unit 102 executes the first initialization, that is, initialization for deleting at least the management server telephone number 123 and the next connection time 124 (S33). On the other hand, when it is determined that one month or more has not elapsed (NO in S32), the process of S33 is omitted. This is the end of the business operator initialization process according to the present embodiment.

Third Embodiment
Another embodiment of the present invention will be described below with reference to FIGS. 12 and 13. In this embodiment, depending on whether there is a change in the specification information included in the terminal information 125 which may be executed when the telephone set is returned to the maker or the rental service provider, the first initialization or the first The configuration for executing the second initialization will be described.

(Principal configuration of the telephone 5)
First, with reference to FIG. 12, the main configuration of the telephone 5 according to the present embodiment will be described. FIG. 12 is a block diagram showing an example of the main configuration of the telephone 5. Unlike the telephone set 1 described in the first embodiment, the telephone set 5 includes a control unit 50 in place of the control unit 10.

  Unlike the control unit 10, the control unit 50 newly includes a specification information change unit 501. Further, an initialization type determination unit 502 is included instead of the initialization type determination unit 101.

  The specification information changing unit 501 changes the specification information included in the terminal information 125 according to the user operation. Specifically, when the specification information change unit 501 receives the operation information indicating the change of the specification information from the operation unit 11, the specification information change unit 501 reads the terminal information 125 stored in the storage unit 12 and the specification information as indicated by the operation information. Are stored in the storage unit 12. Then, the specification information change unit 501 notifies the initialization type determination unit 502 that the specification information has been changed.

  The initialization type determination unit 502 determines whether to execute the first initialization or the second initialization, according to whether or not the notification that the specification information has been changed is received. Specifically, when the initialization type determination unit 502 receives operation information indicating execution of initialization from the operation unit 11, it receives a notification from the specification information change unit 501 indicating that the specification information has been changed. judge. If the notification has been received, the initialization type determination unit 502 outputs a first initialization execution instruction to the initialization execution unit 102. On the other hand, when the notification has not been received, the initialization type determination unit 502 outputs a second initialization execution instruction to the initialization execution unit 102. Note that when receiving the notification from the specification information changing unit 501, the initialization type determining unit 502 does not receive operation information indicating execution of the initialization from the operation unit 11, and issues a first initialization execution instruction. It may be output to the initialization execution unit 102.

(Flow of business initialization process)
Next, with reference to FIG. 13, the flow of the carrier initialization process performed by the telephone 5 will be described. FIG. 13 is a flowchart showing an example of the flow of the carrier initialization process performed by the telephone set 5. In the same manner as the initialization processing described in the modification of the second embodiment, the initialization processing according to the present embodiment is described as "business operator initialization processing", and the telephone set is used under the user or carrier. There is a distinction between the case of initialization processing.

  First, the operation unit 11 stands by for user operation (initialization operation) indicating initialization (S41). When the initialization operation is acquired (YES in S41), the operation unit 11 outputs operation information indicating the initialization operation to the initialization type determination unit 502. Subsequently, the initialization type determination unit 502 determines whether the specification information has been updated (S42). Specifically, the initialization type determination unit 502 determines whether or not a notification indicating that the specification information has been changed from the specification information change unit 501 has been received. If it is determined that the specification information is updated (YES in S42), the initialization type determination unit 502 outputs a first initialization execution instruction to the initialization execution unit 102. Then, the initialization execution unit 102 executes the first initialization, that is, initialization for deleting at least the management server telephone number 123 and the next connection time 124 (S43).

  On the other hand, when it is determined that the specification information is not updated (NO in S42), the initialization type determination unit 502 outputs a second initialization execution instruction to the initialization execution unit 102. Then, the initialization execution unit 102 executes the second initialization, that is, initialization that does not delete the management server telephone number 123 and the next connection time 124 (S14). This is the end of the initialization process according to the present embodiment.

  As described above, the telephone set 5 according to the present embodiment determines whether or not the management server 3 to which the telephone set 5 should access next is changed based on the presence or absence of the change of the specification information. Delete the telephone number 123 and the next connection time 124. As a result, the maker or the rental service provider does not have to confirm whether to delete the management server telephone number 123 and the next connection time 124 at each telephone set 5 or not. In addition, since the telephone server 5 which does not need to delete the management server telephone number 123 and the next connection time 124 does not delete these pieces of information, when the telephone 5 is provided to the user, it is necessary to access the distribution server 2 once. It disappears.
