Description

  The present invention relates to mobile communication technology, and more particularly to automatic setting of an incoming mode in a mobile terminal.

  While mobile terminals such as mobile phones and PHS have convenience that can be used anywhere and anytime, considerations according to the situation are necessary when using public transportation. There are multiple types of mobile terminal reception modes such as normal reception mode, vibration reception mode, automatic message transmission mode, no response mode, etc., so that the user can set one of the reception modes according to the situation. It has become. The current incoming mode setting of the mobile terminal is performed by a user's manual operation such as pressing an incoming mode setting button. For this reason, when using public transportation, the user must change the incoming call mode by operating a button each time he gets on and off, and set / cancel the incoming call mode. If the user forgets to operate the button or the user does not set the appropriate incoming call mode due to lack of public manners, the incoming sound will cause discomfort to the surroundings.

  As an example of a public transportation vehicle, consider the case where a user is on a bus. At this time, the user can set an incoming mode that is generally referred to as a manner mode, in consideration of the surroundings (incoming call notification with silence by vibration or LED blinking). At this time, when there is an incoming call, the user notices the incoming call by vibration or LED blinking, but it is considered that the user does not respond because the user is on the bus. In the current mobile communication system, in such a situation, the user of the mobile terminal on the transmission side is notified of the situation of the user of the mobile terminal on the reception side (noticing the incoming call but unable to answer while on the bus) There is no way to tell. A user on the outgoing side who does not know the reason for not answering repeatedly feels stressed by not making a response by repeating the outgoing operation.

  As a technique related to automatic setting of the incoming mode of a mobile terminal, there is one described in Patent Document 1. Patent Document 1 aims to allow a mobile terminal itself to recognize a current position and automatically switch to a communication mode suitable for the current position. The mobile terminal includes a GPS device and map information, recognizes the current position based on the GPS and map information, and automatically switches the incoming mode according to the recognized current position. More specifically, map information is acquired in advance, and the incoming mode switching point and the incoming mode after switching are registered for the acquired map information. Then, the current position information is acquired by GPS when a call is received, and the acquired position information is compared with a switching point on the registered map information, and automatic switching to the registered reception mode is performed according to the comparison result. carry out.

  The above-mentioned Patent Document 1 is for determining the incoming mode at a mobile terminal, and map information needs to be stored in the mobile terminal. In addition, it is necessary to register the incoming mode switching point and the incoming mode in advance.

JP 2002-314642 A

  In the case of the method of automatically switching the incoming call mode based on the information of the switching points registered in advance, if the route is always used, such as commuting, commuting route, etc., once it is registered, it will be automatically received every day The mode is automatically changed for convenience. However, if you use a different route than usual, or if you use a local transportation other than the acquired map, before you go out, you will need to register a new switching point and incoming call mode for all transportation points. You must change the incoming mode manually each time you get on and off without going out or registering.

  The invention of the present application can automatically determine that the user of the mobile terminal is using public transportation without the need for pre-registration, and can automatically set the incoming mode based on the determination result. The purpose is to be able to. In addition, if it is determined that the user of the mobile terminal on the receiving side is using public transportation, the user of the mobile terminal on the outgoing side is notified that the user on the receiving side is using public transportation. The purpose is to be able to notify.

In order to solve the above-described problems, the present invention provides a plurality of wireless base stations that communicate wirelessly with a plurality of mobile terminals present in a cover area and a plurality of vehicles having a communication function, and an operation system that manages the operation of the vehicle.

Here, the mobile terminal managed by the radio base station 30a is a plurality of mobile terminals within the coverage area of the base station, and the mobile terminal 50a will be described as an example.
The radio base station 30a transmits a position information request signal to the bus operation management server 20 (S601). The radio base station transmits a position information acquisition request signal periodically (for example, at intervals of 3 seconds) to the bus operation management server and the mobile terminal. This position information request signal includes designated time information. The bus operation management server 20 grasps the coverage area of each radio base station, and from the information stored in the bus location information table described in FIG. 4, the radio base station that has transmitted the location information request signal. Search for position information that has position information in the cover area and that matches the specified time. If there are a plurality of pieces of position information as a result of the search, all of the plurality of pieces of position information are returned (S602).

  The radio base station 30a also transmits a position information request signal to the mobile terminal 50a in the cover area in parallel with the position information request to the bus operation management server 20 (S603). The location information request signal transmitted to the mobile terminal 50a also includes specified item information. The mobile terminal 50a operates the GPS unit 503 in accordance with the specified time and receives a signal from the GPS satellite 10. The location information is acquired, and the contents of the terminal location information table described with reference to FIG. 5 are updated. Further, the acquired position information is returned to the radio base station 30a (S604). At this time, the positional information consistency is obtained by including the same designated time information in the positional information request signal transmitted to the bus operation management server 20 and the positional information request signal transmitted to the mobile terminal 50a. In addition, the radio base station 30a periodically repeats a sequence for acquiring position information, and holds information for several past times.

  The radio base station 30a that has acquired the location information from the bus operation management server 20 and the mobile terminal 50a stores the location information in the location information management table 3161 of the memory 316 under the management of the location information management unit 315. .

A position information table managed by the radio base station will be described.
FIG. 7 is a diagram illustrating a configuration example of a position information table provided in the radio base station.
The position information stored in the position information table includes time information that is the time when the position information from the bus operation management server 20 and the mobile terminal 50a is acquired, classification information that indicates the classification of the individual that acquired the position information, Identification number information for specifying, latitude information for storing the acquired latitude information, longitude information for storing the acquired longitude information, and speed information are stored in association with each other. The speed information is obtained for the individual with the same identification number by taking the difference of the latitude / longitude information of the previous information and obtaining the moving distance, and the moving speed is calculated from the time difference from the previous information and the obtained moving distance. Calculated and memorized. The classification information is information indicating whether the individual that acquired the position information is a bus or a mobile terminal, but may be omitted if it can be determined from the identification number.
These pieces of position information may be sorted by time and collected for each piece of the same time information.

Subsequently, the sequence in which the location information management unit 315 of the radio base station 30a creates the terminal status management table from the information of the location information management table shown in FIG. 7 under the control of the base station control unit 305 is shown in FIG. This will be described with reference to FIG.
FIG. 8 is a diagram illustrating a configuration example of a terminal status management table provided in the radio base station.
In the terminal status management table, an individual identification number and a bus flag which is a determination result of whether or not the user is on the bus are stored in association with each other.

A procedure for creating the terminal status management table will be described with reference to FIG.
FIG. 9 is a flowchart illustrating a procedure for creating a terminal status management table.
This flow is started after the location information requested by the radio base station 30a from the bus operation management server 20 and the mobile terminal 50a is transmitted to the radio base station 30a (after S602 and S604 in FIG. 6). The position information is determined.
First, information is read from the position information table described with reference to FIG. 7 (S901). It is determined whether the classification information is “mobile” (S902). If the classification information is “mobile”, whether there is a bus having the same position information at the same time as the time indicated by the acquired information. The table is searched (S903). If there is a bus having the same position information at the same time, it is next determined whether or not the speed of the acquired “mobile” information is the same as that of the bus (S904). If the speed of the acquired “mobile” information and the speed of the bus are the same, it is determined that the user of the “mobile” is on the bus (bus flag 1) (S905). If there is no bus with the same position information at the time indicated by the acquired information in S903, and there is a bus with the same position information in S904, but the moving speed is not the same as that bus, use of the “mobile” It is determined that the person is not on the bus (bus flag 0) (S906). And an identification number and a bus flag are matched and memorize | stored in a terminal status management table (S907).

Next, an operation example when there is an incoming call to the mobile terminal 50a on the bus will be described with reference to FIG.
FIG. 10 is a sequence diagram showing a telephone connection operation in one embodiment of the present invention.
Note that the forced manner mode setting used in the following description means that even if the mobile terminal 50a is set to an incoming call mode for outputting a ringtone, for example, a sound (ringtone or ringtone) is forcibly controlled by the control from the radio base station 30a. This means that the mode is set in which the user of the mobile terminal 50a is notified of an incoming call by vibration or LED without sounding a button confirmation sound.

  In the description of FIG. 10, the transmission terminal is described as a mobile terminal according to the system configuration diagram of FIG. 1, but the same operation is possible when the transmission terminal is a fixed telephone.

In FIG. 10, when the radio base station 30a receives a telephone connection request signal (S1001) from the transmitting terminal 50c to the receiving terminal 50a, the incoming mode determination unit 313 searches the terminal status management table 3162 and sets the bus flag of the receiving terminal 50a. Confirm (S1002). In this example, the bus flag of the receiving terminal 50a is set to “1”, indicating that the receiving terminal 50a is on the bus.
The radio base station 30a determines from the bus flag that the user of the receiving terminal 50a is on the bus and operates the message return unit 312. The message return unit 312 returns a voice message to the calling terminal 50c (“You cannot answer the phone because it is currently in public transportation”) (S1003), and the receiving terminal 50a is on the bus. In addition, the receiving terminal 50a is instructed to receive in the forced manner mode (S1004), and information notifying that the voice message is being returned is transmitted to the transmitting terminal (S1005).

  The receiving terminal 50a receives the forced manner mode reception instruction in the incoming unit 502, and operates the vibrating unit 508 and the LED 509 without sounding regardless of the type of incoming mode currently set by the user. An incoming call notification is made to the user of the receiving terminal 50a. Thereafter, when the calling terminal 50c interrupts the telephone connection request (S1006), the radio base station 30a transmits a telephone connection request interruption signal to the receiving terminal 50a (S1007).

  10, since the content of the voice message that the wireless base station 30a is returning to the transmitting terminal 50c is displayed on the display unit 510 of the receiving terminal 50a, the user of the receiving terminal 50a who notices the incoming call It can be recognized that a voice message is being returned to the user of the transmission terminal 50c. If the user of the receiving terminal 50a presses the incoming call button on the input unit 506 while the voice message is being returned, a call can be made between the calling terminal 50c and the receiving terminal 50a, and the voice message is automatically disconnected accordingly. . An example of this operation will be described with reference to FIG.

FIG. 11 is a sequence diagram showing another example of the telephone connection operation in the embodiment of the present invention.
In FIG. 11, S1001 to S1005 are the same as the description of FIG. In the example of FIG. 11, the user of the receiving terminal 50a that has recognized this incoming call notification transmits a call permission signal from the input unit 506 (S1008). Receiving this, the radio base station 30a stops the voice message being transmitted to the transmission terminal 50c (S1009), and the line between the transmission terminal 50c and the reception terminal 50a is connected. It is possible to make a phone call.

  In the above, an example has been described in which it is determined whether or not the user is on the bus by matching the acquisition times of the location information of the bus and the mobile terminal and matching the speed information. In addition to this example, even when the radio base station requests location information without specifying a time and acquires the location information of the bus and the mobile terminal, both the location information and the speed information are errors below a predetermined value, and It may be determined that the mobile terminal is on the bus on the condition that the continuation is continued twice or more.

In the first embodiment, the operation example when the telephone connection request is made when the receiving terminal 50a is on the bus has been described, but the embodiment when the mail is distributed will be described with reference to FIG.
FIG. 12 is a sequence diagram showing the mail delivery operation in one embodiment of the present invention.
Receiving the mail delivery request signal from the transmitting terminal 50c to the receiving terminal 50a (S1201), the incoming mode determination unit 323 of the radio base station 30a refers to the terminal status management table and confirms the bus flag set in the receiving terminal 50a. (S1202). In this example, since the bus flag of the receiving terminal 50a is “1”, the radio base station 30a instructs the receiving terminal 50a to set the forced manner mode (S1203). Further, mail delivery is performed (S1204).

  The receiving unit 502 of the receiving terminal 50a receives the forced manner mode instruction and operates the vibration unit 508 and the LED 509 regardless of the type of the currently set incoming mode, thereby sending a mail to the user of the receiving terminal 50a. Perform incoming call notification.

13 and 14 are diagrams for explaining another configuration example of the mobile communication system to which the present invention is applied.
FIG. 14 is a block diagram for explaining the configuration of the radio base station 90 in the system configuration shown in FIG.

  In the example shown in FIG. 13, the mobile communication system includes a plurality of mobile terminals 50a, 50b, 50c..., A plurality of buses 80 (only one is shown in FIG. 13), a plurality of mobile terminals 50, and It comprises a plurality of radio base stations 90 that transmit and receive signals wirelessly with the bus 80. In the mobile communication system shown in FIG. 13, the configuration provided in the bus operation management server in the mobile communication system shown in FIG. 1 is distributed to each radio base station.

FIG. 14 is a block diagram illustrating a configuration of a radio base station in the mobile communication system shown in FIG.
The radio base station 90 shown in FIG. 14 includes a numbering system table 3264 for registering the numbering system of identification numbers in the memory unit 316 of the wireless base station 30 shown in FIG.

  Also in the embodiment of the mobile communication system shown in FIG. 13, the mobile terminal 50 a acquires the position information by operating the GPS unit 503 and receiving a signal from the GPS satellite 10 as in the first embodiment. Then, the position information of the mobile terminal 50 a is stored in the position information notification unit 504 and the position information notification unit 504 transmits the acquired position information to the radio base station 90. The bus 80 also has a GPS function, and transmits the acquired position information to the radio base station 90.

  In the first embodiment, the radio base station acquires the bus position information from the bus operation management server. However, in FIG. 13, the radio base station acquires the position information directly from the bus 80. As a result, the system configuration becomes simpler. Here, in the first embodiment, since the bus position information is acquired from the bus operation management server 20, the classification information stored in the position information table of the radio base station 30 has the position information from the bus operation management server 20. Since it can be seen whether it is sent or sent from the mobile terminal 50, it can be uniquely determined. However, in the configuration of FIG. 13, the mobile terminal 50 and the GPS function-equipped bus 80 are not distinguished from each other, and thus classification information cannot be set.

  In order to solve this problem, the number system of the identification number assigned to the bus 80 and the terminal number assigned to the mobile terminal 50a is determined in advance, and a number is assigned to each individual accordingly. The numbering system table 3264 is registered in advance in the memory 326 of the radio base station 90. As a specific example of the number system, for example, the first digit of the number of the mobile terminal 50a is “0”, and the first digit of the identification number of the GPS function-equipped bus 80 is “1”.

  To explain the sequence in FIG. 6 again, the radio base station 90 transmits a location information request signal including information on the designated time to the mobile terminal 50 and the bus 80 in the cover area (S603). The mobile terminal 50 and the bus 80 acquire position information by operating the GPS unit 503 at a specified time and receiving a signal from the GPS satellite 10. Also, the terminal location information in the terminal location information table at the designated time is returned (S604). The radio base station 90 that has acquired the position information determines the classification from the first digit of the identification number and sets the classification information. The subsequent sequence is the same as that described in the first embodiment, and it is possible to automatically determine whether or not the user is on the bus, and the forced manner mode can be set.

  FIG. 15 is a system configuration diagram when the bus operation management server 20 is eliminated from the system configuration diagram of FIG. 1.

A bus operation system 60 managed by a bus company manages and supervises position information of all buses managed by the bus company. The radio base station 30 is connected to the bus operation system 60 via the network 70, selects the position information of the bus that is traveling in its own cover area from the bus operation system 60, and holds it. This eliminates the bus operation management server 20 from the system configuration diagram of FIG. 1 and enables the system configuration of FIG. 15 that can simplify the system.
In the configuration illustrated in FIG. 15, the configurations, flowcharts, and sequences of the radio base station and the mobile terminal are the same as those in the first embodiment.
