Description

  The present invention relates to a communication system and a position information providing system that acquire position registration area information and position information of a mobile communication terminal accommodated in a moving body based on information from a device that manages the operation of the moving body.

  As is well known, in a mobile communication service, the position management device generally stores the position of each mobile communication terminal so that a mobile communication terminal such as a mobile phone can be received anywhere. When an incoming call request is generated in a certain mobile communication terminal, first, the location registration area to which the target mobile communication terminal belongs is specified by referring to the stored contents of the location management device. Next, the location management device generates a call request and transmits it to the destination mobile communication terminal via the exchange station belonging to the corresponding location registration area and each base station.

  In order to register the location registration area in the location management device described above, the mobile communication terminal receives location registration area information broadcast from the base station, and identifies the received location registration area information and the mobile communication terminal A pair with the identification number is transmitted to the location management apparatus via the base station and the exchange.

As a method of such position registration, for mobile communication terminals accommodated in a moving body such as a train, a technique for representing a position registration request by a plurality of mobile communication terminals in a train by a communication device installed in the train Is known (see Patent Document 1).

  Embodiments of the present invention will be described below with reference to the drawings. Such an embodiment shows one aspect of the present invention, and does not limit the present invention, and can be arbitrarily changed within the scope of the present invention.

<1. First Embodiment>
<1-1: Configuration of First Embodiment>
<1-1-1: Overall Configuration of Communication System>
FIG. 1 is a diagram showing an overall configuration of a communication system according to an embodiment of the present invention. As shown in the figure, this communication system includes a mobile communication network NET, a mobile body 2, and an operation management device 30.

  As the moving body 2, transportation such as a train or a bus is applicable, but in this example, it is assumed to be a train. Further, in FIG. 1, only one moving body 2 is illustrated, but actually, a larger number of moving bodies 2 exist. The operation management device 30 manages the operation status of each mobile unit 2, generates the current position of the mobile unit 2, the operation plan, the track / road status, etc. as operation information INFx and provides it.

  The operation information INFx includes moving body position information INF1 indicating the position of the moving body 2 and related position information INF2 related to the operation of the moving body 2. The moving body position information INF1 is given in the form of latitude and longitude of the moving body 2, or in the form of a route name, distance from the nearest station, and traveling direction. For example, “136 degrees East longitude, 36 degrees North latitude”, “Tokaido line, 2 km from Shinagawa to Yokohama” and so on. Further, the related position information INF2 is information related to train operation, and includes a train name (for example, Hikari No. 10), information on accidents and disasters, and the like.

  The mobile communication network NET includes a plurality of base stations 3-1, 3-2,..., A plurality of switching stations 4-1, 4-2,. I have. Among these, the mobile terminal location management device 50A collectively manages location registration area information of each mobile communication terminal.

  Each base station 3-1, 3-2,... Is arranged at a predetermined interval, and each base station area 4 (indicated by reference numerals “4a” to “4f” in FIG. 1). Form. Each base station area 4 is an area in which wireless communication with the base station 3 forming the base station area 4 is possible. In the following, it is assumed that base stations 3-1 to 3-6 form base station areas 4a to 4f, respectively, as shown in FIG. A location registration area 5 (indicated by reference numerals “5A” and “5B” in FIG. 1) is a collection of a plurality of base station areas 4, and each of the exchanges 4-1, 4-2. Are provided corresponding to.

  The moving body 2 is a train moving on the track L, and a plurality of passengers having mobile communication terminals 1-1, 1-2,. The moving body 2 sequentially passes through a plurality of position registration areas 5 traversed by the track L. In addition, a notification device BC is installed in the moving body 2. The notification device BC wirelessly notifies the mobile unit identification number IDt. The mobile object identification number IDt is an identifier uniquely assigned so that each mobile object 2 can be identified. Each mobile communication terminal 1 is uniquely assigned a terminal identification number IDm for identifying each terminal, and each mobile communication terminal 1 stores each terminal identification number IDm in advance. For example, a telephone number corresponds to the terminal identification number IDm.

When each mobile communication terminal 1 is not accommodated in the mobile body 2, it receives the position registration area information INF notified from the base station 3 and stores it. When the location registration area is changed, each mobile communication terminal 1 notifies the mobile communication network NET of a set of location registration area information INF and terminal identification number IDm.
On the other hand, when each mobile communication terminal 1 is accommodated in the mobile body 2, each mobile communication terminal 1 receives the mobile body identification number IDt notified from the notification device BC, and receives the mobile body identification number IDt and the terminal identification number IDm. To the mobile communication network NET.

  More specifically, the mobile communication terminal 1 always monitors whether or not the mobile body identification number IDt has been notified, and performs the operation of notifying the mobile body identification number IDt only when receiving the mobile body identification number IDt. While receiving the identification number IDt, the location registration area information INF is not notified even if the location registration area is changed. That is, when the mobile communication terminal 1 does not receive the mobile unit identification number IDt from the notification device BC and the location registration area is changed, the mobile communication terminal 1 sets the set of the location registration area information INF and the terminal identification number IDm to the mobile communication network NET. Sending. Thereby, it is possible to save radio resources between the base station 3 and the mobile communication terminal 1 and to reduce traffic.

<1-1-2: Configuration of Mobile Terminal Location Management Device 50A>
Next, FIG. 2 is a block diagram showing a configuration of the mobile terminal location management device 50A. As shown in this figure, the mobile terminal location management device 50A includes a control device 51 and a location table TBL.

  The mobile terminal location management device 50A has a function of managing to which location registration area each mobile communication terminal 1 belongs or to which mobile unit 2. Secondly, the mobile terminal location management device 50A has a function of generating a call request when there is an incoming call request to a certain mobile communication terminal 1.

  In order to realize the first function, the position table TBL is used in the present embodiment. FIG. 3 is an explanatory diagram showing the stored contents of the position table TBL. The location table TBL includes a plurality of records Rb1, Rb2,..., And one record stores the terminal identification number IDm of each mobile communication terminal 1 and the location registration area information INF in association with each other. However, when a certain mobile communication terminal 1 is accommodated in the mobile body 2, the mobile body identification number IDt of the mobile body 2 is stored instead of the location registration area information INF.

  Here, the location registration area information INF is information indicating a location registration area where the mobile communication terminal 1 is located. The mobile communication terminal 1 communicates with the base station 3 using the control channel, recognizes the location registration area information INF where the mobile station 1 is located, and transmits the mobile terminal via the base station 3 and the exchange 4 together with the terminal identification number IDm. The position management device 50A is notified. Further, when the mobile communication terminal 1 is accommodated in the mobile body 2, the mobile body identification number IDt is acquired and the set of the mobile body identification number IDt and the terminal identification number IDm is moved via the base station 3 and the exchange 4. The terminal location management device 50A is notified. Based on this notification, the control device 51 updates the stored contents of the position table TBL.

  For example, the mobile communication terminal 1-1 is accommodated in the mobile body 2, the terminal identification number IDm assigned to them is “X00001”, and the notification device BC notifies the mobile body identification number IDt “A01234”. If present, the position table TBL stores the terminal identification number IDm “X00001” and the mobile body identification number IDt “A01234” of the mobile communication terminal 1-1 in association with the record Rb1, as shown in FIG.

  Next, the control device 51 is connected to the position table TBL, reads / writes data from / to these, and communicates with the mobile position management device 40A and the exchange 4.

<1-1-3: Configuration of Moving Body Position Management Device 40A>
Next, FIG. 4 is a block diagram showing the configuration of the mobile object location management device 40A. As shown in this figure, the mobile object position management device 40A includes a control unit 41 and a conversion unit 42.

  First, the control unit 41 is connected to the conversion unit 42 and functions as a control center that controls the entire device, and performs data communication between the operation management device 30 and the mobile terminal location management device 50A.

  Next, the conversion part 42 produces | generates the location registration area information INF based on the mobile body location information INF1 of the operation information INFx notified from the operation management apparatus 30. FIG. The moving body position information INF1 is given in the form of the latitude and longitude of the moving body 2 as described above, or is given in the form of the route name, the distance from the nearest station, and the traveling direction. Even if the information INF1 is given, it can be converted into the location registration area information INF.

  The conversion unit 42 includes, for example, a first table that stores latitude / longitude and location registration area information INF in association with each other, and a second table that stores route map and location registration area information INF in association with each other. Then, when the moving body position information INF1 is given in the form of latitude and longitude, the conversion unit 42 refers to the first table and converts the moving body position information INF1 into position registration area information INF, while the moving body position information INF1 is When given in the form of route name, distance from the nearest station, and direction of travel, the position of the moving body 2 on the route map is specified with reference to the second table, and the position registration area information INF corresponding to the position is obtained. Output.

<1-2. Operation of First Embodiment>
Next, the operation of the communication system will be described with reference to the drawings. In this example, it is assumed that the mobile communication terminal 1 is accommodated in the mobile body 2 and an incoming call request is issued to the mobile communication terminal 1.

  FIG. 5 is a sequence diagram showing the operation of the communication system. When the mobile communication terminal 1 is accommodated in the mobile body 2, the mobile communication terminal 1 receives the mobile body identification number IDt notified from the notification device BC (step S1), and the mobile body identification number IDt and the terminal identification number IDm are received. A location registration notification including the set is transmitted to the mobile terminal location management device 50A via the base station 3 (not shown) and the exchange 4 (step S2). The mobile terminal location management device 50A updates the stored contents of the location table TBL based on the location registration notification (step S3).

  For example, if the terminal identification number IDm of the mobile communication terminal 1 is “X00002” and the mobile body identification number IDt of the mobile body 2 is “A01234”, the updated position table TBL includes As shown in the record Rb2, “X00002” and “A01234” are recorded in association with each other.

  By the way, when there is a change in the location registration area, the mobile communication terminal 1 normally notifies the mobile terminal location management device 50A of the changed location registration area information, but the mobile unit notified from the notification device BC. This notification is stopped during the period in which the identification number IDt is received. This is because the location registration area information is acquired based on the operation information INF1 from the operation management device 30 during the period in which the mobile communication terminal 1 is accommodated in the mobile body 2. Thereby, since the notification accompanying the change of the location registration area can be eliminated, the communication resources of the mobile communication network NET can be saved.

  Now, assuming that an incoming request for the mobile communication terminal 1 is generated in the switching center 4, the switching center 4 notifies the mobile terminal location management device 50A of an area information inquiry request REQ1 (step S4). This area information inquiry request REQ1 includes the terminal identification number IDm of the mobile communication terminal 1.

  Next, when the mobile terminal location management device 50A receives the area information inquiry request REQ1, the control device 51 searches the location table TBL based on the terminal identification number IDm included in the area information inquiry request REQ1 (step S5). . The control device 51 determines whether the information read from the position table TBL is the position registration area information INF or the moving body identification number IDt. The exchange 4 is notified as an information inquiry response. In this example, since the mobile communication terminal 1 is accommodated in the mobile body 2, the mobile body identification number IDt is read from the position table TBL. In this case, processing is performed as follows.

  The mobile terminal location management device 50A generates an area information inquiry request REQ2 including the mobile unit identification number IDt, and notifies this to the mobile unit location management device 40A (step S6). Thereafter, the mobile body position management device 40A generates an operation information inquiry request REQ3 including the mobile body identification number IDt, and notifies this to the operation management device 30 (step S7).

  Thereafter, the operation management device 30 converts the moving body identification number IDt into an identification number used inside the operation management device 30, and generates operation information INFx based on this. Then, the operation management device 30 notifies the operation information inquiry response RES3 including the moving object identification number IDt and the operation information INFx to the moving object position management device 40A (step S8).

  Next, the mobile body location management device 40A converts the mobile body location information INF1 included in the operation information INFx into location registration area information INF (step S9), and an area including the location registration area information INF and the mobile body identification number IDt. An information inquiry response RES2 is notified to the mobile terminal location management device 50A.

  Next, the mobile terminal location management device 50A that has received the area information inquiry response RES2 notifies this to the exchange 4 as an area information inquiry response RES1 (step S10). Thereafter, the exchange 4 notifies the base station 4 belonging to the location registration area indicated by the location registration area information INF of a call request including the mobile unit identification number IDt, and waits for a response from the mobile communication terminal 1 to connect. Process.

According to the first embodiment described above, when the mobile communication terminal 1 is accommodated in the mobile body 2, the mobile communication terminal 1 transmits the location registration area information INF to the mobile communication network even if the location registration area is changed. Since there is no need to notify the NET, radio resources can be saved, and traffic of the base station 3 and the switching center 4 can be reduced.
Further, unlike the prior art, it is not necessary to provide a communication device having a location registration function in the moving body 2, so that the configuration can be simplified.
Furthermore, since the operation information INFx is converted into the location registration area information INFx used in the mobile communication network NET, the location registration area of each mobile communication terminal 1 can be managed using this.

<2. Second Embodiment>
<2-1: Configuration of Second Embodiment>
The communication system according to the second embodiment of the present invention is the same as the communication system of the first embodiment shown in FIG. 1 except that the mobile terminal location management device 50B is used instead of the mobile terminal location management device 50A. .

  FIG. 6 is a block diagram showing the configuration of the mobile terminal location management device 50B. As shown in this figure, the mobile terminal location management device 50B includes a control device 51, a first location table TBL1, and a second location table TBL2. Here, the second position table TBL2 is the same as the position table TBL of the first embodiment described above. That is, the mobile terminal location management device 50B is different from the mobile terminal location management device 50A of the first embodiment in that it includes the first location table TBL1.

  The mobile terminal location management device 50B has a function of managing which location registration area each mobile communication terminal 1 belongs to. In particular, for the mobile communication terminals 1 accommodated in the mobile body 2 such as a train, the location registration area is managed by grouping each mobile body 2 as a key. For this purpose, in the present embodiment, a hierarchized first position table TBL1 and second position table TBL2 are used.

  FIG. 7 is an explanatory diagram showing the contents stored in the first and second position tables. The first position table TBL1 includes a plurality of records Ra1, Ra2,..., And stores a moving body identification number IDt assigned to the moving body 2 and position registration area information INF in association with each other. The total number of records matches the total number of mobile units 2. Therefore, by referring to the first position table TBL1, it is possible to know which position registration area a certain mobile unit 2 belongs to.

  For example, if the moving body 2 is located in the position registration area 5A and the moving body identification number IDt assigned to the moving body 2 is “A01234”, the first position table TBL1 includes As shown in FIG. 4, the mobile object identification number IDt “A01234” and the location registration area “5A” are stored in association with the record Ra1.

  In the present embodiment, when there is a change in the operation information INFx of the mobile body 2, the operation management device 30 notifies the mobile body position management device 40A of this, and the mobile body position management device 40A positions the operation information INFx. It is converted into registered area information INF and notified to the mobile terminal location management device 50B. Thereby, the mobile terminal location management device 50B updates the stored contents of the first location table TBL1. Note that the contents stored in the second position table TBL2 are updated by notification from the mobile communication terminal 1, as described in the first embodiment.

  Here, it is assumed that the storage contents of the first and second location tables TBL1, TBL2 are as shown in FIG. 7, and the terminal identification number IDm of a certain mobile communication terminal 1 is “X00001”. In this case, in order to know the location registration area information INF of the mobile communication terminal 1, first, the second location table TBL2 is searched using the terminal identification number IDm “X00001” as a key, and the mobile body identification number IDt “A01234” is obtained. obtain. Next, the first location table TBL1 is searched using the mobile unit identification number IDt “A01234” as a key, and location registration area information INF “5A” is obtained.

<2-2: Operation of Second Embodiment>
Next, the operation of the communication system according to the second embodiment will be described with reference to the sequence diagram shown in FIG.
First, the operation from when the mobile communication terminal 1 is accommodated in the mobile body 2 until the mobile terminal location management device 50B updates the stored contents of the second location table TBL2 based on the location registration notification is the first implementation. It is the same as the form (steps S1 to S3).

  Next, when the operation status of the mobile body 2 changes in the operation management device 30, the operation management device 30 notifies the operation status change notification N1 to the mobile body position management device 40A (step S21). The operation status change notification N1 includes the moving body identification number IDt of the moving body 2 and the operation information INFx.

  Thereafter, the moving body position management device 40A converts the moving body position information INF1 included in the operation information INFXx into position registration area information INF (step S22), and includes the position registration area information INF and the moving body identification number IDt. The area information change notification N2 is generated and notified to the mobile terminal location management device 50B (step S23).

  For example, it is assumed that the moving body 2 is a train on the Tokaido Line, is proceeding from Shinagawa Station toward Yokohama, and arrives at Yokohama Station after a predetermined time. Moreover, Shinagawa station belongs to the location registration area 5A, and Yokohama station shall belong to the location registration area 5B. And the operation management apparatus 30 shall generate | occur | produce the information "it is stopping at Yokohama station" as mobile body position information INF1 when it arrives at Yokohama station. In this case, when the moving body position management device 40A receives the operation status change notification N1 including the moving body position information INF1, the control unit 41 uses the conversion unit 42 to indicate the moving body position information INF1 in the position registration area 5B. This is converted into location registration area information INF, and this is notified to the mobile terminal location management device 50B.

  Next, when the mobile terminal location management device 50B receives the area information change notification N2, the first location table TBL1 is searched based on the mobile unit identification number IDt included therein, and the location registration area information INF is overwritten (step) S24). Thereby, the stored contents of the first position table TBL1 always reflect the latest operation status. In the above-described example, if the mobile object identification number IDt is “A01234” and the stored content before update is as shown in FIG. 7, the location registration area information INF included in the record Ra1 is changed from “5A” to “ 5B ".

  According to the second embodiment, for example, when the operation state changes due to movement of the moving body 2, the operation management device 30 detects this and autonomously generates operation information INFx to move. This is notified to the body position management device 40A. The operation information INFx is converted into location registration area information INF and stored in the first location table TBL1 of the mobile terminal location management device 50B. Therefore, the moving body identification number IDt and the position registration area information INF stored in the first position table TBL1 are always in the latest state. Thereby, even if the mobile communication terminal 1 accommodated in the mobile body 2 has an incoming call request, there is no need to inquire about the operation status to the operation management device 30. Therefore, this communication system ends the incoming call processing in a short time. There is an advantage that can be.

Information is transmitted to the location information server 60 via the wireless transmission / reception unit 120.

<3-2. Operation of Third Embodiment>
Next, the operation of the location information providing service by the location information providing system will be described with reference to the drawings. FIG. 12 is a sequence diagram showing the operation of the position information providing system according to the third embodiment.

  When a user wants to receive a location information service for a certain mobile communication terminal 1, the client terminal 70 is operated to access the location information server 60, and the terminal identification number IDm ( For example, telephone number). Then, the client terminal 70 transmits the mobile terminal location information request REQ4 including the terminal identification number IDm to the location information server 60 (step S31).

  When receiving the mobile terminal location information request REQ4, the location information server 60 transmits a mobile terminal inquiry request REQ5 to the mobile terminal location management device 50 (step S32). This mobile terminal inquiry request REQ5 includes a terminal identification number IDm.

  Next, the mobile terminal location management device 50B searches the first and second location tables TBL1 and TBL2 to obtain location registration area information INF corresponding to the terminal identification number IDm (step S33). Further, the mobile terminal location management device 50 determines whether or not the mobile unit identification number IDt is stored in the location registration area information column of the second location table TBL2, and if it is stored, it is “1”. If it is not stored, a boarding flag FRG that is “0” is generated (step S33).

  Thereafter, the mobile terminal location management device 50 transmits the mobile terminal inquiry response RES5 including the location registration area information INF and the boarding flag FRG to the location information server 60 (step S34). The location information server 60 that has received the mobile terminal inquiry response RES5 executes the calling application based on the location registration area information INF and calls the mobile communication terminal 1 (step S35). Specifically, the terminal identification number IDm is notified to the base station 3 belonging to the location registration area indicated by the location registration area information INF via the exchange 4 and called. Further, the position information server 60 generates the boarding information indicating that the boarding is in progress when the boarding flag FRG is “1”, but does not generate the boarding information when the boarding flag FRG is “0”.

  The mobile communication terminal 1 that has received the mobile terminal call generates position information indicating the current position, and related information indicating the moving direction and moving speed, and transmits a mobile terminal response including these information to the position information server 60 ( Step S36).

  The location information server 60 that has received the mobile terminal response transmits a location information response RES4 including location information, related information, and boarding information to the client terminal 70 (step S37). For example, when the user carries the mobile communication terminal 1 and is on the train, the train is located at 138 degrees east longitude and 36 degrees latitude, and is traveling south at a speed of 46 km, the client terminal 70 Position information indicating "138 degrees east longitude and 36 degrees latitude", related information indicating "movement speed 46 km, traveling direction south", and boarding information indicating "on the train" are transmitted.

  Further, if the user carrying the mobile communication terminal 1 is not on the train, the boarding flag FRG included in the mobile terminal inquiry response RES5 becomes “0”, so the location information server 60 The boarding information indicating “on the train” is not transmitted to the client terminal 70.

As described above, according to the third embodiment, the location information server 60 determines whether or not the mobile unit identification number IDt is stored in the mobile terminal location management device 50B based on the boarding flag FRG. 70, it can be notified whether the user of the mobile communication terminal 1 is on the train.
Further, since the location information server 60 acquires location information from the mobile communication terminal 1, it can provide this to the client terminal 70.

<3-3. Modification of Third Embodiment>
In the third embodiment described above, as in the second embodiment, the operation management device 30 detects that the mobile body 2 such as a train has moved, and notifies the mobile body position management device 40A of the operation information INFx. The mobile body location management device 40A converts the operation information INFx into location registration area information INF, and the mobile terminal location management device 50B updates the contents of the first location table TBL1. Then, the location information server 60 transmits a mobile terminal inquiry request REQ5 to the mobile terminal location management device 50B, acquires location registration area information INF of the mobile communication terminal 1, and moves based on the location registration area information INF. The communication terminal 1 is inquired about position information.

In this case, when the mobile terminal location management device 50A receives the mobile terminal inquiry request REQ5 from the location information server 60, the processing from step S5 to step S10 shown in FIG. 2 is performed, and the mobile terminal location management device 50A performs location registration. The area information INF is acquired and transmitted to the position information server 60. The location information server 60 may inquire location information to the mobile communication terminal 1 based on the received location registration area information INF.

<4. Fourth Embodiment>
<4-1: Configuration of Fourth Embodiment>
The position information providing system according to the fourth embodiment is the position information of the third embodiment, except that the detailed operation of the operation management apparatus 30 and the mobile body position management apparatus 40B are used instead of the mobile body position management apparatus 40A. It is configured in the same way as the providing system.

  First, the operation management device 30 returns the operation information INFx to the mobile location management device 40B only when there is an inquiry from the mobile location management device 40B. The operation information INFx is not notified to the moving body position management device 40B.

  Next, FIG. 13 is a block diagram showing a configuration of the mobile object location management device 40B. The mobile body location management device 40B is different from the mobile location management device 40A shown in FIG. 2 in that it includes a management table TBLk.

  FIG. 14 is an explanatory diagram showing an example of the contents stored in the management table TBLk. The management table TBLk includes a plurality of records Rc1, Rc2,..., And one record stores the mobile body identification number IDt, operation information INFx, and recording time T of each mobile body 2 in association with each other. Here, the recording time T is the time when the operation information INFx is recorded in the management table TBLk. The control unit 51 acquires the system time from a timer unit (not shown) at the time of recording, and writes this as the recording time T. In the example shown in FIG. 14, “136 degrees east longitude, 36 degrees north latitude” is recorded at 13:00 in the management table TBLk as the moving body position information INF1 corresponding to the moving body identification number IDt “A01234”.

<4-2: Operation of Fourth Embodiment>
Next, the operation of the position information providing system according to the fourth embodiment will be described with reference to FIG. FIG. 15 is a sequence diagram showing the operation of this system.
First, Step S41 and Step S42 until the location information server 60 transmits the mobile terminal inquiry request REQ7 are the same as Steps S31 and S32 described above.

  Next, the mobile terminal location management device 50 searches the second location table TBL2, and determines whether or not the mobile unit identification number IDt corresponding to the terminal identification number IDm is stored in the location registration area information column. If it is stored, the boarding flag FRG becomes “1”, and if it is not stored, the boarding flag FRG becomes “0” (step S43).

  When the mobile unit identification number IDt is stored, the mobile terminal location management device 50 transmits an operation status inquiry request REQ8 including the mobile unit identification number IDt to the mobile unit location management device 40B (step S44).

  The mobile body position management device 40A searches the management table TBLk based on the mobile body identification number IDt, and reads the corresponding operation information INFx and the recording time T. When the operation information INFx is not stored, or when the current time has passed a predetermined time from the recording time T, the moving body position management device 40A operates the operation status with respect to the operation management device 30. An inquiry request REQ9 is transmitted (step S45).

  The operation management device 30 generates operation information INFx of the moving body 2 based on the moving body identification number IDt, and transmits an operation status inquiry response RES9 including this to the moving body position management device 40B (step S46). At this time, the control unit 41 of the mobile body position management device 40B updates the storage contents of the management table TBLk using the newly acquired operation information INFx, and also updates the updated time in the column of the recording time T of the management table TBLk. Recording is performed (step S47).

  Thereafter, the mobile body location management device 40B transmits an operation status inquiry response RES8 including the operation information INFx to the mobile terminal location management device 50 (step S48). When the operation information INFx is stored in the management table TBLk and the current time has not passed the predetermined time from the recording time T, the mobile body position management device 40B performs the processing in steps S45 to S47. Is omitted and the operation status inquiry response RES6 is directly transmitted to the mobile terminal location management device 50B (step S48). Next, the mobile terminal location management device 50B transmits the mobile terminal inquiry response RES7 including the operation information INFx to the location information server 60 (step S49).

  Next, the position information server 60 separates the operation information INFx into the moving body position information INF1 and the related position information INF2, and predicts a future position based on the related position information INF2.

  For example, the user carrying the mobile communication terminal 1 is on the mobile body 2 whose mobile body identification number IDt is “A01234”, and the storage content of the management table TBLk is shown in FIG. It is assumed that there is a position information inquiry request REQ4 from the client terminal 70 for the terminal 1. In this case, through the processes of steps S42 to S49, the position information server 60 acquires “Azusa 2” as the related position information INF2. Then, based on the timetable data stored in the hard disk 65 in advance, predicted position information indicating the future position of Azusa 2 is generated. For example, if arriving at Matsumoto after 18 minutes, “arrival at Matsumoto after 18 minutes” is set as the predicted position information.

  Thereafter, the position information server 60 transmits the mobile terminal position information response RES6 including the mobile body position information INF1, the related position information INF2, and the boarding information to the client terminal 70 (step S20). In the specific example described above, the mobile terminal position information INF1 indicating “138 degrees east longitude / 36 degrees latitude”, the related position information INF2 indicating “Azusa 2”, and “arriving in Matsumoto after 18 minutes” for the client terminal 70. ”And the boarding information indicating“ on the train ”are transmitted.

As described above, according to the fourth embodiment, since the operation information INFx and the terminal identification number IDm are associated using the mobile object identification number IDt as a key, the mobile communication is performed based on the operation information INFx acquired from the operation management device 30. The current position and future position of the terminal 1 can be provided to the client terminal 70.
Further, even when the mobile unit 2 is passing through the inside of the tunnel and the radio wave does not reach, for example, the current position and the future position of the mobile communication terminal 1 can be provided to the client terminal 70.

  Furthermore, since the management table TBLk also stores the recording time T when the operation information INFx is recorded, if a certain time has passed and the reliability of the operation information INFx has decreased, new operation information INFx is stored. Is obtained from the operation management device 30, and if the time has not passed, the operation information INFx recorded in the management table TBLk is used, so the number of inquiries to the operation management device 30 is reduced and high reliability is obtained. It becomes possible to provide position information under the sexuality.

<4-3. Modification of Fourth Embodiment>
In the above-described fourth embodiment, the mobile body position management device 40B inquires the operation management device 30 about the operation information INFx as necessary. However, the present invention is not limited to this. The operation management device 30 detects that the operation information INFx has been changed, and using the change detection as a trigger, the operation management device 30 transmits the changed operation information INFx to the mobile body position management device 40A, and the management table The stored contents of TBLk may be updated. In this case, the stored contents of the management table TBLk can always be the latest, so that the position information server 60 can perform accurate position prediction, and the mobile body position management device 40A can also record the recording time T It is possible to omit the determination of whether or not to make an inquiry based on.

  As described above, according to the present invention, when a user carries a mobile communication terminal and gets on a moving body such as a train or a bus, the location registration area information is registered without consuming radio resources. Can do. Moreover, according to this invention, position information can be provided reliably and position information can also be provided in the future.
