DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a principle configuration diagram of the first embodiment. An exchange 5 is provided in one area, and an area management device 6 that manages the area is connected to the exchange 5. A plurality of base stations 3 and 4 are connected to the exchange 5 by wire. The base stations 3 and 4 perform wireless communication with a large number of mobile terminal devices 1 and 2.
[0010]
In the mobile terminal device 1, the movement history data processing means 1a periodically receives the recognition code (base station ID) of the nearest base station 3 and processes it in time series to generate movement history data, Transmit to the base station as necessary. The base station 3 transmits this movement history data to the exchange 5. In the exchange 5, the movement history data relay means 5a receives the movement history data and relays it to the area management device 6.
[0011]
In the area management device 6, the statistical data generating means 6 a generates statistical data for each mobile terminal device in its own area based on the movement history data received from the exchange 5. This statistical data is managed by the statistical data management means 6b, and is used when the exchange 5 selects a base station that performs simultaneous calling.
[0012]
The exchange 5 executes various communication controls according to the statistical data. For example, a zone in which the mobile terminal device 1 is currently present is predicted from the statistical data, and control is performed such as making a simultaneous call to the base station 3 in that zone.
[0013]
Next , a specific configuration of the first embodiment will be described.
FIG. 2 is a functional block diagram of the communication system according to the first embodiment. In the communication system, an area AR1, an area AR2, and the like are connected via a network 15. The network 15 is connected with an HLR (Home Location Resistor) 10 as a network management device. The HLR 10 stores, in the storage device 10a, statistical data of movement history of each mobile terminal device described later.
[0014]
In the area AR1, one exchange 11 is provided and connected to a number of base stations. Here, for simplicity of explanation, five base stations BS11, BS12, BS13, BS14, and BS15 are shown. Similarly, one switch 13 is provided in the area AR2, and is connected to a number of base stations. Here, three base stations BS21, BS22, BS23 are shown.
[0015]
The mobile terminal device PS1 in the area AR1 receives the base station ID from the base station BS11 and the like to know the current position. Then, the mobile terminal apparatus PS1 generates movement history data based on the position data and time data.
[0016]
FIG. 3 is a diagram illustrating an example of movement history data of the mobile terminal apparatus PS1. Here, the ID of the mobile terminal device PS1 is P0000001, and the IDs of the base stations BS11, BS12, BS13, BS14, BS15 are B00000011, B00000012, B00000013, B00000014, B00000015. Assuming that the mobile terminal device PS1 has moved through all the zones, the time when each zone is passed is recorded. Here, data is taken when the zone of the base station is switched, but it may be at regular intervals.
[0017]
Returning to FIG. 2, the movement history data of the mobile terminal device PS1 is automatically transmitted to the exchange 11 via the nearest base station at regular intervals (for example, every hour). The exchange 11 that has received the movement history data sends it to a VLR (Visitor Location Resistor) 12. The VLR 12 stores the movement history data of the mobile terminal device PS1 in the storage device 12a, generates statistical data of the movement history of the mobile terminal device PS1 based on the movement history data, and stores the statistical data in the storage device 12a.
[0018]
FIG. 4 is a diagram showing an example of movement history statistical data in the VLR 12. The VLR 12 generates statistical data of the area AR1 of the mobile terminal device PS1. Here, statistical data is generated for each time zone of 6 hours width. The statistical data includes, for example, the probability of movement from a certain base station to surrounding base stations.
[0019]
Returning to FIG. 2, the VLR 12 transmits the generated statistical data to the HLR 10. After transmission, the statistical data relating to the mobile terminal device PS1 in the storage device 12a is deleted when the mobile terminal device PS1 is no longer in the area AR1.
[0020]
On the other hand, the HLR 10 that has received the statistical data of the mobile terminal device PS1 from the VLR 12 collects the statistical data from each area for each mobile terminal and stores them in the storage device 10a as shown in FIG.
[0021]
As described above, each time the mobile terminal device PS1 moves in the area, the HLR 10 that owns the statistical data of each mobile terminal device reads the past statistical data regarding the area of the mobile terminal device PS1 and sends it to the VLR in the target area. For example, in FIG. 2, if the mobile terminal device PS1 moves from the area AR1 to the area AR2, the HLR 10 transmits statistical data related to the area AR2 of the mobile terminal device PS1 in the storage device 10a to the VLR 14. Receiving this, the VLR 14 stores the statistical data in the storage device 14 a and further sends this statistical data directly to the exchange 13. The exchange 13 predicts the current position of the mobile terminal apparatus PS1 based on the statistical data, and among the base stations BS21, BS22, BS23, etc., the base station nearest to the current position of the mobile terminal apparatus PS1 and its surrounding base stations Make a general call to the station.
[0022]
The statistical data may be interpreted on the VLR 14 side instead of the exchange 13 and an instruction may be issued from the VLR 14.
The movement history data of the mobile terminal apparatus PS1 in the area AR2 is generated in the same procedure as when in the area AR1, and is transmitted to the exchange 13 side.
[0023]
Next, the functional configuration of each device for executing such communication control will be described.
FIG. 6 is a block diagram showing a functional configuration of the mobile terminal device PS1 according to the first embodiment. In response to the base station ID check request from the history information recording control unit 22a of the movement history control unit 22, the wireless communication unit 21 receives the base station ID from the base station and sends it to the history information recording control unit 22a. Further, the wireless communication unit 21 sends the movement history data from the history information transmission control means 22b of the movement history control unit 22 to the base station.
[0024]
The history information recording control means 22a of the movement history control unit 22 periodically gives a base station ID check request to the wireless communication unit 21 and receives the base station ID of the nearest base station. Then, the time and the base station ID at this time are stored in the history information storage unit 23a of the storage device 23 as movement history data.
[0025]
The history information transmission control means 22b sends the movement history data in the history information storage unit 23a to the wireless communication unit 21 at regular intervals and transmits it to the exchange 11 side via the base station.
FIG. 7 is a block diagram showing a functional configuration of the exchange 11 according to the first embodiment. When the movement history data transmission / reception control unit 11a of the exchange 11 receives a movement history data transmission request from the base station side, it temporarily stocks the ID of the mobile terminal device in the internal waiting queue. Then, the network traffic detection unit 11b is requested to check the load of the network traffic. Upon receiving this request, the in-network traffic detection unit 11b detects in-network traffic and sends a numerical value corresponding to the load to the movement history data transmission / reception control unit 11a.
[0026]
The movement history data transmission / reception control unit 11a calculates the number of terminals that can receive movement history data according to the traffic load in the network, reads the ID from the head of the permission waiting queue, and the number of terminals read out. Send permission notification to. When each movement history data is received from the mobile terminal apparatus that has sent the transmission permission notification, the movement history data transmission / reception control unit 11a sends it to the VLR 12. Then, the ID of the mobile terminal apparatus that sent the movement history data to the VLR 12 is deleted from the permission waiting queue.
[0027]
Here, the configuration of the exchange 11 is shown, but the other exchanges such as the exchange 12 have almost the same configuration.
FIG. 8 is a block diagram showing a functional configuration of the VLR 12 according to the first embodiment. The data transmission / reception control unit 12b of the VLR 12 stores the movement history data sent from the exchange 11 in the history information storage unit 12c of the storage device 12a. The statistical data generation unit 12d generates statistical data as shown in FIG. 4 based on the movement history data in the history information storage unit 12c, and stores the statistical data in the statistical data storage unit 12e of the storage device 12a. The statistical data stored in the statistical data storage unit 12e is transmitted to the HLR 10 at a predetermined timing by the data transmission / reception control unit 12b.
[0028]
Further, when the mobile terminal apparatus PS1 moves from another area, the HLR 10 sends statistical data related to the area AR1 of the mobile terminal apparatus PS1, so the data transmission / reception control unit 12b stores this in the statistical data storage unit 12e. To do.
[0029]
In addition, although the structure of VLR12 was shown here, it is the substantially same structure also about other VLRs, such as VLR14.
FIG. 9 is a block diagram showing a functional configuration of the HLR 10 of the first embodiment. The data transmission / reception control unit 10b of the HLR 10 receives the statistical data from each area AR1, area AR2, etc., and stores it in the statistical data storage unit 10c of the storage device 10a in the format as shown in FIG. Further, the data transmission / reception control unit 10b reads the statistical data from the statistical data storage unit 10c as necessary, and transmits the statistical data to the exchange 11 in the area AR1.
