I do. And the gateway service exchange 22
Receives the location information of the shared terminal 40 from the PHS server 33 and reports it to the service control computer 10. The service control computer 10 receives the location information registered in the PHS server 33 (see the item “HLR” in the column (6) in FIG. 2), and sets the flag “PVF” indicating that the shared terminal 40 is in the PHS mode to “ 1 "and the flag" GVF "to" 0 ". The description of the item indicating the position of the shared terminal 40 is the content indicating the communication range of the PHS server 33.

Next, the shared terminal 40 moves within the PHS communication area (see the state (7) in FIG. 3 and the (7) column in FIG. 2). In this case, the HLR of the PHS server 33 updates the location information of the shared terminal 40. The gateway service exchange 22 transmits the update information to the service control computer 10.
Send to The service control computer 10 receives the update information, but does not update the management information because there is no change in the management state of the shared terminal 40.

Next, from the state (7), the power of the shared terminal 40 is turned off within the PHS communication area (see the state (8) in FIG. 3 and the (8) column in FIG. 2). In this case, both the HLRs of the PHS server 33 and the GSM exchange 34 fail in the location registration (LR) of the shared terminal 40. The gateway service exchange 22 includes a PHS server 33 and a GSM
The exchange 34 receives the information indicating that the location registration of the shared terminal 40 has failed, and reports the information to the service control computer 10. The service control computer 10 receives the report from the gateway service exchange 22 (see the item “HLR” in the column (8) of FIG. 2), and sets both the flag “PVF” and the flag “GVF” to “0”. . Further, based on the fact that the report notifying the position of the shared terminal 40 has not been received from the service exchange 21, the description of the item indicating the position of the shared terminal 40 has a content indicating that the shared terminal 40 does not exist in any communication area. .

Further, from the state (7), the user moves into the communication area of the home cordless telephone base unit (HBU) 31 without turning off the power (see the state (9) in FIG. 3 and the (9) column in FIG. 2). .
In this case, the shared terminal 40 is a PHS (Cordless)

Report to 0. The service control computer 10 receives the report from the gateway / service exchange 22 (see the item “HLR” in the column (9) in FIG. 2), and sets the flag “PV”.
F "and the flag" GVF "are both set to" 0 ". Further, in response to the report from the service exchange 21, the description of the item indicating the position of the shared terminal 40 is set to the content indicating the communication range of the home cordless telephone base unit (HBU) 31.

Further, from the state (7), the mobile terminal moves into the communication area of the private branch exchange (PBX) 32 without turning off the power (see the state (10) in FIG. 3 and the (10) column in FIG. 2). in this case,
The common terminal 40 enters the PHS (PBX) mode,
Both the server 33 and the HLR of the GSM switch 34 lose track of the shared terminal 40. Gateway service exchange 2
2 receives information indicating that the PHS server 33 and the GSM exchange 34 have lost sight of the shared terminal 40, and reports the information to the service control computer 10. On the other hand, the private branch exchange (PBX) 32 detects the presence of the shared terminal 40, and the service exchange 21 receives the position information of the shared terminal 40 from the private branch exchange (PBX) 32 and reports it to the service control computer 10. The service control computer 10 receives the report from the gateway service exchange 22 (see the item “HLR” in the column (10) in FIG. 2), and sets both the flag “PVF” and the flag “GVF” to “0”. . Further, in response to the report from the service exchange 21, the description of the item indicating the position of the shared terminal 40 is entered into the private branch exchange (PB
X) Content indicating 32 communication areas.

As described above, the function of the PHS system and G
The shared terminal 40 having the SM function is provided with a PHS system service, that is, a service provided via the PHS network, a home cordless telephone base unit (HBU) and a private branch exchange (PBX), and a service provided by the GSM network. Can be enjoyed seamlessly.

The position of the shared terminal 40 can be determined by the HLR of the exchange on each mobile communication network even if the terminal 40 moves over each communication network (public telephone network (PSTN), PHS network, GSM network).
The location is automatically detected by the location registration (LR) by the LTE and the location detection by the exchange on the public telephone network (PSTN), and the service control computer 10 manages the location automatically. Therefore, in the shared terminal 40,
One common personal number may be used in each communication network.

Further, by operating the management information in the service control computer 10, the usage amount of the shared terminal 40 in each communication network can be easily grasped, so that billing can be performed collectively. Therefore, the user of the shared terminal 40 only has to pay for one common charge for each communication network.

Although the present invention has been described with reference to the preferred embodiments, the present invention is not necessarily limited to the above embodiments. For example, in this embodiment, the shared terminal has both the PHS function and the GSM function, and
TN), the PHS network, and the GSM network have been described. However, it is needless to say that the present invention can be applied to shared terminals corresponding to various other communication networks.

[0045]

As described above, according to the position management device and the position registration system of the communication mobile terminal of the present invention,
Even when a communication mobile terminal capable of mode switching for receiving a communication service from a plurality of communication networks moves across the plurality of communication networks, the service provided by each communication network can be seamlessly enjoyed. Therefore, it is sufficient to use one common personal number in each communication network, and the service of each communication network can be received by a simple operation.

Further, since the usage amount of the communication mobile terminal in each communication network can be easily grasped, billing can be performed collectively. Therefore, the user of the communication mobile terminal only has to pay for one common charge for each communication network, which has the effect of reducing the complexity of the payment procedure.
