DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the drawings, taking a private telephone system as an example.

FIG. 1 is a block diagram showing a configuration of a communication control device according to the present invention.

In FIG. 1, 1 is a private branch exchange as a communication control device, 1a is a central control unit, 1b is a storage unit, 1c is a communication path unit, 1d, 1e and 1f are connection interfaces, and 1g is an input unit. 2a, 2b and 2c are radio base stations, and 3a, 3b and 3c are portable mobile terminals.

The private branch exchange 1 is shown inside a solid line in the figure.
A central control unit 1a for controlling the whole of the mobile terminal, location registration data of the mobile mobile terminal transmitted from the mobile mobile terminal via the wireless base station, and the maximum number of mobile mobile terminals that can be registered for each wireless base station; Storage section 1b for storing various data such as value data, and storage section 1b via central control section 1a
Input section 1g for inputting the maximum value data of the number of portable mobile terminals, etc., a communication path section 1c for controlling a call between portable mobile terminals, and a connection interface 1d for controlling a call with the radio base stations 2a, 2b, 2c. , 1e and 1f.

The radio base stations 2a, 2b, and 2c are connected to connection interfaces 1d, 1e, and 1f, respectively, and PSs 3a, 3b, and 3c in areas A, B, and C, which are communication areas, respectively. It is connected to the private branch exchange 1 through a wireless base station that manages each area.

FIG. 2 is a conceptual diagram showing communication management information stored in the storage unit 1b of the private branch exchange 1.

The communication management information includes radio base station information, maximum registration number information, and location registration number information. The maximum number of portable mobile terminals that can be location-registered and the current location registration are associated with each radio base station. The number of mobile mobile terminals being managed is managed.

When the portable mobile terminal registers its location in the private branch exchange 1 via the radio base station that manages each area, the central control unit 1a adds 1 to the current number of registered locations and stores it as communication management information in the storage unit 1b. (On the other hand, when the portable mobile terminal leaves the registered area, 1 is subtracted from the current position registration number and stored).

Next, the operation of the communication control apparatus according to the present invention will be described in detail with reference to FIGS.
It is assumed that only PS3b moves to area A first, and then PS3c moves to area A via area B from the state shown in FIG.

FIG. 3 is a conceptual diagram showing the communication management information stored in the storage section 1b of the private branch exchange 1, and shows how the number of location registrations in the communication management information changes as the portable mobile terminal moves around the area. Is shown.

FIG. 3A shows communication management information when only the PS 3b has moved to the area A from the state of FIG. 2, and the number of position registrations of the radio base station 2b is reduced by one to "4". And the number of position registrations of the wireless base station 2a is increased by one, and is “10”, which is the same as the maximum registration number.

FIG. 3B shows the PS from the state shown in FIG.
3c shows the communication management information when moving to the area B, where the number of location registrations of the wireless base station 2c decreases by one to “7”, and the number of location registrations of the wireless base station 2b increases by one and “ 5 ".

FIG. 3 (C) shows PS from the state of FIG. 3 (B).
3c shows the communication management information when moving to the area A, and the number of position registrations of the radio base station 2b is reduced by one to "4", but the number of position registrations of the radio base station 2a has already reached its maximum. Since the number of registrations has reached “10”, the central control unit 1a does not perform position registration even if the PS 3c requests position registration.

FIG. 4 is a flowchart showing a location registration processing routine of the communication control method according to the present invention.

When the central control unit 1a receives a position registration request for the portable mobile terminal from the radio base station, it enters this position registration processing routine, and in step 100, acquires the communication management information of the radio base station from the storage unit 1b. Then, the process proceeds to step 101.

The central control unit 1a compares the maximum registration number information and the position registration number information in the communication management information in step 101, and judges that the position registration is possible if the position registration number information does not reach the maximum registration number information. Then, in step 102, the location registration is executed and the processing is terminated. On the other hand, if the location registration number information has reached the maximum registration number information, it is determined that the location registration is impossible, and in step 103, the location registration is rejected and the processing ends.

[0025]

As described above, according to the communication control apparatus and the communication control method according to the present invention, the maximum number of portable mobile terminals whose location can be registered is determined for each radio base station (however, Even if many people are concentrated in one place at the same time, such as during lunch or when holding various events, only the maximum number of mobile terminals are registered, so congestion may occur. In addition, the system does not go down.
