An input unit 1g for inputting maximum value data of the number of terminals, a communication path unit 1c for controlling a call between portable mobile terminals, and a wireless base station 2a
It is composed of connection interfaces 1d, 1e, 1f and the like for controlling a call with 2b and 2c.

The radio base stations 2a, 2b and 2c are connected to connection interfaces 1d, 1e and 1f, respectively. It is connected to the private branch exchange 1 through wireless base stations that manage the respective areas.

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

The communication management information shown in FIG. 2A includes radio base station information, maximum registration number information, location registration number information, and location registration excess number information, and is associated with each radio base station. The maximum number of portable mobile terminals that can be position-registered, the number of portable mobile terminals whose position is normally registered, and the number of portable mobile terminals whose position has been registered because registration restrictions have been canceled are managed.

When the portable mobile terminal registers a position in the private branch exchange 1 via a radio base station that manages each area, the central control unit 1a adds 1 to the current number of registered positions 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).

The terminal management information shown in FIG. 2B includes location registration priority information and incoming frequency information. In this case, the position registration priority information is given in advance in the range of A to C (but is not limited to this range) for each portable mobile terminal, and the position registration priority is registered in the order of A to C. Regulations are lifted. The incoming call frequency information is the number of incoming calls in the past month managed for each portable mobile terminal, and the position registration restriction is released in descending order of this number.

Next, the operation of the communication control apparatus according to the present invention will be described in detail with reference to FIGS.
In the state shown in FIG. 7, only PS3b first moves to area A, and then PS3c moves to area A via area B. The condition for canceling the position registration restriction is that the position registration priority is only rank A and the incoming call is not received. Assume the frequency is more than 100 times.

FIG. 3 is a conceptual diagram showing the communication management information stored in the storage unit 1b of the private branch exchange 1, and shows how the number of registered locations 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". Becomes On the other hand, the central control unit 1a
Since the number of location registrations of “a” has already reached the maximum number of registrations “10”, referring to the terminal management information in FIG.
It is determined whether or not b satisfies the condition for canceling the location registration restriction. In this case, the location registration priority rank B and the release condition are not satisfied, but the condition that the incoming call frequency is 100 times or more satisfies the condition. . However, the central control unit 1a
Does not perform location registration if the portable mobile terminal does not satisfy the location registration restriction release condition.

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”, while the central control unit 1a is the radio base station 2a Has already reached the maximum number of registrations “10”, and the terminal management information shown in FIG.
It is determined whether 3c satisfies the condition for canceling the location registration restriction. In this case, the condition that the frequency of incoming calls is not more than 100 times is not satisfied, but the location registration priority is rank A and the release condition is satisfied. . However, the central control unit 1a
Does not perform location registration if the portable mobile terminal does not satisfy the location registration restriction release condition.

When a call arrives at the portable mobile terminal whose location is registered in this way, the call is connected according to a normal incoming call protocol, and communication with the partner terminal becomes possible.

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, obtains the communication management information of the radio base station from the storage unit 1b. Then, the process proceeds to step 101.

In step 101, the central control unit 1a compares the maximum registration number information and the position registration number information in the communication management information, and determines 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, the process proceeds to step 103.

The central controller 1a obtains terminal management information of the portable mobile terminal in step 103, and
Then, it is determined whether or not the condition for canceling the location registration restriction is satisfied. If the condition for canceling the location registration restriction is satisfied in step 104, the central control unit 1a proceeds to step 102, executes the location registration and ends, but the cancellation condition is not satisfied. In this case, the processing shifts to step 105, where the location registration is rejected and the processing ends.

[0032]

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. Further, even when the location registration is restricted, the location registration is performed on the portable mobile terminal that satisfies the predetermined release condition, so that a specific portable mobile terminal can be called.
