Embodiment
An embodiment of the present invention will be described in detail with reference to the drawings, taking a private telephone system as an example.
[0013]
FIG. 1 is a block diagram showing the overall configuration of a communication management system according to the present invention.
[0014]
In FIG. 1, 1 is a private branch exchange, 1a is a central control unit, 1b is a storage unit, 1c is a communication path unit, 1d, 1e and 1f are connection interfaces, 1g is an input unit, and 1h is a timing unit. 2a, 2b and 2c are radio base stations, and 3a, 3b and 3c are portable mobile terminals (hereinafter also referred to as “PS”).
[0015]
The private branch exchange 1 is shown inside a solid line in the figure, and is controlled by a central control unit 1a that controls the whole, and location registration data and location registration regulations of the mobile mobile terminal sent from the mobile mobile terminal via the radio base station. Location registration in the storage unit 1b via the central control unit 1a, the storage unit 1b for storing various data such as necessary data (for example, location registration restriction time zone data, radio base station data and portable mobile terminal group data) Performs call control with an input unit 1g for inputting various data necessary for regulation, a clock unit 1h for clocking the current time, a call path unit 1c for controlling a call between portable mobile terminals, and the radio base stations 2a, 2b, and 2c. Connection interfaces 1d, 1e, and 1f.
[0016]
The radio base stations 2a, 2b, and 2c are connected to the connection interfaces 1d, 1e, and 1f, and the PSs 3a, 3b, and 3c in each area A, area B, and area C, which are call areas, have their respective areas. The private branch exchange 1 is connected through a radio base station to be managed.
[0017]
FIG. 2 is a conceptual diagram showing communication management information stored in the storage unit 1b of the private branch exchange 1 in the state shown in FIG.
[0018]
The mobile terminal transmits group information (assuming that the groups to which PS3a, PS3b, and PS3c belong are group A, group B, and group C, respectively) to the private branch exchange 1 via the radio base station that manages each area. Then, the central control unit 1a registers the belonging group and the position registration information 1 as communication management information in the storage unit 1b.
[0019]
Based on this communication management information, the central control unit 1a determines that PS3a, which belongs to group A, exists in area A, which is a call area for radio base station 2a, and PS3b, which belongs to group B, is a call area for radio base station 2b. It is recognized that PS3c, which belongs to area B, is located in area C, which is a call area of the radio base station 2c. In this case, since all of the location registration information 2 to N are “none”, it is recognized that there is no portable mobile terminal other than the location registration information 1.
[0020]
FIG. 3 is a conceptual diagram showing the location registration restriction information stored in the storage unit 1 b of the private branch exchange 1.
[0021]
The location registration restriction information is input by the input unit 1g and stored in the storage unit 1b via the central control unit 1a.
[0022]
The content of the regulation number 1 is that the regulation date is “Monday to Friday”, the group to which it belongs is “all” (that is, all portable mobile terminals), the regulation start time is 12:00, the regulation end time is 13:00, The restricted area is area A (that is, the communication area of the radio base station 2a), and for example, the area A where the cafeteria is located for all portable mobile terminals during the lunch time on work days (Monday to Friday) of a company or the like Registration is restricted. In addition, the content of the regulation number 2 is that the regulation date is “October 1, 1998”, the belonging group is “B”, the regulation start time is 8:00, the regulation end time is 9:00, and the regulation area is the area C (that is, the communication area of the wireless base station 2c), for example, in the morning of a predetermined day (in this case, October 1, 1998) in a company or the like (in this case, 8:00 to 9:00) Location registration of the area C where the auditorium is located is restricted for portable mobile terminals of a certain department (in this case, the department designated by the group B).
[0023]
Next, the operation of the communication management system according to the present invention will be described in detail for PS3b with reference to FIGS.
[0024]
It is assumed that PS3b is located in area B shown in FIG. 1, the communication management information is the contents of PS3b shown in FIG. 2, and the location registration restriction information is the contents of restriction number 1 shown in FIG.
[0025]
FIG. 4 is a conceptual diagram showing a transition state of the position registration information of PS 3b, and FIG. 4 (A) is the position registration information immediately before the position registration restriction of restriction number 1 is started.
[0026]
The central control unit 1a constantly monitors the current time measured by the time measuring unit 1h, and compares the restriction start time of the position registration restriction information stored in the storage unit 1b with the current time to thereby restrict the position registration restriction. Judge whether or not to start. In this case, the central control unit 1a starts the position registration restriction from 12:00 of the restriction start time.
[0027]
When the location control is started, the central control unit 1a identifies a radio base station whose location registration is restricted based on the restriction area of the location registration restriction information. In this case, when the central control unit 1a identifies the radio base station 2a and notifies the radio base station 2a via the connection interface 1d that communication necessary for registering the location information of the portable mobile terminal is not performed, The base station 2a recognizes this and does not perform communication necessary for registration of the position information with the central control unit 1a even if the portable mobile terminal requests registration of the position information.
[0028]
FIG. 4B shows location registration information immediately after the location registration restriction of restriction number 1 is started.
[0029]
When the central control unit 1a starts the location registration restriction from 12:00, the mobile control terminal and the restriction area that apply the location registration restriction based on the belonging group and the restriction area of the position registration restriction information stored in the storage unit 1b. And the location registration information in the communication management information is changed. In this case, the central control unit 1a recognizes all portable mobile terminals including the PS 3b and the restriction area A and changes the location registration information in the communication management information. For example, in the PS 3b, the area A is included in the location registration information 2. Added. In this state, if there is an incoming call to PS 3b, a call is made to PS 3b from both area A radio base station 2a and area B radio base station 2b.
[0030]
FIG. 4C shows position registration information in a state where the PS 3b has moved from the state of FIG. 4B to the area A during the position registration restriction period, and further moved from the area A to the area B again.
[0031]
When the PS 3b moves from the area B to the area A, the PS 3b requests the radio base station 2a for location registration, but the radio base station 2a to which location registration restriction is applied actually performs communication for location registration. Instead, a fake signal indicating that the location registration has been normally performed is transmitted to PS3b.
[0032]
When the PS 3b moves from the area A to the area B again, the PS 3b requests the radio base station 2b for location registration, and the radio base station 2b that is not subject to location registration is controlled by the central control via the connection interface 1e. Communication with the unit 1a for location registration is performed. The central controller 1a overwrites the area registration information 1 in the location management information 1 in the communication management information of the PS 3b. In this case, since the area information is the same, the location registration information of the PS 3b matches that before the overwriting. The radio base station 2b transmits a signal indicating that the location registration has been normally performed to the PS 3b.
[0033]
FIG. 4D shows the position registration information in a state where the PS 3b has moved to the area C from the state of FIG. 4C during the position registration restriction period.
[0034]
When the PS 3b moves from the area B to the area C, the PS 3b requests the radio base station 2c for location registration, and the radio base station 2c that is not subject to location registration is connected to the central control unit via the connection interface 1f. Communication with 1a for location registration is performed. The central control unit 1a overwrites the area C in the location registration information 1 in the communication management information of the PS 3b. The radio base station 2c transmits a signal indicating that the location registration has been normally performed to the PS 3b.
[0035]
FIG. 4E shows the position registration information in a state where the position registration restriction is released from the state of FIG.
[0036]
The central control unit 1a constantly monitors the current time counted by the time measuring unit 1h, and compares the restriction end time of the position registration restriction information stored in the storage unit 1b with the current time, thereby comparing the position registration restriction. It is determined whether or not to end. In this case, the central control unit 1a ends the position registration restriction at 13:00 of the restriction end time.
[0037]
Prior to ending the location registration restriction, the central control unit 1a identifies a radio base station that releases the position registration restriction based on the restriction area of the position registration restriction information. In this case, the central control unit 1a identifies the radio base station 2a, and then notifies the radio base station 2a via the connection interface 1d that communication necessary for registering the location information of the portable mobile terminal is performed. The radio base station 2a recognizes it and returns to a normal state in which position information is registered. In addition, the central control unit 1a recognizes the mobile mobile terminal and the restriction area from which the position registration restriction is canceled based on the group and restriction area of the position registration restriction information stored in the storage unit 1b, and includes the communication management information. Change location registration information. In this case, the central control unit 1a recognizes all portable mobile terminals including the PS 3b and the restriction area A and changes the position registration information in the communication management information. For example, in the PS 3b, the area A of the position registration information 2 is Deleted. In this state, if there is an incoming call to PS3b, a call is made from the radio base station 2c in area C to PS3b.
