Abstract

PROBLEM TO BE SOLVED: To offer call services of a specified subscriber, without increasing the load to a system by retrieving a traveling object subscriber to notify a fixed network terminal in the order of a priority number when there is a request for a call out to a key number selected by a fixed network terminal, and notify ing a number to a central processor in a PB signal to immediately finish retriev al and notification processing, when there is a subscriber to be called. SOLUTION: When a call is made from a grouped key number from a fixed network terminal 4 a central processor 2 retrieves a subscriber who belongs to the group from data of a group stored in a main storage device 3, i.e., a number of the group. The processor 2 notifies, according to a guidance, a subscriber's number acquired through retrieval to the terminal 4 in the order of a priority number added at the time of registration. The terminal 4 notifies a subscriber number to the processor 2 in a PB signal, when there is a subscriber to be called among guided subscriber numbers.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a subscriber paging service system in an exchange for mobiles.

When there is an incoming call to the representative number, a search process is performed in the system, and a plurality of mobile terminals located in the area to which the representative number is assigned are simultaneously paging, and a response is made. The caller is making a call to the mobile terminal that had the problem.

[0003]

However, according to the conventional paging method of the mobile terminal in the switching system, if there is a call request to the representative number, the subscribers in the corresponding area are simultaneously paging. Therefore, the load on the switching system is increased.

[0004] Further, since all subscribers in the service area are called and a call is made with the mobile terminal that has responded first, unnecessary calls occur.

An object of the present invention is to provide a service for calling a specific subscriber located in a designated area without reducing the load on the switching system, and to reduce unnecessary calls by designating the subscriber. It is to be.

[0006]

According to the present invention, the subscriber numbers of the mobile subscribers of a plurality of mobile terminals to be grouped and the representative number representing the group are registered, and each of the subscriber numbers is registered. A central processing unit for assigning priorities to mobile terminals, and storing a subscriber number of each mobile subscriber, the representative number, the priority, and a number of a location area in which the mobile subscriber is located; When the central processing unit has an exchange configured with a storage device and a call request is made to the representative number selected by the fixed network terminal, the central processing unit becomes a group group corresponding to the representative number. A search is made for the mobile subscribers belonging to the fixed network terminal. Want to do If there was, the number of the subscriber is notified to the central processing unit at a PB signal, in which case,
A subscriber call service system is provided, in which the search process and the notification process are immediately terminated, and the notified subscriber number is called to make a call with the caller.

Further, according to the present invention, each time the mobile terminal moves, the central processing unit updates the location area number of each mobile subscriber. Is obtained.

Further, according to the present invention, if there is no subscriber who desires to call among the subscriber numbers searched by the central processing unit, a PB signal used for notification of the subscriber number is provided. By sending a different PB signal, a subscriber paging service scheme characterized by terminating without making a call is obtained.

Further, according to the present invention, when the mobile subscriber is not present in the area, the number of the fixed network terminal is stored in the storage device as being on standby, and then the mobile subscriber enters the area in the area. If it is located, the subscriber number of the subscriber of the waiting fixed terminal network is notified to the central processing unit from the storage device, and the central processing unit calls the fixed network subscriber and the mobile subscriber. And a connection between the two is obtained.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a subscriber call service system according to the present invention. In FIG. 1, an exchange 1 is provided with a central processing unit 2 and a main storage device 3, wherein 4 is a fixed network terminal, and 5, 6, and 7 are mobile terminals.

Next, a case where the fixed network terminal 4 issues a call request to a certain mobile subscriber from among unspecified mobile subscribers located in a certain location area will be described. . First, the subscriber numbers of a plurality of mobile terminal units (5, 6, and 7 in FIG. 1) to be grouped and a representative number representing the group are registered in the exchange A (not shown). At the same time, priorities are given to the mobile subscribers of the mobile terminals 5, 6, and 7, respectively. In the main storage device 3 in the exchange, a subscriber number of each mobile subscriber, a representative number representing a group to which a call is desired, a call priority, and an area where the mobile subscriber is located (location area). Are stored and the information is saved as a calling subscriber registration list.

FIG. 2 shows a specific example of a subscriber registration list, in which mobile terminals 5, 6, and 7 have priority levels 1, 3, respectively.
FIG. 11 is a diagram showing a subscriber registration list when the number is assigned to 2. As shown in FIG. 3, every time a mobile terminal grouped moves, the area where the mobile terminal is currently located is automatically registered in the central processing unit 2 and the main storage device 3 is registered. Is stored. This location registration is updated and registered each time the mobile terminal moves.

As shown in FIG. 4, when a call is made from a fixed network terminal 4 (see FIG. 1) to a grouped representative number, that is, when a call is made by selecting a representative number from a caller, central processing is performed. The device 2 searches for a subscriber belonging to the group from the data of the group stored in the storage device 3, that is, the representative number of the group. The central processing unit 2 notifies the fixed network terminal 4 of the subscriber numbers obtained by the search with guidance in the order of the priority numbers given at the time of registration.
When there is a subscriber who wants to make a call among the guided subscriber numbers, the fixed network terminal 4 notifies the central processing unit 2 of the subscriber number by a PB signal.

The central processing unit 2 receives the P from the fixed network terminal 4
When the subscriber number is notified by the B signal, the search process and the notification process based on the guidance are immediately terminated, and the notified subscriber number is called to make a call. If there is no subscriber who wants to make a call among the retrieved subscriber numbers, for example, "#" is transmitted by a PB signal,
Can exit without making a call. Of course P
It goes without saying that the B signal is not limited to “#”.

As shown in FIG. 5, when no mobile subscriber is present in the corresponding area, the number of the fixed network terminal 4 is stored in the main storage device 3 as waiting. Thereafter, when the mobile subscriber registers in the area, the exchange 1 stores the standby fixed network subscriber number from the main memory 3 into the central processing unit 2.
Notify to The central processing unit 2 calls the fixed network subscriber Y and the mobile terminal 7 to connect them.

[0016]

According to the present invention, the caller selects from the subscribers located in the designated area and calls the corresponding subscriber, thereby reducing unnecessary call processing and reducing the number of calls to the switching system. The load can be reduced.

Further, according to the present invention, since the caller can also select the most suitable mobile subscriber, it is possible to eliminate useless calls.
