The personal mobile communication exchange 16 includes a first ASP-W A second ASP-W 20 for communicating with another base station controller, a first ASP 30 for performing a fixed subscriber or trunk line matching function, a first ASP 30, 1, and the second ASP-W 18, 20, respectively, so that the first ASP 30 and the first ASP- (NTP) 22 for translating required numbers from the ASP-W 2 and the ASP-W 18 and exchanging them according to the numbers, and an interface between the first ASP-W 18 and the second ASP- An INP (Inter Networking Processor) 24 for providing a working function, a first ASP 30 and first and second ASP-Ws 18 and 20, and controls the location registration of the corresponding mobile terminal And the first to tenth LRPs 26 and 28.

The present invention will now be described in detail with reference to FIG.

First, a plurality of base stations 12 are formed, and each base station is in wireless communication with a plurality of mobile terminals 10 in the corresponding area, and the base station controller 14 performs wire communication with a plurality of base stations.

That is, a plurality of mobile terminals may be included in one cell managed by one base station, and one base station controller performs wire communication with a plurality of base stations.

Next, the personal mobile communication exchange 16 communicates with the base station controller 14 to perform an exchange function according to the corresponding telephone number dialed by the subscriber.

Here, the first ASP-W 18 of the personal portable communication exchange 16 communicates with the base station controller 14, and the second ASP-W 20 communicates with another predetermined base station controller.

That is, a plurality of ASP-Ws are formed in the personal mobile communication exchange 16, and one ASP-W is connected to one base station controller one by one.

In addition, a plurality of first ASPs 30 are formed to execute a fixed subscriber or a trunk line matching function according to the corresponding telephone number, respectively. The NTP 22 receives the first ASP 30 and the first and second ASP- The INP 24 communicates with the first ASP 30 and the first and second ASP-W 18 and 20, respectively, by communicating with the first ASP 30 and the second ASP-W 18 and 20, respectively, 1, and the second ASP-W (18, 20).

The first to tenth LRPs 26 and 28 are respectively connected to the first ASP 30 and the first and second ASP-Ws 18 and 20 to control the location registration of the corresponding mobile terminal.

Accordingly, the first and second ASP-Ws 18 and 20 control the number of allowable calls per unit time in accordance with the overload state to control the call to the first and second ASP-Ws 18 and 20 And the NTP 22 and the first to tenth LRPs 26 and 28 provide the information to the NTP 22 and the first to the tenth LRPs 26 and 28. The TRAC (Traffic Resource Control Library) And stores information about each ASP including the first ASP 30 in the library.

In this case, the TRCL is located in the LRP and collects the calling subscriber information request number, the called subscriber information request number, and the location registration request number according to the function and periodically transmits the TRC to the TRC block. The TRC (Traffic Resource Control) Refers to the number of LRP services when the LRP is overloaded in the LRP, and stores the LRP limit in the TDSL library.

In addition, when a call is received from the NTP 22 or the first to tenth LRPs 26 and 28 to the first and second ASP-Ws 18 and 20, it is notified from the library whether or not the call is performed.

The NTP 22 and the first to the tenth LRPs 26 and 28 provide their overload information to all the ASPs so that the NTP 22 or the first to tenth LRPs 26 and 28 And all ASPs store the call gap information of the NTP 22 and the first to tenth LRPs 26 and 28 in a library called TDSL and store the call gap information from the library You will be notified of the performance.

FIG. 2 is a schematic diagram showing an embodiment of an overload control method in the case of a mobile call to mobile call (local call) proceeding in a personal mobile communication exchange according to the present invention.

First, when a call is made from the mobile terminal 10 to the personal mobile communication exchange 16 via the base station 12 and the base station controller 14 in the case of a mobile call to a mobile call (local call), the first ASP-W 18 requests the calling subscriber information in the corresponding LRP with the number of the mobile terminal 10 calling the call.

At this time, the first ASP-W 18 checks the overload state of the LRP for the originating subscriber information request and requests the LRP for the originating subscriber if the service is allowed.

When the LRP requests the originating subscriber information, it provides the originating subscriber information request to the library and searches the subscriber information from a predetermined VLR (Visitor Location Register) (not shown in the figure) -W (18) to provide the originating subscriber information.

If the called subscriber is a mobile subscriber, the first or second ASP-W (18, 20) requests the called subscriber information to the corresponding LRP.

At this time, the ASP-W checks the overload of the LRP for the called subscriber information request and requests the corresponding LRP for the called subscriber information when the ASP-W permits the service.

When the LRP receives the called subscriber information request, it provides the called subscriber information request to the corresponding library, finds the called subscriber information from the predetermined VLR, and provides the called subscriber information to the corresponding ASP-W requesting the called subscriber information.

In the personal mobile communication exchange according to the present invention, the overload control method can be applied not only to a personal mobile communication exchange but also to all exchangers using LRP.

As described above, according to the present invention, even when the first and tenth LRPs 26 and 28 are in the overload state in the case of the mobile call to mobile call (local call), the load ratings of the first and tenth LRPs 26 and 28 The service quality of the personal mobile communication exchange is improved by controlling the provision of the information request of the mobile subscriber and the location registration function to maintain a certain level of service.

In addition, in the case of a mobile call to a mobile call (local call), by controlling the overload by the calling subscriber information providing function, the called subscriber information providing function, and the location registration function provided by the first and tenth LRPs 26 and 28, Each function is performed without processing only one function, and overload control is performed by imposing a weight for each function.

That is, in the case of the mobile-to-mobile call (local call) proceeding, the location registration is performed much more than the function of providing the subscriber information among the functions of performing the first and tenth LRP (26, 28) Therefore, overload control is performed by increasing the weight of the location registration function, and weight is given to providing the called subscriber information rather than providing the calling subscriber information.
