The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, an embodiment of the present invention for achieving the above object in detail.

Referring to FIG. 1, FIG. 1 is a block diagram showing an embodiment of a hardware to which the mobile call overload control method of a personal mobile communication switch according to the present invention can be applied. A plurality of base stations 12 each wirelessly communicating with the mobile terminal 10, a base station controller 14 each having a wired communication with the plurality of base stations 12, and a base station controller 14 communicating with the base station controller 14 to exchange according to a corresponding telephone number. A personal mobile communication exchange (16) to perform a function, the personal mobile communication exchange (16) having a first access switching processor (ASP) -W (18) in communication with the base station controller (14), and another base station controller; A second ASP-W 20 to communicate with, a first ASP 30 performing a fixed subscriber or relay line matching function, a first ASP 30 and first and second ASP-Ws 18 and 20 Communicate with each other to perform the required number translations from the first ASP 30 and the first and second ASP-Ws 18 and 20, respectively. NTP (Number Translation Processor) 22 for the exchange according to this, Inter Networking Processor (INP) 24 for providing an interworking function between the first and second ASP-W (18, 20), and 1st to 10th LRP (Local Register Processors) 26 and 28, which are connected to the ASP 30 and the first and second ASP-Ws 18 and 20, respectively, to control the location registration of the mobile terminal. It is made to include.

The present invention made as described above will be described in detail with reference to FIG.

First, a plurality of base stations 12 are formed, each base station wirelessly communicating with a plurality of mobile terminals 10 in a corresponding area, and the base station controller 14 communicates with a plurality of base stations, respectively.

That is, one cell managed by one base station may include a plurality of mobile terminals, and one base station controller communicates with a plurality of base stations by wire.

The personal mobile communication exchange 16 then communicates with the base station controller 14 to perform an exchange function in accordance with the telephone number dialed by the subscriber.

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

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

In addition, a plurality of first ASPs 30 are also formed, each of which executes a fixed subscriber or relay line matching function according to the corresponding telephone number, and the NTP 22 performs the first ASP 30 and the first and second ASP-W. (18, 20) to communicate with each other required number translation from the first ASP (30) and the first and second ASP-W (18, 20), respectively, so that the exchange is made accordingly, and INP (24) The first and second ASP-Ws 18 and 20 provide interworking functions.

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

Accordingly, each of the first and second ASP-Ws 18 and 20 sets an allowable number of calls per unit time according to an overload condition in order to control a call that reaches each of the first and second ASP-Ws 18 and 20. And provide the corresponding information to the NTP 22 and the first to tenth LRPs 26 and 28, wherein the NTP 22 and the first to tenth LRPs 26 and 28 have a first ASP in a library called TRCL. Information about each ASP including the 30 is stored.

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, the library is informed whether or not the call is performed.

The NTP 22 and the first to tenth LRPs 26 and 28 provide their overload information to all the ASPs so that the call enters the NTP 22 or the first to tenth LRPs 26 and 28 from all the ASPs. And all ASPs store the call gap information of NTP 22 and the first to tenth LRPs 26 and 28 in a library called TDSL, and call from these libraries upon request for number translation and location registration. You will be notified whether or not it is performed.

2 is a flowchart illustrating a step-by-step embodiment of a mobile call, i.e., mobile call-to-mobile call overload control method, of a personal mobile communication switch according to the present invention.

First, by checking the overload of the first to tenth LRP (26, 28) to receive the call performance information from a predetermined TDSL library, if the call is performed (110) and transmits the corresponding signal (Qual RQ) according to the NTP (22) If the call is performed by checking the overload of the NTP 22, the number translation is requested (120).

Next, by checking the overload of the first to tenth LRP (26, 28) of the called party and receiving the call performance information from the preset TDSL library, if the call is performed, the corresponding signal (Pcs Tern RQ) is transmitted (130). Checking the overload of the side first and second ASP-W (18, 20) and receiving the call performance information from the preset TRCL library and transmits the signal (Page RQ) if the call is performed (140).

In addition, an embodiment of a mobile call-to-fixed call overload control method according to the present invention is as follows.

First, by checking the overload of the first to tenth LRP (26, 28) to receive the call performance information from the preset TDSL library, if the call is performed, the corresponding signal is transmitted accordingly, and the overload of the NTP 22 is checked to call If so, ask NTP 22 for number translation.

Then, if the called party is a fixed call, the overload of the called party ASP is checked.

As described above, the present invention maintains the stabilization of the switching system even when a mobile call overload occurs in the personal mobile communication switch, so that the service can be continuously maintained at a predetermined level or more, thereby further improving the quality of the personal mobile communication service. It is effective.
