Multiple base station controllers 10, ... connect with multiple base stations 10-1, ..., 10-n, and one base station controller has one or more base stations 10-1, ..., 10 -n) and wirelessly receive signals from each of the base stations 10-1, ..., 10-n and control the processing of the received signals.

The personal communication switch 20 is connected with a plurality of base station controllers 10, ..., and goes through a plurality of base stations 10-1, ..., 10-n. In case of call from other exchange and own station, connect call from other station and own station, connect call by switching operation, and perform the process of charging.

The exchange includes an Access Switching Subsystem (ASS) 160, an Interconnection Network Sub-system (INS) 190, and a Central Control Subsystem (CCS) (not shown in the figure). It is possible to configure a switch and exchange information with each other.

The connection network control subsystem 190 is located at the center of the system and serves to connect the match exchange subsystem 160 with each other or between the match exchange subsystem 160 and the central control subsystem.

In addition, the network control subsystem 190 performs a centralized function such as number translation, route control, and space switch connection among call processing functions, and is also responsible for generating and distributing a system clock by providing a network synchronizer. . It also controls the visited subscriber.

The match exchange subsystem 160 includes subscriber and relay line matching, time switches, various signaling devices, and the like to perform most call processing and self-operating maintenance functions.

The visitor location register (VLR) 170 is located in the network control subsystem 190 of the personal communication exchange and receives and stores information of a plurality of subscribers temporarily.

For example, if a temporarily registered subscriber has moved to another location, this subscriber information is lost. If a new subscriber has entered, the subscriber information is received from the home location register 30 and stored.

In addition, the home location register 30 is connected to a plurality of exchanges containing subscriber information such as code numbers of the subscribers and other service information, for example, additional service information, and serves as a kind of database.

The home location register 30 communicates with a number of personal communication exchanges and also transmits and receives subscribers' information to each visited subscriber management block 170 within each personal communication exchange 20.

The home location register matching block 150 is a block for matching information transmitted and received with NO.7 to a signal usable at the exchange for matching with the home location register.

The base station controller matching block 110 serves to convert a signal coming from the base station controller 10,... Into a signal usable by the personal communication exchange 20.

In addition, a mobile call control block (PCS call control PCC) may be divided into an originating mobile call control block 130 and an incoming mobile call control block 120.

The outgoing mobile call control block 130 is a block that is connected to the visited subscriber management block 170 and the number translation block 180 to process the numbered outgoing subscriber information.

When the originating mobile call control block 130 receives the requested originating subscriber information from the home location register 30, the originating mobile call control block 130 transmits a mobile call request to the visited subscriber management block 170 when the local call is made.

The called mobile call control block 120 is a block which is connected to the visited subscriber management block 170 and the number translation block 180 to process the numbered called subscriber information.

The path through which the paging response is delivered in the terminating mobile call control block 120 transmits a paging request to the corresponding base station controller 10,..., And the base station controller 10,. When the signal is transmitted back to the called terminal at ..., 10-n, the called terminal is again connected to the base station 10-1, ..., 10-n, the base station controller 10, ..., the called mobile call. The paging response is passed to the control block 130.

An access switching processor-wireless (ASP-W) 140 is a processor that connects to a plurality of base station controllers to accommodate mobile subscribers.

The ASP-W 140 is divided into a base station controller matching block 110 and a mobile call control block. In addition, the PCC call control block (PCC) is an originating subscriber mobile call block 130 and a called subscriber mobile call block 120. Can be divided into

The number translation block 180 is a block for translating a number according to a number translation request of a call received from each mobile call control block.

Referring to FIG. 2, a method for processing an outgoing call during a search in the originating mobile call control block 130 according to the present invention will be described. First, the search includes a plurality of mobile subscribers in the visited subscriber block. In the processor area, if the called party's information is not known in which processor area, the processor search is performed.

When the mobile subscriber makes a call request to the outgoing mobile call control block 130, the outgoing mobile call control block 130 receives it and transmits it to the visited subscriber management block 170 (step 200).

Wait for the incoming information to be received after transmission (step 202).

The originating mobile call control block 130 receives the originating call release processing request generated when the calling subscriber releases the call during the search (step 204).

In the outgoing mobile call control block, the call must be released, but the call is not released. Therefore, the call is waited for the call to be released (step 206).

Outgoing mobile call control block 130 receives the incoming process number from incoming mobile call control block 120 if the incoming process succeeds in paging (step 208).

In the outgoing mobile call control block 130, when the process number is received, the outgoing release call notification is the incoming mobile call control block 120 (step 210).

As described above, when the release processing is performed in the outgoing mobile call control block 130 and the incoming mobile call control block 120, the call processing ends (step 212).

Referring to FIG. 3, FIG. 3 is a flowchart illustrating a process of processing an outgoing call abandonment during a search in the visited subscriber block 170.

First, the visited subscriber management block 170 receives a mobile subscriber call request from the originating mobile call control block 130 (step 300).

The visited subscriber management block 170 sends a search request to the incoming call processing block when the location area identifier (LAI) information of the called subscriber requested by the outgoing mobile call control block 130 does not exist (step 302). ).

The visiting subscriber management block 170 receives the incoming busy registration information in the incoming mobile call control block 120 (step 304).

When the incoming state receives the information to register as busy, the incoming state is registered as busy so that the middle abandoned call is not connected during the search (step 306).

Referring to FIG. 4, FIG. 4 is a flowchart illustrating a process of performing an outgoing call during a search in the incoming mobile call control block 230.

Incoming mobile call control block 120 receives a search request from visiting subscriber management block 170 (step 400).

The terminating mobile call control block 120 transmits a paging request signal to the base stations 10-1, ..., 10-n and the called subscriber via the base station controller 10, ... (step 402).

Incoming mobile call control block 120 waits for a paging response from the base station controller 10,... (Step 404).

When the called subscriber responds to paging, the called mobile call control block 120 transmits the paging signal transmitted in step 402 described above to the base station 10-1, ..., 10-n and the base station controller 10 .... Receive via 406.

After receiving the paging, the incoming mobile call control block, which processes the incoming call, informs the originating mobile call control block 130 of its incoming process number (step 408).

The subscriber registers with the visited subscriber management block 170 that the called party is busy (step 410).

Incoming mobile call control block 120 transmits an incoming mobile subscriber occupation notification to outgoing mobile call control block 130 (step 412).

While the above-mentioned incoming mobile subscriber occupancy notification is processed in the outgoing mobile call control block 220, the incoming mobile call control block 120 waits until a response comes (step 414).

After waiting, the originating call control block 130 receives a call release notification from the originating call control block 130 (step 416).

If the originating release notification is received, the incoming call processing is released (step 418).

As described above, the present invention sends an incoming mobile subscriber occupancy notification from the incoming mobile call control block 120 to effectively terminate the outgoing call abandoned call that may occur in the originating mobile call control block in the calling mobile call control block and the incoming mobile call control block. By doing so, it is possible to increase the utilization of communication resources and the resistance of the program.
