Description

How to Handle Paging on the Personal Communications Exchange

The present invention relates to a paging processing method in a personal communication exchange, and more particularly, to a paging processing method in a personal communication exchange performing paging processing by managing visited subscriber information and call state information.

As is well known in the art, a process of a mobile subscriber sending an outgoing call to reach a mobile subscriber in his country is as follows.

First, when a mobile subscriber attempts to make a call at the terminal, a call request is received from the terminal, base station, base station controller, and base station controller matching block by the originating mobile call control block.

The outgoing mobile call control block requests outgoing subscriber information from a visitor location register (VLR) to obtain outgoing subscriber information. The originating mobile call control block checks whether the call request of the originating subscriber can be accepted, and notifies the base station controller that the call request is acceptable, if the call request is acceptable.

The base station controller forwards the called number to the calling mobile call control block. The calling mobile call control block forwards the called number to the number translation block and requests number translation. If the called subscriber is the mobile terminal, the number translation block sends the mobile call notification to the originating mobile call control block.

The originating mobile call control block requests the location information of the called party to the home location register via the home location register matching block.

When the originating mobile call control block receives the called location information from the home location register, the originating mobile call control block transmits the mobile call request to the visited subscriber management block in the case of the local call.

The visited subscriber management block forwards the paging request to the terminating mobile call control block in the ASS-W with the called subscriber. The incoming mobile call control block forwards the paging request to the base station controller.

When paging is transmitted to the base station controller, the base station, and the destination terminal, the destination terminal is sent a paging response to the base station, the base station controller, the destination mobile call control block.

The incoming mobile call control block sends an incoming mobile subscriber occupancy notification to the originating mobile call control block.

The originating mobile call control block sends a switch connection notification to the incoming mobile call control block after the switch connection. The incoming mobile call control block initiates incoming call setup.

In the mobile signaling process of the above-described process, conventionally, the visited subscriber management block managing information on the visited subscriber and the call state of the subscriber, that is, the idle state of the call, the call processing state, and the incoming call processing During the call processing process, the connection between processors increases, so that the processing time becomes longer and the subscriber call state information is transferred to another processor even if the subscriber's position is changed in the local exchange. There is a drawback that there is a need to move, and each processor requires a memory allocation for subscriber state management.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks of the prior art, and an object thereof is to provide a visited subscriber location register that can replace the conventional subscriber call state management block and to improve call processing efficiency.

In order to achieve the above object, the present invention provides a visited subscriber management block and an outgoing mobile call for determining whether an outgoing call received from an outgoing mobile call control block controlling a signal coming through a plurality of base stations, a plurality of base station controllers, and a base station controller matching device. In a personal communication switch including a called mobile call control block that connects a calling party and a called party called by a calling party in a control block, when the originating call is found to be a mobile local call in the calling mobile call processing block, information about the called party is determined. Transmitting a mobile call request to a stored visited subscriber management block; In the visited subscriber management block, when the callable state is available, transmitting a paging request from the location information of the called subscriber to the called mobile call processing block that performs call control on the corresponding area; The called mobile call processing block transmits paging, and when a response to paging is received from the called party, registers the call status of the called subscriber as a busy in the visiting subscriber block, and sends outgoing information request to the originating call processing block.

A plurality of base station controllers 10, ..., connect with a plurality of base stations 10-1, ..., 10-n, and one base station controller has one or more base stations 10-1, ..., 10 -n) and wirelessly receive a signal from each of the base stations 10-1, ..., 10-n and control a process of processing the received signal.

The personal communication switch 20 is connected to a plurality of base station controllers 10, ..., and is connected to a plurality of base station controllers 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) (shown in the figure). It is a schematic block diagram of an exchange, which exchanges information with each other and constitutes an exchange.

The central control subsystem provides system-wide maintenance, testing and measurement, billing, and statistical functions, as well as mess storage control management, operators such as cartridge tape (CT), magnetic tape (MT), hard disk, and more. Various control and output door control function and data channel connection function with other system are performed.

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 with 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 functions and self-operating maintenance functions.

In addition, the match exchange subsystem 160 may accommodate a Remote Access Switching Module (RASM) or a Remote System (Remote System), which is a remote system, through an interface circuit.

The visitor location management block (VLR) 170 is located in the INS 190 of the personal communication exchange and serves as a small database for receiving and temporarily storing information of a plurality of subscribers.

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.

The home location register 30 also serves as a large database containing subscriber information such as code numbers of the subscribers and other service information, for example, additional service information.

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 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 switch 20.

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

The originating mobile call control block 120 requests the originating subscriber information from the visited subscriber management block 170 to obtain the originating subscriber information.

In addition, the outgoing mobile call control block 120 transmits the called number to the number translation block 180 to request number translation.

The originating mobile call control block 120 requests the home location register 30 to receive information about the location of the called subscriber via the home location register matching block 150.

When the originating mobile call control block 120 receives the called location information from the home location register 30, the originating mobile call control block 120 transmits a mobile call request to the visited subscriber management block 170 when the local call is made.

Incoming mobile call control block 130 transmits a paging request to the base station controller 10, the base station controller 10 transmits a signal back to the destination terminal to a plurality of base stations (10-1, ..., 10-n) Then, the called terminal again transmits a paging response to the base station 10-1,..., 10-n, the base station controller 10, and the called mobile call control block 130.

In addition, the incoming mobile call control block 130 receiving the paging response sends an incoming mobile subscriber occupation notification to the originating mobile call control block 120.

Then, the outgoing mobile call control block 120 receiving the incoming mobile subscriber occupation notification sends a switch connection notification to the incoming mobile call control block 130 after the switch connection.

Incoming call control block 130 initiates the incoming call setting.

Then, the visited subscriber management block 170 receiving the mobile call request forwards the paging request to the called mobile call control block 130 in the ASP-W 140 where the called subscriber is located.

In the number translation block 18, which has been requested to translate the number, if the number translation result recipient is the mobile call terminal, the originating call control block 120 notifies the mobile call.

The home location register matching block 150 is responsible for registration between the home location register 30 and the personal communication switch 20, and communicates with the home location register 30 with the signal of SS NO. Receives and transmits signals, switches to internal signals commonly used in personal communication switch 20, and switches internal signals of personal communication switch 20 to SS NO. 7 so that signals are transmitted through home location register 30. It also plays a role.

In addition, the home location register matching block 150 notifies the home location register 30 when an inaccessible state occurs when the incoming location information is requested from the originating mobile call control block 120.

The paging processing method in the personal mobile communication exchange of the present invention will be described with reference to FIGS.

The originating subscriber makes a call request to the originating mobile call control block 120 through the base station 10-1, ..., 10-n, the base station controller 10, ..., and the base station controller matching block 110. .

Outgoing mobile call control block 120 requests number translation block 180 for number translation for the number received from the originating subscriber (step 200).

Referring to FIG. 3, the number translation block receives the number translation request signal from the originating mobile call control block (step 300).

The number translation is performed to transmit the number translation result to the calling mobile call control block (steps 310 and 320).

2, the outgoing mobile call control block 120 waits for a response to the number translation after the number translation request and receives a notification that the number received from the calling subscriber is the mobile subscriber (step 210).

The originating mobile call control block 120 forwards a routing information request to the home location register 30 to query the home location register 30 with the home location register matching block 150 (step 220).

Here, the routing information has a digit number, a billing information and a switch ID (MSC identification) digitized by the caller, and as routine information, the calling party's number and the MIN (mobile indicating number) of the called subscriber's terminal. You can also see the exchange to which the called party belongs.

4, home location register matching block 150 receives a routing information request from an originating mobile call control block (step 400).

The home location register matching block 150 requests the above-described routine information from the home location register 30 (step 410), waits and receives the routine information from the home location register 30 (step 420).

The home location register matching block 150 notified of this is notified to the originating mobile call control block again (step 430).

Referring again to FIG. 2, when the outgoing mobile call control block 120 receives routine information from the home location register matching block 150 (step 230), it requests a mobile call to the visited subscriber management block 180 if it is a local call. (Step 240).

In FIG. 5, the visited subscriber management block 180 receives the mobile call request from the originating mobile call control block (step 500) and requests paging to the called mobile call control block 130 (step 510).

In FIG. 6, the incoming mobile call control block 130 receives a paging request and pages the corresponding subscriber through the base station controller 10, ..., base stations 10-1, ..., 10-n (step S). 600).

Then, the called subscriber who receives it receives the response to the paging request to the base station 10-1, ..., 10-n, the base station controller 10, ..., and the base station controller matching block 110. The transmitting and terminating mobile call control block 130 receives a response to the paging request from the base station controller matching block 110 (step 620).

Upon receiving the response to the paging request, the called mobile call control block 130 transmits a called subscriber busy registration request to the visited subscriber management block 170 (step 630).

In the visited subscriber block 170 of FIG. 5, an incoming busy registration registration request is received from the incoming mobile call control block 130 (step 520), and the called subscriber is registered in the busy state in the call occupancy state (step 530).

On the other hand, the incoming mobile call control block 130 of FIG. 6 requests outgoing information from the originating mobile call control block 120 (step 640).

In the originating mobile call control block 120 of FIG. 2, the originating information is transmitted to the terminating mobile call control block 130 (step 270).

The outgoing mobile call control block 120 then processes outgoing to connect the call between the calling party and the called party (step 280).

Incoming mobile call control block 130 of FIG. 6 receives outgoing information from originating mobile call control block 120 (step 650) and processes the call of the called party (step 660).

As in the above step, the call of the called subscriber and the call of the calling subscriber can be connected.

As described above, the present invention improves call processing efficiency by allowing the visited subscriber management block 170 to manage the block managing the call state information of the subscriber and the visited subscriber information in the personal communication switch. Can be.
