Abstract

The present invention relates to an outgoing call announcement method for a calling subscriber in a personal communication exchange of a mobile communication method such as IS-651, IS-634, and European digital mobile telephone (GSM). In the process of processing a call from a subscriber who is unable to send a call without an announcement, the callable subscriber who sends a mobile call by releasing it immediately without an announcement service has a drawback that the call is interrupted or not connected without knowing the reason. If it is impossible to make a call in the personal communication switch, it is possible to improve the above-described drawback by connecting the call announcement announcement to the terminal of the calling mobile communication subscriber.

Description

How to Announce Out-of-Call Calls at a Personal Communication Exchange

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for disabling announcements in a personal communication switch, and more particularly, to an outgoing subscriber in a personal communication switch of a mobile communication method such as IS-651, IS-634, European digital service (GSM). It relates to a non-call announcement broadcast method.

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 from a 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 originating mobile call control block requests originating subscriber information by requesting originating subscriber information from a visitor location management block (VLR).

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 subscriber from the home location register via a 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 called terminal, the called terminal transmits a paging response to the base station, the base station controller, and the called 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 a call setup and makes a call between the called party and the calling party.

In the mobile call processing process of the above-described process, a callable subscriber who sends a mobile call by releasing it immediately without a guide broadcast service when a call request from a subscriber who cannot make a call is interrupted without knowing the reason.

The present invention has been made to solve the above-mentioned drawbacks of the prior art, and provides a method for disabling announcements in a personal communication exchange in which a mobile subscriber in an outgoing state accesses an announcement in a mobile communication switch network when a call is attempted. The purpose is to.

In order to achieve the above object, the present invention provides a plurality of base stations, a plurality of base station controllers and an outgoing mobile call control block for controlling an outgoing signal coming through a base station controller matching device; In a personal communication switch including an incoming mobile call control block that connects an originating subscriber and a called party by a control block, when the call request is made to the originating mobile call control block through a base station controller matching block, the originating mobile call control block A first step of making an outgoing subscriber information request to a visited subscriber management block which processes and processes the subscriber's data and receiving a response signal; The originating mobile call control block sends a call request request to the base station controller matching block and, if a setup message is received, making an originating busy registration to the visiting subscriber management block; After transmitting the call progress message and the radio channel allocation request message to the base station controller matching block and receiving the radio channel allocation notification message, the third step is a personal communication consisting of accessing the prohibition announcement and transmitting the message to the terminal of the calling subscriber. Provides a method for not transmitting announcements in the exchange.

Hereinafter, with reference to the accompanying drawings, it will be described in detail a preferred embodiment of the present invention.

1 is a block diagram for explaining an embodiment of a method for not transmitting announcements in a personal communication switch according to the present invention, wherein each of the first, ..., N-th base stations 10-1, ..., 10 -n) connects wirelessly with a personal communication subscriber in the area.

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. ) Calls from other exchanges and subscribers are switched to connect the calls and perform billing.

The exchange includes an Access Switching Subsystem (ASS) 160, an Interconnection Network Sub-system (INS), 190, and a Central Control Subsystem (CCS) (not shown). It is a schematic block diagram of an exchange, which is configured as shown) and exchanges information with each other and constitutes a single exchange.

The central control subsystem (not shown) is a subsystem that performs the overall operational and maintenance functions of the system.

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

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.

The visited subscriber management block 170 is located in the connection network control subsystem 190 of the personal communication switch and serves as a database for receiving and storing 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.

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

The home location register 30 communicates with a number of personal communication exchanges and sends subscriber information to each visitor location register (VLR) 170 inside each personal communication exchange 20. And receive.

An access switching processor-wireless (ASP-W) 140 is a processor that accesses a base station controller to accommodate a mobile subscriber.

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

The base station controller matching block 110 serves to convert a message coming from the base station controller 10 into a structure that can be used in the personal communication switch 20.

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 to request number translation.

In addition, the originating mobile call control block 120 requests the home location register 30 to obtain the location information of the called subscriber via the HLR matching block 150.

In addition, 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.

Meanwhile, the visited subscriber management block 170 transmits a paging request to the called mobile call control block 130 in the ASP-W 140 having the called subscriber.

Then, in the number translation block 180, if the recipient of the number translation results in the mobile call terminal, the originating mobile call control block 120 notifies the mobile call.

The HLR 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.7 and sends this SS NO.7 signal. It receives and transmits, and converts the internal signal of the personal communication exchange 20 into the SS NO.7 message so that the message is transmitted to the home location register.

And, the HLR matching block 150 serves to notify the home location register 30 access error when receiving the incoming location information request from the outgoing mobile call control block 120.

Referring to FIG. 2, a description will be made of a non-call announcement method in a personal communication exchange according to the present invention. The originating subscriber is a base station 10-1, ..., 10-n, a base station controller 10, a base station. A call request is made to the originating mobile call control block 120 via the controller matching block 110 (step 400).

The outgoing mobile call control block 120 makes a request for information of the outgoing subscriber to the visiting subscriber management block 170 (step 402).

The outgoing mobile call control block 120 waits until the visited subscriber management block 170 retrieves the information of the calling subscriber and transmits it to the outgoing mobile call control block 120 (step 404).

After waiting, the originating subscriber's information is received at the visiting subscriber management block 170 (step 406).

It is determined whether the received outgoing subscriber information is the outgoing subscriber information (step 408).

As a result of the determination, if the subscriber cannot transmit the call, a flag for not making a call is displayed and call processing is continued (step 410).

Accept the calling signal as it handles the call of general outgoing subscribers (step 412).

Then, the originating terminal receives notification of the originating signal through the base station controller matching block 210 to which the originating subscriber belongs.

Wait for a setup message to be received from the base station controller matching block 210 (step 414).

After the wait, the setup message is received from the base station controller matching block 210 (step 416).

When the setup message is received, the originating busy information is sent to the visiting subscriber management block 310 to register the caller's busy (step 418).

The originating signal mobile call control block 120 transmits a call progress message and a radio channel assignment request message to the base station controller matching block 110 (steps 420 and 422).

The outgoing mobile call control block 120 waits for a radio channel assignment notification message to be received (step 424).

The originating mobile call control block 120 receives the radio allocation notification from the base station controller matching block 110 after waiting for the radio allocation notification to come in (step 426).

When a radio channel assignment notification message is received, it is determined whether the originating subscriber's signal is indicated by the originating prohibition flag (step 428).

When the call prohibition flag is displayed, the announcement broadcast apparatus is accessed to access the call prohibition announcement broadcast to the subscriber-prohibited subscriber terminal (step 430).

If the subscriber who listened to this announcement broadcasts the call, the process ends (step 432).

If the originating prohibition flag is not displayed, the call processing is performed normally to connect the call with the called subscriber who the calling subscriber applied for (step 434).

As described above, the present invention has an effect that the subscriber can recognize the current situation by providing the outgoing announcement broadcast to the mobile communication subscriber when it is impossible to send from the personal communication exchange.
