KR980007001A - Fixed Subscriber Call Control Method in Digital Cellular Mobile Switching System - Google Patents

Abstract

The present invention relates to a fixed subscriber's call control method in a mobile telephone switch in a digital cellular mobile communication network. Although a fixed subscriber is not currently accommodated in an analog mobile communication network, a test fixed subscriber for system management must be accommodated, and thus a CDMA scheme is used. Fixed subscribers must be accommodated in the digital mobile communication network. Accordingly, the present invention treats fixed subscriber information as mobile subscriber information and stores it in the subscriber's home location register, and requests fixed subscriber information at the visitor location register when the fixed subscriber first sends or receives a call request. If the subscriber information is not stored in the register, it receives the information from the subscriber location register and stores it in the database, and the fixed subscriber information is configured like the mobile subscriber information. Except for processing and supplementary service processing, it implements the same flow as the mobile subscriber call control processing, but the dialing tone is heard at the exchange, and in the case of the mobile subscriber, the subscriber performs a truncation process even if the other subscriber disconnects during the call. Fixed subscribers Hearing the beeper so that the user can receive the service without feeling the difference from using the existing wired network.

Claims (3)

A fixed subscriber call control method in a mobile telephone exchange in a CDMA digital cellular mobile communication network having a mobile terminal, a base station, a control station, a mobile telephone exchange, and a subscriber location register, wherein the fixed subscriber housed in the mobile telephone exchange originates a call. The first process of performing the incoming call processing according to the type of the called subscriber by analyzing the called party's number received from the calling fixed subscriber, and when the calling fixed subscriber or the called subscriber is disconnected after performing the first step. And a second process of performing a truncation process according to the present invention. 2. The method of claim 1, wherein the first process requests the originating fixed subscriber's information to the visitor location register when the fixed subscriber housed in the mobile telephone exchange originates, and requests the subscriber's home location register if the subscriber information is not on the visitor location register. After receiving the corresponding information, the information is stored in the visitor location register, and then the fixed fixed subscriber is able to determine whether the call is possible and if the call is possible, the first to first step and the dial tone are heard. When receiving the subscriber's number from the calling subscriber, the receiving subscriber's number is analyzed and if the number is from another network or if the number is registered with another mobile telephone switch in the same mobile network, the fixed outgoing call is processed. If the location is registered in the mobile telephone exchange, such as receiving incoming subscriber information, Steps 1 and 2 in which the subscriber determines that the incoming call is possible, and if the incoming subscriber is registered in the mobile telephone exchange such as the calling subscriber in step 1-2, and the incoming call is possible, the type of the called subscriber is investigated. If the incoming subscriber is a fixed subscriber, steps 1-3, and if the called subscriber is a mobile subscriber in step 1-3, When a page request is made to the control station that has registered the location, and a page response is received from the control station, the call is connected to the general call path between the calling party and the called party, and the call station is requested to connect the calling signal to the controlling station that processes the called party. Steps 1-4 for returning the ring tone to the subscriber, and if the called subscriber who is listening to the call signal in step 1-4 responds, However, when the fixed outgoing outgoing process starts after steps 1-5 and the outgoing fixed subscriber and the incoming mobile subscriber make a call, the routing process is occupied by occupying the outgoing line, and the incoming subscriber is connected to the destination exchange. After sending the number, connect the general call path between the calling subscriber and the outgoing mooring, and when the incoming information is received, the call signal is received by steps 1-6 and the first 1-6 waiting for the incoming response after storing the incoming information. When the called subscriber of the other country answers, the calling fixed subscriber and the called subscriber of the other country call in steps 1-7, and when the called subscriber is determined to be a fixed subscriber after performing the steps 1-3, the called subscriber is analyzed through the called number analysis. Finds the line and, if the called party is idle, connects the public line between the calling party and the called party, makes a ring tone to the calling party and calls to the called party. After the signal is connected, when the fixed called party listening to the call signal is answered by steps 1-8 waiting for a response from the called party, and when the called party answers the call signal according to the steps 1-8, the call tone and call signal are cut off, and then the calling fixed subscriber is disconnected. The fixed subscriber call control method of the digital cellular mobile telephone switch, characterized in that consisting of the first to nine steps of the incoming fixed subscriber. 2. The method of claim 1, wherein the second process comprises steps 2-1 of performing a truncation process when the calling fixed subscriber is disconnected during a call after performing the first process, and after performing the first process, A fixed subscriber call control method in a digital cellular mobile telephone switch, characterized in that the step 2-2 of performing a truncation process when a mobile subscriber, a fixed subscriber of its own station, or a destination subscriber of another country disconnects.
