KR960028635A - Subscriber Location in Multiple Exchange Adjacent Areas - Google Patents

Abstract

According to the present invention, when a subscriber moves to an area where several exchanges are adjacent to each other, the location of subscribers in several adjacent areas of the switch for reducing the load in the wireless according to the location registration, increasing the reliability of the tracking of the subscriber and distributing the load on the wireline In particular, the method relates to a tracking method. When a subscriber requests a location registration request from a control station that manages a reference cell, the control station transmits a location updater including a unique terminal number and identification number of the subscriber and a cell unique number of the reference cell to which the subscriber has moved. The first process of transmitting a message, and the exchange receiving the location updater message in the first process is performed by using the previously stored terrain database and the cell unique number, based on the corresponding cell unique number. A second step of calculating whether there is a predetermined distance within the predetermined registration distance in the second step And if it is determined that there is an exchange adjacent to the subscriber station, a third process of combining the location updater message with the result calculated in the second process and transmitting the result to the control station. If a subscriber provides a location registration method and a routing method accordingly, when one subscriber moves to an adjacent area and performs distance-based location registration, one exchange registers the location with the HLR and the location information of the other exchange is transferred to the HLR. By using this information when storing and routing, it is possible to reduce the location registration load generated when the subscriber repeatedly moves between the exchanges in the border area and reduce the possibility of losing the subscriber at the exchange.

Claims (2)

In the cellular system, a location registration method for subscriber location tracking when a mobile station moves within an adjacent distance registration area in a cellular system, wherein the subscriber requests a location registration request from a control station that recommends a reference cell. A first step of transmitting a location update message including a terminal unique number and identification number of the terminal and a cell unique number of the reference cell to which the subscriber has moved; The switch receiving the location updater message in the first step of calculating the presence or absence of the switch within a predetermined registration distance based on the cell unique number based on the previously stored terrain database and the cell unique number; And a third step of combining the location updater message with the result calculated in the second step and transmitting the result to the control station when it is determined that there is an adjacent exchange in the predetermined registration distance area in the second step. A method for locating subscribers in adjacent areas of multiple exchanges. A routing method for tracking the location of a subscriber when a mobile station moves within a distance registration area adjacent to multiple exchanges in a cellular system, wherein the subscriber in charge of a call is requested when the subscriber in a general public network or another exchange requests a call. A first step of searching for a subscriber memory by searching for a subscriber memory; A second step of requesting routing information for the called party by sending a message requesting information about the called party to the control station when it is determined that there is no called party in the first step; Receiving the location request message, the control station searches the stored data of the exchange where the called party is registered, and if the called party is a subscriber whose location is registered in the adjacent area, the routing is routed to multiple exchanges with the unique numbers of the adjacent exchanges where the subscriber is registered. Transmitting a message requesting a request; Each exchange receiving the message, a fourth step of calculating and paging its cells at a predetermined registration distance of the boundary based on the cell unique number in the received message; A fifth step in which the exchange responding to the paging in the fourth process sends a response message to the control station in response to the location request including routing information; And a sixth process of the control station receiving the response message to send the response message according to the location request to the exchange requesting routing so that the originating exchange and the incoming exchange can route. Location of subscribers in the area adjacent to the exchange.
