Abstract

PURPOSE: A method for automatically checking a prohibited PLMN(Public Land Mobile Network) in a digital cellular phone is provided to maintain an optimum prohibited PLMN by checking the prohibited PLMN list in an automatic mode. CONSTITUTION: An MS(Mobile Station) is turned on in an automatic mode, and it is judged whether it is possible to register prohibited PLMNs. If it is possible to register prohibited PLMNs, it is repeatedly judged whether the registration of an optimum PLMN succeeds in a usable PLMN list. If the registration of the optimum PLMN succeeds in the usable PLMN list, the PLMN is registered.

Description

디지탈 셀룰라폰에서의 금시된 피엘엠엔(PLMN) 자동검사방법Automated Test of PLMN in Digital Cell Phones

본 발명은 디지탈 셀룰라폰에서의 이동전화망(Public Land Mobile Network: 이하, 'PLMN'이라 칭함) 자동검사방법에 관한 것으로, 특히 금지된 PLMN의 사용가능한 PLMN을 자동으로 찾기 위한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a public land mobile network (hereinafter referred to as 'PLMN') automatic inspection method in digital cellular phones, and particularly to automatically find available PLMNs of prohibited PLMNs.

종래 기술에서는 이동국(Mobile station)이 PLMN에 등록을 시도할 때, PLMN으로부터 등록을 거절당하면 그 PLMN을 금지된 PLMN 리스트에 등록한다.In the prior art, when a mobile station attempts to register with a PLMN, if the registration is rejected by the PLMN, the PLMN is registered in the prohibited PLMN list.

이후, 이동국이 자동 PLMN을 선택할 때 금지된 PLMN 리스트에 있는 것은 제외시키고, 나머지 PLMN중에서 등록을 시도하였다.Thereafter, when the mobile station selects an automatic PLMN, it attempts to register among the remaining PLMNs except for being on the list of prohibited PLMNs.

이에 따른 종래의 이동국에서 PLMN에 등록하는 흐름을 제 1 도를 참조하여 설명하면 다음과 같다.Accordingly, the flow of registering with the PLMN in the conventional mobile station will be described with reference to FIG.

자동모드인 경우에 이동국 스위치를 온(ON) 후 이동국은 마지막으로 등록했던 PLMN에 등록을 시도하고, 만약 PLMN이 등록을 거절하면 이동국은 그 PLMN을 금지된 PLMN 리스트에 추가시킨다.In the automatic mode, after turning on the mobile station switch, the mobile station attempts to register with the last registered PLMN, and if the PLMN rejects the registration, the mobile station adds the PLMN to the list of prohibited PLMNs.

그리고 이동국은 사용가능한 PLMN중 하나를 선택하여 등록을 시도하고 등록이 성공할 때까지 3회 - 5회까지 반복하여 등록을 완료한다.The mobile station then selects one of the available PLMNs to attempt registration and repeats registration three to five times until registration is successful.

상기에서 이동국이 PLMN에 등록하는 모드는 수동모드와 자동모드가 있는데, 먼저 수동모드에서는 이전 금지된 PLMN에도 등록을 시도하여 만약 성공적으로 등록을 수행하게 되면, 금지된 PLMN 리스트에서 그 PLMN을 삭제한다.In the above mode, the mobile station registers with the PLMN. There are a manual mode and an automatic mode. In the manual mode, the mobile station first attempts to register a previously forbidden PLMN. .

그러나 자동모드에서는 금지된 PLMN 리스트에 있는 PLMN으로 등록을 시도하지 않으므로 금지된 PLMN 리스트에 있는 PLMN중 현재 등록 가능한 PLMN이 있다 하더라도 이동국은 등록을 시도하지 않았다.However, in the automatic mode, the mobile station does not attempt to register even if there are currently PLMNs that can be registered among the PLMNs in the prohibited PLMN list.

따라서, 만약 사용자가 금지된 PLMN 리스트에 있는 PLMN 리스트에 등록을 하고자 할 경우 또는 사용자가 금지된 PLMN 리스트를 리프레쉬(Refresh) 하고자 할 경우에 수동모드에서만 그것을 할 수 있었다.Therefore, if the user wants to register to the PLMN list in the banned PLMN list or the user wants to refresh the banned PLMN list, it can only do it in manual mode.

즉, 자동모드에서는 한번 금지된 PLMN 리스트에 등록되면 그것을 지우는 방법이 없는 문제점이 있었다.That is, in the automatic mode, once registered in the prohibited PLMN list, there is a problem that there is no way to delete it.

본 발명은 상기 문제점을 해결하기 위해 자동모드에서의 금지된 PLMN 리스트에 있는 PLMN에 대해 등록가능성을 판별하기 위한 디지탈 셀룰라폰에서의 금지된 PLMN 자동검사방법을 제공하는데 그 목적이 있다.An object of the present invention is to provide a method for automatically checking a prohibited PLMN in a digital cellular phone for determining the possibility of registration for a PLMN in a prohibited PLMN list in an automatic mode.

상기 목적을 달성하기 위한 본 발명의 방법은, 자동모드에서 이동국을 온 시킨 후 금지된 PLMN들에 대해 등록가능한지를 판단하는 등록여부판단과정과, 상기등록여부판단과정으로 등록이 가능할 경우 사용가능한 PLMN 리스트에서 최상의 PLMN의 등록성공여부를 소정 횟수 반복 판단하여 등록하는 등록성공과정으로 이루어진다.The method of the present invention for achieving the above object is a registration decision process for determining whether to register for the prohibited PLMNs after turning on the mobile station in the automatic mode, and PLMN available when registration is possible by the registration decision process The registration success process is performed by repeatedly determining the registration success or failure of the best PLMN in the list.

상기 과정에 의한 본 발명은 금지된 PLMN 리스트의 자동 리프레쉬 기능으로써 종래의 자동모드에서 할 수 없었던 금지된 PLMN의 등록여부를 판단하는 것이다.According to the present invention by the above process, the automatic refresh function of the forbidden PLMN list is to determine whether or not to register the forbidden PLMN which could not be performed in the conventional automatic mode.

사용자는 굳이 수동모드로 가지 않더라도 항상 최상의 사용가능한 PLMN을 알수 있음에 따라 가장 적합한 PLMN에 등록을 할 수가 있다.The user can always register with the most suitable PLMN even if he does not go into manual mode because he always knows the best available PLMN.

일반적으로, 무선 이동통신 시스템(도시안됨)은 스위칭 시스템 블럭과 기지국 시스템 블럭으로 분할된다. 기지국 시스템 블럭은 음성 및 데이타 메시지를 GSM 지정 시그날링 및 트래픽 통신 채널을 통해 통신하기 위해 가입자가 사용하는 하나 이상의 이동국(Mobile Station)을 포함한다. 이동국은 이들 메시지를 송수신 기지국과 규정된 에어 인터페이스 프로토콜(air interface protocol)에 따른 하나 이상의 무선 주파수(RF) 통신 채널을 통해 통신한다. 할당된 통신 셀을 서비스하는 송수신 기지국은 RF 채널을 통해 통신을 제공하는 무선 송수신기 및, 이동국 간에서의 통신 메시지를 처리하는 디지탈 신호 처리기를 포함한다.In general, a wireless mobile communication system (not shown) is divided into a switching system block and a base station system block. The base station system block includes one or more mobile stations that subscribers use to communicate voice and data messages over GSM directed signaling and traffic communication channels. The mobile station communicates these messages with one base station over one or more radio frequency (RF) communication channels in accordance with a defined air interface protocol. A base transceiver station serving an allocated communication cell includes a radio transceiver for providing communication over an RF channel and a digital signal processor for processing communication messages between mobile stations.

본 발명에 따른 상술한 이동국에서 PLMN에 등록하는 과정을 제 2 도를 참조하여 설명하면 다음과 같다.The process of registering with the PLMN in the above-described mobile station according to the present invention will be described with reference to FIG.

자동모드인 경우에 이동국의 스위치를 온(ON) 후, 금지된 PLMN 리스트에 있는 PLMN들에 대해 등록을 할 수 있는지를 판단하여 만약 금지된 PLMN 리스트에 있는 PLMN중 등록할 수 있는 PLMN을 발견하면 사용가능한 PLMN 리스트에 추가시키고서, 3-4회 반복하여 금지된 PLMN 리스트를 모두 시험해 본다.In the automatic mode, after switching on the mobile station, it is determined whether to register the PLMNs in the prohibited PLMN list, and if it finds a PLMN that can be registered among the PLMNs in the prohibited PLMN list. Add it to the list of available PLMNs, and then repeat all of the forbidden PLMN lists three to four times.

그리고 이동국은 상기 사용가능한 PLMN중 최상의 PLMN을 선택하여 등록을 시도하여 이동국의 등록이 실패할 경우 금지된 PLMN 리스트에 추가하고, 등록이 성공할 때 까지 6-7회 반복한다.The mobile station selects the best PLMN among the available PLMNs, attempts registration, adds to the list of prohibited PLMNs when registration of the mobile station fails, and repeats 6-7 times until registration is successful.

이상과 같은 본 발명은 사용자가 굳이 수동모드로 가지 않더라도 자동모드에서 금지된 PLMN 리스트를 검사함으로써 최적의 금지된 PLMN 리스트를 유지할 수가 있다.As described above, the present invention can maintain an optimal prohibited PLMN list by checking the prohibited PLMN list in the automatic mode even if the user does not go to the manual mode.

제 2 도는 본 발명 디지탈 셀룰라폰에서의 금지된 피엘엠엔 자동검사과정을 나타낸 흐름도.2 is a flow chart showing a forbidden PLM automatic inspection process in the present invention digital cell phone.
