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) 자동검사방법 Piel M & A in an instant digital cellular phones (PLMN) Automatic test methods

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. The present invention is a mobile telephone network in a digital cellular phone: is to automatically find the available PLMN of the present invention relates to (Public Land Mobile Network or less, 'PLMN' quot;) automatic inspection method, in particular forbidden PLMN.

종래 기술에서는 이동국(Mobile station)이 PLMN에 등록을 시도할 때, PLMN으로부터 등록을 거절당하면 그 PLMN을 금지된 PLMN 리스트에 등록한다. In the prior art when attempting to register on a PLMN mobile stations (Mobile station), and registers the forbidden PLMN list that PLMN danghamyeon reject the registration from the PLMN.

이후, 이동국이 자동 PLMN을 선택할 때 금지된 PLMN 리스트에 있는 것은 제외시키고, 나머지 PLMN중에서 등록을 시도하였다. After that, the mobile station is to exclude it in the list of forbidden PLMN when the PLMN selected automatically, the rest were trying to register in a PLMN.

이에 따른 종래의 이동국에서 PLMN에 등록하는 흐름을 제 1 도를 참조하여 설명하면 다음과 같다. This will be described with the flow registered in the PLMN in a conventional mobile station, see FIG. 1 in accordance with the following:

자동모드인 경우에 이동국 스위치를 온(ON) 후 이동국은 마지막으로 등록했던 PLMN에 등록을 시도하고, 만약 PLMN이 등록을 거절하면 이동국은 그 PLMN을 금지된 PLMN 리스트에 추가시킨다. After on (ON) the mobile station switches to the automatic mode when the mobile station attempts to register with the PLMN was last registered, and if a rejected PLMN registration the mobile station adds to the forbidden PLMN list that PLMN.

그리고 이동국은 사용가능한 PLMN중 하나를 선택하여 등록을 시도하고 등록이 성공할 때까지 3회 - 5회까지 반복하여 등록을 완료한다. And the mobile station attempts to register by selecting one of the available PLMN is used three times, until the registration is successful - to complete the registration, repeat up to 5 times.

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. Mode mobile station is registered in the PLMN in the above there is a manual mode and automatic mode, the first in manual mode, delete the PLMN in, Forbidden PLMN lists When performing If successfully registered, try the registered in PLMN previously banned .

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. But do not try to register to PLMN in the Forbidden PLMN list in the automatic mode, even if there is a current registration of the available PLMN PLMN in the Forbidden PLMN list station did not attempt to register.

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 wishes to register with the PLMN list of the forbidden PLMN list or could only do it in manual mode if the user wants to refresh (Refresh) to the forbidden PLMN list.

즉, 자동모드에서는 한번 금지된 PLMN 리스트에 등록되면 그것을 지우는 방법이 없는 문제점이 있었다. In other words, in the automatic mode when registered in the PLMN forbidden list once there is a problem there is no way to clear 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 forbidden PLMN automatic inspection method in a digital cellular phone to determine the registration possibility for the PLMN in the PLMN list of prohibited in the automatic mode in order to solve the above problems.

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 abovementioned objects is, if possible, is to register whether registration state determining process, and the registration state determining process for determining on the forbidden PLMN then on a mobile station in automatic mode register available PLMN It achieved the best success of the PLMN registered on the list as a successful registration process to register determines the predetermined number of iterations.

상기 과정에 의한 본 발명은 금지된 PLMN 리스트의 자동 리프레쉬 기능으로써 종래의 자동모드에서 할 수 없었던 금지된 PLMN의 등록여부를 판단하는 것이다. The present invention according to the process is to determine whether the properties of the forbidden PLMN can never be in a conventional automatic by automatic refresh function of the forbidden PLMN list mode.

사용자는 굳이 수동모드로 가지 않더라도 항상 최상의 사용가능한 PLMN을 알수 있음에 따라 가장 적합한 PLMN에 등록을 할 수가 있다. You can even dare to go to the manual mode is always registered in accordance with the most appropriate PLMN know that the best use possible PLMN.

일반적으로, 무선 이동통신 시스템(도시안됨)은 스위칭 시스템 블럭과 기지국 시스템 블럭으로 분할된다. In general, a wireless mobile communication system (not shown) is divided into a switching system block and the base station system block. 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. Base station system, a block includes one or more mobile stations (Mobile Station) to the subscriber uses for communicating voice and data messages over GSM specified signaling and traffic communication channels. 이동국은 이들 메시지를 송수신 기지국과 규정된 에어 인터페이스 프로토콜(air interface protocol)에 따른 하나 이상의 무선 주파수(RF) 통신 채널을 통해 통신한다. Mobile station communicates with one or more radio frequency (RF) communication channel in accordance with the air interface protocol (air interface protocol) defined with the base station transmit and receive these messages. 할당된 통신 셀을 서비스하는 송수신 기지국은 RF 채널을 통해 통신을 제공하는 무선 송수신기 및, 이동국 간에서의 통신 메시지를 처리하는 디지탈 신호 처리기를 포함한다. The base transceiver station to service an assigned communication cell includes a digital signal processor to process the communication messages in a wireless transceiver and a mobile station for providing communication between the through RF channel.

본 발명에 따른 상술한 이동국에서 PLMN에 등록하는 과정을 제 2 도를 참조하여 설명하면 다음과 같다. Referring to the process of registration a PLMN see FIG. 2 in the above-described mobile station according to the present invention.

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. If it is determined that you have to register for the PLMN in the PLMN list and on (ON) to switch on the mobile station, the ban in the case where the automatic mode find a PLMN that can be registered in PLMN in if the forbidden PLMN list using the available PLMN list and add books, try all the forbidden PLMN list, repeat 3-4 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. And the mobile station added to the list of forbidden PLMN when the registration of the mobile station attempts to register by selecting the best of the available PLMN PLMN fails, and repeated 6-7 times until the registration is successful.

이상과 같은 본 발명은 사용자가 굳이 수동모드로 가지 않더라도 자동모드에서 금지된 PLMN 리스트를 검사함으로써 최적의 금지된 PLMN 리스트를 유지할 수가 있다. The present invention as described above, even if the user is deliberately of the manual mode by checking a list of forbidden PLMN in the automatic mode can be maintained for optimal inhibition of the PLMN list.
