Abstract

본 발명은 무선 채널을 이용하여 이동하면서 통신하는 셀룰라 폰에서, 특히 사용자가 서어비스를 제공받기 위해 셀룰라 폰을 등록한 홈네트워크(Home Network)가 아닌 다른 네트워크로 부터 서어비스를 제공받는 로우밍(Roaming)시 소정의 시간 간격으로 홈 네트워크의 서어비스 에리어에 진입하였는지의 여부를 검출하여 홈 네트워크를 통한 서어비스 모드로 진입하도록 한 것이다.The present invention relates to a cellular phone that communicates while moving by using a wireless channel, particularly when roaming provided with a service from a network other than a home network where a user registers a cellular phone to receive a service. The system detects whether the service area of the home network has been entered at a predetermined time interval and enters the service mode through the home network.

본 발명은 셀룰라 폰이 홈 네트워크가 아닌 임의의 네트워크를 로우밍하여 중계 서어비스를 실행하는 상황에서 홈 네트워크와의 수신전계 감도를 설정된 소정시간의 간격으로 연속적으로 검출하여 홈 네트워크를 통하여 중계 서어비스가 가능한 상태로 검출되면 로우밍으로 중계 서어비스를 제공하는 임의의 네트워크로 부터 홈 네트워크로 중계 서어비스의 주파수 채널을 변경하므로 셀룰라 폰의 사용에 불필요한 요금의 과지급을 방지하고, 홈 네트워크에서 제공되는 부가 서어비스를 제공받을 수 있어 사용에 신뢰성이 제공된다.In the present invention, when the cellular phone roams an arbitrary network other than the home network and executes the relay service, the relay service can be continuously detected through the home network by continuously detecting the received electric field sensitivity with the home network at a predetermined time interval. When a state is detected, the frequency channel of the relay service is changed from any network providing the relay service to the home network by roaming, thereby preventing overpayment of unnecessary charges for the use of the cellular phone and providing additional service provided by the home network. Can be provided to provide reliability in use.

Claims (1)

셀룰라 폰의 서어비스 제공방법에 있어서, 오프 상태에 있는 셀룰라 폰의 전원을 온 상태로 전환하면 중앙 제어수단은 수신전계의 감도를 통하여 서어비스를 제공하기 위한 네트워크를 검출하며 서어비스를 제공하기 위한 네트워크를 검출하며 서어비스를 제공하기 위해 검출된 네트워크가 셀룰라 폰 자신이 등록한 홈 네트워크인지의 여부를 판단하는 제1과정과, 상기 제1과정에서 홈 네트워크를 통한 서어비스의 제공으로 판단되면 홈 네트워크 서어비스 모드로 진입하고, 홈 네트워크를 통하여 서어비스를 제공할수 없는 상황으로 판단되면 주변의 임의의 네트워크를 통한 서어비스 가능여부를 검출하는 제2과정과, 상기 제2과정에서 임의의 네트워크를 통하여 서어비스의 제공이 가능하면 프로그램된 소정의 시간을 카운팅한후 임의의 네트워크를 통한 서어비스를 실행하며 서어비스가 제공되는 임의의 네트워크를 통한 서어비스의 상황을 검출하는 제3과정과, 상기 제3과정에서 서어비스가 제공되는 임의의 네트워크를 통한 서어비스 실행이 단절되면 상기 제1과정을 실행하여 서어비스를 제공하기 위한 네트워크를 검출하고, 서어비스가 제공되는 임의의 네트워크와의 상황이 양호하게 유지되면 상기 제3과정에서 카운팅시킨 소정의 시간이 경과하였는지의 여부를 판단하는 제4과정과, 상기 제4과정에서 설정된 소정의 시간이 경과하지 않았으면 상기 제3과정을 실행하여 임의의 네트워크를 통한 서어비스를 실행하고, 소정의 시간이 경과하였으면 홈 네트워크를 통한 서어비스 가능여부를 검출하는 제5과정 및, 상기 제5과정에서 홈 네트워크를 통하여 서어비스가 불가능하면 상기 설정된 시간을 재 카운팅하고, 홈 네트워크를 통한 서어비스가 가능하면 홈 네트워크를 통한 서어비스모드로 진입하는 제6과정을 포함하는 것을 특징으로 하는 셀룰라 폰의 로우밍시 홈 네트워크 스캐닝 방법.In the method for providing a service of a cellular phone, when the power of the cellular phone in the off state is switched on, the central control unit detects a network for providing a service through the sensitivity of the reception electric field, and detects a network for providing the service. And a first step of determining whether the detected network for providing the service is a home network registered by the cellular phone itself, and if it is determined that the service is provided through the home network in the first step, enter the home network service mode. If it is determined that the service can not be provided through the home network, the second process of detecting whether the service is available through any network nearby, and if the service can be provided through any network in the second process is programmed After counting a certain amount of time Executing a first service and detecting a situation of the service through any network provided with the service; and executing the first process when the execution of the service through any network provided with the service is disconnected in the third process A fourth step of detecting a network for providing a service and determining whether a predetermined time counted in the third step has elapsed if the situation with any network provided with the service remains good; A fifth process of executing a service through an arbitrary network by executing the third process if the predetermined time set in the fourth process has not elapsed, and detecting whether service is available through the home network after a predetermined time has elapsed; If the service is not possible through the home network in the fifth process, the set time Re-counting and, if possible, the seoeobiseu through the home network, the sixth process of the home network scanning method when Roaming in a cellular phone comprising the entering seoeobiseu mode over the home network. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
