Abstract

PURPOSE: A neighbor set search method of a wireless communication system is provided to quickly search a neighbor set by searching an entire active set and then the two neighbor sets. CONSTITUTION: A wireless communication system includes a terminal, a base station a base station controller and an exchange. A specific terminal connects to a specific base station(2). The base station judges whether it's time to search a neighbor set(4). If it's not time to search the neighbor set, the base station counts time(6). If it's time to search the neighbor set, the base station searches an entire active set and then searches two neighbor sets.

도 1은 본 발명에 따른 무선 통신 시스템의 네이버 세트 서치 방법을 실시하기 위한 무선 통신 시스템의 일 실시예를 나타낸 블록도로, 단말기(10), 기지국(12), 기지국 제어기(14), 및 교환기(16)로 구성된다.1 is a block diagram showing an embodiment of a wireless communication system for implementing a neighbor set search method of a wireless communication system according to the present invention. The terminal 10, the base station 12, the base station controller 14, and the exchanger ( 16).

동 도면에 있어서, 다수의 기지국 중에 예로, 특정 기지국(14)은 다수의 단말기 중에 예로, 특정 단말기(10)와 특정 채널을 통해 접속한다.In the figure, for example, among a plurality of base stations, the specific base station 14 is connected to, for example, a specific terminal 10 among a plurality of terminals through a specific channel.

다수의 기지국 제어기 중에 예로, 특정 기지국 제어기(14)는 상기기지국(14)과 접속한다.For example, among a plurality of base station controllers, a specific base station controller 14 connects with the base station 14.

교환기(16)는 상기 기지국 제어기(14)와 접속하여 상기 다수의 단말기간에 교환 기능을 수행한다.The exchange 16 is connected to the base station controller 14 to perform an exchange function between the plurality of terminals.

본 발명을 도 2를 참조하여 설명하면 다음과 같다.Hereinafter, the present invention will be described with reference to FIG. 2.

도 2는 본 발명에 따른 무선 통신 시스템의 네이버 세트 서치 방법의 일 실시예를 단계별로 나타낸 순서도이다.2 is a flowchart illustrating a step-by-step embodiment of a neighbor set search method of a wireless communication system according to the present invention.

먼저, 특정 단말기(10)가 특정 기지국(12)과 접속한다(단계 2).First, a specific terminal 10 connects with a specific base station 12 (step 2).

기지국(12)은 네이버 세트 서치 시간이 되었는지 여부를 판단한다(단계 4).The base station 12 determines whether the neighbor set search time is reached (step 4).

기지국(12)은 네이버 세트 서치 시간이 되지 않았을 경우 시간을 카운트한다(단계 6).The base station 12 counts the time when the neighbor set search time has not reached (step 6).

기지국(12)은 네이버 세트 서치 시간이 되었을 경우 액티브 세트를 전부 서치하고 네이버 세트를 2 개 서치한다(단계 8).When the neighbor set search time comes, the base station 12 searches all active sets and searches two neighbor sets (step 8).

이상에서 설명한 바와 같이 본 발명은, 다수의 단말기와 각각의 채널을 통해 각기 접속하는 기지국을 구비하는 무선 통신 시스템에 있어서, 액티브 세트를 전부 서치하고 네이버 세트를 2 개 찾도록 한다. 따라서, 네이버 세트를 빨리 찾을 수 있다.As described above, the present invention provides a wireless communication system including a plurality of terminals and a base station connected to each channel through respective channels, so that all active sets are searched and two neighbor sets are found. Therefore, the neighbor set can be found quickly.
