Abstract

본발명은 이중의 채널관리모드를 가짐으로써 마이크로셀 구조에서도 고속이동중인 단말기와 통신이 가능하도록 무선통신 시스템의 마이크로셀룰라 운영방법에 관한 것으로서, 고속이동중인 단말기에게 마이크로셀을 쿨러스터링하여 동일한 무선채널을 사용함으로써 매크로셀로 동작하게 하고 단말기 주변의 마이크로셀들을 통하여 수신된 신호를 기초로 단말기의 위치를 추정하여 추정된 마이크로셀로 송신하고 매크로영역내에서 마이크로셀 사용의 패턴과 빈도에 따라 저속 및 고속여부를 판별하여 양모드로 핸드오프되도록 하고, 매크로영역내에서의 마이크로셀 사용의 패턴으로 다음의 근접 매크로영역을 예상, 이를 이용하여 핸드오프를 처리함으로써 많은 가입자 용량을 목표로 하는 개인통신시스템이나 무선구내 교환기 시스템에서 적은 반경의 마이크로셀구조를 통하여 고속이동중인 단말기와 통신이 가능하게 되는 것이다.The present invention relates to a method of operating a microcellular in a wireless communication system to enable communication with a fast moving terminal even in a microcell structure by having a dual channel management mode. By using, it operates as a macrocell, estimates the position of the terminal based on the signal received through the microcells around the terminal and transmits it to the estimated microcell. A personal communication system aiming at a large subscriber capacity by determining whether or not a high speed is to be handed off in both modes and predicting the next proximity macro area by the pattern of microcell usage in the macro area, and processing the handoff using it. Or in wireless branch exchange systems It is fast moving through complimented micro-cell structure which would allow the device to communicate with.

Claims

In the method of operating a micro cellular system of a wireless communication system, the microcell is operated as a macro cell using the same clustered radio channel, and is transmitted to a new microcell estimated based on a signal received through the microcells around the terminal. The same process is repeated each time the microcell is changed, and whether the low and high speeds are determined according to the pattern and the frequency of the microcell usage in the macro region is allowed to be handed off in both modes, and the pattern of the microcell usage in the macro region. A method of operating a micro cellular system of a wireless communication system for predicting the next proximity macro region and handing off using the same.

In the hand-off switching method of the wireless communication system, the macro mode operation routine L1 which executes the macro mode operation when the macro time is turned on when the call is set up, and the microcell may be changed after the macro mode operation routine L1 is executed. In this case, the first handoff processing routine 2 for handoff processing to the macro cell using the micro cell movement pattern and the macro time after execution of the macro operation routine L1 are determined. Is completed, the micro mode operation routine L3 operates in the micro mode when the micro time is turned on, and the micro time has elapsed when a handoff request is made after the micro mode operation routine L3 is executed. Check to clear the micro cell handoff when the macro time is completed. If hand-off switching method of a wireless communication system composed of a second hand-off processing routine (L4) for processing a handoff in macro mode.
