摘要

慢跳频(SFH)特性允许GSM网络中的移动站将其工作频率从一个时隙改变到另一个时隙,导致每秒217跳。该技术可以应用于所有的通信和信令信道,除了广播公共控制信道(BCCH),该信道必须在固定频率上传输,以便根据GSM 05.08建议对相邻的蜂窝移动进行正确的RXLEV测量。根据J. Charles(1998)的研究,SFH改善了链路质量(主要针对移动缓慢的手机)并增加了网络容量。模拟和测量都揭示了这些有益的影响。

Synthesized frequency hopping in GSM networks: implementation and results
The slow frequency hopping (SFH) feature allows a mobile station in a GSM network to change its operation frequency from a time slot to another resulting in 217 hops per second. This technique can be applied on all traffic and signaling channels, except for the broadcast common control channel (BCCH), which must transmit on a fixed frequency in order to make possible correct RXLEV measurements for the neighbor cell mobiles based on Recommendation GSM 05.08. The SFH improves the link quality (mainly for slow moving mobiles) and increases the network capacity according to J. Charles (1998). Both simulation and measurements reveal these beneficial effects.
