Soft handoff method considering capacity increase of code division multiple access system

摘要

The present invention relates to a code division multiple access (CDMA) mobile communication system, and more particularly, to a code division multiple access (CDMA) mobile communication system capable of efficiently using radio resources using a characteristic of communicating with two or more base stations in soft handoff, And a soft handoff method considering a capacity increase of the system.;Generally, in CDMA mobile communication systems, soft handoff is used to improve the quality of a handoff call. However, since soft handoff is performed simultaneously with two or more base stations, the use of radio resources increases, which may lead to a decrease in system capacity.;Accordingly, the present invention uses a soft handoff characteristic for selecting a good signal from two or more base stations, and suspends the execution of the handoff to accommodate more subscribers when the strength of the handoff request is weak. On the other hand, we propose a soft handoff method that considers the system capacity to maintain a good call quality by performing a handoff as soon as possible when the strength of the radio wave is strong.
