摘要 从码分多址(CDMA)系统的特点出发,采用多维马尔可夫过程来分析多媒体业务共存时基于干扰水平的接入控制策略,得到在小区容量可变情况下的系统性能。文中考虑到切换用户的优先级以及不同类型用户的不同QoS要求,还在系统中设置了多级接入门限,从而实现在扩大系统容量的同时,又力求保证系统已有的链路质量,实现接入控制的目的。 This paper discusses CDMA system performance with multimedia services and analyzes interference-based admission control strategy with multi-dimensional Markov model. Moreover, considering priority of handover users and different QoS requirements, multi-level admission thresholds are set in system for different types of users, which can guarantee the quality of existed links and maximize the system capacity.
