文中提出一种新的CDMA系统中多业务接入控制算法。为了提高系统容量,在传统容量干扰受限的CDMA系统接入控制算法的基础上,考虑各种业务的激活因子,计算出系统接入呼叫用户后各个业务的中断概率,根据其中断概率是否满足QoS要求判断业务是否接入。仿真结果表明:所提算法的各种业务的阻塞概率明显低于传统算法,并且系统获得的性能改善随着某些业务呼叫强度的增加而下降,从而证明了所提算法在系统容量上的优势。
In this paper, a new multi-service access control algorithm in CDMA system is proposed. In order to improve the system capacity, based on the access control algorithm of CDMA system with limited capacity interference, the activation probability of various services is considered, and the outage probability of each service after the system accesses the calling user is calculated. According to whether the outage probability is satisfied QoS requirements determine whether the business access. The simulation results show that the blocking probability of various services in the proposed algorithm is significantly lower than that of the traditional algorithm, and the performance improvement obtained by the system declines with the increase of some business calls, which proves the advantages of the proposed algorithm in system capacity .
