| 摘 要： | 下一代网络（NGN）将融合多种异构无线接入网络。为了在满足QoS限制下,最大化网络收益,在对WLAN／CDMA等效带宽的研究基础上,提出一种基于SMDP（半马尔可夫决策规划）的最优的联合呼叫接入控制（JCAC）方案,方案考虑了WLAN和CDMA网络间的相互影响,并将网络连接的联合呼叫控制问题等效成一个半马尔可夫决策过程,仿真表明方案相对于离散时间的MDP和在MDP基础上的JCAC算法具有明显的优势。

| Abstract: | Next generation network aims to integrate heterogeneous wireless access networks.In order to maximize overall network revenue under the quality of service(QoS) constraints,an optimal joint call admission control scheme is proposed for the integrated WLAN/CDMA system.The interplay between WLAN and CDMA networks is taken into account in the designing of the system,and the joint call admission control problem is formulated as a semi-Markov decision process(SMDP).Numerical results show that the proposed scheme ... |
