CDMA非标准增值业务来话呼叫模型的研究与实现

针对非标准增值业务在码分多址（CDMA）网络下发展受限的问题，以一卡多号业务为例，研究了非标准业务来话侧呼叫模型．结合基于业务控制点（SCP）的无应答呼叫前转模型，提出了一种基于基本呼叫状态模型（BCSM）变换的来话呼叫模型．实验结果表明，该呼叫模型对实现带有号码变换特征的非标准来话增值业务有效．

Research and Implementation of Terminating Call of Non-Standard Value-Added Service in CDMA Network

To solve the problem of restricted development of non standard value added services in code division multiple access network. A call model of terminating party of non standard service is analyzed with help of an example single international mobile subscriber identification number(IMSI) multiple mobile station international integrated services digital network numbers(MSISDN) service．Combined with call forwarding no answer service based on switching control point, a new call model of terminating party based on transform of basic call state model (BCSM) is presented．Experiments verify the validity of the proposed call model to implement non standard value added services with the transform attribute of called party number．
