摘要
IN CS-2(智能网能力集2)标准中的呼叫方控制能力使智能网能控制稳定通话状态下的2方或多方呼叫,通过论述国际标准中利用CPH(呼叫方控制)进行呼叫控制的模式和方法,以及实际应用中存在的问题和解决方法,提出了在现有网络及开发条件下的实现方案,并以同振业务为例进行了分析.分析结果表明,此种设计方案能够节省系统资源和提高业务的灵活性,是一种切实可行的方法.
The CPH(call party handling)proposed in ITU-T(international telecommunication union-telecommunication standardization sector) recommendation for IN(intelligent network) capability set 2 enables IN to influence two-party or multi-party calls,The method and model defined in CS-2(capability set 2) are analyzed in detail,some issues about CPH applications in the current network are discussed.A solution to CPH is proposed.And a multi-party call sample is carried out in this way.The result shows that this solution can save system resource and improve agility of service,and it is a userful method in practice.
