私有综合服务网络(PISN)是一种专用的通信网络,用于在组织内部提供各种通信服务。PISN可以提供多种服务,如语音通信、数据传输、传真等。呼叫侵入补充服务是PISN中的一种补充服务,它允许用户在另一个用户正在通话时插入自己的呼叫。

ISO/IEC 14845:1996标准定义了呼叫侵入补充服务的功能和行为,以及与其他服务的交互作用。该标准规定了呼叫侵入补充服务的信息流和消息格式,以及服务的状态转换和错误处理。

呼叫侵入补充服务的实现需要支持以下功能:

1. 呼叫侵入请求:用户可以在另一个用户正在通话时请求插入自己的呼叫。

2. 呼叫侵入确认:被侵入用户可以确认是否允许插入呼叫。

3. 呼叫侵入拒绝:被侵入用户可以拒绝插入呼叫。

4. 呼叫侵入取消:用户可以取消已经发出的呼叫侵入请求。

5. 呼叫侵入完成:用户可以完成插入的呼叫并与被侵入用户通话。

6. 呼叫侵入挂断:用户可以挂断插入的呼叫。

呼叫侵入补充服务还需要与其他服务进行交互,如呼叫等待、呼叫转移等。该标准规定了呼叫侵入补充服务与其他服务的交互方式和行为。
