私有综合服务网络(PISN)是一种专用的通信网络,用于在企业内部或组织内部提供各种通信服务,如电话、传真、数据通信等。PISN的交换信令协议是指在PISN中,各种通信设备之间进行通信所使用的协议。交换信令协议的标准化可以保证不同厂商的设备之间能够进行互操作,从而提高PISN的可靠性和互通性。

计费建议补充服务是PISN中的一种补充服务,它可以在通话过程中向用户提供当前通话的计费信息,以便用户了解通话费用。ISO/IEC 15050:2003标准规定了计费建议补充服务的功能、信令流程、消息格式和参数等内容,以便不同厂商的PISN设备之间能够进行互操作。

ISO/IEC 15050:2003标准规定了计费建议补充服务的以下功能:

1. 提供当前通话的计费信息,包括通话时间、通话费用等;
2. 允许用户在通话过程中查询当前通话的计费信息;
3. 允许用户在通话过程中设置计费限制,以避免超出预算;
4. 允许用户在通话结束后查询通话的计费信息。

ISO/IEC 15050:2003标准规定了计费建议补充服务的信令流程:

1. 用户发起通话请求;
2. PISN设备向用户发送计费建议信息;
3. 用户确认计费建议信息;
4. 通话开始;
5. PISN设备向用户发送计费信息;
6. 用户查询计费信息或设置计费限制;
7. 通话结束;
8. 用户查询通话的计费信息。

ISO/IEC 15050:2003标准规定了计费建议补充服务的消息格式和参数,以便不同厂商的PISN设备之间能够进行互操作。消息格式和参数包括计费建议信息、计费信息、计费限制信息等。

总之,ISO/IEC 15050:2003标准规定了PISN中计费建议补充服务的功能、信令流程、消息格式和参数等内容,以便不同厂商的PISN设备之间能够进行互操作,从而提高PISN的可靠性和互通性。
