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中的各种设备需要进行交换信令以实现各种通信服务,而交换信令协议就是用于规定这些设备之间的通信协议的标准。

ISO/IEC 15050:2003标准是针对PISN中计费建议补充服务的交换信令协议的规范。计费建议补充服务是指在通话过程中,PISN设备向用户提供有关通话费用的建议信息,以便用户在通话结束后能够了解通话费用情况。该服务通常包括以下功能:

1. 提供通话费用的建议信息,如通话时间、通话费用等;
2. 允许用户在通话过程中查询通话费用;
3. 允许用户在通话结束后查询通话费用。

ISO/IEC 15050:2003标准规定了计费建议补充服务的信令流程、消息格式和参数等内容。具体来说,该标准规定了以下内容:

1. 计费建议补充服务的信令流程,包括建立、修改和释放计费建议信息的流程;
2. 计费建议补充服务的消息格式,包括建立、修改和释放计费建议信息的消息格式;
3. 计费建议补充服务的参数,包括建立、修改和释放计费建议信息时需要使用的参数。

通过ISO/IEC 15050:2003标准,不同厂商的PISN设备之间可以进行互操作,从而实现计费建议补充服务的功能。该标准的实施可以提高PISN设备之间的互操作性,促进PISN的发展和应用。
