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可以提供多种功能，例如呼叫转移、呼叫等待和呼叫拦截等。呼叫拦截是一种重要的功能，它可以在呼叫到达目标用户之前将其拦截并转移到其他用户或服务中心。

ISO/IEC 15053:2003标准规定了PISN中呼叫拦截的规范、功能模型和信息流。该标准定义了呼叫拦截的各种操作和消息，以及这些操作和消息之间的关系。此外，该标准还规定了呼叫拦截的各种参数和选项，以及这些参数和选项的取值范围和含义。

ISO/IEC 15053:2003标准还规定了PISN中呼叫拦截的交互方式。该标准要求PISN中的各个组件必须支持呼叫拦截功能，并且能够在不同的网络环境中进行交互。此外，该标准还规定了呼叫拦截的交互流程和消息格式，以确保不同的PISN组件之间能够正确地交换信息。

ISO/IEC 15053:2003标准还规定了呼叫拦截的安全性要求。该标准要求PISN中的呼叫拦截功能必须具有一定的安全性，以防止未经授权的用户进行恶意操作。此外，该标准还规定了呼叫拦截的安全机制和安全策略，以确保PISN中的呼叫拦截功能能够安全地运行。

总之，ISO/IEC 15053:2003标准是一项关于PISN中呼叫拦截的规范，它规定了呼叫拦截的各种操作和消息，以及这些操作和消息之间的关系。此外，该标准还规定了呼叫拦截的交互方式和安全性要求，以确保PISN中的呼叫拦截功能能够在不同的网络环境中进行交互，并且能够满足用户的需求。
