标准摘要
[中文适用范围]： 本技术报告是系列出版物的一部分，提供了基于IP的企业通信的概述，涉及企业电信网络（CN，也称为企业网络），特别是下一代企业网络（NGCN）。该系列特别关注基于会话发起协议（SIP）[6] 的会话级通信，重点在于域间通信。这包括同一企业不同部分（在专用基础设施和/或托管）之间的通信、企业之间的通信以及企业与公共网络之间的通信。调查了关键技术问题，确定了该领域当前的标准化工作和差距，并陈述了一些要求。本技术报告提供了该主题的一般信息，定义了一些架构概念，确定了各种通信场景，并为支持其他提供特定主题更详细信息的出版物提供了框架。在发布本技术报告时，该系列中已发布了一份进一步的文件，主题为识别和路由 [3]。本技术报告的范围仅限于具有实时元素的通信，包括语音、视频、实时文本和即时消息。关于NGCN环境中移动性的更多详细信息，请参见ISO/IEC TR 26927 [2]。 [外文原描述]： ISO/IEC TR 12860:2009 is the first of a series of publications that explore IP-based enterprise communication involving Corporate telecommunication Networks (CNs) (also known as enterprise networks) and in particular Next Generation Corporate Networks (NGCN). The series particularly focuses on inter-domain communication, including communication between parts of the same enterprise, between enterprises and between enterprises and carriers. ISO/IEC TR 12860:2009 provides general information on the subject, defines some architectural concepts, identifies various communication scenarios, and provides a framework in support of other publications that provide greater detail on particular topics. The scope of ISO/IEC TR 12860:2009 is limited to communications with a real-time element, including voice, video, real-time text and instant messaging.
