本ETSI指南的范围包括允许智能网络和互联网协议互通的功能标准化。涵盖:-互联网协议用户代理（UA）功能到服务控制网关（SCG）功能的信令要求；-支持SCG功能和其他功能实体之间的互联网协议的信令要求-SCG功能与其他功能实体之间特定服务的信令要求；-用于在电路交换网络（包括实体）中部署IP的体系结构； -使用在用控制点（SCP）作为平台来支持IP/在用网守功能；-安全方面也需要解决。

The scope of this ETSI Guide is to cover the standardisation of functions to allow interworking of Intelligent networks and Internet protocols. Covering: - Signalling requirements on the Internet protocols User Agent (UA) function to Service Control Gateway (SCG) function; - Signalling requirements to support Internet protocols between the SCG function and the other IN functional entities; -Signalling requirements to specific services between the SCG function and the other IN functional entities; - Architectures for the deployment of IP in the circuit Switched Network, including IN entities; - Use of IN Service Control Points (SCP) as platforms to support IP/IN Gatekeeper functions; - Security aspects also need to be addressed.
