随着 5G 和 5G-Advanced 网络的演进发展,多媒体实时通信业务正在向超清化、交互式、沉浸式及开放性趋势发展,对现有基于IP多媒体子系统 (IP multimedia sub system,IMS网络)的多媒体实时通信系统提出了架构和网络能力方面的增强需求。对实时多媒体通信系统架构的增强技术进行了研究和探讨,通过引入基于IMS网络架构的交互式通信通道技术,提出了服务化统一媒体面和三方标识认证的架构及流程,更好地满足个人和行业用户多样化、沉浸式多媒体实时通信体验需求。同时提出了一种多媒体实时通信网络新架构,对多媒体实时通信的控制面架构进行演进重构,提供更为简化、灵活和开放的会话控制、会话路由、媒体面管理、业务调用、业务组合机制。
With the development of 5G and 5G-Advanced network
multimedia real time communications were migrating towards the trends of super high definition
enhanced interaction
immersion and openness
which requires enhancements on the architecture and capability of legacy IMS based multimedia real time communication system.The enhancement technologies of the multimedia real time communication system was studied and accordingly was proposed.By defining an“IMS network” based interactive data channel
a service-based unified media control architecture and procedures of third party identity on top of IMS network were proposed
to better fulfill the diverse and immersive service experiences for personal and vertical users.A new design of the real time communication system architecture was proposed
which enabled simpler
more flexible and more open mechanisms of the session control
session routing
media management
service invoking and combination.
