Summary:
|
Data channel is based on WebRTC data channel protocol stack which is defined as the framework to carry media data between web browsers as defined in RFC8831. It is adapted to be used by new procedures in 3GPP TS R16 26.114 and through minor extensions to existing call procedures in 3GPP R17 TS 24.229.
Data Channel enables adding real-time communication between people and things, alongside the current HD voice and video calling services. With the application of data channel technology, the IMS network can make use of data channel functionality to diversify new services and widen business opportunities. To fully utilize Data Channel advantages, further research and analysis on the signalling architecture of data channel enhanced IMS network is quite essential. And in ITU, there’s no dedicated research or standard on data channel based IMS network yet.
On the basis of research on IMS network as well as data channel, this Recommendation approaches the issues of requirement, framework and interfaces for signalling architecture of data channel enhanced IMS network. This Recommendation presents the requirements of signalling architecture of data channel enhanced IMS network, specifies the framework of data channel based IMS network, and specifies the interfaces between data channel elements to IMS elements.
