This document defines a profile for IMS data channel services over IMS by listing a number of E-UTRAN\/NG-RAN, EPC\/5GC, IMS core and UE features and procedures that are considered essential to launch interoperable end to end services. The defined profile is compliant with and based on:<\/p>\n

    \n
  1. 3GPP\/GSMA specifications related to voice, video and data channel services over IMS.<\/li>\n
  2. IETF specifications related to the WebRTC data channels and the general WebRTC protocol.<\/li>\n
  3. Ecma International<\/a> ECMAScript standard supporting interoperability and the client site scripting for the W3C defined WebRTC 1.0 [20] data channel API component required to implement data channel media type.<\/li>\n<\/ol>\n

    The scope of this profile includes both the User to Network Interface (UNI) and Network to Network Interface (NNI),that is the interfaces between the User Equipment and the network as well as between the networks themselves. The NNI interface in this PRD is to be used in conjunction with GSMA PRD IR.95 [72]. The document also profiles DCMTSI client in terminal capabilities and the selected aspects of JavaScript API.<\/p>\n
