scope:

This Recommendation describes the support of real-time transport protocol (RTP) stream pause and resume functionality as defined by [IETF RFC 7728] on ITU-T H.248 controlled gateways. It describes the mapping of call control session description protocol (SDP) related to pause/resume to ITU-T H.248 SDP and vice versa. It also contains a package that allows several different implementation types to be supported. This allows the media gateway (MG) to operate in an autonomous manner by receiving, making pause/resume decisions and sending real-time control protocol (RTCP) level pause/resume messages with minimal media gateway controller (MGC) involvement. An MGC controlled configuration is also supported whereby the reception of pause/request requests/responses is indicated to the MGC for it to make decisions and determine a response. It also allows the MGC to initiate pause/resume requests.

The use of pause codec control messages (CCMs) as defined by [IETF RFC 7728] and temporary maximum media stream bit rate requests (TMMBR) as defined by [IETF RFC 5104] to pause and resume RTP media streams are both supported.

It also contains considerations related to the support of RTP stream pause and resume in ITU-T H.248 controlled gateways.

This Recommendation also details the relationship to other existing ITU-T H.248.x sub-series Recommendations where pause/resume functions are supported.
