Gateway Control Protocol: Media resource control enhancement packages
|Publication Date:||1 April 2016|
[b-IETF RFC 4313] outlines the needs and requirements for a protocol to control the distributed media processing resources, including automatic speech recognition (ASR), speaker identification/speak
These media resources may reside in a decomposed media gateway (MG) utilising [ITU-T H.248.1] as a media gateway control protocol. In such a scenario there is an interworking between MRCP and ITU-T H.248.
This Recommendation provides an analysis of the interaction between the various MRCP methods, headers and events and the ITU-T H.248-series of Recommendations. It does not provide a complete interworking specification in terms of call flows due to the complexity of scenarios arising from media resource control. Many of the functions can be achieved through the mechanisms defined in the existing ITU-T H.248-Series of Recommendations (i.e., [ITU-T H.248.9] and [ITU-T H.248.66]). However, some functions require the definition of additional ITU-T H.248 packages. This Recommendation details these enhancements.
