The Recommendation ITU-T Q.3064 provides the signalling architecture of NICE in support of awareness capabilities based on Recommendation ITU-T Y.2301, ITU-T Y.2302 and ITU-T Y.2303. Based on the functional architecture and the awareness functions of NICE, this recommendation specifies the mapping of reference points to interfaces in the signalling architecture of NICE especially in support of awareness capabilities. And it also provides the signalling requirements and protocols used for interfaces and the signalling procedures of NICE in support of awareness capabilities.
