Apparatus, and associated method, for synchronizing operation of codecs operable pursuant to a communicaton session

摘要

Apparatus, and an associated method, for facilitating synchronization of the operational codec modes of communication stations which communicate pursuant to a communication session. Signaling is provided to indicate allowed AMR (adaptive multi rate) codec modes to optimize speech connections in a GSM/EDGE radio access network (GERAN). RTP messages are defined, such as defining new message types or new field extensions in RTP messages to identify the codec modes.
