RTP复用的优点
RTP复用技术基于3GPP TS 29.414实现:
l RTP Multiplexing Solution:
•
Multiplex a number of voice data packets to one (max packet lengthis 1500 bytes).
•
Supported by MGW (according 3GPP TS 29.414), no special requirementto router.
l Benefits:
•
Save IP transmission cost (up to 60% bandwidth saved for AMR 12.2k,e.g.).
•
Reduce the process load of routers because of less packet number.
