Abstract:

With code division multiple access 2000 1X evolution data optimized standard for wireless transmission, the session setup delay in internet protocol multimedia subsystem is analyzed by using mathematical analysis quantitatively. The produced transmission delay in date link layer is discussed used with radio link protocol, as well as the transmission delay produced by the retransmission scheme of upper layers. Analysis shows, the session setup delay becomes shorter when radio link protocol is used in date link layer, the datagram protocol is used in transport layer, and the session initiation protocol is used in application layer.

Key words: Internet protocol multimedia subsystem, session setup delay, radio link protocol
