An advanced channel access scheme for integrated multimedia services with various bit rates in CDMA networks
Kyung Su Park, Dong Ho Cho · IEEE Communications Letters · 1999
For efficient code sharing among users, a wireless medium access control (MAC) protocol for CDMA networks is proposed, which supports connection-oriented, as well as connectionless, services and provides the various bit rates needed for the integrated multimedia services. The proposed MAC protocol allows mobile terminals to use multiple slots and spreading codes based on contention and reservation. Optimum frequency resources are allocated to the connection-oriented and connectionless services with various bit rates. Waiting and response times in the first contention are reduced, and the overall mean delay time is typically minimized in the case of connectionless bulky traffic.
