Access scheme for integrated voice/data transmissions over common packet channel in 3GPP

In this letter, we propose a flexible channel assignment scheme using preemption as an access method for integrated voice/data transmissions over common packet channel (CPCH) in 3GPP. We analyze the proposed scheme and compare the performance of the proposed scheme with the performance of the basic, channel monitoring, and channel assignment schemes in view of the voice packet dropping probability and the average delay of data packet.
