Multi-slot Channel Allocation for Priority Packet Transmission in the GPRS Network

Abstract

In the General Packet Radio Service (GPRS) network, data packets from services like mobility management and “push-to-talk” (PTT) are sensitive to delay. During the channel allocation process, the delay-sensitive packets should have higher priority than other packets. Previously priority queue and Uplink State Flag Channel Allocation (USFCA) have been used to reduce the transmission delay of priority packets. In this paper, we study the performance of channel allocation for priority packet in the GPRS network with multi-slot capability. The results show that the transmission delay of priority packet can be further reduced by assigning multiple channels to priority packet in addition to the use of priority queue and USFCA.
