Resource Allocation for Interactive Traffic Class over Gprs

The General Packet Radio Service (GPRS) is a new bearer service for GSM that greatly simplify wireless access to packet data networks, e.g., to the Internet, to the corporate LAN or to the mobile portals. It applies a packet radio standard to transfer user data packets in a well-organized way between Mobile Stations (MS) and external packet data networks. The introduction of guaranteed performance services in GPRS networks requires detailed studies of the resource allocation and service integration issue. This paper proposes some different schemes of allocating the physical channels to mobile stations. We consider the integration of voice and data over Time Division Multiple Access wireless cellular networks. We describe different radio resource allocation algorithms, and describe their similarities and differences in the context of GSM and GPRS networks. However these algorithms can be used for diversified types of wireless networks. In this paper we consider the interactive best effort traffic class as one of the most important traffic classes in GPRS.
