Abstract :
The general packet radio service (GPRS) offers performance guaranteed packet data services to mobile users. This paper presents a guaranteed quality-of-service (QoS) provisioning scheme over GPRS wireless mobile links by proposing a guaranteed QoS media access control (GQ-MAC) protocol and an accompanying prioritized handoff call admission control (PH-CAC) protocol to maintain QoS guarantees under the effect of mobile handoffs. The GQ-MAC protocol supports bounded channel access delay for delay-sensitive traffic, bounded packet loss probability for loss-sensitive traffic, and dynamic adaptive resource allocation for bursty traffic. The PH-CAC protocol provides prioritized admission by differentiating handoff requests with different higher admission priorities over new calls via a multiple guard channel scheme.
