In this paper, we propose a wireless access mechanism for web traffic packets in an integrated wireless code-division multiple-access system that has both voice and web traffic. The proposed scheme is a medium-access control layer/link layer (MAC/LL) scheduling algorithm that consists of a two level control: admission control and packet scheduling. The admission control restricts the number of users in the system such that quality-of-service requirements [target signal-to-interference ratio (SIR) and delay] for both voice and web traffic can be met. The packet scheduling balances the system interference on a slot-by-slot basis such that the target SIRs can be achieved for all users (voice and web browsing sessions) with a higher scheduling priority for voice. Designing admission control for web users based on the average offered rate per session is difficult due to the high variations in the offered load generated by heavy tailed distributions for web traffic. To overcome this problem, we propose an admission control algorithm that adaptively estimates the aggregate average load based on load measurements using a sliding observation window.
