Abstract -- Third generation wireless networks carry traffic from het-
erogeneous sources such as voice, data, video or multimedia with a speci-
fied quality of service. Efficient traffic management schemes should be de-
veloped to provide seamless access to the wireless network. In this paper,
we propose a novel cell switching (e.g., packet handoff) scheme to support
QoS guarantee for downlink in EGPRS (Enhanced General Packet Ra-
dio Service) network. We define the new packets and handoff packets for
each type of traffic and devise a new prioritization scheme at the buffer
of the base station. We present the procedure to find the optimal thresh-
olds satisfying the QoS requirements. Using the ON-OFF approximation
method for the aggregate traffic, we compute the packet loss probability
and the packet waiting time. The performance of the proposed scheme is
evaluated by simulations and numerical analysis in terms of packet loss
