Abstract :
This paper proposes a new class of adaptive handoff channel management schemes. The proposed schemes aim at reducing the handoff failure probability below a predefined threshold by adjusting a channel sharing ratio between new and handoff calls. In a resource limited environment, however, reducing the handoff failure probability increases the new call blocking probability. The proposed schemes provide a flexible method to control the desired level of QoS and strike a balance between the “minimal” handoff failure probability and the “minimal” new call blocking probability by controlling the new call admission rate. This approach alleviates the channel assignment scheme from a tight dependency on the underlying traffic model and reflects the dynamically changing system load environment
