Resource allocation for handoffs in integrated wireless cellular networks
Wei Li, Hang Chen, Qing-An Zeng, Dharma Prakash Agrawal · 2004
In this paper, we propose and analyze a handoff scheme with channel borrowing in integrated wireless mobile networks. The channels in each cell are divided into two parts and pre-allocated for real-time and non-real-time services. In order to increase the channel utilization, one type of service is allowed to borrow channels from the other under certain conditions. We take advantage of the delay insensitivity of non-real-time service calls by allowing real-time service calls to preempt non-real-time service calls. The proposed scheme maximizes the resource utilization while keeping certain quality of service (QoS) level for one type of service regardless of the traffic load of the other.
