Abstract :
Channel borrowing without locking (CBWL) allows real-time borrowing of channels from adjacent cells without channel locking in co-channel cells. The schemes provide enhanced traffic performance in homogeneous environments and also relieve hot-spot traffic. Simple channel management and easy implementation are additional features. Two types of hand-off arise in CBWL, intercell hand-offs and intracell hand-offs. A model based on multidimensional birth-death processes is devised and traffic performance characteristics showing blocking and forced termination probabilities are obtained. The results, which are validated by simulation, indicate that CBWL can provide significantly improved traffic and hand-off-performance in comparison with non-borrowing cellular schemes
