This thesis deals with optimal frequency assignment for cellular mobile radio communication systems where handoff and fixed channel assignment are assumed. In addition, the systems considered here are assumed to adopt the priority scheme which exclusively reserve some of channels, called guard channels, in each cell for handoff calls.
A heuristic algorithm for the optimal guard channel assignment in each cell is developed so as to minimize the handoff calls blocked without significantly increasing the originating calls blocked. Marking use of the characteristics of handoff, we also propose a new traffic model of handoff calls where the assumption on mean arrival rate is relaxed. Finally, our heuristic algorithm is applied to the newly proposed traffic model.
