Abstract

To fulfill the future demand for and increase the reliability of mobile cellular service, we have explored the use of a call admission policy that constitutes a dynamic channel allocation scheme for a cellular system. The call admission policy optimizes a weighted blocking criteria for a queueing network model of a mobile cellular system. In this context, the call admission problem is formulated as a Markov decision process. The value iteration method has been applied to a uniformized chain of a cellular highway system. The effectiveness of a call admission policy for maximizing the call completion rate and for reducing the handoff dropping is studied. Channel reservation policies for handoffs are also examined for different system parameters. In addition, several symmetry properties of the optimal policies which effectively truncate the size of policy space, are mathematically established.
