Optimal Call Admission to a Mobile Cellular Network

چکیده
To ful ll 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 e ectiveness of a call admission policy for maximizing the call completion rate and for reducing the hando dropping is studied. Channel reservation policies for hando s are also examined for di erent system parameters. In addition, several symmetry properties of the optimal policies which e ectively truncate the size of policy space, are mathematically established.

It is well known that in stochastic service systems such as telecommunications networks, selective denial of service based on system state can enhance performance. For example, in a cellular mobile network, preference might be given to hando calls over new calls when the system is more heavily loaded. When the service center can be modeled as a markov process, there exist means to calculate the...
