Abstract:
The resource management for telecommunications network is a very old
problem, and all current telecommunication switches have a number of
the resource management algorithms implemented within the system.
Historically, the telecommunication industry was a monopoly business
so all these algorithms normally optimized the capacity of the
system under a certain QoS constraint. In all cases, there is
assumption that the customer does not have any choice to leave the
network; his only concern is the QoS. The competitive wireless
network brings different perspective as customers can leave the
network, in case he is not satisfied with the provider and join
another provider. With number portability in place, this has become
more easy for the user. In this work, we attempt to use the
Non-cooperative Game Theory based algorithm, to manage the resources
in a CDMA network. The resource management is implemented in two
steps, macro-level Admission Control and micro-level flow control.
The uniqueness of this work is its application of customer
Churn-rate in the resource management. Customer Churn-rate includes
the uncertainty created by the competition as well as the
differences of the customer's reaction to provider's resource
management methods. Our simulation results show that the provider
can improve their net revenue by using this algorithm compared to
the traditional resource management techniques.
