Abstract
Prepaid phone service requires a user to make payment
before calling. In 2.5G or the 3G networks, a user may be
engaged in multiple voice and/or data prepaid sessions at the same
time. For such services, it is important to distribute appropriate
amounts of prepaid credit units to simultaneously executed sessions
of a user. By considering the universal mobile telecommunication
system (UMTS) as an example, this paper studies the prepaid credit
allocation for the prepaid sessions. To simulataneously accommodate
more prepaid sessions for a user, we propose a credit reclaim
mechanism called prepaid credit reclaim (PCR). Analysis and simulation
experiments are conducted to investigate the performance
of our mechanism. Our study indicates that PCR can significantly
improve the performance of the prepaid mechanism.
