An admission control strategy of mobile satellite system based on utility and resource borrowing

This paper proposes a Utility-Based and Channel-resource Borrowing (UBCB) call admission control strategy of mobile satellite system. In order to improve resource utilization probability and integrated performance of satellite system, the borrowing weight as the criterion of resource borrowing is introduced to improve call blocking and traffic dropping probability, and the threshold is adjusted for traffic admission-net utility to improve the congestion of the satellite system. Simulation results show that this strategy improves prominently in service grade and service value of satellite system compared to common Channel-Borrow Scheme (CBS).
