  • In the presence of heterogeneous traffic flows generated by services with different QoS requirements in Low-Earth-Orbit (LEO) satellite networks, a framework of Call Admission Control (CAC) and handover management scheme is proposed based on Optimal Multi-Threshold Channel Reservation (OMTCR) policy as well as its corresponding theoretic analysis approaches to evaluate the connection-level QoS metrics. To determine the optimal threshold parameters vector of OMTCR under given system parameters and input traffic conditions, the revenue concept in economics is referenced to formulate unconstrained and QoS-constrained system revenue objective optimization models. Results are presented to demonstrate the better performance of the proposed OMTCR than conventional Completely Sharing (CS) and Guard Channel (GC) policies under heterogeneous traffic conditions with different user QoS requirements and system revenue objectives.
