Call admission protocols play a central role in determining both the performance of any network, and the revenue of the network. The call admission protocol must decide either to accept the call or reject it, Thus having an impact on both the quality of calls and the network revenues. The call admission protocol must deal with multiple classes of calls having different requirements, requesting ...

Call admission control algorithms that reduce dropped calls in CDMA cellular systems are discussed in this paper. The capacity of a CDMA system is confined by interference of users from both inside and outside of the target cell. Earlier algorithms for call admission control is based on the effective traffic load for the target cell if one call is accepted. These algorithms ignore the interfere...

This paper evaluates call admission control algorithms for a cellular or microcellular system. Algorithms are evaluated based on two Quality of Service (QoS) metrics: the new call blocking probability, which is the probability that a new call is denied access to the system, and the forced-termination probability, which is the probability that a call that has been admitted will be terminated pri...

Wireless/mobile communication systems are becoming increasingly popular in recent years. As the wireless resources are scarce, it is important to allocate resources efficiently and carefully, in order to achieve maximum output. The call admission control schemes play a significant role in providing the desired quality of service (QoS) by judiciously assigning the radio channels that are availab...

This paper introduces a novel Q-value based adaptive call admission control scheme (Q-CAC) for distributed reinforcement learning (RL) based dynamic spectrum access (DSA) in mobile cellular networks, which provides a good quality of service (QoS) without the need for spectrum sensing. A DSA algorithm has been developed in this paper using the stateless Q-learning algorithm with Win-or-Learn-Fas...

This paper proposes a new call admission control scheme considering the call dropping probability of ongoing calls in LEO satellite networks. Quality of service (QoS) provisioning of low handover failure probability is used in the proposed call admission control (CAC) scheme to guarantee predefined acceptable call dropping probability for each call. To ensure the call dropping probability the h...
