In this paper, we introduce the user's privileges and traffic maximum delay tolerance as additional dimensions in the call admission control processes to efficiently control the utilization of LTE-A network resources. Based on this idea, we propose an efficient call admission control scheme named "Delay Aware and User Categorizing-based CAC with Adaptive Resource Reservation", where the user priority is adjusted dynamically based on the current network conditions and the users' categorizations and traffic delay tolerances, to increase the network's resource utilization and at the same time to maximize the operators' revenue. In this proposed scheme, the users are classified into Golden users and Silver users, and the type of service per user is classified as real-time (RT) and non-real-time (NRT) services. We compare the performance of the proposed scheme with the corresponding results of previous schemes, referred to as the adaptive resource reservation-based Call Admission Control (ARR-CAC), where user categorization and delay were not taken into consideration in the call admission control process. Simulation results indicate the superiority of the proposed scheme because it is able to achieve a better balance between system utilization, users' privileges provided by network operators and QoS provisioning compared to the ARR-CAC scheme.

Abstract:Call admission control plays a crucial role in providing quality of service to the different services in mobile broadband networks (WiMAX, LTE). A new connection is admitted only when the network can support the QoS needs of the connection without degrading the QoS for existing connections. An efficient call admission control algorithm ensures higher throughput and fewer delays for the admitted connections. In this paper a graded priority-based call admission control algorithm is proposed for LTE and WiMAX networks. The number of permissible connections shall be segregated into two classes. The new connection shall be graded, prioritized, and admitted based on the device requesting the connection. Simulation results show that graded priority-based admission control algorithm improves the connection admission rate from 3% to as high as 30% for select users. This results in higher throughput for priority users.
