“…To overcome these shortcomings, a number of schemes were proposed for multiple integrated networks by controlling the shared resources in an efficient and adaptive way. In [4,5], a new CAC admission control with dynamic resource allocation for two types of services in a 3G wireless network was proposed and analyzed. This CAC combines the advantages of CS and CP between real-time and non-real time services in an efficient and adaptive way using dynamic priority.…”

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.

“…In the CS scheme, calls of every class of services share the bandwidth pool [3]. Whereas, in the CP scheme, the bandwidth for each class of services is exclusively reserved [4]. In the threshold scheme, a newly arriving call is blocked if the number of calls of corresponding service is greater than or equal to a predefined threshold.…”

Abstract-This paper introduces a call admission control (CAC) strategy for LTE femtocell networks supporting multimedia services with different classes of traffic and diverse bandwidth requirements. In this work, the multiservice CAC strategy composes of two parts: subscriber authentication and queuing admission control. Theoretical analysis and simulation are performed on three key principles. Comparing with the typical strategy, simulation results indicate that better probabilistic connection-level QoS parameters are achieved by using the proposed strategy.

Different quality-of-service (QoS) required types of multimedia services and need a guaranteed service rate in wireless multimedia networks. When the number of user arrivals increases, bandwidth degradations may occur due to limited bandwidth nature of cellular wireless networks. The bandwidth that should be assigned to user cannot be met for QoS provisioning in congested network. In this paper, a priority-based call admission control scheme with bandwidth adaptation is proposed to provide the required QoS to service users and to utilize the bandwidth effectively. An analytical model is developed to evaluate the numerical results. Proposed scheme differentiates the services according to their call-level QoS priorities as non-prioritized and prioritized calls and provides the satisfactory QoS under the upper bound limitations. Further, bandwidth adaptation policy maintains the higher performance results in terms of blocking and dropping probabilities, resource utilization and throughput of non-prioritized calls.
