Flexible call admission control with preemption in LTE networks [PDF]
2016 IEEE International Conference on Communications (ICC), 2016 This paper introduces a new call admission control (CAC) mechanism for Long Term Evolution (LTE) networks supporting multimedia services with different classes of traffic. Our CAC mechanism classifies calls into real time and non-real time users, then estimates the channel quality based upon the received signal strength (RSS) value, and finally ...

Joint call admission control and resource allocation for H.264 SVC transmission over OFDMA networks [PDF]
, 2010 This paper aims to combine adaptive subcarrier allocation and bit loading with the transmission of the H.264 SVC (Scalable Video Coding) encoded video sequences in order to increase the number of supported users in the system and provide the best quality

Structural properties of optimal coordinate-convex policies for CAC with nonlinearly-constrained feasibility regions [PDF]
, 2011 Necessary optimality conditions for Call Admission Control (CAC) problems with nonlinearly-constrained feasibility regions and two classes of users are derived. The policies are restricted to the class of coordinate-convex policies.

Call admission control for wireless personal communications [PDF]
Computer Communications, 2003 Call admission control (CAC) in future wireless personal communication systems is to simultaneously achieve quality-of-service satisfaction and high resource utilization. It poses significant technical challenges due to scarce radio spectrum, user mobility, hostile wireless propagation environment, end-to-end connectivity, and dynamic nature of ...

Index policies for the admission control and routing of impatient customers to heterogeneous service stations [PDF]
, 2009 We propose a general Markovian model for the optimal control of admissions and subsequent routing of customers for service provided by a collection of heterogeneous stations. Queue-length information is available to inform all decisions.

Call Admission Control Jointly with Resource Reservation in Cellular Wireless Networks
EURASIP Journal on Wireless Communications and Networking, 2010 To efficiently utilize the total resources and to serve mobile users demanding for different types of service, system resource utilization of these services should be considered, and efficient resource management techniques should be developed.

Call admission control with opportunistic scheduling scheme [PDF]
Wireless Communications and Mobile Computing, 2009 AbstractIn this paper, a rate‐based admission control scheme for a single shared wireless base station with opportunistic scheduling and adaptive modulation and coding (AMC) is proposed. The proposed admission scheme maintains minimum average rates of the admitted users, i.e., new users will be admitted if the base station has enough resources to ...
