Call Admission Control in HAP W-CDMA Cellular Systems
Among various radio sources which control different dependencies/functions, in this article, we will talk about the Call Admission Control (CAC), and we are supposed to confine our concentration on W-CDMA which is based on high raised platforms, since during the recent years remarkable amount of attention has been focused on platforms located in stratosphere layer [1]. Firstly, we study the cap...
متن کاملCall admission control in multiservice high altitude platform (HAP) W-CDMA cellular systems
Of the various radio resource management functions, in this paper we focus on call admission control (CAC). We propose a CAC scheme for multiservice High Altitude Platform (HAP) wideband code division multiple access (W-CDMA) cellular systems that caters for multimedia services. HAPs have known increasing popularity during the past few years and are expected to play a pivotal role in the teleco...
متن کاملAdaptive Call Admission Control in Tdd-cdma Cellular Wireless Networks
The Code Division Multiple Access system with Time Division Duplex mode (TDD-CDMA), adopting unbalanced slot allocation between uplink and downlink, can meet the asymmetric traffic requirement of multimedia services. Here a call admission control policy is proposed to support different multimedia applications. The scheme operates at the connection-level where the CDMA code of ongoing call can b...
متن کاملGlobal versus Local Call Admission Control in CDMA Cellular Networks
We design and implement global and local CAC algorithms for CDMA networks, and compare their network throughput for various mobility scenarios. The global CAC algorithm is inherently optimized and uses global information in making every call admission decision; it yields the best possible performance but has an intensive computational complexity. The design of the local CAC algorithm uses globa...
متن کاملCall Admission based on Interference in DS-CDMA Cellular Systems
The increase in the size of the wireless community together with new applications obliges better utilization of the scarce wireless resources. The requirement for communications on-the-move compels the call admissions mechanism to combat forced call termination. Channels need to be reserved in the surrounding cells, and call admissions must employ mechanisms considering these reservations. Keep...
