Loss models can be used to determine engineered capacity of circuit-switched telecommunications systems. They readily model the multi-service, multi-resource nature of call admission control (CAC) schemes for such systems, including service prioritization via the use of resource reservation. Third generation wireless networks (3G) are incredibly complex with regard to system resources and supported...
In this paper, C3G-A (Combining the third generation mobile communication network and Ad hoc network) system is presented. Call Admission Control (CAC) plays an important role in radio resource management of wireless communication networks. It permits or denies the call arrival connection requests based on the certain criteria. To analyze the performance of CAC in C3G-A system, Markov chain model...
The next generation wireless networks (NGWN) should cater the varied requirements of the user and applications. The call admission control (CAC) is one of the radio resource management (RRM) technique used in the wireless networks. Unlike the CAC in homogeneous wireless networks the CAC in next generation wireless networks is very complex. In the next generation heterogeneous wireless networks, a...
Capacity of CDMA system depends on an interference level in the system. There are therefore RRM (radio resources management) functions, which are responsible for supplying optimum coverage, ensuring efficient use of physical resources and providing the maximum planned capacity. A call admission control algorithm based on load factor evaluation and a fuzzy logic based call admission control algorithm...
The multiple choices of access networks offer different opportunities and overcome the limitations of other technologies. Optimal selection of interface is a big challenge for multiple interfaces supported mobile terminals to make a seamless handover and to optimize the power consumption. Seamless handover, resource management, and CAC to support QoS and multiple interface management to reduce power...
Mobile telecommunication new services are based on data networks specially Internet. These services include http, telnet, ftp, SMTP, etc. In addition we recognize that a mobile network is a multi-user network. Layer 3 of UMTS system provides call admission control and radio resource management. QoS can be guaranteed based on these modules. In order to have a suitable distribution of resources in a...
