Future 3G and 4G mobile networks will consist of wireless access technologies such as WCDMA, EDGE and 802.11a/b WLAN coexisting in a heterogeneous access network environment. Each network access technology provides different levels of coverage and QoS as well as cost to the end user. This paper published by Cork Institute of Technology examines the use of policy based management techniques for admission management by service providers offering multiple wireless network types and for selection between network types and providers by users. Adaptive policy based admission control schemes for seamless mobility between heterogeneous networks is proposed.
Future mobile networks will not consist simply of one radio access technology such as WCDMA (wideband code division multiple access) or EDGE (Enhanced Data Rate For GSM Evolution), but will contain many different technologies. This paper published by Cork Institute of Technology presents a state of the art survey in resource management in heterogeneous networks. In this paper emphasis is given to admission control and mobility management between different access schemes both of which are critical in a heterogeneous network environment as they balance the load across networks while maintaining sufficient QoS for varying traffic types.
