The move towards an increasingly heterogeneous infrastructure has been one of the directions followed by most mobile operators in recent years. Here, one of the problems still waiting for a solution is how to enable multi-mode mobile terminals to freely roam between the different wireless systems used by the network operator for providing access to its users. The IEEE 802.21 is just one of the standardization...
Recently, network selection for heterogeneous wireless networks has been widely studied by categorizing and employing various factors to decide the best network. Mobility-related factors can be used to represent mobility features of mobile terminals (MTs) and mobility support capabilities of wireless networks, but they are complicated in usage and are not well used in related works. In this paper,...
The vision of next generation networks is an all-IP network supporting heterogeneous access technologies such as WLAN, UMTS and WiMax for the purpose of providing the mobile user with roaming capability across different networks. To enable this type of mobility known as vertical handover (HO), a special mobility management is proposed in order for the handover to be performed with service continuity...
