Mobility Management in 4G Networks
Over the past 25 years, the evolution of the internet and the advances of wireless technologies have made a tremendous impact on lifestyle of people around the world. Together, these two factors have changed the way people communicate, work, and get their entertainment. In order to be always best connected for various applications, the network selection procedure in heterogeneous multi-access e...
متن کاملMobility Management Approaches for 4G Networks
The fourth generation (4G) of mobile communication networks will provide a multitude of real-time and non-real-time services on top of an IP-based platform. Subscribers can access these services over arbitrary radio-access technologies, including existing WPAN, WLAN, WMAN, and WWAN technologies as well as future air interfaces for broadband wireless access. Thereby, 4G networks pose high demand...
متن کاملIssues in Mobility Management in 4G Networks
Researchers and vendors are expressing a growing interest in 4G wireless networks that support global roaming across multiple wireless and mobile networks—for example, from a cellular network to a satellite-based network to a high-bandwidth wireless LAN. The 4G mobile system is an all IP-based network and provides the user access to different radio access technologies. In this environment, roam...
متن کاملSIP-based Mobility Management in 4G networks
4G systems will need to integrate several IP-based access technologies in a seamless way. In this paper, we first describe the requirements of a Mobility Management scheme for multimedia real-time communication services; then, we report a survey of the Mobility Management schemes proposed in the recent literature to perform vertical handovers between heterogeneous networks. Based on this analys...
متن کاملFast End-to-End Mobility Support Using SIP for Vertical Handoffs in 4G Wireless Communication Networks
The mobility management is a significant issue in 4G heterogeneous networks. However, the mobility needs to be managed by upper layer in the networks because of the limitation of mobility management at link layer. Session Initiation Protocol (SIP) supports personal mobility so that a user can be found independent of location and network device. But it cannot support IP mobility and cannot maint...
