Extending Always Best Connected Paradigm for Voice Communications in Next Generation Wireless Network

Abstract

Selecting transparently a proper network connection for voice communication will be a fundamental requirement in future multi-mode heterogeneous wireless network. This paper extends Always Best Connected (ABC) to a fine-grain paradigm called Always Best Network Connection (ABNC) to address this issue. Instead of selecting a best access network as in conventional ABC, ABNC enable users to select a best network connection, which consists of source and destination access network pair, to satisfy quality constraint and users' preference. To support ABNC, we develop a user profile to specify network connection priority. Meanwhile we extend SIP and propose a network selection information service (NSIS) based on MIH (Media Independent Handover) to collect information of both source and destination access networks for decision making. Finally, AnalyticHierarchy Process (AHP) is used to recommend a network connection with assistance of user profile and NSIS. An example is illustrated to show that AHP can successfully select a good network connection that fulfill the requirement of users.

Multihomed Mobile Network Architecture

“…Calculating the criteria weights based on the rating data was implemented using the pairwise comparison method. This method has been adopted related works such as [15] and [16]. The criteria are compared against each other to build a comparison matrix.…”

Advances in Vehicular Networking Technologies

“…In other works the message propagation model is based on the main VANET characteristics such as number of hops, vehicle position, mobility, etc. In (Yousefi et al, 2007) the authors consider a single-hop dissemination protocol based on Quality-of-Service metrics, while in (Chen et al, 2008) a robust message dissemination technique is illustrated, based on the vehicles position. Finally, the authors in (Nadeem et al, 2006) present a data dissemination model based on bidirectional mobility of paths between a couple for vehicles.…”

Coupling Activity and Performance Management with Mobility in Vehicular Networks

“…This process will make use and extend the IEEE 802.21 signaling. Other proposals (Chung et al, 2008), (Jesus et al, 2007) deal with the mechanisms involving mobility decisions and mobility signaling more deeply. To better understand this process, the core network should be seen as a mediator of information.…”
