Dual-mode handsets and multimode terminals are generating demand for solutions that enable convergence and seamless handover across heterogeneous access networks. The IEEE 802.21 working group is creating a framework that defines a Media Independent Handover Function (MIHF), facilitates the handover across heterogeneous access networks and help mobile users to experience a better performance du...

Current wireless networks include various wireless technologies such as 3G (WCDMA), 4G (LTE), W LAN, WiMAX. The movement of a user within or among different ty pes of networks requires vertical handover. There are many existing algorithms for predicting and executing vertical handover considering various network parameters. However, they usually don’t consider the individual mobile user. Genera...

BACKGROUND Poor clinical handover creates discontinuities in care leading to patient harm. However, the field of handover research continues to lack standardised definitions and reliable measurement tools to identify factors that would lead to harm reduction and improved safety strategies. OBJECTIVE This paper introduces a conceptual framework to underpin a research agenda around the importan...

In hierarchical multi-tier network, preventing unnecessary handover is one of the most important matters to prevent performance degradation. To do this, some recent handover approaches propose to delay the handover from macro to small scale cell. So, in this paper, we introduces a concept of delaying inter-tier handover techniques to prevent temporary visitor being handed over to small cell.

Purpose – The paper aims to propose an optimized handover necessity estimation scheme for amobile terminal (MT) traversing from a third-generation (3G) cellular network into the wireless local area network (WLAN) cell for reducing the number of handover failures and unnecessary handovers. Design/methodology/approach – The proposed optimized handover necessity estimation scheme comprises of two ...

Next generation wireless networks are envisaged to be an integration of different wireless networks and demand the ability of users to move from one network domain to another network domain seamlessly. Also these networks require superior handover techniques to provide ubiquitous access to roaming users with maximum network resource utilization. In order to fulfill these requirements, it is ess...

OBJECTIVES This study identifies best practice for shift handover and introduces a new tool used to hand over clinical and operational issues at the end of a shift in the emergency department (ED). METHODS Literature review, semi-structured interviews and observations of handover were used to develop a standardised process for handover. Participants were ED middle grades, consultants and seni...

LTE (Long Term Evolution) is a fourth generation cellular network technology that provides improved performance related to data rate, coverage and capacity compared to legacy cellular systems. In this context, one of the main goals of LTE is to provide fast and seamless handover from one cell to another to meet a strict delay requirement while simultaneously keeping network management simple. H...

handover is not a unilateral transfer of information and that when poorly conducted it can degrade quality of care [1]. A key feature of handover required by clinicians is the big picture, which shapes the viewpoint of the receiving party [1]. Frequently this is obscured in critically ill patients by a surfeit of physiological variables or results, and this ‘noise’ denigrates the handover proce...

The integration of various cellular networks; wireless Local Area Networks, Worldwide interoperability for Microwave Access (WiMAX), Long Term Evolution (LTE), mobile ad-hoc networks and personal area networks utilizing all IP-based architecture constitutes 4G wireless networks. The mobile users roam across the boundaries of different access networks which gives rise to the requirement of effec...
