“…In [8], the authors presented a general architecture for the integration at the UMTS radio access level, also known as very tight coupling with emphasis on vertical handover to provide seamless session continuity. Many vertical handover algorithms are presented between UMTS, WLAN, IEEE 802.16e and DVB-H in different combination.…”

Deployment of new radio technologies in the mobile world has been gaining momentum to satisfy the customers and applications appetite for improved spectral efficiency and higher data rates. LTE (Long Term Evolution) and LTE Advanced with an enhanced air interface and optimized packet data architecture (an all IP network) that envisioned to provide enhanced data rates, reduced latency and cost efficient operations has been standardized by 3GPP. The deployment of LTE with the existing legacy cellular system such as UMTS in the same cell sites has proven to enhance the network resources available to the operators. Such deployment brings to the forefront many challenges such as mobility. Mobility is one of the cellular networks and 3GPP standard requirements to provide anywhere anytime services. The diversity of the services and the availability at the moment of several radio access networks such as legacy 3G and LTE coupled with user mobility makes the management of the handover process rather complex. In this paper, we propose a multi service handover algorithm to optimize the available network resources and power in multi radio environment (3G and LTE) based on service requests and user profile.

“…MIH provides stations with the abstract services that enable the information exchange between higher and lower layers by utilizing a media independent framework and associated services [32]. MIH standard has three key services that support the handover operation: (1) Media Independent Event Services (MIES) states events, such as Link_Up and Link_Down that signify the variations in the link quality, (2) Media Independent Command Service (MICS) provides commands to control the link state, (3) Media Independent Information Service (MIIS) provides mobile devices with energy-aware and rapid channel scanning results [12].…”

“…Then, when a VHO is needed, the main operation is merely to awake up that interface, which makes the handoff overhead even lower than in traditional handoff cases. Although being not preferable at early stage due to the technology‐specific modifications that require standardization and usual restriction on the single operator, tightly coupled approaches have been believed to be the trend for future network interworking, leading the direction of standardizations as well as investigations .…”

Proactive load balancing with admission control for heterogeneous overlay networks

The next generation wireless networks will be the coexistence of heterogeneous wireless technologies. Balancing the traffic load among different networks can effectively utilize the overall radio resources in the system. In this paper, we propose an efficient load balancing scheme for the heterogeneous overlay systems, which is applied in the call admission control process. If the available network(s) cannot provide enough resource for the request call without degrading the quality‐of‐service (QoS) obtained by the ongoing calls, the system will perform load balancing operations first by initiating vertical handoffs among networks in order to create more rooms for the request call. The load balancing algorithm is to minimize the variance between the network utilizations of the entire system, which can be formulated as a quadratic binary programming problem. Simulation results show that the proposed scheme can admit more calls into the system compared with the other three reference schemes and then improve the overall throughput. Meanwhile, the scheme can keep the networks working in effective states and provide a better QoS support for users. Copyright © 2011 John Wiley & Sons, Ltd.
