Performance Evaluation of Service and Power Based Handover Algorithm in Multi Radio Access Technologies

摘要

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.
