3GPP Technologies: Load Balancing Algorithm and InterNetworking

Abstract

Multiple Radio Access technology (RATs) is the way forward by the cellular operators. Such coexistence between the different technologies can introduce many operational coordination and management problems. Long Term Evolution (LTE) advanced and otherwise has been deployed in the same cell site as of Universal mobile Telecommunication (UMTS) cells. LTE and UMTS networks have different Radio Resources Management (RRM) functionality and network architecture. Therefore; most operators have considered common radio resources management functionality in more than one way in order to use radio resources efficiently. Such deployment has to be concerned with many technical issues; among others, the internet traffic and load balancing among multi RAT. After all; the network will be connected to the World Wide Web in one form or another. In this contribution, we are devising a new algorithm that considers cell selection based on internet traffic modeling approaches. At the same time we address the issue of load balancing among the different RATs.
