Abstract

Mobility load balancing (MLB) is an effective method employed by 3GPP to transfer traffic from a hot-spot cell to neighbouring cells. This paper designs a cooperative mobility load balancing (CMLB) scheme in relay cellular networks. After partner cell selection, in the traffic shifting stage, the partner cell analyses hot-spot cell´s traffic shifting request and the idle spectrum of relay station (RS), in order to address the RS aggravating load problem and improve the handover performance. Simulation results show that the proposed CMLB scheme can mitigate the RS aggravating load problem and also reduce the handover failure rate.
