Abstract:

In this paper, a new scheme about mobility load balance considering system overhead is proposed. The scheme adjusts the handover parameters, the cell-specific offset between neighboring cells (CSON), adaptively based on the load ratio between neighboring cells. The first order derivation of the CSON on the load difference is defined as the urgency function of the CSON adjustment and the characteristics of the urgency function are analyzed. Besides, a quadratic function is adopted to give an example to the CSON adjustment and the condition of the handover oscillation avoidance is derived. Furthermore, we develop a long-term-evolution(LTE) simulation platform to evaluate the proposed algorithm. Numerical results show that the scheme brings an important gain on call admission rate and the handover failure rate with less handover times.
