Abstract

Abstract:

In the Long Term Evolution (LTE) system, to ensure the normal execution of communication, each cell must maintain a neighbor cell list which decides the scope and direction of a terminal’s switch. The traditional approach for configuring a neighbor cell list is carried out by a network engineer according to the site survey results, which not only consumes large amounts of time and manpower, but also can not present the statistical characteristic of the whole network. An automatic neighbor cell list generation algorithm based on the adaptive SINR threshold is proposed. The SINR threshold and “vote model” are introduced in this algorithm, which takes into full account the cell type in the LTE network, and effectively reflects the actual network environment. The algorithm ultimately realizes dynamic management of the neighbor cell list. Simulation results show that different SINR thresholds can affect the redundancy ratio and accuracy ratio of a neighbor cell list.

Key words: LTE, neighbor cell list, SINR threshold, vote model
