Abstract
For an ultra dense network (UDN) having small cells of highly overlapped coverages, a user equipment (UE) selects in a handover process a preferred base station (BS) from candidate BSs for minimizing occurrence of handover events. The UE computes finite differences consisting of a first-, a second-, and one or more higher-order differences, according to received signal strength (RSS) values obtained for each candidate BS. A preference level, which is a total number of finite differences having consecutive order numbers, including the first-order difference, and being positive or non-negative, is computed for each candidate BS. One or more favorable candidate BSs from the candidate BSs are identified such that the group of such favorable candidate BSs has the same preference level that is maximum among all the preference levels computed for the candidate BSs. The preferred BS is selected from the group of such favorable candidate BSs.
