Abstract: In a cellular communication system (40) a handoff candidate list is generated for a source sector (51) by eliminating (12) from a list of potential handoff candidates (52-56) any sectors having an interference parameter exceeding a threshold value. The list is further reduced by determining (21) a handoff radius (60) and eliminating any candidate sectors (52-56) that fall outside the hadoff radius (60). Candidate sectors (52-56) that do not have overlapping coverage areas are also eliminated (23). In addition, candidate sectors (52-56) having a relative angle of sight to the source sector (51) that exceeds a maximum angle are also eliminated (24). Finally, the list is reduced (15) to a preset number of candidates dependent upon the interference parameter.

Abstract translation: 在蜂窝通信系统（40）中，通过从具有超过阈值的干扰参数的任何扇区的潜在切换候选（52-56）的列表中消除（12），为源扇区（51）生成切换候选列表。 通过确定（21）切换半径（60）并消除落在超负荷半径（60）之外的任何候选扇区（52-56）来进一步减少列表。 也没有覆盖区域重叠的候选部门（52-56）（23）。 此外，也消除了具有超过最大角度的源扇区（51）的相对视角的候选扇区（52-56）（24）。 最后，根据干扰参数将列表减少到预定数量的候选者（15）。
