摘要： When a femto cell base station detects an intense uplink interference, the femto cell base station autonomously extends the femto cell so as to raise a probability that a mobile terminal around the original femto cell may be connected to the femto cell base station. If the mobile terminal connects to the femto cell base station, the uplink interference is reduced and total throughput is improved. Additionally, if a resultant effect of interference reduction is low, the femto cell base station returns the mobile terminal, which is connected to the femto cell base station due to the extension of the femto cell, to the original connection destination. If an evaluative criterion meets a predetermined condition, the femto cell base station restores the extended femto cell to the original size. These actions prevent degradation of performance caused by concentration of the connections of mobile terminals to the femto cell base station.

摘要翻译： 当毫微微小区基站检测到强烈的上行链路干扰时，毫微微小区基站自主地扩展毫微微小区，以提高原始毫微微小区周围的移动终端可以连接到毫微微小区基站的概率。 如果移动终端连接到毫微微小区基站，则降低上行链路干扰，提高总吞吐量。 此外，如果干扰减少的结果效果低，则毫微微小区基站将由于毫微微小区的扩展而连接到毫微微小区基站的移动终端返回到原始连接目的地。 如果评估标准满足预定条件，则毫微微小区基站将扩展毫微微小区恢复到原始大小。 这些动作防止移动终端与毫微微小区基站的连接集中引起的性能下降。
