摘要： A method for shedding traffic load in a code division multiple access mobile communication system, the method performing a soft handoff operation using the ratio of the received forward link pilot signal power to the sum of all interference signals power to transfer a portion of traffic load in the present serving cell with a high traffic density to an adjacent cell with a low traffic density. When the amount of traffic load in the present serving cell is increased and thus exceeds a link capacity of the present serving cell, handoff parameters of all mobile stations in the present serving cell can be updated on the basis of a power allocation state managed by a base station without reducing the coverage of a forward link. On the basis of the updated handoff parameters, the soft handoff operation is performed from a part of the mobile stations in the present serving cell with the high traffic density (for example, mobile stations at the edge of the present serving cell) to the adjacent cell with the low traffic density. Therefore, the excessive traffic load amount in the present serving cell can effectively be shed.
摘要翻译：一种用于在码分多址移动通信系统中消除业务负载的方法，所述方法使用所接收的前向链路导频信号功率与所有干扰信号之和的比率来执行软切换操作，以将部分业务负载传输到具有低业务密度的相邻小区的具有高业务密度的当前服务小区。当当前服务小区中的业务负载量增加并且因此超过当前服务小区的链路容量时，可以基于由服务小区管理的功率分配状态来更新当前服务小区中的所有移动站的切换参数基站，而不减少前向链路的覆盖。基于更新的切换参数，从具有高业务密度的当前服务小区中的一部分移动站（例如，当前服务小区边缘的移动站）到相邻的处理单元执行软越区切换操作交通密度低的小区。因此，可以有效地减轻当前服务小区中的过量业务负载量。
