Abstract: Methods and apparatus for identifying a subscriber station which is in motion, determining a mobility metric indicative of a level of mobility of the subscriber station and varying or updating one or more operating parameters based on the mobility metric. An apparatus can determine a measure of mobility based on one or a combination of a plurality of factors, such as variations in signal strength, variations in a channel estimate, or variations in phase or frequency of a particular signal or signal component. The one or more measures of mobility can be combined to form a single measure of mobility, the measure of mobility can be quantized to a predetermined number of mobility levels and one or more operating parameters can be varied or adjusted based on the mobility level.

Abstract: In a wireless communication system, a mobility factor is used to influence handoff. If a subscriber station has been in a low mobility state for some period of time, the system may handoff operation from a first service type to a second service type. If the mobility factor indicates that the subscriber station is moving, the system may handoff operation from the second service type back to the first service type.

Abstract translation: 在无线通信系统中，使用移动性因子来影响切换。 如果订户站已经处于低移动性状态一段时间，则系统可以将操作从第一服务类型切换到第二服务类型。 如果移动性因素指示用户站正在移动，则系统可以将操作从第二服务类型切换回第一服务类型。
