Abstract: User equipment (UE) in a cellular telecommunications system is operated such that the UE is caused to begin operating in a power saving state by determining that a first set of predefined criteria have been satisfied and is caused to leave the power saving state by determining that a second set of predefined criteria have been satisfied. Determining that the second set of predefined criteria have been satisfied includes making a plurality o f signal qualit y measurements of a signal received from a serving cell during power saving state; determining which of the plurality of signal quality measurements represents a best one of the signal qualit y measurements; determining a threshold value as a function of the best one of the signal quality measurements; and determining that the second set of predefined criteria have been satisfied if a current signal quality measurement satisfies a predefined relationship with respect to the threshold value.

Abstract: User equipment (UE) in a cellular telecommunications system is operated such that the UE begins operating in a power saving state when a first set of predefined criteria have been satisfied, and leaves the power saving state when a second set of predefined criteria have been satisfied. Determining satisfaction of the first set of predefined criteria includes making a plurality of signal quality measurements of a signal received from a serving cell in the telecommunications system, and making a plurality of signal quality measurements of a signal received from one or more neighboring cells. A first trend line is determined from the signal quality measurements of the serving cell, and a second trend line is determined from the signal quality measurements of the one or more neighboring cells. The first set of predefined criteria are considered to have been satisfied if the first and second trend lines are not converging.

Abstract translation: 操作蜂窝电信系统中的用户设备（UE），使得当已经满足第一组预定义标准时，UE开始在省电状态下操作，并且当已经满足第二组预定标准时离开省电状态 。 确定第一组预定义标准的满意度包括对从电信系统中的服务小区接收的信号进行多个信号质量测量，以及对从一个或多个相邻小区接收的信号进行多个信号质量测量。 从服务小区的信号质量测量确定第一趋势线，并且从一个或多个相邻小区的信号质量测量确定第二趋势线。 如果第一和第二趋势线未收敛，则认为第一组预定义标准已被满足。
