First Claim
1. A method of operating user equipment (UE) in a cellular telecommunications system, the method comprising:
- causing the UE to begin operating in a power saving state by determining that a first set of predefined criteria have been satisfied; and
causing the UE to leave the power saving state by determining that a second set of predefined criteria have been satisfied,wherein determining that the first set of predefined criteria have been satisfied includes;
making a plurality of signal quality measurements of a signal received from a serving cell in the telecommunications system;
making a plurality of signal quality measurements of a signal received from one or more neighboring cells in the telecommunications system;
determining a first trend line from the signal quality measurements of the serving cell in the telecommunications system;
determining a second trend line from the signal quality measurements of the one or more neighboring cells in the telecommunications system; and
determining that the first set of predefined criteria have been satisfied if the first and second trend lines are not converging.

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.
