System and method to reduce power consumption associated with cell reselection operations
Abstract:
Embodiments are provided for resolving, at a user equipment (UE), unnecessary frequent consecutive back and forth reselections between the same two or more network cells. In an embodiment method, upon detecting predefined criteria indicating reaching a threshold frequency of reselections between the same cells, the UE switches to a defined mobility state reducing the frequency of reselections between the same cells. In accordance with the defined mobility state, the method increases a waiting time for cell reselection. The predefined criteria includes detecting the UE in a defined Static-idle state, detecting a serving cell of the UE and a strongest neighbor cell having approximately equal signal quality for a defined duration or a defined number of consecutive measurements, and detecting a number of consecutive reselections between the same cells exceeding a defined minimum threshold.
