Abstract:
1. A method, comprising, in a user equipment (UE): determining two or more discontinuous reception (DRX) cycle lengths, including determining a first DRX cycle length being broadcast by a long term evolution based (LTE-based) evolved node B (eNB) in a cell and determining a second DRX cycle length proposed by the UE operating in the cell; and determining to skip a tracking area update (TAU) procedure to configure a DRX cycle in a LTE-based mobility management entity (MME) if the first DRX cycle length being broadcast by the eNB is a lowest DRX cycle length among the two or more determined DRX cycle lengths, and to initiate the TAU procedure if the first DRX cycle length being broadcast by the eNB is greater than a lowest DRX cycle length among the two or more determined DRX cycle lengths.
