Method for supporting mobility management entity, user equipment and extended discontinuous reception mechanism

摘要

Devices and methods are generally described that enable simultaneous use of a power saving mode (PSM) and a requested extended discontinuous reception (eDRX) mode by a user equipment (UE). A mobility management entity (MME) may receive an active timer (AT) request and an eDRX cycle time (eCT) request. The MME may store a UE specific paging timer that is larger than the eCT request. Otherwise, the MME may set the AT response and eCT response to be equal to the AT request and eCT request if the AT request is greater than the predetermined number of eDRX cycles. MME may set AT response smaller than AT request and / or eCT response smaller than eCT request, or AT response smaller than AT request, use DRX cycle time, or AT response AT request The eCT response may be set smaller than the eCT request.
