MOBILITY MANAGEMENT ENTITY, USER EQUIPMENT AND METHOD TO SUPPORT EXTENDED DISCONTINUOUS RECEPTION MECHANISM

摘要

Devices and methods of enabling simultaneous use of power saving mode (PSM) and a request extended Discontinuous Reception (eDRX) mode by user equipment (UE) are generally described. A mobility management entity (MME) may receive a request active timer (AT) and a request eDRX cycle time (eCT). The MME may store a UE-specific paging timer larger than the request eCT. Otherwise the MME may set a response AT and response eCT equal to the request AT and request eCT when the request AT is greater than a predetermined number of eDRX cycles. The MME may set the response AT less than the request AT and/or the response eCT less than the request eCT, or: the response AT less than the request AT and use a DRX cycle time or the response AT to be the request AT and the response eCT less than the request eCT.
