Embodiment approach

[0130] The first implementation mode, specifically, if the core network element supports extended DRX, the core network element notifies the base station through signaling or OA&M or statically configures it in the base station to instruct the base station to broadcast and notify the terminal. On the premise that the network element supports extended DRX at the same time, the base station broadcasts the ability to support extended DRX. After receiving the broadcast instruction from the base station, the terminal sends a NAS request message to the core network element. The request message can be an attach request or an RAU request message. or a TAU request message, and carry the extended DRX value in the NAS request message, the core network element records the extended DRX value and carries it in the paging message and sends it to the base station, and the base station receives the extended DRX value carried in the paging message After the value is set, the extended DRX value i...

Abstract

Embodiments of the present invention provide a discontinuous reception (DRX) communication synchronization method and device. The method includes receiving a paging message issued by a network element of the core network, the paging message including an extended discontinuous reception DRX indication and / or an extended DRX; calculating a paging time according to the extended DRX indication and / or the extended DRX; Paging is performed to the terminal at the paging time. The embodiment of the present invention solves the problem of extra power consumption caused by frequent monitoring of paging messages during the communication process between the terminal and the network, and also avoids paging loss caused by DRX asynchrony between the terminal and the network.

Description

technical field [0001] The invention relates to communication technology, in particular to a communication synchronization method and device for discontinuous reception. Background technique [0002] With the continuous development of the mobile communication industry, the signaling interaction among the user equipment (User Equipment, hereinafter referred to as UE), base station and core network (Core Network, hereinafter referred to as CN) is more and more frequent, and the UE needs to monitor the paging in real time. Channel information ensures that when the CN sends a paging message to the UE, the UE can monitor the paging message synchronously, but this real-time monitoring of the UE increases the power consumption of the UE. [0003] In order to save the power consumption of the UE, Discontinuous Reception (DRX) technology is introduced in the prior art, that is, the UE stops listening to the channel for a period of time, is in a sleep state, and wakes up every once in...
