Problems solved by technology

However, during the activation period of the VoIP service, it is not necessary to send the PDCCH every 20ms. In most cases, only the PDSCH is sent. Therefore, the 20ms long DRX Cycle makes the terminal have to perform several PDCCH blind detections every 20ms. The method still exists unnecessary waste

Embodiment Construction

[0051] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0052] In the LTE (Long Term Evolution, Long Term Evolution) system, the uplink and downlink service data transmission of the UE uses a shared channel. Both uplink and downlink scheduling are controlled by the base station. The terminal needs to monitor and blindly monitor the PDCCH channel. Detect and judge whether there is a scheduling signaling for itself. If the UE is in the RRC_CONNECTED state but has only established a VoIP service bearer, since VoIP is a service with a regular service source data packet size and regular sending in...

Abstract

An embodiment of the invention provides a power saving method based on a discontinuous receiving function. The power saving method based on the discontinuous receiving function comprises: a terminal receives configuration information for discontinuous DRX parameter receiving of network voice call VoIP service sent by a base station; when the terminal is in a DRX activation state, the terminal performs one-time PDCCH blind detection in a long DRX Cycle when the VoIP service is in an activation period; the terminal perform one-time or two-time blind detection in a short DRX Cycle when the VoIP service is in a silence period; the terminal is in a DRX non-activation state and performs one-time or two-time blind detection in the short DRX Cycle when receiving MAC DRX CE sent by the base station. In the scheme, by setting the long DRX Cycle in the configuration information of VoIP service DRX parameters sent by the base station, the PDCCH blind detection times are decreased, and the power saving purpose is achieved.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular, the present invention relates to a power saving method and equipment based on a discontinuous reception function. Background technique [0002] The 36.321 protocol achieves the purpose of discontinuous monitoring of PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) by UE (User Equipment, User Equipment) through a series of processing procedures of standardized DRX (Discontinuous Reception, discontinuous reception). For details, refer to The relevant content of Section 5.7 DRX of the 36.321 agreement. [0003] figure 1 It is a schematic diagram of the relationship between timers in the prior art, showing the relationship between various timers. [0004] According to the agreement, DRX is divided into two states: DRX active state and DRX inactive state. In the DRX activation state, the UE in the RRC_CONNECTED state does not monitor C-RNTI (Cel...
