Problems solved by technology

[0009] In view of this, the main purpose of the present invention is to provide a method and system for UE power saving to solve the problem of UE battery life due to excessive monitoring of PDCCH and other unnecessary data transmission by UE when network applications and services end. The waste of power and the problem of shortening the standby time

Embodiment Construction

[0043] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0044] When the UE is in the RRC connection state, it knows that data transmission and reception has ended through upper-layer applications and services, and judges that data transmission and reception will not occur for a long period of time. This judgment can be implemented as follows:

[0045] For different network services, their data characteristics will be different, and their quality of service requirements will also be different. For example, real-time services such as audio and video will be more sensitive to delay; e-mail or file transfer protocol (FTP, File Transfer Protocol) services can tolerate delay, and the frequency of occurrence will not be very high, and there will be delays between sending and receiving emails twice. relatively large time interval. For services such as e-mail or FTP, there will ...

Abstract

The invention discloses a user equipment (UE) power saving method and a system thereof. The method comprises the following steps: UE sends a request message of entering into a power saving state to an evolved Node B (eNB) and requests to modify self configuration; the eNB receives the request message and indicates the UE to enter into the power saving state; the UE executes a corresponding operation according to indication of the eNB and enters into the power saving state. Through the method and the system of the invention, problems of waste of electric quantity of a cell of the UE and shortening of standby time caused by that the UE monitors physical downlink control channel (PDCCH) and other unnecessary data transmission excessively when a network application and a service are finished are solved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular to a method and system for saving power of user equipment (UE, User Equipment) under long-term evolution technology (LTE, Long Term Evolution). Background technique [0002] In the LTE system, monitoring the downlink channel by the UE will increase battery power consumption, and stopping monitoring the downlink channel can save battery power. In order to save the battery power of the UE and prolong the standby time, LTE adopts a mechanism called Discontinuous Reception (DRX, Discontinuous Reception). Using the DRX mechanism, the UE will receive discontinuous data and monitor the downlink channel intermittently, thereby saving a certain amount of power. [0003] The DRX mechanism of LTE is divided into DRX in an idle (IDLE) state and DRX in a radio resource control (RRC, Radio Resource Control) connected state. Among them, the IDLE state means that the UE...
