Embodiment 1
[0054] Such as figure 2 , image 3 As shown, a method for adjusting DRX parameters in LTE according to the present invention includes:
[0055] Step S1, the base station side establishes the QCI (quality of service level identification) of the bearer according to the UE, and selects the DRX initial parameter to send to the UE, enables the DRX function of the UE, sets the counter T1 for counting the number of times the InactivityTimer (idle timer) is started, and clears T1 0, go to step S2;
[0056] Step S2: After clearing T1 to 0 at the starting point of each DRX cycle, the base station starts counting the number of InactivityTimer starts T1 in this cycle, and enters step S3;
[0057] Step S3, after the DRX cycle ends, determine the adjustment scheme of OnDurationTimer according to the value of T1 in step S2;
[0058] If T1<=Th1, reduce the length of OnDurationTimer and InactivityTimer, and enter step S4;
[0059] If Th3>=T1>Th2, increase the length of OnDurationTimer and...
Embodiment 2
[0072] The system embodiment 2 of the present invention and the method embodiment 1 belong to the same technical concept. For the content not described in detail in the system embodiment, please refer to the method embodiment.
[0073] Such as Figure 4 As shown, a system for adjusting DRX parameters in LTE according to the present invention includes a base station and a UE;
[0074] The base station includes:
[0075] The configuration unit is used for the base station side to establish the QCI of the bearer according to the UE, and select the DRX initial parameter to send to the UE, enable the DRX function of the UE, set the counter T1 for counting the number of InactivityTimer starts, clear the timer T1 to 0, and enter the next unit;
[0076] The statistical unit is used for the base station side to start counting the number of InactivityTimer starts T1 in this cycle after clearing T1 at the starting point of each DRX cycle, and enter the next unit;
[0077] The first adj...

Abstract
The invention discloses a method and system for adjusting a DRX parameter under LTE. The method comprises the steps: S1, building a carried QCI at a base station side according to UE, selecting a DRX initial parameter and transmitting the DRX initial parameter to the UE, starting a DRX function of the UE, and setting a counter T1 for counting the starting times of a spare timer; S2, starting to count the starting times T1 of the spare timer in a period at the base station side after T1 is cleared as zero at the starting point of each DRX period; S3, determining an adjustment scheme for a continuous timer according to the value of T1 after the DRX period; S4, determining an adjustment scheme of the DRX parameters according to the adjustment scheme for the continuous timer. According to the invention, the method can adjust the DRX parameters according to the data amount of the UE and the adjustment condition of the UE, better prevents the unreasonable DRX parameters caused by the changes of the adjustment condition of the UE, and achieves a purpose of DRX power saving to a greater extent when large time delay happens to the UE or the power saving effect is not good.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, the present invention relates to a method and system for adjusting DRX parameters in LTE. Background technique [0002] In LTE, in order to solve the problem of high power consumption of terminals, DRX (Discontinuous Reception, discontinuous reception) is proposed. The UE (UserEquipment, user terminal) stops monitoring the PDCCH (PhysicalDownlinkControlChannel, physical downlink control channel) channel for a period of time to achieve the purpose of power saving. [0003] DRX is divided into two types, IDLEDRX, that is, DRX when the UE is in the IDLE state. When in the IDLE state, the UE only needs to monitor the call channel and the broadcast channel, and as long as the fixed cycle is defined, the purpose of discontinuous reception can be achieved; ACTIVEDRX, That is, when the UE is in the DRX state of RRC-CONNECTED, the UE stops listening to the PD...
