Embodiment Construction

[0133]In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0134] In this example, the eNB periodically adjusts the DRX parameters of the UE by making a priori judgment on all service characteristics of the UE, so as to achieve a balance between power saving and sensitivity, so as to achieve UE power saving and user The purpose of paying equal attention to QoS experience.

[0135] Such as figure 1 As described above, a method for adjusting DRX parameters in a long-term evolution system is applied to an evolved base station, and for each UE, the following operations are performed:

[0136] Step 10, collecting all historical service d...

Abstract

Disclosed are a method and an eNB (evoluted Node B) for adjusting DRX (discontinuous reception) parameters in a long term evolution system. The method is applied in an evolution-type base station, and includes aiming at each user equipment (UE), executing the following operations: collecting all historical service data conditions of the UE in some past time; calculating adjusting values to current noncontinuous receiving (DRX) parameters according to collected historical service data; adjusting the DRX parameters currently used by the UE according to the adjusting values. By adopting the method, the eNB can predict near-term service characteristics of the UE, calculate the DRX parameters suitable for service types of the UE and adjust the DRX parameters of different UE on the basis of monitored historical service data of the UE so as to achieve the objectives of electricity saving and good QoS (quality of service) guarantee of the UE, so that better user experience is acquired.

Description

technical field [0001] The present invention relates to the field of long term evolution (Long Term Evolution, referred to as LTE) proposed by 3GPP (The 3rd Generation Partnership Project, third generation partnership project), especially relates to a kind of DRX (Discontinuous Reception, discontinuous reception) in LTE system ) parameter adjustment method and eNB (evolved Node B, evolved base station). Background technique [0002] The broadband wireless high-speed data transmission provided by LTE adopts a short frame design of 1 ms, which means that UE (User Equipment, user equipment) needs to listen to the Physical Downlink Control Channel (PDCCH for short) every frame, so it will consume rapidly The battery level of the UE. In LTE, a mechanism of DRX is proposed, the purpose is to allow the UE without data transmission to turn off the wireless receiver according to the period stipulated in the protocol, so as to achieve the purpose of power saving. [0003] The DRX me...
