Problems solved by technology

For the UE that needs to configure DRX when initially entering the RRC connection state, this information is not sufficient
If you have to wait for enough statistical time to calculate the mobility status of the UE, and then configure DRX parameters based on this information, it will cause waste of UE power
[0008] To sum up, the inability of the eNB to obtain accurate distribution characteristics of service data packets leads to large DRX parameter configuration errors, and the UE’s power is wasted due to the inability to obtain the mobile status of the UE in time

Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] In the embodiment of the present invention, the eNB obtains the service data packet distribution characteristics, that is, the data packet arrival rate, from the core network or the UE, and the UE reports the mobile state information to the eNB. The eNB optimizes the configuration of the DRX cycle according to the distribution characteristics of the data packets and the mobile state of the UE, which improves the power efficiency and mobile performance of the UE.

[0033] See attached figure 2 It is a schematic flowchart of a method for adjusting a discontinuous reception cycle, specifically including the following steps:

[0034] In step 201, the eNB determines service activity according to the packet arrival rate of service ...

Abstract

The invention discloses a method for regulating a discontinuous reception cycle. The method comprises the following steps of: determining a service activity by a node B evolved base station (eNB) through a data packet arrival rate of service data; reporting mobile state information to the eNB by user equipment (UE); and configuring a discontinuous reception (DRX) cycle by the eNB depending on the service activity and the mobile state information. Through the application of the embodiment disclosed by the invention, the DRX cycle is precisely configured, waste of UE power is reduced and switching performance is improved.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a method for adjusting a discontinuous reception cycle. Background technique [0002] 3GPP Long Term Evolution (LTE) is the largest new technology research and development project launched by 3GPP in recent years. This technology centered on Orthogonal Frequency Division Multiplexing (OFDM) and Multiple Input Multiple Output (MIMO) can be regarded as "quasi-4G". technology. In order to meet various demand indicators of the advanced international mobile communication system IMT-Advanced (4G), 3GPP has carried out research on the subsequent evolution of LTE technology, namely LTE-Advanced. LTE-Advanced is an evolved version of LTE, using key technologies such as carrier aggregation (Carrier Aggregation), multi-antenna enhancement (Enhanced MIMO), coordinated multi-point transmission (CoMP), relay (Relay) and enhanced interference coordination enhancement (e...
