Problems solved by technology

[0017] However, the DRX mechanism of the current LTE system does not consider the change of the number of data packets in the service queue established by the network side for the user equipment at all, so it is impossible to dynamically and adaptively adjust the parameters in the DRX mechanism according to the number of data packets, for example Length of sleep period, length of deactivation timer, etc.

Embodiment Construction

[0115] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0116] According to the method for dynamically controlling discontinuous reception of user equipment provided by the present invention, it mainly includes the following steps:

[0117] Step 1: When the user equipment initially establishes a connection, the network side notifies it of the initial values ​​of the parameters used in the discontinuous reception process through downlink signaling;

[0118] Step 2: During the service connection of the user equipment, after the end of each scheduling time, the network side waits in the service queue established for the user equipment according to the discontinuous reception process performed by the user equipment at the previous time (that is, the last determined) The number of ...

Abstract

The invention discloses a method and a device for dynamically controlling discontinuous reception of UE, the method comprising: when the UE initially establishes a link, the network side informs the UE to execute parameters to be used in a discontinuous reception process through a downlink signaling; during a service linking of the UE, after the end of each scheduling moment, the network side determines how to dynamically adjust the discontinuous reception process of the UE according to a discontinuous reception process executed by the UE at a preceding moment and the number of data packets to be transmitted in the service queue created for the UE; the network side sets a DRX mark for instructing the UE to change its discontinuous reception process according to the method and the result of determining how to adjust the discontinuous reception process of the UE, and transmits the set DRX mark to the UE in an open state of the receiver of the UE; the UE executes a different discontinuous reception process according to the received DRX mark and self-adaptively adjusts the parameters in the discontinuous reception process.

Description

technical field [0001] The present invention relates to a discontinuous reception (Discontinuous Receive, DRX) technology, in particular to a method and device for dynamically controlling discontinuous reception of user equipment. Background technique [0002] With the rapid development of mobile communication technology, the processing capability of mobile terminals is rapidly enhanced, and the functions provided are rapidly increased. While the future mobile communication system provides higher spectrum utilization, higher data rate, and more colorful multimedia services, the problem of power consumption of its terminals is also more severe. In particular, the access network of the future mobile communication system will be based on IP technology for data transmission, and the burst characteristics of IP data packets and the sharing characteristics of transmission channels among users make the data arriving at user equipment discontinuous. Therefore, how to It is more imp...
