Embodiment Construction

[0017] In order to describe the method of the present invention more clearly, the implementation of the present invention will be specifically introduced below with reference to the accompanying drawings.

[0018] Using extended DRX in idle mode is one of the candidate solutions for UEPCOP. The feature of adopting the extended DRX solution in idle mode is to maximize the DRX cycle in idle mode so that the UE saves power consumption when waking up and listening to a potential paging channel. However, there are two defects caused by the direct extended DRX: the paging transmission cycle is adjusted with the extended DRX cycle. In this way, a longer paging cycle increases the possibility of retransmission of the paging message; if the DRX cycle lasts for a long time, it takes longer to wait for retransmission of the paging message. For example, assuming that the paging cycle is 1 hour, if the paging message is not sent successfully due to some reasons, the server still needs to ...

Abstract

The invention discloses a 3GPP-based MTC terminal energy-saving method through a self-adaptive mixed DRX mechanism, and relates to power consumption optimization exclusive for MTC. Most MTC terminals send a little information non-frequently and are lower in time delay sensitivity, but are not convenient to charge and replace batteries like H2H (human-to-human) communication, and most batteries are disposable. Aiming at the characteristics and according to requirements proposed by 3GPPR12 for MTC equipment energy consumption, an effective MTC terminal energy-saving method is created. According to the method, the self-adaptive mixed DRX mechanism combines extended DRX and normal DRX, not only can the DRX cycle be extended effectively aiming at QoS (quality of service) requirements of different applications, and the dormant period of the MTC equipment is prolonged so as to prolong the service life of equipment batteries, but also the failure frequency for paging retransmission can be reduced effectively.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method for energy saving of a base terminal. Background technique [0002] With the rapid development of the Internet of Things, Machine Type Communication (MTC) has become the research focus of various standard organizations. 3GPP is committed to studying the use of LTE-A wireless system network to carry MTC communication. The recent 3GPPR12 version focuses on the optimization of MTC terminal power consumption and its standards. R12 proposes the following scenarios for energy saving of MTC terminals: (1) M2M devices similar to sensors, these sensors powered by batteries are the main source of power consumption. If you can't recharge or replace the battery, the battery and life on a lot of devices determines the life of the device. (2) With the increase of a wide range of applications (such as smart phone APP or MTC application), the 3GPP system needs to provi...
