Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] The present invention proposes a PSM and EDRX power-down sleep method, such as figure 1 , including the following steps:

[0024] S1. Establish the event list of the events controlled by the timer that has been started and the event list that will be generated after the execution of the task and has not been delivered to the judgment module;

[0025] S2. The terminal judges whether the condition of PSM or EDRX power-down sleep is met according to event...

Abstract

The invention relates to a mobile communication system, in particular to a PSM and EDRX power-down sleep method and a terminal thereof, and the method comprises the steps: building an event list of events controlled by a started timer and an event list which is generated after an executed task runs and is not transmitted to a judgment module; if PSM or EDRX power-down sleep conditions are met, traversing an event list of events controlled by the started timer, and if the timer involved in the event list is started and the remaining time length of the timer is smaller than a power-down sleep time threshold, continuing to be in a non-power-down state; otherwise, traversing all tasks of the current baseband, and if the tasks which are still generated after the executed tasks run and are not transmitted to the event list of the judgment module exist in the tasks, continuing to keep a non-power-down state; otherwise, the power supply control module executes power-down sleep; according to the invention, power failure and power-on of the terminal and unnecessary expenditure of the Internet of Things terminal are greatly avoided, and a better low-power-consumption effect is obtained.

Description

technical field [0001] The invention relates to a mobile communication system, in particular to a PSM and EDRX power-down sleep method and a terminal thereof. Background technique [0002] For IoT systems, low power consumption is a very important indicator. In order to meet its 10-year standby requirement, the functions of power saving mode (power saving mode, PSM) and extended idle-mode DRX cycle (extended idle-mode DRX cycle, EDRX) are introduced from the protocol point of view. [0003] For IoT terminals that support the PSM function, they carry PSM information in the attach request (attachment request) or taurequest (tracking area update request), and inform the network that the current corresponding terminal has supported PSM. If the network also supports PSM, then Valid T3324 will be configured in attach accept (attach accept) or tau accept (tracking area update accept). When the terminal receives attach accept or tau accept, T3324 is turned on. When T3324 times out...
