A terminal power saving method and device

Abstract

Embodiments of the present invention provide a terminal power saving method and device, which relate to the field of communication, and can reduce terminal power consumption by setting a reasonable timeout time of a timer. The method comprises: when determining that the terminal enters an idle state, obtaining the service packet lengths of k consecutive historical tasks on the terminal and the timeout time of the activation timers of the k historical tasks; calculating the k historical tasks according to the service packet lengths of the k historical tasks The average service package length of the current task; when the average service package length of the current task is greater than the average service package length of the historical task, the adjustment coefficient is calculated according to the average service package length of the current task and the average service package length of the historical task; according to k historical tasks The overtime of the activation timer of the task and the adjustment coefficient calculate the overtime of the target activation timer of the current task; start the target activation timer; when the target activation timer expires, determine that the terminal enters the low power consumption mode PSM. The embodiment of the present application is applied to terminal power saving.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and in particular, to a terminal power saving method and device. Background technique [0002] The narrowband internet of things (NB-Iot) based on the cellular network is an IoT technology based on the evolution of the long term evolution (LTE) standard protocol of the third generation partnership project (3rd generation partnership project, 3GPP). It is mainly for IoT application scenarios with medium and low rates, deep coverage, low power consumption, and large connections. Support enhanced discontinuous reception (eDRX) and low power consumption mode (power saving mode, PSM) and other power saving technologies, so as to reduce the power consumption of the terminal. [0003] PSM is a technology introduced by 3GPP R12. Its principle is that the user terminal and the mobile management entity (mobile management entity, MME) determine an activation timer (T3324 timer) through non-a...

Problems solved by technology

[0004] Among them, during the working process of NB-IoT, the terminal and MME negotiate to determine the duration of the activation timer through the non-access stratum message. The duration of the activation timer determined by this method is longer, so that the terminal enters the PSM from the idle state. The duration of the timer is longer, and when the terminal consumes a lot of power and the duration of the activation timer is longer, it will cause a large power consumption of the terminal
