Problems solved by technology

In the LR-WPAN adopting the star network mode, it is easy to cause broadcast frame response conflicts, which will cause the coordinator to fail to receive the response from the RFDs that need to be controlled, and will also cause RFDs that do not need to be controlled to wake up, increasing power consumption, and unable to to save energy

Embodiment Construction

[0058] In order to make the above objects, features and advantages of the embodiments of the present invention more comprehensible, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0059] see figure 1 , which is a flow chart of a method for waking up devices in batches provided by an embodiment of the present invention, which is used in an LR-WPAN in a star networking mode, and the method includes:

[0060] 101. The coordinator generates a wake-up broadcast frame, the wake-up broadcast frame includes a wake-up indication field, and the wake-up indication field is used to indicate that multiple devices in the LR-WPAN remain in the running state;

[0061] When the coordinator sends a wake-up broadcast frame, other devices in the LR-WPAN except the coordinator will receive the wake-up broadcast frame. In the embodiment of the present invention, the wake-up broadc...

Abstract

Embodiments of the present invention disclose a method for waking up devices in batches. The method includes: generating, by a coordinator, a wake-up broadcast frame, where the wake-up broadcast frame includes a wake-up indication field, which is used to instruct multiple devices in an LR-WPAN to keep in a running state; and sending, by the coordinator, the wake-up broadcast frame at a time interval T2 within duration T1. According to technical solutions of the present invention, the coordinator can wake up some devices directionally by using the wake-up indication field in the wake-up broadcast frame. In this way, resource utilization and wake-up efficiency of the coordinator are improved, so that channel utilization and performance of the LR-WPAN are improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and device for waking up devices in batches. Background technique [0002] Low-rate wireless personal area network (LR-WPAN for short) refers to using the same wireless channel in an area and following Institute of Electrical and Electronics Engineers (IEEE) 802.15. A collection of a group of devices that communicate with each other according to 4 standards, also known as IEEE802.15.4 network. The IEEE 802.15.4 standard specifies the physical layer and media access control of LR-WPAN. [0003] Devices in the LR-WPAN are classified into full-function devices (full-function device, FFD for short) and reduced-function devices (reduced-function device, RFD for short), based on communication capabilities. Between FFDs, FFDs and RFDs can communicate directly; RFDs cannot communicate directly, and RFDs can only communicate with FFDs and forward data through FFDs. Ea...
