Embodiment 1

[0043] figure 1 A communication system is shown, which includes two interactive communication devices, and WiFi and BT dual connections can be established between the two communication devices. In order to facilitate the distinction, in this embodiment, the communication device on the left side of the figure is called the dormant communication device A, and the communication device on the right side of the figure is called the wake-up communication device B. It should be noted that whether a communication device is a dormant communication device or The communication device as the wake-up end is not fixed, but is determined according to the sleep and wake-up states of the communication device. That is to say, although it is called a dormant communication device, it does not mean that the WiFi of communication device A can only be in a dormant state. It can wake up by itself or be awakened by other devices according to the needs of sending and receiving, so as to switch to the a...

Embodiment 2

[0056] This embodiment is similar to Embodiment 1, mainly based on the WiFi-Bluetooth dual connection communication architecture between the dormant communication device A and the wake-up communication device B in Embodiment 1. In the communication system of this implementation, the communication device B at the awakening end may wake up the communication device A at the dormant end.

[0057] Such as image 3 As shown, in order to wake up the dormant communication device A, in the wake-up communication device B, the second Bluetooth module 22 is configured to send a wake-up signal to the first Bluetooth module 12 through a Bluetooth link. In the dormant communication device A, the first Bluetooth module 12 is configured to receive the wake-up signal through a Bluetooth link.

[0058] The wake-up signal is used to wake up the first WiFi module 11 in a dormant state. The wake-up signal can be a self-defined signal, which is sent to the first Bluetooth module 12 by the second B...

Abstract

The invention discloses a communication equipment and system and a sleep and wake-up method. The communication equipment comprises a first WiFi module, and a first Bluetooth module which is used for sending a connection maintaining signal to the second Bluetooth module of awakening end communication equipment through a Bluetooth link when the first WiFi module is in a dormant state. The connectionmaintaining signal is used for enabling the first WiFi module to be connected with the second WiFi module of the awakening end communication equipment, and / or the connection maintaining signal is used for receiving the awakening signal through the Bluetooth link, and the awakening signal is used for awakening the first WiFi module in a dormant state. According to the invention, when the communication equipment is in a dormant state, the BT link is adopted to transmit the connection maintaining signal so as to maintain WiFi connection; the awakening signal is transmitted through the Bluetoothlink, and the awakened communication equipment does not need to be awakened regularly, so that the power consumption is saved, and awakening can be realized in time; the BT link is used as a whole toeliminate the power consumption of periodically waking up to send and receive the WiFi frame.

Description

technical field [0001] The invention belongs to the field of wireless communication, and in particular relates to a communication device, a system and a dormancy and wake-up method. Background technique [0002] WiFi (a wireless network technology) and Bluetooth (Bluetooth) technology are currently the most widely used wireless connection technologies, and WiFi has the characteristics of high speed, high delay, and high power consumption. BT is suitable for low-speed, low-latency, and low-power consumption scenarios. Although these two technologies can already be integrated in the same wireless communication chip, the WiFi and BT connections still exist independently between two devices that have established a WiFi and BT dual connection. [0003] Most scenarios of WiFi connection run in infrastructure mode (interconnected working mode through AP), that is, one AP (access point), and another or more clients as STA (workstation or station). The AP and STA exchange data thro...
