Embodiment 1

[0032] Such as figure 1 As shown, Embodiment 1 provides a method for saving power of a wireless access point device, and the method includes the following steps:

[0033] 101. Receive a connection establishment request message from a first wireless terminal, and establish a connection with the first wireless terminal;

[0034] 102. When the number of wireless terminals connected to the wireless access point device reaches a preset maximum number of connections after establishing a connection with the first wireless terminal, perform at least one of preset power consumption reduction operations;

[0035] Among them, the above preset power consumption reduction operations include:

[0036] Prolong the sending period of the beacon frame, set the first power to send the beacon frame, stop responding to any message sent by the unconnected wireless terminal, and according to the wireless LAN channel allocated to the wireless terminal connected to the wireless access point device T...

Embodiment 2

[0040] This embodiment 2 provides a method for saving power of a wireless access point device, which is an improvement on the basis of embodiment 1. In this embodiment, the wireless access point device corresponding to the WiFi wireless local area network is WiFi An access point device (AP) is taken as an example for illustration, where a wireless terminal connected to the AP is called a STA (Station, station). The wide area network may adopt GSM (Global System for Mobile Communications, Global System for Mobile Communications), UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System), LTE (Long Term Evolution, Long Term Evolution), WiMAX (Worldwide Interoperability for Microwave Access (Global Microwave Interconnection Access) wireless communication technology macro cellular mobile communication network, or fixed communication network or optical fiber communication network using IP communication technology.

[0041] It should be noted that thi...

Embodiment 3

[0106] Such as Figure 5 As shown, this embodiment provides a device for saving power of a wireless access point device, and the device includes:

[0107] A connection module 301, configured to receive a connection establishment request message from a first wireless terminal, so as to establish a connection between the wireless access point device and the first wireless terminal;

Abstract

Disclosed are a power saving method and a device for a WiFi access point apparatus belonging to the technical field of wireless communication. In the present invention, when reaching a preset maximal connection number of the wireless access point apparatus, changing the working mode of the present wireless access point apparatus, extending the beacon frame transmission period of the wireless access point apparatus, transmitting the beacon frame with a maximal power used by wireless terminals during communications, wherein the wireless terminals are connected with the wireless access point apparatus, stopping responding to any messages transmitted from unconnected wireless terminals, and on the basis of wireless local network channel bandwidth distributed to the wireless terminals connected with the wireless access point or wide area network communication bandwidth obtained by the wireless access point apparatus, determining the sleep time of the wireless local network communication module of the wireless access point apparatus, so as to reduce the power consumption and extend the use time of portable wireless access point apparatus.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for saving power of WiFi access point equipment. Background technique [0002] The wireless access point device can use wireless communication technology to connect to the wireless local area network, such as the current WiFi (Wireless Fidelity, wireless fidelity) access point device, Bluetooth device, etc., wherein the AP ( Access Point, access point) as an example, most of the current wireless access devices are deployed in a fixed deployment mode, and the mains power supply is used. [0003] Recently, a portable wireless access point device that is easy to carry has appeared. On the one hand, this device acts as a terminal device of the wide area network to communicate with the wide area network. On the other hand, it can also provide access services for wireless terminal devices in the local area network. Such wireless access point devices ar...
