Problems solved by technology

[0019] 1) In order to save power, WLAN terminals need to keep turning off and on the wireless transceiver. Since the turning off and on of the wireless transceiver cannot be automatically controlled by the network side, services that need to deliver data, such as instant messages and advertisements, cannot implementation, which greatly limits network functionality
[0020] 2) The AP caches the data sent by other data sources when the wireless LAN terminal is in the Sleep state, but for the AP that focuses on wireless access, the processing capability and storage space are limited, which cannot meet the needs of large-scale data caching; moreover, when When multiple WLAN terminals enter the power-saving state, limited by the processing capability and storage space, the AP will continuously discard the data of the WLAN terminals, resulting in multiple retransmissions of service packets and frequent packet loss and retransmission, which not only reduces the The network efficiency is greatly reduced, and the user experience is also greatly reduced. Therefore, this method cannot meet the needs of large-volume data caching

Embodiment Construction

[0068] The basic idea of ​​the embodiment of the present invention is: the WLAN terminal receives and executes the online and offline strategy formulated by the online status server, and notifies the online status server of its own status change after its own status is transferred to online or before it is about to transfer to offline; online data caching The server receives the notification of the online / offline status of the wireless LAN terminal, and after the wireless LAN terminal goes offline, caches the data sent by each data source to the wireless LAN terminal; after the wireless LAN terminal turns online, the online data caching server Send the buffered data to the wireless local area network terminal.

[0069] In the embodiment of the present invention, the execution of the online and offline strategy means that the wireless local area network terminal changes its own online / offline status according to the online and offline strategy formulated by the online status ser...

Abstract

Disclosed is a system for keeping a wireless local area network terminal online all the time, comprising: a wireless local area network terminal, configured to receive and execute an online and offline policy formulated by an online-state server, and notify the online-state server of its state change after its state is turned to online or before its state is to be turned to offline; the online-state server, configured to formulate the online and offline policy and send it to the wireless local area network terminal; and an online data buffering server, configured to receive a notification about an online / offline state of the wireless local area network terminal, buffer, after the wireless local area network terminal goes offline, data that is sent by various data sources to the wireless local area network terminal, and send the buffered data to the wireless local area network terminal after the wireless local area network terminal goes online. Further disclosed are a method and a server for keeping a wireless local area network terminal online all the time.

Description

technical field [0001] The present invention relates to the field of wireless local area network (Wireless Local Area Network, WLAN) communication, in particular to a system and method for keeping a wireless local area network terminal online, and a server. Background technique [0002] The large-scale development of WLAN has made smart wireless LAN terminals with mobility and portability more and more popular. However, due to the high power consumption of the WLAN module inside the smart wireless LAN terminal, users have to turn off the WLAN module for a long time to save power. Purpose. [0003] At present, in order to carry out more services and keep the WLAN terminal online all the time, the 802.11 standard defines a Power Save (PS) function. figure 1 It is a schematic diagram of the PS process in the 802.11 standard, such as figure 1 As shown, the PS process includes the following steps: [0004] Step 101: the wireless local area network terminal associates with an a...
