Description of drawings
Fig. 1 is the wireless LAN card structured flowchart.Wherein wireless LAN card is made up of wireless network card host side interface, netting twine LAN card chip, power supply chip, AFE (analog front end) device, radio frequency chip, antenna, PCB base plate.
Embodiment
The invention provides a kind of wireless LAN card power consumption control method, by system-level whole wireless network card equipment, WLAN (wireless local area network) card chip, radio frequency chip are carried out power managed and control by different level, in the hope of realizing reducing the purpose of wireless LAN card equipment work power consumption.
As shown in Figure 1, wireless network card equipment is made up of wireless network card host interface, netting twine LAN card chip, power supply chip, AFE (analog front end) device, radio frequency chip, antenna, PCB base plate wireless LAN card.The wireless network card host side system-level to whole wireless network card equipment, WLAN (wireless local area network) card chip, radio frequency chip carries out power managed and control by different level, wherein: the wireless network card host side can be carried out power operation to whole netting twine network card equipment, wireless network card host side control WLAN (wireless local area network) card chip enters low power mode of operation, the wireless network card host side can be turn-offed powered operation to radio frequency chip also can make radio frequency chip enter the stand-by operation state, and can make whole netting twine network card equipment, WLAN (wireless local area network) card chip, and radio frequency chip reverts to normal operating conditions from the low-power consumption operating state.
Be in standby in the wireless network card host side, hang up, during resting state, at this moment host side does not require the wireless network card equipment work, the wireless network card host side can be by the supply lines in main frame and the wireless network card equipment interface with the wireless network card device powers down, thereby reach wireless network card equipment low-power consumption work purpose, when the wireless network card host side knows that from operating system main frame is from standby, hang-up or dormancy operating state switch to normal operating conditions, at this moment host side can require the wireless network card equipment work, the wireless network card host side can continue to the wireless network card power devices by the supply lines in main frame and the wireless network card equipment interface, thereby reaches the purpose of recovering the wireless network card normal operating conditions.
Below use energy-conservation polling mechanism mode to communicate by letter and the specific embodiment that uses 802.11U-APSD or WiFi WMM-PS working method to communicate by letter illustrates the concrete implementing method of the present invention with regard to site-local and wireless access hotspot device.
Site-local uses energy-conservation polling mechanism to communicate by letter with the wireless access hotspot device and when not having communication service, at first, site-local wireless network card host side is controlled the network interface card power supply chip by WLAN (wireless local area network) card chip, thereby radio frequency chip is cut off the power supply, afterwards, the clock control device of site-local wireless network card host side notice WLAN (wireless local area network) card chip stops to provide clock for WLAN (wireless local area network) card chip work, thereby WLAN (wireless local area network) card chip enters the low-power consumption working method, reach wireless network card equipment low-power consumption work purpose, site-local uses energy-conservation polling mechanism to communicate by letter with the wireless access hotspot device, and never communication service is about to transfer to when communication service is arranged, the WLAN (wireless local area network) card chip of wireless network card equipment end can know that in advance which has communication constantly at takes place according to energy-conservation polling mechanism rule of communication, before this moment, WLAN (wireless local area network) card chip can produce the notice that is about to communication service by the mode that produces interruption or generation interrupt descriptors, notice site-local wireless network card host side, after site-local wireless network card host side is received this notice, at first, site-local wireless network card host side can notify the clock control device of WLAN (wireless local area network) card chip to begin to provide clock for WLAN (wireless local area network) card chip work, thereby make network card equipment enter normal operation mode, afterwards, site-local wireless network card host side is controlled the network interface card power supply chip by the WLAN (wireless local area network) card chip of operate as normal, thereby begin radio frequency chip is powered, thereby reach the purpose of recovering the wireless network card normal operating conditions.
When site-local and wireless access hotspot device are used 802.11U-APSD or WiFi WMM-PS working method to communicate by letter and are not had communication service, at first, site-local wireless network card host side is controlled radio frequency chip by WLAN (wireless local area network) card chip, make radio frequency chip enter the stand-by operation mode, afterwards, the clock control device of site-local wireless network card host side notice WLAN (wireless local area network) card chip stops to provide clock for WLAN (wireless local area network) card chip work, thereby WLAN (wireless local area network) card chip enters the low-power consumption working method, reach wireless network card equipment low-power consumption work purpose, site-local wireless network card host side can be paid the communication service of getting off according to upper layer application and be judged when site-local and wireless access hotspot device use 802.11U-APSD or WiFi WMM-PS working method to communicate by letter, when communication service is arranged, when communication service is arranged, at first, site-local wireless network card host side can notify the clock control device of WLAN (wireless local area network) card chip to begin to provide clock for WLAN (wireless local area network) card chip work, thereby make network card equipment enter normal operation mode, afterwards, site-local wireless network card host side is controlled radio frequency chip by the WLAN (wireless local area network) card chip of operate as normal, thereby make radio frequency chip revert to normal operating conditions, reach the purpose of recovering the wireless network card normal operating conditions from holding state.
More than disclosed only be several specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any those skilled in the art can think variation all should drop in protection scope of the present invention.
