Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
embodiment mono-:
A kind of method that the embodiment of the present invention one provides wireless network dormancy and waken up, referring to Fig. 1, described method comprises:
101. sense terminals equipment data transmit-receive state in the given time.
The data transmit-receive state of terminal equipment comprises four kinds of states, is respectively: (1) neither receives data, does not also send data; (2) do not send data, but receive data; (3) send data, but do not receive data; (4) both receive data, also sent data.The present invention only operates terminal equipment when the first and the second state, and when the third and the 4th kind of state, terminal equipment is not carried out to any processing.
102a., when terminal equipment neither receives data within first scheduled time, while also not sending data, joins terminal equipment in deep-sleep list, and sends deep-sleep list to terminal equipment by heartbeat packet.The wireless flow of access point collection terminal equipment and radio receiving transmitting module state, when finding that the long-time section of terminal equipment is without receiving the data that send, do not receive these terminal equipment valid data of transmission with access point, access point is indicated this terminal equipment penetration depth resting state, deep-sleep list is placed in heartbeat packet extend information, then sends heartbeat packet to terminal equipment.
103a. judges whether to wake up deep-sleep terminal equipment according to the situation of current network communication, and judgment result is that while being, the terminal equipment of deep-sleep that need are waken up joins in the first scheduling wake-up list.Access point is by the transmitting-receiving flow of each terminal equipment of periodic statistics wireless network, analyze the type that this terminal equipment sends bag and receives bag simultaneously, determine the packet radio that lower timeslice may occur, finally according to statistics, analysis result, to registering penetration depth resting state terminal equipment, carry out communicated prediction, judge whether to wake terminal equipment up, the terminal equipment simultaneously needs being waken up, adds in the first scheduling wake-up list.
104a. sends the first scheduling wake-up list to terminal equipment every second scheduled time by heartbeat packet.The first scheduling wake-up list is placed in heartbeat packet extend information, then every second scheduled time, sends heartbeat packet to terminal equipment.
102b. does not send data when terminal equipment within the 3rd scheduled time, but while receiving data, terminal equipment is joined in standard sleep list, and send standard sleep list to terminal equipment by heartbeat packet.The wireless flow of access point collection terminal equipment and radio receiving transmitting module state, when finding that the long-time section of terminal equipment does not send data and receives only data, access point is indicated this terminal equipment Engage of standard resting state, standard sleep list is placed in heartbeat packet extend information, then sends heartbeat packet to terminal equipment.
103b. judges whether to wake up standard sleep terminal equipment according to the situation of current network communication, and judgment result is that while being, the terminal equipment of standard sleep that need are waken up joins in the second scheduling wake-up list.Access point is by the transmitting-receiving flow of each terminal equipment of periodic statistics wireless network, analyze the type that this terminal equipment sends bag and receives bag simultaneously, determine the packet radio that lower timeslice may occur, finally according to statistics, analysis result, to registering Engage of standard resting state terminal equipment, carry out communicated prediction, judge whether to wake terminal equipment up, the terminal equipment simultaneously needs being waken up, adds in the second scheduling wake-up list.
104b. sends the second scheduling wake-up list to terminal equipment by heartbeat packet.The second scheduling wake-up list is placed in heartbeat packet extend information, then sends heartbeat packet to terminal equipment.
Alternatively, as shown in Figure 2, before step 101, also comprise step 100.
100. send the real-time time of access point time source or available machine time to terminal equipment by heartbeat packet.
