Definitions
- WiFi Wireless Fidelity
- the WiFi STA can discover the network by sending an active scanning message by receiving a beacon message that is periodically broadcasted by the AP. If a WiFi STA needs to discover the WiFi AP existing in the vicinity as soon as possible, the WiFi STA may broadcast a probe request message (Report request), and carry the corresponding information of the requested one or more WiFi networks, that is, the WiFi AP, in the network probe request message.
- the information identifier indicates that one or more APs that receive the Probe request in the proximity of the WiFi STA will reply to the STA with a probe response message, and include information about the WiFi AP requested by the STA in the probe response message.
- each STA needs to scan multiple channels supported by itself when broadcasting a Probe request, send a Probe request through each channel, and wait to receive a Probe response generated by one or more AP responses in the neighboring area. It can be seen that each Probe request will cause multiple APs in the neighboring area to respond, resulting in multiple Probe responses. Therefore, for a scenario where a large number of STAs perform network discovery at almost the same time, in the network discovery phase, each channel of the STA will spend most of the time for transmitting the network discovery message Probe request and Probe response. It can be seen that the existing WiFi network discovery mechanism will cause a large number of Probe request/response messages to occupy the communication channel used by the STA and the AP, which greatly reduces the channel usage efficiency. Summary of the invention
- an embodiment of the present invention provides a method and an apparatus for discovering a wireless network, so as to reduce a large number of network probe request messages sent by a STA due to network discovery in a wireless network discovery phase, and simultaneously reduce a network probe request message.
- the generated probe response message improves channel usage efficiency.
- An embodiment of the present invention provides a method for discovering a wireless network, including:
- the station listens to the current channel before sending the first network probe request message to the access point;
- the station When the station receives the second network probe request message sent by the other station on the current channel, the station delays sending the first network probe request message, or the station cancels sending the first network probe Request message.
- the embodiment of the invention further provides a site, including:
- a listening module configured to listen to a current channel before sending a first network probe request message to the access point, and trigger a message delay when receiving a second network probe request message sent by another station on the current channel Module
- a message delay module configured to delay sending the first network probe request message
- the message canceling submodule is configured to cancel sending the first network probe request message.
- the network detection request message is not directly sent through the channel to perform active detection of the wireless network, but the current channel is firstly intercepted to determine the current channel. Whether the network probe request message sent by other stations is received, and when the current channel receives the network probe request message sent by other stations, the network probe request sent by the station for network discovery is reduced by delaying the sending of the network probe request message. The message, thereby reducing the probe response message generated by the network probe request message, improving channel usage efficiency.

Detect response messages to improve channel usage efficiency.
- a flow of a method for discovering a wireless network according to an embodiment of the present invention includes the following steps:
- Step 101 The station listens to the current channel before sending the first network probe request message to the access point.
- Step 102 When the station receives the second network probe request message sent by another station on the current channel, the station delays sending the first network probe request message.
- the first network probe request message specifically refers to a network probe request sent by the current station.
- the message, the second network probe request message specifically refers to a network probe request message sent by another one or more stations.
- the network when the station needs to perform the wireless network discovery, the network does not directly send the network probe request message through the channel to perform active detection of the wireless network, but firstly listens to the current channel to determine whether the current channel receives the other station to send.
- the network probe request message when it is found that the network probe request message sent by another station is received on the current channel, reduces the network probe request message sent by the station due to network discovery by delaying the manner of sending the network probe request message, thereby reducing
- the probe response message generated by the network probe request message improves channel usage efficiency.
- the manner in which the station delays sending the first network probe request message refers to: the station sends the first channel sent by one or more other stations on the current channel. a network probe request message, when the station determines that the second network probe request message includes the network information identifier that is to be requested by itself, the preset time period from the receipt of the second network probe request message The first network probe request message is not sent, and waits for receiving a second probe response message sent by the neighboring wireless network access point.
- the preset time refers to the maximum time required for the peripheral wireless network access point to send a probe response message to the site after receiving the network probe request message sent by a certain station.
- the time value may be set by the wireless network access point itself; or set by the site that sends the network probe request message, and the corresponding time value is carried in the network probe request.

- the first network probe request message still needs to be sent after the preset time is reached.
- the station does not receive the second probe response message sent by the neighboring wireless network access point within the preset time, and does not receive the message for wireless network discovery, and then arrives at the pre- After the time is set, the first network probe request message still needs to be sent.
- the station that performs network discovery needs to listen to whether there is a network probe request message sent by another station on the channel before sending the network probe request message.
- the station needs to parse each physical layer frame received and obtain a MAC (Media Access Control) layer frame contained in the physical layer frame, and pass the frame in the MAC layer frame header.
- the type information determines whether the current MAC frame is a network probe request message, however, existing implementations may cause the station to consume more power.
- the site adds indication information at the head of the physical frame of the sent message, where the indication information is used to indicate that the current message is a network probe. Request message. Specifically, the indication information is used to indicate whether the data part of the physical layer frame includes a Probe request of the MAC layer. In an actual application, the indication information may occupy one or more Bit bits of the physical frame header, and the determined value indicates whether the data part of the physical frame includes a Probe request of the MAC layer.
- the site only needs to parse each The header portion of the physical layer frame can be used according to the indication information contained therein to know whether the physical layer frame includes a Probe request, thereby avoiding further parsing the data portion of the physical layer frame in order to obtain the included MAC layer frame content type. Operation, reducing the power consumption of the site.
- the station passes the indication information of the header portion of a physical layer frame, and determines that the data portion of the physical layer frame includes a Probe request frame of the MAC layer, the Probe request frame needs to be obtained.
- the content of the request information included in the request still needs to further parse the data portion of the physical layer frame to obtain the request information contained in the MAC layer frame.
- the overall scheme will be described in detail below through specific examples.
- the AP is an access point
- STA1 and STA2 are two sites that perform network discovery in the AP coverage area.
- STA1 In order to discover the WiFi network corresponding to the AP as soon as possible, STA1 is triggered to actively scan the WiFi network.
- the specific process is as follows: The site management entity (SME) triggers the MAC layer to send a network probe request message Probe request through a scan request message (Scan request), and the site management entity carries a probe delay parameter in the Scan request message, indicating that the MAC layer is sending an active scan. Before the message Probe request, you need to wait for the time period specified by probe delay.
- each STA needs to first monitor whether the channel is idle before using the channel to send a message, and starts the backoff time window when the channel is found to be idle, and continues to monitor the channel in the backoff time window, if Until the end of the backoff window, the channel is still idle and the Probe request is sent.
- STA1 initiates a scan request by the site management entity at time t1, wherein the time specified by the Probe delay parameter carried in the Scan request and the backoff time are t3-tl, where the backoff time is relative to the Probe delay.
- the time specified by the parameter is negligible. That is, STA1 will send a Probe request at time t3.
- the Probe sends the Probe request, it usually carries one or more network information identifiers requested by itself in the Probe request.
- the STA1 that is going to perform active network scanning receives other information during the (t3-tl) channel listening period Probe request sent by STA (such as STA2) (assuming no other messages can be received for network discovery during the period), as shown in Figure 2, it is assumed that STA1 receives the Probe request sent by STA2 at time t2, STA1 can further The Probe request message is parsed to obtain the information of the request carried by the STA2, and it is determined whether the network information identifier requested by the STA2 includes the network information identifier that the STA1 itself requests.
- the STA1 delays sending the Probe request message and waits. Receive the Probe response message that the AP responds to STA2; if not, STA1 needs to continue to send the Probe request message before the time point t3.
- STA1 receives the AP direction at time t4.
- the probe response sent by STA2 can reduce the probe request message sent by STA1 in the network discovery phase and the resulting probe response sent by the AP to STA1.
- the AP needs to respond to send a probe response within a preset time.
- the preset time is (t5-t2).
- STA1 is in the response probe response time specified by the AP (before t5), it has not received the probe response from the AP to STA2, and has not received other messages that can be used for network discovery (such as: If the access point AP broadcasts the Beacon message periodically, the AP actively sends or responds to other STA's probe response messages, etc., STA1 still needs the competitive channel to send the Probe request.
- STA1 does not receive other messages that can be used for network discovery during the (t3-tl) channel listening period (such as a Beacon message periodically broadcast by the access point AP, AP active transmission or Responding to the probe response message of other STAs, etc.), but if other messages that can be used for network discovery are received during the channel listening period, such as the Beacon message periodically broadcast by the access point AP, the AP actively sends or responds to the probe of other STAs.
- the response message, etc., and determining that the message contains the network information that it wants to request, that is, if the WiFi network that satisfies the requirement is found, STA1 may cancel the sending of the Probe request.
- STA1 receives a Probe request sent by multiple other STAs before the time point t3, STA1 finds the network information identifiers of multiple STA requests after parsing the Probe requests, if found The union of the network information identifiers of the requests carried in the multiple Probe requests includes the network information identifiers to be requested by the STA1, and the STA1 may also delay sending the Probe request message and wait for the Probe response of the AP to respond to the STAs.
- STA1 After receiving the Probe request of STA2 at time t2, STA1 does not receive the Probe response of the AP to STA2 before t5, but STA1 receives one or the AP sends to other STAs (non-STA2). If there are multiple Probe responses, and it contains the network information that STA1 itself wants to request, STA1 cancels the sending of the Probe request message.
- STA1 still needs to be at t3.
- STA1 does not receive the Probe request of STA2 during the (t3-tl) channel listening period, but STA1 receives other messages that can be used for network discovery, if it contains the network information that STA1 itself wants to request, STA1 cancels Send the Probe request, otherwise, STA1 still needs to send the Probe request before the t3 time.
- the network when the station needs to perform wireless network discovery, the network does not directly send a network probe request message through the channel to perform active detection of the wireless network, but firstly listens to the current channel to determine whether the current channel is received.
- a network probe request message sent to another station when it is found that the network probe request message sent by another station is received on the current channel, the network probe request message sent by the station due to network discovery is reduced by delaying the sending of the network probe request message. Therefore, the probe response message generated by the network probe request message is reduced, and the channel use efficiency is improved.
