The network device includes a router, an Access Point (AP), and other devices, and in the following embodiments, the present invention is described in detail by taking the access point as an example, but the present invention is not limited thereto.
Fig. 1 is a flowchart of a method for negotiating a broadcast-aware process according to an embodiment of the present invention. As shown in fig. 1, the method for negotiation of broadcast-aware process includes the following steps:
s101, an access point broadcasts a broadcast message (such as beacon message) containing a Sensing process information element, wherein the Sensing process information element contains a broadcast Sensing process identifier and Sensing process parameters.
In some embodiments, the access point may also include the aware process information element Sensing element in a probe response message (e.g., a probe response message) in response to a probe request message (e.g., a probe request message) sent by the terminal, or a connection response message (e.g., an association response message) in response to a connection request message (e.g., an association request message) sent by the terminal. Therefore, the terminal can obtain the Sensing process information element from the broadcast message, or the probe response message, or the connection response message. And the Sensing element contained in the broadcast message, the probe response message and the connection response message may be one or more.
Illustratively, the Sensing process parameters included in the Sensing process information element include duration of a broadcast Sensing process, sending time of a next broadcast message including the Sensing process information element, sending time of a next Sensing data packet, transmission bandwidth of the Sensing data packet, and a channel for sending the Sensing data packet.

In some embodiments, the Sensing element may further include an interval between two Sensing packet transmissions, and in this case, the Sensing element setting is shown in table 2. Alternatively, the interval between two sensing packet transmissions may be set to less than half of the broadcast message transmission interval.

S102, the terminal sends a perception establishing request message to the access point, and the perception establishing request message indicates that the terminal requests to join a broadcast perception process. Optionally, the sensing establishment request message includes a broadcast sensing process identifier requested to be added by the terminal or suggested sensing process information.

And S103, after receiving the perception establishment request message, the access point sets a response result according to the perception establishment request message, if the terminal is allowed to join the broadcast perception process, the response result is set to indicate that the request is accepted, otherwise, the response result is set to indicate that the request is rejected.
Optionally, the setting, according to the broadcast sensing process identifier that the terminal requests to join or the suggested sensing process information included in the sensing establishment request message, a response result includes: after receiving the perception establishment request message, if the Negotiation type value is 1, the access point searches whether a Broadcast perception process identifier corresponding to the parameter value exists locally according to the Broadcast sensing ID, if so, the access point sets the parameter status code value to accepted, and indicates to accept the request, and if not, the access point sets the parameter status code value to returned, and indicates to reject the request; if the Negotiation type value is 2, deciding whether to accept the Sensing establishment request according to the Sensing parameters, if so, allocating a new broadcast Sensing process identification, and setting a parameter status code value to accepted, if not, setting the parameter status code value to returned.
In some embodiments, if the access point accepts the request of the terminal, that is, if the result of the response is acceptance, the access point further stores the address or the identifier of the terminal in the information corresponding to the broadcast aware process identifier requested to be added by the terminal or the assigned new broadcast aware process identifier, and the terminal is called a member of the aware process corresponding to the broadcast aware process identifier. When the access point sends a perception data packet notification message to the terminal, the perception data packet notification message contains the address or the identification of the member corresponding to the broadcast perception process identification in the perception establishment response message; after the sensing data packet notification message is sent, the sensing data packet is sent after the predefined system time is waited, such as SIFS (short interframe space).

Specifically, after receiving the perception establishment response message, the terminal reads the broadcast message according to the time given by the Next TBTT parameter; and reading the sensing process parameters corresponding to the Broadcast message according to the Broadcast sending ID. Then the terminal receives a Sensing data packet according to the time, channel and bandwidth indicated by the Next Sensing TX time, the Sensing TX bandwidth or/and the Sensing TX channel in the read Sensing process parameters, and obtains wireless channel information according to the received Sensing data packet measurement; and denoising, feature extraction and classification comparison are carried out according to the measured wireless channel information to obtain a sensing result.

In some embodiments, if the terminal itself does not need to execute the sensing process any more, the terminal sends a sensing disconnection request message (e.g., a sensing teardown request message) to the access point, where the sensing disconnection request message includes a broadcast sensing process identifier that the terminal requests to quit. Illustratively, the sense disconnect request message settings are shown in table 5.
TABLE 5
And after receiving the perception disconnection request message, the access point sends a perception disconnection response message to the terminal, wherein the perception disconnection response message comprises a response result and a broadcast perception process identifier. Illustratively, the sense-to-disconnect response message settings are shown in table 6.

In some embodiments, the first message may be a connection request message or a probe request message. Illustratively, the first message settings are shown in table 7.
TABLE 7
And S203, after receiving the first message, the access point sends a second message to the terminal, wherein the second message indicates whether the access point supports the broadcast mode sensing process. In some embodiments, the second message may be a connection response message or a probe response message. Exemplarily, the second message settings are as shown in table 8.
TABLE 8
And S204, the terminal sends a perception establishing request message to the access point, wherein the perception establishing request message indicates that the terminal requests to join the broadcast perception process.
In this embodiment, after the terminal acquires the capability information of whether the ap supports the Broadcast Sensing process, only when both sides support the Broadcast Sensing process, if the Broadcast Sensing capability value of the terminal is 1 and the Broadcast Sensing capability value of the ap is 1, the steps S204 to S207 are executed.
