Description

Wireless local area network communication method, related equipment and system

Technical field

The present invention relates to the field of communications, and in particular, to a wireless local area network communication method, related device and system.

Background technique

The IEEE 802.11 Working Group established the High Efficiency WLAN Study Group (HEW SG) in 2013 and established the 802.11ax Working Group (TGax) in 2014 to prepare for the introduction of Orthogonal Frequency Division Multiple Access (Orthogonal Frequency Division Multiple). Access, OFDMA), scheduling and other new technologies. Collaboration between APs is particularly important for access points (APs) that use the 802.11ax standard protocol because they operate in unlicensed bands.

Referring to FIG. 1, FIG. 1 is a schematic diagram of a scenario of a Collaborative Service Set (CSS) in the prior art. The CSS is composed of a plurality of basic service sets (BSSs). Since the BSSs can pre-negotiate the internal interaction mode of each BSS, the APs in each BSS interact with the user equipments (Stations, STAs). The data is not interfered by other BSSs, and the negotiation between the BSSs may be specifically performed by the AP interaction data in each BSS.

Please refer to FIG. 1A. FIG. 1A is a schematic diagram of the communication principle of APs according to existing standards. In FIG. 1A, AP1 is the master AP, and AP2, AP3, AP4, and AP5 are slave APs. The process of the AP and the slave AP interacting with each other is: AP1 contends the channel, and sends a status request message to AP2 after the channel is successfully contending ( Coordination Information request), after receiving the status request message, the AP2 sends a status message to the AP1. After receiving the status message fed back by the AP2 according to the status request message, the AP1 contends for the channel again to send a status request message to the AP3. And so on to obtain all status messages of the slave AP, and finally generate a coordination information (Coordination Information commend) of the cooperation service set in combination with all the received status messages, and send the cooperation message to each slave AP, so that the cooperation service concentrates Each AP interacts with the respective STAs in the manner indicated by the cooperation message.

In a dense deployment scenario, the APs are densely distributed, and the master APs in the collaboration service are centralized. Channel competition is required before the information exchange from the AP, and repeated channel competition greatly increases the time overhead, so that the efficiency of data exchange between APs is low.

detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. In addition, the fields in the frame structure listed in the embodiment of the present invention are only partial fields, and other fields may be included in the actual application.

Referring to FIG. 2, FIG. 2 is a schematic diagram of the principle of communication between APs according to an embodiment of the present invention. Figure 2 includes AP1, AP2, AP3, AP4, and AP5, where AP1 is the master AP and AP2~AP5 are the slave APs. Compared with the prior art shown in FIG. 1A, the AP1 in FIG. 2 only needs to successfully compete for the channel once, and can send a Coordination Information request to the AP2 to the AP5, and then receive the AP2 to AP5 simultaneously (or synchronously). The Coordination Information response is sent to the AP2 to AP5 simultaneously (or synchronously) according to the Coordination Information Co., which improves the efficiency of data exchange between the APs.

Referring to FIG. 3, FIG. 3 is a schematic flowchart of a wireless local area network communication method according to an embodiment of the present invention, which is described from one end of a first access point, and the specific steps are as follows.

Step S301: The first access point sends a status request message to the multiple second access points, where the status request message is used to specify channel resources for each second access point, and indicates that multiple second access points feed back status information. Wherein the first access point and the plurality of second access points belong to a collaborative service set.

Specifically, the first access point and the second access point are both access points in the collaborative service set, where An access point may be a master AP; a second access point may be a slave AP, and the number is multiple, and is used to participate in the interaction led by the master AP.

Before the first access point sends the status request message to the multiple second access points, it first needs to listen to the channel. If the channel A is detected to be idle, then the first access point accesses multiple second accesses through channel A. The point sends a status request message, and the specific manner of sending may be broadcast.

After receiving the status request message, each second access point may determine that the received status request message is used to indicate feedback status information, including but not limited to channel status information of the BSS where the second access point is located ( Channel State Information (CSI), Clear Channel Assessment (CCA), number of associated STAs, number of active STAs, and load information.

Further, the status request message also indicates how to allocate channel resources such that each second access point has a respective channel resource on channel A. The allocation of channel resources may be specifically performed by orthogonal frequency division multiple access (OFDMA) technology, frequency division multiple access (FDMA) technology, and time division multiple access (TDMA) technology. It is implemented by any one or more of the Space Division Multiple Access (SDMA) technology and the Code Division Multiple Access (CDMA) technology. Of course, there are other implementation modes. One by one example.

Step S302: The first access point receives a status message including respective status information that each second access point transmits by assigning to a respective channel resource.

Specifically, each of the second access points simultaneously (or synchronously) feeds back the respective status message to the first access point through the corresponding channel resource without interfering with each other, and accordingly, the first access point receives each second access. A status message sent by the point.

Step S303: The first access point combines the status message to generate a cooperation message corresponding to each second access point for the coordinated service set.

Specifically, the first access point performs comprehensive analysis on the received status request message of each second access point simultaneously (or synchronously) to generate a cooperation message of the collaboration service set, where each second access point And the first access point corresponds to a respective collaboration message.

Step S304: The first access point sends a corresponding cooperation message to each second access point by using a channel resource corresponding to each second access point.

Specifically, the first access point sends the corresponding cooperation message to each second access point simultaneously (or synchronously) through the channel resources corresponding to the second access point. After receiving the cooperation message, each of the second access points performs data interaction with the respective STAs according to the cooperation message, so that each access point does not interfere with each other when interacting with the respective STAs.

It should be noted that the steps S301-S304 may be repeatedly performed according to a preset time interval, that is, the channel resources in the collaborative service set may be dynamically adjusted according to the change of the state information of each access point, so as to improve the utilization of channel resources. The efficiency of the interaction between the rate and the AP.

Further, the wireless local area network communication method shown in FIG. 3 also has the following optional embodiments.

For step S301, the first access point in the coordinated service set sends a status request message to the plurality of second access points, where the status request message includes channel resource allocation information and an identity of the cooperative service set; channel resource allocation information is used for each The second access point specifies a channel resource, and the identity identifier is used by the plurality of second access points to determine whether they belong to the coordinated service set, and when the determination result is yes, the status information is fed back to the first access point.

Specifically, there may be multiple collaboration service sets in a certain spatial range, each collaboration service set corresponding to its own identity, and the access points in each collaboration service set pre-stored the identity of the associated collaboration service set. . Correspondingly, the status request message must carry an identity identifier, so that the second access point can analyze that the status request message is from the collaboration service set to which it belongs.

The channel resource allocation information and the identity identifier included in the status request message may be indicated in the frame format of the Medium Access Control (MAC) layer at the same time; or the channel resource allocation information is indicated in the frame format of the MAC layer, and the identity is in the physical The common part indication of HE-SIG-A or HE-SIG-B of the physical layer (PHY); Table 3-1 shows that the channel resource allocation information and the identity identifier are both indicated in the frame format of the MAC layer, and the MAC layer The frame format is shown in Table 3-2. The channel resource allocation information is indicated in the frame format of the MAC layer. When the identity is indicated by the PHY layer, the frame format of the MAC layer.

Table 3-1

Table 3-2

In Table 3-1 or 3-2, the "CSS color" field indicates the identity of the collaborative service set, and the "Resource Indication (MAP)" field defines that the second access point reports the collaboration to the first access point. The resource indication of the information includes channel resource allocation information (eg, a mapping relationship between a MAC address of each second access point and a channel resource); and a “Duration” field defines that the receiving node does not send out within the indicated time period. Data; the "Frame control" field defines how the Resource Indication field is used and how the identity is indicated. For Table 3-1, the "Frame Control" field defines the identity identified in the "Identification" field of the frame, and for Table 3-2, the "Frame Control" defines the identity identified at the PHY layer.

For the step S302, after the second access point receives the status request message that is sent by the first access point and includes the foregoing identity, the status message is sent to the first access point, and the status message may include the identity identifier. After receiving the status message, the first access point discriminates whether the status message is from the collaborative service set to which it belongs, and if so, reads the data in the status request message, and if not, does not process. The identity identifier in the status message may be indicated in the PHY layer or in the frame format of the MAC; Table 3-3 is the frame format of the MAC layer when the identity identifier is indicated by the PHY layer; Table 3-4 is the identity identifier. The frame format of the MAC layer when indicated in the frame format of the MAC layer.

Table 3-3

Table 3-4

The “identity” field is the identity of the collaboration service set, and the “frame control” field defines the indication of the identity. For Table 3-3, the "Frame Control" field defines the identity in the "Identification" field of the frame. For Table 3-4, the "Frame Control" field defines the identity in the PHY layer indication.

For step S304, the collaboration message includes an identity of the collaboration service set, and the identity identifier may be indicated at the PHY layer or may be indicated in a frame format of the MAC layer.

In yet another alternative, the frame format containing the "identity" field is compared to the existing standard base. The frame format of the service set is compatible, specifically, adding N bits in the basic service set identifier field (BSS color) of the existing standard, and indicating the existing basic service set when the added N bits are equal to the preset value. The identification field and the added N bits are used to indicate an "CSS color" field, and when the added N bits are equal to another preset value, the existing basic service set identification field and the added N are indicated. The bit is used to indicate the basic service set identifier. For example, if the existing basic service set identifier field occupies 6 bits, the embodiment of the present invention adds 1 bit to the existing 6 bits, as shown in Table 3-5, and the preset is added.

In Table 4-4, "Frame Control" defines the above frame for requesting the establishment of a collaborative service set.

Further, the foregoing setup message may further carry an identity of the collaboration service set to be established, so that the neighboring access point that receives the setup message learns that the collaboration service set to be established is a collaborative service set. The identity may be indicated by the first access point in the public part of HE-SIG-A or HE-SIG-B in the frame of the PHY layer, or may be indicated by the first access point in the frame format of the MAC layer. When indicated in the frame format of the PHY layer, the frame format of the MAC layer is as shown in Table 4-5; when indicated in the frame format of the MAC layer, the frame format of the MAC layer is as shown in Table 4-6.

Table 4-5

Table 4-6

Step S402: The first access point receives a response message that the neighboring access point feeds back according to the setup message.

Specifically, after the neighboring access point that receives the setup message parses the setup message, it can analyze, according to the “frame control” field, that a response request message (Coordination request) needs to be sent to the first access point, and therefore, the setup message is received. The neighboring access point generates a response message, and sends the response message to the first access point. When the response message is sent, the frame format of the MAC layer is as shown in Table 4-7.

Table 4-7

In Tables 4-7, the "Frame Control" field defines a response message for establishing a collaborative service set; the "Received Signal Strength Indication (RSSI)" field defines the signal strength measured to the setup message, in the present invention. In the embodiment, the RSSI is an optional field.

Step S403: The first access point establishes, according to the received response message, a collaboration service set including a first access point and multiple second access points, where the second access point is a neighbor that sends a response message. Access Point.

Specifically, although the first access point sends a setup message to each neighboring access point, some neighboring access points may not be within the signal coverage of the first access point, and may not receive the setup message; Although the neighboring access points are within the signal coverage of the first access point, the first access point is not within the signal range of the neighboring access points, and therefore, the first access point does not receive the access. The response message sent by the point; there are also some neighboring access point protocol-based rules that do not respond to the setup message, so the first access point also does not receive the response message of the neighboring access points. Of course, there may be other reasons that cause the first access point to receive a response message from a portion of the neighboring access points.

Further, the first access point analyzes all the received response messages to obtain all the neighboring access points that sent the response message, and establishes the neighboring access points and the first access point. Collaborate the service set and generate the identity of the collaboration service set at the same time. For convenience of description, the neighboring access points analyzed by the first access point may be classified as the second access point. That is to say, when the first access point determines the members of the cooperative service set, the requirement for the neighboring access point is that a response message is sent, and the response message can be received by the first access point.

In an optional solution, when the first access point determines the member of the cooperative service set, the requirement for the neighboring access point is: a response message is sent, and the response message can be received by the first access point. In addition, the RSSI when interacting with the first access point must reach a preset value. RSSI includes two aspects, adjacent access The RSSI of the receiving setup message and the RSSI of the first access point receiving the response message, wherein the RSSI of the neighboring access point receiving the setup message is measured by the neighboring access point, and sent to the first access point by using the response message. The RSSI of the first access point receiving the response message is measured by the first access point. The RSSI of the foregoing interaction with the first access point must reach a preset value, that is, the RSSI of the neighboring access point receiving the setup message and the RSSI of the first access point receiving the response message need to reach a preset value. Or one of them needs to reach the preset value.

Further, after the first access point establishes the collaborative service set, when the collaborative service set does not have a corresponding identity, the identity of the collaborative service set may also be generated for distinguishing from other collaborative service sets. In an optional solution, the basic service set identifier of the basic service set where the first access point is located may be determined as the identity identifier; in yet another optional solution, the identity identifier is the first access point according to the pre-preparation A value randomly generated by the algorithm; in another optional solution, when the first access point sends the establishment message of the neighboring access point to include the identity identifier, the included identity identifier can be used as the identity of the collaboration service set. Logo.

Step S404: The first access point sends an acknowledgement message to the multiple second access points, where the acknowledgement message includes an identity identifier corresponding to the established collaboration service set, and is used to indicate that the second access point belongs to the collaboration service set corresponding to the identity identifier. .

Specifically, when transmitting the acknowledgement message, the identity identifier may be indicated by the first access point in the common part of the HE-SIG-A or HE-SIG-B of the PHY layer, and when indicated by the PHY layer, the frame format of the MAC layer As shown in Table 4-10. The "APn Address" field is used to indicate the MAC address of each of the second access points that are finally joined to the collaborative service set.

The identity identifier may also be indicated by the first access point in the frame format of the MAC layer. When indicated in the frame format of the MAC layer, the frame format of the MAC layer is as shown in Table 4-11, where the "identity" field is The identity used to indicate the set of collaboration services that have been established. The "APn Address" field is used to indicate the MAC address of each of the second access points that are finally joined to the collaborative service set.

Table 4-11

In an optional solution, the foregoing “APn address” field may further indicate the number information (APn ID) of the second access point. In the existing standard, the number information of the access point occupies the bit position. Less than the bit occupied by the MAC address can improve the efficiency of cooperation between the access points of the cooperative service.

In an optional solution, after the collaboration service set is established, the first access point and the multiple second access points send the identity information of the collaboration service set to the respective STAs, so that the STAs are only followed by the collaboration service. The set of data is processed. Specifically, the first access point sends the acknowledgement message to the STAs associated with itself when sending the acknowledgement message to each second access point; and may also send the cooperation message to each second access point. The cooperation message is sent to the STAs associated with itself; a message for notifying the establishment of the collaboration service set, etc., may also be separately sent to the STAs of the first access point. Further, after confirming that the second access point belongs to the collaborative service set, the second access point may also send to its own STAs to notify the STAs to belong to the established collaborative service set.

Step S405: The first access point sends a status request message to the plurality of second access points, where the status request message is used to specify channel resources for each second access point, and instructs the multiple second access points to feed back status information. Wherein the first access point and the plurality of second access points belong to a collaborative service set.

Step S406: The first access point receives a status message including respective status information that each second access point transmits by assigning to a respective channel resource.

Step S407: The first access point combines the status message to generate a cooperation message corresponding to each second access point for the cooperation service set.

Step S408: The first access point sends a corresponding cooperation message to each second access point by using a channel resource corresponding to each second access point.

Specifically, steps S405-408 can be respectively referred to refer to steps S301-S304, and details are not described herein again.

Regardless of the second access The number of the points is that the first access point needs to obtain the state information of each second access point only once, and the efficiency of the data exchange between the first access point and each second access point is improved.

Before the first access point and the second access point in the collaboration service set perform data interaction, the first access point first establishes a collaboration service set, and generates an identity identifier of the collaboration service set, and carries the interaction between the access points. Identity information makes the interaction more orderly and accurate.

It should be noted that the difference between the beacon frame and the preset time frame is that the beacon frame is a standard broadcast frame, and each second access point is in an idle state when broadcasting the beacon frame, that is, each second access point. Both can receive the beacon frame, so they can all be parsed to the preset time; and the preset time frame is the newly established broadcast frame, and each second access point does not know the time for broadcasting the preset time frame, that is, in the broadcast pre- When the time frame is set, each second access point is not necessarily in an idle state. Therefore, some second access points may not be resolved to the preset time.

Further, the foregoing broadcast message may also be a status request message sent by the first access point. It should be noted that the first access point periodically sends a status request message, and each status request message includes a preset time (TX time for next CI request) to indicate the time when the status request message is sent next time. The request frame of the physical layer corresponding to the status request message is shown in Table 5-2.

Further, the preset time indicated in the broadcast message may be one time or multiple times. When it is a time, the one time is used to indicate the time of sending the status request message for the next time. Each time corresponds to the time when a status request message is sent.

Referring to FIG. 5A, FIG. 5A is a schematic diagram showing the principle of indicating a preset time by a beacon frame. In FIG. 5A, after receiving the beacon frame, the AP2 to the AP5 are idle at the time indicated by the preset time to receive the status request message; after receiving the beacon frame next time, the AP2 to the AP5 receive the status request message according to the indicated time again. , so loop.

Referring to FIG. 5B, FIG. 5B is a schematic diagram showing the principle of indicating a preset time by a beacon frame and a status request message. In FIG. 5B, after AP2 to AP5 receive the beacon frame, the time represented by the "preset time" field in the beacon frame is idle to receive the status request message, and further, the status request message indicates the next transmission status request. The preset time of the message, and so on, so there is no need to cyclically send beacon frames.

Referring to FIG. 5C, FIG. 5C is a schematic diagram showing the principle of indicating a preset time by using a preset time frame. For the method of using the preset time frame, reference may be made to the method of using the beacon frame in FIG. 5A and FIG. 5B, and details are not described herein again.

Further, in an optional solution, the foregoing broadcast message may further include an identity identifier, configured to clarify, to the device that receives the broadcast message, the broadcast message as a message in the collaborative service set, so that the devices select whether to broadcast the message. The data is processed.

Step S502: The first access point sends a status request message to the multiple second access points, where the status request message is used to specify channel resources for each second access point, and indicates that multiple second access points feed back status information. Wherein the first access point and the plurality of second access points belong to a collaborative service set.

Step S503: The first access point receives a status message containing the respective status information sent by each second access point by being assigned to the respective channel resource.

Step S504: The first access point combines the status message to generate a cooperation message corresponding to each second access point for the cooperation service set.

Step S505: The first access point sends a corresponding cooperation message to each second access point by using a channel resource corresponding to each second access point.

Specifically, the steps S502 to 505 can be respectively referred to refer to steps S301 to S304, and details are not described herein again.

It should be noted that steps S501-505 may be repeatedly performed according to preset time intervals.

Specifically, the first access point sends the acknowledgement message to the STAs associated with itself when sending the acknowledgement message to each second access point; The access point sends the cooperation message to the STAs associated with itself, and may also send a message for notifying the establishment of the collaboration service set to the STAs of the first access point. Further, after confirming that the second access point belongs to the collaborative service set, the second access point may also send a message to its own STAs to notify the STAs to belong to the established collaborative service set.

It should be noted that the acknowledgement message is a confirmation message generated by all the response messages after the first access point receives the response message fed back by all neighboring access points. Specifically, although the first access point sends a setup message to each neighboring access point, some neighboring access points may not be within the signal coverage of the first access point, and may not receive the setup message; Although the neighboring access points are within the signal coverage of the first access point, the first access point is not within the signal range of the neighboring access points, and therefore, the first access point does not receive the access. The response message sent by the point; there are also some neighboring access point protocol-based rules that do not respond to the setup message, so the first access point also does not receive the response message of the neighboring access points. Of course, there may be other reasons that cause the first access point to receive a response message from a portion of the neighboring access points.

Further, the first access point analyzes all the received response messages to obtain all the neighboring access points that sent the response message, and establishes the neighboring access points and the first access point. Collaborative service set. For convenience of description, the neighboring access points analyzed by the first access point may be classified as the second access point. That is to say, when the first access point determines the members of the cooperative service set, the requirement for the neighboring access point is that a response message is sent, and the response message can be received by the first access point.

In an optional solution, when the first access point determines the member of the cooperative service set, the requirement for the neighboring access point is: a response message is sent, and the response message can be received by the first access point. In addition, the RSSI when interacting with the first access point must reach a preset value. The RSSI includes two aspects, the neighboring access point receives the RSSI of the setup message and the RSSI of the first access point receives the response message, wherein the RSSI of the neighboring access point receiving the setup message is measured by the neighboring access point, and The response message is sent to the first access point; the RSSI of the first access point receiving the response message is measured by the first access point. The RSSI when the foregoing interaction with the first access point must reach a preset value means that the RSSI of the neighboring access point receiving the setup message and the RSSI of the first access point receiving the response message need to reach a preset value, or One of them needs to reach the preset value.

Further, after the first access point establishes the collaborative service set, when the collaborative service set does not have a corresponding identity, the identity of the collaborative service set may also be generated for distinguishing from other collaborative service sets.

In an optional solution, the basic service set identifier of the basic service set may be determined as an identity identifier. In another optional solution, the identity identifier is a value randomly generated by the first access point according to a preset algorithm. In still another optional solution, when the first access point sends the establishment message of the neighboring access point to include the identity identifier, the included identity identifier may be used as the identity of the collaboration service set.

Step S704: The second access point receives the status request message sent by the first access point, where the status request message is a status request message sent by the first access point to the multiple second access points, and the status request message is used for each The second access point specifies a channel resource and indicates a plurality of second access points to feed back state information, wherein the first access point and the second access point belong to a collaborative service set.

Step S705: The second access point simultaneously sends a status message including status information to the first access point by using the channel resource assigned to itself and the other access points of the plurality of second access points, so that the first access is performed. The point binding status message generates a collaboration message for each of the second access points for the collaborative service set.

Step S706: The second access point receives the cooperation message sent by the first access point, where the cooperation message is sent by the first access point to each second access point by using a channel resource corresponding to each second access point. Corresponding collaboration message.

Specifically, the steps S704-706 may correspond to the steps S601-S603, and details are not described herein again.

In the method embodiment shown in FIG. 7, after the channel is successfully contending, the first access point sends a status request message to each second access point, where the status request message includes information for indicating a channel resource block, Each of the second access points is allocated channel resources, and accordingly, each of the second access points simultaneously (or synchronously) transmits status information to the first access point through the channel resources allocated to itself. Regardless of the number of the second access points, the first access point only needs one channel competition to obtain the state information of each second access point, and improves the first access point and each second access point. The efficiency of interactive data.

Further, before the data access is performed between the first access point and the second access point in the collaboration service set, the first access point first establishes a collaboration service set, generates an identity identifier of the collaboration service set, and performs an access point between the access points. The identity information is carried in the interaction to make the interaction more orderly and accurate.

The preset time frame (CI-announce) is used to indicate the preset time. The frame format of the preset time frame is shown in Table 8-1.

Table 8-1

It should be noted that the difference between the beacon frame and the preset time frame is that the beacon frame is a standard broadcast frame, and each second access point is in an idle state when broadcasting the beacon frame, that is, each second access point. Both can receive the beacon frame, so they can all be parsed to the "preset time"; and the preset time frame is the newly established broadcast frame, and each second access point does not know the time to broadcast the preset time frame, that is, When the preset time frame is broadcast, each second access point is not necessarily in an idle state. Therefore, some second access points may not be able to resolve to the preset time.

Further, the foregoing broadcast message may also be a status request message sent by the first access point. It should be noted that the first access point periodically sends a status request message, and each status request message includes a preset time to indicate the time when the status request message is sent next time. The request frame of the physical layer corresponding to the status request message is shown in Table 8-2.

Table 8-2

Referring to FIG. 5A, FIG. 5A is a schematic diagram of indicating a preset time by a beacon frame broadcast frame. In FIG. 5A, after receiving the beacon frame, the AP2 to the AP5 are idle at the time indicated by the preset time to receive the status request message; after receiving the beacon frame next time, the AP2 to the AP5 receive the status according to the indicated time again. State request message, so loop.

Referring to FIG. 5B, FIG. 5B is a schematic diagram of indicating a preset time by a beacon frame and a status request message. In FIG. 5B, after AP2 to AP5 receive the beacon frame, the time represented by the "preset time" field in the beacon frame is idle to receive the status request message, and further, the status request message indicates the next transmission status request. The preset time of the message, and so on, so there is no need to cyclically send beacon frames.

Referring to FIG. 5C, FIG. 5C is a schematic diagram of indicating a preset time by using a preset time frame. For the method of using the preset time frame, reference may be made to the method of using the beacon frame in FIG. 5A and FIG. 5B, and details are not described herein again.

Step S803: The second access point simultaneously sends a status message including status information to the first access point by using the channel resource assigned to itself and the other access points of the plurality of second access points, so that the first access is performed. The point binding status message generates a collaboration message for each of the second access points for the collaborative service set.

Step S804: The second access point receives the cooperation message sent by the first access point, where the cooperation message is sent by the first access point to each second access point by using a channel resource corresponding to each second access point.

Regardless of the number of the second access points, the first access point only needs one channel competition to obtain the state information of each second access point, and improves the first access point and each second access point. The efficiency of interactive data.

The RSSI when the foregoing interaction with the first access point must reach a preset value means that the RSSI of the neighboring access point receiving the setup message and the RSSI of the first access point receiving the response message need to reach a preset value, or One of them needs to reach the preset value.

Further, after the first access point establishes the collaboration service set, if the collaboration service set does not have a corresponding identity identifier, the identity identifier of the collaboration service set may also be generated for distinguishing from other collaboration service sets.

In the method shown in FIG. 11, the first access point sends a setup request message to the second access point, and when the first access point can receive the response message fed back by the second access point according to the setup message, It may be determined that both the first access point and the second access point are within the signal coverage of the other party, thus establishing a collaborative service set including the first access point and the plurality of second access points, for simultaneously using multiple APs Interacting data improves the efficiency of interaction between APs in dense scenarios.

It should be noted that, after the cooperative service set is established according to the embodiment shown in FIG. 11, each AP in the cooperative service set can receive and transmit data by using a channel resource block assigned to itself, thereby reducing channel competition overhead before transmitting data.
