Description

Technical Field

[0001] The present application relates to the field of network communication technology, for example, to a collaborative group interaction method, a network device and a storage medium. Background Art

[0002] The frame protection between access points (APs) is an important means to improve the stability of the entire system. The frame protection between APs includes unicast frame protection and multicast frame protection between APs. Unicast frame protection requires APs to negotiate unicast keys in pairs. The scope of multicast frame protection is an AP cooperation group, that is, the APs in the cooperation group share a set of multicast keys to encrypt and decrypt the transmitted multicast information. Each AP cooperation group requires a master AP (Master AP) to maintain and distribute multicast keys. However, the frame protection mechanism within the cooperation group is not yet perfect. For example, when the master AP exits the cooperation group for some reason, such as restarting due to abnormal operation, unexpected power failure, etc., it is impossible to notify other members and dissolve the cooperation group; if the AP newly joined the cooperation group is far away from the master AP, it cannot communicate directly; if two adjacent APs join different cooperation groups, they cannot directly identify the cooperation group information of the multicast frame, nor can they distinguish the key information related to the cooperation group used in each multicast frame. The reliability of AP cooperation needs to be improved. Summary of the invention

[0025] The present application is described below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily. It should also be noted that, for ease of description, only the parts related to the present application rather than all structures are shown in the accompanying drawings.

[0026] Figure 1 FIG. 1 is a flowchart of a collaborative group interaction method provided by an embodiment, and the method can be applied to a first network device. Figure 1 As shown, the method provided in this embodiment includes the following steps:

[0027] In step 110, interaction is performed with a second network device to form a cooperation group.

[0028] In step 120, when the first network device is a master network device, cooperation group information is generated, where the cooperation group information includes multicast key information and group identifier information.

[0029] In step 130, the cooperation group information is sent to the second network device.

[0030] In this embodiment, the network device may be an access point (AP), a site, a multi-link access point or a multi-link site, etc. The first network device may interact with the surrounding second network devices, such as mutual authentication and negotiation, so as to create a collaboration group, and may determine the master network device and the slave network device. If the first network device is the master network device, the collaboration group information is generated and sent to other network devices in the collaboration group. The collaboration group information includes multicast key information and group identifier information. The group identifier information may be used as a basis for interaction between network devices in the collaboration group. For example, when a network device joins or exits the collaboration group, other network devices in the collaboration group may be notified and changes in collaboration group members may be clarified; when a network device joins different collaboration groups, the collaboration group information and key information of the multicast frame may be distinguished, so as to provide a reliable guarantee for the security of frame interaction between network devices.

[0031] In one embodiment, the method further includes: receiving the cooperation group information sent by the master network device when the first network device is a slave network device. In this embodiment, if the first network device is a slave network device and the second network device is a master network device, the first network device can receive the cooperation group information generated and sent by the second network device.

[0032] In one embodiment, it further includes: sending a first type frame to the target network device, wherein the first type frame includes the group identifier information. In this embodiment, the master network device or the slave network device in the collaboration group can send the first type frame to the target network device, and the target network device can be a network device outside the collaboration group, so that the target network device can discover the collaboration group.

[0033] In one embodiment, the first type of frame includes at least one of the following: a beacon frame, a probe response frame, and an action frame.

[0034] In one embodiment, when the first network device joins multiple cooperation groups, the first type frame includes group identifier information corresponding to the multiple cooperation groups.

[0035] Figure 2 A schematic diagram of a process for creating a collaboration group is provided in an embodiment. Figure 2 As shown, the first network device (AP1) and the second network device (AP2) form a collaboration group through a certain authentication negotiation method or other frame interaction method. AP1 negotiates to become the master AP, generates the first collaboration group information (Group 1, G1), and sends the G1 information to AP2 (the G1 information at least includes the multicast key information (Group key, GK) GK1 for encryption and decryption and the G1 identifier information). AP1 and AP2 include the G1 identifier information in the sent unicast or multicast frames (first type frames) to facilitate other network devices to discover the collaboration group.

[0036] In one embodiment, the collaboration group information further includes at least one of the following: group key expiration time information, member master / slave role information (master / slave indication) information.

[0037] In one embodiment, when the cooperation group information does not include the group key expiration time information, the group key is valid during the existence of the cooperation group. In this embodiment, if the cooperation group information does not set the group key expiration time information, it is considered that the cooperation group always exists and its key information is permanently valid.

[0038] In one embodiment, part of the cooperation group information is included in a physical frame header field or a medium access control (MAC) header field of the cooperation frame.

[0039] In one embodiment, the method also includes: when the first network device is a master network device, encrypting the second type frame according to the multicast key information; sending the encrypted second type frame to the slave network device in the collaborative group, the encrypted second type frame carrying the group identifier information, and the encrypted second type frame is used for the slave network device to determine whether to respond to the collaborative operation.

[0040] In one embodiment, the second type frame includes at least one of the following: a trigger frame between network devices, a Null Data Packet Advertisement (NDPA) frame, or a measurement frame.

[0041] In one embodiment, not responding to the cooperative operation includes at least one of the following: discarding the cooperative frame corresponding to the second type frame; entering a sleep mode within a set time period according to time information of the cooperative frame.

[0042] In one embodiment, responding to the collaborative operation includes: receiving a collaborative frame corresponding to the second type of frame; decrypting the collaborative frame according to the group key information corresponding to the collaborative frame; transmitting data on the corresponding channel resources indicated in the collaborative frame; wherein the channel resources include at least one of time division channel resources, frequency division channel resources and space division channel resources.

[0043] Figure 3 The following is a flow chart of a collaborative operation between network devices provided by an embodiment. Figure 3 As shown, after the first network device AP1 obtains the channel resources or needs to perform the channel measurement operation, it sends the second type frame to other members of the G1 group. AP1 encrypts the second type frame using the GK1 corresponding to the G1 group and sends it out with the G1 identifier information; the receiver matches the corresponding multicast information GK1 according to the G1 identifier information. If the match is successful, the receiver performs a coordinated response operation in response. If the match is unsuccessful, the receiver does not respond to the coordinated operation.

[0044] In one embodiment, when the first network device joins multiple collaboration groups, the second type frame includes a specific group identifier information.

[0045] In one embodiment, the method also includes: when the first network device is a master network device, before the multicast key information expires, sending new multicast key information and / or new group identifier information to the slave network devices in the collaboration group via an encrypted broadcast frame or unicast frame, and setting a new expiration time. Figure 4 A schematic diagram of a process for updating collaboration group information provided by an embodiment. Figure 4As shown, before the multicast key expires, the master AP sends a new multicast key and / or group identifier information to the slave APs in the group through an encrypted broadcast or unicast frame, and sets a new expiration time. The slave AP receives the new multicast key and / or group identifier information and updates the key information stored locally; after the group identifier information is updated, the first type of frame sent by the master AP and the slave AP includes the new group identifier information.

[0046] In one embodiment, the method further includes: when the first network device is a main network device, sending an indication frame to a neighboring network device, the indication frame including the group identifier information, the indication frame being used to instruct the first network device to exit the collaboration group; and locally deleting the collaboration group information.

[0047] In one embodiment, the indication frame is further used to instruct the neighbor network device to exit the cooperation group and delete local cooperation group information.

[0048] Figure 5 A schematic diagram of a process for a master network device to exit a collaboration group is provided in an embodiment. Figure 6 A schematic diagram of a process of exiting a collaboration group from a network device is provided in an embodiment. Figure 5 and Figure 6 As shown, when the first network device AP1 exits from G1 for some reason, the frame sent by AP1 to the neighbor AP carries the G1 identifier and indicates the operation information of exiting G1; AP1 locally deletes the group information corresponding to G1, and after exiting the G1 collaboration group, the subsequent frames sent to the neighbor AP no longer carry the G1 identifier. When AP1 is the master AP, the neighbor AP of the same G1 group also exits the G1 group, locally deletes the group information corresponding to G1, and the subsequent first-type frames do not contain the G1 identifier information; when AP1 is the slave AP, the master AP of the same G1 group will not exit the G1 group, nor will it locally delete the group information corresponding to G1, and the subsequent first-type frames will still contain the G1 identifier information.

[0049] In one embodiment, the method further includes: when the first network device is a slave network device and receives information about a neighboring network device joining or leaving the collaboration group through a unicast frame, sending group member change information to the master network device of the collaboration group through a unicast frame. In this embodiment, after receiving information about a neighboring slave AP joining or leaving the group through a unicast frame, the slave AP sends a unicast frame to the master AP of the group to inform it of group member changes.

[0050] In one embodiment, the method further includes: when the first network device is a slave network device and receives new multicast key information and / or new group identifier information, updating local multicast key information and group identifier information.

[0051] The embodiment of the present application provides a method for a multi-AP cooperative group, which implements the operation process of creating, deleting, updating, and adding a cooperative group, as well as a method for indicating cooperative group information in different application scenarios. An AP can discover one or more AP groups by receiving frames sent by neighboring APs; when an AP joins a multi-AP cooperative group, the AP carries the corresponding group identifier information of the group in the sent frame; each AP may join multiple cooperative groups at the same time and carry all group identifiers; the AP can send a frame carrying a specific group identifier to identify a request to join one or more specific cooperative groups; when an AP sends a cooperative frame, it carries a group identifier information to indicate the corresponding cooperative group; when an AP exits from one or more cooperative groups, it sends a frame to the surrounding APs to inform them of the exit from the cooperative group information.
