Description

Collaborative group interaction method, network device and storage medium Technical Field

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

[0002] Frame protection between access points (APs) is a key measure for improving overall system stability. Inter-AP frame protection includes unicast and multicast frame protection. Unicast frame protection requires APs to negotiate a unicast key between each other. Multicast frame protection is scoped to an AP collaboration group. APs within the collaboration group share a set of multicast keys to encrypt and decrypt transmitted multicast information. Each AP collaboration group requires a master AP to maintain and distribute the multicast keys. However, the current frame protection mechanism within a collaboration group is incomplete. For example, if a master AP leaves the collaboration group due to a malfunction, such as a reboot or unexpected power outage, it cannot notify other members and disband the collaboration group. Newly joined APs cannot communicate directly with the master AP if they are far away. If two adjacent APs join different collaboration groups, they cannot directly identify the collaboration group information in multicast frames or distinguish the collaboration group-specific key information used in each multicast frame. The reliability of AP collaboration needs to be improved.

[0026] The present application is described below in conjunction with the accompanying drawings and embodiments. It will be understood that the specific embodiments described herein are merely intended to explain the present application and are not intended to limit the present application. It should be noted that, unless there is a conflict, the embodiments and features within the embodiments of the present application may be combined with each other in any manner. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present application, not all structures.

[0027] Figure 1 is a flow chart of a collaborative group interaction method provided by an embodiment, which can be applied to a first network device. As shown in Figure 1, the method provided by this embodiment includes the following steps:

[0028] In step 110, interaction is performed with a second network device to form a cooperation group.

[0029] 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.

[0030] In step 130, the cooperation group information is sent to the second network device.

[0031] 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, 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 can 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 can be notified and changes in collaboration group members can be clarified. When a network device joins different collaboration groups, the collaboration group information and key information of the multicast frame can be distinguished, providing a reliable guarantee for the security of frame interaction between network devices.

[0032] In one embodiment, the method further includes: receiving, when the first network device is a slave network device, the collaboration group information sent by the master 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 may receive the collaboration group information generated and sent by the second network device.

[0033] In one embodiment, the method further includes: sending a first type frame to a target network device, wherein the first type frame includes the group identifier information. In this embodiment, either a master network device or a slave network device in the collaborative group can send the first type frame to the target network device, and the target network device can be a network device outside the collaborative group, so that the target network device can discover the collaborative group.

[0034] 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.

[0035] 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.

[0036] FIG2 is a schematic diagram of a process for creating a collaborative group provided by an embodiment. As shown in FIG2 , a first network device (AP1) and a second network device (AP2) form a collaborative group through a certain authentication negotiation method or other frame interaction method. AP1 negotiates to become the master AP, generates the first collaborative group information (Group 1, G1), and sends the G1 information to AP2 (the G1 information should at least include 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 unicast or multicast frames (first type frames) they send to facilitate other network devices to discover the collaborative group.

[0037] In one embodiment, the collaboration group information further includes at least one of the following: multicast key expiration time information, member master / slave role information (master / slave indication) information.

[0038] In one embodiment, if the cooperation group information does not include multicast key expiration information, the multicast key is valid while the cooperation group exists. In this embodiment, if the cooperation group information does not include multicast key expiration information, it is considered that the cooperation group exists and its key information is permanently valid.

[0039] 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.

[0040] In one embodiment, the method further 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 being used for the slave network device to determine whether to respond to the collaborative operation.

[0041] In one embodiment, the second type of frame includes at least one of the following: a trigger frame between network devices, a Null Data Packet Announcement (NDPA) frame, or a measurement frame.

[0042] 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.

[0043] 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 multicast 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.

[0044] Figure 3 is a schematic diagram of a collaborative operation between network devices, provided by one embodiment. As shown in Figure 3, after obtaining channel resources or needing to perform channel measurement, the first network device, AP1, sends a second-type frame to other members of group G1. AP1 encrypts the second-type frame using GK1, the corresponding G1 group member, and sends it with the G1 identifier. The receiver matches the G1 identifier to the corresponding multicast message, GK1. If the match is successful, the receiver performs a collaborative response. If the match is unsuccessful, the receiver does not respond to the collaborative operation.

[0045] In one embodiment, when the first network device joins multiple collaboration groups, the second type frame includes specific group identifier information.

[0046] In one embodiment, the method further includes: in the case where the first network device is the 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 through an encrypted broadcast frame or unicast frame, and setting a new expiration time. Figure 4 is a flow chart of updating collaboration group information provided by one embodiment. As shown in Figure 4, before the multicast key expires, the master AP sends the 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 locally stored key information; after the group identifier information is updated, the first type of frame sent by the master AP and the slave AP contains the new group identifier information.

[0047] In one embodiment, the method further includes: when the first network device is a primary 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 collaborative group; and locally deleting the collaborative group information.

[0048] 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.

[0049] Figure 5 is a flowchart of a master network device exiting a collaborative group provided by an embodiment. Figure 6 is a flowchart of a network device exiting a collaborative group provided by an embodiment. As shown in Figures 5 and 6, when the first network device AP1 exits from G1 for some reason, the frame sent by AP1 to the neighboring 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 collaborative group, it no longer carries the G1 identifier in the subsequent frames sent to the neighboring APs. When AP1 is the master AP, the neighboring APs of the same G1 group also exit the G1 group, locally delete the group information corresponding to G1, and the subsequent first-type frames do not contain the identifier information of G1; 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 identifier information of G1.

[0050] 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 collaborative group via a unicast frame, sending group membership change information to the master network device of the collaborative group via a unicast frame. In this embodiment, after receiving information about a neighboring slave AP joining or leaving the group via a unicast frame, the slave AP sends a unicast frame to the master AP of the group to notify it of the group membership change.

[0051] 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.

[0052] The embodiments of the present application provide a method for a multi-AP cooperative group, which implements the operational procedures for creating, deleting, updating, and adding cooperative groups, 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 frames it sends; each AP may join multiple cooperative groups at the same time and carry all group identifiers; an AP can send a frame carrying a specific group identifier to indicate 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 inform surrounding APs of the information of exiting the cooperative group.

[0054] In step 210, an information frame from a neighboring network device is received.

[0055] In step 220, a cooperation group is determined according to the information frame.

[0056] In step 230, an authentication frame is sent to the network device in the collaboration group, wherein the authentication frame includes group identifier information of the collaboration group, and the authentication frame is used to request to join the collaboration group.

[0057] In this embodiment, the third network device can send an authentication frame carrying the group identifier to any nearby network device in the collaborative group. The network device receiving the authentication frame can be either the master or slave network device in the collaborative group. Requesting to join the collaborative group through the authentication frame provides a basis and reliable guarantee for secure frame exchange between network devices.

[0058] Figure 8 is a schematic diagram of a process for joining a collaborative group, provided by an embodiment. As shown in Figure 8, a third network device (AP3) discovers a collaborative group G1 by receiving a first or second type frame from a neighboring network device (AP1). During authentication and negotiation with AP1, AP3 carries the G1 identifier, indicating a request to join the collaborative group. Depending on the authentication and negotiation results, the following options are possible: 1) If the authentication and negotiation succeed, AP1 sends G1 information (including GK1 information) to AP3 during the negotiation; 2) If the authentication and negotiation fails, AP1 does not send G1 information to AP3. After becoming a member of G1, AP3 carries G1's group identifier information in the corresponding first type frame.
