The link reconfiguration response message, i.e. the link reconfiguration response, is used for the network access device to feed back the reconfiguration response result of the target link to the terminal device. The link reset response message may include link reset result information. The link reconfiguration result information may be used to characterize a negotiation result of the network access device for reconfiguration of the target link.

In some embodiments, the link reset result information includes reset negotiation result information and target link information. The reset negotiation result information is used for indicating the result of the negotiation reconfiguration between the terminal equipment and the network access equipment. The target link information is used to indicate a target link.

In some examples, resetting the negotiation result information may include a negotiation acceptance identification and a negotiation rejection identification. The negotiation acceptance identifier characterizes that the network access equipment accepts the reconfiguration of the target link. The negotiation rejection identifier represents that the network access equipment rejects the reconfiguration of the target link.

In some examples, the link reset result information may further include one or more of a second service identifier, access point capability information, access point operation information, and second authentication and authorization information. And the second service identifier in the link resetting result information is used for identifying that the network access equipment accepts the service supported by the target link. For specific contents of the service, reference may be made to the above-mentioned related description, and details are not described herein again. And the access point capability information in the link resetting result information is used for representing the capability information set by the logic access point in the network access equipment. For example, the access point capability information may include, but is not limited to, a transmission rate of the logical access point, and the like. And the access point operation information in the link resetting result information is used for ensuring the operation information set by the logic access point in the network access equipment. For example, the access point operation information may include, but is not limited to, power saving mode parameters of the logical access point. The second authentication and authorization information can be used for generating a key for data security transmission in the target link.

For example, fig. 9 is a schematic diagram of an example of link reset result information provided in the embodiment of the present application. As shown in fig. 9, the link notification result information may include reset negotiation result information Status code, a logical terminal identification STA ID, a logical access point identification AP ID, a second traffic identification TID2, access point Capability information AP Capability info, access point operation information AP operation info, and second authentication information Auth-info 2.

The terminal device and the network access device may perform data transmission between the terminal device and the network access device according to the terminal capability information, the terminal operation information, the access point capability information, and the access point operation information in the above embodiments.

In step S204, the execution logic data transceiver terminal updates the link mapping relationship stored in the terminal device according to the link resetting result information.

The link mapping relationship comprises the mapping relationship between the logical data transceiver terminal and the logical access point in each link. The updated link mapping relationship of the terminal device comprises the mapping relationship between the logical data transceiver terminal and the logical access point in the link matched with the link resetting result information. Specifically, the link mapping relationship may include a logical terminal identifier of a logical data transceiver terminal and a logical access point identifier of a logical access point, where each link has a correspondence relationship. For specific contents of the logical terminal identifier and the logical access point identifier, reference may be made to the relevant description of the above embodiments, which is not described herein again.

In some examples, the link mapping relationship may further include a status identification of the logical data transceiving terminal and/or a master-slave identification of the logical data transceiving terminal. The state identifier of the logical data transceiving terminal is used for characterizing the state of the logical data transceiving terminal. For example, the status identification may include an active status identification or an inactive status identification. The active state identification indicates that the logic data transceiver terminal is connected with the logic access point and can perform data transceiving. The inactive state flag indicates that the logical data transceiver terminal is connected to the logical access point but cannot perform data transmission and reception. The active state identifier and the inactive state identifier may include, but are not limited to, numbers, letters, other characters, and the like. For example, the Active state identification may be Active and the inactive state identification may be De-Active. The master-slave identification of the logical data transceiving terminal comprises the master identification of the logical data transceiving terminal and the slave identification of the logical data transceiving terminal. The master logical data transceiving terminal in the terminal device has a master identity and the slave logical data transceiving terminal in the terminal device has a slave identity. The master and slave identifiers may include numbers, letters, other characters, etc., and are not limited thereto. For example, the master identity may be Primary and the Slave identity may be Slave. Note that the slave id may be empty.

In some examples, the link mapping relationship may be implemented as a multilink management information table. The multilink management information table records the logical terminal identification of the logical data transceiver terminal and the logical access point identification of the logical access point in each link. The multilink management information table can also record the state identification of the logic data transceiver terminal and/or the master-slave identification of the logic data transceiver terminal.

For example, fig. 10 is a schematic diagram of an example of a multilink management information table provided in an embodiment of the present application. As shown in fig. 10, the multilink information management table includes a logical terminal identification STA ID, a state identification Status1 of the logical data-transceiving terminal, and a logical access point identification AP ID.

In the embodiment of the present application, a link reset request message is generated by an execution logic data transceiver terminal in a terminal device, and the reconfiguration of a target link is negotiated with a network access device through link reset information in the link reset request message. The network access equipment can determine whether to accept the reconfiguration of the target link according to the link resetting information. The terminal equipment and the network access equipment can acquire the negotiation result of the reconfiguration of the target link through the link resetting result information in the link resetting response message, and update the link mapping relation stored in the terminal equipment. The terminal equipment with more than two logic data receiving and transmitting terminals and the network access equipment with more than two logic access points can mutually negotiate the reconfiguration of a target link through a link reset request message and a link reset response message, thereby realizing the reconfiguration of a data transmission link under the scene of a multi-link system.

And under the condition that the link resetting result information comprises second authentication and authentication information, generating a communication key for data safety transmission by utilizing data generated and prestored by the terminal equipment and combining the second authentication and authentication information and the like. Fig. 12 is a flowchart of another embodiment of a method for configuring links in a multilink system according to the first aspect of the present application. Fig. 12 is different from fig. 2 in that the link configuration method shown in fig. 12 may further include step S205 to step S207.

In step S205, a first MAC address is obtained according to the logical terminal identifier of the logical data transceiver terminal in the target link.

The first MAC address includes a MAC address of a logical data-transceiving terminal in the target link.

In some examples, the logical terminal identification includes a MAC address, and the MAC address of the logical data-transceiving terminal in the target link may be directly taken as the first MAC address.

In some examples, the logical terminal identifier does not include a MAC address, but the logical terminal identifier and the MAC address of the logical data transceiver terminal have a first correspondence, and then a MAC address corresponding to the logical terminal identifier of the logical data transceiver terminal in the target link may be queried in the first correspondence according to the logical terminal identifier of the logical data transceiver terminal in the target link, and the MAC address may be used as the first MAC address.

In step S206, a second MAC address is obtained according to the logical access point identifier of the logical access point in the target link.

The second MAC address includes a MAC address of a logical access point in the target link.

In some examples, the logical access point identification includes a MAC address, and the MAC address of the logical access point in the target link may be directly used as the second MAC address.

In some examples, the logical access point identifier does not include a MAC address, but a second correspondence exists between the logical access point identifier and the MAC address of the logical access point, and then a MAC address corresponding to the logical access point identifier of the logical access point in the target link may be queried in the second correspondence according to the logical access point identifier of the logical access point in the target link, and the MAC address is used as the second MAC address.

In step S207, a communication key is generated using the second authentication information, the generated first authentication information, a pre-stored Pairwise Master Key (PMK), the first MAC address, and the second MAC address.

The first authentication information may be a random number locally generated by the terminal device. The second authentication and authorization information may be a random number generated by the network access device and transmitted through the link reset result information. The pairwise master key may be stored locally at the terminal device in advance. The algorithm used to generate the communication key is not limited herein, and may be set according to specific scenarios and requirements. The traffic key is used for data transmission in the target link. When the target link is used for data transmission, the communication key can be used for encrypting the data to be transmitted so as to ensure the security of the data transmission.

Fig. 13 is a flowchart of a method for configuring links in a multilink system according to a further embodiment of the present invention. Fig. 13 is different from fig. 2 in that step S204 in fig. 2 can be specifically subdivided into one or more of step S2041 to step S2043 in fig. 13.

In step S2041, in the case that the link resetting information is used to negotiate with the network access device to add or modify the target link, and the link resetting result information represents that the reconfiguration of the target link is accepted, the mapping relationship between the logical data transceiver terminal and the logical access point in the target link is added or modified in the link mapping relationship.

Specifically, in the case that the link resetting information includes a valid addition operation information element or the resetting operation type identifier in the link resetting information includes an addition operation identifier, and the resetting negotiation result information in the link resetting result information includes a negotiation acceptance identifier, the mapping relationship between the logical data transceiver terminal and the logical access point in the target link may be added in the link mapping relationship. For example, in the case where the reset operation type identifier in the link reset information includes the Add operation identifier Add, and the reset negotiation result information in the link reset result information includes the negotiation acceptance identifier, and the added target link is a link formed by the logical data transceiver terminal STA3 and the logical access point AP3, the mapping relationship between the logical data transceiver terminal STA3 and the logical access point AP3 may be added in the link mapping relationship.

Specifically, in the case that the link resetting information includes a valid modification operation information element or the reset operation type identifier includes a modification operation identifier, and the reset negotiation result information includes a negotiation acceptance identifier, the mapping relationship between the logical data transceiver terminal and the logical access point in the target link may be modified in the link mapping relationship. For example, in the case that the reset operation type identifier in the link reset information includes the modification operation identifier Modify, and the reset negotiation result information in the link reset result information includes the negotiation acceptance identifier, the target link before modification is the link formed by the logical data transceiver terminal STA2 and the logical access point AP2, and the target link after modification is the link formed by the logical data transceiver terminal STA2 and the logical access point AP3, the mapping relationship between the logical data transceiver terminal STA2 and the logical access point AP2 may be modified to the mapping relationship between the logical data transceiver terminal STA2 and the logical access point AP3 in the link mapping relationship.

In step S2042, in the case that the link resetting information is used to negotiate with the network access device to delete the target link, and the link resetting result information indicates that the reconfiguration of the target link is accepted, the mapping relationship between the logical data transceiver terminal and the logical access point in the target link is deleted in the link mapping relationship.

Specifically, in the case that the link resetting information includes a valid deletion operation information element or the resetting operation type identifier in the link resetting information includes a deletion operation identifier, and the resetting negotiation result information in the link resetting result information includes a negotiation acceptance identifier, the mapping relationship between the logical data transceiver terminal and the logical access point in the target link may be deleted in the link mapping relationship. For example, in the case that the reset operation type identifier in the link reset information includes the Delete operation identifier Delete, and the reset negotiation result information in the link reset result information includes the negotiation acceptance identifier, and the target link is a link formed by the logical data transceiver terminal STA2 and the logical access point AP2, the mapping relationship between the logical data transceiver terminal STA2 and the logical access point AP2 may be deleted in the link mapping relationship.

In step S2043, the status identifier of the logical data transceiver terminal in the target link in the link mapping relationship is updated when the link resetting information is used to negotiate with the network access device to suspend or resume the target link and the link resetting result information represents that the reconfiguration of the target link is accepted.

Specifically, the status identifier of the logical data transceiver terminal in the target link in the link mapping relationship may be updated from the active status identifier to the inactive status identifier when the link resetting information includes a valid suspend operation information element or the resetting operation type identifier in the link resetting information includes a suspend operation identifier, and the resetting negotiation result information in the link resetting result information includes a negotiation acceptance identifier.

Specifically, the status identifier of the logical data transceiver terminal in the target link in the link mapping relationship may be updated from the inactive status identifier to the active status identifier when the link resetting information includes a valid recovery operation information element or the reset operation type identifier in the link resetting information includes a recovery operation identifier, and the reset negotiation result information in the link resetting result information includes a negotiation acceptance identifier.

Corresponding to the configuration of the pause or the recovery of the target link, the method of the terminal equipment for sending the cache data of the target link can be determined. Fig. 14 is a flowchart of a method for configuring links in a multilink system according to a further embodiment of the present invention. Fig. 14 is different from fig. 2 in that the link configuration method shown in fig. 14 may further include step S208 and/or step S209.

In step S208, in a case that the link resetting information is used to negotiate with the network access device to suspend the target link, and the link resetting result information indicates that the reconfiguration of the target link is accepted, sending, by any logical data transceiver terminal in the terminal device except the logical data transceiver terminal in the target link, the buffered data of the target link.

Under the condition that the target link is suspended, the data which is originally required to be sent in the target link cannot be sent through the target link, and the data which is originally required to be sent in the target link is the cache data of the target link. In order to ensure that the cached data can be continuously sent to the network access device by the terminal device, the cached data can be sent by other logical data transceiver terminals in the terminal device except the logical data transceiver terminal in the target link. In some examples, the buffered data may be transmitted by an executive logic data transceiver terminal, which is not limited herein.

In step S209, in a case that the link resetting information is used to negotiate with the network access device to recover the target link, and the link resetting result information indicates that the reconfiguration of the target link is accepted, the logical data transceiver terminal in the target link sends a buffered data trigger message to the logical access point in the target link.

The link reset result information may also include a cached data identification, which may be used to indicate that the target link has cached data. In the case that the target link has the buffered data, a buffered data trigger message may be sent by the logical data transceiving terminal in the target link to the logical access point in the target link. The buffered data trigger message is used for triggering the transmission of the buffered data in the target link. Specifically, the buffered data trigger message may be a PS-POLL message, which is not limited herein.

In some examples, the logical data-transceiving terminal in the terminal device may support different operating frequencies, and the network access device may be notified via a connection request message prior to performing the reconfiguration of the target link. Specifically, the terminal device may send a connection request message to the network access device. The connection request message may specifically be a connection request message sent by the terminal device initially establishing a connection with the network access device, and is not limited herein. The connection request message may include the logical data-transceiving terminal identification and the operating frequency information of the logical data-transceiving terminal. The operating frequency information is used to indicate the operating frequency. The operating frequency may specifically include a set of frequency bands of the operating frequency, and is not limited herein. The connection request message may further include a variable operating frequency support flag indicating whether the logical data-transceiving terminals support different operating frequencies. The variable operating frequency support identifier may include, but is not limited to, numbers, letters, other characters, and the like. For example, the variable operating frequency support identifier of the logical data transceiver terminal is 1, which indicates that the logical data transceiver terminal supports different operating frequencies; the variable operating frequency support flag of the logical data transceiving terminal is 0, indicating that the logical data transceiving terminal does not support a different operating frequency.

Fig. 15 is a schematic diagram of an example of a connection request message provided in an embodiment of the present application. As shown in fig. 15, the connection request message includes a logical data transceiving terminal identity STA ID, a variable operating frequency support identity Flex OF indication, and an operating frequency information Supported OF set. The logic data transceiver terminal is identified as STA1_ address, the variable working frequency support identifier is 1, and the working frequency information is {2.4GHz, 5GHz }. The operating frequency information is {2.4GHz, 5GHz } indicating that the logical data transceiver terminal STA1 can support a frequency band of an operating frequency of 2.4GHz and a frequency band of 5 GHz.

In some examples, a logical data-transceiving terminal in a terminal device may obtain system information of a logical access point in a target link prior to reconfiguration of the target link. Specifically, the logical data transceiver terminal in the terminal device may acquire the system information of the logical access point through a broadcast message of the network access device. The broadcast message may specifically be a beacon message or a probe response message. The logical data transceiver terminal in the terminal device may also obtain the system information of the logical access point through a connection request response message sent by the network access device. The manner in which the logical data transmitting and receiving terminal in the terminal device acquires the system information of the logical access point is not limited herein.

Fig. 18 is a flowchart of a method for configuring links in a multilink system according to a second aspect of the present application. Fig. 18 is different from fig. 16 in that the link configuration method shown in fig. 18 may further include step S307 and/or step S308.

In step S307, in the case that the link resetting information is used to negotiate with the network access device to delete the target link, and it is determined to accept the reconfiguration of the target link characterized by the link resetting information, the stored link information of the logical data transceiver terminal in the target link is deleted.

Specifically, the logical access point corresponding to the logical access point identifier, that is, the logical access point in the target link may be determined according to the logical access point identifier in the deletion operation information element in the link resetting information or the logical access point identifier of the target link information in the link resetting information.

When the target link is suspended, the data to be sent in the target link can be cached locally, and the data to be sent in the target link cached locally is the cached data. The buffered data may be subsequently sent over other links that are not suspended, or the buffered data may be sent after waiting for the target link to resume.

In step S310, in the case that the link resetting information is used to negotiate with the network access device to recover the target link, and it is determined to accept the reconfiguration of the target link characterized by the link resetting information, a cached data identifier is added to the link resetting response message.

The cache data identification is used for indicating that the target link has cache data. Under the condition that the target link is recovered and the target link has the cache data, the terminal equipment can be informed that the target link has the cache data by adding the cache data identification in the link resetting response message, so that the terminal equipment can conveniently determine which mode is adopted to receive and send the cache data.

In some examples, the logical data-transceiving terminal in the terminal device may support different operating frequencies, and the network access device may be notified via a connection request message prior to performing the reconfiguration of the target link.
