Detailed Description
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for controlling aggregation of frames during handover of an access point. The method shown in fig. 2 can be implemented under the WLAN network architecture shown in fig. 1, and specifically, the terminal switches from a first access point AP0 to a second access point AP1, and the method shown in fig. 2 includes the following steps:
when the wireless controller determines to switch the terminal from the AP0 to the access point AP1, the wireless controller transmits a switch request to the access point AP0 at step S201.
The wireless controller may use a handover algorithm to determine whether to change to the AP served by the terminal and, if so, to which AP the terminal is handed over. The wireless controller may be a single physical device or a combination of multiple devices.
Step S202, APO reads the state of the aggregation frame of the terminal. The status of the aggregation frame is a set of statuses of whether each frame in the aggregation frame is successfully transmitted. The status of the aggregate frame may be represented by a sequence number of a first frame in the aggregate frame and a bitmap of whether each frame was successfully transmitted. The first bit of the bitmap corresponds to the first frame in the aggregated frame, and the subsequent bits sequentially correspond to frames of which the sequence numbers are continuously increased on the basis of the sequence number of the first frame. The value of each bit of the bitmap indicates whether the corresponding frame was successfully transmitted. Of course, the set of states of whether each frame in the aggregate frame is successfully transmitted may also be represented by other means, for example, by a frame number and whether the frame number is successfully transmitted.
Step S203, the AP0 sends a handover response to the wireless controller, where the handover response includes: status of the aggregated frame.
In step S204, the wireless controller transmits a handover notification to the AP 1.
Step S205, the AP1 stores the status of the aggregation frame, and transmits a handover confirmation to the radio controller.
In step S206, the wireless controller transmits a deletion notification to the AP0, the deletion notification indicating a state where the AP0 deletes the aggregated frame.
The method shown in fig. 2 still performs the reception or transmission of the aggregation frame with the terminal by the AP0 when performing step S204 and step S205. The process of the AP0 sending the aggregation frame to the terminal is described below by taking the sending of the aggregation frame as an example, where the sending of the aggregation frame specifically includes:
the AP0 transmits the aggregation frame to the terminal, and the terminal transmits a Block acknowledgement (Block Ack) message to the AP 0. The Block Ack message may include: a bitmap. The AP0 determines from the bitmap whether the MPDU within the aggregated frame was successfully transmitted. The AP0 retransmits the MPDU that was not successfully transmitted.
The transmission flow of the aggregation frame is described below by taking an actual example, where the number of MPDUs included in the aggregation frame is 5 as an example (for convenience of description, 5 MPDUs are identified by MPDU1, MPDU2, MPDU3, MPDU4, and MPDU 5), and in an actual application, other values may also be used. When the number of MPDUs contained in the aggregate frame is 5, the number of significant bits thereof may be the first 5 bits of 64 bits, and each significant bit represents a corresponding MPDU in the aggregate frame. For example, bit 1 indicates whether the transmission of the first MPDU in the aggregate frame is successful, where bit 1 indicates that the transmission is successful, and bit 0 indicates that the transmission is unsuccessful (of course, 0 may be set as successful in transmission and bit 1 as unsuccessful in transmission at the manufacturer), and for convenience of description, the following bitmap only provides a significant bit, i.e., 5 bits. The specific transmission flow of the aggregated frame may include: the AP0 issues an aggregation frame 1 to the terminal, where the aggregation frame 1 includes 5 MPDUs, and the terminal sends a Block acknowledgement (Block Ack) message to the AP0, where a value of a bitmap in the Block acknowledgement may be: 11101, the AP0 retransmits MPDU4 to the terminal if the APO knows from the bitmap that the transmission of MPDU4 was unsuccessful.
When the above switching method is performed in step S204 and step S205, the AP0 and the terminal are still performing the transmission or reception of the aggregation frame, the status of the aggregation frame between the AP0 and the terminal is stopped when the AP0 deletes the user context information, and the status of the aggregation frame of the terminal is the status in step S206, and the status of the aggregation frame of the switching response, that is, the status of the aggregation frame of the AP1, is the status in switching response (that is, the status in step S203). Since the terminal does not sense the switching of the access point, the terminal continues to transmit the aggregation frame after switching to the AP1, at this time, the state of the aggregation frame in the AP1 is not synchronized with the state of the terminal aggregation frame, and the terminal does not retransmit the aggregation frame transmitted to the AP0 in step S204 and step S205 to the AP1, the aggregation frame transmitted to the AP0 by the terminal in step S204 and step S205 loses packet.
Referring to fig. 3, fig. 3 is a flowchart of a method for controlling aggregation of frames in an access point handover according to an embodiment of the present invention, where the method shown in fig. 3 can be implemented under the WLAN network architecture shown in fig. 1, and specifically, the terminal is handed over from the AP0 to the AP1, and the method shown in fig. 3 includes the following steps:
step S301, when the wireless controller decides that the terminal needs to be switched from the AP0 to the AP1 through a switching algorithm, the wireless controller sends a switching request to the AP 0.
In step S302, the AP0 stops sending the aggregation frame to the terminal according to the switching request, and sends a delete block acknowledgement request (DELBA request) to the terminal. The delete block ack request is used to instruct the AP0 to terminate sending block acks to the terminal. Because the acknowledgement for the aggregated frame is a block acknowledgement, the terminal knows that the AP0 will stop sending the aggregated frame after terminating sending the block acknowledgement. Optionally, the AP0 sends another delete block acknowledgement request to the terminal, the delete block acknowledgement request instructing the terminal to terminate sending block acknowledgements.
Step S303, the APO sends a handover response to the wireless controller, where the handover response may include: an add block acknowledgement request send indication.
The value of the add block ack request transmission indication may be "transmit" or "not transmit". If the value of the added block ack request transmission instruction is "transmission", the AP1 that received the added block ack request transmission instruction transmits an added block ack request to the terminal.
Alternatively, the add block acknowledgement request transmission indication may be a combination of a terminal's support capability for aggregated frames and a terminal's de-enabled status for aggregated frames. The support capability of the terminal for the aggregation frame may include two types, that is, the terminal supports the aggregation frame and the terminal does not support the aggregation frame. The disable state of the terminal aggregation frame may also include two states, a disable state and an enable state, where the disable state indicates that the terminal does not transmit or receive the aggregation frame, and the enable state indicates that the terminal is transmitting or receiving the aggregation frame. The AP1 receiving a combination of the support capability of the terminal for the aggregated frame and the disable state of the terminal aggregated frame, when determining that the support capability of the terminal for the aggregated frame is support and the disable state of the terminal aggregated frame is disable, the AP1 transmits an add block determination request to the terminal.
In step S304, the wireless controller transmits a handover notification to the AP 1. The handover notification may include: an add block acknowledgement request send indication.
Step S305, AP1 returns a handover confirmation to the wireless controller.
In step S306, the wireless controller issues a deletion notification to the AP0, where the deletion notification is used to notify the AP0 of the deletion of the aggregated frame.
In the step S306, the status of the aggregation frame is deleted, that is, the bitmap and the MPDU sequence number of the aggregation frame are deleted, so that when the terminal switches back to the AP0, confusion between the bitmap and the MDPU sequence number is avoided, and the reliability of switching is effectively improved.
Step S307, if the disable state of the terminal aggregation frame is disable and the terminal supports the aggregation frame, the AP1 sends an add block acknowledgement request (ADDBA request) to the terminal. The add block acknowledgement request is used to instruct the terminal to send a block acknowledgement to the AP 1. Because the acknowledgement for the aggregate frame is a block acknowledgement, the terminal knows that the AP1 sent the block acknowledgement and can send the aggregate frame. Optionally, the AP1 sends another send block acknowledgement request to the terminal, the send block acknowledgement request instructing the terminal to send a block acknowledgement.
In step S308, the AP1 receives the add block acknowledgement response (ADDBA response) sent by the terminal, and the AP1 sends the aggregation frame to the terminal.
In the embodiment of the present application, when controlling the aggregation frame during the access point switching, when the AP0 receives the switching request, the AP stops sending the aggregation frame to the terminal, and sends the delete fast acknowledgement request to the terminal so that the terminal also stops sending the aggregation frame to the AP0, so in the subsequent steps, the AP0 does not send or receive the aggregation frame with the terminal, and therefore the state of the aggregation frame does not change. After the terminal is switched to the AP1, the terminal renegotiates with the AP1 to continue transmission or reception of the aggregated frame, and since the terminal has stopped transmitting the aggregated frame to the AP0, the state of the aggregated frame does not change, and the AP1 does not have a situation in which the aggregated frame is lost due to state inconsistency, so that it has an advantage of reducing the number of packet losses.
