S206, the UE sends a measurement report to the eNB.

Wherein, the measurement report includes measurement objects and corresponding measurement values.

Optionally, the measurement report may further include a MAC address used by the UE for WLAN communication.

It should be noted that, if the capability information in S202 includes the MAC address used by the UE for WLAN communication, the capability information in S206 does not need to be included.

S207 , the eNB selects an AP group for the UE according to the measurement report.

The eNB may select an AP group for the UE according to the measurement report, and the AP group includes N APs belonging to the same WT.

It should be noted that the value of N can be set according to actual requirements, which is not specifically limited.

Optionally, the eNB may select N APs with the best signal quality and performance as the AP group selected for the UE according to the measurement report.

Optionally, the eNB may also select N APs with the best signal quality and performance as the AP group selected for the UE according to the measurement report and in combination with the capabilities of each AP obtained by the eNB through interaction with the WT.

S208 , the eNB decides to send a WT addition request to the WT to which the AP in the AP group belongs to the specific bearer of the UE.

Wherein, the WT addition request is used to request the WT for WLAN resources. It is used to request the establishment of a General Packet Radio Service Tunnelling Protocol (General Packet Radio Service Tunnelling Protocol for the user plane, GTP-U for short) tunnel between the WT and the WT for a specific bearer of the UE.

The WT addition request includes a MAC address used by the UE for WLAN communication, and at least one bearer decided by the eNB to send data to the UE through the WLAN.

Optionally, the MAC address used by the UE for WLAN communication included in the WT addition request may be reported by the UE in the capability information in S202, or may also be reported by the UE in the measurement report in S206, or, It may also be that the UE reports through a separate report message before S208.

The at least one bearer that the eNB decides to send data to the UE through the WLAN is selected by the eNB from all the bearers that send data to the UE through a preset algorithm, which is not specifically limited.

S209, the WT decides to allow the bearer of the allocation resource, and allocates a tunnel endpoint identifier (Tunnel EndpointIdentifier, TEID for short).

Wherein, the WT decides that one or more bearers can be allocated resources from at least one bearer included in the WT add request message, and allocates a TEID to each allowed bearer.

In S209, after the WT allocates the TEID, the corresponding relationship between the MAC address and the TEID of the UE for WLAN can be established. In this way, when data is received from a tunnel indicated by a TEID, the WT uses the corresponding relationship between the MAC address and the TEID, Then, the UE to which the received data is sent can be known.

S208 and S209 complete the establishment of the GTP-U tunnel for the specific bearer of the UE.

S210. The WT sends a WT add request reply message to the eNB.

Wherein, the WT add request reply message includes the bearer that the WT decides to allow allocation of WLAN resources, and the TEID allocated for each bearer that allows allocation of WLAN resources.

Specifically, after receiving the WT add request reply message, the eNB obtains the UE's Cell Radio Network Temporary Identifier (C-RNTI for short), and the mapping relationship between the UE's MAC address and the TEID.

S211. The eNB sends the AP group to the UE.

S212, the UE performs WLAN access.

Exemplarily, when the eNB sends the data of the specific bearer of the UE (the UE is identified by the C-RNTI identifier on the eNB side) to the WT, the data is packaged according to the GTP-U protocol, and the corresponding data is added to the GTP-U header. After receiving the GTP-U packet, the WT can know which UE the data in the GTP-U packet belongs to according to the mapping relationship between the TEID and the MAC address, and then send it to the corresponding AP.

S213. The WT sends a WT access confirmation message to the eNB.

So far, the WT addition process is completed, and the LWA technology can be used for data transmission.

In the network architecture shown in Figure 1, the data transmission process is: the data sent to the UE reaches the eNB through the core network, the eNB sends part of the data to the UE through the LTE link, and part of the data through the WLAN link (WT and AP) Sent to UE; uplink data transmission is similar.

In the process of data transmission, when the UE determines that the WLAN link to access fails (for example, the WLAN link that the UE accesses fails due to the change of the MAC address of the WLAN), it results in the failure of the WLAN link that should be sent to the UE. Data cannot be sent to the UE, resulting in a large amount of data loss.

Among them, in order to protect the security of user information and prevent WLAN monitoring, the UE may use a fake MAC address to communicate with the WLAN. Since the spoofed MAC address is not fixed, during the LWA process, once the spoofed MAC address of the UE changes, when the eNB sends the data of the UE to the WT, the WT cannot find the UE, and the WLAN link accessed by the UE will be caused. fail.
