detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

To facilitate a better understanding of the present invention, the implementation process of the cellular mobile network and WLAN network fusion communication in the prior art involved in the background art is described below.

It should be noted that the cellular mobile network involved in the full text may be an LTE network, or a Wideband Code Division Multiple Access (WCDMA) network, or a Wideband Code Division Multiple Access (CDMA). The network, or other cellular mobile network, is described by using the LTE system as an example, and is not specifically limited to the type of the cellular mobile network.

It should be noted that the cellular mobile network is an LTE network, and the LWA technology of the LTE network and the WLAN network is taken as an example to describe the implementation process of the cellular mobile network and the WLAN network, and the cellular mobile network type is not Specifically limited.

Specifically, FIG. 1 illustrates a network architecture of the LWA technology. The implementation process of the LWA technology is divided into a WT addition process and a data transmission process.

As shown in FIG. 2, the WT addition process may include:

S201. The eNB requests the UE to report the capability of the UE.

Wherein the capability is used to determine whether the UE has LWA capabilities.

Optionally, S201 may be executed when the UE is powered on, or may be in the UE. Before sending data, it is not specifically limited, and can be set according to actual needs.

S202. The UE reports capability information.

The capability information may include an LWA capability of the UE, and may also include a WLAN frequency band supported by the UE.

Optionally, the capability information may further include a MAC address used by the UE to perform WLAN communication.

It should be noted that in order to protect user information security and prevent WLAN monitoring, WLAN communication is generally performed by masquerading a MAC address.

Optionally, the spoofed MAC address of the UE may be obtained by performing an algorithm (for example, a hash algorithm, etc.) on the fixed MAC address of the UE.

It should be noted that S201 and S202 are not executed every time the WT is added. If the eNB and the UE have already interacted with each other, they may not be executed.

S203. The eNB sends a WLAN measurement configuration to the UE.

The measurement configuration includes at least measuring an event related threshold condition. When the UE's measured value of the measurement object satisfies the measurement event related threshold condition in the measurement configuration, the UE sends a measurement report to the eNB.

It should be noted that the threshold condition may be determined according to an algorithm, or may be manually configured, and is not specifically limited.

Optionally, in S203, the WLAN measurement configuration may be sent to the UE by using a Radio Resource Control (RRC) configuration message.

Optionally, the measurement configuration may further include one or more of the following information: a measurement frequency band, a measurement report configuration, a measurement quantity, and a measurement identifier.

It should be noted that the content included in the measurement configuration may be set according to actual requirements, and is not specifically limited.

S204. The UE returns an acknowledgement message to the eNB.

The confirmation message is used to indicate that the UE has successfully received the measurement configuration.

S205. The UE acquires information about the WLAN according to the measurement configuration.

Specifically, in S205, the UE performs measurement according to the indication of the measurement configuration, and obtains Take the measured value as the information of the WLAN and judge whether to send the measurement report.

When the UE determines that the acquired information of the WLAN satisfies the measurement event, executing S206 sends a measurement report to the eNB.

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

The measurement report includes the measurement object and corresponding measurement values.

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

It should be noted that, if the capability information in the S202 includes the MAC address used by the UE to perform 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, where 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 needs, and is not specifically limited.

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

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

S208. The eNB determines that the specific bearer of the UE sends a WT addition request to the WT to which the AP in the AP group belongs.

The WT addition request is used to request a WLAN resource from the WT. A general packet radio service tunneling protocol for the user plane (GTP-U) tunnel is established for requesting a specific bearer with the WT for the UE.

The WT addition request includes a MAC address used by the UE to perform WLAN communication, and at least one bearer that the eNB decides to transmit data to the UE through the WLAN.

Optionally, the MAC address that is used by the UE in the WT addition request to perform WLAN communication may be reported by the UE in the capability information in S202, or may be The UE is reported in the measurement report in S206, or the UE may report the report through a separate report message before S208.

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

S209. The WT determines that the bearer of the resource is allocated, and the Tunnel Endpoint Identifier (TEID) is allocated.

The WT determines that one or more bearers can allocate resources for the at least one bearer included in the WT addition request message, and allocates a TEID to each of the allowed bearers.

In S209, after the WT allocates the TEID, the WT can establish a correspondence between the MAC address and the TEID of the WLAN, so that when the data is received from the tunnel indicated by the TEID, the WT passes the correspondence between the MAC address and the TEID. It is possible to know which UE the received data is sent to.

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

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

The WT Add Request Reply message includes a WT-determined bearer that allows allocation of WLAN resources, and a TEID allocated for each bearer that is allowed to allocate WLAN resources.

Specifically, after receiving the WT addition request reply message, the eNB obtains a mapping relationship between the MAC address of the UE and the TEID of the UE, the Cell Radio Network Temporary Identifier (C-RNTI).

S211. The eNB sends an 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 (identifying the UE 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 GTP-U header is added. After receiving the GTP-U packet, the WT can know which UE belongs to the GTP-U packet according to the mapping relationship between the TEID and the MAC address, and then send the corresponding AP to the corresponding AP.

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

At this point, the WT process is completed, and the LWA technology can be used for data transmission.

In the network architecture shown in FIG. 1, the data transmission process is: data sent to the UE arrives at the eNB via the core network, and the eNB sends a part of data to the UE through the LTE link, and a part of the data passes through the WLAN link (WT and AP). Send to the UE; uplink data transmission is similar.

In the process of performing data transmission, when the UE determines that the accessed WLAN link fails (exemplary, the WLAN link that the UE accesses due to the MAC address change of the WLAN fails), the UE should be sent to the UE. Data cannot be sent to the UE, causing a large amount of data loss.

In order to protect user information security and prevent WLAN monitoring, the UE can communicate with the WLAN by using a masquerading MAC address. Since the masquerading MAC address is not fixed, in the process of performing the LWA, once the masquerading 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 that the UE accesses is caused. failure.
