Description

Multi-flow polymerization method, device and system

Technical field

The present invention relates to the field, and in particular, to a multi-flow polymerization method, apparatus and system.

Background technique

At present, due to the rapid development of smart terminals and mobile applications, mobile data traffic has increased dramatically, making it increasingly difficult for existing mobile networks to meet the demand for data traffic growth. Therefore, mobile operators hope to use the non-the 3rd Generation Partner Project (non-3) network to carry part of the existing network traffic, and realize the inter-3GPP network and the non-3GPP network. Cooperation to alleviate the traffic load on the live network. For example, the long-term evolution (English: Long Term Evolution, LTE for short) network and the wireless local area network (English: Wireless Local Area Networks, WLAN for short) are currently being collaborated.

Business diversion is a key issue when considering cooperation between 3GPP networks and non-3GPP networks. The service offloading mainly refers to the situation in which all or part of the traffic of the user needs to be offloaded from one radio access technology (Radio Access Technology, RAT for short) to another RAT. For example, when considering the cooperation between the LTE network and the WLAN network, when the LTE network service is overloaded, all or part of the traffic of the users in the WLAN coverage may be offloaded to the WLAN network, thereby enabling the user to have a better experience. .

In the scenario of cooperation between the LTE network and the WLAN network, it is assumed that the user equipment supports the LTE network and the WLAN network at the same time, and the WLAN network mainly refers to the basic architecture, that is, the user equipment needs to pass the WLAN wireless access point (English: Wireless) Access Point (AP) accesses the WLAN network or accesses the WLAN network through the WLAN virtual AP. The LTE evolved base station (English: evolved Node B, eNB for short) is not in the same node (non-collocated). The virtual AP is a logical entity that exists in a physical AP. When a physical AP supports multiple virtual APs, each virtual AP is an independent physical AP to the user equipment. At this time, if the service data of the LTE network is to be offloaded to the WLAN network, the eNB needs to exchange information with the WLAN AP.

In the process of implementing the present invention, the inventors have found that the prior art has at least the following problems:

In the prior art, the WLAN network accesses through a packet data network gateway (English: Packet Data Network-Gateway, PDN-GW for short) or an evolved packet data gateway (English: Evolved Packet Data Gateway, ePDG) and PDN GW. LTE network. If the eNB wants to exchange information with the WLAN AP, the network node that passes through includes the eNB, the Mobility Management Entity (MME), the Serving GateWay (SGW), and the PDN- The GW and the WLAN have high system complexity. Therefore, when signaling is transmitted, there are many signaling forwarding nodes, resulting in excessive signaling, which increases the signaling forwarding delay.

In the embodiment of the present invention, the user equipment (English: User Equipment, UE for short) may also be called a mobile terminal (English: Mobile Terminal), a mobile user equipment, etc., and may be accessed via a radio access network (English: Radio Access) Network, referred to as: RAN), communicates with one or more core networks, which may be mobile terminals, such as mobile phones (or "cellular" phones) and computers with mobile terminals, for example, portable, pocket-sized Mobile devices that are built-in, built-in, or in-vehicle, which exchange language and/or data with the wireless access network, and are not limited by the present invention.

In the embodiment of the present invention, the 3GPP access network entity may be a base station device, such as a base transceiver station in GSM or CDMA (English: Base Transceiver Station, BTS for short), or a Node B in WCDMA (English: Node B) may also be an eNB in LTE, and the invention is not limited. The 3GPP access network entity may also be a control node of various access network nodes, such as a radio network port controller (English: Radio Network Controller, RNC for short) in UMTS, or a controller that manages multiple small base stations.

In the embodiment of the present invention, the non-3GPP access network entity may be an access point in the Wimax network, or may be a WLAN AP, or may be an AC in the WLAN or other separately deployed entities.

In the embodiment of the present invention, the non-3GPP access network entity has two network architectures: an autonomous management architecture and a centralized management architecture. The self-management architecture is also called the "fat" AP architecture. The WLAN AP is responsible for user equipment access, user equipment disconnection, authority authentication, security policy enforcement, data forwarding, data encryption, network management, etc., and autonomously controls the configuration of the WLAN AP. wireless function. The centralized management architecture is also called the “thin” AP architecture. The management rights are generally concentrated on the wireless controller (English: Access Controller, AC for short). The AC manages the IP address, authentication, and encryption of the user equipment. The WLAN AP only has encryption, data forwarding, and radio frequency functions, and cannot work independently. The Control and Provisioning of Wireless Access Points (CAPWAP) specification protocol is adopted between the WLAN AP and the AC. Optionally, the foregoing WLAN AP may be integrated with the base station. Because the embodiment of the present invention mainly relates to the data forwarding function of the WLAN AP, the two network architectures of the foregoing WLAN AP can be applied.

The multi-stream aggregation application scenario of the embodiment of the present invention is described below by taking the LTE RAN and the WLAN as examples.

Wherein, when the 3GPP access network is an LTE RAN, the 3GPP access network entity may be an eNB or a centralized node, for example, a single radio access network control (English: Single Ran Control, SRC) node, the node is a The centralized node on the RAN side can manage RAN side nodes, such as eNB and AP. When the non-3GPP access network is a WLAN, the non-3GPP access network entity may be an AP, an AC, or a separately deployed entity.

Specifically, in the first scenario, as shown in FIG. 1 , the eNB and the AC are not in the same node, and the Xw interface may be set between the eNB and the AP, and the eNB and the AP are connected through the Xw interface.

In the second scenario, as shown in FIG. 2, the eNB and the AC are in the same node, and the Xw interface can be set between the eNB and the AP, and the eNB and the AP are connected through the Xw interface.

In the third scenario, as shown in FIG. 3, the eNB and the AC are not in the same node, and the Xw interface can be set between the eNB and the AC, and the eNB and the AC are connected through the Xw interface.

In the fourth scenario, as shown in FIG. 4, the Xw interface may be set between an eNB and a convergence function entity or a coordination function entity or an interworking function entity (such as IWK func, interworking function) in the WLAN network, and the eNB and the eNB. The aggregation function entity in the WLAN network is directly connected, and the aggregation function entity is a separately deployed entity in the WLAN.

In the fifth scenario, as shown in FIG. 5, the Xw interface may be set in a centralized node on the RAN side (such as a central node) and an aggregation function entity or a coordination function entity or an interworking function entity (such as IWK) in the WLAN network. Between func), the eNB is connected to the aggregation functional entity in the WLAN network through the centralized node.

The LTE network and the WLAN network are taken as an example to describe the data transmission process in the application scenario provided by the embodiment of the present invention:

In the embodiment of the present invention, for the downlink data (hereinafter referred to as downlink transmission) that the eNB transmits to the user equipment, the downlink data may include the first partial downlink data and the second partial downlink data. The eNB diverts the first part of the downlink data to the WLAN AP, and then sends the data to the user equipment by using the WLAN AP; the second part of the downlink data is directly sent by the eNB to the user equipment through the wireless cellular network, so that At the same time, the transmission capacity of the wireless cellular network (ie, the aforementioned LTE network) and the WLAN network is utilized to achieve a higher downlink transmission rate of the user equipment.

For uplink data transmitted by the user equipment to the eNB (hereinafter referred to as uplink transmission), the uplink data may include the first partial uplink data and the second partial uplink data. The user equipment offloads the first part of the uplink data to the WLAN AP, and then sends the data to the eNB via the WLAN AP. The second part of the uplink data is directly sent by the user equipment to the eNB through the wireless cellular network, so that the transmission capability of the wireless cellular network and the WLAN network can be utilized at the same time. To achieve higher user equipment uplink peak transmission rate.

During the downlink transmission, the eNB may transmit the data that needs to be offloaded to the WLAN AP, and send the data to the user equipment through the WLAN AP. During the uplink transmission, the user equipment may send the data that needs to be offloaded to the WLAN AP, and pass the WLAN AP. The data is sent to the eNB.

The second eNB protocol stack may include a user plane protocol stack, and may also include a control plane protocol stack. In the present invention, the user plane protocol stack transport layer uses a GPRS channel protocol-user plane GPRS tunneling protocol (English: GPRS Tunnelling Protocol-User Plane) , referred to as: GTP-U) (as shown in Figure 6b) or 802.3 protocol (as shown in Figure 6a), as shown in Figure 7, In the present invention, the control plane protocol stack transport layer uses the Stream Control Transmission Protocol (SCTP) protocol, and the application layer adopts the newly defined wireless LAN application part (English: Wireless LAN Application Part, WLAP for short). )protocol. The second eNB protocol stack may be aggregated in PDCP or RLC or MAC of the first eNB protocol stack. The first eNB protocol stack can be offloaded at PDCP or RLC or MAC. In this embodiment, the PDCP layer of the first base station protocol stack is aggregated and aggregated as an example, but the present invention does not limit this.

Then, the configuration of the protocol stack in the WLAN AP is described (if the interface is between the eNB and the AC, then here is the protocol stack of the AC, the AC to the AP follows the protocol stack of the existing wireless local area network communication, and the rest are similar):

The WLAN AP protocol stack has a first WLAN AP protocol stack and a second WLAN AP protocol stack. The first WLAN AP protocol stack is configured to implement data processing for communication with the eNB on the WLAN AP side, where the second WLAN AP protocol stack is configured to implement data processing for communication with the user equipment on the WLAN AP side. .

The first WLAN AP protocol stack may include a user plane protocol stack, and may also include a control plane protocol stack. In the present invention, the user plane protocol stack transport layer uses a GTP-U or 802.3 protocol, and the control plane protocol stack transport layer is used in the present invention. The SCTP protocol uses the newly defined WLAP protocol at the application layer. The second WLAN AP protocol stack may use, for example, a protocol stack of existing wireless local area network communications, such as a WIFI protocol stack, such as may include a MAC layer, a PHY physical layer.

Finally, the configuration of the protocol stack in the user equipment is described:

The user equipment protocol stack may have a first user equipment protocol stack and a second user equipment protocol stack, where the first user equipment protocol stack is used to implement data processing for communication with the eNB on the user equipment side, the second user equipment protocol stack Data processing for implementing communication with the WLAN AP on the user equipment side.

On the eNB side, the first part of the downlink protocol data unit that is branched out for the first eNB protocol stack is called the first protocol data unit, and on the user equipment side, the first part of the uplink protocol data unit that is branched out for the first user equipment protocol stack is called Second protocol data unit. That is, the offloaded uplink data and the downlink data both become protocol data units, but the invention is not limited.

It is easy to know that when the scenario is eNB and AC direct connection or other scenarios, the protocol stack is also configured as described above, and a detailed description is omitted here.

It should be noted that the types of the devices and the connection manners described above are only examples, and the present invention is not limited thereto.

In this embodiment, the 3GPP access network entity and the non-3GPP access network entity respectively use the eNB and the WLAN AP as an example, and the GTP is adopted between the eNB and the WLAN AP. -U protocol as a data plane transmission protocol, and in this embodiment, a GTP-U tunnel is established between the eNB and the WLAN AP by using the first request message and the first response message, and the user equipment is established by the WLAN AP in the LTE RAN The association between the identity and the identity of the user equipment in the WLAN. Referring to Figure 14, the method includes:

Step 701: The eNB sends a first request message to the WLAN AP, where the first request message includes an identifier of the user equipment in the LTE RAN, a radio bearer of the user equipment in the LTE RAN, a priority of the user equipment in the LTE RAN, and an eNB. The first request message is used to request the WLAN AP to identify the virtual access point and establish a tunnel with the WLAN AP. The virtual access point is configured on the physical access point in the WLAN to which the WLAN AP belongs.

Specifically, the identifier of the user equipment in the WLAN may be a MAC address or an AID of the user equipment in the WLAN.

The tunnel end point allocated by the eNB may include the TEID and the transport address (which may be Ipv4 and/or Ipv6, may be statically specified or dynamically selected).

In this embodiment, when the eNB performs step 701, the tunnel end point allocated by the eNB is associated with the identifier of the user equipment in the LTE RAN, so that the association between the identifier of the user equipment in the LTE RAN and the tunnel can be obtained.

Further, before the step 701, the method may further include: sending configuration information to the user equipment, where the configuration information is used to indicate that the user equipment performs measurement on the WLAN where the user equipment is located; and receiving the measurement result sent by the user equipment, and determining whether the measurement result is based on the measurement result.

Step 702: The WLAN AP receives the first request message, and sends a first response message to the eNB, where the first response message includes an identifier of the virtual access point and a tunnel end point allocated by the WLAN AP.

The virtual access point is a logical entity existing in a physical access point. When one physical access point supports multiple virtual access points, each virtual access point is a wireless access point to the user equipment. AP), each virtual access point can only be associated with one user device at a time. The identifier of the virtual access point may be a basic service set identifier (English: Basic Service Set Identifier, BSSID for short) or a service set identifier (English: Service Set Identifier, for short: SSID, or may be written as an extended service set identifier ( English: Extended Service set, referred to as: ESSID)). It should be understood that the basic service set (English: Basic Service Set, BSS for short) is a basic component of the WLAN network, and is usually composed of one access point AP and multiple workstations (English: Station, abbreviated as STA). The Extended Service Set (English: Extended Service Set, es) is composed of multiple BSSs. Each BSS has a unique identifier (English: Identity, abbreviation: ID), that is, a BSS ID or a BSS identifier. Since the BSS usually has one access point AP, the BSS identifier is usually the identifier of the access point AP, and may be, for example, the MAC address of the AP.

Step 703: The eNB sends a second request message to the user equipment, where the second request message includes an identifier of the virtual access point, where the second request message is used to indicate that the user equipment accesses the virtual access point.

The second request message is used to indicate that the user equipment accesses the designated virtual access point. Specifically, the second request message may be sent by using an SCell Addition or a data radio bearer configuration carried by the RRC connection reconfiguration message, or may be sent by other newly defined messages.

Step 704: The user equipment performs authentication and access to the virtual access point according to the second request message, where the virtual access point is a virtual access point corresponding to the identifier of the virtual access point in the second request message.

In the embodiment of the present invention, an achievable authentication and access mode is as follows: The virtual access point corresponding to the identifier of the virtual access point is found and sent to the virtual access point. The manner in which the user equipment accesses the virtual access point may include performing authentication to the virtual access point, associating with the virtual access point, and completing authentication.

The identifier of the user equipment in the LTE RAN may be a CRNTI identifier, a TMSI, or a TEID.

After the user equipment accesses the virtual access point, the WLAN AP obtains the identifier of the user equipment corresponding to the identifier of the virtual access point in the WLAN.

In this embodiment, the identifier of the user equipment in the LTE RAN may be acquired by the first request message, and then the identifier of the LTE RAN and the identifier of the user equipment in the WLAN may be established by using the identifier of the virtual access point. connection relation.

The identifier of the user equipment in the LTE RAN is associated with the tunnel end point allocated by the eNB, and the tunnel end point allocated by the eNB is associated with the tunnel end point allocated by the WLAN AP, so that the identifier of the user equipment in the LTE RAN can be obtained, and the user equipment is in the WLAN. The identity of the tunnel, the tunnel endpoint assigned by the eNB, and the tunnel endpoint assigned by the WLAN AP are associated with each other.

Step 706: The WLAN AP sends the association between the identifier of the LTE RAN and the identifier of the user equipment in the WLAN (hereinafter referred to as the association relationship in the embodiment) to the eNB, so that the eNB can aggregate the multi-flow according to the association relationship. The data is processed.

Specifically, the WLAN AP may send the association relationship to the eNB by using an Xw interface, and the used message may be a new message type, such as an update message.

Optionally, the WLAN AP may also send the identifier of the user equipment in the WLAN to the eNB, and the eNB establishes an association between the identifier of the user equipment in the LTE RAN and the identifier of the user equipment in the WLAN.

Step 707: The user equipment sends a second response message to the eNB, where the second response message is used to indicate that the user equipment has accessed the virtual access point.

If the user equipment does not choose to perform service offloading due to user preferences, terminal configuration, or ANDSF access network discovery and selection function policies, the user equipment sends a failure message to the eNB. When the user equipment sends a failure message, the process does not perform steps 704 to 706.

The step 707 is an optional step. After the user equipment accesses the virtual access point, the second response message may not be sent.

Step 708: The eNB performs multi-stream aggregation data transmission with the user equipment via the virtual access point.

Specifically, when the downlink multi-stream aggregated data (downlink data) is sent by the eNB to the user equipment, step 708 includes:

Step 1: The eNB sends the multi-stream aggregated data to the WLAN AP. In step 2, the WLAN AP sends the multi-stream aggregated data to the user equipment through the virtual access point. Step 3: The multi-stream aggregation sent by the user equipment to the virtual access point The data is processed.

In the first step, the eNB determines, according to the association between the identifier of the user equipment in the LTE RAN and the tunnel, and the identifier of the user equipment in the LTE RAN, the tunnel used to transmit the data of the multi-stream aggregation, and uses the tunnel to transmit to the WLAN AP.

In the second step, the WLAN AP receives the multi-stream aggregated data sent by the eNB, determines the tunnel used for the transmission according to the multi-stream aggregated data, and determines the user equipment in the WLAN according to the association between the identifier of the user equipment in the WLAN and the tunnel. The identifier of the WLAN AP indicates the target user equipment by using the identifier of the user equipment in the WLAN to send the data of the multi-stream aggregation to the user equipment.

When the uplink multi-stream aggregated data (uplink data) is sent by the user equipment to the eNB, step 708 includes:

Step 1: The user equipment sends the multi-stream aggregated data to the virtual access point. In step 2, the WLAN AP sends the multi-stream aggregated data received by the virtual access point to the eNB. Step 3: The eNB processes the multi-stream aggregated data sent by the WLAN AP.

In the following implementation of the present invention, the eNB transmits a downlink data transmission process to the user equipment through the WLAN AP through the GTP-U tunnel:

As shown in FIG. 15, the protocol data unit between the eNB and the AP includes an 802.3 protocol frame, an IP header (including an eNB IP address and an AP IP address), a GTP header, a PDCP header, and an IP data packet, between the AP and the user equipment. The protocol data unit includes a PHY header, a MAC header, a PDCP header, and an IP packet. Specifically, the eNB adds a GTP header to the first protocol data unit of the PDCP layer of the first eNB protocol stack, and then adds an IP header. The source address in the IP header is the eNB IP address, and the destination address is the IP address of the AP. Then, the first protocol data unit to which the GTP and the IP header are added is passed through the L2 layer and the L1 layer of the second base station protocol stack, that is, the 802.3 protocol frame is added, and the source address in the 802.3 protocol frame is the MAC address of the eNB, and the destination address is the AP. The MAC address is transmitted to the L1 layer of the first WLAN AP protocol stack of the WLAN AP, and then processed by the L1 layer and the L2 layer of the first WLAN AP protocol stack, and the MAC address of the user equipment in the WLAN is mapped through the TEID in the GTP header. The address, thereby restoring the first protocol data unit, and handing it over to the second WLAN AP protocol stack for processing.

The second WLAN AP protocol stack adds a MAC header to the first protocol data unit to implement scheduling addressing, quality of service (QoS: QoS), and generates a MAC protocol data unit (English: MAC Protocol) The Data Unit (MPDU) is then transmitted to the PHY layer of the second user equipment protocol stack of the user equipment through the PHY layer of the second WLAN AP protocol stack.

After receiving the MPDU, the PHY layer of the second user equipment protocol stack of the user equipment sequentially deletes the MAC header and the PHY header through the MAC layer and the PHY layer of the second user equipment protocol stack to obtain the first protocol data unit. At the same time, according to the bearer information corresponding to the first protocol data unit in the MAC header, the PDCP entity corresponding to the radio bearer information in the PDCP layer of the first user equipment protocol stack is instructed to process the first protocol data unit.

The following describes the transmission process of the eNB to offload uplink data to the user equipment through the WLAN AP through the GTP-U tunnel in the implementation of the present invention:

The user equipment adds a MAC header to the second protocol data unit of the PDCP layer of the first user equipment protocol stack and generates an MPDU, and then transmits the PHY layer of the second WLAN AP protocol stack of the WLAN AP through the PHY layer of the second user equipment protocol stack.

After receiving the MPDU, the PHY layer of the second WLAN AP protocol stack of the WLAN AP deletes the PHY header and the MAC header through the MAC layer of the second WLAN AP protocol stack to obtain the second protocol data unit, and then the WLAN AP uses the second protocol. The data unit passes through the L2 layer and the L1 layer of the first WLAN AP protocol stack, adds an IP header, a GTP header, and an 802.3 protocol frame, and transmits to the L1 layer and the L2 layer of the second eNB protocol stack of the eNB. Then, the eNB acquires the bearer information corresponding to the second protocol data unit according to the TEID in the GTP header, and indicates that the PDCP layer in the first eNB protocol stack and the PDCP entity corresponding to the radio bearer information process the second protocol data unit.

In the foregoing data transmission process of the multi-stream aggregation, when the user equipment has at least one radio bearer, it is also necessary to consider mapping the radio bearer and the priority of the user equipment in the LTE RAN to the protocol data unit of the multi-stream aggregated data.

In the header, the priority information can be added to the priority field of the MAC header (such as the TID field).

In another embodiment of the embodiment of the present invention, the 3GPP access network entity and the 3GPP access network entity may also be an eNB and an AC, respectively, as shown in FIG.

The bearer information between the eNB and the AC may be the TEID of the GTP header. The domain corresponding, that is, the allocated TEID corresponds to the bearer; the priority information may also correspond to the TEID field of the GTP header, that is, the allocated TEID corresponds to the priority. The protocol data unit between the AC and the AP includes 802.3 protocol frames (including AC MAC and AP MAC), IP header, CAPWAP header, 802.3 protocol frame (including UE MAC and eNB MAC), and IP data packets between the AC and the AP. The bearer information may be directly added to the CAPWAP header (such as Reserved Reserved in the CAPWAP header, HLEN, RID, WBID, Wireless Specific Information, payload payload field, etc.) or 802.3 protocol frame (such as TCI domain); priority information It is also possible to directly add a priority field (such as a TCI field) of an 802.3 protocol frame. The protocol data unit between the AP and the user equipment includes a PHY header, a MAC header, a PDCP header, and an IP data packet. Between the AP and the user equipment, the bearer information may be added with a MAC header such as a Type reserved field in a Frame control field in the MAC header. In the extension field of the PDCP header, the priority information may be added to the priority field (such as the TID field) in the MAC header.

In this embodiment, the 3GPP access network entity and the non-3GPP access network entity respectively use an eNB and a WLAN AP as an example, and 802.3 is used between the eNB and the WLAN AP. The protocol is a data plane transmission protocol, and in this embodiment, the eNB establishes an association relationship between the identifier of the user equipment in the LTE RAN and the identifier of the user equipment in the WLAN. Referring to Figure 21, the method includes:

Step 1001: The eNB sends a first request message to the WLAN AP, where the first request message is used to request the identifier of the virtual access point from the WLAN AP, where the virtual access point is configured on the physical access point in the WLAN to which the WLAN AP belongs.

Step 1002: The WLAN AP receives the first request message, and sends a first response message to the eNB, where the first response message includes an identifier of the virtual access point.

The virtual access point is a logical entity existing in a physical access point. When one physical access point supports multiple virtual access points, each virtual access point is a wireless access point to the user equipment. AP), each virtual access point can only be associated with one user device at a time. The identifier of the virtual access point may be a BSSID or an SSID, or may be written as an ESSID. It should be understood that the BSS is a basic component of a WLAN network and is usually composed of one access point AP and multiple STAs. ESS is made up of multiple Composed of BSS. Each BSS has a unique ID, that is, a BSS ID or a BSS identifier. Since the BSS usually has one access point AP, the BSS identifier is usually the identifier of the access point AP, and may be, for example, the MAC address of the AP.

Step 1003: The eNB sends a second request message to the user equipment, where the second request message includes an identifier of the virtual access point, where the second request message is used to indicate that the user equipment accesses the virtual access point.

Step 1004: The user equipment performs authentication and access to the virtual access point according to the second request message, where the virtual access point is a virtual access point corresponding to the identifier of the virtual access point in the second request message.

Step 1005: The user equipment sends a second response message to the eNB, where the second corresponding message includes an identifier of the user equipment in the WLAN, and the second response message is used to indicate that the user equipment has accessed the virtual access point.

The identifier of the user equipment in the WLAN may be a MAC address or an AID of the user equipment in the WLAN.

If the user equipment does not choose to perform service offloading due to user preferences, terminal configuration, or ANDSF access network discovery and selection function policies, the user equipment sends a failure message to the eNB. When the user equipment sends a failure message, the process does not perform the foregoing steps 1004-1005.

Step 1006: The eNB establishes an association relationship between the identifier of the LTE RAN and the identifier of the user equipment in the WLAN, and obtains an association between the identifier of the user equipment in the WLAN and the identifier of the user equipment in the LTE RAN.

Specifically, in this embodiment, the eNB may obtain the identifier of the user equipment in the WLAN from the second response message, and associate the identifier with the identifier of the user equipment in the LTE RAN.

In other embodiments, the eNB also receives the identifier of the user equipment that is sent by the WLAN AP in the WLAN, and may also carry the identifier of the virtual access point when transmitting, so that the eNB can establish the user equipment. The association between the identity of the LTE RAN and the identity of the user equipment in the WLAN.

Step 1007: The eNB performs multi-stream aggregation data transmission with the user equipment via the virtual access point.

The specific implementation of the step 1007 is the same as the step 908 in the foregoing Embodiment 9, and details are not described herein again.
