Embodiment 1

[0155] Based on the method of offloading from MeNB to SeNB, refer to Figure 7 As shown, Embodiment 1 of the present invention provides a method for establishing a path in which the eNB directly distributes traffic to the WLAN, which is applied on the base station side, and the specific process is as follows:

[0156] Step 700: After determining that a UE is connected to a designated WLAN network, the base station sends a request message to the WLAN network, where the request message carries at least the first MAC address of the UE.

[0157] Further, in the preprocessing stage, the base station receives a radio resource control (Radio Resource Control, RRC) message sent by the UE, and the RRC message carries the first MAC address of the UE; then the base station sends the UE's first MAC address to save.

[0158] For example, the UE can send its MAC address to the eNB by carrying its own MAC address in the RRC connection reconfiguration complete message (for details, refer to ...

Embodiment 2

[0181] In the second embodiment, the GTP protocol is used between the eNB and the WLAN network. Specifically, the process of establishing and transferring a path between an eNB and a WLAN network is as follows: Figure 9 As shown, the specific process is as follows:

[0182] Step 1: The eNB sends a bearer creation request message to the designated WLAN network, and the parameters in the bearer creation request message include MAC address 1 (that is, the initial MAC address of the UE) and the TEID allocated by the eNB for the user plane.

[0183] Step 2: The WLAN network allocates a bearer ID and a user plane TEID, and then returns a bearer creation reply message to the eNB. The parameters in the bearer creation reply message include the bearer ID and user plane TEID allocated by the WLAN network.

[0184] Step3: The eNB sends a path switching confirmation message to the UE, notifying the UE that the path from the eNB to the WLAN network is successfully established.

Embodiment 3

[0202] In the third embodiment, data is transmitted between the eNB and the WLAN network using layer 2 forwarding. Specifically, the process of establishing and transferring a path between an eNB and a WLAN network is as follows: Figure 10 As shown, the specific process is as follows:

[0203] Step1: The eNB sends a path establishment request message to the designated WLAN network, and the parameters in the path establishment request message include MAC address 1, which is the initial MAC address of the UE;

[0204] Step2: The WLAN network assigns a MAC address for transmitting the bearer data, that is, MAC address 2. The MAC address can be the MAC address of the GW in the WLAN network, and then returns a path establishment reply message to the eNB. The path establishment reply message contains the Parameters include MAC address 2;

[0205] Step3: The eNB sends a path switching confirmation message to the UE, notifying the UE that the path from the eNB to the WLAN network i...

Abstract

The invention discloses a data distribution path establishment method and device. The method and the device are used for solving the problem that an eNB cannot distribute part of traffic to a WLAN (Wireless Local Area Network) network. The method comprises the steps that a base station sends a request message to the WLAN network after determining that a piece of user equipment UE is connected with the appointed WLAN network; the base station receives a reply message returned by the WLAN network for the request message; and the base station sends a path switch acknowledgement message to the UE and informs the UE that a path distributed from the base station to the WLAN network is established successfully. In this way, the part of traffic transmitted through the base station can be distributed to the WLAN access network, and the wireless utilization rate of a 3GPP (Third Generation Partnership Project) access network is improved.

Description

technical field [0001] The present invention relates to the field of wireless technology, in particular to a method and device for establishing a path for data distribution. Background technique [0002] In the communication field, in order to improve the capacity and coverage of hotspots, in addition to densely deploying macro cells, another method that can be considered is to improve local throughput performance through densely deploying micro cells. However, in such a heterogeneous network scenario, there will be many problems. For example, due to the different transmission power of different base stations, it will cause power imbalance; especially in the case of co-frequency deployment, it will cause great interference to users at the edge of the cell, and the heterogeneous network deployment brings Interference affects handover performance, especially in the case of co-frequency deployment. On the other hand, the increase in the number of network nodes will increase t...
