201. the method comprises the steps that UE accesses a first network and obtains a first address which is distributed to the UE and used for transmitting service in the first network;

202. the UE accesses a second network and obtains a second address which is distributed to the UE and used for transmitting service in the second network, wherein the first network and the second network are networks of different systems;

For example, in the prior art, uplink and downlink data of the same service are transmitted on the same system. For example, the UE opens an internet web page, and both the web page data request (uplink) and the web page data (downlink) of the UE and the corresponding acknowledgement frame are transmitted on the LTE or WLAN side. The scheme of the embodiment of the invention ensures that the webpage data request (uplink) of the UE can be transmitted on the LTE side, the webpage data (downlink) can be transmitted on the WLAN side, and the confirmation frame (uplink) of the webpage data (downlink) can be transmitted on the LTE side.

Subsequently, the network side device can perform address conversion on the uplink data and the downlink data of the UE based on the binding record, and under an application scenario that the UE accesses two networks simultaneously, the network side device can assist in realizing transmission of the uplink data and the downlink data of the UE in different networks, thereby facilitating better balancing of transmission amount of each network and further facilitating improvement of service transmission performance of the network.

In the embodiment of the present invention, the access network element of the first network and the access network element of the second network may be separate devices, or may be integrated in the same physical device.

it is understood that there is no necessarily chronological order between steps 401 and 402.

403. The method comprises the steps that UE sends an address Binding request (Binding request) to a Packet data gateway (P-GW), wherein the address Binding request can carry a first address and a second address;

404. the P-GW receives the address Binding request, and the P-GW may record the Binding of the first address and the second address and may further feed back an address Binding response (Binding response) to the UE.
