System, User Equipment and Method for Implementing Multi-network Joint Transmission

摘要

A system, UE and method for implementing multi-network joint transmission are provided. The system includes: a core network and an access network; the access network includes: a 3GPP access network element and a WLAN access network element; the core network comprises: a 3GPP core network element. The 3GPP access network element is connected to the core network element through a network interface, connected to the WLAN access network element through a traffic offload interface, and connected to a UE through a 3GPP wireless interface; and is used for merging received uplink user data, also used for performing traffic offload on downlink user data, to offload part of the downlink user data to the WLAN access network element. The WLAN access network element is connected to the UE through a WLAN wireless interface, for transmitting uplink user data and downlink user data between the 3GPP access network element and the UE.
