Abstract: Embodiments of the present invention provide a traffic flow splitting method and apparatus. In a process of accessing a 3GPP network by UE, an eNB in the 3GPP network sends a first multiflow aggregation instruction to the UE, to instruct the UE to establish a first multiflow aggregation channel between the UE and the eNB via a non-3GPP network. The UE establishes the first multiflow aggregation channel. The first multiflow aggregation channel is used for transmitting a part of data in a downlink traffic flow for the UE, where the part of data is offloaded to the non-3GPP network for transmission, and other data in the downlink traffic flow is offloaded to a 3GPP channel for transmission. In the method, different data packets in a same traffic flow can be simultaneously transmitted in the 3GPP network and the non-3GPP network.

Abstract: An embodiment of the present invention provides an access method in a wireless communications network. Authentication and authorization functions of a 3GPP AAA server for a non-3GPP access network can be integrated into a mobility management network element. Therefore, after UE accesses the non-3GPP access network, a non-3GPP access gateway may select the mobility management network element that supports the authentication and authorization functions for the non-3GPP access network as a target mobility management network element, and request the target mobility management network element to perform authentication and authorization for the UE. After authentication and authorization are performed for the UE, the non-3GPP access gateway may select a P-GW for the UE, and set up a PDN connection between the non-3GPP access gateway and the selected P-GW for the UE.
