Abstract: Example authentication methods and apparatus are described. One example method includes receiving access authentication information by an access network element from a terminal device. The access network element generates a first message based on the access authentication information, where the first message includes the access authentication information. The access network element sends the first message to an access management network element, and receives a first response message from the access management network element in response to the first message. The first response message includes response information of the access authentication information. The access network element sends the response information of the access authentication information to the terminal device based on the first response message.

Abstract: The present disclosure discloses a method and an apparatus for distinguishing an access network. The method is applied to a multi-access network architecture. In the multi-access network architecture, user equipment accesses a base station by using at least a first access network and a second access network. The method includes: sending, by the base station, a data feature set to a core network device after transmission of user plane data begins, where the data feature set includes an access network identifier corresponding to the user plane data and attribute information of the user plane data. The present disclosure is applied to a process in which the user equipment transmits data with the core network device by using a plurality of access networks.

Abstract: The present disclosure describes a network status information transfer method. In one example method, a first message, transmitted by a third-party server to a user equipment (UE), is received by the UE. The first message comprises an identifier, associated with a trusted wireless local area networks (WLAN) network (TWAN), and first indication information indicating that a packet data network gateway (PGW) is overloaded. If the UE has added the identifier associated with the TWAN to a blacklist, the identifier associated with the TWAN is deleted, by the UE, from the blacklist in response to receiving the first message.

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: The present disclosure provides an offloading policy negotiation method and apparatus, so as to resolve problems in the prior art that a method for initiating data flow switching by UE has low applicability, and that a network side cannot control and manage the UE, and that user experience is reduced. The method includes: sending, by a first device, an offloading policy to a second device, where the offloading policy includes a default access indication and a routing rule; and receiving and storing, by the first device, an acknowledged offloading policy returned for the offloading policy by the second device, and transmitting a data flow based on the acknowledged offloading policy.
