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: A data packet processing method and apparatus is disclosed. According to the method, a storage apparatus disposed on a network side stores a correspondence between an identifier and data flow characteristic information. When configuring a policy for a data packet including a first identifier, a network-side device requests the storage apparatus for data flow characteristic information corresponding to the first identifier. A PCEF receives a data packet that is sent by UE, matches the data packet against the data flow characteristic information, and when the data packet matches the data flow characteristic information, executes a policy on the data packet according to policy information corresponding to the first identifier. According to the method provided in embodiments of the present disclosure, transmitting a considerable amount of data flow characteristic information on an interface of an SCEF is avoided, and load on the SCEF is relieved.

Abstract: In a data transmission method, a terminal device determines a first message, where the first message indicates that the terminal device is to move from a first network to a second network. The terminal device sends the first message to a first network device in the first network. The first network device is an access and mobility management function network element or an access network device.

Abstract: In a connection reactivation method, a connection of a PDU session established by user equipment on a N3GPP side is reactivated through communications via a 3GPP network. The user equipment accesses both the 3GPP and the N3GPP network and is originally in an idle state on the N3GPP network. An access and mobility management function entity receives a first message from a session management function entity to reactivate the PDU session connection of the user equipment. The access and mobility management function entity sends a second message to the user equipment via the 3GPP access network to instruct the user equipment to reactivate the connection of the PDU session.

Abstract: A data packet verification method and a device improve network security. The method includes: receiving a data packet of a terminal device, where the data packet carries a first token and a service identifier, and the service identifier is used to indicate a type of a service to which the data packet belongs; obtaining first input information based on the data packet, and generating a second token based on the first input information, where the first input information includes an identifier of the terminal device and the service identifier carried in the data packet; and sending the data packet when the first token is the same as the second token.

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.

Abstract: A network access control method and an apparatus are disclosed. The method includes controlling, by a first network device if determining that a terminal device already establishes a second data connection to a second network, the terminal device to stop establishment of a first data connection to a first network, or controlling the terminal device to end the second data connection, to smoothly establish a first data connection. In this way, it can be ensured that a data connection exists between the terminal device and one network, and it can be ensured that the terminal device can normally transmit data.
