Abstract: A paging method, a paging device, and system are described. A mobility management network element (MME) obtains location information of user equipment (UE) in a non-3rd Generation Partnership Project (3GPP) network, where the UE already accesses the non-3GPP network. The MME receives a downlink data notification message, where the downlink data notification message carries an identifier of the UE. The MME pages the UE according to the location information of the UE in the non-3GPP network. In some implementations, a paging range may be determined according to the location information of the UE in the non-3GPP network, and a paging message does not need to be sent to all base stations in a registration area of the UE.

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: Embodiments of the present invention provide a network name processing method and a mobility management network element. The network name processing method includes receiving a network name sent by a mobile switching center/visitor location register MSC/VLR. The received network name is processed. The mobility management information message is sent to a terminal and according to a processing result based on the processed received network name to enable the terminal to display the network name of the registered network of the terminal. According to the embodiments of the present invention, the terminal always display the network name of the registered network of the terminal, thereby ensuring consistency in the network name display of the terminal, and improving user experience.

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.
