Abstract: This application provides example methods and example apparatuses for sending multicast data. One example method includes establishing, by a core network user plane network element, a plurality of data connections to a terminal. The core network user plane network element can then determine a first data connection, where the plurality of data connections include the first data connection. The core network user plane network element can then receive multicast data sent to the terminal. The core network user plane network element can then send the multicast data to an access network element through the first data connection.

Abstract: This application provides a method for identifying a terminal device and a communications apparatus. A core network element obtains classification information for classifying a terminal device, and then determines, based on the classification information and a parameter of a first terminal device, a type of the first terminal device, to identify the first terminal device. In this process, the core network element identifies the first terminal device in a supervision area by using the classification information and the parameter of the first terminal device, to identify a terminal device that is not registered in a supervision system, thereby improving security of the terminal device.

Abstract: A method for authorizing a local service and a related device are disclosed. The method includes: In a roaming scenario, when there is no one-to-one roaming agreement between a service provider of a local network and a home operator, if UE accesses a home network, a home network device may authorize a local service based on subscription data of the UE and local service information of the local network when the UE is authorized to access the home network and if the service provider and the home operator are in a same roaming consortium, so that the UE can use a service of a visited location, to reduce load of the home network and improve network resource utilization.

Abstract: Embodiments of the present invention relate to field of communications technologies, and provide a mobility management method that can effectively ensure normal communication between user equipment and a base station without using an anchor device, and ensure service continuity between the user equipment and a communication peer. A specific solution is as follows: User equipment establishes a first substream with a communication peer; when the user equipment moves from a first base station to a second base station, and a second gateway and a first gateway are not the same gateway, the user equipment obtains a second IP address; after obtaining the second IP address, the user equipment establishes a second substream with the communication peer; after the second substream is established, the communication peer removes the first substream; and after the first substream is removed, the first gateway releases a network resource occupied for transmitting the first substream.

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: 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.
