Abstract:
Embodiments of this application relate to a method for controlling service flow transmission. One example method includes: a session management network element obtains a first TMBR of a service flow transmitted in a session by using a first access technology and a guaranteed bandwidth of a first GBR service flow, where the TMBR indicates a TMBR of service flows transmitted in the session by using the first access technology. The session management network element sends first information to a data plane network element, where the first information is used by the data plane network element to determine one or more of the following information of the session: a first AMBR, a second AMBR corresponding to the first access technology, and a second TMBR. A second AMBR indicates an AMBR of a non-GBR service flow transmitted in the session by using the first access technology.
Abstract:
Connection processing methods in a multi-access scenario and apparatus are described. One example method performed by a mobility management functional entity includes receiving a first transmission message sent by an access network device. The first transmission message includes a registration request message, and the registration request message includes first multi-access indication information and identification information. It is determined, based on the first multi-access indication information and the identification information, that the user equipment has registered with a first communications network and has initiated registration with a second communications network. A procedure of registering the user equipment with the second communications network is performed. In the embodiments of the present disclosure, multi-access registration of the user equipment in the first communications network and the second communications network can be implemented.

Embodiments of the present invention provide a method for accessing a communications network by a terminal, an apparatus, and a communications system, relate to the communications field, and can effectively reduce a resource waste on a network side that is caused when WLCP is triggered by a malicious application on a terminal. A first message sent by a second device is received, where the first message includes a second message and an authentication parameter, the authentication parameter is a token or a User Datagram Protocol UDP port number, and the second message includes the encrypted authentication parameter; or the first message includes a second message, and the second message includes an encrypted authentication parameter; or the first message includes a second message and an authentication parameter; and the second message is sent to a terminal.
Abstract:
Embodiments of this disclosure provide a communication method and apparatus. The method includes: A first data management network element in a first network obtains identification information of a terminal device connected to an access gateway in a second network. The first data management network element obtains, based on the identification information, an access parameter of the terminal device from a second data management network element corresponding to the terminal device in the second network. The first data management network element obtains subscription data of the terminal device based on the access parameter. The first data management network element sends the subscription data of the terminal device to the access gateway.
