Abstract:
Embodiments provide a method, which can implement establishment of an network function virtualization (NFV) network service link. The method includes obtaining, by a first communications unit, a service link rule, where the service link rule is used to indicate service processing that needs to be performed. The method also includes obtaining, according to the service link rule, information about a service link through which a service route passes, where the information about the service link is used to indicate information about a virtualized network function (VNF) through which the service route passes, and the VNF is configured for the service processing; and sending a route and resource configuration request message, where the route and resource configuration request message carries the information about the service link, to request to perform, according to the information about the service link, route and resource configuration for the VNF included in the service link.
Abstract:
This application provides a method for controlling disorder of downlink data and an apparatus thereof. The method includes: A control plane network element determines to switch from a first user plane device to a second user plane device, and sends indication information to the second user plane device. The second user plane device buffers, according to the received indication information, downlink data received from a session anchor, and sends the buffered downlink data after reception of an end marker from the first user plane device.
Abstract:
This application discloses a time synchronization fault processing method, apparatus, and system, and belongs to the communication field. The method includes: When time of a first translator in a first network is not synchronized with a clock source in the first network, the first translator stops communicating time information with at least one other translator in the first network than the first translator, where the time information is used for obtaining time synchronized with a clock source in a second network.
Abstract:
The present disclosure relates to a slice-based communications method. In one example method, an access and mobility management function (AMF) node sends a first request message to a network slice selection function (NSSF) node. The AMF node receives a response message from the NSSF node. The AMF node obtains, based on the response message, allowed network slice selection assistance information (NSSAI).
Abstract:
A network slice selection method and apparatus are disclosed. The method includes: receiving, by a first SSF device of a VPLMN, a first service request message; obtaining, by the first SSF device, roaming information of UE according to the first service request message; selecting, by the first SSF device, a first network slice instance in the VPLMN for the UE based on the roaming information of the UE.
Abstract:
A communication method, device, and medium are provided, the method including determining, by a terminal device, whether the terminal device supports at least one of a time sensitive networking (TSN) service, a packet data unit (PDU) session corresponding to a TSN service needs to be established, a currently established PDU session needs to carry a TSN stream, or an established PDU session needs to carry a TSN stream, and sending, by the terminal device, port information of the terminal device to a session management network element, where the port information of the terminal device includes a port identifier of the terminal device, and further includes information about a transmission delay between a port of the terminal device and an external neighbor node.
Abstract:
A communication method, including: receiving, by an access and mobility management function network element in a first public land mobile network, a registration request message from a terminal device; and when determining that a first condition is met, sending configured network slice selection assistance information of the first public land mobile network to the terminal device. The first condition includes either of the following: the registration request message is an initial registration request message, or the registration request message is sent after the terminal device moves from a second public land mobile network to the first public land mobile network.

Abstract:
Embodiments provide a method, which can implement establishment of a network function virtualization (NFV) network service chain. The method includes obtaining, by a first communications unit, a service chain rule, where the service chain rule is used to indicate service processing that needs to be performed. The method also includes obtaining, according to the service chain rule, information about a service chain through which a service route passes, where the information about the service chain is used to indicate information about a virtualized network function (VNF) through which the service route passes, and the VNF is configured for the service processing; and sending a route and resource configuration request message, where the route and resource configuration request message carries the information about the service chain, to request to perform, according to the information about the service chain, route and resource configuration for the VNF included in the service chain.
