摘要： Embodiments of this application provide a communication method and a communication apparatus. The method includes: An access network device sends first information, where the first information is used to trigger to buffer downlink data of a terminal in an inactive state in a core network element; and the access network device sends second information, where the second information indicates the terminal to enter the inactive state. According to the method provided in this application, a core network side can help an access network side buffer downlink data of a terminal in an inactive state, so that storage pressure of data buffering on the access network side can be relieved.

摘要： This application provides a communication method and apparatus, and may be applied to a 5GMS system. The method includes: An application function network element may indicate, based on obtained first information, a source end device, for example, a terminal device or an application server, to add identification information to different types of data in a service stream, so that each network element on a transmission path of the service stream collects statistics on and reports traffic characteristics of the different types of data in the service stream. In this way, a policy control network element in an MNO network may dynamically adjust transmission policies of different types of data in the service stream based on the traffic characteristic, to ensure high-rate real-time transmission and high-definition playing of the service stream, thereby improving user experience.

摘要： This application discloses a communications method and apparatus, and relates to the communications field, to resolve a problem that a terminal device can still receive downlink LADN data when moving out of an LADN SA. The method in this application includes: receiving, by a RAN node, a first message from an AMF node, where the first message includes specified area related information of a terminal device, and the specified area related information is used to indicate a specified area of the terminal device; and when the RAN node determines, based on the specified area related information and first location information of the terminal device, that the terminal device moves out of the specified area, sending, by the RAN node, the first location information or first indication information to the AMF node or a session management function SMF node, where the first indication information is used to indicate that the terminal device already moves out of the specified area. This application is applicable to a 5G communications procedure.

摘要： Embodiments of this application provide a communication method, including: when a terminal device is in an idle mode or an inactive mode, a first control plane functional entity obtains access network information of the terminal device, and the first control plane functional entity sends context information of the terminal device to an access network device corresponding to the access network information. Therefore, when the terminal device is in the idle mode or the inactive mode, in the embodiments of this application, the first control plane functional entity obtains the access network information of the terminal device, and pre-sends the context information of the terminal device to the access network device corresponding to the access network information. When the terminal device needs to transmit data, to be specific, the terminal device needs to be switched from the idle mode or the inactive mode to the connected mode, the terminal device does not need to wait for the process of transmitting the context information of the terminal device, thereby facilitating reducing a delay.
