Abstract: A communication method and a device, to implement service isolation of an Ethernet broadcast frame. In this method, when a terminal device initiates establishment of a session of an Ethernet type, a virtual local area network management function entity in a communications system may determine a virtual local area network identifier of a user group to which the terminal device belongs. In this way, a user plane function entity in the session of the terminal device may allocate a plurality of virtual ports to a virtual local area network whose identifier is the virtual local area network identifier, and broadcast the Ethernet broadcast frame on the plurality of virtual ports.

Abstract: The communication method and the communications apparatus may be applied to the internet of vehicles, for example, V2X, LTE-V, and V2V. The method includes: A first terminal apparatus determines a scaling factor based on a subcarrier spacing of a first time-frequency resource to be used to send first data and/or a quantity of slots occupied by the first time-frequency resource. The first data is to-be-sent data of the first terminal apparatus, and the first time-frequency resource occupies a single slot or a plurality of consecutive slots. Then, the first terminal apparatus determines, based on the scaling factor, a size of a transmission block carrying the first data, and sends the transmission block carrying the first data to a second terminal apparatus on the first time-frequency resource.

Abstract: The present application discloses a DCN processing method for a PLMN that is applied to a network sharing scenario. An access feedback message of a network side is received, and selection assistance information of a DCN and an identifier of a PLMN that serves UE are obtained from the access feedback message, so as to know a PLMN that is actually accessed by the UE. A correspondence between the selection assistance information of the DCN and the identifier of the PLMN that serves the UE is stored. When the UE moves to coverage of the PLMN, a requested DCN to be accessed can be directly determined according to the correspondence, and a RAN node is requested to access the determined DCN. Therefore, a redirection process is reduced, and resource overheads are reduced.

Abstract: Embodiments relate to the field of wireless communications technologies, and in particular, to a session context handling method, a network element, and a terminal device. A method includes: receiving, by a session management network element, a first message that is from a mobility management network element and that is used to request to establish a session for a terminal device, where the first message carries an identifier of a data network; obtaining, by the session management network element, capability information of the data network based on the identifier of the data network; and when the capability information of the data network is that the data network supports a non-IP session, generating, by the session management network element, a non-IP session context based on an Ethernet or unstructured session context of the terminal device.

Abstract: An access method and an apparatus are provided. After access of the terminal to the dedicated core network that is corresponding to the DCN indication information and that the terminal needs to access is rejected by the first PLMN, the terminal re-determines the second PLMN different from the first PLMN, so as to connect, by using the second PLMN, the terminal and the dedicated core network corresponding to the DCN indication information, so that the terminal can quickly access the dedicated core network. In this way, system resource utilization and user experience are improved.

Abstract: In a data reporting method, a user plane network element sends a first message to a first user plane network element. The first message includes first reporting information, and is for requesting the first user plane network element to report first data based on the first reporting information. The first reporting information includes first indication information or reporting time information. The first indication information is for the first user plane network element to determine whether the reporting of the first data is allowed to be delayed. The reporting time information indicates to the first user plane network element to determine time for reporting the first data. The user plane network element then receives the first data from the first user plane network element.
