Abstract: A group communications method and system, and a device are provided. The method includes: when a first terminal initiates access to a local area network group, obtaining, by a group management function network element, an identifier of a first user plane network element to be accessed by the first terminal, context information of the local area network group, and a first session port identifier; creating, for the local area network group, a rule group applied to a first session port, and creating or updating, for the local area network group based on the context information, a local area network group forwarding action rule (FAR) applied to the first user plane network element; and sending a first message to a session management network element, for configuring the rule group on the first session port, and configuring the local area network group FAR on the first user plane network element.

Abstract: A session handling method and apparatus, where the method includes: initiating, by a terminal, an application (APP); determining a session type of a packet data unit (PDU) session based on the APP; and sending a first message to an access and mobility management function (AMF) entity, where the first message includes the session type, and the first message is used to request to establish the PDU session of the session type. In the method, a network side can establish the PDU session of the corresponding type based on the session type of the PDU session that is sent by the terminal, in order to establish the PDU session of the correct type for the terminal.

Abstract: A synchronization method and an apparatus are provided to meet a time precision requirement of an industrial factory in a scenario in which a mobile network is connected to an Ethernet network. In an embodiment, a first device determines seventh timestamp information by using timestamp information of receiving and sending packets in a mobile network, so that a second device calculates a time offset between the first device and the second device based on the seventh timestamp information and time points of receiving and sending packets in an Ethernet network, to perform time synchronization. In the method, impact of a transmission delay between the first device and the second device can be avoided, so that a time precision requirement of an industrial factory can be met in a scenario in which the mobile network is connected to the Ethernet network.

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 present disclosure relates to a QoS guarantee method. In one example method, a control plane gateway obtains a QoS parameter. The QoS parameter comprises an allocation/retention priority (ARP) and a QoS class identifier (QCI). The control plane gateway maps the QoS parameter to QoS guarantee information. The QoS guarantee information comprises a differentiated services code point (DSCP) parameter. The control plane gateway sends the QoS guarantee information to a user plane gateway. The QoS guarantee information is to be used by the user plane gateway for QoS marking.
