Abstract: Embodiments of this application disclose a session handling method and a related device. The method includes: receiving, by a first AMF network element, a first message from a second AMF network element, where the first message includes information about a network slice corresponding to current sessions of a terminal; when determining that the first AMF network element does not support a network slice corresponding to a first session, sending, by the first AMF network element, a first notification message to the second AMF network element, where the first notification message notifies that the first AMF network element does not support the network slice corresponding to the first session; and releasing, by the second AMF network element, a network resource corresponding to the first session. A waste of network resources can be reduced by using this application.

Abstract: Embodiments of the present application relate to the field of computer technologies, and provide a service migration method, apparatus, and system. The method is performed by a target mobile edge platform, including: receiving a service migration request sent by a source mobile edge platform; obtaining a service endpoint corresponding to a service identifier; and sending a service migration response to the source mobile edge platform. In this way, a problem of migrating a service from the source mobile edge platform to the target mobile edge platform is resolved, and it can be ensured that after the service is migrated from the source mobile edge platform to the target mobile edge platform, a local mobile edge platform that subscribes to the service on the source mobile edge platform can continue to correctly use the service migrated to the target mobile edge platform.

Abstract: This application relates to the field of communications technologies. This application discloses a method, an apparatus, a network device, and a system for releasing an IP (Internet protocol) address, to resolve a problem that a time at which the IP address is released is not precise. The method includes: determining, by the first network device, that a PDU session anchor needs to be relocated from a first user plane function entity, where the first user plane function entity is the PDU session anchor of a first PDU session of a terminal; determining, by the first network device, that a first IP address of the terminal is no longer used, where the first IP address is an IP address used by the terminal in the first PDU session; and releasing, by the first network device, the first IP address.

Abstract: The present application relates to a data migration method and an apparatus, which are applied to a scenario in which a user plane gateway communicating with a terminal is changed from a source user plane gateway to a target user plane gateway. The target user plane gateway receives an address of the terminal from a control plane gateway, obtains an Ethernet data packet based on the address of the terminal, and sends the Ethernet data packet to an Ethernet interface, so that a switch obtains the Ethernet data packet through the Ethernet interface, and updates a MAC address table based on the Ethernet data packet. Thus, the switch updates the MAC address table in a timely manner, and the switch can send, through a correct port based on an updated MAC address table, downlink data to the terminal, to effectively prevent a loss of the downlink data.

Abstract: A communication method includes a first device that receives a first message for requesting a time synchronization service for a terminal device. The first device determines first information based on subscription information of the terminal device, and determines a third device configured to provide the time synchronization service, and sends the first information to the third device. The subscription information includes at least one of indication information, one or more types of time source, or one or more clock accuracies, the first information includes a first type and/or a first clock accuracy, the one or more types include the first type, and the one or more clock accuracies include the first clock accuracy.

Abstract: Embodiments of this application provide a multicast communication method that includes: receiving, by a user plane function network element, a multicast packet, where the multicast packet includes a multicast address; matching, by the user plane function network element, the multicast packet with a packet detection rule PDR on the user plane function network element; and if the multicast packet successfully matches a first PDR, and the first PDR indicates to carry on matching another PDR, carrying on, by the user plane function network element, matching the multicast packet with another PDR. Optionally, the another PDR is a PDR whose priority is not higher than that of the first PDR.

CPC classification number: H04L67/142
Abstract: A method for determining a service and session continuity (SSC) mode and an apparatus, where the method includes: determining, by a terminal device, a requested SSC mode; and sending a first request message to a first core network element, where the first request message is used to request to establish a first protocol data unit (PDU) session, and the first request message includes a session type of the first PDU session, the requested SSC mode, and first indication information. The first request message sent by the terminal device to the first core network element may carry the first indication information, used to indicate that the SSC mode requested by the terminal device is not allowed to be modified, to prevent a network-side network element from subsequently making an erroneous decision, for example, modifying the requested SSC mode to another SSC mode that is not supported by the terminal device.
