Abstract: A method and an apparatus for initiating user plane path re-establishment and a communications system are disclosed. The method includes: determining, by a session management function entity based on first location information of a terminal device, a session service area to which a current session of the terminal device belongs; and after receiving second location information of the terminal device sent by a mobility management function entity, if determining that the second location information is not within the session service area, instructing the terminal device to initiate a re-establishment procedure for the current session or initiate a handover procedure. Due to introduction of the session service area, when the terminal device moves back and forth at edges of service areas of two adjacent user plane function entities, a ping-pong effect caused by frequent handover between the two user plane function entities is avoided, and user experience is improved.

Abstract: The present disclosure provides a method, device, and system for processing migration between dedicated core networks. The method includes: when a subscribed usage type of UE changes, obtaining, by a mobility management network element, the subscribed usage type of the UE; if dedicated core network assistance information of the UE does not match a dedicated core network served by the mobility management network element, sending a request message to the UE; and sending, to a serving base station of the UE, the dedicated core network assistance information in a radio resource control (RRC) connection establishment request message triggered by the access request message, so that the base station selects a dedicated core network corresponding to the dedicated core network assistance information for the UE.

Abstract: The present invention relates to the communications field, and in particular, to a message exchange method, a device, and a system. The method may include: receiving, by a core network device, a message, where the message carries a message identifier; obtaining, by the core network device, a service rule set, where a service rule in the service rule set includes the message identifier and a corresponding network function module identifier; determining, by the core network device, a corresponding target network function module identifier in the service rule set; and sending the message to a network function module of the corresponding target network function module identifier. The service rule in the service rule set may be changed.

Abstract: This application provides an indication information transmission method and a related apparatus. The method includes: An intermediate session management network element sends third indication information to a target user plane network element based on second indication information from a session management network element, so that the target user plane network element buffers an uplink packet based on the third indication information. When learning that handover to a target application network element has been completed, the session management network element may send fourth indication information to the intermediate session management network element, so that the intermediate session management network element sends fifth indication information to the target user plane network element based on the fourth indication information, and the target user plane network element forwards the uplink packet based on the fifth indication information.

Abstract: Example communication methods and apparatus are described. One example method includes determining a first encapsulation identifier corresponding to an Ethernet session by a control plane network element and sending the first encapsulation identifier corresponding to the Ethernet session to a user plane network element, where the first encapsulation identifier is used to instruct the user plane network element to process a data packet corresponding to the Ethernet session based on the first encapsulation identifier. The terminal device determines the first encapsulation identifier corresponding to the Ethernet session and encapsulates an uplink data packet based on the first encapsulation identifier, where the uplink data packet is a data packet triggered by an application program bound to the Ethernet session. The encapsulated data packet is mapped to the Ethernet session corresponding to the first encapsulation identifier for transmission based on the first encapsulation identifier.
