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.

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.
