Abstract
Various embodiments provide a session establishment method and system, and a device, to resolve a prior-art problem that NAS message transfer cannot be separated from session user plane establishment and application in some scenarios is limited. In those embodiment, under the establishment method, a first non-access stratum (NAS) message is sent by a terminal to a first access network device corresponding to a first access technology, where the first NAS message is used to request to establish a session. A second NAS message from the first access network device can be received by the terminal, where the second NAS message carries an identifier of a user plane function network element. A session establishment procedure can be initiated by the terminal between the terminal and the user plane function network element based on the identifier of the user plane function network element by using a second access technology.
