Disclosed in an embodiment of the present invention are a communication method and device, and a computer readable storage medium, the method comprising: receiving data network identifier information from a session management function network element, the data network identifier information comprising an identifier of at least one data network supporting and serving first terminal equipment at a current position; under the condition that a first terminal equipment does not access a first data network, sending a first message to the session management function network element, the first message comprising an identifier of the first data network, the identifier of the at least one data network supporting and serving the first terminal equipment at the current position comprising the identifier of the first data network, and the first message being used for establishing a data path between a shunting node and a user plane function network element corresponding to the first data network. According to the embodiment of the invention, the data path between the shunting node and the user plane function network element corresponding to the data network is established, and the communication path between the terminal equipment and the data network can be shortened.
Description
technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a communication method, device, and computer-readable storage medium. Background technique [0002] In a fifth generation (5th generation, 5G) communication system, a terminal device may be connected to a data network (data network, DN) through a user plane function (user plane function, UPF). Which UPF and which DN an end device uses to communicate is determined during session establishment. After the session is established, since the location of the terminal device is not fixed, if the location of the terminal device changes, the terminal device still uses the UPF and DN during the session establishment process, which will cause the difference between the terminal device and the DN. The communication path between them is long. Contents of the invention [0003] The embodiment of the invention discloses a communication method, device and c...
