Document Type and Number:
WIPO Patent Application WO/2019/042182
Kind Code:
A1
Abstract:
Embodiments of the present application provide a data transmission method, device and system, which allow two terminals to locally interact with each other when different UPF entities provide services to the two terminals. The method comprises: a first user plane function entity receives a data packet from a first terminal through an uplink path corresponding to the first terminal, the data packet carrying addressing information of a second terminal; the first user plane function entity determines path information of a second user plane function entity according to information about the uplink path corresponding to the first terminal and the addressing information of the second terminal; and the first user plane function entity sends a data packet to the second user plane function entity according to the path information of the second user plane function entity, and the second user plane function entity sends the data packet to the second terminal through a downlink path corresponding to the second terminal.
