Document Type and Number:
WIPO Patent Application WO/2019/042184
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 the two terminals correspond to a same UPF entity. The method comprises: a 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 user plane function entity determines a downlink path corresponding to the second terminal according to information about the uplink path corresponding to the first terminal and the addressing information of the second terminal; and the user plane function entity sends the data packet to the second terminal through the downlink path corresponding to the second terminal.
