Abstract

A method, device and system for sending data to a user terminal are provided, wherein the method includes: receiving a downlink data message sent by a server; when the downlink data message includes the IP address of the user terminal, querying the routing table and The IP address of the LTE terminal corresponding to the IP address of the user terminal; sending the downlink data message to the LTE terminal according to the IP address of the LTE terminal, so as to forward the downlink data message to the user terminal through the LTE terminal. In the embodiment provided by the present invention, the LTE terminal sends the downlink data message to the user terminal, and realizes the logical matching between the IP address of the LTE terminal and the IP address of the user terminal according to the routing table configured on the network side, so that The server can quickly and directly access the user terminal connected to the LTE terminal, thereby improving the efficiency of the network communication system.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a method, device and system for sending data to a user terminal. Background technique [0002] In the prior art, customer premise equipment (Customer Premise Equipment, CPE) or data transfer unit (Data Transfer Unit, DTU) are commonly used LTE terminals. The basic functions of LTE terminals include user terminal access and user terminal service functions. LTE The terminal also has the function of forwarding data packets. For example, through WiFi or other wired connections, the WiFi user terminal or wired user terminal can access and receive the data packets provided by the server. [0003] In the existing technology, the user directly accesses the computer, camera and various application terminals connected to the CPE or DTU through the Evolved Packet Core (EPC) Gateway Interface (Server Gateway Interface, SGI) side server of the core network. This is bec...
