Embodiment Construction

[0039] A gateway device distribution method in an LTE-VPN evolved system is applied to uplink transmission, and the LTE-VPN evolved system includes a gateway device and a VPN server connected to each other.

[0040] VPN virtual private network can be understood as a virtual enterprise internal dedicated line. It can establish a dedicated communication line between two or more intranets located in different places connected to the Internet through a special encrypted communication protocol. The function of a virtual private network is to establish a private network on a public network for encrypted communication. It is widely used in enterprise network. The VPN gateway realizes remote access by encrypting the data packet and converting the destination address of the data packet. There are many classification methods for VPN, mainly according to the protocol. VPN can be realized by server, hardware, software and other methods. VPN has cost Low, easy-to-use features.

Abstract

The invention provides a gateway device shunting method and system in an LTE-VPN evolution system. The LTE-VPN evolution system comprises a gateway device and a VPN server, which are connected with each other, for an uplink data packet, when a terminal access IP is the IP of the VPN server, core network message header information in the data packet is removed and the data packet is sent to the VPN server with the core network message header information removed, for a downlink data packet, when the core network message header information corresponding to the data packet exists, the inquired core network message header information is packed for the data packet, and the packaged data packet is sent to a base station. In the whole process, in the traditional LTE architecture, directional shunting VPN service is imported into the gateway device, the terminal data are loaded in a VPN tunnel and is guided to the VPN system in the gateway device, and the VPN service system provides Internet service and the like in order to effectively reduce the Internet core pressure.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for distributing traffic of gateway equipment and an LTE (LongTerm Evolution, long-term evolution)-VPN (Virtual Private Network, virtual private network) evolutionary system. Background technique [0002] In the field of LTE mobile communication technology, the mobile terminal is connected to the base station, the base station is connected to the gateway, the gateway is connected to the core network, and the core side is connected to the Internet. These links form a complete LTE communication system architecture. [0003] In terms of mobile terminals, with the development of smart phones, most of the Android and Apple series support the VPN function. In terms of the operator's core network, as customers' demand for traffic increases, the pressure on the operator's core network is also increasing, which affects the number of access terminals and ...
