Problems solved by technology

[0003] At present, some solutions are used to achieve internal and external network communication. Among them, the patent document "Security Device for Isolating Terminals from Internal and External Networks of the System" with application number 200820183096.X discloses a terminal security device for isolating internal and external networks. The two front-end servers communicate through serial ports, and the internal network devices can access the public network by connecting to the intranet front-end server. Because this solution uses expensive servers, the cost is relatively high
[0004] To sum up, the prior art internal and external network communication devices have the disadvantage of high implementation cost; and currently there is no solution for directly requesting and obtaining geographical location information from the internal network to the external network

Abstract

The invention discloses a geographical position information acquisition method. The method comprises the following steps: internal network equipment is connected with an internal and external network communication device through a serial port line and an Ethernet interface of the internal and external network communication device is connected with an external network; the internal network equipment sends a geographical position request message to the internal and external network communication device and the internal and external network communication device packages an HTTP (hypertext transport protocol) request message according to request parameters in the geographical position request message and sends the HTTP request message to corresponding position service providing equipment of the external network; and the internal and external network communication device receives an HTTP response message of the position service providing equipment from the external network, then packages a geographical position response message according to the response contents in the HTTP response message and sends the geographical position response message to the internal network equipment. The invention also discloses an internal and external network communication device. The method and the device have the following beneficial effects: the internal network equipment can directly request and obtain the geographical position information for the external network through the internal and external network communication device.

Description

technical field [0001] The invention relates to the field of internal and external network communication of data communication technology, in particular to a method for acquiring geographical location information and an internal and external network communication device. Background technique [0002] In some private networks, all services or applications are inside the private network (intranet), but many applications need to use the location query service provided by the location service provider in the public network, so when using such services It must be able to access the public network, which brings security risks to the private network. Once the devices in the private network accessing the public network are compromised, the entire private network can be directly compromised. Therefore, it is necessary to provide a safe method for obtaining geographic location information and a communication device for internal and external networks. [0003] At present, some solutio...
