Method and system for simultaneously using plurality of networks based on Android system

Abstract

The invention provides a method and a system for simultaneously using a plurality of networks based on an Android system. The method comprises the following steps: pre-shielding a native mobile data network dialup driver positioned in an RIL (Radio Interface Layer) of the Android system; switching on a mobile data network connection according to an instruction, and modifying a value of a Flag file into a starting value; when the value of the Flag file is monitored to be the starting value, running a mobile network dialup program pre-installed on a Linux layer in order to acquire an IP (Internet Protocol) address of a current network; adding the IP address into a routing table; and establishing a Socket on an application layer according to the routing table in order to perform a mobile network connection. The customized mobile network dialup program is built in the Linux layer of the Android system. When a first instruction is received, the mobile data network connection is switched on, and the mobile network dialup program pre-installed in the Linux layer is directly run without any framework, so that a priority judgment mechanism of the framework can be avoided, and a mobile network and other network connection ways can be used simultaneously.

Description

technical field [0001] The present invention relates to the field of intelligent terminal equipment, in particular to a multi-network combined method and system based on an Android system. Background technique [0002] Android smartphones or tablets on the market usually use wifi to access the Internet or mobile data (including 3G, 4G, GPRS) connections. Wifi and mobile data connections can only be selected, and the default priority of wifi connections is higher. High, that is, when the mobile data service and wifi function are turned on at the same time, the Android system will judge and identify and give priority to using wifi to surf the Internet by default, and cannot make these two data links exist and use at the same time, the result is that it cannot be realized Some Android layer applications (such as web browsers) use wifi to connect to the Internet while some other applications also use mobile data traffic to access the Internet. [0003] Dial-up access based on P...

Problems solved by technology

Due to the strict design of the code structure of the Android framework layer, it is difficult to modify it, and the stability of the original Android system layer cannot be maintained after modification. It is a customized system and is usually inconvenient to modify
