Android-based double-network-card concurrence implementation method

Abstract

The invention discloses an android-based double-network-card concurrence implementation method. The method includes the steps that an application layer invokes and enables a mobile data function and a WIFI function to start a mobile network and a WIFI network; after connection of a new network is established, whether two default networks are activated or not is judged; if yes, the newly connected network and network state information of the new network are reserved, the new network and an original network coexist, and the process is ended; otherwise, whether a network transition wake lock variable is in a held state is judged, if yes, a time delay is set to close a screen, and otherwise, a default network variable is updated and activated to achieve network connection, the type of a running network is reset, and other variables are updated; a teardown request is set to be 'no', and network settings are updated; settings of a route, settings of a domain name system, settings of a network interface and link attributes are updated; a newly connected network is switched to, a broadcast message is sent to a network state service, and the network state service is notified that the name of the network interface is changed.

Description

Technical field [0001] This application relates to the field of mobile communication technology, and in particular to an implementation method for coexistence of dual network cards based on an Android system. Background technique [0002] Android is a free and open source operating system based on Linux, mainly used in mobile devices, such as smart phones and tablets. Most existing mobile devices have multiple network cards, such as a WIFI network card that accesses the Internet through a local area wireless network (WIFI) and a 3g / LTE network card that accesses the Internet through a mobile communication network. [0003] Since WIFI networks can be used for free, and 3g / LTE networks are usually billed according to traffic, the existing Android system networking strategy is usually WIFI priority, and only one network interface is allowed to communicate at the same time. Specifically, when the WIFI network is turned on, the system will turn off the 3G network by default or when the...

AI Technical Summary

Problems solved by technology

[0005] 1. Many companies or organizations such as banks, taxation, etc. have their own internal private network (WIFI). In daily work, they often encounter the problem of accessing the internal and external networks at the same time, such as working on the internal network, external network (3g / LTE) to check information, or exchange information with other people;

[0006] 2. When the user's wifi signal is very poor or weak, the internet cannot be accessed, and the system will not automatically switch to the 3g / LTE network to access the internet;

[0007] 3. When the user has special needs, the data service is divided into multiple interfaces according to the service type, and multi-network card communication is required at this time;
