Abstract

This disclosure discloses a method of sending a small router package from the mobile device client to the destination server before any new net connections are created. The router package records the IP address that the client hopped to. After the package reaches the destination, it is sent back to the mobile device client. It can help to save the network flow for mobile applications.

An accurate method to detect the network accessing mode for mobile devices

The mobile network data flow usage (e.g. GPRS / 3G / LTE, etc) of mobile devices is expensive for most people today. Many solutions are proposed to save the network flow for mobile applications. For example, when the mobile device is accessing Internet via network flow instead of WiFi, the applications will load unnecessary contents as few as possible, such as images, videos, and advertisements.

The premise of these flow saving solutions is to detect the network accessing mode accurately. However, current detecting method is not accurate enough in the following scenario:

Mobile device A is accessing the Internet via mobile network flow.

Mobile device A opens a personal hotspot for mobile device B.

Mobile device B can access the Internet by connecting to the hotspot of mobile device A.

In the above scenario, mobile device B is detected as accessing the Internet via WIFI and turns off all the network saving solutions. As a result, the network flow of mobile device A is wasted unnecessarily.

The disclosure proposed a method of sending a small router package from the mobile device client to the destination server before any new net connections are created. The router package records the IP address that the client hopped to. After the package reaches the destination, it is sent back to the mobile device client.

Each mobile device has a database storing all the IP addresses of the network carriers. If the hopped IP address in the router package is included in the database, it indicates that the mobile device client is connecting to a mobile d...
