Method for quickly switching network system on mobile platform

Abstract

The invention relates to a method for quickly switching a network system on a mobile platform. The method comprises the following steps: storing a baseband module code library of different network systems into a mobile device; reading baseband library information from a system starting script by an RILD process; receiving reported notice by a baseband information fusion library after the modules of different systems are physically uplinked to the system, thereby obtaining Modem ID, Vendor ID and Product ID of each module; matching the three IDs by the baseband information fusion library in an own list and judging if needing to switch the network system; and extracting parameters and filling into a baseband abstract model by the baseband information fusion library and starting a model switching unit, thereby finishing the switching of the network system. The invention provides a method for realizing the quick switching of the network system on the mobile platform.

Description

【Technical field】 [0001] The invention relates to the technical field of wireless communication networks, in particular to a method for quickly switching network standards on a mobile platform. 【Background technique】 [0002] At present, the mobile platform needs to support various types of GSM modules and various 3G network standards, and the AT commands and communication processes used for communication between mobile devices and different modules are different. If there are two or more groups of modules of different standards on the mobile platform, there is a need to switch between different standards. It is necessary to add the corresponding library files, and query the module information according to the AT interaction results; then according to the information, different modules import different baseband management libraries, which takes up a lot of memory, and consumes CPU resources during the process of switching library files, and the switching time is long. Diffe...

[0003] Chinese invention patent 201010206662.6 discloses a method for automatically adapting wireless modules of different network standards. This method transfers the shared library paths corresponding to the network standards supported by various wireless modules into the RILD process. A baseband Vendor library, and before interacting with the baseband, you must first use a shared library, and then load a specific target baseband library. This process consumes time and memory
