Method for recovering data parameters of communication module and electronic equipment

Abstract

The invention discloses a method for recovering data parameters of a communication module and electronic equipment. The method is applied to the electronic equipment, and includes receiving a request for recovering signal parameters of the communication module; invoking preliminarily stored signal parameters; transmitting a data write request to the communication module via a radio interface layer (RIL); writing the signal parameters into the communication module via the RIL so as to recover configuration of the signal parameters of the communication module when a write confirmation instruction transmitted by the communication module is received via the RIL. The method and the electronic equipment have the advantage that normal communication functions of the electronic equipment can be quickly recovered.

Description

technical field [0001] The invention relates to the technical field of communication, and more specifically relates to a data parameter restoration method of a communication module and electronic equipment. Background technique [0002] Currently, there are more and more electronic devices based on dual processors, such as mobile terminals such as mobile phones and PADs based on dual processors, and tablet computers based on dual processors. [0003] Taking a dual-processor-based mobile phone as an example, there are two built-in processors in the mobile phone, in which the operating system, user interface control and application programs are all executed on the application processor (AP, Application Processor), and the radio frequency of the mobile phone The communication control runs in another processor, which is called a baseband processor (BP, Baseband Processor). The AP in the mobile phone can exchange data with another processor BP, for example, the AP sends correspo...

AI Technical Summary

Problems solved by technology

However, when some signal parameters preset in the mobile phone communication module (parameters that affect mobile phone signals, such as radio frequency parameters) change, it may cause BP to fail to execute the control commands issued by the AP, and the status of the AP and BP cannot match. question

In many cases, certain abnormal operations of the user will cause configuration errors or abnormalities in the signal parameters in the communication module, which will cause the AP and BP states to fail to match, affecting the normal communication of the mobile phone
