System and method for cleaning invalid contact persons of mobile phone

Abstract

The method discloses a system and a method for cleaning invalid contact persons of a mobile phone. The method includes the following steps: A, a central processing unit (CPU) sends out a contact person backup instruction and an invalid contact person cleaning instruction to a microprocessor; B, the microprocessor reads a contact person communication log in a communication log module according to the contact person backup instruction and the invalid contact person cleaning instruction and obtains information of the invalid contact persons; and C, the CPU obtains the information of the invalid contact persons and deletes the information of the invalid contact persons correspondingly. Through timed generation of invalid contact person cleaning instructions, all the contact person information is backed up to a cloud server correspondingly, the communication log in a set time of the contact persons of the mobile phone is analyzed through the microprocessor, contact persons without communications or with little communication are obtained and deleted correspondingly. The system and the method achieve automatic cleaning of the invalid contact persons of the mobile phone, and promote seeking and maintenance efficiency of contact persons of the mobile phone and operating efficiency of a mobile phone system.
