Abstract

The invention discloses a dual card network searching optimization method, which is characterized in that one SIM card in a mobile phone searches the network firstly and records the network searching result; when sends out a network searching request, the other SIM card is accessed into the network by directly reading the record, thus reducing the network search of the dual card mobile phone once, thereby reducing the electric consumption of the battery and shortening the network searching time to a great extent.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a network finding optimization method for a single-chip dual-card dual-standby mobile phone. Background technique [0002] At present, users who use the Global System for Mobile Communications (Global System for Mobile; GSM) can only obtain network services after inserting a Subscriber Identification Module Card (SIM card for short) into a mobile phone. Through the SIM card, the user can become a registered user of the network and enjoy various services provided by the network. Most of the mobile phones on the market currently have a single SIM card, but many users have more than one SIM card and often need to change the SIM card It is quite inconvenient to use. [0003] Driven by technology, market and wireless mobile application business, the wireless mobile communication industry has developed rapidly, and mobile communication products have become a necessity for people's ...
