The Implementation And The New Technology Application Of GSM Mobile Terminal

Currently more and more new technologies have been applied into GSM mobile phones, this article mainly focus on the realization and application dual-SIM card this technology into the low-end mobile phones. This paper based on the original single SIM card hardware platform foundation, and completed the design and implementation of dual-SIM card solution. The main function of this mobile phone is:dual-SIM card dual-standby single talk, bluetooth, camera, FM.This thesis introduced the detailed application and realization of dual-SIM into mobile phones. Firstly, this paper introduces the single chip platform based on Infineon hardware system structure, which let readers have a more in-depth understanding to the mobile phone system. Then this paper studied further the mobile phone dual-SIM card interface chipset and the software realization process. Meanwhile this paper described the detailed functions. Finally this thesis summarized the problems, analysis process and final solution in the process of testing and development. The text of the many methods is working experience summary, have very strong practicability, on subsequent products provide a valuable experience.
