Android手机中基带跟踪数据的导出功能设计

A Method to Export Baseband Tracing Data in Android System

本文主要基于现有Android手机系统框架设计了一种基带跟踪数据导出方案。对方案的总体框架、AP侧的软件流程、CP侧跟踪数据发送流程、串口通信机制的设计进行了详细说明,并给出了方案验证。在由三星公司Exynos 4412四核AP芯片和重邮信科公司C6310双模CP芯片组成的手机硬件系统上实现和测试了该方案。实验结果表明,该基带数据导出方案在实际产品中具有良好的可靠性和可行性。

This paper designs a method of base-band tracking data export program based on the framework of existing Android phone sys tern. It includes the general framework of the design, software workflow of the AP part, tracing data sending process of CP part and the design of port mechanism. It gives the program verification. Then it implements the method on the hardware system with Samsung Exy- nos 4412 Quad-core AP chip and Cqcyit company＇s C6310 dual-mode CP chip. The results show that the baseband data export program in the actual commercial products have good reliability and feasibility.
