题（中、英文）目基于 MTK 平台通话管理软件的设计与实现Design and Implementation of Call Management SoftwareBased on MTK Platform作 者 姓 名XXX提 交 论 文 日 期二〇 XX 年三月工 程 领 域摘 要本文以 MTK 手机开发平台为基础，简述了 MTK 平台中使用的 Nucleus 嵌入式操作系统，分析了 MTK 平台的软件架构，详细说明了 MTK 中的任务处理和消息管理机制。基于以上理论基础，对通话管理模块软件进行分析，详细分析了其中的 AT模块，讨论了 MTK 平台中 AT 命令的类型和格式，分析了通话管理模块中 AT 命令的收发格式。根据对通话管理模块软件的分析和 AT 命令收发格式的讨论，设计出底层 AT 命令的发送和响应过程，完成了通话管理软件中 AT 模块的设计。然后根据实际需求，在原方案的基础上，针对 AT 模块设计的缺陷提出了改进方案。利用扩展 AT 命令的实现原理，完善了对 AT 模块软件的设计，并最终实现了通话管理的主要功能。最后，设计测试用例，对完成的功能进行测试和验证。关键词： MTK 手机 通话管理 AT命令 AbstactThis thesis is based on the MTK mobile phones development platform. It briefly describes Nucleus operating system used in MTK platform, analyzes the framework of MTK platform, and focuses on the task processing and the mechanism of message management in MTK.Based on the above theory, this thesis analyzes the call management software and it’s AT module, studies the types and formats of AT commands, and expounds the sending and receiving formats of AT commands used in the call management. According to the analysis of call management software and the study of AT commands’ sending and receiving formats, this paper schemes out the sending and responding processes of AT commands and completes the design of AT module in the call management. According to the actual demands and on the basis of the original program, it puts forward the improvement. By using the realization principles of the expanded AT commands, it perf...
