基于OMAP5912和SIP的无线IP电话终端

Wireless IP phone terminal based on OMAP5912 and SIP

以车载汽车电子多媒体视听系统为研发背景,探讨了在OMAP5912平台上采用SIP(会话发起协议)来实现基于CDMA的无线IP电话终端的设计。首先给出了无线IP电话终端的硬件设计方案,在分析了SIP和oSIP协议栈之后,给出了IP电话终端的程序设计框架。最后,结合所提出的方案,在OMAP5912平台及MontaV ista Linux嵌入式操作系统上实现了IP电话终端,并给出了测试结果,同时,与现有的一些移动终端的解决方案进行了比较。

The design of a CDMA based wireless IP Phone terminal using SIP （session initiation protocol） upon the OMAP5912 platform was discussed, under the background of a vehicle electronic multi-media video and audio system. The hardware designation plan of wireless IP phone terminal was firstly presented, and then the program architecture was also shown after analyzing SIP and oSIP stack. Finally, the IP phone terminal was implemented and the test result was presented, upon OMAP5912 platform and MontaVista Linux system embedded with the combination of the plan that was presented. Also, the plan itself was compared with other mobile terminals.
