摘要
结合Android平台的NDK集合,设计及开发了在Android平台上使用SIP协议的软件使之能通过SIP软交换服务器进行通话,并针对性地提出以太网数据包的过滤策略,完善了数据包解析模块,实现了SIP软交换系统的功能扩展。系统将C语言开发的模块全部改用跨平台的Java来编写,较传统的SIP软交换系统而言,其可移植性更强。
This research combines NDK sets of Android platform, designs and develops software using SIP agreement on the Android platform to make it communicate with SIP soft-switch server, pertinently proposes the filtering strategies of Ethernet data packet, improves the parsing module of data packet, and realizes function expansion of SIP soft-switch system. This system changes the module edited by C language into the module edited by Java of cross-platform, which is more portable compared with traditional SIP soft-switch system.
