摘　　要：VoIP是一种新型的语音通信技术,由于其以Internet作为载体受到了广泛的关注。利用已有的WLAN网络实现无线的VoIP通话,可以提高网络资源的利用率并降低了通话成本。提出了一种基于SIP协议把VoIP和WLAN技术相融合的嵌入式无线终端方案,进行了硬件和软件设计,为系统开发提供了可行的实现途径。VoIP is a new type of voice communication technology, and attracts much attention because it utilizes Internet as transmitting messages carrier. The realization of wireless VolP call by using existed WLAN can improve the network using rate and reduce the communication cost. An embedded wireless terminal design scheme is introduced, which is a combination of VoIP and WLAN technology based on SIP. Both hardware and softvare design are made, and system development is provided with feasible realization method.
