摘要
鉴于WiFi信号的覆盖范围的日益扩大和智能终端设备的普遍应用,设计开发一种应用于Android移动设备的无线语音通信系统。语音信号通过WiFi无线网络传输。接入无线局域网内的Android系统终端用户可通过WiFi无线网络相互之间进行免费的全双工语音通话,也可以通过服务器上的VOIP接口发起和接收远程呼叫。同时实现了服务器对终端设备的控制和管理。该系统获得良好的通话质量,并具有较强的可扩展性。
In view of increasing expansion of area the WiFi signal covers and pervasive use of smart terminal devices,we design and develop a wireless audio communication system using in Android mobile devices.The audio signals are transmitted though WiFi wireless network.Users with Android system devices can make free full-duplex voice calls to each other through WiFi network when accessing to WLAN,and can also initiate and receive remote calls though a VOIP interface on the server,and simultaneously the control and management of the server on terminal devices are realised as well.The system is good in call quality and has quite high scalability.
