Network telephone set and method for processing speech call in Internet

本发明描述了一种在互联网上处理语音呼叫的网络电话机和方法。经由未受管理的900MHz无绳电话频谱或其他分配给无线通信的无线连接提供了在IP连接设备，网络接口盒或机顶盒，和一个或多个无线手机之间的RF链路。在网络接口盒中的一个处理/控制组件运行所要求的IP协议以建立和管理呼叫的建立和拆除，将数字化的话音信号在IP和本地RF链路协议之间转换，并提供手机的RF基站功能。每个手机将包含RF链路的另一端。到电话手机的无线接口可以通过连在诸如混合光纤同轴网络的电缆网上的机顶盒。在使用一个RF链路以在一个诸如电话手机的电话设备和一个诸如机顶盒的电话手机之间传输压缩的话音/数据信息时，诸如互联网协议的协议可以用于保持到电缆网络的数字连接。 A system and method are described providing a wireless interface to an Internet Protocol (IP)/Internet telephony system. A wireless connection via the unregulated 900 MHz cordless phone spectrum or other spectrum allocated for wireless communications provides an RF link between an IP connection device, a network interface box or set-top box, and one or more wirelss handsets. A processing/control element in the network interface box runs the required IP protocols to establish and manage call set-up and teardown, translate the digital voice signal between IP and the local RF link protocol, and provide the RF base station function for the handset(s). Each handset would incorporate the other end of the RF link. The wireless interface to a telephone handset may be through a settop box that is tied into a cable network such as a hybrid coaxial cable network. A protocol such as the Internet Protocol may be used to maintain a digital connection into a cable network while using an RF link to transmit compressed voice/data information between a telephone device such as a telephone handset and an interface unit such as a settop box.
