摘要： A method and apparatus for configuring connectivity at a hub having a plurality of subscriber lines from a plurality of subscriber premises and a plurality of feeder lines from a central office. The hub provides connectivity between the plurality of subscriber premises and the central office. The method and apparatus include categorizing the plurality of subscriber lines into a plurality of groups based on penetration rates and chum rates of the plurality subscriber lines. Each group of subscriber lines are connected to feeder lines based on the penetration and chum rates for POTS and/or DSL services. Subscriber line groups with high penetration rates and high/low chum rates are coupled directly to feeder lines. Subscriber line groups with low penetration rates and high/low chum rates are terminated at the hub. Subscriber lines with an intermediate penetration rate are candidates for being connected to the feeder lines via an automatic switch.

摘要： A method and apparatus are provided for a gateway which interconnects public safety wireless networks and commercial wireless networks that support push-to-talk group calls. The gateway translates Real Time Protocol (RTP), Session Invitation Protocol (SIP), and Talk Burst Control Protocol (TBCP)/Real Time Control Protocol (RTCP) messages received from the commercial wireless network and RTP and SIP messages received from the public safety wireless network into a format of the receiving network. The gateway has a call control component operable to set up and tear down RTP connections between the networks, a push-to-talk control component operable to arbitrate calls between wireless communications handsets of both networks, and a transmission control component operable to transfer media packets between the networks. The gateway reduces the number of call set ups required when a caller wants to speak because connections may remain active until the talk group participants leave the push-to-talk group call.
摘要翻译：提供了一种用于互连公共安全无线网络和支持一键通电话呼叫的商业无线网络的网关的方法和装置。网关转换从商业无线网络接收的实时协议（RTP），会话邀请协议（SIP）和通话突发控制协议（TBCP）/实时控制协议（RTCP）消息以及从公共安全接收的RTP和SIP消息无线网络成为接收网络的格式。网关具有可操作以建立和拆除网络之间的RTP连接的呼叫控制组件，可操作以仲裁两个网络的无线通信手机之间的呼叫的一键通控制组件和可操作以传送媒体分组的传输控制组件在网络之间。网关减少呼叫者想要发言时所需的呼叫设置次数，因为连接可能保持活动，直到谈话组参与者离开即按即说组呼。

摘要： A method of changing the characteristics of telephone call data on an ATM network that is initially transmitted via a first SVC between a first ATM switch and a second ATM switch is described. The method includes the steps of sending a set-up message for a second SVC from the first ATM switch to the second ATM switch and sending a switch-over request message from the first ATM switch to the second ATM switch via the second SVC. The method further includes the steps of sending a switch-over acknowledge message from the second ATM switch to the first ATM switch via the second SVC and sending a switch-over begin message from the first ATM switch to the second ATM switch via the second SVC. The method further includes the steps of sending a switch-over confirm message from the second ATM switch to the first ATM switch via the second SVC and transmitting the telephone call data via the second SVC. The steps executed by the present invention insure that the switch-over from the first SVC to the second SVC is accomplished without interrupting service.
摘要翻译：描述在第一ATM交换机和第二ATM交换机之间经由第一SVC最初发送的ATM网络上的电话呼叫数据的特性的改变方法。该方法包括以下步骤：将第二SVC的建立消息从第一ATM交换机发送到第二ATM交换机，并经由第二SVC从第一ATM交换机向第二ATM交换机发送切换请求消息。该方法还包括以下步骤：经由第二SVC从第二ATM交换机向第一ATM交换机发送切换确认消息，并经由第二SVC从第一ATM交换机向第二ATM交换机发送切换开始消息。该方法还包括以下步骤：经由第二SVC从第二ATM交换机向第一ATM交换机发送切换确认消息，并通过第二SVC发送电话呼叫数据。本发明执行的步骤确保在不中断服务的情况下实现从第一SVC到第二SVC的切换。
