    • An interactive voice response system (102) includes a protocol interface (134) that is adapted to communicate with a plurality of divergent telecommunications networks for voice communications (104, 106, 108, 110). These networks are, for example, a wireline telecommunications network, a CDMA network, a GSM network, and a voice over IP network. A controller (136) is coupled to the protocol interface to receive a plurality of common call control messages from, and to supply a plurality of common call control messages to, the protocol interface. The protocol interface converts control messages from each one of the plurality of divergent telecommunications networks into the plurality of common call control messages for the controller. The controller generates and receives the common call control messages to cause a prompt and collect interaction with a caller that is using a device that is coupled to one of the networks. The common call control messages generated by the controller are converted by the protocol interface into control messages that are appropriate for the particular network that is to receive the control message. That is, the common call control messages are converted to the network's protocol.
    • 交互式语音响应系统(102)包括适于与用于语音通信(104,106,108,110)的多个发散电信网络通信的协议接口(134)。 这些网络例如是有线电信网络,CDMA网络,GSM网络和IP语音网络。 控制器(136)耦合到协议接口以从协议接口接收多个公共呼叫控制消息,并向协议接口提供多个公共呼叫控制消息。 协议接口将来自多个发散电信网络中的每一个的控制消息转换成用于控制器的多个公共呼叫控制消息。 控制器产生并接收公共呼叫控制消息以引起提示并且收集与使用耦合到网络之一的设备的呼叫者的交互。 由控制器生成的公共呼叫控制消息由协议接口转换成适用于要接收控制消息的特定网络的控制消息。 也就是说,公共呼叫控制消息被转换为网络的协议。

    • IMS gateway systems and methods are disclosed for providing mid-session status checking in an IMS network. An IMS gateway system described herein includes a budget control system and a status checking system. When a session has been established in the IMS network, the budget control system performs budget control for the session. Concurrently, the status checking system periodically checks the status of the session. Responsive to the status checking system determining that the session is active, the budget control system continues to perform the budget control for the session. Responsive to the status checking system determining that the session has terminated, the budget control system terminates the budget control for the session. By periodically checking the status of the session, the IMS gateway system advantageously avoids a runaway changing scenario in the IMS network.
    • 公开了用于在IMS网络中提供中间会话状态检查的IMS网关系统和方法。 本文描述的IMS网关系统包括预算控制系统和状态检查系统。 当在IMS网络中建立会话时,预算控制系统对会话进行预算控制。 同时,状态检查系统会定期检查会话的状态。 响应于确定会话活动的状态检查系统,预算控制系统继续执行会话的预算控制。 响应于确定会话已经终止的状态检查系统,预算控制系统终止会话的预算控制。 通过周期性地检查会话的状态,IMS网关系统有利地避免了IMS网络中的失控改变情况。
