    • A telephony system (100) includes a user device (110, 130) configured to enable a user of the telephony system (100) to place and receive telephone calls, and a service node (180, 185) configured to communicate with the user device (110, 130) and to thereby provide the user with an automated voice interface to the telephony system (100) upon the user's initiating access to the telephony system (100) via the user device (110, 130). The automated voice interface permits the user to verbally specify a desired objective corresponding to any one of a number of predefined objectives, the predefined objectives including directory assisted call placement and at least one form of information retrieval. Upon receiving the desired objective from the user, the service node (180, 185) acts to implement the desired objective.
    • 电话系统(100)包括被配置为使电话系统(100)的用户能够放置和接收电话呼叫的用户设备(110,130)以及被配置为与用户设备通信的服务节点(180,185) (110,130),并且由此在用户通过用户设备(110,130)启动对电话系统(100)的接入之后向用户提供自动语音接口到电话系统(100)。 自动化语音接口允许用户口头指定对应于多个预定义目标中的任何一个的期望目标,预定目标包括目录辅助呼叫布置和至少一种形式的信息检索。 在从用户接收到期望的目标时,服务节点(180,185)用于实现期望的目标。

    • A method and system is provided for providing packet data service and circuit switch service during the same session to a mobile station (MS) whose capabilities do not allow such services to be provided thereon by the wireless network according to the its specifications. First, a voice service is provided between the MS and a first client through a switch device, the voice service conforming to a predetermined communication protocol. The MS is then notified about an incoming data service request from a second client to transfer a predetermined amount of data. The voice service is disconnected between the switch device and the MS if the user decides to activate the incoming data service. The voice service between the switch device and the first client is still maintained. The data service from the second client to the MS through the switch device is then established. The data service between the switch device and the MS is disconnected while the data service between the switch and the second client is maintained after the predetermined amount of data has been transferred from the second client to the MS. The voice service between the switch and the MS is re-established if needed. Also, the same client can initiate the voice and packet data service request to the same MS.
    • 提供了一种方法和系统,用于在同一会话期间向移动台(MS)提供分组数据业务和电路交换业务,移动台(MS)的能力不允许无线网络根据其规范在其上提供这样的业务。 首先,通过交换设备在MS与第一客户端之间提供语音服务,语音服务符合预定的通信协议。 然后通知来自第二客户端的传入数据服务请求的MS以传送预定量的数据。 如果用户决定激活传入数据服务,语音服务在交换设备和MS之间断开连接。 交换机设备和第一个客户端之间的语音业务仍然保持。 然后建立从第二客户端通过交换设备到MS的数据服务。 在从第二客户机向MS传送预定量的数据之后,切换设备和MS之间的数据业务被断开,同时在交换机与第二客户端之间的数据业务被维持。 如果需要,交换机和MS之间的语音业务将重新建立。 另外,同一个客户端也可以向相同的MS发起语音和分组数据业务请求。
