摘要： Intelligent call forwarding is implemented through an intelligent network. The intelligent network includes a Service Switching Point (SSP), a Service Control Point (SCP), and a Service Management System (SMS). A call to a network subscriber is routed to the SSP which is used to detect Call Forwarding "triggers"--conditions which require the SSP to initiate selective Call Forwarding service. When a Call Forwarding trigger is detected the SSP passes the calling party's number to the SCP and requests call handling instructions from the SCP. The SCP provides the call handling instructions, as provisioned by the subscriber, to the SSP, and the SSP then forwards the call in accordance with the instructions. The SMS formulates and sends commands to the SCP for such purposes as changing the stored subscriber instructions or updating service features. By provisioning the SCP with appropriate instructions the forwarding destination for a call may be made to depend upon the time of day, day of the week, caller's identity, and/or status of the called telephone.

摘要： A Call Message Delivery system (CDS) enables an attendant to control the delivery of a recorded call message from a caller to a specified party at a called station. The CDS alerts the attendant at a delivery time, selected by either the caller or the system. When the attendant determines that the specified party has answered the call at the called station, the caller's recorded call message is outputted to the specified party. If the specified party is not available, the attendant may schedule the call for a later delivery or may forward the call to another station specified by the answering party at the called station.

摘要翻译： 呼叫消息发送系统（CDS）使得话务员能够控制在被叫站处从呼叫者到指定方的记录的呼叫消息的传送。 CDS通过呼叫者或系统选择的交付时间向服务员发出警报。 当服务员确定指定方已经在被叫站处应答呼叫时，主叫方的记录呼叫消息被输出到指定方。 如果指定方不可用，话务员可以安排该呼叫以供后续发送，或者可以将该呼叫转发到由被叫站的应答方指定的另一台。

摘要： A communication system includes a network switch coupled through a telephone line uniquely associated with each customer for budgeted telephone calling time and amount, either pre-paid or post-paid, the budgeted amount being recorded in the system for calling purposes. A server is coupled to the switch for automated control of the budgeted telephone calls and costs. The server includes a control processor having access to databases for recorded budgeted amounts and call routing. A voice response unit is coupled to the processor and sends messages to the calling customer at the beginning of each budget telephone call indicating remaining budgeted telephone calling time and amount available to the calling purposes. The processor debits the customer account by an amount reflecting the call costs as the call proceeds. A voice message advises the calling customer when the available time and costs for the budgeted telephone call will terminate. Depending upon customer preference, the call may (i) terminate when the budget amount is exceeded or (ii) continue subject to a warning that the call budget has been exceeded with a prompt to obtain additional prepaid budgeted calling time and cost or (iii) continue the call and subsequent calls subject to later payment by the calling customer. Calls are placed directly to the calling party without accessing a special toll number or providing a credit card number.

摘要翻译： 通信系统包括通过与每个客户唯一相关联的电话线耦合的网络交换机，用于预算的电话呼叫时间和预付费或后付费的金额，用于呼叫目的记录在系统中的预算金额。 服务器耦合到交换机，用于自动控制预算的电话呼叫和成本。 服务器包括控制处理器，其具有用于记录的预算量和呼叫路由的数据库访问。 语音应答单元耦合到处理器，并且在每个预算电话呼叫开始时向呼叫客户发送消息，指示剩余预算的电话呼叫时间和可用于呼叫目的的数量。 处理器会在客户帐户中扣除反映通话费用的金额。 当预算电话的可用时间和费用将终止时，语音消息建议主叫客户。 根据客户偏好，呼叫可能（i）超出预算金额时终止，或（ii）继续警告，超出呼叫预算，并提示获得额外的预付预算通话时间和费用，或（iii） 继续呼叫和随后的呼叫，受到客户以后的付款。 呼叫直接发送给主叫方，无需访问特殊的收费号码或提供信用卡号码。
