    • PROBLEM TO BE SOLVED: To provide an enhanced method for handling a held call in call waiting or three-way calling in a telecommunication system. SOLUTION: A method and an apparatus are disclosed that manage the held calls for an off-premises terminal at the system that extends calls to the terminal, such as a private branch exchange or other type of data-processing system, instead of at the system that receives the extended calls, such as a mobile switching center at which a cell phone is registered. The disclosed technique is based on the observation that the extending system knows of an incoming call to an off-premises terminal before the receiving system. As a result, the extending system can advantageously select the calls that it holds versus the calls that it sends to the receiving system. The extending system can control the routing costs and provide a consistent look-and-feel of call control to the off-premises terminal user. COPYRIGHT: (C)2007,JPO&INPIT
    • 要解决的问题:提供一种在电信系统中处理呼叫等待或三方通话中的保持呼叫的增强方法。 解决方案:公开了一种方法和装置,其管理在延长对诸如专用小交换机或其他类型的数据处理系统的终端的呼叫的系统处的外部外终端的保持呼叫,而不是 在接收到扩展呼叫的系统,诸如移动交换中心,手机在其上被注册。 所公开的技术基于在接收系统之前扩展系统知道到外部终端的呼入的观察。 结果,扩展系统可以有利地选择它所持有的呼叫与其发送到接收系统的呼叫。 扩展系统可以控制路由成本,并为外部终端用户提供一致的呼叫控制外观。 版权所有(C)2007,JPO&INPIT
