    • During a telephone call, a transferring party performs an action to cause the telephone call to be transferred. The action causes a switch to send a query to a service control point (SCP) in a public-switched telephone network (PSTN). The SCP determines a transfer telephone number to which the telephone call is transferred. The transfer telephone number can be stored in a subscriber information table. The SCP determines the transfer telephone number and returns the transfer telephone number to the switch sending the query. The switch makes a telephone call to the transfer telephone number to cause a telephone associated with the transfer telephone number to ring. When the telephone associated with the transfer telephone number is answered, the transferring party disconnects from the telephone call to complete the transfer of the telephone call. A services node can also be used to determine the transfer telephone number. In addition, other telephone services, such as three-way calling can be selected by the transferring party.
    • 在电话呼叫期间,转移方执行使呼叫转移的动作。 该动作导致交换机向公共交换电话网(PSTN)中的服务控制点(SCP)发送查询。 SCP确定传送电话的转接电话号码。 转移电话号码可以存储在用户信息表中。 SCP确定传输电话号码,并将传送电话号码返回给发送查询的交换机。 交换机对转接电话号码进行电话呼叫,使与转接电话号码有关的电话响铃。 当与转接电话号码相关联的电话被应答时,转移方从电话呼叫断开以完成电话呼叫的转移。 服务节点还可以用于确定传输电话号码。 此外,转移方可以选择其他电话服务,例如三方通话。
