    摘要： The disclosure discloses a method for controlling a transfer of a subscriber and a Service Control Point (SCP), which relate to the field of mobile communications and are intended to solve the problem arising from allowing a subscriber to perform a transfer operation during a call in a pre-paid service in the prior art. The method for controlling a transfer of a subscriber includes: an SCP receives a transfer request message from a subscriber; after the transfer request message is received by the SCP, the SCP determines a status of the subscriber, and generates a result of the determination; when the result of the determination is that the subscriber is in a call, the SCP performs no transfer; and when the result of the determination is that the subscriber is not in a call, the SCP performs a transfer on a balance of a pre-paid account of the subscriber according to the transfer request message. The disclosure can reduce a loss of an operator.

    摘要： A method (100) is disclosed such that when a call is being set up (104) from or to a mobile (or fixed) pre-paid subscriber, a portion of the value in the subscriber's pre-paid account is withdrawn (114, 120) to cover the cost of the call. Preferably, the amount withdrawn (114, 120) is large enough to cover the cost for a call of typical duration (e.g., 4 minutes). At call set up (104), for example, in an Intelligent Network (10), this amount is withdrawn (114, 120) from the account and allocated to the call being set up. If this amount is not completely used up, the remainder is returned (146) to the pre-paid account. If, however, the allocated amount is depleted (124) before the call is completed, a second allocation or withdrawal from the account is requested for that call. If the value left in the account is large enough to cover the second withdrawal request, a second amount is withdrawn (114, 120) and allocated to cover the ongoing call. If needed, additional withdrawals (114, 120) can be made to cover the ongoing call until it is completed. Once the call is completed (142), any remainder of the allocated amount is returned (146) to the pre-paid account. Consequently, a pre-paid subscriber can have a plurality of parallel ongoing calls, and because the amount in the pre-paid account is being monitored (116, 122) and accounted for before or while the calls occur, there is no risk that these calls will not be covered by the amount in the pre-paid account.
