1. Technical Field
The present disclosure relates to callback systems, and particularly to a callback system and a method, and a communication terminal using the same.
2. Description of Related Art
After a communication terminal receives a call request, users may choose to hang up and dial back the calling phone number when there is a better calling rate for callback. However, it is inconvenient and complex for the user himself to determine whether there is the better calling rate or not.
Therefore, what is needed is a callback system to overcome the above described limitations.
The processor 12 includes a determining module 102, a callback module 105, a calling rate querying module 103, a prompting module 104, and an implementing module 107. The determining module 102 determines whether or not a phone number of a call request is one of the predetermined phone numbers in the list when the communication terminal 100 receives the call request. The callback module 105 hangs up the call request and dials back the phone number of the call request when the phone number of the call request is one of the predetermined phone numbers in the list. The callback module 105 further prompts the user in a predetermined prompting manner after the call request was hung up and was dialed back by the communication terminal 100. In one embodiment, the predetermined prompting manner may be a prompting music, a vibration or a combination thereof. The calling rate querying module 103 queries a first calling rate of the call, which is initiated from an external communication terminal, and a second calling rate of the call, which is initiated from the communication terminal 100 from the telecommunications operators, and determines whether or not the first calling rate is higher than the second calling rate when the phone number of the call request is not one of the predetermined phone numbers in the list. The prompting module 104 prompts the user whether to select to dial back the phone number of the call request when the first calling rate is higher than the second calling rate. The callback module 105 further hangs up the call request, dials back the phone number of the call request when the user selects to dial back the phone number of the call request. The implementing module 107 processes the call in other means such as, answering/returning the call request in response to a user operation when the user does not select to dial back the phone number of the call request or the first calling rate is not higher than the second calling rate. In other embodiments, the implementing module 107 further processes the call request in other means in response to the operation of the user, when the phone number of the call request is not one of the predetermined phone numbers in the list, thereby omitting the calling rate querying module 103 and the prompting module 104.
The processor 12 further includes a list establishing module 101. The list establishing module 101 establishes the list, and records the number of phone numbers in the list as predetermined phone numbers. The list establishing module 101 further records the first calling rate of the call, which is initiated from the external communication terminal, and records the second calling rate of the call which is initiated from the communication terminal 100 for each of the predetermined phone numbers. The user previously sets the first calling rate and the second calling rate for each of the predetermined phone numbers. As shown in
The processor 12 further includes a calculating module 106. When the phone number of the call request is one of the predetermined phone numbers, the calling rate querying module 103 acquires the first calling rate and the second calling rate of the phone number of the call request from the list after the call which was dialed back by the communication terminal 100 has ended. The calculating module 106 calculates a difference between the first calling rate and the second calling rate and multiplies the difference by a call duration to obtain a call saving, and displays the call saving on the display unit 13. When the phone number of the call request is not one of the predetermined phone numbers, the calling rate querying module 103 acquires the first calling rate and the second calling rate of the phone number of the call request from the mobile telecommunications operator. The calculating module 106 calculates a difference between the first calling rate and the second calling rate and multiplies the difference by a call duration to obtain a call saving, and displays the call saving on the display unit 13. Thus, if the call saving is less than 0 that means the second calling rate is more than the first calling rate, the communication terminal 100 hangs up the call request and dials back the phone number will generate more call cost than the call request is initiated from the external communication terminal.
In step S601, the list establishing module 101 establishes the list, records the number of phone numbers in the list as the predetermined phone numbers, records the first calling rate of the call which is initiated from the external communication terminal, and records the second calling rate of the call which is initiated from the communication terminal 100 for each of the predetermined phone numbers.
In step S602, the determining module 102 determines whether or not a phone number of a call request is one of the predetermined phone numbers in the list when the communication terminal 100 receives the call request, if yes, the procedure goes to step S603, if no, the procedure goes to step S604.
In step S603, the callback module 105 hangs up the call request, dials back the phone number of the call request, and prompts the user in a predetermined prompting manner.
In step S604, the calling rate querying module 103 queries a first calling rate and a second calling rate from the mobile telecommunications operator.
In step S605, the calling rate querying module 103 determines whether or not the first calling rate is higher than the second calling rate, if yes, the procedure goes to step S606.
In step S606, the prompting module 104 prompts the user whether to select to dial back the phone number of the call request, if yes, the procedure goes to step S603.
In step S607, the calculating module 106 calculates a difference between the first calling rate and the second calling rate and multiplies the difference by a call duration to obtain a call saving, and displays the call saving on the display unit 13.
Although various embodiments have been specifically described, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiments without departing from the scope and spirit of the disclosure.
