Hereinafter, the preferred embodiments of the present invention will be described in detail.
The basic idea of the present invention is to enable a user to not only hear a voice signal or voice prompts about a menu but also see the menu or the help information of the menu by eyes (visually) during communication between the user and an IVR system via user equipment. In more detail, the IVR system not only sends to the user equipment a voice signal explaining the current level of a menu but also generates a message explaining the current level of the menu, such as a Short Message Service (SMS) message, a Multimedia Messaging Service (MMS) message and the like, and sends the message to the user equipment.
Normally, an IVR system will send to user equipment a plurality of messages corresponding to different levels of a menu. Since a conventional message sending system is an asynchronous system, i.e. it cannot ensure that the sending order of messages corresponding to different levels of the menu is completely the same as the receiving order thereof. In other words, messages such as SMS messages, MMS messages, and the like do not synchronize with the corresponding voice signals, i.e., the voice signal received at user equipment at a particular moment might be asynchronous with the message received simultaneously. Therefore, an embodiment of the present invention also proposes a scheme for solving this problem concerning synchronization.
In more detail, in this embodiment, in the IVR system aspect, a flag is added to a message (e.g. the message header) when the IVR system generates the message. For example, the flag may comprise a key sequence in which the user operates the keys on the user equipment. On the user equipment aspect, the user equipment records/updates the key sequence in which the user operates the keys on the user equipment, and upon receipt of the message, compares the recorded/updated key sequence in which the user operates the keys on the user equipment with the flag included in the received message. The received message will be displayed if the flag included in the received message corresponds to the recorded/updated key sequence in which the user operates the keys on the user equipment.
In this manner, if the message received at the user equipment corresponds to the voice signal being played, then the message will be displayed on a display screen of the user equipment. The user can see the message and perform a related operation while listening to the voice signal. If, for various reasons, the message corresponding to the voice signal being played is blocked in the message center and is not sent on time, then the message might be received by the user equipment when the voice signal corresponding to the message of next level menu is being played. In this case, the user equipment will not display this message when playing the voice signal corresponding to the message of a next level menu.
Moreover, the IVR system 104 may be connected to a wireless communication network 112 to implement communication between IVR system 104 and a wireless communication device 106 such as a mobile telephone or a Personal Digital Assistant (PDA) for example. In an arrangement, as depicted in
The IVR functionality of communication system 100 can be configured using a management terminal 124. Further, the IVR system 104 may be connected to a communication extension set 116. For example, if the user desires service personnel to answer the problem he/she wishes to solve and has pressed the corresponding key, the IVR system 104 may switch the user to a communication extension set 116.
In this embodiment, the user equipment is the wireless communication device 106, for example, such as a mobile telephone. Of course, those skilled in the art should understand that the user equipment may also be a wired communication device 118, for example, a fixed telephone.
When a user desires to communicate with the IVR system 104, he/she calls the IVR system 104 by pressing corresponding keys on the wireless communication device 106. In this embodiment, it is assumed the call number of IVR system 104 is 12345, and the IVR system 104 is an IVR system of a bank call center. In this case, the key sequence the user presses on wireless communication device 106 is 12345. It should be understood that the keys the user presses on the wireless communication device 106 may further comprise an outgoing-call key.
The wireless communication device 106 records this key sequence 12345 and sends out a request for communication setup to the IVR system 104 (step S210).
Upon receipt of this request, just like a conventional IVR system, the IVR system 104 sends a first voice signal about the first stage menu to the wireless communication device 106 through a voice channel. The first voice signal, for example, comprises a segment of greetings and options the user can choose. For instance, the first voice signal comprises “press 1 for Chinese service, press 2 for English service” (step S220).
At the same time, the IVR system 104 generates a first message 300 that corresponds to the first voice signal. The (
Then, the IVR system 104 sends the first message 300 to the wireless communication device 106 through a signaling channel for example (step S230) (the first message 300 may be in the form of SMS message or MMS message).
It should be understood that the first message 300 is first sent to a message center (not depicted) in the wireless communication network 112 and then forwarded to the wireless communication device 106 by the message center.
Upon receipt of the first message 300, the wireless communication device 106 compares the recorded key sequence “12345” the user presses with the aforesaid first flag 302 “12345”. In this embodiment, the first flag 302 corresponds to the recorded key sequence. Therefore, the wireless communication device 106 automatically displays the first message 300.
In this manner, the user cannot only hear the first voice signal about the menu via the user equipment but also see the menu or the help information of the menu being displayed on the display screen of the user equipment. Therefore, he/she can make a corresponding choice quickly (for example, after the user sees the first message 300, he/she can make a corresponding choice without hearing out the first voice signal).
If the first flag 302 does not correspond to the recorded key sequence, the wireless communication device 106 does not display the first message 300.
Having scanned the first message 300 and/or listened to the voice signal, the user presses key 1 on the wireless communication device 106 to choose Chinese service.
The wireless communication device 106 records the user's pressing action, updates the recorded key sequence 12345 as 12345.1, and sends the choice instruction to IVR system 104 (step S240).
Upon receipt of the choice instruction, the IVR system 104 sends a second voice signal about the second stage menu corresponding to the instruction to the wireless communication device 106 through the voice channel. The second voice signal, for example, comprises options the user can choose, such as “press 1 for corporate services, press 2 for personal services” (step S250).
At the same time, the IVR system 104 generates a second message 308 (
Then, the IVR system 104 sends the second message 308 to the wireless communication device 106 through the signaling channel for example (step S260).
Upon receipt of the second message 308, the wireless communication device 106 compares the updated key sequence “12345.1” with the first flag 310 “12345.1” included in the received second message 308. In this embodiment, the first flag 310 included in the received second message 308 corresponds to the updated key sequence. Therefore, the wireless communication device 106 automatically displays the second message 308 on its display screen.
If the first flag 310 in the second message 308 does not correspond to the updated key sequence, the wireless communication device 106 does not display the second message 308.
For the purpose of succinctness, the description of this embodiment is finished here. Having scanned the second message 308 and/or listened to the voice signal, the user can make a corresponding choice.
In this manner, the wireless communication device 106 can play at least one voice signal received from the IVR system 104 in order and display at least one message received from the IVR system 104 in order. The at least one message corresponds to the at least one voice signal respectively.
In other words, according to an embodiment of the present invention, the wireless communication device 106 plays, in order, the at least one voice signal generated by IVR system 104 in order. In this period, the wireless communication device 106 judges whether or not the received message corresponds to the voice signal being played. If yes, then wireless communication device 106 displays the message at the same time; otherwise, it does not display the message. Therefore, for various reasons, if the wireless communication device 106 is unable to receive a message in synchronization with the corresponding voice signal thereof, it does not display the message.
In this manner, it is ensured that the displayed message corresponds to the voice signal being played. If the wireless communication device 106 does not receive a message corresponding to a voice signal during playing the voice signal, then it does not display a corresponding message in this period. Therefore, the problem concerning synchronization between voice signals and messages are solved in a desired way.
In another embodiment of the present invention, as depicted in
At the wireless communication device 106 aspect, there are further comprised the steps of recording information corresponding to the second flag. For example, the information may be the same as the second flag 416, 418, for example, is the number of the IVR system 12345, or may be different from the second flag 416, 418 provided that wireless communication device 106 and IVR system 104 reach an agreement. Another step is comparing the information with the second flag 416, 418, and the conditions for displaying the message further comprise that the information corresponds to the second flag 416, 418.
One advantage of this embodiment is that the wireless communication device 106 can interact with a plurality of IVR systems without being confused.
Of course, those skilled in the art should understand that the first flag is not limited to the key sequence in which the user operates keys on the user equipment to input the instruction sequence. This is true as long as key sequence can reflect the one-to-one correspondence between respective messages and respective voice signals sent by IVR system 104 so that wireless communication device 106 can judge the correspondence. For example, the portion before the dot in the first flag may also be the number of wireless communication device 106 or even any flag (e.g. 0).
Optionally, the first flag 302, 310 may be set as the form of A0A1A2A3A4 . . . , in which A0 may be any character and corresponds to the message corresponding to the first voice signal; A1 is in a value range of a, b, c, . . . , each of them respectively corresponds to respective messages corresponding to the plurality of second voice signals, and so on and so forth. In this case, the wireless communication device 106 may compare information corresponding to the voice signal being played with the first flag 302, 310 of a received message. If the information corresponds to the first flag 302, 310, then the message is deemed to correspond to the voice signal. Otherwise, the message is not deemed to correspond to the voice signal.
In an embodiment, the at least one message each comprises a first flag 302, 310 that can be used for judging whether or not the at least one message corresponds to the at least one voice signal respectively. In another embodiment, the at least one first flag 302, 310 comprises a key sequence in which the user operates the keys on the user equipment to input the instruction sequence. In yet another embodiment, the at least one message each further comprises a second flag 416, 418 that can be used for judging whether or not the at least one message comes from the IVR system. The at least one message, in one embodiment, is transmitted to the user equipment in the form of Short Message Service message. In another embodiment, the at least one message is transmitted to the user equipment in the form of Multimedia Messaging Service message.
According to an embodiment of the present invention, the at least one message each comprises a first flag 302, 310. The first flag 302, 310 comprises a key sequence in which the user operates keys on the user equipment to input the instruction sequence, so that it can be used for judging whether or not the at least one message corresponds to the at least one voice signal respectively. User equipment 50 further comprises a monitoring module 58 that comprises a recording/updating means 582. The recording/updating means 582 is for recording/updating a key sequence in which the user operates keys on the user equipment to input the instruction sequence. The user equipment also includes a comparing means 586 for comparing the recorded/updated key sequence with the first flag 302, 310 included in a received message. If the first flag 302, 310 included in the received message corresponds to the recorded/updated key sequence, then the comparing means 586 causes the outputting means 56 to display this message.
According to another embodiment of the present invention, the at least one message each further comprises a second flag 416, 418 that can be used for judging whether or not the at least one message comes from the IVR system. The recording/updating means 582 is further for recording information corresponding to the second flag 416, 418 and the comparing means 586 is further for comparing the information with the second flag. The conditions for displaying the message by the outputting means 56 further comprise that the information corresponds to the second flag.
