Description:
TECHNICAL FIELD 
       [0001]    The present disclosure relates to mobile communication field, and particularly, to a method for providing a voice option and a text prompt using a mobile phone client and a corresponding mobile phone client. 
       BACKGROUND 
       [0002]    Currently, with development of smart mobile phones, there are many ways for a mobile phone to handle an incoming call, such as interception or filtering an incoming call. Personalized options for the mobile phone provide more humanized handlings to users. For example, the mobile phone may be set to refuse any incoming call when its user is asleep, has a meeting, or drives. 
         [0003]    Generally, a function of interception or filtering an annoying call can prompt a user that an incoming call is an annoying call, However, if a personalized setting for refusing an incoming call has been set up by the user, a rejection record merely shows numbers and times of refused calls. 
         [0004]    Similarly, if the mobile phone is set to refuse any incoming call when a user is asleep, the user may see prompts of showing numbers and times of refused calls only. Nevertheless, the user cannot know intention and content of the missed calls, If there are a plurality of missed calls, the user cannot distinguish importance levels and priorities of these calls. 
         [0005]    There are voice mailbox services in prior art, such as a pay voice mailbox service operated by a telecommunication operator. However, the function of the voice mailbox is implemented by recording voice information at a server of the telecommunication operator and prompting a user of a mobile phone via a short message or the like. A prompt received by the user of the mobile phone may include a number of an incoming call dialing the voice mailbox and a time length of recorded voice information, etc. The prompt does not include an importance level or a priority of voice information. If the user of the mobile phone receives multiple pieces of voice information, the user of the mobile phone has to dial a dedicated number for the voice mailbox of the telecommunication operator and listens to the multiple pieces of voice information one by one, so as to learn the importance level or priority of the voice information. 
         [0006]    Accordingly, a solution in which importance levels of missed calls can be distinguished by a user and it is not needed for the user to spend a lot of time to dial the missed calls or listen to voice mails one by one. 
       SUMMARY OF THE INVENTION 
       [0007]    In order to solve the problems in prior art, the present disclosure provides a method for providing a voice option and a text prompt using a mobile phone client. The method comprises answering an incoming call automatically, providing a voice prompt and a corresponding keystroke option to a caller, receiving a record of keystroke option from the caller, converting the record of keystroke option into a corresponding text prompt, and presenting the text prompt to a user of the mobile phone. 
         [0008]    Compared with methods for recording voice mails or prompting missed calls in prior art, the present disclosure enables a user to distinguish importance levels of missed calls, without spending a lot of time to dial the missed calls or listen to voice mails one by one.

     DETAILED DESCRIPTION 
       [0015]    Various embodiments of the present disclosure are described in detail below. Examples of the embodiments are illustrated in the drawings and following description. Although the present disclosure is described in conjunction with exemplary embodiments, it will be appreciated that the present disclosure is not limited thereto. To the contrary, the present disclosure intends to cover not only the exemplary embodiments, but also other alternatives, modifications, equivalents, and embodiments of essentials and scopes of the present disclosure as defined by appended claims. 
         [0016]    The present disclosure provides a method for providing a voice option and a text prompt using a mobile phone client. Embodiments will be described in detail in conjunction with a Symbian operating system. One of ordinary skill in the art can appreciate that solutions of the present disclosure are not limited to the Symbian operating system and can also be applied on the basis of other operating systems. According to an embodiment of the present disclosure, as shown in  FIG. 1 , the method for providing a voice option and a text prompt using a mobile phone client starts with step S 101  at which the client answers an incoming call automatically. Alternatively, the client is a functional module installed on an operating system of a mobile phone. Taking the Symbian operating system as an example, an event of an incoming call is needed to be monitored firstly. The iTelephony interface may be used to monitor a state change: 
         [0000]    NotifyChange (iStatus, CTelephony::EVoiceLineStatusChange,iCallStatusPkg) SetActive( ). Once a voice incoming call occurs, the iTelephony interface is used to activate answering: AnswerincomingCall (iStatus,iCallId); SetActive( ) 
         [0017]    At step S 102 , a voice prompt and a corresponding keystroke option is provided to the caller. The provided voice prompt includes, by default, a reason for entering the voice prompt, such as “the owner of the mobile phone is not available for answering the call at present.” The voice prompt may also include an explanation of operating the keystroke option, such as “please enter a corresponding option after listening to following prompts and press # to confirm.” The voice prompt may also include an explanation of the keystroke option, such as “emergency, call back immediately, please press 1,” “emergency, call back later, please press 2,” “call back by tomorrow, please press 3,” or “no need for call back, please press 4.” These recordings are stored in an internal or external storage of the mobile phone. When the incoming call is answered automatically, a related recording will be played. Taking the Symbian operating system as an example, a piece of voice to be played is selected by using a function of iAudioPlayer-&gt;OpenFile(_L(“audiofilename”)) firstly, and then is played using iAudioPlayer-&gt;Play( ). 
         [0018]    At step S 103 , the client receives a record of keystroke option from the caller. According to an embodiment of the present disclosure, a keystroke signal is converted to a double tone signal through use of Double Tone Multiple Frequency (DTMF) signaling and is transmitted. The client restores the signal to a keystroke option. Taking the Symbian operating system as an example, the client firstly receives a double tone signal in the form of a character string, acquires data of the character string (TRequestStatus iStatus;TBuf&lt;8&gt; iDtmfBuf;TInt iDtmfNum) of the double tone signal by using a function (RMobilePhone iDtmfPhone), reads the data of the character string and converts it into a numerical value (iDtmfPhone.ReadDTMFTones(iStatus, iDtmfBuf); TLex lex(iDtmfBuf); lex.Val(iDtmfNum)). 
         [0019]    At step S 104 , the record of keystroke option is converted into a corresponding text prompt. According to an embodiment of the present disclosure, the client finds, after identifying the double tone signal, a corresponding preset text prompt according to the identified double tone signal, such as “emergency, call back immediately,” “emergency, call back later,” “call back by tomorrow,” or “no need for call back.” The preset text prompt is stored in an internal or external storage of the mobile phone and corresponds to a keystroke signal. The preset text prompt can be edited by the user of the mobile phone and is not limited to the above examples. Text prompts defined by any user can be applied. For example, “priority-important” corresponds to a keystroke signal 1, “priority-general” corresponds to a keystroke signal 2, and “priority-not important” corresponds to a keystroke signal 3. If, after the call is answered automatically, the caller hangs up without entering any option, “the caller does not select” will be prompted. 
         [0020]    At step S 105 , the text prompt is presented to the user of the mobile phone. According to an embodiment of the present disclosure, the text prompt includes numbers and times of missed calls as well as the preset text prompt found in the step S 104 . Alternatively, the presented text prompt is used to present information on incoming calls, which have been automatically answered within a preset time period, in a form of a statement to the user of the mobile phone. As shown in  FIG. 4 , numbers of the missed calls are listed in the left column, and dates and times of the missed calls, prompt options selected by the callers, and the number of times of the missed calls are listed to the right one by one. 
         [0021]    According to an embodiment of the present disclosure, as shown in  FIG. 2 , the method for providing a voice option and a text prompt using a mobile phone client starts with steps S 201 -S 203 , i.e., setting automatically answering and voice mails. At step S 201 , a waiting time before automatically answering the incoming call is set, such as 1 second, two seconds, or three seconds. At step S 202 , a text prompt and a corresponding keystroke option are set. For example, “priority-important” corresponds to a keystroke signal 1, “priority-general” corresponds to a keystroke signal 2, and “priority-not important” corresponds to a keystroke signal 3. If, after an incoming call is answered automatically, the caller hangs up without entering any option, “the caller does not select” will be prompted. At step S 203 , a voice prompt is recorded such as “I cannot answer your call at present, please listen to following options and enter your selection . . . ” 
         [0022]    At step S 204 , the mobile phone receives the incoming call. At step S 205 , the client determines whether the waiting time has reached a preset time length. If so, a voice prompt and a corresponding keystroke option are provided to the caller at step S 206 . At step S 207 , the caller enters a keyboard option according to the voice prompt. For example, if the caller considers his/her call as very important, he/she may enter a keyboard option “1.” At step S 208 , the client receives a record of keystroke option from the caller. At step S 209 , the client identifies the record of keystroke option. At step S 210 , the client finds a text prompt corresponding to the record of keystroke option. For example, the keyboard option “1” corresponds to a text prompt of “priority-important.” At step S 211 , the text prompt is presented to the user of the mobile phone. 
         [0023]    According to an embodiment of the present disclosure, as shown in  FIG. 3 , the method for providing a voice option and a text prompt using a mobile phone client starts with step S 301  at which a mobile device receives an incoming call. At step S 302 , it is determined whether a number of the incoming call is in a black list. The black list includes telephone numbers which are often annoying or related to promote sales. The black list may be a telephone number list stored on the client and may be updated in real time by connecting to a server through a network. The black list may also be a telephone number database stored at the server. When the user needs to check the number of the incoming call, characters of the telephone number is transmitted through a network connection to the server for check. If the number of the incoming call is not in the black list, the client answers the incoming call automatically at step S 305 . 
         [0024]    According to an embodiment of the present disclosure, at step S 303 , the client determines whether a waiting time has reached a preset time length, which is set at the client. If so, the client answers the incoming call automatically at step S 305 . 
         [0025]    According to an embodiment of the present disclosure, at step S 304 , the mobile phone is set to answer any incoming call automatically. 
         [0026]      FIG. 4  shows a record of prompts of missed calls according to an embodiment of the present disclosure. As shown in  FIG. 4 , numbers of missed calls are listed in the left column, and dates and times of the missed calls, prompt options selected by the callers, and the number of times of the missed calls are listed to the right one by one. 
         [0027]      FIG. 5  is a schematic diagram of a mobile phone client  500  for providing a voice option and a text prompt according to an embodiment of the present disclosure. As shown in  FIG. 5 , the mobile phone client  500  comprises an automatically answering module  511 , a voice prompting module  512 , a keystroke option recording module  513 , and a text prompting module  514 . Alternatively, the mobile phone client  500  may further comprise a voice recording module  515 . The automatically answering module  511  communicates with an operating system of the mobile phone and answers an incoming call automatically. The automatically answering module may also start automatically answering according to a waiting time set by the user, or answer any incoming call automatically according to a user setting. The voice prompting module  512  communicates with the automatically answering module  511  and the voice recording module  515 . After the incoming call is answered automatically, the voice prompting module  512  reads a recording stored in the voice recording module  515 , and plays the recording to the caller. The keystroke option recording module  513  communicates with the operating system of the mobile phone, receives and records a record of keystroke option from the caller, and converts the keystroke option into a numerical value. The text prompting module  514  communicates with the keystroke option recording module  513 , reads the numerical value corresponding to the keystroke option from the caller, and presents a corresponding prompt to the user of the mobile phone. The voice recording module  515  may store recordings of voice prompts preset by the user. The voice recording module  515  may be activated according to the numerical value corresponding to the keystroke option to record voice of the caller. In addition, the voice recording module  515  may also store a list of text prompts corresponding to keystroke options.
