CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of U.S. patent application Ser. No. 14/829,817 filed on Aug. 19, 2015, which is a continuation of International Patent Application No. PCT/CN2014/079660 filed on Jun. 11, 2014.

     TECHNICAL FIELD 
     The present disclosure relates to communications technologies, and in particular, to a method for quickly starting an application service, and a terminal. 
     BACKGROUND 
     Currently, a smartphone becomes an important communication tool in people&#39;s life, and quickly making a call anytime anywhere is a basic appeal of person-to-person communication. Currently, for making a call by using a smartphone, the steps usually include selecting a dial-up tool, inputting a number in a dial-up interface, tapping a call button, and then calling out. In addition, the dial-up interface is usually combined with an address book. A user may also select a contact from the address book, enter a details interface of the contact, and then tap a dial-up button to call out. A button-pressing operation of at least three steps is required in this dial-up process. If the smartphone is in a screen-off state or a standby state (and a screen lock is set for the mobile phone), for making a call, the steps further include lighting up a screen and unlocking the screen. However, because of a limitation of a battery life, a smartphone is in a standby or screen-off state for most time. In this case, if the user needs to make a call, a button-pressing operation with at least five steps is required. Therefore, current steps for making a call by using a smartphone are relatively complex and not user-friendly. Therefore, a realistic user demand to be urgently resolved is to implement quickly making of a call on a smartphone by a user by performing fewer button-pressing operations. 
     To enable a user to quickly make a call on a smartphone, in the prior art, a voice of the user is converted into a text by an application, such as a voice assistant, on the smartphone and by using a speech recognition technology, so as to become an instruction of a smartphone system, that is, a call can be made by means of voice input. 
     However, in the prior art, for starting a voice application, a microphone (Mic) needs to be occupied for recording, and if the voice application is used in the case of screen-off, a recording device in a background needs to perform recording for a long time, and an application processor (AP) cannot be on standby for a long time, thereby increasing power consumption of a smartphone and affecting a battery life of the smartphone.

     DESCRIPTION OF EMBODIMENTS 
     To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following clearly describes the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are a part rather than all of the embodiments of the present disclosure. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure. 
     A terminal, namely, a user equipment, in this application may be a wireless terminal or a wired terminal. The wireless terminal may refer to a device that provides a user with voice and/or data connectivity, a handheld device with a radio connection function, or another processing device connected to a radio modem. The wireless terminal may communicate with one or more core networks through a radio access network (RAN). The wireless terminal may be a mobile terminal, such as a mobile phone (also referred to as a “cellular” phone) and a computer with a mobile terminal, for example, may be a portable, pocket-sized, handheld, computer built-in, or in-vehicle mobile apparatus, which exchanges voice and/or data with the radio access network. For example, it may be a device such as a personal communication service (PCS) phone, a cordless telephone set, a Session Initiation Protocol (SIP) phone, a wireless local loop (WLL) station, or a personal digital assistant (PDA). The wireless terminal may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile terminal, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a user equipment. 
     The technical solutions of the present disclosure may be applicable to any scenario in which a terminal is in a screen-on state, a black screen state with a running AP, and a black screen state with a standby AP. A black screen refers to a screen-off state, that is, a state in which a screen of the terminal is powered off. Further, in the embodiments of the present disclosure, the black screen may further include a screen locked state that is presented after the screen is lighted up in the screen-off state, that is, an initial status of the terminal is the screen-off state, and after a user lights up the screen, the terminal is presented in a screen locked state. The state of black screen with a running AP refers to a state in which the terminal is in the screen-off state, but some applications in a background still run. For example, when the screen of the terminal is off, some instant messaging software (such as WeChat) still runs in the background; in this case, the AP is in a running state. The state of black screen with a standby AP refers to a state in which the terminal is in the screen-off state, and no application runs in the background. 
       FIG.  1    is a schematic flowchart of Embodiment 1 of a method for quickly starting an application service according to the present disclosure. As shown in  FIG.  1   , the method may include the following steps. 
     S 101 . A terminal acquires event trigger information, where the event trigger information is used to start application service software on the terminal. When a user needs to quickly start an application service on the terminal, the user may perform a related trigger operation on the terminal, so that a processing chip inside the terminal can acquire the event trigger information according to the trigger operation of the user, and report the event trigger information to an operating system of the terminal. Optionally, a related event triggered by the user on the terminal may be a button event (pressing a button only once), and may be a sensor sensing event, such as a gravity sensing event or a speed sensing event. For example, when the user holds down a physical button of a smartphone, the smartphone responds to a button event of the user, that is, converts the button event into event trigger information (the event trigger information may include a signal, data, and the like after conversion), and reports the event trigger information to an operating system of the smartphone. 
     S 102 . The terminal starts the application service software after determining that the event trigger information meets a preset quick startup condition. After acquiring the event trigger information, the operating system of the terminal performs encapsulation and classification processing on the event trigger information, that is, the operating system of the terminal determines a type of the event trigger information, determines, according to the type of the event trigger information, a quick startup condition corresponding to the event trigger information, and then determines whether the event trigger information meets the determined quick startup condition. Optionally, the quick startup condition may be determining whether a time of acquiring the event trigger information exceeds a preset time threshold, or may be determining whether the type of the event trigger information matches information preset in the terminal, or may further be whether content included in the event trigger information is the same as information preset in the terminal, or may further be another determining condition. If a result of the determining is that the event trigger information meets the quick startup condition, the terminal starts corresponding application service software. Optionally, performing a different trigger operation by the user can enable the terminal to acquire different event trigger information, and different event trigger information is corresponding to different application service software. For example, if the user currently wants to start a voice service, when the user holds down a physical button (such as a volume down button) on the terminal, the event trigger information obtained by the terminal is information about voice service software. That is, a trigger operation performed by the user, event trigger information acquired by the terminal according to the trigger operation performed by the user, and an application service software that needs to be started are corresponding to one another. Optionally, the application service software may be voice dial-up software, and may be instant messaging software such as WeChat, QQ electronic mail, or a short messaging service. 
     S 103 . The terminal acquires a voice instruction input by a user, and runs the application service software according to the voice instruction. After starting the application service software, the terminal may receive voice input of the user. Accordingly, a recording device in a background starts recording at this time. Optionally, after starting the application service software, the terminal may notify, in a manner of vibrating or playing an alert tone, the user that the voice instruction can be currently input. After receiving the voice instruction input by the user, the terminal runs the application service software according to the voice instruction input by the user, so as to provide a corresponding application service for the user. For example, when the user needs to make a call to “XXX”, the user may input “call XXX” by means of voice. In this case, after recording the voice instruction, the recording device in the background of the terminal triggers the voice service software to respond to the voice instruction input by the user, that is, a speech recognition system in the terminal converts the received voice instruction into a text instruction, and then acquires call information (that is, application service information) according to the text instructions. For example, if the voice instruction is “call XXX”, the application service information acquired by the terminal is a number of XXX. After the terminal obtains the call information, a quick call system in the terminal starts a call service. 
     In the prior art, when a terminal is in a black screen state with a running AP, and when the terminal needs to provide an application service for a user, application service software is usually started by means of voice wake-up, so that the terminal provides a corresponding application service. In this case, a recording device in a background of the terminal needs to be always in a recording state from the voice wake-up, and after the application service is provided for the user, the recording device in the background is still in the recording state, so as to be ready to receive voice instruction input of the user anytime. Therefore, power consumption of the terminal is relatively large because the background performs recording all the time. However, regardless of whether a terminal is in a black screen state with a running AP or a black screen state with a standby AP, in the present disclosure, application service software is started by using event trigger information on the terminal, a recording device in a background starts to run only after the application service software is started, so as to receive a voice instruction of a user, and after the terminal provides an application service for the user, the background stops recording. Therefore, power consumption brought by the recording device in the background is reduced. It should be noted that when a terminal is in a black screen state with a standby AP, and after a user performs a trigger operation on the terminal, the terminal needs to start the AP, and then can acquire event trigger information. 
     According to the method for quickly starting an application service provided in this embodiment of the present disclosure, a terminal acquires event trigger information, and starts application service software after determining that the event trigger information meets a preset quick startup condition, so as to provide a corresponding application service for a user. According to the method provided in this embodiment of the present disclosure, application service software is started by using event trigger information, so that a background of a terminal starts to perform recording only after the application service software is started, and background recording is stopped after the terminal provides an application service for a user, preventing a recording device in the background of the terminal from being always in a recording state, and further reducing power consumption of the terminal. 
       FIG.  2    is a schematic flowchart of Embodiment 2 of a method for quickly starting an application service according to the present disclosure. The method involved in this embodiment is a process in which a call is quickly made on a terminal, that is, the application service software in the foregoing Embodiment 1 is dial-up application software. As shown in  FIG.  2   , the method may include the following steps. 
     S 201 . A terminal acquires event trigger information, where the event trigger information is used to start dial-up application software. When a user needs to quickly make a call on the terminal, the user may perform a related trigger operation on the terminal, so that a processing chip inside the terminal can acquire event trigger information according to the trigger operation of the user, and report the event trigger information to an operating system of the terminal. The event trigger information is used to start the dial-up application software, and the dial-up application software may be voice dial-up software. Optionally, the terminal may acquire the event trigger information in a screen-on state. Optionally, the terminal may acquire the event trigger information in a black screen state. For example, the terminal may acquire the event trigger information in a black screen state with a running AP, may further acquire the event trigger information in a black screen state with a standby AP, and may further acquire the event trigger information in a black screen state with the terminal having a secure screen lock. This embodiment of the present disclosure sets no limitation on a scenario in which the event trigger information is acquired. 
     S 202 . The terminal starts the dial-up application software after determining that the event trigger information meets a preset quick startup condition. After acquiring the event trigger information used to start the dial-up application software, the operating system of the terminal determines a type of the event trigger information, determines, according to the type of the event trigger information, a quick startup condition corresponding to the event trigger information, and then determines whether the event trigger information meets the determined quick startup condition. Optionally, the quick startup condition may be determining whether a time of acquiring the event trigger information exceeds a preset time threshold, or may be determining whether the type of the event trigger information matches information preset in the terminal, or may further be determining whether content included in the event trigger information is the same as information preset in the terminal, or may further be another determining condition. If a result of the determining is that the event trigger information meets the quick startup condition, the terminal starts the dial-up application software. 
     S 203 . The terminal acquires a voice instruction input by a user, and runs the dial-up application software according to the voice instruction. After starting the dial-up application software, the terminal may receive voice input of the user. Accordingly, a recording device in a background starts recording at this time. Optionally, after starting the dial-up application software, the terminal may notify, in a manner of vibrating or playing an alert tone, the user that the voice instruction can be currently input. After receiving the voice instruction input by the user, the terminal runs the dial-up application software according to the voice instruction input by the user. For example, when the user needs to make a call to “XXX”, the user may input “call XXX” by means of voice. In this case, after recording the voice instruction, the recording device in the background of the terminal triggers the dial-up application software to respond to the voice instruction input by the user, that is, a speech recognition system in the terminal converts the received voice instruction into a text instruction, and then acquires call information (that is, application service information) according to the text instructions. For example, if the voice instruction is “call XXX”, the application service information acquired by the terminal is a number of XXX. After the terminal obtains the call information, a quick call system in the terminal starts a call service. Optionally, the terminal may receive, in the case of screen-on, the voice instruction input by the user. Optionally, the terminal may further receive, in a black screen state, the voice instruction input by the user. For example, the terminal may receive, in a black screen state with a running AP, the voice instruction input by the user, may further receive, in a black screen state with a standby AP, the voice instruction input by the user, and may further receive, in a black screen state with the terminal having a secure screen lock, the voice instruction input by the user. This embodiment of the present disclosure sets no limitation on a scenario in which the voice instruction input by the user is received. 
     According to the method for quickly starting an application service provided in this embodiment of the present disclosure, a terminal acquires event trigger information, and starts dial-up application software after determining that the event trigger information meets a preset quick startup condition, so as to provide a corresponding application service for a user. According to the method provided in this embodiment of the present disclosure, dial-up application software is started by using event trigger information, so that a background of a terminal starts to perform recording only after the dial-up application software is started, and background recording is stopped after the terminal provides a dial-up service for a user, preventing a recording device in the background of the terminal from being always in a recording state, and further reducing power consumption of the terminal. 
       FIG.  3    is a schematic flowchart of Embodiment 3 of a method for quickly starting an application service according to the present disclosure. This embodiment involves a process in which a user triggers, by using a button, a terminal to start an application service. As shown in  FIG.  3   , the method may include the following steps. 
     S 301 . A terminal receives a button startup event that is input by a user by performing an operation on a physical button. When the user needs to quickly start an application service on the terminal, the user may perform a button-pressing operation on the terminal, that is, the user may input the button startup event to the terminal by performing the button-pressing operation. 
     Optionally, the terminal receives the button startup event that is input by the user by performing an operation on the physical button once, that is, the button startup event is input by the user to the terminal by performing one button-pressing operation. For example, it is assumed that the terminal is a smartphone, the button startup event of the user may be startup by holding down a physical button of the terminal, such as startup by holding down a volume down button (Volume−), startup by holding down a volume up button (Volume+), startup by holding down a power button, or startup by holding down a shutter button of a mobile phone camera; may further be startup by holding down a Bluetooth headset button, such as startup by holding down a Bluetooth headset dial key, startup by holding down a Bluetooth headset volume down button, or startup by holding down a Bluetooth headset volume up button; and may further be startup by holding down a wired headset button, such as startup by holding down a wired headset volume down button, startup by holding down a wired headset volume up button, or startup by holding down a wired headset play button. Performing an operation on a physical button once by the user to input the button startup event is supported by the terminal, facilitating a user operation. In particular, in a screen-off or screen locked state of the terminal, supporting input of the button startup event by performing one operation improves manipulation efficiency. 
     Optionally, the terminal receives a button startup event that is input by the user by double-tapping a button or tapping a button. 
     S 302 . The terminal acquires the event trigger information according to the button startup event. It should be noted that when the terminal is in a black screen state with a running AP, the terminal may directly acquire the event trigger information according to the button startup event of the user. When the terminal is in a black screen state with a standby AP, after receiving the button startup event of the user, the terminal needs to power on the AP to activate the AP, and then can acquire the event trigger information according to the button startup event. 
     S 303 . The terminal determines whether a trigger time of the button startup event is greater than a preset threshold, and if yes, the terminal starts application service software. When the terminal is in the black screen state with a running AP, after acquiring the event trigger information, the terminal directly performs encapsulation and classification processing on the event trigger information. When the terminal is in the black screen state with a standby AP, the terminal needs to perform self-test and recovery on the AP after the AP is powered on, and the terminal performs encapsulation and classification processing on the acquired event trigger information only after it is detected that a status of the AP is normal. 
     Encapsulation and classification processing performed by the terminal on the event trigger information is determining a type of the event trigger information by the terminal. When the terminal determines that the type of the event trigger information is a button startup event, the terminal determines, according to the type of the event trigger information, that a quick startup condition corresponding to the event trigger information is whether a trigger time of the button startup event is greater than the preset threshold. For example, it is determined whether a time of pressing a button by the user is greater than a preset threshold. If the time of pressing a button by the user is greater than the preset threshold, the terminal starts the application service software. Optionally, when the user presses a different button, it indicates that the user needs to start different application service software. For example, if the user currently wants to start a voice service, when the user holds down a volume down button on the terminal, the event trigger information obtained by the terminal is information about voice service software. If the user currently wants to start a short messaging service, when the user holds down a volume up button on the terminal, the event trigger information obtained by the terminal is information about short messaging service software. That is, a button-pressing operation performed by the user, event trigger information acquired by the terminal according to the button-pressing operation performed by the user, and an application service software that needs to be started are corresponding to one another. 
     S 304 . The terminal receives the voice instruction input by the user. After starting the application service software, the terminal may receive voice input of the user. Accordingly, a recording device in a background starts recording at this time. Optionally, after starting the application service software, the terminal may notify, in a manner of vibrating or playing an alert tone, the user that the voice instruction can be currently input. 
     S 305 . The terminal converts the voice instruction into a text instruction, so as to acquire application service information. After receiving the voice instruction input by the user, the terminal converts the voice instruction into the text instruction according to the voice instruction input by the user, so as to acquire the application service information related to the voice instruction. 
     S 306 . The terminal provides the application service according to the application service information. In an implementation manner of this embodiment of the present disclosure, the terminal may perform an operation of quickly making a call. Optionally, the terminal is a mobile phone. Optionally, the terminal is in a black screen state with a running AP. Optionally, the terminal is in a screen locked state. 
     The user starts application service software by using a button on the smartphone, that is, the user performs one button-pressing operation on the smartphone, for example, holds down a volume down button, so as to input a button startup event to the smartphone. Related hardware of the smartphone responds to the button startup event of the user, which is represented as converting a button event of the user into event trigger information that includes information such as a signal and data, and reporting the event trigger information to an operating system of the smartphone. After receiving the event trigger information, the operating system of the smartphone performs encapsulation and classification processing on the event trigger information, that is, determines a quick startup condition corresponding to the event trigger information (that is, whether a time of holding down a button by the user is greater than a preset threshold), and starts voice service software after determining that the time of holding down a button by the user is greater than the preset threshold. 
     A device in a background of the smartphone starts to perform recording only after the smartphone starts the voice service software, so as to receive voice instruction input of the user. In this case, the voice service software may notify, in a manner of playing an alert tone or vibrating, the user that a voice instruction for making a call, such as “redial”, “call XXX”, or “make a call to XXX”, can be input, where “XXX” is a name of a contact. A speech recognition system in the smartphone converts the received voice instruction into a text instruction, and then acquires application service information (that is, call information) according to the text instructions. For example, if the voice instruction is “redial”, the application service information finally acquired by the smartphone is a call number last time; if the voice instruction is “call XXX”, the application service information finally acquired by the smartphone is a number of XXX. 
     After the smartphone obtains the application service information, a quick call system of the smartphone starts a call service. In this case, the smartphone automatically lights up a screen, automatically hides a secure-lock unlocking interface to display a call interface, and reminds the user of call information, such as a called party or a call number. If the call information is incorrect, the user may directly abort a call process by means of voice or by tapping a call hang-up button. In an entire procedure for starting a voice service, the user requires only one time of button pressing and one time of voice instruction input. 
     After the user finishes the call, that is, the voice service provided by the smartphone for the user is complete, the device in the background of the smartphone stops recording, and the smartphone still displays the secure-lock unlocking interface. During a period of calling and conversation, personal information of the user, such as address book data and personal information that is stored on the mobile phone, is still protected by a secure lock. 
     According to the method for quickly starting an application service provided in this embodiment of the present disclosure, a user inputs a button startup event to a terminal, so that the terminal acquires event trigger information according to the button startup event, and starts application service software after determining that the event trigger information meets a preset quick startup condition, so as to provide an application service for the user. According to the method provided in this embodiment of the present disclosure, application service software is started by using event trigger information, so that a background of a terminal starts to perform recording only after the application service software is started, and background recording is stopped after the terminal provides an application service for a user, preventing a recording device in the background of the terminal from being always in a recording state, and further reducing power consumption of the terminal. In addition, according to the method provided in this embodiment of the present disclosure, a user does not need to light up a screen or unlock a screen, but only needs to perform one button-pressing operation and input one voice instruction, so that a terminal can provide a corresponding application service, which is easy to operate, thereby improving manipulation efficiency and enhancing user experience. 
       FIG.  4    is a schematic flowchart of Embodiment 4 of a method for quickly starting an application service according to the present disclosure. The method involved in this embodiment is a process in which a user starts application service software on a terminal by using a sensor startup event, so that the terminal provides a corresponding application service for the user. As shown in  FIG.  4   , the method may include the following steps. 
     S 401 . A terminal receives a sensor startup event input by a user. When the user needs to quickly start an application service on the terminal, the user may perform a sensing operation on the terminal, and input the sensor startup event to the terminal by using the sensing operation, that is, the terminal may acquire the sensor startup event by sensing a gesture of the user. For example, it is assumed that the terminal is a smartphone, the sensor startup event of the user may be that the user holds an earpiece near an ear of the user, may further be another event that the user quickly swings the smartphone and then stops, and the like. 
     S 402 . The terminal acquires event trigger information according to the sensor startup event. It should be noted that when the terminal is in a black screen state with a running AP, the terminal may directly acquire the event trigger information according to the sensor startup event of the user. When the terminal is in a black screen state with a standby AP, after receiving the sensor startup event of the user, the terminal needs to power on the AP to activate the AP, and then can acquire the event trigger information according to the sensor startup event. Optionally, the sensor startup event input by the user may further be combined with the button startup event in the foregoing Embodiment 2, so that the terminal acquires the event trigger information. 
     S 403 . The terminal determines whether the event trigger information matches event information in a preset event information set of the terminal, and if the event trigger information matches the event information in the preset event information set of the terminal, the terminal starts the application service software. When the terminal is in the black screen state with a running AP, after acquiring the event trigger information, the terminal directly performs encapsulation and classification processing on the event trigger information. When the terminal is in the black screen state with a standby AP, the terminal needs to perform self-test recovery on the AP after the AP is powered on, and the terminal performs encapsulation and classification processing on the acquired event trigger information only after it is detected that a status of the AP is normal. 
     Encapsulation and classification processing performed by the terminal on the event trigger information is actually determining a type of the event trigger information by the terminal. When the terminal determines that the type of the event trigger information is a sensor startup event, the terminal determines, according to the type of the event trigger information, that a quick startup condition corresponding to the event trigger information is whether the event trigger information matches the event information in the preset event information set (the preset event information set of the terminal includes multiple pieces of event information). Optionally, the preset information set may be stored in a form of an entry, or may also be stored in a form of an information base, which is not limited in this embodiment of the present disclosure. If the event trigger information matches the event information in the preset event information set, the terminal starts the application service software. Optionally, when the user inputs a different sensor startup event to the terminal, it indicates that the user needs to start different application service software. For example, if the user currently wants to start a voice service, the user holds the earpiece of the mobile phone near the ear, and the event trigger information obtained by the terminal according to the sensor startup event is information about voice service software. If the user currently wants to start a short messaging service, the user swings the mobile phone, and the event trigger information obtained by the terminal according to the sensor startup event is information about short messaging service software. That is, a sensing operation performed by the user (that is, a sensor startup event input by the user), event trigger information acquired by the terminal according to the sensing operation performed by the user, and an application service software that needs to be started are corresponding to one another. 
     S 404 . The terminal receives the voice instruction input by the user. After starting the application service software, the terminal may receive voice input of the user. Accordingly, a recording device in a background starts recording at this time. Optionally, after starting the application service software, the terminal may notify, in a manner of vibrating or playing an alert tone, the user that the voice instruction can be currently input. 
     S 405 . The terminal converts the voice instruction into a text instruction, so as to acquire application service information. After receiving the voice instruction input by the user, the terminal converts the voice instruction into the text instruction according to the voice instruction input by the user, so as to acquire the application service information related to the voice instruction. 
     S 406 . The terminal provides the application service according to the application service information. In an implementation manner of this embodiment of the present disclosure, the terminal may perform an operation of quickly making a call. Optionally, the terminal is a mobile phone. Optionally, the terminal is in a black screen state with a running AP. Optionally, the terminal is in a screen locked state. 
     The user starts application service software by performing a sensing operation on the smartphone. That is, the user performs one sensing operation on the smartphone. For example, the user holds an earpiece of the smartphone near the ear, so as to input a sensor startup event to the smartphone. Related hardware of the smartphone responds to the sensor startup event of the user, that is, the smartphone first powers on the AP to activate the AP, and then converts the sensor startup event of the user into event trigger information that includes information such as a signal and data, and reports the event trigger information to an operating system of the smartphone. After receiving the event trigger information, the operating system of the smartphone first performs self-test recovery on the AP, and after a status of the AP is normal, encapsulation and classification processing is performed on the event trigger information, that is, a quick startup condition corresponding to the event trigger information (that is, whether the event trigger information matches event information in a preset event information set of the smartphone) is determined, and after it is determined that the event trigger information matches the event information in the preset event information set of the smartphone, voice service software is started. 
     A device in a background of the smartphone starts to perform recording only after the smartphone starts the voice service software, so as to receive voice instruction input of the user. In this case, the voice service software may notify, in a manner of playing an alert tone or vibrating, the user that a voice instruction for making a call, such as “redial”, “call XXX”, or “make a call to XXX”, can be input, where “XXX” is a name of a contact. A speech recognition system in the smartphone converts the received voice instruction into a text instruction, and then acquires application service information (that is, call information) according to the text instructions. For example, if the voice instruction is “redial”, the application service information finally acquired by the smartphone is a call number last time; if the voice instruction is “call XXX”, the application service information finally acquired by the smartphone is a number of XXX. 
     After the smartphone obtains the application service information, a quick call system of the smartphone starts a call service. In this case, the smartphone automatically lights up a screen, automatically hides a secure-lock unlocking interface to display a call interface, and reminds the user of call information, such as a called party or a call number. If the call information is incorrect, the user may directly abort a call process by means of voice or by tapping a call hang-up button. In an entire procedure for starting a voice service, the user requires only one sensing operation and one time of voice instruction input. 
     After the user finishes the call, that is, the voice service provided by the smartphone for the user is complete, the device in the background of the terminal stops recording, and the smartphone still displays the secure-lock unlocking interface. During a period of calling and conversation, personal information of the user, such as address book data and personal information that is stored on the mobile phone, is still protected by a secure lock.
