On the other hand, with the frequent emergency situations such as emergency medical assistance, traffic accidents, natural disasters, etc., the importance of emergency calls is increasing, and the laws and regulations of various countries all call corresponding requirements for emergency calls.

Unlike a general telephone, an emergency call may need to be initiated in any scene, and the worse the environment is, the stronger the user's appeal for the emergency call is, for example, when the user catches fire, the user wants to initiate the emergency call at the fastest speed, and when the user is held by a bandit, the user wants to initiate an alarm without being discovered. Therefore, for emergency calls, it cannot be designed only in the mode of ordinary telephones. The existing emergency call scheme has the defects of complex operation and incapability of meeting the requirement of quick call under emergency.

Disclosure of Invention

The application provides an emergency call method and electronic equipment, which are beneficial to a user to quickly initiate an emergency call in an emergency situation.

In a first aspect, a method for an emergency call is provided, where the method is applied to an electronic device, the electronic device includes a display screen, and the method includes: when the electronic equipment is in a screen locking state, detecting a first operation of a user on the display screen; responding to the first operation, the electronic equipment displays an emergency call interface through the display screen, wherein the emergency call interface comprises one or more emergency call numbers and prompt information, the prompt information is used for prompting that a call is automatically sent to the first emergency call number after the first preset duration is over, and the one or more emergency numbers comprise the first emergency call number; after the first preset duration is over, if the electronic equipment does not detect the operation that the user clicks any one of the one or more emergency call numbers on the display screen, automatically sending a call to an alarm station, wherein the alarm station is an alarm station corresponding to the first emergency call number; and after the communication connection between the electronic equipment and the alarm desk is disconnected, the electronic equipment displays a screen locking interface through the display screen.

In an emergency scene, when a user needs to quickly perform emergency dialing, a dialing option is entered by sliding a special graph, then a desired number is selected for dialing, and if the user cannot continue to operate, the electronic equipment can automatically select the number with the highest priority to automatically initiate a call after the countdown of the preset time length is finished.

In the embodiment of the application, the user can slide the graph on the screen by one hand at any position, and the emergency call can be realized without any operation subsequently. The embodiment of the application integrally reduces the operation steps and time of the emergency call and achieves the purpose of quickly, conveniently and safely initiating the emergency call.

In some possible implementations, the electronic device being in the screen-locking state may include being in a screen-on state or a screen-off state.

In some possible implementation manners, when the electronic device is in a screen-off state and in a screen-locking state, the electronic device may enter a screen-on state (at this time, the electronic device is still in the screen-locking state) after detecting an operation of clicking a power key by a user. At this time, after the electronic device detects a first operation of the user (for example, the user draws a preset gesture on the display screen), the emergency call interface is displayed through the display screen.

With reference to the first aspect, in some possible implementations of the first aspect, after the electronic device automatically places a call to an alert station, the method further includes: when the call connection between the electronic equipment and the alarm desk is established, the electronic equipment automatically turns off the sound of a receiver and a microphone of the electronic equipment; the electronic equipment detects a second operation of pressing a volume up key by the user; in response to the second operation, the electronic device turns on the sound of an earpiece and a microphone of the electronic device.

In the embodiment of the application, the user can initiate an emergency call under the completely concealed condition, and the electronic equipment can automatically close the sound of the receiver and the microphone when the call connection is established, so that the user can be ensured not to find the mobile phone operated under the emergency condition. If the user has the ability to operate the electronic equipment, the normal conversation mode can be recovered by only additionally pressing the volume up key in the emergency conversation, the original contextual model can be recovered by only unlocking once after the conversation is finished, and the user experience is not influenced.

With reference to the first aspect, in some possible implementations of the first aspect, after the electronic device automatically places a call to the alert station, the method further includes: the electronic equipment sends first information to the alarm station, wherein the first information comprises one or more of dual-tone multi-frequency DTMF coded information, short messages or Instant Messaging (IM) information, and the first information is used for prompting a user that the user is in an emergency currently.

In the embodiment of the application, when a user initiates an emergency call, the user can synchronously send the short message, the DTMF coded information or the IM information to the alarm station or the emergency contact, so that the multi-party simultaneous alarm is realized, and the success rate and the timeliness of the alarm are increased.

With reference to the first aspect, in some possible implementations of the first aspect, the method further includes: after the call connection between the electronic equipment and the alarm station is disconnected, if the electronic equipment does not send second information to the alarm station and does not receive third information sent by the alarm station, after a second preset duration since the call connection is disconnected, the electronic equipment automatically initiates redialing to the alarm station, wherein the second information is used for indicating that the electronic equipment is disconnected from the call connection, and the third information is used for indicating that the alarm station is disconnected from the call connection.

In the embodiment of the application, through the emergency call self-healing scheme, the situation that the electronic equipment judges whether the user is hung up or not or the alarm station is hung up in the emergency call is realized, and the redialing can be automatically initiated to the alarm station. Therefore, the operation steps and time of the emergency call of the user can be reduced, and the purpose of quickly and conveniently initiating the emergency call is realized.

In some possible implementations, after the call connection between the electronic device and the alarm station is disconnected, if the electronic device does not send the second information to the alarm station, the electronic device may automatically initiate redialing to the alarm station after a second preset duration from the call suspension.

With reference to the first aspect, in some possible implementations of the first aspect, the method further includes: after the call connection between the electronic device and the alarm station is disconnected, if the electronic device sends fourth information to the alarm station or receives the fourth information sent by the alarm station, after a second preset time length since the call connection is disconnected, the electronic device automatically initiates redialing to the alarm station, wherein the fourth information is used for indicating that the call connection is disconnected due to the fact that a real-time transport protocol (RTP) is overtime.

In the embodiment of the application, through the emergency call self-healing scheme, the situation that the electronic equipment can automatically initiate redialing to the alarm station when judging that the electronic equipment is hung up only due to RTP overtime in emergency call is realized. Therefore, the operation steps and time of the emergency call of the user can be reduced, and the purpose of quickly and conveniently initiating the emergency call is realized.

With reference to the first aspect, in some possible implementations of the first aspect, the method further includes: after the call connection between the electronic equipment and the alarm desk is disconnected, the electronic equipment is automatically adjusted to be in a vibration mode or a mute mode.

In the embodiment of the application, after the call connection between the electronic equipment and the alarm station is disconnected, the electronic equipment can be automatically adjusted to be in a vibration mode or a mute mode, so that the danger of the user caused by the incoming call of the alarm station or other contacts due to the environment can be avoided.

In some possible implementations, if the electronic device detects that the user unlocks, the mode may be automatically restored from the vibration mode or the silent mode to the original mode (e.g., the normal mode).

With reference to the first aspect, in some possible implementations of the first aspect, the priority order of the one or more emergency numbers is factory set or user set.

In the embodiment of the application, the user can set the corresponding relation between the preset gesture and the emergency call number or set the priority order of the display of the emergency number, so that the user can quickly dial the corresponding emergency number under the emergency condition, the operation steps and time of the emergency call are reduced, and the purpose of quickly, conveniently and safely initiating the emergency call is realized.

In some possible implementations, after the call connection between the electronic device and the alarm station is established, the electronic device may automatically switch to a power saving mode and resume after the call is suspended.

For convenience of understanding, the following embodiments of the present application will specifically describe a method for providing an emergency call by taking a mobile phone having a structure shown in fig. 1 and 2 as an example, with reference to the accompanying drawings.

Fig. 3 is a set of Graphical User Interfaces (GUI) of the cellular phone, and the process of making an emergency call by the user is shown from (a) in fig. 3 to (d) in fig. 3.

The GUI is a screen-off display interface of the mobile phone, as shown in fig. 3 (a). The mobile phone shown in (a) of fig. 3 may be in a screen-off state and in a screen-locked state, and when the mobile phone detects an operation of clicking a power key by a user, a GUI as shown in (b) of fig. 3 may be displayed.

It should be understood that, in the embodiment of the present application, the screen locking status may be a locking condition of the mobile phone, and the locking condition includes, but is not limited to: the user sets a password, fingerprint recognition, face recognition, or the like. For example, when the mobile phone is locked, after the user operates the mobile phone on the desktop, the user may click a power key, and the mobile phone enters a screen locking state after detecting that the user has clicked the power key; or if the mobile phone does not detect the user operation within a period of time, the mobile phone automatically enters a screen locking state. When the mobile phone is in the screen locking state, the screen of the mobile phone can be turned off or turned on. For example, after the user presses the power key, the mobile phone may be lighted up and prompted to input a password, and at this time, the mobile phone is still in a screen locking state, but the touch display screen is lighted up; for example, after another user inputs a wrong password, the mobile phone is still in a screen locking state, but the touch display screen of the mobile phone is still lighted.

The non-screen-locking state is relative to the screen-locking state, and when the electronic device is in the screen-locking state, a user can unlock the electronic device by inputting a password, fingerprint recognition, face recognition or other modes. After unlocking, the mobile phone enters a non-screen-locking state.

Referring to the GUI shown in (b) of fig. 3, the GUI is a screen lock interface of a mobile phone. At this time, the mobile phone can be in a bright screen state and in a locked screen state. When the cell phone detects a gesture in which the user strokes an "X" on the display screen, the cell phone may display a GUI as shown in (c) of fig. 3.

Referring to the GUI shown in (c) of fig. 3, the GUI is an emergency call display interface of a cellular phone. As shown in fig. 3 (c), a plurality of emergency call numbers may be displayed on the emergency call display interface. In which an "alarm phone 110", a "fire phone 119", and an "emergency 120" are displayed in this order from the top. Meanwhile, an automatic countdown is also displayed on the emergency call display interface, and the mobile phone automatically initiates an alarm after a preset time (for example, 3 seconds) from entering the emergency call display interface. If the user wishes to place another emergency call, the emergency phone 120 may be clicked before the preset time period ends. When the cellular phone detects an operation in which the user clicks the emergency phone 120, a GUI as shown in (d) of fig. 3 may be displayed.

Referring to the GUI shown in fig. 3 (d), the GUI is a display interface for dialing the emergency call 120.

It should be understood that, in the embodiment of the present application, the electronic device may also be in an unlocked state. When the mobile phone is in a screen-off state and is not locked, the mobile phone can enter a bright screen display interface of the mobile phone after detecting that a user clicks a power key and the like. And then, if the user detects the preset gesture of sliding of the user under the bright screen display interface of the mobile phone, displaying an emergency call display interface as shown in (c) of fig. 3.

In one embodiment, the user may also directly slide the preset gesture on the off-screen display interface shown in fig. 3 (a) to enter the emergency call display interface.

In the embodiment of the application, a user can quickly initiate an emergency call under emergency conditions without unlocking or inputting an emergency number, and dialing can be directly initiated by selecting the number. The embodiment of the application integrally reduces the operation steps and time of the emergency call, and achieves the purpose of quickly, conveniently and safely initiating the emergency call.

FIG. 4 illustrates another set of GUIs provided by embodiments of the present application.

Referring to fig. 4 (a), the GUI is an emergency call display interface of the cellular phone. As shown in fig. 4 (a), a plurality of emergency call numbers may be displayed on the emergency call display interface. In which an "alarm phone 110", a "fire phone 119", and an "emergency 120" are displayed in this order from the top. Meanwhile, an automatic countdown is also displayed on the emergency call display interface, and the mobile phone automatically initiates an alarm after a preset time (for example, 3 seconds) from entering the emergency call display interface.

Referring to (b) of fig. 4, the GUI is another display interface for an emergency call of a cellular phone. As shown in fig. 4 (b), at the end of the countdown of 3 seconds, if the mobile phone does not detect the operation of clicking any emergency call number by the user, the mobile phone may automatically initiate an alarm after the countdown is ended.

Referring to fig. 4 (c), the GUI is a display interface of the dial alarm phone 110. When the countdown is finished, the mobile phone can automatically dial an alarm call.

In an emergency scene, when a user needs to perform emergency dialing quickly, the user can firstly light up the screen and then enter dialing options by sliding special graphics. And then select the desired number for dialing. And if the user cannot continue to operate, after the countdown of the preset time length is finished, selecting the number with the highest priority by default and automatically initiating the call.

It is described above in connection with the GUI of fig. 3 and 4 that the mobile phone can quickly enter the emergency call display interface by sliding the graphic on the screen by the user, and the emergency call can be implemented without any operation of the user after entering the emergency call display interface. Fig. 4 describes a process of automatically initiating an alarm after the mobile phone counts down 3 seconds, and in this embodiment, the user may also set the priority of the emergency call number. The process of setting the display order of each emergency number and the display priority of the emergency call display interface by the user will be described below with reference to the GUI shown in fig. 5 and 6.

FIG. 5 illustrates another set of GUIs provided by an embodiment of the present application.

Referring to fig. 5 (a), the GUI is a screen lock interface of a mobile phone. The screen locking interface can comprise a prompt message of 'the current interface stroke X initiates an alarm' and can prompt a user to carry out custom setting. When the mobile phone detects an operation of the user clicking the definition setting control 501, a GUI as shown in (b) of fig. 5 may be displayed.

Referring to fig. 5 (b), the GUI is a display interface customized for an emergency call. The display interface comprises two setting options of gesture setting and priority setting. When the mobile phone detects an operation of clicking the control 502 by the user, a GUI as shown in (c) in fig. 5 may be displayed.

It should be understood that after seeing the prompt message, the user clicks the "user-defined" button, and the mobile phone may require the user to unlock the mobile phone, and the user may enter the corresponding setting interface after unlocking the mobile phone. Or, after detecting that the user clicks the 'self-defined', the mobile phone directly enters the corresponding setting interface.

Referring to (c) of fig. 5, the GUI sets an interface for a gesture. The gesture setting interface comprises an alarm telephone gesture setting, a fire alarm telephone gesture setting, an emergency call gesture setting, an emergency contact telephone gesture setting, a user-defined setting and the like. When the mobile phone detects an operation of clicking the control 503 by the user, a GUI as shown in (d) of fig. 5 may be displayed.

Referring to fig. 5 (d), the GUI sets a display interface for alert phone gestures. The display interface includes a plurality of gestures "X", "9", and "//". When the handset detects a user tap gesture pattern 504, the alert phone gesture may be set to "X". The next time the mobile phone detects that the user marks an X under the screen locking interface, the mobile phone can enter an emergency call display interface and preferentially display an alarm phone, and other emergency call numbers can be displayed after the alarm phone. If the mobile phone does not detect the operation of selecting one emergency number by the user after the countdown is finished, the mobile phone can automatically select the alarm phone to initiate dialing.

Likewise, the user may also set fire phone gestures, emergency phone gestures, and the like. For example, the user may set the fire alarm phone gesture to "9". When the mobile phone detects that the user marks out '9' under the screen locking interface, the emergency call display interface can be entered, the fire alarm phone is preferentially displayed, and other emergency call numbers can be displayed after the fire alarm phone. If the mobile phone does not detect the operation of selecting one emergency number by the user after the countdown is finished, the mobile phone can automatically select a fire alarm telephone to initiate dialing.

In one embodiment, the user may set only the correspondence between the type of each emergency call number (e.g., an alarm phone, a fire phone, or an emergency phone) and the preset gesture, without setting the correspondence between the specific number and the preset gesture. The mobile phone may query a global parameter list built in the mobile phone according to a Public Land Mobile Network (PLMN) currently residing in the network, and match a corresponding alarm number as a highest priority emergency number, for example, 110 in china, 112 in germany, and 911 in the united states.

FIG. 6 illustrates another set of GUIs provided by an embodiment of the present application.

Referring to fig. 6 (a), the GUI customizes a display interface provided for an emergency call. The display interface comprises two setting options of gesture setting and priority setting. When the mobile phone detects an operation of clicking the control 601 by the user, a GUI as shown in (b) in fig. 6 may be displayed.

Referring to (b) of fig. 6, the GUI is a display interface for emergency call number priority setting. The display interface comprises prompt information 'displaying the sequence of the emergency call after the preset gesture X slides on the screen locking interface'. The user can select the numbers corresponding to the emergency call number 1, the emergency call number 2, the emergency call number 3 and the emergency call number 4 on the display interface. When the handset detects an operation of the user clicking the emergency call number 1, a GUI as shown in (c) of fig. 6 may be displayed.

Referring to (c) in fig. 6, the GUI is a display interface provided for the emergency call number 1. The user can select one telephone number in an alarm telephone, a fire alarm telephone, an emergency center telephone, a user-defined telephone or a mobile phone address list as the emergency call number 1. Referring to (c) of fig. 6, when the mobile phone detects that the user clicks the control 602 corresponding to the alarm phone, the alarm phone may be set to the emergency call number 1. When the next mobile phone detects that the user draws an X under the screen locking interface, the mobile phone can enter an emergency call display interface and display an alarm telephone at the position of the emergency call number 1.

In the embodiment of the application, the user can set the corresponding relation between the preset gesture and the emergency call number or set the priority order of the emergency number display, so that the user can quickly dial the corresponding emergency number under the emergency condition, the operation steps and time of the emergency call are reduced, and the purpose of quickly, conveniently and safely initiating the emergency call is realized.

It should be understood that the process that the user can customize the gesture or priority order corresponding to the emergency call number is described above through fig. 5 and fig. 6; the priority order of the emergency call numbers can be set when the emergency call numbers leave a factory, and the setting by a user can be omitted.

In some cases, the user needs to keep silent when asking for help urgently (for example, criminals are in front of eyes, dangerous animals are nearby, and the like), so that the danger caused by the user and the mobile phone making a sound is avoided, at the moment, help-seeking information needs to be silently sent, the user can sense whether the help-seeking process is successful or not, and the environmental danger source sound can be transmitted to an alarm table to obtain help seeking.

In the embodiment of the application, a silence help-seeking scheme is added, and silence (mute) is defaulted when the callback of the emergency number is received after the emergency number is dialed. After an emergency call is initiated in a blind operation scene, the downlink audio data is closed by default, namely, the ring back tone in the calling process and the sound user end of the opposite party can not hear the ring back tone after the call is established, and the user can press the volume up key once again to realize normal call.

In order to fully ensure the safety of the user in the secret emergency call, after the silent emergency call is finished, the original contextual model is adjusted to be the vibration mode (or the silent mode), and the prompt can be given on the interface. Meanwhile, if the user opens the call hiding switch, after dialing, the user actively hides (deletes the dialing record) and places the call in a background invisible state, the call can not be called back to the foreground by using conventional GUI operation, but the call can be called back to the foreground by supporting special operation, so that danger brought to the user by calling for help in an emergency and calling conditions is avoided.

Fig. 7 illustrates another GUI provided by an embodiment of the present application.

Referring to the GUI shown in (a) of fig. 7, the GUI is a display interface of the dial alarm phone 110. The display interface comprises a prompt message of 'please press the volume up key to hear the voice of the other party in a silent mode'. In the process of dialing the emergency number by the user, the mobile phone can automatically close the downlink audio data. If the other party connects to the telephone, the user does not hear the other party's voice through the handset and speaker. When the mobile phone detects that the user presses the volume up key, the mobile phone can turn on the downlink audio data, and the user can hear the voice of the other party.

Referring to the GUI shown in (b) of fig. 7, the GUI is a display interface after the user has finished dialing the emergency number. The display interface comprises a prompt message that the mode is adjusted to be a vibration mode and the original mode is recovered after unlocking.

When the mobile phone initiates a silent emergency call, the mobile phone enters an emergency dialing interface, at the moment, the mobile phone defaults to the mode of receiving voice information of the other side to be silent, the mobile phone can close the sound of a receiver and a loudspeaker of the mobile phone, and the ring back tone cannot be heard when the call is successfully ringing. After the other party answers and establishes the conversation, the voice of the other party can not be heard, and the voice of the other party is heard by pressing the volume up key under the 'silent mode' prompted by the calling and conversation interface. And after the mobile phone detects that the user presses the volume up key, the call is recovered to be normal.

If the user initiates an emergency call, all subsequent incoming calls may be forced to be adjusted to a vibration mode (e.g., there may be a friend or police call back). And prompting on an interface until the electronic equipment is unlocked once, the environment is considered to be safe and the user can operate the electronic equipment, and the original contextual model (for example, the common mode) is not recovered.

In one embodiment, in order to prevent the emergency help desk from finding that the call is silent and causing the risk of mistaken hang-up because the user loses consciousness after dialing up, the switch setting allows the mobile phone to send Dual Tone Multi Frequency (DTMF) information to prompt the alarm desk.

DTMF technology is that each digit on keyboard of mobile phone is represented by 2 different SINE audio codes. By way of example, table 1 shows a mapping table of numeric and audio codes on a keypad of a mobile phone in DTMF technology.

TABLE 1

1	2	3	A	697Hz
					4	5	6	B	770Hz
7	8	9	C	852Hz
					*	0	#	D	941Hz
1209Hz	1336Hz	1477Hz	1633Hz

On this basis, 26 english letters can be corresponding to 9 gong keys, for example, the number key 6 corresponds to MNO 3 letters, and the number key 7 corresponds to PQRS 4 letters. The SOS code gives out letter corresponding number button, the SOS code is 767, and SOS information can be embedded in the link as long as 767 corresponding dual-frequency SINE wave is sent, and the alarm center is informed.

In one embodiment, to prevent the emergency call from being hung up by mistake, the handset may automatically send DTMF information of the SOS to the alerting station after the call link is connected.

In one embodiment, when the user is inconvenient to make a sound or cannot make a sound, the user can use the corresponding DTMF (dual tone multi frequency) coding silent help-making detailed information to realize the transmission of the channel-associated emergency help-making information in a silent mode through a single digit or a combination of a plurality of digits, and meanwhile, the system can automatically retransmit the information for a plurality of times to ensure the successful reception of the information by the alarm center.

Illustratively, table 2 shows the use of a single numeric key for emergency help events.

TABLE 2

Event(s)	Digital coding	Frequency of transmission	Number of automatic retransmission
				Riot and terrorist	1	1 minute and 12 times	36
Dangerous animal	2	1 minute and 12 times	36
				…	…	…	…

For example, when a user encounters a dangerous animal in the field, it is inconvenient for the user to make a sound. At this time, after the user dials the emergency call number and the call link is connected, the mobile phone may send the corresponding DTMF encoded information to the alarm station by pressing the data key 1, so that the alarm station may also clarify the current scene where the user is located when the user cannot hear the voice.

In one embodiment, the mobile phone can also add an information alarm initiated synchronously with the voice emergency call.

The information alarm modes initiated by the mobile phone include, but are not limited to, the following modes:

(1) And expanding an emergency call database, and adding short message/Instant Messaging (IM) tool alarm numbers for emergency calls corresponding to various regions.

(2) When the user initiates the silent emergency call, the alarm information is synchronously sent to the corresponding short message/IM alarm number.

(3) And providing a GUI interface for a user to synchronously send emergency help-seeking information when the user sets whether to allow the emergency call, and collecting sensitive information such as position information, name and the like (the authority is closed and data is cleared when the emergency call is ended).

(4) The emergency help information content may include user pre-customizable content, such as name, known disease, address or location information for medical emergency help.

In one embodiment, in order to keep the emergency call continuous for a long time, the mobile phone may automatically enter the power saving mode after the emergency call is connected. And the original mode can be restored until the emergency call is ended.

In the embodiment of the application, the user can initiate an emergency call under the completely concealed condition and can not be discovered. If the user has the ability to operate the electronic equipment, the normal conversation mode can be recovered by only pressing the volume up key one step in the emergency conversation, the original contextual model can be recovered by only unlocking once after the conversation is finished, and the user experience is not influenced. When the silent emergency call is initiated, the short message is synchronously sent to the alarm station or the emergency contact person, so that simultaneous multi-party alarm is realized, and the success rate and timeliness of alarm are increased.

Aiming at the situation that the call is abnormally hung up in the emergency call, the embodiment of the application also provides an emergency call self-healing scheme, namely, the call is not the call hung up by the opposite terminal or the local terminal on the signaling, the electronic equipment considers that the call is an involuntary call drop scene of a user, and at the moment, the electronic equipment automatically redials the last emergency number after counting down for N seconds and re-initiates the emergency call.

In some scenes of initiating an emergency call, such as in mountain rescue, traffic accidents, and fast-driving vehicles, the controllability of the current network environment or the user on the terminal may be poor, and once an abnormal call drop occurs in an emergency call, the emergency call is difficult to be re-initiated, which results in failure of emergency help seeking. Therefore, in the embodiment of the application, the self-healing is performed when the electronic equipment side judges that the emergency call is dropped, and the emergency redialing is automatically initiated. In contrast, in the embodiment of the present application, the emergency call scenarios are divided into the following 4 scenarios:

(1) The interface displays an emergency call, and the signaling is the ordinary call flow of the CS;

(2) The signaling is carried out by a CS emergency call flow;

(3) The interface displays an emergency call, and the signaling process is a common call flow of VoLTE;

(4) What the signaling takes is the VoLTE emergency call flow.

In the signaling flow of the CS call, CC _ CONNECT indicates call establishment, and CC _ DISCONNECT indicates call hang-up, including hang-up initiated by the local terminal or hang-up initiated by the opposite terminal. In the signaling flow of the VoLTE call, 200OK corresponding to INVITE indicates that the other party answers and establishes a call, and BYE indicates that the local terminal or the opposite terminal initiates hang-up.

It should be understood that, in the embodiment of the present application, a CS call refers to a call initiated by an electronic device with a network standard of 2G or 3G; the VoLTE call refers to a call initiated by an electronic device with a network standard of 4G or 5G.

Fig. 8 to fig. 11 show four schematic diagrams of call drop redial during an emergency call provided by an embodiment of the present application. Fig. 8 and 9 show the call connection of the electronic device after establishing the connection with the alarm station if the electronic device is not the electronic device or the alarm station is not hung up. Then the electronic device will not send nor receive CC _ DISCONNECT, and then N seconds (e.g., 5 seconds) from the call hang-up, the electronic device may automatically initiate a redial to the alarm station.

Fig. 10 and 11 show that after the electronic device establishes a connection with the alarm station, the electronic device receives or sends hang-up information due to RTP timeout. Then the electronic device may automatically initiate a redial to the alerting station N seconds after the call is suspended.

Fig. 12 is a schematic flow chart of a method 1200 for redialing a dropped call in a CS call scenario provided in an embodiment of the present application. As shown in fig. 12, the method 1200 includes:

s1201, the electronic equipment initiates a CS call.

Illustratively, as shown in fig. 3 (d), when the handset detects that the user clicks the emergency phone 120, the handset may initiate a CS call.

Illustratively, as shown in fig. 4 (c), when the handset detects the end of the countdown, the handset may initiate a CS call to the alert phone 110.

S1202, the electronic device judges whether the interface display is an emergency call.

In the embodiment of the application, when the electronic device judges whether the display on the interface is an emergency call, if the current call of the user is an international universal emergency call number of '120', the current interface can be considered to display the emergency call; if the user calls a regional emergency call number such as "110" or "120" currently, the current interface display may be considered not to be an emergency call.

S1203, if the electronic device determines that the interface display is not an EMERGENCY call, the electronic device determines whether CC _ error _ SETUP is received.

In this embodiment of the application, if the electronic device receives CC _ error _ SETUP, it may determine that the currently called number is an EMERGENCY call number (e.g., "110" or "119") of a region; if CC _ EMERGENCY _ SETUP is not received, it may be determined that the currently called number is not an EMERGENCY call number for a region.

S1204, if the electronic device determines that CC _ empty _ SETUP is not received, the detection is stopped.

S1205, if the electronic device receives the CC _ error _ SETUP, or the electronic device determines that the interface displays an EMERGENCY call, it continues to determine that the CS call is suspended.

In the embodiment of the application, after the electronic device determines that the CS call is hung up, the electronic device can continuously determine the reason of the hanging up, so that whether redialing to the alarm station needs to be automatically initiated or not can be judged.

S1206, the electronic device determines whether CC _ DISCONNECT is received or transmitted.

For example, if the user hangs up the call, the electronic device may send CC _ DISCONNECT to the opposite terminal.

For example, if the peer hangs up the call, the peer may send CC _ DISCONNECT to the electronic device.

S1207, if the electronic device does not receive and does not transmit CC _ DISCONNECT, the electronic device may automatically redial the last emergency number and re-initiate the emergency call.

In this embodiment of the application, if the electronic device does not receive and also does not send CC _ DISCONNECT, the electronic device may consider that the reason for the hanging up of the call is that the user is not voluntarily hanging up due to other reasons (such as poor signal quality), and then the electronic device may automatically initiate the redialing operation. Therefore, the operation steps and time of the emergency call of the user can be reduced, and the purpose of quickly and conveniently initiating the emergency call is realized.

If the electronic device receives or transmits CC _ DISCONNECT, the electronic device stops detecting.

Fig. 13 shows a schematic flowchart of a method 1300 for call drop redial in a VoLTE call scenario provided by an embodiment of the present application. As shown in fig. 13, the method 1300 includes:

s1301, the electronic equipment initiates a VoLTE call.

S1302, the electronic device determines whether the interface display is an emergency call.

S1303, if the electronic device determines that the interface display is not an emergency call, the electronic device determines whether the sos carried in the contact of the INVITE is received.

S1304, if the electronic device determines that the sos carried in the contact of the INVITE is not received, the detection is stopped.

S1305, if the electronic device receives sos carried in the contact of the INVITE, or the electronic device determines that the interface displays an emergency call, it continues to determine that the VoLTE call is suspended.

It should be understood that the processes of S1301-S1305 may refer to the processes of S1201-S1205 in the method 1200, and are not described herein again for brevity.

S1306, the electronic device determines whether to receive or send hang-up information with a real-time transport protocol (RTP) timeout reason.

S1307, if the electronic device receives or sends the hangup message due to the hangup reason being the RTP overtime, the electronic device may automatically redial the last emergency number and re-initiate the emergency call.

In the VoLTE call, after the call connection between the electronic equipment and the alarm station is disconnected, the electronic equipment receives the information that the disconnection of the call connection is caused by the timeout of a real-time transport protocol (RTP), and then the electronic equipment can automatically initiate redialing to the alarm station; or, the electronic device sends the information that the disconnection of the call connection is caused by the timeout of the real-time transport protocol RTP to the alarm station, and the electronic device may also automatically initiate redialing to the alarm station. Therefore, the operation steps and time of the emergency call of the user can be reduced, and the purpose of quickly and conveniently initiating the emergency call is realized.

If the electronic device does not receive or send hang-up information due to the reason that the RTP is overtime, or if the electronic device receives or sends other hang-up information, the electronic device stops detecting.

The applicable scenes of the technical scheme of the embodiment of the application include but are not limited to the following:

(1) After a traffic accident, an emergency call is initiated, and the call is abnormally dropped, but the user cannot operate the terminal, and then redialing is automatically initiated, so that the user can be rescued in time;

(2) When hijacking happens to a running passenger car, a user only has one alarm opportunity and calls successfully, and the call is dropped due to poor network signals in the moving process, the redial can be automatically initiated.

In the embodiment of the application, through the emergency call self-healing scheme, the electronic equipment can automatically initiate emergency redial due to abnormal reasons in all emergency calls, so that the call success rate is ensured.

Fig. 14 shows a schematic flow chart of a method 1400 for emergency calling provided by an embodiment of the present application. As shown in fig. 14, method 1400 may be performed by an electronic device (e.g., a cell phone), the method 1400 comprising:

s1401, when the electronic device is in the screen lock state, a first operation of a user is detected on the display screen.

Illustratively, as shown in fig. 3 (b), the first operation may be an operation in which the user strokes "X" on the display screen.

In the embodiment of the present application, the type of the first operation is not limited. The first operation may be a preset gesture (e.g., "X", "9", "//"); alternatively, the first operation may be a blank gesture.

S1402, in response to the first operation, the electronic device displays an emergency call interface through the display screen, where the emergency call interface includes one or more emergency call numbers and a prompt message, the prompt message is used to prompt that a call is automatically sent to a first emergency call number after a first preset duration expires, and the one or more emergency call numbers include the first emergency call number.

Illustratively, as shown in (c) of fig. 3, the emergency call interface includes 3 emergency numbers "110", "119", and "120" and a prompt message, which is "automatically set off an alarm after 3 seconds".

S1403, after the first preset duration is over, if the electronic device does not detect an operation of the user clicking any emergency call number of the one or more emergency call numbers on the display screen, the electronic device automatically sends a call to an alarm station, where the alarm station is an alarm station corresponding to the first emergency call number.

For example, as shown in (a) and (b) of fig. 4, when the handset does not detect the operation of the user clicking any one of the 3 emergency numbers after 3 seconds, the handset may automatically initiate a call to the highest priority emergency call number "110" after 3 seconds.

And S1404, after the call connection between the electronic equipment and the alarm desk is disconnected, the electronic equipment displays a screen locking interface through the display screen.

In the embodiment of the application, the user can complete the emergency call under the screen locking interface when the user makes the emergency call, that is, the electronic device does not need to enter a non-screen locking state to complete the emergency call. Therefore, after the call connection between the electronic equipment and the alarm desk is disconnected, the electronic equipment can continue to display the screen locking interface through the display screen.

In an emergency scene, when a user needs to quickly carry out emergency dialing, a dialing option is accessed by sliding a special graph, then a desired number is selected for dialing, and if the user cannot continue to operate, after the countdown of the preset duration is finished, the electronic equipment can automatically select the number with the highest priority to automatically initiate a call.

Optionally, after the electronic device automatically places a call to the alarm station, the method 1400 further includes:

when the call connection between the electronic equipment and the alarm desk is established, the electronic equipment automatically turns off the sound of a receiver and a microphone of the electronic equipment;

the electronic equipment detects a second operation of pressing a volume up key by the user; in response to the second operation, the electronic device turns on the sound of an earpiece and a microphone of the electronic device.

Illustratively, as shown in fig. 6 (a), when a call connection between the electronic device and the alerting station is established, the electronic device may automatically turn off the sound from the alerting station. And displays "in silent mode, please press volume up key to hear the voice of the other party" through the display screen. After the mobile phone detects that the user presses the volume up key, the mobile phone can play the sound from the alarm desk through the receiver or the loudspeaker.

Optionally, after the electronic device automatically places a call to the alert station, the method 1400 further includes:

the electronic equipment sends first information to the alarm station, wherein the first information comprises one or more of dual-tone multi-frequency DTMF coded information, short messages or Instant Messaging (IM) information, and the first information is used for prompting a user that the user is in an emergency currently.

For example, the handset may automatically send DTMF information of the SOS to the alerting station after the call link is connected.

Optionally, the method 1400 further includes:

after the call connection between the electronic equipment and the alarm station is disconnected, if the electronic equipment does not send second information to the alarm station and does not receive third information sent by the alarm station, after a second preset duration since the call connection is disconnected, the electronic equipment automatically initiates redialing to the alarm station, wherein the second information is used for indicating that the electronic equipment is disconnected from the call connection, and the third information is used for indicating that the alarm station is disconnected from the call connection.

For example, in a CS call, if the call connection between the electronic device and the alarm station is disconnected, the electronic device does not send CC _ DISCONNECT to the alarm station, and the electronic device does not receive CC _ DISCONNECT sent by the alarm station, the electronic device may determine that the call is interrupted due to other reasons. The electronic device may automatically initiate a redial to the alert station. Therefore, the operation steps and time of the emergency call of the user can be reduced, and the purpose of quickly and conveniently initiating the emergency call is realized.

Optionally, the method 1400 further includes:

after the call connection between the electronic device and the alarm station is disconnected, if the electronic device sends fourth information to the alarm station or receives the fourth information sent by the alarm station, after a second preset time length since the call connection is disconnected, the electronic device automatically initiates redialing to the alarm station, wherein the fourth information is used for indicating that the call connection is disconnected due to the fact that a real-time transport protocol (RTP) is overtime.

For example, in a VoLTE call, after the call connection between the electronic device and the alarm station is disconnected, the electronic device receives information that the disconnection of the call connection is caused by the timeout of the real-time transport protocol RTP, and then the electronic device may automatically initiate redialing to the alarm station; or, the electronic device sends the information that the disconnection of the call connection is caused by the timeout of the real-time transport protocol RTP to the alarm station, and the electronic device may also automatically initiate the redial to the alarm station. Therefore, the operation steps and time of the emergency call of the user can be reduced, and the purpose of quickly and conveniently initiating the emergency call is realized.
