Description

How to Call Back Missed Calls

technical field

The invention relates to a method for calling back a missed call, and in particular to a method for calling back a missed call automatically.

Background technique

With the advent of the era of mobile communication, mobile phones are becoming more and more popular, gradually replacing traditional home phones and becoming one of the indispensable tools for modern people to communicate with others.

Generally speaking, it is inconvenient for the user to answer the mobile phone when driving, meeting, attending class, etc., so there are situations of missed calls. In addition, if the mobile phone is set to silent, vibrate or the ringtone is too low, the user will miss the incoming call without hearing the ringtone. Accordingly, the user should check whether there is a missed call afterwards and call back by himself.

However, currently most of the reminder notifications about missed calls on mobile phones will only be reminded once with sound or vibration. If the user uses the mobile phone after a period of time, the reminder notification of missed calls may be ignored. Accordingly, important matters or meetings will be delayed.

Contents of the invention

The invention provides a missed call callback method to automatically call back the phone number of the missed call.

The invention proposes a missed call callback method, which is suitable for a handheld communication device. The missed call callback method at least includes the following steps: detecting that the handheld communication device is in use or idle. When the handheld communication device is in the idle state, the missed call recording function is activated to record the phone numbers of the missed calls into the callback list. Check the callback list while the handheld communicator is in use. If the phone number is recorded in the callback list, call back the phone number. And, when the phone number is connected, a prompt signal is output.

In an embodiment of the present invention, the step of determining whether the handheld communication device is in use or idle includes detecting whether the input unit of the handheld communication device is locked. If the input unit is not locked, it is determined that the handheld communication device is in use. If the input unit is locked, it is determined that the handheld communication device is in an idle state.

In an embodiment of the present invention, the step of determining whether the handheld communication device is in use or idle includes detecting whether the handheld communication device moves. If the movement of the handheld communication device is detected, it is determined that the handheld communication device is in use. If no movement of the handheld communication device is detected within the preset time, it is determined that the handheld communication device is in an idle state. Here, a gravity sensor, a gyroscope, a global positioning system or an electronic compass may be used to detect whether the handheld communication device is moving.

Detailed ways

At present, the missed call reminder mechanism of mobile phones is not quite proper, and users often forget to answer important calls, thus delaying important matters. For this reason, the present invention proposes a method for calling back missed calls, which can avoid the situation of forgetting to reply important calls. In order to make the content of the present invention clearer, the following specific examples are given as examples in which the present invention can actually be implemented.

FIG. 1 is a schematic structural diagram of a handheld communication device according to an embodiment of the present invention. Please refer to FIG. 1 , the handheld communication device 100 can be a mobile phone or a personal digital assistant (Personal Digital Assistant, PDA) mobile phone, which at least includes a processing unit 110, a communication unit 120 and a storage unit 130. Moreover, the handheld communication device 100 may further include a locking module 140 and a motion detection module 150 .

In this embodiment, the handheld communication device 100 can be divided into two states, that is, an "in-use state" and an "idle state". For example, it is defined that the state in which the handheld communication device 100 executes application program modules (for example, playing games, making calls, listening to music, viewing calendar, etc.) Status is "idle status".

Here, the processing unit 110 can be used to detect that the handheld communication device 100 is currently in use or idle. For example, the processing unit 110 can use the locking module 140 to determine whether the input unit (eg, touch screen or keyboard, not shown here) of the handheld communication device 100 is locked, so as to determine whether the handheld communication device 100 is currently locked. In use or in idle state. When the input device is locked, the processing unit 110 determines that the handheld communication device 100 is in an idle state. When the input device is unlocked, the processing unit 110 determines that the handheld communication device 100 is in use.

Alternatively, the processing unit 110 can also use the movement detection module 150 to detect whether the handheld communication device 100 is moving, so as to determine whether the handheld communication device 100 is currently in use or idle. For example, if the motion detection module 150 detects that the handheld communication device 100 is moving, it is determined that the handheld communication device 100 is in use; The communication device 100 moves, and it is determined that the handheld communication device 100 is in an idle state.

The above-mentioned motion detection module 150 may be a gravity sensor (G-Sensor), a gyroscope (Gyrometer), a global positioning system (Global Positioning System, GPS) or an electronic compass. As far as the gravity sensor is concerned, it is used to detect whether the handheld communication device 100 is deviated (such as tilting, turning over, etc.). The gyroscope is a device used to sense the direction, so as to determine whether the handheld communication device 100 is moving. In addition, taking GPS as an example, most people only open the GPS application module to use when they want to perform positioning and navigation. At this time, the processing unit 110 can detect the current status of the handheld communication device 100 through GPS. When the user is moving, the positioning position of the handheld communication device 100 will also move accordingly, so it is determined that the handheld communication device 100 is in use. And the electronic compass is only when necessary, the user will open the application program module of the electronic compass to use. At this time, the processing unit 110 can detect whether the handheld communication device 100 is moving through the electronic compass.

In addition, the processing unit 110 can also detect whether the handheld communication device 100 currently has an application program module being executed, so as to determine whether the handheld communication device 100 is currently in use or idle. Alternatively, modes such as mute and vibration can also be set to an idle state.

In addition, the processing unit 110 can also use the communication unit 120 to detect the cell identification of the signal transmitting base station of the handheld communication device 100, so as to determine whether the handheld communication device 100 is moving according to the change of the cell identification.

The above-mentioned communication unit 120 is used to establish a call connection, which is used to receive an incoming call or make a call to enter a call mode. The storage unit 130 stores a callback list. When the processing unit 110 determines that the handheld communication device 100 is in an idle state, it will activate the missed call recording function to store the phone numbers of the missed calls in the callback list.

Generally speaking, if the handheld communication device 100 is in an idle state, it means that the user is far away from or has not watched the handheld communication device 100, and thus usually does not pay attention to the status of the handheld communication device 100, resulting in missed calls. Situation happens. Accordingly, in this embodiment, when the handheld communication device 100 is idle and a missed call occurs, the processing unit 110 can automatically record the phone number of the missed call into the callback list. And, when the processing unit 110 determines that the handheld communication device 100 is in use, it will check from the storage unit 130 whether there is a phone number for a missed call recorded in the callback list, so that when the phone number is recorded in the callback list, Call back through the communication unit 120 .

In order to describe the various steps of the missed call callback method more clearly, the following will be described in conjunction with the above-mentioned handheld communication device 100 . FIG. 2 is a flowchart of a method for calling back a missed call according to an embodiment of the present invention.

Please refer to FIG. 1 and FIG. 2 at the same time. In step S205, the processing unit 110 detects that the handheld communication device 100 is in use or idle. As mentioned above, the processing unit 110 can use the locking module 140 to determine whether the input unit of the handheld communication device 100 is locked, or can also use the movement detection module 150 to detect whether the handheld communication device 100 is moving. It can detect whether the application module is being executed in the handheld communication device 100 at present, so as to determine whether the handheld communication device 100 is currently in use or idle. These judgment mechanisms can be used in combination according to different needs.

For example, it is impossible for the user to carry the handheld communication device 100 all the time, so an away mode can be defined in the handheld communication device 100 . When the user enables the away mode in the handheld communication device 100, the movement detection module 150 is activated to detect whether the handheld communication device 100 is moving.

Specifically, when the user intends to temporarily leave the handheld communication device 100 away from his body (for example, place it on a table) to enable the away mode of the handheld communication device 100, the handheld communication device 100 can use the gravity sensor, gyroscope, etc. The movement detection module 150 such as meter, GPS or electronic compass judges whether it is moved. In addition, the communication unit 120 can also be used to detect whether the cell identification code of the signal transmitting base station of the handheld communication device 100 has changed, if changed, it means that the handheld communication device 100 has been moved, if not changed, it means that the handheld communication device 100 is in an idle state middle.

When the handheld communication device 100 is in the idle state, as shown in step S210, the missed call recording function is activated to record the phone numbers of the missed calls in the callback list. Here, the callback list is stored in the storage unit 130 .

When the handheld communication device 100 is in use, as shown in step S215, the processing unit 110 will check whether there is a phone number recorded in the callback list. If no telephone number has been recorded in the callback list, return to step S205. And if the handheld communication device 100 was in idle state before, and there is a phone number for recording a missed call, then when the handheld communication device 100 is switched to the in-use state, the processing unit 110 checks that there is an item in the callback list. phone number, then in step S220, the processing unit 110 will call back the phone number through the communication unit 120.

Afterwards, as shown in step S225, when the phone number is connected, the processing unit 110 uses a prompt module (not shown) to output a prompt signal. The prompt module can be a loudspeaker to output an audio signal (ring). Moreover, the ringing output of the successful callback can also be set to be different from the ringing of a general incoming call, so that the user can distinguish whether it is a general incoming call or a missed call by ringing the ringing.

For example, if the user is driving a car (the handheld communication device 100 is moving), the mechanism of "detecting whether the input unit is locked" can be used to determine whether the handheld communication device 100 is in use or idle medium state. If the user misses an incoming call when the input unit is locked (idle state), the phone number of the missed call will be automatically recorded in the callback list. And when the user unlocks the input unit (in-use state), the handheld communication device 100 will automatically call back to connect to the phone number of the missed call.

In addition, if another telephone number is recorded in the callback list, a telephone number can be selected from the callback list according to a callback priority to call back. For example, the phone numbers of A and B are recorded in the callback list, and A has higher priority than B, then the processing unit 110 will select A's phone number to call back through the communication unit 120 . Moreover, after the callback is completed, the callback list is cleared, so as to avoid confusion with the missed call recorded last time when the handheld communication device 100 enters the idle state again.

In addition, the phone number recorded in the callback list to be called back can also be determined according to the callback priority. That is to say, the user can set a callback priority and select the phone number to be automatically called back, thereby avoiding irrelevant or even wrong phone numbers from being called back.

In summary, the present invention will automatically record the phone number of the missed call when the handheld communication device enters the idle state, so as to automatically call back the phone number of the missed call when the handheld communication device is switched to the active state . And, when the phone number is connected, a prompt signal is output to remind the user. This prevents you from forgetting to answer important calls.

Although the present invention has been disclosed above with the embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be defined by the appended claims.
