Detailed Description

The technical solutions in the present application will be described below with reference to the accompanying drawings.

Before the aircraft takes off, if the user does not manually switch the communication mode of the mobile phone to the aircraft mode or the shutdown mode, the mobile phone can always keep the communication mode. After the aircraft takes off, the mobile phone cannot detect the network signal in the high altitude state. When the aircraft lands, the network signal is stable, but when the user surfs the internet through the mobile phone, the user can not surf the internet, the mobile phone still can not be connected with the network, or the user can not connect with the network until waiting for a long time, the internet surfing is performed, the contact time between the user and the outside is prolonged, and the user experience is seriously influenced.

By way of example, fig. 1 shows a schematic illustration of an aircraft flight scenario. As shown in fig. 1, when the aircraft flies at high altitude, the signal strength of the mobile phone is marked as blank, and the signal strength of the mobile phone is 0, that is, the mobile phone cannot detect the network signal. After the aircraft lands, the signal strength mark of the mobile phone is filled with black, so that the signal strength of the mobile phone is full, namely the mobile phone can detect stable network signals, but the mobile phone still cannot be connected with a network, and the user experience is affected.

Researchers analyze this phenomenon and consider that the reason for this phenomenon may be that the cell phone triggered the network injection suppression mechanism. The network injection suppressing mechanism refers to limiting the registered network within a preset time period. For example, in third generation mobile communication technology (3th Generation,3G), the inhibit-to-network mechanism refers to restricting the registered network for 12 minutes. If the mobile phone continuously triggers the network injection inhibition mechanism, the duration of a preset time period in the network injection inhibition mechanism is prolonged.

It should be noted that the network injection suppressing mechanism is merely an example of a name, and the embodiments of the present application are not limited thereto.

It has been found that a handset may trigger a suppressed network injection mechanism in the following cases:

1) After the aircraft lands, the mobile phone periodically registers with the network, but has not been successfully registered, and if the mobile phone fails to register with the network a plurality of times (e.g., 5 times) continuously in a period of time, a network injection suppressing mechanism is triggered. The mobile phone cannot register the network in the network-injection-inhibiting mechanism, and after the network-injection-inhibiting mechanism, the mobile phone can register the network again periodically.

If the mobile phone still continuously registers for a plurality of network failures, the network-injection-inhibiting mechanism is triggered again, the duration of the network-injection-inhibiting mechanism is prolonged, and the prolonged time can even reach several hours.

2) An aircraft may search for a weak net signal at high altitude or prior to landing, where a weak net signal refers to a weak signal strength, for example, in the scenario shown in fig. 1, the signal strength is not satisfactory. The mobile phone can not register the network through the weak network signal, or the mobile phone is refused by the network, or the mobile phone does not respond to the information of the registered network, the network-injection inhibition mechanism is triggered, so that after the airplane lands, the mobile phone is still in the network-injection inhibition mechanism, and the network can not be registered.

In view of this, the embodiments of the present application provide a method and a terminal device for searching a network, which can improve the efficiency of searching a network.

S401, acquiring the aircraft take-off time and the aircraft landing time from the flight application program.

The name of the application for viewing flight information of purchased tickets is merely an example, and embodiments of the present application are not limited in this respect. The flight application may or may not have the function of purchasing the air ticket, which is not limited in this embodiment of the present application.

The flight application may push flight information for the purchased air ticket, for example, the flight application may display the flight information for the purchased air ticket in the form of a pop-up window or a communication message. When the flight application program pushes the flight information of the purchased air ticket, the terminal device can acquire the airplane departure time and the airplane landing time in the flight information of the purchased air ticket.

When an unexpected situation occurs on a flight for which an air ticket is purchased, such as an unexpected situation of an aircraft delay, a flight cancellation, etc., the flight application may also push flight dynamics information to facilitate the user's understanding of the flight dynamics. When the flight application pushes the flight dynamic information, the terminal device may acquire information about the aircraft departure time and the aircraft landing time in order to re-determine the aircraft departure time and the aircraft landing time.

Optionally, the terminal device may further obtain flight information in the sms application program, for assisting in determining the departure time and landing time of the aircraft.

For example, if the flight application has the capability to purchase tickets, the user may purchase tickets at the flight application. When the user purchases the air ticket by the flight application program, the user can input the mobile phone number, after the air ticket is successfully purchased, the short message application program of the mobile phone can receive the flight information of the purchased air ticket, and the terminal equipment can acquire the airplane take-off time and the airplane landing time from the short message application program. When unexpected situations occur on flights with purchased air tickets, the short message application program can also receive short message information, and the terminal equipment can acquire information related to the aircraft take-off time and the aircraft landing time from the short message information so as to determine the aircraft take-off time and the aircraft landing time again.

The terminal device may preset a short message template of the flight information, and when the short message application program receives the short message, the terminal device may match the short message template of the preset flight information with the received short message, and if the short message template of the preset flight information can be matched with the received short message, the terminal device may obtain the aircraft departure time and the aircraft landing time from the short message template.

The terminal equipment acquires the aircraft take-off time and the aircraft landing time from at least one channel, so that the missing of flight variation information can be prevented, and the aircraft take-off time and the aircraft landing time can be timely determined again.

S402, when the aircraft takes off, changing the network searching period into the aircraft flight time length, wherein the aircraft flight time length is calculated according to the aircraft take-off time and the aircraft landing time.

The aircraft flight duration may be referred to as a second network search period, which is not limited in this embodiment of the present application.

The aircraft take-off includes a state in which the aircraft is about to take-off, or is taking-off, or has taken-off.

It should be understood that the condition of the aircraft about to take off may refer to a condition in which the aircraft is taxiing on a runway in preparation for take off. The state in which the aircraft is taking off may refer to a state in which the aircraft is leaving the runway, but not all in the air. The already taken-off state may refer to a state in which the aircraft is entirely in the air.

The aircraft flight duration may be the aircraft landing time minus the aircraft takeoff time, wherein the aircraft landing time and the aircraft takeoff time may be times under the 24 hour rule.

Illustratively, from the flights of the Chengdu Chongqing, the flight with the take-off time of 13:27 and the landing time of 15:35 exists, and then the flight corresponding to the flight has the flight duration equal to the landing time (15:35) minus the take-off time (13:27), and the flight duration is 2 hours and zero 8 minutes.

The search for a network is an abbreviation for search for a network. When the terminal equipment is in the communication mode, the network can be searched periodically so as to be convenient for registering the network. The network searching period when the mobile phone is in the communication mode can be a default network searching period. The default network searching period may also be referred to as a first network searching period, which is not limited in this embodiment of the present application.

It should be noted that the terminal device searching network refers to a mobile communication network searching by the terminal device based on a subscriber identity module (subscriber identity module, SIM) card, for example, the terminal device searches for a network of a second generation mobile communication network (for example, a global system for mobile communication (global system for mobile communications, GSM)), a third generation mobile communication network (for example, a universal mobile communication system (universal mobile telecommunications system, UMTS)), a fourth generation mobile communication network (for example, a long term evolution (long term evolution, LTE) of the universal mobile communication system), a fifth generation mobile communication network (for example, a New Radio (NR)) and a possible evolution system in the future based on the SIM card.

When the aircraft takes off, the terminal equipment can change the network searching period into the aircraft flight duration, and in the aircraft flight period, network searching and network registering are not performed, so that the terminal equipment is prevented from searching a weak network signal in the high air to register the network, and a network injection suppressing mechanism is triggered.

It should be noted that, if the flight information of the purchased air ticket includes the flight time of the aircraft, the terminal device may obtain the flight time of the aircraft from the flight information of the purchased air ticket, without calculating according to the departure time and the landing time of the aircraft.

It should be noted that, when the aircraft takes off, the terminal device changes the network searching period to the aircraft flight duration, which is only one possible implementation manner. The terminal device can also receive the operation of modifying the network searching period by the user, and respond to the operation of modifying the network searching period by the user to change the network searching period into the network searching period modified by the user. The operation of modifying the network searching period by the user can be the operation of starting the flight mode by the user or the operation of shutting down by the user. The operation of modifying the network searching period by the user can also be the operation of triggering an option of changing the duration of the network searching period by the user. For example, the terminal equipment provides a man-machine interaction interface for the user, the man-machine interaction interface comprises an option for changing the duration of the network searching period, and the terminal equipment responds to the operation of the user triggering the option for changing the duration of the network searching period to change the network searching period into the network searching period modified by the user.

Alternatively, the terminal device may first determine whether the aircraft is taking off or about to take off, and the terminal device determines that the aircraft is taking off, there may be a plurality of possible implementations.

In one possible implementation, the terminal device may determine the aircraft takeoff based on the aircraft takeoff time.

For example, the terminal device may determine that the aircraft is flying when the aircraft takeoff time arrives.

In another possible implementation, the terminal device may determine the aircraft takeoff based on the aircraft takeoff time and the network status.

For example, when the aircraft is flying at high altitude, no network signal is provided, the network state is in an off state, and if the aircraft take-off time is reached and the network state is in the off state, the terminal device can determine that the aircraft takes off. For example, a telephone communication (Telephony) module in the application framework layer of the terminal device may be used to obtain the network status and send the network status, the terminal device may monitor the network connection status and the signal strength through a listen (new PhoneStateListener ()) function in a telephone communication management (Telephony manager) interface, and when the terminal device determines that the network status is in a disconnected state through the telephone communication management interface and the aircraft takeoff time arrives, the terminal device may determine that the aircraft has taken off.

In a further possible implementation, the terminal device determines the aircraft takeoff from the aircraft takeoff time and the geographical location information.

For example, if the aircraft departure time arrives and the geographic position information indicates that the current position of the terminal device is the departure place of the present flight, the terminal device may determine that the aircraft has taken off.

In another possible implementation, the terminal device determines the aircraft takeoff based on the aircraft takeoff time, the network status, and the geographic location information.

For example, if the aircraft departure time arrives, the network state is in a disconnected state, and the geographic location information indicates that the current location of the terminal device is the departure place of the present flight, the terminal device may determine that the aircraft has taken off.

S403, when the aircraft lands, changing the network searching period into a default network searching period, and starting network searching to register the network.

It should be noted that the aircraft landing includes a state in which the aircraft is about to land, the aircraft is landing, or the aircraft has landed.

It should be understood that the impending landing state of the aircraft may refer to a state in which the aircraft is about to drive into a runway in the air. The state in which the aircraft is landing may refer to a state in which the aircraft is driving into the runway, but not all of the aircraft is on the runway. The aircraft landing state may refer to a state in which the aircraft is all on a runway.

The default network searching period may also be referred to as a network searching period before modification or an original network searching period, which is not limited in the embodiment of the present application. The default network search period may be an existing network search period that implements network registration, e.g., a network search is performed every 30 seconds.

When the aircraft is determined to land, the aircraft falls to the ground, and at the moment, the mobile phone can detect a stronger network signal, can restore to the original network searching period, and performs network searching in the original network searching period so as to register a network.

Optionally, in a preset time before the aircraft lands, the terminal device may change the network searching period into a default network searching period and start network searching. For example, within 2 minutes before the aircraft lands, the terminal device may change the network searching period to a default network searching period and begin searching.

In the preset time before the aircraft lands, the mobile phone can detect a stronger network signal, at the moment, the network searching period can be changed into a default network searching period, and network searching begins, so that the network can be registered more quickly.

Optionally, when it is determined that the aircraft lands, the terminal device may change the network searching period to a network searching period shorter than the default network searching period, and start network searching, so that the terminal device registers the network quickly, and when the terminal device detects that the network state is a connection state, the network searching period shorter than the default network searching period is changed to the default network searching period.

Alternatively, the terminal device may first determine whether the aircraft is or is about to land. There are many possible implementations for the terminal device to determine that the aircraft is landing.

In one possible implementation, the terminal device may determine that the aircraft is landing based on the aircraft landing time.

For example, the terminal device may determine that the aircraft is landed when the aircraft landing time arrives.

In another possible implementation, the terminal device determines the aircraft takeoff based on the aircraft landing time and the geographic location information.

For example, if the aircraft landing time arrives and the geographic location information indicates that the current location of the terminal device is the destination of the present flight, the terminal device may determine that the aircraft is landing.

According to the network searching method, after the airplane takes off, the network searching period is changed into the airplane flight time, so that the terminal equipment can be prevented from searching the weak network signal in the high air to register the network, the network searching power consumption can be reduced due to triggering of the network injection inhibition mechanism, the network searching period is changed into the default network searching period after the airplane falls, the network searching is actively performed, the quick network registration is facilitated, and the network registering efficiency is improved.

As an optional embodiment, the method for determining the take-off of the aircraft may further include: the terminal device can determine the take-off time of the airplane according to the take-off time of the airplane and the acceleration and the speed of the terminal device.

The terminal device includes an acceleration sensor through which the acceleration can be acquired. The terminal device may determine the speed based on the change in location information and time. If the aircraft take-off time arrives, the acceleration is greater than or equal to a first preset threshold value, and the speed is greater than or equal to a second preset threshold value, the terminal device can determine that the aircraft is flying.

By way of example, FIG. 5 illustrates a schematic diagram of a method 500 of determining aircraft takeoff. As shown in fig. 5, the method 500 may include the steps of:

s501, acquiring the acceleration and the speed of the terminal equipment.

The terminal device may schedule the acceleration SENSOR (sensor_type_accelerome) through the SENSOR manager (SENSOR manager) and then acquire the acceleration of the terminal device in real time or periodically through the SENSOR event (SENSOR event). The terminal equipment can acquire the position information of the terminal equipment at a certain time point by a global positioning system (global positioning system, GPS), then establish the corresponding relation between the time point and the position information, and calculate the speed of the terminal equipment according to the change of the position information at two time points and the time difference of the two time points.

S502, if the aircraft take-off time arrives, judging whether the acceleration of the terminal equipment is larger than or equal to a first threshold value.

The aircraft takeoff time may be obtained through S401 described above. If the aircraft takeoff time is reached, the terminal device may execute S502, and if the aircraft takeoff time is not reached, the terminal device may determine whether the aircraft takeoff time is reached.

The first threshold is preset. For example, the first threshold may be 1 m/s ² (m/s ² )。

If the acceleration is greater than or equal to the first threshold, the terminal device may continue to execute S503, and if the acceleration is less than the first threshold, the terminal device may continue to execute S502 to continuously determine whether the acceleration is greater than or equal to the first threshold.

S503, if the acceleration is greater than or equal to the first threshold value, judging whether the speed is greater than or equal to the second threshold value.

The second threshold is preset. For example, the second threshold may be 150 kilometers per hour (km/h).

If the speed is greater than or equal to the second threshold, the terminal device may continue to execute S504, and if the speed is less than the second threshold, the terminal device may continue to execute S503 to continue to determine whether the speed is greater than or equal to the second threshold.

It should be noted that, the execution sequence of S503 and S504 is not limited, the terminal device may first determine whether the speed is greater than or equal to the second threshold, and if the speed is greater than or equal to the second threshold, the terminal device may determine whether the acceleration is greater than or equal to the first threshold.

S504, if the speed is greater than or equal to a second threshold value, determining that the aircraft takes off.

If the aircraft take-off time arrives, the acceleration is greater than or equal to a first preset threshold value, and the speed is greater than or equal to a second preset threshold value, the terminal device can determine that the aircraft takes off.

According to the method for determining the aircraft take-off, on the basis of arrival of the aircraft flight time, whether the aircraft takes-off can be judged in an auxiliary mode through acceleration and speed of the terminal equipment, whether the aircraft takes-off can be judged more accurately, and accuracy of aircraft flight detection is improved.

It should be noted that, if the aircraft take-off time arrives, the terminal device may change the network searching period into the aircraft flight duration, otherwise, if the aircraft take-off time arrives and at least one of the following conditions is satisfied, the terminal device may change the network searching period into the aircraft flight duration:

1) The geographic position indicates that the current position of the terminal equipment is the departure place of the flight;

2) The network state is the disconnected state;

3) The acceleration of the terminal device is greater than or equal to a first preset threshold value and the speed of the terminal device is greater than or equal to a second preset threshold value.

It should be understood that the terminal device may determine that the aircraft takes off according to at least one of the above conditions, and change the network searching period to the aircraft flight duration.

As an alternative embodiment, the terminal device may switch on the flight mode when the terminal device determines that the aircraft is taking off. It will be appreciated that both the long-range communication transmission network and the short-range transmission network of the terminal device are switched off when the terminal device is in the flight mode.

When the terminal equipment is in the flight mode, network searching and network registering are not performed, so that the power consumption can be reduced, and the situation that network registering is performed by searching a weak network signal in the high air, so that a network injection suppressing mechanism is triggered can be prevented. When the terminal equipment determines that the aircraft falls to the ground, the flight mode can be closed, the terminal equipment can search the network and register the network, so that the quick network registration is facilitated, and the network registration efficiency is improved.

It should be noted that, the terminal device may start to take effect after the user authorization by turning on or off the function of the flight mode.

The terminal device may be a mobile phone, and the "setting" interface of the mobile phone may add an authorized option, and when receiving an operation of selecting the authorized option by the user, the mobile phone responds to the operation, and has a function of turning on or off the flight mode.

As an alternative embodiment, the terminal device may shut down the mobile network after the terminal device determines that the aircraft is taking off. The mobile network is a mode that the terminal equipment is connected to the public network to realize an internet method.

When the terminal equipment is in the flight mode, the connection of the mobile network is not performed, and the power consumption can be reduced. After the terminal equipment determines that the aircraft falls to the ground, the mobile network can be started to start connecting with the network, thereby being beneficial to quickly registering the network and improving the efficiency of registering the network.

In another possible implementation, the flight detection service module may send the aircraft departure time and the aircraft landing time to the aircraft state detection module by a cross-process interface call.

S603, if the aircraft state detection module determines that the aircraft takes off, sending first indication information to the network searching service module, wherein the first indication information is used for indicating the network searching service module to change the network searching period into the aircraft flight time, the aircraft flight time is calculated according to the aircraft take-off time and the aircraft landing time, and correspondingly, the network searching service module receives the first indication information.

The aircraft state detection module may determine whether the aircraft is taking off based on the aircraft take-off time. In order to ensure the accuracy of the detection of the aircraft state detection module, the aircraft state detection module may also assist in determining according to at least one of the network state, the geographical location information, and the acceleration and speed of the terminal device.

The aircraft state detection module can calculate the aircraft flight duration according to the aircraft take-off time and the aircraft landing time. If the aircraft state detection module determines that the aircraft takes off, the first indication information can be sent to the network searching service module.

S604, the network searching service module changes the network searching period into the flight duration of the airplane according to the first indication information, and a new network searching period is obtained.

And the network searching service module determines the network searching period as a new network searching period according to the first indication information, wherein the duration of the new network searching period is the flight duration of the airplane.

S605, the network searching service module sends a new network searching period to the modem, and correspondingly, the modem receives the new network searching period.

Illustratively, the network searching service module may transfer the new network searching period to the modem module by calling an upper layer (radio interface layer, RIL) interface (setnetsearch period), and the modem module may update the network searching period to the new network searching period.

S606, the modem module performs network searching according to the new network searching period.

S607, if the aircraft state detection module determines that the aircraft falls to the ground, sending second indication information to the network searching service module, where the second indication information is used to instruct the network searching service module to change the network searching period into a default network searching period.

The aircraft state detection module may determine whether the aircraft is landed based on the aircraft landing time. In order to ensure the accuracy of the detection of the aircraft state detection module, the aircraft state detection module can also assist in judgment according to the geographic position information.

If the aircraft state detection module determines that the aircraft falls to the ground, the second indication information can be sent to the network searching service module.

And S608, the network searching service module changes the network searching period into a default network searching period according to the second indication information.

The network searching period is a new network searching period, and the network searching service module can determine the new network searching period as a default network searching period according to the second indication information.

S609, the network searching service module sends a default network searching period to the modem module, and correspondingly, the modem module receives the default network searching period.
