DCH channels refer to the dedicated channel that common channel individually marks off, and ensure security of the information in wireless network transmissions.
The digital signal modulated that Modem is used to transmit separates data signal on carrier wave or from carrier wave.
It should be noted that above-mentioned complete the process interacted between terminal device and base station, but terminal device receives
After the incoming telephone signal sent to base station, also need to identify that the incoming telephone signal could be completed to detect the process of triggering alarm event.Show
Example property, Modem (modem) of the base station into containing specific SIM card terminal device sends the instruction of incoming telephone signal, when
Network state is changed after terminal device Modem receives the instruction, and the network change information is passed through into CP
(Communication Processor, Communication processor) layer is uploaded to RIL (Radio Interface Layer, radio
Interface layer) layer, detection triggering alarm event is completed by RIL layers, such as uploads RIL_UNSOL_CALL_RING to RIL layers.Wherein,
RIL layers can realize the request received with sending communication request to CP layers, and including RILD layers and RILJ layers.Wherein, RILD layers
For C++ layers, the request for RILJ layers to be sended over continues to be transferred to CP layers, and in time sends the state change of CP layers
To RILJ layers；RILJ layers are Java layers, for providing general API (Application Programming for upper strata
Interface, application programming interface) interface, and maintain with the communication of RILD layers, and by the request on upper strata send to
RILD layers.More specifically, RILC layers receive the network change information of CP intermediate layers transmission, and will by way of socket
The network change information transmission receives the Data Concurrent read by the RILReceiver in RILJ layers and delivers to upper strata to RILJ layers
Handlemessage.When Handlemessage monitors that triggering alarm event arrives, call function driving incoming call jingle bell behaviour
Make to operate with caller identification.
It should be noted that the method that the present embodiment provides monitors that triggering alarm event arrives in Handlemessage
When, function drive incoming call jingle bell operation is not directly invoked to be operated with caller identification, but drives terminal equipment transmitting ultrasonic wave
Signal.Specifically, the device of terminal device transmitting ultrasonic signal can be existing device in terminal device, such as loudspeaker,
It can be the ultrasonic transmitter of specific installation.Exemplary, launch ultrasonic signal using the loudspeaker in terminal device, when
After the instruction for receiving transmitting ultrasonic signal, the instruction is converted into audio signal by Handle by electro-acoustic element, and by
Input is to loudspeaker after audio amplifier amplification, oscillator produce the operation such as high-frequency oscillation signal, to realize ultrasonic signal
Operation.It should be noted that the present embodiment includes but does not limit the mode of terminal device transmitting ultrasonic signal.
It should be noted that the present embodiment after triggering the call signal received in alarm event only to playing incoming ring tone
The process of (i.e. calling event) volume adjusting is discussed in detail, and the sound of the ringing sound of text message of terminal device and quarter-bell the tinkle of bells
Amount regulation launches ultrasonic wave letter as the process of above-mentioned calling event volume adjusting when triggering alarm event is detected
Number.
Exemplary, the ultrasonic signal of terminal device transmitting can have polytype.As terminal device can launch one
Secondary ultrasonic signal, repeated ultrasonic ripple signal can also be launched, and the signal intensity for launching repeated ultrasonic ripple signal can be identical
Can be different.It should be noted that transmitting species of the embodiment of the present invention not to ultrasonic signal is defined.
Step 120, obtain target feedback signal corresponding to the ultrasonic signal, the letter according to the target feedback signal
Number intensity judges whether terminal device is in confined space.
Exemplary, target feedback signal refers to that what is received after terminal device transmitting ultrasonic signal corresponds
Signal, the beam ultrasonic signal that specially terminal device receives run into after the barriers such as clothing/bag inwall reflect
Signal.Signal intensity refers to intensity of acoustic wave (sound intensity), refers specifically in the unit interval by perpendicular to Acoustic Wave Propagation direction
The energy of unit area, determined by the size of Oscillation Amplitude.Confined space refers to the environment of sealing and occlusion, in the present embodiment
Terminal device is referred mainly to be in pocket, various types of handbag or be covered by the environment such as covering.
Exemplary, the device that terminal device obtains target feedback signal can also be by existing device in terminal device
(such as microphone) is gathered, or the ultrasonic receiver of specific installation is acquired.If terminal device is in confined space,
The target feedback signal then got is stronger, if terminal device is not in confined space, the target feedback signal that obtains
Signal intensity is 0 or weaker.Exemplary, the microphone collection target feedback signal in terminal device, it can be set using terminal
Standby internal AudioRecord, MediaRecorder or built-in application program are acquired, and are returned by analyzing target
Feedback signal obtains signal intensity.Terminal device can be determined when the signal intensity of target feedback signal is more than preset signal strength
In confined space.
It should be noted that generally terminal device is not in obtaining fall short feedback signal during confined space, but this
Embodiment is prevents terminal device from causing to miss with receiving faint target feedback signal when wall or article closer to the distance
Sentence, therefore the present embodiment provides preset signal strength to prevent this kind of situation.
Step 130, if so, then increase it is described triggering alarm event ringing volume.
Due to the application scenarios of the present embodiment are in clothes pocket for terminal device, in various types of bag or covering
Under, therefore, for terminal device if it is determined that being in confined space, then increase triggers the ringing volume of alarm event.Exemplary, triggering
The increase of alarm event ringing volume can be default fixed value in terminal device, or work as front ring according to terminal device
Dynamic value depending on border.Also, after it is determined that terminal device is in confined space, the RIL layers in terminal device call the tinkle of bells sound
Amount increase function and broadcasting the tinkle of bells one thread of function creation go to increase ringing volume and play the tinkle of bells.
Exemplary, the emitter using the loudspeaker of terminal device as ultrasonic signal, and microphone is as super
The reception device of acoustic signals.Figure 1B is the structural representation of a kind of terminal device loudspeaker and microphone.As shown in Figure 1B, scheme
Mark 10 is loudspeaker, and icon 20 is microphone.Exemplary, after triggering alarm event is detected, loudspeaker 10 launches ultrasound
Ripple signal, and target feedback signal is gathered by microphone 20, judge that terminal is by the signal intensity according to target feedback signal
It is no to be in confined space.It should be noted that loudspeaker 10 may be contained within bottom with microphone 20, it is mostly attractive in appearance, therefore raise one's voice
Device 10 may also set up the other positions in terminal device with microphone 20, and the present invention is defined not to this.
It should be noted that the emitter of ultrasonic signal can be one or more with reception device, and it is dispersible
In the diverse location of terminal device (such as front, the back side, side and bottom).Especially need to launch repeated ultrasonic ripple signal
When, multiple emitters can be used with multiple reception devices judge the current state of terminal device.
The volume adjusting method provided in the embodiment of the present invention, by the way that when detecting triggering alarm event, transmitting is ultrasonic
Ripple signal, target feedback signal corresponding to the ultrasonic signal is obtained, the signal intensity according to the target feedback signal is sentenced
Whether disconnected terminal device is in confined space, if so, then increasing the ringing volume of the triggering alarm event, the present invention is due to being
Terminal device launches ultrasonic signal, and unitized processing is carried out to sound source, is avoided because sound source otherness causes to judge terminal
The problem of whether equipment is in confined space inaccuracy, not only increases the flexibility of volume adjusting, also improves volume adjusting
Accuracy.
Optionally, after the ringing volume of the increase triggering alarm event, in addition to：If detect the end
The position of end equipment changes and the signal intensity of the target feedback signal is less than the 3rd preset strength, then recovers described and touch
Send out the initial ringing volume of alarm event.
It is exemplary, initial ringing volume refer to terminal device do not increase ringing volume before original ringing volume.
3rd preset strength is used to judge whether terminal device is taken out confined space, due to when terminal device is taken out confined space not
It is wrapped, therefore the setting of its value is almost zero.In the present embodiment, the position of terminal device, which changes, refers to terminal device
Due to being taken out and caused change in location by user.When the position for detecting terminal device changes, target feedback signal
Signal intensity should also change and be less than the 3rd preset strength, determined if above-mentioned condition is satisfied by terminal device by by
Go out, recover the initial ringing volume of triggering alarm event immediately.It should be noted that the change in location of terminal device can pass through
The sensor such as gravity sensor or acceleration transducer is detected, and the initial ringing volume for recovering triggering alarm event then needs
The RIL layer call functions in terminal device bottom are wanted to be realized.
In the present embodiment, by the change in location and the signal intensity of target feedback signal of detection terminal equipment, with prison
The time for being taken out confined space is surveyed, so as to recover initial ringing volume in time, avoids the ringing volume mistake after increase
Interfere with other people greatly.
Fig. 2 is the schematic flow sheet of another volume adjusting method provided in an embodiment of the present invention, and this method includes as follows
Step：
Step 210, when detect triggering alarm event when, repeatedly launch identical ultrasonic signal.
Exemplary, when terminal device is put into by user is walked in clothes pocket/bag, terminal device is not constantly in
Inactive state, the distance between terminal device and clothes pocket/bag inwall is caused to change, therefore by repeatedly launching
It is more accurate whether identical ultrasonic signal is judged in confined space terminal device.Wherein, identical ultrasonic wave
Signal refers to frequency, amplitude and the energy all same of ultrasonic signal.
The average signal strength of feedback signal is as institute corresponding to step 220, the ultrasonic signal for repeatedly launching acquisition
The signal intensity of target feedback signal is stated, and judges whether terminal device is according to the signal intensity of the target feedback signal
Confined space.
Exemplary, due to the ultrasonic signal and non-once of transmitting, it is therefore desirable to receive the transmitting of repeated ultrasonic ripple signal
The feedback signal of inwall reflection is run into afterwards, and counts letter of the average signal strength of multiple feedback signal as target feedback signal
Number intensity.
Step 230, if so, then increase it is described triggering alarm event ringing volume.
Exemplary, prefixed time interval is needed between transmitting identical ultrasonic signal to ensure that the feedback received is believed
Interference will not be produced between number.For example, if prefixed time interval is 10ms, then is spaced after the first beam ultrasonic signal of transmitting
10ms, then launch the second beam ultrasonic signal.Also, the present embodiment is not construed as limiting to the number for launching ultrasonic signal.
The volume adjusting method provided in the embodiment of the present invention, when triggering alarm event by detecting, repeatedly launch phase
Same ultrasonic signal, the average signal strength of feedback signal is as target corresponding to the ultrasonic signal that acquisition is repeatedly launched
The signal intensity of feedback signal to judge whether terminal device is in confined space, by detecting repeated ultrasonic ripple believed by the present embodiment
Number feedback signal, take its average value, effectively prevent because of situations such as the single ultrasonic signal that motion causes to detect
The weaker situation of feedback signal, the accuracy for judging whether terminal device is in confined space is improved, adjusted so as to improve volume
The accuracy of section.
Fig. 3 is the schematic flow sheet of another volume adjusting method provided in an embodiment of the present invention, and this method includes as follows
Step：
Step 310, when detect triggering alarm event when, launch the first ultrasonic signal.
It should be noted that the signal intensity that the space size of confined space obtains target feedback signal to terminal device has
Have a significant impact.For example, terminal device, which is respectively placed in clothes pocket and is positioned over bag, (inside sets space than pocket space
When greatly) interior, the signal intensity of acquired target feedback signal is different, usual clothing after transmitting identical ultrasonic signal
Pocket due to narrow space, believe by the target feedback that the signal intensity ratio for the target feedback signal that terminal device receives is in bag
Number signal intensity it is stronger.
Because the signal intensity of the ultrasonic signal suitable for launching in clothes pocket scene is not necessarily suitable bag, cause
The current state of erroneous judgement terminal device is not in confined space.The first ultrasonic signal in the present embodiment also refers to fit
Clothes pocket is in for terminal device or includes the scene of stock size bag, specifically, terminal device detects that triggering rings
During bell event, launch the first ultrasonic signal.
If the signal intensity of feedback signal corresponding to step 320, first ultrasonic signal got is less than first
Preset strength, then launch the second ultrasonic signal, by the letter of feedback signal corresponding to second ultrasonic signal got
Number signal intensity of the intensity as target feedback signal.
Wherein, the signal intensity of second ultrasonic signal is more than the signal intensity of first ultrasonic signal, with
Make the signal of feedback signal corresponding to second ultrasonic signal that when the confined space is more than pre-set space, gets
Intensity is more than the first preset strength.
Exemplary, the first preset strength is to be in clothes pocket suitable for terminal device or include stock size bag
Under scene, the signal intensity of the corresponding target feedback signal got after terminal device transmitting ultrasonic signal, preset
Space is also the space size set under this kind of scene.The signal intensity of second ultrasonic signal and the first ultrasonic signal
Sender unit is identical, and the signal intensity of the second ultrasonic signal is more than the signal intensity of the first ultrasonic signal.
Exemplary, the target feedback signal for causing terminal device to receive in order to avoid confined space is excessive is too small, this
Embodiment setting signal intensity second ultrasonic signal more stronger than the first ultrasonic signal strength.When the first ultrasound got
When the signal intensity of feedback signal corresponding to ripple signal is less than the first preset strength, stronger the second ultrasonic wave letter of transmission signal
Number, and the signal intensity of target feedback signal is set as to the signal intensity of feedback signal corresponding to the second ultrasonic signal.
Step 330, if so, then increase it is described triggering alarm event ringing volume.
It should be noted that the present embodiment is only more than the first ultrasonic signal to the signal intensity of the second ultrasonic signal
Signal intensity is defined, and its difference in signal strength is not defined.
The volume adjusting method provided in the embodiment of the present invention, if detecting feedback signal corresponding to the first ultrasonic signal
Signal intensity be less than the first preset strength, the second stronger ultrasonic signal of transmission signal intensity, and being believed with the second ultrasonic wave
Signal intensity of the signal intensity of feedback signal corresponding to number as target feedback signal, the present embodiment pass through transmission signal intensity
Different ultrasonic signals, avoid the excessive feelings for causing to judge whether terminal device is in confined space inaccuracy of confined space
Condition, improve the accuracy of volume adjusting.
Fig. 4 is the schematic flow sheet of another volume adjusting method provided in an embodiment of the present invention, and this method includes as follows
Step：
Step 410, when detect triggering alarm event when, launch ultrasonic signal.
Step 420, target feedback signal corresponding to the ultrasonic signal is obtained, if the signal of the target feedback signal
Intensity is less than the second preset strength, then the range information and gravity sensitive obtained according to the range sensor of the terminal device
The orientation information that device obtains, judges whether the terminal device is in semi-enclosed space.
It should be noted that terminal device habitually can be put into clothing mouth by generally user in a manner of head is downward
In bag/bag, if clothes pocket/bag can not it is fully wrapped around live terminal device, namely terminal device is not in complete confined space
When, because terminal device is generally in bottom emission and received ultrasonic signal, therefore cause the ultrasonic signal of transmitting due to non-
Confined space and fully reflective/most of can not be reflected as target feedback signal, and then the target for causing terminal device to obtain
The signal intensity of feedback signal is weaker.
Exemplary, the second preset strength is to be in the not fully wrapped around firmly terminal of clothes pocket/bag suitable for terminal device
Under the scene of equipment, the signal of the corresponding target feedback signal got after terminal device transmitting ultrasonic signal is strong
Degree.Range sensor is located at around the receiver of mobile phone front, nearby whether has object for detection terminal equipment front, is specially profit
Launch infrared ray with infrared LED (Light Emitting Diode, light emitting diode) lamp, after being reflected by closer object, lead to
The strength detection distance for receiving infrared ray is crossed, it is general to determine within 10cm distances.Range information is to be examined by range sensor
The distance between the terminal device front measured and close thing.Gravity sensor is to measure internal one default thing using piezo-electric effect
Body, using the component size of gravity orthogonal vertical and horizontal both direction as position data, whether to judge terminal device head
Downwards.Orientation information refers to the direction at terminal device current time, is put downwards or vertically as terminal device is disposed vertically head
Head is put to first-class.
Exemplary, because range sensor can only detect whether object, it can not but judge whether the object is clothing
Pocket/bag inwall, it is therefore desirable to reference to the orientation information of gravity sensor detection terminal equipment, if terminal device be collected into away from
The data obtained from sensor and gravity sensor meet the state that terminal device is in clothes pocket/bag, now, if obtaining
The signal intensity for the target feedback signal got is less than the second preset strength, then can determine that terminal device is in semi-hermetic sky
Between.
Step 430, if so, then increase it is described triggering alarm event ringing volume.
It should be noted that in the present embodiment, semi-enclosed space refers to that terminal device head is lowered into clothing mouth
In bag/bag, due to not completely enclosing, portion of ultrasonic sound wave signal is caused to reflex to the particular space in the external world.Even at this
In semi-enclosed space, terminal device can also slacken ringing volume, therefore need also exist for the ringing volume of increase triggering alarm event.
The volume adjusting method provided in the embodiment of the present invention, by combine range sensor obtain range information and
The orientation information that gravity sensor obtains judges whether to be in semi-enclosed space, the scene for causing ringing volume reduction is carried out
Supplement, equally improve the accuracy of volume adjusting.
Fig. 5 is the schematic flow sheet of another volume adjusting method provided in an embodiment of the present invention, and this method includes as follows
Step：
Step 510, when detect triggering alarm event when, launch ultrasonic signal.
Step 520, obtain target feedback signal corresponding to the ultrasonic signal, the letter according to the target feedback signal
Number intensity judges whether terminal device is in confined space.
Step 530, default ringing volume increase grade.
Exemplary, ringing volume increase grade can set multiple gears, and each gear sets different increase grades,
Such as increase the volume of initial ringing volume 20%, 40% or 50%, specific increment value can be set as system default value, also may be used
To be set according to user's request.Exemplary, ringing volume increase grade can making an uproar according to terminal device current environment
Value is set, and each grade corresponds to the scope of one section of level of noise, the decibel value as corresponding to increasing initial ringing volume 20%
For 50dB-80dB, it is 130dB-160dB to increase decibel value corresponding to initial ringing volume 50%.If specifically for example, terminal device
Current environment is more noisy, and the level of noise of detection is 150dB, then increases initial ringing volume 50%；If terminal device works as front ring
Border is more quiet, and the level of noise of detection is 50dB, then increases initial ringing volume 20%.
The level of noise of step 540, the detection terminal device current environment, the tinkle of bells sound is determined according to the level of noise
Amount increase grade.
Exemplary, level of noise refers to weighing the strong and weak numerical value of noise.Terminal device detects the level of noise of current environment
It can be detected by application software/noise detection device of installation etc..Specifically, after triggering alarm event is detected,
Not only launch ultrasonic signal, also detection terminal equipment current environment level of noise, by the level of noise of current environment with it is default
The corresponding decibel value of ringing volume increase grade is compared to determine to need the tinkle of bells increased under terminal device current environment
Level of sound volume.
Step 550, increase the grade increase ringing volume for triggering alarm event according to the ringing volume.
Exemplary, after determining that ringing volume increases grade, the RIL in terminal device bottom is notified according to the grade
Layer calls respective function to be realized.
If step 560, the terminal device is not detected by touch control operation of the user to touch-screen in preset duration, increase
Add the ringing volume increase grade, and the triggering alarm event is increased according to the ringing volume increase grade after increase
Ringing volume.
Exemplary, when terminal device is in the ringing volume of increase triggering alarm event in confined space, it is possible to
Because factor causes user still not to be noted farther out etc. by the noisy degree of current environment or the distance between user and terminal device
Trigger alarm event.Therefore, the present embodiment setting preset duration is used for the ring time of monitoring terminal equipment.Wherein, when presetting
The long dynamic value that equally can be set as the default value of terminal device or adjusted according to user's request.Touch-screen is that one kind can
The induction type liquid crystal display device of the input signals such as contact is received, when contacting the graphic button on screen, touching on screen
Feel that reponse system can drive various link devices according to the formula of preprogramming, be substituted for mechanical push button panel, and
Lively visual and sound effects are produced by liquid crystal display picture.
Exemplary, terminal device is by monitoring whether have Touch events to judge whether user touches to terminal device
Screen is touched to be operated.For example, Touch events can be touchstart (being triggered when finger is put on screen) or
Touchmove (finger slidingtype on screen triggers) etc..If in preset duration, terminal device is not detected by user to touching
The touch control operation of screen is touched, then increases ringing volume increase grade, and end is reinformed according to the ringing volume increase grade after increase
RIL layers in end equipment bottom call respective function with the ringing volume of further increase triggering alarm event.For example, terminal is set
It is standby initially to increase initial ringing volume 20%, if in preset duration, and be not detected by the operation of terminal device, then will be initial
Increase initial ringing volume 20% to be adjusted to increase initial ringing volume 40%.
