Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
An embodiment of the present application provides a signal control method, which is applied to an electronic device and is shown in fig. 1, and the method includes the following steps:
The radiation signal is used for establishing communication connection with a base station; the target radio frequency power is equal to the maximum transmission power upper limit allowed by the communication unit when the electronic equipment is in a weak signal environment, so that the quality of a radiation signal is improved.
In the embodiment of the present application, the electronic device is a device having a communication function and a positioning function, and may be a mobile terminal device, for example, a mobile phone device, a telephone watch, and the like. The distress mode may be an operational mode in which the electronic device is capable of signaling an emergency distress. The communication unit of the electronic device may be a Modem (Modem), and the antenna of the corresponding electronic device is connected to the communication unit, and is configured to send a radiation signal transmitted by the Modem, or send the radiation signal to the Modem after receiving the radiation signal of the base station, and perform analysis processing. The target rf power is the operating power of the communication unit when the electronic device removes the limitation of the Specific Absorption Rate (SAR). The target radio frequency power is greater than the SAR maximum limit power.
The electronic equipment is in a help seeking mode, which can be realized by controlling the working mode of the electronic equipment to be switched to the help seeking mode after a user performs corresponding operation on the electronic equipment when the user of the electronic equipment is in an emergency environment; the method can also be realized by automatically switching to the help-seeking mode when the electronic equipment determines that the environmental parameters of the current environment of the user are matched with the preset environmental parameters needing to enter the help-seeking mode after detecting the environmental parameters of the current environment of the user, or by generating prompt information for judging whether to enter the help-seeking mode and enabling the user to enter the help-seeking mode according to the prompt information.
And 102, if the communication connection between the electronic equipment and the base station is successfully established, executing the help-seeking operation corresponding to the help-seeking mode.
In the embodiment of the application, when the communication unit of the electronic device operates at the target radio frequency power and establishes a communication connection with the base station, the electronic device may automatically send information including position information to the emergency rescue platform and/or automatically dial an emergency rescue call and other distress operations. Therefore, the radio frequency power of the search signal of the electronic equipment is enhanced, the signal retrieval capability of the electronic equipment when the signal is weak is effectively improved, the user can send out distress information to obtain faster rescue, and the occurrence probability that the user cannot obtain faster emergency rescue due to the fact that the signal retrieval capability of the electronic equipment is weak is reduced.
The embodiment of the application provides a signal control method, wherein if an electronic device is in a distress mode, a communication unit of the electronic device operates based on target radio frequency power of a distress scene to send/receive radiation signals through an antenna of the electronic device, and if the electronic device is successfully in communication connection with a base station, a distress operation corresponding to the distress mode is executed. Therefore, in the help seeking mode, the communication unit of the electronic equipment is controlled to operate at the target radio frequency power equal to the maximum transmission power upper limit allowed by the communication unit when the electronic equipment is in a weak signal environment, the problem that the electronic equipment cannot seek rescue through the electronic equipment under the condition that the electronic equipment cannot detect or the detected mobile communication network signal is weak at present is solved, the method for seeking rescue through the electronic equipment is realized, and the intelligent degree of the electronic equipment is effectively improved.
Based on the foregoing embodiments, an embodiment of the present application provides a signal control method, where the method is applied to an electronic device, and the method includes the following steps:
The radiation signal is used for establishing communication connection with a base station; the target radio frequency power is equal to the maximum transmission power upper limit allowed by the communication unit when the electronic equipment is in a weak signal environment, so that the quality of a radiation signal is improved.
In the embodiment of the application, the radiation signal is generally a mobile network communication signal provided by each mobile communication network operator which can be supported by the electronic device, that is, in the distress mode, the electronic device searches any mobile communication network signal supported by the electronic device with the target radio frequency power, so that the distress operation corresponding to the distress mode can be executed, and in the process of performing the distress operation, the authentication process with the searched mobile communication network information is not needed, so that the communication efficiency is improved, the rescue request information is sent out as soon as possible, and the health and safety of the user are ensured. Taking the example that the electronic device enters the distress mode as a user and manually switches the working mode of the electronic device according to actual conditions, the electronic device controls the electronic device communication unit to operate at a target radio frequency power corresponding to a distress scene, and then can send/receive a radiation signal through an antenna of the electronic device.
In some application scenarios, before the electronic device performs step 201, the electronic device may be further configured to perform the following steps: if the electronic equipment is detected to be in the early warning area, detecting a radiation signal which can be received by the electronic equipment according to a preset time interval; if the electronic equipment is detected to reach the covering edge position of the radiation signal, storing the covering edge position; generating first prompt information for prompting a user to enter a no-signal area; and displaying the first prompt message. The early warning area can be some preset dangerous areas. In some application scenarios, when the electronic device is detected to be in the early warning area, the detection may be performed when the electronic device is in a field motion mode. Therefore, the user can be warned, and the user is prevented from entering a dangerous area to cause inevitable loss.
After the electronic device executes step 201, as shown in fig. 2, step 202 and step 204 may be selectively executed, or as shown in fig. 3, steps 203 to 204 may be selectively executed.
In the embodiment of the present application, the head-hand scene refers to a hand-holding scene in which a user holds the electronic device and a head scene in which the user places the electronic device beside the ear of the user. After the electronic equipment enters the distress mode, different radio frequency powers can be set for different scenes, and different priorities are set for the different scenes, so that the target radio frequency power of the distress scene is set to be the highest priority, namely when the communication unit of the electronic equipment runs at the target radio frequency power of the distress scene, no matter the electronic equipment detects any other scene except the distress scene, the radio frequency transmitting power of the communication unit cannot be adjusted, namely, when the electronic equipment detects any other scene except the distress scene, the upper limit of the radio frequency transmitting power of the communication unit of the electronic equipment does not reach the target radio frequency transmitting power. I.e. once the electronic device is in a distress scenario, the maximum value of the transmission power of the communication unit is set to the maximum transmission power allowed by the communication unit, i.e. is no longer limited.
For example, a high to low priority list may be as follows:
| application scenarios | Upper limit of radio frequency transmission power |
| Scene of asking for help | Target radio frequency power |
| Hand-held scene | First limit power |
| Head scene | Second limit power |
In the table, the first limit power and the second limit power are both smaller than the maximum transmission power upper limit allowed by the communication unit, and the first limit power is larger than the second limit power. The target radio frequency power of the distress scene is equal to the maximum transmitting power upper limit allowed by the communication unit.
And 203, if the output parameters sensed by the electronic equipment meet the SAR scene, the communication unit prohibits switching to the SAR scene.
In the embodiment of the application, the priority of the frequency of each scene is not set in the electronic device, but when the electronic device is in the distress mode, if the electronic device detects output parameters of other scenes except the distress scene, that is, when the electronic device detects that the electronic device is in the SAR scene, the operating frequency of the communication unit is controlled not to be changed, and the target radio frequency power is still kept to operate, so that the communication unit is prohibited from being switched to the SAR scene.
For example, when the electronic device currently enters the distress mode and the communication unit operates at the target radio frequency power, and the electronic device detects that the electronic device is in a user holding scene or a head scene where the electronic device is located near the ears of the user, the operating frequency of the electronic device is not switched, so that the electronic device still operates at the target radio frequency power, and the capability of the electronic device in searching for a radiation signal is improved.
And step 204, if the communication connection between the electronic equipment and the base station is successfully established, executing the help-seeking operation corresponding to the help-seeking mode.
In the embodiment of the present application, the base station may be a device for providing any mobile communication network supported by the electronic device, and preferably may be a device for providing a mobile communication network corresponding to a Subscriber Identity Module (SIM) card installed in the electronic device. When a communication unit of the electronic equipment retrieves the base station by using the target radio frequency power, the electronic equipment can send the collected current position information and the collected help seeking information to a rescue platform, or the electronic equipment automatically dials an emergency rescue telephone number so that a user can quickly seek rescue help.
In some application scenarios, the implementation process of performing the distress operation in the distress mode may be implemented by referring to the following steps: acquiring the current position of the electronic equipment; acquiring user information corresponding to the electronic equipment; generating help-seeking information based on the current position and the user information; sending distress information to target communication equipment corresponding to a preset emergency communication identifier; the distress message is used for indicating the user information and the second current position, and the distress operation comprises an operation of sending the distress message. The user information at least comprises name information of the user, and further comprises image information with face information of the user, wherein the image information is preferably a whole body image of current dressing information with the face information of the user. The preset emergency communication identifier may be an emergency rescue telephone number. Therefore, the user information and the current position of the user are sent to the target communication equipment, so that rescue workers can know the characteristics of the user, the user is quickly positioned in the rescue process, the rescue is implemented, and the rescue efficiency is improved.
In some application scenarios, the implementation process of performing the distress operation in the distress mode may be further implemented with reference to the following steps: determining a preset emergency communication identifier; sending a communication request to target communication equipment corresponding to a preset emergency communication identifier; the communication request is used for requesting to establish a communication link with the target communication equipment to realize voice communication, and the help seeking operation comprises an operation of sending the communication request. Therefore, the rescue is requested in a mode of dialing the telephone, and the help seeking efficiency is improved.
Based on the foregoing embodiment, in other embodiments of the present application, as shown in fig. 4 or fig. 5, before the electronic device performs step 204, it may further select to perform step 205:
and step 205, if the electronic equipment and the base station do not successfully establish communication connection, outputting position prompt information.
The position prompt information is used for prompting the edge position covered by the network signal, and the edge position is the position information of the weakest network signal recorded in the moving process of the electronic equipment.
In this embodiment of the application, when the electronic device and the base station do not establish a communication connection successfully, that is, when a communication unit of the electronic device operates at a target radio frequency power and a radiation signal that can be used for performing a distress operation is not searched yet, the electronic device generates position prompt information according to the weakest position information of a network signal recorded in a moving process, and prompts an edge position covered by the network signal, so that a user can know the edge position covered by the network signal, and can move to the edge position prompted by the position prompt information, for example, return to the original route, so that the electronic device can establish a communication connection with the base station quickly, and implement a distress operation corresponding to a distress mode.
Further, the position prompt message may prompt the distance and/or the required time when the user returns to the edge position in addition to the edge position.
Based on the foregoing embodiments, in other embodiments of the present application, referring to fig. 6 or fig. 7, after the electronic device performs step 205, the electronic device may further be configured to perform steps 206 to 207:
and step 206, generating a navigation path based on the position prompt information.
In this embodiment, the electronic device may further determine the navigation path based on the edge position in the position prompt information and the current position of the electronic device. The navigation path may be a historical path recorded by the electronic device itself when the navigation path reaches the current position of the electronic device from the edge position, or the navigation path may be an optimal path from the current position of the electronic device to the edge position by the electronic device, where the optimal path may be implemented according to an offline map cached in the electronic device, and since the electronic device is in a signal-free area, a Global Positioning System (GPS) may not be used, and the current position of the electronic device may not be accurately acquired, and therefore, a certain check may be performed on the current position.
And step 207, executing the 'operation of the communication unit of the electronic equipment based on the target radio frequency power of the distress scene' in a process cycle based on the navigation path navigation until the communication connection between the electronic equipment and the base station is successful.
In the embodiment of the application, in the process that the user moves according to the navigation path, the electronic device still searches the radiation signal of the base station with the target radio frequency power according to a certain scanning period until the electronic device searches the radiation signal of the base station, and the electronic device is in communication connection with the base station, so that the help-seeking operation in the help-seeking mode is realized.
In some application scenarios, when a communication unit of the electronic device operates based on a target radio frequency power of a distress scenario, a radiation signal of a base station may be searched according to a certain preset period. Further, when the preset period is determined, the remaining power of the electronic device may be considered, and the specific method may be implemented by the following steps: determining the current remaining capacity of the electronic equipment; determining a search period for searching the radiation signal based on the target radio frequency power by adopting the communication unit based on the current residual electric quantity; the radiation signal is searched for by the communication unit according to the search period. If the current remaining power of the electronic device is greater than the preset remaining power threshold, the search period of the electronic device may be shortened, for example, the period of the electronic device may be shorter than the period of the electronic device searching for a signal in a normal operating mode, that is, an SAR scene, so that the frequency of the electronic device searching for a radiation signal is increased, and the possibility of searching for a signal can be increased; if the current remaining power of the electronic device is less than or equal to the preset remaining power threshold, the search period of the electronic device may be appropriately extended, for example, the current remaining power of the electronic device is made to be greater than the period of a search signal of the electronic device in a normal operating mode, i.e., an SAR scene, so as to ensure that the current remaining power of the electronic device can ensure that the electronic device can keep communicating for a longer time, reduce power consumption of the electronic device, improve the possibility of performing a distress operation by the electronic device, and ensure that a user can obtain a possibility of rescue.
Based on the foregoing embodiment, in other embodiments of the present application, after the electronic device performs step 204, the electronic device may further be configured to perform the following steps: starting an image acquisition unit, such as a camera, of the electronic device; acquiring a symbolic object in the current environment of the electronic equipment through an image acquisition unit to obtain an environment image; and if the signal intensity of the radiation signal searched by the communication unit is greater than or equal to the preset intensity, automatically sending the environment image to the target communication equipment. Therefore, the rescue personnel can quickly locate the position of the user through the environment image so as to quickly reach the position of the user, rescue the user is implemented, and rescue efficiency is improved.
Based on the foregoing embodiment, in other embodiments of the present application, the present application further provides a signal control method, before the electronic device executes step 201, the method may further be used for the following steps: if the electronic equipment is detected to be in a position information reporting mode currently, acquiring reference position information of the electronic equipment at intervals of a preset time interval; reporting the reference position information to a server; correspondingly, the specific implementation process of step 204 may be: if the communication unit is successfully in communication connection with the base station, sending a trigger signal to a server; the triggering signal is used for indicating the server to perform distress processing based on the reference position information corresponding to the electronic equipment and the stored user information corresponding to the electronic equipment, and the distress operation comprises an operation of sending the triggering signal to the server. That is to say, before the electronic device enters the distress mode, when the electronic device is in the reporting position information mode, the electronic device collects the reference position information of the electronic device at each preset time interval and reports the collected reference position information to the server, when the electronic device searches for the radiation signal of the base station with the target radio frequency power, only one trigger signal needs to be sent to the server, and the server can perform subsequent alarm operation, so that the energy consumption of the electronic device is effectively saved, and the alarm efficiency is improved.
Based on the foregoing embodiment, in other embodiments of the present application, the current location of the electronic device may be location information of a base station closest to the electronic device, which is acquired by the electronic device, or may also be GPS location information of the electronic device.
Based on the foregoing embodiments, an embodiment of the present application provides a signal control method, including the following steps:
step a11, the user triggers the mobile terminal to make the mobile terminal in the outdoor sport mode.
Step a12, in the moving process of the user, if the mobile terminal detects that the received mobile communication network signal is weak, namely the mobile terminal is at the edge position of the network signal, automatically recording the current GPS positioning position, reminding the user that the mobile terminal is at the edge position of the signal coverage, and confirming whether to upload the current time, position and/or environment photo information to the server.
Step a13, the user triggers the mobile terminal to make the mobile terminal enter a distress mode.
Step a14, the mobile terminal can not search the mobile communication network signal currently, and prompts the user the distance between the signal coverage edge position recorded in step a12 and the current position, and the time required for reaching the signal coverage edge position recorded in step a12, so as to remind the user to return to the original position.
Step a15, the mobile terminal removes the radio frequency power limit of modem, i.e. SAR output power (TX power) limit, and enters into the distress mode, so that the mobile terminal searches for signal transmission with the maximum radio frequency power to successfully call out the distress call more quickly.
In the distress mode, the process of the mobile terminal searching for signal transmission with the maximum radio frequency transmission power and establishing communication connection with the base station may be as follows:
and b11, when recognizing that the user confirms that the mobile terminal enters the help-seeking mode, the electronic operation Processor (AP) of the mobile terminal informs the Modem.
Step b12, the Modem combines with the current weak signal environment, and transmits a search signal according to the radio frequency transmission power required by the network to establish connection with the mobile terminal, when the calling fails due to weak search signal, the mobile terminal can control the mobile terminal to gradually raise the radio frequency transmission power in a preset stepping mode, and the process is circulated until the calling and help-seeking telephone is successful, or when the Maximum Transmission Power Limit (MTPL) allowed by the mobile terminal device is not limited by SAR and the calling and help-seeking telephone is successful, the mobile terminal device establishes communication connection with the base station when the Maximum Transmission Power Limit (MTPL) allowed by the mobile terminal device is reached.
The maximum radio frequency transmitting power of the mobile terminal in the distress mode is higher than that of the mobile terminal without the limitation of the SAR power upper limit because the mobile terminal removes the limitation operation of the SAR power upper limit, and the corresponding maximum radio frequency transmitting power can reach the radio frequency calibration maximum power value of the mobile terminal when the mobile terminal removes the limitation of the SAR power upper limit.
For example, when the upper limit of the SAR power is not removed, when the Mobile terminal supports 3gpp NR/LTE/W Mobile network wireless communication of the third generation, the maximum radio frequency transmission power allowed when the Mobile terminal normally calls out/accesses a call is generally about 23 decibels (dB), and when the Mobile terminal supports Global System for Mobile Communications (Global System for Mobile Communications), the maximum radio frequency transmission power allowed when the Mobile terminal normally calls out/accesses a call is generally about 32 dB. Correspondingly, after SAR power limitation is removed, when the mobile terminal device supports 3gpp NR/LTE/W, the maximum radio frequency calibration power value which can be reached by the maximum radio frequency transmitting power allowed during normal calling/accessing of the mobile terminal device is about 25dB, and when the mobile terminal device supports GSM, the maximum radio frequency transmitting power allowed during normal calling/accessing of the mobile terminal device is about 33.5, so that under a weak signal field, the radio frequency transmitting power is almost improved by 1.5 to 2dB, the quality of a radiation signal of the mobile terminal device is obviously improved, the error rate and/or the signal demodulation failure rate of the weak signal when the mobile terminal device is communicated with a base station are reduced, and the calling/accessing success rate is improved.
Step a16, after the mobile terminal calls out the emergency call and/or reports the distress information, the user can actively control the mobile terminal to exit the distress mode and recover to the outdoor sport mode or the normal applicable mode.
Wherein, the user can control the mobile terminal to exit the help seeking mode only after obtaining the help.
