When the terminal device is within the signal coverage of the network device, the terminal device may establish a connection with the network device based on the cellular network communication unit to contact the outside world. Such as terminal device 103 and terminal device 104 are in a signal coverage 1021 of network device 102, based on cellular network communication unit 1032 and cellular network communication unit 1042, terminal device 103 may establish a connection with terminal device 104 through network device 102 and transmit data, such as terminal device 103 may make a call or send a message to terminal device 104.

When the terminal device is out of the signal coverage range of the network device, the terminal device can transmit information with other terminal devices based on the C-V2X communication unit. Such as terminal device 103 being within signal coverage 1021 of network device 102, based on C-V2X communication unit 1031, terminal device 103 may send a message based on a C-V2X sidelink communication protocol. Based on the C-V2X communication unit 1041, the terminal device 104 may receive the message based on a C-V2X sidelink communication protocol.

For example, the terminal device 103 in fig. 1 is a device for asking for help, and may be referred to as a help asking device. After the help-seeking device starts the help-seeking function, the information may be broadcast based on C-V2X, and the information has a certain receivable area, and when the terminal device 104 or the terminal device 105 (the terminal device 104 and the terminal device 105 are devices of search and rescue workers, and may be referred to as search and rescue devices) moves to the area, the information broadcast by the terminal device 103 may be received based on C-V2X. So that the user of the terminal device 103 can be rescued more quickly.

It can be seen that the person is trapped or needs to be rescued, which may often be outside the signal coverage of the network equipment, and cannot communicate with the outside world through the cellular network. In the embodiment of the application, the terminal device is provided with the C-V2X communication unit, so that the terminal device can send messages based on a C-V2X sidelink communication protocol under the condition that the terminal device is out of the signal coverage range of the network device, and the rescue possibility can be improved.

On the other hand, because the personnel search and rescue can be carried out based on the C-V2X signal in the embodiment of the application, compared with a scheme of searching for the trapped user based on a Radio Frequency Identification (RFID) technology, the coverage range of the C-V2X signal is larger, and a foundation is laid for searching for the trapped user more timely. In addition, the C-V2X communication unit can be integrated on the handheld terminal device, so that a user can carry the communication unit with the handheld terminal device, and compared with the help-seeking device needing to carry a specific beacon, the scheme provided by the embodiment of the application can greatly reduce the threshold of help-seeking and increase the help-seeking probability. Moreover, compared with rescue technologies such as thermal imaging, the signal emitted based on C-V2X in the embodiment of the application is less prone to environmental interference.

In fig. 3a, ANT _1 denotes a first antenna, ANT _ N denotes an nth antenna, and N is a positive integer greater than 1. Tx denotes a transmit path, rx denotes a receive path, and different numbers denote different paths. Each path may represent a signal processing channel. Where FBRx denotes a feedback reception path, PRx denotes a main reception path, and DRx denotes a diversity reception path. HB denotes high frequency, LB denotes low frequency, and both denote relative high and low frequencies. BB denotes a baseband. It should be understood that the labels and components in fig. 3a are for illustrative purposes only, as only one possible implementation, and that other implementations are also encompassed by the present embodiments. For example, a communication device may include more or fewer paths, including more or fewer components.

The application subsystem can be used as a main control system or a main computing system of the communication device, is used for running a main operating system and an application program, manages software and hardware resources of the whole communication device, and can provide a user operation interface for a user. In addition, driver software associated with other subsystems (e.g., baseband subsystem) may also be included in the application subsystem.

The application subsystem may include one or more processors. The plurality of processors may be a plurality of processors of the same type or may comprise a combination of processors of multiple types. In this application, the processor may be a general-purpose processor or a processor designed for a specific field. For example, the processor may be a Central Processing Unit (CPU), a Digital Signal Processor (DSP), or a Micro Control Unit (MCU). The processor may also be a Graphics Processing Unit (GPU), an image signal processing unit (ISP), an Audio Signal Processor (ASP), and an AI processor specifically designed for Artificial Intelligence (AI) applications. AI processors include, but are not limited to, neural Network Processing Units (NPUs), tensor Processing Units (TPUs), and processors known as AI engines.

In fig. 3a, a radio frequency integrated circuit (including RFIC1, and one or more optional RFICs 2) and a radio frequency front end device may together comprise a radio frequency subsystem. The RF subsystem may be divided into a RF receive path (RF receive path) and a RF transmit path (RF transmit path) according to the receiving or transmitting path of the signal. The rf receive channel may receive an rf signal via an antenna, process (e.g., amplify, filter, and downconvert) the rf signal to obtain a baseband signal, and deliver the baseband signal to the baseband subsystem. The rf transmit channel may receive the baseband signal from the baseband subsystem, process (e.g., upconvert, amplify, and filter) the baseband signal to obtain an rf signal, and finally radiate the rf signal into space via an antenna. The radio frequency integrated circuit may be referred to as a radio frequency processing chip or a radio frequency chip.

In particular, the rf subsystem may include antenna switches, antenna tuners, low Noise Amplifiers (LNAs), power Amplifiers (PAs), mixers (mixers), local Oscillators (LOs), filters (filters), and other electronic devices, which may be integrated into one or more chips as desired.

The baseband signal processing operations are also not exactly the same for different radio access technologies, such as 5G NR and 4G LTE.

In addition, since the rf signal is usually an analog signal, the signal processed by the baseband subsystem is mainly a digital signal, and an analog-to-digital conversion device is also required in the communication device. In the embodiment of the present application, the analog-to-digital conversion device may be disposed in the baseband subsystem, and may also be disposed in the radio frequency subsystem. The analog-to-digital conversion device includes an analog-to-digital converter (ADC) that converts an analog signal into a digital signal, and a digital-to-analog converter (DAC) that converts a digital signal into an analog signal.

The hardware accelerator can be used for specially finishing sub-functions with large processing overhead, such as assembly and analysis of data packets (data packets), encryption and decryption of the data packets, and the like. These sub-functions may also be implemented using general-purpose processors, but for performance or cost considerations, it may be more appropriate to use hardware accelerators. In a specific implementation, the hardware accelerator is mainly implemented by an Application Specific Integrated Circuit (ASIC). Of course, one or more relatively simple processors, such as MCUs, may also be included in the hardware accelerator.

In the embodiment of the application, the baseband subsystem and the radio frequency subsystem jointly form a communication subsystem, and provide a wireless communication function for the communication device. In general, the baseband subsystem is responsible for managing the software and hardware resources of the communication subsystem and may configure the operating parameters of the radio frequency subsystem. The processor of the baseband subsystem may run therein a sub-operating system of the communication subsystem, which is often an embedded operating system or a real time operating system (real time operating system), such as a VxWorks operating system or a QuRT system of the kowtthrough company.

The baseband subsystem may be integrated into one or more chips, which may be referred to as baseband processing chips or baseband chips. The baseband subsystem may be implemented as a stand-alone chip, which may be referred to as a modem (modem) or modem chip. The baseband subsystem may be manufactured and sold in units of modem chips. modem chips are also sometimes referred to as baseband processors or mobile processors. In addition, the baseband subsystem may be further integrated into a larger chip, and manufactured and sold in units of larger chips. This larger chip may be referred to as a system-on-chip, system-on-a-chip or system-on-a-chip (SoC), or simply as an SoC chip. The software components of the baseband subsystem may be built in the hardware components of the chip before the chip leaves factory, or may be imported into the hardware components of the chip from other nonvolatile memories after the chip leaves factory, or may be downloaded and updated in an online manner through a network.

In addition, the communication device also includes a memory, such as the memory and mass storage of fig. 3 a. In addition, one or more buffers may be included in the application subsystem and the baseband subsystem, respectively. In a specific implementation, the memory can be divided into a volatile memory (NVM) and a non-volatile memory (NVM). The volatile memory is a memory in which data stored therein is lost when power supply is interrupted. Currently, volatile memory is mainly Random Access Memory (RAM), including Static RAM (SRAM) and Dynamic RAM (DRAM). A nonvolatile memory is a memory in which data stored inside is not lost even if power supply is interrupted. Common non-volatile memories include Read Only Memories (ROMs), optical disks, magnetic disks, and various memories based on flash memory technology. Generally, the memory and cache may be volatile memory, and the mass storage may be non-volatile memory, such as flash memory.

In situations where the wireless communication device may be battery powered and the time to be saved is uncertain because of the trapped personnel, it is particularly important to try to save power in order to strive for more time for the user. And the first module is disabled through S703, so that the electric quantity can be saved as much as possible.

S704, an emergency call is attempted via the second radio frequency channel, is the call successful? The second radio frequency channel is used for transmitting signals in a corresponding frequency band of the cellular network.

If the call is successful, executing S705;

if the call fails, S706 and S707 are performed.

In S704, the emergency call may be made through the cellular network module, in which case, if the cellular network module is disabled, the disabling may be canceled first, and then the emergency call may be made through the cellular network module.

S705, playing the pre-stored SOS record.

When the call is successful in S704, the user may directly communicate with the called party, but in some cases, the user may not be able to speak, such as injured, weak, and the like, in this case, if the caller does not make a sound within a preset time period, it is determined that the user cannot communicate with the person in speech due to being trapped, and then a distress recording may be played through S705. In a possible embodiment, the recording of the help may be preset by the user or updated, for example, when the user arrives at a new exploration place, the current time, the starting location, the direction to advance, the planned destination, and the like may be entered into the recording of the help, so that the user can be searched and rescued more quickly at a later time.

S706, the cellular network of the wireless communication device is disabled.

Through S706, since the cellular network module is disabled, the wireless communication device does not search for nearby network signals, and thus power of the wireless communication device can be saved.

And S707, sending the first message through the first radio frequency channel. The first radio frequency channel is used for transmitting signals in a frequency band corresponding to C-V2X.

In the embodiment of the application, the first message needs to be sent through the C-V2X module, and if the C-V2X module is disabled, in S707, the disabling of the C-V2X needs to be cancelled first, and then the first message needs to be sent.

In this embodiment, the first message may be a first help-seeking message. Since the signal coverage of the first message is relatively fixed, when the first message is received by a rescuer carrying the search and rescue equipment, the approximate position of the help seeking equipment can be determined even if the first message does not contain the position information of the wireless communication device. And then the search and rescue range can be reduced.

In this embodiment, the first message may be a preset message. At least one of the following contents b1 to b4 may be included in the first message:

and the content b1 is used for indicating that the first message is indicating information of the first help-seeking message. The first message can be identified as the help seeking message by the search and rescue equipment according to the indication information for the Application ID of the field rescue APP.

Content b2, the current location information of the wireless communication device, is referred to as first location information in the embodiment of the present application for the sake of distinction. The position information may include longitude, latitude, altitude, etc. of the location of the distress device.

Content b3, user identification information of the person seeking help. Such as the user's name, identification number, etc.;

content b4, generation time of the first message.

In S707, in order to further reduce power consumption, the number of times of transmission of the first message is at least one of: presetting a value; or positively correlated with the power of the wireless communication device. For example, if the power of the wireless communication device is high, the number of times of sending the first message may be large, so that the chance of rescue may be increased. Otherwise, the electricity quantity of the wireless communication device is lower, so that the sending times of the first message can be reduced, the standby time of the wireless communication device is prolonged, and the rescue opportunity is increased.

In S707, to further reduce power consumption, the wireless communication device may transmit a first message over a first radio frequency channel based on a Pedestrian-to-evolution (P2X) mode associated with the C-V2X sidelink communication.

In this embodiment of the present application, in the case of sending the first message based on the P2X mode related to the C-V2X sidelink communication, it may be:

selecting a resource for transmitting the first message from a pre-configured resource pool based on a random selection (random selection) mode or a partial Sensing (partial Sensing) mode.

For english, the following can be referred to: transmission of P2X related C-V2X sidelink communication, A UE configured to transmit P2X related C-V2X sidelink communication shall:

If both partialSensing and randomSelection is included in resourceSelectionConfigP2X of the pool selected,the selection between partial sensing and random selection is left to UE implementation。

in one possible embodiment, a first radio frequency receive channel of a first radio frequency channel of a wireless communication device is powered down when a resource for transmitting a first message is selected from a pre-configured resource pool based on a random selection (random selection) mode.

In one possible embodiment, a first rf receive channel of a first rf channel of a wireless communication device is intermittently powered down when a resource for transmitting a first message is selected from a pre-configured resource pool based on a partial Sensing (partial Sensing) mode. The intermittent power-down state indicates that the first rf receiving channel is switched between power-up and power-down, where the power-up duration and the power-down duration may be equal to or unequal to each other, such as 900 milliseconds (ms) for power-down and 100ms for power-up. Or, the two times of power-on are not equal, for example, when the wireless communication device has low power, the power-on duration may be shorter, and conversely, the power-on duration may be longer.

In one possible embodiment, in the case where the resource for transmitting the first message is selected from a pre-configured pool of resources based on a partial Sensing (partial Sensing) mode: and receiving a signal with a third time length through a first radio frequency receiving channel in the first radio frequency channel, and selecting a resource for transmitting the first message from a pre-configured resource pool according to the signal received in the third time length. The third time length is less than a fourth time length, and the fourth time length is the time length of receiving signals when the resource used for transmitting the first message is selected from the pre-configured resource pool in a Sensing mode.

S708, after the first message with preset times is sent through the first radio frequency channel, the mobile terminal enters a dormant state, and the dormant duration is set.

It should be noted that the first message may be sent multiple times, and may be sent at a certain time interval, for example, the first message may be sent at an interval of 1 minute until the preset number of times of sending the first message is completed, and the sleep state may be entered through S708. The sleep duration may be set by a sleep wakeup timer.

In S708, the sleep duration is at least one of: presetting a value; or inversely related to the power of the wireless communication device. The wireless communication device has a short sleep time when the power is high, so as to increase the chance of rescue. The sleep time is longer when the electric quantity of the equipment is low, so that the power consumption is saved, the help-seeking time is prolonged, and the help-seeking chance is increased.

In the embodiment of the application, after the wireless communication device enters the sleep state, the corresponding C-V2X module and the corresponding positioning module are in the power-off state, so that the power consumption is saved.

S709, determine whether the sleep duration has arrived?

If not, repeating the step S709;

if yes, executing S710;

s710, second location information of the wireless communication device is acquired.

In S710, since the current location information of the wireless communication device needs to be acquired by the positioning module, if the positioning module is powered off, the positioning module needs to be powered on first, or the disabling of the positioning module is cancelled. In the embodiment of the present application, the wireless communication apparatus in S710 acquires the current location information, and in order to distinguish from the first location information in the foregoing, the current location information is referred to as second location information.

S711, determine whether a distance between two locations indicated by the first location information and the second location information is greater than a preset distance threshold?

If so, go to S704;

if not, S707 is executed.

As can be seen from S711, only in the case that the distance between the two locations indicated by the first location information and the second location information is greater than the preset distance threshold, the mobile terminal may move to the network signal coverage area, so that the disabling of the cellular network of the wireless communication device is cancelled, and the emergency call is attempted based on the cellular network, and the step of adding the emergency call in the distress flow may improve the success rate of distress call. And when the distance between the two positions is not greater than the preset distance threshold, the cellular network is not disabled, so that the power consumption can be further reduced.

As can be seen from the scheme in fig. 7, in the embodiment of the present application, if the distress mode is turned on, an emergency call may be made or a message may be periodically sent through C-V2X, so as to increase the probability of being rescued, and in the process, unnecessary modules are disabled as much as possible, so as to further reduce power.

It should be noted that in the embodiment of the present application, it is not necessary to make an emergency call based on a cellular network after the help-seeking function of the wireless communication device is turned on, for example, some wireless communication devices do not have a cellular network module, in which case, the foregoing S704 to S706 and S711 may be removed accordingly. And S707 is executed after S710.

In this embodiment of the application, after the help-seeking module is turned on, if it is detected that the user exits from the help-seeking mode, in a possible implementation manner, the state of the first module may be restored to before the help-seeking function is turned on according to the first disabled state information of the first module in the foregoing S702. And restoring the state of the second module to the state before the help-seeking function is started according to the second disabled state information of the second module in the step S702. For example, when the first disable state information indicates that the first module is not disabled before the first module starts the distress function, after exiting the distress mode, if the first module is in the disable state, the disabling of the first module is cancelled.

Based on the above, fig. 8 schematically illustrates a flow chart of a rescue method suitable for a wireless communication device according to an embodiment of the present application, where the method may be performed by the terminal device or a component or chip disposed inside the terminal device.

As shown in fig. 8, the method includes:

and S801, starting a search and rescue function.

S802, after the help-seeking function is started, third forbidden state information of the third module is recorded, and the third forbidden state information is used for indicating whether the third module is forbidden before the search and rescue function is started. The third module includes at least one of a positioning module or C-V2X.

And S803, receiving signals in the frequency band corresponding to the C-V2X through the first radio frequency channel based on the opening of the C-V2X module. And after determining the received distress message (which may be referred to herein as a second distress message for purposes of distinction), displaying the location information of the rescuer on the wireless communication device.

In a possible embodiment, after receiving the signal in the frequency band corresponding to C-V2X through the first radio frequency channel in S803, the signal may be analyzed, and if the instruction information for indicating that the signal includes the distress message is analyzed, it is determined that the signal includes the distress message, and further, the location information of the rescuer is determined according to the message. In a possible implementation manner, the location information carried in the received message may be determined, and in another possible implementation manner, the location information is not carried in the received message, and then an approximate area range where the help seeker is located may be determined according to the signal strength of the received message, so that the search and rescue speed may be increased.

In yet another possible embodiment, indication information indicating that the distress message is included in the signal may be placed in a header of the message (such as a header of the second distress message), and thus, when the indication information is parsed, the parsing of subsequent content may be resumed. If the indication information is not analyzed, the subsequent content is not analyzed, and the message can be discarded, so that the data volume of the search and rescue equipment for processing the message can be reduced.

Before S803, synchronization may be performed based on the turned-on positioning module. If the positioning module is not started, the positioning module needs to be started, and then synchronization is carried out based on the started positioning module.

In this embodiment of the application, if the user is detected to exit the search and rescue mode after the search and rescue module is started, in a possible implementation manner, the state of the third module may be restored to before the search and rescue function is started according to the third disabled state information of the third module in the foregoing S802. For example, in a case where the third disabled state information indicates that the third module is disabled before the search and rescue function is turned on, after exiting the search and rescue mode, if the third module is in an un-disabled state, disabling of the third module is disabled. For another example, in a case that the third disabled state information indicates that the third module is not disabled before the search and rescue function is started, after the search and rescue mode is exited, if the third module is in a disabled state, the disabling of the third module is cancelled.
