Description

Communication method, broadband terminal and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communications method, a broadband narrowband terminal, and a storage medium.

Background

Broadband and narrowband terminals generally support communication over both broadband and narrowband, with such broadband and narrowband terminals typically being predominantly used for broadband and narrowband emergency use in a few cases.

The standby current of the narrow-band communication module in the wide-band and narrow-band terminal is larger, the power consumption is relatively higher, and if the wide-band communication module and the narrow-band communication module are normally started at the same time, the standby power consumption of the wide-band and narrow-band terminal is greatly increased, and the standby time is obviously shortened. If the wideband communication module is selected to be always on, and the narrowband communication module is selected to be always off or to be deeply asleep, communication through the narrowband communication module cannot be performed in time when no wideband signal or weak wideband signal occurs.

In summary, how to make the narrowband communication module respond to the communication requirement in time under the conditions of reducing the power consumption and prolonging the standby time for the broadband terminal has become a problem to be solved in the present day.

Detailed Description

In order to make the present application solution better understood by those skilled in the art, the following description will clearly and completely describe the technical solution in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The terms "first," "second," "third," "fourth" and the like in the description and in the claims of this application and in the above-described figures, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

In the related art, for a wide-narrow band terminal, if the wide-band communication module and the narrow-band communication module are both selected to be normally opened, the standby power consumption of the wide-narrow band terminal is greatly increased due to the larger standby current of the narrow-band communication module, and the standby time is obviously shortened. If the normally-on broadband communication module is selected and the normally-off narrowband communication module is selected, when the situation that the broadband network signal is not available or weak occurs, the narrowband communication module is in a normally-off state, so that the problem that the narrowband communication module cannot be used for communication in time occurs. If the narrowband communication module is selected to be in a deep sleep state, the narrowband communication module in the deep sleep state does not receive the narrowband communication information in a longer sleep period, and only receives the narrowband communication information in a short wake-up period, so that the problem that the narrowband communication module cannot be used for communication in time still exists.

In order to solve the problems of the related art, the embodiments of the present application provide a communication method, which can reduce standby power consumption of a broadband and narrowband terminal, prolong standby time, and enable a narrowband communication module to respond to communication requirements in time.

Specifically, in the communication method provided in the embodiment of the present application, the first wideband/narrowband terminal may detect the quality of the own wideband network signal. When the first broadband narrowband terminal determines that the quality of the broadband network signal meets the first preset condition (the first preset condition is that the broadband network signal is poor or unstable), the first broadband narrowband terminal can control the narrowband communication module to enter a working mode and send target broadcast information through the broadband communication module, wherein the target broadcast information comprises a target control instruction for informing other broadband narrowband terminals to control the narrowband communication module to enter the working mode; by sending the target broadcast information, other broadband and narrowband terminals can control the narrowband communication module to enter the working mode.

According to the communication method provided by the embodiment of the application, on one hand, whether the narrowband communication module enters the working mode is automatically controlled by monitoring the quality of the broadband network signal of the broadband terminal; on the other hand, after a certain broadband and narrowband terminal controls the narrowband communication module to enter the working mode, the target broadcast information is sent through the broadband communication module, so that other broadband and narrowband terminals control the narrowband communication module to enter the working mode, and the broadband and narrowband terminal can normally communicate with other broadband and narrowband terminals through narrowband network signals. Therefore, only under the condition that the broadband network signal is weakened or unstable, the narrowband communication module is controlled to enter the working mode, the power consumption required by the broadband and narrowband terminal can be reduced, the standby time of the broadband and narrowband terminal is prolonged, and the narrowband communication module can timely respond to the communication requirement.

It should be understood that the communication method provided in the embodiments of the present application may be applied to any wideband and narrowband terminal, that is, may be applied to any terminal device that supports communication through a wideband network signal and a narrowband network signal, where the terminal device may be, for example, a smart phone, a tablet computer, a personal digital assistant (Personal Digital Assistant, PDA), and the like, and the wideband and narrowband terminal is not specifically limited herein. Furthermore, the wideband in the embodiments of the present application may be, for example, a long term evolution (Long Term Evolution, LTE) cluster, a third Generation mobile communication technology (3 rd-Generation, 3G), a fourth Generation mobile communication technology (the 4th Generation mobile communication technology,4G), a fifth Generation mobile communication technology (5th Generation Mobile Communication Technology,5G), and the like, and the narrowband may be, for example, a narrowband professional digital cluster PDT, a digital mobile radio standard (Digital Mobile Radio, DMR), and the like, and the wideband and the narrowband in the embodiments of the present application are not limited in any way.

The communication method provided by the application is described in detail below through a method embodiment.

Referring to fig. 1, fig. 1 is a schematic flow chart of a communication method according to an embodiment of the present application; the implementation body of the communication method may be specifically a first wideband/narrowband terminal, and the first wideband/narrowband terminal may be any wideband/narrowband terminal. As shown in fig. 1, the communication method includes the steps of:

Step 101: and detecting the quality of the broadband network signal of the first broadband and narrowband terminal.

In practical application, the first wideband terminal may detect the quality of its own wideband network signal in real time or periodically, and determine whether the detected quality of the wideband network signal meets a first preset condition. The first preset condition is a measurement condition that the broadband network signal is weakened or unstable; if the broadband network signal meets the first preset condition, indicating that the broadband network signal is poor or unstable; if the broadband network signal does not meet the first preset condition, the broadband network signal is stronger and more stable.

Illustratively, when the first wideband and narrowband terminal communicates with the base station, the radio frequency signal strength may be detected, which may reflect the quality of the wideband network signal of the first wideband and narrowband terminal accordingly. If the detected radio frequency signal strength is lower than the preset strength threshold, the fact that the broadband network signal of the first broadband and narrowband terminal is weaker is indicated, and at the moment, the quality of the broadband network signal of the first broadband and narrowband terminal can be considered to meet a first preset condition. If the detected fluctuation amplitude of the radio frequency signal intensity exceeds the preset amplitude threshold, the fact that the broadband network signal of the first broadband and narrowband terminal is unstable is indicated, and at the moment, the quality of the broadband network signal of the first broadband and narrowband terminal can be considered to meet the first preset condition.

Of course, in practical applications, the first wideband/narrowband terminal may also detect whether the quality of the wideband network signal meets the first preset condition in other manners, which is not limited in this application.

Step 102: when the quality of the broadband network signal meets a first preset condition, controlling a narrowband communication module of the first broadband terminal to enter a working mode, and transmitting target broadcast information through the broadband communication module of the first broadband terminal; the first preset condition is that the broadband network signal is poor or unstable; the target broadcast information comprises a target control instruction, and the target control instruction is used for informing other broadband and narrowband terminals to control the narrowband communication module to enter the working mode.

If the first wide-narrow-band terminal determines that the quality of the broadband network signal meets a first preset condition, that is, the first wide-narrow-band terminal determines that the broadband network signal is poor or unstable, the first wide-narrow-band terminal can control the narrow-band communication module to enter a working mode, that is, the narrow-band communication module of the first wide-narrow-band terminal works normally, and can receive or send information through the narrow-band network signal normally. Meanwhile, the first broadband and narrowband terminal can also send target broadcast information to other terminals through the broadband communication module of the first broadband and narrowband terminal, wherein the target broadcast information at least comprises a target control instruction, and the target control instruction is used for informing the other broadband and narrowband terminals to control the narrowband communication module of the first broadband and narrowband terminal to enter a working mode. In one possible implementation, the narrowband communication module of the first wideband narrowband terminal may be in a closed mode by default; in this case, when the first wideband terminal detects that the own wideband network signal meets the first preset condition, the narrowband communication module can be controlled to switch from the off mode to the on mode. The narrowband communication module is not usable in the off mode, i.e. does not support communication via narrowband network signals; the narrowband communication module can be normally used in an on mode, namely, the narrowband communication module supports the sending and receiving of information through narrowband network signals.

In another possible implementation manner, the narrowband communication module of the first wideband narrowband terminal may be in a sleep mode by default, in which case, when the first wideband narrowband terminal detects that the wideband network signal of the first wideband narrowband terminal meets a first preset condition, the narrowband communication module of the first wideband narrowband terminal may be controlled to switch from the sleep mode to the wake-up mode. The narrowband communication module can be periodically awakened in the sleep mode, namely, when the narrowband communication module works in the sleep mode, the working period of the narrowband communication module comprises a sleep period and an awakening period; in the sleep cycle, the narrowband communication module is in a sleep state, which stops receiving information transmitted by narrowband network signals; in the wake-up period, the narrowband communication module is in a wake-up state, and can receive information which is missed in the sleep period and transmitted through the narrowband network signal, and information which is transmitted through the narrowband network signal by other terminals in the wake-up period. The narrowband communication module is continuously in an awake state in an awake mode, that is, when the narrowband communication module works in the awake mode, the narrowband communication module can instantly receive information transmitted by other terminals through narrowband network signals, and the narrowband communication module can also transmit information through narrowband network signals.

Optionally, in practical application, the narrowband communication module may be automatically controlled by the wideband communication module in the first wideband narrowband terminal to enter the working mode. For example, the hardware circuit structure corresponding to the wideband communication module may include a pin for controlling the narrowband communication module to be turned on, and when it is determined that the narrowband communication module needs to be put into the working mode, the hardware circuit structure corresponding to the wideband communication module may control the hardware circuit structure corresponding to the narrowband communication module to start to operate through the pin, so that the narrowband communication module is put into the working mode.

In one possible implementation manner, if the narrowband communication module of the first wideband narrowband terminal communicates in the narrowband trunking mode, the target broadcast information sent by the first wideband narrowband terminal through the wideband communication module thereof may only include the target control instruction. Correspondingly, other wideband and narrowband terminals receiving the target broadcast information can start the narrowband communication module of the other wideband and narrowband terminals so as to communicate with the first wideband and narrowband terminal in a narrowband trunking mode.

In another possible implementation manner, if the narrowband communication module of the first wideband-narrowband terminal communicates in the narrowband through mode (Direct Mode Operation, DMO), the target broadcast information sent by the first wideband-narrowband terminal through the wideband communication module thereof may include, in addition to the target control instruction, positioning information of the first wideband-narrowband terminal itself, where the positioning information is used to indicate that the wideband-narrowband terminal that receives the target broadcast information detects whether the wideband-narrowband terminal itself is located in a communication range of the narrowband through mode corresponding to the first wideband-narrowband terminal, and responds to the target control instruction in the target broadcast information if it is determined that the wideband-narrowband communication module is located in the communication range of the narrowband through mode corresponding to the first wideband-narrowband terminal.

That is, when the narrowband communication module of the first wideband narrowband terminal communicates under the narrowband DMO, the target broadcast information transmitted by the first wideband narrowband terminal through the wideband communication module thereof may include current positioning information and a target control instruction of the first wideband narrowband terminal itself; correspondingly, the broadband terminal receiving the target broadcast information can judge whether the broadband terminal is positioned in the communication range of the narrow-band through mode corresponding to the first broadband terminal according to the positioning information of the broadband terminal and the positioning information carried in the target broadcast information, if so, the narrowband communication module is controlled to enter the working mode in response to the target control instruction carried in the target broadcast information, and if not, the narrowband communication module is not required to respond to the target control instruction carried in the target broadcast information.

The first broadband and narrowband terminal controls the narrowband communication module to enter a working mode, and after target broadcast information is sent out through the broadband communication module, the quality of a broadband network signal of the first broadband and narrowband terminal can be continuously detected, and whether the quality of the broadband network signal meets a second preset condition is judged; the second preset condition is that the broadband network signal is normal, and if the second preset condition is met, the broadband network signal is recovered to be normal, and if the second preset condition is not met, the broadband network signal is not recovered to be normal.

The first wideband terminal may detect whether the wideband network signal of the first wideband terminal is normal or not based on the radio frequency signal strength when the first wideband terminal communicates with the base station; if the radio frequency signal strength exceeds the preset strength threshold value and the fluctuation amplitude of the radio frequency signal strength does not exceed the preset amplitude threshold value, the broadband network signal of the first broadband and narrowband terminal can be considered to be recovered to be normal, and the second preset condition is met; otherwise, if the radio frequency signal strength does not exceed the preset strength threshold, or the fluctuation amplitude of the radio frequency signal strength exceeds the preset amplitude threshold, the broadband network signal of the first broadband and narrowband terminal can be considered to be not recovered to be normal, and the second preset condition is not satisfied.

Of course, in practical applications, the first wideband/narrowband terminal may also detect whether the quality of the wideband network signal meets the second preset condition in other manners, which is not limited in this application.

When the first broadband and narrowband terminal determines that the quality of the broadband network signal of the first broadband and narrowband terminal does not meet the second preset condition, namely, the first broadband and narrowband terminal determines that the broadband network signal of the first broadband and narrowband terminal does not return to normal, the first broadband and narrowband terminal keeps the narrowband communication module of the first broadband and narrowband terminal in a working mode, and sends reference broadcast information through the target communication module of the first broadband and narrowband terminal so that the narrowband communication modules of other broadband and narrowband terminals are in the working mode.

In one possible implementation, the first wideband narrowband terminal may send the first reference broadcast information through its narrowband communication module, so that the second wideband narrowband terminal controls its narrowband communication module to maintain an operational mode, where the second wideband terminal is a wideband narrowband terminal that has controlled its narrowband communication module to enter an operational mode in response to the target broadcast information previously sent by the first wideband narrowband terminal.

Specifically, under the condition that the first broadband and narrowband terminal determines that the broadband network signal of the first broadband and narrowband terminal is not recovered to be normal, the first broadband and narrowband network can periodically send first reference broadcast information through the narrowband communication module of the first broadband and narrowband terminal, wherein the first reference broadcast information comprises a reference control instruction, and the reference control instruction is used for informing the broadband and narrowband terminal which has responded to the target broadcast information to keep the narrowband communication module of the first broadband and narrowband terminal in an operating mode. For example, it is assumed that the second wideband/narrowband terminal has previously received, through its wideband communication module, the target broadcast information sent by the first wideband/narrowband terminal, and responded to the target broadcast information, to control its narrowband communication module to enter the working mode, where, if the second wideband/narrowband terminal has received, through its narrowband communication module, the first reference broadcast information sent by the first wideband/narrowband terminal, the second wideband/narrowband terminal will keep its narrowband communication module in the working mode. Therefore, before the broadband network signal of the first broadband and narrowband terminal is recovered to be normal, the first broadband and narrowband terminal and the second broadband and narrowband terminal can normally communicate through the narrowband network signal.

In another possible implementation manner, the first wideband narrowband terminal may send the second reference broadcast information through the wideband communication module thereof, so that the third wideband narrowband terminal controls the narrowband communication module thereof to enter the working mode, where the third wideband narrowband terminal is a wideband narrowband terminal that does not control the narrowband communication module thereof to enter the working mode in response to the target broadcast information sent by the first wideband narrowband terminal.

In some cases, there may be a third wide-narrowband terminal, which may not have received the target broadcast information sent by the first wide-narrowband terminal before (narrowband communication module operating in narrowband trunked mode); or, such third narrowband terminal is not in the communication range of the narrowband through mode corresponding to the first wideband narrowband terminal before sending the target broadcast information at the first wideband narrowband terminal (the narrowband communication module works in the narrowband through mode), but as the first wideband narrowband terminal and/or the third wideband narrowband terminal move, the third wideband narrowband terminal moves to the communication range of the narrowband through mode corresponding to the first wideband narrowband terminal.

In order to enable the first wideband and narrowband terminal to normally communicate with the third wideband and narrowband terminal through narrowband network signals, the first wideband and narrowband terminal can also transmit second reference broadcast information through the wideband communication module thereof, and the second reference broadcast information is the same as the target broadcast information transmitted before. When the narrowband communication module of the first wideband narrowband terminal operates in the narrowband trunking mode, the second reference broadcast information may include a target control instruction, where the target control instruction is used to inform other wideband narrowband terminals to control the narrowband communication module thereof to enter the working mode. When the narrowband communication module of the first wideband and narrowband terminal works in the narrowband through mode, the second reference broadcast information can include current positioning information and target control instructions of the first wideband and narrowband terminal, the positioning information is used for indicating whether the wideband and narrowband terminal receiving the second reference broadcast information detects whether the wideband and narrowband terminal is located in a communication range of the narrowband through mode corresponding to the first wideband and narrowband terminal, and the target control instructions in the second reference broadcast information are responded under the condition that the narrowband communication module is located in the communication range of the narrowband through mode corresponding to the first wideband and narrowband terminal. .

Correspondingly, after the third broadband terminal receives the second reference broadcast information through the broadband communication module, the third broadband terminal can control the narrowband communication module to enter the working mode. In this way, the third wide-band terminal that has not received the target broadcast information before, or the third wide-band terminal that moves to the communication range of the narrow-band pass-through mode corresponding to the one wide-band terminal after the first wide-band terminal transmits the target broadcast information, may also be in communication with the first wide-band terminal through the narrow-band network signal.

It should be understood that, in practical application, the first wideband terminal may send only the first reference broadcast information, may send only the second reference broadcast information, and may send both the first reference broadcast information and the second reference broadcast information.

When the first wideband and narrowband terminal determines that the quality of the own wideband network signal meets a second preset condition, that is, when the first wideband and narrowband terminal determines that the own wideband network signal has recovered to be normal, the first wideband and narrowband terminal may stop sending the reference broadcast information. Specifically, the first broadband narrowband terminal may stop transmitting the first reference broadcast information through its narrowband communication module and stop transmitting the second reference broadcast information through its broadband communication module.

After the first broadband and narrowband terminal stops sending the reference broadcast information, the first broadband and narrowband terminal can also detect whether the first broadband and narrowband terminal receives target broadcast information or reference broadcast information sent by other broadband and narrowband terminals within a preset duration; if the first wideband and narrowband terminal does not receive the target broadcast information or the reference broadcast information sent by other wideband and narrowband terminals within the preset duration, the first wideband and narrowband terminal can control the narrowband communication module to exit the working mode.

Specifically, if the first wideband narrowband terminal determines that the own wideband network signal has recovered to be normal, and determines that the first wideband narrowband terminal does not need to communicate with other wideband narrowband terminals through narrowband network signals, the first wideband narrowband terminal may control the narrowband communication module to exit the working mode, for example, control the narrowband communication module to switch from the on mode back to the off mode, and also, for example, control the narrowband communication module to switch from the wake-up mode back to the sleep mode. Therefore, the narrowband communication module of the first broadband narrowband terminal is closed timely, and excessive power consumption of the first broadband narrowband terminal is avoided.

Optionally, after the first wideband/narrowband terminal controls the narrowband communication module to enter the working mode and sends the target broadcast information through the wideband communication module, and before detecting whether the quality of the own wideband network signal is recovered to be normal, the first wideband/narrowband terminal may also send at least one piece of reference broadcast information through the target communication module. Specifically, after the first wideband and narrowband terminal has sent the target broadcast information, it can detect whether the own wideband network signal is recovered to be normal after a period of time, in which, in order to ensure that the first wideband and narrowband terminal can normally communicate with other wideband and narrowband terminals, the first wideband and narrowband terminal can send the reference broadcast information through its target communication module; for example, the first wideband narrowband terminal may transmit the first reference broadcast information through its narrowband communication module and/or transmit the second reference broadcast information through its wideband communication module.

Referring to fig. 2, fig. 2 is a schematic flow chart of another communication method according to an embodiment of the present application; the implementation body of the communication method may specifically be a second wide-narrow-band terminal, and the second wide-narrow-band terminal may be any wide-narrow-band terminal. As shown in fig. 2, the communication method includes the steps of:

Step 201: when the second broadband terminal receives target broadcast information through a broadband communication module of the second broadband terminal, a target control instruction is acquired from the target broadcast information; the target control instruction is used for notifying the broadband and narrowband terminal which receives the target broadcast information to control the narrowband communication module to enter the working mode.

In practical application, after the second wideband/narrowband terminal receives the target broadcast information sent by the first wideband/narrowband terminal through the wideband communication module, a target control instruction can be extracted from the target broadcast information, where the target control instruction is an instruction issued by the first wideband/narrowband terminal and used for notifying the wideband/narrowband terminal that receives the target broadcast information to control the narrowband communication module to enter a working mode. The embodiment shown in fig. 1 has been described in detail, and details of the description of the target broadcast information can be found in the related description above, which is not repeated here.

In one possible implementation manner, if the narrowband communication module of the first wideband narrowband terminal communicates in the narrowband trunking mode, the target broadcast information sent by the first wideband narrowband terminal may only include the target control instruction. After receiving such target broadcast information, the second broadband narrow-band terminal can correspondingly and directly start the narrow-band communication module of the second broadband narrow-band terminal so as to communicate in a narrow-band trunking mode through the narrow-band communication module of the second broadband narrow-band terminal and the first broadband narrow-band terminal.

In another possible implementation manner, if the narrowband communication module of the first wideband-narrowband terminal communicates in the narrowband through mode, the target broadcast information sent by the first wideband-narrowband terminal may further include positioning information of the first wideband-narrowband terminal in addition to the target control instruction. In this case, after the second wideband/narrowband terminal receives the target broadcast information, the positioning information of the first wideband/narrowband terminal may also be obtained from the target broadcast information; then, determining whether the second broadband terminal is in a communication range of a narrow-band through mode corresponding to the first broadband terminal according to the positioning information of the second broadband terminal and the positioning information of the first broadband terminal; in case it is determined that the second wideband/narrowband terminal is within the communication range of the narrowband through mode corresponding to the first wideband/narrowband terminal, the subsequent step 202 is performed again.

Specifically, after the second wideband/narrowband terminal extracts the positioning information of the first wideband/narrowband terminal from the target broadcast information, the distance between the current positioning information of the second wideband/narrowband terminal and the positioning information of the first wideband/narrowband terminal can be calculated, and whether the second wideband/narrowband terminal is located in the communication range of the narrowband through mode corresponding to the first wideband/narrowband terminal is judged according to the distance. Typically, the communication range of the narrowband through mode may be 2 km to 3 km; of course, in practical application, the communication range of the narrowband through mode may also be set according to the actual communication condition.

Step 202: and responding to the target control instruction, and controlling the narrowband communication module of the second broadband narrowband terminal to enter a working mode.

When the narrowband communication modules of the first wideband narrowband terminal and the second wideband terminal communicate in the narrowband trunking mode, the second wideband terminal receives target broadcast information, extracts a target control instruction from the target broadcast information, and can directly respond to the target control instruction to correspondingly control the narrowband communication module to enter the working mode. For example, controlling the narrowband communication module itself to enter an on mode from an off mode; for another example, a narrowband communication module that controls itself enters an awake mode from a sleep mode, and so on.

When the narrowband communication modules of the first broadband narrowband terminal and the second broadband terminal communicate in the narrowband through mode, if the second broadband terminal determines that the second broadband terminal is positioned in the communication range of the narrowband through mode corresponding to the first broadband terminal according to the distance between the second broadband terminal and the first broadband terminal, the second broadband terminal can respond to a target control instruction in target broadcast information and correspondingly control the narrowband communication module to enter a working mode. For example, controlling the narrowband communication module itself to enter an on mode from an off mode; for another example, a narrowband communication module that controls itself enters an awake mode from a sleep mode, and so on.

Subsequently, if the second wideband and narrowband terminal receives the reference broadcast information sent by the first wideband and narrowband terminal through the narrowband communication module thereof, the second wideband and narrowband terminal can control the narrowband communication module thereof to keep the working mode; the reference broadcast information is transmitted by the first wideband/narrowband terminal after the target broadcast information is transmitted.

Specifically, after the first broadband terminal sends the target broadcast information through the broadband communication module, the first broadband terminal can periodically detect whether the broadband network signal of the first broadband terminal is recovered to be normal, if the broadband network signal of the first broadband terminal is determined not to be normal, the first reference broadcast information is sent through the narrowband communication module of the first broadband terminal, the first reference broadcast information comprises a reference control instruction, and the reference control instruction is used for informing the broadband terminal which has responded to the target broadcast information to keep the narrowband communication module of the broadband terminal in a working mode. Because the second broadband narrow-band terminal responds to the target control instruction in the target broadcast information and controls the narrow-band communication module to enter the working mode, the second broadband narrow-band terminal can receive the first reference broadcast information sent by the first broadband narrow-band terminal through the narrow-band communication module of the second broadband narrow-band terminal; correspondingly, the second wide-narrow-band terminal can respond to the reference control instruction in the first reference broadcast information to control the narrow-band communication module to keep in a working mode, so that the second wide-narrow-band terminal and the first wide-narrow-band terminal can normally communicate through a narrow-band network signal.

In practical application, after the first wideband and narrowband terminal sends the target broadcast information through its wideband communication module, it may also not detect whether the own wideband network signal is normal first in a period of time, and in this period of time, the first wideband and narrowband terminal may send the first reference broadcast information through its own narrowband communication module, so that the second wideband and narrowband terminal controls its narrowband communication module to remain in a working mode.

In addition, the second broadband terminal may record the reception time of the target broadcast information or the reference broadcast information each time after receiving the target broadcast information or the reference broadcast information. If the second wideband and narrowband terminal does not receive the target broadcast information or the reference broadcast information within a preset time period after the receiving time of the target broadcast information or the reference broadcast information, and the quality of the wideband network signal of the second wideband and narrowband terminal meets a second preset condition (i.e. the wideband network signal is normal), the second wideband and narrowband terminal can control the narrowband communication module to exit the working mode.

Specifically, if the second wideband/narrowband terminal receives the target broadcast information or the reference broadcast information, and then does not receive the target broadcast information or the reference broadcast information within the preset duration, it is indicated that there is no wideband/narrowband terminal that needs to communicate with the second wideband/narrowband terminal through a narrowband network signal currently; if the broadband network signal of the second broadband and narrowband terminal is also normal, the second broadband and narrowband terminal does not need to communicate with other broadband and narrowband terminals through the narrowband network signal; at this time, the second wideband narrow-band terminal may control its own narrow-band communication module to exit the operation mode, for example, control its narrow-band communication module to switch from the on mode back to the off mode, and for example, control its narrow-band communication module to switch from the wake-up mode back to the sleep mode. Thus, unnecessary power consumption loss caused by long-time operation of the narrow-band communication module of the second wide-narrow-band terminal is avoided.

According to the communication method provided by the embodiment of the application, after a certain broadband and narrowband terminal controls the narrowband communication module to enter the working mode, the target broadcast information is sent through the broadband communication module, so that other broadband and narrowband terminals control the narrowband communication module to enter the working mode, and the broadband and narrowband terminal can normally communicate with other broadband and narrowband terminals through narrowband network signals.

In order to facilitate further understanding of the communication method provided in the embodiment of the present application, the application of the communication method provided in the embodiment of the present application in the narrowband through mode is taken as an example in the following, and the overall exemplary description is given to the communication method provided in the embodiment of the present application, with reference to the schematic diagram of the scenario shown in fig. 3 and the flowchart shown in fig. 4.

When the broadband terminal A detects that the broadband network signal of the broadband terminal A is weakened or unstable, the broadband terminal A can automatically start the narrowband communication module of the broadband terminal A, and meanwhile, target broadcast information is sent to other broadband terminals through the broadband communication module of the broadband terminal A, wherein the target broadcast information comprises positioning information and target control instructions of the broadband terminal A and is used for informing the broadband terminal in a narrowband communication range corresponding to the broadband terminal A to control the narrowband communication module of the broadband terminal A to enter a working mode.

After receiving the target broadcast information through the broadband communication module, the broadband terminal B can calculate the distance L between itself and the broadband terminal A according to the positioning information of the broadband terminal A and the positioning information of itself carried in the target broadcast information. If the distance L is smaller than the communication range of the narrow-band through mode corresponding to the wide-narrow-band terminal A, the wide-narrow-band terminal B needs to respond to the target control instruction in the target broadcast information, and starts the narrow-band communication module of the wide-narrow-band terminal B so as to ensure that the narrow-band communication module of the wide-narrow-band terminal B can carry out emergency communication. If the distance L is larger than the narrow-band communication range corresponding to the wide-band and narrow-band terminal A, the wide-band and narrow-band terminal B cannot communicate with the wide-band and narrow-band terminal A through the narrow-band network signal, so that the wide-band and narrow-band terminal B does not need to start a narrow-band communication module, and waste of power consumption is avoided.

Before the broadband network signal of the broadband and narrowband terminal a returns to normal, the broadband and narrowband terminal a needs to periodically send reference broadcast information to other broadband and narrowband terminals through the narrowband communication module thereof, wherein the reference broadcast information comprises a reference control instruction, and the reference control instruction is used for informing the broadband and narrowband terminal which is positioned in the narrowband communication range corresponding to the broadband and narrowband terminal a and has responded to the target control instruction to control the narrowband communication module thereof to enter the working mode to keep the narrowband communication module thereof in the working mode. Accordingly, the narrowband terminal B, which receives the reference broadcast information through its narrowband communication module, needs to keep its narrowband communication module in an operating mode accordingly.

After the broadband and narrowband terminal A detects that the broadband network signal of the broadband and narrowband terminal A is recovered to be normal, the broadband and narrowband terminal A can stop sending the reference broadcast information through the narrowband communication module; if the wideband and narrowband terminal a does not receive the target broadcast information or the reference broadcast information sent by other wideband and narrowband terminals within the preset period, the wideband and narrowband terminal a can control the narrowband communication module to exit the working mode so as to save power consumption.

If the broadband and narrowband terminal B does not receive the target broadcast information or the reference broadcast information sent by other broadband and narrowband terminals within the preset duration and the broadband network signal of the broadband and narrowband terminal B is normal, the broadband and narrowband terminal B can also automatically control the narrowband communication module to exit the working mode so as to save power consumption.
