Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to an emergency communication coordination method, device and storage medium based on Beidou spatiotemporal data. Background Art

[0002] Emergency communications usually consist of two parts: the communication between the emergency command post and the rear emergency command center, and the emergency command and dispatch communication with the disaster site. The communication between the rear command center and the emergency site usually relies on a satellite communication network, in which a satellite communication vehicle is used at the emergency site; at the disaster site, there are often many people organizing repairs and rescue operations within a wide area (such as a radius of 10km). Therefore, on-site command communications need to rely on a wide-area mobile wireless communication network to establish a mobile or transportable command communication subsystem.

[0003] When natural disasters occur, environmental changes often cause signal instability, which can paralyze the emergency command system and make it impossible to accurately convey disaster rescue instructions. How to ensure signal stability in emergency communication scenarios is a problem that needs to be solved urgently. Summary of the invention

[0045] Figure 2 It is a structural diagram of an emergency communication coordination device based on Beidou spatiotemporal data provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] See also Figure 1 The embodiment of the present invention provides an emergency communication coordination method based on Beidou spatiotemporal data, which may include the following steps:

[0048] S1. Set access rights for the Beidou communication network and identify the user terminals communicating through the Beidou communication network;

[0049] S2. Determine the target emergency communication channel according to the identity identification result of the user terminal, and allow the user terminal to perform emergency communication through the target emergency communication channel;

[0050] S3. Obtain Beidou spatiotemporal data of all user terminals performing emergency communications. When it is determined that the target user terminal has signal attenuation, provide communication coordination services to the target user terminal based on the Beidou spatiotemporal data.

[0051] The present invention monitors the signal strength of user terminals connected to emergency communications, and provides emergency collaborative communication services according to Beidou spatiotemporal data corresponding to the user terminals when the signals are attenuated, thereby ensuring signal stability in emergency communication scenarios.

[0052] In the embodiment of the present invention, further, step S1 may include:

[0053] Establish a user access information database, and after the user terminal completes the personal information verification, import the personal basic information corresponding to the user terminal into the user access information database;

[0054] In response to an emergency communication access request from a user terminal, read basic personal information in the emergency communication access request;

[0055] Match personal basic information based on the user access information database;

[0056] If the information corresponding to the basic personal information is matched, the identity verification result of the user terminal is determined to be a successful match;

[0057] If no information corresponding to the personal basic information is matched, the identity verification result of the user terminal is determined to be a match failure.

[0058] It should be noted that, based on the pre-established user access information database, the identity information of the user terminal applying for access to emergency communications can be verified. If the corresponding information is matched in the user access information database, the identity authentication of the user terminal is successful, and the user terminal can be provided with a normal emergency communication channel for emergency communication; conversely, if the corresponding information is not matched in the user access information database, the identity authentication of the user terminal fails, and it is marked as a temporary communication user, and a temporary emergency communication channel can be provided to the user terminal for emergency communication.

[0059] In the embodiment of the present invention, further, the user terminal completes the process of personal information verification, including:

[0060] Obtaining basic personal information input by the user terminal through the information registration unit;

[0061] After the personal basic information is reviewed and approved, a user identity identification sequence is generated based on the mobile phone number in the personal basic information;

[0062] The user identity recognition sequence is bound to the basic personal information and imported into the user access information database; at the same time, the user identity recognition sequence is fed back to the user terminal corresponding to the basic personal information.

[0063] It should be noted that basic personal information may include name, gender, age, ID card information and real-name authenticated mobile phone number; the review of basic personal information may be based on preset review rules to determine whether the user's information meets the corresponding conditions, and if it meets the conditions, it will be reviewed and approved.

[0064] In the embodiment of the present invention, further, step S2 may include:

[0065] If it is determined that the identity identification result of the user terminal is a successful match, the normal emergency communication channel in an idle state is determined as the target emergency communication channel;

[0066] If it is determined that the identity identification result of the user terminal is a match failure, the temporary emergency communication channel in an idle state is determined as the target emergency communication channel;

[0067] Allow user terminals to conduct emergency communications through the target emergency communication channel.

[0068] It should be noted that the emergency communication channels include several normal emergency communication channels and several temporary emergency communication channels. The states of the emergency communication channels include occupied state and idle state. Among them, the normal emergency communication channels are open to users who have passed identity verification, so that users with access rights can carry out more reliable and stable communications; the temporary emergency communication channels are open to users who have not passed identity verification, so that users who do not have access rights can obtain convenient temporary emergency communication channels, which is convenient for users in certain emergency situations to communicate.

[0069] In the embodiment of the present invention, further, step S3 includes:

[0070] Obtaining the location information of each user terminal performing emergency communications and periodically updating the location information;

[0071] Acquire the signal strength of the user terminal according to the periodically updated update time, and generate a signal strength change curve of the user terminal according to the update time and the signal strength;

[0072] Perform signal attenuation detection on each user terminal according to the relationship between the signal strength change curve and the preset signal strength threshold line;

[0073] When it is determined that the target user terminal has signal attenuation, the candidate communication base station corresponding to the location information of the target user terminal when the signal attenuation occurs is retrieved, and a cooperative communication instruction is sent to the candidate communication base station so that the candidate communication base station can cooperate with the target user terminal.

[0074] It should be noted that, according to the Beidou spatiotemporal data of the user terminal, the corresponding relationship between the position and time of the user terminal can be determined. At the same time, the signal strength of the user terminal is obtained at each time node, and a two-dimensional coordinate system of time with respect to the signal strength is established, and a signal strength change curve can be generated; a signal strength threshold line is set in the two-dimensional coordinate system, and the strength of the mobile phone signal is judged according to the relationship between the signal strength change curve and the signal strength threshold line. When it is judged that the mobile phone signal is attenuated, a cooperative communication service is provided to the user terminal. Specifically, according to the position of the user terminal when the signal attenuation occurs, the candidate communication base stations (which may be one or more) within a certain range of the position that can provide signals for it are searched, and cooperative communication instructions are sent to these candidate communication base stations so that the candidate communication base stations can perform cooperative communication with the user terminal. It can be understood that when there are multiple candidate communication base stations, the user terminal can select a base station with the strongest signal for communication access.

[0075] In the embodiment of the present invention, further, according to the relationship between the signal strength variation curve and the preset signal strength threshold line, signal attenuation detection is performed on each user terminal, including:

[0076] When it is determined that the current signal strength of the user terminal is less than the signal strength corresponding to the signal strength threshold line, a first moment corresponding to the current signal strength of the user terminal is obtained, and a second moment after a preset time period and with the first moment as the starting point is obtained;

[0077] Determine a signal evaluation coefficient of the user terminal within a preset time period based on a signal strength change curve between a first moment and a second moment;

[0078] When it is determined that the signal evaluation coefficient of the user terminal within the preset time period exceeds a preset signal evaluation coefficient threshold, it is determined that signal attenuation occurs in the user terminal.

[0079] It should be noted that when the signal strength of the user terminal at a certain moment is less than the preset threshold, the moment is taken as the starting point, and the signal strength for a preset time period t is continuously obtained. The signal evaluation coefficient of the user terminal in the preset time period can be determined based on the signal strength change curve during this period. According to the relationship between the signal evaluation coefficient and the preset signal evaluation coefficient threshold, it is determined whether the user terminal has signal attenuation during the time period. If no signal attenuation occurs, it means that the reason for the weak signal strength of the user terminal is signal fluctuation, and there is no need for collaborative communication services.

[0080] In the embodiment of the present invention, further, when it is determined that the target user terminal has signal attenuation, retrieving the candidate communication base station corresponding to the location information of the target user terminal when the signal attenuation occurs, and sending a cooperative communication instruction to the candidate communication base station so that the candidate communication base station performs cooperative communication with the target user terminal, including:

[0081] When it is determined that the target user terminal has signal attenuation, searching for candidate communication base stations within a preset range according to the location information of the target user terminal when the signal attenuation occurs; wherein the target user terminal is within the signal coverage range of the candidate communication base stations;

[0082] A cooperative communication instruction is sent to the candidate communication base station so that the candidate communication base station performs cooperative communication with the target user terminal.

[0083] It should be noted that the location where the user terminal experiences signal attenuation can be used as the center to retrieve available communication base stations within a certain range, and if the signal coverage ranges of these available communication base stations can cover the user terminal, the available communication base stations that meet the conditions will be determined as candidate communication base stations, and cooperative communication instructions will be sent to these candidate communication base stations so that the candidate communication base stations can perform cooperative communication with the user terminal.

[0084] In an embodiment of the present invention, further, the emergency communication coordination method based on Beidou spatiotemporal data also includes:

[0085] When it is determined that the target user terminal has signal attenuation, an early warning message is generated and fed back to the target user terminal.

[0086] It is understandable that when it is determined that the signal attenuation occurs in the user terminal, warning information is generated and fed back to the user terminal so that the user can be reminded to avoid entering the no-signal area.

[0087] Based on the above scheme, in order to better understand the emergency communication coordination method based on Beidou spatiotemporal data provided by the embodiment of the present invention, the following is a detailed description:

[0088] The embodiment of the present invention can be implemented by the following steps:

[0089] Step 1: Set access permissions for the Beidou communication network and identify users who communicate through the Beidou communication network;

[0090] It should be further explained that, in the specific implementation process, the process of identifying the user communicating through the Beidou communication network includes:

[0091] Establish a user access information database, and import the user's basic personal information into the user access information database after the user completes personal information verification;

[0092] It should be further explained that, in the specific implementation process, the process of users completing personal information verification includes:

[0093] An information registration unit is provided, through which the user inputs basic personal information, and the input basic personal information is reviewed, and the review result is output; wherein the basic personal information may include name, gender, age, ID card information, and real-name authenticated mobile phone number;

[0094] After the review is passed, a user identity identification sequence is generated according to the mobile phone number in the input personal basic information, and the generated user identity identification sequence is bound and associated with the user's personal basic information, and the generated user identity identification sequence is fed back to the user's mobile phone terminal;

[0095] Import the user's basic personal information and user identity identification sequence into the user access information database.

[0096] Granting communication access rights to users in the user access information database to communicate through the Beidou communication network;

[0097] After obtaining the communication access rights of the Beidou communication network, send emergency signals to the Beidou communication network through mobile terminals;

[0098] Based on the received emergency signal, an emergency communication access request is generated, the personal basic information of the user corresponding to the emergency communication access request is read, and the read user basic information is matched with the personal basic information of the user in the user access information database. If the same personal basic information exists in the user access information database, the match is successful, otherwise the match fails, and the user whose matching fails is marked as a temporary communication user.

[0099] Step 2: Establish an emergency communication channel and select communication access for the emergency communication channel;

[0100] Specifically, the emergency communication channel includes several normal emergency communication channels and several temporary emergency communication channels, and reads whether there is a corresponding user identity identification sequence according to the received emergency communication access request; it should be further explained that in the specific implementation process, the state of the emergency communication channel includes an occupied state and an idle state;

[0101] If it exists, then according to the read user identity identification sequence, select the idle state emergency communication channel to communicate with the mobile terminal corresponding to the user identity identification sequence, and read the spatiotemporal data of the mobile terminal;

[0102] If it does not exist, a temporary emergency communication channel in an idle state is selected to establish a communication connection with the mobile terminal corresponding to the emergency signal, and the spatiotemporal data of the mobile terminal is read.

[0103] Step 3: Obtain the spatiotemporal data of users accessing the emergency communication channel and select the communication coordination range of the emergency communication channel;

[0104] It should be further explained that, in the specific implementation process, the specific process of obtaining the spatiotemporal data of users accessing the emergency communication channel includes:

[0105] After establishing a communication connection with the mobile terminal, the location of the mobile terminal is obtained and the location of the mobile terminal is periodically updated;

[0106] The location of the mobile terminal can be marked on the map, and the update time can be bound and associated with the location of each update;

[0107] Acquire the signal strength of the mobile terminal according to the update time, and generate a signal strength change curve according to the acquired signal strength of the mobile terminal;

[0108] Establishing a two-dimensional coordinate system of time with respect to signal strength, and mapping the generated signal strength variation curve into the two-dimensional coordinate system;

[0109] A signal strength threshold line is set in a two-dimensional coordinate system, and the strength of the mobile phone signal is judged according to the relationship between the signal strength change curve and the signal strength threshold line;

[0110] Specifically, the acquired mobile phone signal strength is recorded as XQ, and the signal strength corresponding to the signal strength threshold line is recorded as X0;

[0111] When XQ>X0, it means that the mobile phone signal strength is normal, otherwise when XQ≤X0, it means that the mobile phone signal strength is weak;

[0112] When the mobile phone signal strength is weak, a first time axis is generated, and the time corresponding to the first time axis is recorded as t1;

[0113] Taking the time corresponding to the first time axis as the starting time, and continuously acquiring the signal of the mobile terminal for a time length of t, generating a signal strength change curve in the time period, and generating a second time axis at the same time, and recording the time corresponding to the second time axis as t2;

[0114] Then the signal evaluation coefficient of the mobile phone terminal between the first time axis and the second time axis is obtained, and the signal evaluation coefficient is recorded as XP;

[0115] The calculation method of XP can be obtained by the following formula:

[0116]

[0117] When XP<P0, it means that the reason for the weak mobile phone signal strength is signal fluctuation;

[0118] When XP≥P0, it means that the mobile phone signal strength is attenuated, and an early warning message is generated and fed back to the mobile phone terminal to remind the user to avoid entering the no-signal area; P0 is the system preset signal evaluation coefficient threshold;

[0119] According to the early warning information, a collaborative communication instruction is generated, and the available communication base stations within the search range are searched with the current location of the mobile terminal as the center, and the collaborative communication instruction is sent to all communication base stations; it should be further explained that in the specific implementation process, the search range depends on the signal coverage range of the communication base station, that is, when the current location of the mobile terminal is within the signal coverage range of the communication base station, the communication base station can receive the collaborative communication instruction;

[0120] After receiving the collaborative communication instruction, the communication base station actively establishes a communication connection with the mobile phone terminal; if there are multiple communication base stations communicating with the mobile phone terminal at the same time, the communication base station with the highest signal strength is preferentially selected to connect with the mobile phone.

[0121] It should be noted that, for the above method or process embodiments, for the sake of simplicity, they are all described as a series of action combinations, but those skilled in the art should know that the embodiments of the present invention are not limited by the described action sequence, because according to the embodiments of the present invention, certain steps can be performed in other sequences or simultaneously. Secondly, those skilled in the art should also know that the embodiments described in the specification are all optional embodiments, and the actions involved are not necessarily required by the embodiments of the present invention.
