Description

Technical Field

[0001] The invention belongs to the technical field of satellite communication applications, and in particular relates to a Tiantong terminal dispatching management system and method. Background Art

[0002] Tiantong satellite has achieved full coverage in my country and has the advantage of not being restricted by ground networks. It is a guaranteed communication means in the "three cuts" scenario of power outage, network outage, and road outage, and is widely used in emergency fields.

[0003] Although the Tiantong satellite communication method has played a huge role in emergency rescue scenarios, there are still some problems: (1) The Tiantong terminal needs to be in a satellite-pointing state when in use, and is more suitable as a call initiator. In emergency rescue scenarios, it is more common for the command center to call the Tiantong terminal, which requires the command center to be able to grasp the online status of the Tiantong terminal in real time; although Tiantong satellite communication supports SMS, voice and narrowband data functions, due to the high Tiantong tariff, most Tiantong terminals do not have data functions, and the duration of SMS and voice calls is also very limited. Therefore, the emergency management department cannot conduct timely status monitoring and command and dispatch of the Tiantong terminal, and there is a "cannot see" problem. (2) Tiantong satellites are geosynchronous orbit satellites that cover the ground through spot beams. The coverage diameter of each spot beam on the ground is hundreds of kilometers. The terminal user capacity and the number of concurrent calls of each spot beam are very limited. In the event of an emergency, the sudden surge in Tiantong business volume will cause the terminal to drop the network, the call to fail, and the "call cannot be connected" problem. (3) Tiantong satellite is operated by operators and does not support common command and dispatch functions in the emergency communications industry, such as location reporting, environmental monitoring, forced demolition, and silence, resulting in the problem of "not being able to be adjusted". Summary of the invention

[0004] In response to the needs of equipment status monitoring and command and dispatch in the field of emergency communications, the present invention provides a Tiantong terminal dispatch management system and method. While supporting Beidou short messages and Tiantong voice services, the system can control Tiantong terminals through Beidou short messages, thereby achieving efficient command and dispatch in emergency rescue scenarios.

[0005] The present invention is achieved through the following technical solutions:

[0006] A Tiantong terminal dispatching and management system, comprising a dispatching platform and a fusion terminal;

[0007] The dispatching platform includes a Beidou short message transceiver module, a device management module, a command processing module, a command and dispatch module and an external interface module; wherein the Beidou short message transceiver module is used to interact with the fusion terminal for Beidou short messages, and is responsible for the encapsulation and transceiver of Beidou short messages; the device management module can display the device information of all fusion terminals registered on this platform, including the terminal Tiantong number and short message number, the department to which the terminal belongs, the terminal location, the terminal Tiantong network status, the terminal beam number, and the priority, and can also display the call status of the fusion terminal, including whether a Tiantong call is in progress, The time of the last Tiantong call; the command processing module is used to encapsulate and parse the control commands, and to exchange information with the equipment management module and the Beidou short message receiving and sending module; the command and dispatch module can communicate with the fusion terminal, including sending and receiving Beidou short messages, sending and receiving Tiantong text messages, and making and receiving Tiantong calls. It can also command and dispatch the fusion terminal, including batch broadcasting, batch inspections, priority adjustment, forced demolition of calls, silent mode control, environmental monitoring, etc.; the external interface module is responsible for communicating with external equipment, including Beidou command machine interface, wired telephone interface, Tiantong telephone terminal interface and network port.

[0008] The fusion terminal includes a Beidou short message module, a Tiantong module, a terminal instruction processing module and a business processing module. The Beidou short message module is responsible for sending and receiving Beidou short messages; the Tiantong module is used for sending and receiving Tiantong text messages and voice; the terminal instruction processing module is responsible for the encapsulation and parsing of control instructions; the business processing module is responsible for the business control of the fusion terminal, including the execution of control instructions, the editing and display of short messages / short messages, and the reception and making of Tiantong voices.

[0009] The dispatching platform communicates with the fusion terminal via Beidou short message satellite and Tiantong satellite.

[0010] Furthermore, each fusion terminal has a unique designated identifier, and the designated identifier is used by the scheduling platform to uniquely identify the fusion terminal.

[0011] Furthermore, the fusion terminal reports the device information and status information of the terminal through the status synchronization instruction; the service processing module of the fusion terminal regularly detects the status of the Tiantong module and the Beidou short message module, and encapsulates the device information, Tiantong online status, call status, call request and other information into a status synchronization instruction through the terminal instruction processing module, and then uses the Beidou short message module to encapsulate the status synchronization instruction into a short message and send it to the dispatching platform through the Beidou satellite. In order to ensure the connection status between the fusion terminal and the dispatching platform, the fusion terminal will periodically send a heartbeat type status synchronization instruction to the dispatching platform.

[0012] The dispatch platform controls the fusion terminal through dispatch instructions; the command and dispatch module of the dispatch platform queries the status of the fusion terminal through the device management status, and sends the environment listening instruction, forced demolition instruction, silent mode instruction, call priority configuration instruction, etc. to the instruction processing module according to the dispatch requirements to be encapsulated as a dispatch instruction, and then sends it to the Beidou command machine through the short message transceiver module and the external interface module, and the Beidou command machine sends it to the fusion terminal through the Beidou satellite. The dispatch platform has the function of sending dispatch instructions in batches.

[0013] The specific process of Tiantong voice call control is as follows:

[0014] When the fusion terminal shows that Tiantong has successfully entered the network, but cannot initiate a Tiantong call, the user chooses to initiate a Tiantong call application request to the dispatching platform through the fusion terminal; the business processing module sends the Tiantong call application message to the terminal instruction processing module; after receiving the message, the terminal instruction processing module encapsulates it into a Tiantong call application instruction according to the format, and sends the encapsulated application instruction to the Beidou short message module. The Beidou short message module re-encapsulates the Tiantong call application instruction in the short message format and sends it to the Beidou satellite;

[0015] The Beidou satellite forwards the short message to the Beidou command machine connected to the dispatching platform. The Beidou short message transceiver module of the dispatching platform receives the short message through the external interface module, and sends the short message to the instruction processing module after parsing. The instruction processing module parses the call application instruction and sends the call application message to the command and dispatch module of the dispatching platform. The command and dispatch personnel decide whether to approve the call application of the fusion terminal after querying the current Tiantong channel occupancy and the priority of the application terminal through the equipment management module.

[0016] If the application of the fusion terminal is approved, a call application success instruction will be issued to the applying fusion terminal: the application success instruction is sent by the command and dispatch module to the instruction processing module; the instruction processing module encapsulates the application success message in the message result feedback instruction and sends it to the Beidou short message transceiver module; the Beidou short message transceiver module encapsulates it into a short message and then sends it to the Beidou satellite by the Beidou command machine; the Beidou short message module of the fusion terminal parses the received short message and sends it to the terminal instruction processing module. The terminal instruction processing module parses the application success instruction and sends it to the business processing module, and the business processing module notifies the user that the application is successful.

[0017] Furthermore, the control instruction has a fixed frame format, and the fixed frame format includes a frame header, an encryption identifier, a message ID, a message time, a message type, a message content and a check bit.

[0018] Furthermore, the message type includes terminal startup type, status type, heartbeat type, environment listening type, forced demolition type, silent mode type, call priority configuration type, call application type and message result feedback type;

[0019] The fusion terminal uses the terminal startup type command to notify the dispatching platform that the current fusion terminal is online;

[0020] The command of the integrated terminal usage status type notifies the dispatching platform of the change of the current terminal service status;

[0021] The fusion terminal uses heartbeat type instructions to maintain the online status of the fusion terminal on the scheduling platform;

[0022] The dispatching platform uses environment monitoring type instructions to monitor the environment of the fusion terminal. When the dispatching platform monitors the environment of the fusion terminal, the fusion terminal and the dispatching platform automatically establish a communication channel. The fusion terminal only collects sound but does not play it. The dispatching platform can monitor the real-time status of the external environment of the fusion terminal.

[0023] The dispatching platform uses a forced demolition type command to forcibly demolish the Tiantong call of the fusion terminal;

[0024] The dispatching platform uses the silent mode type command to force the converged terminal to be silent. The converged terminal cannot initiate a call service when it is in silent mode;

[0025] The dispatching platform uses call priority configuration type instructions to synchronize the service priority of the converged terminal;

[0026] When the converged terminal cannot initiate the Tiantong service, it can apply for the Tiantong call service to the dispatching platform through the call application type;

[0027] After receiving the business-related control instructions, the scheduling platform and the fusion terminal use the message result feedback type to provide ACK feedback.

[0028] A Tiantong terminal dispatching management method, characterized in that it is implemented by a Tiantong terminal dispatching management system as described above, and the specific process is as follows:

[0029] The fusion terminal is configured in different areas, and the command center configures the dispatching platform. After the fusion terminal is turned on, it sends a status synchronization command to the dispatching platform to report the device status. After receiving the message, the dispatching platform records it locally and updates the device status in the device management module.

[0030] After the fusion terminal is turned on, it sends a heartbeat command to the dispatching platform regularly. If it fails to receive the terminal's heartbeat command or other status synchronization command within the specified time, the dispatching platform considers the terminal to be offline. The device management module of the dispatching platform indicates the terminal's online status. If the fusion terminal's Tiantong call status changes, it sends a status command to the dispatching platform, and the dispatching platform can determine the fusion terminal's call status in real time.

[0031] The call priority configuration command is sent from the dispatch platform to the fusion terminal; the dispatch platform determines the importance of the terminal service based on the call priority, which is used in conjunction with the forced demolition command; the command dispatcher can adjust the terminal priority in real time according to the on-site situation;

[0032] In addition to status instructions, heartbeat instructions, and message result feedback instructions, the message receiver should use the message result feedback instruction as an ACK reply to the message sender after receiving the control instruction.

[0033] Furthermore, the environment listening instruction is used by the platform side to perceive the environment in which the terminal is located through Tiantong voice; the dispatching command user can hear the sound on the fusion terminal side, but the fusion terminal side cannot hear the sound on the command side.

[0034] Furthermore, when an emergency situation causes the Tiantong service channel to be tight, a forced demolition command is used to hang up the Tiantong call service of the low-priority terminal to release the service channel to ensure the high-priority service;

[0035] When a specific area is in an emergency, the silent mode command can be used temporarily to silence the fusion terminals in other areas; terminals in silent mode cannot initiate Tiantong calls and Tiantong text messages, thereby reducing the occupation of Tiantong business channels;

[0036] If the fusion terminal cannot initiate a Tiantong call due to insufficient Tiantong channel resources or silence, it can apply to the dispatching platform to initiate a Tiantong call through a call application instruction.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] Through BeiDou-3 short messages, the Tiantong terminal can be controlled, and the real-time monitoring of the equipment status and location of the Tiantong terminal can be realized, as well as the dispatching functions such as terminal silencing, environmental monitoring, business priority control, and forced demolition. Through the above structure, the emergency management department can accurately grasp the location of emergency rescue personnel and the equipment status of the Tiantong terminal without relying on the ground operator network, effectively conduct command and dispatch, and ensure the availability of the Tiantong terminal in emergencies; at the same time, through the two satellite communication means of BeiDou short messages and Tiantong satellite communication, the communication is smooth, and the efficiency of emergency rescue is improved.

[0042] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0043] A Tiantong terminal dispatching and management system, characterized in that the dispatching platform uses BeiDou-3 short messages to perform equipment status detection and command dispatch on the fusion terminal;

[0044] The dispatching platform has the ability to communicate with Tiantong and the control function of Beidou command machine. The dispatching platform has a special interactive interface, which is managed by the command and dispatch personnel and controls all fusion terminals. The control signaling is encapsulated and sent via Beidou short message. After receiving it, the fusion terminal can perform corresponding operations on the Tiantong module.

[0045] The fusion terminal has the capability of receiving and sending short messages of BeiDou-3 and the capability of voice and data communication of TianTong. The fusion terminals and the dispatching platform can communicate with each other through TianTong satellite or BeiDou satellite. The fusion terminal has a unique designated identifier, which is used by the dispatching platform to distinguish the terminals.

[0046] Optionally, the scheduling platform has a secure login password.

[0047] Optionally, the dispatching platform has the functions of terminal information entry and grouping, can add, delete, modify and check terminal groups and basic information, and can configure the priority of the terminal.

[0048] If a natural disaster causes a "three-outage" situation (power outage, network outage, and circuit breakage), the dispatching platform can conduct a Tiantong voice call with the on-site fusion terminal holder. The command and dispatch personnel can control the service priority and working mode of all fusion terminals through management and control signaling, so that high-priority Tiantong calls are guaranteed.

[0049] A Tiantong terminal dispatching management method, the method needs to further encapsulate the Beidou-3 short message content into a control instruction. The control instruction can be parsed and encapsulated by the dispatching platform and the fusion terminal.

[0050] Management and control instructions are divided into status synchronization instructions and scheduling instructions, including heartbeat instructions, environment listening instructions, forced demolition instructions, silent mode instructions, call priority configuration instructions, and call service application instructions.

[0051] The status synchronization instructions include power-on notification instructions, status reporting instructions, heartbeat instructions and other similar function information notification instructions.

[0052] After the fusion terminal is turned on, it sends a power-on notification command to the dispatching platform. The notification content includes the terminal's unique identifier, Tiantong number, Beidou number, Beidou short message service frequency, and Beidou short message communication level. After receiving the notification, the dispatching platform replies ACK to the designated terminal.

[0053] The fusion terminal will regularly report the current terminal information to the dispatching platform. The information includes the terminal's unique identifier, the terminal's current call status, terminal environment data, terminal silent status, etc., which can be flexibly configured according to actual conditions.

[0054] Optionally, the scheduling platform may actively pull up terminal information consistent with the above notification of the terminal.

[0055] The fusion terminal will periodically send heartbeat commands to maintain the terminal online status.

[0056] Optionally, other state synchronization instructions may be sent as heartbeat instructions or combined with the heartbeat instructions.

[0057] The forced demolition instruction, silent mode instruction, call priority configuration instruction, and call service application instruction are used to enable and disable the Tiantong voice function of the fusion terminal.

[0058] Optionally, the control instruction has an encryption mark, and whether encryption processing is required is determined according to security requirements. Instruction parsing is to determine whether parsing is required based on the encryption mark.

[0059] Optionally, the control instruction has a message content field, and whether the message content field is required is determined based on the message type.

[0060] Optionally, the control instruction has a time identification field, and whether it is necessary to carry the message sending time is determined according to actual conditions.

[0061] The dispatching platform can summarize the current service status of all integrated terminals and sense the busyness of the Tiantong satellite voice service in the current system.

[0062] When the Tiantong service channel is full, the dispatching platform can forcibly close the Tiantong call of the designated fusion terminal through a forced demolition command.

[0063] If the converged terminal cannot initiate a call for a long time, it can actively apply to the system. The system can release the low-priority call through a forced release command and reply the result to the applying terminal through a short message. The terminal whose call is released can receive the reason for the service termination through a short message.

[0064] The dispatching platform can open the silent mode of the converged terminal once or in batches. The converged terminal in silent mode cannot actively initiate Tiantong voice services.

[0065] By forcibly removing the call and silent mode of the designated terminal, it can be ensured that there are available service channels in the current system for higher priority voice calls. The system can exit the silent mode of designated terminals and batches of terminals, and the terminals that have been unrestricted can initiate Tiantong services normally.

[0066] The environment monitoring instruction is used to perform environment perception on the fusion terminal of the specified number.

[0067] In case of emergencies, the terminal can implement a one-way voice call function in the background through the environment listening command without the user's awareness. After turning on the environment listening, the terminal microphone is always in an occupied state, and the dispatch platform can perceive the real-time situation on the scene through voice.

[0068] Reference Figure 1 A Tiantong terminal dispatching and management system includes a dispatching platform and a fusion terminal.

The dispatching platform can communicate with the fusion terminal through Beidou short messages via the Beidou command machine, make Tiantong voice calls with the fusion terminal through wired telephones, Tiantong terminals or Internet phone devices, and communicate with the fusion terminal through the Internet.

[0075] Reference Figure 3 The integrated terminal should include Beidou short message module, Tiantong module, terminal command processing module and business processing module.

[0076] The Beidou short message module is responsible for sending and receiving Beidou short messages.

[0077] The Tiantong module is used for sending and receiving Tiantong text messages and voice.

[0078] The terminal instruction processing module is responsible for the encapsulation and parsing of control instructions.

[0079] The business processing module is responsible for the business control of the integrated terminal, including the execution of management and control instructions, the editing and display of short messages / text messages, and the making and receiving of Tiantong voice calls.

[0080] The specific steps are explained using Tiantong call application as an example.

[0081] The terminal operation user sees that the Tiantong network is successfully connected, but cannot initiate a Tiantong call. The terminal sends a Tiantong call application message to the terminal instruction processing module through the business processing module;

[0082] After receiving the message, the terminal instruction processing module encapsulates it into a Tiantong call application instruction according to the format;

[0083] The terminal command processing module sends the encapsulated application command to the Beidou short message module;

[0084] The Beidou short message module repackages the Tiantong call application instruction in the short message format and sends it to the Beidou satellite;

[0085] The Beidou satellite forwards the short message to the Beidou control machine connected to the dispatching platform, and the Beidou short message transceiver module of the dispatching platform receives the short message forwarded by the Beidou control machine through the external interface module;

[0086] The Beidou short message transceiver module completes the short message parsing and sends it to the command processing module;

[0087] The instruction processing module parses the call application instruction and sends the call application message to the command and dispatch module of the dispatch platform;

[0088] The command and dispatch personnel use the equipment management module to query the current occupancy of the Tiantong channel and the priority of the application terminal, and then decide whether to approve the call application of the fusion terminal;

[0089] The terminal application is approved, and the successful application instruction is sent from the command and dispatch module to the instruction processing module;

[0090] The command processing module encapsulates the application success message in the message result feedback command and sends it to the Beidou short message transceiver module;

[0091] The Beidou short message transceiver module encapsulates the short message into a short message and then sends it to the Beidou satellite by the Beidou control machine;

[0092] The Beidou short message module of the fusion terminal parses the received short message and sends it to the terminal command processing module;

[0093] The terminal instruction processing module parses the successful application instruction and sends it to the business processing module, which notifies the user that the application is successful;

[0094] The user of the converged terminal initiates a Tiantong call.

[0095] The embodiment of the present application also adopts a Tiantong terminal scheduling management method, and the specific steps are as follows:

[0096] Step 1: The frame format of the control command is specified. The control command frame format includes the following parts:

[0097] The frame header is used to identify control instructions. Short message content that does not meet the frame header requirements is treated as a normal short message;

[0098] Message ID: Message ID is used to identify the message sequence and is used for message history tracing and feedback message matching;

[0099] Message type, indicating the type of control instruction message, including but not limited to terminal startup type, status type, heartbeat type, environment listening type, forced demolition type, silent mode type, call priority configuration type, call application type, and message result feedback type;

[0100] Check digit, used to determine message integrity;

[0101] Optionally, the encryption identifier is determined to be required based on security requirements;

[0102] Optionally, the message content is determined to be sufficient based on the message type. If the message content is required, the message length must be carried;

[0103] Optionally, whether the time stamp is required is determined based on actual conditions.

[0104] Step 2: Configure fusion terminals in different areas and configure the dispatching platform in the command center.

[0105] Step 3: After the terminal is powered on, it sends a terminal power-on command to the dispatching platform to report the device status. The terminal power-on command should include the terminal unique identifier, terminal Tiantong number, terminal Tiantong registered beam number, terminal Beidou number, terminal Beidou service frequency, and terminal Beidou communication length level. After receiving the power-on message, the platform records it locally and updates the status in the device management module.

[0106] Step 4: After the terminal is turned on, it sends a heartbeat command to the dispatching platform regularly. If the terminal heartbeat command or other message command is not received within the timeout period, the dispatching platform considers that the terminal is offline. The dispatching platform device management module updates the terminal online status.

[0107] Step 5: When the terminal Tiantong call status changes, a status instruction is sent to the dispatching platform, and the dispatching platform can determine the terminal call status in real time.

[0108] Step 6: The environment listening command is used by the platform side to perceive the environment of the terminal through the Tiantong voice. After the environment listening is connected, the dispatching command user can hear the sound on the terminal side, but the terminal side cannot hear the sound on the command side.

[0109] Step 7: The dispatch platform sends the call priority configuration command to the terminal. The dispatch platform determines the importance of the terminal service based on the call priority, which is used in conjunction with the demolition command. The dispatcher can adjust the terminal priority in real time according to the on-site situation.

[0110] Step 7: When the Tiantong service channel is in short supply due to an emergency, use a forced removal command to disconnect the Tiantong call service of the low-priority terminal to release the service channel and ensure that high-priority services are carried out.

[0111] Step 8. When the situation in a specific area is urgent, the silent mode command can be used temporarily to silence the fusion terminals in other areas; terminals in silent mode cannot initiate Tiantong calls and Tiantong text messages, thereby reducing the occupancy of Tiantong business channels.

[0112] Step nine: If the fusion terminal cannot initiate a Tiantong call due to insufficient Tiantong resources or silence, it can apply to the dispatching platform through a call application instruction if it needs to initiate a Tiantong call.

[0113] Step nine, in addition to the status command, heartbeat command, and message result feedback command, the message receiver should use the message result feedback command as an ACK reply to the message sender after receiving the control command.

[0114] Obviously, those skilled in the art should understand that the above modules or steps of the present application can be implemented by a general computing device, they can be concentrated on a single computing device, or distributed on a network composed of multiple computing devices. Optionally, they can be implemented by executable program code, so that they can be stored in a computing device with a storage device for execution, or they can be made into individual integrated circuit modules, or multiple modules or steps therein can be made into a single integrated circuit module for implementation. In this way, the present application is not limited to any specific hardware and software combination.

If the application of the fusion terminal is approved, a call application success instruction will be issued to the applying fusion terminal: the application success instruction is sent by the command and dispatch module to the instruction processing module; the instruction processing module encapsulates the application success message in the message result feedback instruction and sends it to the Beidou short message transceiver module; the Beidou short message transceiver module encapsulates it into a short message and then sends it to the Beidou satellite by the Beidou command machine; the Beidou short message module of the fusion terminal parses the received short message and sends it to the terminal instruction processing module. The terminal instruction processing module parses the application success instruction and sends it to the business processing module, and the business processing module notifies the user that the application is successful.

2. A Tiantong terminal dispatching and management system according to claim 1, characterized in that: Each fusion terminal has a unique designated identifier, which is used by the scheduling platform to uniquely identify the fusion terminal.

3. A Tiantong terminal dispatching and management system according to claim 1, characterized in that: The control instruction has a fixed frame format, and the fixed frame format includes a frame header, an encryption identifier, a message ID, a message time, a message type, a message content and a check bit.

4. A Tiantong terminal dispatching and management system according to claim 3, characterized in that: Message types include terminal startup type, status type, heartbeat type, environment listening type, forced demolition type, silent mode type, call priority configuration type, call application type and message result feedback type; The fusion terminal uses the terminal startup type command to notify the dispatching platform that the current fusion terminal is online; The command of the integrated terminal usage status type notifies the dispatching platform of the change of the current terminal service status; The fusion terminal uses heartbeat type instructions to maintain the online status of the fusion terminal on the scheduling platform; The dispatching platform uses environment monitoring type instructions to monitor the environment of the fusion terminal; The dispatching platform monitors the environment of the fusion terminal. The fusion terminal and the dispatching platform automatically establish a daily communication. The fusion terminal only collects sound, and the dispatching platform can monitor the real-time status of the external environment of the fusion terminal. The dispatching platform uses a forced demolition type command to forcibly demolish the Tiantong call of the fusion terminal; The scheduling platform uses silent mode type instructions to force the fusion terminal to be silent; The converged terminal cannot initiate a call service when it is in silent mode; The dispatching platform uses call priority configuration type instructions to synchronize the service priority of the converged terminal; When the fusion terminal cannot initiate the Tiantong service, it can apply for the Tiantong call service to the dispatching platform through a call application type instruction; After receiving the scheduling instruction, the scheduling platform and the fusion terminal both use the message result feedback type instruction to provide ACK feedback.

5. A Tiantong terminal dispatching management method, characterized in that: It is implemented by a Tiantong terminal dispatching management system as claimed in claim 4, and the specific process is as follows: The fusion terminal is configured in different areas, and the command center configures the dispatching platform. After the fusion terminal is turned on, it sends a status synchronization command to the dispatching platform to report the device status. After receiving the message, the dispatching platform records it locally and updates the device status in the device management module. After the fusion terminal is turned on, it sends heartbeat instructions to the dispatching platform at regular intervals. If the terminal heartbeat instructions or other status synchronization instructions are not received within the specified time, the dispatching platform considers the terminal to be offline; the equipment management module of the dispatching platform indicates the terminal online status; when the Tiantong call status of the fusion terminal changes, it sends a status instruction to the dispatching platform, and the dispatching platform can determine the call status of the fusion terminal in real time; The call priority configuration instruction is sent by the dispatching platform to the fusion terminal; the dispatching platform determines the importance of the terminal service according to the call priority, which is used in conjunction with the forced demolition instruction; Command and dispatch personnel can adjust the terminal priority in real time according to the on-site situation; In addition to status instructions, heartbeat instructions, and message result feedback instructions, the message receiver should use the message result feedback instruction as an ACK reply to the message sender after receiving the control instruction.

6. A Tiantong terminal dispatching management method according to claim 5, characterized in that: The environment listening command is used by the platform side to perceive the terminal environment through Tiantong voice; the dispatching command user can hear the sound on the fusion terminal side, but the fusion terminal side cannot hear the sound on the command side.

7. A Tiantong terminal dispatching management method according to claim 5, characterized in that: When the Tiantong service channel is tight due to an emergency, use the forced removal command to hang up the Tiantong call service of the low-priority terminal to release the service channel to ensure the high-priority service; When a specific area is in an emergency, the silent mode command can be used temporarily to silence the fusion terminals in other areas; terminals in silent mode cannot initiate Tiantong calls and Tiantong text messages, thereby reducing the occupation of Tiantong business channels; If the fusion terminal cannot initiate a Tiantong call due to insufficient Tiantong channel resources or silence, it can apply to the dispatching platform to initiate a Tiantong call through a call application instruction.
