[0091] Figure 1 is a block diagram of a multi-frequency point coverage wireless trunking communication system of this exemplary embodiment, as Figure 1 shown, the exemplary embodiment of the present disclosure provides a multi-frequency point coverage wireless trunking communication system, including an operation console, radios and mobile terminals; there are n radios; there are n×m mobile terminals; the n radios respectively correspond to n different frequency points; the n radios are connected to the same operation console; each radio corresponds to connect m mobile terminals; the n×m mobile terminals respectively communicate with the same operation console centrally through the n radios.

[0092] It is worth noting that the wireless trunking communication system is widely adopted by departments such as public security, transportation railways, and large enterprises for mobile communication systems for operations such as command, dispatching, and data transmission. As a dedicated wireless communication means for industry applications, the wireless trunking communication system can achieve efficient voice and data communication, as well as reliable command and dispatching. Its system mainly consists of an operation console, radios and mobile terminals. For dispatching hubs with multiple lines or business intersections, there are often scenarios where multiple different frequency points are covered simultaneously. One frequency point represents a separate communication channel, and the system realizes the communication between the operation console and the mobile terminals under that frequency point with the assistance of the radios. The operation console can display the relevant information of the mobile terminals registered under that frequency point in real time and support the establishment of voice or data trunking communication through the interface.

[0093] Figure 1Among them, the interface device supports the access of different communication devices to achieve interconnection and interoperability between devices or systems. The network management server is responsible for the centralized management and control of the entire network, providing functions such as network configuration, performance monitoring, and fault alarm. The network management terminal, as the display interface of the network server, is used to monitor and manage the network status, facilitating network administrators to perform configuration, monitoring, and troubleshooting. The layer-3 switch provides fast forwarding and intelligent routing functions, improving network performance and efficiency, and supporting communication between VLANs. The transmission system is responsible for data transmission and switching to ensure stable and efficient transmission of signals in the communication network. The optical fiber / network, as the communication medium, provides a high-bandwidth and low-loss transmission channel for the wireless trunking communication system.

[0094] In this embodiment, the operation consoles covering multiple frequency points' scheduling areas are centralized to one operation console for management, effectively reducing the construction cost and the difficulty of later maintenance.

[0095] Specifically, the operation console includes a background and a display. As Figure 2 shown, the display is provided with a frequency point switching area, and the frequency point switching area includes multiple target frequency point areas;

[0096] Each target frequency point area includes a frequency point name, a terminal information display area, and a trunking voice communication area;

[0097] The terminal information display area includes the terminal names, terminal locations, terminal types, and groups where m terminals are located;

[0098] The trunking voice communication area includes the group names of N groups, all-call instruction information, and group-call instruction information.

[0099] In this embodiment, the operation console is used for the wireless trunking communication system under multi-frequency point coverage and supports one-key switching of the frequency point operation page. The control information of each frequency point occupies a separate page, and each page can be subdivided into three parts: a frequency point switching area, a terminal information display area, and a trunking voice communication area. The frequency point switching area is at the top of the interface. Operators can switch to the corresponding frequency point operation interface for trunking communication by clicking on the corresponding frequency point information button. On the left side of the frequency point operation interface is the terminal information display area, which is used to display the terminal information registered for this frequency point: terminal name, terminal location, terminal type, and the group where it is located; on the right side is the trunking voice communication area, where operators can initiate all-call communication and select group-call communication for specific groups.

[0100] Voice scheduling, as one of the main functions of the trunking communication system, commonly used methods include group call and all call. In the trunking communication system, multiple groups can be established. The necessary information for a group includes a group number, a group call number, and group members, etc. As Figure 2As shown in the figure, Group 1, Group 2, …, Group N are different groups. The operator can click on the corresponding group number and then click the "Group Call" button to initiate a group call. At this time, the terminal devices that are working within the coverage of this frequency band among the group members will be pulled into the group call, and each member can conduct voice dispatching calls within the group. The full call is a group call with a wider range, and it no longer specifies a specific member range for the group call. When a full call is initiated, all the terminal devices working within the coverage of this frequency band will be pulled into the full call for voice communication.

[0101] This embodiment mainly designs the display logic switching of the console interface, the background management control logic, and the communication protocol between the console and multiple radios simultaneously. The service scenarios include, but are not limited to, the transmission of voice, data, and status information. The main interface types of the wireless trunking communication system include: console information initialization, querying information from the radio by the console, mobile terminal location update, activity detection, call establishment and termination, call status information synchronization, etc.

[0102] Specifically, as Figure 3 shown, the wireless trunking communication system with multi-frequency coverage also includes a communication protocol transceiver module. The background includes a data control module and a voice control module. The data control module includes n frequency band data processing modules, and the voice control module includes n frequency band voice processing modules;

[0103] The radio is connected to the background through the communication protocol transceiver module.

[0104] To achieve the voice and data management of radios with different frequency bands, this embodiment has relatively high requirements for the control logic of the console background. The specific design scheme is as Figure 3 shown:

[0105] The console communicates with the radio program through the communication protocol transceiver module. The communication protocol transceiver module is responsible for protocol transceiver and data encapsulation and parsing. The parsed data is sent to the corresponding module through the internal interface of the console for processing.

[0106] The data control module is responsible for the overall control of data services at different frequencies. The data information is first sent to the data control module to determine the data type and the affiliated radio station. The data control module decides whether the message needs to be transmitted further, who the data service recipient is, which interface to call, whether the interface status needs to be synchronized, etc. according to the overall data service status at this time. The data control module is also responsible for the management of the activity detection between the operation console and each radio station, and the connection status between the storage system and the programs of each radio station. When the connection status between the operation console and radio station n is disconnected, the services of radio station n initiated by the interface or the data processing module of frequency point n will be intercepted, and the disconnection status information will be synchronized to the voice control module at the same time. When the disconnection time of radio station n exceeds 30s (configurable), the data and voice status of frequency point n will be cleared. After the connection is re-established, the operation console will actively request the data information of radio station n to refresh the interface.

[0107] The number of data processing modules / voice processing modules for each frequency point corresponds one-to-one with the number of frequency points covered by the jurisdiction area of the operation console in the operation console configuration file. The data processing module for frequency point n is responsible for the management of the data services of radio station n at frequency point n, including information initialization, querying information from the radio station by the operation console, updating the location of the mobile terminal, activity detection, etc.

[0108] The voice control module is responsible for the overall control of voice services at different frequencies and stores the call status of each frequency point voice processing module. After receiving the voice signaling, the operation console first determines the call status by the voice control module and forwards the voice signaling with the total call status identifier to the corresponding frequency point voice processing module. If the system is in an idle state, the frequency point voice processing module will process the voice signaling normally and establish a call with the radio station. If a certain frequency point of the system is in a call state, the call establishment signaling sent by other radio station programs will be forwarded with the identifier to the corresponding frequency point voice processing module. The corresponding frequency point voice processing module responds to the call establishment information, switches the voice status to the waiting call establishment state, and replies to the radio station with the identifier "The operation console is in a call, please wait". The call initiator can decide whether to wait or end the call. If the call is waiting, after the original call ends, the voice control module sends new status information to the frequency point voice processing module to establish the call. If the call ends during the waiting period, the voice control module forwards the end information to the frequency point voice processing module, and the frequency point voice processing module resumes the idle state. If the system receives two call establishment requests during a call, the second call establishment request will be directly rejected and the identifier "The operation console is busy, the call ends" will be replied.

[0109] The voice processing module for frequency point n is responsible for the management of the voice services of radio station n at frequency point n, including call establishment and end, call status maintenance and jump, etc.

[0110] Such as Figure 4As shown in the figure, an exemplary embodiment of the present disclosure provides a multi-frequency point coverage wireless trunking communication method. Based on the above multi-frequency point coverage wireless trunking communication system, it includes:

[0111] Obtain the interface touch signaling through the background;

[0112] And perform the jump and control of the data and voice states according to the interface touch signaling;

[0113] And control the frequency point switching area to switch to the target frequency point area according to the interface touch signaling.

[0114] In this embodiment, the operator can switch the frequency point operation page with one key for trunking communication, and the system operation is convenient.

[0115] Such as Figure 5 As shown in the figure, an exemplary embodiment of the present disclosure provides a multi-frequency point coverage wireless trunking communication method. Based on the above multi-frequency point coverage wireless trunking communication system, it includes:

[0116] Obtain specific trigger signaling through the background;

[0117] And perform automatic switching of the incoming call interface at a certain frequency point according to the specific trigger signaling.

[0118] Specifically, performing automatic switching of the incoming call interface at a certain frequency point according to the specific trigger signaling includes:

[0119] When a voice call is incoming, the background will receive the specific trigger signaling, the background parses the frequency point information in the specific trigger signaling, and re-frames and sends it to the interface;

[0120] The interface parses the frequency point information and switches the current main page to the corresponding frequency point;

[0121] The background extracts the call number in the specific trigger signaling, and parses the information including the corresponding call type and frames and sends it to the interface;

[0122] The interface pops up a window to prompt a voice call incoming.

[0123] In this embodiment, when being called, the operation console can automatically switch to the operation interface of the called frequency point and pop up a window to prompt the call information, which is user-friendly in design.

[0124] Figure 6 As shown in the figure, an exemplary embodiment of the present disclosure provides a multi-frequency point coverage wireless trunking communication method. Based on the above multi-frequency point coverage wireless trunking communication system, it includes:

[0125] Receive the radio protocol through the communication protocol transceiver module, encapsulate and parse the radio data, and send the parsed radio data to the data control module and the voice control module through the internal interface of the operation console;

[0126] The data control module performs overall control of data services for different frequency points based on the parsed radio data;

[0127] The voice control module performs overall control of voice services for different frequency points based on the parsed radio data, and stores the call status of the voice processing modules at n frequency points.

[0128] Specifically, performing overall control of data services for different frequency points based on the parsed radio data includes:

[0129] The data control module determines the data type and the affiliated radio according to the data information in the parsed radio data;

[0130] The data control module determines whether to forward the data information, the data service recipient, the required interface to be called, and whether to synchronize the interface status according to the current overall service status;

[0131] The data control module performs activity detection management between the operation console and each radio, and stores the connection status between the operation console and the programs of each radio.

[0132] Specifically, performing activity detection management between the operation console and each radio through the data control module and storing the connection status between the operation console and the programs of each radio includes:

[0133] When the connection between the operation console and the nth radio is disconnected, the radio services initiated by the interface or the nth frequency point data processing module are intercepted, and the data control module synchronizes the disconnection status information to the voice control module;

[0134] When the disconnection time of the nth radio exceeds the set time, the data control module clears the data and voice status of the frequency point corresponding to the nth radio;

[0135] After the operation console re - establishes a connection with the nth radio, the data control module actively requests the data information of the nth radio and refreshes the interface.

[0136] Specifically, the voice control module performing overall control of voice services for different frequency points based on the parsed radio data, and storing the call status of the voice processing modules at n frequency points includes:

[0137] After the voice control module receives the voice signaling in the parsed radio data, it determines the current frequency point call status and forwards the voice signaling with the total call status identifier (the voice signaling includes, but is not limited to, call establishment signaling and call termination signaling) to the corresponding frequency point voice processing module; it should be noted that the total call status identifier is used to inform the frequency point voice processing module to which it is forwarded of the overall call status of the current system, facilitating the frequency point voice processing module to judge and reply with a call establishment identifier, an identifier indicating that the console is in a call and please wait, or an identifier indicating that the console is busy and the call has ended. The content included in the total call status identifier includes, but is not limited to: there is no call in each current frequency point voice processing module, there is a call in a non-current frequency point voice processing module, and there is an ongoing voice call at the current frequency point.

[0138] When the frequency point is not in a call state, the frequency point voice processing module processes the voice signaling to establish a call between the console and the radio.

[0139] When a certain frequency point is in a call state, the call establishment signaling in the voice signaling sent by other radio programs (referring to radio programs other than the radio corresponding to the currently called frequency point) is forwarded to the corresponding frequency point voice processing module with the total call status identifier attached.

[0140] The corresponding frequency point voice processing module responds to the call establishment signaling, switches the voice state to the waiting for call establishment state and replies with the first set identifier to the radio that sent the call establishment information; by way of example, the first set identifier is "The console is in a call, please wait".

[0141] When the voice control module obtains a call waiting instruction, after the current call ends, the voice control module forwards the new status information to the frequency point voice processing module.

[0142] The frequency point voice processing module establishes a call between the console and the radio according to the call establishment information.

[0143] When the voice control module obtains an end call instruction, the voice control module forwards the end information to the frequency point voice processing module.

[0144] The frequency point voice processing module resumes the idle state.

[0145] When a certain frequency point is in a call state and receives multiple call establishment requests, the second and subsequent call establishment requests are rejected, and the second set identifier is replied to the radio that sent the call establishment request; by way of example, the second set identifier is "The console is busy, call ended".

[0146] On the basis of not affecting the original functions and being compatible with the console to identify and distinguish data / calls of different frequency point radios, the specific content of the communication protocol design in this embodiment is as follows:

[0147] During the software deployment period before the on - line operation on the operation console, configure the radio frequencies and corresponding IPs under the jurisdiction of this operation console. After the program starts automatically, the operation console will store the corresponding relationship between the radio frequencies and radio IPs locally;

[0148] Operation console information initialization / Operation console queries information from the radio: The operation console information initialization is similar to the protocol content of the operation console querying information from the radio. The former is used for batch data synchronization after one of the operation console or the radio starts the program, and the latter is used for updating one or some data during the process of the program. Such protocols include information such as service type, frequency information, terminal name, terminal location, terminal type, group information, call range of each group, equipment performance, etc. When the operation console queries, it directly sends a request message to the radio corresponding to the IP according to the corresponding relationship between the radio frequency and radio IP stored locally. When the radio returns a receipt, an information block of the sending radio IP is added to the data field of the frame format so that the operation console can locate the information of the sender of the data frame.

[0149] Mobile terminal location update: The location information of mobile terminals for each frequency is managed separately. It includes service type, frequency information, terminal name, terminal location, terminal type, the group it belongs to, radio IP, etc. When the terminal information changes or the frequency on the interface is switched, the two parties interact once.

[0150] Activity detection: It includes service type, message sequence number, message sequence number of the message to be responded, etc. Activity detection is actively sent by the operation console at regular intervals in a loop. If no receipt is received within three sending intervals, the connection is considered to be disconnected. During the disconnection period, the operation console still sends activity detection information in a loop. When it receives the activity detection receipt from the radio and determines that the connection is restored, the internal modules of the operation console will resume relevant service functions in sequence.

[0151] Call establishment and termination, call status information synchronization: In the normal state, the formats of call establishment and termination, and call status information synchronization use standard SIP signaling. However, in order to meet the requirements of voice control for multiple radios, the meanings of some SIP response codes are re - defined. For example, 180 Ringing is used to indicate the receipt of call establishment when there is already a call on the operation console, and its meaning is "The operation console is in a call, please wait". 486 Busy Here is used as the rejection receipt for call establishment when there is already a call in the 180 Ringing state on the operation console, and its meaning is "The operation console is busy, call ended".

[0152] As Figure 7 shown, the exemplary embodiment of the present disclosure provides a wireless trunking communication method with multi - frequency coverage. Based on the above - mentioned wireless trunking communication system with multi - frequency coverage, it includes the operation console power - on initialization step:

[0153] When the console is powered on, it actively obtains the frequency point information covered by this dispatching section from the database or configuration file;

[0154] Read the terminal information and group call group information corresponding to the frequency points in the database in sequence;

[0155] Parse the terminal information and group call group information read from the database;

[0156] Draw the interface according to the parsed information.

[0157] As Figure 8 shown, an exemplary embodiment of the present disclosure provides a wireless trunking communication method with multi-frequency point coverage. Based on the above wireless trunking communication system with multi-frequency point coverage, it includes a terminal information synchronization step:

[0158] When the terminal registration information changes, the radio will send a terminal registration information synchronization signaling to the console;

[0159] After receiving the terminal registration information, the console parses the corresponding frequency point information;

[0160] The console reads the terminal information in the database according to the frequency point information and compares it with the terminal information stored in the console;

[0161] If the comparison return value is true, the console will overwrite the original stored terminal information and parse the necessary fields of the terminal information to form frame data and send it to the interface to update the terminal information;

[0162] If the comparison return value is false, the console abandons this information update.

[0163] In this embodiment, the console reads the terminal information in the database according to the frequency point information and compares it with the terminal information stored in the console; if the comparison return value is true, it indicates that at least one of the fields of the terminal name, terminal location, terminal type, and group where the terminal is located read by the interface in the terminal information has changed. The console will overwrite the original stored terminal information and parse the necessary fields of the terminal information to form frame data and send it to the interface to update the terminal information. If the comparison return value is false, it indicates that the fields have not changed, and this information update is abandoned.

[0164] As Figure 9 shown, an exemplary embodiment of the present disclosure provides a wireless trunking communication method with multi-frequency point coverage. Based on the above wireless trunking communication system with multi-frequency point coverage, it includes a group call initiation step:

[0165] The operator first selects a group information in the cluster voice communication area, such as "Group 1". Then click the group call button to initiate a group call;

[0166] The interface sends the frame data with the frequency point and call number to the background;

[0167] The background parses the frequency point information in the frame data to determine the radio address information of the called party;

[0168] Then parse the call number in the frame data to determine the call type;

[0169] Finally, the console encapsulates the SIP signaling and sends it to the radio, and a voice channel is established between the console and the radio.

[0170] As Figure 10 shown, an exemplary embodiment of the present disclosure provides a multi-frequency point coverage wireless trunking communication method. Based on the above multi-frequency point coverage wireless trunking communication system, it includes a full call initiation step:

[0171] The operator clicks the full call button in the trunking voice communication area to initiate a full call;

[0172] The interface sends the frame data with the frequency point and call number to the background;

[0173] The background first parses the frequency point information in the frame data to determine the radio address information of the called party;

[0174] Then parse the call number in the frame data to determine the call type;

[0175] Finally, the console encapsulates the SIP signaling and sends it to the radio, and a voice channel is established between the radio and the console.

[0176] The present disclosure realizes the communication requirements of different frequency point radios through the one-key switching of the interface form, integrates the functions of multiple consoles into one console to complete, realizes the centralized control of radio communication and the efficient utilization of the space in the dispatching hall of the dispatching hub station.
