It has been widely used in a large number of special communication fields such as aviation communication, transportation, and public safety. Some dispatching hubs have multi-line fusion scenarios, and it is necessary to complete the communication of multiple radio stations with different frequencies in one venue. In the traditional wireless cluster communication system with multi-frequency coverage, in order to achieve normal communication in multi-frequency scenarios, the communication needs of radio stations with different frequencies are often achieved by increasing the number of operating desks, that is, placing multiple operating desks in the dispatching area, which are responsible for cluster communications at different frequencies.

[0029] Figure 1 is a block diagram of a wireless cluster communication system with multi-frequency coverage according to the exemplary embodiment of the present invention. Figure 1As shown, an exemplary embodiment of the present disclosure provides a wireless cluster communication system with multi-frequency coverage, including an operation station, a radio station and a mobile terminal; n radio stations are set; n×m mobile terminals are set; the n radio stations correspond to n different frequency points respectively; the n radio stations are connected to the same operation station; each radio station is connected to m mobile terminals; the n×m mobile terminals communicate with the same operation station through the n radio stations respectively.

[0030] It is worth mentioning that the wireless cluster communication system is a mobile communication system widely used by public security, transportation railways, large enterprises and other departments for command, dispatch, data transmission and other services. As a dedicated wireless communication means for industry applications, the wireless cluster communication system can achieve efficient voice and data communication, as well as reliable command and dispatch. The system is mainly composed of an operation console, a radio and a mobile terminal. For a dispatch hub with multiple lines or business intersections, there are often scenarios where multiple different frequency points are covered at the same time. A frequency point represents a separate communication channel. The system realizes communication between the operation console and the mobile terminal at the frequency point with the assistance of the radio point according to the assigned frequency point. The operation console can display the relevant information of the mobile terminal registered at the frequency point in real time, and supports the establishment of voice or data cluster communication through the interface.

[0031] Figure 1 In the network, the interface device supports the access of different communication devices to achieve interconnection between devices or systems. The network management server is responsible for the centralized management and control of the entire network, and provides functions such as network configuration, performance monitoring, and fault alarm. The network management terminal serves as the display interface of the network server, which is used to monitor and manage the network status, making it convenient for network administrators to configure, monitor, and troubleshoot. The three-layer switch provides fast forwarding and intelligent routing functions, improves network performance and efficiency, and supports inter-VLAN communication. The transmission system is responsible for the transmission and exchange of data to ensure the stable and efficient transmission of signals in the communication network. As a communication medium, optical fiber / network provides a high-bandwidth, low-loss transmission channel for the wireless cluster communication system.

[0032] This embodiment centralizes the management of operation consoles covering multiple frequency dispatching areas into one operation console, effectively reducing construction costs and subsequent maintenance difficulties.

[0033] Specifically, the operation console includes a background and a display, such as Figure 2 As shown, the display is provided with a frequency switching area, and the frequency switching area includes a plurality of target frequency areas; Each target frequency area includes a frequency name, a terminal information display area, and a trunking voice communication area; The terminal information display area includes the terminal name, terminal location, terminal type and terminal group of the m terminals; The trunking voice communication area includes group names, all-call instruction information and group-call instruction information of N groups.

[0034] In this embodiment, the operating console is used for a wireless cluster communication system under multi-frequency coverage, and supports one-click frequency operation page switching. The control information of each frequency occupies a separate page, and each page can be subdivided into three parts: frequency switching area, terminal information display area, and cluster voice communication area. The top of the interface is the frequency switching area, and the operator can switch to the corresponding frequency operation interface for cluster communication by clicking the corresponding frequency information button. In the frequency operation interface, the left side is the terminal information display area, which is used to display the terminal information registered for the frequency: terminal name, terminal location, terminal type and group; the right side is the cluster voice communication area, and the operator can initiate a full call communication and select a group call communication for a specific group.

[0035] As one of the main functions of the trunking communication system, voice dispatch is commonly used in two ways: group call and general call. In the trunking communication system, multiple groups can be established. The necessary information of the group includes the group number, group call number and group members. Figure 2 As shown in the figure, Group 1, Group 2, ..., Group N are different groups. The operator can select the corresponding group number and then click the "Group Call" button to initiate a group call. At this time, the terminal devices of the group members working within the coverage of the frequency point will be pulled into the group call, and each member can make a voice dispatch call in the group. All call is a wider range of group calls, which no longer specifies a specific member range for group calls. When an all call is initiated, all terminal devices working within the coverage of the frequency point will be pulled into the all call for voice communication.

[0036] This embodiment mainly designs the console interface switching display logic, background management control logic, and the communication protocol between the console and multiple radio stations at the same time. The business scenarios include but are not limited to voice, data, and status information transmission. The main interface types of the wireless trunking communication system include: console information initialization, console query information from radio stations, mobile terminal location update, activity detection, call establishment and termination, call status information synchronization, etc.

[0037] Specifically, Figure 3 As shown, the wireless cluster communication system with multi-frequency coverage also includes a communication protocol transceiver module, and the background includes a data control module and a voice control module. The data control module includes n frequency data processing modules, and the voice control module includes n frequency voice processing modules; The radio station is connected with the background via a communication protocol transceiver module.

[0038] In order to realize the voice and data management of radio stations with different frequencies, this embodiment has high requirements on the control logic of the operation console background. The specific design scheme is as follows: Figure 3 As shown: The console communicates with the radio program through the communication protocol transceiver module. The communication protocol transceiver module is responsible for protocol transmission and reception and data encapsulation and analysis. The parsed data is sent to the corresponding module for processing through the internal interface of the console.

[0039] 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 radio station to which it belongs. The data control module determines whether the message needs to be transmitted in the next step, who the data service recipient is, which interface to call, whether the interface status needs to be synchronized, and other subsequent processes based on the overall data service status at this time. The data control module is also responsible for the management of activity detection between the console and each radio station, and the connection status between the storage system and each radio program. When the connection between the console and radio station n is disconnected, the service of radio station n initiated by the interface or frequency point n data processing module will be intercepted, and the disconnection status information will be synchronized to the voice control module. 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 console will actively request the data information of radio station n and refresh the interface.

[0040] The number of frequency data processing modules / frequency voice processing modules corresponds to the number of frequencies covered by the operator's jurisdiction in the operator's configuration file. The frequency n data processing module is responsible for the management of frequency n radio data services, including information initialization, the operator's query of information to the radio, mobile terminal location updates, activity detection, etc.

[0041] The voice control module is responsible for the overall control of voice services at different frequencies and stores the call status of the voice processing modules at each frequency. After the console receives the voice signaling, the voice control module first determines the call status and forwards the voice signaling with the total call status identifier to the corresponding frequency voice processing module. If the system is in a non-call state, the frequency voice processing module will process the voice signaling normally and establish a call with the radio station. If a certain frequency of the system is in a call state, the call establishment signaling sent by other radio programs will be forwarded to the corresponding frequency voice processing module with the identifier. The corresponding frequency voice processing module responds to the call establishment information and switches the voice state to the waiting call establishment state and replies to the radio station with the "operator is in a call, please wait" identifier. The call initiator can decide to wait or end the call. If the call is waited, after the original call ends, the voice control module sends new status information to the frequency voice processing module and the call is established. If the call ends during the waiting period, the voice control module forwards the end information to the frequency voice processing module, and the frequency voice processing module returns to 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 "operation console is busy, call ended" mark will be replied.

[0042] The frequency n voice processing module is responsible for the management of the frequency n radio station voice service, including call establishment and termination, call status maintenance and jump, etc.

[0043] like Figure 4 As shown, an exemplary embodiment of the present disclosure provides a wireless cluster communication method with multi-frequency coverage, based on the wireless cluster communication system with multi-frequency coverage, including: Get the interface touch signaling through the background; And according to the interface touch signaling, the data and voice status are jumped and controlled; And according to the interface touch signaling, the frequency switching area is controlled to switch to the target frequency area.

[0044] In this embodiment, the operator can switch the frequency operation page to perform trunking communication with one click, and the system operation is convenient.

[0045] like Figure 5 As shown, an exemplary embodiment of the present disclosure provides a wireless cluster communication method with multi-frequency coverage, based on the wireless cluster communication system with multi-frequency coverage, including: Obtain specific trigger signaling through the background; And according to the specific trigger signal, the power-down interface automatically switches at a certain frequency.

[0046] Specifically, according to a specific trigger signaling, automatic switching of the power-down interface at a certain frequency includes: When a voice call comes in, the background will receive a specific trigger signal, analyze the frequency information in the specific trigger signal, and reframe it and send it to the interface; The interface analyzes the frequency information and switches the current main page to the corresponding frequency; The background extracts the call number in the specific trigger signaling, parses the information including the corresponding call type, and frames it to send to the interface; A pop-up window will pop up on the interface to prompt an incoming voice call.

[0047] In this embodiment, when a call is received, the operation console can automatically switch to the operation interface of the called frequency and pop up a window to prompt the call information, which is user-friendly.

[0048] Figure 6 As shown, an exemplary embodiment of the present disclosure provides a wireless cluster communication method with multi-frequency coverage, based on the wireless cluster communication system with multi-frequency coverage, including: Receive the radio protocol and encapsulate and parse the radio data through the communication protocol transceiver module, and send the parsed radio data to the data control module and the voice control module through the internal interface of the console; The data control module performs overall control of data services at different frequencies based on the parsed radio station data; The voice control module performs overall control of voice services at different frequencies based on the parsed radio station data, and stores the call status of n frequency voice processing modules.

[0049] Specifically, the overall control of data services at different frequencies based on the parsed radio station data includes: The data control module determines the data type and the radio station to which it belongs based on the data information in the parsed radio station data; The data control module determines whether to forward data information, the data service recipient, the interface to be called, and whether to synchronize the interface status based on the current overall business status; The data control module is used to detect and manage the activity of the operating console and each radio station, and store the connection status between the operating console and each radio station program.

[0050] Specifically, the activity detection management of the operation console and each radio station is performed through the data control module, and the connection status between the operation console and each radio station program is stored, including: When the connection between the console and the nth radio station is disconnected, the radio service initiated by the interface or the nth frequency point data processing module is intercepted, and the data control module synchronizes the disconnection status information to the voice control module; When the disconnection time of the nth radio station exceeds the set time, the data control module clears the data and voice status of the corresponding frequency of the nth radio station; When the console re-establishes the connection with the nth radio station, the data control module actively requests the data information of the nth radio station and refreshes the interface.

[0051] Specifically, the voice control module performs overall control of voice services at different frequencies according to the parsed radio station data, and stores the call status of the n frequency voice processing modules, including: After receiving the voice signaling in the parsed radio data, the voice control module determines the current frequency call status and forwards the voice signaling (voice signaling including but not limited to call establishment signaling and call end signaling) with the total call status identifier to the corresponding frequency voice processing module; it is worth noting that the total call status identifier is used to inform the frequency voice processing module forwarded to the overall call status of the current system, so that the frequency voice processing module can judge the reply call establishment identifier, the console is in a call please wait identifier or the console is busy call end identifier. The total call status identifier includes but is not limited to: there is no call in the current frequency voice processing module, there is a call that is not in the current frequency voice processing module, and there is a voice call in progress at the current frequency.

[0052] When the frequency point is not in the call state, the frequency point voice processing module processes the voice signaling to establish a call between the operation console and the radio station; When a certain frequency 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 frequency currently in the call state) is forwarded to the corresponding frequency voice processing module with the total call state identifier; The corresponding frequency point voice processing module responds to the call establishment signaling, switches the voice state to the waiting call establishment state and replies the first setting identifier of the radio station to the radio station that sent the call establishment information; illustratively, the first setting identifier is "the operation console is on the phone, please wait".

[0053] When the voice control module obtains the call waiting instruction, after the current call ends, the voice control module forwards the new status information to the frequency point voice processing module; The frequency point voice processing module establishes a call between the operation console and the radio station according to the call establishment information; When the voice control module obtains the call end instruction, the voice control module forwards the end information to the frequency point voice processing module; The frequency point voice processing module returns to idle state; When a frequency point is in a call state and receives multiple call establishment requests, the second and subsequent call establishment requests are rejected, and a second setting identifier is replied to the station that issued the call establishment request. For example, the second setting identifier is "the operation station is busy, the call is ended".

[0054] On the basis of not affecting the original functions and being compatible with the operation console to identify and distinguish data / calls of radio stations with different frequencies, the specific contents of the communication protocol design of this embodiment are as follows: During the software deployment period before the console goes online, configure the radio frequencies and corresponding IPs under the control of the console. After the program is started, the console will store the correspondence between radio frequencies and radio IPs locally; Initialization of console information / query of information from the console to the radio station: The contents of the protocols for initialization of console information and query of information from the console to the radio station are similar. The former is used for batch data synchronization after a program is started on the console or the radio station, and the latter is used to update one or some data during the program. This type of protocol includes information such as service type, frequency information, terminal name, terminal location, terminal type, group information, call range of each group, and equipment performance. When the console queries, the console directly sends a request message to the radio station with the corresponding IP based on the correspondence between the radio frequency and the radio IP stored locally. When the radio station replies, the sending radio IP information block is added to the data field of the frame format so that the console can locate the sender information of the data frame.

[0055] Mobile terminal location update: The mobile terminal location information of each frequency point is managed separately. Including service type, frequency point information, terminal name, terminal location, terminal type, group, radio station IP, etc. When the terminal information changes or the interface frequency point switches, the two sides interact once.

[0056] Activity detection: including service type, message sequence number, and message sequence number being responded to. Activity detection is actively sent by the console in a regular cycle. If no receipt is received within three sending intervals, the connection is considered disconnected. During the disconnection period, the console still sends activity detection information in a cycle. When the activity detection receipt from the radio station is received and the connection is judged to be restored, the internal modules of the console will restore the relevant service functions in sequence.

[0057] Call establishment and termination, call status information synchronization: Under normal conditions, call establishment and termination, and call status information synchronization formats use standard SIP signaling. However, in order to meet the requirements of voice control of multiple radio stations, the meanings of some SIP response codes have been redefined. For example, 180 Ringing is used to indicate a receipt for call establishment when the console is already on a call, which means "the console is on a call, please wait." 486 Busy Here is used for a rejection receipt for call establishment when the console already has a call in the 180Ringing state, which means "the console is busy, the call is over."

[0058] like Figure 7 As shown, an exemplary embodiment of the present disclosure provides a wireless cluster communication method with multi-frequency coverage, based on the wireless cluster communication system with multi-frequency coverage, including the operation console startup initialization step: When the console is turned on, it will actively obtain the frequency information covered by this dispatching section from the database or configuration file; Read the terminal information and group call group information of the corresponding frequency points in the database in sequence; Parse the terminal information and group call group information read from the database; Draw the interface based on the parsed information.

[0059] like Figure 8 As shown, an exemplary embodiment of the present disclosure provides a wireless cluster communication method with multi-frequency coverage, based on the wireless cluster communication system with multi-frequency coverage, including a terminal information synchronization step: When the terminal registration information changes, the radio station will send the terminal registration information synchronization signaling to the operation console; After receiving the terminal registration information, the console parses the corresponding frequency information; The operation console reads the terminal information from the database according to the frequency information and compares it with the terminal information stored in the operation console; If the comparison returns true, the console will overwrite the original stored terminal information, 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, the console abandons this information update.

[0060] In this embodiment, the console reads the terminal information in the database according to the frequency 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 terminal name, terminal location, terminal type and group read by the interface in the terminal information has changed, and 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, indicating that the field has not changed, the information update is abandoned.
