[0001] This invention relates to the field of communication technology, specifically providing a distributed converged communication system and its communication method, communication device, and electronic device. Background Technology

[0002] In emergency communications for disasters such as earthquakes and forest fires, communication is often interrupted due to damage to basic communication infrastructure or because the area itself is a coverage blind spot. To ensure communication reliability in emergency situations and to obtain as much information as possible from the disaster site, multiple communication methods are usually deployed simultaneously, such as shortwave, VHF, IP telephony, video conferencing, and video backhaul, and satellite communication is used to achieve wide-area transmission between the disaster site and the command center. However, not every person or node has full access to all communication methods, and currently, these various communication methods exist as independent systems, operating according to their own protocols and communication processes. These systems cannot interconnect, causing inconvenience in information exchange and personnel communication, and reducing communication efficiency.

[0003] Accordingly, there is a need in this field for a new distributed converged communication system solution to address the above problems. Summary of the Invention

[0004] To overcome the above-mentioned defects, this invention is proposed to provide a distributed converged communication system and its communication method, communication device and electronic equipment that solve or at least partially solve the technical problems of the inability of various systems to interconnect, resulting in inconvenience in information interaction and personnel communication and low communication efficiency.

[0006] In one technical solution of the above-mentioned distributed converged communication system, the interface module adopts one or more physical interfaces selected from DB9, RS232, RS485, RJ45 and RJ11.

[0007] In one technical solution of the above-mentioned distributed converged communication system, the status management module periodically monitors the status of each of the target communication systems, and stops monitoring the status of the unresponsive target communication systems after failing to receive a response from each of the target communication systems within a preset number of times.

[0008] In one technical solution of the aforementioned distributed converged communication system, the protocol conversion module uses the SIP protocol as an intermediate adaptation protocol to convert the protocols and signaling of all the target communication systems to correspondence with the SIP protocol and signaling, including the mutual conversion between PSIP, SS7, RTSP and SIP protocols. After conversion, the interoperability of control signaling between the various target communication systems can be achieved.

[0009] In a second aspect, the present invention provides a communication method for a distributed converged communication system, applied to the distributed converged communication system described in the above technical solution. The method includes: responding to a call instruction sent by a first target communication terminal corresponding to a target communication system communicatively connected to the distributed converged communication system; controlling a multi-mode communication module to acquire call number information in the call instruction and transmit it to a number management module; controlling the number management module to analyze the number type of the call number and the communication mode for establishing converged communication, and sending the analysis result to the multi-mode communication module; the multi-mode communication module making a call to a second target communication terminal corresponding to the communication mode for establishing converged communication based on the analysis result, so as to establish communication between the first target communication terminal and the second target communication terminal.

[0010] In one technical solution of the communication method of the aforementioned distributed converged communication system, the step of "controlling the number management module to analyze the number type of the calling number and establish the communication mode of converged communication" specifically includes: determining whether the calling number is composed of a distributed node coding segment, a communication packet coding segment, and a terminal coding segment in sequence; if so, determining whether the distributed node number segment is distributed node local communication; otherwise, not executing the step of "sending the analysis result to the multi-mode communication module" and stopping the establishment of converged communication; if it is distributed node local communication, the communication mode of establishing converged communication is intra-node communication; if it is not distributed node local communication, the communication mode of establishing converged communication is wide-area communication.

[0011] In one technical solution of the communication method of the aforementioned distributed converged communication system, the step of "the multi-mode communication module calling the second target communication terminal corresponding to the communication mode for establishing converged communication based on the analysis result" specifically includes: if the communication mode for establishing converged communication is wide-area communication, then calling the corresponding second target communication terminal via satellite communication; if the communication mode for establishing converged communication is intra-node communication, then controlling the status management module to query the status of the system corresponding to the second target communication terminal corresponding to the intra-node communication; if the status of the system corresponding to the second target communication terminal is normal, then controlling the multi-mode communication module to call the second target communication terminal through internal communication port information; if the status of the system corresponding to the second target communication terminal is abnormal, then stopping the establishment of converged communication.

[0012] In one technical solution of the communication method of the above-mentioned distributed converged communication system, before the step of "controlling the multi-mode communication module to call the second target communication terminal through internal communication port information", the method further includes: controlling the protocol conversion module to convert the protocol and signaling of the system corresponding to the first target communication terminal into a protocol and signaling that the system corresponding to the first target communication terminal can receive.

[0024] Some embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

A module may include hardware circuitry, various suitable sensors, communication ports, and memory, and may also include software components, such as program code, or a combination of software and hardware.

[0026] Example 1

[0027] See appendix Figure 1 , Figure 1 This is a schematic diagram of a distributed converged communication system provided according to an embodiment of the present invention.

[0028] like Figure 1 As shown, the distributed converged communication system includes an interface module, a status management module, a number management module, a multi-mode communication module, and a protocol conversion module. The interface module is used to connect different target communication systems, and each communication interface in the interface module is used to transmit data with the target communication systems. The status management module is used to monitor the status of each target communication system. The number management module is used to record the number sets of each terminal of each target communication system according to a preset number format. The multi-mode communication module is used to establish converged communication. The protocol conversion module is used to convert the protocols and signaling of each target communication system so that the control signaling between the target communication systems can communicate with each other.

[0029] It should be noted that the converged communication system refers to the system in which multiple target communication systems at the disaster site and the command center need to interact during emergency communication, and the existing multiple target communication systems at the disaster site and the command center are respectively connected to the converged communication system of this invention to form a converged communication system.

[0030] Furthermore, the distributed converged communication system of the present invention can connect to one or more communication systems such as shortwave, ultra-shortwave, IP telephony, landline telephone, mobile phone, video conferencing, and video backhaul. The embodiments of the present invention do not impose specific limitations.

[0031] Furthermore, the interface module adopts one or more physical interfaces selected from DB9, RS232, RS485, RJ45, and RJ11 to connect to one or more target communication systems, including shortwave, VHF, IP telephony, landline, mobile phone, video conferencing, video backhaul, and satellite communication. This embodiment of the invention does not impose specific limitations.

[0032] Furthermore, the preset number format can be composed of a distributed node coding segment, a communication packet coding segment, and a terminal coding segment. The distributed node coding segment represents the corresponding distributed node; the communication packet coding segment represents different communication packets under that distributed node; and the terminal coding segment represents the terminal under the corresponding communication packet. For example, 01020000 represents all terminals under distributed node 01 and communication packet 02; 01020001 represents the first type of terminal under distributed node 01 and communication packet 02. This embodiment of the invention does not impose specific limitations.

[0033] Furthermore, the status management module can periodically monitor the status of the communication system, and stop monitoring the status of the unresponsive communication system after failing to receive a response from any system in the target communication system within a preset number of times.

[0034] It should be noted that periodic monitoring can be implemented using a timer. The timer period can be set to any time within the range of 10 seconds to 300 seconds, with an adjustment step of 10 seconds. The timer cycles continuously, triggering an inquiry message to the corresponding communication system at each set timer period. Simultaneously, the number of inquiry messages is preset, which can be any number of times, such as 3, 4, or 5. If the preset number of inquiries is exceeded consecutively without a response, the communication system without a response is considered offline, and monitoring of the status of the unresponsive communication system ends. This embodiment of the invention does not impose specific limitations.

[0035] Furthermore, the protocol conversion module uses the standard SIP protocol as an intermediate adaptation protocol to convert the protocols and signaling of all connected communication systems to SIP protocol and signaling correspondence, including mutual conversion between PSIP, SS7, RTSP and SIP protocols. After conversion, the interoperability of control signaling between various communication systems can be achieved.

[0036] In implementing the technical solution of this invention, the distributed converged communication system includes an interface module, a status management module, a number management module, a multi-mode communication module, and a protocol conversion module. The interface module connects different target communication systems, and each communication interface within the interface module enables data transmission with the target communication system, allowing communication with different systems and effectively improving the flexibility of interaction between different systems, thus increasing the convenience of communication between target communication systems. The status management module monitors the status of each target communication system, enabling timely detection of the status of the access system and improving the accuracy and timeliness of communication between target communication systems. The number management module records each number according to a preset number format. The set of numbers for each terminal in the target communication system allows for analysis of the number format to accurately determine whether a number can establish a communication connection with the corresponding terminal in the set, thus improving the accuracy of communication between different target communication systems corresponding to a number. The multi-mode communication module is used to establish converged communication, while the protocol conversion module converts the protocols and signaling of each target communication system to enable intercommunication of control signaling, improving the ease of connection to each target communication system. Furthermore, the protocol conversion module transforms the protocols of different target communication systems into mutually communicable protocols, greatly increasing the scalability of the distributed converged communication system.

[0037] Example 2

[0038] Figure 2 This is a flowchart illustrating the main steps of a communication method in a distributed converged communication system according to an embodiment of the present invention. Figure 2 As shown, the communication method of the distributed converged communication system in this embodiment of the invention is applied to the distributed converged communication system of the above embodiment. The communication method of the distributed converged communication system mainly includes the following steps S101-S103.

[0039] Step S101: In response to the call command sent by the first target communication terminal corresponding to the target communication system connected to the distributed converged communication system, control the multi-mode communication module to obtain the call number information in the call command and transmit it to the number management module.

[0040] Step S102: The control number management module analyzes the number type of the calling number and establishes the communication mode of the converged communication, and sends the analysis results to the multi-mode communication module.

[0041] Step S103: The multi-mode communication module makes a call to the second target communication terminal corresponding to the communication mode for establishing converged communication based on the analysis results, so as to establish communication between the first target communication terminal and the second target communication terminal.

[0042] In this embodiment, the target communication system can be one or more of the following: shortwave, VHF, IP phone, landline phone, mobile phone, video conferencing, video backhaul, and satellite communication. This embodiment of the invention does not impose specific limitations.

[0043] Furthermore, in one possible implementation, the number management module can pre-define number rules to divide and map all access target communication systems into a unified number set. When a target communication system needs to make a communication call, it can compare the number with the number in the unified number set according to the number rules. If the number matches the number rules, the communication mode for establishing converged communication is determined, and the analysis result is sent to the multi-mode communication module. Otherwise, the establishment of converged communication is stopped.

[0044] It should be noted that the number set includes the original numbers of each terminal in each communication system, communication groups based on actual communication needs, and communication groups that divide the terminals of different communication systems into groups for use by a specific group or personnel. A unified number is planned according to the communication group, and the unified number corresponds to a group of communication terminals within that communication group.

[0045] The numbering rules consist of a distributed node coding segment, a communication packet coding segment, and a terminal coding segment. The distributed node coding segment represents the corresponding distributed node; the communication packet coding segment represents the different communication packets under that distributed node; and the terminal coding segment represents the terminal under the corresponding communication packet. For example, 01020000 represents all terminals under distributed node 01 and communication packet 02; 01020001 represents the first type of terminal under distributed node 01 and communication packet 02.

[0046] Furthermore, in one possible implementation, it can be determined whether the call number is composed of a distributed node code segment, a communication packet code segment, and a terminal code segment in sequence. If the call number is composed of a distributed node code segment, a communication packet code segment, and a terminal code segment in sequence, it is determined whether the distributed node number segment is local communication of the distributed node. If so, the communication mode for establishing converged communication is intra-node communication; if not, the communication mode for establishing converged communication is wide-area communication. If the call number is not composed of a distributed node code segment, a communication packet code segment, and a terminal code segment in sequence, the step of "sending the analysis results to the multi-mode communication module" is not executed, and the establishment of converged communication is stopped.

[0047] Furthermore, if the communication method for establishing converged communication is wide-area communication, then a call is made to the corresponding second target communication terminal via satellite communication; if the communication method for establishing converged communication is intra-node communication, then the control status management module queries the status of the system corresponding to the second target communication terminal for intra-node communication; if the status is normal, then the control multi-mode communication module makes a call to the second target communication terminal through internal communication port information; if the status is abnormal, then the establishment of converged communication is stopped.

[0048] Furthermore, before the multi-mode communication module calls the second target communication terminal through its internal communication port information, the protocol conversion module can also be controlled to convert the protocol and signaling of the system corresponding to the first target communication terminal into a protocol and signaling that the system corresponding to the first target communication terminal can receive.

[0049] Based on the above steps S101-S103, in response to the call command sent by the first target communication terminal corresponding to the target communication system connected to the distributed converged communication system, the multi-mode communication module is controlled to obtain the call number information in the call command and transmit it to the number management module. Then, the number management module is controlled to analyze the number type of the call number and establish the converged communication communication method, and send the analysis result to the multi-mode communication module. Finally, the multi-mode communication module calls the second target communication terminal corresponding to the converged communication communication method according to the analysis result, so as to establish communication between the first target communication terminal and the second communication terminal.

[0050] Using the above method, multiple communication systems can be accessed through standard communication interfaces without modifying the existing communication systems. At the same time, a method for calling using the original system numbers is designed in the number management system, so that users can use converged communication while still maintaining the communication methods within the original system, thus ensuring compatibility with the original communication systems.

[0051] The status management module can verify the registration information of the accessed communication systems. Unauthorized access systems will not be able to participate in the converged communication, thus avoiding unpredictable harm to the converged communication process caused by unauthorized access and providing a certain level of security for the converged communication.

[0052] The number management module creates a unified number system by establishing number rules. Users no longer need to distinguish between specific communication systems and terminals. When the accessed communication system and terminal change, only the number mapping needs to be modified. Users do not need to pay attention to the details of the changes, which makes it convenient for users.

[0053] The number management module and the multi-mode communication module jointly distinguish between communication within the original system, local converged communication, and wide-area converged communication, dividing the communication scope accordingly. The protocol conversion module uses the standard SIP protocol as an intermediate adaptation protocol to facilitate communication in IP networks. At the same time, it establishes basic communication process rules and standardizes basic communication methods, making the system standardized.

[0054] When a new communication system or terminal is connected in the number management module, only the unified number mapping table needs to be updated. Meanwhile, the protocol conversion module uses the SIP protocol as an intermediate adaptation protocol. When a new communication system is connected, only the mapping conversion between the corresponding communication system's communication protocol and the SIP protocol needs to be added, which has scalability.

[0055] It should be noted that although the steps in the above embodiments are described in a specific order, those skilled in the art will understand that in order to achieve the effects of the present invention, different steps do not necessarily have to be executed in such an order. They can be executed simultaneously (in parallel) or in other orders, and these variations are all within the scope of protection of the present invention.

[0056] Furthermore, the present invention also provides a communication device for a distributed converged communication system.

[0057] See appendix Figure 3 , Figure 3 This is a main structural block diagram of a communication device in a distributed converged communication system according to an embodiment of the present invention. Figure 3 As shown, the communication device of the distributed converged communication system in this embodiment of the invention mainly includes an acquisition module 11, an analysis module 12, and a communication establishment module 13. In some embodiments, one or more of the acquisition module 11, analysis module 12, and communication establishment module 13 can be combined into a single module. In some embodiments, the acquisition module 11 can be configured to respond to a call instruction sent by a first target communication terminal corresponding to a target communication system connected to the distributed converged communication system, control the multi-mode communication module to acquire the call number information in the call instruction, and transmit it to the number management module. The analysis module 12 can be configured to control the number management module to analyze the number type of the call number and the communication method for establishing converged communication, and send the analysis results to the multi-mode communication module. The communication establishment module 13 can be configured to allow the multi-mode communication module to call a second target communication terminal corresponding to the communication method for establishing converged communication based on the analysis results, so as to establish communication between the first target communication terminal and the second communication terminal. In one embodiment, a description of the specific functions can be found in steps S101 to S103.
