[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] It should be noted that, in the description of the present invention, the term "include" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] The terms "first", "second", etc. in the present invention are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present invention can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more.

[0034] Combine the following Figure 1-Figure 10 The invention describes a shortwave communication network access method, device, system, equipment and storage medium.

[0035] Shortwave communication, also known as high frequency (HF) communication, is the use of electromagnetic waves with a frequency range of 1.6MHz~30MHz for wireless communication. As an important means of communication in the field of communications, shortwave communication has the advantages of long communication distance, strong anti-destruction, low operating cost, and easy equipment installation. It has long been widely used in message transmission, weather broadcasting, commercial communication, navigation and aviation, military command, flood prevention and disaster relief, etc. In recent years, with the development and maturity of shortwave communication equipment, shortwave communication has developed in the direction of networking and systematization. Interconnecting shortwave communication equipment through shortwave networking technology and improving the coverage and guarantee capability of shortwave communication through system integration has become the current development direction of shortwave communication systems.

[0036] Modern shortwave networking communication systems are generally composed of a fixed side consisting of multiple shortwave stations (also known as a shortwave fixed station system) and a mobile side consisting of multiple shortwave mobile users (also known as a wireless side). The shortwave fixed station system provides wireless coverage, network access, business communication and other functions for shortwave mobile users with shortwave wireless communication capabilities. Among them, network access refers to the shortwave wireless communication interaction between the mobile shortwave users on the mobile side and one or more of the multiple shortwave stations, thereby obtaining business communication capabilities or qualifications in the entire network system.

[0037] The shortwave stations on the fixed side are mainly composed of shortwave antennas, shortwave receivers, shortwave transmitters, shortwave signal processing equipment, etc., and generally use fixed infrastructure with high-power and large antennas; the shortwave mobile users on the mobile side are mainly composed of shortwave antennas, shortwave radio stations, etc., and generally use small antennas and low-power mobile communication devices (such as shortwave communication vehicles, etc.).

[0038] Figure 1 It is a structural diagram of the short-wave networking communication system in the related technology, such as Figure 1 As shown, in the related art, the shortwave networking communication system mainly adopts the shortwave network access method. The fixed side is composed of multiple shortwave stations interconnected by a wired network, and each shortwave station is interconnected in real time through a wired connection.

[0039] The fixed side is generally divided into two levels of sites. The first level site is the processing center, and the second level site is the access site such as shortwave station A, shortwave station B and shortwave station C. The processing center connects and controls multiple shortwave stations through wired means to provide network access services for shortwave mobile user 1, shortwave mobile user 2 and other users on the wireless side. When a shortwave mobile user accesses the wireless network, the second level access site aggregates the received information to the first level processing center, which makes a decision on network access and then controls the second level site to respond. Through two-way interaction and information exchange between the mobile side and the fixed side, frequency allocation, access authentication and other tasks are completed, thereby obtaining the communication service capability of the entire network.

[0040] However, the disadvantage of shortwave relying on network access is that it requires all shortwave stations on the fixed side to maintain real-time wired network connection, especially the wired network connection of the processing center. Once the wired network fails, the entire shortwave fixed station system will not be able to provide network access and business communication guarantee services for shortwave mobile users on the wireless side. In view of the positioning of shortwave communication as a guaranteed communication, the system composition relying on the wired network will lose the ability to guarantee communication in the event of a major disaster or military war once the wired network facilities are destroyed.

[0041] In view of this, the present invention provides a shortwave communication network access method, device, system, equipment and storage medium to solve at least one of the above-mentioned technical problems.

[0042] Figure 2 It is one of the flow charts of the shortwave communication network access method provided by the present invention, such as Figure 2 As shown, the method is applied to a first shortwave communication device providing network access, including but not limited to steps 201 to 203.

[0043] The first shortwave communication equipment refers to the fixed shortwave communication equipment on the fixed side of the shortwave networking communication system used to provide network access, wireless coverage, business communication and other communication services. It mainly includes shortwave stations composed of shortwave antennas, shortwave receivers, shortwave transmitters, shortwave signal processing equipment, etc., and generally adopts fixed infrastructure with high-power and large antennas.

[0044] Step 201: Receive a first uplink signal broadcast by a second shortwave communication device requesting to access the network.

[0045] The second shortwave communication equipment refers to the shortwave communication equipment requesting access to the shortwave communication network, including but not limited to mobile shortwave communication equipment such as shortwave mobile users on the mobile side and fixed shortwave communication equipment such as shortwave stations on the fixed side.

[0046] When the second shortwave communication device is a mobile shortwave communication device such as a shortwave mobile user on the mobile side, the shortwave mobile user can access the shortwave communication network where the first shortwave communication device is located through the shortwave communication network access method provided by the present invention, and use the communication service provided by the first shortwave communication device; when the second shortwave communication device is a fixed shortwave communication device such as a shortwave station on the fixed side, the shortwave stations can be interconnected through the shortwave communication network access method provided by the present invention.

[0047] The first uplink signal refers to a request signal for the second shortwave communication device to access the shortwave communication network where the first shortwave communication device is located and obtain the qualification to use the communication service provided by the first shortwave communication device.

[0048] Specifically, the second shortwave communication device requesting to access the network initiates the broadcast of the first uplink signal on the communication frequency Fu, and the first shortwave communication device providing network access within the broadcast range receives the first uplink signal.

[0049] It can be understood that there may be more than two first shortwave communication devices within the broadcast range of the first uplink signal, and at this time each first shortwave communication device can receive the first uplink signal.

[0050] Step 202: Send a downlink response signal.

[0051] The communication frequency of the downlink response signal is determined based on the communication frequency of the first uplink signal, a first offset frequency value, and a second offset frequency value.

[0052] The first offset frequency value is determined based on the identity code of the first shortwave communication device.

[0053] The second offset frequency value is determined from a pre-planned offset frequency value table based on the identity code of the second shortwave communication device.

[0054] The downlink response signal is a confirmation signal returned by the first shortwave communication device to the second shortwave communication device after the first shortwave communication device receives the first uplink signal broadcast by the second shortwave communication device on the communication frequency, indicating that the network where the first shortwave communication device is located can be accessed at the communication frequency.

[0055] Specifically, after the first shortwave communication device receives the first uplink signal, it parses the identity code of the second shortwave communication device from the first uplink signal, and determines the second offset frequency value from the pre-planned offset frequency value table stored in the first shortwave communication device according to the identity code. At the same time, after the first shortwave communication device receives the first uplink signal, it determines the first offset frequency value according to the identity code carried by itself. . Using the communication frequency Fu of the first uplink signal and the first offset frequency value and the second offset frequency value , the communication frequency Fd of the downlink response signal can be determined.

[0056] For example, the communication frequency Fu of the first uplink signal and the first offset frequency value and the second offset frequency value The sum is taken as the communication frequency Fd of the downlink response signal.

[0057] For another example, the communication frequency Fu of the first uplink signal and the first offset frequency value and the second offset frequency value The result of the weighted sum is used as the communication frequency Fd of the downlink response signal.

[0058] It should be noted that the identity code is a unique code that identifies a shortwave communication device. The identity code of each first shortwave communication device is different, and the first offset frequency value determined based on the identity code of the first shortwave communication device is also different; the identity code of each second shortwave communication device is different, and the second offset frequency value determined based on the identity code of the second shortwave communication device is also different.

[0059] Therefore, even if different second shortwave communication devices send a first uplink signal to the first shortwave communication device at the same communication frequency, the first shortwave communication device can send a downlink response signal to different second shortwave communication devices at different communication frequencies based on the different identity codes of different second shortwave communication devices, thereby avoiding co-frequency interference.

[0060] Optionally, the pre-planned offset frequency value table includes an identity code field of a second shortwave communication device and a second offset frequency value field; the table records of the offset frequency value table record the identity codes of all second shortwave communication devices allowed to access the shortwave communication network and their corresponding second offset frequency values.

[0061] Optionally, the pre-planned offset frequency value table includes an identity code field of the first shortwave communication device, a first offset frequency value field, an identity code field of the second shortwave communication device, and a second offset frequency value field. In this case, the table record of the offset frequency value table also records the identity codes of all first shortwave communication devices that can be used to provide network access in the shortwave communication network and their corresponding first offset frequency value fields, so as to facilitate simultaneous determination of the first offset frequency value and the second offset frequency value directly from the offset frequency value table according to the identity code.

[0062] In one embodiment, before receiving the first uplink signal broadcast by the second shortwave communication device requesting to access the network, it is determined whether the shortwave network access mode cannot provide the shortwave communication network access service. If so, the communication frequency of the downlink response signal is determined based on the communication frequency of the first uplink signal, the first offset frequency value and the second offset frequency value, and the downlink response signal is sent.

[0063] Step 203: Receive a second uplink signal from the second shortwave communication device to confirm that the second shortwave communication device is connected to the shortwave communication network.

[0064] The second uplink signal is broadcasted by the second shortwave communication device after receiving the downlink response signal.

[0065] The second uplink signal is a reconfirmation signal generated and broadcasted by the second shortwave communication device after receiving the downlink response signal sent by the first shortwave communication device, confirming that the second shortwave communication device can access the shortwave communication network at the current communication frequency.

[0066] Specifically, after receiving the downlink response signal, the second shortwave communication device generates a second uplink signal and initiates the broadcast of the second uplink signal on the communication frequency Fu. After the first shortwave communication device receives the second uplink signal, the second shortwave communication device can be connected to the shortwave communication network to confirm that the second shortwave communication device is qualified to use the communication service provided by the first shortwave communication device. After the first shortwave communication device confirms that the second shortwave communication device is connected to the shortwave communication network, the second shortwave communication device can use the connected shortwave communication network to transmit and communicate business data.

[0067] Figure 3 is one of the example diagrams of the shortwave communication network access method provided by the present invention, such as Figure 3 As shown, in one embodiment, there are two second shortwave communication devices on the mobile side, namely shortwave mobile user 1 and shortwave mobile user 2, and there is one first shortwave communication device on the fixed side, namely shortwave station A.

[0068] When two second shortwave communication devices on the mobile side request to access the shortwave communication network, shortwave mobile user 1 broadcasts a first uplink signal ① on the communication frequency Fu1, and shortwave mobile user 2 broadcasts a first uplink signal ④ on the communication frequency Fu2.

[0069] After receiving the first uplink signal ①, the shortwave station A changes the communication frequency Fu1 of the first uplink signal ① and the first offset frequency value determined according to the identity code of the shortwave station A. and a second offset frequency value determined according to the identity code of the shortwave mobile user 1 The sum of the two is used as the communication frequency Fd1 of the downlink response signal ②.

[0070] After receiving the first uplink signal ④, the shortwave station A changes the communication frequency Fu2 of the first uplink signal ④ and the first offset frequency value determined according to the identity code of the shortwave station A. and a second offset frequency value determined according to the identity code of the shortwave mobile user 2 The sum of them is used as the communication frequency Fd2 of the downlink response signal ⑤.

[0071] It can be seen that based on the different shortwave mobile user identity codes, the second offset frequency value and are different, and the communication frequency Fd1 and the communication frequency Fd2 are also different.

[0072] Shortwave station A sends a downlink response signal ② to shortwave mobile user 1 on the communication frequency Fd1, and sends a downlink response signal ⑤ to shortwave mobile user 2 on the communication frequency Fd2.

[0073] After receiving the downlink response signal ②, shortwave mobile user 1 broadcasts the second uplink signal ③ on the communication frequency Fu1, and after receiving the downlink response signal ⑤, shortwave mobile user 2 broadcasts the second uplink signal ⑥ on the communication frequency Fu2. After receiving the second uplink signal ③ and the second uplink signal ⑥, shortwave station A can confirm that shortwave mobile user 1 and shortwave mobile user 2 are connected to the shortwave communication network.

[0074] Figure 4 FIG. 2 is a second example of the shortwave communication network access method provided by the present invention. Figure 4 As shown, in one embodiment, there is a second shortwave communication device on the mobile side, which is a shortwave mobile user, and there are three first shortwave communication devices on the fixed side, which are shortwave station A, shortwave station B and shortwave station C.

[0075] When the second shortwave communication device on the mobile side requests to access the shortwave communication network, the shortwave mobile user broadcasts a first uplink signal ① at the communication frequency Fu.

[0076] After receiving the first uplink signal ①, the shortwave station A changes the communication frequency Fu of the first uplink signal ① and the first offset frequency value determined according to the identity code of the shortwave station A to and a second offset frequency value determined according to the identity code of the shortwave mobile user The sum of the two is used as the communication frequency Fd1 of the downlink response signal ②.

[0077] After receiving the first uplink signal ①, the shortwave station B changes the communication frequency Fu of the first uplink signal ① and the first offset frequency value determined according to the identity code of the shortwave station B to and a second offset frequency value determined according to the identity code of the shortwave mobile user The sum of the two is used as the communication frequency Fd2 of the downlink response signal ③.

[0078] After receiving the first uplink signal ①, the shortwave station C converts the communication frequency Fu of the first uplink signal ① and the first offset frequency value determined according to the identity code of the shortwave station C into and a second offset frequency value determined according to the identity code of the shortwave mobile user The sum is used as the communication frequency Fd3 of the downlink response signal ④.

[0079] It can be seen that based on the different identity codes of shortwave stations, the first offset frequency value , and are different, and the communication frequencies Fd1, Fd2 and Fd3 are also different.

[0080] After shortwave station A, shortwave station B, and shortwave station C send downlink response signals ②, ③, and ④ to the shortwave mobile user on communication frequencies Fd1, Fd2, and Fd3, the shortwave mobile user broadcasts the second uplink signal ⑤ on the communication frequency Fu. After shortwave station A, shortwave station B, and shortwave station C receive the second uplink signal ⑤, they determine that the shortwave mobile user joins their respective shortwave communication networks.

[0081] Furthermore, in a shortwave communication network access scenario, there are often an indefinite number of first shortwave communication devices providing network access and an indefinite number of second shortwave communication devices requesting network access. When pre-planning the offset frequency value table, the communication frequencies of the downlink response signals sent by the first shortwave communication devices are all different, and the first offset frequency values ​​corresponding to different first shortwave communication devices and the second offset frequency values ​​corresponding to different second shortwave communication devices are determined.

[0082] The shortwave communication network access method provided by the present invention, when executing the access operation of the shortwave communication network, no longer aggregates the uplink request signal to the primary processing center site on the fixed side before making a decision on network access, but the shortwave station or the like that receives the uplink request signal directly responds to the uplink request signal, so that the network access operation no longer depends on the wired communication connection between the primary site and the secondary site on the fixed side, and a network access method without support is realized. Even if the wired network facilities are destroyed, as long as there is a shortwave station that operates well, it can provide communication connection services for the shortwave communication users on the mobile side, giving full play to the bottom line of shortwave communication. Communication capability; by determining different communication frequencies for downlink response signals sent by different shortwave communication devices on the fixed side to different shortwave communication devices on the mobile side according to the different identity codes of the medium and shortwave communication devices on the mobile side, it is ensured that each downlink response signal does not conflict with each other, and avoids the simultaneous transmission of multiple downlink response signals on the same frequency to cause co-frequency interference, thereby realizing a network access method without co-frequency interference; by providing three-way signal interactions between the first shortwave communication device for network access and the second shortwave communication device for requesting network access, the security and reliability of communication frequency selection and wireless network access during network access without support are ensured.

[0083] Based on the above embodiment, as an optional embodiment, there are more than two first shortwave communication devices, and the communication connection between any two first shortwave communication devices is established by wireless communication connection.

[0084] Specifically, in a shortwave communication network access scenario, there are more than two first shortwave communication devices, and the communication connection between any two first shortwave communication devices is established by wireless communication connection. Before establishing a wireless communication connection between any two first shortwave communication devices, the shortwave communication network access method provided in any of the above embodiments can be used to realize the networking and communication connection between any two first shortwave communication devices.

[0085] Taking the shortwave station A on the fixed side as an example, if shortwave station A needs to establish a wireless communication connection with shortwave station B on the fixed side, shortwave station A, as the second shortwave communication device, initiates the first uplink signal with a communication frequency of Fu to shortwave station B within the broadcast range. At this time, shortwave station B is the first shortwave communication device. Shortwave station B receives the first uplink signal, determines the first offset frequency value according to its own identity code, and determines the second offset frequency value from the pre-planned offset frequency value table according to the identity code of shortwave station A, and then determines the communication frequency of the downlink response signal and sends it to shortwave station A. After receiving the downlink response signal, shortwave station A broadcasts the second uplink signal with a communication frequency of Fu. After receiving the second uplink signal, shortwave station B determines to form a network with shortwave station A.

[0086] After shortwave station A and shortwave station B establish a wireless network connection, they can both serve as the first shortwave communication device to process connection requests from other fixed-side shortwave stations or mobile-side shortwave mobile users to complete network access.

[0087] It can be understood that, for the shortwave communication device on the fixed side such as a shortwave station, the first offset frequency value when it serves as the first shortwave communication device and the second offset frequency value when it serves as the second shortwave communication device can be the same or different.

[0088] That is to say, if the pre-planned offset frequency value table includes the identity code field of the first shortwave communication device and the identity code field of the second shortwave communication device, there may be two different table records in the offset frequency value table, and the value of the identity code field of the first shortwave communication device in one of the table records is the same as the value of the identity code field of the second shortwave communication device in the other table record.

[0089] In the network access method, shortwave stations interconnected by wire can use the high bandwidth, high speed and high reliability of the wired network to achieve rapid exchange of big data information, such as contact files, configuration files, pictures, compressed packages, voice, video and other relatively large data.

[0090] In the network-free access mode, if there is no wired connection between shortwave stations, but information is exchanged through shortwave wireless channels, the data transmission rate is strictly limited by the bandwidth and rate of the shortwave wireless channels. The transmission bit rate of the shortwave wireless channel is generally between tens and thousands, and factors such as environment, time, and interference cause interference to the shortwave wireless channel. The above reasons combined make the data transmission capacity of the shortwave wireless channel far lower than that of the wired network.

[0091] The shortwave communication network access method provided by the present invention adopts wireless communication connection when two or more first shortwave communication devices establish a communication mode, that is, adopts a non-supported mode that does not rely on a wired network, in order to avoid the support mode being destroyed in an emergency situation of a major disaster or military war, resulting in the loss of the guaranteed communication capacity of the shortwave communication; if the communication capacity of the first shortwave communication device is greatly affected after the wireless communication connection is established, then the first shortwave communication devices are used to transmit short control instructions, including but not limited to status parameter query and reporting, remote control restart or self-test, etc.

[0092] Based on the above embodiment, as an optional embodiment, the receiving of the first uplink signal broadcast by the second shortwave communication device requesting to access the network further includes: If the first shortwave communication device does not receive the designated first uplink signal broadcast by the second shortwave communication device within the first preset time period, it is determined that the second shortwave communication device has failed to access the shortwave communication network.

[0093] The designated first uplink signal is a first uplink signal broadcast on a pre-designated communication frequency.

[0094] The first preset time length is a maximum time length used to determine whether the second shortwave communication device successfully accesses the shortwave communication network.

[0095] The communication frequency of the first uplink signal broadcast by the second shortwave communication device is often selected in sequence from a pre-planned communication frequency table. The designated first uplink signal can be either the first uplink signal broadcast on the first communication frequency in the communication frequency table or the first uplink signal broadcast on several specific communication frequencies in the communication frequency table.

[0096] Specifically, when the first shortwave communication device triggers the reception of the first uplink signal, a timer is also started. If the designated first uplink signal is a first uplink signal broadcasted on the first communication frequency in the communication frequency table, if the first shortwave communication device does not receive the designated first uplink signal within the first preset time, it indicates that the second shortwave communication device cannot reach the location of an emergency such as a major disaster in time, and it is confirmed that the second shortwave communication device has failed to access the shortwave communication network.

[0097] If the designated first uplink signal is a first uplink signal broadcast on several specific communication frequencies in the communication frequency table, if the first shortwave communication device does not receive all the designated first uplink signals within the first preset time period, it indicates that the second shortwave communication device cannot complete the relevant emergency tasks of major disasters through the designated communication frequency, and it is confirmed that the second shortwave communication device has failed to access the shortwave communication network.

[0098] Optionally, the first preset duration is determined according to the signal broadcast radius of the second shortwave communication device, the average distance between the first shortwave communication device and the second shortwave communication device, and the average moving speed of the second shortwave communication device.

[0099] If the first shortwave communication device does not receive the designated first uplink signal broadcast on the first communication frequency in the communication frequency table within the first preset time length, it is confirmed that the second shortwave communication device has failed to access the shortwave communication network where the first shortwave communication device is located.

[0100] It can be understood that, for different second shortwave communication devices and designated first uplink signals, different first shortwave communication devices may plan in advance different first preset durations.

[0101] The shortwave communication network access method provided by the present invention can enable the first shortwave communication device to automatically count the presence of emergency forces in emergency situations such as major disasters or military wars by confirming whether the second shortwave communication device has successfully or failed to access the shortwave communication network, by simultaneously specifying the communication frequency and the total timeout time when accessing the communication network.

[0102] Based on the above embodiment, as an optional embodiment, after receiving the second uplink signal of the second shortwave communication device to confirm that the second shortwave communication device is connected to the shortwave communication network, the method further includes: Receiving business communication data sent by a second shortwave communication device; forwarding the business communication data to another second shortwave communication device; The one second shortwave communication device and the another second shortwave communication device are both connected to the shortwave communication network.

[0103] Specifically, after confirming through three two-way interactions that the second shortwave communication device is connected to the shortwave communication network where the first shortwave communication device is located, it is further determined whether the first shortwave communication device is connected to more than two second shortwave communication devices. If so, the first shortwave communication device can forward the business communication data to another second shortwave communication device of the target after receiving the business communication data sent by a second shortwave communication device, thereby realizing business communication between the two second shortwave communication devices after networking.

[0104] Figure 5 FIG. 3 is a third example of the shortwave communication network access method provided by the present invention. Figure 5 As shown, shortwave mobile user 1 and shortwave mobile user 2 are both second shortwave communication devices, and shortwave station A, shortwave station B, shortwave station C, shortwave station D and shortwave station E are all first shortwave communication devices. Among them, shortwave mobile user 1 accesses shortwave station A, shortwave station B and shortwave station C through point-to-network frequency selection, and shortwave mobile user 2 accesses shortwave station C, shortwave station D and shortwave station E through point-to-network frequency selection. That is, the first shortwave communication device shortwave station C is connected to more than two second shortwave communication devices at the same time, and the access information of shortwave mobile user 1 and shortwave mobile user 2 is stored at the same time. Due to reasons such as the long distance, shortwave mobile user 1 cannot directly communicate wirelessly with shortwave mobile user 2, so business communication is carried out through the public access shortwave station C.

[0105] Shortwave mobile user 1 sends the business communication data to the target user shortwave mobile user 2 to shortwave station A, shortwave station B and shortwave station C. Since only shortwave station C stores the access information of shortwave mobile user 2, only shortwave station C can forward the business communication data. After shortwave station C forwards the business communication data to shortwave mobile user 2, the business communication between shortwave mobile user 1 and shortwave mobile user 2 is realized.

[0106] Similarly, when shortwave mobile user 2 wants to communicate with the target user shortwave mobile user 1, it sends the business communication data to shortwave station C, shortwave station D and shortwave station E. Only shortwave station C forwards the business communication data to shortwave mobile user 1, thus realizing the business communication between shortwave mobile user 1 and shortwave mobile user 2.

[0107] The shortwave communication network access method provided by the present invention utilizes the characteristic that the first shortwave communication device stores the access information of the second shortwave communication device accessing the network. When the physical distance between the two second shortwave communication devices is too far, the first shortwave communication device accessing together receives and forwards the service communication data between the two second shortwave communication devices, thereby realizing the wide area access of the point-to-network frequency selection and non-reliant network access mode.

[0108] Figure 6 FIG. 2 is a flow chart of the shortwave communication network access method provided by the present invention. Figure 6 As shown, the shortwave communication network access method is applied to a second shortwave communication device requesting to access the network, including but not limited to steps 601 to 603.

[0109] Step 601: Broadcast a first uplink signal.

[0110] Step 602: Receive a downlink response signal sent by a first shortwave communication device that provides network access; the communication frequency of the downlink response signal is determined based on the communication frequency of the first uplink signal, a first offset frequency value and a second offset frequency value; the first offset frequency value is determined based on the identity code of the first shortwave communication device; the second offset frequency value is determined from a pre-planned offset frequency value table based on the identity code of the second shortwave communication device.

[0111] Step 603: broadcast a second uplink signal so that the first shortwave communication device can confirm that the second shortwave communication device is connected to the shortwave communication network after receiving the second uplink signal.

[0112] It should be noted that the shortwave communication network access method provided in this embodiment for a second shortwave communication device requesting network access, during specific operation, corresponds to the shortwave communication network access method for a first shortwave communication device providing network access described in any of the above embodiments, which is not elaborated in this embodiment.

[0113] The shortwave communication network access method provided by the present invention, when executing the access operation of the shortwave communication network, no longer aggregates the uplink request signal to the primary processing center site on the fixed side before making a decision on network access, but the shortwave station or the like that receives the uplink request signal directly responds to the uplink request signal, so that the network access operation no longer depends on the wired communication connection between the primary site and the secondary site on the fixed side, and a network access method without support is realized. Even if the wired network facilities are destroyed, as long as there is a shortwave station that operates well, it can provide communication connection services for the shortwave communication users on the mobile side, giving full play to the bottom line of shortwave communication. Communication capability; by determining different communication frequencies for downlink response signals sent by different shortwave communication devices on the fixed side to different shortwave communication devices on the mobile side according to the different identity codes of the medium and shortwave communication devices on the mobile side, it is ensured that each downlink response signal does not conflict with each other, and avoids the simultaneous transmission of multiple downlink response signals on the same frequency to cause co-frequency interference, thereby realizing a network access method without co-frequency interference; by providing three-way signal interactions between the first shortwave communication device for network access and the second shortwave communication device for requesting network access, the security and reliability of communication frequency selection and wireless network access during network access without support are ensured.

[0114] Based on the above embodiment, as an optional embodiment, the receiving of a downlink response signal sent by a first shortwave communication device providing network access includes: Within a second preset time period, diversity receiving two or more downlink response signals sent by different first shortwave communication devices; The two or more downlink response signals are combined to broadcast a second uplink signal after the second preset time period.

[0115] The second preset duration is a maximum duration used to determine whether a received downlink response signal is a useful signal.

[0116] Diversity reception refers to a method in which the receiving end performs specific merging processing on multiple independent fading characteristic signals carrying the same information to reduce signal level fluctuations.

[0117] Specifically, after the second shortwave communication device broadcasts the same first uplink signal, all different first shortwave communication devices that can receive the first uplink signal can generate downlink response signals with different communication frequencies.

[0118] Furthermore, the second shortwave communication device receives more than two downlink response signals sent by different first shortwave communication devices in a diversity reception manner within a second preset time period, and merges all downlink response signals received within the second preset time period, so as to broadcast the second uplink signal after the second preset time period has passed.

[0119] It can be understood that when there are more than two first shortwave communication devices, since the first shortwave communication devices sending the downlink response signals are different, the communication frequencies of the more than two downlink response signals are different.

[0120] It can be understood that the downlink response signal is a response to the first uplink signal broadcast by the same second shortwave communication device, so the downlink response signals sent by different first shortwave communication devices on different communication frequencies carry the same information.

[0121] Optionally, the second preset duration is determined according to a maximum distance between different first shortwave communication devices and the same second shortwave communication device, and a propagation speed of the second uplink signal.

[0122] The shortwave communication network access method provided by the present invention takes into account the difference in physical distances between different first shortwave communication devices and the second shortwave communication device that broadcasts the first uplink signal, which will cause a certain time deviation in the downlink responses sent by the different first shortwave communication devices. Therefore, a second preset time length acceptable to the mobile side is set on the second shortwave communication device side. As long as the downlink response information received by the second shortwave communication device within the second preset time length is received as a useful signal; and when receiving the downlink response signals sent by different first shortwave communication devices at different communication frequencies, a diversity reception method is adopted, and through diversity combining processing, the influence of attenuation of different signals can be reduced, thereby improving the overall receiving effect of the second shortwave communication device.

[0123] Based on the above embodiment, as an optional embodiment, the receiving of the downlink response signal sent by the first shortwave communication device providing network access further includes: If the second shortwave communication device does not receive any downlink response signal within the third preset time period, the communication frequency is updated and the process returns to the step of broadcasting the first uplink signal.

[0124] The third preset duration is a maximum duration used to determine whether the current communication frequency can access the shortwave communication network.

[0125] Specifically, after the second shortwave communication device broadcasts the first uplink signal, all first shortwave communication devices within the broadcast range will receive the first uplink signal and send a downlink response signal back to the second shortwave communication device. For the second shortwave communication device, if the second shortwave communication device does not receive any downlink response signal in response to any first shortwave communication device within the third preset time length, it means that any first shortwave communication device cannot be accessed at the current communication frequency, and the communication frequency is updated based on the pre-planned communication frequency change rule, and the step of broadcasting the first uplink signal is returned to, and three two-way interactive point-to-network frequency selection processes are attempted on the updated communication frequency until all replaceable communication frequencies are traversed.

[0126] By analogy, if the second shortwave communication device completes the point-to-network frequency selection process of the non-network access mode through three two-way interactions on a certain updated communication frequency, it is determined that the second shortwave communication device has successfully selected the frequency and accessed the shortwave communication network. If the second shortwave communication device has traversed all replaceable communication frequencies and still has not received any downlink response signal, it is determined that the second shortwave communication device has failed to access the shortwave communication network.

[0127] Optionally, the communication frequency of the second shortwave communication device is determined based on the following expression: ; (1)

[0128] in, For the The communication frequency of the change, is the starting communication frequency, is a fixed interval of communication frequency.

[0129] Optionally, the communication frequency replaced by the second shortwave communication device is the next communication frequency of the current communication frequency in a pre-planned communication frequency table.

[0130] It can be understood that different communication frequency tables are planned in advance according to the difference between the second shortwave communication equipment, such as a mobile shortwave mobile user on the mobile side or a fixed shortwave communication equipment such as a shortwave station on the fixed side, to ensure that the horizontal communication between shortwave stations and the vertical communication between the shortwave station and the shortwave mobile user will not conflict.

[0131] Optionally, different second shortwave communication devices have different communication frequency tables and preferably different communication frequencies; different first shortwave communication devices have different communication frequency tables and preferably different communication frequencies.

[0132] Optionally, for the same second shortwave communication device, the second preset time length is shorter than the third preset time length.

[0133] The shortwave communication network access method provided by the present invention sets a frequency selection timeout mechanism. When the frequency selection times out on a certain communication frequency, i.e., when no downlink response signal is received, the communication frequency will be switched and the three-way interactive point-to-network frequency selection process of trying the network access mode without relying on the network will be repeated until the network is successfully accessed on a certain communication frequency or all replaceable communication frequencies are traversed, thereby increasing the success rate of shortwave communication network access.

[0134] On the whole, the shortwave communication network access method provided by the present invention has no wired connection between the first shortwave communication device and the second shortwave communication device (such as a shortwave mobile user), and between the first shortwave communication devices, except for the wired interconnection between the communication components inside a single first shortwave communication device (such as a shortwave station). Furthermore, the first shortwave communication device provides network access and communication infrastructure, which can realize the wireless interconnection of the second shortwave communication devices on different shortwave wireless channels, and realize the transmission of services and signaling. Through this independent network access method, each shortwave station can independently provide wireless coverage guarantee capabilities for shortwave mobile users. In emergency situations such as major disasters, even if the ground wired network facilities are destroyed or some shortwave stations are destroyed, as long as there are shortwave stations that are working normally, it can still provide communication guarantee capabilities for shortwave mobile users, thereby giving full play to the shortwave guaranteed communication capabilities.
