Description

Technical Field

[0001] The present invention relates to the technical field of shortwave communication, and in particular to a shortwave forwarding control system and method with a unified forwarding address for the entire network. Background Art

[0002] Shortwave communication, also known as high frequency (HF) communication, has the advantages of long communication distance, easy installation and low operating cost. It has long been widely used in ocean-going, aviation, fishery, border and coastal defense, emergency rescue departments and military fields. It is an indispensable wireless medium and long-distance emergency communication method besides satellite communication.

[0003] The shortwave relay system builds a relay mechanism by adding necessary relay equipment without changing the existing point-to-point shortwave communication mode. It solves the problem that the source shortwave user and the target shortwave user cannot communicate directly due to communication blind spots or asymmetric power of the relay shortwave radio station, thereby solving the problem of difficult cross-regional command and coordination communications in the entire network.

[0004] The communication parameters of the shortwave radio stations in each jurisdiction of the existing shortwave relay system are different from the radio addresses and communication frequency sets in other jurisdictions. Therefore, during emergency command and coordinated communication, the shortwave radio stations of the shortwave relay stations in each jurisdiction need to have two sets of communication parameters. The relay operation is relatively complicated, and it is difficult to organize shortwave users to relay across regions. Sometimes, relaying may not be possible due to blind spots. Summary of the invention

[0011] As an embodiment, the shortwave relay stations are interconnected, and the default working state of the shortwave relay station is the relay station frequency set scanning state or the relay station frequency set fixed frequency receiving standby state. The shortwave relay control subsystem is also used to parse the uplink message or voice received by the relay shortwave radio station, perform routing addressing according to the analysis result, select another relay shortwave radio station that is currently out of service as the downlink relay shortwave radio station, and forward the uplink message or voice to the downlink relay shortwave radio station via the shortwave relay station.

[0012] As an embodiment, before the planning and configuration of the radio address of each shortwave relay station, the relay radio frequency set and the user radio frequency set of the shortwave user, the shortwave relay control subsystem is further used to determine the number of the shortwave relay stations and the number of the relay shortwave radio stations corresponding to each shortwave relay station according to the number of the shortwave users; it is also used to determine the distribution location of each shortwave relay station according to a predetermined relay demand and the performance parameters of each relay shortwave radio station; it is also used to determine the relay radio frequency set of each relay shortwave radio station and the user radio frequency set of the shortwave user according to the available frequency database according to the relay demand, the number of the shortwave users, the number of the shortwave relay stations and the preset communication constraints.

[0013] As an embodiment, the planning and configuration of the radio station address of each shortwave relay station, the relay radio station frequency set and the user radio station frequency set of the shortwave user includes: Based on the current communication parameter configuration modes of the shortwave relay station and the shortwave user, the radio station address, the relay radio station frequency set and the user radio station frequency set are respectively sent to the shortwave relay station and the shortwave user to complete the configuration.

[0026] 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.

[0027] It should be noted that all actions of acquiring signals, information or data in the present invention are performed in compliance with the corresponding data protection laws and policies of the location and with the authorization given by the owner of the corresponding device.

[0028] The problems that need to be solved urgently in the existing shortwave signal relay system are as follows: 1) The overall service capability of the system is weak: the shortwave relay stations of the existing shortwave relay system do not have unified access relay network parameters. The radio addresses and relay frequency sets of the shortwave relay stations are different. The shortwave relay stations in each jurisdiction can only serve the shortwave users in the jurisdiction. Shortwave users can only access the shortwave relay stations in their jurisdiction and cannot access other shortwave relay stations in the shortwave relay system at will. The overall service capability of the system is weak.

[0029] 2) There may be blind spot problems: Since shortwave users can only call a single designated shortwave relay station, and the power of the shortwave users and the shortwave relay stations is not equal and only one-way communication is possible, or there may be blind spot problems when the two communicate point-to-point, the source shortwave user cannot achieve relay communication with the target shortwave user through the designated shortwave relay station.

[0030] 3) Difficulty in communication organization and application: Since the communication parameters of the source shortwave user are only consistent with the communication parameters of the shortwave relay station in the corresponding jurisdiction, when the shortwave user performs a collaborative task across regions, its relay shortwave radio station must temporarily change the communication parameters to establish a link and communicate with the relay shortwave radio station of the shortwave relay station in the mission area. In addition, when there is a communication blind spot between the target shortwave user and the source shortwave user, the communication frequency sets of the source and target shortwave users need to be changed synchronously so that both parties can achieve relay communication, which is bound to increase the difficulty of collaborative communication operations.

[0031] Figure 1 This is one of the structural diagrams of an embodiment of an existing shortwave signal relay system. Figure 2 This is one of the schematic diagrams of the business channels of the existing shortwave relay system. Figure 3 This is the second schematic diagram of the business channel of the existing shortwave signal relay system. Figure 1-Figure 3 As shown, in the existing shortwave relay system, shortwave users correspond one to one with the relaying shortwave radio stations, and cross-region communication can only be achieved through forwarding by the corresponding shortwave relay stations.

[0032] Figure 4 This is a second structural diagram of an embodiment of an existing shortwave signal relay system. Figure 4 As shown, the addresses of the shortwave radio stations 1-6 in the existing shortwave relay system are respectively 101 to 106, and the corresponding frequency sets are F1 to F6. The addresses of the shortwave users are respectively 201 to 206, and the corresponding frequency sets are F1 to F6. The frequency set F1 = {f11, f12, f13, f14, f15, f16}, and the frequency set F2 = {f21, f22, f23, f24, f25, f26}, frequency set F3 = {f31, f32, f33, f34, f35, f36}, frequency set F4 = {f41, f42, f43, f44, f45, f46}, frequency set F5 = {f51, f52, f53, f54, f55, f56}, frequency set F6 = {f61, f62, f63, f64, f65, f66}, there are at least the following deficiencies.

[0033] 1) The radio addresses of various shortwave relay stations are not unified, and shortwave users must configure multiple shortwave relay station addresses.

[0034] 2) The shortwave user has the same frequency set as one of the shortwave relay stations to which he belongs, and can only access the relay shortwave radio station.

[0035] 3) Shortwave users have no intersection with other shortwave radio stations of their shortwave relay stations. Without replanning the communication parameters, any radio station in the station cannot be connected to the relay at any time, and the relay organization within the station is not flexible.

[0036] 4) There is no intersection between the frequency sets of shortwave users and other shortwave relay stations. Without replanning the communication parameters, cross-regional relay cannot be realized at any time, and cross-regional relay organization and coordination are difficult.

[0037] The present invention provides a shortwave signal forwarding control system and method with a unified signal forwarding address for the entire network, which will be described in detail below in conjunction with the accompanying drawings.

[0038] Figure 5 : is a schematic diagram of the structure of a shortwave signal forwarding control system with a unified signal forwarding address for the entire network provided by the present invention. Figure 5As shown, the present invention provides a shortwave signal forwarding control system with a unified signal forwarding address for the entire network, comprising: at least one shortwave signal forwarding control subsystem, at least one shortwave signal forwarding station communicatively connected to each of the shortwave signal forwarding control subsystems, and at least two signal forwarding shortwave radio stations communicatively connected to each of the shortwave signal forwarding stations. The signal forwarding shortwave radio station can provide voice, message or voice signal forwarding services for a number of shortwave users.

[0039] The shortwave relay control subsystem is used to plan and configure the radio address of each shortwave relay station, the relay radio frequency set and the user radio frequency set of the shortwave user. The radio address of each shortwave relay station is the same, and the relay radio frequency set is orthogonal to the user radio frequency set.

[0040] When shortwave users do not need to communicate with multiple users simultaneously in two-way, from the perspective of economy, scope of protection, etc., the number of shortwave relay stations can be appropriately reduced, and can be reduced to at least one shortwave relay station (equipped with two sets of relay shortwave radio stations), or reduced to two shortwave relay stations (each shortwave relay station is equipped with a set of relay shortwave radio stations). If it is necessary to realize multi-user concurrent two-way communication, each shortwave relay station is equipped with at least two sets of relay shortwave radio stations. The number of shortwave relay stations in the embodiment of the present invention can be planned and transformed (or constructed) according to the actual number of concurrent users that need to be supported by the relay. Generally, in order to support 2N shortwave users to conduct two-way voice relay communication in pairs at the same time, the number of relay shortwave radio stations of the shortwave relay system should be at least 2N. Assuming that each shortwave relay station is equipped with 2 relay shortwave radio stations, the number of shortwave relay stations of the shortwave relay system is N. Figure 5 An example of site planning and communication parameter planning for the reconstruction (or construction) of a shortwave relay system that supports two-way voice communication for six shortwave users is given. In order to support two-way voice communication between six shortwave users, the system needs to be configured with at least six relay shortwave radio stations. Three shortwave relay stations can be planned, and each shortwave relay station is equipped with two relay shortwave radio stations.

[0041] The shortwave user can be a front emergency user, a rear command user, or both of them can be front emergency users. The shortwave forwarding control system with a unified forwarding address for the entire network provided by the present invention is used for emergency shortwave wireless forwarding communication when shortwave users cannot communicate directly, but both can wirelessly interconnect with a shortwave forwarding station and a forwarding shortwave radio station in a shortwave forwarding control system with a unified forwarding address for the entire network through shortwave point-to-point communication.

[0042] It can be understood that the present invention configures the relay radio frequency set and the user radio frequency set orthogonally, and configures the radio addresses of the shortwave relay stations in the entire network to be the same address. Shortwave users do not need to configure multiple shortwave relay station addresses. They only need to call the unified and unique relay address of the entire network to access a shortwave relay station in the network through the user radio frequency. The entire network does not need to re-plan communication parameters to support cross-region relay communications for each shortwave user, thereby solving the problems of complex relay operations, difficult cross-region relay organization, and even the defect of being unable to relay due to blind spots.

[0043] On the basis of the above embodiment, as an optional embodiment, the frequencies of the relay station frequency set correspond one-to-one to the frequencies of the user station frequency set, and the relay station frequency set and the user station frequency set both include multiple communication frequencies or communication frequency subsets, and the number of communication frequencies is greater than or equal to the number of the relay shortwave stations; the number of communication frequencies of each shortwave relay station and shortwave user can be expanded as needed, for example, the communication frequency subset is obtained by expanding the communication frequency according to the usage period or the main and backup attribute rules of the frequency.

[0044] Optionally, the shortwave relay control subsystem is also used to construct a relay station frequency matrix based on all the relay station frequency sets, and to construct a user station frequency matrix based on all the user station frequency sets, wherein the row elements of the relay station frequency matrix are the column elements of the user station frequency matrix, and the row elements of the user station frequency matrix are the column elements of the relay station frequency matrix, so as to achieve orthogonality between the relay station frequency set and the user station frequency set.

[0045] like Figure 6 As shown, suppose the user radio frequency sets corresponding to shortwave users 1-6 are F1-F6, F1={f11, f12, f13, f14, f15, f16}…F6={f61, f62, f63, f64, f65, f66}, and the forwarding radio frequency sets corresponding to the forwarding shortwave radio stations 1-6 are F1'-F6', F1'={f11, f21, f31, f41, f51, f61}…F6'={f16, f26, f36, f46, f56, f66}. It can be seen that the forwarding radio frequency set is orthogonal to the user radio frequency set.

[0046] In order to enhance practicality, each communication frequency f ij as a frequency subset, and then each frequency in the subset can be used according to the daytime frequency (daily frequency) f ij日 , Night frequency (night frequency) f ij夜 and the backup frequency f ij备 To expand, that is, each f ij ={ f ij日 , f ij夜, f ij备}.

[0047] It can be understood that the present invention constructs a communication frequency set matrix between shortwave users and relay shortwave radio stations so that the relay radio station frequency set is orthogonal to the user radio station frequency set. Each shortwave user can initiate a call to the relay shortwave radio station corresponding to the shortwave relay station in any partition of the wide-area distribution, thereby solving the shortwave communication blind spot problem between the existing shortwave relay system and shortwave users.

[0048] On the basis of the above embodiment, as an optional embodiment, before the planning and configuration of the radio address of each shortwave relay station, the relay radio frequency set and the user radio frequency set of the shortwave user, the shortwave relay control subsystem is further used to determine the number of the shortwave relay stations and the number of the relay shortwave radio stations corresponding to each shortwave relay station according to the number of the shortwave users; it is also used to determine the distribution position of each shortwave relay station according to the predetermined relay demand and the performance parameters of each relay shortwave radio station; it is also used to determine the relay radio frequency set of each relay shortwave radio station and the user radio frequency set of the shortwave user according to the available frequency database according to the relay demand, the number of the shortwave users, the number of the shortwave relay stations and the preset communication constraints.

[0049] Optionally, the planning and configuration of the radio address of each shortwave relay station, the relay radio frequency set and the user radio frequency set of the shortwave user includes: based on the current communication parameter configuration mode of the shortwave relay station and the shortwave user, respectively sending the radio address, the relay radio frequency set and the user radio frequency set to the shortwave relay station and the shortwave user to complete the configuration.

[0050] The present invention does not change the service types originally supported by the shortwave users and the shortwave relay system, the point-to-point link establishment mode and the wireless communication mode of the relayed shortwave radio station, nor does it change the existing shortwave relay system interface protocol (including the air interface protocol) and business process, so it is convenient to upgrade the existing shortwave relay system.

[0051] Based on the above embodiment, as an optional embodiment, the shortwave user includes a shortwave communication terminal and a user shortwave radio station connected to the shortwave communication terminal, and the default working state of the user shortwave radio station is a user radio station frequency set scanning state or a user radio station frequency set fixed frequency receiving standby state.

[0052] It can be understood that the user radio station frequency set scanning state can initiate an uplink scanning call to the relay shortwave radio stations in all areas, and the user radio station frequency set fixed-frequency receiving standby state can respond to the downlink scanning call initiated by the relay shortwave radio station in any area, thereby realizing cross-region shortwave communication.

[0053] On the basis of the above embodiment, as an optional embodiment, the shortwave user is used to perform uplink shortwave forwarding or downlink shortwave forwarding based on any communication frequency or communication frequency subset in the user radio frequency set and at most one of the forwarding shortwave radio stations that is orthogonal to the frequency, the uplink shortwave forwarding includes establishing an uplink and uploading uplink messages or voices, and the downlink shortwave forwarding includes establishing a downlink and receiving downlink messages or voices.

[0054] It can be understood that shortwave users can arbitrarily access the shortwave radio of a certain shortwave relay station without frequently changing communication parameters. It is easy to use and can communicate with at most one shortwave radio station, thus avoiding communication conflicts.

[0055] On the basis of the above embodiment, as an optional embodiment, the shortwave relay stations are interconnected, the default working state of the shortwave relay station is the relay station frequency set scanning state or the relay station frequency set fixed frequency receiving standby state, and the shortwave relay control subsystem is also used to parse the uplink message or voice received by the relay shortwave radio station, perform routing addressing according to the analysis result, select the relay shortwave radio station that is currently out of service as the downlink relay shortwave radio station, and forward the uplink message or voice to the downlink relay shortwave radio station via the shortwave relay station.

[0056] It can be understood that the present invention changes the usage mode of point-to-point binding between the shortwave relay station and the shortwave user. Since the shortwave relay stations in the entire network have unified the station addresses, any shortwave user in the network can access a shortwave relay station distributed in a wide area at any time, effectively eliminating the shortwave point-to-point communication blind spot problem in the original system.

[0057] In summary, the present invention adopts a frequency set allocation method based on an orthogonal matrix to allocate communication parameters for shortwave users and shortwave relay stations without changing the existing system interface protocol and business process, thereby realizing the unification of all radio station addresses of the existing shortwave relay system, simplifying the communication network parameters of the existing shortwave relay system, changing the state of shortwave relay stations in the system fighting each other, forming a shortwave wireless relay network, and improving the relay service effect.

[0058] The following describes a shortwave forwarding control method for a unified forwarding address for the entire network provided by the present invention. The shortwave forwarding control method for a unified forwarding address for the entire network described below and the shortwave forwarding control system for a unified forwarding address for the entire network described above can correspond to each other.

[0059] Figure 6 This is one of the flow charts of a shortwave forwarding control method with a unified forwarding address for the entire network provided by the present invention, such as Figure 6As shown, the present invention also provides a shortwave signal forwarding control method with a unified signal forwarding address for the entire network, which is implemented based on any one of the shortwave signal forwarding control systems with a unified signal forwarding address for the entire network, and the method at least includes step S100.

[0060] Step S100, planning and configuring the radio address of each of the shortwave relay stations, the relay radio frequency set and the user radio frequency set of the shortwave user through the shortwave relay control subsystem, the radio address of each of the shortwave relay stations is the same, and the relay radio frequency set is orthogonal to the user radio frequency set.

[0061] Optionally, after the planning and configuration of the radio station address of each shortwave relay station, the relay radio station frequency set and the user radio station frequency set of the shortwave user, steps S200 to S600 are also included.

[0062] Step S200, based on the uplink scanning call initiated by the source shortwave user, under the constraint of the orthogonal frequency set, an uplink shortwave communication link can be established with at most one currently idle relay shortwave radio station, and the currently idle relay shortwave radio station is used as the uplink relay shortwave radio station. The orthogonal frequency set refers to the orthogonal relay radio station frequency set and the user radio station frequency set.

[0063] Step S300, uploading the message or voice to be transferred to the uplink shortwave relay station based on the uplink shortwave communication link, and the uplink shortwave relay station sends the message or voice to be transferred to the shortwave relay control subsystem.

[0064] Step S400, based on the shortwave forwarding control subsystem, a forwarding shortwave radio station that is currently out of service is selected as a downlink forwarding shortwave radio station, and the downlink forwarding shortwave radio station is controlled to establish a downlink shortwave communication link with a target shortwave user corresponding to the message or voice to be forwarded.

[0065] Step S500, sending the message or voice to be transferred to the target shortwave user via the downlink shortwave communication link, and obtaining a receipt fed back by the target shortwave user.

[0066] Step S600: Feedback the receiving receipt to the source shortwave user.

[0067] like Figure 7 and Figure 8 As shown, the service forwarding process of the present invention is described in detail by taking message forwarding as an example. The present invention includes the steps of communication parameter planning, uplink scanning call link establishment, uploading of messages to be forwarded, downlink scanning call link establishment, downlink forwarding of messages to be forwarded and forwarding result processing.

[0068] (1) Communication parameter planning.

[0069] Before the shortwave relay system operates normally, the system scale, site distribution, and communication parameters need to be planned through the shortwave relay control subsystem, including but not limited to the following parameter planning: shortwave communication terminal IP address, radio station address, communication frequency set, etc.

[0070] 1a) According to the number of concurrent shortwave users 2N, determine the number of shortwave relay stations and the number of shortwave radio stations they relay. Assuming the number of shortwave relay stations is N, to ensure that 2N shortwave users can communicate in both directions at the same time, the total number of shortwave radio stations corresponding to all shortwave relay stations is at least 2N, so each station should be equipped with at least 2 sets of full-duplex shortwave radio stations.

[0071] 1b) Based on the requirements of relay communication distance, shortwave blind area coverage, and the power level of the relay shortwave radio station, determine the geographical distribution plan of the system's N shortwave relay stations, and plan, transform or construct the sites according to the plan.

[0072] 1c) According to the relay communication distance, the number of the shortwave users, the number of the shortwave relay stations and the concurrent communication constraints, the communication frequency sets corresponding to the relay shortwave radio stations and the shortwave users are determined using the available frequency database.

[0073] 1d) Plan the shortwave communication parameters, including but not limited to the radio station address, the frequency set of the relay radio station and the frequency set of the user radio station. Note: The communication frequency set of each relay shortwave radio station and the communication frequency set of each shortwave user must be orthogonal, and the number of communication frequencies of the two must be equal; the local address of each relay shortwave radio station is uniformly planned to be the same address (for example, uniformly 100), and the local address of each shortwave user can be coded in sequence or in combination with the actual numbering requirements of the user.

[0074] 1e) After the shortwave communication parameter planning is completed, it can be sent to each shortwave radio station and shortwave user to complete the injection of the shortwave radio station communication parameters.

[0075] 1f) After the above preparations are completed, the transfer process will begin.

[0076] (2) Uplink scanning call link establishment.

[0077] 2a) Shortwave users include shortwave communication terminals and user shortwave radio stations. The relay shortwave radio stations corresponding to each shortwave relay station and the user shortwave radio stations corresponding to each shortwave user generally operate in a scanning state or a fixed-frequency reception standby state of the entire relay frequency set. Among them, the relay shortwave radio stations and user shortwave radio stations both have full-band reception capabilities.

[0078] 2b) Assuming that shortwave user 1 wants to forward a message or voice to shortwave user 2 through the shortwave relay communication control system, shortwave user 1 can control the user's shortwave radio to initiate a scanning call by operating the shortwave communication terminal, and the call address is 100.

[0079] 2c) The system communication parameters planned by the present invention can ensure that each shortwave user can call any channel in the frequency set F1 and can only call through one shortwave relay station and establish a shortwave communication link with it. Assuming that when shortwave user 1 sends a call protocol data unit (PDU) message or voice on the f11 channel, it is received by the relay shortwave radio station 1 of the shortwave relay station A in the A area of ​​the shortwave relay communication control system, then the relay shortwave radio station 1 will parse and judge the PDU message or voice. If the relay shortwave radio station 1 does not receive the call signal, or receives the call signal but cannot parse and judge whether to call address 100, the relay shortwave radio station 1 returns to the scanning or fixed frequency waiting state.

[0080] 2d) When the relaying shortwave radio station 1 determines that the address of the callee of shortwave user 1 is 100, and the caller (i.e. shortwave user 1) is a legitimate user, it immediately sends a response PDU message or voice on the same channel.

[0081] 2e) When shortwave user 1 receives the response PDU message or voice sent by the forwarded shortwave radio station 1, it analyzes and determines that the response PDU message or voice is a correct response, and immediately sends a confirmation PDU message or voice on the same channel, and enters the link establishment state after sending. If shortwave user 1 does not receive a response, it checks whether the current frequency set F1 has been scanned and called once. If so, the user shortwave radio of shortwave user 1 returns to the scanning or fixed frequency waiting state; if not, the user shortwave radio of shortwave user 1 continues to scan and call the remaining uncalled channels.

[0082] 2f) When the shortwave radio station 1 receives the confirmation PDU message or voice from the shortwave user 1, it enters the link establishment state; otherwise, it returns to the scanning or fixed-frequency waiting state.

[0083] 2g) When both the shortwave user 1 and the shortwave radio station 1 enter the link establishment state, it means that the two parties have established a shortwave wireless communication link and can carry out business communications.

[0084] (3) Messages or voice messages to be transferred are uploaded.

[0085] 3a) After shortwave user 1 establishes a link with the forwarding shortwave radio station 1, it means that shortwave user 1 can send messages or voices to be forwarded. Shortwave user 1 needs to initiate a forwarding service request first and send a forwarding request PDU message or voice to the forwarding shortwave radio station 1.

[0086] 3b) If the forwarding shortwave radio station 1 receives a forwarding request PDU message or voice, it sends a forwarding permission PDU message or voice on the same channel. After sending, it enters the link establishment state and waits for receiving messages or voice. If the forwarding shortwave radio station 1 does not receive a forwarding request PDU message or voice, it returns to the link establishment state.

[0087] 3c) When shortwave user 1 receives the PDU message or voice message allowed to be forwarded, it starts uploading the message or voice data to be forwarded; the forwarding shortwave radio station 1 starts receiving the message or voice baseband signal and sends the baseband signal to the shortwave forwarding system for demodulation.

[0088] 3d) When the forwarding shortwave radio station 1 successfully receives the message or voice, the shortwave forwarding control subsystem obtains the destination user address of the downlink forwarding through the forwarding route in the message or voice (assuming that the destination user is shortwave user 2), and selects the forwarding shortwave radio station that is currently out of service (assuming that the system selects the forwarding shortwave radio station 6) to forward the downlink message or voice to be forwarded.

[0089] (4) Downlink scan call link establishment.

[0090] Before downlink forwarding, the shortwave forwarding control subsystem needs to control the forwarding shortwave radio station 6 to establish a wireless communication link with the destination shortwave user 2. The specific process is basically the same as the uplink scanning call link establishment process, which will not be repeated here.

[0091] (5) Forwarding of messages or voice calls to be forwarded.

[0092] 5a) After the signal-relaying shortwave radio station 6 successfully establishes a link with the shortwave user 2, the shortwave signal-relaying control subsystem controls the signal-relaying shortwave radio station 6 to send the message or voice to be transferred to the shortwave user 2.

[0093] 5b) If shortwave user 2 receives and demodulates the message or voice successfully, it reports a "forwarding success" receipt PDU message or voice to the shortwave forwarding control subsystem; if the reception fails, it reports a "forwarding failure" receipt PDU message or voice. After sending the forwarding receipt, shortwave user 2 returns to the link establishment state.

[0094] (6) Forwarding result processing.

[0095] 6a) After receiving the forwarding result (forwarding success or forwarding failure) reported by the shortwave user 2, the shortwave forwarding radio station 6 forwards it to the shortwave forwarding control subsystem.

[0096] 6b) The shortwave signal relay control subsystem feeds back to the shortwave user 1 the downlink forwarding status of the signal relay from the shortwave signal relay station and the forwarding result reported by the shortwave user 2, the final recipient of the message or voice.

[0097] 6c) After the shortwave user 1 receives and demodulates the forwarding result PDU message or voice, it is presented on the visual interface of the shortwave communication terminal.
