Description

Technical Field

[0001] This invention relates to the field of electromagnetic spectrum management technology, specifically to a method and system for on-the-spot decision-making regarding frequency usage when frequency usage service channels are damaged. Background Technology

[0002] In wireless communication systems, different frequency-using devices typically operate within their respective frequency bands according to a predetermined frequency allocation scheme. When some frequency-using devices malfunction, service channels are damaged, or temporary replacements are needed, the replacement devices may overlap with the existing frequency-using devices in the operating frequency band, thus affecting the existing frequency allocation and communication services.

[0003] In existing technologies, when the above-mentioned situations occur, it is usually necessary to reconfigure the available frequency points of the relevant equipment. Due to differences in factors such as transmit power, antenna gain, distance between devices, receiver sensitivity, and frequency spacing, different combinations of frequency points may generate varying degrees of spectral interference. Improper frequency allocation may lead to a decrease in the receiving performance of some devices, affecting the continuity of communication services.

[0004] Therefore, how to coordinate and allocate frequency points for relevant frequency-using equipment in scenarios where frequency service channels are damaged and replacement equipment is introduced, so as to take into account both the temporary access needs of replacement equipment and the stable operation of existing services, remains a technical problem that needs to be solved. Summary of the Invention

[0005] The main objective of this invention is to provide a method and system for on-the-spot frequency decision-making when the frequency service channel is damaged, so as to achieve frequency point coordination and allocation of relevant frequency-using equipment while keeping the current operating frequency of the existing frequency-using equipment unchanged when the replacement equipment is connected.

[0006] The present invention achieves the above objectives through the following technical solutions: In a first aspect, the present invention provides a method for on-the-spot decision-making regarding frequency usage when a frequency usage service channel is damaged, the method comprising: The system acquires the operating frequency set and current operating frequency point of each of multiple existing frequency-using devices, as well as the operating frequency set of replacement devices for replacing damaged frequency-using devices, wherein the operating frequency set includes multiple frequency points corresponding to the operating frequency band of the frequency-using devices; Based on the overlap between the operating frequency band of the replacement device and the operating frequency bands of the plurality of existing frequency-using devices, the affected device is determined from the plurality of existing frequency-using devices; Based on the electromagnetic parameters of the replacement device and each of the affected devices, the distance between the devices, and their respective operating frequency sets, the spectral compatibility relationship between the frequency points of the replacement device and each of the affected devices is determined. The current operating frequency of each of the affected devices is pre-determined as the allocated frequency of the corresponding affected device; According to the preset device allocation order, the frequency-using device to be allocated is determined sequentially from the replacement device and each of the affected devices; for the frequency-using device to be allocated, the operating frequency set of the frequency-using device to be allocated is traversed to other frequency points besides the already allocated frequency points, and frequency points that satisfy the spectrum compatibility relationship with the frequency points already allocated to other frequency-using devices are selected from the traversed frequency points, and the selected frequency points are allocated to the frequency-using device to be allocated, so as to allocate frequency points to the replacement device and each of the affected devices while keeping the current operating frequency points of each of the affected devices unchanged; Based on the frequency points allocated to the replacement device and each of the affected devices, the frequency allocation result under the temporary access state of the replacement device replacing the damaged frequency-using device is determined.

[0007] Furthermore, existing frequency-using devices whose operating frequency bands overlap with those of the replacement device are identified as the affected devices, while the original frequency allocation schemes of existing frequency-using devices whose operating frequency bands do not overlap with those of the replacement device remain unchanged.

[0008] Further, determining the spectral compatibility relationship between the frequency points of the replacement device and each of the affected devices includes: For the first frequency point of the first frequency-using device and the second frequency point of the second frequency-using device, calculate the first interference power formed when the first frequency-using device transmits at the first frequency point and the second frequency-using device receives at the second frequency point, and compare the first interference power with the sensitivity level of the second frequency-using device; Calculate the second interference power formed when the second frequency-using device transmits at the second frequency point and the first frequency-using device receives at the first frequency point, and compare the second interference power with the sensitivity level of the first frequency-using device; If the first interference power does not exceed the sensitivity level of the second frequency-using device, and the second interference power does not exceed the sensitivity level of the first frequency-using device, then the first frequency point and the second frequency point are determined to satisfy the spectrum compatibility relationship; otherwise, the first frequency point and the second frequency point are determined not to satisfy the spectrum compatibility relationship.

[0009] Furthermore, the first interference power and the second interference power are determined based on the transmission power of the corresponding transmitting device, the antenna gain of the corresponding transmitting device in the direction of the receiving device, the receiving antenna gain of the corresponding receiving device, the distance between the first frequency-using device and the second frequency-using device, the receiving frequency, and the sideband suppression of the transmission frequency relative to the receiving frequency.

[0010] Further, determining the spectral compatibility relationship between the frequency points of the replacement device and each of the affected devices includes: The operating frequencies of the second frequency-using devices are arranged in ascending order of frequency. When the first frequency point of the first frequency-using device is greater than all the frequency points of the second frequency-using device, starting from the maximum frequency point of the second frequency-using device, the spectral compatibility relationship between the first frequency point and the frequency points of the second frequency-using device is calculated sequentially in the direction of frequency decrease, until the first boundary frequency point that satisfies the spectral compatibility relationship with the first frequency point is determined, and the first boundary frequency point and frequency points with frequencies lower than the first boundary frequency point are determined to satisfy the spectral compatibility relationship with the first frequency point. When the first frequency point is less than all the frequency points of the second frequency-using device, starting from the minimum frequency point of the second frequency-using device, the spectrum compatibility relationship is calculated sequentially in the direction of frequency increase until a second boundary frequency point that satisfies the spectrum compatibility relationship with the first frequency point is determined, and the second boundary frequency point and frequency points with frequencies higher than the second boundary frequency point are determined to satisfy the spectrum compatibility relationship with the first frequency point. When the first frequency point is located between the frequency points of the operating frequency set of the second frequency-using device, the spectral compatibility relationship between the first frequency point and the frequency point of the second frequency-using device is calculated sequentially along the frequency decreasing direction and the frequency increasing direction, respectively, to determine the third boundary frequency point and the fourth boundary frequency point that satisfy the spectral compatibility relationship with the first frequency point; and the third boundary frequency point, as well as the frequency points with frequencies lower than the third boundary frequency point, the fourth boundary frequency point, and the frequency points with frequencies higher than the fourth boundary frequency point are determined to satisfy the spectral compatibility relationship with the first frequency point.

[0011] Furthermore, the spectrum compatibility relationship is represented by an interference matrix, where the matrix elements indicate whether there is spectrum interference between the frequency points of the corresponding two frequency-using devices.

[0012] Further, the allocation of frequency points for the replacement device and each of the affected devices includes: For the frequency-using equipment currently to be allocated, according to the order of each frequency point in the working frequency set of the frequency-using equipment, traverse the other frequency points except for the already allocated frequency points in turn, and determine whether the frequency point currently traversed satisfies the spectrum compatibility relationship with the frequency points already allocated to other frequency-using equipment. If the frequency point being traversed satisfies the spectrum compatibility relationship with all the frequency points already allocated to other frequency-using devices, the frequency point being traversed will be allocated to the frequency-using device to be allocated. If the frequency point being traversed does not satisfy the spectrum compatibility relationship with any of the frequency points already allocated to other frequency-using devices, skip the frequency point being traversed and continue traversing the next frequency point in the operating frequency set of the frequency-using devices to be allocated.

[0013] Furthermore, for the frequency-using device currently to be allocated, the operating frequency of the frequency-using device is traversed through the other frequency points besides the already allocated frequency points until all the other frequency points have been traversed, or the traversal stops when the number of frequency points allocated to the current frequency-using device reaches a preset target number.

[0014] Furthermore, the preset device allocation order is determined according to the device allocation priority, with the replacement device having the highest device allocation priority, and the affected devices are arranged in descending order of device importance; In each round of frequency allocation, a frequency point is allocated to the replacement device and each of the affected devices in sequence according to the preset device allocation order, and after each round of frequency allocation is completed, the next round of frequency allocation is carried out according to the preset device allocation order.

[0015] Secondly, the present invention provides a frequency usage on-the-spot decision-making system under the condition of damaged frequency service channels, including a device information acquisition module, an affected device determination module, a spectrum compatibility relationship determination module, a current working frequency pre-allocation module, a frequency allocation module, and a frequency allocation result determination module; each module is used to execute the above-mentioned frequency usage on-the-spot decision-making method under the condition of damaged frequency service channels.

[0016] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects: The present invention provides a method and system for on-the-spot frequency allocation decision-making under the condition of damaged frequency service channels. This method identifies affected equipment based on the overlap of operating frequency bands between replacement equipment and existing frequency-using equipment, and pre-reserves the current operating frequency of each affected device. It determines the spectral compatibility relationship between each frequency point based on the device's electromagnetic parameters, the distance between devices, and the set of operating frequencies. Frequency points are then allocated to the replacement equipment and affected equipment according to a preset equipment allocation order. Therefore, in the case of temporary access by replacement equipment, the impact on the original frequency allocation scheme of unrelated frequency-using equipment is reduced. Furthermore, while maintaining the current operating frequency of the affected equipment, a frequency allocation result that satisfies the spectral compatibility relationship is determined, thereby helping to ensure the continuity of frequency services and improve the efficiency of frequency adjustment.

[0022] When a frequency-using device in a frequency-using service channel is damaged, a replacement device with the same service function can be used to ensure the overall functionality of the channel. In this case, the replacement device needs to be assigned a frequency point within a specific operating frequency range, ensuring spectral compatibility with other current frequency-using devices. Simultaneously, the operating frequency set of the current frequency-using devices needs to be adjusted, without changing their current operating frequencies, thereby improving frequency adjustment efficiency.

[0023] like Figure 1 As shown, this invention addresses the need for on-the-spot frequency decision-making when a frequency-using service channel is damaged. It proposes a method for allocating frequency sets for replacement equipment and an adjustment method for allocating frequency sets for existing frequency-using equipment. The method involves determining the affected frequency-using equipment after the replacement equipment is connected, calculating the spectral compatibility between candidate frequency points, and implementing frequency point coordination allocation based on pre-reserved current operating frequency points. This forms a frequency adjustment scheme for the temporary access state of the replacement equipment, including the following steps: Step 1: Obtain information about the damaged frequency-using equipment and its replacement equipment, including the name of the damaged frequency-using equipment and the name of the replacement equipment. By accessing the database based on the equipment name, data such as the electromagnetic parameters and operating frequency set of the equipment can be obtained.

[0024] Step 2: Group all frequency-using devices, including replacement devices, according to frequency bands. When the frequency of a device changes, it will affect the spectrum usage of devices in the same group. However, because the operating frequency sets of devices in different groups are far apart, there is no spectrum interference between devices in different groups.

[0025] This step groups all frequency-using devices, including replacement devices, according to their operating frequency bands. When the operating frequency of a particular device changes, it primarily affects the spectrum usage of devices within the same group. For different groups whose operating frequency sets are far apart and whose spectrum compatibility determines there is no mutual interference, their original frequency allocation schemes can remain unchanged. This reduces the scope of devices involved in on-the-spot adjustments and minimizes disruption to existing frequency-using services.

[0026] Step 3: Perform spectrum interference calculation on the frequency-using equipment in the group where the replacement equipment is located, and obtain the electromagnetic interference matrix. The calculation method uses the electromagnetic interference equation.

[0027] For example, the distance between device A and device B is R. Device A's operating frequency set includes 10 frequency points, and device B's operating frequency set includes 15 frequency points. When traversing the frequency points of device A, the spectral interference between the first frequency point A1 of device A and each frequency point of device B is first calculated. The position of frequency point A1 relative to the operating frequency set of device B can be divided into the following three cases: Scenario 1: A1 is greater than all operating frequencies of device B. In this case, we first calculate whether there is a spectral conflict between the maximum frequency B15 of device B and A1. The calculation method is as follows: (1) Calculate the radiated power density S at device B when device A emits at frequency A1: ; Among them, P A For the transmission power of A, G A Let A be the antenna gain in the direction of B.

[0028] Interference power P received by the antenna of the sensitive device r for: ; In the formula, A r The effective receiving area of ​​the receiving antenna of device B can be expressed as: ; In the formula, λ r For device B to receive wavelength, G B Let λ be the gain of the receiving antenna of device B, where λ is the gain of the receiving antenna of device B. r Represented as: ; In the formula, c is the speed of light.

[0029] If device A transmits at frequency A1 and device B receives at frequency B15, and the sideband suppression is L, then the interference power at the receiving frequency is: ; The sensitivity level of device B is S. B If P r >S B If device A transmits at frequency A1 and device B receives at frequency B15, then there will be spectral interference between them; otherwise, there will be no spectral interference.

[0030] (2) Calculate the spectral interference when device B transmits and device A receives, as follows: The radiated power density S at device A when device B emits is: ; Among them, P B For the transmission power of B, G B Let B be the antenna gain in the direction of A.

[0031] Interference power P received by the antenna of the sensitive device r for: ; In the formula, A r The effective receiving area of ​​the receiving antenna of device A can be expressed as: ; In the formula, λ r For device A to receive wavelength, G A Let λ be the gain of the receiving antenna of device A, where λ is the gain of the receiving antenna of device A. r Represented as: ; In the formula, c is the speed of light.

[0032] Device B transmits at frequency B15, and the sideband suppression of device A at frequency A1 is L. Then the interference power at the received frequency is: ; The sensitivity level of device A is S. A If P r >S A If device A receives at A1 and device B transmits at B15, then there will be spectral interference between them; otherwise, there will be no spectral interference.

[0033] (3) When the calculation results of the above two directions indicate that there is no spectrum interference, it is determined that there is no spectrum interference when device A works at frequency point A1 and device B works at frequency point B15; otherwise, it is determined that there is spectrum interference between the two.

[0034] (4) If there is no spectral interference between A1 and B15, then there is no spectral interference between A1 and all frequency points of device B; if there is spectral interference between A1 and B15, then calculate the spectral interference between A1 and the previous frequency point of B15 until the nearest non-interfering frequency point is found. In this way, the spectral interference characteristics between A1 and all frequency points of device B are obtained.

[0035] The second scenario: A1 is less than all operating frequencies of device B. In this case, start the calculation from frequency point B1 and determine the nearest interference-free frequency point to A1.

[0036] The third scenario: If A1 is between the frequency points of device B, then find the nearest interference-free frequency point on both sides.

[0037] By following the steps above, the interference characteristics between frequency point A1 and each frequency point of device B can be determined. By traversing each frequency point of device A in the same way, the spectral interference relationship between each frequency point of each frequency-using device in the group can be determined.

[0038] The judgment results of the above frequency point combinations are written into the interference matrix. The matrix elements in the interference matrix are used to characterize whether there is spectral interference between the candidate frequency points of the corresponding two frequency-using devices. When allocating frequency points in the future, the interference matrix can be directly queried to determine whether the current candidate frequency point and the allocated frequency point meet the spectral compatibility relationship, thereby avoiding repeated interference power calculations.

[0039] Step 4: Allocate frequencies based on the spectrum interference calculation results.

[0040] First, the current operating frequency of each undamaged but affected frequency-using device is pre-determined as its assigned frequency to ensure that the current operating frequency does not need to be adjusted. Then, the allocation priority of frequency-using devices within the group is set, with replacement devices having the highest priority, and other devices ranked according to importance. The highest-priority device undergoes the first round of frequency allocation, starting with the smallest allocable frequency. If the frequency does not interfere with any previously allocated frequency, it is allocated; if it interferes with any previously allocated frequency, it is not allocated. The process moves to the next frequency until an interference-free frequency is found. This completes the frequency allocation for that device in this round. The same method is then used to allocate frequencies to the next device. After the first round of allocation, the next round of frequency allocation is performed according to priority until all devices have all their frequencies allocated.

[0041] The above methods form a frequency adjustment scheme for the group containing the replacement equipment. This scheme calculates the spectral interference characteristics after the introduction of the replacement equipment, obtains the interference frequency pairs and interference matrix, and sets the allocation priority for all frequency-using equipment in the group, including the replacement equipment. Based on the changes in the interference pairs after the introduction of the replacement equipment, a frequency adjustment scheme is obtained. The current operating frequency of other frequency-using equipment besides the replacement equipment remains unchanged, thus improving the efficiency of frequency adjustment.

[0042] In another embodiment of the present invention, the on-the-spot decision-making method for frequency usage under the condition of frequency usage service channel impairment includes the following steps: There are five frequency-using devices: Device A, Device B, Device C, Device D, and Device E. Devices A, B, and C are of the same model, each operating on 30 frequencies from F1 to F30. Devices D and E are of the same model operating on a different frequency band, each operating on 20 frequencies from E1 to E20. Device A's frequency allocation scheme is F3, F12, F22, with its current operating frequency at F3; Device B's is F1, F9, F19, F28, with its current operating frequency at F1; Device C's is F6, F16, F25, with its current operating frequency at F6; Device D's is E1, E7, E14, with its current operating frequency at E7; and Device E's is E4, E10, E18, with its current operating frequency at E18. Assuming equipment E is damaged, and equipment F is used to replace it, and equipment F is the same model as equipment A and equipment B, the on-site adjustment method is as follows: Step 1: Group the frequency-using devices according to frequency bands. Devices A, B, and F are in one group, while devices C and D are in another. The damage to device E will not affect the spectrum usage of devices C and D; therefore, no temporary frequency adjustments are needed for devices C and D. Only the frequency usage schemes for devices A and B need to be adjusted, and a working frequency set needs to be allocated to device F.

[0043] Step 2: First, perform spectrum interference calculations for devices A, B, and F in the same group, and then perform interference calculations for each frequency combination of any two devices.

[0044] Taking devices A and B as examples, the distance between them is R, and the operating frequency sets of both devices A and B include 30 frequency points. When traversing each frequency point of device A, the spectral interference between the first frequency point F1 of device A and each frequency point of device B is first calculated. The calculation method is as follows: (1) Calculate the radiated power density S at point B when A emits at frequency F1: ; Among them, P ALet G be the transmission power of A. A Let A be the antenna gain in the direction of B.

[0045] Interference power P received by the antenna of the sensitive device r for: ; In the formula, A r The effective receiving area of ​​the receiving antenna of device B can be expressed as: ; In the formula, λ r For the wavelength received by device B, G B Let λ be the gain of the receiving antenna of device B, where λ is the gain of the receiving antenna of device B. r Represented as: ; In the formula, c is the speed of light.

[0046] If device A transmits at frequency F1 and device B receives at frequency F2 with a sideband suppression of L, then the interference power at the receiving frequency is: ; In the formula, the sensitivity level of device B is S. B If P r >S B If device A transmits at F1 and device B receives at F2, then there will be spectral interference between them; otherwise, there will be no spectral interference.

[0047] (2) Calculate the spectral interference when device B transmits and device A receives, as follows: The radiation power density S at point A when B is emitted is calculated as follows: ; Among them, P B For the transmission power of B, G B Let B be the antenna gain in the direction of A.

[0048] Interference power P received by the antenna of the sensitive device r for: ; In the formula, A r The effective receiving area of ​​the receiving antenna of device A can be expressed as: ; In the formula, λ r For the wavelength received by device A, G A Let λ be the gain of the receiving antenna of device A, where λ is the gain of the receiving antenna of device A. r Represented as: ; c is the speed of light.

[0049] If device B transmits at frequency F2 and device A has a sideband suppression of L at frequency F1, then the interference power at the received frequency is: ; The sensitivity level of device A is S. A If P r >S A If device A receives at F1 and device B transmits at F2, then there will be spectral interference between them; otherwise, there will be no spectral interference.

[0050] (3) When the calculation results of the above two directions indicate that there is no spectrum interference, it is determined that there is no spectrum interference when device A works at frequency point F1 and device B works at frequency point F2; otherwise, it is determined that there is spectrum interference between the two.

[0051] (4) If there is no spectral interference between F1 and F2, then there is no spectral interference between F1 and all frequency points of device B; if there is spectral interference between F1 and F2, then continue to calculate the spectral interference between F1 and subsequent frequency points of device B until the nearest interference-free frequency point is found. Thus, the spectral interference characteristics between F1 and each frequency point of device B are obtained.

[0052] By following the steps above, the interference characteristics between frequency point F1 and each frequency point of device B can be determined. By traversing each frequency point of device A in the same way, the spectral interference relationship between each frequency point of each frequency-using device in the group can be determined.

[0053] Step 3: Allocate frequencies based on the spectrum interference calculation results.

[0054] First, the current operating frequencies F3 and F1 of devices A and B are pre-assigned to their respective devices to ensure that the current operating frequencies do not change. Device F is assigned the highest priority. Devices A and B are sorted according to a predetermined priority. Assuming that the priority of device B is higher than that of device A, the assignment order is device F, device B, and device A.

[0055] Frequency allocation is adjusted in the above order. The highest priority device is allocated frequency first, starting with the smallest allocable frequency, F2. Since F2 conflicts with the already allocated frequency F1, it cannot be allocated. The process continues sequentially until F10 becomes allocable, thus completing the first round of allocation for device F. Then, frequency points are allocated to device B, with its nearest allocable frequency being F14. Allocation continues in the same way, resulting in the following frequency adjustment scheme: Device A: F3, F17, F30; Device B: F1, F14, F28; Device F: F10, F24.

[0056] As shown in the above allocation results, the current operating frequencies F3 and F1 of devices A and B remain unchanged; device F obtains frequencies F10 and F24, enabling it to replace the damaged device E. Devices C and D, since they do not belong to the same affected frequency band group as device F, retain their original frequency allocation schemes. Thus, under the condition of satisfying spectrum compatibility, a minimum range of frequency adjustment for the damaged service channel is achieved.

[0057] Step 4: The above method forms a frequency usage adjustment plan. This plan recalculates the interference based on the distance between the replacement equipment and the current frequency-using equipment, assigns a working frequency set to the replacement equipment, adjusts the assigned frequency set of the current working equipment, and does not change the current working frequency of the current working equipment, thus achieving minimal frequency usage adjustment and ensuring adjustment efficiency.

[0058] like Figure 2 As shown, the present invention also provides a frequency allocation on-the-spot decision-making system for performing the above-described method. The system includes a device information acquisition module, an affected device determination module, a spectrum compatibility determination module, a current operating frequency pre-allocation module, a frequency allocation module, and a frequency allocation result determination module.

[0059] The equipment information acquisition module acquires the operating frequency sets and current operating frequencies of multiple existing frequency-using devices, as well as the operating frequency set of replacement devices. The affected equipment determination module identifies the affected devices based on the overlap of operating frequency bands between the replacement devices and each existing frequency-using device. The spectrum compatibility determination module determines the spectrum compatibility between candidate frequency points based on the electromagnetic parameters, distances between devices, and operating frequency sets of the replacement and affected devices. The current operating frequency pre-allocation module pre-determines the current operating frequency of each affected device as an allocated frequency point.

[0060] The frequency allocation module determines the frequency-using equipment to be allocated according to a preset equipment allocation order, and selects a frequency point from the candidate frequency points within the operating frequency set of that equipment that meets the spectrum compatibility relationship with other allocated frequency points. The frequency allocation result determination module determines the frequency allocation result of the replacement equipment under temporary access status based on the allocated frequency points of the replacement equipment and each affected equipment. The above modules can collaboratively complete the on-the-spot decision-making process when the frequency service channel is damaged through data interaction.

[0061] In a specific implementation, the system may include a memory, a processor, and a computer program stored in the memory. When the processor executes the computer program, it can perform the steps described above: acquiring device information, identifying affected devices, establishing spectrum compatibility relationships, pre-allocating current operating frequencies, performing frequency allocation, and determining the frequency allocation result. The computer program may also be stored in a computer-readable storage medium and implement the above methods when executed by the processor.

[0062] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. For those skilled in the art, any equivalent substitutions, combinations or modifications made to the above embodiments without departing from the technical concept of the present invention should fall within the protection scope of the present invention.
