[0002] IP Multimedia Subsystem (IMS) is a new form of multimedia service, and satellite-to-ground IMS interoperability is a core component of the integrated space-ground information network. Its core requirement is to achieve seamless integration between satellite terminals and terrestrial communication networks, enabling communication across the entire network. Among these requirements, the precise matching of the simulated access location of the satellite terminal with the base station providing terrestrial communication is a key technology for ensuring the quality of satellite-to-ground calls.

[0003] Currently, existing analog access location matching algorithms have some technical drawbacks. For example, existing algorithms generally use a circular coverage model, calculating the coverage area based solely on the base station's transmission power and ideal propagation conditions, which leads to the problem of mismatched base stations. Furthermore, matching decisions are made based solely on the distance between the satellite terminal and the ground base station, resulting in low service availability of the matched base station, which may cause call interruptions due to excessive base station load or poor signal quality.

[0015] Example 1 Figure 1 This is a flowchart of a base station determination method according to Embodiment 1 of the present invention. This embodiment is applicable to the determination of a target base station. The method can be executed by a base station determination device, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes: S110. Determine the satellite terminal to be matched, and the original base station set corresponding to the satellite terminal to be matched.

[0016] The original base station set includes at least one original base station, and the satellite terminal to be matched is within the coverage area of ​​each of the original base stations.

[0017] In this embodiment, the satellite terminal to be matched can be understood as a satellite terminal, which can be a device used to establish a communication link with a satellite. The original base station set can be understood as a set consisting of at least one original base station, and the satellite terminal to be matched is a terminal within the coverage area of ​​the original base station.

[0018] Specifically, among the ground base stations in each region, at least one original base station is selected to form an original base station set. The method for selecting the original base station can be as follows: search among the ground base stations in each region, and for each ground base station, determine whether the satellite terminal to be matched is within the effective coverage area of ​​the original base station. If so, then the ground base station is selected as the original base station.

[0019] S120. Based on the first base station operating parameter data corresponding to each original base station in the original base station set, at least one candidate base station is selected from the original base station set.

[0020] The candidate base station includes the original base station that matches the satellite terminal to be matched. The first base station's engineering parameter data includes the parameters of the original base station and information on simulated communication between the original base station and the satellite terminal to be matched.

[0021] In this embodiment, the first base station operating parameter data can be understood as the base station operating parameter data corresponding to the original base station. The first base station operating parameter data can be formed by the parameters of the original base station and the information during simulated communication between the original base station and the satellite terminal to be matched. The parameters of the original base station can include the parameters of the original base station itself. The candidate base station can be understood as the original base station selected from the set of original base stations that matches the satellite terminal to be matched.

[0022] Specifically, for each original base station in the original base station set, the first base station operating parameter data corresponding to the original base station is first determined. The first base station operating parameter data may include the original base station's signal strength, altitude, transmission power, scene, signal coverage direction, etc., as well as the distance between the original base station and the satellite terminal to be matched when simulating communication between the original base station and the satellite terminal to be matched. Based on the first base station operating parameter data corresponding to each original base station, the matching degree between each original base station and the satellite terminal to be matched is determined, and at least one original base station with a high matching degree is identified as a candidate base station.

[0023] For example, the first base station's operating parameter data may include the following types of parameters: first signal strength. : Directly reflects the communication quality between the satellite terminal to be matched and the original base station; distance between the terminal and the base station : Represents the straight-line distance between the satellite terminal to be matched and the original base station, calculated from the latitude and longitude of the original base station and the positioning coordinates of the satellite terminal to be matched, and is the core factor affecting signal attenuation; Antenna azimuth angle : Taken from the base station engineering parameter library, reflecting the degree of fit between the signal coverage direction of the original base station and the location of the satellite terminal to be matched; occlusion confidence level : Quantifies the severity of obstruction between the satellite terminal to be matched and the original base station, with a value ranging from 0 to 1. The closer it is to 1, the more severe the occlusion.

[0024] S130. Based on the candidate base station scores corresponding to each candidate base station, select the target base station from among the candidate base stations.

[0025] The candidate base station score is related to the second base station operating parameter data corresponding to the candidate base station. The candidate base station score indicates the communication status between the candidate base station and the satellite terminal to be matched. The target base station includes the base station that the satellite terminal to be matched simulates accessing.

[0026] In this embodiment, the candidate base station score can be understood as the scoring result of the candidate base station, and the candidate base station score can be understood as the quantitative score of the candidate base station. The second base station operating parameter data can be understood as the base station operating parameter data corresponding to the candidate base station, and the second base station operating parameter data can be formed by the parameters of the candidate base station and the information of the simulated communication between the candidate base station and the satellite terminal to be matched. The parameters of the candidate base station can include the parameters of the candidate base station itself. The target base station can be understood as the candidate base station selected from at least one candidate base station, and the target base station is the best access base station for the satellite terminal to be matched.

[0027] Specifically, for each candidate base station, the operating parameters of the corresponding second base station are first determined. These parameters may include the candidate base station's signal strength, matching stability, base station load, and channel quality during simulated communication between the candidate base station and the satellite terminal to be matched. Based on the operating parameters of the second base station for each candidate base station, a candidate base station score is determined. The candidate base station with the highest score is then identified as the target base station.

[0028] For example, the operating parameters data of the second base station may include the following types of parameters: signal strength. Values ​​ranging from ≥-120dBm directly reflect the communication quality between the satellite terminal to be matched and the candidate base station; channel quality. : Reflects the signal's anti-interference capability, taken from actual measured data at the terminal, with a value range of 0~30dB; Matching stability The historical matching success rate of terminals other than the satellite terminal to be matched (mobile phones or communication terminals) with the candidate base station, with a value ranging from 0 to 1 (i.e., 0% to 100%); base station load. The percentage of terminals connected to the candidate base station, ranging from 0 to 1 (i.e., 0% to 100%). The lower the load, the more guaranteed the communication quality.

[0029] The technical solution of this invention involves determining a satellite terminal to be matched and the original set of base stations corresponding to the satellite terminal; selecting at least one candidate base station from the original base station set based on the first base station engineering parameter data corresponding to each original base station; and selecting a target base station from among the candidate base stations based on the candidate base station scores corresponding to each candidate base station. By selecting at least one candidate base station from the original base station set using the first base station engineering parameter data, the selection of base stations is achieved through multiple types of parameters. Furthermore, by selecting the target base station from among the candidate base stations using the second base station engineering parameter data, multiple screenings of the target base station are implemented, improving the efficiency and accuracy of base station matching.

[0030] Based on the above embodiments, modified embodiments of the above embodiments are proposed. It should be noted that, in order to keep the description brief, only the differences from the above embodiments are described in the modified embodiments.

[0031] In one embodiment, selecting at least one candidate base station from the original base station set based on the first base station operating parameter data corresponding to each original base station in the original base station set includes: For each original base station in the original base station set, determine the first base station operating parameter data corresponding to the original base station, and determine the comprehensive membership degree corresponding to the original base station based on the first base station operating parameter data. The comprehensive membership degree indicates the degree of matching between the original base station and the satellite terminal to be matched. Among the comprehensive membership degrees, at least one original base station corresponding to the comprehensive membership degree that satisfies the membership degree condition is determined as at least one candidate base station, wherein the membership degree condition is related to the value of each comprehensive membership degree.

[0032] In this embodiment, the comprehensive membership degree can be understood as a numerical value indicating the degree of matching between the original base station and the satellite terminal to be matched. The larger the comprehensive membership degree value, the higher the degree of matching between the original base station and the satellite terminal to be matched. The membership degree condition can be a condition used to select candidate base stations, and a set number of comprehensive membership degrees with the highest comprehensive membership degree values ​​can be selected.

[0033] Specifically, for each original base station in the original base station set, the comprehensive membership degree corresponding to the original base station is calculated based on the first base station's operating parameter data. Then, at least one original base station corresponding to a comprehensive membership degree that satisfies the membership condition is identified as at least one candidate base station. Specifically, this can be done by sorting the comprehensive membership degrees according to their numerical values ​​and identifying the original base stations corresponding to a predetermined number of comprehensive membership degrees as candidate base stations.

[0034] For example, the membership condition could be: selecting a comprehensive membership degree from the original base station set. The top 3 original base stations were selected as candidate base stations.

[0035] Optionally, determining the comprehensive membership degree corresponding to the original base station based on the first base station's engineering parameter data includes: In the first base station engineering parameter data, at least one base station evaluation index corresponding to the original base station is selected. The at least one base station evaluation index includes a first signal strength, the distance between the terminal and the base station, the antenna azimuth angle, and the obstruction confidence. The first signal strength indicates the communication quality of the original base station. The distance between the terminal and the base station includes the straight-line distance between the satellite terminal to be matched and the original base station. The antenna azimuth angle indicates the degree of fit between the coverage direction of the signal transmitted by the original base station and the location of the satellite terminal to be matched. The obstruction confidence includes the degree of obstruction between the satellite terminal to be matched and the original base station. The evaluation indicators of each base station are quantified to generate a membership value corresponding to each base station evaluation indicator. Each membership value indicates the degree of matching between the original base station and the satellite terminal to be matched, as indicated by each base station evaluation indicator. Based on the scenario where the original base station is located, determine the weight of each base station evaluation indicator; Based on each membership value and its corresponding index weight, the comprehensive membership degree corresponding to the original base station is determined.

[0036] In this embodiment, the base station evaluation index can be understood as an index used to calculate the comprehensive membership degree. The base station evaluation index can be an index selected from the first base station operating parameter data, including the first signal strength of the original base station, the distance between the terminal and the base station, the antenna azimuth angle, and the obstruction confidence level. The first signal strength indicates the communication quality of the original base station. The distance between the terminal and the base station includes the straight-line distance between the satellite terminal to be matched and the original base station, calculated from the latitude and longitude of the original base station and the positioning coordinates of the satellite terminal to be matched. The antenna azimuth angle indicates the degree of fit between the coverage direction of the signal transmitted by the original base station and the location of the satellite terminal to be matched, taken from the base station operating parameter library. The obstruction confidence level includes the degree of obstruction between the satellite terminal to be matched and the original base station, i.e., the quantified severity of obstruction between the satellite terminal to be matched and the original base station. The index weight can be understood as the weight determined for each base station evaluation index based on the scenario where the original base station is located. The index weights can be constructed using the analytic hierarchy process (AHP).

[0037] For example, at least one base station evaluation index corresponding to the original base station is selected from the first base station operating parameter data, including: first signal strength. Distance between terminal and base station Antenna azimuth angle and occlusion confidence The evaluation indicators for each base station are quantified, generating membership values ​​corresponding to each indicator. Specifically, this can be achieved by constructing a membership function to quantify each base station evaluation indicator into a membership value within the range [0,1]. This includes: the first signal strength... The membership value corresponding to the trapezoidal membership function is Distance between terminal and base station The membership value corresponding to the (inverse trapezoidal membership function) is Where 3km is a reference value for the typical outdoor coverage radius of a 4G base station. Antenna azimuth angle. The membership value corresponding to the (triangle membership function) is ,in, The azimuth angle of the line connecting the satellite terminal to be matched and the original base station is 60°, which is the typical half-angle of coverage for a 4G macro base station antenna. (Obstruction confidence level) The membership value corresponding to the (inverse trapezoidal membership function) is Weight vectors can be established using the Analytic Hierarchy Process (AHP). Where: first signal strength Weight 0.4 (core indicator, prioritizing communication quality); distance between terminal and base station Weight 0.25; Antenna azimuth angle Weight 0.15; Occlusion confidence Weight 0.2; Weight vector After consistency test ( Next, based on the original base station's location, the weights of each base station's evaluation metrics can be adjusted. For example, in an urban area (dense high-rise buildings): the adjusted weight vector... (Improve occlusion confidence) Weight to 0.25, reduce distance Weights adjusted to 0.2); Mountainous scenes (severe vegetation obstruction, large terrain undulations): Adjusted weight vector (Improve signal strength) Weights reduced to 0.45); in typical scenarios (suburbs, coverage edges, minimal occlusion): the original weight vector is maintained. Finally, the overall membership degree of the original base station can be determined based on the weighted sum of each membership degree value and its corresponding index weight.

[0038] Optionally, determining the comprehensive membership degree corresponding to the original base station based on each membership degree value and its corresponding index weight includes: The original membership degree is generated by weighted summation of each membership degree value and its corresponding index weight. Determine the line-of-sight relationship corresponding to the original base station, wherein the line-of-sight relationship indicates whether there is an obstruction between the original base station and the satellite terminal to be matched; If the line-of-sight relationship indicates that there is no obstruction between the original base station and the satellite terminal to be matched, the original membership degree is determined as the comprehensive membership degree corresponding to the original base station; When the line-of-sight relationship indicates that there is obstruction between the original base station and the satellite terminal to be matched, the product of the original membership degree and the correction coefficient is determined as the comprehensive membership degree corresponding to the original base station.

[0039] In this embodiment, the original membership degree can be understood as a weighted sum of each membership degree value and its corresponding index weight. The line-of-sight relationship can be used to indicate whether there is obstruction between the original base station and the satellite terminal to be matched, and the degree of obstruction.

[0040] For example, the weighted average method is used to calculate the original membership degree. ,in, The range of values ​​is [0,1]. For the weight vector, The matrix formed by the membership values ​​consists of the membership values ​​corresponding to the evaluation indicators of each base station. , , , Composition. Based on terrain occlusion database data, the line-of-sight (LOS) relationship between the original base station and the satellite terminal to be matched is determined, divided into two scenarios: If the LOS relationship indicates no occlusion between the original base station and the satellite terminal to be matched, it is considered line-of-sight (LOS), meaning no significant or slight occlusion, and communication quality is stable; if the LOS relationship indicates occlusion between the original base station and the satellite terminal to be matched, it is considered non-line-of-sight (NLOS), meaning severe occlusion exists (such as tall buildings, mountains, vegetation), and communication quality is easily affected. In the case where the LOS relationship indicates no occlusion between the original base station and the satellite terminal to be matched, the original membership degree is... Determined as the comprehensive membership degree corresponding to the original base station When the line-of-sight relationship indicates that there is obstruction between the original base station and the satellite terminal to be matched, the original membership degree will be... and correction factor The product of these factors is used to determine the overall membership degree corresponding to the original base station. ,in, The correction coefficient is fixed at 0.7 and is used to reduce the matching priority of the original base station to avoid mismatches.

[0041] In one embodiment, the method for determining the original set of base stations includes: Based on the location information of ground base stations, a spatial index is constructed. The ground base stations include base stations contained in the environment where the satellite terminal to be matched is located. The spatial index is used to indicate the positional relationship between the satellite terminal to be matched and each of the ground base stations. Based on the location of the satellite terminal to be matched, a search is performed in the spatial index to obtain at least one search base station; For each retrieval base station, the path resource consumption corresponding to the retrieval base station is determined based on the working parameter data of the third base station corresponding to the retrieval base station, and the difference between the base station transmission power and the path resource consumption is determined as the terminal received signal strength. If the terminal received signal strength is greater than or equal to a preset threshold value, the retrieval base station is determined as the original base station. The set of all the original base stations is defined as the original base station set; The third base station's operating parameters include the parameters of the retrieval base station and information on simulated communication between the retrieval base station and the satellite terminal to be matched. The path resource consumption indicates the resource consumption during communication between the retrieval base station and the satellite terminal to be matched. The base station's transmission power includes the energy of the signal transmitted by the retrieval base station. The preset threshold value is related to the environment in which the retrieval base station is located.

[0042] In this embodiment, ground base stations can be understood as all base stations in the scene where the satellite terminal to be matched is located. A spatial index can be used to indicate the positional relationship between the satellite terminal to be matched and various ground base stations; the spatial index can be a tree structure constructed based on the latitude and longitude coordinates of various ground base stations. A retrieval base station can be understood as the base station in the leaf node of the satellite terminal to be matched in the spatial index, or a base station adjacent to the base station to be matched. Path resource consumption can be understood as the resource consumption when the retrieval base station communicates with the satellite terminal to be matched. Base station transmit power can be understood as the energy of the signal transmitted by the retrieval base station; base station transmit power can be used to indicate the strength of the signal transmitted by the retrieval base station. Base station transmit power is related to the scene where the retrieval base station is located; for example, the transmit power of a retrieval base station in an urban area, suburbs, or other locations is different. A preset threshold value can be understood as a value used to determine whether the satellite terminal to be matched is within the effective coverage area of ​​the retrieval base station; the preset threshold value is related to the environment where the retrieval base station is located.

[0043] For example, a spatial index is constructed based on the location information of ground base stations (e.g., latitude and longitude coordinates). This spatial index can be a quadtree spatial index. Each leaf node in the quadtree spatial index contains no more than 50 ground base stations. After the satellite terminal to be matched is located, a search is performed in the spatial index based on the location of the satellite terminal. The leaf node containing the satellite terminal and its four adjacent leaf nodes (approximately 250 ground base stations) are selected as at least one search base station. For each search base station, the corresponding third base station operating parameters are determined, and parameters used to calculate path resource consumption are selected from these parameters, including the base station operating frequency. Base station antenna height Base station transmission power and terminal antenna height The total path loss is calculated using the original formula of the COST231-Hata model. ,in, The antenna height correction factor for the satellite terminal to be matched is expressed in dB. It is calculated using the model's built-in standard method, and the formula is as follows: ,in The antenna height of the satellite terminal to be matched is 1.5m. This is a scene correction factor, measured in dB, with a value of 3dB for urban areas, 0dB for suburban areas, and 8dB for mountainous areas, reflecting the signal propagation attenuation characteristics of different scenarios. The base station transmit power... Path resource consumption The difference is determined as the terminal received signal strength. Set a preset threshold value, i.e. The default value is -120dBm, dynamically adjusted to -118dBm in urban areas and -122dBm in mountainous areas. This applies when the terminal receives a signal strength greater than or equal to the preset threshold. If the satellite terminal to be matched is determined to be within the effective coverage area of ​​the search base station, the search base station can be identified as the original base station. Finally, the set of all original base stations is identified as the original base station set.

[0044] Example 2 Figure 2 This is a flowchart of a target base station selection method according to Embodiment 2 of the present invention. This embodiment focuses on the target base station selection method described in the above embodiment. Figure 2 As shown, the method includes: S210. Determine the satellite terminal to be matched, and the original base station set corresponding to the satellite terminal to be matched.

[0045] S220. Based on the first base station operating parameter data corresponding to each original base station in the original base station set, at least one candidate base station is selected from the original base station set.

[0046] S230. For each candidate base station, determine the candidate base station score based on the second base station operating parameter data corresponding to the candidate base station.

[0047] In this embodiment, the second base station operating parameter data can be understood as the base station operating parameter data corresponding to the candidate base station. The second base station operating parameter data can be formed by the parameters of the candidate base station and the information of the simulated communication between the candidate base station and the satellite terminal to be matched. The parameters of the candidate base station may include the parameters of the candidate base station itself.

[0048] Specifically, for each candidate base station, the operating parameters of the corresponding second base station are first determined, and the candidate base station score is calculated based on these operating parameters. The candidate base station score can be jointly calculated based on factors such as signal strength, channel quality, matching stability, and base station load, which are included in the operating parameters of the second base station.

[0049] Optionally, determining the candidate base station score based on the second base station operating parameter data corresponding to the candidate base station includes: At least one decision factor corresponding to the candidate base station is selected from the second base station operating parameter data. The at least one decision factor includes a second signal strength, channel quality, matching stability, and base station load. The second signal strength indicates the communication quality of the candidate base station. The channel quality indicates the anti-interference capability of the signal transmitted by the candidate base station. The matching stability includes the success rate of communication between the candidate base station and terminals other than the satellite terminal to be matched. The base station load indicates the number of terminals connected to the candidate base station. Determine the decision weights of each of the aforementioned decision factors; Each of the aforementioned decision factors is quantified to generate a quantified factor score corresponding to each of the aforementioned decision factors; The candidate base station score is generated by weighted summation of the scores of each quantification factor and its corresponding decision weight.

[0050] In this embodiment, decision factors can be understood as indicators used to calculate candidate base station scores. These decision factors can be indicators selected from the second base station operating parameter data, including the candidate base station's second signal strength, channel quality, matching stability, and base station load. Second signal strength indicates the communication quality of the candidate base station. Channel quality indicates the anti-interference capability of the signal transmitted by the candidate base station, and can be obtained from measured data of the satellite terminal to be matched. Matching stability can be understood as the success rate of communication between the candidate base station and terminals other than the satellite terminal to be matched, such as the historical matching success rate of a mobile phone or communication terminal with the candidate base station. Base station load indicates the number of terminals connected to the candidate base station; the lower the base station load, the more guaranteed the communication quality. Decision weights can be understood as the weights determined for each decision factor, which can be used to determine the importance of each decision factor to the candidate base station score. Quantized factor scores can be understood as the quantified values ​​of each decision factor.

[0051] For example, at least one decision factor corresponding to a candidate base station is selected from the second base station operating parameter data, including: second signal strength. The unit is dBm, and the value range is ≥-120dBm; channel quality The unit is dB, and the value ranges from 0 to 30 dB; matching stability The value ranges from 0 to 1 (i.e., 0% to 100%); base station load The value ranges from 0 to 1 (i.e., 0% to 100%). Determine the decision weights for each decision factor and set up a weight vector.
