[0001] The present invention relates to the field of mobile positioning technology, and in particular to a positioning service method, system and positioning server based on mobile communication. Background Art

[0002] With the widespread application of 5G technology, users have increasingly higher requirements for the accuracy and real-time performance of positioning services. Traditional positioning methods, such as GPS, are often affected by non-line-of-sight propagation (NLOS) when facing complex environments (such as urban canyons and indoor environments), resulting in a significant decrease in positioning accuracy. In order to solve this problem, positioning technology based on artificial intelligence (AI) has gradually become a hot topic in research and application. By adopting machine learning and deep learning algorithms, AI positioning technology can significantly improve positioning accuracy, especially in complex environments.

[0003] Although AI positioning technology has shown great potential in improving positioning accuracy, its application also faces some challenges. How to ensure that only qualified users can use this advanced positioning technology and achieve efficient selection and reselection of the Location Management Function (LMF) is a problem that needs to be solved in providing positioning services. In response to this, some solutions currently introduce a positioning service authorization mechanism based on user subscription data, which authorizes and manages specific positioning services by setting up a user subscription database in the network.

[0004] However, these existing solutions often have shortcomings. For example, they usually only randomly select a model from a large number of AI positioning models as the target model based on the user's subscription data. This random selection method fails to fully consider the comprehensive performance of each AI positioning model, resulting in a poor user experience, unable to effectively meet users' needs for high-precision and high-real-time positioning services, and unable to achieve effective use of positioning resources. Summary of the invention

[0026] Figure 2 This is the signaling execution process of the positioning service method in the embodiment of the present invention. DETAILED DESCRIPTION

[0027] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0028] This embodiment discloses a positioning service method based on mobile communication, which is used to provide AI positioning service according to the positioning request sent by the mobile terminal device. First of all, it should be noted that the specific positioning method of the AI ​​positioning service belongs to the conventional technology in this field and will not be repeated here.

[0029] like Figure 1 , the positioning service method includes the following process:

[0030] S1: Receive a positioning request from a terminal device, which includes positioning requirement information and identity information. Positioning requirement information refers to the type of positioning currently required by the user, such as navigation positioning, tracking positioning, weather service positioning, etc. Identity information includes the unique device code of the terminal device.

[0031] S2: Based on the identity information, query the subscription service set related to the positioning service of the terminal device to obtain subscription status information.

[0032] S3: When the subscription status information shows that the terminal device subscribes to the AI ​​positioning service, obtain a list of currently available positioning models, which contains several intelligent positioning models that can provide AI positioning services. In addition, when the subscription status information shows that the terminal device has not subscribed to the AI ​​positioning service, provide positioning services for the terminal device based on traditional commonly used positioning service methods.

[0033] S4: Evaluate the performance status of each smart positioning model in the positioning model list according to a plurality of preset evaluation indicators to obtain a plurality of comprehensive capability data corresponding to each smart positioning model, wherein each evaluation indicator is used to evaluate the performance status of the smart positioning model in one aspect. The comprehensive capability data represents the comprehensive performance of the corresponding smart positioning model.

[0034] S5: Select one of the intelligent positioning models based on the ranking and selection strategy of the comprehensive capability data to obtain a target positioning model.

[0035] S6: Provide positioning services for terminal devices based on the target positioning model.

[0036] It should also be noted that the performance status of the intelligent positioning model can be evaluated using a trained neural network model, or it can be evaluated according to a preset evaluation strategy. The specific process of the evaluation belongs to conventional means in the art and will not be described in detail here.

[0037] On the other hand, the comprehensive capability data is sorted from high to low, and the smart positioning model with the highest or lowest ranking is selected as the target positioning model. When the strategy is selected to select the smart positioning model with the highest ranking as the target positioning model, a high-quality positioning service can be provided to the user, effectively ensuring the positioning quality. When the strategy is selected to select the smart positioning model with the lowest ranking as the target positioning model, while ensuring that sufficient positioning services are provided to the user, positioning service resources are effectively saved, and the rational use of positioning service resources is achieved.

[0038] Specifically, the evaluation indicators include a first indicator, a second indicator and a third indicator. The first indicator is used to reflect the load status of the intelligent positioning model, the second indicator is used to reflect the network status of the intelligent positioning model (including bandwidth, network speed, etc.), and the third indicator is used to reflect the positioning capability of the intelligent positioning model.

[0039] More specifically, the third indicator includes positioning accuracy and response time.

[0040] Based on the positioning service method provided in this embodiment, when it is found that the user has subscribed to the AI ​​positioning service, the performance status of each intelligent positioning model in the positioning model list will be evaluated first, and comprehensive capability data representing the comprehensive capability of the intelligent positioning model will be generated, and then the target positioning model will be selected based on the comprehensive capability data. Based on this positioning service method, the intelligent positioning model expected by the user can be selected, which effectively improves the user experience and facilitates the service provider to provide differentiated services for different positioning service needs.

[0041] On the other hand, the weights of several evaluation indicators can also be dynamically adjusted based on the positioning demand information. Thus, for the same intelligent positioning model, different comprehensive capability data can be obtained according to the different positioning needs of users, so as to select a positioning model that better matches the user's needs. For example, when the terminal device issues a positioning demand requiring navigation positioning, the weight of the evaluation indicators related to positioning accuracy can be increased, and when the terminal device issues a positioning demand requiring weather positioning, since the positioning accuracy requirements are lower, the weight of the evaluation indicators related to positioning accuracy can be lowered, and the weight of the evaluation indicators related to load conditions or network status can be increased.

[0042] On the other hand, the positioning report from the terminal device is collected and analyzed. The positioning report contains key information related to positioning accuracy. When the positioning accuracy is less than the preset value, the status of each smart positioning model in the positioning model list is re-evaluated and the target positioning model is selected. In this way, the user's experience continuity and service quality during the location service process can be ensured.

[0043] Furthermore, when the above-mentioned positioning service method is used in 5G or a new generation of evolved communication networks, the user's subscription status information is stored through the unified data management function UDM, the access and mobility management function AMF is used as a control node, and the target positioning model is run through the location management function LMF.

[0044] After receiving the positioning request from the terminal device, AMF will intelligently select the intelligent positioning model that supports the AI ​​positioning function according to the subscription status information provided by UDM to obtain the target positioning model.

[0045] LMF runs the target positioning model to generate the location information required by the terminal device.

[0046] In addition, AMF can also obtain a list of available positioning models by querying the network storage function NRF.

[0047] In summary, the present invention discloses a positioning service method based on mobile communication, such as Figure 2 , its service process is as follows:

[0048] 1. The terminal device UE initiates a positioning request to the AMF;

[0049] 2. AMF queries UDM for the service subscription set;

[0050] 3. UDM returns subscription status information to AMF;

[0051] 4. AMF queries NRF for a list of positioning models;

[0052] 5. NRF returns the positioning model list to AMF;

[0053] 6. Based on the comprehensive capability data obtained from the evaluation, AMF selects the top-ranked intelligent positioning model 1 as the target positioning model;

[0054] 7. AMF forwards the positioning request to the target positioning model in LMF;

[0055] 8. The target positioning model performs AI positioning and returns the generated location information to AMF;

[0056] 9. AMF forwards the received location information to the UE.

[0057] In another preferred embodiment of the present invention, a positioning server is also disclosed, which includes a positioning matching module, and the positioning matching module provides positioning services for terminal devices based on the above-mentioned positioning service method based on mobile communication.

[0058] The present invention also discloses another positioning service system, which includes one or more processors, a memory and one or more programs, wherein the one or more programs are stored in the memory and are configured to be executed by the one or more processors, and the program includes instructions for executing the positioning service method as described above. The processor can adopt a general central processing unit (CPU), a microprocessor, an application-specific integrated circuit (ASIC), or one or more integrated circuits to execute related programs to implement the functions required to be executed by the modules in the positioning service system of the embodiment of the present application, or to execute the positioning service method of the method embodiment of the present application.

[0059] The present invention also discloses a computer-readable storage medium, which includes a computer program, and the computer program can be executed by a processor to complete the positioning service method as described above. The computer-readable storage medium can be any available medium that can be accessed by a computer or a data storage device such as a server or a data center that includes one or more available media integrated. The available medium can be a read-only memory (ROM), or a random access memory (RAM), or a magnetic medium, such as a floppy disk, a hard disk, a tape, a magnetic disk, or an optical medium, such as a digital versatile disc (DVD), or a semiconductor medium, such as a solid state disk (SSD), etc.

[0060] The embodiment of the present application also discloses a computer program product or a computer program, which includes a computer instruction stored in a computer-readable storage medium. A processor of an electronic device reads the computer instruction from the computer-readable storage medium, and the processor executes the computer instruction, so that the electronic device performs the above-mentioned positioning service method.

[0061] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
