Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a positioning method, electronic device, storage medium, and program product. Background Technology

[0002] A Global Navigation Satellite System (GNSS) is a satellite-based radio navigation system that provides time and space references as well as real-time dynamic information related to location. GNSS can provide positioning services to user equipment by using ranging methods, that is, by measuring the distance between the satellite and the terminal equipment to calculate the position of the terminal equipment.

[0003] In scenarios with no or weak GNSS signals, terminal devices can obtain their location information through the location services provided by their contracted operators. However, the coverage of these operators' location services is limited, and if the terminal device is outside the coverage area of ​​the contracted operator's location services, it may be unable to obtain location services. Summary of the Invention

[0004] This disclosure provides a positioning method, electronic device, storage medium, and program product that can expand the scope of location services provided by operators, enabling terminal devices to obtain location services even when they are not within the service area of ​​a contracted operator.

[0005] To achieve the above objectives, the present disclosure adopts the following technical solution:

[0006] Firstly, this disclosure provides a positioning method, which includes:

[0007] Send service request information to the access network device; wherein, the access network device belongs to the first operator who has not signed a contract with the terminal device, and the service request information is used to request the first operator to provide location services in the absence of a contract;

[0008] Receive location service indication information sent by the access network device. The location service indication information is used to indicate that the access network device can provide location services for the terminal device.

[0009] In response to the location service instruction information, a location request information is sent to the access network device;

[0010] Location information of terminal devices is obtained through the location service of the primary operator.

[0011] Secondly, this disclosure also provides another positioning method, which includes:

[0012] Receive service request information sent by terminal equipment; wherein, the access network equipment belongs to the first operator who has not signed a contract with the terminal equipment, and the service request information is used to request the first operator to provide location services in the absence of a contract;

[0013] Based on the service demand information, a location service instruction information is sent to the terminal device. The location service instruction information is used to instruct the access network device to provide location services to the terminal device.

[0014] Receive location request information sent by the terminal device;

[0015] Positioning measurements are performed on the terminal device to obtain its positioning information.

[0016] Thirdly, this disclosure also provides an electronic device, including:

[0017] The sending module is used to send service request information to the access network equipment. The access network equipment belongs to a first-tier operator with which the terminal equipment has not signed a contract, and the service request information is used to request the first-tier operator to provide location services in the absence of a contract.

[0018] The receiving module is used to receive location service indication information sent by the access network device. The location service indication information is used to indicate that the access network device can provide location services for the terminal device.

[0019] In response to the location service indication information, the sending module is also used to send location request information to the access network device.

[0020] The receiving module is also used to acquire positioning information obtained by the access network equipment from positioning measurements of the terminal equipment.

[0021] Fourthly, this disclosure also provides an electronic device, including:

[0022] The receiving module is used to receive service request information sent by the terminal device; wherein, the access network device belongs to the first operator who has not signed a contract with the terminal device, and the service request information is used to request the first operator to provide location services in the absence of a contract.

[0023] The sending module is used to send location service indication information to the terminal device according to the service demand information. The location service indication information is used to instruct the access network device to provide location services to the terminal device.

[0024] The receiving module is also used to receive location request information sent by the terminal device;

[0025] The sending module is also used to perform positioning measurements on the terminal device to obtain the positioning information of the terminal device.

[0026] Fifthly, an electronic device is provided, comprising: a processor and a memory; the memory storing processor-executable instructions; when the processor is configured to execute the instructions, causing a communication device to implement any of the methods provided in the first to second aspects above.

[0027] A sixth aspect provides a computer-readable storage medium that stores computer instructions that, when executed on a computer, cause the computer to perform any of the methods provided in the first or second aspect.

[0028] In a seventh aspect, a computer program product comprising computer instructions is provided, which, when executed on a computer, cause the computer to perform any of the methods provided in the first or second aspect.

[0029] Based on the technical solution provided in this disclosure, terminal devices can request location services from access network devices even without a contract with an operator. This separates the location service itself from core network authentication, enabling the provision of location services without core network registration and authentication. In other words, network operators can provide location services to uncontracted terminals, thereby expanding the scope of the operator's location service and allowing terminal devices outside the service area of ​​contracted operators to obtain location services, thus improving the availability of location services for terminal devices. Furthermore, based on the location method provided in this disclosure, terminal devices do not need to interact with the location server or complete core network registration and authentication to obtain location information, improving location speed. Moreover, since terminal devices can obtain location information without core network registration and authentication, the location service is decoupled from other core network services, preventing interference with other services and ensuring network service stability.

[0043] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0044] Unless the context otherwise requires, throughout the specification and claims, the term "comprise" and its other forms, such as the third-person singular "comprises" and the present participle "comprising," are interpreted as open-ended and encompassing, meaning "including, but not limited to."

The illustrative representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics mentioned may be included in any suitable manner in any one or more embodiments or examples.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0046] In this disclosure, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0047] In addition, the use of “based on” implies openness and inclusivity, because processes, steps, calculations or other actions “based on” one or more of the stated conditions or values ​​may in practice be based on additional conditions or values ​​beyond those stated.

[0048] Mobile communication technology has brought about a wide variety of value-added services. Location-based services (LBS) have quietly emerged as a new type of value-added service provided by mobile communication networks. With the development of mobile communication technology, fifth-generation (5G) technology uses new coding methods, beamforming, massive MIMO, millimeter-wave spectrum, and other key technologies. Its large bandwidth and antenna array technology provide the foundation for high-precision distance and angle measurement. 5G enables denser network deployments, significantly increasing base station density. This facilitates high-precision positioning through multi-base station collaboration. In related technical fields, positioning methods such as Enhanced Cell-ID (ECID), Multi-Round Trip Time (Multi-RTT), Downlink Angle of Departure (DL-AOD), Downlink Time Difference of Arrival (DL-TDOA), Uplink Time Difference of Arrival (UL-TDOA), and Uplink Angle of Arrival (UL-AOA) have been developed. These methods can achieve sub-meter level positioning accuracy, greatly expanding the application scenarios of positioning. Taking the application scenario of positioning services for vehicle terminals and user terminals as an example, this positioning service can effectively solve the technical problems of finding vehicles and people in Autonomous Valet Parking (AVP) applications in scenarios with no (or weak) GNSS signals. However, most parking lots may have one or a few operators providing high-precision positioning services. If these operators are not contracted with the vehicle terminal or user terminal, the vehicle terminal or user terminal may not be able to obtain positioning services.

[0049] It is evident that how to provide location services for terminal devices located outside the coverage area of ​​the location services of contracted operators is a technical problem that urgently needs to be solved in related technical fields.

[0050] In view of this, the present disclosure provides a positioning method in which a terminal device sends service request information to an access network device; wherein the access network device belongs to a first operator with which the terminal device has not signed a contract, and the service request information is used to request the first operator to provide positioning services in the absence of a contract; the terminal device receives positioning service indication information sent by the access network device, the positioning service indication information being used to indicate that the access network device can provide positioning services for the terminal device; in response to the positioning service indication information, the terminal device sends positioning request information to the access network device; and the terminal device obtains positioning information obtained by the access network device through positioning measurement of the terminal device.

[0051] As can be seen, terminal devices can request location services from access network devices even without a contract with an operator. This separates the location service itself from core network authentication, enabling the provision of location services without core network registration and authentication. In other words, network operators can provide location services to uncontracted terminals, thereby expanding the scope of the operator's location service and allowing terminal devices outside the service area of ​​contracted operators to obtain location services, thus improving the availability of location services for terminal devices. Furthermore, based on the location method provided in this disclosure, terminal devices do not need to interact with the location server or complete core network registration and authentication to obtain location information, improving location speed. Moreover, since terminal devices can obtain location information without core network registration and authentication, the location service is decoupled from other core network services, preventing interference with other services and ensuring network service stability.

[0052] In some embodiments, this disclosure provides a network access procedure, such as Figure 1 As shown, it includes:

[0053] 1. Downlink Synchronization: The terminal device receives the synchronization signal (SSB / PBCH) from the access network device and performs an initial cell search, including coarse synchronization and fine synchronization, to ensure time and frequency synchronization with the access network device.

[0054] 2. The terminal device receives and parses the System Information Block (SIB). The information block may contain key information such as access network equipment configuration, cell configuration, and access parameters.

[0055] 3. Random Access Process (RACH Process): The terminal device can select and send a random access preamble to the access network device. After the access network device responds, the terminal device completes uplink synchronization to ensure that the terminal device can send data to the access network device.

[0056] Thus, the terminal equipment and the access network equipment complete beam detection and up / down radio channel synchronization.

[0057] 4. Radio Resource Control (RRC) establishment. This includes Radio Channel Setup.

[0058] 5. Registration Request: The terminal device sends a registration request to the access network device, requesting access to the access network device and to obtain services. This may include the terminal device identifier (UE ID), the terminal device's access network device capabilities, and the requested access network device slice.

[0059] 6. Authentication Process: The access network device authenticates the terminal device to ensure the security of the access device.

[0060] 7. Security Process: An encrypted secure connection is established between the terminal device and the access network device to protect the confidentiality and integrity of data transmission.

[0061] 8. Registration Accept: The access network device confirms the registration request of the terminal device, completes the registration process, and allows the terminal device to access the access network device.

[0062] 9. Radio Resource Control Reconfiguration (RrcReconfiguration): The access network equipment reconfigures the radio resources of the terminal equipment according to the needs of the terminal equipment and the status of the access network equipment to optimize communication efficiency.

[0063] 10. PDU Session Establishment Request: The terminal device requests to establish a PDU session in order to transmit user data in the access network device.

[0064] 11. PDU Session Establishment Accept: The access network device accepts the session establishment request from the terminal device and confirms that the session has been successfully established.

[0065] The terminal device negotiates with the access network device regarding the PDN session type and protocol configuration options (PCO) corresponding to the Data Access Network Device Name (DNN), determining the data transmission path and method. The access network device assigns a PDN address (IP address) to the terminal device as its unique identifier within the access network, and configures Quality of Service (QoS) rules for the terminal device to ensure data transmission priority and performance. Finally, the terminal device negotiates and selects a suitable access network device slice DNN to optimize data transmission efficiency and reliability.

[0066] Based on this network access process, before using the operator's services, it is necessary to register and authenticate on the operator's 5G core network. Then, a connection is established with the core network element AMF via NAS non-access signaling before the location service can be started. If the terminal has not signed a contract with the operator, authentication will fail and network registration will fail, thus preventing the use of any services provided by the operator.

[0067] Taking vehicle-mounted terminals and user terminals as examples, the contracted operators of vehicle-mounted terminals and user terminals are different. The application used for positioning (third-party positioning application service) can connect to the positioning service platforms of different operators at the same time. Thus, terminals (vehicle-mounted terminals and user terminals) that are contracted with different operators only need to register in their respective mobile operator networks. The positioning calculation engine of each mobile operator can collect the location information of the terminal being served. Then, the third-party positioning application service can obtain the location information of these terminals from the positioning service platform of the operator and provide the location information to the terminal.

[0068] like Figure 2As shown, operator A provides location services and internet data access services to vehicle terminal A1 using the A 5G network. For example, vehicle terminal A1 uses operator A's SIM card, and it has a data channel and a positioning measurement channel with operator A's access network equipment (5G RAN). Operator B provides location services and internet data access services to user terminal B1 using the B 5G network. For example, user terminal B1 uses operator B's SIM card, and it has a data channel and a positioning measurement channel with operator B's access network equipment. Third-party location application services can interface with the location service platforms of operators A and B. The third-party location application service obtains the terminal's location information from the operator's location service platform based on the terminal identifier, and then sends it to the terminal requesting the location information, such as the vehicle terminal and the user terminal, via the internet data channel (each terminal also needs to have the third-party location application service client installed). In some embodiments, the third-party location application service may also include indoor navigation, business intelligence (BI) analytics, smart parking, property management, etc.

[0069] However, third-party location-based applications need to interface with the location service platforms of different operators, which is costly and complex. Furthermore, in situations where only one or some operators provide high-precision location services at the current location (e.g., a parking lot), Figure 2 The positioning scheme shown may not be feasible.

[0070] For example, operator B's network can provide both high-precision positioning and internet access services in the parking lot, while operator A's network can only provide internet access (not high-precision positioning). Therefore, operator A's terminal will not be able to obtain positioning services in that parking lot. Figure 3 As shown, operator A's vehicle terminal A1 cannot use the 5G network in this parking lot to implement the AVP (Available Viewer) service for finding cars or vice versa. Alternatively, as... Figure 4 As shown, the parking lot is provided with 5G positioning services by operator C. At this time, neither vehicle terminal A1 (which has a contract with operator A) nor user terminal B1 (which has a contract with operator B) can obtain positioning services.

[0071] Therefore, this disclosure separates the location service itself from the core network identity authentication, enabling network operators to provide location services to uncontracted terminals, thereby expanding the scope of the operator's location service provision and allowing terminal devices to obtain location services even when they are not within the service range of a contracted operator.

[0072] like Figure 5 As shown, this disclosure also provides a communication system. The communication system 100 includes a terminal device 10 and an access network device 20.

[0073] For example, terminal 10 can be a transportation vehicle, a mobile terminal, or other possible device. Transportation vehicles can include vehicles such as cars, buses, subways, light rail, and trams; ships such as passenger ships, cargo ships, tankers, fishing boats, and yachts; and aircraft such as passenger planes, cargo planes, and helicopters. Transportation vehicle equipment (i.e., terminal 10) can be a terminal configured within the aforementioned transportation vehicle, such as an in-vehicle terminal. Mobile terminal devices can also be called terminals, mobile stations, mobile terminals, etc. Mobile terminal devices can be, for example, mobile phones, tablets, desktop computers, laptops, handheld computers, notebook computers, ultra-mobile personal computers (UMPCs), netbooks, etc.

[0074] In some embodiments, terminal 10 may have a direct communication module, which allows communication with other devices. This direct communication module can be at least one of a cellular vehicle-to-everything (C-V2X) direct communication module or a dedicated short-range communications (DSRC) direct communication module. Alternatively, terminal 10 may also have a wireless network communication module, such as at least one of a terrestrial network communication module or a non-terrestrial network communication module. The terrestrial network communication module can be a cellular mobile network communication module (e.g., 2G / 3G / 4G / 5G), an Ethernet communication module, a wireless local area network (WLAN) communication module, or a dedicated communication network (e.g., fiber optic cable) communication module.

[0075] Access network device 20 can provide wireless access services to terminals. Specifically, each network device corresponds to a service coverage area. Terminals entering this area can communicate with the access network device to receive the wireless access services provided by the network device. Access network device 20 can be any device with wireless transceiver capabilities, such as an evolved NodeB (eNB), a next-generation NodeB (gNB), a transmission receive point (TRP), a transmission point (TP), or some other access node. Based on the size of the service coverage area provided, base stations can be further divided into macro base stations for providing macro cells, micro base stations for providing micro cells, and femto base stations for providing femto cells. As wireless communication technology continues to evolve, future base stations may also adopt other names.

[0076] In some embodiments, terminal device 10 may send service request information to access network device 20. In this case, access network device 20 may belong to a first operator with which the terminal device has not signed a contract.

[0077] Understandable, Figure 5 The system architecture shown does not constitute a limitation on the embodiments of this disclosure, and may include more or fewer devices or components than shown, or combine certain components, or have different component arrangements.

[0078] The method provided in this disclosure will now be described in detail with reference to the accompanying drawings.

[0079] like Figure 6 As shown in the embodiments of this disclosure, a positioning method is provided and applied to a terminal device. The method includes:

[0080] S101. Send service request information to the access network equipment.

[0081] The access network equipment belongs to the first operator that has not signed a contract with the terminal equipment.

[0082] For example, the contracted operator of the terminal device can be a second operator, but the second operator cannot provide location services for the current location of the terminal device. That is, the terminal device is outside the coverage of the location service of the contracted second operator. In this case, the terminal device can send service request information to the access network equipment of the first operator. The service request information is used to request the first operator to provide location services without a contract.

[0083] In some embodiments, a first operator can provide location services for the current location of a terminal device, and the terminal device can identify the first operator among multiple operators.

[0084] In some embodiments, the service request information may include at least one of the following: identification information of the terminal device and indication information of the requested location service.

[0085] Among them, the identification information of the terminal device is used to uniquely identify the characteristic information of the terminal device. Based on the identification information, the terminal device can be accurately identified or associated.

[0086] For example, the identification information of a terminal device can be the International Mobile Equipment Identity (IMEI), MAC address, serial number, IP address, device name, mobile phone number, etc.

[0087] The aforementioned location service request information is used to indicate the type of service required by the terminal device, i.e., location service.

[0088] In some embodiments, the indication information of the location service demand can be used to indicate that the terminal device currently demands a location service.

[0089] For example, the indication information for the demand for location services can be used to indicate that the terminal device currently demands location services among multiple services, or that the terminal device currently only demands location services.

[0090] S102. Receive location service indication information sent by the access network device.

[0091] Among them, the location service indication information is used to indicate that the access network equipment can provide location services for the terminal equipment.

[0092] For example, in response to a service request from a terminal device, an access network device can determine whether it can provide location services to the terminal device. If the access network device can provide location services to the terminal device, it sends location service indication information to the terminal device.

[0093] In some embodiments, location service indication information can also be used to instruct the terminal device to send specific location request information to the access network device.

[0094] S103. In response to the location service instruction information, send a location request information to the access network device.

[0095] The location request information is used to request the location information of the terminal device from the access network device.

[0096] In some embodiments, the location request information includes at least one of the following:

[0097] The terminal device's identification information, the relevant information of the detection reference signal, the identification information of the application used for positioning, the service type information, the terminal device's reference location information, and the terminal device's expected positioning accuracy information.

[0098] The identification information of the terminal device can be referred to the relevant description in step S101 above, and will not be repeated here.

[0099] A sounding reference signal refers to a reference signal used to measure position, such as a sounding reference signal (SRS), a channel state information-reference signal (CSI-RS) used for auxiliary positioning, or other possible reference signals. Relevant information about the sounding reference signal includes parameters such as signal strength, time of arrival, angle of arrival, and positioning measurement time.

[0100] The identification information used for location services is a unique identifier for the application requesting location services. This can be the application's name or a unique ID provided by the developer.

[0101] Service type information refers to the type of service that the terminal device needs to complete using the location service. For example, the "vehicle-to-person / person-to-vehicle" service type requires location services from both the vehicle terminal and the user terminal. Other examples include emergency rescue services, logistics and delivery services, and navigation services.

[0102] The reference location information of the terminal device may include a rough location or historical location information provided by the terminal, such as the historical location information determined when the terminal device was last able to obtain location services.

[0103] The desired positioning accuracy information of a terminal device refers to the positioning accuracy level requested by the terminal device, such as ≤1m, ≤5m, etc.

[0104] In some embodiments, the terminal device may also obtain the detection reference signal resources allocated by the access network device for positioning based on the positioning request information of the terminal device.

[0105] For example, the access network device can also determine the access network device resources required for the measurement, such as which base stations and network elements participate in the positioning measurement of the terminal device.

[0106] In some embodiments, the terminal may also send a probe reference signal based on the probe reference signal resources allocated by the access network device.

[0107] S104. Obtain the location information of the terminal device through the location service of the first operator.

[0108] In some embodiments, the location information includes at least one of the following:

[0109] The terminal device's identification information, location coordinates, positioning accuracy, positioning technology, moving speed, moving direction, and environmental perception information.

[0110] The identification information of the terminal device can be referred to the relevant description in step S101 above, and will not be repeated here.

[0111] Location coordinates, such as two-dimensional coordinates (latitude and longitude) or three-dimensional coordinates (latitude, longitude and altitude).

[0112] The positioning accuracy can be referred to the relevant description in step S102 above, and will not be repeated here.

[0113] Positioning technology refers to the technical means used to achieve positioning, such as the Global Positioning System (GPS), BeiDou, Wi-Fi positioning, Bluetooth positioning, and cellular positioning.

[0114] Moving speed refers to the current moving speed of the terminal, which can be used to determine the motion state (stationary / moving) of the terminal device and to predict the device trajectory, etc.

[0115] The direction of movement refers to the current direction of movement of the terminal, which is usually represented by an angle or direction name (such as east, south, west, north or a specific angle value).

[0116] Environmental perception information includes information about the current environment of the terminal device, such as road congestion, pedestrian positions, vehicle speed and direction, and the status of road signs and traffic lights.

[0117] Therefore, for a terminal device that is not contracted with a first-party operator, the operators providing the location service and the operators providing the data service can be different. Based on this technical solution, any terminal device can request location services from any operator's radio access network (RAN).

[0118] In one possible implementation, the terminal device can obtain positioning information obtained by the access network device from positioning measurements of the terminal device on the positioning application.

[0119] The location-based applications also provide location information for other terminal devices.

[0120] For example, a terminal device can use a data channel of a contracted operator to access the location service platform of the first operator through a location application (a third-party location application service), and obtain location information based on the terminal device's identification information. Figure 7 As shown, User Equipment A (UE A) is a contracted terminal device of Operator A. UE A can obtain location information from the location measurement performed on UE A by the access network equipment of Operator B. At this time, UE A can use Operator A's data channel to access Operator B's location service platform through a location application (third-party location application service) and obtain location information based on the identification information of UE A.

[0121] In some embodiments, other terminal devices (such as Figure 7 The UE (C) shown can also obtain the location information of the terminal device on the application used for positioning.

[0122] For example, other terminal devices can also use the data channels provided by their respective contracted operators to access the location service platform of the operator providing the location service through a third-party location application service to obtain the location information of the terminal device.

[0123] In another possible implementation, the terminal device can use the positioning service interface provided by the first operator to obtain the positioning information obtained by the access network device from the positioning measurement of the terminal device.

[0124] The location information was determined by the location server provided by the first operator.

[0125] For example, the access network device may notify other access network devices participating in the positioning measurement of the terminal device to measure the detection reference signal emitted by the terminal device for positioning, and send the obtained positioning measurement result to the positioning server of the first operator. For example, the positioning server mentioned above refers to a server entity responsible for processing positioning requests, which may include a positioning engine, such as a location management function (LMF).

[0126] Therefore, the first operator's positioning server can perform positioning analysis and calculation based on the positioning measurement results sent by each access network device participating in the positioning measurement of the terminal device, obtain the positioning calculation result (i.e., the positioning information of the terminal device), and output the positioning information of the terminal device through the positioning service interface provided by the first operator. At this time, the terminal device can use the positioning service interface provided by the first operator to obtain the positioning information obtained by the access network devices from the positioning measurement of the terminal device.

[0127] In some embodiments, the positioning server of the first operator can send the positioning information and identification information of the terminal device to the positioning service platform of the first operator. The positioning service platform of the first operator provides a service to applications used for positioning, through a standard interface, to query the positioning information of the terminal device based on its identification information. At this time, the terminal device can also obtain positioning information obtained by the access network device from positioning measurements performed on the terminal device within the positioning application.

[0128] Based on the technical solution provided in this disclosure, a terminal device can request location services from an access network device even without a signed contract with an operator. This separates the location service itself from core network authentication, enabling the provision of location services without core network registration and authentication. In other words, network operators can provide location services to unsigned terminals, thereby expanding the scope of the operator's location services and allowing terminal devices outside the service area of ​​signed operators to obtain location services, thus improving the availability of location services for terminal devices. Furthermore, based on the location method provided in this disclosure, the terminal device does not need to interact with the location server or complete core network registration and authentication to obtain location information, improving location speed. Moreover, since the terminal device can obtain location information without completing core network registration and authentication, the location service is decoupled from other core network services, preventing interference with other services and ensuring the stability of network services.

[0129] In some embodiments, such as Figure 8 As shown, before sending service request information to the access network device, the method further includes:

[0130] S201. Obtain information from at least one operator capable of providing location services for the current location of the terminal device.

[0131] It should be understood that at least one operator should include the aforementioned first operator.

[0132] In one possible implementation, the terminal device can obtain information from at least one operator on an application used for positioning that can provide positioning services for the terminal device's current location.

[0133] For example, a terminal device can obtain information about at least one operator that can provide location services for the current location of the terminal device through a data channel of a contracted second operator on an application used for positioning.

[0134] In this way, location-based applications can integrate location resources from multiple operators, thereby providing users with more comprehensive and accurate location information.

[0135] In another possible implementation, the terminal device can also obtain location service capability information broadcast by the access network equipment of various operators. Based on this information, it can then determine at least one operator capable of providing location services for the terminal device's current location. This allows it to obtain information about at least one operator capable of providing location services for the terminal device's current location.

[0136] The aforementioned location service capability information can be used to describe the type, accuracy, coverage, network coverage, and signal strength of the location services that the operator can provide at the current location.

[0137] Therefore, after receiving the location service capability information broadcast by the access network equipment of various operators, the terminal device can determine the most suitable location service for itself based on its current location, location needs, and the location service capability information of the operators.

[0138] S202. Based on information from at least one operator, establish a connection with the access network equipment of the first operator.

[0139] For example, the terminal device can search for the spectrum signal of the first operator, complete the air interface access with the access network equipment of the first operator, and establish a radio resource control (RRC) channel connection.

[0140] In some embodiments, the number of operators capable of providing location services for the current location of the terminal device is multiple.

[0141] In some embodiments, the terminal device can determine the location service information of each of the multiple operators. Based on the location service information of each operator, a first operator that meets the positioning requirements of the terminal device is determined among the multiple operators, and a connection is established with the access network equipment of the first operator based on the information of the first operator.

[0142] In some embodiments, location service information includes at least one of the following: location method support, location performance, location-related signal parameters, network quality, security information, and operator preset priorities.

[0143] Location method support refers to the location methods supported by the operator.

[0144] Location performance can include information about the operator's location service capabilities at the current location, such as location service type, accuracy, coverage, network coverage, and signal strength.

[0145] Positioning-related signal parameters include signal strength, signal quality, signal coverage, and other positioning-related parameters.

[0146] Network quality refers to the network quality of the operator at the current location, such as network stability, bandwidth, latency, and other network performance indicators.

[0147] Security information may include the level of data security or data security measures that the operator can provide at the current location.

[0148] The operator's preset priorities can include priorities set for common operators, such as those based on operator service fees and business policies. These preset priorities can be set by the terminal device, the location-based application, or by the user.

[0149] Based on the above embodiments, the terminal device can determine a suitable first operator that can provide location services for the current location of the terminal device, thereby establishing a connection with the first operator and improving the stability and accuracy of the location service.

[0150] In some embodiments, such as Figure 9 As shown, this disclosure also provides another positioning method, applied to access network equipment, including:

[0151] S301, Receive service request information sent by terminal equipment.

[0152] Among them, the access network equipment belongs to the first operator who has not signed a contract with the terminal equipment, and the service request information is used to request the first operator to provide location services in the absence of a contract.

[0153] In some embodiments, the service demand information includes at least one of the terminal device identification information and the indication information for the demand location service.

[0154] In some embodiments, the access network device may establish a connection with the terminal device before receiving service request information sent by the terminal device.

[0155] Among them, the first operator is the operator identified by the terminal device that can provide location services for the current location of the terminal device.

[0156] In some embodiments, the number of operators capable of providing location services for the current location of the terminal device is multiple.

[0157] In some embodiments, the first operator is determined based on location service information from multiple operators.

[0158] In some embodiments, location service information includes at least one of the following: location method support, location performance, location-related signal parameters, network quality, security information, and operator preset priorities.

[0159] In some embodiments, before establishing a connection with the terminal device, the access network device may also periodically broadcast the location service capability information of the first operator.

[0160] Among them, the location service capability information is used to determine whether the first operator is an operator that can provide location services for the current location of the terminal device.

[0161] S302. Based on the service demand information, send location service instruction information to the terminal device.

[0162] Among them, the location service indication information is used to indicate that the access network equipment can provide location services for the terminal equipment.

[0163] S303, Receive location request information sent by the terminal device.

[0164] In some embodiments, the location request information includes at least one of the following:

[0165] The terminal device's identification information, the relevant information of the detection reference signal, the identification information of the application used for positioning, the service type information, the terminal device's reference location information, and the terminal device's expected positioning accuracy information.

[0166] S304. Perform positioning measurements on the terminal device to obtain its positioning information.

[0167] In some embodiments, the location information includes at least one of the following:

[0168] The terminal device's identification information, location coordinates, positioning accuracy, positioning technology, moving speed, moving direction, and environmental perception information.

[0169] In some embodiments, the access network device performs positioning measurements on the terminal device to obtain the positioning measurement results of the terminal device; based on the positioning measurement results, the positioning information of the terminal device is determined through the positioning server of the first operator.

[0170] In some embodiments, the access network device provides location information to the terminal through a location service interface provided by the first operator.

[0171] In some embodiments, the access network device also sends the terminal's location information to the application used for location, and the application used for location also provides location information of other terminal devices.

[0172] Furthermore, for a detailed description of steps S301-S304, please refer to the relevant descriptions of steps S101-S104 and steps S201-S202 above, which will not be repeated here.

[0173] Based on the above embodiments, access network equipment can provide location services to unsigned terminal devices, thereby separating the location service itself from core network identity authentication. This allows for the provision of location services without core network registration and authentication, meaning network operators can provide location services to unsigned terminals. This expands the scope of the operator's location service, enabling terminal devices outside the service area of ​​signed operators to obtain location services, thus improving the availability of location services for terminal devices.
