Description

Technical Field

[0001] This application belongs to the field of wireless communication technology, specifically relating to a location verification enhancement method, apparatus, communication device, and readable storage medium. Background Technology

[0002] In non-terrestrial networks (NTNs), terminals possess location capabilities, meaning they are aware of their own location information by default. However, unverified terminal location information is unreliable, or some terminals may be illegitimate, with their location information being false or incorrect. Therefore, network-side verification of terminal location information is necessary.

[0003] To ensure the reliability of terminal location information, the network side typically needs to continuously verify the terminal location information. This will result in significant signaling overhead. Summary of the Invention

[0004] The purpose of this application is to provide a location verification enhancement method, apparatus, communication device, and readable storage medium to solve the problem of large signaling overhead caused by current terminal location information verification methods.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] Firstly, a location verification enhancement method is provided, including:

[0007] The terminal receives configuration information from the network-side device, wherein the configuration information is used to configure the validity period information of the terminal's verified location.

[0008] Secondly, a location verification enhancement method is provided, including:

[0009] The network-side device sends configuration information to the terminal, wherein the configuration information is used to configure the validity period information of the terminal's verified location.

[0010] Thirdly, a location verification enhancement device is provided, applied to a terminal, including:

[0011] The first receiving module is used to receive configuration information from the network-side device, wherein the configuration information is used to configure the validity period information of the verified location of the terminal.

[0012] Fourthly, a location verification enhancement device is provided, applied to network-side equipment, including:

[0013] The second sending module is used to send configuration information to the terminal, wherein the configuration information is used to configure the validity period information of the terminal's verified location.

[0014] Fifthly, a communication device is provided, including a processor, a memory, and a program or instructions stored in the memory and executable on the processor, wherein the program or instructions, when executed by the processor, implement the steps of the method described in the first aspect, or the steps of the method described in the second aspect.

[0015] In a sixth aspect, a readable storage medium is provided, on which a program or instructions are stored, which, when executed by a processor, implement the steps of the method described in the first aspect, or the steps of the method described in the second aspect.

[0016] In this embodiment, the terminal can receive configuration information from the network-side device. This configuration information is used to configure the validity period information of the terminal's verified location. Therefore, by configuring the validity period information of the terminal's verified location, the terminal does not need to undergo location verification again within the time corresponding to this validity period information, thereby reducing the latency and signaling overhead caused by repeated verification.

The base station is not limited to specific technical terms.

[0029] Considering the wide coverage of non-terrestrial networks, the large number of terminals, and the long round-trip transmission latency, and the fact that the reliability of a terminal's location does not suddenly decrease after being verified once, and that continuous location verification by the network side would lead to significant latency and signaling overhead, this application proposes a location verification enhancement method. This method configures valid time information for the verified location of the terminal. Thus, the terminal does not need to be re-verified within the time corresponding to this valid time information, thereby reducing the latency and signaling overhead caused by repeated verification.

[0030] Optionally, the scenarios applicable to the embodiments of this application include, but are not limited to, non-terrestrial network (NTN) scenarios. This solution can enhance terminal location verification in non-terrestrial network communication scenarios.

[0031] The location verification enhancement method, apparatus, communication device, and readable storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0032] Please see Figure 2 , Figure 2 This is a flowchart of a location verification enhancement method provided in an embodiment of this application. The method is applied to a terminal, such as... Figure 2 As shown, the method includes the following steps:

[0033] Step 21: The terminal receives configuration information from the network-side device. The configuration information is used to configure the validity period information of the terminal's verified location.

[0034] In this way, by configuring the valid time information of the verified location for the terminal, the terminal does not need to be verified again within the time corresponding to the valid time information, thereby reducing the latency and signaling overhead caused by repeated verification.

[0035] In some embodiments, the terminal may receive configuration information from the network-side device through any of the following: Radio Resource Control (RRC) signaling, Downlink Control Information (DCI), Media Access Control Unit (MAC CE), broadcast messages, multicast messages, etc.

[0036] In this embodiment of the application, the valid time limit and / or token can be configured to set the valid time information of the verified location for the terminal. Optionally, the valid time information may include at least one of the following:

[0037] Validity limitation period; for example, the network-side device configures a validity limitation period for a terminal that has obtained location verification once, during which the terminal does not need to be verified for location again.

[0038] Tokens carrying location validity period attributes; for example, the network-side device configures a token carrying location validity period attributes for a terminal that has obtained location verification once. The location validity period corresponding to this token is, for example, 1 hour, 2 hours, 3 hours, etc. As long as the terminal holds the corresponding token, there is no need to perform location verification again; the corresponding token is discarded after the token held by the terminal expires.

[0039] In this way, by using the configured validity period / token carrying the location validity period attribute, the terminal can know whether its verified location is valid, thereby avoiding repeated verification and achieving the purpose of reducing latency and signaling overhead.

[0040] Optionally, the above-mentioned validity period may take the form of at least one of the following:

[0041] Absolute time length; for example, to determine the validity of a terminal's verified location, the start time is configured as t1 and the end time as t2, meaning that the terminal's verified location is valid within the time interval from t1 to t2.

[0042] Relative time length; for example, to configure a duration for the validity of the terminal's verified location, during which the terminal's verified location is valid;

[0043] Timer; for example, start a timer after a successful verification, and do not need to perform location verification again while the timer is running.

[0044] Optionally, to facilitate configuring the validity period of verified locations for terminals using tokens, tokens carrying location validity period attributes can be categorized based on different levels. For tokens carrying location validity period attributes, different levels of tokens correspond to different location validity periods.

[0045] For example, the correspondence between token level and location validity period can be shown in Table 1 below:

[0046] Table 1

[0047]

[0048] In this embodiment, the location verification process can be triggered based on a terminal request or instruction. The aforementioned location verification enhancement method may further include at least one of the following:

[0049] The terminal sends a first request message, which is used to request the terminal's location to be verified again; for example, the terminal may send the first request message to the base station to request the network to verify the terminal's location again.

[0050] The terminal sends a first indication message, which indicates that the terminal's location validity period meets any of the following: expired, timed out, about to expire, or about to time out, and the network triggers the verification of the terminal's location; for example, the terminal can send the first indication message to the base station to indicate that the terminal's location validity period has expired, timed out, is about to expire, or is about to time out.

[0051] In one implementation, when the configured validity period expires, the terminal location can be re-verified in any of the following ways: 1) The terminal sends a request to the network that it needs to be re-verified; 2) The terminal informs the network that its location validity period has expired, timed out, is about to expire, or is about to time out, and the network side triggers the re-location verification process; 3) The network side directly triggers the location verification process.

[0052] In another implementation, when the token held by the terminal expires and the corresponding token is discarded, the terminal location can be re-verified in any of the following ways: 1) The terminal sends a request to the network that it needs to be re-verified; 2) The terminal informs the network that its location validity period has expired, expired, is about to expire, or is about to expire, and the network side triggers the re-location verification process; 3) The network side directly triggers the location verification process.

[0053] In this embodiment of the application, when the service network changes, such as when a network reselection or switching occurs, the terminal can report its location validity time information after accessing the new network, thereby reducing the need for repeated terminal location verification and reducing the latency and signaling overhead caused by repeated verification.

[0054] Optionally, when the terminal reselects from the first network or switches to the second network, the location verification enhancement method in this embodiment may further include at least one of the following:

[0055] 1) When the satellites of the first network and the satellites of the second network are satellites of the same orbit type, after the terminal accesses the second network, it reports the valid time information of the terminal's verified location, that is, it reports the valid time information of the verified location to the network-side equipment (such as the base station) in the second network.

[0056] In other words, when the satellites used in a new network are of the same orbital type as the previous serving satellites—for example, from Low Earth Orbit (LEO) to LEO, or from Medium Earth Orbit (MEO) to MEO—the terminal can report the valid time information of its verified location after accessing the new network in the case of reselection or handover. This valid time information can be selected as a validity period limit or a token carrying location validity attributes.

[0057] 2) When the satellites of the first network and the satellites of the second network are satellites of different orbit types, after the terminal accesses the second network, it reports the first valid time information, that is, reports the first valid time information to the network-side equipment (such as the base station) in the second network; the first valid time information is determined based on the orbital altitude difference between the satellites of the first network and the satellites of the second network and the valid time information of the terminal's verified position.

[0058] In other words, when the satellites after the network change and the previous serving satellites belong to different orbital types, such as changing from LEO to MEO, or from MEO to LEO, in the case of reselection or handover, the terminal can report the location validity time information calculated based on the orbital altitude difference after accessing the new network. This information may include validity time limits or tokens carrying location validity period attributes.

[0059] Optionally, when changing from a lower orbit satellite to a higher orbit satellite, the valid time limit for the terminal's verified location (e.g., the remaining valid time of the location after the network change) can be extended according to the difference in orbital altitude. The location validity period corresponding to the token can also become longer according to the difference in orbital altitude, that is, the configured token can be replaced with a token with a longer location validity period. For example, if changing from a 600km orbit satellite to a 1200km orbit satellite, that is, the orbital altitude increases by 100%, the remaining valid time of the terminal's verified location can be extended to twice the original time, or the configured token can be replaced with a token with double the location validity period, that is, the location validity period of the replaced token is twice the location validity period of the original token.

[0060] Optionally, when changing from a higher orbit satellite to a lower orbit satellite, the valid time limit for the terminal's verified location (e.g., the remaining valid time of the location after the network change) can be reduced according to the difference in orbital altitude. The location validity period corresponding to the token can also become shorter according to the difference in orbital altitude, that is, the configured token can be replaced with a token with a shorter location validity period. For example, if changing from a 1200km orbit satellite to a 600km orbit satellite, that is, the orbital altitude is reduced by half, the remaining valid time of the terminal's verified location can be reduced to half of the original time, or the configured token can be replaced with a token with half the location validity period, that is, the location validity period of the replaced token is half of the original token's location validity period.

[0061] In this embodiment of the application, in order to ensure the validity of the terminal location, if an abnormal situation occurs, the network side can force the terminal to terminate the current communication process, instruct the terminal to release the validity restriction time or token corresponding to the verified location, and re-trigger the terminal location verification process.

[0062] Optionally, the location verification enhancement method in this embodiment may further include:

[0063] The terminal receives a second indication message from the network-side device. This second indication message is used for at least one of the following: instructing the terminal to terminate the communication process, or instructing the release of the valid time information of the terminal's verified location. Thus, by using the issued second indication message, the terminal location verification process can be re-triggered, thereby ensuring the validity of the terminal's location.

[0064] In some embodiments, the location validity time limit or token configured by the network is still valid, but if the network-side device finds that the timing advance (TA) deviation of the terminal compensation is too large and exceeds a certain threshold, it can instruct the terminal to terminate the current communication process, instruct the terminal to release the validity time limit or token corresponding to the verified location, and re-trigger the terminal location verification process.

[0065] Optionally, the terminal may receive the second indication information from the network-side device through any of the following methods:

[0066] Radio Resource Control (RRC) signaling; this RRC signaling can use existing or newly designed RRC signaling.

[0067] Downlink Control Information (DCI); This DCI can be an existing or newly designed DCI.

[0068] Medium Access Control Element (MAC CE); this MAC CE can be an existing or newly designed MAC CE;

[0069] Broadcast message; this broadcast message can be an existing or newly designed broadcast message;

[0070] Multicast message.

[0071] In one implementation, the format of the MAC CE received by the terminal can be as follows: Figure 3A As shown, TC (Terminate all communications) instructs the UE to terminate all communication processes, and RT (Release Token) instructs the UE to release the token it holds that carries the location validity period attribute. For example, TC is 1 bit and RT is 1 bit.

[0072] In another implementation, the format of the MAC CE received by the terminal can be as follows: Figure 3BAs shown, TC (Terminate all communications) instructs the UE to terminate all communication processes, and TS (Timer Stop) instructs the UE to stop the currently running location-validated timer. For example, TC is 1 bit and TS is 1 bit.

[0073] Please see Figure 4 , Figure 4 This is a flowchart of a location verification enhancement method provided in an embodiment of this application. This method is applied to network-side devices, such as base stations. Figure 4 As shown, the method includes the following steps:

[0074] Step 41: The network-side device sends configuration information to the terminal, which is used to configure the validity period information of the terminal's verified location.

[0075] In this way, by configuring the valid time information of the verified location for the terminal, the terminal does not need to be verified again within the time corresponding to the valid time information, thereby reducing the latency and signaling overhead caused by repeated verification.

[0076] In some embodiments, the network-side device may send configuration information to the terminal through any of the following: Radio Resource Control (RRC) signaling, Downlink Control Information (DCI), Media Access Control (MAC) CE, broadcast messages, multicast messages, etc.

[0077] Optionally, the valid time information may include at least one of the following:

[0078] Validity limitation period; for example, the network-side device configures a validity limitation period for a terminal that has obtained location verification once, during which the terminal does not need to be verified for location again.

[0079] Tokens carrying location validity period attributes; for example, the network-side device configures a token carrying location validity period attributes for a terminal that has obtained location verification once. The location validity period corresponding to this token is, for example, 1 hour, 2 hours, 3 hours, etc. As long as the terminal holds the corresponding token, there is no need to perform location verification again; the corresponding token is discarded after the token held by the terminal expires.

[0080] In this way, by using the configured validity period / token carrying the location validity period attribute, the terminal can know whether its verified location is valid, thereby avoiding repeated verification and achieving the purpose of reducing latency and signaling overhead.

[0081] Optionally, the above-mentioned validity period may take the form of at least one of the following:

[0082] Absolute time length; for example, to determine the validity of a terminal's verified location, the start time is configured as t1 and the end time as t2, meaning that the terminal's verified location is valid within the time interval from t1 to t2.

[0083] Relative time length; for example, to configure a duration for the validity of the terminal's verified location, during which the terminal's verified location is valid;

[0084] Timer; for example, start a timer after a successful verification, and do not need to perform location verification again while the timer is running.

[0085] Optionally, to facilitate configuring the validity period of verified locations for terminals using tokens, tokens carrying location validity period attributes can be categorized based on different levels. For tokens carrying location validity period attributes, different levels of tokens correspond to different location validity periods.

[0086] In this embodiment, the location verification process can be triggered based on a terminal request or instruction. The aforementioned location verification enhancement method may further include at least one of the following:

[0087] The location verification process is triggered directly on the network side.

[0088] The network-side device receives a first request message sent by the terminal, which is used to request the terminal's location to be verified again; for example, the terminal can send a first request message to the base station to request the network to verify the terminal's location again.

[0089] The network-side device receives the first indication information sent by the terminal and triggers the verification of the terminal's location; the first indication information is used to indicate that the terminal's location validity period meets any of the following: expired, timed out, about to expire, or about to time out.

[0090] In this embodiment of the application, when the serving network changes, such as when a network switch occurs, the source network side device (such as the source base station) and the target network side device (such as the target base station) can directly exchange and switch the terminal's valid location time information, thereby reducing repeated verification of the terminal's location and reducing the latency and signaling overhead caused by repeated verification.

[0091] Optionally, when the network-side device is in a third network and the terminal switches from the third network to a fourth network, the location verification enhancement method in this embodiment may further include at least one of the following:

[0092] 1) When the satellites of the third network and the satellites of the fourth network are satellites of the same orbit type, the network-side device sends the valid time information of the terminal's verified location to the network-side device in the fourth network.

[0093] In other words, when the satellite after a network change and the previous serving satellite belong to the same orbital type, such as changing from LEO to LEO or from MEO to MEO, for handover situations, the source network-side equipment (such as the source base station) and the target network-side equipment (such as the target base station) directly exchange the valid time information of the verified location of the handover terminal. For example, this valid time information can be selected as a validity restriction time or a token carrying location validity attributes.

[0094] 2) When the satellites of the third network and the satellites of the fourth network belong to different orbital types, the network-side device sends second valid time information to the network-side device in the fourth network. The second valid time information is determined based on the orbital altitude difference between the satellites of the third network and the satellites of the fourth network and the valid time information of the terminal's verified position.

[0095] In other words, when the satellite after the network change and the previous serving satellite belong to different orbit types, such as changing from LEO to MEO, or from MEO to LEO, for the handover situation, the source network side equipment (such as the source base station) and the target network side equipment (such as the target base station) directly exchange the effective time information of the position calculated based on the difference in orbital altitude.

[0096] Optionally, when changing from a lower orbit satellite to a higher orbit satellite, the valid time limit for the terminal's verified location (e.g., the remaining valid time of the location after the network change) can be extended according to the difference in orbital altitude. The location validity period corresponding to the token can also become longer according to the difference in orbital altitude, that is, the configured token can be replaced with a token with a longer location validity period. For example, if changing from a 600km orbit satellite to a 1200km orbit satellite, that is, the orbital altitude increases by 100%, the remaining valid time of the terminal's verified location can be extended to twice the original time, or the configured token can be replaced with a token with double the location validity period, that is, the location validity period of the replaced token is twice the location validity period of the original token.

[0097] Optionally, when changing from a higher orbit satellite to a lower orbit satellite, the valid time limit for the terminal's verified location (e.g., the remaining valid time of the location after the network change) can be reduced according to the difference in orbital altitude. The location validity period corresponding to the token can also become shorter according to the difference in orbital altitude, that is, the configured token can be replaced with a token with a shorter location validity period. For example, if changing from a 1200km orbit satellite to a 600km orbit satellite, that is, the orbital altitude is reduced by half, the remaining valid time of the terminal's verified location can be reduced to half of the original time, or the configured token can be replaced with a token with half the location validity period, that is, the location validity period of the replaced token is half of the original token's location validity period.

[0098] In this embodiment of the application, in order to ensure the validity of the terminal location, if an abnormal situation occurs, the network side can force the terminal to terminate the current communication process, instruct the terminal to release the validity restriction time or token corresponding to the verified location, and re-trigger the terminal location verification process.

[0099] Optionally, the location verification enhancement method in this embodiment may further include:

[0100] The network-side device sends a second indication message to the terminal. This second indication message serves at least one of the following purposes: instructing the terminal to terminate the communication process, or instructing the release of the valid time information of the terminal's verified location. By using this second indication message, the terminal location verification process can be re-triggered, thereby ensuring the validity of the terminal's location.

[0101] Optionally, the terminal may receive the second indication information from the network-side device through any of the following: RRC signaling, DCI, MAC CE, broadcast message, multicast message, etc.

[0116] The reporting module is used to perform any of the following when the terminal reselects from the first network or switches to the second network:

[0117] When the satellites of the first network and the satellites of the second network are satellites of the same orbit type, after accessing the second network, the valid time information of the verified location of the terminal is reported, that is, the valid time information of the verified location is reported to the network-side equipment (such as the base station) in the second network.

[0118] When the satellites of the first network and the satellites of the second network belong to different orbital types, after accessing the second network, the first valid time information is reported, that is, the first valid time information is reported to the network-side equipment (such as base stations) in the second network; the first valid time information is determined based on the orbital altitude difference between the satellites of the first network and the satellites of the second network and the valid time information of the verified position of the terminal.
