Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0233] In some embodiments, "For ranging or sidelink (SL) positioning service disclosure (or publication) over PC5, SL positioning client UE authorization is triggered by the reference or target UE during PC5 link establishment. For UEs supporting Proximity Service (ProSe), the authorization may be performed by the network via the SL Positioning Key Management Function (SLPKMF), or by the reference or target UE if the authorization information is available in the UE.

[0234] In some embodiments, for UE-only operation or before triggering a Sidelink-Mobile Originated-Location Request (SL-MO-LR) for network-based operation, UE1 receiving a ranging or SL positioning request shall send a supplementary ranging and sidelink positioning protocol (RSPP) signaling message to UE2...UEn to trigger a privacy check (or privacy verification) for ranging or SL positioning service disclosure through PC5. The supplementary RSPP message shall include the user information ID of the client UE received by UE1 from the client UE. UE1 and UE2..UEn shall perform a UE privacy check to determine whether their location-related information can be disclosed to the client UE."

[0235] In some embodiments, the designated UE (UE1) that receives the SL positioning service request selects the SL positioning server UE after performing an authorization check for service disclosure on the client UE, and forwards the service request to the server UE for ranging or SL positioning operations. In fact, after receiving the service request from UE1, the server UE needs to obtain SL positioning information from the target or reference UE involved to calculate the final SL positioning result of the client UE. However, the privacy check is only performed on the client UE, and there is no longer a UE privacy check for the server UE. This means that the following risk still exists: without the permission of the target or reference UE, the privacy of the target or reference UE involved may be exposed to the server UE.

[0236] Therefore, it is necessary to study how to protect the privacy of the target or reference UE involved in the process of disclosing the SL positioning service to the client terminal for the server UE. In the related art, there is no mechanism for protecting the privacy of the target or reference UE for the server UE in the process of disclosing the SL positioning service to the client terminal.

[0237] Figure 2aFIG. 1 is an interactive diagram of a communication method according to an embodiment of the present disclosure. Figure 2a As shown, the embodiment of the present disclosure relates to a communication method, which is used in a communication system 100. The method includes:

[0238] Step S2101: The fourth terminal sends first information to the first terminal.

[0239] In some embodiments, the first terminal receives first information sent by the fourth terminal.

[0240] In some embodiments, when the fourth terminal needs to perform the SL positioning service, the first information is sent to the first terminal.

[0241] In some embodiments, the fourth terminal is a client terminal.

[0242] In some embodiments, the first information is used to request the SL positioning service.

[0243] It should be noted that the SL positioning service may also be referred to as a ranging service, or as a ranging or SL positioning (Ranging / SL positioning) service.

[0244] Step S2102: The first terminal determines the third terminal.

[0245] In some embodiments, the first terminal may determine (or select) the third terminal for the first time or repeatedly determine (or reselect) the third terminal. For example, after first determining that the third terminal to be verified cannot serve as the server terminal, the first terminal may re-determine a third terminal that can serve as the server terminal.

[0246] In some embodiments, the first terminal determines the third terminal from at least the first terminal and / or the second terminal based on the second information.

[0247] In some embodiments, the second information is at least used to indicate that the first terminal and / or the second terminal supports or does not support the capability of serving as a server terminal.

[0248] In some embodiments, the first terminal determines the third terminal from at least the first terminal, the second terminal, and / or the fifth terminal based on the second information. The fifth terminal may be an additional terminal other than the first terminal, the second terminal, the third terminal, and the fourth terminal.

[0249] In some embodiments, the second information is at least used to indicate that the first terminal, the second terminal and / or the fifth terminal supports or does not support the capability of serving as a third terminal.

[0250] In some embodiments, the first terminal determines that the server terminal is reselected and the number of times the server terminal is reselected is less than a quantity threshold, thereby determining the third terminal. In some embodiments, the first terminal determines that the server terminal is reselected and the number of times the server terminal is reselected is less than a quantity threshold based on the first rule information, thereby determining the third terminal.

[0251] In some embodiments, the first terminal determines that the third terminal needs to be reselected and the total number of times the third terminal has been reselected is less than a quantity threshold, and determines the third terminal to be reselected.

[0252] In some embodiments, the first terminal determines that the first result indicates that the privacy verification of the SL positioning service performed by the first terminal and / or at least one of the second terminals for the third terminal has failed, and determines to reselect the server terminal.

[0253] In some embodiments, the first terminal determines that the first result indicates that the privacy verification of the SL positioning service performed by the first terminal and / or at least one of the second terminals for the third terminal has failed, and determines that the third terminal needs to be reselected.

[0254] Step S2103: The first terminal sends third information to the second terminal.

[0255] In some embodiments, the second terminal receives third information sent by the first terminal.

[0256] In some embodiments, the first terminal may send the third information to at least two second terminals.

[0257] In some embodiments, the third information is used to trigger privacy verification of the SL positioning service for the third terminal.

[0258] In some embodiments, privacy verification can also be understood as a privacy check, which is used to determine whether the result information of the SL positioning service can be disclosed to a specific object, which is not limited in this disclosure.

[0259] Exemplarily, a UE (UE-1, i.e., the first terminal) that receives a service request (corresponding to the first information) from a SL positioning client UE (corresponding to the fourth terminal) selects a server UE (i.e., the third terminal) to be verified before triggering UE privacy verification. After selecting the server UE, UE-1 triggers a UE privacy check by sending user information of the client UE and the server UE to n target or reference UEs (corresponding to the second terminal).

[0260] In some embodiments, based on the first rule information, the first terminal repeatedly sends the third information to the second terminal.

[0261] In some embodiments, based on the first rule information, the third information is repeatedly sent to the second terminal.

[0262] In some embodiments, the first rule information includes information for indicating repeated triggering of execution of the SL positioning service for the third terminal.

[0263] In some embodiments, the second terminal is a terminal that has fed back a first privacy verification result, and the first privacy verification result indicates that the client terminal has passed the privacy verification.

[0264] In some embodiments, the second terminal is a terminal that has fed back a first privacy verification result, and the first privacy verification result indicates that the fourth terminal has passed the privacy verification.

[0265] In some embodiments, the first terminal determines that the privacy verification of the first terminal for the client terminal has passed, and sends the third information to the second terminal.

[0266] In some embodiments, the first terminal determines that the privacy verification of the first terminal for the fourth terminal has passed, and sends the third information to the second terminal.

[0267] It should be noted that the first terminal determines that the privacy verification of the first terminal for the client terminal has failed, and refuses to accept the SL positioning service.

[0268] In some embodiments, the first terminal determines that the privacy verification of the first terminal for the fourth terminal has failed, and refuses to accept the SL positioning service.

[0269] In some embodiments, the third information includes at least one of the following:

[0270] user information of the first terminal;

[0271] User information of the client terminal;

[0272] User information of the server terminal;

[0273] Service identifier.

[0274] In some embodiments, the first terminal is determined to be a server terminal, and user information of the first terminal is the same as user information of the server terminal.

[0275] In some embodiments, the third information includes at least one of the following:

[0276] user information of the first terminal;

[0277] User information of the fourth terminal;

[0278] User information of the third terminal;

[0279] Service identifier.

[0280] In some embodiments, the first terminal is determined to be a server terminal, and user information of the first terminal is the same as user information of the third terminal.

[0281] Step S2104: The second terminal performs privacy verification of the SL positioning service.

[0282] In some embodiments, after receiving the third information, the second terminal performs privacy verification of the SL positioning service for the third terminal based on the second rule information.

[0283] In some embodiments, if the privacy verification passes, the second terminal may disclose or publish the positioning result information to the third terminal; or, if the privacy verification fails, the second terminal may not disclose or publish the positioning result information to the third terminal.

[0284] Step S2105: The second terminal sends fourth information to the first terminal.

[0285] In some embodiments, the first terminal receives fourth information sent by the second terminal.

[0286] In some embodiments, the fourth information includes the first result, and the first result includes a result obtained by the second terminal performing privacy verification of the SL positioning service on the third terminal.

[0287] Step S2106: The first terminal determines whether to accept or reject the SL positioning service based on the first result.

[0288] It can be understood that accepting or rejecting the SL positioning service can also be accepting or rejecting the SL positioning service request, for example, it can be accepting or rejecting the first information of the fourth terminal.

[0289] In some embodiments, the first result is a result obtained by the first terminal and / or at least one second terminal performing privacy verification of the SL positioning service on the third terminal.

[0290] In some embodiments, the first terminal, the second terminal and the third terminal are terminals for performing SL positioning services.

[0291] In some embodiments, the second terminal is a target terminal or a reference terminal, and the third terminal is a server terminal (or a server terminal to be verified).

[0292] In some embodiments, the acceptance or rejection of the SL positioning service is determined based on the first result and / or first rule information included in the fourth information.

[0293] In some embodiments, the first rule information is a rule for determining whether to perform SL positioning service based on the first result.

[0294] In some embodiments, the first rule information is used to indicate at least one of the following:

[0295] All N terminals need to participate in SL positioning and any of the N terminals is not allowed to disclose information to a fourth terminal, and the first terminal refuses the SL positioning service;

[0296] All N terminals need to participate in SL positioning, the N terminals are allowed to disclose information to the fourth terminal, and any terminal among the N terminals is not allowed to disclose information to the third terminal, and the first terminal reselects a third terminal (or a server terminal);

[0297] If all N terminals need to participate in SL positioning, N terminals allow information disclosure to the fourth terminal, any of the N terminals does not allow information disclosure to the third terminal, and the number of times the third terminal (or server terminal) has been reselected reaches the maximum, the first terminal refuses the SL positioning service;

[0298] Allowing M terminals among the N terminals not to participate in SL positioning and any terminal other than the M terminals among the N terminals is allowed to disclose information to the third terminal, and the first terminal accepts the SL positioning service;

[0299] Allowing M terminals out of N terminals not to participate in SL positioning and any terminal other than the M terminals out of the N terminals is not allowed to disclose information to the third terminal, and the first terminal reselects a server terminal; allowing M terminals out of N terminals not to participate in SL positioning and any terminal other than the M terminals out of the N terminals is not allowed to disclose information to the third terminal, and the first terminal refuses the SL positioning service;

[0300] M terminals out of N terminals are allowed not to participate in SL positioning, any terminal other than M terminals out of N terminals is not allowed to disclose information to the third terminal, and the number of times the third terminal (or server terminal) is reselected reaches the maximum value, and the first terminal refuses the SL positioning service;

[0301] The maximum number of times the third terminal (or server terminal) can be reselected;

[0302] The N terminals include the first terminal and / or the second terminal, N is an integer greater than 1, and M is an integer, 1<M<N.

[0303] Exemplarily, when the first terminal receives the privacy check results (corresponding to the fourth information) from n target or reference UEs (corresponding to the second terminal), UE-1 (the first terminal) determines how to accept or reject the service request (corresponding to the first information) based on the local rules (corresponding to the first rule information) from, for example, the ranging or SL positioning application on UE-1.

[0304] For example, all n UEs (corresponding to the second terminal) must participate in ranging or SL positioning. If any of the n UEs does not allow the SL positioning service result to be disclosed to the client UE (corresponding to the first terminal), the service request (corresponding to the first information) is rejected. If all n UEs allow disclosure to the client UE, but any of the n UEs does not allow disclosure to the server UE, UE-1 will reselect the server UE.

[0305] For example, a portion (eg, m) of the n UEs (corresponding to the first terminal) is allowed to be excluded from ranging or SL positioning due to privacy issues. If any of the nm UEs does not allow disclosure to the server UE, UE-1 will reselect the server UE.

[0306] For example, if the client UE allows a part of n UEs to be excluded from ranging or SL positioning, when the client UE selects UE-1 to receive the ranging or SL positioning service request, it must select the UE that cannot be excluded from ranging or SL positioning to disclose the SL positioning results through PC5.

[0307] In some embodiments, the first rule information is provided by an SL positioning application running on the first terminal indicated by a service identifier of the fourth terminal (or client terminal) or the first rule information is included in the subscription information.

[0308] Exemplarily, the local rules of UE-1 (corresponding to the first rule information) can be provided by a ranging or SL positioning application on UE-1 (corresponding to the first terminal) identified by a service identifier from the client UE (corresponding to the fourth terminal), or if the rules are included in the privacy profile as part of the subscription data when UE-1 subscribes to the ranging or SL positioning service, it can be provided by a network function (for example, Unified Data Management (UDM), Policy Control Function (PCF) or Location Management Function (LMF)).

[0309] Step S2107: the first terminal sends fifth information to the third terminal selected as the server terminal.

[0310] In some embodiments, the third terminal receives the fifth information sent by the first terminal.

[0311] In some embodiments, upon determining to accept the SL positioning service, the first terminal sends fifth information to the third terminal selected as the server terminal.

[0312] In some embodiments, the fifth information is used to request SL positioning service.

[0313] In some embodiments, the fifth information is used to indicate at least one of the following:

[0314] service identifier;

[0315] User information of the fourth terminal;

[0316] Information of the second terminal returning a first privacy verification result for the first terminal, the fourth terminal (client terminal) and / or the third terminal (server terminal), wherein the first privacy verification result indicates that the privacy verification has been passed.

[0317] Step S2108: The first terminal sends sixth information to the fourth terminal.

[0318] In some embodiments, the fourth terminal receives the sixth information sent by the first terminal.

[0319] In some embodiments, the first terminal accepts the SL positioning service, and the sixth information is used to indicate: accepting the request of the fourth terminal to perform the SL positioning service and / or obtaining the SL positioning service result.

[0320] In some embodiments, the first terminal rejects the SL positioning service, and the sixth information is used to indicate: rejecting the request of the fourth terminal to perform the SL positioning service.

[0321] In some embodiments, the sixth information is used to indicate the rejection of the request of the fourth terminal to perform the SL positioning service; the sixth information is also used to indicate the reason for rejecting the request of the fourth terminal to perform the SL positioning service.

[0322] In some embodiments, the reason includes at least one of the following: the request of the fourth terminal is rejected; the request of the fourth terminal is rejected by the second terminal; the third terminal (server terminal) selection fails; there is no third terminal (server terminal).

[0323] In some embodiments, the term "information" can be interchangeable with terms such as "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", and "data".

[0324] In some embodiments, the term "send" can be interchanged with terms such as "transmit", "report", and "transmit".

[0439] Step S7101: The first terminal sends third information to the second terminal.

[0440] In some embodiments, the third information is used to trigger privacy verification of the SL positioning service for a third terminal, and the third terminal is a server terminal to be verified.

[0441] Optional implementations of step S7101 can be found in Figure 2a Optional implementation of step S2103 and Figure 2a Other related parts in the embodiments involved will not be described in detail here.

[0442] In some embodiments, the above method may include the methods of the above-mentioned communication system side, first terminal side, second terminal side, third terminal side, fourth terminal side, etc., which will not be repeated here.

[0443] In order to better understand the embodiments of the present disclosure, the technical solutions of the present disclosure are further described below through some exemplary embodiments:

[0444] See Figure 8a , provides a communication method, the method comprising:

[0445] Step S8101: Sending a positioning service request (corresponding to the first information). The client UE (corresponding to the fourth terminal) selects the UE (UE-1) to receive the ranging / SL positioning service request, and publishes the SL positioning results through PC5. The service request includes a service identifier (or service identifier), information about the client UE (corresponding to the user information of the fourth terminal), information about UE-2 / .. / UE-n (corresponding to the user information of the second terminal), etc.

[0446] Step S8102: Perform privacy check (or privacy verification). When receiving a service request (corresponding to the first information) from the client UE and selecting UE-only operation, UE-1 performs a privacy check as follows:

[0447] i) Checking whether the SL positioning result is allowed to be disclosed to the client UE according to its privacy profile (or privacy configuration file);

[0448] ii) Checking whether the SL positioning measurement data or results are allowed to be disclosed to UE-2 / .. / UE-n (corresponding to the second terminal) by comparing its privacy profile (or privacy configuration file).

[0449] Step S8103: Perform terminal discovery. UE-1 discovers UE-2 / ... / UE-n, establishes a PC5 link with UE-2 / ... / UE-n, and obtains the capabilities of UE-2 / ... / UE-n.

[0450] Step S8104: Based on the capabilities of UEs, UE-1 selects a server UE (server UE-x, corresponding to the third terminal). Server UE-x can be UE-1 itself, or a UE in UE-2 / ... / UE-n, or an additional UE (corresponding to the fifth terminal).

[0451] Step S8105: Send supplemental ranging and sidelink positioning protocol (RSPP) signaling (corresponding to the third information). UE-1 sends supplemental RSPP signaling messages to UE-2 / .. / UE-n for privacy checks. This message includes information about the client UE (corresponding to the user information of the fourth terminal), information about UE-1 (corresponding to the user information of the first terminal), and information about the server UE-x (corresponding to the user information of the third terminal). If UE-1 is selected as the server UE, the information about UE-1 (corresponding to the user information of the first terminal) and the information about the server UE-x (corresponding to the user information of the third terminal) are the same.

[0452] Step S8106: Perform privacy check. Each of UE-2 / .. / UE-n checks its own privacy profile (or privacy configuration file) as follows:

[0453] Check whether it allows SL positioning with UE-1,

[0454] Check whether it is allowed to expose the SL positioning results to the client UE,

[0455] Check whether it is allowed to expose its SL location information to the server UE-x.

[0456] Step S8107: Receive the privacy check result (corresponding to the fourth information). UE-1 receives the privacy check results from UE-2 / .. / UE-n respectively.

[0457] Step S8108: Execute processing operations based on the privacy check result.

[0458] In some embodiments, if the local rule (corresponding to the first rule information) indicates that all n UEs must participate in ranging / SL positioning (default rule), then when UE-1 receives a negative privacy check result for the client UE from any one of UE-2 / .. / UE-n (i.e., fails the privacy check), UE-1 may have rejected the service request (corresponding to the rejection of the first information).

[0459] If local rules indicate that m out of n UEs can be excluded from ranging / SL positioning, UE-1 should keep receiving privacy check results from UE-2 / .. / UE-n until it can make a decision based on the local rules.

[0460] In some embodiments, UE-1 performs a first round of checking according to the rules to determine whether the privacy check result for the client UE and UE-1 is yes (ie, the privacy check is passed). If not, UE-1 proceeds to step S8109a.

[0461] If the first round of checks passes, UE-1 then performs a second round of checks based on local rules to determine whether the privacy check result of the server UE-x is positive (i.e., it passes the privacy check). If not, UE-1 proceeds to step S8109b or step S8114a. If yes, UE-1 proceeds to step S8114b.

[0462] Step S8109a: UE-1 responds to the client UE with a rejection message (corresponding to the sixth message). The reason for the failure may be included in the rejection message, for example, the request to disclose the SL positioning result to the client UE was rejected, disclosure of the SL positioning result was rejected by UE-i, disclosure of the SL positioning result was rejected by a rule, etc. Here, UE-i can be at least one of UE-2 to UE-n.

[0463] Step S8109b: If the upper limit of server UE reselection (corresponding to the quantity threshold) has not been reached according to the local rule, UE-1 reselects server UE-y (corresponding to the third terminal).

[0464] Step S8110: UE-1 again sends a supplementary RSPP signaling message to a portion of UE-2 / ... / UE-n for privacy checking. The portion of UE-2 / ... / UE-n is the UE that returned a positive privacy check result for the client UE and UE-1. This message includes information about the server UE-y, among other things.

[0465] Step S8111: Perform privacy check. A portion of UE-2 / .. / UE-n checks against its own privacy profile as follows:

[0466] - Check whether it allows its SL location information to be disclosed to the server UE-y

[0467] Step S8112: UE-1 receives privacy check results (corresponding to the fourth information) from part of UE-2 / .. / UE-n respectively.

[0468] Step S8113: Execute processing based on the privacy check result. UE-1 checks whether the privacy check result for server UE-y is positive (or passed) according to the local rule (corresponding to the second rule information). If not (failed) and the upper limit (i.e., the maximum number of server UE reselections) has been reached, UE-1 proceeds to step S8114a. If yes, UE-1 proceeds to step S8114b.

[0469] Step S8114a: UE-1 responds to the client UE with a rejection message (corresponding to the sixth information). The cause of the failure may be, for example, failure to select the third terminal (server terminal), the absence of the third terminal (server terminal), etc.

[0470] Step S8114b: UE-1 sends a supplementary RSPP signaling message (corresponding to the fifth information) to the selected third terminal (i.e., server UE-y). The message includes a ranging / SL positioning service request from the client UE. The service request includes a service identifier, information about the client UE (corresponding to the user information of the fourth terminal), and information about UEs among UE-2 / .. / UE-n that return a positive privacy check result for UE-1, the client UE, or the server UE (corresponding to the user information of the second terminal).

[0471] Step S8115: SL positioning operations, data transmission and / or result calculation are performed between the server UE, UE-1 and the UEs among UE-2 / .. / UE-n that return a positive privacy check result.

[0472] Step S8116: UE-1 responds to the client UE with the SL positioning result (corresponding to the sixth information). UE-1 may also inform the client UE of the actual UEs involved in the ranging / SL positioning operation by indicating the involved UEs or the uninvolved UEs.

For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods.
