Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technologies, and in particular, to an information processing method, apparatus, communication device, and storage medium, but is not limited thereto.

Background Art

[0002] In related technologies, a third-party user equipment (UE) obtains ranging / sidelink (SL) positioning results via an assistant UE. The assistant UE uses a direct connection discovery process to disclose its ranging / SL positioning service to the third-party UE. The third-party UE does not need to have a ranging / SL positioning function and can perform discovery between UEs and selection of the assistant UE based on the assistant's ranging information in the discovery message broadcast by the assistant UE.

[0003] After discovery between the third-party UE and the assistant UE, the third-party UE calls the ranging / SL positioning service of the assistant UE to obtain the ranging result between UE1 and UE2. The assistant UE performs a ranging process for UE1 and UE2 respectively, and calculates the ranging result between UE1 and UE2 based on the ranging result between UE1 and itself and the ranging result between UE2 and itself. The current security mechanism can only guarantee to permit the third-party UE to call the ranging service with the assistant UE. However, there is no existing method for the assistant UE to check whether the third-party UE is permitted to request the ranging result of the target UE (such as UE1 or UE2). Therefore, the current security mechanism cannot prevent a suspicious third-party UE from requesting the ranging results of the target UEs (for example, UE1 and UE2).

[0075] To facilitate understanding for those skilled in the art, the embodiments of this disclosure enumerate several embodiments in order to clearly illustrate the technical solutions in the embodiments of this disclosure. Obviously, those skilled in the art will understand that several embodiments provided by the embodiments of this disclosure may be performed separately, in conjunction with the methods of other embodiments in the embodiments of this disclosure, or performed separately or in combination and then in conjunction with some embodiments in other relevant technologies. The embodiments of this disclosure are not limited in this respect.

[0076] In embodiments of this disclosure, where multiple implementers are involved and one implementer transmits a transmission to another implementer, this may mean that one implementer transmits the transmission directly to the other implementer, or that one implementer transmits the transmission to the other implementer via any other device. Embodiments of this disclosure are not limited in this respect.

[0077] To better understand the technical solutions described in any embodiment of this disclosure, we will first provide some explanation of the relevant technology.

[0078] As shown in Figure 2, a third-party UE can perform mutual discovery with the assistant UE based on the SL and request the assistant UE to assist in measuring the distance between UE1 and UE2. Generally, since mutual discovery is completed between the third-party UE and the assistant UE and the SL is established, the third-party UE is a trusted UE by the assistant UE. If the assistant UE receives a request from the third-party UE to assist in measuring the distance between UE1 and UE2, it also needs to confirm whether or not to allow the third-party UE to measure the distance between UE1 and UE2.

[0079] In some application scenarios, the Assistant UE broadcasts announcement information containing Assistant UE information, role instructions (i.e., "Assistant UE"), a ranging service code, and ranging exposure information. The ranging exposure information includes a list of target UE information. Using this list, the Assistant UE can perform ranging / SL location determination. A third-party UE monitors the announcement information and discovers the Assistant UE based on the ranging exposure information it receives. If the target UE for which the third-party UE seeks ranging results is included in the list of target UE information in the ranging exposure information, the third-party UE selects the discovered Assistant UE and then establishes a secure PC5 connection with the Assistant UE.

[0080] Assuming that the security establishment process for 5G ProSe direction communication, as defined in related technologies, may be reused for PC5 direct communication ranging, current security mechanisms can only ensure that a third-party UE is permitted to invoke ranging services with the assistant UE. However, according to the current specifications, there is no existing way for the assistant UE to check whether a third-party UE is permitted to request ranging results for the target UE. Therefore, if a malfunctioning third-party UE, which is not permitted to request ranging results for UE1 and UE2, responds to a broadcast message from the assistant UE notifying UE1 and UE2, the third-party UE can establish a PC5 connection with the assistant UE. Even if the third-party UE is authenticated and authorized during the establishment of the PC5 connection, current security mechanisms cannot prevent a malfunctioning third-party UE from requesting ranging results for UE1 / UE2.

[0081] As shown in Figure 3, one embodiment of the present disclosure provides an information processing method performed by a first UE, which includes: Step S31: Send the first request information to the second UE, the first request information comprising the first identification information of the first UE and the second identification information of the second UE, the first request information used to request the establishment of direct connection communication, the first request information further comprising the third identification information of the third UE for requesting ranging results and a ranging service code for instructing to request ranging services.

[0082] Here, the first UE may be a third-party UE, the second UE may be an assistant UE, and the third UE may be the UE under test or the target UE. The assistant UE may be any UE capable of performing ranging / SL positioning with the third UE (such as UE1 and UE2 in the above embodiment). For example, the assistant UE may find and measure UE1 and UE2 based on the SL. The third-party UE may be any UE other than the assistant UE and the UE under test.

[0083] Here, the first UE, the second UE, and the third UE may all be various mobile or fixed terminals. For example, the UE may be, but is not limited to, a mobile phone, computer, server, wearable device, vehicle terminal, RSU (Road Side Unit), game control platform, or multimedia device.

[0084] Here, the first, second, and third identifiers may all be information for uniquely identifying a UE. For example, the first, second, and third identifiers may all be, but are not limited to, network layer identifiers or application layer identifiers. The network layer identifier may, but are not limited to, a SUCI (Subscription Concealed Identifier) ​​or a GUTI (Globally Unique Temporary UE Identity). In another example, the first, second, and third identifiers may all be, but are not limited to, the physical addresses of the UE. In yet another example, the first, second, and third identifiers may all be, but are not limited to, codes or indices agreed upon between the operator and the UE, or between the network device and the UE.

[0085] In one embodiment, the Ranging Service may be a Ranging / Sidelink (SL) positioning service. Here, the first request information includes a third identification information of a third UE for requesting the Ranging result of the Ranging / Sidelink positioning service, and a Ranging Service Code (RSC) for indicating the requested Ranging / Sidelink positioning service.

[0086] In one embodiment, the first request information may be ranging / side link position determination request information.

[0087] In one embodiment, the first UE transmits first request information to the second UE, which then transmits second request information to the first or second network node.

[0088] Here, the second request information includes a second identification, a first identification, a third identification, and a ranging service code. The second request information is used to request permission for the first UE to obtain the ranging results of the third UE. Here, the second request information being used to request permission for the first UE to obtain the ranging results of the third UE may also be used to request authorization for the first UE to obtain the ranging results of the third UE.

[0089] In one embodiment, the second request information may be used for the first UE to request permission to obtain the ranging results of the third UE in a ranging service indicated by the ranging service code. The ranging service may be a ranging / sidelink positioning service, or it may be any other ranging service, but is not limited thereto.

[0090] Here, the first network node, the second network node, and the third network node, as described below, may all be logical nodes, functions, or entities that are flexibly deployed in the communication network. For example, the first network node, the second network node, and the third network node are logical nodes or functions on the core network side.

[0091] In one embodiment, the first network node may be the PKMF of the second UE or the PCF of the second UE. For example, the first network node may be the PKMF of the assistant UE or the PCF of the assistant UE.

[0092] In one embodiment, the second network node may be a ranging positioning server. For example, the second network node is a ranging / sidelink positioning server.

[0093] In one embodiment, the third network node may be the PKMF or PCF of the first UE. For example, the third network node may be the PKMF or PCF of a third-party UE. In one embodiment, the second request information may be permission request information. Therefore, the second response information relating to the following may be permission response information.

[0094] In embodiments of this disclosure, the first UE may transmit first request information to the second UE, which includes first identification information of the first UE and second identification information of the second UE. The first request information is used to request the establishment of direct connection communication. The first request information includes third identification information of the third UE for requesting ranging results and ranging service code for instructing to request ranging services. This allows the second UE to discover whether to permit the first UE to obtain ranging results from the third UE during the direct connection communication establishment process, and the ranging results from the third UE are obtained only if the first UE is permitted to call the second UE to assist in obtaining ranging results from the third UE. This reduces the risk of an unauthorized and / or improperly behaving first UE obtaining ranging results from the third UE by allowing it to establish direct connection communication with the second UE.

[0095] For example, during the process of direct connection communication, the assistant UE can discover whether to allow a third-party UE to obtain ranging results for the measured UE or the target UE. This reduces the risk that a third-party UE that is not permitted to obtain ranging results for the measured UE or the target UE might obtain those results. In some embodiments, prior to step S31, the announcement information transmitted by the second UE is received.

[0096] In step S31, transmitting the first request information to the second UE includes decrypting the announcement information transmitted by the second UE based on key information in order to obtain the first information, and transmitting the first request information to the second UE.

[0097] The first piece of information is, Second identification information of the second UE; Role instruction information used to direct the role of the second UE; Range service code; and It includes at least one of the third identification information of the third UE.

[0098] One embodiment of the present disclosure provides an information processing method performed by a first UE, which includes decrypting announcement information transmitted by a second UE based on key information in order to obtain first information, and transmitting first request information to the second UE.

[0099] The first piece of information is, Second identification information of the second UE; Role instruction information used to direct the role of the second UE; Range service code; and It includes at least one of the third identification information of the third UE.

[0100] Thus, in the embodiments of this disclosure, under the premise that the second UE and the first UE discover each other, the first UE can request the establishment of a direct communication connection with the second UE, and the second UE can check whether or not to allow the first UE to obtain the ranging results of the third UE.

[0105] In one embodiment, the first response information includes the cause of the failure.

[0106] One embodiment of the present disclosure provides an information processing method that includes receiving first response information executed by a first UE and transmitted by a second UE, the first response information including the cause of failure.

[0107] Accordingly, in embodiments of the present disclosure, if the second UE determines that the first UE is not permitted to obtain the ranging results of the third UE, the second UE may notify the first UE that it is ceasing to establish a direct connection by ceasing to establish a direct connection and returning first response information carrying rejection instruction information.

[0181] As shown in Figure 8, one embodiment of the present disclosure provides an information processing method that is performed by a third network node and includes step S81.

[0182] Step S81: The first network node receives a second request information, which includes a second identification, a first identification, a third identification, and a ranging service code to instruct the request for ranging services, which is used to request permission for the first UE to obtain ranging results from the third UE, which is sent by the second UE after receiving the first request information, which is used to request the establishment of a direct communication connection between the first UE and the second UE.

[0197] In this way, if the third network node cannot authorize and authenticate the first UE to obtain the ranging result of the third UE based on the second request information, it can send the second request information to the second network node and decide to obtain authentication for the first UE to obtain the ranging result of the third UE. Thus, the decision of whether the first UE obtains authentication for obtaining the ranging result of the third UE can be made in various ways.

[0198] In one embodiment, the second network node is a ranging position determination server; and / or The first network node is the PKMF of the second UE or the PCF of the second UE; and / or The third network node is the PKMF of the first UE or the PCF of the first UE.

[0199] The above implementation modes can be found in the descriptions of the first UE and / or the second UE and / or the first network node and / or the third network node, but will not be repeated here.

[0200] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure may be performed alone or in conjunction with some of the methods in the embodiments of this disclosure or some of the methods in related technologies.

[0201] To further illustrate the embodiments of this disclosure, specific embodiments are provided below. Assuming that direct communication with a third-party UE uses the 3GPP® PC5 connection establishment process, and to prevent the third-party UE from requesting the ranging results of the measured UE without authorization, the assistant UE will be able to verify whether the third-party UE is authorized when receiving a direct communication request from the third-party UE, provided the request includes information about the measured UE. If the assistant UE itself does not have authorization information, it must request authorization services provided by the network. The network function that can authorize the third-party UE may also be a network function that provides the UE with ranging error information early in the authorization service and information provision process. Based on the authorization results provided by the network, the assistant UE will decide whether to proceed with securely establishing the PC5 connection.

[0202] As shown in Figure 9, embodiments of the present disclosure provide an information processing method performed by a communication device, the communication device including a measured UE or target UE (e.g., UE1 / UE2), an assistant UE, a third-party UE, the assistant UE's PKMF / PCF, the third-party UE's PKMF / PCF, and a ranging / SL positioning server. The information processing method includes the following steps: Step S901: The Assistant UE broadcasts protected announcement information, which includes information about the Assistant UE, role indication, ranging service code, and ranging exposure information.

[0203] Here, the ranging exposure information may be request information for requesting ranging / positioning results, which includes a list of information about the measured UEs on which the assistant UE can perform ranging. The information list may include the IDs of the measured UEs, for example, the Identifier (ID) of UE1 and / or UE2.

[0204] Step S902: The third-party UE monitors the broadcasted announcement information and discovers and selects an assistant UE based on the ranging outburst information.

[0205] Next, the third-party UE uses the discovery security parameters received from its PKMF / PCF / DDNMF to decrypt the protected announcement information. Since the discovery security parameters are associated with the information of the measured UE in the ranging information, only the discovery security parameters associated with the information of UE1 / UE2 can decrypt the announcement information.

[0206] Step S903: The third-party UE sends a Direct Communication Request (DCR) message to the Assistant UE in order to perform the process of establishing a PC5 connection with the Assistant UE.

[0207] Here, the direct communication request message may be the first request message in the above embodiment. The direct communication request includes at least information about the third-party UE, information about the assistant UE, a ranging service code, and information about the target UE from which the third-party UE requests ranging results (e.g., information about UE1 / UE2). Here, the information about the third-party UE, the information about the assistant UE, and the information about the target UE may each include at least a first identification information for the third-party UE, a second identification information for the assistant UE, and a third identification information for the target UE.

[0208] Of particular note is the risk that a malfunctioning third-party UE, which is not authorized to request ranging results from UE1 / UE2, can still respond to broadcast messages (such as announcement messages) from the assistant UE by sending a DCR to establish a PC5 connection with the assistant UE, and that the assistant UE declares its support for UE1 / UE2, but the assistant UE is unable to discover the malfunction.

[0209] Step S904: The assistant UE sends authorization request information to the assistant UE's PKMF / PCF, which includes at least the assistant UE's information, the third-party UE's information, the ranging service code, and the information of the target UE (UE1 / UE2) requested by the third-party UE.

[0210] Here, the permission request information may be the second request information in the above embodiment.

[0211] Step S905: The assistant UE's PKMF / PCF either sends authorization request information to the third party's UE's PKMF / PCF to authorize the third party, or interacts with the ranging / SL positioning server based on the third party's UE's PKMF / PCF to authorize the third party, or sends authorization request information directly to the ranging / SL positioning server to authorize the third party.

[0212] Here, allowing a third party means whether or not to allow the third party to request ranging results for the target UE (UE1 / UE2). The permission request information includes at least the third party's UE information, the target UE (UE1 / UE2) information requested by the third party's UE, and the ranging service code. The ranging / SL positioning server returns the permission result to the assistant UE's PKMF / PCF, either directly or via the third party's UE's PKMF / PCF.

[0213] Here, the permission result may be carried to permission response information, and this permission response information may be the second response information in the above embodiment.

[0214] Step S906: The PKMF / PCF of the Assistant Information UE returns the authorization result to the Assistant UE.

[0215] Step S907A: If authorization is successful, the assistant UE will directly perform the authorization and key establishment process with the third-party UE.

[0216] Here, a successful authorization means allowing a third-party UE to retrieve the ranging results of the target UE. After step S907A, proceed to step S908.

[0217] Step S907B: If permission fails, the Assistant UE directly sends communication denial information to the third-party UE.
