Description

[Technical Field]

[0001] The present disclosure relates to the field of wireless communication technologies, and particularly, but not exclusively, to information processing methods, devices, communication devices, and storage media. [Background technology]

[0002] In the related technology, a third-party User Equipment (UE) obtains ranging / sidelink (SL) positioning results through an assistant UE. The assistant UE uses a direct connection discovery process to expose its ranging / SL positioning service to the third-party UE. The third-party UE does not need to have ranging / SL positioning capabilities, and can perform UE-to-UE discovery and assistant UE selection based on the assistant 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 invokes the ranging / SL location service of the assistant UE to obtain the ranging result between UE1 and UE2. The assistant UE performs ranging processes 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 ensure that a third-party UE is authorized to invoke a ranging service with an assistant UE. However, there is no existing method for an assistant UE to check whether a third-party UE is authorized to request ranging results for target UEs (e.g., UE1 and UE2). Therefore, the current security mechanism cannot prevent a suspicious third-party UE from requesting ranging results for target UEs (e.g., UE1 and UE2).

[0023] Reference may be made to Figure 1, which illustrates a schematic structural diagram of a wireless communication system provided by an embodiment of the present disclosure. As shown in Figure 1, the wireless communication system is a communication system based on cellular mobile communication technology, and may include a plurality of user equipments 110 and a plurality of base stations 120.

[0067] The user equipment 110 may be a device that provides a user with voice and / or data connectivity.

[0069] The base station 120 may be an evolved base station (eNB) used in a 4G system. Alternatively, the base station 120 may also be a base station (gNB) using a centralized-distributed architecture in a 5G system. When the base station 120 uses a centralized-distributed architecture, it generally includes a central unit (CU) and at least two distributed units (DUs). The centralized unit includes a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, and a Medium Access Control (MAC) layer.

[0072] Here, the user equipment can be regarded as a terminal device in the following embodiments.

[0073] In some embodiments, the wireless communication system may also include a network management device 130 .

[0074] The multiple base stations 120 are each connected to a network management device 130. The network management device 130 may be a core network device of a wireless communication system.

[0075] In order to facilitate the understanding of persons skilled in the art, the embodiments of the present disclosure will list several embodiments to clearly explain the technical solutions in the embodiments of the present disclosure. Obviously, those skilled in the art can understand that the several embodiments provided by the embodiments of the present disclosure can be implemented separately, can be implemented together with the methods of other embodiments in the embodiments of the present disclosure, or can be implemented separately or in combination with some embodiments in other related technologies. The embodiments of the present disclosure are not limited in this respect.

[0076] It should be noted that in embodiments of the present disclosure involving multiple execution entities, when one execution entity sends a transmission to another execution entity, this may refer to the execution entity sending the transmission directly to the other execution entity, or may refer to the execution entity sending the transmission to the other execution entity via any other device. Embodiments of the present disclosure are not limited in this respect.

[0077] In order to better understand the technical solutions described in any embodiment of the present disclosure, some descriptions of related technologies are first given.

[0078] As shown in Figure 2, the 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, the third-party UE and the assistant UE have completed mutual discovery and established the SL, so the third-party UE is a UE trusted by the assistant UE. When 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 the third-party UE is allowed to measure the distance between UE1 and UE2.

[0079] In some application scenarios, the assistant UE broadcasts advertisement information, including assistant UE information, role indication (i.e., "assistant UE"), 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 positioning. The third-party UE monitors the advertisement information and discovers the assistant UE based on the received ranging exposure information. If the target UE for which the third-party UE wishes to request a ranging result is included in the target UE information list in the ranging exposure information, the third-party UE selects the discovered assistant UE, and then the third-party UE establishes a secure PC5 connection with the assistant UE.

[0080] Assuming that the security establishment process for 5G ProSe direction communication defined in the related art can be reused for ranging in PC5 direct communication, current security mechanisms can only ensure that a third-party UE is authorized to invoke a ranging service with an assistant UE. However, according to the current specification, there is no existing method for an assistant UE to check whether a third-party UE is authorized to request ranging results for a target UE. Therefore, if a malfunctioning third-party UE that is not authorized to request ranging results for UE1 and UE2 responds to a broadcast message from the assistant UE informing 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 PC5 connection establishment, current security mechanisms cannot prevent the malfunctioning third-party UE from requesting ranging results for UE1 / UE2.

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

[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 a measured UE or a target UE. The assistant UE may be any UE that can perform ranging / SL positioning with a third UE (such as UE1 and UE2 in the above embodiment). For example, the assistant UE can find and measure UE1 and UE2 based on SL, respectively. The third-party UE may be any UE other than the assistant UE and the measured UE.

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

[0084] Here, the first identification information, the second identification information, and the third identification information may all be information for uniquely identifying the UE. For example, the first identification information, the second identification information, and the third identification information may all be, but are not limited to, either a network layer identification or an application layer identification. The network layer identification information may be, but is not limited to, a Subscription Concealed Identifier (SUCI) or a Globally Unique Temporary UE Identity (GUTI). In another example, the first identification information, the second identification information, and the third identification information may all be, but are not limited to, a physical address of the UE. In another example, the first identification information, the second identification information, and the third identification information may all be, but are not limited to, a code or index negotiated between an operator and the UE or between a network device and the UE.

[0085] In one embodiment, the ranging service may be a ranging / sidelink (SL) positioning service, where the first request information includes third identification information of a third UE for requesting a 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 / sidelink positioning request information.

[0087] In one embodiment, the first UE sends first request information to the second UE, causing the second UE to send second request information to the first network node or the second network node.

[0088] Wherein the second request information includes second identification information, first identification information, third identification information, and a ranging service code. The second request information is used by the first UE to request permission to obtain a ranging result of the third UE. Wherein, the second request information is used by the first UE to request permission to obtain the ranging result of the third UE may be referred to as the second request information is used by the first UE to request permission to obtain the ranging result of the third UE.

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

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

[0201] To further illustrate embodiments of the present disclosure, specific embodiments are provided below. Assuming that direct communication with a third-party UE uses the 3GPP PC5 connection establishment process, to prevent the third-party UE from requesting a ranging result for an unauthorized measured UE, if the request contains information about the measured UE, the assistant UE can verify whether the third-party UE has authorization when receiving a direct communication request from the third-party UE. If the assistant UE itself does not have authorization information, it must request an authorization service provided by the network. The network function that can authorize the third-party UE may be a network function that provides ranging information to the UE early in the authorization service and information provision process. Based on the authorization result provided by the network, the assistant UE decides whether to proceed with the secure establishment of a PC5 connection.

[0202] 9 , an embodiment of the present disclosure provides an information processing method performed by a communication device, where the communication device includes a subject UE or a target UE (e.g., UE1 / UE2), an assistant UE, a third party UE, a PKMF / PCF of the assistant UE, a PKMF / PCF of the third party UE, and a ranging / SL positioning server. The information processing method includes the following steps: Step S901: The assistant UE broadcasts protected advertisement information, where the advertisement information includes information of the assistant UE, a role indication, a ranging service code, and ranging exposure information.

[0203] Here, the ranging exposure information may be request information for requesting ranging / positioning results, including an information list of measured UEs that the assistant UE can perform ranging on, and the information list may include IDs of the measured UEs, such as the identifiers (IDs) of UE1 and / or UE2.

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

[0205] The third party UE then uses the discovery security parameters received from its PKMF / PCF / DDNMF to decrypt the protected advertisement information. Because the discovery security parameters are associated with the information of the monitored UE in the ranging information, only the discovery security parameters associated with the information of UE1 / UE2 can decrypt the advertisement information.

[0206] Step S903: The third party UE sends a direct communication request (DCR) message to the assistant UE to perform the establishment process of 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 (such as information about UE1 / UE2) for which the third party UE requests a ranging result. Here, the information about the third party UE, the information about the assistant UE, and the information about the target UE may include at least first identification information about the third party UE, second identification information about the assistant UE, and third identification information about the target UE, respectively.

[0208] It is worth noting that a misbehaving third party UE that is not authorized to request ranging results for UE1 / UE2 can still respond to a broadcast message (such as an advertisement message) from the assistant UE by sending a DCR to establish a PC5 connection with the assistant UE, and the assistant UE declares its support for UE1 / UE2, but there is a risk that the assistant UE will not be able to discover the misbehavior.

[0209] Step S904: The assistant UE sends permission request information to the PKMF / PCF of the assistant UE, where the permission request information includes at least the information of the assistant UE, the information of the third party UE, a 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 PKMF / PCF of the assistant UE sends authorization request information to the PKMF / PCF of the third party UE to authorize the third party, or interacts with the ranging / SL positioning server based on the PKMF / PCF of the third party UE to authorize the third party, or directly sends authorization request information to the ranging / SL positioning server to authorize the third party.

[0212] Here, authorizing a third party means whether to authorize the third party to request the ranging result of the target UE (UE1 / UE2). The authorization request information includes at least the information of the third party UE, the information of the target UE (UE1 / UE2) requested by the third party UE, and a ranging service code. The ranging / SL positioning server returns the authorization result to the PKMF / PCF of the assistant UE directly or via the PKMF / PCF of the third party UE.

[0213] Here, the authorization result may be carried in the authorization response information, which 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.
