METHODS FOR PROVIDING REGULATION COMPLIANT PRIVACY AND RELATED APPARATUSES

RELATED APPLICATION

[0001] The présent application claims the benefit of and priority to U.S. Provisional

Patent Application No. 62/794,540 filed January 21, 2019, entitled METHODS FOR PROVIDING REGULATION COMPLIANT PRIVACY AND RELATED APPARATUSES the disclosure of which is hereby incorporated herein by reference in its entirety.

TECHNICAL FIELD

[0002] The present disclosure relates generally to wireless communications Systems and, more particulariy, to supervised régulation complaint privacy in a wireless network.

BACKGROUND

[0003] 5G is a next génération of mobile networks developed by a standard developing organization called the 3GPP. The earlier générations of mobile networks were called 4G/LTE, 3G/UMTS, and 2G/GSM.

[0004] A 5G network is maintained and its services are offered by the so-called 20 Mobile Network Operators (MNOs). MNOs are distinguishable from each other by two types of codes, namely the Mobile Country Code (MCC) and the Mobile Network Code (MNC).

[0005] To use a particular 5G network offered by a particular MNO, users are required to hâve a sort of contractuel relationship with that MNO. That relationship may be generally called the subscription. In cases when the user lacks a subscription to some 25 particular MNO (e.g., in a roaming scénario), the relationship is achieved by roaming agreements between the MNO where the user has a subscription, i.e., the useris Home Network (HN) and the MNO that the user is being served, i.e., the Visited Network (VN).

[0006] Each subscription in a MNO's 5G network is identified by a unique long-term identifier called the Subscription Permanent Identifier (SUPI). Users wirelessly access a 30 5G network over-the-air using wireless device known as User Equipment (UE), Before providing any service, a 5G network needs to identify a user, i.e., the user¹ s subscription, behind a UE. For this purpose of identification, UEs in earlier génération of mobile networks (4G, 3G, and 2G) would send users' unique long-term identifier over-the-air. This raised a potentiel privacy issue because users could be tracked or identified by any unauthorized 35 entity capable of intercepting message or acting as man-in-the-middîe over-the-air.

[0007] However, in a 5G network, the MNO has an ability to offer better privacy to its usera so that their unique long-term identifiera (i.e., SUPIs) are not visible over-the-air. That abiiity cornes from a mechanism in which UEs, instead of sending SUPIs, calculais and send concealed identifiera over-the-air, which is called the Subscription Concealed Identifier (SUCI). The MNO may make availab'e to UEs ail information that are necessary for the calculation of SUCI.

[0008] Without a loss of generality, the SUPI and the SUC! formats are outlined below.

[0009] The SUPI contains the following parts (separated by IJ); SUPI type |j SUPI value, where the SUPI value can be either of type IMSI or network spécifie identifier (also sometimes called as network access identifier or NAI). In either case, the SUPI value consiste of a home network identifier and a subscription identifier. The subscription identifier is what is concealed in the SUCI.

[0010] The SUCI contains the following parts (separated by ||): SUPI type j| Home Network identifier |} other parameters jj Concealed subscription identifier.

[0011] If the SUPI is of type IMSI, the Home Network Identifier consists of an Mobile Country Code (MCC) and Mobile Network Code (MNC) and the subscription identifier is called Mobile Subscription Identification Number (MSIN). If the SUPI is of type network spécifie identifier, the Home Network Identifier is generally represented by so-called realm and the subscription identifier is generally represented by so-called usemame, i.e., SUPI would look like usemame@realm. The exact définitions of SUPI can be found in 3GPPTS 23.003 V.15.6.0.

[0012] 3GPP 33.501 V.15.3.0 spécifiés that for SUPIs containing IMSI, the SUC! has following fields: the SUPI Type as defined in TS 23.003 V.15.6.0 identifies the type of the SUPI concealed in the SUCI; the Home Network Identifier is set to the MCC and MNC of the IMS! as specified in 23.003 V.15.6.0; the Routing Indicatoras specified in TS 23.003 V.15.6.0; the Protection Scheme Identifier as specified in Annex C of 3GPP TS 33.501 V.15.3.0; the Home Network Public Key Identifieras specified in 3GPP TS 33.501 V.15.3.0 and detailed in TS 23.003 V.15.6.0; and the Scheme Output as specified in this document and detailed in TS 23.003 V.15.6.0.

[0013] Further, 3GPP 33.501 V. 15.3.0 spécifiés that for SUPIs containing Network Spécifie Identifier, the SUCI in NAI format has following fields: the realm part of the SUCI is set to the realm part of the SUPI; and the usemame part of the SUCI is formatted as specifîed in TS 23.003 V, 15.6.0 using the SUPI Type, Routing Indicator, the Protection Scheme Identifier, the Home Network Public Key Identifier and the Scheme Output.

Potential Problemswith Existing Solutions

[0014] The following explanation of potential problems with existing solutions is a présent realization as part of the présent disclosure and is not to be construed as previously known by others.

[0015] A high level sequence diagram showing message flow comprising the SUCI is shown in Figure 1, which is a data flowdiagram illustrating a UE registration using SUCI. Referring to Figure 1, in operation 1. the UE connecte to a gNB over-the-air (the gNB being a 5G base station and part of the 5G Radio Access Network (RAN)) and sends a Registration Request message which comprises a SUCI caîculated by the UE. In operation 2, the gNB forwards the received Registration Request message to a cote network node. We dénoté that cote network node as an Access and Mobility Management Function (AMF) or Security Anchor Function (SEAF) interchangeably. The gNB and AMF/SEAF are collectively denoted as Serving Network (SN). The SEAF further locates the Authentication Server Function (AUSF). The SEAF then créâtes and sends to the AUSF. In operation 3, a 5G Authentication information Request (AIR) that among other information contains the received SUCI. The AUSF then contacts the Unified Data Management (UDM) or Subscription Identifier De-concealing Function (SIDF) function in operation 4.

[0015] The AUSF and UDFM/SIDF are collectively denoted as Home Network (HN). Note that the in case of roaming the SN and the HN belong to different MNOs while otherwise both the SN and HN belong to the same MNO.

[0017] Also note that registration involves more steps than these messages but this gives an overview of how the SUCI travels over the network.

[0018] Probiems with existing solutions include that when the SUPI (denoting a long-term identifier) is concealed between a UE and its HN, ail the network functions between them do not know the SUPI, including the SN. Therefore, it is challenging for the SN to fulfill its lawful interception obligations. This may not be acceptable because the SN must be able to fulfill its lawful interception obligations irrespective of whether the UEs in its network are roaming or not.

DETAILED DESCRIPTION

[0069] Inventive concepts will now be described more fully hereinafter with reference to the accompanying drawings, in which examples of embodiments of inventive concepts are shown. inventive concepts may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure wiil be thorough and complété, and will fully convey the scope of présent inventive concepts to those skilled in the art. It should also be noted that these embodiments are not mutually exclusive. Components from one embodiment may be tacitly assumed to be present/used in another embodiment.

[0070] The following description présents various embodiments of the disclosed subject matter. These embodiments are presented as teaching examples and are not to be construed as Jimiting the scope of the disclosed subject matter. For example, certain details of the described embodiments may be modified, omitted, orexpanded upon without départing from the scope of the described subject matter. The term terminal is used in a non-limiting manner and, as explained below, can refer to any type of radio communication terminal. The term terminal herein may be interchangeable replacer! with the term radio terminal, radio communication terminai, radio device, or user equipment (UE).

[0071] Further discussion of poiential problems provides that one potential solution is that the HN indiscriminately provides the SUPI (for ail SUCls served by the SN) to the 5 SN. Whîle this solution may provide an important aspect ïn fulfillïng Ll obligation, this solution is not sufficient on its own because the SN does not hâve any reliabie vérification that the HN provided the real or genuine SUPI. Therefore, the HN sending the SUPI to the SN may be necessary but is insufficient.

[0072] An additional solution may be that the SN vérifiés if the SUPI sent by the H N 10 actually belongs to the UE that the SN is serving. The SN could use variety of mechanisms for such vérification, e.g., calculating SUCI by encrypting the SUPI sent by the HN and comparing the calculated SUCI with the SUCI previously sent by the UE, obtaining an additional commitment value from the UE, obtaining another commitment-opener value from the HN, and verifying that the commitment-opener can verify the commitment, 15 calculating an expected response by using the SUPI sent by the HN, challenging the UE to send a response, and comparing the response sent by the UE with the calculated expected response, using SUPI sent by the H N in calculation of security keys so that if the UE uses different value, the communication breaks, etc.

[0073] White some sort of vérification by the SN may be yet another important 20 aspect in fulfitling Ll obligation, different sorts of above-mentioned vérification may hâve different properties and complexifies. Ultimately, 3GPP chose the last one of the abovementioned mechanisms, i.e., using SUPI in calculation of security key. This chosen mechanism may include the SUPI in the calculation of keys used for communication. Using this mechanism, the keys used by the SN and the UE will not match if the SN has received 25 the incorrect SUPI from the HN. if the UE and the SN hâve different keys they will not be able to communicate as they will disregard messages pretected with an incorrect key. The chesen mechanism is described in Clause6.1.3.1 for EAP-AKA’ and Clause 6.1.3.2 for 5GAKA in 3GPP TS 33.501 V15.3.0. The inclusion of SUPI is specified in Annex A.7 of 3GP TS 33.501 V15.3.0. Furthermore, there is discussion regarding whether or not to include 30 the whole SUPI in the calculation of security key. Some hâve suggested not to include the

SUPI type part of the SUPI into the calculation of the security key, and only use the SUPI value as input. An argument to exclude the SUPI type isfor simplicity. There are also other suggestions to include the SUPI type part of the SUPI into the calculation of the security key. One reason to include it may be to ensure the binding between the SUPI received 35 from the UE and from the HN.

[0074] While the above-mentioned mechanism may work, and whether or not the whole SUPI is used in calculation of security key, it still may not be sufficient for completely fulfilling the iawfui interception (U) obligation because there may not be any mechanism to link the SUCI received by the SN from the UE to the SUPI received by the SN from the HN. It may be a challenge forthe SN to hâve that linkage. And without such linkage, Ll obligation fuîfillment is questionable, which may be problematic.

[0075] In response to the above-described challenges, some embodiments herein are directed to enabling a network to fulfîll its lawfuî interception (Ll) obligation by ensuring that the subscription that was identified is the same as the one that gets the service. Such embodiments may provide a reliable Ll obligation fulfillment

[0076] As explained above, with the conceaiment of the SUPI between the UE and the HN, it may be challenging for the SN to fulfill its lawfui interception (Li) obligation because there may be no mechanism that enables the SN to link the SUCI received from the UE to the SUPI received from the HN. Accordingly, some embodiments herein may include a SUPI that is of type IMSI. Further, embodiments may be discussed in terms of MCC and MNC, however, such terms are mereîy exampie terms and the inventive concept is not so limited. As such, embodiments are applicable to fields/parameters/properties of SUCI and SUPI in general. Further, embodiments are not limited to a type IMSI SUPI. For example, embodiments are equalfy applicable to the SUPI of type network spécifie identifier. For example, in addition to checking MCC and MNC fields, the SN may check. other fields like the realm part of a SUPI of type Network Spécifie Identifier, SUPI Type etc. [0077] Reference is now made to Figure 2, which is a data flow diagram illustrating the procedure for SUPI binding according to some embodiments. In some embodiments, in operation 1 the UE sends the SUC! to the SN. In this example, the home network identifier consîsts of an MCC and a MNC, with values MCC_1 and MNC_1. According to operation 2, the SN forwards the received SUCI to the HN unmodified. Operation 3 provides that the HN couverts the SUCI and returns the SUPI to the SN. The SUPI contains the same MCC_1, MNC_1 as the SUCI. In operation 4, the SN uses the SUPI (part of, or complété, pending ongoing discussion) as input ta a calculation of the security key. Operation 5 provides that the UE uses the SUPI stored locally to dérivé the security key. If the local SUPI matches the SUPI in the SN, then the binding is successful, as illustrated in operation 6.

[0078] In some embodiments, the SUPI that is received from the HN may not match the SUCI that is provided by the UE. Reference is now made to Figure 3, which is a data flow diagram illustrating operations in which the SUPI does not match the SUCI according to some embodiments. Operation 1 illustrâtes that the UE sends the SUCI to the SN. in this example, the home network identifier consiste of an MCC and a MNC, with values MCC_1 and MNC_1, în operation 2, the SN forwards the received SUCl to the HN unmodified. In operation 3, the HN converts the SUCl and retums the SUPI to the SN. In this example, the H N retums the values MCC_2 and MNC_2. In operation 4, the SN uses the SUPI (part cf, or complété, pending ongoing discussion) as input to the calculations of the security key. In operation 5, the UE uses the SUPI stored locaily to dérivé the security key. Since the UE will use a SUPI with the values MCQ_1 and MNC_1, the UE and S N will not calcuiate the same key, as iîîustrated in operation 6.

[0079] Reference is now made to Figure 4, which is a data flow diagram iilustrating operations that include an authentication of parameters correspond in g to the SUPI and SUCl according to some embodiments. Operations include operation 1, in which the UE sends the SUCl to the SN. In this example, the home network identifier consists of an MCC and a MNC, having values MCC_1 and MNC_1, respectively. Operation 2 provides that the SN forwards the received SUCl to the HN in an unmodified State. In operation 3, the HN converts the SUC! and retums the SUPI to the SN. In this example, the HN retums the values MCC_x and MNC__x. In operation 4, the SN vérifiés that the SUPI parameters that were received from the HN matchesthe SUPI parameters received form the UE. Examples of parameters are MCC, MNC and/or SUPI type among others. If the parameters do not match, the SN shall not provide service to the UE and the following operations may not be performed. In some embodiments, the SN may send an erroror reject message to the UE. Some embodiments provide that the SN may inform HN of the error condition, in some embodiments, the SN may log the error condition, generate a report, and/or inform law enforcement agencies, among others.

[0080] Some embodiments provide that a similar conditOoin may resuit if the same values in SUPI are provided as different types. For example, conditions in which the same subscription information is contained in SUPI containing IMSI or SUPI containing Network Spécifie identifier (NSI). For example, #1 and #2 below could be arguable considered to be same. In such embodiments, the matching function corresponding to operation 4 will stîll verify that the values are the same regardless of SUPI type. For example, in example below #1, and #2 both hâve 123 and 45 for Home Network Identifier, and 6789100000 for subscription identifier.

1. SUPI Type (IMSI) || MCC (123) j| MNC (45) j| MSIN (6789100000)

2. SUPI Type (NSI) || usemame (6789100000) @ realm (MCC (123) . (MNC (45). corn)

[0081] In operation 5, the SN uses part or ail of the SUPI as input to the calculations of the security key. In operation 6, the UE uses the SUPI stored locaily to dérivé the security il key. If the local SUPI matches the SUPI in the SN, the binding may be identified as successful.

[0082] These and other reiated operations now be described in the contexi of the operational flowcharts of Figures 5-7 that may be performed by a mobile terminal.

[0083] Reference is now made to Figure 5, which illustrâtes operations that may be performed by a network device. Operations may include obtaining a concealed subscription identifier from a userequipment, UE (block 500). In some embodiments, the UE is associated with a home network, HN. The concealed subscription identifier is transmitted to the H N (block 502).

[0084] A permanent subscription identifier is obtained from the HN (block 504). Operations include determining whether the concealed subscription identifier from the UE corresponds to the permanent subscription identifier from the HN (block 506). I response to determining that the concealed subscription identifier from the UE corresponds to the permanent subscription identifier from the HN, operations include performing further operations to provide service to the UE (block 508). In response to determining that the concealed subscription identifier from the UE does not correspond to the permanent subscription identifier from the HN, operations include denying service to the UE (block 510).

[0085] In some embodiments, the concealed subscription identifier comprises a SUCI that is calculated by the UE based on information provided by the HN. Some embodiments provide that the permanent subscription identifier comprises a SUP1.

[0086] In some embodiments, the SUPI comprises an International Mobile Subscription Identifier, 1MSI, or a network spécifie identifier. Some embodiments provide that the concealed subscription identifier conceals the permanent subscription identifier, [οοβη In some embodiments, obtaining the concealed subscription identifier comprises obtaining a mobile country code, MCC, having a first MCC value and a mobile network code, MNC, having a first MNC value and obtaining the permanent subscription identifier comprises obtaining the MCC having a second MCC value and the MNC having the second MNC value. Some embodiments provide that determining that the concealed subscription identifier corresponds to the permanent subscription identifier comprises determining that the first MCC value equals the second MCC value and that the first MNC value equals the second MNC value.

[0088] In some embodiments, performing the subscription binding comprises performing the subscription binding using the second MCC value and the second MNC value, in some embodiments, subscription binding in the UE is based on the first MCC value and the first MNC value.

[0089] Some embodiments provide that deiermining whether the concealed subscription identifier corresponds to the permanent subscription identifier comprises generating a security key using at least a portion of the permanent subscription identifier for comparison to a security key that is generated by the UE using the permanent subscription identifier that is stored on the UE.

[0090] Reference is now made to Figure 6, which illustrâtes operations that may be performed for denying the service to the UE according to some embodiments. Operations may include rejecting service for the UE (block 600), logging an event corresponding to the concealed subscription identifier not corresponding to the permanent subscription identifier (block 602), notifying a law enforcement organization (block 604, and/or notifying the UE (block 606).

[0091] Reference is now made to Figure 7, which illustrâtes operations that may be performed by a mobile termina! according to some embodiments. Operations may include transmitting a concealed subscription identifier to a service network (block 700). In some embodiments, the concealed subscription identifier includes at least a first home network identifier, in some embodiments, the concealed subscription identifier includes a first MCC value and a first MNC value. Operations further include using a SUPI with at least the first home network identifier (block 702). A mobile terminal security key may be generated using a permanent subscription identifier that is stored on the mobile terminal. Operations may include performing a permanent subscription identifier binding. în some embodiments, the binding is performed with the service network based on the mobile terminal security key matching a service network generated security key that is based on a second MCC value and a second MNC value al the service network.

Examples of network nodes include, but are not iimited to, access points (APs) (e.g., radio access points), base stations (BSs) (e.g., radio base stations, Node Bs, evolved Node Bs (eNBs) and NR NodeBs (gNBs)). Base stations may be categorized based on the amount of coverage they provide (or, stated differently, their transmit power level) and may then also be referred to as femto base stations, pico base stations, micro base stations, or macro base stations. A base station may be a relay node or a relay donor node controlling a relay. A network node may also include one or more (or ail) parts of a distributed radio base station such as centralized digital units and/or remote radio units (RRUs), sometimes referred to as Remote Radio Heads (RRHs). Such remote radio units may or may not be integrated with an antenna as an antenna integrated radio.

[00112] Similarly, network node QQ160 may be composed of multiple physically separate components (e.g., a NodeB component and a RNC component, or a BTS component and a BSC component, etc.), which may each hâve their own respective components. In certain scénarios in which network node QQ160 comprises multiple separate components (e.g., BTS and BSC components), one or more of the separate components may be shared among several network nodes. For example, a single RNC may control multiple NodeB’s. In such a scénario, each unique NodeB and RNC pair, may in some instances be considered a single separate network node. In some embodiments, network node QQ160 may be configured to support multiple radio access technologies (RATs). In such embodiments, some components may be duplicated (e.g., separate device readabîe medium QQ180 for the different RATs) and some components may be reused (e.g., the same antenna QQ162 may be shared by the RATs). Network node QQ16Û may also include multiple sets of the various illustrated components for different wireless technologies integrated into network node QQ160, such as, for example, GSM, WCDMA, LTE, NR, WiFi, or Bluetooth wireless technologies.
