Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claims 1-7, and 16-27 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by "3rd Generation Partnership Project; Technical Specification Group Services and System Aspects; Study on the security of Access and Mobility Management Function (AMF) re-allocation; (Release 17)", 1 February 2021, pages 1-38, XP051999426; provided by Applicant; hereinafter referred to as 3GPP for simplicity.
Consider Claim 1, 3GPP shows an apparatus for performing a network function (see figure 6.6.2-1), the apparatus (read as AUSF), comprising: (a) At least one memory (see page 3; figure 6.6.2-1); (In step 3, the AUSF stores a received SNN and SUCI/SUPI temporarily in its local memory).
(b) At least one processor coupled with the at least one memory and configured to cause the apparatus to: receive a security request message from an initial access and mobility management function (AMF), an initial security anchor function (SEAF), or a combination thereof, wherein the security request message comprises information indicating a serving network name (SNN), whether routing information is required, a subscription permanent identifier (SUPI), or a combination thereof (see page 3; figure 6.6.2-1); (In step 2a-b, the initial AMF forwards the received initial UE message containing Registration Request to the SEAF by including the AMF Slice Capabilities. The SEAF further sends a Request message to the AUSF, which shall contain SUCI/SUPI, SNN and AMF Slice Capabilities. The AMF Slice Capabilities can indicate one or more slice(s) or service information).
(c) Determine routing information based on the security request message; and transmit a security response message to the initial AMF, the initial SEAF, or the combination thereof, wherein the security response message comprises the routing information (see page 31); (In step 8, the AUSF sends to the SEAF, the response message containing SUPI, authentication result as success, Slice Incompatibility Indication. The SEAF forwards the received SUPI, authentication result as success, the Slice Incompatibility Indication and AMF_AUTN to the initial AMF).
Consider Claim 16, 3GPP shows a method of performing a network function (see figure 6.6.2-1), the method comprising:
(a) Receiving a security request message from an initial access and mobility management function (AMF), an initial security anchor function (SEAF), or a combination thereof, wherein the security request message comprises information indicating a serving network name (SNN), whether routing information is required, a subscription permanent identifier (SUPI), or a combination thereof (see page 3; figure 6.6.2-1); (In step 2a-b, the initial AMF forwards the received initial UE message containing Registration Request to the SEAF by including the AMF Slice Capabilities. The SEAF further sends a Request message to the AUSF, which shall contain SUCI/SUPI, SNN and AMF Slice Capabilities. The AMF Slice Capabilities can indicate one or more slice(s) or service information).
(b) Determining routing information based on the security request message; and transmitting a security response message to the initial AMF, the initial SEAF, or the combination thereof, wherein the security response message comprises the routing information (see page 31); (In step 8, the AUSF sends to the SEAF, the response message containing SUPI, authentication result as success, Slice Incompatibility Indication. The SEAF forwards the received SUPI, authentication result as success, the Slice Incompatibility Indication and AMF_AUTN to the initial AMF).
Consider Claim 21, 3GPP shows a processor for wireless communication (see figure 6.6.2-1), comprising:
(a) At least one controller coupled with at least one memory and configured to cause the processor to: receive a security request message from an initial access and mobility management function (AMF), an initial security anchor function (SEAF), or a combination thereof, wherein the security request message comprises information indicating a serving network name (SNN), whether routing information is required, a subscription permanent identifier (SUPI), or a combination thereof (see page 3; figure 6.6.2-1); (In step 2a-b, the initial AMF forwards the received initial UE message containing Registration Request to the SEAF by including the AMF Slice Capabilities. The SEAF further sends a Request message to the AUSF, which shall contain SUCI/SUPI, SNN and AMF Slice Capabilities. The AMF Slice Capabilities can indicate one or more slice(s) or service information).
(b) Determine routing information based on the security request message; and transmit a security response message to the initial AMF, the initial SEAF, or the combination thereof, wherein the security response message comprises the routing information (see page 31); (In step 8, the AUSF sends to the SEAF, the response message containing SUPI, authentication result as success, Slice Incompatibility Indication. The SEAF forwards the received SUPI, authentication result as success, the Slice Incompatibility Indication and AMF_AUTN to the initial AMF).
Consider claims 2, 17, and 22, 3GPP shows that the at least one processor is configured to cause the apparatus to receive a key request message from a target AMF, a target SEAF, or a combination thereof, and the key request message comprises information indicating the SNN, the target AMF, or a combination thereof (see figure 6.6.2-1; and page 31); (see step 10a, key request).
Consider Claims 3, 18, and 23, 3GPP shows that the at least one processor is configured to cause the apparatus to derive a key based on the key request message, wherein deriving the key based on the key request message comprises deriving the key based on the target AMF (see figure 6.6.2-1; and page 31); (see step 10c, key response).
Consider Claims 4, 19, and 24, 3GPP shows that the at least one processor is configured to cause the apparatus to verify the SNN to verify whether the target AMF is authorized to use the SNN (see figure 6.6.2-1; and page 31); (In step 10b, the AUSF verifies the received AMF_AUTN based on the UE authentication information locally stored. If the Target AMF provided AMF_AUTN matches with the locally stored AMF_AUTN for a SUCI, then the
AUSF considers the AMF_AUTN verification (i.e., Reallocated AMF authentication) as successful and fetches the corresponding UE security context).
Consider Claims 5, 20, and 25, 3GPP shows that the at least one processor is configured to cause the apparatus to: transmit a key response message to the target AMF, the target SEAF, or the combination thereof, wherein the key response message comprises the key; and delete locally stored user equipment (UE) context information in response to transmitting the key response message (see figure 6.6.2-1; and pages 31-32); (In step 10b, the AUSF verifies the received AMF_AUTN based on the UE authentication information locally stored. If the Target AMF provided AMF_AUTN matches with the locally stored AMF_AUTN for a SUCI, then the AUSF considers the AMF_AUTN verification (i.e., Reallocated AMF authentication) as successful and fetches the corresponding UE security context. On receiving Security Context Request message, the AUSF based on the SUPI identifies Step 4. the locally stored security context (i.e., the one stored during primary authentication as in step 7b of Figure 6.6.2-1) and derives an authentication token for AMF (AMF_AUTN) using hash of AUSF key, SUPI and Target AMF Information Locally stores the AMF_AUTN and 5G-GUTI along with the SUPI and related information).
Consider Claims 6 and 26, 3GPP shows that the apparatus comprises an authentication server function (AUSF), a network function (NF), or a combination thereof (see figure 6.6.2-1).
Consider Claims 7 and 27 the routing information comprises an AUSF instance identifier (ID), a unified data management (UDM) instance ID, an AUSF group ID, a UDM group ID, AUSF identification information, UDM identification information, a routing indicator, network routing information, an AUSF address, a UDM address, or a combination thereof (see page 3; figure 6.6.2-1); (In step 2a-b, the initial AMF forwards the received initial UE message containing Registration Request to the SEAF by including the AMF Slice Capabilities. The SEAF further sends a Request message to the AUSF, which shall contain SUCI/SUPI, SNN and AMF Slice Capabilities. The AMF Slice Capabilities can indicate one or more slice(s) or service information).
