Should the changes and/or additions be unacceptable to applicant, an amendment may be filed as provided by 37 CFR 1.312. To ensure consideration of such an amendment, it MUST be submitted no later than the payment of the issue fee. Authorization for this examiner's amendment was given in by e-mail from Representative Rafael Pereira on 01/06/2026 The application has been amended regarding Claim 16 to Claim 20 as follows: CLAIM AMENDMENTS (16-20) 16. The non-transient computer-readable storage medium of claim 15, wherein the method generating a service based interface HTTP2 message for 5G. 17. The non-transient computer-readable storage medium of claim 16, wherein the method comprises assigning attributes for the initial attach request comprises a member, string value and value. 18. The non-transient computer-readable storage medium of claim 17, wherein the value identifies the originating RAT and the destination RAT. 19. The non-transient computer-readable storage medium of claim 15, further comprising: performing an audit of handovers for a subscriber based on the origination RAT and the destination RAT maintained in the subscriber profile associated with the wireless device. 20. The non-transient computer-readable storage medium of claim 15, further comprising: utilizing the origination RAT and destination RAT maintained in the subscriber profile for determining poor overage areas due to frequent handovers from the origination RAT to the destination RAT. 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 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. Claim(s) 1, 8, 15 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Park (US 2022/0240152 A1). Regarding Claim 1, 8, 15 Park discloses a system (See Fig.2), the system comprising: one or more hardware processors (See Fig.2; The devices in the system merely comprises processor) configured by machine-readable instructions (See [0039-0040]; devices comprises computer program instructions) to: receive an initial attach request (See [0085]; the UE 701 may transmit a control message requesting an initial attach to the network) from a wireless device (See Fig.2(201)); [0085]; UE) determine from the initial attach request (See [0085]; the UE 701 may transmit a control message requesting an initial attach to the network) an originating radio access technology (RAT) (See [0085-0086]; MME or AMF of the network determine first RAT) and a destination radio access technology (RAT) (See [0085-0086]; MME or AMF of the network determine second RAT) for the initial attach request (See [0085-0086]; in the message request) and transmit the originating RAT and destination RAT for the initial attach request (See [0085]; the UE 701 may transmit a control message requesting an initial attach to the network) to a subscriber profile (See [0086]; the first RAT network, for example, the MME (AMF in the case of 5G RAT network) 702 of the 4G RAT network, may request subscription information of the UE 701 from the HSS+UDM 704, and may receive the subscription information of the UE 701 from the HSS+UDM 704 in response to the subscription information request) associated with the wireless device (See Fig.2(201)); [0085]; UE).. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 2-7, 9-14, 16-18 are rejected under 35 U.S.C. 103 as being unpatentable by Park (US 2022/0240152 A1) in view of Ahmadi (US 2021/0092586 A1) Regarding Claim 2, 9, 16, Park teaches all the features with respect to claim 1, 8, 15 But Park fails to explicitly recite wherein the one or more hardware processors are further configured by machine-readable instructions to generate a service base interface (SBI) HTTP2 message for 5G. However in an analogous art, Ahmadi teaches about a network that uses service base interface (SBI) HTTP2 message for 5G in order to authenticate UE (See [0026-0027]). Park and Ahmadi are analogous art because they all pertain to cellular wireless technology where multiple RAT can be used to establish communication. Park teaches about a network determining a UE originating RAT and destination RAT through an initial attach request. Ahmadi teaches about a network that uses service base interface (SBI) HTTP2 message for 5G in order to authenticate UE through internetwork system. Park could use Ahmadi features in order to authenticate a UE through its subscription for use of other RAT network in UDM database. Therefore it would have been obvious to one of ordinary skill at the time of the filling of the application to combine Park and Ahmadi as to obtain an efficient cellular internetworking system. Regarding Claim 3, 10, 17 Park and Ahmadi teach all the features with respect to claim 2, 9, 16 and Park further teaches wherein the one or more hardware processors (See Fig.2; The devices in the system merely comprises processor) are further configured by machine-readable instructions (See [0039-0040]; devices comprises computer program instructions) to assign attributes for the initial attach request (See [0091-0092]; assigned attributes by receiving attach request from UE and from requesting subscription information from UDM/HSS) comprising a member (See [0091-0092]; support mobility between RATs), string value (See [0091-0092]; text data or integer is used to indicate mobility) value (See [0091-0092]; using handover for mobility between 4G and 5G) Regarding Claim 4, 11 Park and Ahmadi teach all the features with respect to claim 3, 10 and Ahmadi further teaches wherein the one or more hardware processors are further configured by machine-readable instructions to transmit the SBI HTTP2 message to a unified data management of a mobile network operator (See [0026-0027]; SBI HTTP2 message is transmitted to the UDM). Regarding Claim 5, 12 Park and Ahmadi teach all the features with respect to claim 4, 11 and Park further teaches wherein the one or more hardware processors are further configured by machine-readable instructions to update the subscriber profile for the wireless device (See [0087]; MME/AMF store updated requested subscription information from UDM/HSS) maintained in a unified data repository (See [0087]; UDM/HSS fetched subscription information from UDR) with corresponding fields for the attributes for the initial attach request (See [0091-0092]; assigned attributes by receiving attach request from UE and from requesting subscription information from UDM/HSS). Regarding Claim 6, 13 Park and Ahmadi teach all the features with respect to claim 3, 10 and Park further teaches wherein the member is handover type (See fig.5; [0076]; [0091]; an attach request comprising a handover type like RAT support for 4G/5G) . Regarding Claim 7, 14 Park and Ahmadi teach all the features with respect to claim 6, 13 and Bakker further teaches wherein the string value is handover (See fig.5; [0091]; [0113]; mobility support from 4G-5G is attributed through indication). Regarding Claim 18, Park and Ahmadi teach all the features with respect to claim 17 and Park further teaches wherein the value identifies the originating RAT and the destination RAT (See [0091-0092]; the values of RATs 4G/5G are stored in AMF/MME). Claim(s) 19 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Park (US 2022/0240152 A1) in view of Ahmadi (US 2021/0092586 A1) and further in view of Chin (US 2021/0329514 A1). Regarding Claim 19, Park and Ahmadi teach all the features with respect to claim 15 But fail to explicitly recite performing an audit of handovers for a subscriber based on the origination RAT and the destination RAT maintained in the subscriber profile associated with the wireless device. However in analogous art, Chin teaches a UE configured to track or monitor the quantity of handoffs that are performed between a first RAT and a second RAT during a time period (See [0028]). Park and Ahmadi are analogous art because they all pertain to cellular wireless technology where multiple RAT can be used to establish communication. Park teaches about a network determining a UE originating RAT and destination RAT through an initial attach request. Ahmadi teaches about a network that uses service base interface (SBI) HTTP2 message for 5G in order to authenticate UE through internetwork system. Chin teaches a UE configured to track or monitor the quantity of handoffs that are performed between a first RAT and a second RAT during a time period. Park and Ahmadi could use Chin features in order to evaluate area with signal degradation that result in multiple signal exchange between RATs. Therefore it would have been obvious to one of ordinary skill at the time of the filling of the application to combine Park, Ahmadi and Chin as to obtain an efficient cellular internetworking system. Regarding Claim 20, Park and Ahmadi teach all the features with respect to claim 15 But fail to explicitly recite utilizing the origination RAT and destination RAT maintained in the subscriber profile for determining poor overage areas due to frequent handovers from the origination RAT to the destination RAT. However in analogous art, Chin teaches about a UE with multiple RATs (LTE/NR) that is experiencing many RAT handovers due to degradation of signal throughput in creatin coverage area (See [0028]) Park and Ahmadi are analogous art because they all pertain to cellular wireless technology where multiple RAT can be used to establish communication. Park teaches about a network determining a UE originating RAT and destination RAT through an initial attach request. Ahmadi teaches about a network that uses service base interface (SBI) HTTP2 message for 5G in order to authenticate UE through internetwork system Chin teaches about a UE with multiple RATs (LTE/NR) that is experiencing many RAT handovers due to degradation of signal throughput in creatin coverage area. Park and Ahmadi could use Chin features in order to evaluate area with signal degradation using originating RAT and destination RAT that result in multiple signal exchange between them. Therefore it would have been obvious to one of ordinary skill at the time of the filling of the application to combine Park, Ahmadi and Chin as to obtain an efficient cellular internetworking system.
