Response to Arguments Applicant’s arguments with respect to claim(s) are rejected under 103, have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. As per claim 1, Applicant argued in the remark that the references do not teach or suggest claim limitations “requires that the tactical node gateway and tactical proxy are collocated within the M-TIP device, with the tactical proxy comprising authentication and session-management modules.

Claim Objections Claims 1 objected to because of the following informalities: As per clam 1 added the limitation "noncellular", however, the specification does not support the broad scope of this term. The silicification simply states that the tactical military network 200 may comprise a United States protected network, so it is unclear what network this tactical may be comprised of. For what it looks, the Applicant states that this is "a secret protocol", therefore there is no description provided that one of ordinary skill would know what the Applicant intend to be the claimed network. In this case, the Applicant amended to be "noncellular", however, this is a negative limitation, and the scope covers what is not rather than what it is. Any negative limitation or exclusionary proviso must have basis in the original disclosure, which is not the case. Since there are no alternative elements positively recited in the specification. Therefore, the amendment introduces new matter. Claim 1 added the limitation "noncellular", however, the specification does not support the broad scope of this term.

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) 1-2, and 6-20, rejected under 35 U.S.C. 103 as being unpatentable over Xu US 2015/0215725 and Holur et al US 6,990,086 and Meier et al US 2011/0103393. As per claim 1.

It facilitates roaming, protocol conversion (e.g., Diameter to SS7), and seamless service continuity); the tactical nodes use generic routing encapsulation uniformly for both control traffic and user plane traffic to the M-TIF device (0022, the Machine Type Communication Interworking Function (MTC-IWF),i.e. the tactical nodes, are a specialized network node that directly includes and manages Machine Type Communication (MTC/IoT) within 3GPP networks. It bridges external application servers (SCS) with mobile networks, managing device triggers, identifier mapping, and authorization for MTC devices); the M-TIF device hosts universal subscriber identity module (USIM) configuration data and performs proxy authentication, encryption, and session context management for the tactical nodes (fig.5, numeral 502 The USIM (Universal Subscriber Identity Module) resides on a card (UICC) that is inserted into the User Equipment (UE) or the mobile device, not within the network-side interworking function device (such as an N3IWF, TNGF, or TWIF)); the M-TIF device includes a classification and configured to apply predefined security classifications to communications routed to the gateway (fig. 5, numeral 502-507 an Interworking Function (IWF) device often performs classification and labeling (or tagging) as part of its role in bridging different network technologies, such as connecting 2G/3G to 4G LTE or integrating non-IP tactical nodes with 5G cores. The IWF facilitates this through protocol conversion, message encapsulation, and mapping service logic to ensure seamless communication); and the gNodeB and M-TIF are disposed in a mobile platform comprising at least one of a vehicle, aircraft, ship, or unmanned aerial system (fig. 5, numeral 502-507, the Interworking Function (IWF) is a critical component used in modern mobile tactical nodes—including those on aerial vehicles, ships, and ground vehicles—to bridge disparate, legacy, and advanced communication networks.

Xu fails to disclose the label module configure to the communication, the communication route to a tactile gateway of the set of the tactile nodes. However, Holur discloses the label module configure to the communication (col 10, lines 51-67 the foreign agent 70 updates the binding table 72 and generates an AAM 120 with the selected label in the vendor-specific extension 134. At step 348, the mobile unit 14, i.e. the label module configure to, receives the AAM 120 and extracts the data from the vendor-specific extension 134. At step 350, the SAM 224 updates the forwarding information base 248, informs the flow classifier 244 of the selected label, and sends the selected label to the appropriate application 222, at which point the method comes to an end. At this point, the application 222 may send and receive label-switched traffic to and from the network 22 through the serving node 24. Also, another application 222 may then request and be provided with a label assignment beginning with step 332.the mobile unit 14 can be any suitable mobile device to provide cellular communication and the mobile unit 14 the mobile unit 14 to the base station 38 where the frames are re-assembled to reconstitute the packets). Xu and Holur are both considered to be analogous to the claimed invention because they are in the same field of communication network by the network node. Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified Xu to incorporate the teachings of Holur and provide label-switched routing. Doing so would faster packet forwarding, superior traffic engineering, reduced congestion, and high-quality service delivery for latency-sensitive applications like voice and video. Therefore, improving the cellular communication. The combination fails to disclose the communication route to a tactile gateway of the set of the tactile nodes.

The gateway includes an inter-gateway communication interface that is communicatively couplable to a plurality of remote gateways and a processor. The processor is programmed to transmit, via the inter-gateway communication interface, a first gateway identifier for the gateway and a first gateway attribute for the gateway. The first gateway attribute includes a processing capacity indicator, processing usage indicator, a memory capacity indicator, and/or a memory usage indicator. The processor is also programmed to receive, via the inter-gateway communication interface, a second gateway identifier for a remote gateway and a second gateway attribute. The processor is further programmed to determine a desired primary gateway identifier based on the first gateway attribute and the second gateway attribute and transmit, via the inter-gateway communication interface, the desired primary gateway identifier. The desired primary gateway identifier is equal to the first gateway identifier or the second gateway identifier). As per claim 20. Xu and Holur and Meier discloses the M-TIF of Claim 16, Xu discloses further comprising one or more cryptographic guards logically interposed between the TWIF and the cellular network to support multiple independent levels of security for individual data connections (0059, the MTC-IWF may authenticate the MTC server sending the trigger message upon receiving the trigger message; when the MTC server is valid, the MTC server is authenticated, and MTC-IWF may accept the trigger message and perform step 303; or when the MTC server is invalid, the MTC server is not authenticated, and the trigger message may be discarded by the MTC-IWF and the MTC-IWF may send the MTC server a not-authenticated indication with a reason, and the flow ends). Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a).
