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 may not be obtained though the invention is not identically disclosed or described as set forth in section 102 of this title, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negatived by the manner in which the invention was made.
Claims 1, 6, 11, and 16 are rejected under 35 U.S.C. 103 as being unpatentable over U.S. Patent Application Publication No. 2025/0220082 A1 Zhang et al. (“Zhang”) in view of U.S. Patent Application Publication No. 2025/0119460 A1 Zhang et al. (“Zhang2”) in further view of Printed Publication, “RFC 5939 – SDP Capability Negotiation” to Andreasen (“Andreasen”) in further view of U.S. Patent Application Publication No. 2025/0211628 A1 Zhang et al. (“Zhang3”).
As to claim 1, Zhang discloses:
a method of a user equipment (UE) in a wireless communication system, the method comprising:
transmitting, to an internet protocol multimedia subsystem application server (IMS AS), a registration request message including capability information for a data channel (DC) multiplexing (¶0032, ¶0033, ¶0056, ¶0057 - Zhang teaches transmission of capability requirement information or network node capability information between a UE 115 and a data channel server 120 may require use of network resources. One option for transmission of such information is during an IMS registration procedure, while a connection between the UE 115 and the data channel server 120 is being established.);
receiving, from the IMS AS, a registration response message in response to the registration request message (¶0057 – Zhang teaches The data channel server 120 may transmit an HTTP response including application information to the UE 115. The application information may include respective capability requirement information for one or more applications detailing hardware and/or software functionality required to use the respective applications or parts of the respective applications);
Zhang2 discloses what Zhang does not expressly disclose.
Zhang discloses:
transmitting, to an IMS AS, a session description protocol (SDP) offer on bootstrap DC, the SDP offer including a first bootstrap media description for a first bootstrap DC establishment (Fig. 4, ¶0052, ¶0053 – Zhang2 teaches UE may transmit, and the IMS-AS 408 may receive, an initial session description protocol (SDP) offer for a data channel that includes a data channel media description for one or more bootstrap data channels. A bootstrap data channel is a data channel that is established based at least in part on session description protocol information. The session description protocol information includes authentication information so that the bootstrap data channel can be used to distribute update data channel applications (and/or application updates) to a UE associated with the authentication information. In some aspects, the initial SDP offer for the data channel may be carried with an audio/video media description in an IMS session establishment communication. In some aspects, the initial SDP offer for the data channel may be carried in a separate invite request after an audio/video media channel is established successfully. And, the IMS-AS 408 may determine to establish a bootstrap data channel. The IMS-AS 408 may determine to establish the bootstrap data channel based at least in part on UE subscription information and/or a network operator policy.); and
receiving, from the IMS AS, a response message corresponding to the SDP offer for multiplexing the first bootstrap DC establishment between the UE and a DC media function (DCMF) (Fig. 4, ¶0054 – Zhang2 IMS-AS 408 may transmit an SDP offer response to the UE 402, indicating an acceptance of the initial SDP offer.),
Zhang and Zhang2 are analogous arts because they are from the same field of endeavor with respect to SDP and data channel establishment.
Before the effective filing date, it would have been obvious to a person of ordinary skill in the art to incorporate SDP offers and bootstrap channels as discussed in Zhangs with a method of a user equipment (UE) in a wireless communication system as discussed in Zhang by adding the functionality of Zhang2 to the system/method of Zhang in order to improve services that facilitate communications between network nodes associated with a telecommunication network like internet protocol multimedia subsystems (IMSs) which facilitates multimedia content transmission, reception, and delivery through a network (Zhang2, ¶0003).
Andreasen discloses what Zhang and Zhang2 does not expressly disclose.
Andreasen discloses:
identifying whether the IMS AS supports the DC multiplexing (p. 32, sec. 3.6 - Offer/Answer Model Extension, p. 32-35 - sec. 3.6.1 – Generating the Initial Offer, p. 35-41, sec. 3.6.2 – Generating the Answer – Andreasen teaches the answerer MUST first ensure that it supports any required capability negotiation extensions (see p. 35), and teaches that only attribute capabilities that are known or supported are included in the answer and unknown or unsupported attributed capabilities are not included (see p. 40-41));
Zhang, Zhang2 and Andreasen are analogous arts because they are from the same field of endeavor with respect to SDP and data channel establishment.
Before the effective filing date, it would have been obvious to a person of ordinary skill in the art to incorporate SDP capability negotiations as discussed in claim Andreasen with SDP offers and bootstrap channels as discussed in Zhang2 with a method of a user equipment (UE) in a wireless communication system as discussed in Zhang by adding the functionality of Zhang2 to the system/method of Zhang and Zhang2 in order to extend SDP with capability negotiation parameters and associated offer/answer procedures (Andreasen,p. 1, Abstract).
Zhang3 discloses what Zhang, Zhang2 and Andreasen do not expressly disclose. However, Zhang and Zhang2
Zhang3 discloses:
multiplexing of channels (¶0069 of Zhang3)
Zhang, Zhang2, Andreasen, Zhang3 are analogous arts because they are from the same field of endeavor with respect to SDP and data channel establishment.
Before the effective filing date, it would have been obvious to a person of ordinary skill in the art to incorporate multiplexing as discussed in Zhang3 with SDP capability negotiations as discussed in claim Andreasen with SDP offers and bootstrap channels as discussed in Zhang2 with a method of a user equipment (UE) in a wireless communication system as discussed in Zhang by adding the functionality of Zhang3 to the system/method of Zhang, Zhang2 and Andreasen in order to demonstrate that multiplex is usable within an IMS system (Zhang3, ¶0069).

Section 5.2.2 – Drage teaches the multiplexing category of the "a=dcsa:" attribute is SPECIAL.);
wherein the first attribute included in the SDP offer has an attribute value indicating that the UE supports the DC multiplexing (Sections 5.2, 6 – Drage teaches use of dcsa attributes within the SDP offer/answer procedures. Section 5.2.2 – Drage teaches the multiplexing category of the "a=dcsa:" attribute is SPECIAL.).
Zhang, Zhang2, Andreasen, Zhang3, Zhang4 and Drage are analogous arts because they are from the same field of endeavor with respect to SDP and data channel establishment.
Before the effective filing date, it would have been obvious to a person of ordinary skill in the art to incorporate SDP offer/answer parameters as discussed in Zhang4 and Drage with multiplexing as discussed in Zhang3 with SDP capability negotiations as discussed in claim Andreasen with SDP offers and bootstrap channels as discussed in Zhang2 with a method of a user equipment (UE) in a wireless communication system as discussed in Zhang by adding the functionality of Zhang4 and Drage to the system/method of Zhang, Zhang2, Andreasen and Zhang3 in order to demonstrate nable the communication parties to perform communication in addition to the voice call or the video call by using the data channel applications that can communicate with each othe (Zhang4, ¶0005) and specify how SDP offer/answer exchange is use to establish data channels (Drage, Abstrat).
