Office Action

§103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 12/19/25 has been entered. Response to Arguments Applicant’s arguments with respect to claim(s) 1, 16-19 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. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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, 16-19 are rejected under 35 U.S.C. 103 as being unpatentable over as applied to Ratilainen et al (Pub No: 2019/0222967), and further in view of Hong (Pub No: 2023/0082017). As to claim 1, Ratilainen teaches a communication control method used in a mobile communication system for providing a multicast broadcast service (MBS) from a network node to a user equipment (Ratilainen, [0017] Fig 1, method for a system of a network node and a user equipment for multicast/broadcast transmission service), the communication control method comprising: receiving, by the user equipment from the network node information related to a multicast session (Ratilainen, [0088], the wireless device UE receives from the network node control information for a multicast or broadcast transmission session); and when there is temporarily no data for the multicast session, in response to receiving the information from the network node, stopping, by the user equipment, monitoring using a G-RNTI (Group Radio Network Temporary Identifier) for the multicast session (Ratilainen, [0088], when multicast data transmission is completed (temporarily no data), the device can stop monitoring with a G-RNTI, in response to the explicit control signaling) . Ratilainen does not explicitly teach a Radio Resource Control (RRC) message including information related to a multicast session. However, Hong teaches a Radio Resource Control (RRC) message including information related to a multicast session. (Hong, [0167][0184], a RRC message is received by a UE from a base station with MBS (multicast) session information). Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing data of the claimed invention to provide “an RRC message with multicast session information” as taught by Hong in the system of Ratilainen, so that it would increase efficiency and service continuity during a MBS session in NR (Hong, [0004]). As to claim 16, Ratilainen teaches a user equipment configured to receive a multicast broadcast service (MBS) from a network node (Ratilainen, [0017] [0128] Fig 1, a user equipment for multicast/broadcast transmission service with a network node), the user equipment comprising: a receiver configured to receive from the network node, information related to a multicast session (Ratilainen, [0088], the wireless device UE receives from the network node control information for a multicast or broadcast transmission session), and a controller configured to, when there is temporarily no data for the multicast session, in response to receiving the information from the network node, stop monitoring using a G-RNTI (Group Radio Network Temporary Identifier) for the multicast session (Ratilainen, [0088], when multicast data transmission is completed (temporarily no data), the device can stop monitoring with a G-RNTI, in response to the explicit control signaling) . Ratilainen does not explicitly teach a Radio Resource Control (RRC) message including information related to a multicast session. However, Hong teaches a Radio Resource Control (RRC) message including information related to a multicast session. (Hong, [0167][0184], a RRC message is received by a UE from a base station with MBS (multicast) session information). Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing data of the claimed invention to provide “an RRC message with multicast session information” as taught by Hong in the system of Ratilainen, so that it would increase efficiency and service continuity during a MBS session in NR (Hong, [0004]). As to claim 17, Ratilainen teaches a chipset for a user equipment configured to receive a multicast broadcast service (MBS) from a network node (Ratilainen, [0017] [0128] Fig 1, a user equipment for multicast/broadcast transmission service with a network node),, the chipset configured to execute processing of: receiving from the network node, information related to a multicast session (Ratilainen, [0088], the wireless device UE receives from the network node control information for a multicast or broadcast transmission session); and when there is temporarily no data for the multicast session, in response to receiving the information from the network node, stopping monitoring using a G-RNTI (Group Radio Network Temporary Identifier) for the multicast session (Ratilainen, [0088], when multicast data transmission is completed (temporarily no data), the device can stop monitoring with a G-RNTI, in response to the explicit control signaling) . Ratilainen does not explicitly teach a Radio Resource Control (RRC) message including information related to a multicast session. However, Hong teaches a Radio Resource Control (RRC) message including information related to a multicast session. (Hong, [0167][0184], a RRC message is received by a UE from a base station with MBS (multicast) session information). Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing data of the claimed invention to provide “an RRC message with multicast session information” as taught by Hong in the system of Ratilainen, so that it would increase efficiency and service continuity during a MBS session in NR (Hong, [0004]). As to claim 18, Ratilainen teaches a non-transitory computer-readable medium comprising, stored thereupon, computer program instructions for execution by a user equipment (Ratilainen, [0017] Fig 1, a user equipment with memory for multicast/broadcast transmission service), the program instructions being configured to cause the user equipment to execute processing of: receiving from a network node, information related to a multicast session (Ratilainen, [0088], the wireless device UE receives from the network node control information for a multicast or broadcast transmission session); and when there is temporarily no data for the multicast session, in response to receiving the information from the network node, stopping monitoring using a G-RNTI (Group Radio Network Temporary Identifier) for the multicast session (Ratilainen, [0088], when multicast data transmission is completed (temporarily no data), the device can stop monitoring with a G-RNTI, in response to the explicit control signaling) . Ratilainen does not explicitly teach a Radio Resource Control (RRC) message including information related to a multicast session. However, Hong teaches a Radio Resource Control (RRC) message including information related to a multicast session. (Hong, [0167][0184], a RRC message is received by a UE from a base station with MBS (multicast) session information). Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing data of the claimed invention to provide “an RRC message with multicast session information” as taught by Hong in the system of Ratilainen, so that it would increase efficiency and service continuity during a MBS session in NR (Hong, [0004]). As to claim 19, Ratilainen teaches a system comprising: a network node, and a user equipment configured to receive a multicast broadcast service (MBS) from the network node (Ratilainen, [0017] Fig 1, a system of a network node and a user equipment for multicast/broadcast transmission service), wherein the user equipment is configured to receive from the network node, information related to a multicast session (Ratilainen, [0088], the wireless device UE receives from the network node control information for a multicast or broadcast transmission session), and when there is temporarily no data for the multicast session, in response to receiving the information from the network node, stop monitoring using a G-RNTI (Group Radio Network Temporary Identifier) for the multicast session (Ratilainen, [0088], when multicast data transmission is completed (temporarily no data), the device can stop monitoring with a G-RNTI, in response to the explicit control signaling) . Ratilainen does not explicitly teach a Radio Resource Control (RRC) message including information related to a multicast session. However, Hong teaches a Radio Resource Control (RRC) message including information related to a multicast session. (Hong, [0167][0184], a RRC message is received by a UE from a base station with MBS (multicast) session information). Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing data of the claimed invention to provide “an RRC message with multicast session information” as taught by Hong in the system of Ratilainen, so that it would increase efficiency and service continuity during a MBS session in NR (Hong, [0004]).
