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 . Response to Remarks This Office action is considered fully responsive to the amendments filed 12/09/2025. Response to Arguments Applicant’s arguments, see Remarks, filed 12/09/2025, with respect to the rejection(s) of claim(s) 1-9, 15 and 30 under U.S.C. 102 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of EP 2978245 A1. With respect to the amendments to claims 3 and 15 (Remarks, page 7), see the prior art rejections below which address these limitations as they are specifically taught by Xu. All claims are rejected as indicated in the Claim Rejections section below. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 1-9, 15, 30 is/are rejected under 35 U.S.C. 103 as being unpatentable over U.S. Publication No. 2022/0217506 A1 to XU et al. (“Xu”) in view of EP 2978245 A1 to HAN.

(“Xu”) in view of n view of EP 2978245 A1 to HAN and in further view of U.S. Publication No. 2023/0345310 A1 to LI et al. (“Li”). As to claim 10, Xu and HAN does not expressly disclose the method of claim 9, wherein the MBS policy is determined by a policy control function (PCF) based on MBS service parameters provided by an application function (AF) and is provided to the CN function. Li discloses at para. 0274, notification control may be used for a GBR QoS Flow if the application traffic is able to adapt to the change in the QoS (e.g. if the AF 210 is capable to trigger rate adaptation). Upon receiving a notification from the NG-RAN that the GFBR can no longer be guaranteed, the AMF 203/SMF 204 may forward the notification to the PCF (e.g., UDM/PCF 206)… The evolved notification control parameter or the new Delivery Mode control parameter may be used by the core network (e.g., a network server or other entity) to indicate whether notifications are requested from the NG-RAN when QoS requirement can no longer be met using the currently configured delivery mode, or to request delivery mode switch from MBMS user service (Multicast/Broadcast) to Unicast service, or to request delivery mode switch from unicast service to MBMS user service (Multicast/Broadcast). Prior to the effective filing date of invention, it would have been obvious to a person of ordinary skill in the art to incorporate the notification as taught by Li into the invention of Xu and HAN. The suggestion/motivation would have been to provide switching between at least two unicast messaging, multicast messaging, and broadcast messaging to a user device over a 5G network (Li, para. 0006).

In addition, if there is only one remaining UE receiving the multicast traffic, the network may switch the UE 201 to using unicast session for better mobility handling of the traffic in case the UE 201 moves, i.e. core network detects UE movement (i.e. assistance information) from NWDAF. [para. 0134, core network function…network functions…NWDAF, i.e. NWDAF is a core network function, hence core network is subscribed to it]. Prior to the effective filing date of invention, it would have been obvious to a person of ordinary skill in the art to incorporate the NWDAF as taught by Li into the invention of Xu and HAN. The suggestion/motivation would have been to provide switching between at least two unicast messaging, multicast messaging, and broadcast messaging to a user device over a 5G network (Li, para. 0006). Including the NWDAF as taught by Li into the invention of Xu and HAN was within the ordinary ability of one of ordinary skill in the art based on the teachings of Li. As to claim 13, Xu and HAN does not expressly disclose method of claim 11, wherein the analytics information comprises one or more of the following types: service experience; network performance; user data congestion; quality of service (QoS) sustainability; or network function (NF) load. Li discloses NWDAF finds or predicts that the data transfer performance within core network cannot meet requirement, or that UE 201 moves out of MBS session service area. In addition, if there is only one remaining UE receiving the multicast traffic, the network may switch the UE 201 to using unicast session for better mobility handling of the traffic in case the UE 201 moves, i.e. movement of UE outside area is a service experience (less UEs to service), network performance (need to swtich to unicast), and NF load (less UEs to service) (para. 0218). Prior to the effective filing date of invention, it would have been obvious to a person of ordinary skill in the art to incorporate the NWDAF as taught by Li into the invention of Xu and HAN. The suggestion/motivation would have been to provide switching between at least two unicast messaging, multicast messaging, and broadcast messaging to a user device over a 5G network (Li, para. 0006). Including the NWDAF as taught by Li into the invention of Xu and HAN was within the ordinary ability of one of ordinary skill in the art based on the teachings of Li. As to claim 14, Xu and HAN does not expressly disclose the method of claim 11, wherein the determining the MBS assistance information according to the analytics information, comprises: in case that the CN function is an application function (AF), updating, by the AF, MBS service parameters according to the analytics information, and sending the updated MBS service parameters to a policy control function (PCF); or in case that the CN function is a policy control function (PCF), updating, by the PCF, MBS policies according to the analytics information and/or the updated MBS service parameters, and sending the updated MBS policies to a session management function (SMF); or in case that the CN equipment is the SMF, determining, by the SMF, the MBS assistance information based on one or more of the following parameters: the analytics information; the updated MBS policies; UE subscription data related to MBS services, which is obtained by the SMF from the unified data management (UDM); or information sent by the UE to the SMF through non-access stratum (NAS) signaling. Li discloses FIG. 3 illustrates an exemplary NAS transport for SM, SMS, UE Policy, or LCS. It is worth noting that the mobility management and session management functions are separated. A single N1 NAS connection is used for both Registration Management and Connection Management (RM/CM) and for SM-related messages and procedures for a UE. The single N1 termination point is located in the AMF. The AMF forwards SM related NAS information to the SMF. AMF handles the Registration Management and Connection Management of NAS signaling exchanged with the UE, while SMF handles the Session management of NAS signaling exchanged with the UE (para. 0087); para. 0137, the UE sends a NAS message to the AMF requesting to switch to the multicast transmission mode (e.g., a control plane method as shown in FIG. 7A-FIG. 7B), i.e. or in case that the CN equipment is the SMF, determining, by the SMF, the MBS assistance information based on one or more of the following parameters… information sent by the UE to the SMF through non-access stratum (NAS) signaling. Prior to the effective filing date of invention, it would have been obvious to a person of ordinary skill in the art to incorporate the SMF as taught by Li into the invention of Xu and HAN. The suggestion/motivation would have been to provide switching between at least two unicast messaging, multicast messaging, and broadcast messaging to a user device over a 5G network (Li, para. 0006). Including the SMF as taught by Li into the invention of Xu and HAN was within the ordinary ability of one of ordinary skill in the art based on the teachings of Li. Examiner notes that the instant claim recites contingent limitations using the terms “in case” that do not need to be given patentable weight. However, in the interest of Compact Prosecution, Examiner cited to prior art to teach the contingent limitation(s). See MPEP 2111.04 for details. As to claim 31, Xu and HAN does not expressly disclose the core network (CN) function or an operation, administration and maintenance (OAM) platform, including a processor, and a memory storing a processor-executable program that, when executed by the processor, causes the processor to perform steps of the method for determining a delivery mode of claim 8. Li discloses the Core Network…comprise a computer or server and may be controlled primarily by computer readable instructions, which may be in the form of software, wherever, or by whatever means such software is stored or accessed. Such computer readable instructions may be executed within a processor 91, to cause computing system 90 to do work (para. 0076). Prior to the effective filing date of invention, it would have been obvious to a person of ordinary skill in the art to incorporate the Core Network as taught by Li into the invention of Xu and HAN. The suggestion/motivation would have been to provide switching between at least two unicast messaging, multicast messaging, and broadcast messaging to a user device over a 5G network (Li, para. 0006). Including the Core Network as taught by Li into the invention of Xu and HAN was within the ordinary ability of one of ordinary skill in the art based on the teachings of Li. 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).
