Claim(s) 27, 30, 31, 32, 35 are rejected under 35 U.S.C. 103 as being unpatentable over Shan (US 20190268835 A1 dated 20180518) in view of Talebi Fard et al. (US 20200100319 A1 dated 2020-03-26)
As to claim 27, Shan (US 20190268835 A1 dated 20180518) discloses (New) A method in a User Equipment, UE, configuration update procedure performed by a UE, the method comprising:
receiving, from a network node (AMF), a configuration update command (UE Configuration Update Command, Fig3) that comprises information that indicates to the UE that the UE is to perform a registration procedure ([0203]), and an indication which indicates whether or not the UE is to maintain an existing N1 non-access stratum, NAS, connection ([0205] – “…the AMF needs not release the NAS signaling connection for the UE”) of the UE (Paragraph [0196] – “ The AMF sends UE Configuration Update command […] to the UE.” [0203] – “If the Configuration Update Indication requires a Registration procedure, depending on the parameters included in the UE Configuration Update command steps 3a or 3b-4 or 3c-3d-4 are executed”); and
performing one or more actions ([0196] - The AMF sends UE Configuration Update command) in accordance with the configuration update command ([0196] - The AMF sends UE Configuration Update command), wherein performing the one or more actions comprise performing the registration procedure ([0203]) and determining whether to release or refrain from releasing the existing N1 NAS connection (Fig 3 – there are three paths, path1: 3a, path2: 3b and path3: 3c-3d. Here at 3b, AMF does not trigger AN release procedure and at 3c-3d, AMF triggers AN release procedure, thereby, the reference supports both limitations (releasing or refraining from releasing) in the claim. [0205] – “…the AMF needs not release the NAS signaling connection for the UE”) in accordance with the indication when performing the registration procedure (Paragraph [0196] – “The AMF sends UE Configuration Update command containing one or more UE parameters (5G-GUTI, TAI List, Allowed NSSAI, Mapping Of Allowed NSSAI, Configured NSSAI for the Serving PLMN, Mapping Of Configured NSSAI, NITZ, Mobility Restrictions, LADN Information, MICO, Configuration Update Indication, graceful re-register time)”; [0203] – “If the Configuration Update Indication requires a Registration procedure, depending on the parameters included in the UE Configuration Update command steps 3a or 3b-4 or 3c-3d-4 are executed”; [0205] – “3b. If a new Allowed NSSAI and/or a new Configured NSSAI provided by the AMF to the UE does not affect the existing connectivity to slices (i.e. any S-NSSAI(s) the UE is connected to), the AMF needs not release the NAS signaling connection for the UE”; [0207] - “4. UE initiates a Registration procedure after the UE enters CM-IDLE state and includes the 5G-GUTI in Access Stratum signalling depending on the indication received from the AMF.”).
Shan reference talks about AMF triggering the NAS connection release. Shan does not disclose that the UE determines whether to release or refrain from releasing the N1 NAS connection. However, a prior art, Talebi Fard et al. (US 20200100319 A1 dated 2020-03-26) discloses determining whether to release or refrain from releasing the existing N1 NAS connection ( Paragraph [0331] – “In an example embodiment, a wireless device (a UE) may request release of a connection (e.g., signaling/control plane connection, user plane connection, non-access stratum NAS connection, RRC connection, and/or the like).”)
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the wireless network of Shan et al to include the means to the UE releasing the NAS connection as taught by wireless network of Talebi Fard et al. in order to provide efficient and reliable method for release of network resources as mentioned in paragraph [0330].
As to claim 30, Shan (US 20190268835 A1 dated 20180518) discloses (New) The method of claim 27, wherein the network node (AMF) is an Access and Mobility Management Function, AMF (AMF).

and perform one or more actions ([0196] - The AMF sends UE Configuration Update command) in accordance with the configuration update command ([0196] - The AMF sends UE Configuration Update command), wherein perform the one or more actions comprise perform the registration procedure ([0203]) and determining whether to release or refrain from releasing the existing N1 NAS connection (Fig 3 – there are three paths, path1: 3a, path2: 3b and path3: 3c-3d. Here at 3b, AMF does not trigger AN release procedure and at 3c-3d, AMF triggers AN release procedure, thereby, the reference supports both limitations (releasing or refraining from releasing) in the claim. [0205] – “…the AMF needs not release the NAS signaling connection for the UE”) in accordance with the indication when performing the registration procedure (Paragraph [0196] – “The AMF sends UE Configuration Update command containing one or more UE parameters (5G-GUTI, TAI List, Allowed NSSAI, Mapping Of Allowed NSSAI, Configured NSSAI for the Serving PLMN, Mapping Of Configured NSSAI, NITZ, Mobility Restrictions, LADN Information, MICO, Configuration Update Indication, graceful re-register time)”; [0203] – “If the Configuration Update Indication requires a Registration procedure, depending on the parameters included in the UE Configuration Update command steps 3a or 3b-4 or 3c-3d-4 are executed”; [0205] – “3b. If a new Allowed NSSAI and/or a new Configured NSSAI provided by the AMF to the UE does not affect the existing connectivity to slices (i.e. any S-NSSAI(s) the UE is connected to), the AMF needs not release the NAS signaling connection for the UE”; [0207] - “4. UE initiates a Registration procedure after the UE enters CM-IDLE state and includes the 5G-GUTI in Access Stratum signalling depending on the indication received from the AMF.”).
