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 of this title, 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.
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 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.
Claims 7 and 11 are rejected under 35 U.S.C. 103 as being unpatentable over Jeon, and further in view of Ohlsson et al. US Pub 2021/0195509 (hereinafter “Ohlsson”).
Regarding claim 7
Jeong previously discloses the network node according to claim 6,
Jeon does not specifically teach wherein the indication is encrypted by the UE using an encryption key of the first PLMN.
In an analogous art, Ohlsson discloses wherein the indication is encrypted by the UE using an encryption key of the first PLMN (“a NAS registration request including a Network Slice Selection Assistance information, NSSAI, encrypted using Public Land Mobile Network, PLMN, public key. The network node selects a network function based on information provided in the RRC connection request. The network nod forwards to the network function the NAS registration request. The network function decrypts the encrypted NSSAI using a PLMN private key.” [0019]).
Before the effective filling date of the claimed invention, it would have been obvious to one of ordinary skill in the art to modify Jeon’s method for supporting slice federation between public land mobile network (PLMN) operators in the wireless communication system, to include Ohlsson’s method for handling network slices in a wireless communication network, in order to efficiently provide network slices or functions (Ohlsson [Abstract]). Thus, a person of ordinary skill would have appreciated the ability to incorporate Ohlsson’s method for handling network slices in a wireless communication network into Jeon’s method for supporting slice federation between public land mobile network (PLMN) operators in the wireless communication system since the claimed invention is merely a combination of old elements, and in the combination each element merely would have performed the same function as it did separately, and one of ordinary skill in the art would have recognized that the results of the combination were predictable.
Regarding claim 11 (Currently Amended)
Jeong previously discloses the UE according to claim 10,
Jeon does not specifically teach to encrypt an indication indicating that the UE prefers PLMN selection that prioritizes network slice availability using an encryption key of a first PLMN.
In an analogous art, Ohlsson discloses (“a NAS registration request including a Network Slice Selection Assistance information, NSSAI, encrypted using Public Land Mobile Network, PLMN, public key. The network node selects a network function based on information provided in the RRC connection request. The network nod forwards to the network function the NAS registration request. The network function decrypts the encrypted NSSAI using a PLMN private key.” [0019]).
Before the effective filling date of the claimed invention, it would have been obvious to one of ordinary skill in the art to modify Jeon’s method for supporting slice federation between public land mobile network (PLMN) operators in the wireless communication system, to include Ohlsson’s method for handling network slices in a wireless communication network, in order to efficiently provide network slices or functions (Ohlsson [Abstract]). Thus, a person of ordinary skill would have appreciated the ability to incorporate Ohlsson’s method for handling network slices in a wireless communication network into Jeon’s method for supporting slice federation between public land mobile network (PLMN) operators in the wireless communication system since the claimed invention is merely a combination of old elements, and in the combination each element merely would have performed the same function as it did separately, and one of ordinary skill in the art would have recognized that the results of the combination were predictable.
Claim 16 is rejected under 35 U.S.C. 103 as being unpatentable over Jeon, and further in view of Park et al. US Pub 2020/0137675 (hereinafter “Park”).
Regarding claim 16
Jeong previously discloses the UE according to claim 10,
Jeon does not specifically teach wherein the at least one processor is configured to manage an Operator Controlled PLMN Selector with Access Technology data file per network slice of a first PLMN.
In an analogous art, Park discloses wherein the at least one processor is configured to manage an Operator Controlled PLMN Selector with Access Technology data file per network slice of a first PLMN (“The MS may select and attempt registration for a PLMN/access technology combination (when it is available and permitted) in all the operation bands according to the following order……. iii) A PLMN/access technology combination included in the “operator controlled PLMN selector with access technology” data file (depending on priority) of the SIM except for the PLMN/access technology combination previously selected” [0372]-[0375]).
Before the effective filling date of the claimed invention, it would have been obvious to one of ordinary skill in the art to modify Jeon’s method for supporting slice federation between public land mobile network (PLMN) operators in the wireless communication system, to include Park’s method for registering a terminal of an access and mobility management function (AMF), in order to efficiently facilitate registration procedure (Park [0006]). Thus, a person of ordinary skill would have appreciated the ability to incorporate Park’s method for registering a terminal of an access and mobility management function (AMF) into Jeon’s method for supporting slice federation between public land mobile network (PLMN) operators in the wireless communication system since the claimed invention is merely a combination of old elements, and in the combination each element merely would have performed the same function as it did separately, and one of ordinary skill in the art would have recognized that the results of the combination were predictable.
