Claim Rejections - 35 USC § 103
4. 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.
A) Claims 1-3, 5-8, 10, and 12-14 are rejected under 35 U.S.C. 103 as being unpatentable over Shaw (US 2018/0139670 A1) in view of FACCIN (US 2019/0124561 A1) and further in view of Gupta (US 2018/0063813 A1).
As per claim 1, Shaw teaches a virtualizing and interworking gateway (Shaw, Fig.1, ¶0034, virtual gateway 130), comprising: a virtual 5G core providing for 5G networks a plurality of virtualized 5G network functions (Shaw, Fig.1, ¶0022 and ¶0033-34, mobile packet core within 5G network 155 (i.e. 5G core) providing plurality of 5G virtual network functions); an interface to a core network (Shaw, Fig.1, ¶0020, air interface to a network); an interface to a 5G Radio Access Network (RAN) (Shaw, Fig.1, ¶0020 and ¶0022, LTE-Uu interface to 5G RAN).
However, Shaw does not explicitly teach an Interworking Function (IWF), the IWF including a shared IWF data store for 4G and 5G signaling, wherein the IWF interworks signaling between the 5G RAN and the core network by causing the shared IWF data store to emit data based on data received from the 5G RAN and interworked to parameters appropriate for the core network; wherein the virtualizing and interworking gateway provides interworking such that the 5G RAN works with the core network.
In the same field of endeavor, FACCIN teaches an Interworking Function (IWF), the IWF including a shared IWF data store for 4G and 5G signaling (FACCIN, ¶0076 and ¶0063, an Interworking Function including sharing data), wherein the IWF interworks signaling between the 5G RAN and the core network by causing the shared IWF data store to emit data based on data received from the 5G RAN and interworked to parameters appropriate for the core network (FACCIN, ¶0076 and ¶0106-107, interworking function signaling between 5G and core network by releasing/emit data based on the data received from the 5G network and interworked to parameters appropriate for the core network); wherein the virtualizing and interworking gateway provides interworking such that the 5G RAN works with the core network (FACCIN, ¶0029-30 and ¶0076, interworking and virtualization functions provides interworking between 5GS (e.g. 5G system) network and evolved packet core or EPC such that 5G radio access network (RAN) works with EPC connectivity).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of applicant’s claimed invention to have incorporated FACCIN into invention of Shaw in order to enable interworking between fifth generation system network slicing and evolved packet core connectivity to support and provide a desired level of speed or customization for efficient operation (FACCIN, ¶0005).
