Claim Rejections - 35 USC § 103
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
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) 41- 42, 46- 47, 52, 55- 56 are rejected under 35 U.S.C. 103 as being unpatentable over R2-2110262 (see IDS filed on 7/5/2024) on page 2 cire No #2, hereafter CMCC in view of Roy et al. (US Pub. No. 2020/0314914 A1).
Regarding claim 41, CMCC teaches a control method, comprising following steps:
receiving a first time and a second time issued by a network device, wherein the first time is a service end time of the network device covering a current service area, and the second time is a service start time of a next network device covering the current service area; in response to meeting a first preset condition (RAN2 agrees that a cell broadcasts the time when a serving cell stops covering the current area (i.e. first time) and a reference location for a quasi-earth fixed cell in WI NR_NTN; see page 1 under section 2.1 discussion; further refer to same page 1 section 2.1about ..broadcast of cell stop time in an SIB is only applicable to the quasi-earth fixed cell; further see page 2 second paragraph under section 2.1…except the cell stop time, the start time of a next cell is beneficial for a user equipment (UE) to get satellite coverage; now see page 2 proposal 1 regarding For the quasi-earth fixed cell, satellite assistance information may comprise the stop time of the serving cell (i.e., a first preset condition), the start time of the next cell (i.e., a second time issued by a network device, the second time being a service start time of a next network device covering a current service area), etc. ; further refer to section 2.3.1 on page 3 about The UE predicts, according to the assistance information, how long the UE is out of coverage. Further see page 4 section 2.3.2 regarding When the UE is in an idle mode, the UE should camp on a suitable cell to obtain service…. When the UE is out of the coverage, the UE is not required to attempt to camp on a cell or connect to a network.).Here CMCC states that meeting preset condition, there is some delay in between the start time of next cell; but CMCC is silent about delaying, by a terminal, access to network for a preset time according to the second time, and the preset time is generated by the terminal; wherein
the step of in response to meeting the first preset condition, delaying, by the terminal, access to network for the preset time according to the second time comprises: determining the preset time; and
a manner for determining the preset time comprises:
determining or generating the preset time according to a first time range;
wherein the determining or generating the preset time according to the first time range comprises:
randomly selecting a duration as the preset time according to the duration T in a range of 0 to T, wherein T is a value greater than 0, or T is associated with a current load;
wherein the step of delaying, by the terminal, access to network for the preset time according to the second time comprises:
accessing, by the terminal, to network at a time of the second time plus the preset time.
However Roy teaches in context with [0030] and Fig. 5 (i.e. #501 as a network device and UE as a terminal) teaches in [0034] regarding …the HO Command message further includes an interval (similar to contention window). In step 522, all the UEs in the UE group use the interval in the HO Command message to first generate a number in the range [0, interval] and then perform a random backoff (i.e. random backoff can be a preset time). In step 523, each UE then transmits the PRACH preamble to the target base station gNB 502 in the new target cell at different times based on the random backoff number. As a result, different UEs perform the random-access at different times to avoid the RACH storm and thereby improving handover performance. In step 524, the target gNB 502 transmits a random-access response (RAR) to each UE (i.e. second time). Note that UEs and LEO-NTN can coordinate to use a two-step contention free random-access (CFRA) or contention based random-access (CBRA) for reducing the handover delay to cope with high-speed LEO satellites. Hence terminal accesses the network at a time of second time plus random backoff (between [0, interval] )time. Further this preset time is associated with load see [0030].. To solve this issue and mitigate enormous RACH collisions, LEO-NTN can provide contention free random-access (CFRA) resources to all (or the group) UEs in serving cell, such that all UEs can respond to the HO command message broadcast. However, CFRA-based random-access is limited by the number of available RA preambles. Thus, it might not be possible to resolve the massive RACH storm and resulting RACH failure in heavily loaded NTN; now refer to [0034] using an interval (similar to contention window)…. different UEs perform the random-access at different times to avoid the RACH storm and thereby improving handover performance.
It would have been obvious to one with ordinary skill, in the art before the effective filing date of the claimed invention was made to consider the teachings of Roy with the teachings of CMCC to make system more reliable. Having a mechanism wherein delaying, by a terminal, access to network for a preset time according to the second time, and the preset time is generated by the terminal; wherein
the step of in response to meeting the first preset condition, delaying, by the terminal, access to network for the preset time according to the second time comprises: determining the preset time; and
a manner for determining the preset time comprises:
determining or generating the preset time according to a first time range;
wherein the determining or generating the preset time according to the first time range comprises:
randomly selecting a duration as the preset time according to the duration T in a range of 0 to T, wherein T is a value greater than 0, or T is associated with a current load;
wherein the step of delaying, by the terminal, access to network for the preset time according to the second time comprises:

Regarding claim 42, CMCC in view of Roy teaches as per claim 41, wherein the meeting the first preset condition comprises at least one of: being released by the network before a first time, wherein the first time is issued by the network device; or accessing the network at the second time (CMCC see page 2 proposal 1 regarding For the quasi-earth fixed cell, satellite assistance information may comprise the stop time of the serving cell (i.e., a first preset condition), the start time of the next cell (i.e., a second time issued by a network device, the second time being a service start time of a next network device covering a current service area), etc).
Regarding claim 46, CMCC teaches a control method, comprising following steps:
receiving a first time and a second time issued by a network device, wherein the first time is a service end time of the network device covering a current service area, and the second time is a service start time of a next network device covering the current service area; in response to meeting a first preset condition (RAN2 agrees that a cell broadcasts the time when a serving cell stops covering the current area (i.e. first time) and a reference location for a quasi-earth fixed cell in WI NR_NTN; see page 1 under section 2.1 discussion; further refer to same page 1 section 2.1about ..broadcast of cell stop time in an SIB is only applicable to the quasi-earth fixed cell; further see page 2 second paragraph under section 2.1…except the cell stop time, the start time of a next cell is beneficial for a user equipment (UE) to get satellite coverage; now see page 2 proposal 1 regarding For the quasi-earth fixed cell, satellite assistance information may comprise the stop time of the serving cell (i.e., a first preset condition), the start time of the next cell (i.e., a second time issued by a network device, the second time being a service start time of a next network device covering a current service area), etc. ; further refer to section 2.3.1 on page 3 about The UE predicts, according to the assistance information, how long the UE is out of coverage. Further see page 4 section 2.3.2 regarding When the UE is in an idle mode, the UE should camp on a suitable cell to obtain service…. When the UE is out of the coverage, the UE is not required to attempt to camp on a cell or connect to a network.).
Here CMCC states that meeting preset condition, there is some delay in between the start time of next cell; but CMCC is silent about delaying, by a terminal, access to network for a preset time according to the second time, and the preset time is generated by the terminal; wherein
the step of in response to meeting the first preset condition, delaying, by the terminal, access to network for the preset time according to the second time comprises: determining the preset time; and
a manner for determining the preset time comprises:
determining or generating the preset time according to a first time range;
wherein the determining or generating the preset time according to the first time range comprises:

wherein the step of delaying, by the terminal, access to network for the preset time according to the second time comprises:
accessing, by the terminal, to network at a time of the second time plus the preset time.
