[0131] The network may attempt to optimize the network on the basis of the measurement result reported from UEs which assist the network operation);
an indication to indicate whether the measurement-based condition is fulfilled or not when receiving the handover command; and
a time difference between third time information regarding when receiving the handover command and fourth time information regarding when the measurement-based condition is fulfilled, in response to fulfilling the measurement-based condition when receiving the handover command.
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 invention of Zhang, in view of Deenoo, and further in view of Jung, which includes performing conditional handover, to include Jung’s teaching of performing conditional handover, for the benefit of supporting a mobility of user equipment in a wireless communication system (see [0007]).
Claim 22 is rejected under 35 U.S.C. 103 as being unpatentable over Zhang, in view of Deenoo, and further in view of Jung, and further in view of Kumar.
Regarding claim 22, Zhang, in view of Deenoo, and further in view of Jung, teaches the UE of claim 21.
Zhang, in view of Deenoo, and further in view of Jung, does not teach
wherein the at least one processor is configured to cause the UE to:
determine whether the location of the UE is located at the configured area within a duration of a timer to trigger (TTT).
In the same field of endeavor, Kumar teaches
wherein the at least one processor is configured to cause the UE to:
determine whether the location of the UE is located at the configured area within a duration of a timer to trigger (TTT)
([0030] A mobile unit moving at a velocity (v) should not be able to travel beyond D.sub.max (distance) before the handoff condition can be detected and the TTT and processing time required to make the handoff can elapse
(Determine whether mobile unit located at a distance within TTT)).
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 invention of Zhang, in view of Deenoo, and further in view of Jung, which includes performing conditional handover, to include Kumar’s teaching of performing conditional handover, for the benefit of avoiding ping-ponging, so that a mobile unit moving at a selected velocity does not travel beyond a third distance within the time-to-trigger TTT (see [0009]).
Conclusion
Citation of Pertinent Prior Art not Applied
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Yiu, et al (US PG Publication 2019/0029073), hereafter Yiu, teaches whether an AP measurement is performed at is based on information which the UE has previously received. This information could be, for example, whether or not there is an AP in the vicinity of the UE, the strength of nearby AP signal, the location of the UE itself.
