A) Claims 1, 5, 8, 15, 17-18, 20, 33, and 35 are rejected under 35 U.S.C. 103 as being unpatentable over BYUN (WO 2021/182807 A1) in view of WANG (US 2023/0164648 A1).
As per claim 1, BYUN teaches a method performed by a wireless device for reporting failure information in a self-organizing network (SON) (¶0268-271, method performed by UE for reporting RLF information in SON), the method comprising:
receiving, from a source cell while being connected to the source cell, a handover command to attempt a handover from the source cell to a target cell, one or more bearers associated with the handover from the source cell to the target cell being configured with a dual active protocol stack ( DAPS) (¶0267 and ¶0281, receiving from source cell handover command to attempt handover from source cell to target cell data radio bearer (DRB) associated with the handover being configured with DAPS);
experiencing a failure while attempting the handover from the source cell to the target cell (¶0267 and ¶0163, failure occurs when attempting the handover from the source to target cell); performing a DAPS fallback to the source cell based at least in part on experiencing the failure while attempting the handover from the source cell to the target cell (¶0267, UE DAPS revert back (i.e. fallback) to the source cell when the DAPS handover to the target cell fails); experiencing a radio link failure, RLF, while being connected to the source cell in an RRC CONNECTED state after the DAPS fallback (¶0267 and ¶0271-272, RLF occurs while being connected to source cell in RRC connection mode after DAPS revert back).
However, ERICSSON does not explicitly teach storing first failure information associated with the failure while attempting the handover from the source cell to the target cell; storing second failure information associated with experiencing the, wherein storing the second failure information includes storing radio-measurement information indicating available radio measurements associated with a serving cell, a target cell, or a neighboring cell during a time duration between performing the DAPS fallback and experiencing the RLF while being connected to the source cell; and transmitting the first failure information or the second failure information towards the SON.
In the same field of endeavor, WANG teaches storing first failure information associated with the failure while attempting the handover from the source cell to the target cell (¶0376-78, storing first link failure information associated with failure while attempting the handover); storing second failure information associated with experiencing the RLF (¶0376-78, storing second link failure information associated with failure(i.e. RLF)), wherein storing the second failure information includes storing radio-measurement information indicating available radio measurements associated with a serving cell, a target cell, or a neighboring cell during a time duration between performing the DAPS fallback and experiencing the RLF while being connected to the source cell (¶0376-78 and ¶0169, storing measurement information indicating radio measurement associated with serving cell and time length during DAPS handover and experiencing failure while being connected to serving cell); and transmitting the first failure information or the second failure information towards the SON (¶0376-78, reporting or transmitting the he link failure related information to the network).
