| description | Aspects disclosed herein facilitate security handling of 5GS to EPC reselection are disclosed herein. An example method at a UE includes transmitting a first TAU request, the first TAU request encoded using a first security context associated with a first RAT, the first TAU request being integrity protected using a first uplink count based on the first security context, and the first TAU request including a first set of information including an identifier mapped to a second RAT associated with the first network entity. The example method also includes transmitting a second TAU request, the second TAU request including the first set of information, the second TAU request being integrity protected using a second uplink count. The example method also includes communicating based on a mapped security context based on the first security context and at least one of the first uplink count or the second uplink count. |
