Section: 6.5.3 RRC UE capability transfer procedure
Content: The network should activate AS security (i.e., perform a successful AS SMC procedure) before running the RRC UE capability transfer procedure. With the exception of unauthenticated emergency calls and the UEs using Control plane CIoT optimization,, if the network had acquired UE capabilities using RRC UE capability transfer procedure before AS security activation, then the network shall not store them locally for later use and shall not send them to other network entities. In that case, the network shall re-run the RRC UE capability transfer procedure after a successful AS SMC procedure. NOTE 1: For UEs without AS security (e.g., UEs using Control Plane CIoT optimization), RRC UE radio capability transfer procedure cannot be protected.
