Abstract
Various solutions to Non-Access Stratum (NAS) security and handling of multiple initial NAS messages with respect to a user equipment in mobile communications are described. A user equipment (UE) may transmit a first message regarding a first procedure to a mobile network element, and transmit a second message regarding a second procedure to the mobile network element. The UE may receive a reply from the mobile network element. In response to receiving the reply, the UE may perform one or more operations that result in the second procedure being continued and the first procedure being discontinued.
