Abstract
A user equipment operating in a connected mode includes a first layer, a second layer, and a third layer. The first layer generates a request to send a non-initial non-access stratum (NAS) message over a first connection that operates according to a first radio access technology (RAT). The second layer determines whether access to the first connection is barred for the non-initial NAS message. The first layer selects a connection to deliver the non-initial NAS message between the first connection and a second connection that operates according to a second RAT in response to access to the first connection being barred. In some cases, the non-initial NAS message is a mobile originated short message service (SMS) message or an uplink NAS transport message. In some cases, the first layer is an NAS layer and the second layer is a radio resource control layer.
