1. An apparatus, comprising:
at least one processor; and
at least one memory including computer program code;
the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least perform:
determine if transmission of user plane data is needed;
determine if the apparatus has an active signaling bearer between the apparatus and a mobility management entity when transmission of user plane data is needed, and

if the apparatus has an active signaling bearer between the apparatus and the mobility management entity when transmission of user plane data is needed, encapsulate user plane data in a non access stratum signaling message, said non access stratum signaling message having, in a non access stratum signaling protocol, a message type indicating transmission of user plane data over control plane.
