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. ### Claim 2 (depends on 1) The apparatus according to claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to perform: determine if the apparatus is in an idle mode when transmission of user plane data is needed, and if the apparatus is in an idle mode when transmission of user plane data is needed, first initiate a service request procedure comprising sending a service request message, said service request message containing an indication that no user plane bearer needs to be established. ### Claim 3 (depends on 1) The apparatus according to claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to: prioritize regular non access stratum signaling over non access stratum signaling used for said transmission of user plane data over control plane. ### Claim 4 (depends on 1) The apparatus according to claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to: include in an attachment message an indication that said transmission of user plane data over control plane is needed. ### Claim 5 (depends on 1) The apparatus according to claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to: during an attachment procedure, provide an access point name indicating that no packet data network connection to a packet data network gateway needs to be established. ### Claim 6 A method, comprising: determining if transmission of user plane data is needed; determining if a user equipment has an active signaling bearer between the apparatus and a mobility management entity when transmission of user plane data is needed; and if the user equipment has an active signaling bearer between the user equipment and the mobility management entity when transmission of user plane data is needed, encapsulating 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. ### Claim 7 (depends on 6) The method according to claim 6, further comprising: determining if the user equipment is in an idle mode when transmission of user plane data is needed, and if the user equipment is in an idle mode when transmission of user plane data is needed, first initiating a service request procedure comprising sending a service request message, said service request message containing an indication that no user plane bearer needs to be established. ### Claim 8 (depends on 6) The method according to claim 6, further comprising: prioritizing regular non access stratum signaling over non access stratum signaling used for said transmission of user plane data over control plane. ### Claim 9 (depends on 6) The method according to claim 6, further comprising: including in an attachment message an indication that said transmission of user plane data over control plane is needed. ### Claim 10 (depends on 6) The method according to claim 6, further comprising: during an attachment procedure, providing an access point name indicating that no packet data network connection to a packet data network gateway needs to be established.
