Exemplary embodiments include methods performed by a cellular Internet of Things, CIoT, user equipment, UE, for transmission of data in a communication network comprising a radio access network, RAN, and a core network, CN. Embodiments include sending, to an Access and Mobility Management Function, AMF, a request to establish a small-data user-plane, SDUP, data session. Embodiments can also include receiving a response indicating that the requested SDUP data session is established. The response can include an identifier associated with a user-plane function, UPF, within the CN, that supports the established SDUP data session. The response can also include an SDUP security configuration for communication between the UE and the CN during the established SDUP data session. Embodiments can also include subsequently communicating user data, associated with the established SDUP data session, with the UPF via a serving node in the RAN. Other embodiments include complementary methods performed by AMFs and serving nodes, as well as UEs and network nodes configured to perform the exemplary methods.
