Abstract

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 performedby AMFs and serving nodes, as well as UEs and network nodes configured to perform the exemplary methods.

Description

technical field [0001] The present application relates generally to the field of wireless communication networks, and more particularly to improvements that facilitate infrequent transmission and / or reception of small amounts of data by devices (eg, Internet of Things devices) operating in wireless communication networks. Background technique [0002] Multi-connectivity (also known as "Dual Connectivity" or "DC") can be envisioned as an important feature of the fifth generation (5G) RAN architecture standardized by 3GPP. figure 1 The figure shows a high-level view of the 5G network architecture, consisting of a Next Generation RAN (NG-RAN) 199 and a 5G Core (5GC) 198 . The NG-RAN 199 can include a set of gNodeBs (gNBs) connected to the 5GC via one or more NG interfaces, such as gNBs 100, 150 connected via interfaces 102, 152, respectively. Additionally, gNBs can be connected to each other via one or more Xn interfaces such as Xn interface 140 between gNBs 100 and 150 . Wit...
