Abstract: Techniques for a selection or reselection a user-plane path in a mobile network are disclosed herein. A user-plane gateway (GW-U) can be configured to decode a packet received from a control plane gateway (GW-C) in a packet data network gateway (PGW) to determine a forwarding policy. Additionally, the GW-U can decode, from an evolved node B (eNB), an internet protocol (IP) packet having a header field. Furthermore, the GW-U can determine a user-plane path for the IP packet based on a comparison of the header field and the forwarding policy. Based on the determined user-plane path, the GW-U can forward the IP packet to a local application server (AS), encapsulate and forward the IP packet to the PGW, or discard the IP packet. Moreover, the GW-U can encode the IP packet for transmission based on the determined user-plane selection.

Abstract: Embodiments of a Next Generation Node B (gNB) are described herein. The gNB may be configured with logical nodes, including a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU may include a gNB-CU control plane (gNB-CU-CP) for control-plane functionality, and a gNB-CU user plane (gNB-CU-UP) for user-plane functionality. The gNB may initiate an E1 interface setup procedure, a bearer context setup procedure, and a UE context setup procedure to establish a UE context that includes a signaling radio bearer (SRB) and a data radio bearer (DRB) configuration. The UE context setup request message may be configured to include quality-of-service parameters for the DRB configuration.
