Technology for reporting radio access network (RAN) user plane congestion (UPCON) is disclosed. In an example, a core network (CN) device can include computer circuitry configured to: receive an UPCON event report using an UPCON container that includes a congestion situation indicator to indicate a UPCON situation; and change an UPCON process based on the congestion situation indicator. The core network device can include a mobility management entity (MME), a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), a policy and charging enforcement function (PCEF), a policy and charging rules function (PCEF), a serving general packet radio service (GPRS) support node (SGSN), a gateway GPRS support node (GGSN), an access network discovery and selection function (ANDSF), an operation and maintenance (O&M) subsystem, an UPCON server, a proxy, or a standalone function entity. |
