Reporting of user plan congestion
First Claim
1. A non-transitory machine readable storage medium having instructions embodied thereon, the instructions which when executed by one or more processors perform the following:
- identifying, at a radio access network (RAN) node, RAN user plane congestion (UPCON) information (RUCI) received from an operations and maintenance (OAM) system in the RAN; and
providing the RUCI from the RAN node to a policy and charging rules function (PCRF) in a core network (CN) via a mobility management entity (MME),wherein the RUCI is provided from the RAN node to the PCRF that is serving a packet data network (PDN) connection for a user equipment (UE) that is impacted by the UPCON,wherein the RUCI includes;
an access point name (APN) for which the UPCON is reported; and
a congestion level for a particular evolved universal terrestrial radio access network (EUTRAN) cell impacted by the UPCON,wherein the RUCI enables the PCRF to perform a policy decision using the RUCI to reduce UPCON at the RAN node.

Abstract
Technology for a radio access network (RAN) node that is operable to report user plane congestion (UPCON) is disclosed. The RAN node may include computer circuitry configured to receive, from a Core Network (CN), an information element (IE) including UPCON related Policy and Control Charging (PCC) information. The RAN node may identify a location of an UPCON event, at the RAN node, based on an UPCON event trigger included in the UPCON related PCC information. The RAN node may report Radio Access Network Congestion Information (RCI) about the UPCON event to one or more network elements in the CN.

11. A method for facilitating policy decisions based on user plane congestion (UPCON), the method comprising:
-
identifying, at a radio access network (RAN) node, RAN user plane congestion (UPCON) information (RUCI) received from an operations and maintenance (OAM) system in the RAN; and providing the RUCI from the RAN node to a policy and charging rules function (PCRF) in a core network (CN) via a mobility management entity (MME), wherein the RUCI is provided from the RAN node to the PCRF that is serving a packet data network (PDN) connection for a user equipment (UE) that is impacted by the UPCON, wherein the RUCI includes; an access point name (APN) for which the UPCON is reported; and a congestion level for a particular evolved universal terrestrial radio access network (EUTRAN) cell impacted by the UPCON, wherein the RUCI enables the PCRF to perform the policy decisions to reduce UPCON at the RAN node using the RUCI. - View Dependent Claims (12, 13, 14)
