1. At least one non-transitory machine readable storage medium comprising a plurality of instructions executed to implement a method for core network signaling of an extended access barring (EAB) action to a node, comprising:
- receiving from a core network (CN) entity at a node an EAB action in an overload start message, wherein the core network entity includes a serving general packet radio services (GPRS) support node (SGSN) in a universal mobile telecommunications system (UMTS), the node includes a radio network controller (RNC), the EAB action is included in a priority class indicator IE or an EAB indicator IE, the overload start message includes a radio access network application part (RANAP) overload message, and the EAB action includes a barring category using two bit encoding;
receiving from the core network entity at the node a traffic load indication IE in the overload start message, wherein the traffic load indication IE defines an EAB percentage of wireless devices applying a barring category in the EAB action;
transmitting EAB configuration information from the node to a wireless device based on the received EAB action;
mapping the EAB percentage to an access class (AC) barring factor IE in an AC barring configuration in a system information block (SIB); and
transmitting the AC barring factor IE from the node to the wireless device via radio resource control (RRC) signaling.

Abstract
Technology for core network signaling of an extended access barring (EAB) action between a node (e.g., an eNodeB) and a core network (CN) entity (e.g., a mobility management entity (MME)) is disclosed. One method can include a node receiving from a core network entity an EAB action in an overload start message. The node can transmit EAB configuration information from the node to a wireless device based on the received EAB action.
