1. A method to prevent RAN (Radio Access Network) overload, comprising: initiating, at a User Equipment (UE), a RRC (Radio Resource Control) connection establishment procedure to establish a RRC connection to a cell; and initiating, at the UE, a Random Access procedure due to a transmission of a RRCConnectionRequest message for the RRC connection establishment procedure wherein there is no barring information for delay tolerant access of the cell upon initiation of the Random Access procedure, wherein an establishment cause in the RRCConnectionRequest message is set to delay tolerant access; and stopping, at the UE, the Random Access procedure after the Random Access procedure has been initiated and is ongoing, and the UE receives updated barring information for delay tolerant access during the ongoing Random Access procedure specifying that the cell should be barred, wherein the barring information for delay tolerant access includes indications or parameters for EAB (Extended Access Barring).
