Access control in new radio
A method executed by a wireless device for network access of the wireless device to a network node is disclosed. The method includes initiating an access attempt to the network node; reading a first layer of access control information (ACI) from the network node to determine whether an access control indicator in the first layer for an access category is ON, wherein the access control indicator for the access category is associated with a characteristic/classification of the access attempt by the wireless device to the network node; in response to the access control indicator in the first layer for the access category being ON, reading a second layer of the ACI from the network node to determine whether the access attempt to the network node is allowed based on one or more specific parameters associated with the access category in the second layer of the ACI.
1. A method for a wireless device to trigger a Radio Access Network (RAN) Notification Area (RNA) update while the wireless device is in a Radio Resource Control (RRC) inactive (RRC_INACTIVE) state, the method comprising:
initiating an RRC resumption procedure for the RNA update;
acquiring an access control parameter configuration of an access category associated with the RNA update in system information block 1 (SIB 1 ) broadcast by a network node;
initiating a random access procedure for the RRC resumption procedure according to an indicator of the access control parameter configuration of the access category;
wherein, when the indicator is OFF, the indicator indicates to the wireless device that the wireless device does not need to apply the access control parameter configuration of the access category, and that the wireless device is allowed to initiate the random access procedure.
2. A wireless device configured to trigger a Radio Access Network (RAN) Notification Area (RNA) update while the wireless device is in a Radio Resource Control (RRC) inactive (RRC_INACTIVE) state, the wireless device comprising:
one or more processors;
a non-transitory machine-readable memory storing a program, the program executable by at least one of the one or more processors, the program comprising sets of instructions for:
initiating an RRC resumption procedure for the RNA update;
acquiring an access control parameter configuration of an access category associated with the RNA update in system information block 1 (SIB 1 ) broadcast by a network node;
initiating a random access procedure for the RRC resumption procedure according to an indicator of the access control parameter configuration of the access category;
wherein, when the indicator is OFF, the indicator indicates to the wireless device that the wireless device does not need to apply the access control parameter configuration of the access category, and that the wireless device is allowed to initiate the random access procedure.
