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 Radio Access Network (RAN) Notification Area (RNA) update by a wireless device, the method comprising:
receiving a first access control parameter configuration of an access category associated with the RNA update, while the wireless device is in a Radio Resource Control (RRC) inactive state (RRC_INACTIVE), the first access control parameter configuration of the access category associated with the RNA update being broadcast by a base station;
determining whether or not a random access procedure for the RNA update is allowed according to the first access control parameter configuration;
receiving a second access control parameter configuration associated with a particular type of random access;
determining whether or not the particular type of random access is allowed for the random access procedure for the RNA update according to the second access control parameter configuration; and
initiating the random access procedure for the RNA update according to an access control indicator of the first access control parameter configuration of the access category, wherein the random access procedure uses the particular type of random access when the particular type of random access is allowed.
2. The method of claim 1 , wherein the particular type of random access comprises a 2-step random access.
