  • Indicator-controlled utilization of outdated configuration defined in access information table for access network
    Patent number: 10368302
    Abstract: A radio device (10) receives an access information table (402) from the cellular network. The access information table (402) comprises parameters of a plurality of configurations for controlling access of the radio device (10) to the cellular network. Further, the radio device (10) receives an identifier (403) from the cellular network.
