1. A method in a mobile device for managing access to resources of a cellular communication system, the cellular communication system including a plurality of base stations providing wireless access to the resources of the cellular communication system, the mobile device implementing an enhanced extended access class barring (EEAB) process to minimize overloading of the resources of the cellular communication system, the method comprising the steps of:

  • receiving system information from one of the plurality of base stations, the system information including an EAB mask and a shared rotation interval parameter;

    setting an implicit EAB mask for the mobile device using the received EAB mask, where the implicit EAB mask serves as a local working copy of the EAB mask;

    calculating a random offset using the received shared rotation interval parameter;

    starting an offset timer using the random offset;

    checking the implicit EAB mask to determine whether a class of the mobile device is barred;

    if the class of the mobile device is not barred, then enabling data access to the resources of the cellular communication system while the offset timer is active;

    if the class of the mobile device is barred, then baring data access to the resources of the cellular communication system while the offset timer is active; and

    checking whether the offset timer has expired;

    if the offset timer has expired, then updating the implicit EAB mask by shifting the implicit EAB mask, otherwise continuing to check for the offset timer to expire.
