1. An Enhanced NodeB (eNB) comprising:

  • memory; and

    hardware processing circuitry, configured to;

    detect disruption of a first S1 interface to a Core Network (CN);

    evaluate whether the eNB should assume a role of an autonomous eNB;

    responsive to assuming the role of the autonomous eNB, configuring the processing circuitry to;

    establish a second S1 interface with at least one other eNB; and

    provide a subset of functions provided by the CN to the at least one other eNB; and

    responsive to not assuming the role of the autonomous eNB, configuring the processing circuitry to;

    establish a second S1 interface with an eNB that has assumed the role of the autonomous eNB; and

    rely on the autonomous eNB to provide the subset of functions;

    wherein;

    the processing circuitry is further configured to;

    evaluate whether the eNB should assume the role of the autonomous eNB by being configured to compare a master priority of the eNB to master priorities of the at least one other eNB; and

    select as the autonomous eNB the eNB with a highest associated master priority;

    the master priorities of the at least one other eNB are computed by the eNB; and

    the master priorities of the at least one other eNB are computed after the S1 interface is disrupted.
