1. A method comprising:

  • determining, by a mobile initiator device comprising a processor, a physical cell identifier of a camping cell site upon which the mobile initiator device is camping;

    determining, by the mobile initiator device, based upon the physical cell identifier, whether at least one passive near-field communication device is available in the camping cell site;

    when the at least one passive near-field communication device is available in the camping cell site, activating, by the mobile initiator device, via a near-field communication hardware component of the mobile initiator device, a radio frequency field in accordance with a first radio frequency field duty cycle designed to maximize detection success of the at least one passive near-field communication device;

    when no passive near-field communication device is available in the camping cell sitedetermining, by the mobile initiator device, a mobility state of the mobile initiator device; and

    controlling, by the mobile initiator device, based upon the mobility state, activation of the radio frequency field that is used to activate a passive near-field communications device so that activation of the radio frequency field is either in accordance with a second radio frequency field duty cycle designed to maximize battery efficiency of the mobile initiator device or the first radio frequency field duty cycle designed to maximize detection success of any passive near-field communications device.
