1. A method, comprising:

  • transmitting, by an apparatus, a connection request including a random device address of the apparatus, to another wireless device over a first wireless carrier and establishing a connection with the other wireless device using the random device address;

    establishing, by the apparatus, pairing with the other wireless device to establish a secure relationship with the other device over the first wireless carrier, wherein establishment of the secure relationship comprises generating one or more encryption keys for link encryption;

    transmitting, by the apparatus, over the first wireless carrier, a device address of the apparatus associated with the paired secure relationship, the device address of the apparatus encrypted under at least one of the one or more encryption keys to provide authentication that it is the device address of the apparatus, to enable the other device to derive from the authenticated device address of the apparatus, an access code configured to access the apparatus over a second wireless carrier, the pairing providing the device address of the apparatus to the other device;

    receiving, by the apparatus, wireless paging messages over the second wireless carrier from the other wireless device, the wireless paging messages being addressed to the apparatus with the device access code of the apparatus, wherein the device access code is derived by the other wireless device from the device address transmitted by the apparatus over the first wireless carrier during pairing; and

    establishing, by the apparatus, a wireless connection over the second wireless carrier with the other wireless device, based on the device access code derived by the other wireless device from the device address transmitted by the apparatus over the first wireless carrier during pairing.
