1. An apparatus, comprising:

  • a service node of a macro network operable to;

    provide an authentication, authorization, and accounting (AAA) proxy for a micro wireless network and the macro wireless network;

    receive, from an access point associated with the micro wireless network, a request to authenticate the handover of a wireless session from the macro wireless network to the micro wireless network;

    receive AAA data from an access point of the micro wireless network during layer-two authentication;

    manage the authentication of the wireless session using the AAA proxy; and

    in response to the authentication, extract the mobile station identifier from the request, determine that the wireless session already exists, re-anchor a virtual path associated with the wireless session to the access point associated with the wireless network, and determine whether the wireless session is a direct access call session or a mobile Internet Protocol (IP) session.
