1. A computer-implemented method for facilitating Call Detail Record (CDR) billing in a converged cellular system and an IP-based wireless system, the method comprising:

  • receiving a registration request over the IP-based wireless system from a handset that is capable of using the cellular system and the IP-based wireless system and is identified by a wireless identifier;

    selecting an IP-based wireless cell identity with a gateway node referenced by the wireless identifier after the registration request is received;

    overloading at least one existing field from a cellular call detail record with the IP-based wireless cell identity such that the overloaded cellular call detail record field corresponds to an IP-based wireless call;

    identifying a call request from the handset over the IP-based wireless system; and

    communicating the overloaded cellular call detail record to a switch for the identified call request,wherein the overloaded cellular call detail record reflects, at least in part, a handover from the IP-based wireless system to the cellular system or from the cellular system to the IP-based wireless system.
