ABSTRACT:
A mobile station is identified by a mobile directory number (MDN) and by a mobile station identifier (MSID). To communicate with a packet-switched network, the mobile station transmits its MSID, and a network access server, such as an interworking function (IWF), assigns an IP address to the mobile station and correlates the IP address with the MSID. A gateway receives a communication from the mobile station that includes the mobile station's IP address. The gateway identifies the mobile station's MDN based, at least in part, on the IP address, a correlation between IP address and MSID, and a correlation between MSID and MDN.
