Exchange and Use of Globally Unique Device Identifiers for Circuit-Switched and Packet Switched Integration

A telephony-enabled device comprising a call processing function for enabling packet switched communications with another telephony-enabled device by executing steps comprising:

• obtaining a first GUDI (globally unique device identifier);
• and
• sending the first GUDI to the another telephony-enabled device via a first circuit switched message;
• wherein if a second GUDI is received from the another telephony-enabled device, then packet-switched data is routable to the another telephony-enabled device using the second GUDI and packet-switched data is routable to the telephony-enabled device using the first GUDI.

A computer readable medium having computer executable instructions stored thereon for execution on a telephony-enabled device so as to enable packet switched communications with another telephony-enabled device by implementing steps comprising:

• obtaining a first GUDI (globally unique device identifier);
• and
• sending the first GUDI to the another telephony-enabled device via a first circuit switched message;
• wherein if a second GUDI is received from the second telephony-enabled device, then packet-switched data is routable to the another telephony-enabled device using the second GUDI and packet-switched data is routable to the telephony-enabled device using the first GUDI.

A wireless device comprising a call processing function for enabling packet switched communications with a second telephony-enabled device by executing steps comprising:

• obtaining a first GUDI (globally unique device identifier);
• and
• sending the first GUDI to the second telephony-enabled device via a first circuit switched message;
• wherein if a second GUDI is received from the second telephony-enabled device, then packet-switched data is routable to the second telephony-enabled device using the second GUDI and packet-switched data is routable to the wireless device using the first GUDI.
