EXCHANGE AND USE OF GLOBALLY UNIQUE DEVICE IDENTIFIERS FOR CIRCUIT-SWITCHED AND PACKET SWITCHED INTEGRATION |
摘要 |
According to one aspect, a system and method of exchanging GRUUs (Globally Routed User Agent URI (Uniform Resource Identifier)) between a first telephony-enabled device and a second telephony enabled device using a circuit-switched message is provided. Once exchanged, the telephony enabled devices can exchange SIP (session initiated protocol) communications routed by the GRUUs. Any one of the telephony-enabled devices can add a media component to the SIP communications. According to another aspect, a system and method of generating GRUUs is provided. According to another aspect, a system and method of handing off communications to a packet switched network from a circuit switched network is provided. |

1. A method in a first telephony-enabled device of enabling packet switched communications with a second telephony-enabled device, the method 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 first telephony-enabled device using the first GUDI. |
