Abstract

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.

Claims

1. A method in a network for indicating to a network component that a circuit switched (CS) call with a mobile device and a packet switched (PS) communication session originate from the same mobile device, the method comprising at the network:

receiving a first International Mobile Equipment Identity (IMEI) originating from a mobile device having sent the first IMEI in an information element of a cellular telephony protocol message;

receiving a Session Initiation Protocol (SIP) message to the network, the SIP message including a second IMEI in a format of a Unified Resource Name (URN) in an instance identifier (ID) contained within the SIP message; and

determining that the CS call and the PS communication session originate from the mobile device when the first IMEI matches the second IMEI.

2. The method according to claim 1, wherein the IMEI uniquely identifies the mobile device.

3. The method according to claim 1, further comprising:

receiving the SIP message from the mobile device at a PS network of the network.

4. The method according to claim 1, wherein the IMEI uniquely identifies the mobile device as a participant in the CS call over a cellular network of the network and as a source in the PS communication session over a PS network of the network.

5. The method according to claim 1, wherein the CS call comprises a voice call and the PS communication session comprises at least one of streaming video data and a Voice over IP (VoIP) communication.

6. The method according to claim 1, wherein the cellular telephony protocol message is configured in accordance with an unstructured supplementary service data message protocol.

7. The method according to claim 1, wherein the cellular telephony protocol message is configured in accordance with a short message service message protocol.

8. The method according to claim 1, wherein the cellular telephony protocol message is configured in accordance with a multimedia message service message protocol.

9. A network for indicating to a network component that a circuit switched (CS) call with a mobile device and a packet switched (PS) communication session originates from the same mobile device, the network being configured to:

receive a first International Mobile Equipment Identity (IMEI) originating from a mobile device having sent the first IMEI in an information element of a cellular telephony protocol message;

receive a Session Initiation Protocol (SIP) message to the network, the SIP message including a second IMEI in a format of a Unified Resource Name (URN) in an instance identifier (ID) contained within the SIP message; and

determine that the CS call and the PS communication session originate from the mobile device when the first IMEI matches the second IMEI.

10. The network according to claim 9, wherein the IMEI uniquely identifies the mobile device.

11. The network according to claim 9, wherein the network is further configured to:

receive the SIP message from the mobile device to a PS network.

12. The network according to claim 9, wherein the IMEI uniquely identifies the mobile device as a participant in the CS call over a cellular network of the network and as a source in the PS communication session over a PS network of the network.

13. The network according to claim 9, wherein the CS call comprises a voice call and the PS communication session comprises at least one of streaming video data and a Voice over IP (VoIP) communication.

14. The network according to claim 9, wherein the cellular telephony protocol message is configured in accordance with an unstructured supplementary service data message protocol.
