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 non-transitory computer readable medium having computer executable instructions stored thereon for execution 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 by implementing steps comprising:

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 at 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 non-transitory computer readable medium of claim 1, wherein the IMEI uniquely identifies the mobile device.

3. The non-transitory computer readable medium of claim 1, wherein the computer executable instructions further comprise:

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

4. The non-transitory computer readable medium of 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 non-transitory computer readable medium of 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 non-transitory computer readable medium of claim 1, wherein the cellular telephony protocol message is configured in accordance with an unstructured supplementary service data message protocol.

7. The non-transitory computer readable medium of claim 1, wherein the cellular telephony protocol message is configured in accordance with a short message service message protocol.

8. The non-transitory computer readable medium of claim 1, wherein the cellular telephony protocol message is configured in accordance with a multimedia message service message protocol.
