AN EXTENSIBLE SYSTEM AND METHOD TO BRIDGE SIP AND UPNP DEVICES
摘要
Embodiments of the invention generally provide a method and apparatus for bridging session initiation protocol and universal plug and play devices. One embodiment of the invention specifies a method that enables legacy session initiation protocol (204) and universal plug and play devices (202) to communicate with each other (i.e., to access devices), where the term "legacy" is defined to mean IETF RFC 3261-compliant for session initiation protocol devices, and DLNA 1.0-compliant for universal plug and play devices. The method enables inter-working between the session initiation protocol and universal plug and play devices without requiring changes to the legacy devices. One embodiment of the invention is a transparent software bridge (206) that enables these features.
