  • Exchanging control codes between SIP/IMS and UPnP network elements
    Patent number: 8775683
    Abstract: Method for exchanging control codes between a SIP (Session Initiation Protocol) enabled first network element (1) of an IMS (IP Multimedia Subsystem) network (2), e.g. a mobile terminal connected to such network, and a UPnP (Universal Plug and Play) enabled second network element (3) of a UPnP enabled network (4), both networks being interconnected by an IMS/UPnP interface (5). The first network element (1) addresses a request to a SIP/SIP interface (6), using an address which conforms to the Wildcard PSI (Public Service Identity) format and comprising a PSI address part A which is valid for PSI addressing, and a wildcard address part A?. Then the PSI address part A is converted, in the SIP/SIP interface (6), into a valid SIP URI (Universal Resource Identifier) address B assigned to die IMS/UPnP interface (5), while the wildcard address part A1 is converted into an address parameter B1, pointing or assigned to the second network element of the UPnP enabled network.
