  • Coordination of user information across session initiation protocol-based proxy servers
    Patent number: 8300644
    Abstract: An improvement in the design and operation of telecommunications networks is disclosed, in which when a calling party's telecommunication terminal does not know the address of the called party's terminal, the calling party's telecommunication terminal contacts its home Session Initiation Protocol (SIP) proxy server (or “home proxy”). Upon determining that it does not already have the called party's address, the home proxy employs one or more techniques in order to obtain that party's address, as well as to retain that address. The first technique of the illustrative embodiment features the usage of a registration event package, which includes SIP-based subscribe and notify mechanisms. The second technique of the illustrative embodiment features the usage of a data distribution service, which operates in a data distribution layer in contrast to utilizing, for example, a SIP mechanism.
