SYSTEM AND METHOD FOR DETERMINING WHEN A CSCF SHOULD ACT LIKE I-CSCF OR LIKE S-CSCF

摘要

The present invention proposes that network system (2) include the first network element and the second network element (3), second network element is suitable for operating at least two different modes, wherein the first network element (2) is to adapt to be sent to the second network element, and the second network element (3) is that adaptation includes message in response to information into Setting pattern and indicates whether to execute specific program and/or complete. Therefore, whether the second network element sets its mode and must be performed dependent on the identical processing position requests of process, or need not execute, or, whether no matter process has been performed. Network element can be the state (CSCF) of call control function.
