Patent ID: 7916685

Claim:
A system for supporting database access in Internet protocol (IP) multimedia subsystem (IMS) network environment, the system comprising: at least one call state control function (CSCF) entity for generating subscriber-related queries according to an abstracted profile (AP) protocol; and an abstracted profile server (APS) configured to obtain subscriber information from each of a plurality of subscriber information databases including a database implemented by an IMS network entity and a database implemented by a legacy network entity, the APS for receiving a CSCF-generated, subscriber-related query and for: gathering subscriber information related to the CSCF-generated, subscriber-related query from at least one of the subscriber information databases using a native protocol of the at least one subscriber information database; generating a reply message for the CSCF-generated, subscriber-related query based on the gathered subscriber information; and forwarding the reply message to a respective CSCF that generated the CSCF-generated, subscriber-related query, the reply message being forwarded according to the AP protocol, wherein the APS is adapted to gather subscriber information related to the CSCF-generated, subscriber-related query from the at least one subscriber information database using a native protocol of the subscriber information database by generating, in response to a CSCF-generated, subscriber-related query, at least one corresponding query to the at least one subscriber information database using a native protocol of the at least one subscriber information database and receiving respective replies to the at least one corresponding query.
