Abstract
Systems and methods provide virtual CSCFs in an IMS system. The Virtual CSCFs may be virtual S-CSCFs or virtual P-CSCFs. A master virtual CSCF may be used to distribute subscriber data and initial filter criteria to the virtual CSCFs in a group. Thus one of multiple servers may be used for processing call sessions for the same subscriber, thereby avoiding overloading a particular CSCF in an IMS system.
