ABSTRACT:
An intermediary system that seamlessly evolves the 2G/2.5G storage mediums to the 3G entities (e.g., a logical HSS) and provides subscriber data to 3G services such as IMS, from legacy data sources. An Intermediary Query Manager (IQM) is provided that functions as intermediary/broker system, and supports defined standard 3GPP interfaces specific to the IMS system (utilizing the existing storage medium servicing the PS domain) and also allows the continued support of the 2G/2.5G interfaces to 2G HLRs (servicing the CS domain). The IQM provides the capability to leverage usage of the current subscriber databases without requiring extraordinary efforts to migrate subscriber information to a new dedicated HSS element. The IQM provides data from multiple sources and processes requests necessary to fulfill these requests. The IQM can look like a MSC (Mobile Switching Center), VLR (Visitor Location Register), and/or SCP (Service Control Point) to the HLRs depending on the type of queries.
