The present invention relates to a point code emulation apparatus and method for dividing a Common Channel Signaling System No. 7 (or SS7) signaling network into two or more networks. The point code emulator is adapted to receive TCAP messages from two or more subnets and converts, for the messages crossing over the subnets, the information of the TCAP messages, including originating point code, destination point code, and transaction identifier, (and optionally, calling party number and called party number), and forwards to the other one of the two or more subnets. Correspondence among the two or more subnets may be provisioned by an authorized user of the system, may be learned automatically by the system based on ISUP message correspondences or previous TCAP transactions, or may be automatically discovered by the system broadcasting messages to nodes in the destined one of the two or more subnets.

Methods and apparatus for routing TCAP messages

Method and apparatus for sharing TCAP traffic load

Systems and methods system for managing data objects that support the personalization of mobile communications services are provided. The system includes one or more databases that contain subscriber data, such as usage, or state information related to the subscriber. For one or more of the databases within the system, a database federator and a distributed object repository having multiple nodes is provided. The nodes are used to store data objects and duplicate data objects. Data objects may be distributed to the nodes based on, a hashing algorithm. Additionally, graceful redundancy degradation of stored duplicate objects is provided. Further, time-based triggering of duplicate objects stored within separate nodes is provided.
