Abstract: The present invention provides a Universal Signaling Point (USP) that acts as a liaison between a call signaling network and a number of switching entities, which support lines, trunks, or a combination thereof. During a transition of the lines or trunks from a donor entity to a host entity, call signaling between the host and donor entities and the SS7 network is routed through the USP. When transitioning the lines or trunks from the donor entity to the host entity, call signaling messages intended for the donor entity are routed to either the donor or host entity, whichever actually supports the lines or trunks. The USP is provided information indicative of whether a line or trunk has been transitioned to the host entity. The USP can compare information provided in the call signaling message with the transition information and route the message to the appropriate donor or host entity.

Abstract: A system for implementing a real-time distributed, hierarchical database uses a proxiable protocol. The system includes a first proxy server for receiving a first proxiable protocol message from a first network element. The first proxy server performs a first database lookup based on information contained in the first message. If the first proxy server does not obtain the requested information, the first proxy server formulates a second proxiable protocol message and forwards the message to a second proxy server. A second proxy server receives the second message and performs a second database lookup based on information contained in the second message. The second proxy server sends the results from the second database lookup to the first proxy server and the first proxy server forwards the results to the database user.

Abstract: Method and apparatus for messaging between disparate networks. A service control gateway (SCG) provides the capability to extend advanced intelligent network (AIN) services transparently between circuit switched and packet networks. In one embodiment, the invention works by translating signaling system 7 (SS7) transaction capabilities application part (TCAP) messages into session initiation protocol (SIP) INVITE messages. SIP messages, which may be responses to the translated messages referred to above, are translated back into TCAP messages. Data from messages is stored in an interaction database, a data structure maintained at the SCG. The SCG uses the interaction database to properly format translated messages for each network.
