Abstract: An IP Packet Access Gateway (IP PAG) system manages an IP bearer path between communicating IP endpoints. The system includes an IP PAG having a first IP bearer connection termination for terminating a first bearer connection with a first IP endpoint, and a second IP connection termination or terminating a second bearer connection with a second IP endpoint. A call control entity is associated with the IP PAG and communicates call control instructions thereto. The call control instructions include instructions for logically concatenating the connections into an active IP bearer path extending between the first IP endpoint and the second IP endpoint. A bearer traffic IP packet handler in the IP PAG moves bearer traffic IP packet payloads over the active IP bearer path.

Abstract: Subscribers (103) are migrated from a first network (101) to a second network (115). Once the second network (115) is ready for traffic, connections from other networks (113) to the first network (101) are effectively transferred to the gateway mobile switching center (GMSC) (123) of the second network (115). All calls for the first network (101) and the second network (115) are directed to the GMSC (123) of the second network, which queries the home location register (HLR) (125) of the second network (115) for routing information. When a subscriber (117) is provisioned and activated at this HLR (125), the call is routed within the second network (115). When a subscriber (103) is not provisioned or activated at this HLR (125), the call is routed to the first network (101).

Abstract: A system and methods are provided for collecting, analyzing, and reporting data supplied on the report data stream of an electronic switching system or other generator of a report or log data stream or file. Local data storage facilities are provided to receive and store report data stream information for one or more switches. A centralized data storage and analysis facility receives the data collected by the local facilities. A parser parses the collected report data to select and reformat report items of interest according to predefined selection triggers. A post processing facility includes pattern identification and pattern classification components. The pattern identification component reads the parsed, selected report items and extracts a pattern comprising the selection triggers and function call addresses associated with each event. The pattern classification component determines whether the identified pattern for each event is old or newly encountered.
