Abstract: A data transfer interface for importing data from a source system to a target system, including a source data adapter having an attribute definition transcriber for generating transcribed data, and a target data adapter having a data format converter for converting the transcribed data from a first format to a second format. The data transfer interface may include a data validator to ensure that the user data selected for importation is valid before the data is transcribed. The source data adapter and the target data adapter may be configured for use with a communications architecture that allows the source data adapter and the target data adapter to receive and transmit user data as events on a data communications network.

Abstract: A network access point for locally processing an access request is configured to include an information bus, an access event publisher, and at least one local cache having at least one user record. The access event publisher publishes at least one network access event on the information bus during the processing of the access request. The first local cache is coupled to and is responsive to the network access event by updating the user record according to information contained by the network access event if the information includes a home access point ID that corresponds to the first local cache. The network access point may be part of a communications system having a mother cache. The mother cache is coupled to the first local cache and includes user records of subscribers supported by the communications system.
