Abstract: A system provides a service to mobile devices that permits the mobile devices to substantially avoid roaming charges while roaming in visited networks. A temporary subscriber identity (TSI) server receives a TSI request message from a TSI client operating on a roaming mobile device. If available, a temporary service identity is returned to the TSI client, which registers the mobile communications device with a specified service provider as a home subscriber using the temporary service identity.

Abstract: A method, apparatus and system for reconfiguring communications call paths enables more efficient use of communications network resources and enhanced service offerings. A plurality of feature control points (FCPs) located in a plurality of different types of communications carrier networks are controlled by a single call service node (CSN). The CSN receives a report from a FCP each time the FCP receives a call control signaling message. The CSN uses the reports to map the call path, so that when a connection change request is received, the CSN can select which of the FCPs to use to effect the requested change based on predetermined criteria.

Abstract: A method and apparatus for efficiently utilizing resources in a switched telephone network by providing call treatment at the closest available resource to the calling party preventing holding up network connection through to the terminating location if resources are not available at call termination equipment to handle a call. The selected calls are locally parked pending the availability of service termination resources to handle the call. The availability of service resources at the termination is determined before a selected call is extended through the network. Advantageously while the call is parked call treatment discrimination can be performed.

Abstract: A method and system for correlating information retrieved from a data network, with a telephone call initiated by an initial address message (IAM) at a multi-line facility, such as a call center or a voice access server (VAS), hinges on extracting an identifier string inserted into the user-user-interface field of the IAM, and accompanying the information. The information is used to perform an enhanced service feature which may include aiding the selection of an internal line at call center's call distributor, or the selection and customization of delivery of a service feature, at a VAS. The information may also be displayed at a display terminal associated with a call center agent handling the call.
