Abstract: A virtual operator and method for performing authentication and service translation. The virtual operator assigns first and second identifiers to subscribers. The virtual operator updates the second identifier when the service provider corresponding to the second identifier changes. When the virtual operator receives a request for authentication, the virtual operator forwards the authentication request to a serving network for authentication. When the virtual operator receives a service request, the virtual operator selects, using network optimization criteria, a network to provide the requested service. The virtual operator translates network protocols when the network forwarding authentication or service request uses a network protocol different from the network performing authentication or the requested service.

Abstract: A system and method of enhancing content of at least one message sent by a source device to at least one destination device over at least one network. The system is operative to receive a message over a network, in which the message has content associated therewith. The system analyzes the content of the received message, and selects additional information based upon the content of the received message. The system inserts the selected information into the message, and then transmits, over the network, the message and the selected information to a destination device. The selected information can include at least one advertisement.

Abstract: A virtual operator and method for rating a charge for connecting to a network from a virtual operator and facilitating analysis of profitability of using a network. The virtual operator receives a Charge Detail Record in real time from a network the virtual operator is using for a service. The virtual operator calculates the current utilization of the network's resources using the received CDR. The virtual operator calculates a rate for connecting to the network, the rate corresponding to the virtual operator's current utilization of the network's resources. The virtual operator further calculates a cost for providing the service, the revenue for providing the service, and the profit based on the difference between the revenue for providing the service and the cost for providing the service.
