Abstract: Systems and methods of mobile communication roaming where a subscriber's home network and a roaming network used by the subscriber do not have a roaming agreement. Roaming between an alliance of coordinated operators having bilateral roaming relationships and operators who do not have roaming agreements with the alliance is provided. By subscribing to the system, a non-alliance operator can gain roaming access to alliance networks having existing bilateral roaming relationships. An authentication message is received from a roaming network in which a subscriber is roaming and the message is authenticated if there is a roaming relationship. The authentication message is forwarded to the home network via an alliance network and responsive to the indication that the authentication message was received at a roaming network, roaming transactions are enabled for the subscriber within the roaming network.

Abstract: A system and method of mobile communication roaming where a subscriber's home network and a roaming network used by the subscriber do not have a roaming agreement. The roaming network sends a “Send Authentication/Parameters” request to the home network via an intelligent roaming system on or attached to the backbone. The home network sends an authentication response to the “Send Authentication/Parameters” request from the home network to the roaming network via the backbone and intelligent roaming system. The roaming network sends a “Update Location” request from the roaming network to the intelligent roaming system. The visitor locator register (VLR) address in the “Update Location” request is replaced with the VLR address of the intelligent roaming system to create a modified update request. The modified update request is sent from the intelligent roaming system to the home network.

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: The present invention relates to a network-based method and system to control and enable seamless roaming across various cellular network types. The system provides dynamic mapping, processing and conversion of messages to enable seamless communication across various cellular network types. Use of roaming enabled services in non-Roaming Enabled Networks is achieved by integrating this system with the non-Roaming Enabled Network.
