  • Method and system for routing of a USSD message
    Patent number: 6330445
    Abstract: A system and method are provided for routing of a USSD message directly from an MSC/VLR to an external node. When a mobile station user enters a service code which the mobile station does not recognize as being associated with a known supplementary service, the mobile station forms a USSD message containing the service code which is sent to a MSC/VLR. If the MSC/VLR determines that the service code is one that is associated with an application residing in an external node, then the MSC/VLR routes the USSD message directly to the external node. Various methods and techniques can be used to provide the address of the external node to the MSC/VLR.
