ABSTRACT:
A system for providing information services via broadcast messages to mobile stations and other devices. The broadcast messages are encrypted prior to being communicated to devices within a geographic area. A client application retrieves cryptographic keys associated with the information services to which a customer is subscribed. When the mobile station or device receives encrypted broadcast messages, the client application determines if it has the cryptographic key to decrypt the message. If so, the information contained in the message is displayed. If not, then the message is ignored by the mobile station. The information may be used to provide or retrieve near real time information from devices to provide such services as traffic alters, fleet management, etc.
