ACCESS TO DATA FROM MOBILE DEVICES

摘要

A mobile device (1) communicates with an applications server (6) residing outside of its mobile network (2) in real time. A data payload is transmitted in a message with a single USSD network facility request string associated with all applications. A HLR/VLR (3) immediately forwards the message to an access server (4) within the network (2). The access server (4) in turn immediately routes the request to the applications server (6). The applications routing is determined by the message payload and not the service code content. This allows the network facility request mechanism to be used as a generalised data transport pipe for complex point-to-point interactions between a mobile device and an external server. Complexity of the interactions is only limited by the XML payload of the messages or string of messages.
