Patent ID: 7979069

Claim:
A mobile device for communicating with a base station according to a communication protocol, the communication protocol comprising a first message for signaling a readiness of the base station for a normal login operation of the mobile device with the base station and a second message for signaling a readiness of the base station for a temporary login operation of the mobile device with the base station, comprising: a receiver, which is formed so as to receive a message of the communication protocol from a base station; an interpreter for interpreting the message based on the communication protocol, the interpreter being formed so as to differentiate the signaling of the readiness of the base station for the normal login operation from the signaling of the readiness of the base station for the temporary login operation; a processor, which is formed so as to perform the temporary login operation with the base station when the readiness of the base station for the temporary login operation is signaled; a first memory for storing a system configuration including normal login information for the normal login operation and a second memory separate from the first memory for storing temporary login information for the temporary login operation; and a terminator for terminating the temporary login operation of the mobile device, the terminator being formed so as to terminate the temporary login by a command, by a time limit or by switching off the mobile device and to delete the temporary login information in the second memory; wherein the interpreter is formed so as to search, in a message received, for an escape code defined by the communication protocol, the escape code indicating an application not defined by the communication protocol; and the interpreter is formed so as to interpret the message so that a following region of the data stream is evaluated when the escape code is recognized, and, in the event of a default occupancy of the following region, to activate the processor so that it starts the temporary login operation, or to already activate the processor to start the temporary login operation when the message comprises the escape code.
