Mobile telephone system and radio station

摘要

Mobile radio station for data communication radio other stations, with siguientesequipos: - a microprocessor (10) for controlling the radio station and communication data, - a nonvolatile memory (18), - a bus addresses (16), through which are linked together non-volatile memory (18) and elmicroprocesador (10), - a computer (24) through which the non-volatile memory (18) electrically erasable and writable denuevo in that- in a first memory segment (20) of the nonvolatile memory (18) is memorized a decontrol program (84, 90) to be processed by the microprocessor (10) for controlling the radio station, starting the program control (84, 90) in a direction (initial direction) controlling elmicroprocesador (10) after a start or restart of the mobile radio station, - in a second memory segment (22) includes a control program load ( 86, 86 ') has deprocesar the microprocessor ( 10) when it has loaded a new control program by radio nonvolatile memoryand (18), characterized because- addresses arriving on the address bus can be modified by a logic module (36), - that the microprocessor (10) , after presenting a load command, controls the logic module (36) modifies the address such that WILL arriving on the address bus to an address value under which estámemorizado control program load (86), because y- microprocessor (10) after processing the control program load (86), deactivates the módulológico (36) to not modify the addresses arriving on the address bus (16).
