Method for accessing data processing device, involves establishing communication channel between terminal and processing device, when digital certificate from terminal corresponds with digital certificate from switching device

摘要

The method involves receiving an identification signal comprising identification code from a mobile terminal (M) by switching device (S). A communication end point of data processing device (P) is selected and assigned to the terminal through which a connection establishment request is signaled to the terminal. A digital certificate along with the request is transmitted from the terminal and a communication channel (KK) is established between the terminal and processing device, when received digital certificate corresponds with digital certificate from switching device. Independent claims are included for the following: (1) switching device; and (2) program unit for mobile terminal.
