  • a common mobile radio station is controlled using software, generally program codes.
  • the software is usually loaded by the mobile radio station, installed there and executed in order to ensure different functionalities in the mobile radio station.
  • the radio properties of the mobile radio station are controlled by software (for example the frequency bands to be used, the transmission power to be used or the modulation method to be used) or other properties. These include, for example, the type of signaling, different strategies for frequency selection or different services offered, that is to say provided.
  • a mobile radio station generally a communication terminal
  • the functionality of a mobile radio station can thus be specifically changed or expanded by loading and then installing appropriate software.
  • it In order to prevent manipulation of the mobile radio station by unauthorized third parties, it must be ensured that the mobile radio station only accepts, installs and runs software that comes from a reliable provider and for which it is guaranteed that the software has not been modified.
  • software can be transmitted to the mobile radio station via any unsecured channels, in particular via a radio channel.
  • software can be obtained from a personal computer, a generally accessible computer that is installed, for example, at an airport or a train station, or another mobile radio station, for example, via an air interface, that is, via a radio link, or via a connection cable via a cable.
  • a method for reliably providing software should advantageously not be dependent on specific assumptions about the type of software distribution.
  • Execution environment for applications on a mobile radio station are used, or to use the technologies also used on the Internet, such as the so-called Microsoft Authenticode and Netscape Object Signing.
  • the software uses a digital signature and possibly other data for verification the digital signature are used.
  • a digital signature uses the principle of asymmetrical cryptography, in which a private key and a corresponding public key, which together form an asymmetrical key pair, are used.
  • a certificate of the respective public cryptographic key is used to securely certify a link between the public cryptographic key and the name of the person or organization to which the public key belongs. This ensures that the key pair used, consisting of the respective private cryptographic key and public cryptographic key, is reliable.
  • the invention is therefore based on the object of specifying an improved method for installing or deinstalling software in a mobile radio station, with which it is ensured that the mobile radio station is compatible with the requirements of the current mobile radio network. This object is achieved with the method and the subscriber station in accordance with the independent claims.
  • the subscriber station receives a request to install or uninstall the program code from a request unit, an authorization of the request unit for requesting to install or uninstall the program code is checked and this is done Installation or deinstallation only if the check shows that the request unit is authorized to request the installation or deinstallation of the program code.
  • the invention makes it possible for each subscriber station and each radio communication system to be individually determined which request units are authorized to request an installation or deinstallation of a program code, ie to initiate the installation or deinstallation of the program code.
  • program codes are not installed or uninstalled in subscriber stations without authorization, for example, by the operator of a radio communication system.
  • Program codes which have been authenticated, for example, by a digital signature and whose installation on the subscriber station is in principle possible can change the functionality of the subscriber station in such a way that the subscriber station no longer functions in the current radio communication system and / or the trouble-free operation interferes with other subscriber stations.
  • the invention also makes it possible to control the installation of authenticated program codes, ie in particular the installation of program codes which are undesirable in the current radio communication system can be prevented. It is therefore expedient for the authorization to be checked by authenticating and / or authorizing the requesting unit.

  • the access rights of a request unit expediently depend on which functionality influences the subscriber station during installation or deinstallation, i. H. to be changed.
  • Access to a functionality that changes the radio transmission method of the subscriber station should, for example, only be granted to request units that can be assigned to the current radio communication system or have a corresponding authorization for this radio communication system. It is therefore advantageous if the authorization check takes into account which functionality of the subscriber station would influence the installation or deinstallation of the program code.

  • One embodiment provides that the program code is stored in the subscriber station before the authorization is checked. This has the advantage that the program code is also stored in the subscriber station if the authorization check is negative. The program code uss is then not transmitted when the installation is requested again, for example by another requesting unit, but can be installed immediately after a positive check of the request. Of course, only program codes that can be authenticated and whose integrity has been checked are saved.
  • An alternative embodiment provides that the program code is only loaded into the subscriber station after the authorization has been checked.
  • a connection resource between the subscriber station and a unit providing the program code for example a corresponding server computer or the requesting unit, is only occupied with data bits of the program code if it is actually to be installed.
