A procedure and a data communication system in which a service provider provides to a remote user of a service a set of expendable passwords for use by the user in accessing the service via a telecommunication and/or data network. The user's terminal device is provided with means for automatically transmitting a password at log-on to the service, and a server to which the terminal device sets up a connection includes means for identifying the password and for allowing or denying access to the service on the basis of the supplied password. The terminal device further includes means for storing a set of passwords and for selecting, at log-on to a predetermined service, the correct password from the stored set of passwords for automatic addition of the password to a connection setup signal transmitted from the terminal device to the server.

Method and apparatus for remotely accessing a password-protected service in a data communication system

A method and system for changing a subscriber profile on the basis of the detected or known identity of the base station currently serving the terminal equipment of that subscriber in a mobile communication network. A permanent and unique identity parameter or designation is created and assigned to each base station of the network, and is broadcast by each respective base station to all subscriber terminal equipment currently in its communication coverage area or region. Changing of the subscriber profile on the basis of subscriber movements within the network is accomplished with enhanced flexibly and ease and at lower cost than heretofore possible.

Method and system for changing a subscriber profile based on the identity of a base station serving the subscriber terminal

In the present invention, a method for performing a handover procedure for a movable mobile station communicating in a communication network is disclosed. The communication network includes a plurality of base transceiver stations adapted to communicate with mobile stations within its coverage area. The method includes processing location information related to the mobile station and position information related to the base transceiver stations. The method also includes deciding, based on the result of the processing, whether a first handover condition is fulfilled and designating a next base transceiver station in the network to communicate with the mobile station. When the first handover condition is fulfilled, a handover of the mobile station from the current base transceiver station to the next designated base transceiver station is triggered. A corresponding device for controlling handover is also disclosed. Base transceiver stations that do not permanently transmit a broadcast control channel or base stations which can be turned off when no subscribers are within the coverage area may be used.

Method and device for performing handover using location information

A system for changing the service profile of a mobile subscriber includes a location part ( ), a evaluation part ( ) and a subscriber connection exchange part ( ). Besides these, the home location register contains such individual subscriber connections for the subscriber, which have a different service profile. The duty of the location part is to find out the location of the mobile station in the network and to give location information to the evaluation part. The information may be e.g. a location area identity, cell identity or switching centre area identity which is used in the public land mobile network. The evaluation part checks to find out whether the location information has changed compared with the location information received earlier. If it has, it searches the memory for the corresponding location information and compares the connection information in the record with the current connection information. If the connection information is identical, the process remains waiting for new location information. If the connection information is different, the evaluation logic deduces that the connection must be exchanged for a new one and a connection exchange operation must be started. This may take place so that the connection exchange part disconnects the mobile station from the network and reconnects to the network using a new MSISDN number. The algorithms and encryption keys relating to this number it fetches from the memory. The network fetches from the home location register the subscriber information relating to this MSISDN number and along with this also the service profile relating to this number. It is most advantageous to implement the location part, the evaluation part and the subscriber connection exchange part on the subscriber identity module (SIM).
