摘要:
A system for derivation and provision of anonymised cellular mobile network data for population density and mobility report generation can be implemented on a computer, e.g. in a data warehouse system. The system includes effective anonymisation measures to protect the privacy of the mobile network customers. It comprises a load extractor and a database production environment, where the load extractor is connected with the mobile network to receive and anonymise traffic data from a mobile communications network, and where the production environment is set up to allow a third party to query the traffic data for the purpose of population density and mobility report generation. The production environment of the system presents itself as a “black box,” which can be operated by the third party only via specific interfaces. Thus, the system can be operated by a third party without compromising the privacy of the mobile network users.

The techniques described herein relate to a method for the localization of a terminal device by a localization unit that is configured to locate the terminal device on the basis of radio signals received in the terminal device from radio access points. In the method, the activation of the localization is controlled on the basis of the radio signals as a function of an evaluation of radio signals from at least one radio access point that have been detected in the vicinity of the terminal device by at least one receiving unit, and/or as a function of information about installation sites of radio access points. Moreover, the techniques described herein relate to a system that is suitable for carrying out the method.

The technique described herein relates to a method for transmitting data to an identification module in a mobile terminal device that can be connected to a mobile telecommunications network, making use of an OTA server that has a database with security information for a plurality of identification modules and that also has a first interface for transmitting secured information, especially OTA messages, to the identification modules. The data is secured in the OTA server by security information stored in the database, and the secured data is transferred via a second interface of the OTA server to a data center that is connected to the OTA server. The data is transmitted to the identification module by the data center. Moreover, the technique described herein also relates to a system for carrying out the method.

There is provided a system for social interactions between users. The system may include a plurality of network nodes connected in a network, each node comprising a representation of at least one assigned user. The exemplary system comprises a first node assigned to a first user, the first node being adapted to generate an activity upon an execution of an action of the first user with a data object in interaction with the first node. The activity may describe the action in a predetermined format and may include a representation of the data object. The first node may be further adapted to link the activity to at least one second user and to communicate the activity to at least one second node to which the second user is assigned.

Device and method for recognizing wanted and/or unwanted telephone calls of a telephone user as a function of the user's behavior. The device has an interface to at least one telephone of the user and an interface to at least one media terminal. A mechanism determines the input of a telephone call on the user's telephone. An examining mechanism establishes a spatial relationship between the user's telephone and the media terminal. A detection mechanism detects the activation state of the media terminal. A tapping mechanism taps the media content playing on the media terminal at the time point of the input of a telephone call on the user's telephone. A comparison mechanism compares the media content during an incoming call on the user's telephone with the media content of Event Files of a User Profile stored in a storage mechanism. A determining mechanism determines whether a call is wanted.

A method for the switchover of a mobile terminal device from a first radio network of a mobile radio system to a second radio network is described. The switchover is carried out on the basis of a CS fallback mechanism, and whereby, on the basis of the switchover, the mobile terminal device logs on to a base station of the second radio network in order to establish a connection. In conjunction with the log-on, the mobile terminal device transmits a notification pertaining to the CS fallback mechanism to the base station, and the base station registers the log-on of the terminal device as a function of the notification. Moreover, a base station and to a mobile terminal device for carrying out the method are also described herein.
