Abstract: A method for improved determination of the position of a user device in a mobile-radio network is provided. In combination with adjacent, second user devices, the method is intended to achieve a relatively-accurate positioning even if only a relatively-inaccurate positioning method is available for the user device itself, especially if the latter is disposed inside a building. An absolute position of a second user device is determined with a first position-determining method. A relative position of the first user device relative to the second user device is then determined with a second position-determining method. Finally, the absolute position of the first user device is determined on the basis of the absolute position of the second user device and the relative position of the first user device relative to the second user device, wherein the first and the second position-determining methods are different methods.

Abstract: A method of recognizing a synchronization message from a wireless telecommunications device comprising the steps of: dividing a series of known identification codes into a plurality of sections; processing and storing the sections of the known identification codes; dividing a signal received from the wireless telecommunications device into a plurality of sections; processing the sections of the received signal; and comparing the sections of the received signal with the sections of the known identification codes.

Abstract: A base station of a mobile communication network is connected to a core network and is operable in a normal mode and in a direct mode. The base station detects a request originating from a first user equipment to communicate with a second user equipment. The first user equipment is in direct reach of the base station. The base station establishes a communication link between the first and the second user equipment, and checks if the second user equipment is also within direct reach of the base station. The base station operates the communication link in direct mode, if yes, and operates the communication link in normal mode, otherwise.
