Abstract: A system and method of providing voice and data feature interaction in a Time Division Multiple Access (TDMA) radio telecommunication network having a data network overlay. An incoming voice call is established with a called mobile station (MS) when the called MS is operating in a data mode. An indicator is set in the called MS's user profile indicating that the called MS is operating in the data mode. The called MS is notified through the data network overlay that the incoming voice call is waiting. If the call is accepted, it is delivered to the called MS. The system may also establish an incoming data call with the called MS when the called MS is operating in a voice mode. A Short Message Service message center notifies the called MS that a data call is waiting. If the call is accepted, it is delivered to the called MS.

Abstract: The invention relates to a device and a method for reducing emissions in catalytic converter exhaust systems for a vehicle provided with a combustion engine. The invention comprises a control unit adapted to control the air-fuel being fed to the engine so that a high concentration of hydrogen is generated in the exhaust gas during start-up of the engine. Furthermore, secondary air is supplied downstream of the engine during cold starting thereof for foaming a gas mixture with the exhaust gas. This gas mixture is oxidized, so that heat energy generated by means of this oxidation is supplied to the catalyst, thereby providing a reduction of the light-off time of the catalyst.

Abstract: In a mobile telecommunications network, a mobile station (MS) is configured to generate and uplink transmit position measuring data prior to and/or during a call connection, without noticeably interrupting the user or degrading the quality of service provided. Position measuring data can be uplink transmitted over an idle traffic channel during a call set up operation for a brief moment while the call connection is being completed. Position measuring data can also be uplink transmitted during a call by selectively stealing data positions or burst positions in the uplink signal. The position measuring data is received by a plurality of base stations and uplink signal characteristics are measured and collected. The measured uplink signal characteristic data from several base stations is then used to determine a current approximate geographical location of the mobile station.
