Abstract: Methods and devices for determining a geographic location of an electronic device are introduced. A range of radio frequencies at the electronic device's location is scanned by a radio receiver ( 11 ). Characteristics (CH) of a geographically bound transmission system ( 3 ) within said scanned frequencies are identified by a control unit ( 21 ). A matching unit ( 5 ) matches these characteristics (CH) with stored characteristics (SCH) of geographically bound transmission systems of different geographical areas. The geographic location (LD) of said electronic device ( 1 ) is dependent on a result of said matching process.

Abstract: PCT No. PCT/EP93/00677 Sec. 371 Date Aug. 9, 1995 Sec. 102(e) Date Aug. 9, 1995 PCT Filed Mar. 20, 1993 PCT Pub. No. WO94/22253 PCT Pub. Date Sep. 29, 1994The present application concerns a method and an apparatus, in a communication network, for processing the various fields of a protocol header preceding a data stream to provide a unique connection identifier for processing the data stream. All relevant protocol information is extracted from the protocol header for look up in a Content-Addressable Memory (CAM) (80). Each time an entry in the CAM (80) matches protocol information applied to the CAM's input (84), the CAM address of this storage section, i.e. the address of a row of the CAM (80), is provided at the output (82) thereof. The CAM addresses obtained from the protocol header are concatenated by means of a Connection Number Builder (CNB, 95) resulting in a unique connection identifier provided at the Protocol Filter's output (96) to be used for the processing of the data stream.
