Abstract

Omruting mellom to kommunikasjonsnett med basestasjoner (4), reléstasjoner (8) og mobile radiostasjoner (6), blant annet for CDMA eller annen teknologi og ved forskjellig frekvens. En første basesta-sjon (4) dekker to eller flere sektorer, og en av disse er tilordnet en reléstasjon (8) som gir dekningsoverlapping for begge nett. Når en forflyttbar stasjon (6) kommer inn i dekningsområdet for reléstasjonen (8) identifiseres dennes pilotsignal, dets feltstyrke måles og resultatet sendes til det første nett. Er signalstyrken over en gitt tilføyelsesterskel føyes reléstasjonen (8) til en liste over aktive stasjoner hos den forflyttbare stasjon.Det første nett kan sørge for omruting av kommunikasjonen til/fra denne stasjon (6) til det andre nett, på blant annet fem måter: 1) ved å la basestasjonen (4) i det første nett sette i gang omrutingen, 2) dersom reléstasjonens (8) pilotsignalstyrke, målt i stasjonen (6), overstiger en gitt omrutingsterskel, 3) dersom basestasjonen (4) i det første nett tas ut fra settet aktive stasjoner hos stasjonen (6), 4) dersom reléstasjonen (8) i det første nett tas ut fra samme sett med aktive stasjoner, eller 5) dersom basestasjonen (4) og reléstasjonen (8) i det første nett begge tas ut fra dette sett.Routing between two communication networks with base stations (4), relay stations (8) and mobile radio stations (6), including for CDMA or other technology and at different frequencies. A first base station (4) covers two or more sectors, and one of these is assigned a relay station (8) which provides coverage overlap for both networks. When a mobile station (6) enters the coverage area of the relay station (8), its pilot signal is identified, its field strength is measured and the result is sent to the first network. If the signal strength is above a given addition threshold, the relay station (8) is added to a list of active stations at the mobile station. The first network can provide routing of the communication to / from this station (6) to the second network, in five ways: 1) by allowing the base station (4) in the first network to start the rerouting, 2) if the pilot signal strength of the relay station (8), measured in the station (6), exceeds a given rerouting threshold, 3) if the base station (4) in the first network is taken from the set of active stations at the station (6), 4) if the relay station (8) in the first network is taken from the same set of active stations, or 5) if the base station (4) and the relay station (8) in the first network are both taken from this set.
