Abstract

Sammendrag Teknikker for effektiv utførelse av systemsøking for å hente ut tjeneste fra et trådløst system så raskt som mulig går ut på at en terminal først ser etter tjeneste fra et første system (feks. et system W-CDMA) og deretter identifiserer nett i dette system, fra hvilke tjeneste allerede var mottatt tidligere. Terminalen henter inn informasjon om hvert nett for å se for tjeneste fra dem. Finnes ingen slik tjeneste for det første system utføres et søk for et andre system (feks. GSM). Finnes tjeneste på det andre system får terminalen tjeneste fra dette og unngår en frekvensavsøking for det første system. Ellers utfører terminalen slik frekvensavsøking for det første system ved bruk av søkerresultatene for det andre system. Terminalen kan etablere en liste over høyfrekvenskanaler detektert for det andre system og kan unngå disse kanaler og eventuelt enkelte andre rundt dem, fra frekvensavsøkingen.
