Abstract

En fremgangsmåte og system for å utføre initial cellesøking i ttådløse kommunikasjonssystemer hvor uhensiktsmessige celler er ekskludert blir beskrevet. Lagrede frekvenser blir søkt uttømmende og initiale frekvenser er søkt ikke uttømmende. Initiale frekvenser kan bh søkt uttømmende under visse omstendigheter. Når det utføres uttømmende initiale cellesøkinger, vil primære synkroniseringskoder som leder til uhensiktsmessige celler bli ekskludert fra etterfølgende initiale cellesøkinger utført på den samme frekvensen.
