Claims (3)
1. Radiokommunikationssystem, der indbefatter en basisstationsenhed (10) og en mobilstationsenhed (50), hvor basisstationsenheden (10) er indrettet til at overføre synkron tidsafvigelsesinformation til en mobilstationsenhed (50), hvor mobilstationsenheden (50) er indrettet at administrere en synkron uplink status ved anvendelse af en timer, således at den synkrone uplink status opretholdes, indtil timeren udløber, efter timeren nulstilles ved modtagelsen af den synkrone tidsafvigelsesinformation, der er overført og beregnet baseret på modtagelse af timing af en direkte tilgang, der er indledt af basisstationsenheden (10), hvor mobilstationsenheden (50) er indrettet til: at overføre en indledende direkte tilgang (SOI) til basisstationsenheden (10); at modtage, fra basisstationsenheden (10), et direkte tilgangs-svar (S02), der svarer til den indledende direkte tilgang (SOI), hvis indledende ID blev tilfældigt udvalgt af mobilstationsenheden (50) og overført til basisstationsenheden (10) ; at udføre uplink tidstilpasning baseret på den synkrone tidsafvigelsesinformation, i tilfælde af at, i en asynkron uplink status, den synkrone tidsafvigelsesinformation er indbefattet i det direkte tilgangs-svar (S02); kendetegnet ved, at mobilstationsenheden (50) er indrettet til, i en synkron uplink status, ikke at udføre uplink tidstilpasning, der er baseret på tidsafvigelsesinformation, som er indbefattet i det direkte tilgangs-svar (S02), og svarer til den indledende direkte tilgang (SOI), hvis indledende ID blev tilfældigt udvalgt af mobilstationsenheden (50) og overført til basisstationsenheden (10).
2. Mobilstationsenhed (50), der er indrettet til at administrere en synkron uplink status ved anvendelse af en timer, således at den synkrone uplink status opretholdes, indtil timeren udløber, efter timeren nulstilles ved modtagelsen af synkron tidsafvigelsesinformation, der er overført og beregnet baseret på modtagelse af timing af en direkte tilgang, der er indledt af en basisstationsenhed (10), hvor mobilstationsenheden (50) er indrettet til: at overføre en indledende direkte tilgang (SOI) til basisstationsenheden (10); at modtage, fra basisstationsenheden (10), et direkte tilgangs-svar (S02), der svarer til den indledende direkte tilgang (SOI), hvis indledende ID blev tilfældigt udvalgt af mobilstationsenheden (50) og overført til basisstationsenheden (10) ; at udføre uplink tidstilpasning baseret på den synkrone tidsafvigelsesinformation, i tilfælde af at, i en asynkron uplink status, den synkrone tidsafvigelsesinformation er indbefattet i det direkte tilgangs-svar (S02); kendetegnet ved, at mobilstationsenheden (50) er indrettet til, i en synkron uplink status, ikke at udføre uplink tidstilpasning baseret på tidsafvigelsesinformation, der er indbefattet i det direkte tilgangs-svar (S02), og svarer til den indledende direkte tilgang (SOI), hvis indledende ID blev tilfældigt udvalgt af mobilstationsenheden (50) og overført til basisstationsenheden (10).
3. Forarbejdningsmetode, der udføres af en mobilstationsenhed (50), der administrerer en synkron uplink status ved anvendelse af en timer, således at den synkrone uplink status opretholdes, indtil timeren udløber, efter timeren nulstilles ved modtagelsen af synkron tidsafvigelsesinformation, der er overført og beregnet baseret på modtagelse af timing af en direkte tilgang, der er indledt af en basisstationsenhed (10); hvor forarbejdningsmetoden omfatter: overførsel af en indledende direkte tilgang (SOI) til basisstationsenheden (10); modtagelse af, fra basisstationsenheden (10), et direkte tilgangs-svar (S02), der svarer til den indledende direkte tilgang (SOI), hvis indledende ID blev tilfældigt udvalgt af mobilstationsenheden (50), og overført til basisstationsenheden (10); udførelse af uplink tidstilpasning baseret på den synkrone tidsafvigelsesinformation, i tilfælde af at, i en asynkron uplink status, den synkrone tidsafvigelsesinformation er indbefattet i det direkte tilgangs-svar (S02); og kendetegnet ved, at mobilstationsenheden (50), i en synkron uplink status, ikke udfører uplink tidstilpasning baseret på tidsafvigelsesinformation, der er indbefattet i det direkte tilgangs-svar (S02), og svarer til den indledende direkte tilgang (SOI), hvis indledende ID blev tilfældigt udvalgt af mobilstationsenheden (50) og overført til basisstationsenheden (10) .
