Abstract

Oppfinnelsen beskriver en fremgangsmåte for overlevering mellom celler av en mobil stasjon i et sentralsystem, innbefattende: en basestasjon i en kildecelle sender en overleveringsanmodningsmelding til en basestasjon i en målcelle når den mobile stasjonen kommer inn i dekningsområdet til målcellen; basestasjonen i målcellen bestemmer om den selv har tildelt en forover rettet delt trafikkanal (S-TCH) til den ene eller de flere mobile stasjonene i en gruppe som den mobile stasjonen tilhører i målcellen, hvis basestasjonen i målcellen har tildelt en forover kanal S-TCH til den ene eller de flere mobile stasjonene i gruppen, aksesserer den mobile stasjonen forover kanalen S-TCH og avslutter prosessen; hvis basestasjonen i målcellen ikke har tildelt en forover kanal S-TCH til den ene eller de flere mobile stasjonene i gruppen, tildeler basestasjonen i målcellen en forover rettet dedikert trafikkanal (D-TCH) til den mobile stasjonen.The invention describes a method for transferring between cells of a mobile station in a central system, including: a base station in a source cell sends a handover request message to a base station in a target cell when the mobile station enters the coverage area of the target cell; the base station of the target cell determines whether it has assigned a forward-directed shared traffic channel (S-TCH) to one or more mobile stations in a group to which the mobile station belongs in the target cell, if the base station of the target cell has assigned a forward channel S-TCH to one or more mobile stations in the group, the mobile station accesses the channel S-TCH and terminates the process; if the base station of the target cell has not assigned a forward channel S-TCH to one or more mobile stations in the group, the base station of the target cell assigns a forward-directed dedicated traffic channel (D-TCH) to the mobile station.
