METHOD FOR CONTROLLING RADIO RESOURCES ASSOCIATED WITH A MOBILE STATION, AND RADIO COMMUNICATION SYSTEM

摘要

The invention relates to a method for controlling radio resources associated with a mobile station, whereby the mobile station is switched to different operating states, the mobile station is switched to a dedicated data state (CELL_DCH) in which radio resources dedicated to the mobile station are assigned to the transmission of signalling data and useful data, the mobile station is switched to a common radio call signalling state (CELL_PCH or URA_PCH) in which the radio resources common to the mobile station are assigned to the transmission of signalling data, and the mobile station is switched, without intermediate switching of another operating state, from a common radio call signalling state (CELL_PCH or URA_PCH) to the dedicated data state (CELL_DCH).
