A method of accessing a base station from a mobile station in a mobile radio system, in which the mobile station communicates with the base station in one or more time slots included in a frame according to the TDMA-principle. In one time slot, there are reserved fields for control information (SACCH, DVCC) which, however, are not used in the uplink and the downlink communication if the time slot represents a digital control channel. According to the invention, these fields are used by a mobile station (MS1) to transmit control information (R) to the base station (B1) which indicates the time slot order number and how many such time slots which are to be reserved by the base station in order that the mobile station should be able to complete its access message. The method is described both for the full rate mode and for the half rate mode. |
