"The process to increase capacity in a cellular communications system and controller that coordinates the establishment of a traffic channel of first rate for a communication with a mobile stationIt is served by a base station in a cellular communications system.The present invention dynamically increases the capacity of a system of cellular radio communications to satisfy high demands of temporary traffic efficiently and economically.The traffic load current in an area of the cell of the base station specific is determined (14).If the traffic load determined exceeds a threshold value (16).A traffic channel of the highest rate whereby a mobile station of the dual rate is communicating is transferred to a traffic channel of the lowest rate available in the area of cell DIsponu00edvel in that area of the cell (18). A list is maintained for those mobile stations double rate currently allocated to traffic channels of higher rate.Prior to the transfer of the traffic channel of the highest rate for the traffic channel of the lowest rate, it is determined whether a transfer is permitted.If so, the transfer of intra cell preferably is made for a traffic channel which is currently supporting another call to the lowest rate.In the negative, any traffic channel of the lowest rate available is allocated: in the establishment of the call, if the traffic load current in the area of the cell exceeds the threshold value.A request for a call involving a mobile station of the dual rate is allocated to a traffic channel to the lower rate (20).If the traffic load in the cell area decreases.A call originally established or subsequ00b3entemente transferred to a channel of the lowest rate due to a high load of traffic can optionally be transferred to a channel rate most alt(17).
