A method of allocating radio resource by preemption in the event of an inter-cell transfer in a cellular radio system for communication with mobiles, the request being for transfer from a "server" cell under the control of a "server" entity of the system to a "target" cell selected from a set of "candidate" cells under the control of a "target" entity of the system, the server and target entities themselves being under the control of a "higher level" entity of the system, wherein the server entity, after it has informed itself that no radio resource is available in any one of the candidate cells, sends to the higher level entity a request to implement the preemption procedure, and wherein the higher level entity then sends to the target entity confirmation of said request to implement the preemption procedure.
