1. A method for preventing congestion at radio access in a cellular mobile communication system, said method comprising:
- receiving information broadcast from a radio access network entity at a Mobile Terminal in a cellular mobile communication network, the information indicating a currently allowed range of different ranges into which Machine-to-Machine (M2M) Mobile Terminals operating in the cellular mobile communication network are split, wherein the radio access network entity changes the currently allowed range of the different ranges upon time,calculating a member range of the different ranges to which the Mobile Terminal belongs by performing a modulo operation, the member range corresponding to a remainder after division of an identifying number associated with the Mobile Terminal by a modulo number associated with the modulo operation, the identifying number associated with the Mobile Terminal being such that corresponding numbers associated with the M2M Mobile Terminals are evenly distributed among the M2M Mobile Terminals,checking whether the member range for the Mobile Terminal is the currently allowed range,refraining from initiating radio access to the cellular mobile communication network via the radio access network entity if the Mobile Terminal is an M2M Mobile Terminal and the member range for the Mobile Terminal is not the currently allowed range, andin case of messages defined as urgent, the Mobile Terminal carrying out radio access despite the member range for the Mobile Terminal not being the currently avowed range.

8. A Mobile Terminal, comprising:
-
at least one processor; and a transceiver; wherein the at least one processor and the transceiver are configured to receive information broadcast from a radio access network entity in a cellular mobile communication network, the information indicating a currently allowed range of different ranges into which Machine-to-Machine (M2M) Mobile Terminals operating in the cellular mobile communication network are split, wherein the radio access network entity changes the currently allowed range of the different ranges upon time; wherein the at least one processor and the transceiver are configured to calculate a member range of the different ranges to which the Mobile Terminal belongs by performing a modulo operation, the member range corresponding to a remainder after division of an identifying number associated with the Mobile Terminal by a modulo number associated with the modulo operation, the identifying number associated with the Mobile Terminal being such that corresponding numbers associated with the M2M Mobile Terminals are evenly distributed among the M2M Mobile Terminals, wherein the at least one processor and the transceiver are configured to check whether the member range for the Mobile Terminal is the currently allowed range; wherein the at least one processor and the transceiver are configured to refrain from initiating radio access to said cellular mobile communication network via the radio access network entity if the Mobile Terminal is an M2M Mobile Terminal and the member range for the Mobile Terminal is not the currently allowed range, and wherein the at least one processor and the transceiver, in case of messages defined as urgent, are configured to carry out radio access despite the member range for the Mobile Terminal not being the currently allowed range. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method for preventing congestion at radio access in a cellular mobile communication system, said method comprising:
-
broadcasting information from a radio access network entity operating in a cellular mobile communication network for reception by compatible Mobile Terminals within communication of the radio access network entity;
the information indicating a currently allowed range of different ranges into which Machine-to-Machine (M2M) Mobile Terminals operating in the cellular mobile communication network are split; andchanging the currently allowed range of the different ranges upon time; wherein the information includes a modulo number that enables a Mobile Terminal receiving the broadcasted information to calculate a member range of the different ranges to which the Mobile Terminal belongs by performing a modulo operation, the member range corresponding to a remainder after division of an identifying number associated with the Mobile Terminal by the modulo number associated with the modulo operation, wherein the calculated member range enables the Mobile Terminal to check if it belongs to the currently allowed range; wherein the Mobile Terminal is configured to refrain from initiating radio access to the cellular mobile communication network via the radio access network entity if the Mobile Terminal is an M2M Mobile Terminal and the member range for the Mobile Terminal is not the currently allowed range, wherein in case of messages defined as urgent, the Mobile Terminal is configured to carry out radio access despite the member range for the Mobile Terminal not being the currently allowed range. - View Dependent Claims (16, 17, 18)

19. A radio access network entity, comprising:
-
at least one processor; and a transceiver; wherein the at least one processor, and the transceiver are configured to broadcast information in a cellular mobile communication network for reception by compatible Mobile Terminals, the information indicating a currently allowed range of different ranges into which Machine-to-Machine (M2M) Mobile Terminals operating in the cellular mobile communication network are split; wherein the at least one processor and the transceiver are configured to change the currently allowed range of the different ranges upon time; wherein the information includes a modulo number that enables a Mobile Terminal receiving the broadcasted information to calculate a member range of the different ranges to which the Mobile Terminal belongs by performing a modulo operation, the member range corresponding to a remainder after division of an identifying number associated with the Mobile Terminal by the modulo number associated with the modulo operation, wherein the calculated member range enables the Mobile Terminal to check if it belongs to the currently allowed range; wherein the Mobile Terminal is configured to refrain from radio access to the cellular mobile communication network via the radio access network entity if the Mobile Terminal is an M2M Mobile Terminal and the member range for the Mobile Terminal is not the currently allowed range, wherein in case of messages defined as urgent, the Mobile Terminal is configured to carry out radio access despite the member range for the Mobile Terminal not being the currently allowed range. - View Dependent Claims (20, 21, 22)
