A method for controlling transmission of machine type communication data to or from machine type communication devices within a mobile communication system, the method comprising the following steps performed by a network node in the radio access network or in the core network of the mobile communication system: receiving a first connection request message in the control plane from a mobile terminal, wherein the first connection request message requests the establishment of a connection between the network node and the mobile terminal, and indicates that the requesting mobile terminal is a machine type communication device; determining one or more timeslots for transmitting the machine type communication data, wherein the determined one or more timeslots are timeslots for which a maximum load count has not been reached and the determination is based on load information that indicate the estimated load of the mobile communication system at different future timeslots including said one or more determined timeslots; transmitting, in the control plane and to the mobile terminal, a first connection setup message, wherein the first connection setup message informs the mobile terminal on the one or more determined timeslots for transmitting the machine type communication data; and either comprising: receiving, in response to the first connection setup message and in the control plane, a connection setup complete message from the mobile terminal accepting one of the one or more determined timeslots; and increasing the load count for the accepted one timeslot, in response to receiving the connection setup complete message; or comprising: increasing the load count for the one or more determined timeslots, receiving, in response to the first connection setup message and in the control plane, a connection setup complete message from the mobile terminal accepting one of the one or more determined timeslots; and decreasing the load count for the non-accepted one or more determined timeslots, in response to receiving the connection setup complete message. receiving a first connection request message in the control plane from a mobile terminal, wherein the first connection request message requests the establishment of a connection between the network node and the mobile terminal, and indicates that the requesting mobile terminal is a machine type communication device; determining one or more timeslots for transmitting the machine type communication data, wherein the determined one or more timeslots are timeslots for which a maximum load count has not been reached and the determination is based on load information that indicate the estimated load of the mobile communication system at different future timeslots including said one or more determined timeslots; transmitting, in the control plane and to the mobile terminal, a first connection setup message, wherein the first connection setup message informs the mobile terminal on the one or more determined timeslots for transmitting the machine type communication data; and either comprising: receiving, in response to the first connection setup message and in the control plane, a connection setup complete message from the mobile terminal accepting one of the one or more determined timeslots; and increasing the load count for the accepted one timeslot, in response to receiving the connection setup complete message; receiving, in response to the first connection setup message and in the control plane, a connection setup complete message from the mobile terminal accepting one of the one or more determined timeslots; and increasing the load count for the accepted one timeslot, in response to receiving the connection setup complete message; or comprising: increasing the load count for the one or more determined timeslots, receiving, in response to the first connection setup message and in the control plane, a connection setup complete message from the mobile terminal accepting one of the one or more determined timeslots; and decreasing the load count for the non-accepted one or more determined timeslots, in response to receiving the connection setup complete message. increasing the load count for the one or more determined timeslots, receiving, in response to the first connection setup message and in the control plane, a connection setup complete message from the mobile terminal accepting one of the one or more determined timeslots; and decreasing the load count for the non-accepted one or more determined timeslots, in response to receiving the connection setup complete message.
