Machine-to-machine (M2M) packet transmission of a machine device residing in a connected mode is conducted 310 using a bearer connection with a security context. After completion of the M2M packet transmission, the machine device transitions 320 from the connected mode to an intermediate mode, in which the machine device is neither in connected mode nor in idle mode, and preferably keeps the security context of the connection for the intermediate mode. After elapse of an inactivity period of the M2M packet transmission, the machine device transitions 330 from the intermediate mode to the connected mode and conducts M2M packet transmission by reactivating the bearer connection with the security context, for example by applying a radio network temporary identifier (C-RNTI) of the machine device that has been allocated before transition to the intermediate mode. |
