Advanced Machine-To-Machine Communications
First Claim
1. A method comprisingconducting machine-to-machine packet transmission of a machine device residing in a connected mode by using a bearer connection with a security context,causing transition of the machine device from the connected mode to an intermediate mode, in which the machine device is neither in connected mode nor in idle mode, after completion of the machine-to-machine packet transmission, and keeping the security context of the connection for the intermediate mode, andcausing transition of the machine device from the intermediate mode to the connected mode after elapse of an inactivity period of the machine-to-machine packet transmission, and conducting machine-to-machine packet transmission of the machine device residing in the connected mode by reactivating the bearer connection with the kept security context.

Abstract
There are provided measures for advanced machine-to-machine communications. Such measures may exemplarily includes conducting machine-to-machine packet transmission of a machine device residing in a connected mode by using a bearer connection with a security context, causing transition of the machine device from the connected mode to an intermediate mode, in which the machine device is neither in connected mode nor in idle mode, after completion of the machine-to-machine packet transmission, and keeping the security context of the connection for the intermediate mode, and causing transition of the machine device from the intermediate mode to the connected mode after elapse of an inactivity period of the machine-to-machine packet transmission, and conducting machine-to-machine packet transmission of the machine device residing in the connected mode by reactivating the bearer connection with the kept security context.

8. A method comprising
performing machine-to-machine packet transmission in a connected mode by using a bearer connection with a security context, transiting from the connected mode to an intermediate mode, which is neither connected mode nor idle mode, after completion of the machine-to-machine packet transmission, and transiting from the intermediate mode to the connected mode after elapse of an inactivity period of the machine-to-machine packet transmission, and performing machine-to-machine packet transmission in the connected mode on the reactivated bearer connection with the security context of the connection before transition to the intermediate mode.
