Abstract
The network resources allocated to Machine Type Communication (MTD) devices (also referred to as Machine-to-Machine (M2M) Devices) can be reduced through the introduction of a new device state in a network. The network device state, referred to as a sleep state, allows the network to offload context information about the device to another network element so that the resources allocated to the sleeping device can be released. When the device needs to be contacted by a network element, the stored context information can be retrieved to facilitate paging the otherwise offline device.

9. A node for storing context information about user equipment connected to a radio access network, the node comprising:
-
a primary storage for storing context information associated with user equipment; a radio interface for receiving requests transmitted over a radio access network from user equipment; a network interface for communicating with external nodes; and a processor for receiving, from a user equipment over the radio interface, an indication that the user equipment is entering a low traffic state, for transmitting to a secondary storage context information associated with the user equipment stored in the primary storage, for deleting at least part of the context information transmitted to the secondary storage from the primary storage, and for transmitting a request to at least one external node over the network interface to release resources allocated to the user equipment in response to the receipt of the indication.
