Benefits of technology

[0023]Desirably, the MTC device has an associated Home Public Land Mobile Network, HPLMN. Optionally, the method further comprises: receiving an instruction at the MTC device from the cellular radio network not to make a transmission from the MTC device for accessing the cellular network, the instruction specifying a criteria for the MTC device's HPLMN or preferred list of cellular networks; comparing, at the MTC Device, the criteria specified by the instruction with the HPLMN associated with the MTC device; and avoiding making further transmissions from the MTC device to access the cellular radio network for a period of time based on the result of the step of comparing. This enhanced Access Class Barring scheme improves the ability of a network, preferably the VPLMN to provide large numbers of random access channel transmissions from MTC

Example

[0032]Referring first to FIG. 1, there is shown a schematic diagram detailing an example configuration of MTC devices in a cellular network. There is provided: a Radio Access Network (RAN) 1; a first MTC device 100; a second MTC device 200; and a core network 40.

[0033]The RAN 1 may be GSM Base Station System (BSS), a UMTS Node B plus Radio Network Controller (RNC), an LTE eNode B or any other cellular network base station device. The base station 1 comprises: a transmitter 10; a receiver 20; and a processor 30. Similarly, the first MTC device 100 is a UE comprising a transmitter 110; a receiver 120; and a processor 130 and the second MTC device 200 is a UE comprising a transmitter 210; a receiver 220; and a processor 130. The processor 30 of the RAN 1 is linked to the core network 40. It will be understood that the RAN 1, first MTC device 100 and second MTC device 200 also comprise other hardware, software or both in order to carry out their functions.

Abstract

The invention relates to operating a Machine-Type Communication (MTC) device for communication with a cellular radio network. A transmission is made from the MTC device to the cellular radio network to register the MTC device with the cellular radio network. The transmission includes a message from the MTC device to the cellular radio network, identifying the MTC device as an MTC device to the cellular radio network. Also, the MTC device has an associated HPLMN. An instruction is received at the MTC device from the network not to make a transmission from the MTC device for accessing the network. The instruction specifies a criteria for the MTC device's HPLMN or preferred list of networks. The MTC Device compares the criteria with the HPLMN associated with the MTC device and avoids making a transmission to access the network for a period of time based on the result comparing step.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention concerns a method of operating a Machine-Type Communication (MTC) device for communication with a cellular radio network, a method of controlling access by an MTC device to a cellular radio network ,an associated MTC device and a method of operating a cellular radio network.BACKGROUND TO THE INVENTION[0002]Machine Type Communication (MTC) devices (sometimes referred to as Machine-to-Machine or M2M devices) are increasingly being used for a variety of applications. Their numbers are expected to grow at a high rate. MTC devices are typically automated data reporting systems such as utility meters or status reporting devices.[0003]Thus, MTC devices are likely to have significantly different usage or operational characteristics from other types of User Equipment, UE. Such devices may be programmed to send data at a specific time, for example late at night. Also, other types of MTC devices may be triggered by specific events, su...
