Access to a cellular network for machine type communication devices
First Claim
1. A method of controlling access by a User Equipment (UE) to a cellular network, comprising:
- receiving an instruction at the UE from a base station of the cellular network to make a transmission from the UE over a Random Access Channel (RACH) of the cellular network; and
making a transmission from the UE over the RACH in response to the received instruction, if the UE has data to send over the cellular network, in order to send this data.

Abstract
Controlling access by a User Equipment (UE) to a cellular network may be effected by: receiving an instruction at the UE from a base station of the cellular network regarding transmission by the UE over a Random Access Channel (RACH) of the cellular network; and controlling when transmissions are made from the UE over the RACH, on the basis of the received instruction. In some cases, a transmission over the RACH may be made in response to the received instruction, which gives permission for the UE to transmit if it has data to send. In other cases, the instruction specifies a Group Identifier, which is compared with a Group Identifier specific to the UE and transmission over the RACH may be avoided based on the comparison. In particular, the UE may be a Machine Type Communication device.

11. A method of controlling access by a User Equipment (UE) to a cellular network, the UE having an associated Group Identifier distinct from an Access Class associated with the UE, the method comprising:
-
receiving an instruction at the UE from a base station of the cellular network to make a transmission from the UE over a Random Access Channel (RACH) of the cellular network, the instruction further specifying a Group Identifier; comparing, at the UE, the Group Identifier specified by the instruction with the Group Identifier associated with the UE; and avoiding making a transmission from the UE over the RACH for a period of time based on the result of the step comparing. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A User Equipment (UE) for a cellular network, the UE having an associated Group Identifier that is distinct from an Access Class associated with the UE, the UE comprising:
a processor configured to receive an instruction from a base station of the cellular network, the instruction specifying a Group Identifier, and further configured to compare the specified Group Identifier and the Group Identifier associated with the UE and to control the UE to avoid transmissions over a Random Access Channel (RACH) of the cellular network for a period of time based on the comparison.

19. A User Equipment (UE) for a cellular network, comprising:
-
a receiver, arranged to receive an instruction from a base station of the cellular network to make a transmission over a Random Access Channel (RACH) of the cellular network; a transmitter for transmitting over the RACH; and a processor, configured to control the transmitter to transmit over the RACH in response to the received instruction, if the UE device has data to send over the cellular network, in order to send this data.

20. A non-transitory computer readable medium storing software for controlling access by a User Equipment (UE) to a cellular network, the software comprising:
-
executable code that receives an instruction at the UE from a base station of the cellular network to make a transmission from the UE over a Random Access Channel (RACH) of the cellular network; and executable code that makes a transmission from the UE over the RACH in response to the received instruction, if the UE has data to send over the cellular network, in order to send this data.

21. A non-transitory computer readable medium storing software for controlling access by a User Equipment (UE) to a cellular network, the UE having an associated Group Identifier distinct from an Access Class associated with the UE, the software comprising:
-
executable code that receives an instruction at the UE from a base station of the cellular network to make a transmission from the UE over a Random Access Channel (RACH) of the cellular network, the instruction further specifying a Group Identifier; executable code that compares, at the UE, the Group Identifier specified by the instruction with the Group Identifier associated with the UE; and executable code that avoids making a transmission from the UE over the RACH for a period of time based on a result from the executable code that receives the instruction.
