Abstract
Apparatus and a method for ciphering messages in mobile telecommunications system user equipment are disclosed. The apparatus is arranged to receive ciphering configuration parameters in a Radio Resource Control (RRC) layer; forward ciphering configuration parameters to a Radio Link Control (RLC) or Medium Access Control (MAC) layer; and, in response to subsequent receipt of a message from the network, which message indicates that the user equipment device is to start ciphering, configuring the user equipment device to start ciphering using the ciphering configuration parameters in the RLC/MAC layer.
Claims14
A method for applying ciphering in a mobile telecommunications system, the system comprising a network of a plurality of cells and at least one user equipment device, the method comprising, in the user equipment:
- receiving ciphering configuration parameters in a Radio Resource Control (RRC) layer;
- forwarding ciphering configuration parameters to a Radio Link Control (RLC) layer;
- subsequently receiving a message from the network, which message indicates that the user equipment device is to start ciphering,
- in response to receiving the message from the network, configuring the user equipment device to start ciphering using the ciphering configuration parameters in the RLC layer.
A method for applying ciphering in a mobile telecommunications system, the system comprising a network of a plurality of cells and at least one user equipment device, the method comprising, in the user equipment:
- receiving ciphering configuration parameters in a Radio Resource Control (RRC) layer;
- forwarding ciphering configuration parameters to a Medium Access Control (MAC) layer;
- subsequently receiving a message from the network, which message indicates that the user equipment device is to start ciphering,
- in response to receiving the message from the network, configuring the user equipment device to start ciphering using the ciphering configuration parameters in the MAC layer.
A mobile telecommunications device for use in a mobile telecommunications system, the system comprising a network of a plurality of cells and at least one device, the device being arranged in use to:
- receive ciphering configuration parameters in a Radio Resource Control (RRC) layer;
- forward ciphering configuration parameters to a Radio Link Control (RLC) layer;
- in response to subsequent receipt of a message from the network, which message indicates that the user equipment device is to start ciphering, configuring the user equipment device to start ciphering using the ciphering configuration parameters in the RLC layer.
A mobile telecommunications device for use in a mobile telecommunications system, the system comprising a network of a plurality of cells and at least one device, the device being arranged in use to:
- receive ciphering configuration parameters in a Radio Resource Control (RRC) layer;
- forward ciphering configuration parameters to a Medium Access Control (MAC) layer;
- in response to subsequent receipt of a message from the network, which message indicates that the user equipment device is to start ciphering, configuring the user equipment device to start ciphering using the ciphering configuration parameters in the MAC layer.
A computer-readable medium carrying one or more sequences of instructions for applying ciphering in a mobile telecommunications system, the system comprising a network of a plurality of cells and at least one user equipment device, which instructions, when executed by one or more processors, cause the one or more processors to carry out the steps of:
- receiving ciphering configuration parameters in a Radio Resource Control (RRC) layer;
- forwarding ciphering configuration parameters to a Radio Link Control (RLC) layer;
- subsequently receiving a message from the network, which message indicates that the user equipment device is to start ciphering,
- in response to receiving the message from the network, configuring the user equipment device to start ciphering using the ciphering configuration parameters in the RLC layer.
