Providing access control parameters to a user equipment

A computer storage device storing an executable computer program that, when executed by processor circuitry in a base station, causes the base station to perform a method, comprising:

• including an access control parameter in an access control message to be transmitted over a radio interface, the access control parameter being configured for allowing a radio device which receives it as part of an access procedure for accessing the radio communication system to determine whether access to said system is permitted;
• and
• sending the access control message on a channel which the radio device that intends to connect to the base station has to receive as part of its access procedure;
• the access control message also comprising a parameter for one of controlling and modifying the behaviour of the radio device, the parameter for the one of controlling and modifying the behaviour of the radio device being for modifying the behaviour of the radio device by changing the priority of one of the current cell and radio carrier if the access control parameter indicates that the radio device is not permitted access;
• the access control message is one of sent and indicated on a Physical Downlink Control Channel, PDCCH;
• and
• the access control message is one of:
• a Downlink Control Information, DCI, format;
• and
• associated with a particular Radio Network Temporary Identity, RNTI.

A base station for a radio communication system, the base station comprising:

• processor circuitry;
• and
• a storage unit storing instructions that, when executed by the processor circuitry, cause the base station to:
• include an access control parameter in an access control message to be transmitted over a radio interface, the access control parameter being configured for allowing a radio device which receives the access control parameter as part of an access procedure for accessing the radio communication system to determine whether access to said system is permitted;
• and
• send the access control message on a channel which a radio device that intends to connect to the base station has to receive as part of the radio device's access procedure;
• the access control message also comprising a parameter for one of controlling and modifying the behaviour of the radio device, the parameter for the one of controlling and modifying the behaviour of the radio device being for modifying the behaviour of the radio device by changing the priority of one of the current cell and radio carrier if the access control parameter indicates that the radio device is not permitted access;

A method performed in a radio device associated with a radio communication system, the method comprising:

• receiving an access control message comprising an access control parameter from a base station in the radio communication system, the access control message being one of received on a Physical Downlink Control Channel, PDCCH, and indicated on the PDCCH, as part of an access procedure for accessing said system;
• determining, based on the received access control parameter, whether access to the system is permitted;
• the access control message also comprising a parameter for one of controlling and modifying the behaviour of the radio device, the parameter for the one of controlling and modifying the behaviour of the radio device being for modifying the behaviour of the radio device by changing the priority of one of the current cell and radio carrier if the access control parameter indicates that the radio device is not permitted access;
• and
• the access control message is one of:
• a Downlink Control Information, DCI, format;
• and
• associated with a particular Radio Network Temporary Identity, RNTI.
