Patent ID: 8165587

Claim:
A method in a cellular radio communications network including a core network coupled to a radio access network (RAN) having multiple RAN nodes for communicating with mobile radio terminals, each of the multiple RAN nodes serving one or more cells, the method comprising: establishing that at least one cell associated with a first RAN node is in a restricted or reserved access state in which access to the one cell is restricted for at least some mobile radio terminals; sending, by the first RAN node, a message to a second RAN node to inform the second RAN node of that restricted access cell; determining that the restricted status of the one cell has changed; generating a global message not related to a specific mobile terminal that includes information that the restricted status of the one cell has changed; and sending, by the first RAN node, the global message to the second RAN node to inform the second RAN node of the change in the restricted status of the one cell.
