    摘要： A cellular radio communications network includes a core network with a core network node coupled to a radio access network (RAN) associated with a first radio access technology for communicating with mobile radio terminals. The RAN includes multiple RAN nodes. Each mobile radio terminal has an associated access class for accessing service from the cellular radio communications network. The core network node detects an overload condition and sends an overload message to the RAN nodes that includes information for reducing the overload condition. Each of the RAN nodes receives the overload message and determines whether an access class restriction should be implemented to reduce the number of mobile radio terminals permitted to access the cellular radio communications network. If so, the RAN node determines one or more access classes of mobile radio terminals to be restricted based on the information in the overload message. Information relating to the one or more restricted access classes is transmitted in an area associated with the RAN node so that the mobile terminals of a restricted access class are prohibited from accessing the cellular radio communications network.

    摘要： A cellular radio communications network includes a core network coupled to a radio access network (RAN) that has multiple RAN nodes for communication with mobile radio terminals. Each of the multiple RAN nodes serves one or more cells. 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. The first RAN node sends a message to a second RAN node to inform the second RAN node of that restricted access cell. The fact that the restricted status of the one cell has changed is detected. A global message tha is not related to a specific mobile terminal is generated that includes information that the restricted status of the one cell has changed. The first RAN node sends 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.
