Abstract
A packet data service node (PDSN) is formed to establish a connection with a plurality of mobile terminals by way of one or more packet control function cards or devices. A packet control function (PCF) card or device is formed to provide an interface between the packet data domain and wireless domain and further to inform a base station controller/access network controller (BSC/ANC) to block the setup and establishment of any additional communication links in a specified manner until the overload condition ceases to exist. More specifically, the PCF receives loading information from each PDSN to which it is connected and determines a composite loading factor. The PCF transmits the composite loading factor to the BSC/ANC periodically or if the loading factor exceeds a specified threshold and call blocking should be initiated for packet data calls for a select group of mobile terminals.
