Abstract
Abstract Telecommunications network decision making (such as call admission and call congestion control) utilizes as input, not only information in the cell where the call is setup, but also cell condition information from cells which neighbor the cell where the call is setup. The cell condition information from neighboring cells is obtained even in situations in which the neighboring cell is controlled by another exchange, e.g., another radio network controller (RNC). In an illustrated embodiment, the cell condition information utilized by the decision making includes measured data taken over at least a multi-connection portion of cell, one example of which is radio interference information. The cell condition information utilized in the network decision making is transmitted between exchanges (e.g., between radio network controllers [RNCs] using common channel signaling.
