<p>A method for managing the transmit power of a broadcast channel transmitted by a radio access point in a cellular radiocommunication network comprising user terminals adapted for receiving data transmitted by radio access points over broadcast and/or unicast channels, said method comprising, with respect to user terminals receiving data broadcast by the radio access point in an established broadcast session over the broadcast channel:
- decreasing the transmit power of the broadcast channel by first predetermined amount;
- determining over a predetermined time interval a plurality of estimates of the density of user terminals located within the cell and outside said geographical area, which user terminals receive the broadcast session through at least one unicast channel; and
- increasing the transmit power of the broadcast channel by a predetermined amount if the values of estimates of the density tend to increase over time.</p> |
