Patent ID: 7339950

Claim:
A method for allocating radio resources to a plurality of radio bearers in a wireless communications network, said method comprising: determining for each radio bearer or for each set of radio bearers of at least a selected group of said radio bearers or of sets of said radio bearers the current activity status; determining a value indicative of a probability of outage based on a probability with which each radio bearer or each set of radio bearers will change its current activity status; wherein as said value indicative of the probability of outage a probability is determined with which one of the total power of received or transmitted signals respectively of all radio bearers in said wireless communications network will exceed a predetermined power level threshold value or the total throughput of transmitted or received signals respectively of all radio bearers in said wireless communications network will exceed a predetermined throughput threshold value, when taking into account the probability with which each radio bearer or set of radio bearers of said group of radio bearers or sets of radio bearers will change its current activity status within a predetermined period of time; and deciding based on a comparison of said determined value indicative of the probability of outage with a predetermined threshold value whether the current allocation of radio resources is to be changed.
