Allocation of radio resources to radio bearers

The invention relates to distributed radio resource to the radio carriers in wireless communication networks method, module and algorithm. In turn to improve the distribution of assigned claims, the first by at least one group selecting the radio holding multiple and/or between the radio carrier each radio carrier and/or each radio carrier fixing device is current of active (21 and 22). , Then according to the selecting each radio carriers and/or the middle one group of radio support column wherein the working state (21 and 22) and probability (p and q), determining unit of the engine of probability value. Finally, according to determining expression engine probability of the comparison of value and preset threshold value, determining whether flowing change the current distribution of radio resource. The invention also relates to a corresponding component wireless access network.
