    摘要： An apparatus (201) comprises means for:
    obtaining an indication of contention (105) of a communications network (101);
    obtaining a historical bandwidth utilization indication parameter (302) of respective participants of the communications network (101) ;
    in response to determining, based on the indication of contention and the historical bandwidth utilization indication, that a participant meets an intensive capacity consumption condition, providing a reduced value of a scheduler parameter (304) and an increased value of a maximum bandwidth parameter (303) to an output of the apparatus (201), wherein the scheduler parameter and the maximum bandwidth parameter are related to allocating bandwidth to the participant meeting the intensive capacity consumption condition, wherein the scheduler parameter represents a proportion of a capacity of the communications network allocated to the participant when the communications network is congested, wherein the maximum bandwidth parameter represents a maximum bandwidth allocated to the participant.
