The present disclosure concerns radio communication. More particularly, the present disclosure inter alia introduces methods and means for improved radio access bearer (RAB) release, particularly in situations when there is a RAB limitation requirement. According to one embodiment, a method is performed by a radio network node. The radio network node is handling a set of RABs. This set of RABs consists of one or more RABs. Information related to each RAB of the set of RABs is obtained (130). The obtained information is processed (140) to generate a predicted timing of a next data transmission for each RAB. Also, a ranking is determined (150) for each RAB. This ranking is determined based on the predicted timing. Furthermore, a subset of the set of RABs is selected (160) based on the determined ranking. The subset of the set of RABs is selected (160) in such way that a cardinality of the selected subset complies with a RAB limitation requirement. Finally, any RAB of the set of RABs which is not in the selected subset is released (170), whereas any RAB of the set of RABs which is in the selected subset is kept (180). |
