Abstract text


The present invention relates to a node and a method in a cellular radio network telecommunication system for assigning resources to users, comprising a network node having resources to be allocated to users being present in a radio cell served by the network node. The invention comprises:—assigning a priority to each user in the radio cell, where a user consuming a larger portion of the resources is assigned a lower priority than a user consuming a lower portion of the resources,—receiving a rate request, requesting a larger transmission rate, from a first user having a first priority. If not sufficient free resources are available to fulfil said first users rate request, the following steps are performed:—selecting a second user having lower priority than said first user,—sending messages to said first and second users indication the scheduled grant, and—transferring resources, assigned to said second user, from said second user to said first user, to thereby decrease the consumed resources for said second user and increase the consumed resources for said first user.
