Abstract:
1. A method of allocating radio resources to an elastic session, where a rate by which bits are transmitted can vary during an ongoing session, transmitted over a radio interface between a radio base station involved in a plurality of other ongoing sessions and a mobile station in a mobile radio network operating according to code division multiple access, the method comprising the steps of: allocating, to the elastic session, a radio resource share corresponding to a reduced transmission rate where the reduction in transmission rate corresponds to a peak transmission rate of the elastic session, which is the maximum transmission rate at which the elastic session can operate, being slowed down by a first slowdown rate; determining the first slow down rate in dependency of the transmission rate requirements of the ongoing sessions in a manner so that the radio resource share allocated is not lower than a radio resource share corresponding to the maximum transmission rate if a total amount of resources available for the radio base station to allocate to ongoing sessions is sufficient for all ongoing sessions to transmit at a respective peak transmission rate; the elastic session belongs to one of at least two session classes; the first slow down rate is determined in accordance with a priority policy according to which different session classes are given different priority and sessions of a higher priority class are allocated radio resources corresponding to a reduced transmission rate only if a reduction of transmission rate of sessions of session classes of lower priority is not sufficient; and each ongoing session is associated with a peak transmission rate; and the allocating of resources to the elastic session is performed upon an indication indicating that a total amount of resources available for allocating to ongoing sessions is not sufficient for all ongoing sessions to operate at their respective peak transmission rate.
