The invention relates to management of radio resources allocated to communication channels each associated with requested QoS parameters in a mobile communication network, consisting of the following if there is a lack of resources when accepting a new channel request:

Preemption method for management of radio resources in a mobile communication network

Uplink inter-cell interference is evaluated by allocating positions to mobiles in the cell of interest (C) and in interfering cells, computing a value for inter-cell interference for this position, re-positioning the mobiles, and re-computing the inter-cell interference value, until the calculated inter-cell interference converges on a stable value. At each iteration, the interfering mobiles are allocated a positional distribution within their respective cells which is an image of the distribution used for the mobiles in the cell of interest. Power control is performed only for mobiles in the studied cell, and the assigned distribution of power values is also allocated to the mobiles in the interfering cells. An inter-cell interference evaluation system () includes a mobile-communication-unit positioning module (), a path loss computation module (), a power control module () and an inter-cell interference computation module (), operating under the control of a controller ().
