Abstract
A method for radio resources management within a set of cells (C1, . . . , CN) covered by base stations (BS1, . . . , BSN), comprising:—retrieving traffic demands information including relative Quality of Service (QoS) and radio performance figures on each cell (Ci) from correspondent base station (BSi);—processing the traffic demands information so as to detect at least one periodic traffic pattern;—adjusting allocated radio resources for each cell (Ci) according to the detected at least one periodic traffic pattern; and—reviewing the adjusted allocated radio resources according to base stations (BS1, . . . BSN) feedbacks.

A method for radio resources management within a set of cells (C1, . . . , CN) covered by base stations (BS1, . . . , BSN), the method comprising:
- retrieving traffic demands information including Quality of Service (QoS) and radio performance figures on each cell (Ci) of said set from correspondent base stations (BSi);
- processing the traffic demands information so as to detect at least one periodic traffic pattern by identifying a stable traffic periodic slot within the detected in at least one periodic traffic pattern, wherein the stable traffic periodic slot is a time period during which variation in the traffic activity is below a predetermined threshold;
- for each identified stable periodic slot, adjusting allocated radio resources for one or more cells of said set (Ci) according to the detected at least one periodic traffic pattern;
- and
- reviewing the adjusted allocated radio resources according to feedbacks from the base stations (BS1, . . . , BSN).
A cells controller for radio resources management within a set of cells (C1, . . . , CN) covered by base stations (BS1, . . . , BSN), the cells controller comprising:
- a processor configured to:
- retrieve information on traffic demands including Quality of Service (QoS) and radio performance figures on each cell (Ci) of said set from correspondent base station (BSi);
- analyze the information on traffic demands so as to detect periodic traffic patterns by identifying a stable traffic periodic slot within a detected periodic traffic pattern, wherein the stable traffic periodic slot is a time period during which variation in the traffic activity is below a predetermined threshold;
- for each identified stable traffic periodic slot, adjust allocated radio resources for one or more cells of said set (Ci) according to the detected periodic traffic patterns;
- collect feedbacks from the correspondent base stations (BSi, . . . , BSN) concerning the adjusted allocated radio resources.
A computer program embodied on a non-transitory memory of a computer and/or a dedicated system for radio resources management, wherein said computer program comprises instructions causing a processor to perform a method for radio resources management within a set of cells (C1, . . . , CN) covered b base stations (BS1, . . . , BSN), the method comprising:
- retrieving traffic demands information including Quality of Service (QoS) and radio performance figures on each cell (Ci) of said set from correspondent base stations (BSi);
- processing the traffic demands information so as to detect at least one periodic traffic pattern by identifying a stable traffic periodic slot within the detected in at least one periodic traffic pattern, wherein the stable traffic periodic slot is a time period during which variation in the traffic activity is below a predetermined threshold;
- for each identified stable periodic slot, adjusting allocated radio resources for one or more cells of said set (Ci) according to the detected at least one periodic traffic pattern;
- and reviewing the adjusted allocated radio resources according to feedbacks from the base stations (BS1, . . . , BSN).
