First Claim
Patent Images
1. A method for managing the traffic of a network of a plurality of small cell base stations arranged in a macro-cell in which there is at least one terminal, each small cell base station being adapted to cover a small cell of the macro-cell, the method comprising the following steps:
- determining at least one possible connection between said at least one terminal and a small cell base station;
placing in a queue several data packets addressed to said at least one terminal, each data packet being defined by at least one priority level;
classifying the data packets as per their priority level;
the method, as soon as a data packet in the queue reaches a maximal priority level, further comprising the following steps;
selecting a small cell adapted to cover at least one first terminal to which the said data packet having a maximal priority level is addressed, called the priority terminal;
only the said selected small cell to become active;
determining a group to be transmitted of at least one data packet having a lower priority level than the maximal priority level and addressed to at least one second terminal present in said activated small cell, called the non-priority terminal, and/or addressed to said priority terminal;
connecting said priority terminal and/or said non-priority terminal to the base station of said active small cell;
routing the data packets of the said group to be transmitted towards the priority and non-priority terminals.

Abstract
The invention concerns a method for managing a network of a plurality of small cell base stations arranged in a macro-cell and linked to a base station of the macro-cell, each small cell base station being adapted to cover a small cell of the macro-cell and to be linked via radio to at least one mobile terminal present in the small cell.
