Method and system for energy saving and minimizing interference level in a radio access node network deployment

A method for energy saving and minimizing interference level in a radio access node network deployment, comprising the switching on and/or switching off of RF transceivers of one or more radio access nodes of said radio access node network deployment, wherein said radio access node network deployment is arranged in a master/slave configuration wherein each node is suitable to be assigned, by means of an initial configuration, alternatively as a master or as a slave radio access node and in that the method comprises:

• bidirectionally exchanging information between a selected master radio access node of said radio access node network deployment and each of the selected slave radio access nodes, for at least:
• sending each assigned slave radio access node its traffic load information to an assigned master radio access node;
• and
• processing, the master radio access node the received traffic load information to calculate a decision parameter and further sending said decision parameter to the slave radio access nodes;
• and
• performing said switching on and/or switching off automatically by the slave radio access nodes, in an autonomous way where each slave radio access node is in charge to change its own transmission conditions, by means of a decision algorithm based on the received decision parameter.

A radio access node network deployment system for energy saving and minimizing interference level, comprising a plurality of radio access nodes with respective RF transceivers switchable on and off, wherein said radio access nodes are arranged according to a master/slave configuration, each radio access node is suitable to be assigned, by means of an initial configuration, alternatively as a master or as a slave radio access node and in that it comprises:

• means for bidirectionally exchanging information between a selected master radio access node of said radio access node network deployment and each of the selected slave radio access nodes, for at least:
• sending each assigned slave radio access node its traffic load information to an assigned master radio access node;
• and
• processing, the master radio access node, the received traffic load information to calculate a decision parameter and further sending said decision parameter to the slave radio access nodes;
• and
• control means for performing said switching on and/or switching off automatically by the slave radio access nodes of said radio access node network deployment, in an autonomous way where each slave radio access node is in charge to change its own transmission conditions, by means of a decision algorithm based on the received decision parameter, said control means including:
• first processing means included in said master radio access node implementing said decision algorithm for calculating said decision parameter;
• and
• second processing means included in each of said slave radio access nodes implementing said decision parameter for performing said switching on and off of its RF transceiver.
