METHOD FOR AN IMPROVED OPERATION OF A BROADBAND ACCESS NETWORK OF A TELECOMMUNICATIONS NETWORK AND/OR FOR AN IMPROVED AND/OR MORE ENERGY EFFICIENT OPERATION OF THE BROADBAND ACCESS NETWORK, BROADBAND ACCESS NETWORK OR TELECOMMUNICATIONS NETWORK, AND SYSTEM, PROGRAM AND COMPUTER-READABLE MEDIUM
METHOD FOR AN IMPROVED OPERATION OF A BROADBAND ACCESS NETWORK OF A TELECOMMUNICATIONS NETWORK AND/OR FOR AN IMPROVED AND/OR MORE ENERGY EFFICIENT OPERATION OF THE BROADBAND ACCESS NETWORK, BROADBAND ACCESS NETWORK OR TELECOMMUNICATIONS NETWORK, AND SYSTEM, PROGRAM AND COMPUTER-READABLE MEDIUM
The invention relates to a method for an improved operation of a broadband access network of a telecommunications network and/or for an improved and/or more energy efficient operation of the broadband access network, the broadband access network comprising a central office point of delivery with a switching fabric, the switching fabric comprising a plurality of spine network nodes and a plurality of leaf network nodes, wherein the central office point of delivery and/or the broadband access network comprises a central power management entity or functionality and a session management entity or functionality, and wherein the plurality of spine network nodes and the plurality of leaf network nodes comprise, respectively, a local power management entity or functionality, wherein in order for an improved and/or more energy efficient operation of the central office point of delivery, and regarding a considered leaf network node of the plurality of leaf network nodes, the method comprises the following steps:-- in a first step, a traffic load information message regarding the current load situation of the considered leaf network node is transmitted, by the local power management entity or functionality of the considered leaf network node, to the central power management entity or functionality,-- in a second step, subsequent to the first step, the central power management entity or functionality transmits a session transfer request message to the session management entity or functionality, the session transfer request message corresponding to requesting permission to carry over one or a plurality of sessions handled by the considered leaf network node to another leaf network node of the plurality of leaf network nodes,-- in a third step, subsequent to the second step, the session management entity or functionality transmits a session transfer answer message to the central power management entity or functionality, the session transfer answer message corresponding to the session transfer request message,-- in a fourth step, subsequent to the third step, the central power management entity or functionality transmits a traffic load execution message to the local power management entity or functionality of the considered leaf network node, wherein, dependent on the content of the traffic load execution message, the considered leaf network node is controlled in order for an improved and/or more energy efficient operation.
