AI summary

There are provided measures for enabling/realizing energy saving in a service-based access network such as a service-based radio access network, particularly energy saving at a specified granularity in a service-based access network such as a service-based radio access network. Such measures exemplarily comprise that a node or element in the service-based access network captures an energy saving request or command of an energy saving service in the service-based access network, wherein the energy saving request or command enables that the specified granularity can be deduced, and is configured to request or command initiation of an energy saving mode, notifies one or more service consumer entities of initiation of the requested or commanded energy saving mode, and initiates the requested or commanded energy saving mode.
