For the purposes of the present document, the terms and definitions given in TR 21.905
and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905
Energy conservation mode (for load re-distribution):
an operational state, subject to implementation, of an EPC node with reduced capacity (e.g. in terms of number of users to be handled) or performance (e.g. in terms of data rate for user plane handling), requiring less power than in normal operational state. Subject to implementation, a node in energy conservation mode may reduce its capacity/performance to zero.
Suspension mode (for load re-distribution):
an operational state of an EPC node where load needs to be reduced (by re-distribution to alternative nodes). While in suspension mode, this node will not be selected to handle further users. In the context of this technical report, suspension mode is used to enable load redistribution for energy saving reasons.
