    Abstract: This disclosure relates to a method of operating a cellular telecommunications network, the cellular telecommunications network including a first base station for a first mobile network operator, a second base station, and a management node, the management node being configured to determine, based on a tracking area code, whether a base station associated with the tracking area code supports a circuit switched voice service. The method can include determining that at least a part of the first base station should enter energy saving mode; in response to the determination, identifying an energy saving solution that ensures continuity of the first circuit switched voice service; causing reconfiguration of the first base station according to the identified energy saving solution so that: the first circuit switched voice service supported by the first base station enters energy saving mode and, the first base station uses a first tracking area code indicating that the first base station does not support the first circuit switched voice service; and continuing support of the first circuit switched voice service by the second base station, wherein the second base station uses a second tracking area code indicating that the second base station supports the first circuit switched voice service.
