Method for enhanced performance of a telecommunications network, wherein the telecommunications network comprises at least one group of pooled mobility management entities, wherein the at least one group of pooled mobility management entities comprises at least a first mobility management entity and a second mobility management entity, wherein the first mobility management entity acts as a default mobility management entity that has the task of propagating any update configuration data to all the other mobility management entities in the pool, wherein in case the first mobility management entity is the one that receives update configuration data, the corresponding new configuration content is propagated to the other mobility management entities and wherein in case a non-default mobility management entity is the one that receives the update configuration data, the corresponding new configuration content is first transmitted to the first mobility management entity, and then propagated to the other mobility management entities, wherein the first mobility management entity comprises first configuration data and the second mobility management entity comprises second configuration data, wherein the method comprises at least one of the following steps: -- a first step in which new configuration content is propagated from the first mobility management entity to all the other mobility management entities in the pool, wherein the first step comprises a first sub-step, a second sub-step, a third sub-step and a fourth sub-step, wherein in the first sub-step, the first mobility management entity receives the update configuration data, wherein in the second sub-step, subsequent to the first sub-step, the first configuration data of the first mobility management entity - prior to receiving the update configuration data - are at least in part replaced or modified by the update configuration data, the first configuration data thereby becoming updated first configuration data, wherein in the third sub-step, either the update configuration data, or at least part of the updated first configuration data are transmitted to the second mobility management entity, and wherein in the fourth sub-step, subsequent to the third sub-step, the second configuration data of the second mobility management entity - prior to receiving the update configuration data or at least part of the updated first configuration data - are at least in part replaced or modified by the update configuration data or by the at least part of the updated first configuration data, the second configuration data thereby becoming updated second configuration data, wherein the first step comprises - based on the update configuration data received by the first mobility management entity - conducting the third sub-step and the fourth sub-step with respect to each mobility management entity in the group of pooled mobility management entities, -- a second step comprises - upon the second mobility management entity being either -- restarted and/or -- updated and/or -- added to the group of pooled mobility management entities - the second mobility management entity receiving startup configuration data from the first mobility management entity, the startup configuration data being part of the first configuration data or being part of the updated first configuration data of the first mobility management entity. -- a first step in which new configuration content is propagated from the first mobility management entity to all the other mobility management entities in the pool, wherein the first step comprises a first sub-step, a second sub-step, a third sub-step and a fourth sub-step, wherein in the first sub-step, the first mobility management entity receives the update configuration data, wherein in the second sub-step, subsequent to the first sub-step, the first configuration data of the first mobility management entity - prior to receiving the update configuration data - are at least in part replaced or modified by the update configuration data, the first configuration data thereby becoming updated first configuration data, wherein in the third sub-step, either the update configuration data, or at least part of the updated first configuration data are transmitted to the second mobility management entity, and wherein in the fourth sub-step, subsequent to the third sub-step, the second configuration data of the second mobility management entity - prior to receiving the update configuration data or at least part of the updated first configuration data - are at least in part replaced or modified by the update configuration data or by the at least part of the updated first configuration data, the second configuration data thereby becoming updated second configuration data, wherein the first step comprises - based on the update configuration data received by the first mobility management entity - conducting the third sub-step and the fourth sub-step with respect to each mobility management entity in the group of pooled mobility management entities, -- a second step comprises - upon the second mobility management entity being either -- restarted and/or -- updated and/or -- added to the group of pooled mobility management entities - the second mobility management entity receiving startup configuration data from the first mobility management entity, the startup configuration data being part of the first configuration data or being part of the updated first configuration data of the first mobility management entity.
