In one aspect there is a method for detecting whether a first system should be declared as an impostor. In one embodiment, the method includes generating baseline system output information using first system input; exposing the first system to the first system input; obtaining first system output information generated by the first system based on the first system's exposure to the first system input; determining a first similarity measure that indicates a similarity between the baseline system output information and the first system output information generated by the first system; and using the first similarity measure, determining whether or not to declare the first system as an impostor.

A method for operating a telecom network having an SLA agreement is disclosed. The method comprises obtaining annotated alarm data comprising an indication of a threshold crossing of at least one state variable of the telecom network defined by the SLA. The annotated alarm data further comprises an indication of a desired value of the at least one state variable of the telecom network. Moreover, the method comprises determining a desired state of the telecom network based on the desired value of at least one state variable, and selecting a set of policy actions from a policy action bank. The policy action bank comprises a plurality of policy actions, where each policy action is associated with at least one estimated action effect. The selection of the set of policy actions is accordingly based on the estimated action effects of the plurality of policy actions and on the determined desired state of the telecom network such that the desired state is reachable upon execution of the selected set of policy actions. The method further comprises sending the selected set of policy actions to an action orchestrating module for execution of the selected set of policy actions. Moreover, a corresponding computer program product and system are disclosed.

Methods provide wireless communication using a plurality of Antenna Processing Units APUs distributed along a radio stripe and sharing a bus along the radio stripe. Access is provided to a plurality of APU activation/deactivation states for a respective plurality of environmental conditions, wherein each one of the plurality of APU activation/deactivation states defines APUs of the plurality of APUs that are activated and APUs of the plurality of APUs that are deactivated for the respective one of the plurality of environmental conditions. Responsive to detecting a first one of the plurality of environmental conditions, a first one of the plurality of APU activation/deactivation states corresponding to the first one of the plurality of environmental conditions is applied to activate a first subset of the APUs and to deactivate a second subset of the APUs, wherein the first and second subsets of APUs are mutually exclusive.
