In one embodiment, a network assurance system that monitors a network forms a cluster of similarly behaving wireless access points (APs). The cluster includes APs associated with different software versions. The network assurance system trains a machine learning-based failure prediction model for the cluster based on a set of features of the APs in the cluster. The network assurance system proactively triggers a client in the network to roam from a first AP to a second AP, based on the failure prediction model predicting a failure of the first AP. The network assurance system quarantines the failure prediction model when a new software version is associated with one or more of the APs.

The present disclosure relates to a booster radio base station, booster RBS, defining a booster cell in a multilayer cell structure and a method, performed in a booster RBS, of controlling energy consumption. The method comprises a step of receiving (S21) information from a macro RBS, defining a basic coverage providing macro cell, the information indicating a first power required to provide service to one or more wireless devices being served in an area at least in part overlapping the booster cell. The method also comprises the further steps of determining (S23) a macro bitrate power measure based on the received information, the macro bitrate power measure reflecting a service provisioning of the one or more wireless devices from the macro RBS and determining (S25) a booster bitrate power measure, the booster bitrate power measure reflecting a service provisioning of the one or more wireless devices from the booster RBS. An energy consumption state is selected (S27) from two or more energy consumption states for the booster RBS based on a comparison between the booster bitrate power measure and the macro bitrate power measure. The disclosure relates to a method, performed in a macro radio base station, macro RBS, defining a basic coverage providing macro cell, of controlling energy consumption of a booster radio base station.

A method for establishing a self-organized emergency mobile core in a cellular communication network, the cellular communication network having a core element. The method includes the step of storing program code for implementing core network functionality on at least one stationary network element of the cellular communication network allowing to host virtual network functionality. The core network functionality remains inactive when the core element is available. The method includes the steps of detecting an emergency event within the cellular communication network resulting in an unavailability of the core element, and starting operating the core network functionality in order to establish a self-organized emergency mobile core in response to the detected emergency event.

A Machine-to-machine (M2M) terminal (11) comprises a radio communication unit (111) and a controller (112). The radio communication unit (111) is configured to communicate with a base station (13). The controller (112) is configured to change at least one of a cell selection operation, a cell reselection operation, and a handover operation according to whether a specific coverage enhancement processing is required or according to whether the specific coverage enhancement processing is supported by at least one of a cell (13) in which the M2M terminal (11) camps on and a neighboring cell (14) of the cell (13) which the M2M terminal (11) camps on. It is thus possible to provide an improved technique for allowing the M2M terminal that is supporting a special coverage enhancement processing for M2M terminals to camp on an appropriate cell.

Data distribution between mobile stations and external data paths is assigned to a new set of devices, distribution points. Each distribution point is independently coupled to mobile stations, also assigned to access points. Control elements operate to control the distribution points separately from the access points. Each access point maintains a substantially stateless link with each distribution point for which the two share a mobile station. Access points might exchange data with any one or more distribution points concurrently. Access points thus obtain greater bandwidth connectivity to external data paths. Mobile stations transfer between access points and transfer between distribution points independently. This has the effect that bandwidth connectivity between distribution points and external data paths have no particular requirement for VLAN separation. Mobile stations may roam among multiple Internet protocol subnets.
