Abstract: Method, apparatuses, and computer program products provide means for monitoring time sources for nodes of a network and providing timing resiliency solutions. An example method includes: establishing time synchronization within a network comprising a plurality of nodes using a time source; receiving an indication regarding at least one of degradation or failure of the time source for at least one node; receiving an indication regarding at least recovery of the time source for the at least one node; and determining, within the network, an action to be taken to upon failure at the at least one node in response to the at least one of the degradation or the failure of the time source for the at least one node, where the action to be taken comprises instructing the at least one node to leverage either hold over functionality or a backup time source.

Abstract: Method, apparatus, computer program for a user equipment having at least two connections to at least two network nodes, where each connection corresponds to a different user identity, selecting by the user equipment one of the at least two network nodes to communicate exclusively with during one or more time intervals; and sending by the user equipment one or more messages toward the other ones of the at least two network nodes, the one or more messages indicating to the other ones of the at least two network nodes that the user equipment is unavailable for communication during the one or more time intervals.

Abstract: Disclosed is a method comprising estimating a time synchronization accuracy associated with a plurality of base stations comprising at least a first base station and a second base station based at least partly on one or more uncertainty factors determined by the terminal device, selecting the second base station from the plurality of base stations by comparing the estimated time synchronization accuracy associated with the plurality of base stations, and synchronizing a clock based on the selected second base station.
