1. A method for anticipating impacts on service levels of one or more services provided to a User Equipment, UE, while the UE moves along a planned route, each of the one or more services being provided to the UE using a network slice in a network slicing based mobile communication system, the method being performed by an anticipation component and comprising:
receiving a service level anticipation request for the planned route of the UE;
triggering determining an expected impact on the service levels of the one or more services at one or more locations of the planned route;
triggering sending a response to the service level anticipation request including information on the expected impact on the service levels to the UE, wherein the response comprises a list of entries, each entry of the list of entries contains a network slice identifier associated with a location in which the impact is expected to occur, wherein the information on the expected impact on the service levels included in the response to the service level anticipation request comprises, for each of the one or more services for which a negative impact on a first service level is determined in at least one geographical region, an indication of the at least one geographical region and an indication of the expected negative impact on the first service level of the respective service in the at least one geographical region; and
transmitting, to the UE, information to enable mitigating the negative impact on the service level in the area ahead of the UE, wherein the information to enable mitigating the negative impact on the service level in the area ahead of the UE is associated with downloading data to be provided to the UE before the UE enters the area on which the first service level is disrupted.
