1. A method comprising:
receiving, by a first base station from a core network entity, a first message indicating a request for session resources for a wireless device, wherein the session resources are for a first network slice;
initiating, by the first base station and based on the requested session resources for the first network slice not being available for the wireless device at the first base station, a handover for the wireless device towards a first cell of a second base station;
sending, from the first base station to the second base station and after a determination that the requested session resources for the network slice associated with the first base station are not available for the wireless device, a request for the handover of the wireless device, the request comprising:
a packet flow identifier of a packet flow associated with the first network slice;
a network slice identifier of the network slice for the handover; and
a cause information element indicating that a cause for the handover is that the session resources are not available at the first base station for the network slice associated with the network slice identifier; and
receiving, from the second base station, a response to the request.
