Abstract
Systems and methods are disclosed herein for network-initiated slice-based handover in a cellular communications system. In one embodiment, a method in a cellular communications system comprises, at a network node in a core network of the cellular communications system, detecting a triggering event for a network slice handover for a session of a particular wireless communication device. The method further comprises, at the network node and responsive to detecting the triggering event, identifying a target network slice for the network slice handover and sending, to a Policy and Control Function (PCF) in the core network, a message that initiates a network slice handover of the session from a source network slice to the target network slice. The method further comprises, at the PCF, receiving the message that initiates the network slice handover and performing an action to cause the network slice handover.
