Abstract
The embodiments herein relate to a method performed by a control plane node (303) for handling a UE (101) which roams into a visited network (100a). At least the network in which the control plane node (303) is comprised is a MSC network. The control plane node (303) transmits a create chain request message to a service chain controller (305). The create chain request message is a request to create a chain of UPF nodes (308) that user plane packets to or from the UE (101) should traverse. The control plane node (303) receives a create chain response message from the service chain controller (305). The create chain response message indicates that the requested chain has been created.
