Abstract
Methods are performed by a first radio node for handling mobility of a wireless device in a communication network having partitioned sets of functionalities. Each set of functionalities belongs to a network slice and is separated from other sets of functionalities out of a total set of functionalities. The first radio node transmits information indicating one or more slice identities supported by the first radio node to a second radio node. The first radio node receives information indicating one or more slice identities supported by the second radio node from the second radio node. The first radio node obtains a support indication indicating the slice ID the wireless device supports, during a connection setup of the wireless device to the network slice. The first radio node initiates a mobility procedure towards the second radio node taking the information in the received response message and the obtained support indication into account.
