Title: HANDOVER IN A WIRELESS COMMUNICATION NETWORK WITH NETWORK SLICES
Abstract:
Embodiments herein relate to a method performed by a first radio network node (12) for handling mobility of a wireless device (10) in a communication network (1). The communication network (1) comprises 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 in the communication network (1). The first radio network node (12) transmits a message comprising information indicating one or more slice identities supported by the first radio network node (12) to a second radio network node (13) in the communication network: The first radio network node (12) receives a response message comprising information indicating one or more slice identities supported by the second radio network node (13) from the second radio network node (13) in the communication network. The first radio network node (12) further obtains a support indication indicating the slice ID the wireless device (10) supports, during a connection setup of the wireless device (10) to the network slice. The first radio network node (12) determines to initiate a mobility procedure towards the second radio network node (13) taking the information in the received response message and the obtained support indication into account.
