FIRST CORE NETWORK TO SECOND CORE NETWORK INTERWORKING WHILE REDUCING USAGE OF DEFAULT SECOND CORE NETWORK RESOURCES

摘要

A method, system and nodes are disclosed. In some embodiments, a mobility control node of a first core network is configured to select a second node in a second core network for a handover of a user equipment, UE, to the second core network using at least a portion of network slicing related information associated to a Packet Data session established by the UE over the first core network, the selecting the second node using the at least a portion of the network slicing related information being configured to avoid use of a default second node resource for the handover of the UE to the second core network; and provide to the selected second node in the second core network, at the handover of the UE, the network slicing related information.
