1. A method for use in a wireless device of acquiring system information associated with a core network, the method comprising:
receiving system information from a network node, the network node connected to one or more core networks, the system information including an indication of a network type for each core network of the one or more core networks, wherein each core network is either an enhanced packet system (EPS) core network or a fifth generation system (5GS) core network;
determining a capability of the wireless device for connecting to a EPS core network, a 5GS core network, or both; and
determining whether to connect to a core network of the one or more core networks based on the network type of the core network and the capability of the wireless device for connecting to the plurality of network types.
