1. A method performed at a wireless device for selecting a security gateway for access over a non-third Generation Partnership Project, Non-3GPP, access network, the method comprising:
obtaining information comprising security gateway of a first type information and security gateway of a second type information for enabling the wireless device to select the security gateway of a first type or the security gateway of a second type in a public land mobile network (PLMN), the information further comprising a service type and a PLMN preference for the security gateway of the first type or of the second type;
selecting, based on a requested service type and the PLMN preference, one of the security gateway of the first type or the security gateway of the second type that supports the requested service type for establishing a connection over the non-3GPP access network, wherein the security gateway of the first type provides access for the wireless device to a first type of 3GPP core network and the security gateway of the second type provides access for the wireless device to a second type of 3GPP core network; and
establishing a connection to the selected security gateway.
