1. A method comprising:
requesting, by a user equipment that is roaming among a plurality of visited mobile networks, registration for a network connection associated with a slice type;
obtaining, by the user equipment from a home mobile network for the user equipment, a priority for each of the plurality of visited mobile networks and an indication of one or more slice types provided by each of the plurality of visited mobile networks, wherein the priority for each of the plurality of visited mobile networks is associated with a time factor;
selecting, by the user equipment, based on the obtained priority for each of the plurality of visited mobile networks, the obtained indication of the one or more slice types provided by each of the plurality of visited mobile networks, and a time at which the user equipment requests the registration for the network connection, a highest priority visited mobile network of the plurality of visited mobile networks that provides the slice type; and
establishing, by the user equipment, the network connection with the highest priority visited mobile network of the plurality of visited mobile networks that provides the slice type.
