1. An apparatus comprising:
a transceiver that communicates with a mobile communication network using a plurality of network connections, each network connection associated with one of a plurality of protocol data unit (“PDU”) sessions over the mobile communication network, where each PDU session is associated to a different network slice type of the mobile communication network; and
a processor that:
receives a configuration for selecting a network slice type for traffic associated with a media type of an internet protocol multimedia subsystem (“IMS”) application;
receives a first request to establish an IMS session with an IMS network, the IMS network reachable via the plurality of PDU sessions, wherein the first request comprises a plurality of media types;
selects, for each media type of the plurality of media types, a PDU session to be used for communicating media traffic; and
transmits, using a first of the plurality of PDU sessions, an IMS session request message to the IMS network, wherein the IMS session request message indicates one or more parameters to be used for communicating the media traffic for each media type over the selected PDU session for that media type.
