1. A method for use in a wireless transmit/receive unit (WTRU), the method comprising:
determining, for a first application that is requesting network access, a classification associated with the first application;
determining, based on configuration information, a first service session continuity (SSC) mode for the first application, wherein the configuration information includes mapping information between the classification associated with the first application and the first SSC mode;
transmitting, based on the determined first SSC mode being different than a second SSC mode associated with an existing first Packet Data Unit (PDU) session, a first PDU session establishment request with the determined first SSC mode for a new second PDU session to be associated with the first application;
determining, for a second application that is requesting network access, a classification associated with the second application;
determining, based on the configuration information, a third SSC mode for the second application, wherein the configuration information further includes mapping information between the classification associated with the second application and the third SSC mode; and
transmitting, based on at least the determined third SSC mode being different than the first SSC mode associated with the second PDU session, a second PDU session establishment request with the determined third SSC mode for a new third PDU session to be associated with the second application.
