1. A method performed by a core network apparatus, the method comprising:
receiving a registration request originated from a user equipment in a communication network;
constructing a registration accept message, wherein the registration accept message includes an indication comprising an access stratum connection establishment network slice selection assistance information (NSSAI) inclusion mode parameter, the access stratum connection establishment NSSAI inclusion mode parameter defining whether NSSAI should be included by the user equipment in an access stratum connection establishment procedure, wherein the access stratum connection establishment NSSAI inclusion mode parameter is derived based on a set of policies implemented in one or more radio access nodes in a registration area of the communication network;
causing transmission of the registration accept message towards the user equipment; and
receiving a connection establishment message originated from the user equipment according to the access stratum connection establishment network slice selection assistance information inclusion mode parameter.
