1. An apparatus, comprising:
at least one processor; and
at least one memory including computer program code,
wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:
receive signaling comprising mapping information that comprises a mapping between one or more resource allocation classes and one or more random access channel resources or parameters;
receive signaling comprising network slice mapping information that comprises a mapping between the one or more resource allocation classes and one or more network slices; and
transmit a radio resource control request, either:
using, for a mobile terminated call, random access channel resources or parameters corresponding, based on the received mapping information, to a resource allocation class, wherein the resource allocation class was received in a radio paging message initiating the mobile terminated call, or
using, for a mobile originated call, random access channel resources or parameters corresponding, based on the mapping information, to a resource allocation class corresponding, based on the network slice mapping information, to a requested network slice associated with the mobile originated call.
