Certain example embodiments provide systems, methods, apparatuses, and computer program products for emergency operations (e.g., Internet protocol multimedia subsystem (IMS) emergency calls) network slice exchange between entities in mobile networks. For example, a network node (e.g., a core network node, such as an access and mobility management function (AMF)) may provide, to a radio access network (RAN) node, information that identifies network slice(s) to be used for emergency operation(s).
