Abstract: The present disclosure provides system and method for network slicing at a network slice selection function (NSSF) network node, a 3GPP-defined 5G network function for selection of one of many slice instances available in an operator network, as per the user's service access request. The NSSF of a serving public land mobile network (PLMN) interfaces with access and mobility function (AMF) node of the serving PLMN and NSSF of home PLMN to service a set of functionalities including selecting a list of network slice instances serving a user equipment (UE), fetching the list of mapped network slice selection assistance information (NSSAI) for the given list of subscribed NSSAI from home NSSF of the subscriber, fetching the list of mapped NSSAI for the given list of configured NSSAI from home NSSF of the subscriber, and determining the list of AMFs to serve the UE based on tracking area wise AMF configuration.

Abstract: The present disclosure relates to a system comprising an alarm management module (AMM) that receives an alarm raised by an application running on a network function virtualization unit (NFVU) infrastructure, said NFVU infrastructure comprising a virtualization layer; and facilitates enrichment of the received alarm with NFVU infrastructure specific information based on a physical-and-virtual inventory associated with the NFVU infrastructure, said NFVU infrastructure specific information pertaining to hardware and virtual resources of the NFVU infrastructure that are involved in running said application.
