               1. A method, comprising: 
            sending, by a first service entity configured to manage a network slice instance, a first request to a second service entity configured to manage an alarm of a network function instance, wherein the first request requests a virtualized resource alarm, wherein the first request comprises an alarm filtering list, wherein the alarm filtering list comprises identifier information of one or more virtual network function (VNF) instances, wherein the one or more VNF instances corresponds to a first network slice instance managed by the first service entity, and wherein the alarm filtering list corresponds to the first network slice instance; 
                receiving, by the first service entity, a first response from the second service entity, wherein the first response comprises the virtualized resource alarm, and wherein the virtualized resource alarm comprises the identifier information of the VNF instance; 
                associating, by the first service entity based on the identifier information of the VNF instance, the virtualized resource alarm with the alarm filtering list carrying the identifier information of the VNF instance; and 
                associating, by the first service entity based on a first correspondence between the alarm filtering list and the first network slice instance, the virtualized resource alarm with the first network slice instance, wherein the first network slice instance is one of a plurality of network slice instances managed by the first service entity.
