Abstract: Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). Embodiments herein achieve methods for handling a service notification and configuration for an MBS in a 5G communication network by a UE. The method includes synchronizing an MBS service list in a USD with an available list of MBS services based on an indication. Further, the method includes determining at least one of at least one available MBS service or at least one unavailable MBS service in the USD. Further, the method includes performing at least one of: identifying at least one interested MBS service from the at least one unavailable MBS service and sending an interest indication message to a network entity, wherein the interest indication message comprises information associated with at least one interested MBS service or identifying at least one interested MBS service from the at least one available MBS service and triggering a service join procedure.
