Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution. Methods and systems for mitigating Denial of Service (DOS) attacks in wireless networks, by performing admission control by verifying a User Equipment's (UE's) registration request via a Closed Access Group (CAG) cell without performing a primary authentication are provided. Embodiments herein disclose methods and system for verifying permissions of the UE to access a CAG cell based on the UE's Subscription identifier, before performing the primary authentication. The method for mitigating DOS attacks in wireless networks includes requesting a public land mobile network for accessing a non-public network (NPN) through a CAG cell, verifying the permissions of a UE to access the requested NPN through the CAG cell, and performing a primary authentication.

Abstract: The present disclosure relates to method and a system for monitoring application services in network. The system comprises ASM client and ASM server. The ASM client is configured in UE to monitor parameters related to applications in UE. The ASM server monitors VAL server based on parameters associated with VAL server. The ASM server obtain status information of VAL server by performing either pull procedure, push procedure, and subscribe-notify procedure. Further, the ASM server provides the status information to one or more entities for performing one or more actions. Thus, the present disclosure facilitates the system to monitor the application services and indicate one or more entities to perform corrective actions to provide seamless and uninterrupted services to users.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Accordingly, the embodiments herein disclose a method for providing a generic framework to manage a custom subscription over a SIP. The method includes sending at least one request with a plurality of parameters to a server SIP node (200) for any type of data over a SIP regardless of an event package is available or not. The custom subscription is managed by one of creating the custom subscription, modifying the custom subscription, deleting the custom subscription, notifying the custom subscription, and terminating the custom subscription using the plurality of parameters. Further, the method includes providing a subscription for a location management service associated with the server SIP node (200) over the SIP regardless of the event package is available or not. The server SIP node (200) allows a client SIP node (100) to manage a location information using the plurality of parameters.

Abstract: Accordingly, embodiments herein disclose a method for handling a closed access group (CAG) related procedure in a wireless communication system. A network may receive a radio resource control (RRC) resume request message from a user equipment (UE). The network may determine whether the at least one CAG identifier (ID) broadcasted in a CAG cell is included in an allowed CAG list of the UE (100) in response to the RRC resume request message. The network may proceed with a RRC resume procedure in response to determining that the at least one CAG ID is included in the allowed CAG list.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system that supports higher data rates Beyond 4th-Generation (4G) communication system. A method includes receiving the registration request message from an AMF entity; validating the registration request message based on the security information; generating configuration information of at least one API provider domain function entity from the list of the API provider domain function entities that successfully registered with a CAPIF core function entity; sending the response message to the AMF entity; receiving the registration update request message from the AMF entity; validating the registration update request message based on the security information; updating configuration information of at least one API provider domain function entity from the list of the API provider domain function entities that successfully updated with the CAPIF core function entity; and, sending the registration update response message to the AMF entity.
