Abstract: A method and system for authenticating application program interface (API) invokers using a common application program interface framework (CAPIF) is provided. The method includes establishing by a CAPIF core function (CCF) a secure Transport Layers Security (TLS) connection with at least one API invoker, on receiving a connection request from the at least one API invoker to access at least one service API on a CAPIF-2e interface. Further, the method includes determining by the CCF at least one security method to be used by the at least one API invoker for a CAPIF-2e interface security (C2eIS) of the at least one API invoker for accessing the at least one service API on a CAPIF-2e interface. The method further includes enabling the C2eIS by an API exposing function (AEF) the at least one API invoker based on the determined at least one security method.

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 (LTE). Embodiments herein disclose a method for providing dynamic information to an edge enabler client (140) running in a UE (100). The method includes receiving, by an edge enabler server (300), a subscription request for a dynamic information subscription from the edge enabler client (140). Further, the method includes creating, by the edge enabler server (300), the dynamic information subscription to provide the dynamic information to the edge enabler client (140) based on the dynamic information provided in the subscription request. Further, the method includes sending, by the edge enabler server (300), a subscription response to the edge enabler client running in the UE (100) in response to creating the dynamic information subscription.

Abstract: Methods and systems for authentication and establishment of secure connection for accessing edge computing services are provided. The method includes dynamically deriving a pre-shared key (PSK) and use the dynamically derived PSK for the authentication, while performing or before performing a secure connection establishment or while or before establishing a secure interface between a user equipment (UE), and a server, wherein the UE includes an Edge Enabler Client (EEC), and the server is an Edge Configuration Server (ECS). The method further includes deriving the PSK based on an Authentication and Key Management for Applications (AKMA) application key.

Abstract: Provided are methods and apparatuses for off-network key management in one-to-one mission critical data communication. A method includes initiating an off-network MCData service for the communication with an other client device, obtaining a MCData message including a MCdata protection key and an identifier of the MCdata protection key, in case that a valid MCdata protection key for the other client device is not available, and transmitting the MCData message to the other client device.

Abstract: Provided is an API invoker of performing an onboarding. The API invoker includes a transceiver and a processor coupled with the transceiver and configured to obtain, from a service provider, onboarding information including an onboarding credential and information of a CAPIF core function, establish a secure session with the CAPIF core function based on the onboarding information and control the transceiver to transmit, to the CAPIF core function, an onboard API invoker request message along with the onboarding credential and to receive an onboard API invoker response message based on a result of a validating the onboarding credential at the CAPIF core function.

Abstract: Embodiments herein achieve systems and methods for managing communication in a Mission Critical data (MCData) communication system. The proposed method and system provides file distribution and data streaming in the MCData communication system. The proposed method and system provides a functional model and mechanisms to support mission critical data services. The functional model to support file distribution and data streaming, and associated procedures including one-to-one, one-to-many, and group data communications. Further, the proposed method and system provides mechanisms for optimizing radio resource utilization and backhaul link utilization in the MCData communication system. The proposed method and system provides radio resource utilization of the PC5 interface for the MC service, when multiple group members are under a relay node. Further, the proposed method and system can be used to reduce number of unicast transmissions between the MCData server and the MCData UEs by local routing at the relay node.

Abstract: Embodiments herein disclose formats for MCData messages and notifications, and methods for coding (encoding and decoding) MCData messages and notifications in a MCData communication system. The method includes generating, by a first UE, an encoded MCData message or notification comprising of signaling payload and data payload content related to one or more MCData user payloads. Further the method includes deriving, by a second UE, the actual MCData messages or notifications by decoding the received encoded MCData messages or notifications. The formats for MCData messages and MCData notifications optimize control headers and allow maximum user data size that can be carried in a single message over signalling, which aids in sending multiple user payloads in a single message.
