Abstract: Methods and systems for authenticating devices using 3GPP network access credentials for providing MEC services. A device is configured to receive MEC services from an EAS through 5G S A or NSA architecture. The device is authenticated by an ECS, which involves validating a MAC generated by the device. The MAC is validated using an edge authentication key, which is generated based on 3GPP network access security credentials of the device. The device is authorized by an EES to receive MEC services, which involves successful registration of the device with the EES and the EES providing credentials to the device for accessing an EAS providing desired MEC services. The EAS provides the desired MEC services to the device if the device provides credentials to the EAS, which are same as those provided to the device by the EES.

Abstract: Methods for handling Media-based Modulation (MBM) in a wireless network (1000) by a Mission Critical (MC) Gateway (GW) User Equipment (UE) (300) are provided. The method includes storing information associated with an identifier at the MC gateway UE (300) in response to receiving an MC gateway Multimedia Broadcast Multicast Services (MBMS) bearer announcement from an MC client (100). The MC gateway UE (300) uses the identifier and the information to activate for monitoring the MBMS bearer by the MC gateway UE (300). Further, the method includes sending an MBMS listening status report to the MC client (100) based on the MC GW MBMS bearer announcement. Further, the method includes establishing a communication channel with the MC client (100) based on a parameter to receive an MC service data from the MC gateway UE (300), where the MC gateway UE (300) forwards the MC service data to the MC client (100).

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 provide method and system for end-to-end security over signaling plane in a mission critical data (MCData) communication system. The proposed method includes various ways of securing MCData data payload transmitted over signaling plane using short data service (SDS). The proposed method allows usage of multiple security keys to encrypt the MCData SDS message as per the requirements. Various Keys such as, signaling plane key or media plane key or a dedicated MCData data payload signaling key can be used independently or in a combination thereof to achieve the desired security context. The proposed method allows protection of all the application level components with the signaling plane security context.

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. Example embodiments initiate a Mission Critical data (MCData) communication using a pre-established session. A participating MCData server receives at least one pre-established session setup request from an originating MCData client device. The pre-established session setup request comprises the pre-established session indication advising the participating MCData server of initiation of at least one pre-established session. The participating MCData server initiates the at least one pre-established session with the originating MCData client device based on the pre-established session indication. The participating MCData server sends at least one MCData-communication-state message to the originating MCData client device.
