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.

摘要： Embodiments herein provide a method for performing multiple authentications within a service registration procedure. The method includes sending, by a User Equipment (UE) a REGISTER request message to an IP Multimedia Subsystem (IMS) server. Further, the method includes receiving, an IMS authentication challenge from the IMS server, where the IMS authentication challenge includes an IMS authentication parameter and a MCPTT authentication challenge. Further, the method includes verifying, at the UE, the IMS authentication challenge. Further, the method includes generating, at the UE, a REGISTER response message. Further, the method includes sending, a REGISTER response message to the IMS server, where the REGISTER response message includes an IMS authentication response to authenticate UE at the IMS server and a MCPTT authentication response to authenticate the UE at the MCPTT server.

摘要： Embodiments herein provide a method for identity management across multiple planes. The method includes receiving, by a MCPTT server, a first request message to establish a call between a first MCPTT client and the one or more second MCPTT client from a signaling plane entity. The first request message includes an application plane identity of the one or more second MCPTT client. Further, the method includes translating, at the MCPTT server, the application plane identity of the one or more second MCPTT client to a signaling plane identity of the one or more second MCPTT client. Furthermore, the method includes sending, by the MCPTT server, the one or more second request message including the signaling plane identity of the one or more second MCPTT client to the second MCPTT client for establishing the call via the signaling plane entity.

摘要： The present disclosure provides a method and system for audio cut-in functionality in a mission critical push-to-talk (MCPTT) system. The method includes receiving, by a floor control server, a first floor request message, from a primary floor participant while a floor is granted to a secondary floor participant, applying, by the floor control server, an audio cut-in policy, granting, by the floor control server, the floor to the primary floor participant while terminating a media transmission of the secondary floor participant by revoking the floor from the secondary floor participant, and transmitting, by the floor control server, a first floor taken message to the secondary floor participant, wherein the first floor taken message includes information of the primary floor participant.

摘要： 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.

摘要： 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.
