The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein provide a method for handling functional alias in a conference event package in a wireless network by a server. The method includes detecting a group call associated with a group in the wireless network. Further, the method includes providing a SIP NOTIFY message comprising an ID of each member of a plurality of members of the group, and an IE indicating the functional alias bound by each member of the plurality of members with the group. Further, the method includes sending the SIP NOTIFY message to a client device corresponding to each member of the plurality of members of the group.

Method and system for handling functional alias in conference event package

In an example embodiment of present disclosure, a method and apparatus to exchange an SSRC value between a client and a server for implicit floor requests are disclosed. In an embodiment, the exchange of the SSRC value between the client and the server for implicit floor requests is being done with Explicit Grant Support during a Multi-Talker MCPTT call where the SSRC sharing in FMTP media attribute of Session Description Protocol (SDP). In an embodiment, exchange of the SSRC value between the client and the server for implicit floor requests is being done with Implicit Grant Support during a Multi-Talker MCPTT call where the SSRC sharing in FMTP media attribute of SDP. In an embodiment, exchange of the SSRC value between the client and the server for implicit floor requests is being done with Implicit/Explicit Grant Support during a Multi-Talker MCPTT call where the SSRC sharing in SSRC and FMTP media attribute of SDP.

Method and apparatus for communication in communication system supporting multi-talker mission critical push-to-talk (MCPTT)

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.

Method and apparatus for transmitting a mission critical data message in a communication system

Optimal network resource consumption by dynamically controlling media bursts in Simultaneous PoC (Push-To-X (Push-To-Voice/Video/etc.) Over Cellular) calls. Embodiments disclosed herein relate to wireless communication networks, and more particularly to PoC calls performed using wireless communication networks. Embodiments herein disclose methods and systems for optimal network resource consumption by dynamically controlling media bursts, when a user is participating in simultaneous PoC sessions. Embodiments herein disclose methods and systems for optimal network resource consumption by enabling a user to selectively enable/disable multiple PoC sessions using MBCP 'Activate' and 'Deactivate' messages.

Optimizing network resources usage by dynamically controlling media bursts in simultaneous push to talk over cellular (POC) calls

A method and an apparatus are provided for transmitting a mission critical data (MCData) notification message by a first user equipment (UE) in a communication system by generating an MCData notification message to share disposition information and transmitting the MCData notification message to a second UE. The MCData notification message includes at least one of a notification message identity information element to identify a type of the MCData notification message, a date and time information element to indicate a time when the MCData notification message was sent, a conversation identifier (ID) information element to identify a conversation, and a message ID information element to identify the MCData message within the conversation.

Embodiments herein provide a systems and methods for managing short data service (SDS) in on-network and off-network mission critical data (MC Data) communication system. The various embodiments provide one-to-one SDS and a group SDS in the on-network MC Data communication system for a unidirectional communication. The various embodiments provide one-to-one SDS and a group SDS in the on-network MC Data communication system for a bidirectional communication. Further, the various embodiments provide a one-to-one SDS and a group SDS in an off-network MC Data communication system for a unidirectional communication.

Method for managing short data service (SDS) in mission critical data (MC data) communication system

A method for associating services in an electronic device is provided. The method includes sending, by a first electronic device, a first service with a first private association dialog (PAD) to a second electronic device, wherein the first PAD of the first service includes a first PAD identifier and sending, by the first electronic device, a second service with a second PAD to the second electronic device, wherein the second PAD of the second service includes a second PAD identifier that matches the first PAD identifier to associate the second service with the first service at the second electronic device.
