The disclosure relates to 5G/6G communication systems for supporting a higher data transmission rate. Embodiments provide a method for controlling an ad-hoc group communication with a security context for MCX services. The method includes sending, by first MC service client device, an ad-hoc group communication request message to an MC service server to establish the ad-hoc group communication with a second MC service client device. The MC service server determines whether the ad-hoc group communication is supported and successfully authorized based on the received ad-hoc group communication request. The method includes: receiving an ad-hoc group communication request return message from the MC service server when the ad-hoc group communication is supported and successfully authorized; generating the security context for the second MC service client device for the ad-hoc group communication; and establishing the ad-hoc group communication with the second MC service client device using the generated security context.

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

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Disclosed is a method for binding or unbinding a functional alias with at least one mission critical services (MCX) group in an MCX network, including creating or updating, by an MCX server, an association of a functional alias with the at least one MCX group when the SIP message request is received to create binding of the functional alias with at least one MCX group, or disassociating by the MCX server an association of the functional alias with the at least one MCX group when the SIP message request is received to remove the binding of the functional alias with the at least one MCX group, and sending, by the MCX server, an SIP message response to MCX client device confirming whether the creation or removal of binding of the functional alias with the at least one MCX group is successful or unsuccessful.

Method and system to create, update and remove the binding of functional alias with MCX group

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein disclose methods and systems for providing support for ad hoc group calls in mission critical services. The method includes listing, by an MCPTT client, a list of MCPTT participants or a functional alias to initiate an ad hoc group call in a MCX on network. The method further includes initiating, by the MCPTT client, the ad hoc group call with a list of MCPTT participants or the functional alias by sending a group call request to an MCPTT server.

Systems and methods for supporting ad hoc group call for MCX services

A method, performed by a mission critical data (MCData) message store entity, of depositing MCData for file distribution (FD). the method includes receiving a MCData deposit an object request message or a MCData retrieve file to store locally request message, wherein the MCData deposit an object request message comprises information regarding the object and the MCData retrieve file to store locally request message comprises information regarding object identifier, based on the MCData deposit an object request message or the MCData retrieve file to store locally request message, retrieving uniform resource locator (URL) of file content in a MCData content server, based on a result of the retrieving, fetching the file content from the MCData content server, storing the file content into a MCData user's storage area in the MCData message store entity, and updating the object with the URL referencing the file content stored in the MCData user's storage area.

Method and device for storing and distributing file content in mc network

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein disclose methods for location management in a wireless network by a MC client. The method includes receiving, by a MC client, at least one of a location reporting configuration request and a location information request from a location management server (LMS). Further, the method includes sending, by the MC client MC client, at least one of a MC gateway location reporting configuration request to a MC gateway UE based on the location reporting configuration request for an event triggered location reporting and a MC gateway location information request for an on-demand location to request a 3GPP access network related location information based on the location information request. Further, the method includes receiving a MC gateway location information report comprising location information requested by the MC client.
