The disclosure relates to methods and system for handling immersive services with feature tags in an 3GPP IP multimedia subsystem (IMS) and 3GPP mission critical services (MCX). A user equipment uses the media tags, feature tags with unique IMS communication service identifier (ICSI) and IMS application reference identifier (IARI) to communicate with the IMS network for determining the immersive services in the communication. Accordingly, a method includes: performing, a registration with a network for handling immersive call services based on feature tags included in a session initiation protocol (SIP) REGISTER request; determining whether the network provides a provision for the handling of immersive call services based on an SIP REGISTER response; and sending an SIP INVITE request including feature tags to a second client device via the network based on determining that the network provides the provision of handling immersive media streams. Thus, the immersive call is established by the first client device with the second client device.
