Abstract: A method for communication by an electronic device is provided. The method comprises determining establishment of a data channel during an ongoing call with another electronic device; determining at least one application displayed on the electronic device and the another electronic device over the data channel during the ongoing call; determining a disconnection of the ongoing call between the electronic device and the another electronic device; and storing (508) a state of the at least one application in a memory of the electronic device based on determining the disconnection of the ongoing call, wherein the stored state of the at least one application is used for execution of the at least one application during another call.

Abstract: 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.

Abstract: The present invention generally relates to system and methods to avoid/reduce delay with SMS delivery in Dual SIM Dual Standby (DSDS) devices. As per the proposed solution, retry timer is stopped once Refresh Register is received for SIM-2 (i.e. Stand by SIM) to indicate the service resume and delivery the SMS immediately. The proposed solution has scope of Change Request with 3GPP to update the SMSC retry algorithm based on Refresh Register from service resumed SIM.
