Abstract: A method performed by a user equipment (UE) having a plurality of subscriber identity modules (SIMs) comprising a first SIM and a second SIM, includes: performing a connection establishment procedure for a first call associated with the first SIM; detecting, while the first call is provided on the first SIM, an internet protocol multimedia subsystem (IMS) event associated with the second SIM; and based on the detecting the IMS event, enabling a cross-SIM calling for the second SIM based on information associated with the IMS event.

Abstract: A method for managing data channel communication by a user equipment (UE) is provided. The method includes determining transmit a root application request, transmitting the root application request comprising a first application type information element (IE) associated with the root application, based on determining to transmit the root application request, and receiving a root application response based on the first application type IE associated with the root application, in response to the root application request, wherein the root application response comprise at least one of a list of data channel applications, a root application version IE and a root application validity IE.

Abstract: A method performed by a first user equipment (UE) for transferring an internet protocol (IP) multimedia subsystem (IMS) data channel (IDC) session between UEs in a communication network system is provided. The method includes determining, by the first UE, that an IDC session has been established between the first UE and the second UE, wherein the first UE and the second UE is in an ongoing IDC call, detecting, by the first UE, that an IDC call is being initiated by a third UE, initiating, by the first UE, the transfer of IDC session application state data from the first UE to the third UE, while maintaining the ongoing IDC call between the first UE and the second UE, and transmitting, by the first UE, the IDC session application state data to the second UE such that the second UE continues from same IDC session state where the first UE left-off with the third UE based on the IDC session application state data after the transfer is completed.

Abstract: A method for optimizing cross Subscriber Identity Module (SIM) calling by a User Equipment (UE), comprising: detecting, by the UE, an event associated at the UE, and cross SIM calling is established at the UE; initiating, by the ePDG of the AP, an evolved Packet data gateway (ePDG) at a communication processor (CP) of the UE based on the call being established; and processing, by the CP of the UE, the cross SIM data packets using an IP security tunnel.

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: A method for managing communication in a user equipment including a plurality of subscriber identity modules (SIMs). The method includes detecting that a network service is unavailable to a first SIM among the plurality of SIMS and that a network service is available to a second SIM among the plurality of SIMS; detecting an availability of an in-device hotspot; and providing, to the first SIM for sending data to a network, an access to the in-device hotspot for using the network service available to the second SIM.

Abstract: Embodiments herein provide a method for handling IMDN message in a RCS system. The method includes sending, by a first electronic device 100a, an IMDN restore message to restore a content deleted by the first electronic device 100a to at least one second electronic device 100b-100n. The IMDN restore message comprises an IMDN type with an original IMDN identifier of the deleted content. Further, the method includes receiving, by the at least one second electronic device 100b-100n, the IMDN message from the first electronic device 100a. Further, the method includes determining, by the at least one second electronic device 100b-100n, the deleted content based on the IMDN identifier. Further, the method includes sending, by the at least one second electronic device 100b-100n, the deleted content to the first electronic device 100a.
