Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure especially relates to method and system for providing simultaneous voice and data services in EN-DC capable UE.
The method includes the steps of determining whether a VOLTE service is available at the UE and automatically switching the UE from an EN-DC mode to a Single Radio Long Term Evolution (SRLTE)-ENDC mode in response to determining that the VOLTE is unavailable while the UE is operating in the EN-DC mode.

Embodiments herein provide a method for switching between a plurality of SIM networks by a multi SIM UE in a wireless communication network. The method includes determining, by the multi SIM that the multi SIM UE needs to initiate an active data session on a second SIM network based on one of a paging message received by the multi SIM UE from the second SIM network and at least one MO activity which needs to be delivered using the second SIM network. Further, the method includes sending, by the multi SIM UE, a leaving operator message to the first SIM network indicating that the multi SIM UE is leaving the first SIM network; and switching, by the multi SIM UE, from the first SIM network to the second SIM network by triggering procedures to initiate the active data session on the second SIM network.

Abstract: Embodiments herein achieve a method for handling registration and session management in a wireless communication system. The method includes registering, by a User Equipment (UE), with a first core network entity over a 3GPP access network and a non-3GPP access network. Further, the method includes triggering, by the UE, a registration procedure to a second core network over the 3GPP access network when a periodic timer of the UE expires in an OOS state. Further, the method includes receiving, by the UE, a non-access stratum (NAS) message, over the 3GPP access network, with an indication to register for the non-3GPP access network with the second core network entity. Further, the method includes reinitiating the registration procedure to register again for the non-3GPP access with the second core network entity through the non-3GPP access network.
