Abstract: A method for a data session switching by a User Equipment (UE) is provided. The method includes monitoring network broadcasted parameters of a second Subscriber Identity Module (SIM) of the UE while performing a Fifth Generation Cellular Network (5G) data session over a first SIM of the UE, where the first SIM is configured for a Default Data Service (DDS), detecting that a trigger criterion is met for the 5G data session switching to the second SIM based on the network broadcasted parameters, and in response to the trigger criterion being met, configuring the second SIM for the DDS for continuing the 5G data session over the second SIM.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as long term evolution (LTE).
Embodiments herein provide a method for providing voice call and data service simultaneously on plurality of SIM in EN-DC capable UE. The method includes registering a first SIM to a first network in a DCNR supported mode using a T1 and registering a second SIM to a second network in the DCNR not supported mode using a T2. The method also includes determining a 4G bearer is established on the T1 and a 5G bearer is established on the T2 by the first network using the first SIM. Further, the method also includes determining the voice call is being initiated on the second SIM when the data service is active on the first SIM through the T1 and the T2; and configuring the second SIM to provide the voice call over the T2 and the first SIM to provide the data services over the T1.

Abstract: Provided is a method performed by a user equipment (UE) in a wireless communication system supporting Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN) New Radio (NR)-Dual Connectivity (ENDC). The method includes: receiving system information including information on an NR band list supported in the ENDC; identifying, based on the system information, NR bands supported at LTE frequencies of Long Term Evolution (LTE) bands in a most recently used (MRU) LTE frequency list of the UE; prioritizing the LTE frequencies in the MRU LTE frequency list, based on the supported NR bands and an ENDC capability of the UE; and performing a cell selection based on the prioritized MRU LTE frequency list.
