US 11,445,359 B2 · Apparatus and method for providing voice call and data service simultaneously on plurality of 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.

Dependent claims

A method for providing a voice call and a data service in an Evolved-Universal Terrestrial Radio Access Network New Radio-Dual Connectivity (EN-DC) capable User Equipment (UE) supporting a plurality of Subscriber identity modules (SIMs), the method comprising:

registering a first SIM of the plurality of SIMs to a first network in a Dual Connectivity with NR (DCNR) supported mode using a first transceiver;
registering a second SIM of the plurality of SIMs to a second network in a Dual Connectivity with NR (DCNR) not supported mode using a second transceiver;
determining a split bearer established by the first SIM, wherein the split bearer establishment comprises a 4G bearer established on the first transceiver and a 5G bearer established on the second transceiver by the first network using the first SIM;
determining the voice call is initiated on the second SIM when the data service is active on the first SIM through the first transceiver and the second transceiver;
and
configuring the second SIM to provide the voice call over the second transceiver and the first SIM to provide the data services over the first transceiver simultaneously.
