Method, apparatus and computer-readable medium for wireless communication

Abstract

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a first user equipment (UE). The first UE receives, during setup of an Internet Protocol (IP) Multimedia Subsystem (IMS) voice call with a second UE, signaling including a satellite cell global identifier associated with the second UE, an IP address of the second UE, and a data radio bearer (DRB) identity of the second UE for voice packets. The first UE determines that the first UE and the second UE are served by a same satellite and that no transcoding is required for the IMS voice call. The first UE transmits, to a satellite serving the first UE, a local turnaround request including DRB identities, IP addresses, and User Datagram Protocol (UDP) port numbers for the first UE and the second UE.
