Assignee: QUALCOMM INCORPORATED
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 13:
14. An apparatus for wireless communication, comprising:
a processor;
memory in electronic communication with the processor; and
instructions stored in the memory and executable by the processor to cause the apparatus to:
identify, at a first network device associated with a first radio access network (RAN), a user equipment (UE) connected to a source base station associated with the first RAN, wherein the first RAN is a Next Generation (NG) RAN;
receive, at the first network device, a handover message comprising a voice call continuity handover trigger message indicating a handover of the UE to a target base station associated with a GSM/EDGE Radio Access Network (GERAN) or a Universal Terrestrial Radio Access Network (UTRAN);
determine that a second network device supports a transmission of a bypass handover message, and has a backhaul connection with the target base station, wherein the bypass handover message indicates to bypass a handover of the UE from the source base station associated with the first RAN to the second network device, wherein the second network device is associated with an Evolved Universal Terrestrial Radio Access Network (E-UTRAN); and
transmit, from the first network device to the determined second network device, the bypass handover message based at least in part on the received handover message, the bypass handover message comprising the voice call continuity handover trigger message.
