To provide techniques for supporting handover of an emergency call between wireless networks.
A UE may communicate with a first wireless network for an emergency call and may receive an indication to perform handover to a second wireless network. In an aspect, the UE may send a message including an emergency indication to initiate handover to the second wireless network. A designated network entity may recognize the emergency call on the basis of the emergency indication and may map the emergency indication to a local emergency number or an Emergency Session Transfer Number for SRVCC, which may be used to establish a new incoming call leg to a network server anchoring the emergency call. The UE may then communicate with the second wireless network via the network server for the emergency call after the handover.
