Enhancement of normal call domain conflict resolution during emergency call

A method, comprising:

• establishing a first call having between a user equipment (UE) and a wireless network on an Internet Protocol (IP) Multimedia Subsystem (IMS) domain via a New Radio (NR) radio access technology (RAT);
• attempting to establish a second call between the UE and the wireless network via the NR RAT;
• and
• establishing the second call via a Long-Term Evolution (LTE) RAT responsive to a failure in attempting to establish the second call via the NR RAT,
• wherein the establishing of the second call comprises transferring the first call on the IMS domain to the LTE RAT along with establishing of the second call via the LTE RAT,
• wherein the establishing of the second call further comprises placing the first call in a hold state, and
• wherein the transferring of the first call comprises;
• triggering a scan on the LTE RAT while the first call is in the hold state;
• and
• performing a context transfer of the first call to an LTE domain corresponding to the LTE RAT responsive to a successful result of the scan on the LTE RAT.

An apparatus implementable in a user equipment (UE), comprising:

• a transceiver configured to communicate wirelessly;
• and
• a processor coupled to the transceiver and configured to perform operations, via the transceiver, comprising:
• after a first call having been established between the UE and a wireless network on a domain via a first radio access technology (RAT), attempting to establish a second call between the UE and the wireless network via the first RAT;
• and
• establishing the second call via a second RAT different than the first RAT responsive to a failure in attempting to establish the second call via the first RAT,
• wherein the establishing of the second call via the second RAT comprises transferring the first call on the domain to the second RAT along with establishing of the second call via the second RAT,
• wherein the establishing of the second call further comprises placing the first call in a hold state, and
• wherein the transferring of the first call comprises:
• triggering a scan on the second RAT while the first call is in the hold state;
• and
• performing a context transfer of the first call to another domain corresponding to the second RAT responsive to a successful result of the scan on the second RAT.
