Abstract
In some examples, a user equipment (UE) is capable of dual registration with a first core network and a second core network. The UE receives a first indication during a first registration of the UE via a first access network with the first core network, determines based on the first indication that emergency services are not supported by the first core network, attempts a second registration via a second access network with the second core network, detects an emergency indication, and initiates a call in response to the emergency indication via a second access network different from the first access network.
