Abstract
Methods and apparatuses for supporting location and emergency calls for an over-the-top (OTT) service provider are disclosed. A UE may send a request for an emergency call to an OTT service provider and may include in the request mobile network operator (MNO) data for a serving MNO for the UE. The OTT service provider may forward the emergency call request to an Internet Protocol (IP) Multimedia Subsystem (IMS). The IMS may determine routing information for the emergency call and either return the routing information to the OTT service provider to enable the OTT service provider to route the emergency call to a public safety answering point (PSAP) or may route the emergency call itself to the PSAP. The call request routed by the IMS or by the OTT service provider may include a reference identifier that may enable the PSAP to obtain a location for the UE from the IMS.
