Abstract: Methods, systems, and devices are described for wireless communication. A wireless device such as an in-vehicle system (IVS) may transmit an emergency call (eCall) message to a third party eCall server using a communication session which may be packet based or circuit based. The eCall message may include session information and telematics data. The third party eCall server may relay the session information and telematics data to a public safety answering point (PSAP). For example, the third party eCall server may generate an automatic text-to-speech message that is transmitted to the PSAP over a public communications network. In some cases, the third party eCall server may transmit a response to the wireless device including metadata based on the telematics data transmitted in the eCall message. The eCall message may also include a call-back number, and the PSAP may contact the wireless device directly using the call-back number.

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.
