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.
