• The emergency call (eCall) service is an important part of the mobile communication networks since helps mobile users to be able to communicate during alert circumstances. eCall services were already widely used by 3G networks and can be utilized by 4G Long-Term Evolution (LTE) networks as well as by Wireless Local Network (WLAN) networks, both of them using IP Multimedia Subsystem (IMS) core. The present paper provides a guideline about how eCall services are used in Voice over Long-Term Evolution (VoLTE) and Voice over Wi-Fi (VoWiFi) technologies over IMS. Furthermore, the work assesses the Quality of Service (QoS) of calls over VoLTE and VoWiFi. Additionally, using a packet analyzer software, there were analyzed in detail the Session Initiation Protocol (SIP) message headers, the way each technology collects the information of the user location and the signaling process for eCall over VoLTE and VoWiFi.
