In some embodiments, the UE may be configured to support emergency calls in accordance with a 3GPP protocol and with eCall in an IP Multimedia Subsystem (IMS) session. The UE may comprise hardware processing circuitry configured to transmit traffic packets to an Evolved Node-B (eNB) for forwarding to a receiving station, which may be a Public Safety Answer Point (PSAP). In some embodiments, the transmission of traffic packets during a packetization period may be restricted to one of transmission of voice packets or transmission of data packets. In some embodiments, at least some of the data packets may include Minimum Set of Emergency Related Data (MSD), and the IMS session may be configured in accordance with Real Time Transport Protocol (RTP)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"User equipment (UE) supporting packet-switched emergency calls over IP multimedia subsystem (IMS)","description":"Embodiments of a mobile device, a User Equipment (UE), and method for supporting emergency calls on a packet-switched network are generally described herein.
