User equipment (UE) supporting packet-switched emergency calls over IP multimedia subsystem (IMS)

摘要

Embodiments of a mobile device, a User Equipment (UE), and method for supporting emergency calls on a packet-switched network are generally described herein. 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).

主权项

1. A mobile device configured to support packet-switched communication, the mobile device comprising:
a memory; and hardware processing circuitry coupled with the memory and configured to:
establish, with a receiving station, an emergency packet-switched communication session that enables transmission of traffic packets within a plurality of packetization periods of the communication session, a plurality of the traffic packets transmitted during at least one of the packetization periods;enable transmission within the communication session to include both data traffic and voice traffic packets; andafter transmission of at least one of each of the data traffic and voice traffic packets, restrict transmission within the at least one of the packetization periods of the communication session to one of data or voice packets, wherein restriction to one of transmission of voice packets or transmission of data packets occurs when an allocated data throughput for the communication session is less than a required data throughput for transmission of voice packets and data packets during the packetization period.
