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; and

    after 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.
