Data Continuity During An Ongoing Priority Data Call Activity, Mahesh Telang, Shivank Nayak, Qin Zhang

Defensive Publications Series

Historically, voice calls were handled using circuit-switched sessions and data transfer was conventionally handled using packet-switched communication. However, increases in the speed and bandwidth of wireless communication systems have enabled packet-based applications to provide voice, video, and emergency calls. Interruptions in the packet-switched data transmission for voice, video, and emergency calls supported by protocols such as voice-over-Internet protocol (VoIP) are reduced or eliminated by differentiating between data calls and other data operations. Activities that cause data disruption during the data calls are then avoided or bypassed for these calls.
