A 3GPP 4G Evolved Packet Core-based system architecture for QoS-enabled mobile video surveillance applications

摘要

Mobile video surveillance applications have become ubiquitous and are used in both civilian and military settings. They enable the capture, storage and transmission of video images over the Internet or other networks. This paper proposes a novel system architecture for mobile video surveillance applications. We leverage the 3GPP 4G Evolved Packet Core (EPC) to enable features such as guaranteed quality of service (QoS), which is not possible with the Internet, and even differentiated QoS, which is not possible with the other networks currently used in mobile video applications. The key components of our proposed architecture are the service development platform (SDP) and the machine to machine (M2M) gateway. The SDP enables the development and management of QoS-enabled mobile video surveillance applications. The M2M gateway enables interactions with the M2M devices, such as motion detectors and cameras. We have built a prototype with the Fraunhofer Fokus OpenEPC as 3GPP 4G EPC infrastructure and three AXIS network cameras as M2M devices. The architecture is presented along with the prototype.
