The Q4HEALTH project is an innovation action focused on the optimization of real time video for emergency services over LTE. The project is implemented as a set of experiments conducted over the FIRE platforms PerformLTE and OpenAirInterface. The motivation is to study video performance in scenarios with wearable live video for first responders, improving its response on LTE-A with a particular innovation focus on 3GPP release 12.
Q4HEALTH faces different challenges: the inability of applications to negotiate a QoS agreement with the network, the delays introduced on live video, the appropriate scheduling algorithms on the access nodes, the service availability on indoor scenarios and the communication between geographically correlated entities.
These challenges will be approached from different perspectives: the applications will be extended to provide information regarding the type of traffic as well as their traffic requirements to the Evolved Packet Core and the scheduler in the Radio Access Network; the radio access where different scheduling strategies will be explored for emergency video; and in the core network where mechanism to perform Quality of Service reservation techniques for seamless mobility between heterogeneous access technologies and Software Defined Network techniques to improve communication will be studied.
