In this paper we address the support of wearable mHealth applications in LTE and future 5G networks following a holistic approach that spans across the elements of a mobile network. The communication requirements change from one application to another so we propose a measurement methodology to facilitate the selection of the user equipment to fulfil these requirements. We also discuss a new network architecture to support traffic prioritization, RAN programmability, low latency and group communications to over-the-top applications. Our proposal is validated using several realistic experimentation platforms and the results show that mHealth systems can benefit from our approach. Read More Here
The changes in new mobile networks toward a full Internet protocol–based architecture have led to opportunities for service-oriented optimizations based on emergent technologies like fog computing, software-defined networking, or network function virtualization. This paper explores 2 ways of using these new technologies to reduce the latency in Long-Term Evolution (LTE) networks. Both solutions reduce the path that the data packets should follow from the base station (evolved Node B [eNB]) to the network components that connect to the servers. The first solution, called Fog Gateway, is based on the interception of the packets in the tunnel at the eNB and their redirection to local servers running the fog services. This solution is fully compliant with the current LTE architecture and only requires new components. The second solution, called General Packet Radio Service Tunneling Protocol Gateway (GTP), is based on splitting the eNB’s functionality to avoid unnecessary GTP encapsulation of the packets geared toward the fog services.

This chapter provides an overview of different scenarios that can be identified in emergency situations such as natural disasters or accidents, thus providing an overview of new services that might be beneficial for these scenarios as well as the major challenges that have to be addressed by public safety LTE networks to maintain communications in these situations. Additionally, a case study about a new video hardware platform to be used by first responders is introduced alongside new components to be included in the operators’ networks to provide these new services in the area of public safety.

Mission critical communications have been traditionally provided with proprietary communication systems (like Tetra), offering a limited set of capabilities, and mainly targeting voice services. Nevertheless, the current explosion of mobile communications and the need for increased performance and availability especially in mission critical scenarios, require a broad type of services to be available for these platforms. In this sense the LTE technology is very promising, as it provides mechanisms to enforce QoS, has standardized many useful functions in public safety scenarios (like group communications, positioning services, etc.), while it is being evolved to match future 5G requirements.

The upcoming 5G technologies promise to enable ultra low latency services such as remote robotics, augmented reality or vehicle to vehicle communications. Fog and MEC computing can enable low latency services for many different scenarios by moving the cloud and some network functions closer to the user. In the case of mobile networks this improvement is traditionally introduced in the reference point that defines the limit of the operator domain. In this paper we explore the introduction of an intermediate component in the LTE standard architecture, describing its functionality and providing experimental results on its use. This component, called Fog Gateway, can process the data plane for specific services to prevent all the traffic reaching the core network. Read more here.
Communications for emergency services have been traditionally provided with dedicated radio technology (like TETRA), however mobile communications are gaining more popularity for these scenarios due to their availability, price and spectrum usage. This trend will be more accentuated in the following years with the appearance of 5G systems, that promises better figures in almost all the Key Performance Indicators (KPIs) of the system. LTE can provide many of the functionalities required by emergency services and is currently being evolved toward the 5G era by incorporating heterogeneous networking, over the top applications, network function virtualization and more. Q4Health project is focused on the preparation for market of a video application for first responders based on LTE by designing and executing several novel experiments in order to optimize the communications for this platform.
