To tackle these challenges, Telcos must provide flexible, dynamic network architecture, furnishing resiliency to ensure end-to-end (E2E) service continuity in case of resource failures. Virtualization of the core network elements...
Providing proper technical solutions to cover all requirements of the Voice over LTE (VoLTE) service is still a great challenge for operators. Network monitoring is one of the important methods to support service verification, deployment and operations. The VoLTE service utilizes both the LTE Evolved Packet Core (EPC), and the IP Multimedia Subsystem (IMS). These architectures are built on different...
Dedicated public safety systems have been originally used to deliver the communications for public services such as police and fire departments. These systems are based on standards such as Terrestrial Trunked Radio (TETRA) which have been designed to meet specifically the requirements of public safety communications. However, with the emergence of new applications requiring mobile broadband capabilities,...
In perspective, the effectiveness and attractiveness of multimedia communications rely both on such disruptive services as Web Real-Time Communication (WebRTC), and on such reliable mobile infrastructures as Long Term Evolution (LTE). WebRTC is the innovative protocol letting HTML5 compliant browsers to communicate in real-time using a peer-to-peer architecture. LTE on the other hand, is the current...
This paper proposes a new cross-layer based packet scheduling scheme for multimedia traffic in Long Term Evolution (LTE)/LTE Advanced (LTE-A) network. The effective use of the limited resources still remains a major challenge in mobile networks across the globe. A dynamic user scheduling scheme is very important towards actualizing an effective utilization of the limited available resources in LTE/LTE-A...
Mission Critical Communications and Services are of a special nature that needs special requirements. Therefore, there are many challenges that face implementing mission critical communication system over commercial mobile communications networks.

Modern mobile communication increasingly tends to provide high speed transmission multimedia services, therefore the deployment of 4G cellular networks is expected to provide the high speed transmission multimedia services that rely on heterogeneous radio access architectures, whereby cells of different coverage and capacity coexist in the same geographical areas. In this paper, we researched the...
Evolved Multimedia Broadcast Multicast Service (eMBMS) is a point-to-multipoint content delivery solution designed for LTE/LTE-A. It distributes efficiently the broadcast and multicast service to a massive number of mobile devices located in a given geographical area. eMBMS can be used to boost the network's capability for providing high-quality multimedia service in high user-density area such a...
The growing popularity of the high-end mobile computing devices — smartphones, tablets, notebooks and more — equipped with high-speed network access, enables the mobile user to watch multimedia content from any source on any screen, at any time, while on the move or stationary. In this context, the network operators must ensure smooth video streaming with the lowest service delay, jitter, and packet...
Modern cellular networks are expected to support both voice and a growing volume of data traffic. The rapid growth in data traffic has promoted network operators to move to Long Term Evolution (LTE), a 4th generation of wireless network infrastructure. However, LTE architecture does not support native circuit switching services and relies on the IP Multimedia Subsystem (IMS) for supporting voice and...
Trunking communications has been widely applied in dedicated areas for many years, owning to its powerful functionality of scheduling and immediate group communication. Evolution of such services over the cellular mobile network attracts more and more interests due to its wider coverage and cheaper establishment and maintenance cost, especially with the coming era of Long Term Evolution (LTE). In...
Next generation of wireless broadband network such as WiMAX MMR networks and LTE Advanced support high quality multimedia services with high data transmission rate. Most of the current broadband operates at high frequency and thus has limited transmission range. Multi-hop relaying technology is seen as an efficient solution that could enhance coverage and improves system capacity. However, overall...
The Third Generation Partnership Project (3GPP), recently introduced the evolution of the third generation (3G) cellular networks, the Long Term Evolution (LTE) telecommunication system. A key aspect of LTE specifications is the enhancement of Multimedia Broadcast/Multicast Services (MBMS), where the same content is transmitted to multiple users located in a specific service area. A significant point...
In the last few years, we have witnessed an explosion of IP connectivity demand, translated into a rapid development of the corresponding technologies in the wireless access network domain. IP services provision anytime and anywhere becomes very challenging and is seen by the mobile operators as a major opportunity for boosting the average revenue per unit. The further success of IP services deployment...
High quality and sustained multi media experience is expected to be a major feature of the Future Mobile Internet (FMI). Currently deployed novel mobile network technologies such as LTE (Long Term Evolution) make use of the Internet and its best-effort TCP/IP protocol stack to enable applications.
