Mobile Operators have experienced a growth of demand of new services with strict requirements and features which imposes challenges to operate the mobile wireless network. 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...
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...
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...
Long Term Evolution (LTE) is considered to be the natural evolution for the current Global System for Mobile Communications-Railways (GSM-R) in high speed railway environments, not only for its technical advantages and increased performance, but also due to the current evolution of public communication systems. In railway environments, mission critical services, operation assistance services, 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...
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. The orientation towards TCP/IP is logical due to the success of the Internet. However, TCP/IP still provides...
This paper deals with increasing requirements for network intelligence (NI) and the technologies that generate it. NI is the basis for applying policy and differentiating charging capabilities, which are driven by the need to monetise the record growth of mobile broadband data. Nl is gathered by various techniques from evolving network functions, LTE (long term evolution) and IMS (IP multimedia subsystem)...
