Abstract

Universal Mobile Telecommunications System networks will be based on the Internet Protocol (IP) to provide an efficient support for applications with bursty traffic characteristics, e.g. WWW browsers. Such IP-based networks must include Quality of Service (QoS) mechanisms to enable the usage of real-time applications, such as mobile telephony. Different network services are necessary to satisfy the different needs of applications in wireless mobile networks. To overcome this problem, this article proposes the Mobile Differentiated Services QoS Model (MoDiQ), a framework to provide QoS in wireless mobile networks. MoDiQ is based on the Differentiated Services approach, developed by the Internet Engineering Task Force for wireline networks. An important part of MoDiQ is the MoDiQ service model, which comprises separate services for mobile terminals and non-mobile terminals. This can enhance the efficiency of resource utilization in scenarios where not all mobile terminals are actually moving.
