Stochastic user behaviour modelling and network simulation for resource management in cooperation with mobile telecommunications and broadcast networks

Abstract

Abstract:The latest generations of telecommunications networks have been designed to deliver higher data rates than widely used second generation telecommunications networks, providing flexible communication capabilities that can deliver high quality video images. However, these new generations of telecommunications networks are interference limited, impairing their performance in cases of heavy traffic and high usage. This limits the services offered by a telecommunications network operator to those that the operator is confident their network can meet the demand for. One way to lift this constraint would be for the mobile telecommunications network operator to obtain the cooperation of a broadcast network operator so that during periods when the demand for the service is too high for the telecommunications network to meet, the service can be transferred to the broadcast network. In the United Kingdom the most recent telecommunications networks on the market are third generation UMTS networks while the terrestrial digital broadcast networks are DVB-T networks. This paper proposes a way for UMTS network operators to forecast the traffic associated with high demand services intended to be deployed on the UMTS network and when demand requires to transfer it to a cooperating DVB-T network. The paper aims to justify to UMTS network operators the use of a DVB-T network as a support for a UMTS network by clearly showing how using a DVB-T network to support it can increase the revenue generated by their network.

Intersystem Soft Handover for Converged DVB-H and UMTS Networks

“…Reference [12] proposed a way for the UMTS network operators to forecast the traffic of the high-demand services and transfer them to a cooperating DVB-T network when appropriate. However, no detailed procedures of transferring the DVB-T traffic to UMTS are described.…”

“…While [5]- [8] focus on how the intersystem handover is actually performed between either UMTS and GSM or UMTS and WLANs, [9]- [12] focus on the radio resource optimization between the broadcast and the telecommunications networks. Furthermore, all the aforementioned works did not consider the tradeoff between the network operation cost and the network QoS, and no quantization of such parameters is available.…”

Maximizing Transmission Opportunities in Wireless Multihop Networks

“…However, most of previous works on mobility models do not consider any explicit rationale behind the mobility behaviour. In other words, a node does not make a move without referring to a certain demand for the move (Oppenheim, 1995;Centonza et al, 2006). In the context of RWP, the selection of a waypoint is random within a given terrain area and does not take a certain behavioural rule or rationale into consideration.…”

A QoS Monitoring System in a Heterogeneous Multi-Domain DVB-H Platform

“…A QoS Monitoring System in a Heterogeneous Multi-Domain DVB-H Platform I. INTRODUCTION T HE vision of cooperation between MPEG-2 broadcasting and IP-based mobile data communication networks is rapidly becoming a reality [3], [4]. Many commercial mobile TV networks are likely to be hybrid networks combining a uni-directional broadcast network with a bi-directional mobile telecommunications network.…”

“…The situation can be even worse when the sender and the receiver of the service contents are far apart. This situation implies the presence of a number of IP domains along the service route resulting in a higher probability of network congestion and performance degradation [3], [4], [14].…”
