Solving timeout issues for mobile phones

Solving timeout issues for mobile phones

Overloaded cellphone networks and untraced emergency calls from mobile phones could soon be a thing of the past, thanks to research being carried out at AUT University.

Professor Nik Kasabov and Professor Steve MacDonell from AUT have joined MediaLab, Telecom, Lucent and two other New Zealand universities to look into mobile communications issues including location determination, network optimisation and customer relationship management (CRM).

Professor Kasabov says the work being done with Lucent is leveraging AUT’s research expertise to develop and test innovative computational methods and tools which can be applied to improve mobile network performance.

“We focus on the problems of predicting mobile calls traffic density at any geographical location, for minutes, hours and weeks ahead, and on identifying new consumer network usage patterns,” he says.

“Having access to large volumes of data will enable us to further explore aspects of both customer and traffic behaviour in relation to network activity and to the provision of new mobile services.” The research topics build on two groundbreaking Lucent Bell Laboratories technologies, Dynamic Optimisation and Per Call Measurement Data (PCMD). Lucent has been performing Dynamic Optimisation research in conjunction with Telecom NZ since 2004. The research project involves a continuous cycle of New Zealand-based testing and analysis, which is fed to the US for further analysis and interpretation at Bell Laboratories in New Jersey. It is then fed back to the New Zealand team for more testing and enhancement.

“Dynamic Optimisation gives mobile network operators a whole new way to manage the traffic on their network,” says Lucent New Zealand general manager Jonathan van Smit. “It allows the network to respond dynamically to changes in when and where people are using the network. For example, when there’s a big rugby game or a traffic jam, there are a large number of people using their mobiles in a concentrated area. Until now, mobile networks haven’t coped very well with this.

With Dynamic Optimisation, we can ‘borrow’ unused capacity from areas where it isn’t currently needed and redirect it to areas of high use. It’s a completely new approach that results in fewer dropped calls and better service for customers.”
