– Network Simulation can Play a Crucial Role in Addressing Excess Signalling Traffic and its Impact on Network Performance
With huge growth in smartphone and tablet adoption, the mobile industry is looking for ways to manage the growing signalling burden created by ‘chatty’ smart devices. A new White Paper from Anite, the global leader in wireless device testing, argues that solutions used to simulate the network behaviour in the lab will play an increasing role in addressing such signalling issues before smart devices reach the market.
"Many mobile network operators have received unwelcome negative publicity as a result of issues related with the use of smartphones. Some of these issues are caused by the inefficient signalling behaviour of smart devices that effectively keep connecting to and disconnecting from the mobile network in order to prolong battery life. This "switching on and off" increases signalling between the device and the network, and is exacerbated by "chatty" applications such as email and social networking apps that demand constant updates from the network."
According to network operators, signalling may use as much as 60% of an operator’s network resources. With only 40% remaining for traffic, the inefficiency of smart devices could erode operators’ data revenues. Consumers also suffer, with connection and battery life issues, and such inefficiencies can substantially degrade user experience.
The White Paper highlights the need for an eco-system driven approach as the best way to address the signalling overload challenge. Mobile devices and applications should now be developed with a greater awareness of their impact on network performance. While field tests and network management systems can help operators understand how the behaviour of new devices affects the network, such approaches are costly and reactive. The greater use of pre-launch laboratory tests will help reduce costs and minimise the occurrence of problems after a product has been launched. Dr Stavropoulos explains:
"We believe that network simulation solutions, which are already widely used for device interoperability testing, will play a crucial role in ensuring that smart devices do not have an adverse impact on the mobile network. Anite is increasingly working with mobile network operators to deploy these solutions and measure the signalling performance of devices and applications in the lab. Ultimately, we expect such network simulation based tests to become part of many operators’ device acceptance schemes."
