VoIP Switch - Concern: Growing Number of Mobile Users Could Increase IoT Failure Rate

June 30, 2014


According to an analysis of the issue at Telecom Tech, the use of mobile devices is set to increase through 2018 – so much so that it could hinder the uptime of future Internet of things (IoT) applications.

The tech news site points out that recent research from IDATE, a telecommunications research and analysis company, says the number of mobile users could reach eight billion by 2019, so over the span of the next five years, the number of mobile users could increase as much as 21 percent. This comes in addition to the growth of fixed Internet users, Telecom Tech says, that will also increase in the coming years; between 2013 and 2018, analysts predict that this market segment will grow by 18 percent.

Other research by network solutions provider Cellwize compounds the issue by stating that mobile operators could see a failure rate of IoT applications as high as 30 percent because of network congestion. This is not simply a result of increase mobile device usage as it relates to handheld devices such as smartphones and tablets. The number of IoT devices may also increase – an expected 26 billion units globally by 2020, says Cellwize – and this could create a disastrous chain of device failures due to overwhelming load on 3G and 2G networks.

The 3G-based cellular networks can inherently hold and deliver more bandwidth than the legacy 2G. However, when 3G networks become overloaded, mobile carriers often fall back to 2G, and if 2G cannot hold 3G's displaced load, then customers may drop calls and have their service disrupted while IoT applications witness failure across the board.

This is the biggest challenge the IoT is facing with regard to load handling: the switch to 3G or better. Faster, more advanced networks can deal with large amounts of traffic better than legacy systems. Although mobile providers are trying to place customers on 4G, statistics show that, by 2018, 4G will only make up about two-thirds of the world's cellular traffic. Analysis shows that 4G will pass 3G, and therefore 2G will fall even farther by the wayside, but the growing number of mobile users and IoT devices could outpace network transitions to newer technologies.

Intro to Basic System Features

Accounts Overview
An account is a logical entity usually representing some logical or physical end point in the VoIP network.

Customers are logical entities in the system for which invoices will be generated. They may be termination partners, resellers of a service, or a virtual .

Tariffs and Rates
Tariff is logical entity in the system, which represents rules for rating and billing calls made by Account or Customer to which this Tariff has been assigned.

Balance and Credit Limit
In addition to Tariff, each Customer or Account, except Root Customer, has those two basic rating/billing parameters associated with it – Balance and Credit Limit.

Intro to Advanced System Features

On-Net Routing
On-Net Routing is the feature that allows placing calls from one account in the system to another account in the system.

Ability to Charging On-Net (Account-to-Account) Calls
In some cases it might be necessary to charge either caller or callee or both for the on-net call based on per-minute rate.

Automatic Database Backup
The Softswitch includes the system which allows performing automatic backup of the database periodically.

Ability to Get exchange rate using external script
Exchange rates can be set using external custom script.
