GSMA’s IoT Device Connection Efficiency Guidelines underpins Telenor’s latest collaboration

Telenor Connexion, the M2M division of operator Telenor, announced that its collaboration with Telit and Allianz Telematics to optimise IoT performance will be in accordance with the GSMA IoT Device Connection Efficiency Guidelines.

Telenor Connexion revealed that it has been working with Telit, a leading global provider of modules and services, and Allianz Telematics, a developer of telematics solutions for automotive and info-mobility markets.

The companies have been working together in Ericsson’s Radio Testing Laboratory, the first independent testing facility to work with the Guidelines since their release on 13th of October, 2014. The project has since taken a significant step forward, having now implemented a verified solution dubbed ‘Network Friendly Mode’ that optimises the behaviour of devices.

The Guidelines help IoT device and application developers expand the number of devices connecting to mobile networks, whilst preventing service outages and ensuring optimal performance that will ultimately enable the market to scale across a diverse range of sectors including automotive, transportation, utilities and health.

They are also designed to be implemented by many operators and module manufactures, which in turn will be vital in keeping the cost down, so that the cost of connectivity is shared amongst many devices.

Allianz Telematics have already adopted the IoT Device Connection Efficiency Guidelines in their Usage Base Insurance (UBI) solution in order to deliver a future-proof product and an overall customer experience, evidence that the Guidelines are already making a positive impact in the M2M space.

Though the M2M market is still developing, it is nonetheless set for rapid growth and fundamental change. Over the past year, there has been an exponential increase in the number of strategic partnerships and cross-industry collaborations in preparation for the inevitable boom in the market.

Yet these Guidelines are essential in facilitating secure and reliable networks which will constantly have to accommodate the addition of more devices, a dilemma which has until recently, abated confidence in the IoT. The announcement is an early, but significant example of how industry standards can expedite collaboration, help accelerate the growth of the IoT and ultimately unlock new revenue opportunities for a range of companies.

1 Introduction

Introduction

Problem Statement 

The predicted large scale growth of IoT Devices and their associated IoT Device Applications will create major challenges for Mobile Network Operators. One major challenge that Mobile Network Operators must overcome is the risk caused by the mass deployment of inefficient, insecure or defective IoT Devices on the Mobile Network Operators’ networks. When deployed on a mass scale such devices can cause network signalling traffic to increase exponentially which impacts network services for all users of the mobile network. In the worst cases the mass deployment of such IoT Devices can disable a mobile network completely.

Mobile Network Operators have faced similar issues in the past, most recently with the massive growth of smartphones. In this case many smartphone application developers inadvertently created many inefficient applications. Over the past decade Mobile Network Operators, smartphone device makers and smartphone application developers have worked together to resolve these difficulties through a mix of increasing network capacity (e.g. 3.5G and 4G network deployment), 3GPP standardisation, improvements to smartphone operating systems and development of smartphone application developer guidelines. With the forecasted high growth in IoT Devices the industry is in a similar situation to the start of the smartphone boom, but with a different group of device makers and application developers. With the IoT however the potential number of devices is higher and, due to the different commercial models for IoT Devices, it is far more challenging for the Mobile Network Operator to influence the behaviour of IoT Device manufacturers and IoT Device Application developers.

An IoT Device overusing the network may lead to problems such as:

  • Reducing the lifetime of the (U)SIM card by increasing dramatically the read/write cycles.
  • Increased power consumption of the device due to continuous restarts which may also affect the device lifetime.
  • Local issues within the Mobile Network Operator’s network such as cell congestion.
  • Capacity and performance problems within the Mobile Network Operator’s core network, such as signalling storms, which result in wide area network disruption.
  • Negatively impacting the IoT Service’s performance, potentially resulting in delayed communications, degradation of the service quality and even service outages.

IoT Devices overusing the mobile network can affect not only the devices causing the incident but also other devices on the same IoT Service Platform or those devices of other End Customers.

Network signalling resources are dimensioned assuming an overall device usage profile with a sensible balance between traffic and signalling needs. It is therefore important that IoT Devices using mobile networks adhere to some basic principles before they can be safely connected to mobile networks.

Good design is essential to ensure that IoT Device performance is optimized and to prevent failure mechanisms creating runaway situations which may result in network overload. In situations where many IoT Devices of the same type may be deployed on a single mobile network the cumulative effect may have a detrimental impact on overall network performance. Poor design of IoT Device Application to IoT Service Platform communications which disregard the mobile network and IoT Device status may result in inefficient use of network and device resources, affecting the IoT Service experience end-to-end.

Avoiding Chaos – Enabling developers to build efficient IoT devices and applications

In most Internet of Things scenarios IoT device firmware and software play a significant part in determining the overall performance and behavior of the IoT service on the mobile network.
The predicted large scale growth of IoT devices and applications will create major challenges for the IoT ecosystem. One major challenge that the ecosystem must overcome is the risk caused by the mass deployment of inefficient, insecure or defective IoT devices which may lead to serious problems such as:

  • Local issues within the mobile network, such as cell congestion.
  • Capacity and performance problems within the mobile network’s core network, such as signalling storms, which result in wide area disruption.
  • Degradation of IoT service performance, potentially resulting in delayed communications, degradation of the service quality and even complete service outages.
  • Increased power consumption of the IoT devices due to unintelligent communication error handing which may reduce device lifetime.

Mobile network resources are dimensioned assuming a ‘generalised’ device usage profile with a sensible balance between traffic and signalling. It is important that IoT devices using mobile networks adhere to some basic principles before they can be safely connected to mobile networks.

The GSMA has worked with its ecosystem partners to establish the GSMA IoT Device Connection Efficiency Guidelines for how machines should communicate via the mobile network in the most intelligent and efficient way. The connectivity of billions of IoT devices in a scalable network depends on all stakeholders following a common approach, ensuring everyone can enjoy the benefits of efficient connectivity.

The GSMA has also recently published a supplementary IoT Device Connection Efficiency Test Cases document which outlines the test cases that need to be passed by an IoT device in order for it to be considered compliant with the requirements stated within the Connection Efficiency Guidelines.
