For MNOs or IoT network providers, badly configured connected devices can cause a signaling storm in an operator’s network as well as drain its own battery. Network performance degrades the signaling storm and in extreme cases might lead to a network blackout. A drained battery is a critical aspect for some IoT SP’s.

The normal approach would be to expand the network capacity to cater to the increased demand for connectivity. However, this approach is not sustainable because the ARPU from IoT connectivity is lower and does not allow for expansion, creating the need for a robust solution to allow sustainable growth in IoT.

The Network Safeguard Solution relieves network congestion caused by the repeated authentication of IoT devices and contributes to device power consumption saving. It is implemented using a Java application (Network Safeguard Application) in the SIM card and an application server (Network Safeguard Server) to manage & control it. This is deployable within an existing subscriber base.

Network Safeguard Solution features include:

  • Read/Change Configuration
  • Device Back-off
  • Device agnostic
  • Network agnostic (2G/3G/4G, home/roaming)
  • SIM card agnostic
  • Device Management (as option)
  • Campaign Management
  • Reporting

Network Safeguard comes with two distinct components:

  1. Network Safeguard Application (Java applet) and
  2. Network Safeguard Server (SolvEx).

The Network Safeguard Application manages:

  • Network attachment status of IoT devices.
  • Automatic device identification.
  • Connection scheduling.

It provides real time information for:

  • Network/Subscriber monitoring.
  • Terminal behavior analysis.

The Network Safeguard Server is required to:

  • Deploy the Network Safeguard Application in SIM cards.
  • Manage lifecycle of the applet (Grouping, Profiling, back-off, etc.).
  • Activation/De-activation of applets.
  • Configuration of back-off schema in SIM Files.
  • Monitor and Report device and application status.

Network attachment management also:

  1. Guarantees trigger parameters are stored in a file on the SIM card [configurable from Server using OTA-SMS].
  2. Monitor device behavior against trigger parameters.
  3. When back-off is activated, the device is detached from the network for a period calculated using back-off time.
  4. After the back-off period has elapsed, Network Safeguard Application allows the SIM to authenticate with network and usual device behavior is logged.

As part of Valid’s OTA Connectivity Suite services, the Network Safeguard relies on it for common framework features including provisioning, reporting, etc.

Main benefits of this solution includes:

  • Network congestion relief.
  • Increased battery time.
  • Precise implementation of “Back-off” schemes.
  • Prioritizing of high ARPU subscribers.
  • Control and monitor network.
  • Permanent disconnection of SIMs that are in ‘aggressive’ devices.
