Anti-Steering Detection

Anti-Steering of Roaming Detection and Prevention is a key element in a  comprehensive roaming strategy. The increased use of anti-steering methodologies provides a commercial risk for operators attempting to accurately control their roamers. By detecting and thwarting these tactics, you can provide your subscribers with seamless service at the highest quality.

  • Detects anti-steering events down to the signalling message level and counteracts such attempts by visited networks, allowing precision steering of outbound roamers to preferred networks. 
  • Helps you negotiate better deals with roaming partners, reduce revenue leakage, improve subscriber experience, even prevent future anti-steering behavior.

Anti-Steering Types

There are various anti-steering manoeuvres networks may employ: 

  • Direct to HLR – operator sends UL messages to the HLR if steering messages are based on E.214 numbers. 
  • Registration Interference – attempt to retain subscriber by interfering with attach to new (or home) network
  • Registration Resubmission –  rapidly sends UL messages on behalf of the handset to appear as manual selection and bypass steering policy
  • Gateway Location Register (GLR) – denies home network the opportunity to steer by retaining signaling traffic
  • OTA Blocking – retains subscriber by blocking messages from home network which would update subscriber SIM.

Precision Made Easy

All anti-steering events are detected across all access technologies 2G/3G and 4G/LTE. Multi-event detection and reporting allow you detailed evidence as to which networks are deploying anti-steering.

Active filtering can be updated quickly to neutralise any new anti-steering resubmission methods.

Manual blocking is made easy as rules are developed independently of the underlying protocol thus reducing the complex changes required to support roamers on different technologies.

Accessible Reporting

The intuitive GUI allows anyone on your team to be provided proper access levels to customise reports, set alerts, publish reports, and export data to suit their individual needs (no matter their level of technical expertise). 

Equipped with powerful (yet agile) reporting and alerting features, you can be sure to have the most accurate information about your network traffic at your fingertips. 

Easily set alerts or publish reports as broad as outbound traffic or drill down to troubleshoot VIP roaming complaints with the touch of a button.

Signalling Providers and Signalling Hubs

Signalling is your business — at least maintain control. We have provided many Tier 1 signalling hubs with the capability to control and secure their signalling

Compliance

Compliant with GSMA IR.73

GSMA’s Steering of Roaming Implementation Guidelines, IR.73 defines guidelines which provide cooperative requirements between networks when SoR is employed. It also provides technical requirements for minimal impact on the visited network’s SS7 and Diameter links. Version 1.0 was released June 2005, then Versions 2.0 and 3.0 in 2006, and Version 4.0 in October 2014.
