When subscribers stay or travel near country borders, there may be areas where neighboring country networks have stronger coverage, causing the handsets to accidentally roam to their networks.
Many subscribers, unaware of this registration, may stay with the foreign network for quite some time, resulting in high international rates/tariffs for both incoming and outgoing calls and SMSs, as well as loss of revenue to the home network operator.
The Starhome® Intelligent Border Roaming™ solution combines control over all registration attempts of near border roaming roamers with interrogation of HPMN elements. Intelligent Border Roaming* analyzes the sequence of roaming events to identify accidental registration to foreign visitor location registers (VLRs) near the border.
* USA patent.
