GMLC – Gateway Mobile Location Center (Open Source Version)

Introduction to PAiCore Technologies GMLC

The Gateway Mobile Location Centre empowers telecom operators to offer efficient and highly accurate Location-Based Services (LBS) for mobile subscribers roaming across either legacy GSM or UMTS/HSPA+ networks, or Next Generation Networks like LTE/LTE-Advanced/LTE-Advanced Pro and 5G NR, without relying on smartphone apps or an internet connection.

The GMLC is the first node an external LBS client accesses in a mobile core network. The GMLC may request routing and/or location information from the HLR/HSS (Home Location Register/Home Subscriber Server) or MSC/VLR (Mobile Switching Centre/Visitor Location Register) or SGSN (Serving GPRS Support Node) or MME (Mobility Management Entity). Furthermore, in conjunction with a Serving Mobile Location Center (SMLC) or Evolved-SMLC, it may receive mobile subscriber and/or IoT devices periodic or event based deferred location reports. The GMLC serves as the secure gateway between external applications and mobile network location data, while the SMLC and/or E-SMLC carry out user equipment location estimates using radio measurements from nearby base stations.

These capabilities are essential for a wide range of scenarios, including:

• Emergency location tracking
• Context-aware targeted messaging
• Network-based analytics
• Regulatory compliance and public safety services
• Lawful interception
