Question: How does an SGSN determine whether to use the Lg (MAP-based) or Lgd (Diameter-based) interface when communicating with a GMLC, if it supports both?
Option 1: Based on the UE's LCS Capabilities for GPRS
Option 2: Based on operator configuration
Option 3: Automatically, with preference for Lg for legacy support
Option 4: Dependent on the type of positioning request (e.g., emergency vs. non-emergency)
Explanation: The correct answer is based on the information that whether an SGSN supporting both (Lg or Lgd) interfaces uses Lg or Lgd towards a GMLC is determined by operator configuration, highlighting the role of network operator preferences in shaping interface usage for Location Services (LCS) communication between the SGSN and GMLC. This emphasizes the flexibility and configurability inherent in telecom network operations to accommodate various deployment strategies and requirements.
