OsmoSMLC

OsmoSMLC is the Osmocom Serving Mobile Location Centre. It implements the SMLC functionality
as specified in 3GPP networks Location_Services architecture.

Functionality

  • Location Methods
    • currently only the Timing Advance based method of determining a mobile station.
      • operator must configure the locations of the cells in the osmo-smlc configuration file
  • 3GPP Lb (BSC-SMLC) interface using BSSAP-LE on top of connection-oriented SCCP and M3UA/SCTP/IP

If you run a network based on OsmoBSC and OsmoSMLC, the serving MSC (such as OsmoMSC can subsequently issue PERFORM LOCATION REQUEST queries on the A interface. The BSC will work with the SMLC to obtain the position, and return a PERFORM LOCATION RESPONSE back to the inquiring serving MSC.
