Serving Mobile Location Centre (SMLC)

The Mobile Arts Serving Mobile Location Centre (SMLC) can be used in all GSM, UMTS and CDMA networks. The SMLC provides both network-based, terminal-based, probe-based and hybrid location methods to provide reliable, accurate location and presence information to applications.

Location Methods

The location methods supported by the SMLC include:

  • 3GPP GSM LCS Location (SMLC-part)
    • BSSAP-signalling with BSC
    • GSM Enhanced Cell-Id Location (CGI + TA + NMR)
    • GSM Control Plane A-GPS Location (MS-based, MS-assisted) and reference data import from local/external A-GPS reference data server
    • GSM Cell Location Data import
  • 3GPP UMTS LCS Location (SMLC-part)
    • PCAP-signalling with RNC
    • UMTS Cell-Id Location (Cell-Id + RTT)
    • UMTS A-GPS Location (MS-based, MS-assisted)
    • UMTS Cell Location Data import
  • Probe-Based location

Features

The Mobile Arts SMLC provides an extensive set of features, such as:

  • High resolution location calculation, including support for Enhanced CGI based location using advanced methods, such as particle filtering (using maps), Kalman filtering (stochastic location estimation) and self-tuning (neural network)
  • Zone-based and proximity-based event triggered location reporting
  • Location of mobile terminals in both active and passive state
