attribute is more distinguishing and valuable to mobile network operators and
their constituents (customers, suppliers, and investors) than customer location
information. Location-based Services (LBS) are predicted to finally take off
beginning in late 2005 to early 2006. Many people do not understand the
underlying technologies necessary to position mobile cellular phones in GSM
networks. This publication provides the user with an easy to understand,
presentation that includes detailed notes (Notes View of PPT document) to
facilitate understanding of mobile positioning systems for GSM. The publication
includes illustrations of standard GSM architectures including the GMLC, SMLC,
and LMU and discussion of positioning
functionalities.
Target Audience for this Publication
- Anyone desiring more illustrations and
description of GSM positioning architectures and
functions
- Anyone tasked with understanding and/or
teaching GSM positioning
Note: This publication will be especially useful for those people interested
in GSM positioning technologies and procedures. For those people
also interested in GIS and location management, we recommend Mobile
Positioning and Location Management publication. Mind Commerce also offers the full, on-site training course
