LCS – Location Services Service description Stage 1

(P) GSM Rel-98 v7.3.0    2001/04    23 p.

Rapporteur:  DEOL, Amar
Descendant:  TS 22.071    
See also:  LCS-related TS/TR    

This TS provides the Stage One description of Location Services (LCS) on Global System for Mobile communications (GSM) networks. A Stage One description provides an overall service description, primarily from the service subscriber's and user's points of view, but not dealing with the details of the Man Machine Interface (MMI). This GTS includes information applicable to network operators, service providers and terminal, base station system, switch and data base manufacturers.

  • Location Services may be considered as a network provided enabling technology consisting of standardized service capabilities which enables the provision of location applications. This application may be service provider specific. The description of the numerous and varied possible location applications which are enabled by this technology are outside the scope of this TS. However, clarifying examples of how the functionality being specified may be used to provide specific location services is included in various sections of the specification.
This TS contains the core requirements for the LCS on GSM to an extent sufficient to derive a complete definition of the LCS at the service level. However, this TS also documents some additional requirements which may suggest in a non-normative manner certain ways the system may be implemented to support the LCS feature.
