Location Services and Mobile Navigation
(1 hour)
Forming part of mpirical’s acclaimed “The Essential Guide to” series, this 1 hour eSeminar introduces the concept of Location Services and Mobile Navigation, explaining the types of services which may be offered, as well as the associated location information required. In addition, the eSeminar examines the location mechanisms used in both GSM and UMTS. In so doing, it introduces the required modification to the network architecture, as well as the implementation of different positional techniques.
Who Should Attend
Network Engineers requiring a concise overview of the techniques and technologies used to support location based services. Non-technical Staff seeking a comprehensive yet understandable synopsis of modern location services.
Synopsis
Divided into 3 sections, the topics covered will include:
Section 1: What Are Location Services? (20 minutes)
The introductory section begins by explaining what is meant by the term “Location Services”. In so doing, it describes the key attributes of the location information, such as positional accuracy, time accuracy and frequency of access. The eSeminar then explorers the techniques and issues of providing location information in both 2G and 3G systems, as well as the privacy issues.
- What are Location Services?
- Location Information - Key attributes.
- Location Services - Privacy issues.
Section 2: Location Service Functions and Operation (20 minutes)
This section identifies the new network elements introduced by the Service Providers in order to support location services. These may include: LMU, SMLC, GMLC and LCS clients. The section then goes on to describe the basic procedures between these elements and how they interact with the 2G / 3G system.
- Location Elements - LMU, SMLC, GMLC, LCS Client.
- Interaction with 2G / 3G networks.
- Basic Signalling - Mobile Originated and Terminated requests.
Section 3: Positioning Methods (20 minutes)
This section begins by identifying the key issues associated with deploying Location Services in GSM and UMTS networks. Following this, alternative techniques associated with mobile navigation will be examined, such as ToA, E-OTD, OTDOA, GPS and A-GPS.
- Time of Arrival -GSM / GPRS positioning.
- E-OTD and OTDOA - GSM and UMTS positioning.
- Use of GPS for positioning.
