Location-based services (LBS) use location data from mobile devices to provide information services. The document discusses the history and concepts of LBS, how location is determined, applications like weather and traffic updates, and factors for LBS success like compelling applications and privacy protections. Major challenges include positioning technologies, privacy, and interoperability. LBS have many benefits but also risks to privacy if personal location data is misused.

3.  Location-based services (LBS) are a general class of
computer program-level services that use location
data to control features.
 As such LBS is an information service and has a
number of uses in social networking today as an
entertainment service, which is accessible with
mobile devices through the mobile network and
which uses information on the geographical position
of the mobile device.

6.  Emergency Medical Services(EMS)
 Yellow Pages
 Local weather and traffic broadcast in radio and TV
 Emergency phone services

7.  Position
 “32.49’49.7964”-116.49’.9.9228””
 Location
 “San diego downtown gas lamp quarter”
 Location Service(LCS)
 “Where am I?”
 Location Based Service(LBS)
 “How can I go to gas lamp quarter from
here?”

8.  Control plane locating
Sometimes referred to as positioning
 Self-reported positioning
A low cost alternative to using location technology to track the
player, is to not track at all.
this is more commonly known as a user "check-in".
 Others
local-range technologies such as Bluetooth Low Energy, WLAN,
infrared and/or RFID/Near Field Communication technologies
are used to match devices to nearby services.

11.  Compelling applications
• Valuable to consumer and businesses
• Easy and intuitive to use
• Good return on the investment
 Handset availability
• Wide range of LBS-capable handsets

12.  Internet-friendly
• IP based user plane standards
 Good business model
• Custom segmentation is important
• Adopt applications from 3rd parties
• Help operators increase revenue
 User awareness and promotion
• Security and privacy concerns

13.  Positioning technologies
 Privacy
 Interoperability
 Emergency services

14.  It could do harm to the user’s privacy
 There is consumer's concerns about potential
threats to personal security and use of personal
location records for commercial purposes and
legal actions.
 Preventing unauthorized access to personal
location information is a prerequisite to protect
privacy.

15.  Location-based services are transforming the
ways people across the country conduct
business, organize their lives, and have fun. They
can save time, money, and even lives.
 As both the potential and the challenges of LBS
have become more understood, the Commission,
has begun to assess ways to best ensure the LBS
users enjoy all their benefits and that their
confidential information is secure.
