Along with the
opening of new generation network for the company of telecommunication and mobile
communication, data business become more and more important. Cell phone is not
only the implement for communication, but also for getting information. So, it
will be the chief business for telecommunication administration to supply the
wireless incremental service. In all kinds of service, because of the mobile
characteristic of cell phone, incremental service related to location will become
the greatest growth point. In order to win the service competition of wireless
internet, the guarantee of critical contents supplying is especially important,
and among these contents, LBS which is a
information service that could tell the location of mobile users is becoming
one of the most important portion.
Firstly, the
paper discussed the technology which is demanded by the Location Based Service,
the technology included: 1st, the kind of location service. 2nd, the precision
of location that different applications needed. 3rd is the location finding
strategy. One of the kernel technologies in LBS service is location
information, and the other is geographic information. They’re complement and
indispensable each other. As a result, we not only get location of the terminal
by platform of location operation, but also converse the value of latitude and
longitude to the geographic information which is cared by user, such as, map,
consequence of path search and so on. In LBS system, those service should be
supplied by GIS: Mapping，Directory, Route, Geocode, Reverse Geocode,
Cogo and Navigation.
Secondly, the
paper introduced the construct of LBS system, which includes: the construct of
hardware, the construct of software, and the characteristic of LBS platform
Finally, the
paper introduced the function which can be accomplished by LBS. Basing on the
location service system, consummate wireless network, geography information
data and information searching engine, the LBS can supply rich location
information service for users, as follows, personal security and succor,
machine’s anti-robbing, group vehicles’ management, dispatch and management of
people and rental equipment, information services that related to location,
flow of material’s management, advertisement, friendship and entertainment
service, etc.
There’re broad
prospect for LBS business, at present, the applications of LBS become more and
more popular. The mobile communication and GIS should be combined to accomplish
the LBS business. We believe that LBS business will be applied broader and
broader along with the constant growing demand and development of GIS in our
country.
