A navigation system utilizing a paging channel of a mobile communication service
for a navigation apparatus including a mobile communication function is disclosed,
which comprises: a BSC-based traffic server for periodically extracting/synthesizing
traffic information in an area of a BSC, and then transmitting the traffic information
of a peripheral area including the BSC; and a BSC for inserting the traffic information
received from the BSC-based traffic server into the paging channel for a mobile
communication terminal, and then transmitting it. In the navigation system, traffic
conditions information in a corresponding area is transmitted by means of a paging
channel, thereby utilizing real time traffic information while maintaining the
architecture of the existing mobile communication network without an additional
apparatus and communication cost.
