Title:
EXCHANGE NODE, COMMUNICATION SYSTEM, AND EXCHANGE NODE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2007/066668
Kind Code:
A1
Abstract:
It is possible to provide an exchange node and an exchange node control method
enabling a transmission path search at an absolute position of a call setting
request packet and enabling maintenance management of a safe network. The exchange
node and the exchange node control method includes a position information calculation
unit for receiving radio from a positioning satellite and calculating the local
position and adds the local position information calculated by the position
information calculation unit and an identifier to header information on the
call setting request packet when setting a connection. Moreover, a position
information judgment unit judges whether a combination of position information
on the exchange node nearest to the terminal of the caller recorded in the call
setting request packet header information and the identifier is stored in a storage
unit in advance. A connection control unit receives setting of connection of
a call setting request packet which has been judged to coincide, with a higher
priority.
