Congestion control method and system
First Claim
1. A congestion control method for a network comprising:
- a mobile user terminal located in a mobile network;
a contents server for providing a contents service in the Internet; and
a GW (gateway) server used as a repeater in the case where access is made from the mobile network to the Internet, wherein association identifiers for identifying, as the flow of a series of services, screen informations ranging from information in a service top menu to supply information in contemplated service are imparted to respective screen informations in a tree structure constituting a web service provided by the contents server, and upon the occurrence of congestion, priority connection control of the service being in connection is performed based on the association identifiers, the association identifiers are constituted respectively by identifiers representing “
start,”
“
continue,” and
“
end,”
upon the occurrence of congest ion in the GW server, the GW server judges the association identifier contained in the screen information to be relayed, and for a request for the connection of a service provided with an association identifier representing “
continue,”
the relay of the transfer of service information is continued until an association identifier representing “
end”
appears, while for a request for the connection of a service provided with an association identifier representing “
start,”
the connection is cut off.

Abstract
Association identifiers for identifying, as the flow of a series of services, screen information are imparted to respective screen informations in a tree structure constituting a web service provided by the contents server. The association identifiers are constituted respectively by an identifier “start” representing a start screen of a series of service elements, an identifier “continue” representing a screen located along the way to contemplated information, and an identifier “end” representing a screen of the final contemplated information. When a congested state has occurred in the GW server during operation, the GW server judges the association identifier contained in screen information to be relayed. In this case, for screen information which is in the state of continuation for the series of service elements and, at the same time, the association identifier represents “continue,” the relay of the transfer of service information is continued until an association identifier representing “end” appears. On the other hand, for a request for the connection of a new service provided with an association identifier representing “start,” the connection is cut off. The above construction can prevent the cut-off of connection during utilization of service and thus can contribute to improved service to users.

5. A congestion control system for a network comprising:
-
a mobile user terminal located in a mobile network;
a contents server for providing a contents service in the Internet; and
a GW (gateway) server used as a relay device in access from the mobile network to the Internet, whereinassociation identifiers for performing the priority connection control of a service being in connection upon the occurrence of congestion are imparted respectively to screens of a tree structure constituting a web service provided by the contents server, the GW server has the function of judging the association identifiers, contained in the screen information, as a series of service elements and the function of performing the priority connection control of a service being in connection upon the occurrence of congestion in the GW server, wherein, the association identifiers are constituted respectively by identifiers representing “
start,”
“
continue,” and
“
end,” and
upon the occurrence of congestion, for a request for the connection of a service provided with an association identifier representing “
continue,”
the means for performing the priority connection control of a service being in connection continues the transfer of service information until an association identifier representing “
end”
appears, while for a request for the connection of a service provided with an association identifier representing “
start,”
the means for performing the priority connection control of a service on connection cuts off the connection. - View Dependent Claims (7)
