Abstract

A method of communication control, a communication control system, and a recording medium used in the method or system are provided. The method has the steps of recognizing service type information that specifies a type of communication service in a packet with a predetermined protocol; obtaining parameter information for establishing connection, which is previously coordinate to the recognized service type information; and sending a SETUP message that is generated using the obtained parameter information. The communication-control system performs such a method. The recording medium stores a program responsible for executing the method. Accordingly, the present invention ensures the communication band and communication quality on the basis of the types of service and traffic in the TCP/IP application or the UDP/IP application over the Internet.

Claims

1. A method for communication control, comprising the steps of:

recognizing service type information that specifies a type of communication service in a packet with a predetermined protocol;

obtaining parameter information for establishing connection, which is previously coordinate to the recognized service type information; and

sending a SETUP message that is generated using the obtained parameter information.

2. A method for communication control, wherein

the determined protocol is TCP or UDP;

and

the service type information is a terminal port number in a TCP header or UDP header.

3. A method for communication control, comprising the steps of

recognizing traffic type information that specifies a traffic type in a packet with a predetermined protocol;

obtaining parameter information for establishing connection, which is previously coordinate to the recognized service type information; and

sending a SETUP message that is generated using the obtained parameter information.

4. A method for communication control as claimed in

claim 3

, wherein

the predetermined protocol is IP;

and

the traffic type information is a service type or a traffic type in the IP header.

5. A communication control device, comprising:

means for recognizing service type information that specifies a type of communication service in a packet with a predetermined protocol;

means for obtaining parameter information that corresponds to the recognized service type information with reference to a table that defines a coordination between each service type information and a parameter information for establishing a connection; and

means for sending a SETUP message that is generated using the obtained parameter information.

6. A communication control device as claimed in

claim 5

, wherein

the determined protocol is TCP or UDP;

and

the service type information is a terminal port number in a TCP header or UDP header.

7. A communication control device as claimed in

claim 5

or

6

, wherein the table is stored in a network management device external to the communication control device control, and parameter information defined in the table can be obtained by making an access to the network management device.

9. A communication control device as claimed in

claim 7

, wherein

the determined protocol is an IP;

and

the communication quality information is a service type or a traffic type in an IP header.

8. A communication control device, comprising:

means for recognizing traffic type information that specifies a type of traffic in a packet with a predetermined protocol;

means for obtaining parameter information that corresponds to the recognized traffic type information with reference to a table that defines a coordination between each traffic type information and a parameter information for establishing a connection; and

means for sending a SETUP message that is generated using the obtained parameter information.

10. A communication control device as claimed in

claim 8

or

9

, wherein the table is stored in a network management device external to the communication control device control, and parameter information defined in the table can be obtained by making an access to the network management device.

11. A recording medium that stores a computer-readable communication control program for performing a communication control, wherein the communication control program is capable of executing the process comprising the steps of:

recognizing service type information that specifies a type of communication service in a packet with a predetermined protocol;

obtaining parameter information for establishing connection, which is previously coordinate to the recognized service type information; and

sending a SETUP message that is generated using the obtained parameter information.

12. A recording medium that stores a computer-readable communication control program for performing a communication control, wherein the communication control program is capable of executing the process comprising the steps of:

recognizing traffic type information that specifies a traffic type in a packet with a predetermined protocol;

obtaining parameter information for establishing connection, which is previously coordinate to the recognized service type information; and

sending a SETUP message that is generated using the obtained parameter information.

13. A method for communication control, comprising the steps of:

recognizing “

Type of Service”

as a traffic type when a predetermined protocol is IPv4 or recognizing “

Traffic Class”

as a traffic type when a predetermined protocol is IPv6;

recognizing a port number of TCP packet;

grasping information elements of SETUP message corresponding to the traffic type/the port number; and

sending the SETUP message to be generated using the grasped information elements.
