AI Technical Summary

Benefits of technology

This solution enables immediate and cost-effective provisioning of communication services by efficiently utilizing existing network resources, reducing the need for frequent contract renegotiations and ensuring reliable communication paths even in case of network failures.

Problems solved by technology

In the conventional technique, therefore, it takes time to make a new contract with a telecommunication company or a communication service provider, so that various communication services requested by the user cannot be immediately provided.
According to the conventional techniques, communication services which are becoming various more and more in future require a significant capital investment, so that it is uneconomical to telecommunication companies.

second embodiment

[0110] In the invention, a combination of a plurality of communication services offered by different telecommunication companies is shared by a plurality of users. When communication service of the telecommunication company “c” indicated by the entry 102c and communication service of the telecommunication company “d” shown in the entry 102d in FIG. 4 are combined, for example, a communication path of total 5 Mbps is available in the area between Tokyo and Osaka. Therefore, when communication service requests of 4 Mbps and 1 Mbps (total 5 Mbps) are issued from the users B and C in the area between Tokyo and Osaka as shown by entries 103b and 103c in FIG. 5, if the users B and C agree to share the communication paths of the telecommunication companies 'b” and “c”, the bandwidths required by the users B and C are assured.

[0111] Entries 104b and 104c in FIG. 6 show an example of network control information generated in correspondence with the users B and C. Transmission packets of the u...

third embodiment

[0112] In the invention, by combining a plurality of communication paths of different service terms, a communication service request of a user or a plurality of users requiring a long service term is satisfied.

[0113] For example, as shown by an entry 103d in FIG. 5, when the user D desires communication service of the bandwidth of 1 Mbps in the term from Sep. 1st, 2001 to Aug. 31st, 2003 and the request of the user is satisfied by combining communication services of the telecommunication companies “e” and “f” as shown by entries 102e and 102f in FIG. 4, the assistant server generates the network control information indicated by entries 104d and 104D shown in FIG. 6. In this case, the user D performs communication with the branch office by using the communication network of the telecommunication company “e” in the term from Sep. 1st, 2001 to Aug. 31st, 2002 and using the communication network of the telecommunication company “f” in the term from Sep. 1st, 2002 to Aug. 31st, 2003.

fourth embodiment

[0116] In the invention, two communication paths each satisfying required bandwidth are assigned to one user. One of the communication paths is used as a working path and the other one is used as a backup path. When a failure occurs in the working communication path, the working communication path is switched to the backup communication path.

[0117] For example, as shown by an entry 103e in FIG. 5, when a service request from the user E indicates the necessity of a backup line, the processor 100 of the assistant node searches the supply information database 102 for two supply information entries satisfying the service request from the user E. When supply information indicated by, for example, the entries 102g and 102h in FIG. 4 is retrieved in response to the request, the processor 100 generates network control information indicated by the entries 104e and 104E in FIG. 6 and transmits the network control information to the network controller 32.

[0118] In this case, first node contro...

Abstract

In a communication network having a communication node connected to a plurality of service providers' networks, a network controller connected to the communication node, and a server for supplying network control information to the network controller, the server stores definition information of communication services provided by the service providers. When a service request specifying a communication path to be assured is received from the user terminal, the server retrieves communication service definition information matched with the service request and notifies the search result to the user terminal. In response to a notification of agreement from the user terminal, the server transmits network control information for setting a communication path to the network controller and the network controller supplies communication path control information generated on the basis of the network control information to the communication node.

Description

[0001] The present application is a continuation of application Ser. No. 09 / 943,511, filed Aug. 31, 2001, the contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] (1) Field of the Invention [0003] The present invention relates to an assistant server and a path connection control method for a telecommunication company's network or a service provider's network. More particularly, the invention relates to an assistant server and a path connection control method for receiving a communication service request from a user terminal and connecting the user terminal to a communication path which matches the request in a communication network constructed by a plurality of communication service networks. [0004] (2) Description of the Related Art [0005] In recent years, with the rapid spread of the Internet and the emergence of various network applications of E-mail and the like, a network user has come to be able to perform various works such as a settlement...
