FR2756123A1 - Processing method for open access information carrier system - Google Patents

Abstract

The processing technique involves an initial connection (S1) to a large capacity communications and processing system service network. An image of the service connection is subsequently processed (S2). A connection to an open carrier service is made (S3), with subsequent processing (S4) of a received carrier in the carrier service exchange system. A carrier transmission is processed in the carrier service exchange system, with a cancellation (S6) of the carrier service in the carrier service exchange system. Factoring information is then generated in a subscriber network access sub-system (S7), and finally the connection to the large capacity communications and processing system service network is cancelled (S8).

 Fig. 1 illustrates a construction of a high capacity communication processing system service network according to the present invention. First, the high-capacity communication service system 50, which provides the information retrieval service, serves as a bridge between information providers 80 connected to terminals and a packet-switched network, which are connected to a network. network of users, and it also regularly controls the function in a transit center. When the information user 10 wishes to connect to the high-capacity communication processing system service network 50 via a telephone network 20, packet network 30 or digital integration of services 40 to obtain an information service or a mail service, it implements a subscriber network access subsystem 51 which comprises a subsystem Sia telephone network subsystem, a subsystem packet network access network 51b and a SIc integrated services digital network access subsystem for the function of a call connection.

 The subscriber network access subsystem 51 retrieves the number of the user transmitting the call for a service connection and treats it as a service charge assignment subject for the communication concerned.

 A user connected to subscriber network access subsystem 51 may connect to an information service or mail service as desired.

 The user who wishes to obtain the mail service is openly connected to a packet network service system 55 via a fast switching element (HSSF) 52 and to a central mail service system ( CMSS) 90 through the packet network. The central mail service system 90 receives the information associated with mail processing, provided by a user guidance and service system (GAUSS) 70 by using a real time user query function.

 A local operating and management system (LOMS) 54, which manages the partial apparatus of the high capacity communication processing system service network, is connected to the fast switching element 52 via an operational network access subsystem (ONAS) 53 to manage the expense billing information.

 Fig. 2 is a schematic diagram of the packet network service system, the user guidance and service system, and the central mail service system, illustrating in more detail the system of Fig. 1.

 The packet network service system 100 includes an HSSF processing unit 111 communicating with the fast switching element 52, a service processing unit 112 for call processing, and a communication processing unit. packet 113 connected to the packet network 30.

 The user guidance and service system 130 includes a communication protocol processing unit 131 for processing the packet network communication and the call connection, a user registration unit 132, a communication unit. user identification 133 and a user database 134 which stores information for users.

 Fig. 3 is a flowchart illustrating an example of actual operation according to the method of the present invention. Between the connection S1 and the release S8 of the high-capacity communication processing system service network are the steps of the service connection image processing S2, the S3 service connection, the mail processing. S4 receipt, S5 mail output processing, S6 mail service cancellation and S7 billing information generation.

 As shown in FIG. 4 which is a flowchart of the connection to the service network of the high capacity communication processing system, the information user 10 first presents a request for a subsystem call connection. subscriber network access, by input of "014ex" in Sla.

 If the user connects to the telephone network 20, which varies according to the "014XY" input, it is connected to the telephone network access subsystem Sla.

If it is at the packet network 30, it is connected to the packet network access subsystem 51b and, if the user connects to the ISDN 40 ISDN 40, it is connected to the subsystem of the packet subsystem 51b. 51c integrated services digital network access.

 The subscriber network access subsystem retrieves the user's address number during the call connection and treats the number as a search and billing topic for service charges based on using the accessible accessible service, at a Slb step.

 After completion of the call connection, the user can see the connection picture of the high-capacity communication service system which is chosen according to the type of networks connected, at a step Slc.

When the initial image is displayed, it is determined whether or not a mail has arrived at the address number of the user and the result of the search is sent to the central mail service system 90 in the form of data as indicated in FIG. Table 1, at one stage
Syd.

Upon receipt of the search result provided by the central mail service system 90, the presence of a received mail at a step Sle is determined, and the received mail is transmitted to the user at a step
Slf.

 Fig. 5 is a flowchart illustrating an example of a processing of a service connection image according to the present invention.

When a menu by services is displayed after the connection image of the service network of the high capacity communication processing system at one stage
S2a, a service is selected by the information user 10, at a step S2b.

 Next, it is determined whether or not a mail service is chosen by the user 10, in a step S2c.

If the user 10 has chosen the mail service, it first checks whether the searched user information exists or not, at a step S2d. With the search result of the user information, it is determined whether to connect immediately or not to the central mail service system 90, in a step S2e. This processing is followed by the connection step to the central mail service system.

 If there is no user information, only one information search image is displayed at a step S2f. After this processing, the user identification (ID) and a password are entered at a step S2g.

To confirm the entered information, such as the user identification (ID) and the password, a request for confirmation of the user information is transmitted to the user guidance and service system 70 in the form of data. as indicated in the
Table 3, at a step S2h.

 The user guidance and service system 70, which receives the request for confirmation of the user information, identifies the user information with the database via the user identification unit 133. at a step S2i.

The subscriber network access subsystem is informed of the identification result by the user guidance and service system at a step S2j. Then, the subscriber network access subsystem determines whether the identification is a success or a failure, at a step
S2k.

 If the user information is true, a request is made for a connection to the central mail service system 90 to confirm the connection or not to the mail service at a step S2e.

 If not, the fact related to the desired result is indicated to the user and the menu by services is displayed again, in step S2a.

 Next, it is determined whether or not a connection to the information service is requested at a step S21. If the user requests the information service, the user is connected to the information service at a step S2m and is connected openly to the information provider via the network service system. packets 55 to support the use of the information service at a step S2n.

 After using the information service, it is determined whether or not to cancel the high-capacity communication service at a step S20. If there is no request to cancel or release the high capacity communication service, the service menu is displayed again in step S2a.

 Fig. 6 is a flowchart illustrating an example of a connection to the central mail service system according to the present invention.

 After completion of the identification of the user information, the procedure goes to a call connection to the central mail service system 90, at a step S3a.

With the call connection, subscriber network access subsystem 51 sends the user information, in the form of data as indicated in FIG.
Table 2; at the central mail service system 90, at a step S3b.

From the data format of the user information from the subscriber network access subsystem 51, the central mail service system 90 determines whether it is a usual mail connection.
The in the form of data as shown in Table 4, or a live retrieval of received mail in the form of data as shown in Table 1, at a step S3d.

 In the case of the usual mail connection, the data form of the user information is confirmed at a step S3e and the identification of the user information is determined at S3f. If there is an identity, a mail service connection picture is displayed at a step S3g.

 When the data form is appropriate and the user information is not identified, the call connection is canceled at a step S3h.

In the case of direct retrieval of received mail, the address number is confirmed, at stages
S3i and S3j, and the received mail is retrieved using the user address number as the key value, at a step S3k.

After the live retrieval of the received mail, the result is transmitted to the subscriber network access subsystem in data form indicated in the
Table 2, at a step S31, and the call connection is canceled.

 Fig. 7 is a flowchart illustrating an example of a processing of mail received in the central mail service system according to the present invention.

After confirming the user information, the login image is first displayed at step
S3F. In addition, it is checked whether or not there is a received mail, by means of the user identification (ID), at a step S4a.

 Next, it is determined whether a mail is received at the user identification (ED) connected above at a step S4b. If there is no mail to the user identification (ID), a guidance message is displayed at a step S4c.

 In the case where there is one or more received mails, one displays the mail list, including the titles, at a step S4d.

The user reads the mail list and determines whether or not to request a confirmation of the content of the mail received at a step S4e. If he wants to confirm the content, the desired mail is chosen at one stage
S4f and the selected mail is displayed at a step S4g. The user then determines whether or not he requests a downlink with a transmission protocol, at a step S4h. If it desires a downlink, a menu for the downlink is provided to perform a downlink at a step S4i.

 After this operation, it is confirmed that the recovery of the received mail is completed, at a step S4j. When the recovery is not yet complete, the presence of another received mail is confirmed again until the completion of the recovery, in step S4d.

 Fig. 8 is a flowchart illustrating an example of a processing of a mail transmitted in the central mail service system according to the present invention.

 After completion of the confirmation of the content of the received mail, an image for a mail transmission is displayed at a step S5a.

 If the user does not wish to obtain a mail, after a determination in a step S5b, it is determined whether the mail service must be canceled or not, in a step S5c.

 When the user desires to get up mail, a mail write image is displayed at a step S5d and the mail recipient is entered at a step S5e.

 Next, it is checked whether the information for the recipient of the mail exists or not, at a step S5f.

If the mail recipient information exists, a list of mail editing methods necessary to produce mail is displayed at a step S5g. In the opposite case, the information of the recipient of the mail is confirmed, at a step S5h, and it is determined whether the confirmation is completed or not, at a step S5i. When it is determined that confirmation of the recipient information is performed, the user selects the mail editing method. In the opposite case, it is determined whether to cancel the connection to the mail service.

 In addition to the above method, it is determined whether the mail editing method uses an on-line editor or not, at a step S5j. If the on-line editor is used, a mail-writing function is provided for performing online or live mail editing at a step S5k. If a mail that is produced with a PC is loaded in the upstream direction by a protocol, the upstream transfer protocol is activated at a step S51.

 When it is determined that the writing of the mail is completed at a step S5m, it is confirmed that the edited mail must be transmitted, at a step S5n, to send the mail to the recipient, at a step S50.

 When the transmission of the mail is finished or the information of the recipient of the mail is not requested, it is confirmed that the connection to the mail service will be canceled at a step S5p.

 Fig. 9 is a flowchart illustrating an example of a cancellation of the central mail service system according to the present invention.

When the user requests a cancellation or release of the mail service connection,
transmits an X.25 call cancel request packet to the subscriber network access subsystem 51 at a step S6a.

 The subscriber network access subsystem 51 which has received the X.25 call cancel request packet at a step S6b transmits the X.25 call cancel request packet to the central system mail service to cancel a call at a step S6c.

 Fig. 10 is a flowchart illustrating an example of a generation of billing information in the high capacity communication service system according to the present invention. When the user terminates the mail service, the subscriber network access subsystem 51 receives the information capacity used and the usage time from the mail service connection to the end of the service, in order to use them as a database for the accounting of the charges to be charged to the users specified by each originating subscriber of call, in a step S7a.

 The billing information is generated by summing the calculated basic data and the settlement coefficients at a step S7b.

 The master data and billing information generated in each subscriber network access subsystem is sent to the operational network access subsystem 53 via the fast switching element. The operational network access subsystem 53 transmits the billing information to a local operating and management system 54 via a LAN in a step 57c.

 Fig. 11 is a flowchart illustrating an example of a cancellation of the service network of the high capacity communication processing system according to the present invention.

When the user wishes to cancel the connection to the communication service system after complete generation of the billing information in a step S8a, it is determined whether or not to inspect the billing information generated in real time, at a step
S8b. If the user wishes to inspect the billing information, the information is displayed through a simultaneous billing information output function at a step S8c. Then, the connection to the service network of the high-capacity communication processing system is canceled, at one stage
S8D.

 Otherwise, a service connection image is again displayed at a step S8e.
