2. Description of the Related Art A client /
A conventional service system constructed on a distributed system of server systems will be described first with reference to FIG. The service is a general service such as, for example, an order receiving service, a delivery service, a collection service, a membership registration service, or a search service. A service related to a business is mainly used as an example.

FIG. 7 shows a conventional service system 700.
PC 710 and client PC 73
FIG. 4 shows a simplified block diagram of how a service between 0 and 0 is executed. The server PC 710 mainly has a service providing unit 720 in which a program for executing this service is stored. Client PC 730
Mainly has a service using unit 740 for connecting to the service providing unit 720 of the server PC 710 to perform a service execution request and a service reference process.
The service provision processing unit 720 includes the service generation processing unit 72
2. Service execution processing unit 724 and communication control unit 72
6. The service use unit 740
Service connection processing unit 742, service call processing unit 74
4 and a communication control unit 746.

Prior to the use of the service, the client PC 730 uses the service connection processing unit 742 to determine whether or not the server PC 710 is available and whether or not the communication infrastructure built in the server PC 710 is available. A check signal for confirming this is transmitted to server PC 710 via communication control unit 746. This corresponds to the processing step S701 in FIG. When this check signal is received by server PC 710, service generation processing section 722 returns service reference information to client PC 730 via communication control section 726. After that, the client PC 730 uses the service reference information to
A request signal for using the service is sent to the server P
Send to C710. This is the processing step S70 in FIG.
It corresponds to 2. This request signal is sent to the server PC 710.
Is received by the service execution processing unit 724, the service is executed, and the execution result of the service after the execution is returned to the client PC 730.

[0005] As described above, the client / server system is composed of a server system that provides a service and a client system that is a communication terminal that uses the service. A communication control unit called a communication infrastructure mediates between the client system and the server system. When the client system issues a request signal, the communication infrastructure of the client system converts the request signal into a communicable format and sends it to the communication infrastructure of the server system. The communication infrastructure of the server system converts the request received from the communication infrastructure of the client system into the original format, and passes the request to the service.

[0006] Here, the technology of the communication infrastructure built on the distributed system used for the client / server system includes Remote Procedure Calli.
ng (hereinafter referred to as RPC), distributed object infrastructure, and the like are known.

[0007] In a system using RPC, a server system prepares a port mapper which is a reception port for enabling a request from a client system to be received, and receives a request from the client system. Alternatively, the server system is activated as a daemon process, and the daemon process receives a request transmitted by a specific port number to the server computer on which the daemon process runs.

In a system using the distributed object platform, a server system registers a service name set by a system administrator and a generated service reference to a name resolution service that acquires a service reference using the service name as a key. . The client system specifies a service name for the name resolution service, acquires a service reference, and issues a request for the service reference. For RPC, refer to “Power Program
Amming with RPC "(John Bloo
by Mer, ISBN 0-937175-77-3, F
eb. 1992) and the like, for the distributed object platform, refer to “The Common Object Request Request”.

and Specification, Revisi
on 2.3 "(Object Management)
Group, Jun. 1999).

[0009]

In the client / server system, for example, individual services among services such as an order receiving service, a delivery service, and a collection service which constitute a sales service system,
The order receiving service is provided by using RPC, the delivery service is provided by using RPC and the distributed object base, and the collection service is provided by using the distributed object base. Sometimes.

[0010] In such a case, when using the order receiving service of the sales service system, the client side determines the type of communication infrastructure of the server PC corresponding to the desired order receiving service, the type of service provided by each server PC, the desired order receiving. It was necessary to keep track of the location (IP address, etc.) of the server PC with the service on the network.

An object of the present invention is to provide a client / server system using a plurality of types of communication platforms in order to solve the above-mentioned problems, to facilitate the connection process and efficiently use a service requested to be used. An object of the present invention is to provide a service system and a service method for searching and a processing program therefor.

[0012]

In order to achieve the above object, in a service system according to the present invention, a service system is constructed based on a plurality of types of communication platforms and received from a communication terminal connected via a communication line. At least one service providing means for providing a service in response to a use request, a service identifier transmitted from the communication terminal at the time of the service use request, for identifying a specific service among the services, and a communication infrastructure on which the service is constructed A communication control identifier for identifying a service providing means for providing a service is searched for reference information indicating a position on the network based on the received information. Service search means for transmitting to the terminal. As described above, in the service system according to the present invention, the service providing unit constructed using a plurality of types of communication platforms is managed by the service search unit that searches using the service identifier and the communication control identifier. Thus, the client can use the service only by inquiring of the service search unit without knowing the location on the network of the server PC that provides the desired service. Further, in this way, when the arrangement and number of server PCs and the type of communication infrastructure used by the service providing unit are changed, it is not necessary to change the settings on the client PC side when using the service system. , The troublesomeness can be eliminated.

The communication control unit is read into the main storage unit 206 (step S403). Next, the service search processing unit 222 causes the service generation processing unit 213 to execute based on the service notification parameter (step S404).

The service generation processing unit 213 acquires reference information of the requested service based on the previously detected system information, and returns it to the service search processing unit 222 (step S405). The service reference information is address information of the same or another server PC connected to the same network and storing the desired service. The service search processing unit 222 returns the service reference information to the client PC 104 (Step S406).

The user who has requested the use of the service can make an execution request to the service execution processing unit 214 using the obtained service reference information (step S407). When an execution request is made, various information associated with the service is called up from a storage device (not shown) in the server PC 102 in which system information is stored, and is returned to the client PC 104.

When the use of the service is terminated, a service termination request is input from the client PC 104 by inputting the parameter at the time of the service update as shown in an input example 600 shown in FIG. , The service deletion processing unit 223 is executed.

As described above, in the service system according to the present invention, a service providing unit constructed using a plurality of types of communication platforms is managed by a service search unit that searches using a service identifier and a communication control identifier. . Thus, the client can use the service only by inquiring of the service search unit without knowing the location on the network of the server PC that provides the desired service. Further, in this way, when the arrangement and number of server PCs and the type of communication infrastructure used by the service providing unit are changed, it is not necessary to change the settings on the client PC side when using the service system. ,
