Description

  The present invention relates to a service management method, a service search method, a service management search system, and a storage medium storing a program between information devices such as personal computers connected via a network.

  TCP / IP (Transmission) is used between information terminal devices such as personal computers (hereinafter referred to as “PCs”) and PDAs (Personal Digital Assistance) and peripheral devices such as printers, scanners, and digital still cameras connected via a network. Communication can be performed by establishing a connection using a Control Protocol / Internet Protocol) protocol. However, the connection cannot be established unless the address information of the counterpart device is known when performing communication.

  If the fixed address information of the communication destination device is acquired, the connection can be easily established. For example, in an environment in which dynamic address information is acquired from a DHCP (Dynamic Host Configuration Protocol) server, the address Since the information changes every time the information is activated, it is difficult for the devices to establish communication via the network. There is also a method of searching for the partner device by relying on the host name, but there is no guarantee that the partner device is registered in the DNS (Domain Name Server) server, or a name other than that registered in the DNS server. May be arbitrarily named by the user. In such a case, a search from the host name registered in the DNS server is not reliable. There are other methods for resolving the host name, such as a method that relies on an identification name based on NetBIOS (Network Basic Input Output System) or a method that searches from a WINS (Windows (registered trademark) Internet Name Service) server. As in the case of DNS, acquisition of valid address information fails if the counterpart device is not properly set. Further, even if valid address information of the counterpart device is retrieved from DNS or the like, there is a problem that it is not known whether the counterpart device can provide a desired service.

  There is a method called port scan as one of means for checking whether or not a partner device can provide a desired service. A packet is transmitted by designating a port number, and whether or not the port is open is confirmed by a response. When searching for a partner device by relying on port scanning without knowing the partner's address, there is a problem in that communication efficiency is poor because scanning is performed for a certain range of IP addresses. In addition, since it is possible to obtain only information on whether the IP address and the designated port are open, it is not possible to confirm whether different types of application programs are running on the same port.

Therefore, there is a service search technique as a method for solving such a problem. As service search technologies, for example, Jini, SLP (Service Location Protocol), and UPnP (Universal Plug and Play) are known. In these service search technologies, in the case of an embedded device, it is necessary to create a firmware for the device in accordance with the standard, and there is a problem that the service cannot be found unless it conforms to the standard. In the case of an information terminal device such as a PC, automatic registration of services cannot be performed unless an application program is created in accordance with these standards, and the user needs to register manually. If you do not register manually, the service remains undiscoverable. Further, even if a partner device is found using these conventional service search technologies, if the application program does not correspond to these standards, the user has to manually enter a network address into the application program. Therefore, it can be seen that existing programs need to be operated almost manually. For this reason, an Internet service providing system in which executable macro commands are registered in a server is known (for example, see Patent Document 1). In addition, an information communication system is known in which a received network address is transmitted to a remote control type remote control device, and the remote control device can transmit a reception address to an information processing device (for example, Patent Document 2). reference).

  However, the Internet service providing system disclosed in Patent Document 1 can only support a Web browser type client / server application in which a macro command is executed on the server side and a result screen is returned to the client. There is a problem that the application on the PC cannot be supported. Furthermore, when the information communication system disclosed in Patent Document 2 is operated by a normal PC, a system for receiving a network address from a remote control device and setting the address as a connection destination is required for a PC application. Special devices such as remote control devices are unnecessary. In addition, there is a problem that it is impossible to register in advance what operation is performed after searching for each application.

  The present invention has been made in order to solve the above-described problems, and provides a service management method, a service search method, and a service management method capable of managing and / or searching for services available via the Internet with a simple operation.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 shows a server terminal 1 for providing a service via a communication line 3 and a server terminal 1 via a communication line 3 in which a program of the service management method according to the first embodiment of the present invention is executed. 1 shows a network system composed of a user terminal 2 that communicates and receives a service from a server terminal 1. The server terminal 1 is a PC used in a conference room or the like that functions as an FTP (File Transfer Protocol) server, for example. The user terminal 2 executes FTP client software, for example, and supplies materials prepared by itself to the server terminal 1. It may be a notebook PC that can upload or download necessary materials from the server terminal 1 for browsing. Each PC includes a storage device including a ROM, a RAM, a hard disk, and the like for storing programs, and a central processing unit (hereinafter referred to as “CPU”) that executes various programs and realizes processing of various programs. Yes. Further, the server terminal 1 activates SA (Service Agent) module software of SLP (Service Location Protocol), which is one of the existing service search technologies, and the user terminal 2 is a UA (User Agent) which is an SLP search client. ) Is activated and the service search is performed from the user terminal 2, the server terminal 1 can respond to information on the registered service according to the SLP protocol, and activate the SA module. When the server terminal 1 is requested to search for a service from the user terminal 2 that has installed the UA, the server terminal 1 reads a service information recording file in which the current service information is recorded and responds. This service information recording file name is, for example, “service.txt”.

  The server terminal 1 uses the service management method program according to the first embodiment of the present invention (hereinafter referred to as “service management program”) to manage service information related to services that can be provided by the server terminal 1. When the occurrence of a system event is detected in the process, the system event monitoring process for monitoring the system event in the server terminal 1, and the system event monitoring process, the service information management process provides a service for the service that can generate the generated system event. A process of updating information is executed.

  The server terminal 1 has a communication port for opening and closing the communication line 3, and the server terminal 1 provides a service through the opened communication port. The system event monitored in the system event monitoring step is For example, the server terminal 1 may be in a state where the service can be provided, that is, in a standby state, such as opening / closing of a communication port and a change in the process of an application program.

  With reference to FIG. 2, the operation of the server terminal 1 that executes the service management program by monitoring the opening and closing of the communication port in the system event monitoring step will be described.

  First, the service management program is activated (step S101), and a service information recording file “service.txt” in which service information relating to services that can be currently provided by the server terminal 1 is recorded is generated. For example, it is assumed that three services have already started and ports have been opened, and information on these three services has already been recorded as service information in the service information recording file “service.txt” in step S101. Next, the opening and closing of the communication port is monitored (step S102). The service management program constantly monitors the communication port of the PC during startup. When it is detected that the communication port has been opened, the application that has opened the port is examined, and the application name, protocol, and port number are written in the service information record file “service.txt”.

  If, in step S102, for example, a file transfer server program named OurFTPServer that uses FTP to communicate using FTP port 21 is started in addition to the three services already recorded, the service management program 21 When the port number is opened, the service information recording file “service.txt” is filled with the following information (step S104).

Number: 4; Program: OurFTPServer; Protocol: FTP; Port: 21
This means that the server terminal 1 can provide a communication service using FTP, that is, is in a standby state.

  In step S102, for example, when the service management program detects that the 21st port is closed, it is considered that the program called OurFTPServer has ended, and information regarding the port is deleted from the service information recording file “service.txt” ( Step S103). This means that the server terminal 1 cannot provide a communication service using FTP.

  The system event monitored in the system event monitoring step may be a change in the process of the application program instead of opening / closing the communication port.

  With reference to FIG. 3, the operation of the server terminal 1 that executes the service management program by monitoring the start and end of a program capable of generating a service in the system event monitoring step will be described.

  First, a service management program is started (step S201), a service information recording file “service.txt” that records service information related to services that can be provided by the server terminal 1 is generated, and a program that can generate services is registered. The For example, assume that a file transfer server program named OurFTPServer is registered. Next, activation and termination of the registered program are monitored (step S202). The service management program constantly monitors changes in application processes during startup. When the activation or termination of the program is detected, it is determined whether or not the program is a registered program. If the program whose activation or termination has been detected is a registered program, the service information change is written to the service information record file “service.txt”.

  If, for example, a program called OurFTPServer is started in step S202, since OurFTPServer is a registered program, the information is entered in the service information recording file “service.txt” (step S204). This means that the server terminal 1 can provide a communication service using FTP, that is, is in a standby state.

  When it is detected in step S202 that the program called OurFTPServer has ended, since the information related to the program is deleted from the service information recording file “service.txt” because OurFTPServer is a registered program (step S203). ). This means that the server terminal 1 cannot provide a communication service using FTP.

  As described above, the service management method according to the first embodiment of the present invention can update service information in real time. Therefore, when a service search is performed from the user terminal 2, the latest service information is always obtained. This eliminates the need for manual registration, and makes it possible to manage and / or search for services available via the Internet with a simple operation.

  In the above description, SLP SA module software is used as a service search technique. However, the present invention is not limited to this, and other applications such as UPnP, Jini, and Salutation may be implemented. It is clear.

  Further, as shown in FIG. 3, the service management method according to the first embodiment of the present invention further detects whether or not to disclose the service in advance for each service, or detects the occurrence of a system event. It may have a condition (hereinafter referred to as “policy”) for setting whether or not to disclose as a service that can be provided, and a step of registering this policy for each service may be added.

  With reference to FIG. 4, the operation of the server terminal 1 that executes a service management program using a policy will be described.

  First, a service management program is started (step S301), a service information recording file “service.txt” that records service information related to services that can be provided by the server terminal 1 and a service that can be disclosed as to whether or not the service can be provided. A registered policy management file, for example, “regservice.txt” is generated. Next, a system event is monitored (step S302). As described above, the system event monitored here may be a program that can open and close a port and generate a service. When the occurrence of a system event that terminates the service is detected in step S302, information about the service that can generate the system event is deleted from the service information recording file “service.txt” (step S303). When the occurrence of the system event is detected in step S302, it is determined whether or not a service that can provide the system event in which the occurrence is detected is registered in the policy management file “regservice.txt” (step S304). ).

  If it is determined in step S304 that a service that can provide a system event whose occurrence has been detected is registered in the policy management file “regservice.txt”, the contents registered in the policy management file “regservice.txt” Is publicly available or not publicly available (step S305). If the information can be disclosed, the service information is recorded in the service information recording file “service.txt” (step S306). If the information cannot be disclosed, the service information is recorded in the service information recording file “service.txt”. Absent.

  If it is determined in step S304 that a service that can provide the generated system event is not registered in the policy management file, the user may be asked to open the service and select a policy. Good.

  Referring to FIG. 4, the operation of server terminal 1 that executes a service management program having a policy when it is determined that a service that can provide the generated system event is not registered in the policy management file will be described. To do.

  If it is determined that the service that can provide the system event generated in step S304 is not registered in the policy management file, for example, a dialog shown in FIG. 5 is displayed on the desktop, and the user selects an operation. When the user chooses to publish, the service management information “regservice.txt” registers the service identification information and publishable / unpublishable (step S307). In step S305, it is determined whether or not the contents registered in the policy management file “regservice.txt” can be disclosed. If the contents can be disclosed, the service information recording file “service.txt” is serviced. If the information is recorded (step S306) and cannot be disclosed, the service information is not recorded in the service information recording file “service.txt”.

  Also, as shown in FIG. 5, without registering the policy, this time it is allowed to register as a service, and this dialog will be displayed again at the next startup so that the user can select what to do with the policy. It may be. Similarly, policy registration may not be performed, and it may be possible to select not to register as a service this time.

  In addition, in the policy management file “regservice.txt”, a service that can be disclosed as to whether or not it can be provided is registered. Information on whether or not the server terminal 1 can be provided is included in this information. May be added. That is, the services that can be provided by the server terminal may be limited based on the service information recorded in the policy management file.

  In the above description, for ease of understanding, the server terminal 1 has been described as a single PC. However, a plurality of server terminals 1 may be provided, as long as the server terminal 1 has the functions described above and the like. It is clear that it may be an information device.

  For example, when there are a plurality of server terminals that execute the program of the service management method of the first embodiment and the user terminal 2 searches for a desired service with respect to a plurality of server terminals, the user terminal 2 If each server terminal is in the same subnet, it can broadcast or send a message requesting a service search to a designated multicast address and wait for a response. The server terminal that can provide the requested service returns the service information that can be provided to the user terminal 2 together with the address information. However, in a network environment in which server terminals that provide services are arranged in subnets and broadcasting and multicasting beyond the subnets cannot be performed, it may not be possible to search for a desired service.

  As shown in FIG. 6, a service management terminal 5 that centrally manages service information that can communicate with the server terminal 1 and the user terminal 2 via the communication line 3 in the network may be used. The service management terminal 5 starts SLP DA (Directory Agent) module software, the server terminal 1 registers service information in the service management terminal 5, and the user terminal 2 manages service information in a centralized manner. A service search for 5 is performed. By doing in this way, it becomes possible to perform a service search more efficiently than requesting a plurality of server terminals 1 to perform a service search using broadcast or multicast. In particular, the effect becomes more prominent as the scale of the network is larger and the number of server terminals is larger. Further, the problem of the network environment in which server terminals providing services are arranged in the subnet and broadcasting and multicasting beyond the subnet cannot be performed is also solved.

  With reference to FIG. 7, the operations of the server terminal 1 and the service management terminal 5 that execute a service management program that manages service information using the service management terminal 5 that centrally manages service information will be described.

  First, a service management program is started (step S401), and a service information recording file “service.txt” that records service information related to services that can be provided by the server terminal 1 and a service that can be disclosed as to whether or not the service can be provided. A registered policy management file, for example, “regservice.txt” is generated. In addition, a service management information file “masterservice.txt” in which service information managed by the service management terminal 5 is recorded is generated. The processing from step S302 to step S307 is the same as that in the flowchart of FIG.

In step S303, information related to a service that can generate the system event is deleted from the service information recording file “service.txt”, or service information is recorded in the service information recording file “service.txt” in step S306. And whether to use the service management terminal 5 (steps S402 and S404 ). When the service information is used, the service information updated from the server terminal 1 is transmitted to the service management terminal 5 via the communication line 3, and when the service management terminal receives the updated service information, the service information is deleted ( In step S403) or added (step S405 ), the service management information file “masterservice.txt” in which the service information managed by itself is recorded is updated.

  The service information recorded in the service management information file “masterservice.txt” includes a server terminal that provides the service, a program that can generate the service, identification information of a communication port that provides the service, such as an IP address, a host name, The service application name, protocol name, and port number are recorded as a set. Therefore, the user terminal 2 is provided with a server terminal that provides a service for service information managed by the service management terminal 5, a program that can generate the service, and a service to the service management terminal 5 via the communication line 3. Search information based on at least one communication port identification information, for example, an IP address, a host name, a service application name, a protocol name, and a port number. Reply.

  Further, it is determined whether or not the service management terminal 5 is available. If the service management terminal 5 is unavailable, a message requesting a service search is transmitted to each server terminal by broadcasting or multicasting. be able to.

  With reference to FIG. 8, it is determined whether or not the service management terminal 5 is available. If the service management terminal 5 is unavailable, the user terminal 2 requesting the server to search for a service is requested. The operation will be described.

  First, broadcast transmission is performed, and a message requesting a service search is transmitted to the service management terminal 5 (step S501). When the service management terminal 5 is not found (step S502), broadcast transmission is performed, and a message requesting service search is transmitted to the server terminal 1 (step S503). When the server terminal 1 is found (step S504), the server terminal 1 is requested to transmit service information related to the service searched by unicast (step S505). Also, when the service management terminal 5 is found in step S502 (step S502), the service management terminal 5 is requested to transmit service information related to the service searched by unicast (step S505).

  Furthermore, the service management terminal 5 is inadvertently notified of the presence of the service from the other information device by responding only to the response from the designated IP address in response to the search from the other information device. It may not be possible. Specifically, the process executed by the service management terminal 5 for centrally managing service information further includes an identification information registration process for registering identification information of the user terminal 2, for example, an IP address, and the user terminal 2 When the information search request is transmitted to the service management terminal 5 together with the identification information of the user terminal 2, it is determined whether or not the identification information of the user terminal 2 is registered in the identification information registration step with respect to the received search request. You may have a process and the process of permitting the search of the service information which self manages when it is judged that the identification information of the user terminal 2 is registered by the identification information registration process.

For example, a user terminal 2 that is permitted to use a device having an IP address in the range of 11.22.33.1 to 11.22.33.255, a device having an IP address of 22.33.44.5, a device in the same subnet to which the user terminal 2 belongs In this case, in the identification information registration process executed by the service management terminal 5, registration is performed as follows.
Number: 4; Program: OurFTPServer; Protocol: FTP; Port: 21; Permit: 11.22.33. *; 22.33.44.5; 255.255.255.255
Based on this condition, the service management terminal 5 responds to a service search request from the user terminal.

  As described above, the service management method according to the first embodiment of the present invention can update service information in real time. Therefore, when a service search is performed from the user terminal 2, the latest service information is always obtained. This eliminates the need for manual registration, and makes it possible to manage and / or search for services available via the Internet with a simple operation. In addition, if a service management terminal that centrally manages service information is used, it is possible to perform service search more efficiently than requesting service search to a plurality of server terminals using broadcast or multicast. Become. In particular, the effect becomes more prominent as the scale of the network is larger and the number of server terminals is larger.

(Second Embodiment)
With reference to FIG. 9, the operation of the terminal that executes the service search program according to the second embodiment of the present invention will be described. Since the environment in which the terminal operates is the same as that of the network system of FIG. 1 described in the first embodiment, description thereof is omitted.

  First, a service management program is activated (step S601), and a service in which service information relating to a service that can be provided by the current server terminal and service management information registered in association with identification information of the user terminal 2 that uses the service is recorded. A management information file such as “masterservice.txt” is generated. In the service management information file “masterservice.txt”, for example, the name of the client program executed by the user terminal 2, the execution path of the program, the protocol, and the port number are registered in association with the service information. By specifying the program, it is possible to search using the protocol and port number registered in association with each other as a search condition. When a service search request based on a predetermined condition is received from the user terminal 2, a corresponding client program is selected (step S602), and a predetermined service search condition is read (step S603). Here, the predetermined condition may be any one or more of a client program program name executed by the user terminal 2, a program execution path, a protocol, a port number, and the like. The example of the screen displayed when the user terminal 2 inputs the search condition of a service is shown. FIG. 10 is an example of a search program screen showing a program for generating a service. From this screen, it is possible to search for services by specifying the name of the program or to register a new client program. FIG. 11 shows an example of a detailed setting screen for setting details of registered contents. From this screen, the program name, protocol, port number, program execution path can be registered, and a desired service can be searched using the protocol, port number, etc. as search conditions.

  Next, a service search is performed in the service management information file “masterservice.txt” (step S604). When a desired service is found (step S605), it is notified that the service has been found (step S606). If not found (step S605), it is notified that the service could not be found (step S607).

  The system event monitoring program for executing the system event monitoring process for monitoring the system event described in the first embodiment may be combined so that a desired service can be searched in real time. Furthermore, the execution path of the program can be registered in advance, and the client program can be activated after discovery of the service device.

  With reference to FIG. 12, the operation of a terminal that executes a service search program combined with a system event monitoring program will be described. Here, it is assumed that the service management program has already been started and a plurality of service processing procedures are registered in advance in step S601 in the service management information file “masterservice.txt”.

  A system event monitoring program is started (step S701), and system events are monitored (step S702). As described above, the system event monitored here may be a program that can open and close a port and generate a service. When the occurrence of a system event for terminating the service is detected in step S702, the monitoring program detects the start of the program registered to search for the service, and a search execution selection dialog screen is displayed (step S703). The user is inquired whether to search for a service (step S704). An example of the search execution selection dialog screen displayed in step S703 is shown in FIG. When the user designates a service search, a service search is performed based on the port number or protocol registered in association with the activated program (step S705). The service search may use a service search module such as SLP UA. When a desired service is found, the service is executed according to the processing procedure recorded in the service management information file “masterservice.txt” (step S707).

  By registering the operation after the search in advance, the operation from the service search to the connection to the service of the client program can be made smooth. A program having an existing communication function can connect to the connection destination specified at the time of startup by specifying the network address of the connection destination as an argument. As a service processing procedure, for example, the network address of the connection destination may be registered in the service management information file “masterservice.txt” as follows.

MyProgram.exe / connect 11.22.33.44; MyClientProg.exe -host tarou-pc
Thus, by specifying an argument for each program and specifying to start the client program, the user's operation can be simplified. In addition, the client program does not need to conform to a specific service search protocol.

  For programs that cannot specify the network address of the connection destination, it is necessary to connect manually. In normal programs, a dialog box containing an edit box for entering the connection destination is displayed, and the connection is displayed in the edit box. It becomes necessary to input the previous IP address or the like.

  In the service search method according to the present invention, at the time of service search, the address of the partner device is automatically recorded in a shared memory called a clipboard, and the information stored here is used from any application running on the OS. Can be easily copied and used. For programs that cannot be started using a command line argument that specifies the connection destination, register the network address of the service providing device to the clipboard, and manually enter the IP address of the connection destination. This eliminates the need for cumbersome operations such as driving in and increases convenience.

  For example, it is assumed that a list of client programs can be managed on a screen as shown in FIG. Accordingly, it is assumed that a screen for designating an operation after finding a service of a program, for example, an operation selection screen shown in FIG. An example of pre-registering operations on this screen will be described.

In the case of a program called MyFtp, register the obtained IP address as [IP_ADDR] to execute the following command.
C: \ Program Files \ MyFtp \ MyFtp.exe / connect [IP_ADDR]
In the case of a Java (registered trademark) program called MyMsg, register the acquired IP address as [IP_ADDR] and the port number as [PORT] to execute the following command.
java (registered trademark) D: \ MyMsg \ MyMsg.java (registered trademark) HOST [IP_ADDR] PORT [PORT]
In the case of a program called MyChat, register the obtained IP address as [IP_ADDR] to execute the following command.
E: \ MyChat \ MyChat.exe [IP_ADDR]
In the case of a program called groupservice, register the acquired IP address as [IP_ADDR] to execute the following command.
E: \ Program \ GroupSoft \ groupservice.exe -add [IP_ADDR]
In the case of an application that cannot be started by specifying the destination with the command line argument, register to execute "Copy IP Address to Clipboard", start the application, and the IP address copied to the clipboard in the connection dialog Paste and connect.

  With reference to FIG. 14, an operation of executing a service search program for registering a service processing procedure in the service management information file “masterservice.txt” for a service whose operation after the search is not registered will be described. Here, in the process following step S707 in which the service is found in the flowchart of FIG. 12, the above-described registration is recorded in the service management information file “masterservice.txt”, and the FTP client program called MyFTP is notified of the service. What you are searching for. Furthermore, as shown in the screen of FIG. 15, a list of devices (server terminals) that provide services is displayed. Assume that one of them, for example, a PC named “server1” is designated as a connection destination desired by the user as shown in the screen of FIG. It is determined whether or not the operation is registered in the service management information file “masterservice.txt” (step S801). If it is determined that the operation is not registered, for example, the operation is registered on the operation registration screen of FIG. If it is determined that the operation is registered (step S802), the registered operation is confirmed (step S803), and the registered operation is executed (step S804, step S805).

An example in which the registered operation is command execution will be described.
C: \ Program Files \ MyFtp \ MyFtp.exe / connect [IP_ADDR]
If the command is registered, the IP address of the specified device is 11.22.33.44, so the command C: \ Program Files \ MyFtp \ MyFtp.exe / connect 11.22.33.44 is executed to automatically start and connect the program. Done in

  Also, if the action to copy the address to the clipboard is registered, the character string "11.22.33.44" is copied to the clipboard, so the user calls the connection function of the client program and edit box to specify the connection destination In addition, operations such as pasting the IP address copied to the clipboard are performed.

  In this way, by registering in advance to perform a service search for a program that communicates with information devices such as other PCs, the port number, protocol, etc. required for the service search module are registered. By setting the information, it is possible to search for the service of the communication partner of the activated client program in a short time.

  As described above, in the service management method according to the second embodiment of the present invention, if the user specifies a program that the user wants to use, the search program automatically determines and searches the search condition. You can search for devices that provide the desired service without knowledge of service search and communication protocols, eliminating the need for manual registration and providing services that can be used via the Internet with simple operations. It becomes possible to manage and / or search.

(Third embodiment)
In the above description, the service management method and the service search method according to the present invention are separately executed. However, the service management method and the service search method according to the present invention can be executed by the same terminal. . For example, for a program registered as a program that can generate a service on a single terminal, the service is automatically managed for the activation of the program, while for the activation of the program registered as a client, You can also search for services.

  When one program is a program that can function as both a program that can generate a service and a client, such as IP Messenger, which is one of instant messenger software, it waits for a connection from the other party as a service, or the other party as a client The user may be inquired about whether to perform a search for connection. Alternatively, registration as a service may be automatically performed, and the user may be inquired only about whether or not to perform a search as a client.

  FIG. 19 is a block diagram illustrating the configuration of a service management and search system according to the third embodiment of the present invention. This service management and search system can be realized by a single PC in which a program for executing the above service management method and service search method is installed. Check if the process monitoring program is resident and registered as a service or client.

  When activation or termination of a process of a program registered as a service is detected, the service information is updated to the latest one. When the service management terminal is available, the service information update is notified to the server terminal, and the service information registered for the service management terminal is also updated. On the other hand, when the activation or termination of a process of a program registered as a client is detected, a service search using a user terminal can be performed according to the registered service search condition. As a result of the search, when a service is found on a desired device, an operation registered in advance is executed. For example, a command set according to the specifications of the client program is executed. Alternatively, by automatically copying the IP address obtained as a result of the search to the clipboard, the user can paste the IP address into the connection dialog of the client software by pressing the Ctrl + V key, and immediately connect to the network.

  In the above description, examples of system events monitored in the service monitoring process include opening / closing of communication ports, changes in application program processes, etc., but the present invention is not limited to this, and results As long as the server terminal can be provided with a service, that is, it can be anything as long as it can reach a standby state.

  As described above, since the service management and search system according to the third embodiment of the present invention can update service information in real time, the search program automatically searches if the user specifies a program to be used. Since the conditions are determined and searched, even if the user does not have knowledge about service search or communication protocol, it is always possible to search for a device that provides a desired service and search for a service from a user terminal. The latest service information can be provided even on a single PC, for example, and there is no need for manual registration, and it is possible to manage and / or search for services available via the Internet with a simple operation. become.

  It can be applied to applications such as service management and service search between information devices connected via a network, enabling connection at an application level with a simple operation and using an existing application as it is.
