Description

  The present invention relates to a remote connection technique in which a client computer remotely connected to a server computer executes an application program on the server computer using a virtual desktop environment generated on the server computer, and in particular, a user requests a remote connection. The present invention relates to a remote connection technology capable of extremely shortening the time from when the virtual desktop environment is made available until the virtual desktop environment becomes available.

  In recent years, a terminal service in which a client computer is remotely connected to a server computer and an application program is executed on the server computer using a virtual desktop environment generated on the server computer has been used ( For example, see Patent Literature 1 and Non-Patent Literature 1).

  The server computer providing the terminal service sends information on the virtual desktop screen to the client computer, and the client computer sends commands and data to the server computer in accordance with an operation performed by the user on the virtual desktop screen. In the server computer, the application program is executed according to the command and data sent from the client computer, and the execution result is sent to the client computer. The client computer displays the execution result sent from the server computer on the virtual desktop screen.

  Thus, in the terminal service, the application program is executed only on the server computer. It is also possible to simultaneously connect to a server computer from a plurality of client computers and execute an application program. In this case, a session is divided for each user (client computer), and each user has a separate virtual desktop. Execute application programs using the environment.

  As described above, in the terminal service, even when there are a plurality of client computers, the application program is executed on the server computer, so that the management (installation, version upgrade, etc.) of the application program is facilitated and low Even a spec client computer can perform high-load processing at high speed.

  FIG. 9 is a block diagram showing an example of the configuration of a conventional remote connection system that implements a terminal service, and includes a server computer 100 and a plurality of client computers 200-1 to 200-k.

  On the server computer 100, an operating system 102 including a terminal service providing unit 103 is operating. The terminal service providing unit 103 is realized by a program called a terminal server, for example. On the server computer 100, virtual desktop environments 101-2 to 101-k for the client computers 200-2 to 200-k that are remotely connected have already been generated. Further, an authentication information storage unit 300 is connected to the server computer 100, and the authentication information storage unit 300 stores user IDs and passwords of users U1 to Uk of the client computers 200-1 to 200-k. Has been.

  Each of the client computers 200-1 to 200-k includes terminal service using units 201-1 to 201-k for using a terminal service, and input units 202-1 to 202-k such as a keyboard and an LCD or the like. Display units 203-1 to 203-k are connected. The terminal service using units 201-1 to 201-k are realized by, for example, a program called remote desktop connection (RDC) or a program called terminal service client (TSC).

  The conventional remote connection system having such a configuration operates as follows. Now, for example, it is assumed that the user U1 of the client computer 200-1 uses the terminal service provided by the server computer 100.

  The user U1 first inputs his / her user ID and password from the input unit 202-1, and then instructs transmission of a remote connection request. Thereby, as shown in the flowchart of FIG. 10, the client computer 200-1 transmits a remote connection request including the user ID and password of the user U1 to the server computer 100 (step S101).

  When a remote connection request is sent from the client computer 200-1, the operating system 102 in the server computer 100 receives the user ID and password included therein and the authentication information registered in the authentication information storage unit 300. An authentication process based on the above is performed (step S102).

  In the case of authentication NG, the operating system 102 sends an error notification to the client computer 200-1. On the other hand, in the case of authentication OK, the terminal service utilization unit 103 in the operating system 102 generates a virtual desktop environment 101-1 for the client computer 200-1 (step S103). The virtual desktop environment 101-1 for the client computer 200-1 is an environment for executing an application program on the server computer 100 in accordance with commands and data transmitted from the client computer 200-1. In order to generate the virtual desktop environment 101-1, processing for securing an area for the client computer 200-1 on the main memory (processing that consumes system resources), and predetermined information in the secured area. A writing process is performed.

  Thereafter, the terminal service providing unit 103 transmits a virtual desktop screen to the client computer 200-1 (step S104).

  The terminal service utilization unit 201-1 in the client computer 200-1 displays the virtual desktop screen transmitted from the server computer 100 on the display unit 203-1 (step S105). Thereafter, the terminal service using unit 201-1 transmits commands and data to the server computer 100 in accordance with an operation performed on the virtual desktop screen by the user U1 (step S106).

  The terminal service providing unit 103 in the server computer 100 executes the application program using the virtual desktop environment 101-1 according to the command and data sent from the client computer 200-1, and the execution result is sent to the client computer 200-. 1 (steps S107 and S108).

  The terminal service utilization unit 201-1 in the client computer 200-1 displays the execution result on the virtual desktop screen (step S109). Thereafter, every time the user U1 performs an operation on the virtual desktop screen, the same processes as those in steps S106 to S109 described above are performed.

  When ending the use of the terminal service, the user U1 uses the input unit 202-1 to instruct the end of the use of the terminal service. Thereby, the client computer 200-1 transmits a termination request to the server computer 100 (step S110).

As a result, the terminal service providing unit 103 in the server computer 100 disconnects the session with the client computer 200-1 and releases resources used to generate the virtual desktop environment 101-1. Step S111).

  The conventional remote connection system described above generates a virtual desktop environment after a remote connection request is sent from a client computer, and the generation process of the virtual desktop environment takes a considerable load. There was a problem that it took a considerable amount of time before a user could use a virtual desktop environment after making a remote connection request. In particular, this problem becomes prominent when a plurality of client computers simultaneously request remote connection.

  In order to solve such a problem, for example, the virtual desktop environment generated when the first remote connection request is received from the user U1 is left as a disconnected session even after the end request is received from the user U1. If there is a remote connection request from the same user U1 again, a method of making the virtual desktop environment left as a disconnected session an active session can be considered. According to this method, since it is not necessary to generate a virtual desktop environment for the second and subsequent remote connection requests, the user U1 can immediately use the virtual desktop environment. However, since this method always has a virtual desktop environment as a disconnected session, there is a problem that the resources of the server computer are wasted.

[Action]
A server computer that provides a terminal service to the client computer generates a virtual desktop environment for the client computer at a predetermined start time for the client computer. Note that the activation time can be, for example, a time that is a predetermined time before the work start time of the user of the client computer. Thereafter, for example, when the user's business start time is reached and a remote connection request is sent from the client computer, the server computer connects the client computer and the server computer, and the generated virtual desktop environment is Make it available from the client computer.

  When the user of the client computer ends the use of the terminal service, the client computer sends an end request to the server computer. The user transmits the above-described termination request, for example, at his / her business end time. When a termination request is sent from the client computer, the server computer disconnects the connection between the client computer and its own server computer. Thereafter, when the end time predetermined for the client computer is reached, the server computer releases resources consumed by the virtual desktop environment for the client computer. Note that the end time can be, for example, a time after a predetermined time from the user's work end time.

  According to the present invention, it becomes possible for a user of a client computer to immediately execute an application program using a virtual desktop environment after a remote connection request without wasting resources of the server computer.

  The reason why the user of the client computer can immediately execute the application program using the virtual desktop environment after the remote connection request is that the server computer is started at a predetermined start time for the client computer. This is because the computer generates a virtual desktop environment for the client computer. The reason why the remote of the server computer is not consumed wastefully is to release the resources consumed by the virtual desktop environment for the client computer when the predetermined end time is reached for the client computer. Because it is.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration example of an embodiment of a remote connection system according to the present invention. Referring to the figure, the remote connection system of the present embodiment includes a server computer 1 that provides a terminal service, a plurality of client computers 2-1 to 2-k that use the terminal service, and each client computer 2- Management server 3 that transmits a remote connection request or termination request to server computer 1 according to schedule information of users U1 to Uk of 1-2k, and a storage device that is accessible from both server computer 1 and management server 3 4 is included.

  The storage device 4 is realized by a magnetic disk device or the like, and includes an authentication information storage unit 41, a schedule management unit 42, and a virtual desktop environment management table 43.

  In the authentication information storage unit 41, user IDs and passwords of the users U1 to Uk are registered. In the present embodiment, it is assumed that the user IDs of the users U1 to Uk are “id1 to idk” and the passwords are “p1 to pk”.

  In the schedule management unit 42, schedule information of each user U1 to Uk is registered. The schedule information includes the user ID of the user, the start time that is the time for generating the virtual desktop environment for the user, and the end that is the time to end (disappear) the virtual desktop environment for the user And time. FIG. 2 is a diagram illustrating a content example of the schedule management unit 42. The first line of the figure shows that the user U1 with the user ID “id1” has an activation time of “7:00” and an end time of “18:00”.

  In the virtual desktop environment management table 43, management information for managing the virtual desktop environment generated on the server computer 1 is registered. Management information exists for each generated virtual desktop environment, and each management information is a session between a user ID of a user who uses the virtual desktop environment and a client computer which uses the virtual desktop environment. Includes status information indicating whether or not is disconnected, and resource information indicating resources consumed by the virtual desktop environment. FIG. 3 is a diagram showing an example of the contents of the virtual desktop environment management table 43. The first line of the figure shows that the virtual desktop environment for the user U1 with the user ID “id1” is generated on the server computer 1, but the client computer 2-1 used by the user U1. And the server computer 1 are disconnected (disconnected session). In the second line, the virtual desktop environment for the user U2 having the user ID “id2” is generated on the server computer 1, and the client computer 2-2 used by the user U2 is used. And the server computer 1 are connected (active session).

  The operating system 12 on the server computer 1 includes a terminal service providing unit 13.

  The terminal service providing unit 13 has a function of providing a terminal service to the client computers 2-1 to 2-k. More specifically, the terminal service providing unit 13 has the following functions.

When the remote connection request including the user ID “idj” and the password “pj” of the user Uj (1 ≦ j ≦ k) is sent from the management server 3, the virtual desktop environment 11-j for the user Uj And the management information including the user ID “idj”, the status information “disconnected session”, and the resource information are registered in the virtual desktop environment management table 43.
When a remote connection request including the user ID “idj” and the password “pj” is sent from the client computer 2-j, if the virtual desktop environment 11-j for the user Uj is not generated, The virtual desktop environment 11-j for the user Uj is generated, and the management information including the user ID “idj”, the status information “active session”, and the resource information is registered in the virtual desktop environment management table 43, and has already been generated. If so, the status information in the corresponding management information registered in the virtual desktop environment management table 43 is changed from “disconnected session” to “active session”.
When a termination request including the user ID “idj” and the password “pj” is sent from the client computer 2-j, the session with the client computer 2-j is disconnected and the virtual desktop environment management table 43 The status information in the corresponding management information registered in is set as “disconnected session”.
When the termination request including the user ID “idj” and the password “pj” is sent from the management server 3, if the virtual desktop environment 11-j for the user Uj is a disconnected session, the virtual desktop environment 11- Release resources consumed by j.

  The client computers 2-1 to 2-k include terminal service utilization units 21-1 to 21-k. The terminal service utilization units 21-1 to 21-k are realized by, for example, a program called remote desktop connection or a program called terminal service client.

  Based on the schedule information of each of the users U1 to Uk registered in the schedule management unit 42 and the management information registered in the virtual desktop environment management table 43, the remote connection control unit 31 is connected to the server computer 1. It has a function of transmitting a remote connection request and a termination request.

[Description of Operation of Embodiment]
Next, the operation of the present embodiment will be described in detail. It is assumed that schedule information of each user U1 to Uk is registered in the schedule management unit 42 by the schedule setting unit 32.

  As shown in the flowchart of FIG. 4, the remote connection control unit 31 in the management server 3 is one of the schedule information of each user U1 to Uk registered in the schedule management unit 42 (for example, the user Uj (Schedule information) is acquired (step S41), and it is checked whether the start time and end time included in the schedule information satisfy the following expression (1) (step S42). That is, it is checked whether or not the current time is a time between the start time and the end time.

  Start-up time ≦ current time <end time (1)

  If the expression (1) is satisfied (YES in step S42), the remote connection control unit 31 refers to the virtual desktop environment management table 43, and the user ID “idj” of the user Uj is registered there. By checking whether or not the virtual desktop environment 11-j for the user Uj has been generated, it is checked (step S43).

  If it has been generated (YES in step S43), the process returns to step S41, and schedule information of the next user is acquired from the schedule management unit. On the other hand, if the virtual desktop environment 11-j for the user Uj has not been generated (NO in step S43), the password “pj” of the user Uj and the user ID “idj” are stored from the authentication information storage unit 41. Are acquired (step S44), and a remote connection request including them is transmitted to the server 1 (step S45).

  When a remote connection request including a user ID “idj” and a password “pj” is sent from the management server 3 to the terminal service providing unit 13 in the server computer 1, as shown in the flowchart of FIG. The virtual desktop environment 11-j for the user Uj is generated, and management information including the user ID “idj”, the status information “disconnected session”, and the resource information “Rj” is registered in the virtual desktop environment management table 43 ( Steps S51 and S52). As a result, the virtual desktop environment 11-j for the user Uj is generated as a disconnected session.

  After the virtual desktop environment 11-j is generated as described above, the user Uj sends a remote connection request including its own user ID “idj” and password “pj” from the client computer 2-j to the server computer 1. As shown in the flowchart of FIG. 6, the operating system 12 in the server computer 1 performs an authentication process based on the user ID and password (step S61).

  In the case of authentication NG, an error notification is sent to the client computer 2-j. On the other hand, in the case of authentication OK, a virtual desktop environment 11-j for the user Uj is generated by referring to the virtual desktop environment management table 43 after establishing a session with the client computer 2-j. It is checked whether or not it has been completed (step S62). In this example, since the virtual desktop environment 11-j has already been generated, the terminal service providing unit 13 registers state information in the management information for the user Uj registered in the virtual desktop environment management table 43. Is changed from “disconnected session” to “active session”, and a virtual desktop screen is transmitted to the client computer 2-j (steps S63 and S64). Thus, the virtual desktop environment 11-j becomes an active session, and the user Uj can execute an application program using the virtual desktop environment 11-j. That is, the user Uj operates the virtual desktop environment 11-j by operating the virtual desktop screen displayed on the display unit 23-j by the terminal service using unit 21-j using the input unit 22-1. It is possible to execute application programs using them.

  In this example, since the virtual desktop environment 11-j for the user Uj has already been generated, step S62 is YES. If step S62 is NO, the following is performed. Processing is performed. Note that NO in step S62 is a case where the user Uj transmits a remote connection request to the server computer 1 before the activation time scheduled in advance.

  When step S62 is NO, the terminal service providing unit 13 generates a virtual desktop environment 11-j for the user Uj, and stores the user ID “idj” and the status information “active session” in the virtual desktop environment management table 43. ”, Management information consisting of resource information“ Rj ”is registered, and a virtual desktop screen is transmitted to the client computer 2-j (step S67).

  In addition, when the user Uj ends the use of the terminal service, the user Uj inputs the end of the use of the terminal service from the input unit 22-j. Thereby, the terminal service utilization unit 21-j transmits an end request to the server computer 1.

  When receiving the termination request from the client computer 2-j, the operating system 12 disconnects the session with the client computer 2-j (step S71 in FIG. 7), and the terminal service providing unit 13 performs the virtual desktop environment management table 43. The status information in the management information related to the user Uj registered in is changed to “disconnected session” (step S72). At this point, the virtual desktop environment 11-j for the user Uj remains on the server computer 1 as a “disconnected session”. Accordingly, if a remote connection request is sent from the client computer 2-j at this time, the virtual computer screen transmission process is simply performed by performing the status information update process and the virtual desktop screen transmission process in steps S63 and S64 in FIG. The desktop environment 11-j can be made available.

  After the virtual desktop environment 11-j for the user Uj is changed to “disconnected session”, it is assumed that the current time is the end time in the schedule information of the user Uj. After that, it is assumed that the remote connection control unit 31 acquires the schedule information of the user Uj from the schedule management unit 42 (step S41 in FIG. 4). At this time, since the current time has passed the end time in the schedule information of the user Uj, step S42 becomes NO. When step S42 is NO, the remote connection control unit 31 refers to the virtual desktop environment management table 43 and checks whether or not the virtual desktop environment 11-j is a “disconnected session” (step S46). In this example, since “disconnected session” is set in step S72 in FIG. 7, step S46 is YES. When step S46 becomes YES, the remote connection control unit 31 acquires the user ID “idj” and the password “pj” of the user Uj from the authentication information storage unit 41, and transmits an end request including them to the server computer 1. (Steps S47 and S48).

  When a termination request is sent from the management server 3, the terminal service providing unit 13 in the server computer 1 refers to the virtual desktop environment management table 43 as shown in the flowchart of FIG. It is checked whether or not the desktop environment 11-j is “disconnected session” (step S81). In this example, since “disconnected session” is set in step S72 of FIG. 7, the terminal service providing unit 13 determines the resource consumed by the virtual desktop environment 11-j based on the resource information “Rj”. Thereafter, the management information related to the user Uj is deleted from the virtual desktop environment management table 43 (steps S82 and S83). In this example, the virtual desktop environment 11-j for the user Uj is “disconnected session”. However, if the virtual desktop environment 11-j is “active session”, the determination result in step S81 is NO. The terminal service providing unit 13 immediately ends the process. The determination result in step S81 is NO when the user Uj is using the terminal service even after the end time in the schedule information has passed.

  Next, the operation of this embodiment will be described with a specific example.

  Now, for example, it is assumed that the business time of the user U1 is 8:00 to 17:00. In such a case, the user U1 registers the schedule information with the start time “7:00” and the end time “18:00” to the person in charge of the management server 3 using e-mail or the like. Request. Thereby, the person in charge of the management server 3 uses the schedule setting unit 32 to schedule including the user ID “id1”, the start time “07: 0”, and the end time “18:00” of the user U1. Information is registered in the schedule management unit 42. In this example, the start time is set to one hour before the work start time and the end time is set to one hour after the work end time, but this is merely an example.

  The remote connection control unit 31 in the management server 3 always performs the process shown in the flowchart of FIG. 4. When the schedule information of the user U1 is acquired in step S41, “7:00” ≦ current It is checked whether or not “time ≦ 18: 00”. The remote connection control unit 31 acquires the schedule information of the user U1 many times between the start time “7:00” and the end time “18:00”, but now, for example, “7:00” It is assumed that the schedule information of the user U1 is first acquired after “minute”.

  In this case, the determination result of step S42 is YES, and the determination result of the next step S43 is NO. Accordingly, the remote connection control unit 31 transmits a remote connection request including the user ID “id1” and the password “p1” of the user U1 to the server computer 1 (steps S44 and S45).

  When the remote connection request including the user ID “id1” and the password “p1” of the user U1 is sent from the management server 3, the terminal service providing unit 13 in the server computer 1 sends a virtual desktop for the user U1. The environment 11-1 is generated, and the management information of the virtual desktop environment 11-1 is registered in the virtual desktop environment management table 43 (steps S51 and S52 in FIG. 5). Thereafter, until the end time “18:00” is reached, if the schedule information of the user U1 is acquired in step S41, step S43 is always YES, and the remote connection request is sent from the management server 3 to the server computer 1. Will never be sent.

  When the business start time “8:00” is reached, the user U1 transmits a remote connection request including the user ID “id1” and the password “p1” from the client computer 2-1 to the server computer 1.

  Thereby, the terminal service providing unit 13 in the server computer 1 refers to the virtual desktop environment management table 43 and checks whether or not the virtual desktop environment 11-1 for the user U1 has been generated (step S62 in FIG. 6). ). Since the virtual desktop environment 11-1 has already been generated in step S51 of FIG. 5 (YES in step S62), the terminal service providing unit 13 uses the virtual desktop environment 11- registered in the virtual desktop environment management table 43. The status information in the management information 1 is changed to “active session”, and the virtual desktop screen is transmitted to the client computer 2-1 (steps S 63 and S 64). As a result, the user U1 can execute the application program using the virtual desktop environment 11-1. In this case, since the virtual desktop environment 11-1 has already been generated, the user U1 can use the terminal service immediately after the remote connection request.

  Thereafter, the user U1 sends a termination request from the client computer 2-1 to the server computer 1 when the business end time “17:00” is reached. As a result, the terminal service providing unit 13 in the server computer 1 disconnects the session with the client computer 2-1, and changes the status information in the management information of the virtual desktop environment 11-1 to “disconnected session” ( Steps S71 and S72 in FIG.

  Thereafter, it is assumed that the end time “18:00” in the schedule information of the user U1 is reached. When the remote connection control unit 31 first reads the schedule information of the user U1 after the end time “18:00”, step S42 in FIG. 4 is NO and step S46 is YES. A termination request including the user ID “id1” of U1 and the password “p1” is transmitted to the server computer 1 (steps S47 and S48 in FIG. 4).

  As a result, the terminal service providing unit 13 determines that the virtual desktop environment 11-1 is “disconnected session” in step S72 of FIG. 7 (YES in step S81 of FIG. 8). The resource that has been consumed is released, and the management information related to the virtual desktop environment 11-1 is deleted from the virtual desktop environment management table 43 (steps S82 and S83).

[Effect of the embodiment]
According to the present embodiment, the user Uj of the client computer 2-j immediately uses the virtual desktop environment 11-j after the remote connection request without wastefully consuming the resources of the server computer 1. Can be executed. After the remote connection request, the user Uj of the client computer 2-j can immediately use the virtual desktop environment 11-j because the terminal providing unit 13 starts up in the schedule information of the client computer 2-j. This is because the virtual desktop environment 11-j for the client computer 2-j is generated. In addition, the terminal service providing unit 13 is consuming the virtual desktop environment 11-j at the end time in the schedule information of the client computer 2-j so that the remote of the server computer 1 is not wasted. This is because the released resources are released.

  Moreover, according to this Embodiment, it becomes possible to reduce the load of the server computer 1. FIG. This is because the management server 3 having the remote connection control unit 31 that transmits a remote connection request and an end request to the server computer 1 when the start time and end time in the schedule information comes is provided. . That is, since it is not necessary for the server computer 1 to determine whether or not the start time and end time are reached, the load on the server computer 1 can be reduced.
