Description

The present invention relates to a processing apparatus that executes various application processes and displays screen data generated by the processes .

  In recent years, thin client systems that manage resources such as application software and files on the server computer side have been used in an information system of a company, etc., with a computer (client computer) used by employees having only minimum functions. ing.

  The thin client system is also called SBC (Server Based Computing). In a system configuration in which a server and a client are connected via a network, all the application software used by the client is installed on the server (SBC server). Only the screen and the screen data representing the result are received from the server, and only the operation information of the mouse and keystrokes is sent from the client to the server.

  Generally, a thin client system includes a server computer and a plurality of client computers that are remotely connected to the server computer. The server computer generates an application execution environment of each client computer, and the client computer is remotely connected to the server computer and executes various tasks in the application execution environment of the server computer. At this time, the process of creating and using the application execution environment on the server computer takes time.

  Japanese Patent Application Laid-Open No. 2004-151561 discloses a technique relating to a remote connection system that allows a client computer that makes a remote connection request to immediately use a virtual desktop environment. Specifically, the operation schedule (start time and end time) of the application execution environment (virtual desktop environment) of the client computer connected to the server computer is registered in the management server, and the management server is based on this operation schedule. The startup time of each client computer is monitored, and a remote connection request is made to the server computer before the startup time of the client computer to generate a virtual desktop environment in advance. When the server computer actually receives a remote connection request from the client computer at the start time, the server computer immediately connects and uses the already generated virtual desktop environment. As a result, the virtual desktop environment can be used immediately upon remote connection from the client according to the operation schedule.

Part 2022.

Next, the operation in this embodiment will be described.
FIG. 4 is a sequence diagram when the client apparatus 2 is connected to the server apparatus 1. When connecting from the client apparatus 2 to the server apparatus 1, the user inputs a user ID and password for authentication (403), and transmits from the client apparatus 2 to the server apparatus 1 (404). The server device 1 authenticates the transmitted user ID and password against the information stored in the authentication information storage unit 1021 of the storage device 102 (405), and transmits the authentication result to the client device 2 (406). ).

  If the authentication is OK, the client apparatus 2 performs positioning by receiving position data from a GPS satellite using the GPS receiving unit 206, and stores the received position data in the GPS position storage unit 2021 of the storage device 202 (407). ). However, positioning using the GPS receiving unit 206 may be performed in advance instead of at this time.

  Then, the client device 2 transmits the GPS coordinates stored in the GPS position storage unit 2021 of the storage device 202 to the server device 1 (408). The server device 1 stores the sent GPS coordinates in the client GPS position storage unit 1026, and then stores the GPS coordinates in the client GPS position storage unit 1026 with reference to the position-specific application table stored in the position-specific application table storage unit 1022. The application execution environment for the GPS position information is specified.

  FIG. 5 shows the data structure of the position-specific application table. For each position of the client apparatus 2, the items of the position 501, the range 506, the place 507, and the application 502 are stored in association with each other. A position 501 indicates a position serving as a reference for the client apparatus 2 in latitude and longitude, a range 506 indicates a radius from the position serving as a reference for the client apparatus 2, and a place 507 indicates a name of the place corresponding to the position. Application 502 indicates an application executed in the client apparatus 2.

  When there are a plurality of applications to be executed at the same position, a plurality of applications are set. In the example of FIG. 5, three positions 503, 504, and 505 are set, and two applications, a business application C and a business application D, are set at the position 505.

  When a place is specified by position information represented by position coordinates (latitude, longitude) transmitted and measured by the GPS of the client device 2, the place (building, site, etc.) itself is to some extent depending on the size of the building. Since it has a range and there is some error in the position information measured by GPS, the distance between the GPS coordinates (λ1, φ1) of the client device 2 and the value of the position 501 (λ2, φ2) is calculated. If the distance is equal to or smaller than the threshold value Δ (the value in the range 506), it is determined that the place has been reached and the application to be executed by the application 502 is determined. (In this case, the range within the circle of the threshold value Δ indicating the radius centered on the coordinates of the value of the position 501 is the corresponding range).

  For example, if the GPS coordinates of the client device 2 are within a range of 500 m from the value of the position 501 (latitude 35 degrees 46 minutes 27.88 seconds (35.774411), longitude 139 degrees 18 minutes 43.92 seconds (139.3122)), “head office” It is determined that the application for business use A is executed.

  Next, the execution environment of the identified application is generated (410). For example, “business application A” is activated. The application to be started is stored in the application storage unit 1023, and the execution environment of the application to be started for each user-specific application is generated in the user-specific application execution environment storage unit 1025. When the application execution environment is generated according to the position of the client apparatus 2 in this way, the server apparatus 1 transmits screen data indicating that the execution environment has been generated to the client apparatus 2 (411). The client device 2 displays the received screen data on the display unit 205.

  When executing the started application, first, a key event or the like generated by an input operation (413) of the client device 2 is transmitted to the server device 1 (414). The server device 1 executes processing corresponding to the received key event (415), creates screen data as a result of the processing, and transmits it to the client device 2 (416). The client apparatus 2 displays the received screen data on the display unit 205 (417). The sequence from 413 to 417 is repeated until a session disconnection request is transmitted from the client device 2 to the server device 1 and the session is disconnected (418).

  Next, processing executed under the control of the control unit 201 in the client device 2 when connected to the server device 1 will be described with reference to the flowchart of FIG.

  First, the GPS receiving unit 206 receives GPS position information from a GPS satellite, stores the received GPS position information in the GPS position storage unit 2021, and then transmits it to the server device 1 (step S1).

  And it will be in the state which waits reception of screen data from the server apparatus 1 (step S2). When screen data is received from the server device 1 (step S2; YES), the screen data is stored in the display content storage unit 2022 and displayed on the display unit 205 (step S3). When screen data is not received from the server apparatus 1 (step S2; NO), it will be in the state which waits for generation | occurrence | production of input data (step S4).

  When the input data generated by the user's input operation is received by the input unit 203 (step S2; YES), the input data is transmitted to the server device 1 (step S5).

  Next, processing executed under the control of the control unit 101 in the server device 1 when a connection request from the client device 2 is received will be described with reference to the flowchart of FIG.

  When the user ID and password of the user X are received from the client device 2 of the user X, a user authentication process is performed by collating with the data stored in the authentication information storage unit 1021 (step S10).

  If the authentication result in step S10 is NG (step S11; NO), an error message is transmitted to the client device 2 and this process ends. On the other hand, if the authentication result in step S10 is OK (step S11; YES), a message notifying that the authentication result is OK is transmitted to the client device 2.

  Next, by referring to the user-specific application execution environment storage unit 1025, it is determined whether or not an application execution environment corresponding to the client device 2 of the user X has been generated (step S12).

  When it is determined that the application execution environment has not been generated (step S12; NO), processing for generating the application execution environment is performed (step S13), and screen data corresponding to the generated application execution environment is obtained. It is transmitted to the client device 2 (step S14).

  The application execution environment generation process in step S13 will be described in detail later with reference to FIG. When it is determined that the application execution environment has been generated (step S12; YES), screen data corresponding to the application execution environment is transmitted to the client device 2 (step S14).

  If input data is received from the client device 2 after transmission of the screen data in step S14 (step S15; YES), if the input data does not request session disconnection (step S16; NO), the input Data is passed to the activation application and processed (step S17).

  Then, the screen data representing the execution result of the application in step S17 is transmitted to the client apparatus 2 (step S18), the process returns to step S15, and a waiting state for data received from the client apparatus 2 is entered. When the input data from the client device 2 is a request for session disconnection (step S16; YES), this process ends.

  Next, the application execution environment generation process in step S13 of FIG. 7 will be described with reference to the flowchart of FIG.

  First, the application corresponding to the position of the client apparatus 2 is specified by referring to the position-specific application table stored in the position-specific application table storage section from the GPS position stored in the client GPS position storage section 1026 (step S1). S121).

  Next, a resource (such as a storage area of the user-specific application execution environment storage unit 1025) for the application identified in step S121 is acquired (step S122). An application execution environment is generated by starting an application specified from among applications stored in the application storage unit 1023. The generated application execution environment data is stored in the user-specific application execution environment storage unit 1025 (step S123).

  As described above, according to the remote connection system 100 of the present embodiment, even when the user uses the portable client device 2 (client computer) at a plurality of locations, application execution according to the location of the client device 2 is performed. Since the server device 1 generates the environment in advance, the client device 2 can immediately use the application execution environment simply by connecting to the server device 1, which can improve the convenience for the user. it can.

  The processes of the server apparatus 1 and the client apparatus 2 described in the embodiment, that is, the processes shown in the flowcharts of FIGS. 6 to 8 are all stored in the storage device 102 and the storage device 202 as a computer-readable program.
