Patent Document

[0001]    This application claims the benefit, pursuant to 35 U.S.C. §119(e), of U.S. Provisional Patent Application entitled “REMOTE COMMAND EXECUTION FROM MOBILE DEVICES BROKERED BY A CENTRALIZED SYSTEM,” filed on Jun. 20, 2008 and assigned application No. 61/132,571 the disclosure of which is incorporated herein by reference in its entirety. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The invention relates to a system and method for execution of commands on a remote computer from a mobile device. More particularly, the invention relates to a system and method for execution of commands on a remote computer from a mobile device for the purposes of verification, diagnose, remediation, and communication regarding a condition of the remote computer or device managed by the remote computer. 
       BACKGROUND OF THE INVENTION 
       [0003]    Many computer monitoring systems exist for the purpose of detecting a state or condition of a computer system or of the applications running on it. Once an “alarm” has been detected, it needs to be verified, diagnosed, remediated, and eventually the status of the alarm needs to be communicated to others. In many cases, the various tasks are done through a computer with remote control capabilities and then using many tools on an ad-hoc basis. 
         [0004]    Remote control involves logging into a remote computer system as if one is a user of that system. The effect is to have the same access rights, control, and display as if the user were sitting at the local keyboard and display. Several remote control solutions offer variations, which allow tunneling and in some cases, the remote control display can be transmitted to a mobile device. 
         [0005]    The issue with remote control on a mobile device is that most remote control solutions were designed to be used on a desktop computer with a full display and mouse. Mobile devices have limited navigation, bandwidth, and display making it cumbersome to use traditional remote control 
       SUMMARY 
       [0006]    The invention relates to a system and methodology of allowing users to easily execute commands for the purpose of verification, diagnosis, remediation, and communication from the perspective of a remote computer from their mobile device. The invention requires installation of a robot on the remote computer where commands will be executed. The configuration of the pre-defined commands, which are pre-built actions can be carried out by the robot along with their parameters. 
         [0007]    The user interface for executing these remote commands consists mostly of listings of robots, their groupings, pre-defined searches, and their commands, such that navigation can be done by navigating around hyperlinks rather than controlling a screen with a mouse. 
         [0008]    Both the robots and mobile device connect to a central backend server that acts as a broker for the transactions, alleviating connectivity issues related to mobile devices and robots on remote systems with firewalls. The central server ensures security of the transaction and then authentication of the mobile device user. It also centrally stores the commands to be executed. The robots will periodically connect with the backend server through a web service call requesting the command to be executed, perform the command, and return the result. Commands can be scheduled to be executed in the future as well at a pre-determined time. The central server acts as a scheduler and mediator for this transaction. 
         [0009]    Further, some actions may be scheduled and executed in a long-running process. In such cases, the user of the mobile device will be notified that the command was accepted and allowed to continue. Then when the robot has executed the command, the result will be sent to the mobile device either as an email or an alert to the mobile interface.

     DETAILED DESCRIPTION 
       [0018]    One or more exemplary embodiments of the invention are described below in detail. The disclosed embodiments are intended to be illustrative only since numerous modifications and variations therein will be apparent to those of ordinary skill in the art. In reference to the drawings, like numbers will indicate like parts continuously throughout the views. 
         [0019]    Aspects of the present invention relate to a next generation system for performing commands on remote computer systems and devices primarily from mobile devices. Traditionally, there have been two primary methodologies of accessing remote systems.  FIG. 1 , remote screen sharing, illustrates systems where a rendition of the screen or virtual screen on a remote system  110  is replicated. This can be accomplished by terminal or remote desktop protocols.  FIG. 2 , tool based control, illustrates existing systems where a program is run directly on the technician&#39;s desktop  205  and accesses an agent  215  on a remote server  110 . In this model, the tools  220  communicates directly with the agent  215  and results are displayed immediately on the tool. 
         [0020]    Mobile devices present unique issues in that direct connections are not always possible. As depicted in  FIG. 3 , the present invention resolves this issue by employing a central broker  320  that acts as an intermediary between the mobile device  305  and the remote server  110 . Modern mobile devices have access to web-based requests systems, either threw a web browser  315  or a programmatic interface running on the mobile device  305  directly. Requests are sent to the central broker  320 , which queues up the requests for robots  325 . Robots  325  periodically poll the central broker  320 , carry out commands and return the results to the central broker  320  to pass back to the mobile device  305  or technician&#39;s desktop  310 . The protocol employed by the robot  325  must be able to tunnel through firewalls  335  and be outbound only for security reasons. An embodiment of the present invention is to use the HTTPS protocol. 
         [0021]      FIG. 4  illustrates the preferred embodiment of the robot  325  function. Periodically, the robot  325  will poll the central broker  320  as shown in step  405 . The result from the poll can be no command at this time or a command request. If the command request is marked as scheduled, it is added to the schedule queue  415 . The scheduler  420  periodically checks the queue to see if it should execute. When the scheduler finds a command request to execute it queues it adds it to the execution queue  410 . If the command request was not flagged as scheduled, it will be immediately added to the execution queue  410 . Command are then executed  425 . If the command is flagged as asynchronous, acknowledgment of the execution is returned immediately to the central broker  440 . The robot continues to wait for the command  445 . When the result from the command execution is returned it is sent back to the central broker  450 . Asynchronous execution is of extreme value in situations where a mobile device needs to be used to execute commands. In many cases, the commands may be long running and connectivity from mobile devices may be extremely transient. Synchronous commands are executed  425  then the robot goes into a wait state for the result  430 . The result is then immediately passed back to the central broker  435 . 
         [0022]    The flow chart depicted in  FIG. 5  illustrates the preferred embodiment of the central broker  320 . The robot  325  periodically polls the central broker  320  through a web service call to the web services listener  510 . If the poll is an asynchronous result, it is routed to the asynchronous result receiver  515  and then sent to the notification engine  530 . In this particular embodiment, the notification engine can send out an email  535 . If the request being sent to the web service listener  510  is a request for command and not an asynchronous result, the web service listener  510  polls the command queue  520  for commands for the robot  325 . All appropriate commands are sent back to the robot  325 . From the Mobile and Desktop Execution Site  525 , technicians from a desktop  310  or a mobile device  305  can add commands to the command queue  520 . 
         [0023]    A significant aspect of the present invention is the concept of a command.  FIG. 6  shows the structure of commands. A command is defined as a built-in action  605  along with a set of parameters  610 . The significance of the command definition is that it embodies predefined parameters by a command label  615  that can be used in an optimized mobile interface. 
         [0024]    The command labels  615  form the basis of embodiment of the mobile interface depicted in  FIG. 7 . To adhere to the constraints of small screen navigation, no typing or minimal typing is needed and a list of command labels  615  set-up as hyperlinks is presented in various listings.  FIG. 7  shows a possible embodiment of the present invention&#39;s mobile interface as a vertical listing that is highly compatible with all modern cellular devices. 
         [0025]    The uniqueness of the present invention lies in its ability to execute commands on remote systems taking into account the nature of mobile devices and the limitations thereof. The present invention removes barriers to command execution in mobile environments on a host of servers using a central broker  320  and utilizing a unique command interface  525  that allows encapsulation of actions and parameters into command labels  615 , allowing technicians to easily perform commands remotely on a remote server from a mobile device giving interface limitations.
