1. Field of the Invention
The present invention provides a method, system and program product for using Open Mobile Alliance (OMA) device management (DM) alerts to send client commands/requests to an OMA DM server.
2. Related Art
Device management (DM) technology enables the customization, personalization, and servicing of client devices such as wireless phones, personal digital assistants, and embedded technology in cars, houses, clothes, etc. Essentially, DM encompasses all of the necessities for remotely configuring, updating, and repairing client devices operating in the field.
One known technology for enabling DM is SyncML/DM, now referred to as OMA DM. As is known in the art, OMA DM specifies mechanisms and protocols that help achieve management of devices. OMA DM is used to set and retrieve management information from devices where management information consists of data such as configuration settings, user preferences, application settings, software and firmware updates, etc.
Currently, an OMA DM server initiates and controls management actions with a client device. For example, the OMA DM server can ask for client device information (e.g., status, queued events, application information, current parameters, etc.), send management commands (e.g., content/application download, parameter settings, etc.), collect results from the client device, as well as perform other management functions. Unfortunately, however, OMA DM fails to provide a convenient way for a client device to send a command/request to an OMA DM server for a management action to be performed.
In view of the foregoing, there exists a need for a method, system and program product for using OMA DM alerts to send client commands/requests to an OMA DM server. The commands/requests in the OMA DM alerts may include, for example, a request for a list of software (e.g., applications) available for distribution to the client device from the OMA DM server, and a command/request for the distribution of a piece of software from the list of available software to the client device.
In general, the present invention provides a method, system and program product for using OMA DM alerts to send client commands/requests to an OMA DM server.
A first aspect of the present invention provides a computer-implemented method comprising: sending an Open Mobile Alliance (OMA) device management (DM) alert from a client device to an OMA DM server to initiate a management action on the OMA DM server; and sending a reply from the OMA DM server to the client device in response to the OMA DM alert.
A second aspect of the present invention provides a computerized system, comprising: a command/request system for sending an Open Mobile Alliance (OMA) device management (DM) alert from a client device to an OMA DM server to initiate a management action on the OMA DM server; and a request processing system for sending a reply from the OMA DM server to the client device in response to the OMA DM alert.
A third aspect of the present invention provides a program product stored on a recordable medium, comprising: program code for sending an Open Mobile Alliance (OMA) device management (DM) alert from a client device to an OMA DM server to initiate a management action on the OMA DM server; and program code for sending a reply from the OMA DM server to the client device in response to the OMA DM alert.
A fourth aspect of the present invention provides a computer-implemented method, comprising: sending a notification from a client device to an Open Mobile Alliance (OMA) device management (DM) server to initiate a management action on the OMA DM server; and sending a reply from the OMA DM server to the client device in response to the notification.
Therefore, the present invention provides a method, system and program product for using OMA DM alerts to send client commands/requests to an OMA DM server.
These and other features of this invention will be more readily understood from the following detailed description of the various aspects of the invention taken in conjunction with the accompanying drawings in which:
The drawings are merely schematic representations, not intended to portray specific parameters of the invention. The drawings are intended to depict only typical embodiments of the invention, and therefore should not be considered as limiting the scope of the invention. In the drawings, like numbering represents like elements.
In general, the present invention provides a method, system and program product for using OMA DM alerts to send client commands/requests to an OMA DM server. Specifically, under the present invention, a client device running in an OSGi environment sends an alert, in the form of an OMA DM alert, to an OMA DM server to initiate an action (e.g., a client device management action) on the OMA DM server. For example, the client device may send a command/request or notification, using an OMA DM alert, to the OMA DM server for a list of available applications on the server, for a list of available software updates on the server (e.g., application updates, operating system updates, etc.), and/or for other available items on the server that may be required by the client device. In addition, once such a list(s) is provided by the OMA DM server to the client device, the client device may send a command/request, again using an OMA DM alert, for the distribution of available item(s) on the server to the client device. Although the present invention is described herein with regard to client device initiated management actions, such as requesting an application list from an OMA DM server and requesting an application from the application list, it should be apparent that the present invention may be used by a client device to initiate a wide variety of other actions. Further, although the present invention is described herein with regard to an OSGi environment, it should be apparent that the present invention may be used within other suitable computing environments.

Client device 14 is intended to represent any type of computerized device capable of communicating over a network. For example, client device 14 could be a desktop computer (e.g., WIN-32-based), a hand held device, a set top box, a home appliance, a security system, etc.
OMA DM server 12 and client device 14 typically communicate over any type of network such as the Internet, a local area network (LAN), a wide area network (WAN), a virtual private network (VPN), etc. As such, communication between OMA server 12 and client device 14 could occur via a direct hardwired connection (e.g., serial port), or via an addressable connection that may utilize any combination of wireline and/or wireless transmission methods. Moreover, conventional network connectivity, such as Token Ring, Ethernet, WiFi or other conventional communications standards could be used. Still yet, connectivity could be provided by conventional TCP/IP sockets-based protocol. In this instance, client device 14 could utilize an Internet service provider to establish connectivity to OMA server 12.
The client device 14 includes a command/request system 16 for sending an alert, in the form of an OMA DM alert 18, to a request processing system 20 in the OMA DM server 12 to initiate an action (e.g., a client device management action) on the OMA DM server 12. In response to the OMA DM alert 18, the request processing system 20 in the OMA DM server 12 sends a reply 22 to the client device 14. Depending upon the content of the OMA DM alert 18, the reply 22 sent by the OMA DM server 12 to the client device 14 may comprise a list of available software (a list of available OSGi bundles 24 in this example), the software itself (e.g., in an OSGi bundle 24), a request for additional information, a command/request denial, prerequisite requirements, instructions, data, etc. As known, an OSGi bundle is essentially a .JAR or .ZIP file with certain characteristics which enable it to effectively interact with the OSGi framework. In other embodiments of the present invention, a SNMP Trap, a TEC Event, or a SyncML DM alert may be used in lieu of the OMA DM alert 18.

I/O interfaces 36 may comprise any system for exchanging information to/from an external source. External devices/resources 38 may comprise any known type of external device, including speakers, a CRT, LCD screen, handheld device, keyboard, mouse, voice recognition system, speech output system, printer, monitor/display, facsimile, pager, etc. Bus 34 provides a communication link between each of the components in OMA server 12 and likewise may comprise any known type of transmission link, including electrical, optical, wireless, etc.
Storage unit 40 can be any system (e.g., database, repository, etc.) capable of providing storage for information under the present invention. Such information could include, for example, software (OSGi bundles 24 in this example), prerequisite information, device drivers, data, etc. As such, storage unit 40 could include one or more storage devices, such as a magnetic disk drive or an optical disk drive. In another embodiment, storage unit 40 includes data distributed across, for example, a local area network (LAN), wide area network (WAN) or a storage area network (SAN) (not shown). Although not shown, additional components, such as cache memory, communication systems, system software, etc., may be incorporated into the OMA DM server 12. In addition, it should also be appreciated that although not shown, client device 14 would likely include computerized components similar to OMA DM server 12.
Shown in memory 32 of OMA DM server 12 is request processing system 20. The request processing system 20 receives an OMA DM alert 18 from the client device 14, and sends a corresponding reply 22 to the client device 14. It should be understood that the request processing system 20 includes program code/logic for carrying out the functions described herein. To this extent, the request processing system 20 could be realized as a plugin or the like.
The OMA DM alert 18 may be initiated in response to a wide variety of manual or automated activities. For example, a virus scan application 26 on the client device 14 may require updated virus definitions. Accordingly, an OMA DM alert 18 indicating the need for the updated virus definitions will be sent to the OMA DM server 12. The OMA DM alert 18 may be initiated automatically (e.g., once a week) by the virus scan application and/or may be manually initiated (e.g., via a graphical user interface (GUl) 42 presented to a user 44 of the client device 14). In response, the OMA DM server 12 will send a reply 22 including an updated set of virus definitions to the client device 14, which will then be installed by the virus scan application 26. Another example of an event that may initiate an OMA DM alert 18 can occur when a new printer or other peripheral is connected to the client device 14. Upon connection of the peripheral, the client device 14 may query the OMA DM server 12, via an OMA DM alert 18, regarding the availability of an updated device driver for the peripheral. In response, if an updated device driver for the peripheral is available, the OMA DM server 12 will send a reply 22 including the updated device driver to the client device 14. If an updated device driver for the peripheral is not available, the OMA DM server 12 will send a reply 22 to the client device 14 informing the client device 14 that it does not have an updated device driver for the peripheral. It will be apparent that these alert-reply examples are intended to be illustrative only, and that many other alert-reply scenarios are possible.

In step 1, an application 26 running on the client device 14 send a request to an OSGi agent (e.g., command/request system 16) on the client device 14 for a list of available software (OSGi bundles 24 in this example) on the OMA DM server 12. The application 26 communicates to the client device 14 through a service interface. In step 2, the client device 14 sends alerts to a plugin (e.g., request processing system 20) on the OMA DM server 12. The first alert connects the client device 14 to the OMA DM server 12. The client device 14 also sends an OMA DM alert 18 containing the command “RequestOSGibundleList,” to the plugin.
In step 3, in response to receipt of the command “RequestOSGibundleList,” the plugin submits a priority 1 command “ChooseSoftwareToLoadJob.” This is a priority 1 job with an expiration time of t+5 minutes. The plugin then makes sure the job cache is up to date and sends the connect event for the client device 14 to the OMA DM server 12.
In step 4, the plugin sends commands to the client device 14 to remove the old information from the “AvailableSoftwareToLoad” branch of the tree, and to create leaves and nodes describing the software available on the OMA DM server 12. It should be noted that one of the items is an ID—this may be used in a subsequent request by the application 26 for a load of an associated piece of software. Step 4 is listed below in greater detail:
In step 5, the client device 14 sends acknowledgments to the plugin for the commands in step 4. In step 6, the plugin sends a job completion event to the OMA DM server 12 and the job is marked as complete.
A flow diagram illustrating an example of a client initiated software request is illustrated in
In step 3, the plugin submits a SoftwareDistributionJob for the client device 14 to OMA DM server 12 for the requested piece of software. The plugin makes sure the job cache is up to date and sends the connect event for the client device 14 to the OMA DM server 12. In step 4, the requested software is distributed from OMA DM server 12 to the client device 14.
