This invention generally relates to a system and method of seamlessly updating, correcting, modifying or upgrading software on an electronics device.
Computer software is constantly updated to keep pace with new features, prevent problems from arising, or fix known or recurrent problems. Users exploit several mechanisms, each requiring a certain amount of computer resources, involvement and decision-making on the part of the user, to keep up with available updates. Various methods for updating software include patching and hardware and software upgrades.
Providers typically determine when, how, at what cost, and under what circumstances upgrades are made available. Inevitably, upgrading requires the time and energy of the user device, and some level of user involvement. As a general matter, any increase in time or effort required by the user, or any annoyance experienced due to reduced device functionality while an upgrade occurs, reduces the likelihood that the user actively chooses to upgrade their software, especially if they are not experiencing a problem.
Providers are increasingly providing upgrades via a patch, a discreet portion of computer code downloaded via a network, such as the Internet, as opposed to upgrading via hardware and software upgrades. This is because the process of upgrading via hardware and software upgrades often requires more time than that of a patch as it requires the user to physically load the update onto their user device. The possibility of user error is also increased as greater activity is required on the part of the user to implement upgrades. Alternatively, the process of upgrading via a patch does not require any physical loading of software or hardware by the user. However, upgrading a user's system via the patch does require consideration of the network connection quality, processing capacity of the user device, and user's ability and willingness to properly download and implement the patch.
A patch can be an upgrade, a bug fix, a new hardware driver or update to address new issues such as security, stability or other end-user problems. Most patches are free to download, but ultimately the provider determines which versions of their software are updated for free. In some cases, only registered users may get certain upgrades. At other times the only way to upgrade is to purchase the newer version at a discounted price, which requires reinstallation of the program. Typically, a patch can be installed concurrent with an existing program depending on the supplier and the nature of the patch.
Providers often force, or push, upgrades to the user device and users are typically denied access to the device until upgrades are installed. Alternatively, a provider may prevent a user from closing out of an application until the upgrade is downloaded. When the provider forces downloads of upgrades the user's device typically functions more slowly or not at all until upgrades are downloaded. Alternatively, users may request, or pull, upgrades by accepting them upon notification provided by the provider that upgrades are available. The download of the upgrade is typically contemporaneous with the user's request and consumes computer resources causing delay in the device's utility to the user.
Generally, users must conform to parameters set by the providers if they are to obtain upgrades. The prior art method of receiving upgrades is problematic for several reasons. The provider typically does not take into account that the user's device is slowed while the download takes place and that the user's experience while using their device is negatively impacted by a delay caused by downloading an upgrade. Alternatively, when upgrades are pulled, users are required to make decisions about when to suffer a delay on the user device on a case-by-case basis. Further, users pulling upgrades are often required to determine the correct upgrade for their system with no or little knowledge or guidance. In either case, the provider may limit the size of the upgrade to be downloaded or provide the upgrade in serial form to reduce the delay experienced by the download.
In situations where the provider forces the user to accept updates, the user typically has no choice as to when or how such upgrades occur. The user experiences interruption in the functionality of the user device and, worse still, the delay may be unexpected and/or frustrate the user's use of their device. In situations where the upgrade is requested by the user, they typically have limited options to refuse a download. In the event that the user chooses to download the upgrade, the upgrade starts downloading to the user device immediately and, during the time of the upgrade, the user experiences reduced functionality of the user device. Some users have developed a habit of choosing not to upgrade due to the temporary interruption in the use of the device. The burden of upgrading to resolve problems often exacerbates the frustration of the user experiencing an underlying problem and makes finding a less intrusive means of providing upgrades to clients and users desirable. In the long term, failure to voluntarily upgrade acts as a detriment to providers, clients and users, as upgrades allow users to experience the best product the provider has to offer, resolve problems, and prevent problems from arising.
There exists a need to provide users with a less burdensome means of upgrading their devices by providing users with the means to select when and in what manner downloading can occur that reduces the interruption of their use of their device.
The present invention relates to a method and apparatus for providing a user of an electronic device with an Automatic Upgrade Functionality (AUF), the ability to automatically upgrade software installations with a configurable amount of user interaction and interruption. That is, an upgrade is configured to provide full or limited notification of the upgrade to the user or is completely silent.
The present invention augments existing methods for patch, soft and hard upgrades by providing an upgrade facility with more control over the user experience. AUF provides an innocuous upgrade service to users and/or clients compared to conventional methods, where users and/or clients are forced to quit the application, download an installer program and then run it manually to upgrade their application, or are burdened by an undesirable reduction in the use of their device. AUF provides for a less intrusive way for providers to supply users and/or clients with upgrades, and for users and/or clients to implement those upgrades. Using AUF, the user/client pre-selects the parameters under which they prefer receiving upgrades, or the client/server determines the best time to download an upgrade.
There are several steps in the AUF process. The AUF program can be stored on either the client or the server. The user's device connects to the server using an existing connection protocol. As part of the server response to the connection, the server and/or client transmit AUF data. The user may or may not access the AUF to set personal preferences using several available parameters to control the AUF process. The parameters can be preset to automatically upgrade the software or to upgrade the software according to user preference. In one embodiment, any upgrade downloaded according to the AUF parameters is implemented automatically at a time when the user is not otherwise using the device. Alternatively, any upgrade downloaded according to the AUF parameters is implemented automatically when the software is launched. In an embodiment, AUF parameters are preset to automatically upgrade the device with upgrades that are available from secure sources at times when the client is used the least.
In one embodiment, to download an update, the user device connects to the download server and downloads the upgrade using an URL and priority parameters. The client verifies that the downloaded upgrade is unchanged and prepares the upgrade to be launched automatically, or at the next client startup. Verification uses the checksum or other security parameter returned during initiation to ensure that the downloaded update is correct. If the parameters are set to notify the user, the user is notified accordingly.
One embodiment has a single point of execution. For example, a small launch executable can be the main entry point for users to run the application. The launcher, when run, reads a known registry key and allows the current client executable to run. When a new version of the software is downloaded successfully, the registry key is updated accordingly. For example, the launcher can be called “Client.exe” and the client executable is called “Client-<version>.dat”, where “<version>” is the version number of the executable.
In one embodiment, the download request and the user notification are handled outside of the main client thread, therefore the user is free to use the client while the AUF process is completed. Download priority is implemented by setting a thread priority control. Therefore, by virtue of the thread scheduler, the download thread gets more or less CPU time to complete the download depending on the settings.
In an embodiment, the request for software updates automatically indicates the current version and any patch version used by the user device issuing the request. The server and/or the client responds by comparing the version information with available updates to determine whether or not to upgrade the client.
Verification that the download is successful utilizes a checksum or similar program. The checksum is used to prevent corrupted downloads. For improved security, a cryptographic hash (e.g. MD5 or SHA1) or other similar security measure can be used.
In an embodiment, because AUF is invoked multiple times for the lifetime of a client installation, “old” computer code can collect on the user's device. To prevent this from becoming a resource leak and to prevent unnecessary use of storage space, only the most recently used version is retained. For example, a software upgrade from version 3.6 to 3.7, and then 3.7 to 3.8, results in removal of the 3.6 version from the device. When version 3.8 is upgraded to 3.9, the 3.7 version is removed. Alternatively, prior versions are deleted in accordance with a predetermined amount of time or are stored elsewhere.
In an embodiment, AUF can download an update obscured to prevent it from being considered a security risk. The executable can be packaged as a .CAB archive file or other similar file and can be given a specific name to identify the version upgrade.
Downgrades can also be performed using the present invention. Users have the option to refuse upgrades, either in whole, or only for specific applications, thereby selectively maintaining pre-updated material. This feature is especially useful where the compatibility of a program with other programs is lost upon installation of an upgrade, or where the user has a preference for a particular version of the application.
In one embodiment, upon initiation of the AUF, the server notifies the user device that an upgrade is available. This is done via a defined protocol between the user device and the server.
In one embodiment, registry settings include an option to enable or disable the AUF and checksum verification; and indicate the current and previous versions of the client. In one embodiment, hidden registry settings pertaining to AUF are also created.
In one embodiment, little or no user intervention is required, and the user continues to use the device and software uninterrupted and the actual upgrade occurs at the next launch. The update method includes automatically downloading an upgrade in the background so that the next time the user starts their device the software upgrade is automatically loaded and the software upgraded.
It is an object of this invention to provide the user with the greatest amount of control possible, such that they are encouraged to upgrade despite interruption in the use of their computer.
The above and still further objects, features and advantages of the present invention will become apparent upon consideration of the following detailed description of a specific embodiment thereof, especially when taken in conjunction with the accompanying drawings wherein like reference numerals in the various figures are utilized to designate like components, and wherein:
The system and method provides a user of an electronic device with an AUF, that is, the ability to automatically upgrade software installations with a configurable amount of user interaction and interruption.
Another step is the setting one or multiple of the available service parameters (step 202). The service parameters 300 can be stored either on at least one of the client 104 and server 108. The parameters 300 are understood by the client 104 and server 108. The user 100, the client 104, the server 108, can set the parameters 300 on the client 104 and/or server 108. Alternatively, the parameters 300 can be preset as part of the AUF upon initiating the client 104 or may be preset and later altered according to the user's 100 preferences. In one embodiment, the user 100 is not involved, and the AUF functions automatically according to service parameters 300. Other embodiments include some of or all of the following parameters 300 as set by one of the user 100 or the client 104.
A notification parameter 302 determines the amount of notification to the user 100. In one embodiment, the notification parameter 302 is set to either notify or not to notify the user 100 under various circumstance, including but not limited to those set forth below. The notification parameter 302 can be set to notify user 100 that the upgrade is available, to request approval before downloading an upgrade, that the upgrade download was successful, to indicate the download source and/or security, and to notify the user 100 of a need for further instruction regarding particular downloads. The client 104 can also be notified. The notification parameter 302 can be set to include notification of, among others, only certain types of upgrades, upgrades provided by particular providers, upgrades that are provided by a secure source, upgrades exceeding a certain size, or upgrades expected to require more than a certain amount of time to download. Additionally, the notification parameter 302 can be set to request notification at specific times, or a delayed summary notification of all upgrade downloads over a specified time.
Priority parameter 304 is set to determine the priority with which downloads occur and allows user 100, client 104 and/or server 108 to set a range of priority for downloading requested information. For example, downloads of greater priority result in faster download performance with the understanding that such downloads have the highest probability that the user 100 can be disturbed. Downloads of lower priority result in slower download performance, but are less likely to disturb the user 100.
Source parameter 306 provides the user 100 or instructs the client 104 of the option to download depending on the available source. The source parameter 306 can be set to only download from particular sources, or where download security is also available. For example, if the download is from an undesirable unsecured source, the download does not occur. In the instance that a download is selected on the basis that its source is unsecured or otherwise undesirable, the option to have the client 104, either automatically and/or upon notice to the user 100, locate a provider-approved or a secure source of the upgrade is available.
Security parameter 308 provides the user 100 and/or the client 104 the option to download a checksum, indicating that a checksum is used to verify that the download was not corrupted. This option is available using methods known in the art, such as by using either MD5 or SHA hashes.
Compatibility parameter 310 can be set to provide one or more of the user 100, client 104 and server 108 the option determine the compatibility of available downloads with other programs located on user device 102, and the ability to refuse to download those upgrades and/or download upgrades accordingly. In one embodiment, another provider's 106 information is used to assess any conflicts between existing software on the user device 102 and the suggested download. This embodiment results in two downloads, one to upgrade for each software package, so that they are compatible.
Costs parameter 312 can be set values for prompting certain responses from the user 100 and or the client 104 when there is a cost associated with the download and/or according to the amount of the cost. In one embodiment, the user 100 and or the client 104, sets up an automatic account on the client 104 or through a third party so that payment is made and the upgrade is downloaded.
Timing parameter 314 can be set to request that downloads only occur at specific times. In an embodiment, the client 104 can be set to independently determine optimal times for download, such as when the client is used the least. Alternatively, the client 104 requests to re-initiate contact with the provider 106 and/or the server 108 in order to download upgrades at a certain time. For example, where software 103 did not upgrade so that the user's 100 use of software 103 may be less likely to be impeded in the short term, the client 104 can note the URL of the site where the upgrade download is available and return to that site in accordance with the parameters set for AUF.
Bandwidth parameter 316 can be set to request that an upgrade be delivered using only a certain amount of available bandwidth, or not exceeding a certain amount of bandwidth. This feature is useful for devices 102 that need to keep a certain amount of bandwidth available for other uses.
Size parameter 318 can be set to request that an upgrade be delivered according to size, or not exceeding a certain size. In one embodiment, the client 104 requests information regarding the download size and requests that the upgrade be sent as one large file or multiple small files delivered one at a time.
Returning to
A request for information is sent and received by the client 104 or the server 108 (step 206). In one embodiment, the request to obtain information can be sent from the client 104 to the server 108 via the network 110 automatically by the client 104 or can be sent under the direction of the user 100. In an embodiment, the request to obtain information is sent and/or received in accordance with the parameters 300.
One of the client 104 and the server 108 formulate a response to requests for information (step 208). A response is formulated according to the set service parameters 202. The requested information is then delivered to the requesting client 104 or server 108 via the network 110 (step 210).
The delivery of the requested information 210 is made according to the set service parameters 300. In one embodiment, the software modification is delivered in encrypted and/or compressed form. In another embodiment, the delivery of the requested information 210 is accompanied by the delivery of instructions to the user for the proper installation of the update.
Requested information is installed (step 212) by the client 104, the user 100 and/or the server 108. In one embodiment, proper installation of the requested information on the client 104 is ensured by the client 104 and/or the server 108.
