Patent Application
20120210310
This disclosure relates to updating applications and more particularly to systems and methods for efficiently updating applications that reside on a computing device.
It is now common to use mobile devices to obtain information on a continuous basis. Such data could be, for example, the latest weather, sports scores, or the data could pertain to airline flight information or any other type of information that is presented to, or accessed by the user of the device from time to time. This presentation of the information to the user is controlled by an application (service) that then needs to be updated on some basis, either periodically, or on demand, or when bandwidth is available. The updating of the application can be simply that the data (i.e. the actual weather or sports information) needs to be refreshed or often it happens that the application itself needs to be updated to accommodate new features, to repair errors, etc.
The problem then becomes how and when to perform the update so that it is both timely available and does not degrade the present use of the device nor tax the device battery while also using as little processing time as possible. For example, battery life is impacted when radio transmission occurs in order to download the data from a network server. Thus, the time when the new data crosses the air interface is an issue.
Another aspect of the problem is that sometimes the update data is available while the user is using the existing application. In such situations, updating the application, or updating the data used by the application is impractical since doing so at that particular time will interfere with the user's current activity.
The present invention is directed to systems and methods which schedule the updating of applications and/or application data to occur according to a priority dependant upon a variety of dynamically changing factors. In one embodiment, a service manager schedules the update from the network server to occur when the device on which the updating application resides is not otherwise busy with functions that would cause a burden on network usage or with the user's current experience with the device or with battery life. The new data is transferred from the network server to the wireless device, upgrading on an irregular schedule based on at least some factors individual to the particular applications. In the embodiment shown, after the service manager has determined that new data has been transferred to the device for a particular application, then that application is prompted to begin the data upgrade process only at a time when the impact on the user and on the battery level of the device is only minimally affected.
The foregoing has outlined rather broadly the features and technical advantages of the present invention in order that the detailed description of the invention that follows may be better understood. Additional features and advantages of the invention will be described hereinafter which form the subject of the claims of the invention. It should be appreciated by those skilled in the art that the conception and specific embodiment disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present invention. It should also be realized by those skilled in the art that such equivalent constructions do not depart from the spirit and scope of the invention as set forth in the appended claims. The novel features which are believed to be characteristic of the invention, both as to its organization and method of operation, together with further objects and advantages will be better understood from the following description when considered in connection with the accompanying figures. It is to be expressly understood, however, that each of the figures is provided for the purpose of illustration and description only and is not intended as a definition of the limits of the present invention.
For a more complete understanding of the present invention, reference is now made to the following descriptions taken in conjunction with the accompanying drawings, in which:
Device 10 contains service manager 13 which in turn controls various services (or data types) 13-1 to 13-N. Each of the services 13-1 to 13-N has associated therewith a priority function 14. The purpose of each service 13-1 through 13-N is to perform a particular function (application) that ultimately results in data displayed to the user via display 15. Each service 13-1 through 13-N requires some time (bandwidth) on the wireless interface and service manager 13 balancing each bandwidth request against all other service bandwidth requests against a number of factors. The priority of each service is incorporated into the priority function for each service. Since the overall connection has a bandwidth limit, the availability of the connection to any particular service is balanced across all services according to an individual priority function associated with each service. Since the priority function for a given service can change from time to time, the use of the connection is dynamically balanced and thus adapts to user load patterns in accordance with each user's needs and desires. This adaptation can use a variety of functions, such as, for example, Baysian or support vector machine and can support adaptive or designed balancing or combinations thereof.
For example, assume a user desires to use only one megabyte per day. That megabyte is rationed out in some order during the day according to a plan for that user. The plan can, for example, be based on statistics, for example, B-spline or linear, for that user, or on anyone of many other techniques, such as, for example, probability of usage of target application or data, neural network, location-based function, GPS. The air transport time can be rationed at so many megabytes per hour, if desired. The service manager then will only allow the connection to be used up to the threshold limit. To accomplish this, the service manager periodically pulls through the list of services that require bandwidth and processes the highest priority service first until it reaches the bandwidth limit set for the connection. The service manager then waits until the next pulling interval and repeats the process. The priority functions themselves are constantly changing their priority levels and thus at each polling opportunity the highest priority functions are served first.
For example, assume that a user desires to have a weather application, a news application and a sports application. The weather application may have a high priority assigned to it during the hours of 6 AM to say 9 AM. Thus, during these hours the weather information is updated every, say ten minutes. Likewise, the news application has a high priority in the morning but then switches so that only “breaking” news stories are reported during the day. The sports application has a priority such that scores are reported only at 6 AM and then again only at 10 PM, except that when a favorite team (or teams) are actually playing, then the priority changes to every five minutes.
Another example would be when the user performs an action, such as pressing a key or changing the view on the display. This action then could immediately change the priority function of the associated application (service). This then would allow the service manager to control updates on a more immediate basis.
During the time the service manager is managing the connection, there can be a side channel of HTTP headers, such as headers 101. These side channel headers piggyback on other messages. For instance, if service A is communicating with server 11, service B can also communicate with the server at the same time on the same message using a side channel message such as message 102.
The purpose of the side channel is to process certain class of service requests that are small but frequent or potentially frequent, but where it is not necessary to establish an explicit transaction on the network. Thus, when one service makes a request and gets a response, several other services can have their small but important requests multiplexed on the established requests so that they effectively share that time slice. An example would be for an application to check for the presence of an update such that if an update exists, then time can be scheduled to actually update the application. It is the side channel that the service manager uses to determine when an update is available so that the service manager can then schedule that update to be transmitted across the air interface at the most efficient time.
Note that while
Another example of dynamic function changing is when messages are being sent back and forth to another mobile device. The user then wants the message sending and receiving service to have a high priority during this exchange but then also wants that priority to taper off over time as the conversation dies so that the device does not use up a lot of network bandwidth checking for messages. The priority function could be anything that is reset by user actions. Examples of priority changes are: periodic, constant, decreasing priority, increasing priority.
Another example would be using statistics about times when network access has been accomplished or when things are available. This would work well for applications that change over time, such as a traffic map. The priority function would track the changes in traffic patterns during, for example, rush hours and could therefore dynamically increase and decrease its priority assigned to updating the information from the server.
The priority could be tailored to usage. For instance, a user may regularly begin his/her day by looking at the traffic information, then checking the news and then looking at the weather icon on the display. These items can be clustered to update as a group. Using this arrangement, the system might be a little late on traffic, but will be ahead on the other services in that group. For a flight icon (tile), for instance, one of things that affects the priority might be the proximity in time to the flight. As the time comes closer the priority can go higher for updating departure and gate information. The system might update once a day when the flight is a couple of days away and then start updating at, say, 15 minute intervals, when it is within a few hours of flight time.
Also the system might have a flight tile that contains several airlines on it. When the tile is selected, the system could determine which airline has the highest priority from the several possible airlines on the tile with the priority based on calendar information available to the system. Thus, if the user is booked on an American Airlines flight, then the user probably does not need an update of Continental flights at that point in time.
Thus, by having access to other information, the priority of the information into the phone can be managed consistent with reducing bandwidth and battery drain and to give the user increased value from the device. Thus, when it is snowing outside, the phone could sound an alarm earlier than normal to alert the user to longer commute times based on the knowledge of the weather and the user's calendar of scheduled activities.
Manager 21 signals (201) to the application that an upgrade is available. Manager 21 can, if desired, operate based on the adaptive techniques as discussed above, for example. linear, B-spline, Bayesian, probability of usage of target application, neural network, location-based function, GPS. The application then invokes (202) a stub application which provides feedback (203) to the user that an update is about to occur. This feedback includes hiding the application from view by the user so that during the upgrade process the user cannot have access to the application. This hiding can be, for example, removing (or dimming) the application icon from the device display. The stub application moves the upgrade into position to be used by the application and signals ready (204) to the application. If desired, the upgrader can display progress to the user such as time remaining, etc. Some applications can take a relatively long time to close down (quit running) (205) and thus even though the updated data file is small, the total upgrade time can be relatively long. During this period of time, some applications must write out their internal state and save the files so as to free up memory, etc. which functions can take some time. When the application is completely closed, then it is unloaded from memory and the upgrader application receives (206) an event signal indicating that the application has exited.
At this point, the upgrader application is still in control of the upgrade progress, including the display, and begins copying files. Again, if desired, update progress can be given to the user. The files are then upgraded with the new data (207) and when the files are completely updated, the upgrader signals (208) the application to restart. When the restart is complete, the application signals (209) that fact to the upgrader which then exits (210), allowing the application icon to again become active for activation when desired by the device user. In one embodiment, the operations in the device are controlled by machine executable code running under control of, for example, processor 131.
Process 304 determines whether there are side channel communications that need to occur, and if so, process 305 schedules those communications.
Processes 401, 402 and 403 of embodiment 40, as shown in
Process 404 then coordinates this information with process 310, as shown in
