I. Field of the Invention
The present invention generally relates to data networks and computer communications across the data networks. More particularly, the invention relates to the licensing of software applications being executed on wireless devices from one or more application managing servers on a wireless data network.
II. Description of the Related Art
Wireless devices, such as cellular telephones, communicate packets including voice and data over a wireless network. Cellular telephones themselves are being manufactured with increased computing capabilities and are becoming tantamount to personal computers and hand-held personal digital assistants (“PDAs”). These “smart” cellular telephone have installed application programming interfaces (“APIs”) onto their local computer platform that allow software developers to create software applications that operate on the cellular telephone. The API sits between the wireless device system software and the software application, making the cellular telephone functionality available to the application without requiring the software developer to have the specific cellular telephone system source code.
The software applications can come pre-loaded at the time the wireless telephone is manufactured, or the user may later request that additional programs be downloaded over cellular telecommunication carrier networks, where the programs are executable on the wireless telephone. As a result, users of wireless telephones can customize their wireless telephones with programs, such as games, printed media, stock updates, news, or any other type of information or program available for download through the wireless network. Each of these software applications normally requires a license for the user to legally use the software on the wireless device. The license can be copied to the wireless device from the server with the software, or the license can be created on the wireless device as a file, key, or other resident object.
If a license is meant to limit the use of the software application to a finite duration, such as a specific number of times of execution or number of days of use, then once the license expires, a user of the wireless device must typically either download a new license to incorporate into the software application, or reinstall the entire software application if further use of the application is desired. The wireless device API normally checks the software either at the time execution is requested or at some other period to determine if the software is licensed for use on the platform. Alternatively, the wireless device can contact a server every time the execution of the software application is requested and the server, which then either sends permission or denial for execution of the application, can determine if a valid license is present. Although, if a communication link is expensive, such as a cellular telephone call, then the monitoring of the license preferably occurs on the wireless device.
If the license has expired, the wireless device will not execute the unlicensed software application, and if the user desires additional use of the software application, the user will typically either call a service provider or contact the service provider through other means, such as through an Internet access, and the service provider will either transmit a new license to the wireless device or transmit a new application that has a new license embedded within it. Thus, significant action must be undertaken by the user, such as contacting the service provider from the wireless device, which can be expensive, or waiting until a less expensive connection can be made, such as from a land-based telephone line or an Internet connection.
Accordingly, it would be advantageous to provide a system whereby a licensed software application can have its license renewed without significant action taken by the user of the wireless device to contact the software application provider. Further, such license should be readily integrated into the wireless device and software application so that a significant update or reload of the application is not necessary in order to use the new license. It is thus to the provision of such a system and method that can control the licensing of the software applications on wireless devices that the present invention is primarily directed.
The present invention is a system and method for controlling software applications on one or more wireless devices where each wireless device is in selective communication with one or more application managing servers over a wireless network, such as a cellular telecommunications network or a wireless WAN or LAN. Each wireless device has one or more selectively executable resident software applications that require a valid license for each execution of the application. Upon the attempted execution of a software application either automatically or at the direction of the user of the wireless device, the wireless device determines if a license is present. If a license is not present, the wireless device selectively prompts, either automatically or at the direction of the user, the application managing server for transmission of a license over the network, receives the license transmitted from the application managing server across the wireless network, and the wireless device installs the license such that the software application is again licensed and executable.
When the wireless device does not have a license for the execution of the software application, the wireless device can prompt the user of the wireless device to obtain the requisite license for execution of the software application. If authorized to obtain the requisite license, the wireless device will then bridge a communication link to the application managing server in order to prompt the application managing server to transmit the requisite license. The user will likely be charged for the license to execute the application, and the charging can occur at the time of obtaining the new license, such as purchase with a credit card number or other electronic funds transfer (EFT) method, or the application managing server can maintain the record for the download of the license and bill the user within the normal accounting cycle for use of the wireless device.
The application managing server can have only application license related data or the server can also selectively download entire software applications along with the requisite license to the wireless device over the wireless network. Because the server can have varying degrees of functionality and interface with one or more databases and other servers, the application managing server can also be the entire interface of the wireless device with the wireless network and provide all services to the wireless device. Thus, the application managing server is readily scalable.
There are several methods that the wireless device can utilize to determine if a license is present depending upon if the license is maintained at the wireless device or on an application managing server. If the application managing server stores the license for execution of a specific software application on a specific wireless device, upon the attempted execution of a software application on that wireless device, the wireless device will selectively prompt the application managing server for transmission of a singular license or a copy of a license maintained at the application managing server side. Otherwise the wireless device stores the license for execution of a specific software application, and the wireless device will determine if the license has expired.
The software application license can be of a finite duration such that a new license must be periodically obtained for continual usage of the software application. The license can thus expire based upon a fixed-durational criteria, such as on a fixed date, after a predetermined number of executions of the software application on the wireless device, after the elapse of a predetermined duration since the software application was downloaded to the wireless device, or after a predetermined duration of usage of the software application.
The present invention therefore includes a method for controlling software applications on one or more wireless devices, and the steps of the method can occur at the direction of a computer program executing on the computer platform of the wireless device. The inventive method includes the steps of attempting to execute a software application upon a wireless device, and determining if a license is present for the wireless device to execute the software application. If a license is not present, then the method includes the steps of selectively prompting the application managing server from the wireless device for transmission of a license, selectively transmitting a license from the application managing server to the wireless device, receiving the transmitted license at the wireless device, and installing the license on the wireless device such that the licensed software application is executable. The method also preferably includes the step of, upon the attempted execution of a software application for which a license is not present, prompting the user of the wireless device to obtain the requisite license for execution of the software application.
The step of determining if a license is present for the wireless device to execute the software application can be determining at the wireless device if a license is present to execute the software application, or determining at the application managing server if a license is present for the wireless device to execute the software application. Further, depending on the type of license present, the step of determining if a license is present for the wireless device to execute the software application can be determining if the license has expired based upon expiration on a fixed date, determining if the license has expired based upon a predetermined number of executions of the software application having occurred on the wireless device, determining if the license has expired after the elapse of a predetermined duration since the software application was downloaded to the wireless device, or determining if the license has expired after the elapse of a predetermined duration of usage of the software application. And dependent upon the manner in which the license is held within the system, i.e. on the wireless device or the application managing server, the step of selectively transmitting a license from the application managing server to the wireless device can be selectively transmitting a copy of a license for the software application of the wireless device held at the application managing server.
It is therefore the primary object of the present invention to provide a system and method to selectively license software applications on wireless devices that can renew the license across the wireless network through the prompting of an application managing server to transmit the requisite license. The transmitted license is readily integrated into the software application on the wireless device so that a significant update or reload of the software application is not necessary in order to use the new license. The present invention thus provides an advantage to the user of the wireless device in that the user can easily and quickly update the licenses for resident software applications without having to either call or contact the service provider for transmission or installation of the license.
Other objects, advantages, and features of the present invention will become apparent after review of the hereinafter set forth Brief Description of the Drawings, Detailed Description of the Invention, and the Claims.
With reference to the figures in which like numerals represent like elements throughout,
The application managing server 16 is shown here on a local server-side network 26 with other computer elements in communication with the wireless network 14. There is a second server 30 and a stand-alone server 32, and each server can provide separate services and processes to the wireless devices 12,18,20,22 across the wireless network 14. There is preferably also at least one data store 28 containing stored-application related data includes the records for the specific applications downloaded by specific wireless devices 12,18,20,22, and the licenses and/or license status of the software applications, as is more clearly shown in
In
The wireless device, such as cellular telephone 12, has a computer platform 50 that can receive and execute software applications transmitted from the application download server 16. The computer platform 50 includes an application-specific integrated circuit (“ASIC”) 52, or other processor, microprocessor, logic circuit, or other data processing device. The ASIC 52 is installed at the time of manufacture of the wireless device and is not normally upgradeable. The ASIC 52 or other processor executes the application programming interface (“API”) layer that interfaces with any resident programs in the memory 56 of the wireless device. The memory can be comprised of read-only or random-access memory (RAM and ROM), EPROM, EEPROM, flash cards, or any memory common to computer platforms. The computer platform 50 also includes a local database 58 that can hold applications not actively used in memory 56, as well as license information for the software applications. The local database 58 is typically a flash memory cell, but can be any secondary or tertiary storage device as known in the art, such as magnetic media, EPROM, EEPROM, optical media, tape, or soft or hard disk.
The wireless device, such as cellular telephone 12, accordingly downloads one or more software applications, such as games, news, sports data, stock monitors, and the like, with their associated licenses and holds the applications and licenses on the local database 58 when not in use. The actual license for the particular software application can be copied to the wireless device from the application managing server 16 with the software, or the license can be created on the wireless device as a file, key, other resident object, or in any manner known in the art. When the wireless device uploads stored resident applications from the local database 58 to memory 56 for execution on the API 54 when so desired by the user, the wireless device 12,18,20,22 will check the license associated with the specific application and if the license is no longer valid, then the wireless device will not execute that software application until a new license is downloaded to the computer platform 50 and is associated with the software application.
The system 10 controls the software applications on one or more wireless devices 12,18,20,22 through the provision of the licenses to the wireless devices across the wireless network 14. As each wireless device 12,18,20,22 can selectively communicate with one or more application managing servers 16,30, upon the attempted execution of a software application on the wireless device 12,18,20,22 for which a license is not present, the wireless device selectively prompts the application managing server 16,30 for transmission of a license, receives the transmitted license, and installs the license on the wireless device such that the licensed software application can be executed. It should be noted that the application managing server 16 prompted by the wireless device does not need to be the server actually sending the license to the wireless device. In such instance, the application managing server 16 can direct another server, such as server 30 to send the license to the wireless device, and have another server, such as server 32, keep the records of the software application download. In such manner, a distributed server-side network can manage the software applications and provide the licenses to the wireless devices 12,18,20,22 of the system 10.
In one embodiment, the wireless device 12,18,20,22, upon the attempted execution of a software application for which a license is not present, prompts the user of the wireless device to obtain the requisite license for execution of the software application, which would be necessary if the communication link to the wireless network 14 is billable to the user, such as a cellular telephone call. Otherwise, the prompting can occur automatically and the re-licensing process can occur transparently to the user.
The wireless device 12,18,20,22 typically stores the license for execution of a specific software application of the wireless device, preferably in the local database 58 of the computer platform 50 of the wireless device. Alternately, the application managing server 16 stores the license for execution of a specific software application on a specific wireless device 12,18,20,22 and upon the attempted execution of a software application on that wireless device, the wireless device selectively prompts the application managing server 16 for transmission of a copy of the license or a single execution license.
The license is typically of a finite duration so that the user will need to obtain additional licenses for extended use of a specific software application. An extant license on either the wireless device 12,18,20,22 or the application managing server 16 can expire based upon any criteria, such as expiration on a fixed date, after a predetermined number of executions of the software application on the wireless device (ex. 30 uses), after the elapse of a predetermined duration since the software application was downloaded to the wireless device, or after the elapse of a of predetermined duration of usage (ex. 30 minutes of execution). Other limiting criteria for software licenses as are known in the art are readily applicable to the license in the present invention as would be apparent to one of skill in the art.
One example of the storage and the application-related data is shown in
In
If a license is not present at decision 92, then the wireless device 12,18,20,22 prompts the user to obtain a new license in order to execute the application, as shown at step 96, and determines whether the user authorized the retrieval of a new license, as shown at decision 98. If the user did not authorize the retrieval of the license, then the wireless device informs the user that application cannot be executed without a valid license, as shown at step 100, and the execution process terminates. Otherwise, if the user authorizes the retrieval of the license, then the wireless device prompts the application managing server 16 to transmit a new license for the software application, as shown at step 102. If the method is automated to obtain the new license, then the method does not include step 96, decision 98, and step 100. Once the application managing server 16 receives the prompt from the wireless device, the server 16 will send the license unless other criteria are required for transmission of the license, such as a credit card number or EFT number, or the existence of a valid account to which the cost for the downloaded license can be billed.
A determination is then made as to whether the application managing server 16 has sent the valid license, as shown at decision 104, and if not, the user is informed of the failure of the application managing server 16 to transmit the license, as shown at step 106, and then the execution process is terminated. If the license has been transmitted from the application managing server at step 104, then the wireless device receives and verifies receipt of the transmitted license, as shown at step 108, and installs the license on the wireless device, and preferably into the software application or at least associated therewith, such that the licensed software application can be executed. The transmission of the license can be the transmission of a full copy of a license, a partial copy of a license, a key, or other object that can update an existing license file or create a new license file for the software application on the wireless device 12,18,20,22. Once the new license is received (and a new license file created if so embodied), the now-licensed software application is then executed, as shown at step 112, and then the execution process terminates.
If the system 10 is intended to automatically retrieve the new license, then the user is only prompted of the failure of retrieval of the new licenses, such as at steps 100 and 106. Otherwise, the steps of the method can be executed and the new license obtained transparently to the user, and depending upon the speed of the network, wireless device computer platform 50, and the application managing server 16, the retrieval and installation can have an imperceptible duration.
In the embodiment of
In view of the inventive method, the present invention includes a program resident in a computer readable medium, where the program directs a wireless device having a computer platform to perform the inventive steps of the method. The computer readable medium can be the memory 56 of the computer platform 50 of the cellular telephone 12, or other wireless device, or can be in a local database, such as local database 58 of the cellular telephone 12. Further, the computer readable medium can be in a secondary storage media that is loadable onto a wireless device computer platform, such as a magnetic disk or tape, optical disk, hard disk, flash memory, or other storage media as is known in the art.
