Patent Application
20110246547
1. Field
The present application relates generally to the operation of wireless communication systems, and more particularly, to methods and apparatus for device applet management on smart cards.
2. Background
Applications (Apps) or device applets, are now available that can be used to provide a wide range of add-on services and features to portable devices. For example, it is now possible for portable devices to download and launch device applets to perform value added functions such as, shopping, searching, position location, providing driving directions or an array of other functions. Carriers and service providers generally offer these device applets to device users for additional fees. Thus, the use of device applets increases the functionality and usability of portable devices and offers device users features and convenience not originally available on the devices themselves.
Currently, when the user downloads device applets to a device having a smart card, e.g. Removable User Identity Module (R-UIM) or CDMA Subscriber Identify Module (CSIM), those device applets are typically stored in device memory and are bound to that device. When the user removes the R-UIM/CSIM from the device and plugs it into a new device, all the device applets downloaded earlier are not available in the new device. When the user tries to download the device applets again, the user may need to pay for those device applets again since the application billing server cannot handle this scenario (e.g. the card on the new device is recognized as a totally different user). Furthermore, when the user plugs in a different card to the same device and then downloads new device applets, conflicts between the existing device applets and the newly downloaded device applets arise due to limitations of various device applet storage implementations
Therefore, it would be desirable to have a mechanism that operates to allow device applets to be stored on a smart card in such a way as to overcome the problems associated with conventional systems as described above.

Other aspects will become apparent after review of the hereinafter set forth Brief Description of the Drawings, Description, and the Claims.
The foregoing aspects described herein will become more readily apparent by reference to the following Description when taken in conjunction with the accompanying drawings wherein:
The following description describes implementations of a device applet management system that operates to allow device applets to be stored on a smart card such that the stored device applets can be launched from any device that is in communication with the smart card. For example, the system operates to allow device applets downloaded to a first device to be stored on a smart card for later execution on a second device. The system is especially well suited for use with mobile devices, but may be used with any type of device.
In various implementations, the device applet management system operates to provide one or more of the following functions.
a. Operator provisioning/configuration
b. User preferences/configuration
c. Device applets
The devices 104 and 106 comprise mobile telephones, PDAs, notebook computers, pagers, email devices, or any other type of device that is operable to communicate with the network 112. The device 104 is in communication with the network 112 via wireless communication link 118, which allows data, voice or other information to be wirelessly transmitted between the network 112 and the device 104. The wireless communication link 118 comprises forward communication channels, reverse communication channels, paging channels, control channels, broadcast/multicast channels and any other type of communication channel that may be used to communicate information between the network 112 and the device 104.
The device 104 comprises the device applet management apparatus 110 which is in communication with the smart cart 108. For example, the smart card 108 is installed into the device 104 so that the device applet management apparatus 110 can store and retrieve information to/from the smart card 108.
During operation of the device applet management system, device applets downloaded to the device 104 are stored in the smart card 108 utilizing a directory structure generated by the device applet management system. For example, device applets downloaded from the device applet download server 102 are received at the device 104 and the device applet management apparatus 110 operates to format the device applets into the directory structure to store these device applets on the smart card 108. In one implementation, the device applets comprise downloaded device applets 114 or preloaded device applets 116.
In various implementations, the device applet management apparatus 110 operates to store device applets on a smart card, such as a Universal Integrated Circuit Card (UICC) by creating new a DF-Device_applets (dedicated file device applets) directory that comprises elementary files (EFs) under the CDMA2000 Subscriber Identify Module (CSIM) Application Definition File (ADF) structure. The new DF-Device_applets directory is created to store device applets such that they are ‘global’ in nature in that they can be run in both CDMA and GSM/UMTS modes. Device applets specific to CDMA or GSM/UMTS are allowed as well. In addition, each device applet has an attribute to indicate the platform it is intended for (i.e., Java, WinMobile, BREW, Google Android, etc.).
The contents in the DF-Device_applets directory are protected by card holder verification (CHV) or PIN (Personal Identification Number) for read and write access, except for operator pre-loaded device applets which are read-only (write access is protected). Per operator's choice, a device applet can be protected by CHV/PIN for read access, or it can be made available without CHV/PIN verification so that the device applet can be read anytime. Once the device applets have been stored on the smart card 108 by the device applet management apparatus 110, the smart card may be installed into the device 106 and the stored device applets will be available on that device.
Device 106 comprises the device applet management apparatus 120 which establishes communication with the smart card 108 after it is installed. The device applet management apparatus 120 is operable to read the directory structure of the smart card 108 and provide the user with a listing of available device applets (both downloaded 114 and preloaded 116). One or more device applets can then be selected by the device user for execution.
Therefore, in various implementations, a device applet management system is provided that operates to store downloaded and preloaded device applets on a smart card using a directory structure provided by the device applet management system. The smart card can be installed into other devices and the stored device applets will become available to those other devices. Thus, the system eliminates the requirement to re-download or re-purchase device applets acquired on a first device; so that those device applets can be used on a second device. It should be noted that the communication network 100 illustrates just one implementation and that other implementations of the device applet management system are possible.
The transceiver 208 comprises hardware and/or hardware executing software that operates to allow the device applet management apparatus 200 to communicate data or other information over a communication link 212 with remote devices or systems. For example, the transceiver 208 is operable to receive device applets, device information, or other information from network servers, (such as the server 102 shown in
The local memory 204 comprises RAM, ROM, EEPROM or any other type of memory device that operates to allow information to be stored and retrieved at a device. The memory 204 is operable to store information such as user profiles, device applets, directories and/or any other type of information. Information stored in the memory 204 is accessible to other functions of device applet management apparatus 200 using the bus 210. The memory 204 comprises a device applet management program 224 that can be executed by the processor 202 to provide the functions of the device applet management system.
The user interface 206 comprises at least one of a CPU, processor, gate array, hardware logic, memory elements, and/or hardware executing software. The user interface 206 operates to communicate with a device user to receive user input or to provide information to the device user through a device display. The user interface 206 typically operates under the control of the processor 202 but may also operate to provide user interaction with any other function at the device applet management apparatus 200.
A smart card 214 is shown that is coupled to the bus 210. For example, the smart card may be any type of UICC card. The smart card 214 can be installed into and removed from a device that includes the device applet management apparatus 200. When the smart card 214 is installed into the device, the smart card 214 is coupled to the bus 210 to allow communication with other functional elements of the device applet management apparatus 200. The smart card 214 is operable to store any type of device applet, program, data or other information. For example, the smart card 214 is operable to store preloaded device applets 218 and downloaded device applets 222.
The processor 202 comprises at least one of a CPU, processor, gate array, hardware logic, memory elements, and/or hardware executing software. The processor 202 operates to control the operation of the device applet management apparatus 200 so that device applets can be stored and retrieve from the smart card 214.
During operation, the processor 202 operates to control the transceiver 212 to download one or more device applets. The processor 202 then generates a directory structure (DIR-U) 220 which is stored with the downloaded device applets 222 on the smart card 214. The directory structure DIR-U 220 operates to “globalize” the downloaded device applets 222 so that they will be accessible to another device when the smart card is installed in that other device.
The processor 202 utilizes the local memory 204 as storage to allow downloaded device applets to be temporarily stored while the DIR-U 220 is created. The processor 202 may also obtain user inputs from the user interface 206 which operate to determine the device applets to download or provide other parameters that can affect the operation of system.
The processor 202 also operates to read operator preloaded device applets 218 from the smart card 214 and create another directory structure (DIR-O) 216 that is stored back on to the smart card 214 with the preloaded device applets 218. Thus, the preloaded device applets will also be “globalized” and accessible from the smart card 214 when installed on other devices.
In various implementations, the device applet management system comprises a computer program product having one or more program instructions (“instructions”) or sets of “codes” stored or embodied on a computer-readable medium. When the codes are executed by at least one processor, for instance, processor 202, their execution causes the processor 202 to provide the functions of the device applet management system described herein. For example, the computer-readable medium comprises a floppy disk, CDROM, memory card, FLASH memory device, RAM, ROM, or any other type of memory device or computer-readable medium that interfaces to the device applet management apparatus 200. In another aspect, the sets of codes may be downloaded into the device applet management apparatus 200 from an external device or communication network resource. The sets of codes, when executed, operate to provide aspects of the device applet management system described herein.
It should be note that other implementations are possible. For example, in the EF-Device applet Directory, a first level of information can comprise the Platform Type and a second level can comprise the Device applet List containing device applets for that platform type. There can be multiple instances of these two levels.
At block 402, a smart card is installed in a device that comprises the device applet management system. For example, the device may be device 104 shown in
At block 404, one or more device applets are obtained. In one implementation, the device applets are downloaded from a device applet download server using the transceiver 208. In another implementation, preloaded device applets are retrieved from the installed smart card. The obtained device applets are stored in the local memory 204.
At block 406, DF and EF directory structures are generated. For example, the processor 202 generates the directory structures shown in
In another implementation, the processor 202 uses space in DF-Device applets directory to store any application data either as part of the device applet or in a separate device applet memory space in the DF-Device applets directory (e.g. UI widgets, themes, screen savers, etc.) During operation, the processor 202 can run the device applets directly from the smart card and allows the user to add and delete user downloaded device applets on the smart card at any time.
In another implementation, the processor 202 configures the DF and EF directory structures so that multiple instances of a particular device applet are identified with multiple platform types, respectively. This allows the particular device applet to be accessed on the smart card by any device supporting at least one of the multiple platform types.
At block 408, the DF and EF directory structures and associated device applets are stored on the smart card. For example, the processor 202 stores the information to the smart card using the bus 210. In one implementation, the DF and EF directory structures are stored using a card holder verification (CHV) service and/or a personal identification number (PIN) service. In one implementation, one or more device applets in the directory structure are stored on a smart card so that when the smart card is in communication with a second device that supports a selected platform type, the corresponding device applets associated with the selected platform type are accessible to the second device.
Therefore, the method 400 is performed by a device applet management apparatus at a first device to store device applets on a smart card for later access by a second device. It should be noted that the method 400 is just one implementation and that the operations of the method 400 may be rearranged or otherwise modified such that other implementations are possible.
At block 502, access to a smart card is detected. For example, a UICC card is installed in a portable device, such as a mobile phone. The smart card comprises one or more device applets that were previously stored on the smart card using implementations of the device applet management system disclosed herein. Thus, the smart card comprises one or more device applets and associated information stored in a directory structure provided by the device applet management system as illustrated in
At block 504, a directory structure on the smart card is read so that device applets stored on the smart card can be identified. In one implementation, the processor 202 reads the directory structure from the smart card.
At block 506, device applets on the smart card that are associated with the current device platform are determined. In one implementation, the processor 202 is aware of the current device platform and analyzes the EF device applet directory and the EF operator device applet directory to determine device applets on the smart card that are associated with the current device platform.
At block 508, the device applets associated with the current device platform are presented to a device user. In one implementation, the processor 202 controls the user interface 206 to display these device applets to a device user. For example, the device comprises a display which is used to display device applets on the smart card available for use with the current device platform.
At block 510, a device user inputs device applet selection information to select one or more device applets to be launched. In one implementation, the device user communicates device applet selections using the user interface 206.
At block 512, the selected device applets are launched. In one implementation, the processor 202 retrieves the selected device applets from the smart card and launches those device applets. In one implementation, device applets on the smart card (either preloaded or downloaded) are freely provided by service providers as a value added service (e.g. Instant Messaging client), as a promotion of premier services. The device user can execute the free device applet to decide if the premier service if desired. If so, the free device applet operates to allow the device user to download the premier device applet. If the premier device applet is downloaded, it too will be stored on the smart card in accordance with the device applet management system described herein. Thus, the system allows a first device applet to provide access to one or more additional device applets based on user input.
Therefore, the method 500 is performed by a device applet management apparatus at a second device to access device applets on a smart card previously stored by a first device. It should be noted that the method 500 is just one implementation and that the operations of the method 500 may be rearranged or otherwise modified within the scope of the various aspects such that other implementations are possible.
The device applet management apparatus 600 comprises a first module comprising means (602) for obtaining one or more device applets, which in an aspect comprises the transceiver 208. The device applet management apparatus 600 also comprises a second module comprising means (604) for generating a directory structure that identifies one or more platform types, and for each platform type identifies corresponding device applets from the one or more device applets, which in an aspect comprises the processor 202. The device applet management apparatus 600 also comprises a third module comprising means (606) for storing the one or more device applets in the directory structure on a smart card so that when the smart card is in communication with a second device that supports a selected platform type, the corresponding device applets associated with the selected platform type are accessible to the second device, which in an aspect comprises the processor 202.

The device applet management apparatus 700 also comprises a third module comprising means (706) for determining from the directory structure one or more device applets associated with a selected platform type, which in an aspect comprises the processor 202. The device applet management apparatus 700 also comprises a fourth module comprising means (708) for providing access to the one or more device applets, which in an aspect comprises the user interface 206.
