DETAILED DESCRIPTION

[0031] In the figures, same elements and elements having the same function are equipped with the same reference signs.

[0032] FIG. 1 shows in a schematic view an embodiment of a multimedia system 10 for a motor vehicle 12. The multimedia system 10 comprises at least a cloud server 14 (FIG. 2) and a multimedia device 16 (FIG. 2). In FIG. 1 the motor vehicle 12 can have a connection to a third party application authentication server 18. Furthermore, the third party application authentication server 18 can have a connection to a user setting 20 for the mobile device 16 from a user.

[0033] FIG. 1 shows a method for operating the multimedia system 10 for the motor vehicle 12, wherein a first mobile network connection 22 (FIG. 2) is established between the cloud server 14 of the multimedia system 10 external to the motor vehicle 12 and the multimedia device 26 of the multimedia system 10 internal to the motor vehicle 12 and wherein a second mobile network connection 24 (FIG. 2) is established between the cloud server 14 and a mobile device 16.

[0034] At least the user setting 20 for the mobile device 16 from the user is transferred from the mobile device 16 to the cloud server 14 by using the second mobile network connection 24 and this at least one user setting 20 is stored at the cloud server 14, so that the multimedia device 26 can directly access this user setting 20 by just using the first mobile network connection 22, in particular without any connection to the mobile device 16.

[0035] In particular, the multimedia device 26 is using the at least one user setting 20, wherein the mobile device 16 is disconnected to the cloud server 14. In particular, the at least one user setting 20 can be used by the user by operating of the multimedia device 26, for example, if the multimedia device 26 is built as a touchscreen.

[0036] In other words, FIG. 1 shows that the goal of the invention is to store a user information, which is in particular the user setting 20, in such a way as to be simple, computation efficient, and user-friendly enough to facilitate a personalized ecosystem based on individual user preferences. The solution presented here is a methodology of uploading user device/smartphone settings to the motor vehicle's 12 hosted services that are facilitated by the cloud server 14 connected multimedia device 26 with the ability to take the function of the mobile device 16. Here, the user setting 20 contains information such as data, texts/calls, and applications. In other words, the at least one user setting 20 is used for a phone call, a message service, mobile device 26 applications, and/or data of the mobile device 16.

[0037] The first mobile network connection 22 and/or the second mobile network connection 24 can be a service of either wireless LAN or a cellular provider service.

[0038] It is shown that the mobile device 16 can be a smartphone. It is also possible that the mobile device 16 can be a tablet or any other user device that could run the user application as further described as the smartphone and can equally be a computerized platform or an IoT device that can be connected to the cloud server 14.

[0039] To use this smartphone application directly via the multimedia device 26, the user must agree to such use and provide credentials 36 (FIG. 6) for each application on the vehicle. The motor vehicle 12 will safely provide credentials 36 on its private server for future use. Note that the user will choose individual applications and add credentials 36 for each newly added application. Credentials 36 for an application need to be provided only once, the user will then be able to access the chosen application without reentering credentials 36. Credentials 36 are a trusted form of established user identification.

[0040] In this context, there is no need to connect or open the application on the smartphone, instead the user will interact with the application via the vehicle user interface. The application will be automatically updated by the application's authentication server. For example, a user is accessing the third party application authentication server 18 on the headunit to make a change. The third party application authentication server 18 will remember that change. When the user accesses the third party application authentication server 18 on the smartphone, the change is already made.

[0041] FIG. 2 shows a schematic view of the multimedia system 10. FIG. 2 shows especially that the multimedia device 26 and the mobile device 16 can be synchronized by the cloud server 14. For example, a cloud storage is needed to synchronize the applications a user has chosen to use the motor vehicle's 12 headunit. Here, a cloud storage contains profiled data in key/value pairs for the application state. The user stores profile data in application states on the cloud storage. Here, for example, a bucket is created to store user data, where the data can be viewed or moved at any time. When the data is removed, the bucket that contains the data can be deleted. The user can then synchronize the data in the cloud server 14 with data on the motor vehicle 12. A service provides a local cache 28 for data to allow applications to read and write data without connectivity. When the mobile device 16 is connected, data in the local cache 28 will synchronize to the cloud server 14 and notify the multimedia device 26 when an update is available. When the headunit, which is the multimedia device 26, is turned on, the user can download content from the cloud storage to the motor vehicle 12. This is equally applicable to stored files, such as photos, videos, or documents. The user is able to access on the motor vehicle 12 the same personal applications as installed on the mobile device 16.

[0042] Furthermore, FIG. 2 shows that at least one credential 36 for using the user setting 20 is submitting by operating the multimedia device 26. In particular, the at least one credential 36 is stored by the multimedia device 26. Once the vehicle is configured with the information of the applications that now run on the motor vehicle 12 and the relevant preferences, a user had set up on the mobile device 16, the user can then access these applications directly on the motor vehicle 12. In general, a user is required to provide credentials 36 for individual applications. To avoid the need of entering credentials 36 for each application every time the application is accessed, the user credentials 36 may be stored in the multimedia device 26. A script can be implemented on the multimedia device 26 to store the credentials 36. Here, a user needs to provide the credentials 36 for the first attempted to access this application on the vehicle's headunit. Once, a successful access has been granted, the credentials 36 may be stored in a script. Accordingly, a subsequent use of the application on the vehicle's headunit will not prompt the user to provide credentials 36, as the script will inject a stored login form, fetch and hash the credentials 36, and send it to the application's authentication server for log in. Note the script should use local state of the art encryption or remote service. Furthermore, it is possible that software running in the background of the multimedia device 26 will need to detect when the user is launching an application requiring credentials 36 and whether it is a new application from a previously defined template. The software will then fetch the previously saved credentials 36 on the motor vehicle's 12 headunit and submit the credentials 36 for user. The software needs to be installed and maintain on the vehicle's headunit where applications are launched.

[0043] FIG. 3 shows another schematic view of the multimedia system 10. FIG. 3 shows that an application of the authentication process from the multimedia device 26 to an authentication server 30 can be done. In a first step S1, the user opens the application, for example, third party application, on the multimedia device 26 that then sends access requests to the application server. In a second step S2, the application server then sends an application form back for the user to complete. In a third step S3, if it is first time access to the application, the user is required to fill out the form with credentials 36 and then return to the application server by the multimedia device 26. In a fourth step S4, the application server sends the credentials 36 to its authentication data base 30 for verification. In a fifth step S5, once authenticated, the application server grants the user access to the web page and the multimedia device 26 may store the user ID and password in the multimedia device 26 credential 36 database if so chosen. If the application URL has been successfully accessed, the multimedia device 26 will, if enables to do the step S3, and then send the user ID and password from the credential 36 data base to the application server 13.

[0044] FIG. 4 shows in another schematic view an embodiment of the multimedia system 10. FIG. 4 shows how a user can text a message or make a phone call in the motor vehicle 12. The user will be able to access text messages and calls on the multimedia device 26 directly through, for example, wireless LAN connection with a wireless communication service provider. Here, there is no need to synchronize calls or messages because the mobile carrier will update the mobile device 16 simultaneously when a text or call is made. The developer may create an application on the multimedia device 26 that registers a user's smartphone number and allows to send or receive calls and text messages. The flow of how the vehicle's headunit sends text message via WLAN and how the mobile provider updates the smartphone remotely is shown in FIG. 4. First, the multimedia device 26 sends an HTTP-request to a text message gateway 32. The text massage gateway 32 connects to the network cloud using text protocols. Once, the cloud server 14 receives the text protocols, it sends the data to a mobile carrier's SMSC 34. The mobile carrier updates the smartphone 16 base station controller.

[0045] FIG. 5 shows in a schematic view another embodiment of the multimedia system 10. In FIG. 5 it is shown that an offline work with the mobile device 16 and/or the multimedia device 26 is stored and after a connection from the mobile device 16 and/or the multimedia device 26, the cloud server 14, the mobile device 16 and the multimedia device 26 are synchronized. In particular, it is shown a user data synchronization by updating the multimedia device 26 from the cloud server 14. For example, a user can synchronize their smart devices and the vehicle remotely using the cloud server 14. By using cloud server 14, user can store their data, preferences, states and update their devices or the multimedia device 26 after login. A user is able to work offline and store the changes in local data base first when there is no connectivity and update later when the connectivity is back.

[0046] FIG. 6 shows in another schematic view a multimedia system 10. Particularly, FIG. 6 shows a cloud hosted service structure. Overall, the cloud server 14 serves as a communication support for the user to be able to access smart device applications locally from the multimedia device 26. The cloud server 14 may store user data, manage credentials 36, and send/receive updates from both the multimedia device 26 and the mobile device 16. The extent of the application processing and load share between the multimedia device 26 and the cloud server 14 depends on infrastructure and bandwidth and can range from having just a user interface on the multimedia device 26 while running the application on a cloud-based service to run the application directly on the multimedia device 26. FIG. 6 shows who the cloud could connect with, the multimedia device 26 using, for example, REST IPs, messages 38, data 40 and credentials 36 using HTTPs. A user may REST IPs to access application 42 to receive or send data. User uses HTTPs to call or send messages 38.

[0047] The invention shown in FIGS. 1 to 6 also relates to a computer program comprising instructions, which, when the program is executed by the multimedia device 10, cause the multimedia system 10 to carry out the method.

[0048] This realization comes with the benefit of being able to utilize existing technologies for connectivity, security, and cloud infrastructures from service providers. For example, the user will not need to bring and connect the mobile device 16 every time to the multimedia device 26.

[0049] All in all, FIG. 1 to FIG. 6 show a cloud hosted smartphone and other IoT applications.
