Embodiment Construction
[0039] exist figure 1 In , a method for invoking a data stream from a server by an application implemented on a user terminal device is shown.
[0040] In this case, method 100 includes receiving 102 a request from the application to a server via a network access point arranged in the vehicle to establish a connection between the application and the server.
[0041] The method 100 also includes establishing 104 a first connection between the network access point and the application, and establishing 106 a second connection between the network access point and the server. Therefore, instead of a single connection, the data stream is called up from the server by means of two separate connections. By splitting into two separate connections, another degree of freedom for invoking data flow can be provided.
[0042] The method 100 also includes requesting and receiving 108 a first subset of the data stream from the server via the second connection via the network access point, an...

A method is provided for invoking a data stream from a server by an application implemented on a user terminal device. In this case, the method includes receiving, via a network access point arranged in the vehicle, a request from the application to the server to establish a connection between the application and the server. The method also includes establishing a first connection between the network access point and the application, and establishing a second connection between the network access point and the server. The method also includes requesting and receiving, by the network access point, a first subset of the data stream from the server via the second connection, and storing the first subset in a buffer memory of the network access point. The method also includes receiving, via the network access point, the application's request to the server to send the second subset of data streams to the application. Here, the first subset includes the second subset. The method also includes sending a second subset of the data stream from the buffer memory to the application via the first connection.
Description
technical field [0001] The present invention relates to the flow of data in vehicles. In particular, the invention relates to a method for invoking a data stream from a server. The invention also relates to a vehicle with a network access point. Background technique [0002] Digitization is also becoming more and more important in vehicles. A motor vehicle can be not only a vehicle for carrying people but also a vehicle for carrying goods. For example, a motor vehicle may be a passenger car, a truck, a motorcycle, or a tractor. In general, a motor vehicle can be understood as a device comprising an engine, a transmission and wheels. In addition to the availability of music or video streaming, vehicle users would also like the possibility of downloading data from the Internet to a user end device such as a smartphone, tablet or laptop. [0003] In order to be able to provide data services of the aforementioned type, a stable and high-speed connection to a cellular networ...
