SERVICE PROVIDER NODE, A METHOD THEREIN, AND A COMPUTER PROGRAM PRODUCT

1 . A method in a service provider node for transmitting data packets relating to parts of a service to a communication device, wherein the service provider node and the communication device are communicatively connected over a communications network and comprised in a communications system, and wherein the method comprises:

receiving a signal, which signal comprises an identifier of the communication device requesting a service, an identifier of the requested service, and an agreement comprising information about a previously agreed part of the service; and

agreeing on an upcoming part of the service requested by the communication device, while transmitting data packets relating to the previously agreed part of the service to the communication device, wherein the data packets are transmitted in dependence of the received signal.

2 . The method of claim 1 , further comprising:

receiving compensation from a financial service provider node, wherein the compensation corresponds to a cost associated with one or more received signals.

3 . The method of claim 1 , wherein the agreeing on the upcoming part while transmitting the previously agreed part further comprises:

continuously agreeing on the upcoming part of the service; and

simultaneously transmitting data packets relating to the previously agreed part of the service to the communications device.

4 . The method of claim 1 , wherein the agreeing on the upcoming part of the service further comprises:

receiving a request for the upcoming part of the service from the communication device, which request comprises a selected variant of the upcoming part of the service.

5 . The method of claim 1 , wherein the agreeing on the upcoming part of the service further comprises:

receiving a request for the upcoming part of the service from the communication device;

presenting a cost for the requested upcoming part to the communication device; and

receiving an acceptance of the presented cost from the communication device.

6 . The method of claim 5 , wherein the cost for the requested upcoming part of the service varies in dependence of a quality of the requested upcoming part, a size of the requested upcoming part, a point in time for the requested upcoming part in relation to the total time for the service, and/or in dependence of a user of the communication device requesting the upcoming part.

7 . The method of claim 2 , wherein the receiving the signal further comprises:

receiving the signal from the communication device, and wherein the method further comprises:

transmitting one or more received signals to the financial service provider node.

8 . The method of claim 2 , wherein the receiving the signal further comprises:

receiving the signal from the financial service provider node, whereby the service provider node is guaranteed that the received signal is backed up by a monetary value.

9 . The method of claim 2 , wherein the received signal further comprises an identifier of the financial service provider node, an identifier of one or more previously received tokens and/or a digital signature generated based on the information comprised in the signal.

10 . The method of claim 1 , further comprising:

authenticating the communication device and establishing a secure communication with the communication device by

receiving, from the communication device, a digital certificate generated by a certification node, comprised in the communications system and communicatively connected to the communications network;

verifying the received digital certificate;

verifying that a user of the communication device is a correct owner of the digital certificate by running a challenge-response sequence; and

establishing a secure communication to the communication device.

11 . A service provider node for transmitting data packets relating to parts of a service to a communication device, wherein the service provider node, and the communication device are communicatively connected over a communications network and comprised in a communications system, and wherein the service provider comprises:

a receiving circuit configured to receive a signal, which signal comprises an identifier of a communication device requesting a service, an identifier of the requested service, and an agreement comprising information about a previously agreed part of the service; and

an agreeing circuit configured to agree on an upcoming part of the service requested by the communication device, while a transmitting circuit comprised in the service provider node transmits data packets relating to the previously agreed part of the service to the communication device in dependence of the received signal.

12 . The service provider node of claim 11 , wherein the receiving circuit further is configured to receive a compensation from a financial service provider node connected to the communications network and comprised in the communications system, wherein the compensation corresponds to a cost associated with one or more received signals.

13 . The service provider node of claim 11 , wherein the agreeing circuit further is configured to continuously agree on an upcoming part of the service; and wherein the transmitting circuit is configured to simultaneously transmit data packets relating to the previously agreed part of the service to the communication device.

14 . The service provider node of claim 11 , wherein the agreeing circuit further is configured to:

receive a request for the upcoming part of the service from the communication device, which request comprises a selected variant of the upcoming part of the service.

15 . The service provider node of claim 11 , wherein the agreeing circuit further is configured to:

receive a request for the upcoming part of the service from the communication device ( 192 );

present a cost for the requested upcoming part to the communication device and

receive an acceptance of the presented cost from the communication device.

16 . The service provider node of claim 15 , wherein the cost for the requested upcoming part of the service varies in dependence of a quality of the requested upcoming part, a point in time for the requested upcoming part in relation to the total time for the service, and/or in dependence of a user of the communication device requesting the upcoming part.

17 . The service provider node of claim 12 , wherein the receiving circuit further is configured to:

receive the signal from the communication device, and wherein the transmitting circuit further is configured to:

transmit one or more received signals to the financial service provider node.

18 . The service provider node of claim 12 , wherein the receiving circuit further is configured to:

receive the signal from the financial service provider node, whereby the service provider node is guaranteed that the received signal is backed up by a monetary value.

19 . The service provider node of claim 12 , wherein the received signal further comprises an identifier of the financial service provider node, an identifier of one or more previously received signal and/or a digital signature generated based on the information comprised in the signal.

20 . The service provider node of claim 11 , further comprising:

an authenticating and establishing circuit configured to authenticate the communication device and to establish a secure communication with the communication device by

receiving, from the communication device a digital certificate generated by a certification node comprised in the communications system and communicatively connected to the communications network;

verifying the received digital certificate;

verifying that a user of the communication device is a correct owner of the digital certificate by running a challenge-response sequence; and

establishing the secure communication to the communication device.

21 . A computer program product for providing data packets relating to parts of a service to a communication device, wherein the computer program product is loadable into a memory of a computerized device and comprises software code portions adapted to perform one or more of the actions of claim 1 .
