Abstract

A data collection coordination function, DCCF, network node receives (1a) a request for data from a data consumer, determines (2) a data source for the requested data, verifies (3a, 3b) with a network node that the data consumer and the DCCF are authorized by the data source, receives (3b) a message container for the data consumer from the network node, the message container for the data consumer including a data encryption key K E and a data integrity key Ki, and receives (3 b ) a message container for the data source from the network node, the message container for the data source including the data encryption key K E and the data integrity key Ki. The DCCF network node transmits (4 a ) the message container for the data consumer to the data consumer and transmits (5) the message container for the data source to the data source.

Claims (31)

1 . A method performed by a Third Generation Partnership Project (3GPP) data collection coordination function (DCCF) network node, comprising:

receiving a request for data from a data consumer;

determining a data source for the requested data;

verifying with a network repository function (NRF) network node that the data consumer and the DCCF network node are authorized by the data source;

receiving a message container for the data consumer from the NRF network node, the message container for the data consumer including a data encryption key K E and a data integrity key K 1 ;

receiving a message container for the data source from the NRF network node, the message container for the data source including the data encryption key K E and the data integrity key K 1 ;

transmitting the message container for the data consumer to the data consumer; and

transmitting the message container for the data source to the data source.

2 . The method of claim 1 , further comprising:

transmitting a subscription request to the data source;

upon a triggering event, receiving data from the data source, wherein the data is protected by at least one of the data encryption key K E and the data integrity key K I ; and

transmitting the received data to the data consumer.

3 . The method of claim 1 , wherein the data encryption key K E and the data integrity key K 1 within the message container for the data consumer are encrypted using a public key of the data consumer.

4 . The method of claim 1 , wherein the data encryption key K E and the data integrity key K 1 within the message container for the data source are encrypted using a public key of the data source.

5 . The method of claim 1 , wherein the message container for the data consumer and the message container for the data source are each signed by a private key of the NRF network node.

6 . A Third Generation Partnership Project (3GPP) data collection coordination function (DCCF) network node, comprising:

processing circuitry and memory collectively configured to:

receive a request for data from a data consumer;

determine a data source for the requested data;

verify with a network repository function (NRF) network node that the data consumer and the DCCF network node are authorized by the data source;

receive a message container for the data consumer from the NRF network node, the message container for the data consumer including a data encryption key K E and a data integrity key K 1 ;

receive a message container for the data source from the NRF network node, the message container for the data source including the data encryption key K E and the data integrity key K 1 ;

transmit the message container for the data consumer to the data consumer; and

transmit the message container for the data source to the data source.

7 . The DCCF network node of claim 6 , wherein the processing circuitry and memory are further collectively configured to:

transmit a subscription request to the data source;

upon a triggering event, receive data from the data source, wherein the data is protected by at least one of the data encryption key K E and the data integrity key K I ; and

transmit the received data to the data consumer.

8 . The DCCF network node of claim 6 , wherein the data encryption key K E and the data integrity key K I within the message container for the data consumer are encrypted using a public key of the data consumer.

9 . The DCCF network node of claim 6 , wherein the data encryption key K E and the data integrity key K I within the message container for the data source are encrypted using a public key of the data source.

10 . The DCCF network node of claim 6 , wherein the message container for the data consumer and the message container for the data source are each signed by a private key of the network node.
