摘要

A data transmission method includes calculating, by a user equipment (UE), a first message authentication code of first location privacy setting data, sending, by the UE, the first message authentication code and the first location privacy setting data to a data management network element, receiving, by the UE, a second message authentication code from the data management network element, calculating, by the UE, a third message authentication code of the first location privacy setting data, determining, by the UE, that the first location privacy setting data is not tampered with when the second message authentication code is the same as the third message authentication code.

說明書

Step S112a: The H-GMLC sends the third message authentication code to the V-GMLC. Correspondingly, the V-GMLC receives the third message authentication code from the H-GMLC.

Step S113a: The V-GMLC sends the third message authentication code to the LMF. Correspondingly, the LMF receives the third message authentication code from the V-GMLC.

Step S114a: The LMF sends the third message authentication code to the AMF. Correspondingly, the AMF receives the third message authentication code from the LMF.

Step S115a: The AMF sends the third message authentication code to the UE. Correspondingly, the UE receives the third message authentication code from the LMF.

Step S116a: The UE calculates a fourth message authentication code of the first location privacy setting data, and determines whether the third message authentication code is the same as the fourth message authentication code.
