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 S209: The UDM sends the second digital signature to the H-GMLC. Correspondingly, the H-GMLC receives the second digital signature from the UDM.

The UDM may send the second digital signature to the H-GMLC by using one message, and the message may be, for example, a Nudm_UECM_Update response.

Step S210: The H-GMLC sends the second digital signature to the V-GMLC. Correspondingly, the V-GMLC receives the second digital signature from the H-GMLC.

The H-GMLC may send the second digital signature to the V-GMLC by using one message, and the message may be, for example, a Ngmlc_UserPrivacy_Set response.

Step S211: The V-GMLC sends the second digital signature to the LMF. Correspondingly, the LMF receives the second digital signature from the V-GMLC.

The V-GMLC may send the second digital signature to the LMF by using one message, and the message may be, for example, a Ngmlc_UserPrivacy_Set response.

Step S212: The LMF sends the second digital signature to the AMF. Correspondingly, the AMF receives the second digital signature from the LMF.

The LMF may send the second digital signature to the AMF by using one message, and the message may be, for example, a Namf_Communication_N2 message notify.

Step S213: The AMF sends the second digital signature to the UE. Correspondingly, the UE receives the second digital signature from the LMF.

The AMF sends the second digital signature to the UE by using the RAN. The AMF may send the second digital signature to the UE by using one message, and the message may be, for example, a NAS transport message.
