Embodiment Construction

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the drawings in the embodiments of the present disclosure.

[0048] In the present disclosure, "first", "second", "third", and "fourth" are used to distinguish different objects, and are not used to indicate meanings such as size or timing.

[0049] figure 1 It is a schematic diagram of the network structure of the present disclosure.

[0050] figure 1A GSM / WCDMA network and an LTE network are shown. In the GSM / WCDMA network, the terminal performs SQN authentication to the HLR. In the LTE network, the terminal performs SQN authentication to the HSS. In this disclosure, the network types are classified according to the HLR or HSS involved in the SQN authentication, that is, the GSM / WCDMA network belongs to the first network type, and the LTE network belongs to another different second network type. In the GSM / WCDMA network, the te...

Abstract

The invention provides an authentication method, device and system, and relates to the field of mobile communication. In the present disclosure, HLR and HSS respectively and independently generate SQNof a network side. A terminal generates SQNs of a terminal side for different networks respectively. When the terminal carries out authentication in each network, the authentication is carried out. An authentication result is judged by utilizing the consistency of the SQN of the network side corresponding to the network and the SQN of the terminal side. The problem of authentication failure caused by inconsistency of the SQN of the network side and the SQN of the terminal side due to the fact that the terminal performs authentication in different networks in sequence in a service scene in which the HLR and the HSS are deployed independently is solved.

Description

technical field [0001] The present disclosure relates to the field of mobile communication, in particular to an authentication method, device and system. Background technique [0002] AKA (Authentication and KeyAgreement, authentication and key agreement) authentication, one of the authentication parameters is the serial number (SQN). SQN is composed of sequence number array value (SEQ) and index number (IND), that is, SQN=SEQ||IND, and "||" means concatenation. For each authentication of the terminal, the SEQ on the terminal side and the SEQ on the network side will increase by one. [0003] In the authentication process of the GSM / WCDMA network, the terminal receives the SQN sent by the HLR (Home Location Register) on the network side, uses the IND in the SQN on the network side to search for the corresponding SEQ in the local SQN of the terminal, if the same The SEQ on the network side corresponding to the IND is consistent with the local SEQ of the terminal, and the a...
