LTE network access method, system and apparatus

Abstract

The invention discloses an LTE network access method, system and apparatus. The method comprises: a terminal and a network side storing an IMEI, an IMSI, a secret key K, a corresponding relation, and a registration password PIN; the terminal and the network side performing IMSI authentication; after the IMSI authentication succeeds, the network side performing AUC authentication; after the AUC authentication succeeds, the network side performing registration password PIN verification; and after the registration password PIN verification succeeds, the terminal being successfully accessed to an LTE network. According to the technical scheme provided by the invention, since an entity SIM card or an entity USIM card is unnecessary, the terminal can be accessed to the LTE network through a soft USIM mode, thus the SIM module and entity can be saved, and the terminal can be lighter and thinner. At the same time, terminal and network bidirectional authentication is employed, soft USIM registration and IMEI authentication are added, and other security mechanisms such as registration password PIN configuration by a user and the like are adopted, so that communication and authentication between a soft USIM terminal and a network can be realized, thus user and network security is ensured.

Description

technical field [0001] The present invention relates to the technical field of LTE, in particular to a method, system and device for accessing an LTE network. Background technique [0002] For the mobile terminal, the authentication process is carried out between the network and the SIM card, and the authentication time is generally when the mobile terminal registers to the network and makes a call. At the beginning of the authentication, the network generates a 128-bit random number RAND, which is transmitted to the mobile station through the wireless channel (control channel). The SIM card calculates the response signal SRES to the received RAND according to the key Ki in the card and the algorithm A3 , and send the result back to the network side. And the network end finds out the key Ki of the user at the authentication center, uses the same RAND and algorithm A3 to calculate the SRES, and compares it with the received SRES, if they are consistent, the authentication pa...

Problems solved by technology

[0005] In order to solve the technical problem of requiring a SIM card or USIM card entity in the authentication process existing in the prior art, the present invention proposes a method, system and device for accessing an LTE network, which may not use a physical SIM card or USIM card, but Use a soft USIM terminal to save SIM card or USIM card modules and entities, making the terminal thinner and lighter
