Embodiment Construction

[0061] figure 2 It is a schematic flowchart of a method for a user equipment with a SIM card to access an evolved network according to an embodiment of the present invention. like figure 2 As shown, this embodiment describes how the mobile management entity (MME) authenticates the UE according to the four-tuple authentication vector (Authentication Vector, referred to as AV) generated by the HSS when the SIM card user equipment accesses the evolved network, including the following steps:

[0062] Step 201, receiving the four-tuple AV corresponding to the SIM card user equipment generated by the Home Subscriber Server (HSS), the four-tuple AV including the random number RAND and the expected challenge response XRES;

[0063] Four-tuple AV also includes: authentication parameter (AUTN) and root key (Kasme);

[0064] The MME can subsequently generate a Non-Access Signaling (NAS) encryption key and a NAS integrity protection key according to the Kasme in the quadruple AV;

Abstract

The embodiment of the invention relates to a method and a related device for accessing SIM card user equipment to an evolution network. The method comprises the following steps: receiving a quadruple authentication vector (AV) which is generated by a home subscriber server (HSS), corresponds to the SIM card user equipment and comprises random number and expected challenge response; sending authentication request message which comprises the random number in the quadruple AV to the SIM card user equipment; receiving user end challenge response generated by the SIM card user equipment according to the random number in the quadruple AV; and if the received expected challenge response in the quadruple AV and the user end challenge response are consistent, achieving successful authentication. Therefore, the SIM card user equipment can be added into the evolution network, or shifted into the evolution network from other networks, or shifted out from the evolution network; and the method and the related device ensure that an SIM card user can be accessed to the evolution network.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method for SIM card user equipment to access an evolution network and related equipment. Background technique [0002] The existing 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP for short) wireless network is divided into two parts: a 3GPP radio access network and a core network. Among them, the 3GPP radio access network is divided into three types: ①Global System for Mobile Communications (Global System for Mobile Communications, referred to as GSM) edge radio access network (GSM / EDGE Radio AccessNetwork, referred to as GERAN), the GERAN is a 2G access network, It includes Base Transceiver Station (BTS for short) and Base Station Controller (BSC); ②Universal Terrestrial Radio Access (UTRAN for short), which is a 3G access network. Including a base station (Node B, referred to as NodeB) and a radio network controller (Radio N...
