Problems solved by technology

However, the existing 3G network and LTE network are high-bandwidth networks that can provide the same services as fixed networks, and in this scenario, there is no technology that directly authenticates mobile operator networks to access users.

Embodiment 1

[0075] image 3 is a schematic structural diagram of an access system provided by Embodiment 1 of the present invention, as shown in image 3 As shown, compared with the existing EPS architecture, the system adds a mobile intelligent access point, which is mainly composed of the following three parts: LTE UE module, WIFI AP module and core processing module; among them,

[0076] The LTE UE module is used for the mobile intelligent access point to access the LTE core network through the E-UTRAN network, providing high broadband resources for the mobile intelligent access point;

[0077] The WIFI AP module is a module for WIFI terminal access processing. Terminals with WIFI functions can access through mobile intelligent access points, and perform related HTTP services after passing network authentication;

[0078] The core processing module executes the mutual conversion processing between WIFI message / data and LTE message / data.

[0079] The mobile smart access point can also...

Embodiment 2

[0083] Figure 4 with Figure 5 They are schematic diagrams of a control plane protocol stack and a user plane protocol stack in Embodiment 2 of the present invention, respectively.

[0084] Such as Figure 4 The control plane protocol stack shown, where L2 / L1 (Layer 1 / Layer 2, Layer 1 / Layer 2) are the data link layer and the physical layer respectively, and the mobile intelligent access point and E-UTRAN, S-GW and P - The GW establishes the GTP-U user plane protocol stack, and then the mobile intelligent access point establishes an MIPv4 or PMIPv6 signaling tunnel with the P-GW of the user terminal to transmit messages convenient for signaling.

[0085] Such as Figure 5 As shown in the user plane protocol stack, the same mobile intelligent access point establishes a GTP-U user plane protocol stack with E-UTRAN, S-GW and P-GW, and the mobile intelligent access point and the user terminal P-GW Establish an MIPv4 or PMIPv6 user plane tunnel, thereby opening up the IP connec...

Embodiment 3

[0087] Image 6 It is a schematic flow diagram of a user equipment accessing a network through a mobile intelligent access point in Embodiment 3 of the present invention, as shown in Image 6 As shown, the process includes:

[0088] In steps 601-602, when the mobile intelligent access point is powered on, it initiates an attach process and registers in the core network. The non-access stratum message is encapsulated by the base station (E-UTRAN) in the initialization user message of the S1 interface and sent to the MME.

[0089] Step 603, if there is no context information of the user in the network, or the attach request message has no integrity protection, or the integrity protection fails, then the MME of the core network performs an authentication process for the user.

[0090] Steps 604-605, if there is no subscription data of the user in the MME, then send a location update request message to the Home Subscriber Server (3GPP AAA / HSS), which includes information such as m...

Abstract

The invention discloses an access method. The access method comprises the following steps: attaching a mobile intelligent access point to a core network, and acquiring the address of a 3GPP AAA (3rd generation partnership project authentication authorization accounting) server of a user terminal from the core network; performing EAP (extensible authentication protocol) authentication on the mobile intelligent access point and the 3GPP AAA server which is obtained by taking the mobile intelligent access point as the user terminal by the user terminal; initiating an access process to the mobile intelligent access point and acquiring the IP (Internet protocol) address of the user terminal by the user terminal; and selecting a P-GW (packet data network gateway) for the user terminal and establishing an underlying access tunnel by the mobile intelligent access point. The invention correspondingly discloses an access system and the mobile intelligent access point. Through the access method, the access system and the mobile intelligent access point, network authentication can be realized and the dependence on a fixed network is reduced, thus achieving more flexibility.

Description

technical field [0001] The present invention relates to the communication field, in particular to an access method, system and mobile intelligent access point. Background technique [0002] In the development process of packet data, the Packet Switched (PS) network includes GERAN (GSM EDGE radio access network, GSM EDGE radio access network) and UTRAN (Universal Terrestrial Radio Access Network, Universal Terrestrial Radio Access Network) part, The core network includes a Serving GPRS Support Node (SGSN) and a GPRS (General Packet Radio Service, General Packet Radio Service) gateway support node (Gateway GPRS Support Node, GGSN). The SGSN is the service support point for GERAN and UTRAN users to access the EPC network, and is responsible for user location update, paging management, and bearer management. Routing and forwarding, and protect the integrity of GPRS network data through firewall and filtering functions. GGSN also has a billing function. [0003] In order to ma...
