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.

Example Embodiment

[0074] Example 1
[0075] image 3 It is a schematic diagram of the structure of an access system provided by Embodiment 1 of the present invention, such as image 3 As shown, compared to the existing EPS architecture, the system adds a mobile smart 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 mobile smart access points to access the LTE core network through the E-UTRAN network, providing high broadband resources for mobile smart access points;
[0077] The WIFI AP module is a module for WIFI terminal access processing. Terminals carrying WIFI function can be accessed through a mobile smart access point, and perform related HTTP services after passing network authentication;
[0078] The core processing module performs mutual conversion processing between WIFI messages/data and LTE messages/data.
[0079] The mobile smart access point can also forward the user's HTTP request. The mobile intelligent access point can also obtain the default user 3GPP AAA address or the P-GW address of the user terminal from the network by registering with the network. When the user terminal P-GW and the P-GW of the mobile intelligent access point are the same P-GW , The mobile smart access point obtains the P-GW address as the P-GW address of the mobile smart access point.
[0080] The user terminal (UE) described in this embodiment may be a single-mode WIFI UE or a dual-mode WIFI+LTE UE. The present invention is collectively referred to as a user terminal for the convenience of description. For a dual-mode terminal, in any access mode When the signal is relatively weak, the existing implementation method can be used to continuously switch the service to the access mode with strong signal.
[0081] The LTE core network can provide authentication for mobile smart access points and user terminals accessing the mobile smart access point, and can also provide the same P-GW or different user terminals for the mobile smart access point or user terminals accessing the mobile smart access point. P-GW.

[0083] Figure 4 with Figure 5 They are respectively schematic diagrams of the control plane protocol stack and the user plane protocol stack of Embodiment 2 of the present invention.
[0084] Such as Figure 4 The control plane protocol stack shown, where L2/L1 (Layer 1/Layer 2, Layer 1/Layer 2) is the data link layer and the physical layer, respectively, and the mobile intelligent access point is connected to E-UTRAN, S-GW and P The GW establishes the user plane protocol stack of GTP-U, and then the mobile intelligent access point establishes the MIPv4 or PMIPv6 signaling tunnel in the P-GW of the user terminal for the transmission of messages with convenient signaling.
[0085] Such as Figure 5 As shown in the user plane protocol stack, the same mobile smart access point establishes a GTP-U user plane protocol stack with E-UTRAN, S-GW and P-GW, and the mobile smart access point and the user terminal P-GW Establish an MIPv4 or PMIPv6 user plane tunnel to open up the IP connection between the user terminal and the website server, and make the data channel between the user terminal and the website server normal. It is convenient for the user terminal and the website server to exchange IP packets.

Example Embodiment

[0086] Example 3
[0087] Image 6 It is a schematic diagram of the flow of the user equipment accessing the network through the mobile intelligent access point in Embodiment 3 of the present invention, such as Image 6 As shown, the process includes:
[0088] Steps 601-602, when the mobile smart access point is powered on, an attach process is initiated and registered in the core network. This non-access stratum message is encapsulated by the base station (E-UTRAN) in the initial user message of the S1 interface and brought to the MME.
[0089] Step 603: If there is no user context information in the network, or the attachment request message does not have integrity protection, or the integrity protection fails, the core network MME performs an authentication process for the user.
[0090] Steps 604 to 605, if there is no subscription data of the user in the MME, a location update request message is sent to the home user server (3GPP AAA/HSS), which includes information such as the mobility management unit identification, user identification, and update type. The home user server sends the user subscription data to the MME in the location update response message, which includes the subscription APN and the Qos parameters that each APN bears by default.
[0091] In step 606, in order to support the user to be always online, the MME uses the Qos parameter of the contracted default bearer to establish a default bearer on the core network side between the S-GW and the P-GW. The MME sends a session creation request to the P-GW through the S-GW, which carries the default bearer-related QoS parameters, charging features and other related parameters.
[0092] In step 607, the P-GW and PCRF/SPR establish an IP-can connection of the mobile intelligent access point.
[0093] Step 608, the P-GW authorizes the requested bearer QoS, and sends a session creation response to the MME through the S-GW.
[0094] In order to reduce the impact on the access network elements as much as possible, the P-GW can encapsulate the user's default 3GPP AAA address or the user terminal's P-GW address indication in the PCO and send it to the UE. PCO parameters are only transmitted between the mobile intelligent access point and the P-GW of the mobile intelligent access point, and other network elements are not resolved.
[0095] If the P-GW address of the user terminal is the address of the current P-GW, the P-GW of the user terminal is the same as the P-GW of the mobile intelligent access point.
[0096] Step 609: After the core network side default bearer is established, the corresponding radio bearer must be activated. The MME sends the UE context, that is, the UE context of the mobile smart access point, and the established bearer Qos parameters to the base station through the initial context establishment request message. , The attachment acceptance message is also encapsulated in the message and sent to the user. The attach accept message carries the temporary user identity allocated to the UE by the MME and a request to establish a bearer context for the UE.
[0097] In steps 610-611, the base station establishes a corresponding air interface bearer according to the bearer information indicated by the core network.
[0098] Step 612: After the establishment of the air interface bearer is completed, the base station replies with an initial context establishment response message to notify the core network.
[0099] Step 613: The mobile intelligent access point returns a registration completion message to the MME through the base station.
[0100] Step 614: The user terminal executes a layer 2 initial access procedure specific to the non-3GPP access network to the mobile intelligent access point.
[0101] Step 615: The user terminal performs EAP authentication with the mobile smart access point and the default 3GPP AAA server selected by the mobile smart access point for the user terminal.
[0102] Step 616: After successful authentication and authorization, the user terminal executes a non-3GPP access-specific layer 3 attachment process to the mobile smart access point and is triggered, and the mobile smart access point selects the P-GW for UE access;
[0103] Step 617: The user terminal initiates a DHCP discovery process to the mobile intelligent access point.
[0104] Step 618: The mobile intelligent access point sends a proxy binding update message to the P-GW of the selected user terminal;
[0105] Step 619: The P-GW of the user terminal and the PCRF/SPR establish an IP-can connection of the user terminal.
[0106] When the P-GW of the user terminal is co-located with the P-GW of the mobile intelligent access point, the P-GW of the user terminal obtains the user's quality of service parameters, and will move to the mobile intelligent access point according to the service quality parameters of the mobile intelligent access point. The policy server of the smart access point updates the service quality of the mobile smart access point to ensure that the user's service quality is guaranteed.
[0107] When the P-GW of the user terminal is separated from the P-GW of the mobile smart access point, the P-GW address of the mobile smart access point can be obtained in the binding update request, and the user's P-GW obtains the relevant service parameters Then, the user’s quality of service and the corresponding mobile smart access point are delivered to the P-GW of the mobile smart access point, and the P-GW of the mobile smart access point sends the mobile smart access to the mobile smart access point according to the service quality of the mobile smart access point. The policy server of the point updates the service quality parameters of the mobile smart access point to ensure that the user's service quality is guaranteed; or the policy server of the user terminal carries the service quality parameters of the user equipment to notify the mobile smart access according to the mobile smart access point information The policy server of the mobile smart access point updates the service quality parameters of the P-GW of the mobile smart access point according to the service quality parameters of the user equipment and the service quality parameters of the mobile smart access point to ensure the user terminal The quality of service.
[0108] Step 620: The P-GW of the user terminal interacts with 3GPP AAA/HSS, and will save its own address information;
[0109] Step 621: The P-GW of the user terminal returns a proxy binding confirmation message to the mobile intelligent access point, and the message carries the IP address allocated by the P-GW for the user terminal.
[0110] So far, the mobile intelligent access point has established the PMIPv6 tunnel with the P-GW of the user terminal, and the MIPv4 tunnel can also be established by using the existing technology.
[0111] Step 622: The mobile intelligent access point returns a DHCP indication message to the user terminal. The message carries a DHCP server address, and the DHCP server address is the mobile intelligent access point address.
[0112] Step 623: The user terminal initiates a DHCP request to the mobile smart access point.
[0113] In step 624, the mobile smart access point sends a DHCP response message back to the user terminal, the message carrying the IP address allocated by the mobile smart access point to the user terminal in step 621.
[0114] Step 625: The trusted non-3GPP IP access gateway returns a layer 3 attachment complete message to the UE.
[0115] So far, the user terminal has been certified by the 3GPP network and can use the LTE network as a backhaul network to perform normal data services.
