Description

Registration information processing method, data processing device and system The present application claims to be submitted to the Chinese Patent Office on December 4, 2007, the application number is 200710193857.X, and the invention name is "registration information processing method, data processing device and system" Chinese patent Priority of the application, the entire contents of which are incorporated herein by reference. Technical field

The present invention relates to communication technologies, and more particularly to a registration information processing method, a data processing apparatus and system. Background technique

After users access the network, when they move between different areas, they often encounter the situation of switching operators and network access methods. Because different operators and different access methods have different network coverage and applicable conditions, users When switching operators and access modes, you need to release the existing data link and re-establish a new data link.

Each mobile IP user has its own home network. When the mobile node (MN) is in the home network, it can communicate with the external network directly through the home agent (HA), all sent to the mobile node (MN). The data packets of the mobile node are sent to the HA and forwarded by the HA to the mobile node. The data packets sent by the mobile node are first sent to the HA through the data flow link, and are forwarded by the HA to the destination node.

When the mobile node leaves the home network and accesses a foreign network, the mobile node first establishes a connection with a foreign agent (FA) of the foreign network, reports its HA address and its home address to the FA, and from the field. The network obtains an available Care-of-Address (COA), and the FA establishes a user-related information table based on the mobile node's HA address, home address, COA, and the data link between the FA and the mobile node. After obtaining the COA, the mobile node sends a mobile IP registration request message to the HA, requesting to register its current COA on the HA, and the HA creates a registration record for the user according to the registration request, and the registration record includes network access for identifying the mobile node user. Logo ( Network Access Identifier (NAI), the home address and care-of address assigned by the HA to indicate the IP address of the mobile node user in the home network, can be recorded as <NAI, home address, COA>. Thereafter, the mobile node periodically sends registration update request information to the HA to update its registration record on the HA. At this time, the mobile node user information stored on the HA includes a registration record of the mobile node user and data forwarding mode information for forwarding data to the mobile node, for example, a tunnel mode. After the mobile node registers with the HA on the HA, a data forwarding table is created for the mobile node on the FA and the HA respectively.

After HA creates a registration record for the user, all the downlink data sent to the mobile node, whose destination address is the home address of the mobile node, is first sent to the HA of the mobile node, and the HA queries the first data transfer stored on the HA according to the home address. After the tunnel is encapsulated according to the forwarding mode information recorded therein, the data is forwarded to the FA according to the COA address in the registration record. After receiving the downlink data, the FA uses the <11 address, COA address, and home address> as the index. Querying the second data forwarding table stored on the FA, querying the data link where the mobile node is located, and transmitting the data link to the mobile node by using the data link. The uplink data sent by the mobile node is first sent to the FA through the data link where it is located, and is encapsulated by the FA and sent to the HA according to the HA address registered by the mobile node, and then decapsulated by the HA and then forwarded to the destination node. Alternatively, the FA may also be based on the FA. The home address registered by the mobile node directly performs route forwarding. At this time, the path through which the uplink and downlink data packets pass is different, which is called a three-sided route.

The number of users in the CDMA2000 network is large. If the NAI used by each user is different, the NAI at this time can be called a single-user NAI, which requires wasting more NAI network resources. Moreover, the amount of information maintained by the operator is required. Large, high cost; In addition, the storage, information processing and maintenance performance of HA is also very high. Therefore, the CDMA2000 packet domain protocol proposes that multiple users use the same NAI. At this time, the NAI is also called multi-user shared NAI, and the HA is required to support the mobile node to access the network through multi-user shared NAI. If the HA can accept the same NAI but different homes. This function can be implemented by registering request information for address" and creating different registration records.

In carrying out the process of the present invention, the inventors have found that the prior art has at least the following problems:

The existing mobile IP technology solution cannot achieve multi-user shared NAI, and the NAI can only be unique. Identify a mobile IP user. Since the security association parameters between MN-FA, MN-HA, and MN-AAA are all indexed by NAI, if multiple users are simply used the same

MN-AAA security association parameters, HA cannot identify different users according to NAI, which causes HA to process messages of different users as messages of the same user, so that users cannot use mobile IP services normally; and, due to HA Mis-delivery or malicious destruction of some users may cause data that should be sent to the mobile node of the A user to be sent to the node of user B, thereby causing leakage of user A information, and this serious security problem exists.

The same problem exists when multiple users share NAI and are located in different foreign networks. Summary of the invention

All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

In the embodiment of the present invention, when the FA forwards the registration request information or the registration update request information sent by the mobile node to the HA, the mobile node user identifier is written into the registration request information or the registration update request information, so that the HA can uniquely identify the user identifier and the NAI. The user, in the case of realizing multi-user shared NAI, effectively ensures the security of the user's normal use of the IP service and the user information. Detailed description.

As shown in FIG. 1 , it is a flowchart of a first embodiment of a registration information processing method of the present invention, which includes the following steps:

Step 101: The FA generates and sends registration information to the HA of the MN according to the registration request or the registration update request sent by the MN, where the registration information includes the user identifier and the NAI. The user identifier and the NAI uniquely identify a mobile node user, for example, an International Mobile Subscriber Identity (IMSI), and the registration information may be registration request information or registration update request information.

Step 102: The HA updates the user information and/or the first data forwarding information corresponding to the user identifier and the NAI in the registration information according to the registration information, that is, updates the user information corresponding to the user identifier and the NAI, and/or the first data forwarding. Any or both of the information.

When the registration information is processed, the registration information is first identified as the registration request information or the registration update request information. Specifically, the user information table stored in the pre-stored information may be the same as the user identifier and the NAI carried in the registration information. The user information identifies the registration information and performs corresponding processing. Write the mobile node user ID to the registration request information or the registration update information,

The HA uniquely identifies a registration request information or registration update information by using the NAI and the user identifier, so that the HA can uniquely identify the mobile IP user according to the user identifier and the NAI, and uniquely identify the registration request information or the registration update information according to the NAI and the user identifier, thereby avoiding The user information is confused by the multi-user shared NAI, which effectively ensures the security of the user's normal use of the IP service and the user information.

When the MN leaves the home network and accesses a foreign network, the FA sends a link request to the FA of the foreign network, and sends its user identification IMSI, NAI, HA address and its home address to the FA, and establishes a link connection with the FA. And get one available from the foreign network

COA: COA1, FA according to the mobile node's IMSI, NAI, HA address, home address,

The COA, and the data link between F A and the MN establish a user related information table, namely: a second user information table, and a second data forwarding table. After that, the MN can pass the FA to it.

The HA sends registration request information or registration update request information. As shown in Table 10 below, the user information about the MN on the second user information table established for the FA:

Table 1 Second User Information Table on FA

The second user information table on the FA may also store other information of the MN user according to actual needs, for example: tunnel parameters.

As shown in FIG. 2, it is a flowchart of a second embodiment of a registration information processing method of the present invention, which includes the following steps:

Step 201: The FA receives a registration request or a registration update request sent by the MN, and generates and sends registration information to the HA of the MN according to the registration request or the registration update request, where the registration information includes the NAI, and may further include the MN. User ID: IMSI Cell Extension.

The IMSI cell extension format may use the Normal Vendor/Organization Specific Extension (NVSE) format defined in RFC3115. In this case, if the HA can identify the IMSI information in the NVSE format, if it is not recognized or The NVSE format message is not supported, and the IMSI information in the NVSE format can be skipped to continue processing other pieces of information in the registration information. As shown in Table 11 below, the NVSE format requirements defined for the RFC3115 protocol are:

Table 2 NVSE format requirements

0 1 2
