Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for obtaining an IPv6 address prefix of a mobile terminal.
Background
Currently, various mobile network signaling analysis systems which have been widely applied extract international mobile subscriber identification codes (IMSI, international Mobile Subscriber Identity), mobile subscriber ISDN numbers (MSISDN, mobile Subscriber ISDN number), base station identifications (Cell IDs) and IP addresses of mobile terminals from signaling and user plane data of network elements accessing a mobile network, obtain internet surfing data of a user from the user plane data, and correlate the signaling and user plane data of the same user, thereby identifying identity information and location information of various application data.
IPv6 (Internet Protocol Version, internet protocol version 6) is an upgraded version of IPv4 (Internet Protocol Version, internet protocol version 4). The most significant change in IPv6 versus IPv4 is the increase in the length of the IP address from 32 bits to 128 bits. The 128-bit IPv6 address is divided into an address prefix and an interface address. In the case where a prefix proxy is not employed, the mobile terminal address prefix is typically the first 64 bits and the interface address is the last 64 bits. Wherein the address prefix is assigned to the mobile terminal by the network device; the interface address may be generated by the terminal itself or may be issued by the network.
The mobile network, part of the signaling interface will issue the mobile terminal real IPv6 prefix, e.g. the N4 interface in 5G, and the S11 and Sx interfaces in 4G. However, part of the signaling interfaces do not issue the IPv6 prefix of the mobile terminal, for example, the IPv6 interface address is issued in the N2 and N11 signaling interfaces of 5G, and the IPv6 interface address is issued in the network side of the S1-MME signaling interface of 4G. In general, the signaling analysis system adopts multi-interface association, and can acquire the real IPv6 prefix of the mobile terminal through interfaces such as N4 or S11.
Under the condition of limited signaling access, such as the condition that only a 5G signaling surface N2 interface and a user surface N3 interface are accessed, a 4G signaling surface S1-MME interface and a user surface S1-U interface are accessed, the real IPv6 prefix of the mobile terminal cannot be obtained through other signaling interfaces. Therefore, when only the signaling interface which only issues the address of the IPv6 interface is accessed, but the signaling interface which issues the IPv6 prefix is not accessed, and the signaling interface which issues the IPv6 prefix is not accessed, there is a problem of how to acquire the real IPv6 prefix of the mobile terminal.

The following describes a method and apparatus for acquiring an IPv6 address prefix of a mobile terminal according to the present invention with reference to fig. 1 to fig. 4.
Fig. 1 is a flow chart of a method for obtaining an IPv6 address prefix of a mobile terminal according to the present invention. As shown in fig. 1, an execution body of a method for obtaining an IPv6 address prefix of a mobile terminal according to an embodiment of the present invention may be a device for obtaining an IPv6 address prefix of a mobile terminal, where the method includes: step 101 and step 102.
In order to facilitate description of the method for acquiring the IPv6 address prefix of the mobile terminal provided by the embodiment of the present invention, an implementation process of the method for acquiring the IPv6 address prefix of the mobile terminal provided by the embodiment of the present invention is described below by taking an access 5g N2 signaling interface and an N3 data interface as examples, and it can be understood that the 5g N2 signaling interface is an interface that only issues an address of the IPv6 interface.
Step 101, matching with a tunnel information session lookup table based on target tunnel information in a data packet in a mobile user plane interface; the tunnel information session inquiry table is used for storing the corresponding relation between the tunnel information of the mobile terminal surfing the internet and the session.
Specifically, tunnel information in a data packet in the mobile user plane interface may be obtained as target tunnel information.
Tunnel information, which may include the IP address and TEID (tunnel endpoint identification Tunnel Endpoint Identifier) of the tunnel, and the like.
The tunnel information session lookup table is a pre-established table, and each record in the table is used for describing a correspondence between tunnel information and a session. The tunnel information corresponds to the session, which indicates that the tunnel information is the tunnel information of a certain mobile terminal for surfing the internet, the session is the session of the mobile terminal, and the mobile terminal is the mobile terminal corresponding to the tunnel information.
The session may be indicated by session information. Session and session information one-to-one. Alternatively, the session information may be a pointer to the session.
Illustratively, table 1 shows a tunnel information session lookup table.
Table 1 tunnel information session lookup table
| IP address of tunnel | TEID of tunnel | Session pointer |
| 10.0.0.1 | 0x00000001 | 0x12345600 |
| 10.0.0.3 | 0x00000002 | 0x12345700 |
| 10.0.0.2 | 0x00000006 | 0x12345800 |
| 10.0.0.4 | 0x00000003 | 0x12345900 |
As can be seen from table 1, when the IP address of a tunnel in the user plane data is 10.0.0.3 and the TEID of the tunnel is 0x00000002, the pointer of the corresponding session is 0x12345700, and the session of the mobile terminal corresponding to the tunnel information can be accessed by using the pointer, thereby obtaining the identity information, the location information, and the like of the mobile terminal.
The protocol layers typical of N3 user plane data are shown in table 2.
Table 2 N3 user plane data protocol layer table
| MAC layer |
| Tunnel outer layer IP layer |
| UDP layer |
| GTP layer |
| Tunnel inner layer IP layer |
| Inner layer transmission layer of tunnel |
| Tunnel inner layer data |
As shown in table 2, the address of the tunnel outer IP layer is the tunneling address of the network device, and corresponds to the tunneling layer address. In addition, the GTP layer includes a tunnel TEID, so that the IP address of the tunnel and the TEID of the tunnel can be extracted from the N3 user plane packet.
After extracting the target tunnel information such as the IP address of the tunnel and the TEID of the tunnel, the target tunnel information may be used as a key to match the tunnel information session lookup table, and whether a record of session information matched with the target tunnel information exists in the tunnel information session lookup table is queried.
When the tunnel information in any record in the tunnel information session lookup table is the same as the target tunnel information, it is described that there is a record of session information matching the target tunnel information, and the session information in the record is the session information matching the target tunnel information.
In the case where the tunnel information in each record in the tunnel information session lookup table is different from the target tunnel information, it is indicated that there is no record of session information matching the target tunnel information.
Specifically, if session information matching the target tunnel information exists in the tunnel information session lookup table, it may be determined whether the packet is an ICMPv6 packet.
If yes, the ICMPv6 data packet can be analyzed, and the type of the ICMPv6 data packet can be further judged.
If the ICMPv6 packet is of the type of the route advertisement message (Router Advertisement), i.e. the packet carries an ICMPv6 route advertisement message, it may be further determined whether the ICMPv6 route advertisement message carries an IPv6 prefix information (prefix information) extension field.
If so, the IPv6 prefix and IPv6 prefix length can be extracted from the field. The IPv6 prefix is the real prefix of the IPv6 address of the mobile terminal corresponding to the target tunnel information.
According to the embodiment of the invention, the ICMPv6 router notification message in the user plane data packet is related to the target tunnel information, the ICMPv6 router notification message is analyzed, the IPV6 address prefix of the mobile terminal is obtained, the real IPv6 address prefix of the mobile terminal can be obtained under the condition that only the signaling interface which only issues the IPv6 interface address is accessed and the signaling interface which issues the IPv6 prefix is not accessed, and the problem that the real IPv6 address prefix of the mobile terminal is obtained under the condition that only the signaling interface which only issues the IPv6 interface address is accessed and the signaling interface which issues the IPv6 prefix is not accessed can be solved.

When the base station sends a data packet to the core network, the N3 interface data packet carries the IP address and the TEID of the tunnel at the core network side; when the base station receives the data packet from the core network, the N3 interface data packet carries the IP address and TEID of the tunnel at the base station side.
