Method, device and system for identifying user identity based on ipv6 address

Abstract

The invention discloses a method, device and system of identifying a user identity based on an IPv6 (Internet Protocol version 6) address; wherein when a PCRF (Policy and Charging Rules Function) unit receives a search request which is sent by a service platform and is used for searching appointed user identity information, the IPv6 address associated with an appointed user is searched; when the IPv6 address is legal, the serial number value of a secret key base is determined according to the prefix part in the IPv6 address; a two-dimensional secret key associated with the serial number value is obtained from the secret key base; a working secret key is generated by utilizing the two-dimensional secret key and the prefix part in the IPv6 address; the IMSI (International Mobile Subscriber Identification Number) ciphertext in the IPv6 address is decrypted by utilizing the working secret key, thus obtaining IMSI information; the user identity information associated with the IMSI information is searched; the IMSI information and the associated user identity information are sent to the service platform as search results. Through hiding the IMSI information of the user in the distributed IPv6 address, it is unnecessary to maintain the online information system of dynamic users; the IMSI information can be obtained only by decrypting; and the tracing accuracy and efficiency of the user identity can be effectively improved.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a method, device and system for identifying user identities based on IPv6 addresses. Background technique [0002] In the era of 3G services, due to the limitation of IPv4 (Internet Protocol version 4, Internet Protocol version 4) address coding space limitations, the allocation of IP addresses is mainly based on services to divide the corresponding address segments, which has a large granularity and cannot be based on The user assigns an IP address. [0003] In order to solve the problem of user identification, many products on the current network, such as 3G idle-time traffic packet services, rely on user online information databases to identify users. The network platform side needs to dynamically maintain a user online information database to associate the user's IP address with the IMSI (International Mobile Subscriber Identification Number) number, and the online information...

Problems solved by technology

[0015] In the above solution, the PCRF network element needs to obtain the user's online and offline information in real time through the Gx interface, and update the online database record based on the online and offline information; Accurate, even the IP address mapping disorder, and even lead to the issue of follow-up subscription fees, leading to user complaints
