Embodiment 1

[0041] As the basic embodiment of the present invention, with reference to the description attached figure 1 , the present invention includes a DNS redirection method based on relay access, respectively establishing information communication connections between the public network UE and the private network eNB, the private network eNB and the private network UE, and the private network UE and the public network eNB, so that The initial attachment connection between the public network UE and the private network UE is established, the private network UE completes the authentication relay access and performs DNS redirection for the modification of the transmission data.

[0042] Among them, DNS redirection for modification of transmitted data specifically includes:

[0043] a. The public network UE transmits the IP message to the private network eNB. After receiving the message, the private network eNB locates the DNS data packet, bypasses encryption and modifies the message data...

Embodiment 2

[0048] As a preferred embodiment of the present invention, the present invention includes a DNS redirection method based on relay access, which connects public network UE and private network eNB, private network eNB and private network UE, and private network UE and public network eNB The information communication connection is established between the public network UE and the private network UE respectively, so that the establishment of the initial attachment connection between the public network UE and the private network UE is completed, the private network UE completes the authentication relay access, and performs DNS redirection for the modification of the transmission data.

[0049] The establishment of the initial attachment connection of the public network UE specifically includes:

[0050] ① After the public network UE is turned on, it will first select the PLMN (Public Land Mobile Network), and then perform physical downlink channel synchronization to start searching ...

Embodiment 3

[0061] As the best implementation mode of the present invention, with reference to the attached figure 2 , the present invention includes a DNS redirection method based on relay access, respectively establishing information communication connections between the public network UE and the private network eNB, the private network eNB and the private network UE, and the private network UE and the public network eNB, so that The initial attachment connection between the public network UE and the private network UE is established, the private network UE completes the authentication relay access and performs DNS redirection for the modification of the transmission data.

[0062] Wherein, the establishment of the initial attachment connection of the public network UE specifically includes:

[0063] ① After the public network UE is turned on, it will first select the PLMN (Public Land Mobile Network), and then perform physical downlink channel synchronization to start searching for ce...

Abstract

The invention relates to the technical field of communication, in particular to a DNS (Domain Name System) redirection method based on relay access, which comprises the following steps that: initial attachment connection between public network UE (User Equipment) and private network UE is established, the private network UE completes authentication relay access, and DNS redirection is carried outon transmission data modification. According to the invention, the problems of complex DNS redirection operation, easy investigation and discovery and low success rate in the prior art can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a DNS redirection method based on relay access. Background technique [0002] The public security network has special requirements for the collection of user identity information. Based on the LTE electronic fence, it is of great value to use mobile terminal information to analyze and track users. The existing technology allows the terminal device to perform the TAU (Tracking Area Update) process by setting an abnormal TAC (Tracking Area Code), modify it in the complete TAU process, and send the NAS message of Identity ReqUEst after completing the RRC connection, and set The values ​​of Security header type and Identity reqUEst message identity in IdentityReqUEst make the terminal report its own IMSI code, and then reject the TAU process, thereby avoiding two-way authentication and allowing the terminal to connect back to the original serving cell. As the unique identity o...
