Due to the advantages of short distance and direct connection, the D2D technology can improve the use efficiency of wireless resources and expand the network coverage, so a great deal of research is obtained in the construction of 5G, the D2D technology can be applied to more scenes in the future, and the user experience is improved.
The 5G D2D communication technology is essentially an end-to-end communication technology of a terminal, and in the 5G D2D technology, the terminal scans each frequency band to discover a nearby D2D terminal, even if the D2D terminals find each other to complete direct communication, security of the communication terminal needs to be considered, and if the terminal is a malicious terminal, a large security risk exists.
In summary, there is a need for a solution to the above-mentioned problems, in which the password is set to hide the target D2D terminal, the target D2D terminal encrypts the discovery signal of D2D using the password, and the slave D2D terminal that does not decrypt using the password cannot detect the discovery signal of the target D2D terminal, thereby overcoming the above-mentioned problems.

Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1-3, the method for implementing a terminal hiding function based on the 5G D2D technology provided by the invention comprises the following steps:
s10, setting a target D2D terminal as a hidden terminal, and setting a password key;
s20, the target D2D terminal encrypts and transmits the discovery signal by using a password key;
s30, the slave D2D terminal inputs a password, if the password is correct, the discovery signal of the target terminal is detected and analyzed, the discovery signal is responded, and if the password is incorrect, the operation is finished;
and S40, the target D2D terminal receives the response information of the slave D2D terminal and starts mutual direct connection communication.
Specifically, as shown in fig. 2, 5G UE1 is a hidden D2D terminal, a hidden password is set by a user, UE1 encrypts a discovery signal of D2D by using the hidden password, UE2 and UE3 perform blind detection on nearby discovery signals, the discovery signal resolved to UE1 cannot be detected without a password or by inputting an incorrect password, and the discovery signal resolved to UE1 can be detected only by inputting a correct password, so that the UE2 can correctly resolve the discovery signal of UE1 due to inputting a correct password, and thus UE2 finds UE 1; on the other hand, since the UE3 cannot analyze the discovery signal from the UE1 because of no password or an incorrect password input, the presence of the UE1 cannot be known, and the purpose of hiding the UE1 is achieved.
In some embodiments, before step S10, the method further includes that the 5G gbb performs common configuration on D2D discovery, and informs all other terminals supporting D2D discovery function in the cell of relevant configuration information through system broadcast information.
Specifically, in the discovery process of the 5G D2D terminal, the gNB needs to reserve a part of resources for D2D discovery and is dedicated to transmitting and detecting the D2D discovery signal, and needs to perform common configuration on D2D discovery through the base station, and notify all other terminals supporting the D2D discovery function in the cell of relevant configuration information through a system broadcast message. The discovered D2D terminal randomly or purposefully selects time frequency resources according to the cell public configuration information to transmit discovery signals; the discovery end device performs blind detection in the D2D discovery signal resource pool according to the cell configuration information, and completes the discovery process of D2D in this process.
In some embodiments, the setting of the target D2D terminal as the hidden terminal in the step S10 is to open the hidden function of the target D2D terminal through the UI interface entry setting.
Specifically, a user can set a hidden function of an open target D2D terminal through a UI interface entry, and set a hidden password, after the function setting is successful, the hidden D2D terminal encrypts and transmits a Discovery signal of the D2D terminal by using the password, that is, the D2D Discovery Sequence Message is encrypted by using the hidden password, and a terminal which does not know the password cannot analyze the Message, that is, cannot recognize the Discovery signal. For a user who knows the hidden password to input the hidden password, the Discovery signal of the hidden D2D terminal is parsed, for example, UE2, and after the parsing is successful, a Response message D2D Discovery Response needs to be replied to the hidden D2D terminal. From there, hidden D2D terminals are discovered by UE 2. D2D secure communication for encrypting and decrypting data using the hidden password is subsequently continued. When the hidden password of the hidden D2D terminal is changed, the terminal communicating with the old password cannot sense the hidden D2D terminal any more, and needs to input a new password before being identified again.
In summary, the working principle of the invention is as follows:
the invention provides a method for realizing a terminal hiding function based on a 5G D2D technology, which comprises the following steps: s10, setting a target D2D terminal as a hidden terminal, and setting a password key; s20, the target D2D terminal encrypts and transmits the discovery signal by using a password key; s30, the slave D2D terminal inputs a password, if the password is correct, the discovery signal of the target terminal is detected and analyzed, the discovery signal is responded, and if the password is incorrect, the operation is finished; and S40, the target D2D terminal receives the response information of the slave D2D terminal and starts mutual direct connection communication. The target D2D terminal is hidden by setting a password, the target D2D terminal encrypts the discovery signal of the D2D by using the password, and the slave D2D terminal which does not use the password for decryption cannot detect the discovery signal of the target D2D terminal, so that the access and the request of a strange D2D terminal are prevented, and the security risk and the interference are reduced.
It should be understood that equivalents and modifications of the technical solution and inventive concept thereof may occur to those skilled in the art, and all such modifications and alterations should fall within the scope of the appended claims.
