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 D2D terminal mode communication selection method in 5G hybrid networking according to the present invention includes:
s1, establishing a trusted communication list according to an OTT application account, a target terminal identification, a trusted type and a security level;
s2, D2D is carried out by the D2D terminal to search peripheral target terminals;
s3, the D2D terminal initiates a communication service request to a target terminal;
s4, the D2D terminal identifies whether the target terminal is found by the D2D terminal or not according to the ID of the target terminal, if so, the step is switched to S5, and if not, the traditional cellular communication mode is selected for communication;
s5, retrieving a corresponding record from the trusted communication list by the D2D terminal equipment according to the ID of the target terminal;
S6, if the corresponding record is searched in the credible communication list, switching to S7, and if the corresponding record is not searched, switching to a mode that the user selects the corresponding communication mode through a UI;
s7, obtaining a corresponding security level in the trusted communication list, if the security level is greater than a first preset value, turning to S9, if the security level is lower than the first preset value and is greater than a second preset value, turning to S8, if the security level is lower than the second preset value and is greater than a third preset value, turning to a mode that a user selects a corresponding communication mode through a UI, and if the security level is lower than the third preset value, selecting a traditional cellular communication mode;
s8, matching the OTT application account with the account of the target terminal, if the OTT application account and the account of the target terminal are consistent, switching to S9, and if the OTT application account and the account of the target terminal are inconsistent, switching to a mode that a user selects a corresponding communication mode through a UI;
s9, switching to a direct mode between D2D terminals, and updating the trusted communication list.
Specifically, the trusted communication list mainly includes an OTT application account, a target terminal ID, a trusted type, a security level, and the like. The OTT application account refers to a user account of the OTT application of the target terminal, such as a Whatsapp account and a WeChat account; the target terminal ID refers to a unique physical identifier that can identify the target terminal, such as an MAC address, an IMEI number, and the like; the trusted type: the target terminal and the D2D terminal can realize the secure communication between the two parties through what secure connection, which may be WiFi Direct authentication, BT pairing authentication, or binding of OTT application account. For example: a. if the target terminal establishes WiFi Direct communication with the D2D terminal once, the trusted type is WiFi Direct authentication; b. if the target terminal establishes BT pairing with the D2D terminal, the trusted type is BT pairing authentication; c. if the target terminal and the D2D terminal have communicated through the Whatapp application, the trusted type is WhatAPP binding; d. if the target terminal and the D2D terminal have not established any trusted authentication or binding once, the trusted type is unknown and will not be recorded in the trusted list; e. if the target terminal is blacklisted by the end user of D2D, the trusted type is NULL. The security level refers to the security level corresponding to the credible type, and the larger the numerical value is, the higher the security level is, the safer and more credible is. The value-1 corresponds to a trusted type NULL, namely a blacklist member; the value 0 corresponds to the trusted type unknow; the number 1 corresponds to OTT application binding; number 2 corresponds to P2P communication pair authentication. When a user performs Bluetooth pairing, the corresponding record is automatically added, when the user performs WiFi linking, the corresponding record is automatically added, when the user performs WeChat chatting, the corresponding record is automatically added, but when the user adds a terminal into a blacklist, the corresponding record is automatically added, so that the table is a process of dynamic establishment and automatic learning. When a terminal is in a network environment of hybrid networking of D2D and a cellular network, dynamically performing a discovery process of D2D to discover surrounding devices, when a D2D terminal initiates a communication service request, firstly detecting whether a target terminal is discovered by the terminal D2D according to an ID (identity) of the target terminal, if the target terminal is discovered to be around the D2D terminal, the D2D terminal device retrieves a corresponding record from the trusted D2D terminal list according to the ID of the target terminal, and if the record meeting the condition is detected, acquiring a corresponding security level, and if the security level is greater than or equal to 2, initiating a pass-through mode between the D2D terminals; if the security level is less than 2 and greater than or equal to 1, matching whether the OTT account of the current target terminal is consistent with the OTT account in the record, and if so, initiating a direct mode between the D2D terminals; otherwise, the user can prompt and confirm the communication mode, so that the communication safety of the D2D is improved, and the user experience is improved.
In some embodiments, said having the user select the corresponding communication mode via the UI comprises selecting the D2D pass-through mode or selecting the conventional cellular communication mode.
In some embodiments, both the target terminal and the D2D terminal may act as an active caller and a called caller, i.e., the call flow and the called flow are reversible.
In some embodiments, the first, second and third preset values may be ranges or specific values, and the preset values are determined according to actual conditions or experience.
In summary, the working principle of the invention is as follows:
