Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and more specific, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1-3, the method for selecting D2D terminal mode communication under 5G hybrid networking provided by the present invention includes the following steps:
s1, dynamically establishing a relation table of D2D terminal mode selection according to a time period, the geographic position of the D2D terminal and a target terminal identifier;
s2, D2D terminal performs D2D searching for peripheral target terminals;
s3, the D2D terminal initiates a communication service request to the target terminal;
s4, the D2D terminal identifies whether the target terminal is found by the D2D terminal according to the ID identification of the target terminal, if so, the S5 is shifted to, and if not, the traditional cellular communication mode is selected for communication;
s5, the D2D terminal equipment retrieves the corresponding record from the relation table according to the ID of the target terminal;
s6, if the record in the data effect is searched in the relation table, switching to S7, and if the record in the data effect is not searched in the relation table, switching to a communication mode which is selected by the user through the UI;
s7, acquiring the current time period and corresponding geographic position information;
s8, detecting whether the acquired time period and geographic position information are consistent with those in the relation table, if so, switching to a direct mode between the D2D terminals, and if not, switching to a communication mode which is automatically selected by a user through a UI.
Specifically, the relationship table of D2D terminal mode selection includes information such as a time period, a geographic location, and a target terminal identifier. The establishment of the relationship table can be created manually by a user or can be obtained by dynamic learning. The user manually creates a time period input through the UI interface, a geographic position (which is not a longitude and latitude index and can be converted into longitude and latitude according to a specific map position) and a target terminal ID (which can be manually input a specific number and can also select corresponding target terminal information from a D2D device discovery interface); the data input by the user can be directly used as effective data. Thus, the table contains fields of type, frequency, whether the data is valid: the type is whether the data is user-entered or dynamically learned; the frequency refers to the frequency of D2D communication of the user in the same geographic position and the same target terminal in the same current time period; the data validation refers to whether the currently recorded data can be used as a basis for mode selection of the D2D terminal. When a terminal is in a network environment of a D2D and cellular network mixed networking, a D2D discovery process is dynamically carried out, surrounding devices are discovered, when the D2D terminal initiates a communication service request, whether the target terminal is discovered by the terminal D2D or not is firstly detected according to the ID identification of the target terminal, if the target device is found around the D2D terminal, the D2D terminal device retrieves corresponding data effective records from the relation table according to the ID of the target terminal, if the records meeting the conditions are detected, the D2D terminal device starts to detect whether the current time period and the geographic position are matched with the records in the relation table, if the records are matched, a direct mode between the D2D terminals is initiated, and the records are updated into the relation table; otherwise, the user prompt can be used for confirming which mode is used for communication.
In some embodiments, in step S6 or S8, if the user selects the D2D through mode through the UI, the data in the relationship table is updated, so that the relationship table adds a new target terminal, and when the call is encountered again next time, the communication mode can be selected more intelligently, thereby implementing dynamic learning of the relationship table.
In some embodiments, the data is validated according to whether the D2D communication frequency of the same geographic location and the same target terminal exceeds a specific threshold value in the same time period, and whether the data is validated is determined according to the communication frequency, and when the D2D communication frequency of the same geographic location and the same target terminal exceeds the specific threshold value (for example, the threshold value is 4, which may take an empirical value) in the same time period, the data is considered to be validated.
In some embodiments, both the target terminal and the D2D terminal may act as active calling and called terminals. The called flow is also applicable to the called flow of the D2D terminal, when the D2D terminal detects that a service request is received, whether the ID of the terminal initiating the service is in a relation table or not can be detected, if the ID exists and the terminal is found by the D2D terminal, whether the current time period and the position are matched with effective records in the relation table or not is started to be detected, and if the ID is matched with the effective records in the relation table, a direct mode between the D2D terminals is performed, and response is performed; otherwise, the user prompt can be used for confirming which mode is used for communication.
In some embodiments, the geographic location may be matched within a range of longitude and latitude thresholds, and a certain deviation threshold may be set without a complete numerical match.
In summary, the working principle of the invention is as follows:
the invention provides a D2D terminal mode communication selection method under 5G mixed networking, which is characterized by comprising the following steps: s1, dynamically establishing a relation table of D2D terminal mode selection according to a time period, the geographic position of the D2D terminal and a target terminal identifier; s2, D2D terminal performs D2D searching for peripheral target terminals; s3, the D2D terminal initiates a communication service request to the target terminal; s4, the D2D terminal identifies whether the target terminal is found by the D2D terminal according to the ID identification of the target terminal, if so, the S5 is shifted to, and if not, the traditional cellular communication mode is selected for communication; s5, the D2D terminal equipment retrieves the corresponding record from the relation table according to the ID of the target terminal; s6, if the record in the data effect is searched in the relation table, switching to S7, and if the record in the data effect is not searched in the relation table, switching to a communication mode which is selected by the user through the UI; s7, acquiring the current time period and corresponding geographic position information; s8, detecting whether the acquired time period and geographic position information are consistent with those in the relation table, if so, switching to a direct mode between the D2D terminals, and if not, switching to a communication mode which is automatically selected by a user through a UI. The invention can solve the problem of selecting the D2D terminal communication mode, is more intelligent and improves user experience by dynamically establishing a relation table of D2D terminal mode selection according to a time period, the geographic position of the D2D terminal and the target terminal identification, and selecting whether the traditional cellular communication mode or the direct mode between the D2D terminals according to the relation table when the terminals want to communicate.
