Embodiment approach 1

[0159] Embodiment 1: Among the same positions in the first movement trajectory and the second movement trajectory, there is at least one overlapping duration corresponding to a position greater than the preset duration. For example, suppose UE1's movement trajectory is cell 1→cell 2→cell 3, UE2's movement trajectory is cell 4→cell 2→cell 5, and UE1 is in cell 2 from 8:00 to 9:00, UE2 is in The time of cell 2 is from 8:30 to 9:15, then UE1 and UE2 have the same location cell 2 in their respective moving trajectories, and the overlapping duration of UE1 and UE2 in this cell 2 is 30 minutes (that is, 8: 30 to 9:00), which is greater than the preset duration (assumed to be 10 minutes), therefore, the NWDAF network element may determine that the overlapping duration corresponding to the same position in the movement trajectories of UE1 and UE2 is greater than the preset duration.

Embodiment approach 2

[0160] Embodiment 2: The same positions in the first movement track and the second movement track include consecutive same positions (that is, the first terminal and the second terminal continuously have the same position change), and there are The overlap duration corresponding to at least one location is greater than a preset duration. For example, UE1's movement trajectory is cell 1→cell 2→cell 3→cell 4→cell 5, UE2's movement trajectory is cell 6→cell 2→cell 3→cell 4→cell 7, then UE1 and UE2 correspond to the movement There are consecutive identical positions cell 2, cell 3, and cell 4 in the trajectory. When the overlapping duration between UE1 and UE2 in any cell or multiple cells in cell 2, cell 3, and cell 4 is longer than the preset duration, the NWDAF network element It may be determined that the overlapping duration corresponding to the same position in the movement trajectories of UE1 and UE2 is greater than a preset duration.

Embodiment approach 3

[0161] Embodiment 3: The same position in the first movement track and the second movement track includes multiple positions, and the sum of the overlapping durations corresponding to each position is greater than the preset duration. For example, suppose UE1's movement trajectory is cell 1→cell2→cell 3, UE2's movement trajectory is cell 4→cell 2→cell 3, and the time UE1 is in cell 2 and cell3 is from 8:00 to 9:00, From 9:00 to 10:00, UE2 is in cell 2 and cell3 from 8:30 to 9:15, and from 9:15 to 10:30 respectively, then there is the same location cell 2 in the movement trajectories corresponding to UE1 and UE2 respectively , cell3, and the overlapping duration of UE1 and UE2 in the cell 2 is 30 minutes (that is, 8:30 to 9:00), and the overlapping duration in cell 3 is 45 minutes (that is, 9:15 to 10:00) , that is, the sum of the overlapping durations of UE1 and UE2 in cell 2 and cell 3 is 75 minutes, which is greater than the preset duration (assumed to be 60 minutes).

Abstract

The invention discloses a communication method, device and system, and the method comprises the steps that: a data analysis network element obtains the information of a first movement track, the information of the first movement track comprises the information of a first position and the information of time corresponding to the first position, and determines that a second movement track of a second terminal intersects with the first movement track, and an analysis result is sent to the first network element, the analysis result comprising any one or more of the following information: identification information of a second terminal, the number, an information analysis result of a second movement track, an activeness analysis result, a risk analysis result, and an information analysis result of a third movement track, wherein the third movement track includes at least a portion of an overlapping trajectory between the first movement trajectory and the second movement trajectory. And the data analysis network element obtains the information of the analysis result of the second terminal corresponding to the second movement track which has the intersection with the first movement track. The detection efficiency can be improved, and the possibility of errors can be reduced.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method, device and system. Background technique [0002] In view of the current outbreak of emergencies, in order to obtain user information related to the emergency, information collectors need to go offline to check the information of relevant users in contact with the emergency. For example, in order to check users related to emergency events, information collectors need to go door-to-door to register whether users are related to emergency events in a certain area at a certain time. In this method, information collectors can obtain whether users are related to emergency events through offline information collection, which is inefficient and error-prone. Contents of the invention [0003] The embodiment of the present application provides a communication method, device and system to timely determine user-related information related to emer...
