Embodiment approach

[0041] An implementation manner of detecting the link quality indicator value is as follows:

[0042] The reliable transmission probability at a certain moment is defined as the probability that the signal-to-noise ratio at this moment is greater than the threshold κ. Since the movement trajectory of the terminal can be predicted, set t 0 At the moment, the terminal is in two network nodes υ p , υ q Heavy coverage area, i.e. τs q ≤t 0 ≤τe p , according to the satellite distribution map of the whole network, select the distance t 0 Before the time around the terminal position users nearby, extract their connections to υ from the network information database p , υ q The signal-to-noise ratio SINR of the communication link, will be before SINR of the nearest user as terminal t 0 Always connect to υ p or υ q The predicted value of the link signal-to-noise ratio SINR, namely

[0043] During the process of traveling, the terminal periodically monitors the communicati...

Abstract

The present invention provides a multi-dimensional complex network self-healing system with high reliability. The system includes: a terminal detection module for detecting network status information; a network terminal detection module for re-determining the interruption of the cell where the terminal is located; a network handover prediction module , used to determine the coverage state of the network node to the terminal in each time slot, and confirm whether there will be a network handover due to the limited coverage of the node according to the coverage state; the network compensation module is used to receive the network detection module according to The detection result is used to perform network compensation; the network switching module is used to prepare for network switching, and to perform network switching after receiving an invalid result from the network compensation module. The system can handshake with the predicted switching network node in advance to realize resource reservation and effectively ensure the continuity of end-user communication. Double-ended detection and parallel network compensation and handover preparation are adopted to ensure the continuity of communication and reduce the network recovery delay.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a high-reliability multi-dimensional complex network self-healing system. Background technique [0002] As one of the most important functions in the field of mobile communication, network self-healing can autonomously detect sudden failures in the network, reduce maintenance costs, and eliminate the impact of the failure through a series of adjustment measures, thereby maintaining various functions provided by the network. Its performance is closely related to service quality and end-user experience. At this stage, the research on the self-healing technology of mobile communication systems still faces many challenges. First, since the self-healing system needs to know the information of other network nodes, the relevant decision module first needs to collect the information of all adjacent network nodes, which will increase the delay to a certain extent. ...
