Problems solved by technology

[0005] The serving cell and the optimal neighboring cell in the existing technical solutions are only based on RSRP or RSRQ (RSRQ is rarely used), which leads to VOLTE-related indicators that cannot accurately meet the network requirements, especially the lack of an evaluation mechanism for the perception dimension of the serving cell, resulting in the failure of the serving cell When the above problems occur, it cannot be switched to the optimal neighboring cell in time, which increases the risk of user packet loss, intermittent, one-way, call drop, and poor MOS value. At the same time, there is a lack of evaluation mechanism for the perception dimension of the target cell, which leads to the above problems in the target cell It still cuts in at any time, increasing the risk of user packet loss, intermittent, single call, call drop, and MOS value difference

Abstract

The invention belongs to the technical field of communication, and discloses a VoLTE accurate switching method and system based on user perception, and the method comprises the steps: determining a KPI index and a convergence threshold of a perception dimension through the hierarchical mapping of a KQI and a KPI index according to the perception dimension of a user, building a KPI difference portrait model, and carrying out the comprehensive scoring of a small service and a target cell; if the total weight score of the serving cell exceeds the total weight score of the neighbor cell, startingan emergency switching process; and when the serving cell does not reach the condition of starting the emergency switching threshold, namely the total weight score is smaller than the total weight score of the adjacent cell, performing pilot frequency inter-system switching based on A2 + A4 / A2 + A5 / A2 + B2 according to a normal switching process. According to the invention, the emergency switchingof the perception dimension is introduced to enable the UE terminal to quickly start the emergency switching when the perception of the serving cell is reduced, thereby effectively avoiding the problems of packet loss, interruption, single pass, call drop and poor MOS quality caused by the degradation of the UE terminal in the aspects of interference, quality, load, distance and the like in the prior art, and improving the voice quality.

Description

Technical field[0001]The present invention relates to the field of 4G communication technology, and in particular to a method and system for precise VoLTE handover based on user perception.Background technique[0002]A cell with good network quality is the most important condition to ensure a good perception of VoLTE users. As the network environment changes during the user's movement, precise mobility strategies are particularly important. The existing technical solutions perform algorithm statistics based on the interoperability parameters of the serving cell and neighboring cells (24G handover, inter-frequency handover, etc.). When the terminal measures the serving cell level below the specified threshold and the adjacent cell level is higher than the specified threshold, the inter-cell is completed Switch between different frequencies and different systems.[0003]Inter-frequency handover in the VOLTE system: Handover from a low-priority cell to a high-priority cell, using the A2+A4...
