Embodiment Construction

[0041] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0042] figure 2 It shows a schematic flowchart of a CQI information-based quality switching processing method provided in this embodiment, including:

[0043] S201. Acquire CQI information reported by a terminal.

[0044] Among them, CQI (Channel Quality Indicator, channel quality indication) is the measurement standard of the communication quality of the wireless channel. The UE sends the CQI to the eNB on the PUCCH / PUSCH, and the eNB obtains the CQI value, which represents the quality of the current PDSCH wireless channel condition. . CQI can represent the so-called value (or multiple values) of the channel measurement standard of a given channel. CQI is used to...

Abstract

The embodiment of the invention discloses a quality switching processing method and device based on CQI (Channel Quality Indicator) information. The method comprises the following steps: acquiring CQIinformation reported by a terminal; if it is judged that the proportion of the terminal with the sampling point proportion of the CQI information larger than a first preset value to all the terminalsin the current cell is larger than a second preset value, determining that the user quality of the current cell becomes poor, and starting switching based on quality; and determining that the user quality of the current cell becomes better and closing quality-based switching if it is judged that the proportion of the terminal of which the sampling point proportion of the CQI information is greater than the first preset value to all terminals of the current cell is less than a third preset value. According to the embodiment of the invention, the user quality of the current cell is determined by judging the proportion of the sampling points of the CQI information, and the switching based on the quality is determined to be started or stopped, so that the monitoring of the quality of the target cell is increased, the user perception can be better improved, and the practicability is very good.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mobile communication, and in particular to a method and device for quality handover processing based on CQI information. Background technique [0002] After VoLTE is deployed, in order to ensure the UE's VoLTE voice experience, the eNodeb should monitor the voice quality of each UE. If the voice quality is poor to a certain extent, it will trigger intra-system inter-frequency handover or inter-system SRVCC to improve user experience. Speech awareness. [0003] In the case of a weak field, the voice quality may change at any time, and it is necessary to define a good threshold of the voice quality to terminate the inter-frequency handover and SRVCC process triggered by the voice quality. In terms of implementation, the poor threshold and good threshold of the downlink MCS are added to represent the worse threshold and the better threshold of the downlink voice quality respectivel...
