detailed description

To make the objectives, technical solutions, and advantages of the present disclosure more clear, the embodiments of the present disclosure will be described in further detail below in conjunction with the accompanying drawings.

3GPP carried out research on terminal power saving in the second version of 5G. Power saving includes multiple aspects: connection state control channel detection optimization, optimized terminal discontinuous reception process control, and reduced measurement requirements for radio resource management Wait.

Among them, the measurement frequency and measurement period in the measurement requirements for radio resource management are all for all terminals, that is, mobility is not distinguished. In order to achieve the purpose of power saving by reducing the measurement requirements of radio resource management, two types of terminal mobility states are classified: normal mobility state and low mobility state. Correspondingly, the measurement requirements of radio resource management include Measurement configuration for normal mobility and measurement configuration for low mobility. Compared with the measurement configuration of normal mobility, the measurement requirement of the low mobility is reduced, so that the power consumption of the terminal in the low mobility state is reduced.

The network structure in the communication system is shown in FIG. 1. The macro cell 101 (a cell provided by a macro base station) is used as a skeleton, and the micro cell 102 (a cell provided by a micro base station/pico base station) is a supplementary and hot spot coverage architecture. The macro cell 101 is characterized by a large coverage area, and the micro cell 102 has a small coverage area. When the terminal moves back and forth according to arrow 103, cell reselection or handover may occur according to the change in signal strength. However, if the terminal remains stationary or the movement range is small, if the mobility is not distinguished, the measurement configuration of normal mobility is always used for measurement, which consumes a lot of unnecessary measurements, resulting in the consumption of terminal power. Therefore, in this case, defining a low-mobility measurement configuration corresponding to the low-mobility state of the terminal can reduce unnecessary measurement consumption, thereby achieving power saving.

Embodiments of the present disclosure provide a signal quality measurement method, device, and equipment. The terminal determines whether the terminal is in a low mobility state according to the measured signal strength of n cells. When the terminal determines that it is in a low mobility state, the terminal performs low mobility measurement, thereby reducing power consumption of the terminal by the cell signal quality measurement process.

FIG. 2 shows a schematic diagram of an implementation environment when a terminal is in a low mobility state according to an exemplary embodiment of the present disclosure. FIG. 2 takes the terminal performing mobility measurement within the coverage of 3 cells as an example. FIG. 2 Including: terminal 201, first cell 202, second cell 203 and third cell 204.

The terminal 201 is used to change the signal strength of three cells in the range in which the terminal 201 moves back and forth within a predetermined measurement period. The terminal 201 is configured to use a low mobility measurement configuration to perform measurement when it is determined that the terminal 201 itself is in a low mobility state.

It is assumed that the first cell 202 is a camping cell of the terminal, and the access network device of the first cell 202 is used to send the signal strength thresholds corresponding to the three cells to the terminal.

It is assumed that the second cell 203 is a camping cell of the terminal, and the access network device of the second cell 203 is used to send the signal strength thresholds corresponding to the three cells to the terminal.

It is assumed that the third cell 204 is a camping cell of the terminal, and the access network device of the third cell 204 is used to send the signal strength thresholds corresponding to the three cells to the terminal.

In an optional implementation manner, when the signal strength of n cells is greater than the first signal strength threshold corresponding to n cells, the terminal determines that the terminal itself is in a low mobility state within a predetermined time.

In another optional embodiment, the signal strength of the terminal in n cells is respectively greater than the first signal strength threshold corresponding to n cells, and the signal strength threshold of n cells is smaller than the second signal corresponding to n cells, respectively At the strength threshold, it is determined that the terminal itself is in a low mobility state within a predetermined time.

Optionally, after determining that it is in a low mobility state, the terminal switches the measurement configuration in effect from the first measurement configuration corresponding to normal mobility to the second measurement configuration corresponding to low mobility. Compared with the second measurement configuration with normal mobility, the second measurement configuration with low mobility reduces the number of measurement frequency points, and/or the measurement period is extended, so that when the terminal is in a low mobility state, the relevant cell signal The power consumption generated by the quality measurement process is reduced to achieve the purpose of saving electricity.
