And under the condition that the terminal equipment meets the first preset condition and the second preset condition, the network equipment increases the RRM measurement period and sends the increased RRM measurement period to the terminal equipment. In the embodiment of the present invention, when the network device determines that the terminal device meets the first preset condition and the second preset condition, the network device can accurately determine that the terminal device is in a stable state (that is, the position and the signal quality of the terminal device are in a stable state, and the initial position of the terminal device is a non-edge position of a cell). Therefore, the terminal equipment can send the RRM measurement data to the network equipment at longer time intervals, the frequency of measuring and reporting the RRM measurement data by the terminal equipment can be reduced, and the energy consumption of the terminal equipment is further reduced.
An RRM measurement method and apparatus provided in an embodiment of the present invention may be applied to a wireless communication system, taking a 5G communication system as an example, as shown in fig. 1, the 5G communication system may include a terminal device 101 and a network device 102, where the terminal device 101 communicates with the network device 102, for example, the network device 102 sends various configuration information (for example, an RRM measurement period) to the terminal device 101, and the terminal device 101 sends data (for example, RRM measurement data) to the network device 102. In general, in practical applications, the connections between the above-mentioned devices or service functions may be wireless connections, and fig. 1 illustrates the connections between the devices by solid lines for convenience of intuitively representing the connections between the devices.
By way of example, taking the network device 102 in fig. 1 as a commonly used base station as an example, a hardware structure of the network device 102 provided in the embodiment of the present invention is described. As shown in fig. 2, a base station provided in an embodiment of the present invention may include: parts 20 and 21. The 20 part is mainly used for receiving and transmitting radio frequency signals and converting the radio frequency signals and baseband signals; the 21 part is mainly used for baseband processing, base station control, and the like. Portion 20 may be generally referred to as a transceiver unit, transceiver, transceiving circuitry, or transceiver, etc. Part 21 is typically the control center of the base station and may be generally referred to as a processing unit.
The transceiver unit of part 20, which may also be referred to as a transceiver, or a transceiver, etc., includes an antenna and a radio frequency unit, or only includes a radio frequency unit or a portion thereof, where the radio frequency unit is mainly used for radio frequency processing. Alternatively, a device for implementing the receiving function in section 20 may be regarded as a receiving unit, and a device for implementing the transmitting function may be regarded as a transmitting unit, that is, section 20 includes a receiving unit and a transmitting unit. A receiving unit may also be referred to as a receiver, a receiving circuit, or the like, and a transmitting unit may be referred to as a transmitter, a transmitting circuit, or the like.
Portion 21 may comprise one or more boards or chips, each of which may comprise one or more processors and one or more memories, the processors being configured to read and execute programs in the memories to implement baseband processing functions and control of the base station. If a plurality of single boards exist, the single boards can be interconnected to increase the processing capacity. As an alternative implementation, multiple boards may share one or more processors, or multiple boards may share one or more memories. The memory and the processor may be integrated together or may be provided separately. In some embodiments, the 20 and 21 sections may be integrated or may be separate. In addition, all functions in the part 21 may be integrated into one chip, or part of functions may be integrated into one chip, so as to implement another part of functions that are integrated into one or more other chips, which is not limited in this embodiment of the present invention.
Illustratively, as shown in fig. 3, a terminal device 30 provided in an embodiment of the present invention includes: a radio frequency front end 301, a transceiving link module 302 and a baseband processing module 303.
The rf front end 301 includes antennas (antenna 1 and antenna 2), an rf switch 3011, a power amplifier 3012, and the like. The power amplifier 3012 is configured to amplify a received signal, and then send the amplified signal to an antenna through the radio frequency switch 3011, where the antenna transmits the signal.
The transceiving link module 302 comprises a receiver 3021, a radio frequency synthesizer 3022, a transmitter 3023, and the like. The receiver 3021 is configured to receive a signal transmitted by an antenna; the radio frequency synthesizer 3022 is configured to generate a local oscillator signal, and perform frequency synthesis on the frequency of the local oscillator signal and a signal at the receiver 3021 or the transmitter 3023; a transmitter 3023 for transmitting the signal to the power amplifier 3012, and at least one analog-to-digital converter (ADC) is present in each of the receiver 3021 and the transmitter 3023, and the ADC is configured to convert the analog signal into a digital signal and further transmit the digital signal to the baseband processing module 303.
And the baseband processing module 303 is configured to process and store data generated by the terminal device during a communication process.
It should be understood that, during the communication process of the terminal device 30, for example, when the terminal device 30 performs RRM measurement (including the process of sending RRM measurement period from the base station to the terminal device and sending RRM measurement data from the terminal device to the base station), the above modules (i.e. the radio frequency front end 301, the transceiving link module 302, and the baseband processing module 303) all generate energy consumption. Specifically, for the rf front end 301, before the terminal device 30 sends out the signal (for example, before the terminal device sends RRM measurement data to the base station), the power amplifier 3012 is required to amplify the signal, and this may cause energy consumption. The transceiver link module 302 also consumes energy because it needs to perform processing such as frequency synthesis on signals. The amount of energy consumption is related to the number of carriers, the number of Multiple Input Multiple Output (MIMO), the bandwidth, and the number of physical resource blocks (PBRs). For the baseband processing module 303, the amount of energy consumption is related to the number of sampling points corresponding to the Fast Fourier Transform (FFT) transformed digital signal and the chip process. Specifically, the larger the number of sampling points, the more energy consumption, and the lower the chip technology, the more energy consumption. Moreover, since the interference and noise processing when the terminal device 30 receives the downlink data needs to be performed in the baseband processing module 303, the energy consumption generated when the baseband processing module 303 processes the downlink data is higher than the energy consumption generated when it processes the uplink data (for example, the energy consumption generated when the terminal device 30 receives the RRM measurement period is higher than the energy consumption generated when the terminal device sends the RRM measurement data).
It should be noted that the energy consumption generated by the above modules is generated by the terminal device 30 during communication with other devices (e.g., base stations). In one case, the terminal device also generates power consumption when it is in a standby state. For example, the Central Processing Unit (CPU), the Graphics Processing Unit (GPU), and the display of the terminal device consume energy in the standby state.
As shown in fig. 4, an RRM measurement method provided in an embodiment of the present invention may include S101 to S105.
S101, the network equipment receives RRM measurement data in the current time period from the terminal equipment.
Wherein the RRM measurement data in the current time period comprises a plurality of RSRPs and a plurality of SINRs.
It should be understood that a plurality of RRM measurement periods may be included in the current time period, and the terminal device may send (or report) RRM measurement data to the network device every RRM measurement period, where the RRM measurement data sent in one RRM measurement period includes one RSRP and one SINR.
S102, the network device determines whether the terminal device meets a first preset condition based on the RRM measurement data in the current time period.
The first preset condition is used for determining that the terminal equipment is located at a non-edge position of the cell.
In an implementation manner of the embodiment of the present invention, the first preset condition is:
|RSRP1-RSRP2|≥N*ΔRSRP；
and/or | SINR1-SINR2|≥N*ΔSINR；
Wherein, RSRP1Representing an average of a plurality of RSRPs over a current time period, RSRP2Representing corresponding RSRP when the terminal equipment is positioned at the edge position of a cell, wherein delta RSRP represents an RSRP threshold decision factor; SINR1Representing an average of a plurality of SINRs over a current time period, SINR2And the corresponding SINR when the terminal equipment is positioned at the edge position of the cell is shown, delta SINR shows an SINR threshold decision factor, N shows a multiple factor, and N is more than or equal to 1.
It should be understood that the corresponding RSRP when the terminal device is located at an edge position of a cell may be an average of RSRPs measured by the terminal device a plurality of times at the edge position of the cell. Similarly, the corresponding SINR when the terminal device is located at the edge position of the cell is an average value of SINRs measured by the terminal device at the edge position of the cell for multiple times.
It will be appreciated that the above-described,the initial position of the terminal device is a non-edge position of the cell. At | RSRP1-RSRP2In the case where | ≧ N × Δ RSRP, it is described that the RSRP corresponding to the terminal device in the current time period (i.e., the average value of multiple RSRPs in the current time period) has a large degree of deviation from the RSRP corresponding to the terminal device at the edge position of the cell, and the network device determines that the terminal device is not at the edge position of the cell, i.e., the terminal device is at a non-edge position of the cell. In this manner, the network device may determine that the location of the terminal device is in a stable state.
Similarly, at the | SINR1-SINR2In the case where | ≧ N × Δ SINR, it is described that the SINR (the average of multiple SINRs in the current time period) corresponding to the terminal device in the current time period greatly deviates from the SINR corresponding to the terminal device at the edge position of the cell, and the network device determines that the terminal device is not at the edge position of the cell, that is, the terminal device is at a non-edge position of the cell. In this way, the network device may also determine that the location of the terminal device is in a stable state.
And S103, the network device determines whether the terminal device meets a second preset condition based on the RRM measurement data in the current time period and the RRM measurement data in the historical time period.
And the second preset condition is used for determining that the signal quality of the terminal equipment in the current time period is in a stable state.
In conjunction with the description of the above embodiments, it should be understood that RRM measurement data in the current time period includes a plurality of RSRPs and a plurality of SINRs. Similarly, the RRM measurement data in the historical period of time, which is a period of time before the current period of time, also includes a plurality of RSRPs and a plurality of SINRs.
In an implementation manner of the embodiment of the present invention, the second preset condition is:
Figure BDA0002571859330000071
and is
Figure BDA0002571859330000072
Wherein, RSRP1Representing an average of a plurality of RSRPs over a current time period, RSRP maxRepresents a maximum value of a plurality of RSRPs within a historical time period, RSRPminRepresenting the minimum value of a plurality of RSRPs in the historical time period, wherein Delta RSRP represents an RSRP threshold decision factor; SINR1Representing an average of a plurality of SINRs within a current time period, SINRmaxIndicating a maximum of a plurality of SINRs within a historical period of time, SINRminThe minimum value of a plurality of SINRs in the historical time period is represented, delta SINR represents an SINR threshold decision factor, N represents a multiple factor, and N is larger than or equal to 1.
It should be understood that,
Figure BDA0002571859330000081
the RSRP corresponding to the terminal device over the historical period of time may be characterized. In that
Figure BDA0002571859330000082
The RSRP of the terminal device in the current time period (i.e., the average value of the RSRPs in the current time period) is less deviated from the RSRP of the terminal device in the historical time period. In the same way, the method for preparing the composite material,
Figure BDA0002571859330000083
the SINR of the terminal device corresponding to the historical period of time can be characterized. In that
Figure BDA0002571859330000084
In the case of (2), it is explained that the SINR corresponding to the terminal device in the current time period (i.e., the average value of the SINRs in the current time period) is less deviated from the SINR corresponding to the terminal device in the past time period.
And under the condition that the network equipment determines that the deviation degree of the RSRP corresponding to the current time period of the terminal equipment and the RSRP corresponding to the historical time period of the terminal equipment is smaller, and the deviation degree of the SINR corresponding to the current time period of the terminal equipment and the SINR corresponding to the historical time period of the terminal equipment is smaller, the network equipment determines that the signal quality of the terminal equipment is in a stable state.
It should be noted that the embodiment of the present invention does not limit the execution sequence of the above S102 and S103. For example, S102 may be executed first and then S103, or S103 may be executed first and then S102, or S102 and S103 may be executed simultaneously.
And S104, under the condition that the terminal equipment meets the first preset condition and the second preset condition, the network equipment increases the RRM measurement period.
In the embodiment of the present invention, when the network device determines that the terminal device is located at the non-edge position of the cell and the signal quality of the terminal device is in the stable state in the current time period, the network device can accurately determine that the terminal device is in the stable state (that is, the position of the terminal device and the signal quality are in the stable state), so that the network device increases the RRM measurement period.
In an implementation manner of the embodiment of the present invention, when the network device determines that the terminal device does not satisfy the first preset condition and/or the second preset condition, the network device determines that the RRM measurement period does not need to be increased, that is, the terminal device continues to measure in the RRM measurement period before the increase and reports RRM measurement data.
And S105, the network equipment sends the increased RRM measurement period to the terminal equipment.
In an implementation manner of the embodiment of the present invention, the increased RRM measurement period satisfies:

and the variance of the RSRP in the historical time period is represented, and the Δ RSRP represents an RSRP threshold decision factor.
It should be understood that the network device may determine the multiple of the increase in RRM measurement period, i.e., the RSRP threshold decision factor and the variance of SINR over the historical period of time, or the variance of RSRP over the historical period of time

In this way, the network device increases the RRM measurement period and transmits the increased RRM measurement period to the terminal device when the terminal device satisfies the first preset condition and the second preset condition. In the embodiment of the present invention, when the network device determines that the terminal device meets the first preset condition and the second preset condition, the network device can accurately determine that the terminal device is in a stable state (that is, the position and the signal quality of the terminal device are in a stable state, and the initial position of the terminal device is a non-edge position of a cell). Therefore, the terminal equipment can send the RRM measurement data to the network equipment at longer time intervals, the frequency of measuring and reporting the RRM measurement data by the terminal equipment can be reduced, and the energy consumption of the terminal equipment is further reduced.
As shown in fig. 5, in an implementation manner, an RRM measurement method provided in an embodiment of the present invention includes S201 to S206:
s201, the network device receives RRM measurement data in the current time period from the terminal device.
S202, the network device determines, based on the RRM measurement data in the current time period and the RRM measurement data in the historical time period, whether the terminal device satisfies a second preset condition.
It should be understood that the explanation of S201-S202 can refer to the description in S101-S102, and the description is omitted here.
S203, the network equipment acquires the current moving speed of the terminal equipment.
In one implementation manner of the embodiment of the present invention, the terminal device may detect (or test) its current moving speed, and send the moving speed to the positioning device, and the positioning device sends the moving speed to the network device.
And S204, the network equipment determines whether the terminal meets a third preset condition according to the current moving speed of the terminal equipment.
And the third preset condition is used for determining that the moving speed of the terminal equipment is in a stable state.

V2-ΔV≤V1≤V2+ΔV；
wherein, V1Indicating the current moving speed, V, of the terminal device 2Representing the critical moving speed, and av represents the moving speed threshold decision factor.
It can be understood that the initial moving speed of the terminal device is the critical moving speed, and the threshold-moving-speed decision factor is set for the terminal deviceAnd (4) a moving speed error value. The network device may determine a minimum travel speed value (i.e., V) based on the initial travel speed and the travel speed error value2Δ V) and maximum moving speed (i.e., V)2+ Δ V), i.e. a reasonable range for determining the speed of movement. And under the condition that the network device determines that the current moving speed of the terminal device is greater than or equal to the minimum moving speed and less than or equal to the maximum moving speed (namely, the current moving speed of the terminal device is within a reasonable range of the moving speed), the network device determines that the moving speed of the terminal device is in a stable state (namely, the terminal device meets a third preset condition). And under the condition that the network device determines that the current moving speed of the terminal device is smaller than the minimum moving speed or larger than the maximum moving speed (namely, the current moving speed of the terminal device is out of a reasonable range of the moving speed), the network device determines that the current moving speed of the terminal device is in an unstable state (namely, the terminal device does not meet a third preset condition).
It should be noted that the embodiment of the present invention does not limit the execution sequence of the above S202 and S204. For example, S202 may be performed first and then S204 may be performed, or S202 and S204 may be performed simultaneously.
And S205, under the condition that the terminal equipment meets the second preset condition and the third preset condition, the network equipment increases the RRM measurement period.
In the embodiment of the present invention, when the network device determines that the signal quality of the terminal device in the current time period is in the stable state and the moving speed of the terminal device is in the stable state, the network device can accurately determine that the terminal device is in the stable state (that is, the moving speed and the signal quality of the terminal device are in the stable state), so that the network device increases the RRM measurement period.
In an implementation manner of the embodiment of the present invention, when the network device determines that the terminal device does not satisfy the second preset condition and/or the third preset condition, the network device determines that the RRM measurement period does not need to be increased, that is, the terminal device continues to measure in the RRM measurement period before the increase and reports RRM measurement data.
And S206, the network equipment sends the increased RRM measurement period to the terminal equipment.
It should be understood that, after the terminal device receives the increased RRM measurement period sent by the network device, the terminal device performs RRM measurement according to the increased RRM measurement period (i.e., measures and reports RRM measurement data).
In the embodiment of the invention, network equipment receives RRM measurement data in the current time period from terminal equipment; the network device determines whether the terminal device meets a second preset condition based on the RRM measurement data in the current time period and the RRM measurement data in the historical time period, where the second preset condition is used to determine that the signal quality of the terminal device in the current time period is in a stable state; and then the network equipment acquires the current moving speed of the terminal equipment, and determines whether the terminal meets a third preset condition according to the current moving speed of the terminal equipment, wherein the third preset condition is used for determining that the moving speed of the terminal equipment is in a stable state. In this way, when the terminal device satisfies the second preset condition and the third preset condition, the network device increases the RRM measurement period and transmits the increased RRM measurement period to the terminal device. In the embodiment of the present invention, when the network device determines that the terminal device meets the second preset condition and the third preset condition, the network device can accurately determine that the terminal device is in a stable state (that is, the moving speed and the signal quality of the terminal device are in a stable state, and the current moving speed of the terminal device is within a reasonable range of the moving speed). Therefore, the terminal equipment can send the RRM measurement data to the network equipment at longer time intervals, the frequency of measuring and reporting the RRM measurement data by the terminal equipment can be reduced, and the energy consumption of the terminal equipment is further reduced.
In another implementation, the network device may further preset an increase multiple of the measurement period, where the increase multiple is denoted by M, and M is greater than or equal to 1, and the RRM measurement period before the increase is the first RRM measurement period, and the RRM measurement period after the increase is the second RRM measurement period, and then the second RRM measurement period is the first RRM measurement period that is M times. The terminal device may perform the RRM measurement according to the second RRM measurement period. The method specifically comprises the following steps of 1-3:
step 1, the network device receives RRM measurement data measured by the terminal device according to the second RRM measurement cycle in the first period and RRM measurement data measured by the terminal device according to the second RRM measurement cycle in the second period from the terminal device.
In conjunction with the description of the above embodiments, it is understood that the first time period may correspond to the above-described historical time period, and the second time period may correspond to the above-described current time period, the first time period being a period of time before the second time period. Similarly, the RRM measurement data in the first time period corresponds to the RRM measurement data in the historical time period, and the RRM measurement data in the second time period corresponds to the RRM measurement data in the current time period.
And step 2, the network device determines whether the terminal device meets a first preset condition based on the RRM measurement data measured by the terminal device in the second RRM measurement period in the second time period, and determines whether the terminal device meets a second preset condition based on the RRM measurement data measured by the terminal device in the second RRM measurement period in the first time period and the RRM measurement data measured by the terminal device in the second RRM measurement period in the second time period.
And 3, under the condition that the terminal device meets the first preset condition and the second preset condition, the network device determines that the second RRM measurement period is a reasonable RRM measurement period, that is, M is a reasonable increase multiple, otherwise, the network device determines that the second RRM measurement period is unreasonable, that is, the second RRM measurement period is long, and the value of M is too large.
If the network device determines that the second RRM measurement period is reasonable, the network device sends the second RRM measurement period to the terminal device, so that the terminal device measures and reports RRM measurement data according to the second RRM measurement period. Optionally, in an implementation manner, in the process of performing the RRM measurement subsequently, the network device may further continue to increase the RRM measurement period, that is, continue to increase the M, on the basis of the second RRM measurement period according to an actual situation, and determine whether the increased RRM measurement period is reasonable according to the methods in the foregoing step 1 to step 3.
If the network device determines that the second RRM measurement period is not reasonable, the network device decreases the RRM measurement period, that is, decreases the value of M, on the basis of the second RRM measurement period, and determines whether the decreased RRM measurement period is reasonable according to the methods in the above steps 1 to 3 until the reasonable RRM measurement period is determined, and sends the reasonable RRM measurement period to the terminal device, and the terminal device measures and reports RRM measurement data according to the reasonable RRM measurement period.
Similarly, referring to the foregoing S201 to S205, the network device may further determine whether the second RRM measurement period is a reasonable RRM measurement period based on a second preset condition and a third preset condition, which is not described herein again.
