Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the following detailed description of the specific embodiments of the present disclosure will be given with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and the above-described figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order; moreover, embodiments of the present disclosure and features of embodiments may be arbitrarily combined with each other without conflict.
In the following description, suffixes such as "module", "component", or "unit" for representing elements are used only for facilitating the description of the present disclosure, and are not of specific significance per se. Thus, "module," "component," or "unit" may be used in combination.
Currently, indoor distribution systems generally adopt a three-level architecture, namely a baseband unit (Base Baseband Unit, abbreviated as BBU), a convergence unit HUB, and a remote unit (Pico Radio RemoteUnit, abbreviated as PRRU). In order to solve the problem of multiple switching in actual deployment, a plurality of remote units usually belong to the same cell logically although the physical sites are different, and the traffic on each connected remote unit cannot be distinguished on the aggregation unit, so that the traditional indoor distribution system energy-saving scheme mainly uses experience to power down the equipment at fixed time. However, the scheme has poor flexibility, and the situation that no service exists but the equipment still works or the situation that the service exists but the equipment is in a power-down state easily occurs, so that the comprehensive power-saving effect is poor.
In order to solve the problems, the embodiment of the disclosure adopts the hierarchical energy saving mode and combines the far-end unit refinement energy saving mode to optimize the energy saving effect of the indoor distribution system, and in particular, the embodiment of the disclosure judges the service volumes of the baseband unit, the convergence unit and the far-end unit step by step and saves the energy of the indoor system step by step. The service volumes of the baseband unit and the convergence unit can directly acquire data; the remote unit traffic volume acquires the home terminal volume under each remote unit by starting the RSRP reported by the remote unit statistics terminal in turn, so as to acquire the traffic volume.
Referring to fig. 1, fig. 1 is a schematic flow chart of an indoor distribution system energy saving method according to an embodiment of the disclosure, and the method includes steps S101-S106.
In step S101, it is detected whether the data amount of the baseband unit of the indoor distribution system is greater than a first preset threshold, if not, step S102 is executed, otherwise, step S103 is executed.
In this embodiment, the data amount of the base band unit may be directly obtained from the base band unit, and then whether the data amount is less than or equal to a first preset threshold is detected, where the data amount of the base band unit may be a traffic, an uplink/downlink PRB (Physical Resource Block ) utilization, a CCE (Control Channel Element, control channel element) utilization, an RRC (Radio Resource Control ) connection rate, and other parameters capable of reflecting the traffic load.
It should be noted that, the values of the thresholds (e.g., the first preset threshold, the second preset threshold, etc.) in this embodiment may be the same or different, and those skilled in the art may adaptively set the data of the different thresholds in combination with the prior art and the actual application.
In step S102, the baseband unit, the convergence unit of the indoor distribution system, and the plurality of remote units of the indoor distribution system are turned off for energy saving.
Specifically, if the amount of baseband data is detected to be less than or equal to a first preset threshold, e.g., the threshold Γ 1 The baseband unit, the convergence unit and the far-end unit are simultaneously turned off for saving energy; and otherwise, the energy saving is not turned off, and in the embodiment, the energy saving mode aiming at the data volume of the base station is realized, so that the energy saving effect of the micro base station level is maximized.
In step S103, it is detected whether the data amount of the aggregation unit is greater than a second preset threshold, if not, step S104 is performed, otherwise, step S105 is performed.
In this embodiment, parameters such as the data size may be obtained by acquiring the convergence unit data. The acquisition mode can be that data are directly extracted from the aggregation unit, or the data quantity which belongs to the aggregation unit is obtained by a certain method, and then whether the data quantity is smaller than or equal to a second preset threshold value such as a threshold value gamma is detected 2 。
In step S104, the aggregation unit and the plurality of remote units are turned off for energy saving.
In this embodiment, if the aggregation unit detects that the data size is less than or equal to the threshold Γ 2 And if not, the remote units of the aggregation units are not turned off for saving energy, so that the energy saving of the aggregation unit level is realized.
It is understood that a number of remote units refers to all remote units connected to a convergence unit.
In step S105, it is detected whether the respective data amounts of the plurality of remote units are greater than a third preset threshold, if the data amount of one or some of the remote units is not greater than the third preset threshold, step S106 is executed, otherwise, the process is ended, and the energy saving operation for the remote units is completed or the energy saving operation for the remote units is not performed by adopting the prior art.
In an indoor distribution system, a convergence unit is usually connected with a plurality of remote units, and in this embodiment, by detecting the data volume of each remote unit respectively and performing energy-saving turn-off on each remote unit according to a preset rule, the network quality stability during energy saving is ensured while the energy-saving optimization effect is achieved.
Specifically, parameters such as the data size and the like can be obtained through the acquired remote unit data. The acquisition mode may be to directly extract data from the remote unit, or to judge the data amount belonging to the remote unit by a certain method. In some embodiments, by determining the amount of data attributed to the remote unit, the user may be determined by reporting SSB-RSRP (Synchronization Signal Block-Reference Signal Receiving Power, synchronization signal block-reference signal received power) measurement data by the terminal, or by reporting CSI-RSRP (Channel State Information-Reference Signal Receiving Power, channel state information-reference signal received power) measurement data by the terminal, as will be described in detail below.
In step S106, the plurality of remote units are turned off according to a preset rule, so as to save energy.
It should be noted that, in this embodiment, the preset rule is a rule for determining to turn off the power saving or not for the data amount of the plurality of remote units, and in some embodiments, the preset rule is determined according to the neighboring remote units of the remote units. According to the embodiment, the specific energy-saving mode of the remote unit is set, the granularity of the energy-saving equipment is thinned, and the precise energy-saving strategy is realized, so that the energy-saving effect is optimized to the greatest extent.
Referring to fig. 2, a person skilled in the art sets an energy-saving judging period, when entering the energy-saving judging period, step a firstly acquires baseband data, judges whether the baseband data amount/e.g. RRC connection number is less than or equal to 0, and if yes, enters a micro-distribution level to save energy; otherwise, step b, acquiring the data of the aggregation unit, judging whether the data quantity of the aggregation unit/the RRC connection number is less than or equal to 0, and if so, entering the aggregation unit level to save energy; otherwise, step c, obtaining remote unit data, and judging whether the remote unit data volume/e.g. RRC connection number is less than or equal to 0, if so, entering the remote unit level to save energy, otherwise ending or re-detecting until the energy saving judging period is ended.
Referring to fig. 3, fig. 3 is a flow chart of another energy saving method of an indoor distribution system according to an embodiment of the present disclosure, and based on the above embodiment, the embodiment discloses a specific obtaining manner of a remote unit data volume, and specifically, the method further includes, in addition to the steps S101 to S106, the steps of:
in step S301, home terminals corresponding to the plurality of remote units are respectively identified.
In this embodiment, the home terminal is a terminal for calculating the data amount of the remote unit, specifically, as shown in fig. 4, step S301 includes steps S301a-S301e.
Step S301a: sequentially starting the remote units;
step S301b: each time a remote unit is turned on, the respective measurement report values of all terminals in the network that can measure the remote unit signal are obtained, where the measurement report values are obtained by measuring the terminals in the network that can measure the remote unit signal (i.e., the remote unit turned on each time) after receiving an SSB (Synchronization Signal Block ) signal, or a CSI (Channel State Information, channel state information) signal.
Step S301c: sequentially obtaining the reference signal receiving power of all terminals in the network at the plurality of remote units respectively based on the measurement report values obtained each time;
step S301d: respectively identifying corresponding remote units which respectively obtain maximum reference signal receiving power from all terminals in a network based on the reference signal receiving power; the method comprises the steps of,
step S301e: all terminals which obtain the maximum reference signal receiving power at each remote unit are respectively used as home terminals corresponding to the remote units.
It should be noted that, the steps S301a-S301e determine the attribution according to the RSRP measurement result reported by the terminal. The RSRP is one of the methods given in the embodiments, and in some embodiments, the device may further implement, by some method, directly acquiring the remote unit data volume, which is not set in this embodiment.
As shown in fig. 5, a specific implementation of the home terminal of the remote unit is obtained for two different signals, and the flow is as follows:
step 1) after entering a statistical period, acquiring SSB/CSI signals.
Specifically, for different forms of SSB/CSI measurement, configuration parameters are first required, where the terminal reports SSB-RSRP to determine the parameter configuration mode to which the user belongs:
the following parameters are configured in the high-layer CSI-ReportConfig IE:
configuration of CSI reporting period and offset by reportConfigType report type parameter as periodic transmission CSI, reportSlotConfig parameter.
The reportquality parameter is configured as ssb-Index-RSRP.
The terminal reports the CSI-RSRP to judge the parameter configuration mode of the user attribution:
the following parameters are configured in the high-layer CSI-ReportConfig IE
Configuration of CSI reporting period and offset for periodic transmission CSI, reportSlotConfig parameters by reportConfigType parameters
The reportquality parameter is configured as csi-RSRP
The parameter repetition in the higher layer NZP-CSI-RS-ResourceSIE is configured as on
-configuring CSI transmission period and offset by parameter CSI-Resource epoxidizing and offset in higher layer NZP-CSI-RS-Resource IE
Step 2) calculating RSRP.
Specifically, the remote units PRRU are first numbered, prru_index= [0,1, …, N-1]. The remote units PRRU are turned on in turn and the starting system frame number for the remote units PRRU to turn on is calculated.
Since SSB completes transmission within 5ms window in one SS burst set period, the remote units need to turn on in turn according to the SS burst set period, i.e. each SSB period turns on one remote unit, and taking the first system frame number SFN as an example, the starting system frame number prru_sfn_on=sfn+prru_index T turned on by each remote unit is calculated SSB 。
Step 3) find max (prru_index) and return to step 2) when PRRU traversal is not completed.
And 4) after finishing PRRU traversal, judging whether the maximum measurement times in the period are counted. In the statistical period, the maximum measurement times can be set, and each measurement is defined as finishing one PRRU turn-on and terminal reporting.
And 5) counting SSB-RSRP in the SS burst set period corresponding to the opening of each remote unit and reported by each terminal in a counting period to obtain a cell ID, a user ID, PRRU_index and an L1-RSRP mapping table.
Step 6) sorting the RSRP according to the UE ID to obtain max (RSRP), and counting the end of the period by the PRRU_index and UE ID mapping table.
Specifically, using a user ID as a key, ordering L1-RSRP to obtain a set of mapping vectors, using user id=i as an example, [ user i ,vector_RSRP,vector_pRRU,cellID]Wherein
vector_pRRU＝[pRRU 0 ,pRRU 1 ,L,pRRU M-1 ]M is pRRU number of RSRP measured under the userID, M is less than or equal to N; and simultaneously, obtaining a mapping table of M and N, wherein M is M, and N is N. The ordered vector maximizes the RSRP, i.e. max (vector_rsrp) for userid=i, resulting in the corresponding SSB-RSRP measured to be maximumPRRU_index。
In step S302, the data amounts of all the identified home terminals at the remote units to which they belong are acquired, respectively.
In step S303, the data amount of each of the home terminals at the remote units to which the home terminals belong is used as the data amount of each of the plurality of remote units.
Further, to further optimize the energy saving effect of the remote unit, when identifying the home terminal, the step S303 includes the following steps:
and screening all terminals which acquire the maximum reference signal receiving power at each remote unit and have the power value larger than a fourth preset threshold value, and respectively serving as home terminals corresponding to the remote units.
Further, in this embodiment, by dividing adjacent units of the remote units, resource compensation is performed on the corresponding remote units by using the adjacent units, so as to satisfy the communication requirements of the user while rationalizing and saving energy, specifically, after identifying the attributions (i.e. step S301) corresponding to the plurality of remote units, respectively, the terminal further includes the following steps:
for the home terminals corresponding to the remote units, the first remote units with the reference signal receiving power larger than a fourth preset threshold value are screened out from the rest remote units except the home remote units; the method comprises the steps of,
respectively taking first remote units screened out aiming at home terminals corresponding to the remote units as adjacent remote units of the remote units;
the step of turning off the plurality of remote units according to a preset rule for energy saving (i.e. step S106) includes the following steps:
and for the remote units with the data volume not larger than a third preset threshold value, if the sum of the data volume of the remote units and the data volume of the adjacent remote units of the remote units is smaller than a fifth preset threshold value, turning off the remote units for saving energy, and keeping the wake-up state of the adjacent remote units of the remote units.
Can be used forIt is understood that the neighboring remote units determined in this embodiment are co-coverage neighboring remote units, and the reference signal received power RSRP of the first other remote unit is greater than the fourth preset threshold Γ rsrp_prru And is less than the maximum reference signal received power max (RSRP) of its respective remote unit.
Further, in order to meet the compensation effect of the adjacent remote units on the energy-saving remote units and ensure that the adjacent remote units meet the resource requirements of the adjacent remote units, the embodiment further includes the following steps after screening the first remote units for the home terminals corresponding to the plurality of remote units:
continuously screening second remote units with the total number of access terminals greater than a fifth preset threshold value from first remote units screened for home terminals corresponding to the remote units; the method comprises the steps of,
and respectively taking the second remote units screened out aiming at the home terminals corresponding to the remote units as adjacent remote units of the remote units.
In some embodiments, based on the energy-saving manner of the adjacent remote units, a wake-up mechanism is also provided correspondingly, and the wake-up mechanism is used for waking up the adjacent remote units according to a certain rule according to the traffic of the adjacent remote units, which will be referred to later detailed examples and will not be described herein.
In one embodiment, in order to achieve optimization of the energy saving effect and meet the communication quality of the terminal, the embodiment does not save energy in the network coverage while not covering the adjacent area, so as to ensure that the network coverage maintains at least one wake-up state of the remote unit, and specifically, the method further includes the following steps:
for the home terminals corresponding to the remote units, screening out third remote units with reference signal receiving power not more than a fourth preset threshold value from the rest remote units except the home remote units;
respectively taking third remote units screened out aiming at home terminals corresponding to the remote units as non-adjacent remote units of the remote units;
the step of respectively turning off the plurality of remote units according to a preset rule for saving energy comprises the following steps:
the remote units with the data volume not larger than a third preset threshold value are turned off to save energy; and maintaining the wake-up state of non-adjacent ones of the remote units at all times.
It will be appreciated that in this embodiment, there are no neighboring remote units, i.e., there is no coverage of neighboring remote units.
For facilitating understanding of the present embodiment, the present embodiment is exemplified as follows, and as shown in connection with fig. 6, includes a baseband unit 61, a convergence unit 62, and three remote units 63, where the three remote units are respectively identified as pRRU 0 、pRRU 1 And pRRU 2 ，
Firstly, energy saving judgment is carried out

And counting SSB-RSRP in SS burst set periods corresponding to the opening of each remote unit and reported by the terminal to obtain a cell ID, a user ID, pRRU_index and an L1-RSRP mapping table.
RSRP is ordered by user ID, using user id=i as an example, [ user i ,vector_RSRP,vector_pRRU,cell ID]Wherein
And (3) obtaining the maximum value of the ordered vector to the RSRP, namely obtaining max (vector_RSRP) to userID=i, and judging that the terminal belongs to pRRU0 if the corresponding pRRU_index is 0 when the measured SSB-RSRP is the maximum.
1.3.3 energy conservation judgment
Judging the traffic of pRRU0 and pRRU1, if pRRU0 traffic is smaller than Γ 3 The sum of pRRU0 traffic and pRRU1 traffic is below the threshold
Then it is determined that pRRU0 is available for power saving and pRRU1 is not available for power saving as a compensating remote unit.
13.4. A wake-up mechanism is provided to wake up the device,
if remote unit pRRU0 executesAnd the pRRU1 compensates the remote unit for the energy-saving task, and judges whether to wake pRRU0 or not by monitoring the traffic through real-time data. When pRRU1 data size is greater than threshold
When pRRU1 cannot bear the traffic of pRRU 0; or pRRU 1-homing terminal measures that RSRP is below threshold Γ rsrp_low And the number of terminals satisfying the condition is greater than a threshold Γ rsrp_usernum And ending the energy-saving task and waking up pRRU0.
