The symbol "/" herein denotes a relationship in which the associated object is or, for example, a/B denotes a or B.
The embodiment of the invention provides a method for reducing cell volume, wherein an execution subject of the method can be a device for reducing cell volume, and the device can be access network equipment. For example, the access network device may be a base station or an evolved base station in practical applications.
As shown in fig. 1, an embodiment of the present invention provides a method for cell volume reduction, which may include the following steps S101 to S109.
S101, collecting statistical data of cell traffic.
In the embodiment of the invention, the statistical data of the cell traffic can be collected through the base station providing service for the cell.
In the embodiment of the present invention, the service of the cell may include a voice service and a data service. The statistics of the cell traffic may include voice traffic and data traffic equivalent traffic.
Illustratively, the voice service may include a conventional voice service (e.g., a call), and may also include a short message service. The data service may include multimedia message, internet access, etc.
Therefore, when the cell reduction method provided by the embodiment of the invention is applied to a cell with a network standard of GSM, the voice service traffic may refer to TCH traffic (i.e. traffic for transmitting voice service through TCH), and the data service equivalent traffic may refer to PDCH data equivalent traffic (i.e. traffic for transmitting data service through TCH).
It should be noted that, generally, the PDCH data equivalent traffic is defined as: and accumulating and counting the occupation duration of the PDCH within an hour measurement period, and after the counting period is finished, dividing the accumulated value by 3600 to obtain the number of the PDCH (including the dynamic PDCH number and the static PDCH number) occupied within the measurement period, namely the equivalent traffic of PDCH data.
In the embodiment of the invention, when the statistical data of the cell traffic is collected, a plurality of voice service traffic and a plurality of data service equivalent traffic can be collected. For example, the embodiment of the present invention may collect the voice service traffic and the data service equivalent traffic of each hour in N days of the cell, or may collect the voice service traffic and the data service equivalent traffic of a busy hour in N days of the cell. Optionally, N days in the embodiment of the present invention may be at least two days. Illustratively, the above N days may be 30 days.
S102, acquiring a reference value of the voice service telephone traffic according to the statistical data of the voice service telephone traffic in the statistical data of the cell service traffic.
In the embodiment of the present invention, the reference value of the voice service telephone traffic may be an average value of a plurality of voice service telephone traffic, or a value calculated according to a ratio of the average value of the plurality of voice service telephone traffic to a preset telephone traffic allowance.
Optionally, in this embodiment of the present invention, the reference value of the voice service traffic may also be a maximum value in the multiple voice service traffic, or a value calculated according to a ratio of the maximum value in the multiple voice service traffic to a preset traffic margin.
Optionally, in this embodiment of the present invention, the average value of the multiple voice traffic volumes may be an average value of the voice traffic volumes when the N days (for example, 30 days) are busy.
Illustratively, it can be based on a formula
And calculating a reference value of the voice service traffic. Wherein A represents a reference value of voice service traffic volume, AvaveRepresents the average of the voice traffic volume for an N-day (e.g. 30-day) busy hour,
and (4) presetting a traffic allowance proportion for an operator.
S103, acquiring the number of voice service channels to be configured according to the reference value of the voice service telephone traffic.
In the embodiment of the present invention, the above S103 may be implemented according to the following S103a and S103 b:
s103a, according to the reference value of the voice service telephone traffic and the call loss rate of the cell, inquiring the Ireland B table to obtain the theoretical voice service channel number of the cell.
For example, in the embodiment of the present invention, the number of theoretical voice service channels may be obtained by querying an ireland B table according to the reference value a of the voice service traffic and the call loss rate corresponding to the type of the administrative domain to which the cell belongs. The call loss rates corresponding to different types of administrative regions to which the cells belong are different in the Ireland B table.
Optionally, the type of the administrative area to which the cell belongs may be obtained by obtaining basic configuration data of the cell.
S103b, calculating the number of voice service channels needed to be configured in the cell according to the theoretical number of voice service channels and the preset half rate ratio.
In an actual network, in order to avoid the congestion of a voice service channel and guarantee the voice service quality, the resource utilization rate of the voice service cannot exceed a certain threshold, namely a certain capacity margin needs to be considered, and in order to improve the capacity carrying capacity, the operator needs to start a half-rate function on the base station side, so that the purpose of improving the single carrier telephone traffic carrying capacity can be achieved. The half rate on ratio may be determined by the operator based on network load conditions.
Illustratively, the following may be expressed according to a relation (which may be referred to as relation 1): the number of voice service channels to be configured is equal to the theoretical number of voice service channels/(1 + r), and the number of voice service channels meeting the service volume requirement after the half-rate opening ratio is considered in calculation, that is, the number of voice service channels to be configured in the cell. Where r represents the half rate turn-on ratio preset by the operator.
S104, acquiring a reference value of the data service equivalent telephone traffic according to the statistical data of the data service equivalent telephone traffic in the statistical data of the cell service traffic.
In the embodiment of the present invention, the reference value of the data service equivalent telephone traffic may be an average value of a plurality of data service equivalent telephone traffic.
Optionally, the reference value of the data service equivalent traffic volume in the embodiment of the present invention may also be a maximum value in the plurality of data service equivalent traffic volumes.
Optionally, the average value of the data traffic equivalent traffic volumes is an average value of data traffic equivalent traffic volumes when the number of data traffic equivalent traffic volumes is busy for N days (for example, 30 days).
And S105, acquiring the number of data service channels to be configured according to the reference value of the data service equivalent telephone traffic.
In an actual network, in order to avoid congestion of a data service channel and guarantee data service quality, an operator needs to consider a certain capacity margin because the resource utilization rate of the data service cannot exceed a certain threshold, and the operator needs to preset an equivalent traffic margin ratio in order to improve capacity carrying capacity. Therefore, in the embodiment of the present invention, the number of data service channels to be configured in the cell may be calculated according to the reference value of the data service equivalent traffic and the preset equivalent traffic margin ratio.
Illustratively, the following may be expressed according to a relation (which may be referred to as relation 2): and calculating the number of the data service channels to be configured for the cell, wherein the number of the data service channels to be configured is equal to the reference value/(1-phi) of the data service equivalent telephone traffic. Wherein Φ is an equivalent telephone traffic allowance proportion preset by an operator.
It should be noted that, in the embodiment of the present invention, the execution sequence of S102 to S103 and S104 to S105 is not limited, that is, in the embodiment of the present invention, S102 and S103 may be executed first, and then S104 and S105 may be executed; s104 and S105 may be executed first, and then S102 and S103 may be executed; it is also possible to perform the above-described S102-S103 and S104-S105 simultaneously.
S106, acquiring the carrier frequency number to be configured of the cell according to the sum of the voice service channel number to be configured and the data service channel number to be configured.
In the embodiment of the invention, the number of voice service channels to be configured and the number of data service channels to be configured can be summed to obtain the total number of service channels to be configured for the cell, and then the number of carrier frequencies to be configured for the cell can be obtained according to the total number of service channels to be configured for the cell.
Considering that in an actual network, each cell may configure 1 Broadcast Control Channel (BCCH), configure a number of independent dedicated control channels (SDCCH) that is half of a number of carrier frequencies that the cell needs to configure, and then round up again, and neither the BCCH nor the SDCCH can transmit traffic. Thus, for example, in the embodiment of the present invention, the following relationship (which may be referred to as relationship 3) may be used: and obtaining the corresponding relation between the number of the carrier frequencies to be configured and the total number of the service channels to be configured by 8-1-ROUNDUP (the number of the carrier frequencies to be configured/2). Wherein, ROUNDUP (number of carrier frequencies to be configured/2) means rounding up after dividing the number of carrier frequencies to be configured by 2.
For example, a corresponding relationship table of the number of carrier frequencies to be configured and the channel configuration shown in table 1 can be obtained according to the above relationship 3.
TABLE 1
Then, the number of carrier frequencies to be configured can be determined according to the table 1 and the total number of the service channels to be configured. It can be seen that when the total number of the service channels to be configured is 1-6, the number of the carrier frequencies to be configured is 1; when the total number of the service channels to be configured is 7-14, the number of the carrier frequencies to be configured is 2; when the total number of the service channels to be configured is 15-21, the number of the carrier frequencies to be configured is 3; when the total number of the service channels to be configured is 22-29, the number of the carrier frequencies to be configured is 4.
S107, judging whether the number of carrier frequencies needed to be configured in the cell is smaller than the number of carrier frequencies actually configured in the cell.
After the number of carrier frequencies to be configured for the cell is determined according to the above S106, it may be determined whether the number of carrier frequencies to be configured for the cell is smaller than the number of carrier frequencies actually configured for the cell, where the number of carrier frequencies to be configured for the cell is smaller than the number of carrier frequencies actually configured for the cell, S108 is performed, and where the number of carrier frequencies to be configured for the cell is greater than or equal to the number of carrier frequencies actually configured for the cell, the original carrier frequency resources of the cell are kept unchanged, that is, S109 is performed.
S108, closing part of carrier frequency resources of the cell.
And the number of the carrier frequencies left by the cell after the carrier frequency resources are closed is greater than or equal to the number of the carrier frequencies to be configured.
Optionally, in the embodiment of the present invention, a part of carrier frequency resources of the cell may be closed according to the reducible carrier frequency number of the cell, so that the remaining carrier frequency number of the cell after closing the carrier frequency resources may be equal to the carrier frequency number to be configured. The capacity-reduced carrier frequency number is the difference between the actually configured carrier frequency number and the carrier frequency number to be configured.
S109, the original carrier frequency resource of the cell is kept unchanged.
In the embodiment of the invention, the original carrier frequency resource of the cell is kept unchanged, the actually configured carrier frequency number of the cell can be kept without adjusting the actually configured carrier frequency number of the cell.
The cell volume reduction method provided by the embodiment of the invention can acquire the number of carrier frequencies required to be configured by the cell according to the statistical data of the cell traffic; and under the condition that the number of carrier frequencies to be configured is less than the number of carrier frequencies actually configured by the cell, partial carrier frequency resources of the cell can be closed; and the number of the carrier frequencies left by the cell after the carrier frequency resources are closed is greater than or equal to the number of the carrier frequencies to be configured. Thus, when the cell capacity reduction method provided by the embodiment of the invention is adopted to adjust (close) the cell carrier frequency number, the cell with excessive actually configured carrier frequency number can be subjected to capacity reduction (close part of carrier frequency resources) according to the requirement of the cell on the carrier frequency number, so that the waste of the carrier frequency resources can be avoided.
