Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular, to a network frequency coordination method and apparatus based on macro and micro sector service absorption. Background Art

[0002] With the rapid development of mobile network technologies, people's demand for mobile communication services, especially for data services, has increased sharply, which poses challenges to existing communication systems. In order to meet users' demands for higher communication rates, shorter communication delays, and more communication connections, 5G technology has emerged. Based on the frequency band configuration of the current mobile 4G network deployment, there is interference between the frequency bands of 4G and 5G. How to ensure the quality of the 4G network while doing a good job in the frequency coordination of 4G / 5G is an urgent problem to be solved currently.

[0003] There are mainly two existing 4G / 5G frequency coordination technical solutions: The first solution is to directly de-frequency the D1 / D2 carriers of the existing 4G network in the 4G area; the second solution is to perform a 1:1 capacity replacement on the D1 / D2 carriers of the existing 4G network in the 4G area. However, adopting the first solution will have a great impact on the quality of the 4G network under high load. When de-frequencying directly without the capacity being supplemented, the user page rate drops by 44%, and the high-load cell rises by 60%. The second solution does not comprehensively consider the redundancy of the capacity of some existing 4G sites and the impact of 5G backhaul on 4G capacity, which will cause waste of investment. At the same time, a large number of capacity replacement equipment procurement projects also require a relatively long cycle, which will affect the progress of 4G / 5G frequency coordination. Summary of the Invention

[0025] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0026] Figure 1The flowchart of the network frequency coordination method based on macro and micro sector traffic absorption according to an embodiment of the present invention is shown. As Figure 1 shown, the method includes the following steps:

[0027] Step S101: Determine the macro / micro type of the site.

[0028] In step S101, the public parameter data of the whole network can be extracted, and the macro / micro type of the site can be determined according to the extracted public parameter data. Among them, the macro / micro type can include macro stations and micro stations. Specifically, each macro station can cover a cellular area, and within each cellular area, there can also be micro stations, which can be femtocell base stations (Femto), relays (Relay), and picocells (Pico). Among them, Femto is usually a home base station.

[0029] Step S102: Calculate the first inflection point value of the traffic-carrying capacity of each frequency band.

[0030] For each frequency band, extract the cell self-busy-hour traffic of this frequency band in the underlying network within a preset period from the whole network, and arrange the cell self-busy-hour traffic in descending order; select the preset number of cell self-busy-hour traffic with the top ranking as the traffic to be calculated; calculate the average value of the traffic to be calculated, and take the average value as the first inflection point value of the traffic-carrying capacity of this frequency band. Among them, the preset period can be in days. The cell self-busy-hour traffic is one of the important bases for evaluating the site traffic at present. The cell self-busy-hour traffic mainly includes three major indicators: the total site traffic, the average PRB (physical resource block) utilization rate, and the maximum number of RRC (Radio Resource Control) connected users.

[0031] Taking the F frequency band as an example, extract the cell self-busy-hour traffic of the F frequency band in the underlying network within a preset period from the whole network. The cell self-busy-hour traffic can be in days. Arrange the cell self-busy-hour traffic in descending order, and select the cell self-busy-hour traffic within the top 10% interval with the top ranking as the traffic to be calculated. Take the average value of the traffic to be calculated as the first inflection point value of the traffic-carrying capacity of this frequency band. For the calculation of the first inflection point value, the following formula (1) can be used for calculation:

[0032]

[0033] Among them, g represents the first inflection point value; n represents the total number of traffic to be calculated; x i represents the value of the i-th traffic to be calculated.

[0034] Step S103: Calculate the traffic-carrying capacity of the entire sector after frequency coordination based on the carrier configuration data, service balance coefficient, and the first inflection point value.

[0035] To accurately determine the final frequency coordination plan, it is also necessary to calculate the traffic-carrying capacity of the entire sector after frequency coordination in accordance with the equivalent carrier principle, combining the carrier configuration after frequency coordination and the service balance coefficient. Among them, the carrier configuration data may include: the equivalent carrier coefficient corresponding to each carrier, the equivalent number of carriers in the D1 frequency band and the D2 frequency band within the sector, etc.

[0036] Specifically, the second inflection point value of the traffic-carrying capacity of the entire sector can be calculated based on the equivalent carrier coefficient corresponding to each carrier, the first inflection point value, and the traffic inflection point coefficient. For the calculation of the second inflection point value of the traffic-carrying capacity of the entire sector, the following formula (2) can be used for calculation:

[0037]

[0038] where G represents the second inflection point value; η represents the traffic inflection point coefficient; j represents the number of carriers within the sector; d j represents the equivalent carrier coefficient corresponding to each carrier (the equivalent carrier coefficient of the F frequency band is 1); g represents the first inflection point value.

[0039] After calculating the second inflection point value, the traffic-carrying capacity of the entire sector after frequency coordination can be calculated based on the service balance coefficient, the second inflection point value, the traffic inflection point coefficient, the equivalent number of carriers in the D1 frequency band and the D2 frequency band within the sector, and the first inflection point value. For the calculation of the traffic-carrying capacity of the entire sector after frequency coordination, the following formula (3) can be used for calculation:

[0040] P = ρ * [G - η * y * g] Formula (3)

[0041] where P represents the traffic-carrying capacity of the entire sector after frequency coordination; ρ represents the service balance coefficient; G represents the second inflection point value; η represents the traffic inflection point coefficient; y represents the equivalent number of carriers in the D1 frequency band and the D2 frequency band (i.e., D1 + D2) within the sector; g represents the first inflection point value.

[0042] Step S104: Determine whether the traffic-carrying capacity of the entire sector after frequency coordination is greater than or equal to the current traffic volume of the site sector; if so, execute Step S105; if not, execute Step S106.

[0043] Suppose that \(P\) represents the capacity of the entire sector to carry traffic after frequency coordination, and \(Q\) represents the current traffic volume of the site sector. If it is determined that the capacity of the entire sector to carry traffic after frequency coordination is greater than or equal to the current traffic volume of the site sector, that is, \(P\geq Q\), it means that the capacity of the entire sector to carry traffic after frequency coordination is sufficient to carry the current traffic volume of the site sector, then step S105 is executed for frequency withdrawal processing. If it is determined that the capacity of the entire sector to carry traffic after frequency coordination is less than the current traffic volume of the site sector, that is, \(P < Q\), it means that the capacity of the entire sector to carry traffic after frequency coordination is insufficient to carry the current traffic volume of the site sector, and the surrounding sectors need to be used to absorb traffic, then step S106 is executed.

[0044] Step S105, perform frequency withdrawal processing.

[0045] Step S106, according to the macro-micro type of the site, adopt the surrounding opposite-sector absorption method or the surrounding sampling point ratio estimation absorption capacity method to calculate the total value of the traffic absorbed by the surrounding sectors.

[0046] (1) If the macro-micro type of the site is a macro site, the surrounding opposite-sector absorption method is adopted to calculate the total value of the traffic absorbed by the surrounding sectors. Among them, using the surrounding opposite-sector absorption method to calculate the total value of the traffic absorbed by the surrounding sectors further includes: obtaining the current traffic volume of the surrounding sectors, calculating the capacity of the surrounding sectors to carry traffic after frequency coordination based on the current traffic volume of the surrounding sectors; calculating the traffic redundancy of the surrounding sectors after frequency coordination according to the capacity of the surrounding sectors to carry traffic after frequency coordination and the current traffic volume of the surrounding sectors; calculating the total value of the traffic absorbed by the surrounding sectors according to the absorption coefficient, traffic balance coefficient of the surrounding sectors and the traffic redundancy of the surrounding sectors after frequency coordination.

[0047] Specifically, according to on-site testing and simulation, the absorption coefficient of the surrounding sectors within a certain station spacing range can be obtained. The corresponding relationship between the station spacing and the absorption coefficient can be shown in Table 1. If the station spacing is less than 50m, the corresponding absorption coefficient is \(\mu\) 1 ; if the station spacing is less than 100m and greater than or equal to 50m, the corresponding absorption coefficient is \(\mu\) 2 ; if the station spacing is less than 150m and greater than or equal to 100m, the corresponding absorption coefficient is \(\mu\) 3 .

[0048] Station spacing Absorption coefficient Station spacing < 50m <![CDATA[μ 1 > 50m ≤ Station spacing < 100m <![CDATA[μ 2 > 100m ≤ Station spacing < 150m <![CDATA[μ 3 >

[0049] Table 1. Corresponding relationship between station spacing and absorption coefficient

[0050] For the calculation of the capacity of the surrounding sectors to carry traffic after frequency coordination, it can be calculated according to the current traffic volume of the surrounding sectors by using the existing frequency coordination calculation method, which will not be elaborated here.

[0051] For the calculation of the traffic redundancy after the frequency coordination of the surrounding sectors, the following formula (4) can be used for calculation:

[0052] S k = max[(P k - Q k ), 0] Formula (4)

[0053] Where k represents the number of the surrounding sectors (i.e., the surrounding sectors with mutual communication); S k represents the traffic redundancy after the frequency coordination of the surrounding sector numbered k; P k represents the traffic carrying capacity after the frequency coordination of the surrounding sector numbered k; Q k represents the current traffic of the surrounding sector numbered k. Formula (4) means that if (P k - Q k ) is greater than or equal to 0, then S k takes (P k - Q k ); if (P k - Q k ) is less than 0, then S k takes 0.

[0054] Assume that the total number of the surrounding sectors is k. For the calculation of the total absorbed traffic value of the surrounding sectors, the following formula (5) can be used for calculation:

[0055]

[0056] Where R represents the total absorbed traffic value of the surrounding sectors; ρ represents the traffic balance coefficient; S k represents the traffic redundancy after the frequency coordination of the surrounding sector numbered k; μ k represents the absorption coefficient of the surrounding sector numbered k.

[0057] (2) If the macro - micro type of the site is a micro - station, the total absorbed traffic volume of the surrounding sectors is calculated by the method of estimating the absorption capacity based on the proportion of surrounding sampling points. Specifically, the method of calculating the total absorbed traffic volume of the surrounding sectors by estimating the absorption capacity based on the proportion of surrounding sampling points further includes: obtaining the measurement reports of the surrounding sites, analyzing the measurement reports to determine the target sector where the target sampling point is located and the proportion of sampling points in the target sector; obtaining the current traffic volume of the target sector, and calculating the absorption traffic volume capacity of the target sector and the carried traffic volume capacity after frequency coordination of the target sector based on the current traffic volume of the target sector and the proportion of sampling points; calculating the traffic volume redundancy after frequency coordination of the target sector according to the carried traffic volume capacity after frequency coordination of the target sector and the current traffic volume of the target sector; selecting the smaller value between the absorption traffic volume capacity of the target sector and the traffic volume redundancy after frequency coordination of the target sector as the absorption traffic volume of the target sector; and statistically summing up the absorption traffic volumes of all target sectors to obtain the total absorbed traffic volume of the surrounding sectors.

[0058] Specifically, it is necessary to subscribe to the measurement reports (MR) of the surrounding sites absorbed by the micro - station, obtain the MR of the subscribed surrounding sites, and analyze and process the obtained MR to output the list of the target sectors where the target sampling points are located and the proportion of sampling points in the target sectors. In specific applications, the sampling points within 6 dB of the micro - station sector can be used as the target sampling points, and several cells with the highest proportion of sampling points can be selected, such as the first 5 cells.

[0059] For the calculation of the absorption traffic volume capacity of the target sector, the following formula (6) can be used for calculation:

[0060] W l =Q l *ε l Formula (6)

[0061] Where l represents the number of the target sector; W l represents the absorption traffic volume capacity of the target sector numbered l; Q l represents the current traffic volume of the target sector numbered l; ε l represents the proportion of sampling points in the target sector numbered l.

[0062] For the calculation of the carried traffic volume capacity after frequency coordination of the target sector, it can be calculated according to the current traffic volume of the target sector by using the existing frequency coordination calculation method, which will not be elaborated here.

[0063] For the calculation of the traffic volume redundancy after frequency coordination of the target sector, the following formula (7) can be used for calculation:

[0064] S l =max[(P l -Q l), 0] Formula (7)

[0065] Wherein, l represents the number of the target sector; S l represents the traffic redundancy after frequency coordination of the target sector numbered l; P l represents the traffic carrying capacity after frequency coordination of the target sector numbered l; Q l represents the current traffic volume of the target sector numbered l. Formula (7) means that if (P l -Q l ) is greater than or equal to 0, then S l takes (P l -Q l ); if (P l -Q l ) is less than 0, then S l takes 0.

[0066] After calculating the traffic redundancy after frequency coordination of the target sector, the smaller value of the traffic absorption capacity of the target sector and the traffic redundancy after frequency coordination of the target sector can be selected as the traffic absorption volume of the target sector, and then the total traffic absorption volume of the surrounding sectors can be obtained by counting the sum of the traffic absorption volumes of all target sectors. Assuming that the total number of target sectors is l, for the calculation of the total traffic absorption volume of the surrounding sectors, the following formula (8) can be used for calculation:

[0067]

[0068] Wherein, E represents the total traffic absorption volume of the surrounding sectors; W l represents the traffic absorption capacity of the target sector numbered l; S l represents the traffic redundancy after frequency coordination of the target sector numbered l.

[0069] Step S107, determine the frequency coordination scheme according to the traffic carrying capacity of the entire sector after frequency coordination, the current traffic volume of the site sector, and the total traffic absorption volume of the surrounding sectors.

[0070] Specifically, judge whether the sum of the traffic carrying capacity of the entire sector after frequency coordination and the total traffic absorption volume of the surrounding sectors is greater than or equal to the current traffic volume of the site sector; if so, it means that the current traffic volume of the site sector can be carried after absorbing the traffic of the surrounding sectors, and then frequency reduction processing is performed; if not, it means that the current traffic volume of the site sector still cannot be carried after absorbing the traffic of the surrounding sectors, and then capacity supplement processing is required, and frequency reduction processing is performed after capacity supplement.

[0071] According to the network frequency coordination method based on macro and micro sector traffic absorption provided by this embodiment, without affecting the quality of the existing 4G network, it can determine the traffic absorption of the same sector and surrounding sectors of macro and micro stations in combination with the bearing capacity of macro and micro stations in the existing network. For macro stations, the total traffic absorption of surrounding sectors is calculated by the method of absorbing traffic from surrounding opposite sectors. For micro stations, the total traffic absorption of surrounding sectors is calculated by the method of estimating the absorption capacity based on the proportion of surrounding sampling points. According to the absorption characteristics of macro and micro sectors, this solution formulates different absorption methods, scientifically evaluates whether the 4G site meets the conditions for direct frequency withdrawal, can not only ensure the stability of the 4G network, but also quickly promote the implementation of 4G / 5G frequency coordination, rationally reuse the redundant resources in the existing network, realize scientific 4G / 5G frequency coordination, and make up for the defects of the existing 4G / 5G frequency coordination solutions.
