Description

A method and device for optimizing network resources

technical field

Embodiments of the present invention relate to the technical field of mobile communications, and in particular, to a method and apparatus for optimizing network resources.

Background technique

With the continuous construction of the LTE (Long Term Evolution) network, the coverage of the LTE network will continue to improve, and the advantages of service experience and the promotion of the market sector will attract a large number of users from the existing GSM (Global System for Mobile Communication) ) network to LTE network. The high-speed Internet experience brought by the LTE network standard is more attractive to users than the GSM network. The VoLTE (Voice over LTE) service uses a higher bandwidth to carry the voice service, and the voice quality is higher than that of the GSM network. Will be gradually absorbed by LTE networks. The optimization and planning of the existing wireless resources of the GSM network, such as frequencies, parameters, and hardware, are facing a new situation. In the early stage, a large amount of GSM equipment was invested to provide stable network support for various scenarios with high traffic and high-density users. After the service drops sharply, a large number of ultra-idle cells will inevitably appear, the equipment utilization efficiency will be greatly reduced, and the phenomenon of idle resources and ineffective energy consumption will appear in a large area.

In the prior art, the GSM wireless network resource planning and optimization evaluation are mainly calculated by calculating the total service wireless utilization rate. However, when calculating the total service wireless utilization rate, the capacity of each channel of cells with different configurations is set to the same value, which is 1ERL*. 0.75. Figure 1 is a schematic diagram of the relationship between cell configuration and channel capacity in the prior art. As shown in Figure 1, the abscissa corresponds to the cell resource configuration, and the ordinate corresponds to the capacity of each channel. It can be seen that the lower the cell configuration, the more The smaller the capacity; the higher the configuration, the greater the capacity per channel. Therefore, the wireless utilization index cannot be applied to all configured cells, and planning and optimizing GSM wireless network resources through wireless utilization will result in inaccurate planning and optimization results. At the same time, in the prior art, the wireless resource adjustment is based on the calculated wireless utilization rate, and the adjustment plan is manually given. There is no fixed standard, and the subjectivity is strong. Different staff members give inconsistent resource adjustment plans, which further causes wireless network resources. Inaccuracies of tuning and optimization results. And with the continuous decline of the GSM network traffic, the workload of wireless resource adjustment will continue to increase, and the efficiency of manual adjustment is relatively low.

Therefore, how to propose a method that can improve the accuracy of wireless network resource optimization has become an urgent problem to be solved.

Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

FIG. 2 is a schematic flowchart of a method for optimizing network resources in an embodiment of the present invention. As shown in FIG. 2 , the method for optimizing network resources provided by an embodiment of the present invention includes:

S1. Acquire the radio resource configuration of the wireless network cell and the traffic volume within a preset time, wherein the traffic volume includes the voice service traffic volume and the data service traffic volume, and the radio resource configuration of the wireless network cell includes a definition number of channels;

Specifically, the radio resource configuration of the wireless network cell and the traffic volume of the wireless network cell within a preset time period are acquired, specifically including the voice service traffic volume and the data service traffic volume. The radio resource configuration of the wireless network cell includes defining the number of channels, that is, the number of channels normally set in the cell, which may specifically be the number of TCHs (TrafficChannel, traffic channels) normally set in the cell. The radio resource configuration may also include the type and corresponding quantity of channels, such as BCCH (Broadcast Control Channel, broadcast control channel) and its quantity, SDCCH (Stand-Alone Dedicated Control Channel, independent dedicated control channel) and its quantity, of course, can also include The wireless resource configuration of other wireless network cells is not specifically limited in this embodiment of the present invention. The preset time may be set according to actual needs, and the embodiment of the present invention counts the voice traffic and data traffic in the wireless network cell within one hour.

S2. Acquire the number of required channels of the wireless network cell according to a preset rule. If it is determined that the number of required channels is greater than the defined number of channels, expand and optimize the wireless network cell. If the number is less than the defined number of channels, the capacity reduction and optimization of the wireless network cell is performed;

The preset rule includes: querying the Irish B table for the first channel number corresponding to the preset call loss rate according to the voice service traffic volume, and comparing the first channel number with the voice service traffic volume. The difference is taken as the traffic volume of the first data service to be carried;

Taking the difference between the traffic volume of the data service and the traffic volume of the first data service as the traffic volume of the second data service to be carried by a channel that needs to be provided separately, according to the traffic volume of the second data service, in the Ireland Query the second channel number corresponding to the preset call loss rate in table B;

Dividing the sum of the first number of channels and the second number of channels by a preset redundancy threshold is used as the number of required channels.

Specifically, after acquiring the voice service traffic volume and data service traffic volume of the wireless network cell within the preset time, according to the acquired voice service traffic volume, it is possible to query the Irish B table corresponding to the preset call loss rate. The first channel number. The preset call loss rate may be set as required, which is not specifically limited in this embodiment of the present invention. Usually, the number of the first channels queried is greater than the acquired voice traffic volume of the cell, which means that if all the channels corresponding to the first number of channels are used to carry voice services, there will be some redundant channels. The obtained voice service traffic is taken as the first data service traffic that is also carried. Then, the obtained data service traffic of the wireless network cell is subtracted from the first data service traffic, that is, the second data service traffic that needs to be provided separately for the channel bearer is obtained. According to the traffic volume of the second data service, query the second channel number corresponding to the preset call loss rate in the Irish B table, calculate the sum of the first channel number and the second channel number, and then divide the obtained result by the preset redundancy The threshold is used as the number of required channels, wherein the number of required channels refers to the number of THC channels required by the wireless network cell. The specific value of the preset redundancy threshold may be set according to the actual use situation, which is not specifically limited in this embodiment of the present invention. Compare the calculated number of demand channels with the pre-acquired number of defined channels of the wireless network cell. If the number of demand channels is greater than the number of defined channels, it indicates that the channel resource allocation in the wireless network cell is insufficient, and the wireless network cell is optimized for capacity expansion; If the number of required channels is greater than the number of defined channels, it means that the channel resources in the wireless network cell will be wasted, and the capacity reduction and optimization of the wireless network cell is performed. The capacity expansion optimization and the capacity reduction optimization refer to changing the carrier frequency capacity in the wireless network cell by changing the number of channels in the wireless network cell.

Fig. 3 is a distribution diagram of the channels occupied by voice traffic and data traffic in an embodiment of the present invention. As shown in Fig. 3, the abscissa represents time, and the ordinate represents the number of occupied channels. The number of channels occupied by the voice service traffic and the data service traffic within a time, and the corresponding line graphs are drawn respectively, as shown in Figure 3. In the process of implementing the embodiments of the present invention, it is found that if data services are not considered, the channels corresponding to the traffic of voice services are usually redundant and can be used to carry data services, while the remaining data services need to be separated separately. channel resource bearer. In the embodiment of the present invention, a straight line parallel to the abscissa axis is drawn at the peak of the voice traffic, that is, the corresponding TCH channel is 12. As shown in FIG. 3, the straight line divides the data traffic into two parts, and the lower part of the straight line corresponds to The data service traffic can be carried through the channel of the voice service traffic, that is, in order to take into account the first data service traffic carried, the data service traffic above the line needs to be carried by a separate new channel, that is is the traffic volume of the second data service. It can be seen that in the embodiment of the present invention, the data service traffic is divided into the first data service traffic that takes into account the bearer and the second data service traffic that needs to be carried by a separate channel, where the first data service traffic can be The channel carrying the voice service is carried, and the second data service traffic needs to be provided with new channel resources to carry.

For example, it is assumed that the traffic volume of the voice service in the wireless network cell is C, and the traffic volume of the data service is P. Querying from Irish B table that the traffic volume of the voice service is C and the number of TCH channels corresponding to the preset call loss rate is T1, then the traffic volume of the first data service carried is P1=T1-C, and the first data service traffic volume carried by the channel needs to be provided separately. Two data service traffic P2=P-P1. The number of TCH channels corresponding to the traffic volume P2 of the second data service and the preset call loss rate is T2. Assuming that the preset redundancy threshold is a, the number of required channels is T=(T1+T2)/ a. Assuming that the defined number of channels of the wireless network cell is t, compare the sizes of T and t. If it is judged that T>t, the wireless network cell will be expanded and optimized; if it is judged that T<t, the wireless network cell will be optimized. Capacity reduction optimization. The specific methods for performing capacity expansion optimization and capacity reduction optimization may be set according to actual conditions, which are not specifically limited in the embodiment of the present invention.

The network resource optimization method in the embodiment of the present invention is described in detail below, so as to better understand the specific solution of the embodiment of the present invention.

Table 2 is the network resource evaluation table of the wireless network cell in the embodiment of the present invention. As shown in Table 2, the daily busy-hour traffic of the cell in the table corresponds to the acquired voice traffic in the cell, which is equivalent to The data traffic corresponds to the obtained data service traffic. The specific process of network resource optimization is as follows:

According to the traffic volume of the voice service, query the corresponding first channel number from the Irish B table. For example, the traffic volume of the voice service in the wireless network cell D22R023 is the daily busy time traffic volume of the cell in Table 2, which is 8.02. Ireland B inquires that the number of TCH channels corresponding to the corrected capacity of 8.571 is 20, which is the number of TCH channels corresponding to the voice traffic of the D22R023 cell in the embodiment of the present invention, that is, the first number of channels T1=20. Then the traffic volume of the first data service carried by the D22R023 cell is P1=20-8.02≈12. It can be seen from Table 2 that the data traffic volume of the D22R023 cell is the equivalent data traffic volume P=7.61, then a separate The second data service traffic P2=7.61-12=-5 borne by the channel is provided, and the result is a negative value, indicating that the redundant channel can carry all the data service traffic, and no additional channels are required. In the embodiment of the present invention, the preset redundancy threshold is set to 85%, and there is no corresponding second channel number in Table 1 through P2=-5, that is, it can be considered that the second channel number T2=0 is queried, then the D22R023 cell has no corresponding second channel number. The number of required channels is T=(T1+T2)/85%=20/85%=23.52941. It can be seen that the number of channels defined in the D22R023 cell in Table 2 is 59>23.52941. Therefore, the D22R023 cell can be optimized for capacity reduction. Specifically, the D22R023 cell can be reduced by 35 TCH channels, that is, by 4 carrier frequencies. The same method is used to calculate the number of required channels in G228091 and G02H063. After comparison, it is found that the difference between the number of required channels and the number of defined channels in G228091 and G02H063 is small, both less than 8, because one carrier frequency corresponds to 8 channels. If the difference between the number of required channels and the number of defined channels is small, the G228091 cell and the G02H063 cell may not be optimized for capacity reduction or expansion.

Table 2: Network resource evaluation form for wireless network cells

Table 3 is the network resource evaluation table of the D229213 cell in the embodiment of the present invention. Using the method in the above-mentioned embodiment, it is calculated that the number of required channels in the D229213 cell is 123.5294, and the number of defined channels in the D229213 cell is 71. Therefore, it is necessary to The D229213 cell can be expanded, specifically, the number of channels can be expanded by 53, that is, the number of carrier frequencies can be expanded.

In addition, it can be seen from Table 3 that the half-rate traffic volume of the D229213 cell is high. In practical applications, in order to ensure the quality of service, the number of channels required to enable full-rate traffic in the D229213 cell can also be calculated. Capacity expansion, specific calculation method is not specifically limited in the embodiment of the present invention.

Table 3: Network resource evaluation form of D229213 cell

The network resource optimization method provided by the embodiment of the present invention can reasonably calculate the number of required channels of a wireless network cell, compare the calculated number of required channels with the number of defined channels of the wireless network cell, and further calculate the number of required channels of the wireless network cell. The network resources are optimized for capacity expansion or capacity reduction, so that the optimization result of the wireless network cell is more accurate and reasonable.

On the basis of the foregoing embodiment, the performing capacity reduction and optimization on the wireless network cell includes: the capacity of the wireless network cell after the capacity reduction and optimization is greater than or equal to two carrier frequencies.

Specifically, in order to ensure the service quality of the wireless network cell, when reducing the capacity of the wireless network cell that needs to be optimized for capacity reduction, the minimum capacity is reduced to two carrier frequencies.

On the basis of the above-mentioned embodiment, the method further includes: according to the wireless resource configuration, if it is determined that there are multiple wireless network cells with two carrier frequencies in the same base station, placing the multiple wireless network cells with two carrier frequencies on the same base station. Network cells are combined and optimized;

The combined and optimized wireless network cell has the same signal coverage as the multiple two-carrier frequency wireless network cells.

Specifically, because the resource configuration of the two carrier frequencies can carry relatively little traffic, if there are too many wireless network cells of the two carrier frequencies, resources will be wasted. This embodiment of the present invention determines whether there are multiple wireless network cells with two carrier frequencies in the same base station according to the acquired wireless resource configuration of multiple wireless network cells, and if so, combines multiple wireless network cells with two carrier frequencies. optimization, so that the combined and optimized wireless network cells have the same signal coverage as the original multiple wireless network cells with two carrier frequencies. The specific method for cell combination optimization may be to expand the capacity of one of the cells by means of power division combination, and disable the other cells, so that the signal coverage of the expanded cell is the same as that of the original two-carrier wireless network cells. The signal coverage is the same.

For example, the experiment is carried out with the GX West Ocean base station. The traffic volume of the G2 cell and the G3 cell of the base station is low, and both are two carrier frequency cells. In the embodiment of the present invention, the G3 cell of the GX West Ocean base station is reserved and the capacity is expanded to 4 carrier frequencies, and the G2 cell of the GX West Ocean base station is stopped. The signal coverage of the cells is the same. FIG. 4 is a comparison diagram of the traffic volume after the GX West Ocean base station performs cell merging in the embodiment of the present invention. As shown in FIG. 4 , the abscissa axis represents time, and the ordinate axis represents the traffic volume. Traffic curve graph, compared with the same time period, the traffic volume after the cell combination is higher than the traffic volume before the combination. The highest peak value is 3.99erl, which is higher than the carrying capacity of the two-carrier cell. Fig. 5 is a schematic diagram of TA distribution of G2 cells before GX West Ocean base station performs cell merging in an embodiment of the present invention, Fig. 6 is a schematic diagram of TA distribution of G3 cells before GX West Ocean base station performs cell merging in an embodiment of the present invention, and Fig. 7 is the In the embodiment of the invention, a schematic diagram of the TA distribution of the G3 cell after cell merging is performed by the GX West Ocean base station. Combining with Figure 5, Figure 6 and Figure 7, it can be seen that after the cells are merged, the users of the original G2 cell and the G3 cell are concentrated in the merged cell. In the area of G3 cell.

The network resource optimization method provided by the embodiment of the present invention combines multiple wireless network cells with two carrier frequencies belonging to the same base station by loading two power divisions, thereby reducing the number of wireless network cells with two carrier frequencies and avoiding The waste of network resources makes the resource optimization of wireless network cells more reasonable and accurate.

On the basis of the foregoing embodiment, the method further includes: acquiring, according to the radio resource configuration, a first radio network cell and a second radio network cell that meet preset conditions in the same base station controller, and using a carrier pool system to The first wireless network cell and the second wireless network cell are combined and optimized, and the combined and optimized wireless network cell is the same as the sum of the signal coverage of the first wireless network cell and the second wireless network cell;

The preset condition includes: the coincidence degree of the traffic peak time of the first wireless network cell and the traffic valley time of the second wireless network cell is greater than a preset threshold.

Specifically, since the peak time and the valley time of the traffic of each wireless network cell will be different, a tidal effect will occur. For example, a commercial office building generates a large amount of traffic during working hours, while the traffic is greatly reduced during non-working hours. On the contrary, in residential buildings, the number of users increases during non-working hours, and the traffic volume during working hours is lower. In the embodiment of the present invention, the first wireless network cell and the second wireless network cell of the same base station controller, that is, a BSC (Base Station Controller), are obtained according to the wireless resource configuration of each wireless network cell obtained by statistics, and the first wireless network cell is determined. Whether the coincidence degree between the traffic peak time of the cell and the traffic valley time of the second wireless network cell is greater than a preset threshold. That is, it is judged whether the coincidence degree of the time period with more traffic in the first wireless network cell and the time period with less traffic in the second wireless network cell is greater than the preset threshold, and if it is greater than the first wireless network cell The carrier pool system is used to perform combination optimization with the second wireless network cell, so that the signal coverage of the combined and optimized wireless network cell is the same as the sum of the signal coverage of the first wireless network cell and the second wireless network cell before the combination. The number of the first wireless network cell and the second wireless network cell may be one or more, which is not specifically limited in this embodiment of the present invention. The carrier pool system is also known as the carrier frequency pool system. This system can provide radio frequency loading for idle base station carrier frequencies. The integrated network management center assigns signal links on the network, and schedules carrier frequency resources to areas with high communication needs in real time or regularly to absorb the Regional traffic. The carrier pool system can solve the cell group with the characteristics of tidal effect, and effectively improve the efficiency of carrier use through the superposition of traffic.

For example, according to the wireless resource configuration, it is found that the signal coverage of wireless network cell A is mainly office buildings, and the peak time of its traffic is concentrated from 10:00 am to 5:00 pm, and other times correspond to the valley time of traffic. The signal coverage of wireless network cell B is mainly residential buildings. The peak time of its traffic is concentrated from 6:00 pm to 12:00 pm, and other times correspond to the valley time of traffic volume. It can be seen that at 10:00 in the morning During the period from 1:00 pm to 5:00 pm, the network resources of wireless network cell B are mainly in idle state, while the network resources of wireless network cell A are in a state. Assuming that the coincidence degree is my preset threshold of 4 hours, it can be seen that the wireless network The traffic peak time of cell A and the traffic valley time of wireless network cell B, that is, the wireless network cell A and the wireless network cell B are combined using the carrier pool system, that is, the wireless network cell A and the wireless network cell are merged using the carrier pool system. B performs traffic stacking to improve carrier usage efficiency.

In the network resource optimization method provided by the embodiment of the present invention, through the carrier pool system, multiple wireless network cells with tidal effect characteristics within the control range of the same base station controller are combined, so that the network resources of each wireless network cell can be fully obtained. Utilization improves the utilization rate of network resources and makes the resource allocation of wireless network cells more reasonable.

On the basis of the above embodiment, the radio resource configuration further includes the number of broadcast control channels, and accordingly, the method further includes: increasing the frequency resource ratio of the broadcast control channel.

Specifically, as the traffic volume decreases, the carrier of the TCH channel decreases continuously, but the carrier of the broadcast control channel, that is, the BCCH will not decrease.

FIG. 8 is a schematic structural diagram of an apparatus for optimizing network resources in an embodiment of the present invention. As shown in FIG. 8 , the apparatus for optimizing wireless network resources provided by an embodiment of the present invention includes: an information acquisition unit 801 and a resource optimization unit 802, wherein:

The information obtaining unit 801 is configured to obtain the wireless resource configuration of the wireless network cell and the traffic volume within a preset time, wherein the traffic volume includes the voice service traffic volume and the data service traffic volume. The resource configuration includes defining the number of channels; the resource optimization unit 802 is configured to obtain the number of required channels of the wireless network cell according to a preset rule, and if it is determined that the number of required channels is greater than the defined number of channels, the wireless network cell Carry out capacity expansion optimization, and if it is determined that the number of demanded channels is less than the defined number of channels, reduce and optimize the capacity of the wireless network cell;

The preset rule includes: querying the Irish B table for the first channel number corresponding to the preset call loss rate according to the voice service traffic volume, and comparing the first channel number with the voice service traffic volume. The difference is taken as the traffic volume of the first data service to be carried;

Taking the difference between the traffic volume of the data service and the traffic volume of the first data service as the traffic volume of the second data service to be carried by a channel that needs to be provided separately, according to the traffic volume of the second data service, in the Ireland Query the second channel number corresponding to the preset call loss rate in table B;

Dividing the sum of the first number of channels and the second number of channels by a preset redundancy threshold is used as the number of required channels.

Specifically, the information obtaining unit 801 obtains the wireless resource configuration of the wireless network cell, and the traffic volume of the wireless network cell within a preset time, specifically including the voice service traffic volume and the data service traffic volume. The radio resource configuration of the wireless network cell includes defining the number of channels, that is, the number of channels normally set in the cell, which may specifically be the number of TCH (Traffic Channel, traffic channel) channels normally set in the cell. The resource optimization unit 802 can query the Irish B table to find the first channel number corresponding to the preset call loss rate according to the voice service traffic volume acquired by the information acquisition unit 801 . Then, the obtained data service traffic of the wireless network cell is subtracted from the first data service traffic, that is, the second data service traffic that needs to be provided separately for the channel bearer is obtained. According to the traffic volume of the second data service, query the second channel number corresponding to the preset call loss rate in the Irish B table, calculate the sum of the first channel number and the second channel number, and then divide the obtained result by the preset redundancy The threshold is used as the number of required channels, wherein the number of required channels refers to the number of THC channels required by the wireless network cell. Compare the calculated number of demand channels with the pre-acquired number of defined channels of the wireless network cell. If the number of demand channels is greater than the number of defined channels, it indicates that the channel resource allocation in the wireless network cell is insufficient, and the wireless network cell is optimized for capacity expansion; If the number of required channels is greater than the number of defined channels, it means that the channel resources in the wireless network cell will be wasted, and the capacity reduction and optimization of the wireless network cell is performed.

The radio resource configuration, the preset call loss rate, the preset redundancy threshold, and the specific method for querying the Irish B table are the same as those in the above-mentioned embodiment, and will not be repeated here.

The network resource optimization device provided by the embodiment of the present invention can reasonably calculate the number of required channels of a wireless network cell, compare the calculated number of required channels with the number of defined channels of the wireless network cell, and further calculate the number of required channels of the wireless network cell. The network resources are optimized for capacity expansion or capacity reduction, so that the optimization result of the wireless network cell is more accurate and reasonable.

On the basis of the foregoing embodiment, the performing capacity reduction and optimization on the wireless network cell includes: the capacity of the wireless network cell after the capacity reduction and optimization is greater than or equal to two carrier frequencies.

Specifically, in order to ensure the service quality of the wireless network cell, when reducing the capacity of the wireless network cell that needs to be optimized for capacity reduction, the minimum capacity is reduced to two carrier frequencies.

On the basis of the above embodiment, the resource optimization unit is further configured to: according to the wireless resource configuration, if it is determined that there are multiple wireless network cells with two carrier frequencies in the same base station, the multiple two carrier frequencies The wireless network cells with high frequency are combined and optimized;

The combined and optimized wireless network cell has the same signal coverage as the multiple two-carrier frequency wireless network cells.

Specifically, because the resource configuration of the two carrier frequencies can carry relatively little traffic, if there are too many wireless network cells of the two carrier frequencies, resources will be wasted. The resource optimization unit in the embodiment of the present invention determines whether there are multiple wireless network cells with two carrier frequencies in the same base station according to the acquired wireless resource configurations of multiple wireless network cells, and if there are multiple wireless network cells with two carrier frequencies The wireless network cells are combined and optimized, so that the combined and optimized wireless network cells have the same signal coverage as the original multiple wireless network cells with two carrier frequencies. A specific method for cell combination optimization may be to expand the capacity of one of the cells by means of power division combination, so that the signal coverage of the cell is the same as the signal coverage of the original two-carrier wireless network cells.

The preset condition includes: the coincidence degree of the traffic peak time of the first wireless network cell and the traffic valley time of the second wireless network cell is greater than a preset threshold.

Specifically, since the peak time and the valley time of the traffic of each wireless network cell will be different, a tidal effect will occur. For example, a commercial office building generates a large amount of traffic during working hours, while the traffic is greatly reduced during non-working hours. On the contrary, in residential buildings, the number of users increases during non-working hours, and the traffic volume during working hours is lower. In the embodiment of the present invention, the resource optimization unit obtains the first wireless network cell and the second wireless network cell of the same base station controller, namely the BSC (Base Station Controller), according to the wireless resource configuration of each wireless network cell obtained by statistics, and determines the first wireless network cell and the second wireless network cell of the same base station controller (BSC). Whether the coincidence degree of the traffic peak time of one wireless network cell and the traffic valley time of the second wireless network cell is greater than a preset threshold. That is, it is judged whether the coincidence degree of the time period with more traffic in the first wireless network cell and the time period with less traffic in the second wireless network cell is greater than the preset threshold, and if it is greater than the first wireless network cell The carrier pool system is used to perform combination optimization with the second wireless network cell, so that the signal coverage of the combined and optimized wireless network cell is the same as the sum of the signal coverage of the first wireless network cell and the second wireless network cell before the combination. The number of the first wireless network cell and the second wireless network cell may be one or more, which is not specifically limited in this embodiment of the present invention. The carrier pool system is also known as the carrier frequency pool system. This system can provide radio frequency loading for idle base station carrier frequencies. The integrated network management center assigns signal links on the network, and schedules carrier frequency resources to areas with high communication needs in real time or regularly to absorb the Regional traffic. The carrier pool system can solve the cell group with the characteristics of tidal effect, and effectively improve the efficiency of carrier use through the superposition of traffic.

The network resource optimization device provided by the embodiment of the present invention combines multiple wireless network cells with tidal effect characteristics of the same base station controller through the carrier pool system, so that the network resources of each wireless network cell can be fully utilized, and the improvement of The utilization rate of network resources is improved, and the resource allocation of wireless network cells is more reasonable.

On the basis of the above embodiment, the radio resource configuration further includes the number of broadcast control channels, and accordingly the resource optimization unit is further configured to increase the frequency resource ratio of the broadcast control channel.

Specifically, as the traffic volume decreases, the carrier of the TCH channel decreases continuously, but the carrier of the broadcast control channel, that is, the BCCH will not decrease. In the embodiment of the present invention, the number of channels of the BCCH is obtained when the wireless resource configuration of the wireless network cell is obtained, and the resource optimization unit adjusts the frequency division rules of the BCCH and the TCH. Increase the frequency ratio of BCCH to reduce interference in the system. Specifically, the ratio of BCCH and TCH frequency points can be gradually adjusted to 1:2, 1:1, and 1.5:1 to provide more resources for BCCH frequency optimization.
