Description
Technical Field
The present invention relates to the field of network capacity configuration technologies, and in particular, to a method and an apparatus for configuring a mobile communication network capacity for a multi-layer network.
Background
The current mobile communication network capacity configuration method is to separately and independently calculate each layer of network carrier, for example, for a double-layer network base station, the 4G TDD carrier determines the capacity expansion requirement according to the own load, and the 5G TDD carrier also separately determines the capacity expansion requirement according to the own requirement, and the two calculation processes are mutually independent.
However, the multi-layer network base station can realize dynamic scheduling bearing of the service among different layer carriers by introducing load balancing and other technologies, so that the load degree of each layer is relatively uniform. Thus, the capacity of the multi-layer network base station is already an integral one, and we need to perform unified accounting. And the load unbalance between different layers in the same base station is avoided. For example, a base station of a two-layer network has a carrier of 4G TDD system and a carrier of 4G FDD system, if the base station is independently calculated and not from the whole, the utilization rate of the carrier of FDD is possibly too high (for example, more than 50%), and the capacity expansion requirement is generated, and the carrier of TDD is still in a light load state (the utilization rate is too low).
The capacity index of the current technical scheme is designed only for a single-layer wireless network (base station of a single technology system), for example, for a base station of a 4G network single-layer TDD system, the index of the current technical scheme is mostly the index suitable for single technology evaluation, such as the number of users and the channel utilization rate. The real wireless mobile communication network has been built for many years, and a multi-layer network structure is formed on the same physical site, which not only comprises a 4G TDD system, but also can comprise 4G FDD,5G TDD, 5G FDD and other systems. A single technical evaluation index cannot adapt to the current situation of multiple technical systems. Therefore, it is necessary to establish an evaluation index compatible with different technical systems for accounting the overall load of the base station.
Thus, the disadvantages of the prior art can be summarized:
1. The existing capacity configuration method is designed for a single-layer network, and cannot meet the evaluation requirement of a multi-layer network base station.
Because the index design aims at a single-layer base station, planners cannot perform balance judgment on other capacity resources in the same station, for example, one carrier wave of a double-layer network is excessively high in load and the other carrier wave is excessively low in load, and the final result is that errors occur in evaluation, and the errors expand the capacity of high-load carrier waves, so that resource waste is caused.
Because of a certain technology which is often aimed at in the existing capacity allocation index design, multiple standards, such as 4G TDD, 4G FDD, 5G TDD and 5G FDD, are difficult to be considered at the same time. For a multi-layer network base station, because each layer of network has own indexes, indexes to be analyzed by the base station are complex, indexes of each layer cannot be normalized, and thus the load condition of the whole base station is difficult to evaluate overall.
2. The existing capacity allocation method cannot provide accurate capacity expansion suggestions.
The problem of high load caused by interference factors cannot be eliminated, capacity expansion processing is still adopted, so that resource waste is caused, and meanwhile, interference elimination processing is delayed.
Therefore, how to avoid the problem that the existing capacity allocation method is designed for a single-layer network, cannot meet the evaluation requirement of a multi-layer network base station, and cannot exclude the influence of interference factors to perform blind capacity expansion to cause resource waste is still a problem to be solved by the technicians in the field.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of 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, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without any inventive effort, are intended to be within the scope of the invention.
The existing capacity allocation method generally has the problems that the existing capacity allocation method cannot meet the evaluation requirement of a multi-layer network base station aiming at single-layer network design and cannot exclude the influence of interference factors to carry out blind capacity expansion so as to cause resource waste. In this regard, the embodiment of the invention provides a mobile communication network capacity configuration method facing to a multi-layer network. Fig. 1 is a flow chart of a mobile communication network capacity configuration method for a multi-layer network according to an embodiment of the present invention, as shown in fig. 1, the method includes:
step 110, determining whether the full capacity resource utilization of the multi-layer network base station exceeds a preset upper threshold.
Specifically, it is first determined whether the full capacity resource utilization rate of the multi-layer network base station exceeds a standard, where the resource utilization rate is the load of the base station, and in general, the load is too high, and when the load is not high due to interference, the capacity expansion of the base station is required. Therefore, firstly, whether the resource utilization rate is standard or not is judged, if the resource utilization rate is not out of standard, no processing is needed, capacity expansion is not needed, and interference elimination is not needed. It should be noted that, the preset upper threshold is adjusted according to the actual application scenario, and the range of the preset upper threshold is typically between 50% and 70%.
And 120, if the full capacity resource utilization exceeds the preset upper limit threshold, determining whether the actual flow of the multi-layer network base station exceeds a preset calibration value.
Specifically, under the condition that the full capacity resource utilization rate of the multi-layer network base station is judged to be out of standard, whether the actual flow of the whole multi-layer network base station is out of standard is judged, if the actual flow is out of standard, the high load is caused by interference instead of insufficient capacity of the base station, capacity expansion processing is not needed, if the actual flow is out of standard, it can be determined that the high load of the base station can eliminate interference factor, but the capacity resource of the base station is insufficient, and corresponding capacity expansion processing is needed.
The method provided by the embodiment of the invention determines whether the full capacity resource utilization rate of the multi-layer network base station exceeds a preset upper limit threshold; if the full capacity resource utilization rate exceeds the preset upper limit threshold, determining whether the actual flow of the multi-layer network base station exceeds a preset calibration value; and if the actual flow exceeds the preset calibration value, performing capacity expansion processing on the multi-layer network base station. Therefore, the method and the system are suitable for multi-layer network base stations containing various technical systems by considering the resource utilization rate and the actual flow of the whole station full capacity, fully consider the service synergistic effect among the layers of networks in the base stations, ensure that the service is reasonably distributed among the layers, avoid the problem of mistaken expansion caused by unbalanced load among the layers of independent calculation, and simultaneously eliminate the situation that the base stations have high load caused by interference, thereby avoiding mistaken expansion. Therefore, the method provided by the embodiment of the invention realizes the method for providing accurate capacity expansion for the multi-layer network base station of various technical systems, and can also eliminate the problem of interference as redundant capacity expansion caused by insufficient capacity of the base station.
Based on the foregoing embodiment, in the method, the performing capacity expansion processing on the multi-layer network base station specifically includes:
and adding a new network layer to the multi-layer network base station for capacity expansion, calculating the full-capacity resource utilization rate of the expanded multi-layer network base station, and adding one new network layer to complete capacity expansion if the full-capacity resource utilization rate of the expanded multi-layer network base station does not exceed the preset upper limit threshold.
Specifically, after the capacity expansion processing is determined, a new network layer is selected to be added into the original multi-layer network base station for capacity expansion. Here, the carrier configuration bandwidth of the new network layer for capacity expansion is usually 20M, 40M, 60M, 80M or 100M, and after it is determined that capacity expansion is required, the carrier configuration bandwidth of the new network layer to be added is preferably the lowest level bandwidth, that is, 20M in the above example, and the frequency band of the new network layer for capacity expansion must be distinguished from the frequency band of each layer network of the original multi-layer network base station, for example, the frequency band of each layer network of the original multi-layer network base station is 900MHz to 1800MHz, and the frequency band of the new network layer for capacity expansion is 1900MHz or 2600 MHz. And after adding a new network layer to expand the capacity of the multi-layer network base station, calculating the full-capacity resource utilization rate of the expanded multi-layer network base station, and if the full-capacity resource utilization rate of the expanded multi-layer network base station does not exceed the preset upper limit threshold, completing the capacity expansion by taking one new network layer added at present as a final capacity expansion strategy.
Based on any of the above embodiments, the method further includes:
If the capacity-expanded full-capacity resource utilization rate of the multi-layer network base station still exceeds the preset upper limit threshold, repeating the following steps until the full-capacity resource utilization rate of the multi-layer network base station does not exceed the preset upper limit threshold: adding the new network layer to expand the capacity of the multi-layer network base station, calculating the full-capacity resource utilization rate of the multi-layer network base station after re-expansion, and judging whether the full-capacity resource utilization rate of the multi-layer network base station after re-expansion exceeds a preset upper limit threshold value;
and completing capacity expansion by all the new network layers added in the steps.
Specifically, the embodiment of the present invention provides another scheme in the case that the full capacity resource utilization rate of the expanded multi-layer network base station still exceeds the preset upper threshold, if the full capacity resource utilization rate still exceeds the preset upper threshold, step 1001: and adding the new network layer to expand the capacity of the multi-layer network base station, and step 1002: calculating the full capacity resource utilization of the latest multi-layer network base station based on the newly added multi-layer network base station after the capacity expansion of the new network layer, and step 1003: and judging whether the full capacity resource utilization rate of the latest multi-layer network base station exceeds a preset upper limit threshold value, if so, returning to the step 1001, and repeating the steps 1001-1004 until the full capacity resource utilization rate of the multi-layer network base station after the last capacity expansion does not exceed the preset upper limit threshold value. And finally, after the result that the full capacity resource utilization rate of the multi-layer network base station does not exceed the preset upper limit threshold value is obtained through multiple capacity expansion, the capacity expansion is completed by taking the multiple capacity expansion as a final capacity expansion strategy.
Based on any one of the above embodiments, in the method, the following steps are repeated until the full capacity resource utilization rate of the multi-layer network base station does not exceed the preset upper limit threshold, and if the repetition number exceeds the preset threshold, the carrier configuration bandwidth of the new network layer is adjusted to an upper level.
Specifically, based on the foregoing, the carrier configuration bandwidth of the new network layer for capacity expansion is generally 20M, 40M, 60M, 80M or 100M, and after it is determined that the carrier configuration bandwidth of the new network layer to be added first is preferably the lowest level bandwidth, that is, 20M in the above example, in the process of recycling and iterating, if the iteration number exceeds a certain threshold and the full capacity resource utilization of the whole station cannot exceed the preset upper limit threshold, it means that the step size is too small, so that the carrier configuration bandwidth of the new network layer is increased by one step each time, and for the first upgrade, that is, from 20M to 40M in the above example, if the carrier configuration bandwidth of the new network layer is changed to 40M, the iterative calculation of the full capacity resource utilization of the whole station is continued, or if the iteration number exceeds the certain threshold, the carrier configuration bandwidth of the new network layer is continued to be upgraded, that is increased from 40M to 60M until the last step in the above example. Thus, the method for adjusting the carrier configuration bandwidth of the new network layer from the lowest level of sequential upgrading is to find the optimal balance point between the capacity expansion precision and the iteration time duration.
Based on any of the above embodiments, the method further includes:
And if the actual flow does not exceed the preset calibration value, performing interference elimination processing on the multi-layer network base station.
Specifically, after determining that the full capacity resource utilization exceeds the preset upper limit threshold, if it is determined that the actual traffic of the multi-layer network base station does not exceed the preset calibration value, it may be determined that the problem of high load of the base station caused by interference (which is represented by that the full capacity resource utilization exceeds the preset upper limit threshold), and therefore, it is recommended to use a network optimization method to eliminate interference.
The method provided by the embodiment of the invention realizes the interference elimination processing after the interference problem of the base station is detected, and reduces the operation load of the base station.
Based on any of the above embodiments, in the method,
The full capacity resource utilization rate is determined based on the base station busy hour utilization rate, the target spectrum efficiency and the configuration bandwidth of each layer of network carrier of the multi-layer network base station;
the preset calibration value is determined based on target spectrum efficiency and configuration bandwidth of each layer of network carrier of the multi-layer network base station.
Specifically, the full capacity resource utilization δ total of the multi-layer network base station is calculated by the following formula:
If delta total is larger than a preset proportion threshold value, determining that the full capacity resource utilization rate of the multi-layer network base station exceeds the standard;
correspondingly, the method for determining that the actual flow of the whole station of the multi-layer network base station is not out of standard specifically comprises the following steps:
the preset calibration value S ref of the total station capacity flow is calculated by the following formula:
If the actual flow of the whole station of the multi-layer network base station does not exceed S ref, determining that the actual flow of the whole station of the multi-layer network base station does not exceed the standard.
Wherein N is the number of network layers of the multi-layer network base station, δ i is the base station busy time utilization rate of the i-layer network carrier, and is a current network common index, and can be directly obtained from network management equipment. Alpha i is the target spectrum efficiency of the i-layer network carrier (unit: mbps/MHz, sampling period is the hour of the day when the base station traffic is maximum, i.e. the base station is busy); the target spectrum efficiency is the service carrying capacity which should be achieved by the carrier wave, and factors such as the frequency band height, the equipment processing capacity and the like are all related, the value can be obtained from the existing test data, and different standard carrier waves have typical experience values, for example, the target spectrum efficiency of the 4G TDD standard carrier wave (2.6 GHz) is generally 0.57Mbps/MHz, which means that 0.57Mbps of data can be transmitted within one second per 1MHz frequency band. Beta i is the configuration bandwidth (unit: MHz) of each layer of network carrier, and the parameter is the basic configuration data of the base station, and can be directly obtained from the network manager. And calculating the full capacity resource utilization rate delta total of the target base station based on the formula, comparing the full capacity resource utilization rate delta total with a given preset upper limit threshold, wherein the typical value of the given preset upper limit threshold is 50%, judging whether the actual flow exceeds a preset calibration value if the typical value exceeds the threshold, and if the actual flow does not exceed the preset calibration value, indicating that the high load problem does not exist, and directly ending the flow. Then, calculating a preset calibration value of the whole station full capacity flow of the target base station by using the formula, and simultaneously acquiring the actual bearing flow (unit: megabit) of the base station when the network is busy; if the actual bearing flow is greater than the preset calibration value in busy hours, the high-load base station which is required to be expanded is judged, and a specific expansion configuration scheme is calculated in the next step; if the flow calibration value is not reached, the problem of interference exists due to the fact that the bearing efficiency is too low, and an optimization method is recommended to eliminate interference instead of blind capacity expansion.
The method provided by the embodiment of the invention has the advantages that the calculation formula of the full-capacity resource utilization rate of the whole station can calculate the whole load state of the base station based on the capacity and the utilization rate of all carriers of the multi-layer network base station, and the problem of interlayer load imbalance caused by independent evaluation of single carrier in the prior art is solved; the full capacity flow preset calibration value accounting mode is used for calculating the full capacity flow preset calibration value of the base station based on the target spectrum efficiency and the configuration bandwidth of each layer of carrier waves, and the capacity capacities of the carriers of different technical systems of the multi-layer network can be normalized to obtain the total service bearing capacity which the base station should reach.
Based on any of the above embodiments, in the method, the preset upper threshold is 50%.
Specifically, the range of the preset upper threshold is usually 50% -70%, and the embodiment of the invention limits the value of the preset upper threshold to 50%. Further, performing capacity expansion processing on the multi-layer network base station specifically includes:
adding a new network layer capacity expansion mechanism to the multi-layer network base station each time, and for the jth capacity expansion, if the full capacity resource utilization delta total,j of the multi-layer network base station after the jth capacity expansion does not exceed the preset proportion threshold value, adding j new network layers to complete capacity expansion;
Wherein j is a positive integer, delta total,j is determined based on the busy time utilization rate, target spectrum efficiency and configuration bandwidth of each layer of network carrier of the multi-layer network base station added with j new network layers, and if j exceeds a preset threshold, the carrier configuration bandwidth of the new network layers is adjusted to the upper level;
Still further, the method further comprises the steps of, When i is less than or equal to N, delta i is the utilization rate of the base station of the ith layer network carrier of the multi-layer network base station in busy hours, alpha i is the target spectrum efficiency of the ith layer network carrier of the multi-layer network base station, and beta i is the configuration bandwidth of the ith layer network carrier of the multi-layer network base station; when N < i is less than or equal to j+n, δ i is the base station busy time utilization rate of the new network layer carrier, α i is the target spectrum efficiency of the new network layer carrier, and β i is the configuration bandwidth of the new network layer carrier; and if j exceeds a preset threshold value, the carrier configuration bandwidth of the new network layer is adjusted to be higher level. The capacity expansion processing of the multi-layer network base station is described by the formula, the fact that j times of capacity expansion are needed to obtain a final capacity expansion strategy is pointed out, the iteration stopping condition is that the full capacity resource utilization rate delta total,j of the multi-layer network base station after j times of capacity expansion does not exceed the preset proportion threshold, and finally j new network layers are added to serve as capacity expansion strategies to complete capacity expansion. It should be noted that if j exceeds the predetermined threshold, the carrier configuration bandwidth of the new network layer is adjusted to the upper level, that is, if the number of iterations is too large, the carrier configuration bandwidth of the new network layer is set to the upper level bandwidth value, for example, the carrier configuration bandwidth of the new network layer for capacity expansion is usually 20M, 40M, 60M, 80M or 100M, and after it is determined that capacity expansion is required, the carrier configuration bandwidth of the new network layer added first is preferably the lowest level bandwidth, that is, 20M in the above example, in the process of recycling and iterating, if j exceeds a certain threshold, the full-capacity resource utilization of the whole station cannot reach the preset upper limit threshold, the step size is too small, so that the carrier configuration bandwidth of the new network layer is increased by one step, the first upgrade is from 20M to 40M in the above example, if the carrier configuration bandwidth of the new network layer is changed to 40M, the iterative computation of the full-capacity resource utilization rate of the whole station is continued, or the number of iterations exceeds the certain threshold, the upgrade is continued, in the above example, the carrier configuration bandwidth of the new network layer is increased from 40M to 60M until the last stage. Thus, the method for adjusting the carrier configuration bandwidth of the new network layer from the lowest level of sequential upgrading is to find the optimal balance point between the capacity expansion precision and the iteration time duration.
Based on any one of the above embodiments, the embodiment of the present invention provides a mobile communication network capacity allocation device for a multi-layer network, and fig. 2 is a schematic structural diagram of the mobile communication network capacity allocation device for a multi-layer network provided by the embodiment of the present invention. As shown in fig. 2, the apparatus includes a first determining unit 210, a second determining unit 220, and a capacity expanding unit 230, wherein,
The first determining unit 210 is configured to determine whether a full capacity resource utilization rate of the multi-layer network base station exceeds a preset upper limit threshold;
