For example, a network operator may build a network management system (NMS) that manages network conditions and failures, or create a virtual network model to predict and analyze the network's performance and use it to perform network network performance evaluation. Build simulation systems.

However, since the coverage management using these systems was focused more on expanding the coverage area of the mobile communication terminal than on the uniformity of traffic distribution, the service could not be provided based on the optimal wireless network quality. .

Therefore, in order to provide a service based on the optimal wireless network quality to the user, there is a demand for a method of preventing traffic load by uniformly distributing the traffic of the base station.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a connection relationship between a wireless network optimization system and a communication network according to the present invention.

The Radio Access Network Optimizer (RANO) 200 is a WiBro (Wireless Broadband) 100 and a CellPLAN (CellPLAN) for communicating with the mobile communication terminal 10. 300 is connected to transmit and receive a signal, to identify the traffic emitted from the at least one mobile communication terminal 10 in a specific base station to produce a traffic morphology (Morphology), based on this to select a base station to distribute traffic In addition, traffic distribution is performed for the selected base station.                     

2 is a view showing the configuration of a wireless network optimization system according to the present invention.

The wireless network optimization system 200 may include a control unit 210 for controlling the overall operation of the wireless network optimization system 200, a database 260 storing related information of the wireless network optimization system 200, and each of the base station sectors or repeaters. A traffic morphology generation unit 220 for distributing traffic to generate a traffic morphology, a base station selecting unit 230 for selecting a base station to distribute traffic, a traffic management unit 240 for distributing traffic uniformly, and a traffic management unit 240 for changing traffic It includes an antenna manager 250 that provides an operation plan of the antenna that can be implemented on the coverage.

In more detail, the database 260 may include the traffic morphology information DB 261 storing the traffic morphology information generated by the traffic morphology generation unit 220, the collected traffic information, and a predetermined reference traffic margin value, and the traffic management unit ( A traffic distribution result information DB 263 for storing traffic distribution result information for each region for a region where traffic is distributed by 240; and an antenna information DB 265 for storing antenna operation information that may be implemented in a plurality of situations. do.

The traffic morphology generation unit 220 configures the GIS data in bin units, which are the minimum units when generating the electronic map data, under the control of the control unit 210, and each bin is the time zone during which the most traffic of the day is at the highest time. Based on the distribution of the traffic of a plurality of base stations in the Erlang (Erlang) unit. Here, 1 Erl (Erlang) means the maximum call volume that one line can transmit.

For example, if 30 Erlang traffic is distributed in a sector of a base station, and the coverage of the sector is composed of 100 bins, 0.3 Erlang is distributed in one bin.

In this case, when there is no location information of the mobile communication terminal 10 generating the traffic, the traffic morphology generation unit 220 calculates the traffic for each of the base station sector and the repeater, and distributes the traffic uniformly to each sector and the repeater coverage. When there is location information of the mobile communication terminal 10 that generated the traffic, the traffic generated from the mobile communication terminal 10 is uniformly distributed within a predetermined range considering an error from the location of the mobile communication terminal 10.

The base station selecting unit 230 selects a base station to perform radio network capacity increase by comparing each busy hour traffic margin value for a plurality of base stations with a reference traffic margin value preset by an operator.

Here, the busy hour traffic margin value means a value representing the capacity of the base station to accommodate additional traffic at the time of the day when the traffic of the base station is the highest (for example, the free traffic capacity of the base station). In addition, the preset reference traffic margin value refers to a reference value of the capacity left as a margin for the base station to accommodate the traffic.

The traffic management unit 240 includes a traffic distribution means 241 for each sector that performs traffic distribution between sectors and a traffic distribution means 243 for each base station that performs traffic distribution between base stations, and is selected by the base station selecting unit 230. Determining whether to perform intersector traffic distribution or interstation traffic distribution for each base station to increase the capacity, and distribute the traffic using any one of the distribution means according to the determined method. .

Here, the traffic manager 240 distributes the traffic by using the traffic distribution means 241 for each sector when the deviation of the traffic between sectors of the base station exceeds a preset reference value.

First, the traffic distribution means for each sector 241 checks whether there is a repeater sharing coverage with the neighboring sector in the sector having the most traffic, and if there is a repeater sharing coverage with the neighboring sector, the sector having the most traffic is determined. A repeater sector change process is performed to change to an adjacent sector.

If there is no repeater sharing coverage with an adjacent sector, or even if the traffic deviation between sectors is equal to or larger than a predetermined reference value even after performing a repeater sector change process, the sector-specific traffic distributing means 241 gradually increases the sector width of the sector having the most traffic. A native coverage change procedure is performed, which simultaneously decreases and increases the sector width of other sectors. Then, the traffic distribution means for each sector 241, if the direction of the repeater and the sector direction of the home station (for example, the direction of the antenna) does not match with the sector width change, so that the direction of the repeater and the sector direction of the home station to match Change the sector of the repeater.

In addition, the sector-specific traffic distributing means 241 transmits the result information to the cell plan 300 after performing the repeater sector change process and the mother country coverage change process, and requests to simulate the coverage change and the traffic load per sector, and the cell. According to the simulation result transmitted from the plan 300, it is determined whether the inter-sector traffic ratio is optimal and determines whether to repeat the traffic distribution process.

Secondly, the traffic distributing means 243 for each base station selects six adjacent base stations in order of sharing the most coverage based on the base station to perform traffic distribution, and performs traffic distribution for each of the selected base stations. Even when the distributed target traffic of the base station is received, the base station whose busy time traffic margin is greater than or equal to the preset busy time reference traffic margin is examined.

For example, if the capacity criterion of the base station is 50 Erlang and the busy time margin is set to 20%, the traffic distributing means 243 for each base station manages the traffic amount to keep the traffic of the base station at 40 Erlang or less. If the busy hour traffic of base station A is 46 Erlang, the base station traffic distributing means 243 is a base station B, C base station, D in order to share the coverage with the base station A to distribute the traffic 6 Erlang of the base station A to other base stations; A base station, an E base station, an F base station, and a G base station are selected, and the base station is searched for a base station in which the traffic does not exceed 40 Erlang even when traffic 6 Erlang of the A base station is accommodated.

Then, when the base station to distribute the traffic of the base station A is selected, the traffic distribution means 243 performs the coverage boundary adjustment between the base station A and the base station to distribute the traffic of the base station A. In this case, the coverage boundary adjustment is performed in bin units.

In addition, the traffic distribution means 243 for each base station performs a coverage change process between base stations, and then transmits the result information to the cell plan 300 to request simulation of the coverage change and the traffic load for each sector, and the cell plan 300. Based on the simulation result transmitted from the server, it is determined whether the traffic distribution process through coverage boundary adjustment is repeated.

The antenna manager 250 extracts an antenna operation plan that can be implemented on the coverage changed by the traffic manager 250 from the antenna information DB 265, and provides the antenna operation plan to the operator's terminal (not shown) so that the operator can check it. .

3 is a flowchart illustrating an embodiment of a method for optimizing a wireless network according to the present invention.

The traffic morphology generation unit 220 of the wireless network optimization system 200 configures the GIS data in bin units, which are the minimum units when generating the electronic map data, and each bin has a time zone during which the traffic has the most traffic during the day. The traffic morphology is generated by distributing traffic of a plurality of base stations in units of Erlang based on the S (S101).

Here, if there is no location information of the mobile communication terminal 10, the traffic morphology generation unit 220 calculates traffic for each sector and repeater of the base station, and distributes traffic uniformly to each sector and coverage, and the mobile communication terminal ( When there is the location information of 10), the traffic generated from the mobile communication terminal 10 is uniformly distributed in the range in which the mobile communication terminal 10 can be located in consideration of the error of the location information.

Subsequently, the base station selecting unit 230 compares the busy hour traffic margin value of each of the plurality of base stations with the reference traffic margin value preset by the operator in order to select a base station to perform the capacity increase of the wireless network (S103).

Here, the busy hour traffic margin value refers to a value representing a capacity for accommodating additional traffic by the base station (eg, the free traffic capacity of the base station) at the time when the base station has the most traffic. In addition, the preset reference traffic margin value refers to a reference value of the capacity left as a margin for the base station to accommodate the traffic.

As a result of step S103, when the busy hour traffic margin of the base station is less than the reference traffic margin preset by the operator, the base station selecting unit 230 selects the base station as a base station to increase the wireless network capacity.

Subsequently, the traffic manager 240 determines whether to perform inter-sector traffic distribution or inter-base station traffic distribution for each base station selected by the base station selecting unit 230 (S105).

According to the result of step S105, the traffic manager 240 performs traffic distribution between base stations or traffic distribution between sectors (S107, S109).

Here, the traffic manager 240 distributes traffic according to the sector-to-sector distribution method when the deviation of traffic between sectors of the base station exceeds a preset reference value.

On the other hand, as a result of step S103, when the busy hour traffic margin of the base station is greater than or equal to the reference traffic margin preset by the operator, the process subsequent to step S103 is repeated for another base station.

A detailed description of the step S107 of performing traffic distribution between base stations and the step S109 of performing traffic distribution between sectors will be described later with reference to FIGS. 4 and 5.

4 is a flowchart illustrating a method for distributing traffic between sectors according to the present invention, which is a flowchart illustrating step S109 of FIG. 3 in detail.

The sector-specific traffic distributing means 241 of the wireless network optimization system 200 checks whether there is a repeater sharing coverage with an adjacent sector in the base station sector with the most traffic (S201).

As a result of step S201, when there is a repeater sharing coverage with the neighboring sector, the traffic distribution means for each sector 241 performs a repeater sector changing process for changing the sector with the most traffic to the neighboring sector (S203).

Thereafter, the traffic distribution means for each sector 241 performs a sector change process of the repeater, and then transmits the result information to the cell plan 300 to request to simulate the coverage change and the traffic load for each sector, and from the cell plan 300. The simulation result transmitted is received (S205).

Subsequently, the traffic distribution means for each sector 241 checks the simulation result to determine whether the traffic deviation of the corresponding sector that has performed the traffic distribution exceeds a predetermined reference value, and determines whether to repeat the traffic distribution process. (S207).

If the traffic deviation in step S207 does not exceed the preset reference value, the traffic distribution means for each sector 241 stores the traffic distribution result for each sector in the traffic distribution result information DB 263 (S209).

On the other hand, if there is no repeater sharing coverage with the adjacent sectors as a result of step S201, the sector-specific traffic distributing means 241 gradually decreases the sector width of the sector with the most traffic, and at the same time increases the sector width of the other sectors. A mother country coverage change process is performed (S211).

Thereafter, the traffic distribution means for each sector 241 performs a sector change process of the repeater, and then transmits the result information to the cell plan 300 to request to simulate the coverage change and the traffic load for each sector, and from the cell plan 300. Receive the transmitted simulation result (S213).

Subsequently, the traffic distribution means for each sector 241 checks the simulation result received in step S213 to determine whether the sector width changing process should be repeated (S215).

On the other hand, when the sector width change is not necessary as a result of step S215, the traffic distribution means for each sector 241 performs the process after step S209.

On the other hand, when the sector width change is necessary as a result of step S215, the sector-specific traffic distributing means 241 performs the process after step S211.

In addition, when the traffic deviation exceeds the predetermined reference value in step S207, the traffic distribution means for each sector 241 performs the procedure after S211.

5 is a flowchart illustrating a method for distributing traffic between base stations according to the present invention, which is a detailed flowchart illustrating step S107 of FIG. 3.

The traffic distribution means 243 for each base station selects six neighboring base stations in order of sharing the most coverage based on the base station to perform traffic distribution (S301).

Subsequently, the traffic distributing means 243 for each base station selects the busy hour traffic when the busy hour traffic is preset even if the distributed target traffic of the base station to perform traffic distribution is performed in the order of the base stations which share much coverage among the base stations selected in step S301. It is checked whether the reference value is exceeded (S303).

For example, if the capacity criterion of the base station is 50 Erlang and the busy time margin is set to 20%, the traffic distribution means 243 for each base station manages traffic distribution to keep the traffic of the base station at 40 Erlang or less. If the busy hour traffic of base station A is 46 Erlang, the base station traffic distributing means 243 is a base station B, C base station, D in order to share the coverage with the base station A to distribute the traffic 6 Erlang of the base station A to other base stations; A base station, an E base station, an F base station, and a G base station are selected, and a base station in which the traffic is not exceeding 40 Erlang is selected even when the six traffics of the A base station are accommodated.

As a result of step S303, when the busy hour traffic does not exceed the preset busy hour traffic reference value, the traffic distribution means 243 for each base station performs coverage boundary adjustment between the base station to increase the wireless network capacity and the base station to receive the traffic. (S305). In this case, the coverage boundary adjustment is performed in bin units.

Thereafter, the base station traffic distributing means 243 performs a base station coverage change process, and then transmits the result information to the cell plan 300 to request to simulate the coverage change and the traffic load for each sector, and from the cell plan 300. The simulation result transmitted is received (S307).

Subsequently, the base station traffic distributing means 243 checks the simulation result received in step S307, and determines whether to terminate coverage demarcation between base stations according to whether the traffic distribution target value is satisfied (S309). Here, the traffic distribution target means the amount of traffic to be distributed from the base station to distribute the traffic.

If the result traffic distribution target value of step S309 is satisfied, the traffic distribution means 243 for each base station stores the coverage change result in the traffic distribution result information DB 263.

On the other hand, when the traffic distribution target value is not satisfied as a result of step S309, the traffic distribution means 243 for each base station performs the procedure after step S305.

In addition, as a result of step S303, when the busy hour traffic exceeds a preset busy hour traffic reference value, the traffic distribution means 243 for each base station may select a base station to receive the traffic of the base station to increase the wireless network capacity to other base stations. The step S303 of selecting is repeated.

As such, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, the above-described embodiments are to be understood as illustrative in all respects and not as restrictive. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.
