Description

Network data flow balancing method and system

Technical Field

The present invention relates to the field of communication and wireless data technologies, and in particular, to a method and a system for balancing network data traffic.

Background

Currently, in a Mobile communication Network, there are multiple GSM (Global System for Mobile Communications), TD-SCDMA (Time Division-Synchronous Code Division multiple access), WLAN (Wireless Local Area Network) and LTE (Long Term Evolution) networks. With the rapid development of mobile data services and the gradual increase of service volume, the data traffic of each network is unbalanced due to the factors of the development of each network, the difference of service carrying capacity and the like. Especially, the GSM network and TD-SCDMA network have high load in some areas, which seriously affects the network quality and user experience.

The current data flow balancing strategy mainly considers the shunting of a high-load GSM network to TD-SCDMA and WLAN networks. The main shunting means includes new station, interoperation parameter adjustment of GSM and TD-SCDMA, TD-SCDMA capacity expansion, and shunting according to information such as network type and terminal number supported by the terminal.

On the other hand, the LTE network is already in commercial use and is being developed for large-scale construction, and the LTE technology can bring higher transmission rate, higher communication quality and better user perception. Therefore, the LTE network will become the best shunt option for high-load GSM and TD-SCDMA. However, currently, the large-scale construction of LTE mainly considers the planning construction target of deep coverage and wide coverage, and does not consider offloading.

To sum up, the traffic between the networks is actually unbalanced, and the load of part of the networks is high, and the network is to be shunted urgently. However, the current shunting (flow equalization) strategy and shunting (flow equalization) method have the following disadvantages:

1. the current shunting lacks systematicness, and can not evaluate the shunting necessity from the network overall angle and position the main problems of shunting; 2. at present, the network mainly considers the distribution of a high-load GSM network to a TD-SCDMA network and a WLAN network, and the distribution of the GSM network and the TD-SCDMA network to an LTE network is not considered temporarily; 3. in the existing site selection and construction of LTE, deep coverage and wide coverage are mainly considered, and shunting factors are not considered temporarily; 4. at present, the interoperation parameter adjustment of GSM and TD-SCDMA is mainly considered, and the interoperation parameter adjustment of GSM, TD-SCDMA and LTE mainly considers the normal operation of the network and temporarily does not consider the shunting factor; 5. at present, user popularization and service popularization of LTE are mainly considered based on factors such as market and business, and shunting factors are not considered temporarily; 6. at present, the expansion evaluation of TD-SCDMA is mainly considered, and the expansion evaluation of LTE is not considered temporarily; 7. in the prior art, a shunt network is determined to shunt according to information such as network types supported by a terminal, terminal data and the like, and the method has the defects that the shunt network cannot be shunted to network types which cannot be supported by the terminal, and the shunt network can only be shunted according to the network types and the number of the terminals supported by the terminal, so that the data service flow conditions and the resource occupation conditions of the actual network and the terminal cannot be reflected, and the shunt is unreasonable sometimes.

when the TD cell is in the same site and the same coverage GSM, the same coverage 3G flow resident ratio is equal to that in the same coverage area, and the cell flow of the TD cell/(the cell flow of the TD cell + the TD terminal flow of the same coverage 2G cell) is multiplied by 100%; or when there is no score data, calculating the traffic retention ratio by using a Key Performance Indicator (KPI), namely, a method 2 for calculating the traffic retention ratio is as follows:

when the TD cell meets the condition of same site and same coverage GSM, the same coverage TD flow dwell ratio is equal to the cell flow of the TD cell/(the cell flow of the TD cell + the cell flow of the same coverage 2G cell) multiplied by 100% in the same coverage area. The unit of the cell traffic is MB.

For the target shunting cells, whether the target shunting cells are user popularization cells or not can be further judged; that is, the conditions are satisfied, the number of TD terminals is 10 (a first value), and the TD terminal traffic is 100M (a second value), then the target offload cell is the user promotion cell.

Further, the step of determining that the target shunt network is a 4G network includes:

determining that the target shunt network is a 4G target shunt cell in the 4G network by the algorithm 10:

the cell network type is a 4G network, and in an LTE network cell with the same site and coverage GSM or TD (or the same site and coverage GSM or TD high-value cell), the LTE flow resident ratio is less than 75%, and the cell with the LTE network wireless resource utilization ratio less than 50% is a target shunting cell;

the LTE traffic camping ratio is the daily average cell traffic of the LTE cell/(LTE daily average cell traffic + gsm LTE terminal traffic of the same coverage + TDLTE terminal traffic of the same coverage);

and if the ' daily average cell traffic '/(LTE ' daily average cell traffic ' + with covering GSM ' LTE terminal traffic (MB) + with covering TD ' LTE terminal traffic ') of the LTE cell is smaller than a threshold (for example, 50%) and the busy hour radio resource utilization rate (reference extension definition is defined, and the maximum value of the three) of the LTE is smaller than the threshold (for example, 75%), outputting the LTE cells and simultaneously outputting the same-site/covering GSM and TD cells.

Or when there is no score data, the method 4 for calculating the traffic retention ratio by using the Key Performance Indicator (KPI), that is, the traffic retention ratio, is as follows:

the traffic camping ratio of the LTE cell is the daily average cell traffic of the LTE cell/(LTE daily average cell traffic + GSM daily average cell traffic of the same coverage + TD daily average cell traffic of the same coverage).

And if the LTE cell's ' daily average cell flow '/(LTE ' daily average cell flow ' + GSM ' daily average cell flow ' + TD ' daily average cell flow ' of same coverage) is less than a threshold (for example < 50%) and the LTE radio resource utilization rate is less than a threshold (for example < 50%), outputting the LTE cells and simultaneously outputting the GSM and TD cells of same site/coverage.

For the target shunting cells, whether the target shunting cells are user popularization cells or not can be further judged; that is, the conditions are satisfied, the number of LTE terminals is 10 (a first value), and the LTE terminal traffic is 100M (a second value), then the target offload cell is the user popularization cell.

step 122, the flow of the network area to be shunted is shunted to the target shunt network area for shunting through interoperation parameter adjustment; and/or step 123, the traffic of the network area to be shunted is shunted to the target shunt network area through user or service promotion.

In summary, the offloading strategies include interoperation parameters to be adjusted or user or service promotion, the two offloading strategies are parallel offloading strategies, one of the offloading strategies is determined to offload according to actual conditions, and if the first offloading still belongs to a high-value cell, further offloading can be performed by using the method provided by the present invention until the cell is not a high-value cell. The two shunting strategies are described in detail below:

in the embodiment of the invention, the user can more easily shunt to the target shunt network by adjusting the interoperation parameters. The interoperation parameter analysis mainly analyzes whether the interoperation parameters of the current network meet requirements, including standard or recommended value requirements. The recommended value can be preset according to the shunting requirement. And if the configured value exceeds the value specification or the checking range or reaches the abnormal parameter value judgment condition, the parameter is considered to need to be adjusted, and the adjustment range is the value specification.

TABLE 62G/3G/4G interoperable parameter-LTE cell

As shown in table 7, 2G/3G/4G interoperability-parameter-interoperation parameter of 3G cell, whether the parameter needs to be adjusted is judged according to the checking principle:

Or

Further, in the embodiment of the present invention, both the network to be shunted and the target shunt network may increase the network capacity through capacity expansion or optimization, specifically, if the network to be shunted or the target shunt network may expand the capacity, the network is expanded. The capacity expansion analysis is to analyze the capacity of the network, and mainly evaluates the conditions of the code resource utilization rate, the number of users, the cell flow, the congestion rate and the like of the cell, if the conditions are met, the cell needs to be expanded by increasing the user license or increasing the carrier frequency. TD capacity expansion and LTE capacity expansion are taken as examples here. The capacity expansion analysis can be performed for the whole network cell or only for the high-value cell or the target shunting cell. Each threshold may be self-configurable.

The 3G cell is evaluated by the following algorithm:

The 4G cells are evaluated by the following algorithm:

Specifically, the evaluation algorithm of the cell to be expanded in the T (3G) network is as follows:

algorithm 1: the method comprises the following steps that whether a TD congestion cell is a T network cell with insufficient resources (a TD cell with cell code resource utilization rate (%) being greater than 30%, a PS domain RAB congestion rate (%) being greater than 5%, and a congestion day number ratio within a statistical time range being 4/7) or not is met, and the T network cell is a T network belt capacity expansion cell;

wherein, the utilization ratio (%) of the cell code resource: the code resource utilization rate of the total cell is (the number of BRUs occupied by the uplink plus the number of BRUs occupied by the downlink)/(the number of uplink BRUs configured plus the number of downlink BRUs configured) × 100%;

PS domain RAB congestion rate (%): PS domain RAB establishment congestion times/RAB establishment request times 100%;

and 2, algorithm: when any carrier frequency in the cell meets the following conditions, the carrier frequency is a carrier frequency to be expanded, and the cell is a cell to be expanded:

1) the capacity expansion threshold of the R4 (mixed carrier frequency) is 90% of the upper limit of the busy-free rate of the code resource, namely the capacity expansion is needed when the busy-free rate of the code resource of the R4 (mixed carrier frequency) is more than 90%;

2) the busy and idle rate of the HSUPA carrier frequency code resource is more than 90%, capacity expansion is needed; ,

3) the busy-idle rate of HSDPA carrier frequency code resources is more than 85%, and the BRU bearing efficiency of an uplink DPCH channel is more than 0.7kbps, and capacity expansion is needed.

Wherein, the code resource busy-idle rate is (number of uplink occupied BRU in m × busy hour + number of downlink occupied BRU in n × busy hour)/[ K × (number of uplink available BRU + number of downlink available BRU) ]

Specifically, m and n are uplink and downlink attention factors respectively (in the present stage, m is 1, and n is 0); the meaning of the K value is that under the premise of ensuring certain network quality (GOS is 2%), the system carrying capacity is not equal to the number of channels available to the system, the ratio of the two is the K value, and the K value is a small value under the condition of interference limitation and under the condition of resource limitation; the method is suitable for R4, HSDPA, HSUPA, R4 and mixed carrier frequency, wherein the utilization rate of the HSDPA and HSUPA carrier frequency is calculated according to the utilization rate of an uplink associated channel.

LTE dilatation evaluation algorithm:

the LTE network capacity expansion comprises two types, namely local network (city) level user License capacity expansion and cell level carrier frequency capacity expansion evaluation. The specific algorithm is as follows:

1. capacity expansion judgment of local network user license:

in a statistical period, when the average value of the number of the RRC connection users is larger than the number of the purchased user licenses, the capacity expansion is carried out by increasing the user licenses. The specific expansion scale is as follows:

and (4) rounding the expansion scale of the user License (average RRC connection number at busy time at the end of the planning period-the number of the user License configured by the current network).

The average RRC connection number at the busy time at the end of the planning period is the user x activation factor at the end of the planning period. The activation factor represents the activity degree of the user using the LTE network, is related to a user service model and user distribution, has different values when the conditions of each local network are different, and is obtained by companies in various cities according to weekly statistics in actual operation. The specific definition and statistical methods are as follows: activation factor ═ (busy hour RRC connection user number average/user number × 100%);

at present, the License quotation unit of a user has 8 grades: 0.1 ten thousand, 0.5 ten thousand, 1 ten thousand, 2 ten thousand, 5 ten thousand, 10 ten thousand, 20 ten thousand, 50 ten thousand, and the user License is shared in the local network.

2. Cell carrier frequency capacity expansion judgment: (ii) a

the initial proposal of the utilization rate threshold is 100 percent, the initial proposal of the user capacity threshold is 30, and the initial proposal of the uplink/downlink flow threshold is 1GByte/5 GByte; statistical period the statistical period is recommended to be one week and the statistical data is averaged over the week. Wherein:

the utilization rate of the LTE network radio resources is MAX { the utilization rate of an uplink service channel in busy hour; the utilization rate of a downlink service channel in busy hour; busy hour control channel utilization }, wherein,

busy hour uplink traffic channel utilization rate is busy hour PUSCH PRB utilization rate is busy hour downlink PUSCH PRB occupation average/(busy hour downlink PUSCH PRB available average multiplied by K1);

busy hour downlink traffic channel utilization rate is busy hour PDSCH PRB utilization rate is busy hour uplink PDSCH PRB occupation average/busy hour uplink PDSCH PRB available average multiplied by K2);

busy hour control channel utilization rate is busy hour pdcchcch utilization rate is busy hour PDCCH CCE occupancy average/busy hour available PDCCH CCE average × K3);

meaning of K value: considering factors such as interference level control, access control and switching reserved resources in the system, the system introduces a K value for stably available resources, the value of the preliminary suggestion is K1-K2-K3-0.5, and verification and correction can be carried out subsequently according to the current network condition.

Wherein, the flow of the downlink cell is busy hour, and the number of downlink bytes of the user plane of the cell is busy; and the flow of the uplink cell is equal to the uplink byte number of the user plane of the cell in busy hour.
