Description

Method and device for offloading data services

technical field

The present invention relates to the technical field of communication, in particular to a method and device for distributing data services.

Background technique

Time-division (English: TimeDivision, abbreviation: TD) data service refers to providing users with video, entertainment, sports, music, web browsing and other types of services based on mobile networks through TD terminals. TD data services are generally interactive data services, including Time Division Synchronous Code Division Multiple Access (English: TimeDivisionSynchronousCodeDivisionMultipleAccess, abbreviation: TD-SCDMA) data services (hereinafter referred to as TDS data services) and Time Division Long Term Evolution (English: TimeDivisionLongTermEvolution, abbreviation: TD-LTE) data service (hereinafter referred to as TDL data service for short).

With the continuous development and deepening of the TD data service scale, the number of users has shown a steady increase, and the network utilization rate has been rising, which affects user perception. Network capacity has become an important factor affecting the service quality and customer perception. To solve the problem of insufficient carrier resources caused by the current TDS network user access, a common method in the existing network is to use offloading means to offload and configure data services to be carried by other standard networks. Under normal circumstances, when the number of users accessing a single network is too large to perform offload configuration, the methods often used are capacity expansion, frequency point compression, and offload to different networks.

The first method: the method of realizing data traffic offload configuration by means of capacity expansion refers to solving the capacity problem by increasing network resource configuration.

However, this method will increase the investment cost of network resources, be limited by hardware configuration and other problems, and high-configuration cells will cause problems such as increased frequency point interference.

The second method: the method of realizing service data distribution configuration by means of frequency point compression refers to compressing the interval between frequency points of the existing TDS network to increase the number of available frequency points to increase capacity.

But this approach will increase the downlink interference of the TDS network.

However, there are three methods: realize the configuration of business data distribution by means of distribution to different networks, modify the switching bias of neighboring cells in the network, the interoperability bias of neighboring cells of different networks, and modify the network measurement threshold to make the relatively idle local network or Different network neighbors to share the business data of the busy cell.

However, the distribution parameters of the existing network are configured based on the overall situation of the entire network, without considering different regional scenarios and service distribution. This kind of distribution method cannot meet the distribution requirements of different regions.

To sum up, the existing technical solutions for offloading data services have relatively large limitations and have a certain impact on user perception.

The main realization principles, specific implementation methods and corresponding beneficial effects of the technical solutions of the embodiments of the present invention will be described in detail below with reference to each accompanying drawing.

Embodiment one

Embodiment 1 of the present invention proposes a method for offloading data services, as shown in FIG. 1 , and its specific processing flow is as follows:

Step 11, acquiring the radio resource utilization rate of each cell in different scenarios.

In different scenarios, the TDS data service and the TDL data service in the same cell have their own distribution characteristics. According to the analysis of the data obtained in the traffic system, the distribution characteristics of the TDS data service and the TDL data service are obtained, and then the wireless resource utilization rate of each cell in different scenarios is determined.

In the technical solution proposed by the embodiment of the present invention, firstly determine the distribution analysis and service characteristics of TDS data service and TDL data service in the cells of different scenarios, and determine whether the cell can perform data traffic offloading.

Among them, collect and analyze the distribution of data services to determine whether it is necessary to carry out targeted data service distribution in different data types of communities and different regions. Data packets can be obtained through a radio network controller (English: Radio Network Controller, abbreviation: RNC) in the system, and the distribution characteristics of data services in different regions can be obtained by analyzing the obtained data packets. For example, in certain scenarios, the weight of some data services is relatively high. For example, in densely populated areas such as office buildings and residential buildings, more users use web browsing services, while in macro station scenarios, more users use instant services and WAP web browsing. By analyzing the distribution of data services, it can be determined whether it is necessary to perform targeted data service distribution in different data types of cells and different regions, which can better improve user perception.

By collecting and analyzing data business segments, the proportions of TDS data services and TDL data services in the system can be obtained. For example, compare the growth of business data between the TDS network and the TDL network from the establishment of the network to the current situation, and judge the distribution of users holding terminals supporting the TDL network in different scenarios. At present, because the TDL network is in its infancy, in some scenarios, the number of distributed users supporting the TDL network is small, so that the amount of data traffic that can be offloaded to the TDS is limited. However, in some special scenarios, there are many users supporting the TDL network. At this time, multiple adjustments are required when determining the reselection parameters, which can better improve user perception.

A preferred implementation manner, in the technical solution proposed in Embodiment 1 of the present invention, based on the traffic volume of TDS data service and TDL data service, scenarios are divided into four types, specifically as follows:

The first type: both the TDS data service carried on the TDS network and the TDL data service carried on the TDL network are in a high load state.

The second type: the TDS data service carried on the TDS network is in a high-load state, and the TDL data service carried on the TDL network is in a low-load state.

The third type: the TDS data service carried on the TDS network is in a low-load state, and the TDL data service carried on the TDL network is in a high-load state.

The fourth type: both the TDS data service carried on the TDS network and the TDL data service carried on the TDL network are in a low load state.

In the technical solution proposed by the embodiment of the present invention, the business data distribution is mainly realized for the above-mentioned second type of scenario and the third type of scenario. A scene of type does not exist. Based on this, the embodiment of the present invention takes the above-mentioned second type of scenario as an example to elaborate a method for data traffic offloading. According to the analysis, it can be seen that the utilization rate of TDS network resources in commercial centers, residential areas, township areas, and transportation hubs is higher than 28%, while the growth of TDL services is relatively slow. From the perspective of the correlation with business volume growth, transportation hubs, commercial centers and The business volume in residential areas is more relevant, so it is necessary to separate business data for scenarios such as transportation hubs, commercial centers, and residential areas.

Secondly, the correlation and service characteristics between the TDS data service and the TDL data service in each regional scenario are determined. According to the statistical analysis of the traffic, the uplink and downlink business data traffic of the TDS network and the TDL network can be obtained, and the uplink and downlink business data traffic of the TDS network and the TDL network can be obtained, and then the area covered by the signal transmitted by each base station can be estimated According to the distribution of TDS and TDL user numbers, the reselection parameters are adjusted according to different distribution characteristics. The proportion of TDS and TDL services in the region is obtained through statistics by time period. By debugging the current network parameters, the most suitable reselection parameters for each data service situation are obtained, so as to realize data service distribution without reducing user perception.

The radio resource utilization rate of the cell can be obtained through the code resource utilization rate.

Step 12, according to the radio resource utilization rate, calculate the reselection parameters of the cell for handover between the TD-SCDMA network and the TD-LTE network in different scenarios.

For example, a commercial center area is selected as the data service offloading area. By analyzing the service data carried by the TDS network and the TDL network, the analysis shows that the average wireless resource utilization rate of TDS and TDL in this area is 31.87% and 5.61% on weekends, and the average wireless resource utilization rate on weekdays is 31.87%. The average wireless resource utilization rate of TDS and TDL is 27.31% and 3.1%, then the reselection parameter of TD-SCDMA network to TD-LTE network on weekdays in this area is set to -114, TD-LTE network to TD-SCDMA network The reselection parameter of the offload is set to -120, the reselection parameter of the weekend TD-SCDMA network to the TD-LTE network is set to -112, the reselection parameter of the TD-LTE network to the TD-SCDMA network is set to - 120.

Wherein, the first threshold value is greater than the second threshold value and greater than the third threshold value. When determining the belonging category of the cell, determine the self-busy time of the cell, which refers to the hour when the data service of the cell is the busiest within 24 hours. For each cell in different scenarios:

The first category: high-value diversion community. When it is determined that the code resource utilization rate of the cell is greater than the set threshold when the cell is busy, and the average daily data traffic flow of the cell is greater than the first threshold, it is determined that the cell belongs to a high-value offload cell when the cell performs data service offload.

The second category: mid-value diversion community. When it is determined that the code resource utilization rate of the cell is greater than the set threshold when the cell is busy, and the daily average data traffic flow of the cell is less than the first threshold value, and the daily average data traffic flow of the cell is greater than the second threshold value, determine the cell When the data service is offloaded, the attribution category of the cell is a medium-value offload cell.

Step 231, when it is determined that the code resource utilization rate of the cell is lower than the first set threshold when the cell is busy, determine whether the code resource utilization rate of the cell is lower than the second set threshold when the cell is busy. If the judgment result is yes, execute step 232 , otherwise, execute step 29 .

A preferred embodiment, the present invention implements a proposed technical solution, the first set threshold is 30%, and the second set threshold is 15%, that is, when it is determined that the cell is self-busy, the code resource utilization rate is less than When 30%, it is determined whether the code resource utilization rate of the cell is lower than 15% when the cell is busy. If the judgment result is yes, step 232 is performed; otherwise, step 29 is performed.

Step 232, when it is determined that the code resource utilization rate of the cell is lower than the second set threshold when the cell is busy, determine whether the carrier configuration of the cell is greater than 1 carrier, if the judgment result is yes, execute step 233, otherwise, if the judgment result is If no, go to step 29.

In step 233, it is determined that the carrier configuration of the cell is greater than 1 carrier, then the cell is an idle cell, and data traffic offloading is not required.

The cell can be identified as an idle cell to facilitate subsequent optimization processing.

In step 241, it is determined that the attribution type of the cell is a high-value offloading cell when the cell performs offloading of data services, and reselection parameters are configured for the cell.

Step 25, determine whether the average daily data traffic flow of the cell is greater than the second threshold value, if the judgment result is no, execute step 26, otherwise, if the judgment result is yes, execute step 251.

A preferred embodiment, in the technical solution proposed by the present invention, the second threshold value is 100M, that is, to determine whether the daily average data traffic flow of the community is greater than 100M, if the judgment result is no, then perform the steps 26. On the contrary, if the judgment result is yes, go to step 251.

In step 251, it is determined that the attribution category of the cell when the cell performs data service offloading is a medium-value offloading cell.

A preferred embodiment, in the technical solution proposed by the present invention, the third threshold value is 10M, that is, determine whether the daily average data traffic flow of the community is less than 10M, if the judgment result is no, then execute the step 27. On the contrary, if the judgment result is yes, go to step 232.

Step 15, according to the parameter configuration template, offload the TDS data service carried in the TD-SCDMA network and the TDL data service carried in the TD-LTE network in different scenarios.

Based on the data traffic in the TDS network and the TDL network, the configuration scheme of the reselection parameters in different scenarios is obtained through parameter calculation. For various scenarios, effectively output the configuration scheme of reselection parameters. The parameter configuration template sets the corresponding threshold according to the data traffic in the TDS network and the TDL network. When the service type of the corresponding network element exceeds or falls below the threshold, the reselection parameter of the network element is adjusted, and the coordination of the reselection parameter configuration of another network element Therefore, the parameter ratio scheme uniquely suitable for this scenario can be output. For areas with low TDS and TDL traffic volume, the parameter configuration template appropriately lowers the threshold for reselection from TDL to TDS; for areas with high TDS and TDL traffic volume, the parameter configuration template appropriately increases the threshold for TDS to TDL reselection , for areas with high TDS traffic and low TDL traffic, the parameter configuration template will jointly adjust the TDS and TDL reselection thresholds according to the traffic.

Optionally, after the above step 15, it may also include:

Periodically check the reselection parameters.

It changes the traditional distribution method of increasing capacity or controlling user bandwidth, and allocates various types of service bandwidth simply and effectively. It saves the cost of hardware investment, and at the same time enables users to occupy more and better TDL network elements and enjoy high-speed transmission services. In addition, TDL's high-quality wireless network resources can be better utilized, so that users can enjoy better services, and the simple calculation method can be used to update the reselection parameters in real time, and provide personalized reselection for different regions and different time periods parameter.
