Description

Method and system for balancing data services of dual-frequency co-site and co-coverage cells

technical field

The invention relates to a data service management technology in wireless communication, in particular to a method and system for balancing data services of a dual-frequency co-site and same-coverage cell.

Background technique

With the rapid growth of the global system for mobile communications (Global System for Mobile Communications, GSM) network scale and the number of users, the traffic density is also getting higher and higher. However, the wireless spectrum bandwidth resources of wireless communication operators are limited, and single frequency bands are no longer available. To meet the service requirements of users, the application of dual-band networks (such as GSM900/1800 networks) has become more and more common. However, due to various reasons, the traffic load of the dual-frequency cells covered by the same sector is seriously unbalanced, and the expected effect of dual-frequency traffic balance sharing cannot be achieved. Optimization engineers need to frequently adjust parameters to make the business conditions of the two cells basically balanced.

The equalization methods of the existing dual-band network mainly include parameter adjustment, coverage adjustment and power adjustment, specifically:

The parameter adjustment can be, for example, adjusting the cell reselection offset (CellReselectOffset, CRO), cell reselection hysteresis (Cell Reselect Hysteresis, CRH), penalty time (Penalty Time, PT), minimum received signal level ( RXmin) and other parameters that affect the idle (IDLE) state of the mobile phone, but adjusting the above parameters will affect the cell used by the mobile phone to make calls, resulting in low paging rate and poor quality;

Coverage adjustment is to balance the business of the dual-band network by adjusting the inclination and direction angle of the base transceiver station (BTS), which will make the wireless environment within the adjustment range worse, and may cause abnormal call quality, performance indicators, and test results of the voice network , and requires a lot of manpower and material resources to optimize for a long time, and the workload is relatively large;

The power adjustment has a great impact on the service of the cell, especially the coverage of the cell, and also deteriorates the wireless environment within the adjustment range, requiring a lot of manpower and material resources for long-term optimization.

In a word, adopting the above method may easily lead to deterioration of the wireless environment, cumbersome implementation, low efficiency and long problem-solving cycle (problem finding-problem locating-problem solving).

Example

Fig. 5 is a schematic flow diagram of a method for balancing data services of a dual-frequency co-site and same-coverage cell in a specific embodiment of the present invention. As shown in Fig. 5, the process includes:

Step 501: Obtain information such as the site address, latitude and longitude, frequency band of the cell, and antenna azimuth angle of the base station to which the cell belongs from the basic database of the base station of the operator.

Step 502: According to the acquired information, select dual-frequency co-site and co-coverage cells.

Step 503: Grab the GB signaling data, and count the minimum rate value, maximum rate peak value and average rate value of each dual-frequency co-site and same-coverage cell with a time granularity of 5 minutes.

Taking dual-frequency co-site co-coverage cell 1 as an example, the minimum rate value, maximum rate peak value and average rate value of dual-frequency co-site co-coverage cell 1 obtained in this step are respectively recorded as MinThrput, MaxThrput, and MeaThrpt.

The following uses dual-frequency co-site and same-coverage cell 1 as an example for illustration, and the processing for other dual-frequency co-site and same-coverage cells is similar to that of dual-frequency co-site and same-coverage cell 1.

Step 504: Perform calculation according to MinThrput, MaxThrput, and MeaThrpt to obtain MinConfigure, MaxConfigure, and MeanConfigure.

At present, the EDGE network has been opened in the urban area, and the proportion of MCS9 is relatively high. In this embodiment, when calculating the actual transmission capacity of PDCH in the cell, the theoretical transmission speed of MCS9 is 59.4Kb/S (7.8KB/S). , considering the proportion of MCS9 and the actual loss of the air interface such as no code and error, set a certain proportion (such as 70%) of the empirical weighted value for the laboratory rate of MCS9.

Then, the following calculation results are obtained for dual-frequency co-site and co-coverage cell 1 every 5 minutes:

The minimum number of PDCH configurations MinConfigure=MinThrput/(59.4Kb/S×70%);

The maximum number of PDCH configurations MaxConfigure=MaxThrput/(59.4Kb/S×70%);

The average number of PDCH configurations MeanConfigure=MeaThrpt/(59.4Kb/S×70%);

Step 505: Select the largest M (for example, 24) among the multiple PDCH configuration numbers calculated in step 504 to calculate the average value.

Here, for high user perception scenarios: select the 24 largest MaxConfigures throughout the day, calculate the average value, and record it as MaxConfigure';

For medium user perception scenarios: select the 24 largest MeanConfigures throughout the day, calculate the average value, and record it as MeanConfigure’;

For low user perception scenarios: select the 24 largest MinConfigures throughout the day, calculate the average value, and record it as MinConfigure’.

Step 506: When the dual-frequency co-site co-coverage cell 1 has unbalanced services with the corresponding dual-frequency co-site co-coverage cell, adjust its PDCH configuration.

Here, each user perception level can be adjusted, or only some user perception levels can be adjusted, and the live network configuration is adjusted to the computing configuration. Generally, when the operator's carrier resources are sufficient, it is recommended to use MaxConfigure' corresponding to high user perception.

According to the above description, the scheme of the present invention only changes the configuration information of the cell, does not change the reselection parameters, BTS power and BTS coverage, and has little impact on the network quality, performance and test indicators of the voice network; and, it can be based on Reasonably configure the level of user perception.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.
