Problems solved by technology

Because for the current CDMA system, the capacity of each sector is less affected by the distribution of system load in the sector, so the distribution of load is not concerned when testing system coverage and capacity. However, the distribution of system load Different distributions affect the capacity levels of beams and sectors, and cannot provide a guarantee for a comprehensive understanding of system performance

Embodiment Construction

[0030] The method for testing the capacity of the fixed beam smart antenna system according to the present invention can be implemented in the following steps. For the flow chart, refer to figure 1 Shown:

[0031] (1) Preparation process:

[0032] Based on the aforementioned coverage test method, the actual coverage of the three beams and the switching area are obtained, and the system noise floor of the cell to be tested is known.

[0033] In the capacity test method, not only the forward and reverse capacity tests are included, the two types of tests also include three items: single-beam capacity test, three-beam load uniform distribution capacity test and three-beam load non-uniform distribution capacity test. Test items differ in the preparation phase:

[0034] The single-beam capacity test requires that the mobile stations participating in the test be distributed sequentially in the coverage area of ​​each beam's main lobe direction. The three-beam load evenly distribu...

Abstract

This invention provides an intelligent aerial base station system capability test method with fixing wave, which includes: the single beam the front reversal capability test, which tests the front reversal capability condition of the distribution of the moving stage in all sorts of the beams' main petal directions, and the multiple ideal condition front reversal capability test, which tests the front reversal capability condition of the distribution of the moving stage in all sorts of the beams' main petal directions, and the multiple non-ideal condition front reversal capability test, which tests the front reversal capability condition of the distribution of the moving stage in each beam of every two beam switch areas, then recording the related test result in group and input the test data from the recording into the front reversal capability compute formula to work out the front reversal limit capability of the system.

Description

technical field [0001] The invention relates to the field of wireless cellular communication, in particular to a capacity testing method of a CDMA (Code Division Multiple Access, frequency division multiple access) base station system using a fixed beam smart antenna. Background technique [0002] In the process of capacity testing for CDMA systems, the current methods are all tested in units of sectors. For sector reverse capacity tests, RSSI (Reverse Signal Strength Indicator) is usually used. The test method is to calculate the limit capacity of the system by measuring the rise of the noise floor at the receiving end of the sector. For the test of the forward capacity of the sector, it is usually based on the method of collecting the effective transmission power of each channel to calculate the system capacity. Limit capacity. For the current CDMA system, the capacity of each sector is less affected by the distribution of the system load in the sector, so the existing te...
