Problems solved by technology

Because for the current CDMA system, the coverage 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. However, different distributions of system load , but affects the coverage of beams and sectors, and cannot provide a guarantee for a comprehensive understanding of system performance

Embodiment Construction

[0029] The coverage testing method of the fixed-beam smart antenna system of the present invention can be specifically implemented according to the following steps, and the flow chart is shown in Figure 1:

[0030] (1) Preparation process:

[0031] Prepare various test equipment and software, unify the drive tester, test mobile station, and base station clock into GPS (Global Position System, Global Positioning System) time, connect the test equipment and start the relevant test software, and determine the test route at the same time. Traversing the expected coverage of each beam as much as possible, here we take three beams as an example.

[0032] The test of forward traffic channel coverage and reverse traffic channel coverage includes three items: no-load coverage test, uniform distribution half-load coverage test and non-uniform distribution half-load coverage test. All three items require the base station to be set to full-rate Markov (Markov) call mode, the test mobile ...

Abstract

This invention relates to the wireless beehive communication field, which provides a covering test method for the aptitude antenna base station system with the fixing wave hank, and the method adds the test tache of the different system load distributing affecting the covering on the base of the present testing method, which measures the covering condition of the front reversal service channel under the situation of the empty covering, uniform half-loaded covering and non-uniform half-loaded covering, and it outputs the tested result as the form of the graph. This invention provides a safeguard for comprehending the capability of the system completely.

Description

technical field [0001] The invention relates to the field of wireless cellular communication, in particular to a coverage test method using a fixed beam intelligent antenna CDMA (Code Division Multiple Access, frequency division multiple access) base station system. Background technique [0002] In the coverage test process aimed at the CDMA system, the current method is to test with the sector as the unit. For the coverage of the sector, the test equipment is usually used to measure the total received power value in the predetermined coverage area of ​​the target sector, and the coverage boundary is judged by whether the total received power value is lower than the minimum receiving threshold. For the current CDMA system, the coverage of each sector is less affected by the distribution of the system load in the sector, so the existing test methods do not care about the distribution of the load when testing the system coverage. [0003] With the development of mobile commun...
