CDMA wireless network optimization processes

[Laramie]

Hi all,

CDMA system is a self-interference system, a user relative to other users is the interference, each cell will be constituted to other cell interference, especially with the carrier frequency of the adjacent areas. I need a comprehensive analysis of the impact location of network quality problems and causes, focusing on troubleshooting in some areas and single-station performance improvement. Can anybody have any idea about how to optimize CDMA wireless network. please suggest. Thanks in advance.

CDMA Wireless network optimization is divided into two phases, one engineering optimization, that is, when the optimization of network construction is mainly the initial network construction and expansion of the early post-optimization, which focuses on the overall performance of the whole network; second, operation and maintenance optimization, is network operations in the process of optimization, the daily optimization, through the integration of OMC, the scene Test, Complaints and other areas of information, a comprehensive analysis of the impact location of network quality problems and causes, focusing on troubleshooting in some areas and single-station performance improvement.

Operation optimization of the main objective is to maintain good network performance indicators, single station troubleshooting and enhance the performance and reduce pilot pollution, expand system capacity to meet the RF performance requirements. Operation optimization of the premise is to make the inspection system data to confirm the same parameter configuration and design. Wan-dimensional optimization are mainly four latitudes, background analysis, customer complaints, road test, as well as call tests. Check and reply.

OMC is a daily back-analysis of actual data collection, statistics and related indicators of the warning messages the base station may occur. Through the OMC statistics, can be a large traffic base station / sector emissions in accordance with the following indicators of the performance of the 20 worst (according to the division of the region may be more or less) a sector / base station: from call failure rate, out If the rate, blocking rate and frame error rate. At the same time traffic is not high for the base station / sector, if the number of days performance of the statistical data show that the poor also need to be tracked and do failure analysis location. In addition, certain base station alarm occurs, such as hardware failures prompted to replace the hardware or overload, etc., but also an important element of the background analysis.

Some users through the dense areas, such as stations, hotels and scenic spots to call the test to ensure that key areas of network performance. Through this four-step process, an integrated positioning problem areas, causes, propose solutions. But in fact, in the daily maintenance of the operation and maintenance, it is important to establish a new station or the relocation of the network state, in this case, it is necessary to monitor the implementation of a number of days until the ensure that the network is functioning correctly. In addition, operation and maintenance in the search of a problem or a primary means of fault location are as follows. Check and reply.

Switching characteristics of the mobile communication technologies is also essential to technology, which can effectively ensure the user's mobile in the process of business continuity, improve the user experience and reduce call drop rates. Therefore, the switch is usually as a special topic for analysis and research. CDMA uses advanced soft-switching and more soft-switching, thereby reducing the call drop rate, and improve the voice quality. Coupled with an advanced CDMA coding and power control, enabling the user's voice quality is clear that these aspects makes the CDMA and GSM voice quality and have greatly improved compared to GPRS. All the best.
