Problems solved by technology

However, when the anti-blocking index of the base transceiver station is improved while other indicators remain unchanged, the design dynamic range of the base transceiver station is increased, requiring higher technology and accessories, thereby increasing the production cost of the equipment

Embodiment Construction

[0026] At first, explain the overall process of the present invention:

[0027] 1) After selecting the base station address, determine the installation height, direction and inclination angle of the antenna of the base station transceiver;

[0028] 2) Obtain the minimum path loss MCL of the receiving antenna of the mobile device and the minimum probability pl of the occurrence of the minimum path loss through measurement or calculation; and the occurrence probability of the minimum path loss in the coverage area of ​​the transceiver of the base station shall not be lower than pl;

[0029] Among them, pl is related to the network planning strategy. The smaller the value, the lower the blocking probability of the cell, but at the same time it will reduce the coverage of the cell. Therefore, it needs to be configured according to the link budget strategy or system simulation results.

[0030] And 0

Abstract

The present invention provides a programming method of a wireless network, including: defining a new Blocking_Target of the base station transreceiver according to respective isolations; defining the correspondingly new RS_Target of the base station transreceiver according to the new Blocking_Target of the base station transreceiver. The programming method of the wireless network provides different Blocking_Targets and RS_Targets according to the different isolations of base stations, effectively avoiding the blocking condition easily produced by base stations which isolations are not enough caused by the same blocking index of the whole network, improving the covering ability for some base stations having better isolations at the same time. The method of the invention flexibly processes network programming, sufficiently improving the use efficiency of the limited hardware resources.

Description

technical field [0001] The present invention relates to network planning, in particular to a wireless network planning method. Background technique [0002] Any base transceiver station has a certain receiving dynamic range. When the receiving power exceeds the maximum power level allowed by the receiving dynamics, it will cause the base transceiver station to be saturated and blocked, which is called blocking interference. Blocking will cause the base transceiver station to fail to work normally. work, long-term blocking may also cause permanent performance degradation of the base transceiver station, so we must try our best to avoid this situation; signal strength. The blocking index and reference sensitivity of a base transceiver station in a wireless communication system can be regarded as the upper and lower limits of the dynamic range of the base transceiver station, and describe the performance of the base transceiver station. The larger the dynamic range, the bette...
