Dynamical collocation method, device and system of CDMA micro base station

Abstract

The invention provides a dynamical collocation method, device and system of a CDMA (Code Division Multiple Access) micro base station, and solves the problem in the prior art that the reverse capacity of a macro base station is very low when the macro base station and a micro base station contain lots of users. The dynamical collocation method comprises the following steps: a base station controller (BSC) is used for receiving thermal noise ROT (Rise-Over-Thermal) overload information transmitted by a micro base station, and the BSC is used for transmitting ROT updating requesting information to the micro base station which is related to the macro base station to decrease ROT threshold value of the micro base station. According to the invention, the ROT overload information which is transmitted by the macro base station transmits ROT updating requesting information to the micro base station to decrease the ROT threshold value of the micro base station, so as to control the data transmitting speed of the users under micro base station sector to be low, that is, the AT (Access Terminal) transmitting power is controlled to be reduced, so as to reduce the inter-user interference, and that is, the effect of micro base station under the macro base station sector on the reverse overload of the macro base station is controlled to guarantee the reverse capacity of the macro base station to reach a normal state.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method, device and system for dynamic configuration of a CDMA miniature base station. Background technique [0002] In the CDMA wireless communication system, with the development of the global economy, high-rise buildings are rising everywhere, hotels, large shopping malls, and supermarkets are constantly being built, and there are more and more entertainment venues. According to the characteristics of people's life and work, office spaces, large residential areas, airports, stations, large commercial areas, exhibition centers, hotels, etc. have become the main activity areas for people. Therefore, ensuring good indoor coverage is the key to improving service levels, developing customers, and increasing operating income. In cities, it is very difficult to cover indoors only by outdoor base station signals, which is often unsatisfactory. It is unrealistic to use t...

Problems solved by technology

In cities, it is very difficult to cover indoors only by outdoor base station signals, which is often unsatisfactory. It is unrealistic to use traditional indoor coverage methods in these places. Solutions for small-scale coverage, enhanced coverage, and blind-filling coverage of micro-base stations are needed, but The macro base station cell involves the coverage of multiple micro base stations. When there are many users, the reverse capacity of the macro base station is very low.

[0003] It can be seen that in the prior art, when there are many users in the macro base station and the micro base station, the reverse capacity of the macro base station is very low.
