Description

technical field [0001] The invention relates to a mobile communication network, in particular to an intelligent repeater which can automatically adjust the parameters of the repeater according to the change of the base station parameters and its parameter automatic adjustment method. Background technique [0002] The repeater is a kind of radio transmission relay equipment that enhances the signal in the process of wireless communication transmission. It is mainly used in areas where the base station signal is too weak. It is used as a relay station. The base station signal is amplified by the repeater, and then transmitted to farther wide area, thus expanding the network coverage. With the development of mobile communication networks and their services, the traffic continues to grow rapidly, and the base stations are transformed from macrocells to microcells to picocells. The number of base stations is increasing, and the frequency reuse rate is getting higher and higher. ...

Problems solved by technology

Since the field strength of the signal received by the repeater equipment changes with the surrounding environment, and the power gain of the repeater is fixed, if the power gain of the repeater is set low, the repeater does not reach the control state. Then the output power of the BCCH carrier of the repeater will change with the field strength of the received signal, resulting in unstable output power; Multi-carrier single power amplifier, when the traffic volume of the base station is small, the number of carrier frequencies amplified by the power amplifier is small, and the power allocated to each carrier is relatively large; when the traffic volume of the base station is high, the number of carrier frequencies amplified by the power amplifier is large, and the power allocated to each carrier The power of each carrier is small, which also causes the output power of the repeater to be unstable.

If the number of carrier frequencies of the base station is large, the single carrier power difference of the repeater station when the base station is busy or idle can reach more than 10dB, which seriously affects the quality of network optimization.

[0005] Although mobile communication operators have a lot of demand for repeaters, due to the above problems, the application of repeaters is greatly restricted, resulting in mobile communication operators gradually reducing the investment in repeaters
