Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] figure 1 Two prior art techniques for base station reverse link backup are described. The first prior art uses three radio frequency switches (100, 101 and 102) before the transceivers (103-107), which are respectively responsible for the main set receiving circuit (MRX) and the diversity receiving circuit (DRX) in the transceiver. ) and the backup switching of the forward transmitting circuit (TX). When one of the transceivers (any one of 103-106) breaks down (it may be that the forward transmitting circuit, the reverse receiving circuit or other component circuits fail), by controlling the switching of the three radio frequency switches, select the standby A transceiver (107) replaces a faulty transceiver, thereby avoiding interruption of service. The backup of the second prior art is the radio frequency down-conversion circuit (112-116), and a radio freq...

Abstract

The invention relates to a redundant back-up system and a radio-frequency shifter of base station reverse chain circuit. Wherein, the back-up system utilizes the digital switch and the radio-frequency switch to process the redundant back-up on the digital circuit, digital-analog mixing circuit and the radio-frequency circuit between them, and individually starts or forbids the main reception circuit, the diversity reception circuit and the transmitting circuit of base station to make the system with higher reliability and effectively reduce the service interruption caused by the accidence of circuit of each part. And the radio-frequency shifter is formed by two sub-cards, a group of power diversity devices and a group of quantitative attenuators; while the input and the output of said device are fixed and the inner power diversity devices, the quantitative attenuators and the sub-cards are connected. The back-up shifter can support the programming for a plurality of capacities and the carrier wave sectors of base station, without changing other parts of base station and the interface and connecting line between them.

Description

technical field [0001] The invention relates to a redundant backup of the reverse link of a wireless communication base station, in particular to a redundant backup of the reverse link of a multi-carrier and multi-sector base station. Background technique [0002] With the rapid growth of users of commercial wireless communication systems such as GSM and CDMA, and the increasing variety of wireless communication services, the capacity requirements for wireless base stations are getting higher and higher. Wireless planning is developing in the direction of multi-carriers and multi-sectors. Corresponding Ground, the signal processing circuits in the base station are becoming more and more integrated, each module supports more and more carrier frequencies, and the traffic volume is increasing. Therefore, the failure of a single module may also have a great impact on the service. In this case, it is particularly important to improve the reliability of individual modules and the...
