Method and device for processing fault of channel board, channel board and base station

Abstract

The invention discloses a method and a device for processing fault of an EV-DO channel board, a channel board and a base station. The method comprises the following steps of: establishing a mapping relation between a chip channel of the EV-DO channel board and carrier frequency; monitoring the EV-DO channel board; and when detecting the fault of the EV-DO channel board, automatically removing unavailable carrier frequency caused by the fault of the EV-DO channel board to the chip channel of the available EV-DO channel board. The method, the device, the channel board and the base station adopt the mapping inside the channel and the automatic fault processing of the system, so after the fault is generated, the base station system can immediately perform self-processing on the fault and no-break of services is realized, and the reliability of the EV-DO channel board is improved and optimized.

Description

A channel board fault handling method, device, channel board and base station technical field The invention relates to communication technology, in particular to a channel board fault handling method, device, channel board and base station. Background technique 1xEV-DO (EvolutionDataOnly or EvolutionDataOptimized, evolution data optimization) technology adopts CDMA (CodeDivisionMultipleAccess, code division multiple access) 2000 protocol, the forward link adopts time division multiplexing, the reverse link adopts code division multiple access, and the carrier frequency of each sector The maximum supported rate reaches 3.1MHz. In order to support 1xEV-DO technology, CDMA base stations design and adopt channel boards that support 1xEV-DO technology. The EV-DO carrier frequency of CDMA is configured on the EV-DO logical resource pool of the base station, and the logical resource pool of the base station is composed of physical EV-DO channel boards. An EV-DO channel board u...

Problems solved by technology

However, the current CDMA base station supports 1xEV-DO channel boards, and only supports a single board (short for single channel board) to form an EV-DO resource pool, and does not support multiple EV-DO channel boards to form an EV-DO resource pool. Thus resource sharing between multiple EV-DO channel boards cannot be realized

In addition, even though the EV-DO channel board supports resource pool technology, some channel boards have more than one chip, and the chip resources between these chips cannot be shared

Fig. 1 shows several examples in which EV-DO channel boards cannot realize resource sharing in the prior art

Among them, in Figure 1(a), after the EV-DO channel board 1 fails, the carrier frequency configured on this channel board cannot work, and the cell cannot be established

In Figure 1(b), the EV-DO channel board adopts a dual-chip design, and the resources between the chips cannot be shared. The carrier frequency configured on the chip can only use the resources on the chip. When the chip 1 fails, The carrier frequency configured on faulty chip 1 cannot be started, and the cell cannot be established

In Figure 1(c), there is a one-to-one correspondence between the chip channels on the EV-DO channel board and the carrier frequency. When the channel on the chip fails, the carrier frequency configured on the channel cannot be started, and the cell cannot be established.

In the prior art, when the EV-DO channel board fails, the chip of the EV-DO channel board fails, or the channel of the chip on the EV-DO channel board fails, the corresponding carrier frequency configured cannot be started, which affects the business. Actively discover faults through users and perform manual repairs
