Problems solved by technology

Advances in technology have brought about higher integrated channel processing chips. The subsequent single chip capacity may be more than 8 times that of the current chip, and one chip can support 6-sector configuration. If a single board integrates 4 such chips, and the single board It can only output 6 sectors or 12 sectors, and the channel resources will be redundant. As a result, the existing channel resource pool technology cannot solve the channel allocation problem of multi-chip single boards

Embodiment 1

[0046]For the sake of convenience, take the CDMA base station with a single channel board as an example, the channel processing chip adopts CSM5000, the chip supports 6 sector carrier frequency resources, adopts the base station of the channel full resource pool proposed by the present invention and realizes the base station channel full resource pool The method can easily realize the channel sharing of 6, 12, 18 or 24 sectors, with a single CSM5000 chip as the unit; refer to image 3 , image 3 Schematic diagram of the principle of board-level bottom-level switching scheme to realize 24-sector sharing, each CSM5000 chip is connected to the bottom-level switching module FPGA in star form. CSM5000 chips are divided into 1, 2, 3 or 4 groups according to different application requirements, and the underlying switch module FPGA superimposes the forward data from each CSM5000 chip in the same group according to the grouping of chips, respectively realizing 6, 12, 18 Or a 24-sector...

Embodiment 2

[0051] In the CDMA base station using the CSM5000 chip, each bottom switching unit provides the output capability of 6N sectors. If these bottom switching units are strung together into a daisy chain, and the output of the last bottom layer is taken, 6N sector data can be obtained to realize A 6N sector resource pool, but the single board resource pool cannot support a carrier frequency greater than 6N sectors, and also cannot dynamically isolate the failed underlying switching unit. In order to realize the above two functions, multiple channel boards need to be configured, and the concept of upper-layer switching needs to be introduced. An upper-layer switching module is used. The upper-layer switching module distributes and exchanges forward data from multiple lower-level switching units, and also supports The superposition of data from the bottom switching unit is used to increase channel resources and realize flexible daisy chains between channel boards.

Abstract

The present invention discloses channel all resource pool base station. It contains at least a channel plate having two channel process chip and sublayer switching module. The present invention also discloses a realizing base station channel all resource pool method, which contains sublayer switching module making dynamical grouping each single board channel process chip according to different application requirement, making overlapping and exchanging every chip forward data in same group according to requirement, then through one top level switching module to make exchanging, distributing, and overlapping single board stage channel resource and according to requirement outputting. Said invented base station and method can realize different sector carrier frequency resource pool dynamic scheduling channel resource and dynamical isolating fault chip.

Description

technical field [0001] The invention relates to a technology for realizing a full channel resource pool of a base station in the field of wireless communication, in particular to a base station with a full channel resource pool and a method for realizing the full channel resource pool of the base station. Background technique [0002] In the field of wireless communication, Qualcomm's CSM5000 is commonly used as the channel processing chip of CDMA base stations. CSM5000 supports 6-sector configuration. At the same time, the chip supports cascading. Through chip cascading, a single-board resource pool with 6-sector carrier frequency can be formed. Transceiver use. There are many ways to implement resource pools in the industry, which can be summarized into three technologies: [0003] 1. No exchange direct connection technology [0004] The channel processing chips inside the channel boards are serially connected through the cascading function provided by the chips. The sin...
