Description
Technical field
The present invention relates to wireless communication technology field, refer in particular to a kind of information management system, apparatus and method of smart antenna.
Background technology
In existing wireless communication technology, smart antenna has obtained using widely.When using smart antenna, generally all need corresponding antenna weighting parameter to be set for each smart antenna.Yet, existing smart antenna of a great variety, for example, vertical polarized antenna is arranged, dual polarized antenna, electrical tilt antenna, (frequency range is generally 1880～1920MHz and 2010～2025MHz) to narrow-band antenna, wideband section antenna (frequency range is generally 1880-2400MHz) and the built-in pair of two-in-one antenna of terrace multiple antennas such as (built-in frequency range are two antenna surfaces of 1880～2025MHz and 2010～2400MHz), and the configuration of the initial weight parameter of the antenna that different manufacturers is produced is also also inequality, therefore, when carrying out the outfield networking, might use the dissimilar antenna of same manufacturer production or even the dissimilar antenna that different manufacturers is produced, for example, in TD SDMA in the prior art (TD-SCDMA) system, 28 kinds of different types of smart antennas have been used by 7 tame manufacturer production.Because the type of employed smart antenna is a lot of and manufacturer is also different in the system, therefore the information that present background net management or baseband processing unit (BBU) all are difficult to obtain in time employed various smart antennas, thereby can't effectively manage smart antenna, be easy to generate the phenomenon of the weighting parameter of error configurations smart antenna, thereby the performance of smart antenna is produced adverse influence.In addition, in actual application environment, a batch phenomenon of the failure might appear in employed smart antenna, and the position of the smart antenna that breaks down generally relatively disperses, and adds the supply of material, other reason such as the change of exchanging goods, construct, thereby is easy to generate serious AM/BAM information mismatch phenomenon, be difficult to search the smart antenna that breaks down, make that day yarn batches tracking property is poor, network performance is difficult to be protected, and all will cause unnecessary loss to network and antenna producer.
In the prior art, generally alleviate the problem of above-mentioned appearance by two kinds of methods as described below.
First method is: each manufacturer confirms to concentrate somewhere producer, the type of the antenna of the supply of material by artificial mode, and, parameters such as antenna weighting parameter, antenna type manually are entered among the BBU by background net management or LMT Local Maintenance Terminal according to the antenna parameter that each antenna producer is provided.When using this mode,, then need to confirm one by one the producer of the smart antenna of each actual use, so that correctly dispose various parameters such as antenna weights to the scene if used the smart antenna of a plurality of manufacturer production in same area.The process of above-mentioned affirmation is more loaded down with trivial details, and workload is big and must be by manually finishing, and, after the smart antenna of indivedual websites is replaced, cause confusion easily.Therefore, when the operation of actual engineering, uses above-mentioned method to be difficult to accomplish accurate, and the realization difficulty is very big.
Second method is: by management data platform of network operation organizational maintenance, parameters such as the antenna weights of each smart antenna of unified management are also determined corresponding standard, and the antenna type and the corresponding parameters such as antenna weights of each producer is provided.Background net management can obtain the up-to-date antenna type and the parameter information tabulation of different manufacturers from above-mentioned management data platform, and is handed down to BBU, thus parameters such as typing antenna weights.When using said method, though can unified management, maintenance and upgrade different manufacturers, dissimilar antenna and the isoparametric corresponding relation of its antenna weights, but still need confirm the producer and the type of on-the-spot actual employed smart antenna by artificial mode, could the parameters such as antenna weights of this smart antenna be disposed exactly, workload is still big and must be by manually finishing.
Hence one can see that, in above-mentioned prior art in employed two kinds of methods, because background net management and BBU all can not realize obtaining automatically information such as the type, parameter of each smart antenna of actual use, and can only confirm above-mentioned aerial information by artificial mode, the accuracy of the aerial information that therefore very difficult assurance is obtained, and workload is also very big.And, website in the system that uses along with reality increases gradually, the increase and the passing of the time of arranging net of the difficulty of increase, antenna maintenance and the replacing of the increase of antenna supply of material producer number, antenna type, the information of accurately confirming the smart antenna of each website by the manual type complexity and difficult more that will become.
