Description

一种卫星带宽的分配、 释放方法， 设备及系统 技术领域
本发明涉及通信领域， 尤其涉及一种卫星带宽的分配、 释放方 法， 设备及系统。 背景技术
在 GSM ( Global System of Mobile communication , 全球移动通 信系统） 网络建设中， 对于一些偏远地区 （例如山区、 荒漠、 岛屿）， BTS( Base Transceiver Station ,基站 )与 BSC( Base Station Controller , 基站控制器 ) 之间的连接一般都采用卫星传输， 即 Abis接口采用卫 星中继。 目前采用的卫星传输系统由 VSAT ( Very Small Aperture Terminal , 极小口径终端） 小站和 HUB (集线器） 主站构成。 在部 署中， 一般是 BTS与卫星 VSAT 小站相连， BSC与卫星 HUB主站 相连。
一方面， 卫星传输带宽租用费用很高， 必须进行有效管理以实 现高效利用。 例如， 当业务需要使用带宽时， 要及时为该业务分配 带宽； 当业务结束后， 应及时将带宽回收。
另一方面， 目前卫星传输一般都利用地球同步轨道卫星， 因此 传输时延较长。 一般数据从 VSAT 通过卫星发送到 HUB , 需要约 300ms的时间， 往返时延约为 600ms。
目前的卫星带宽申请 /译放， 完全由卫星设备 ( VSAT小站 /HUB 主站）通过自身的检测机制完成。 VSAT在一定的统计周期内， 统计 当前使用的带宽， 如果发现带宽不够则向 HUB提出带宽申请。 一般 从 VSAT发出申请到带宽分配完成， 需要 600ms左右的时间。 为了 减少 VSAT 申请带宽过程中对业务的影响， 卫星传输一般都采用了 预留带宽机制， 即 VSAT会比实际使用带宽多申请一些。 释放类似， HUB检测到一定时间内实际使用的带宽比已分配的带宽要小， 则逐 步释放多余的带宽。
VSAT 定期检测当前实际需要的传输带宽， 当发现带宽不足向 HUB主站提出带宽申请后， 需要约 600ms的时间， 才能获得申请的 带宽。 在此期间， 由于带宽不足， 可能会出现业务数据的丟失， 从 而影响业务质量。
另外， 目前采用的带宽预留机制，即 VSAT向 HUB 申请带宽时， 为了减少上述申请时间过长带来的业务数据丟失， 都会比实际测量 值多申请一些带宽。 这些带宽在很多情况下用不上， 是一种资源浪 费。
同样， 当 HUB检测到一定时间段内， 实际使用的卫星带宽比已 分配的带宽低时， 则会逐步的释放未占用的带宽。 但这种方式不能 及时释放带宽资源， 也造成了带宽浪费。 发明内容
