Description

一种动态频谱共享系统及方法 技术领域
本发明涉及频语共享技术, 尤其涉及一种在不同无线系统间动态的共享无线频谱资 源的动态频语共享系统及方法。 背景技术
争取更大的带宽, 获得更大的吞吐量是新技术发展的动力之一, 但是随着各种无线 技术逐步向前演进, 频谱的缺乏成为了无线技术发展的瓶颈。
与此同时, 随着新技术的不断发展与成熟, 新系统与老系统的共存, 逐步替换也成 为常态。 在这样的情况下, 如何有效地平滑地利用原有的频谱资源也成为了研究热点。
在研究频谱资源的有效利用方面, 各种无线技术精彩纷呈, 以下分别阐述: 针对载波聚合技术而言, 载波聚合既包含一个频段内的, 也包含频段间的, 通过这 种技术可以有效地把零散的小频谱整合起来,以提供给需要更大带宽的系统使用。然而, 釆用这种载波聚合技术存在的问题是: 必须满足使用的零散频谱本身是空闲的这样的前 提, 而且载波聚合后的干扰问题也是一个急需解决的问题。
针对从寻找空闲频语入手的技术而言, 例如将广播电视模拟转数字后, 原来 700M 内的大量频谱空闲下来, 如何充分利用这些频谱, 同时还不影响已有广播电视业务也是 目前研究的问题。
针对从网络长期发展的角度考虑: 无线技术的进步使得旧系统逐步被替换, 旧系统 所承载的业务也会逐步的迁移到新系统。 在多种无线系统共存的情况下, 因为业务特征 的不同、 用户特征的不同, 在时间、 空间等维度上, 每个系统所使用的频谱负荷差异性 很大,如果可以利用这样的特性来考虑多种无线系统共存情况下的动态频语共享势必能 提高网络资源利用率。 然而要做到根据业务和用户特性进行动态频语共享需要解决很多 问题, 例如: 动态频语规划调整、 网络状态监控及动态频谱迁移判决。 针对动态频语共 享需要解决的这些问题目前并未被付诸实现。 发明内容
