HSDPA (High Speed Downlink Packet Access: 高速下行分组接入) 的基本工作特 点是无线信道质量好则传送高数据速率, 无线信道质量差则传送低数据速率; 因此可知 只有在信道质量比较好的情况下, 才能体现 HSDPA系统大容量的特点, 才能大幅度提高 系统的容量, 因此我们就可以依据用户所处位置的无线信道质量来选择传输信道的类型 并进行信道迁移, 而本文就是基于信道质量给出的信道类型选择和信道迁移实现方法。

本发明是基于信道质量在 HS- DSCH与 DCH之间进行信道选择与信道迁移的实现方法, 其基本原理如下:(1)通过导频信道的同频测量初步判断用户是否适合在 HS- DSCH上跑数 据;(2)通过用户数据流量需求和 MAC- hs可以提供的带宽, RNC( Radio Network Control : 无线网络控制器)进一步判断用户是否适合在 HS- DSCH上跑数据。
本发明的实现方法中, 当业务初始接入时, 若是第一个业务且该业务允许使用 HS-DSCH,则需要 RNC对无线信道质量进行 IF事件的判决,若满足 1F事件,则设置信道 质量状态为 " IF— Flag状态", 则只能选择接纳在 DCH; 如果不满足 1F事件, 则选择接
纳在 HS- DSCH, 如图 1以及图 3所示。
当业务在保持过程中接入时, 通过导频信道的同频测量初步判断用户是否适合在 HS - DSCH上跑数据, 然后再通过用户数据流量需求和 MAC- hs可提供的带宽, RNC进一步 判断用户是否适合在 HS-DSCH上跑数据。 若该业务允许使用 HS- DSCH, 则只要判断此时 该 UE是否处于 " lF_Flag状态", 若处于, 则该业务只能接纳或迁移到 DCH; 否则可以 接纳或迁移到 HS- DSCH, 如图 1、 图 4和图 5所示。

4、 根据权利要求 3所述的实现方法, 其特征在于, 所述方法具体包括: 当业务正在使用高速分组共享信道时, 所述无线网络控制器对信道质量状态的判决 包括: 如果用户设备的信道质量状态处于质量差的状态, 并且所述高速分组共享信道的 业务需求远远大于高速媒体访问控制协议为其分配的数据流量, 执行所述高速分组共享 信道至专用信道的迁移; 否则, 继续采用高速分组共享信道。
5、根据权利要求 4所述的实现方法, 其特征在于, 所述高速分组共享信道业务的需 求是否远远大于高速媒体访问控制协议为其分配的数据流量通过监测用户面业务量请求 和高速媒体访问控制协议分配的分值来判断。
6、 根据权利要求 3所述的实现方法, 其特征在于, 所述方法具体包括: 当业务正在使用专用信道时, 所述无线网络控制器对信道质量状态的判决包括: 如 果用户业务流量满足迁移到高速分组共享信道的条件, 并且用户信道质量处于质量好的 状态, 执行所述专用信道至高速分组共享信道的迁移; 否则, 继续釆用专用信道。
7、根据权利要求 6所述的实现方法,其特征在于,所述用户业务流量是否满足迁移 到高速分组共享信道的条件通过监测用户面业务量测量来判断, 即业务量缓存达到预定 的门限值时满足迁移到高速分组共享信道的条件。
