Description

时分复用系统中无线资源的上报和管理方法
技术领域
本发明涉及移动通信系统的无线资源管理特别是时分复用系统中的无线 资源的上报和管理方法。 背景技术
第三代移动通讯系统中, 如时分同步码分多址 (TD-SCDMA) 系统, 无 线资源通常由 RNC来控制的。 RNC (无线网络控制器) 控制无线资源的依据 就是 Node-B (基站)的资源上报情况。 因此 Node-B是否把足够和准确的资源 能力信息上报给 RNC是资源能否正确控制的关键。
Node-B通过 Iub接口向 RNC上报资源通常是通过资源状态指示和资源审 计两种方式进行。
当 Node- B方向本地小区的专用资源发生变化时会通过资源状态指示通知 给 RNC, 如图 1所示。
当 Node-B在收到 RNC的资源审计请求后将审计 Node-B的资源并上报, 使 RNC与 Node-B的资源状态保持一致, 如图 2所示。
现有的资源状态指示和资源审计中包含 Node-B的上行资源能力信息(UL Capacity Credit) 和下行资源能力 (DL or Global Capacity Credit) 信息。
对于单载频系统, 在 TD-SCDMA中 Node-B将上行资源能力信息和下行 资源能力信息模拟成扩频因子 SF=16时的码道资源。假设 Node-B的一个小区 共支持 K个时隙, 其中有 m个上行时隙可用, 有 n个下行时隙可用, 每个上 行时隙可用的码道数为 UlCodeNim^i = 0,Λ ,m), 每个下行时隙可用的码道数为 DlCodeNum」 (j = 0,Λ , n), m禾口 η应该满足:
K = m + n < 7 (1) 则上行资源能力信息和下行资源能力信息分别按下式计算-
UL Capacity Credit = J UlCodeNum; (2)
DL Capacity Credit = (3)
Figure imgf000003_0001
在实际应用中, 当小区建立后, 由于物理资源问题导致某些业务时隙不可 用时, 此时 Node-B的一个小区支持的时隙数 K小于 7。 按照公式 2和 3计算 后的上、 下行资源能力信息通过 Iub接口通知 R C后, 由于上报信息中不包 含各时隙 TS1、 TS2、 TS7的信息, RNC无法根据 Node-B上报的信息 正确获知不可用的时隙, 也不知道每个时隙的资源能力信息, 导致了两者的资 源能力信息不一致, 如图 3所示。
在无线链路建立时, RNC 需要指定 Node-B把无线链路承载在某些时隙 上。 在这种情况下, 由于 R C无法正确获得 Node-B的不可用时隙信息, 当 RNC指定的无线链路承载建立在 Node-B不支持的时隙时, 必然导致无线链路 建立失败。通常一个无线链路同时承载在多个时隙上, 只要其中一个时隙不可 用,无线链路建立就会失败 这种情况下,无线链路建立的成功率会大大降低, 大大地影响系统的接入性能。
目前时分同步码分多址(TD-SCDMA)系统相比宽带码分多址( WCDMA) 系统来说, 容量相对偏低。 为了增加系统容量, 在同一扇区 /小区进行多载频 覆盖无疑是 TD-SCDMA系统增大系统容量的重要手段。
为了减少载频间广播信道的干扰, 提高系统效率, 在多载频的情况下, 仅 在小区 /扇区的一个载频上发送导频和广播信息, 多个频点使用一个共同广播。 如在一个小区 /扇区有 N个载频, 编号分别为 1, 2....... N, 假设载频 1发送导 频和广播信息, 而其他的载频就不发送导频和广播信息。那么载频 1称为主载 频, 其他的载频 2...... N称为辅载频。 主载频和辅载频使用相同的扰码和基本 中间码 (midamble), 公共控制信道相同, 上下行转换点配置一致。 移动终端 通过搜索主载频就可以获取小区的系统信息和其他辅载频的频率配置。
按目前的技术, 在多载频情况下, 基站 (Node-B ) 资源能力信息是以整 个小区的资源能力信息来计算的, 不区分每个载频的资源能力信息。 如图 1 和图 2所示, Node-B通过资源状态指示消息和审计响应消息向无线网络控制 器上报资源时, 消息中包含的是整个小区的资源能力, RNC 无法根据上报信 息获知 Node-B上各载频的资源情况, 导致了两者的资源能力信息不一致, 如 图 3所示。
这样带来一个问题, 一旦辅载频发生故障时, RNC无法知道, 使得 RNC 在分配业务信道的时候还会分配到该辅载频上, 从而导致无线链路建立失败, 极大地影响系统的接入性能。 发明内容
