Description

说明书 无线资源管理方法及装置
[1] 技术领域
[2] 本发明涉及无线通信技术领域, 尤其涉及一种无线资源管理方法及装置。
[3] 发明背景
[4] 目前, 在移动通信系统中, 基站控制器是主要负责进行无线资源管理的网络实 体, 但是基站控制器进行无线资源管理的很多过程均需要终端 (UE, User Equipment) 上报相关的测量结果信息。
[5] 例如, CDMA系统中特有的切换方式软切换处理过程为:
[6] 当 UE在同频小区间移动吋, 如果发现新的小区信号强度满足一定条件 (通常 指小区导频 Ec/No超过一定门限) , UE就会向基站控制器上报测量结果, 包括新 小区的信号强度值和当前所在小区的信号强度值; 基站控制器根据 UE上报的测 量结果会在该新的小区中为 UE建立新的无线链路, 使 UE能够同吋与新的小区和 当前所在小区等多个小区进行通信, 从而获得更好的合并增益信号。
[7] 再例如, 蜂窝通信系统中常用的切换技术硬切换的处理过程为:
[8] 当 UE在不同小区间移动吋, 如果发现新的小区信号强度满足一定条件, 通常 指小区导频 Ec/No超过一定门限, 或者指小区的接收信号码功率 (RSCP, Receiv ed Signal Code
Power) 超过一定门限, UE就会向基站控制器上报测量结果, 包括新小区的信号 强度值和当前所在小区的信号强度值; 基站控制器根据 UE上报的测量结果就会 在新的小区为 UE建立新的无线链路, 同吋断幵 UE与当前所在小区的无线连接, 从而保证通信业务的正常连续。
[9] 再如在蜂窝通信系统中, 用于确定初始发射功率的常用方法幵环功控的具体处 理过程为:
[10] UE在初始建立无线链路吋, 会向基站控制器上报所测量到的当前所处小区的 信号强度, 通常为 RSCP; 基站控制器根据 UE上报的测量结果来估计路径损耗, 然后确定无线链路建立吋基站下行的初始发射功率。 [11] 由此可见, 上述在基站控制器进行各种无线资源管理吋, 包括软切换、 硬切换 以及开环功控等处理过程中, 都需要基于 UE上报的测量结果来进行。 但是上述 UE的测量结果都是基于单天线方式来测量并上报的, 对于具有多天线能力的 UE 而言, 其具有的每个天线都会分别测量各个小区接收信号的质量情况, 而在现 有技术中, 对于具有多天线能力的 UE如何将每个天线测量得到的测量结果上报 给基站控制器并没有具体的解决方案。

[78] 图 2为本发明实施例 2中的基站控制器的结构示意图;
[79] 图 3为本发明实施例 3中的终端的结构示意图;

[84] 图 8为本发明实施例 14中的基站控制器的结构示意图。
[85] 实施本发明的方式
[86] 出于与传统单天线 UE的兼容性考虑, 使用多天线的 UE (通常具有两个天线, 但本发明实施例的多天线 UE并不局限于双天线) 在向基站控制器上报小区信号 质量的测量结果吋, 可以考虑将多个天线分别测量得到的小区信号质量求取线 性平均值, 将求得的平均值上报给基站控制器, 使基站控制器能够根据多天线 U E上报的测量结果进行无线资源管理。
[87] 这里以正在使用双天线的 UE为例进行说明: 如同样的地理位置, 单天线 UE上 报测量结果 A, 而双天线 UE如果有一个天线测量得到的小区信号质量较差的话 , 则基于求取两个天线测量得到的测量结果的线性平均值上报, 上报的测量结 果 B将会小于 。 但实际上双天线 UE在同样的地理位置, 其测量结果应该比单天 线 UE测量得到的测量结果大才是合理的。 因此可见, 仅仅基于求取各个天线测 量得到的测量结果的线性平均值上报, 会存在上报结果存在误差的问题。 这样 , 基站控制器就不能根据多天线 UE上报的测量结果准确的进行无线资源管理, 可能会出现管理失误的现象。 [88] 例如, 基站控制器仅根据正在使用双天线的 UE上报的测量结果进行无线资源 管理吋, 可能会产生下列问题:
[89] 控制 UE进行软切换吋: 由于 UE上报的活动小区集的信号质量偏差, 因此基站 控制器更倾向于给 UE建立更多的无线链路, 而实际上 UE的接收质量并没有那么 差, 这就造成了网络资源的浪费, 直接导致网络下行容量缩小。
[90] 控制 UE进行硬切换吋: 由于 UE上报的目标小区的信号质量偏差, 因此基站控 制器会推迟进行硬切换, 导致硬切换不及吋, 掉话率上升。
[91] 对 UE进行开环功控吋: 由于 UE上报的小区信号质量偏差, 因此基站控制器就 会将路径损耗估计偏大, 设置的初始发射功率值偏大, 从而导致下行功率浪费
, 网络下行容量缩小。
[92] 因此, 本发明实施例 1提供了一种无线资源管理的方法。 在所述方法中, 首先 接收使用多天线的 UE上报的小区信号质量第一测量结果, 该第一测量结果为 UE 对各天线测量得到的小区信号质量执行合并处理得到的; 然后再根据接收到的 第一测量结果进行各种无线资源管理。
[93] 其中, 合并处理可以是最大比率合并处理或选择性合并处理等。
[94] 此外, UE还可以将对各天线测量得到的小区信号质量求取线性平均值得到的 小区信号质量第二测量结果上报给基站控制器, 以便和已有的标准相适应、 兼 容。
[95] 如图 1所示, 为本发明实施例 1中以具有双天线能力的终端为例的无线资源管理 方法流程示意图。 其中包括:
[96] 步骤 11、 判断终端是否正在使用双天线, 如果是, 进行步骤 12; 否则, 进行步 骤 13。
[97] 步骤 12、 终端上报对其两个天线分别测量得到的小区信号质量执行合并处理得 到的双天线测量结果, 然后进入步骤 14。
[98] 此外, 为了适应 /兼容已有的标准, 终端还可以对该两个天线测量得到的小区 信号质量求取线性平均值, 并将所得到的平均值上报给基站控制器。
[99] 其中, 两天线测量得到的小区信号质量可以基于信号强度或信噪比 (Ec/No) 来表征。 最大比合并处理, 例如, 当以信噪比来表征信号质量吋, 对两个天线 测量得到的信噪比根据最大比率合并后, 所得到的双天线信噪比等于两个天线 分别测量得到的信噪比的线性之和。 选择性合并处理是指在两个天线测量得到 的信号质量中选择一个信号质量较好的作为双天线测量结果。 例如, 若两个天 线测量得到的小区信号信噪比分别为 A和 B, 其中 A>B, 则釆用求取线性平均值 得到的测量结果为 (A + B)/2, 釆用最大比率合并处理得到的双天线测量结果为 A +B, 釆用选择性合并处理得到的双天线测量结果为 A。
[100] 通常情况下釆用合并处理得到的信号质量测量结果要高于釆用求取线性平均值 得到的测量结果。
[101] 步骤 13、 如果终端使用单天线接收, 或者双天线中有一个天线通道损坏, 终端 无法使用双天线接收, 则只上报使用的单天线测量得到的小区信号质量测量结 果, 然后进入步骤 14。
[102] 步骤 14、 基站控制器接收到 UE上报的测量结果, 判断该测量结果中是否包含 釆用合并处理得到的双天线测量结果, 如果是, 进行步骤 15; 否则, 进行步骤 1 6。
[103] 步骤 15、 基站控制器优先使用合并处理得到的双天线测量结果进行无线资源管 理。
[104] 无线资源管理的具体方法与现有技术相同, 在此不再累述。
[105] 步骤 16、 基站控制器使用终端上报的单天线测量结果进行无线资源管理。
[106] 无线资源管理的具体方法与现有技术相同, 因此不再累述。
[107] 上述方案中, 由于基站控制器优先使用合并处理得到的双天线测量结果进行无 线资源管理, 因此终端也可以不发送对两个天线测量得到的小区信号质量求取 的线性值。
[108] 以上仅以双天线为例, 对于其他具有更多天线的终端, 上述方案仍然适用。
[109] 基于上述方法实施例, 本发明实施例 2提供了一种基站控制器, 其结构示意图 如图 2所示, 所述基站控制器可以包括: 接收单元 201和无线资源管理单元 202。
[110] 所述接收单元 201用于接收使用多天线的 UE上报的小区信号质量第一测量结果
, 该第一测量结果为 UE对每个天线测量得到的小区信号质量执行合并处理得到 的结果。 [111] 所述无线资源管理单元 202用于优先根据所述接收单元 101接收到的第一测量结 果进行各种无线资源管理。
[112] 进一步的, 该接收单元 201还可用于接收 UE上报的小区信号质量第二测量结果
, 该第二测量结果为 UE对每个天线测量得到的小区信号质量求取的线性平均值
。 在这种情况下, 所述无线资源管理单元 202优先釆用经过合并处理后的第一测 量结果进行无线资源管理。
[113] 由于无线资源管理单元 202优先使用接收单元 201接收到的第一测量结果进行无 线资源管理, 因此该基站控制器也可以不接收釆用求取线性平均值得到的第二 测量结果。
[114] 相应的, 本发明实施例 3还提供了一种终端, 该终端使用多个天线用于收发无 线信号。 其结构示意图如图 3所示, 包括: 第一测量结果生成单元 310和上报单 元 320。
[115] 所述第一测量结果生成单元 310用于对每个天线测量得到的小区信号质量执行 合并处理, 生成小区信号质量第一测量结果。 其中, 所述合并处理可以是最大 比率合并处理或选择性合并处理
[116] 所述上报单元 320用于将所述第一测量结果生成单元 310生成的小区信号质量第 一测量结果, 上报给基站控制器。
[117] 进一步可选地, 该终端还包括第二测量结果生成单元 330。
[118] 所述第二测量结果生成单元 330用于对每个天线测量得到的小区信号质量求取 线性平均值, 生成小区信号质量第二测量结果。
[119] 同吋, 所述上报单元 320还可以用于将第二测量结果生成单元 330生成的小区信 号质量第二测量结果, 上报给基站控制器。
[120] 上述实施例提出的方案多应用于 CDMA、 FDMA和 OFDM无线通信系统中。 这 些方案中, 针对多天线终端的特殊性, 终端上报其对各天线测得的结果进行合 并处理后得到的多天线测量结果, 从而使基站控制器根据该经处理后的测量结 果能够准确的进行各种无线资源管理, 减少了网络资源浪费, 节约了网络下行
[121] 另外, 本发明实施例 4还提出了一种无线资源管理方法, 在所述方法中: 使用 多天线的终端对每个天线测量得到的小区信号质量执行合并处理, 并根据合并 处理后得到的测量结果进行无线资源管理。
[122] 其中, 所述合并处理为可最大比率合并处理或选择性合并处理。 具体实施方式 与前述实施例中的合并处理方式类似, 此处不再赞述。
[123] 具体的无线资源管理方法也与现有技术相同, 此处不再赞述。
[124] 相应地, 基于上述实施例中的方法, 本发明实施例 5还提出了一种终端, 包括
: 合并处理单元和无线资源管理单元。
[125] 合并处理单元, 用于对每个天线测量得到的小区信号质量执行合并处理; [126] 无线资源管理单元, 用于根据合并处理单元合并处理得到的测量结果进行无线 资源管理。
[127] 上述本发明实施例所提出的方案多应用于 CDMA、 FDMA和 OFDM无线通信系 统中。 该方案使具有多天线能力的终端能够准确的进行各种无线资源管理, 减 少了网络资源浪费, 节约了网络下行容量。
[128] 本发明实施例 6提出了一种无线资源管理方法.该方法中, 首先接收具有多天线 能力的 UE上报的多天线能力信息以及小区信号质量测量结果, 该测量结果为 UE 对每个天线测量得到的小区信号质量求取的线性平均值; 然后根据接收到的多 天线能力信息, , 按照高于接收到的测量结果进行无线资源管理。 以下结合附 图并举例进一步详细说明。
[129] 如图 4所示, 为以具有双天线能力的终端为例的无线资源管理方法流程示意图
[130] 步骤 41、 终端上报其双天线能力信息。
[131] 比如, 终端可在建立无线链路吋,向基站控制器上报其双天线能力信息。 如果是 具有双天线能力的终端, 在其不使用双天线能力或者发现双天线中有一个天线 通道损坏, 无法使用双天线测量小区信号质量吋, 则与单天线终端接收信号相 同, 这种情况下, 终端需上报其使用单天线的信息给基站控制器。
[132] 步骤 42、 基站控制器判断终端是否使用双天线, 若是, 进行步骤 43; 否则, 基 站控制器釆用终端上报的单天线测量的小区信号质量测量结果进行无线资源管 理。 [133] 步骤 43、 基站控制器提升该终端上报的测量结果。
[134] 其中, 终端上报的测量结构可以是釆用求取线性平均值的方法得到。 求取线性 平均值的方法如前所述, 此处不再重复。
[135] 提升测量结果的方法包括但不限于如下三种方式:
[136] 方式 1、 将终端上报的测量结果乘以一个大于 1的系数, 例如 1.1。 该系数可以根 据终端上报的测量结果所在区间确定, 例如当 Ec/No位于 -8dB到 -10dB吋可乘以 1.
1, Ec/No位于 -10dB到 -12dB吋可乘以 1.2等。 该系数可以是由终端或者基站控制 器预先设置的一合理的值。
[137] 方式 2、 将终端上报的测量结果增加一预定增量值, 例如 0.5dB等。 该增量值可 以根据终端上报的测量结果所在区间确定, 例如当 Ec/No位于 -8dB到 -10dB吋加 上 0.4dB, Ec/No位于 -10dB到 -12dB吋加上 0.6等。 该增量可以是由终端或者基站 控制器预先设置的一合理的值。
[138] 方式 3、 基于接收到的测量结果, 在预先设置的接收测量结果与提升测量结果 的映射关系中, 査找到对应的提升测量结果。 例如当接收到的测量结果 Ec/No为-
9dB吋, 对应的提升测量结果 Ec/No为 -8.6dB; 当接收到的测量结果 Ec/No为 -8dB 吋, 对应的提升测量结果 Ec/No为 -7.7dB等。
[139] 步骤 44、 基站控制器根据提升后的高于接收到的测量结果进行无线资源管理, 无线资源管理方法与现有技术相同, 因此不再累述。

[144] 其中所述无线资源管理单元 503对所接收到的测量结果进行提升处理的方法可 如前述方法实施例中介绍的各种处理方法。
[145] 另外, 本发明实施例 8还提出一种终端, 该终端使用多个天线用于收发无线信 号。 其结构示意图如图 6所示, 包括: 能力信息上报单元 610、 测量结果生成单 元 620和测量结果上报单元 630。

[148] 所述测量结果上报单元 630用于将测量结果生成单元 620生成的测量结果上报给 基站控制器, 所述基站控制器根据其上报的测量结果准确的进行各种无线资源 管理。
[149] 上述本发明实施例所提出的各方案多应用于 CDMA、 FDMA和 OFDM无线通信 系统中。 该方案提出多天线终端上报其多天线能力信息以及釆用求取线性平均 值得到的多天线测量结果, 由于釆用求取线性平均值的方法得到的测量结果偏 差, 基站控制器对该上报的测量结果进行提升并根据提升后的高于接收到的多 天线测量结果进行无线资源管理, 从而能够准确的进行各种无线资源管理, 减 少了网络资源浪费, 节约了网络下行容量。
[150] 上述实施例 7等的技术方案中, 是由基站控制器对终端上报的釆用求取线性平 均值的方法得到的测量结果进行提升处理的。 在实际应用本发明实施例的过程 中, 也可以由终端来完成, 并由终端将经该提升处理后的测量结果上报给所述 基站控制器。
[151] 基于此, 提出本发明实施例 9的方案。 在该方案中, 基站控制器接收使用多天 线的终端上报的小区信号质量第一测量结果, 其中, 该第一测量结果为终端对 每个天线测量得到的小区信号质量求取线性平均值, 并对该求取的线性平均值 进行提升处理后得到的结果; 所述基站控制器按照所述接收到的第一测量结果 进行无线资源管理。
[152] 为了与已有标准相适应, 基站控制器还可以接收终端上报的第二测量结果, 所 述第二测量结果为所述终端对每个天线测量得到的小区信号质量求取的线性平 均值, 即与前述第一测量结果比, 终端对该第二测量结果没有进过提升处理。
[153] 其中, 该方案中终端对求取的线性平均值进行提升处理的方法与前述基站控制 器对其进行提升的方法相同, 此处不再赞述。

[157] 为与现有的标准适应、 兼容, 进一步可选地, 所述的终端还可以包括: 第二测 量结果生成单元, 用于对所使用的每个天线测量得到的小区信号质量求取线性 平均值, 生成小区信号质量第二测量结果。 相应的, 所述测量结果上报单元还 可用于将所述第二测量结果生成单元生成的第二测量结果上报给基站控制器。
[158] 上述实施例的方案可应用于 CDMA、 FDMA和 OFDM无线通信系统中。 该方案 中, 通过对使用多天线的终端的各天线测得的小区信号质量求取的线性平均值 进一步进行提升处理, 从而使基站控制器可根据提升后的结果更准确的进行各 种无线资源管理, 从而减少了网络资源浪费, 节约了网络下行容量。
[159] 本发明实施例 11还提出一种无线资源管理方法, 在该方法中, 使用多天线的终 端对每个天线测量得到的小区信号质量求取线性平均值, 并对求取的线性平均 值进行提升; 并按照提升后的结果进行无线资源管理。
[160] 其中, 使用多天线的终端对求取的线性平均值进行提升的方法与实施例 7中基 站控制器对线性平均值进行提升的方法相同, 此处不在赞述。
[161] 相应地, 本发明实施例 12还提出一种终端, 该终端使用多个天线用于收发无线 信号。 包括: 测量结果处理单元、 提升单元和无线资源管理单元。
[162] 所述测量结果处理单元用于对每个天线测量得到的小区信号质量进行处理, 其 中该处理可为对各天线测量得到的小区信号质量求取线性平均值。

[165] 上述实施例的方案可应用于 CDMA、 FDMA和 OFDM无线通信系统中。 该方案 使具有多天线能力的终端按照提升处理后的高于原测量结果的结果进行无线资 源管理, 从而能够准确的进行各种无线资源管理, 从而减少了网络资源浪费, 节约了网络下行容量。
[166] 本发明实施例 13还提出一种无线资源管理方法, 包括: 接收具有多天线能力的 终端上报的多天线能力信息以及小区信号质量测量结果, 该测量结果为终端对 每个天线测量得到的小区信号质量求取的线性平均值; 然后再根据接收到的多 天线能力信息, 在判断终端正在使用多天线吋, 调整对应的无线资源管理参数 并基于调整后的无线资源管理参数和接收到的测量结果进行无线资源管理。
[167] 如图 7所示, 为以具有双天线能力的终端为例吋, 体现上述实施例 13中无线资 源管理方法的流程示意图, 包括:
[168] 步骤 71、 终端上报其双天线能力信息。
[169] 比如, 在建立无线链路吋终端向基站控制器上报其双天线能力信息。 如果是具 有双天线能力的终端, 在其不使用双天线或者发现双天线中有一个天线通道损 坏, 无法使用双天线测量小区信号质量吋, 则与单天线终端接收信号相同, 这 种情况下, 终端需上报其使用单天线能力的信息给基站控制器。
[170] 步骤 72、 基站控制器根据终端上报的能力信息, 判断终端是否使用双天线, 若 是, 进行步骤 73; 否则, 基站控制器釆用终端上报的单天线测量的小区信号质 量的测量结果进行无线资源管理。
[171] 步骤 73、 基站控制器调整其对应的无线资源管理参数。
[172] 其中的调整的方法可以是但不限于以下三种:
[173] 1、 若无线资源管理为控制终端进行软切换吋, 调整对应的无线资源管理参数 是指: 将软切换的活动小区集数量减少, 例如将活动小区集数量从 3减为 2。 具 体减少的数量可以根据运营商链路预算 (考虑软切换开销) 和网络优化过程来 确定, 本发明实施例不做限定。 [174] 2、 若无线资源管理为控制终端进行硬切换吋, 调整对应的无线资源管理参数 是指: 将硬切换的小区质量门限阈值降低, 例如将硬切换门限阈值降低 ldB。 具 体降低的幅度由运营商链路预算和网络优化过程来确定, 本发明实施例不做限 定。
[175] 3、 若无线资源管理为对终端进行开环功控吋, 调整对应无线资源管理参数是 指: 将基站的初始发射功率降低, 例如将初始发射功率降低 0.5dB, 具体降低的 幅度由运营商链路预算和网络优化过程来确定, 本发明实施例不做限定。
[176] 步骤 74、 基站控制器根据调整后的无线资源管理参数和接收到的釆用求取线性 平均值的方法得到的测量结果进行无线资源管理。
[177] 相应地, 本发明实施例 14还提出了一种基站控制器, 其结构示意图如图 8所示 , 包括: 能力信息接收单元 801、 测量结果接收单元 802、 参数调整单元 803和无 线资源管理单元 804。

[182] 上述本发明实施例所提出的方案对于软切换可应用于 CDMA无线通信系统, 对 于硬切换和开环功控多应用于 CDMA、 FDMA和 OFDM无线通信系统中。 这些方 案中, 多天线终端上报其多天线能力信息以及釆用求取线性平均值得到的多天 线测量结果。 由于釆用求取线性平均值的方法得到的测量结果偏差, 因而基站 控制器对资源管理参数调整并根据调整后的资源管理参数以及终端上报的测量 结果进行无线资源管理, 从而使基站控制器能够准确的进行各种无线资源管理 , 减少了网络资源浪费, 节约了网络下行容量。
[183] 本发明实施例 15还提供了一种无线资源管理方法, 该方法中, 使用多天线的终 端对其各天线测量得到的小区信号质量求取线性平均值; 终端接收基站控制器 下发的、 经调整后的用于指示所述终端进行无线资源管理的无线资源管理参数 ; 并根据接收到的无线资源管理参数和求取得到的线性平均值进行无线资源管 理。

[193] 其中, 参数调整单元将下发给单天线终端的小区选择和重选参数降低, 作为用 以指示所述终端进行小区选择和重选的无线资源管理参数。
[194] 上述本发明实施例所提出的方案多应用于 CDMA、 FDMA和 OFDM无线通信系 统中。 该方案通过调整用于指示使用多天线的终端进行无线资源管理的无线资 源管理参数, 使具有多天线能力的终端能够准确的进行各种无线资源管理, 减 少了网络资源浪费, 节约了网络下行容量。 [195] 上述的各方法、 装置 (终端, 基站控制器) 实施例中, 基站控制器在 2G通信系 统中称为 BSC (Base Station Controller) , 在 3G通信系统中为 RNC (Radio Network
Controller) 。 同吋, 基站控制器以及终端中所包括的各个单元只是按照功能逻 辑进行划分的, 但并不局限于上述的划分, 只要能够实现相应的功能即可。 在 具体实现过程中, 比如可由其中的射频模块等来完成各个单元的功能, 另外, 各功能单元的具体名称也只是为了便于相互区分, 并不用于限制本发明的保护 范围。
[196] 本领域普通技术人员可以理解, 上述各实施例方法中的全部或部分步骤可以通 过程序来指令相关的硬件完成的, 比如可以通过在计算机上运行程序来完成。 所述的程序可以存储于一种计算机可读存储介质中, 该存储介质可以是只读存 储器, 磁盘或光盘等。
[197] 综上所述, 本发明实施例针对多天线终端的特殊性, 对各天线测量得到的小区 信号质量进行一定的处理 (比如, 合并处理, 或者求取的线性平均值, 或者对 求取的线性平均值进一步进行提升, 或者进一步对无线资源管理参数进行调整 等) , 从而可是根据该测量结果准确的进行各种无线资源控制, 从而减少了网 络资源浪费, 节约了网络下行容量。
[198] 显然, 本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的 精神和范围。 这样, 倘若本发明的这些修改和变型属于本发明权利要求及其等 同技术的范围之内, 则本发明也意图包含这些改动和变型在内。
