图 1 为本发明天线接收模式的配置处理方法实施例一的流程图, 如图 1 所示, 本实施例提供了一种天线接收模式的配置处理方法, 具体釆用静态配 置方法对用户的天线接收模式进行配置, 具体可以包括如下步骤:
步骤 101 , 在用户在基站申请建立或增加无线链路时, 基站控制器根据 所述用户的资源分配信息确定所述用户的天线接收模式。
在用户在基站下的某小区准备建立或增加无线链路时, 用户向基站发出 相应的无线链路申请,基站控制器可以在通过基站获取到该无线链路申请后, 根据用户的资源分配信息来确定该用户的天线接收模式, 即本实施例中基站 控制器以用户为粒度对天线接收模式进行配置。
具体地, 本实施例中的用户的资源分配信息可以包括以下信息中的一种 或多种的组合: 用户业务类型、 用户信道质量、 用户优先级信息、 剩余可用 基带处理资源和许可(l i cense )信道单元(Channe l Element ; 以下简称: CE )数目。 则本实施例中的上述步骤可以具体为基站控制器根据用户的上述 资源分配信息中的一种或者几种的组合来决定用户应使用的天线接收模式。 具体地, 在本实施例中, 在用户在基站申请建立或增加无线链路时, 基站控 制器可以根据用户业务类型来确定用户的天线接收模式, 此处的用户业务类 型可以根据用户所使用业务的业务质量要求等分为语音用户和数据用户, 如 果用户为语音用户, 由于其对业务质量要求较高, 可以将这种类型的用户的 天线接收模式统一配置为第一天线接收模式, 本实施例中的第一天线接收模 式可以具体为 4天线接收模式, 后续的第二天线接收模式可以具体为 2天线 接收模式, 不再赘述。 在用户在基站申请建立或增加无线链路时, 基站控制 器还可以根据用户信道质量来确定用户的天线接收模式, 如果用户的信道质 量较低时, 可以优先将其天线接收模式统一配置为第一天线接收模式。 在用 户在基站申请建立或增加无线链路时, 基站控制器还可以根据用户的优先级 信息来确定用户的天线接收模式, 例如可以将金牌用户的天线接收模式优先 配置为第一天线接收模式。 在用户在基站申请建立或增加无线链路时, 基站 控制器还可以根据当前剩余可用基带处理资源或许可 CE 数目来确定用户的 天线接收模式。 在本实施例中, 在用户在基站申请建立或增加无线链路时, 基站控制器还可以根据用户的业务类型、 用户的信道质量、 用户的优先级信 息、 剩余可用基带处理资源或许可 CE数目来综合决定用户的天线接收模式。
步骤 102 , 基站控制器按照所述用户的天线接收模式对应的 CE消耗准则 进行用户准入处理。
本实施例为静态配置方法, 在通过上述步骤确定用户后续统一使用的天 线接收模式后, 基站控制器按照该天线接收模式对应的 CE 消耗准则对该用 户进行准入处理, 并且基站控制器通知基站该用户应使用的天线接收模式。 基站在接收到基站控制器的通知消息后, 为该用户分配相应的天线基带处理 资源, 进一步地, 在该用户的建立或增加的无线链路的整个生命周期内维持 使用这些天线基带处理资源。
本实施例提供了一种天线接收模式的配置方法, 通过在用户在基站申请 建立或增加无线链路时, 基站控制器根据用户的资源分配信息确定用户的天 线接收模式, 并按照该天线接收模式对应的 CE消耗准则对用户进行准入处 理; 本实施例由于以用户为粒度来配置同一基站或小区内不同用户的天线接 收模式, 因此可以分别满足各用户的上行接收性能, 同时, 由于本实施例以 用户的具体资源分配信息为依据进行配置, 不会造成盲目配置所带来的不必 要的资源浪费, 节省了运营商的硬件及基带处理资源的投资。
图 2 为本发明天线接收模式的配置处理方法实施例二的流程图, 如图 2 所示, 本实施例提供了一种天线接收模式的配置处理方法, 具体为静态配置 方法, 可以具体包括如下步骤:
步骤 201 , 在用户在基站申请建立或增加无线链路时, 基站控制器判断 该用户是否为语音用户, 如果是, 则执行步骤 205 , 否则执行步骤 202。 在本实施例中, 在基站控制器获知用户在基站申请建立或增加无线链路 时, 先判断用户是否为语音用户。 如果该用户为语音用户, 由于语音用户所 消耗的 CE 数目较少, 且移动性较大, 对业务质量要求也较高, 则执行步骤 205 , 直接将该用户的天线接收模式配置为第一天线接收模式, 即 4天线接收 模式。 如果该用户为数据业务, 则可以再综合考虑该用户的其他资源分配信 息来确定该用户的天线接收模式, 继续执行后续步骤 202。
步骤 202 , 基站控制器判断该用户的信道质量是否小于预设的信道质量 门限值, 如果是, 则执行步骤 205 , 否则执行步骤 203。
在基站控制器判断该用户为数据用户时, 继续判断该用户的信道质量是 否小于预设的信道质量门限值。 具体地, 在获取用户的信道质量时, 可以根 据用户的状态类型来通过不同的方式获取, 如果该用户为新接入用户时, 则 基站控制器可以根据用户接入时上报的信号干扰比(Ec/ Io )、 接收信号码功 率 ( Rece i ved S i gna l Code Power ; 以下简称: RSCP )等信息来获取该用户 所处的环境信息, 具体为无线环境信息; 如果该用户为切换用户, 则基站控 制器可以根据用户在测量报告中上报的 Ec/ Io、 RSCP等质量来说去该用户所 处的无线环境信息;再才艮据该无线环境信息获取到该用户的具体的信道质量。 本步骤为判断该用户的信道质量是否低于预设的信道质量门限值, 如果是, 表明该用户的信道质量较差, 则执行步骤 205 , 将该用户的天线接收模式配 置为第一天线接收模式, 使得该用户可以优先使用 4天线接收模式对应的天 线基带处理资源。如果该用户的信道质量大于或等于预设的信道质量门限值, 则可以再综合考虑该用户的其他资源分配信息来确定该用户的天线接收模 式, 继续执行后续步骤 203。 值, 如果是, 则执行步骤 205 , 否则执行步骤 204。
在基站控制器判断该用户为数据用户, 且该用户的信道质量大于或等于 限值, 如果是, 则执行步骤 205 , 可以优先将该用户的天线接收模式确定为 第一天线接收模式。 若该用户的优先级小于预设的优先级门限值时, 继续执 行后续步骤 204 , 再综合考虑该用户的其他资源分配信息来确定该用户的天 线接收模式。
步骤 204 , 基站控制器判断当前剩余可用基带处理资源或许可 CE数目是 否大于预设的数目门限值, 如果是, 则执行步骤 205 , 否则执行步骤 206。
在基站控制器判断该用户为数据用户, 该用户的信道质量大于或等于预 设的信道质量门限时, 且该用户的优先级小于预设的优先级门限值时, 继续 判断当前剩余可用基带处理资源或许可 CE数目是否大于预设的数目门限值, 如果是, 则表明当前资源还比较充裕, 执行步骤 205 , 将该用户的天线接收 模式确定为第一天线接收模式。若当前剩余可用基带处理资源或许可 CE数目 小于预设的数目门限值时, 则执行步骤 206 , 将该用户的天线接收模式确定 为第二天线接收模式, 为之后可能的需求预留资源。
在本实施例中, 在根据用户资源信息配置天线接收模式时, 如果只考虑 用户业务类型、 用户信道质量、 用户优先级信息、 剩余可用基带处理资源和 l i cense CE数目中的某几个因素时, 可以按照上述顺序来依次判定, 例如 £ 设只考虑用户业务类型、 用户优先级信息和 l icense CE数目时, 则优先级顺 序从先到后依次为用户业务类型、 用户优先级信息和 l i cense CE数目。
进一步地, 在本实施例中, 若基站控制器发现当前剩余可用基带处理资 源或者 license CE数目小于预设的数目门限值, 且当后续出现符合使用 4天 线接收模式的判断条件的新建无线链路时, 说明当前的资源已经受限, 基站 控制器对基站的资源进行打点, 作为扩容的依据之一。
步骤 205 , 基站控制器将用户的天线接收模式确定为第一天线接收模式, 并结束本流程。
若用户的业务类型为语音用户时, 或者若用户的信道质量小于预设的信 道质量门限值时, 或者若用户的优先级大于预设的优先级门限值时, 或者若 当前剩余可用基带处理资源或许可 CE数目大于预设的数目门限值时,将用户 的天线接收模式确定为第一天线接收模式, 即 4天线接收模式。
步骤 206 , 基站控制器将用户的天线接收模式确定为第二天线接收模式。 若用户的业务类型为数据用户, 用户的信道质量大于或等于信道质量门 限值, 用户的优先级小于或等于优先级门限值, 且当前剩余可用基带处理资 源或许可 CE数目小于或等于预设的数目门限值时,将用户的天线接收模式确 定为第二天线接收模式, 即 2天线接收模式。
本实施例提供了一种天线接收模式的配置方法, 通过在用户在基站申请 建立或增加无线链路时, 基站控制器根据用户的资源分配信息确定用户的天 线接收模式, 并按照该天线接收模式对应的 CE消耗准则对用户进行准入处 理; 本实施例由于以用户为粒度来配置同一基站或小区内不同用户的天线接 收模式, 因此可以分别满足各用户的上行接收性能, 同时, 由于本实施例以 用户的具体资源分配信息为依据进行配置, 不会造成盲目配置所带来的不必 要的资源浪费, 节省了运营商的硬件及基带处理资源的投资。
图 3为本发明天线接收模式的配置处理方法实施例三的流程图, 如图 3 所示, 本实施例提供了一种天线接收模式的配置处理方法, 具体为动态配置 方式, 可以具体包括如下步骤:
步骤 301 , 在用户申请建立或增加无线链路时, 基站将所述用户的天线 接收模式配置为第一天线接收模式。
在用户在基站下的某小区准备建立或增加无线链路时, 用户向基站发出 相应的无线链路申请,基站控制器可以在通过基站获取到该无线链路申请后, 统一按照第一天线接收模式对应的 CE消耗准则进行用户准入处理,本实施例 中的第一天线接收模式可以具体为 4天线接收模式, 后续的第二天线接收模 式可以具体为 2天线接收模式, 当然第一天线接收模式也可以具体为 2天线 接收模式, 第二天线接收模式也可以具体为 4天线接收模式, 此处仅是为了 后续描述方便而举例, 但优选地先将其配置为 4天线接收模式。 在用户准入 成功后, 基站先将用户的天线接收模式配置为第一天线接收模式, 基站为该 用户分配 4天线接收模式对应的天线基带处理资源。
步骤 302 ,基站实时监控当前剩余可用基带处理资源和 l i cens e CE数目。 基站在对新接入的用户的天线接收模式进行初始配置后, 对各已接入的 用户进行实时监控, 以在后续步骤中根据具体的监控结果来动态调整各已接 入的用户的天线接收模式。 在步骤中, 基站具体对网络中的当前剩余可用基 带处理资源和 l i cens e CE数目进行实时监控。
步骤 303 , 基站根据监控结果动态调整各已接入的用户的天线接收模式。 基站通过对当前剩余可用基带处理资源和 l i cense CE 数目进行实时监 控, 根据监控结果来对各接入的用户的天线接收模式进行动态调整; 若当前 剩余可用基带处理资源和 l i cense CE数目较少, 为满足后续新接入用户或切 换用户的资源需求, 可以将部分已接入的用户的天线接收模式进行调整, 如 下调其天线接收模式;进一步地,若当前剩余可用基带处理资源和 l i cense CE 数目充足时, 可以根据实际情况将之前被下调的用户的天线接收模式进行恢 复, 以尽可能为用户提供更好的接收质量。 其中, 本实施例中的对已接入的 用户的天线接收模式的调整包括维持天线接收模式不变的情况, 例如, 当当 前的天线接收模式为 4天线接收模式时, 通过监控当前剩余可用基带处理资 源和 l i cense CE数目, 如果当前剩余可用基带处理资源和 l i cense CE数目 充足时, 可以维持当前的 4天线接收模式不变。
具体地, 上述步骤 303可以具体为: 若监控结果为当前剩余可用基带处 理资源小于预设的资源门限值, 或许可 CE数目小于预设的数目门限值时, 基 站从已接入的用户中选择符合预设的选择策略的用户, 将选择的用户的天线 接收模式切换为第二天线接收模式。 即若监控到当前剩余可用基带处理资源 或许可 CE数据中的任意一项小于预设的门限值时,基站便从已接入的用户中 挑选部分符合预设的选择策略的用户, 将挑选的用户的天线接收模式从 4天 线接收模式下调为 1天线接收模式。 具体地, 本实施例中的符合预设的选择 策略的用户可以具体包括业务类型为数据用户、 且信号干扰比 (Si gna l Interference Ra te; 以下简称: SIR ) 大于预设的 SIR 目标值的用户, 以及 用户速率满足保证比特速率 (Guarantee Bi t Ra te; 以下简称: GBR )要求、 且优先级小于预设的优先级门限值的用户。 即若基站监控到当前剩余可用基 带处理资源小于预设的资源门限值, 或许可 CE 数目小于预设的数目门限值 时, 从已接入的用户中挑选业务类型为数据用户、 且 SIR大于预设的 SIR 目 标值的用户, 将其 4天线接收模式下调为 2天线接收模式, 或者从已接入的 用户中挑选已经保证了 GBR以及基本业务需求、 且优先级较低的用户, 将其 4天线接收模式下调为 2天线接收模式。
或者, 上述步骤 303还可以具体为: 若监控结果为当前剩余可用基带处 理资源大于或等于预设的资源门限值,且许可 CE数目大于或等于预设的数目 门限值时, 基站将已接入的用户中配置为第二天线接收模式的用户的天线接 收模式恢复为第一天线接收模式。 即若基站监控到当前剩余可用基带处理资 源和许可 CE数目均超过相应的门限值时,基站开始恢复已接入的用户中 2天 线接收模式的用户的天线接收模式, 将其上调为 4天线接收模式。
本实施例提供了一种天线接收模式的配置处理方法, 通过在用户申请建 立或增加无线链路时, 将用户的初始的天线接收模式均配置为第一天线接收 模式, 后续对当前剩余可用基带处理资源和许可 CE数目进行实时监控, 并根 据监控结果对各已接入的用户的天线接入模式进行调整; 本实施例由于以用 户为粒度来配置同一基站或小区内不同用户的天线接收模式, 因此可以分别 满足各用户的上行接收性能, 同时, 由于本实施例根据实时监控结果为依据 对各用户的天线接收模式进行调整, 不会造成盲目配置所带来的不必要的资 源浪费, 节省了运营商的硬件及基带处理资源的投资。
图 4为本发明天线接收模式的配置处理方法实施例四的流程图, 如图 4 所示, 本实施例提供了一种天线接收模式的配置处理方法, 具体为动态配置 方式, 可以具体包括如下步骤: 步骤 401 , 在用户申请建立或增加无线链路时, 基站将用户的天线接收 模式配置为 4天线接收模式, 本步骤可以与上述步骤 301类似, 此处不再赘 述。
步骤 402 , 基站判断用户的业务类型是否为语音用户, 如果是, 则执行 步骤 408 , 否则执行步骤 403。
基站在对一个用户的天线接收模式进行初始配置后, 可以对用户的业务 类型进行实时监控, 基站判断用户的业务类型是否为语音用户。 如果该用户 为语音用户, 由于语音用户所消耗的 CE数目较少, 且移动性较大, 对业务质 量要求也较高, 则执行后续步骤 408 , 基站可以维持该用户的 4天线接收模 式。 如果该用户为数据业务, 则可以再综合考虑该用户的信道质量、 用户速 率等信息来确定是否调整该用户的天线接收模式, 继续执行后续步骤 403。
步骤 403 , 基站判断用户的 SIR是否低于预设的 S IR 目标值, 如果是, 则执行步骤 408 , 否则执行步骤 404。
当基站获知该用户为数据用户时, 继续判断该用户的 SIR是否小于预设 的 SIR 目标值。 基站可以根据用户的上行 SIR测量结果以及外环功控的 S IR 目标值, 如果该用户的 SIR—直低于 SIR 目标值或者收敛较为困难, 说明该 用户已经处于小区边缘, 其发射功率受限, 则执行步骤 408 , 基站可以继续 维持该用户的 4天线接收模式。 如果该用户的 SIR—直高于 SIR目标值, 说 明该用户距离天线较近, 则可以考虑将其天线接收模式直接下调为 2天线接 收模式。
步骤 404 , 基站判断当前剩余可用基带处理资源是否小于预设的资源门 限值, 如果是, 则执行步骤 407 , 否则执行步骤 405。
基站对网络中的当前剩余可用基带处理资源进行监控, 判断当前余可用 基带处理资源是否小于预设的资源门限值, 如果是, 则执行后续步骤 407 , 否则执行步骤 405 , 继续监控网络中的许可 CE数目。
步骤 405 , 基站判断许可 CE数目是否小于预设的数目门限值, 如果是, 则执行步骤 407 , 否则执行步骤 406。
若当前剩余可用基带处理资源大于或等于预设的资源门限值, 但许可 CE 数目小于预设的数目门限值时, 基站也执行步骤 407。 若当前剩余可用基带 处理资源大于或等于预设的资源门限值,且许可 CE数目也大于或等于预设的 数目门限值时, 基站才执行步骤 406。
步骤 406 , 基站将已接入的用户中配置为 2 天线接收模式的用户的天线 接收模式恢复为 4天线接收模式, 并结束本流程。
若基站监控到当前剩余可用基带处理资源和许可 CE 数目均超过相应的 门限值时, 基站开始恢复已接入的用户中 2天线接收模式的用户的天线接收 模式, 将其上调为 4天线接收模式。
步骤 407 , 基站从已接入的用户中选择符合预设的选择策略的用户, 将 选择的所述用户的天线接收模式切换为 2天线接收模式, 并结束本流程。
若监控到当前剩余可用基带处理资源或许可 CE 数据中的任意一项小于 预设的门限值时, 基站便从已接入的用户中挑选部分符合预设的选择策略的 用户, 将挑选的用户的天线接收模式从 4天线接收模式下调为 2天线接收模 式。 具体地, 若基站监控到当前剩余可用基带处理资源小于预设的资源门限 值, 或许可 CE数目小于预设的数目门限值时, 从已接入的用户中挑选业务类 型为数据用户、 且 S IR大于预设的 S IR 目标值的用户, 将其 4天线接收模式 下调为 2天线接收模式, 或者从已接入的用户中挑选已经保证了 GBR以及基 本业务需求、 且优先级较低的用户, 将其 4天线接收模式下调为 2天线接收 模式。
步骤 408 , 基站维持用户的天线接收模式为 4天线接收模式。
进一步地, 在本实施例中, 基站还对天线接收模式的使用情况进行统计, 若发现当前剩余可用基带处理资源或者 license CE数目小于预设的数目门限 值, 且后续又挑选不到符合预设的选择策略的用户时, 说明当前的资源已经 受限, 基站对此进行打点, 作为扩容的依据之一。 本实施例提供了一种天线接收模式的配置处理方法, 通过在用户申请建 立或增加无线链路时, 将用户的初始的天线接收模式均配置为 4天线接收模 式, 后续对当前剩余可用基带处理资源和许可 CE数目进行实时监控, 并根据 监控结果对各已接入的用户的天线接入模式进行调整; 本实施例由于以用户 为粒度来配置同一基站或小区内不同用户的天线接收模式, 因此可以分别满 足各用户的上行接收性能, 同时, 由于本实施例根据实时监控结果为依据对 各用户的天线接收模式进行调整, 不会造成盲目配置所带来的不必要的资源 浪费, 节省了运营商的硬件及基带处理资源的投资。
图 5 为本发明天线接收模式的配置处理方法实施例五的流程图, 如图 5 所示, 本实施例提供了一种天线接收模式的配置处理方法, 具体为动态配置 方式, 且为上述实施例四的一个简化, 即只进行 4天线接收模式向 2天线接 收模式的单向调整, 本实施例可以具体包括如下步骤:
步骤 501 , 在用户申请建立或增加无线链路时, 基站将用户的天线接收模 式配置为 4天线接收模式, 本步骤可以与上述步骤 301类似, 此处不再赘述。
步骤 502 , 基站判断用户的业务类型是否为语音用户, 如果是, 则执行步 骤 507 , 否则执行步骤 503 , 本步骤可以与上述步骤 402类似, 此处不再赞述。
步骤 503 , 基站判断用户的 S IR是否低于预设的 S IR目标值, 如果是, 则 执行步骤 504 , 否则执行步骤 508。
当经过上述判断获知用户为数据业务时, 基站监控到用户的 S IR—直低 于 S IR 目标值或者收敛较为困难, 说明该用户已经处于小区边缘, 发射功率 受限, 则如果该用户当前为 2天线接收模式, 则不考虑将该用户从 2天线接 收模式切换到 4天线接收模式, 如果该用户当前为 4天线接收模式, 则维持 其天线接收模式。 在本实施例中, 若基站判断用户的 S IR低于预设的 S IR 目 标值时, 继续执行后续步骤 504 , 否则执行步骤 508 , 将配置为 4天线接收模 式的用户的天线接收模式下调为 1天线接收模式。
步骤 504 , 基站判断当前剩余可用基带处理资源是否小于预设的资源门 限值, 如果是, 则执行步骤 506 , 否则执行步骤 505 , 本步骤可以与上述步骤 404类似, 此处不再赘述。
步骤 505 , 基站判断许可 CE数目是否小于预设的数目门限值, 如果是, 则执行步骤 506 , 否则维持不变, 结束本流程。
若当前剩余可用基带处理资源大于或等于预设的资源门限值, 但许可 CE 数目小于预设的数目门限值时, 基站也执行步骤 506。 若当前剩余可用基带 处理资源大于或等于预设的资源门限值,且许可 CE数目也大于或等于预设的 数目门限值时, 基站不考虑上调用户的天线接收模式, 本流程结束。
步骤 506 , 基站从已接入的用户中选择符合预设的选择策略的用户, 将 选择的所述用户的天线接收模式切换为 2天线接收模式, 并结束本流程, 本 步骤可以与上述步骤 407类似, 此处不再赘述。
步骤 507 , 基站维持用户的天线接收模式为 4天线接收模式, 并结束本 流程。
步骤 508 , 基站将用户的天线接收模式下调为 2天线接收模式。
