本发明的基本思想是: 配置 PCU资源, 建立 PCU资源池; 根据 PS小 区实际的配置情况,将每个 PCU资源池中的 PCU资源分为空闲队列、拥塞 队列和闭塞队列; 从空闲队列中查找可用的 PCU资源分配给 PS小区, 并 根据分配的 PCU资源进行 PS小区与 PCU资源的动态绑定。
下面参照附图结合实施例对本发明做进一步的描述。
本发明的方案主要是根据 PS小区实际的配置情况, 将 PS小区与 PCU 资源动态绑定。 比如, 上电过程中根据 PS小区的实际配置载频进行动态绑 定, 并在无线操作维护中心 (OMCR )删除 PCU资源、 新增 PS小区等情 况下进行 PS小区与 PCU资源动态绑定的调整, 使 PCU资源的使用更加均 衡, 同时在 PCU资源故障时能够自动调整。
其次, 考虑到目前通信运营商的合作建网已经成为一种普遍的模式, 这种模式的优越性是实现了资源的共享, 节约了运营成本, 同时所带来的 缺点是: 这种模式也使得运营商失去了纯粹的独立性。 为了规避这个缺点, 本发明为各个运营商分别建立运营商专属的专用资源池(只有所属的运营 商可以使用, 其他运营商无权使用) 以保护运营商的独立性, 以及为所有 运营商共同建立共享资源池(所有运营商都可以使用的资源池) 以保证运 营商间的资源共享, 从而达到的效果是: 既能通过运营商间的资源共享满 足运营商的运营成本需求, 又能满足运营商的独立性需求。 以下具体阐述。
一种动态分配 PCU资源的方法, 主要包括以下内容:
步驟一、 OMCR根据运营商配置情况配置 PCU资源, 并将 PCU资源 分为专有资源和共享资源, 专有资源是指只能被某个运营商使用的 PCU资 源, 共享资源是指所有的运营商均可使用的 PCU资源。 专有资源位于专有 资源池, 共享资源位于共享资源池。
步驟二、基站控制器( BSC )收到配置的 PCU资源后,根据配置的 PCU 资源, 建立 PCU资源池, 即为各个运营商建立专有资源池和所有运营商均 可使用的共享资源池。 每个资源池(包括专有资源池和共享资源池)都分 为空闲、 闭塞、 拥塞 3个队列, 针对空闲队列而言, 空闲队列中的 PCU资 源还可以绑定 PS小区; 针对闭塞队列而言, 闭塞队列中的 PCU资源是指 出现故障的 PCU资源, 闭塞队列中的 PCU资源不可以用于绑定 PS小区; 针对拥塞队列而言, 拥塞队列中的 PCU资源绑定了最大额度的 PS小区或 者载频, 拥塞队列中的 PCU资源不可以用于绑定 PS小区。 为了实现 PCU资源的均衡实用, 为队列中的 PCU资源建立一个 KEY 值, 队列根据 KEY值进行排序, KEY值为一个 DWORD类型, DWORD 指 32个 Bit位, KEY值构成为: Bit30 Bit31位表示 PCU资源的实时负 荷等级, 分别为 0 1 2, 其中, 0代表负荷最低, 2表示负荷较高; Bit24-29 位为预留位, 直接为 0; BitO-23位表示根据 OMCR配置得到的 PCU资源 的繁忙度, 根据绑定的小区的配置计算得出, 计算公式如下所示:
KEY= ^可用 TRX个数 X小区繁忙度权值 公式 1
Cdl=l 可用 TRX个数 = GPRsTnt xRg + NumEDGETnt x Re 公式 2 其中, Num。PRSTlx和 NumED ETrX分别代表小区下配置的 GPRS载频和 EDGE 载频; Rg和 R6分别代表 GPRS载频和 EDGE载频对应的权重 , 在 OMCR 进行配置; 小区繁忙度是指 PS小区业务的繁忙度等级, 分为 5个等级, 由 OMCR进行配置。 KEY值的详细说明如以下表 1所示:
Figure imgf000009_0001
表 1
步驟三、 BSC根据配置的 PCU资源和 PS小区, 完成 PS小区与 PCU 资源的动态绑定与调整。
进一步, 需要触发 PS小区与 PCU资源进行动态绑定的情况包括但不 限于:
(一)、 PS小区未绑定 PCU资源。 具体的, 各单板初始上电完成, 正 常运行之后触发, 此时 PS小区未绑定 PCU资源, 所以要进行 PS小区与 PCU资源的动态绑定。
(二)、 OMCR删除 PS小区原有的 PCU资源, 需要重新绑定到其它的 PCU资源上。 具体的, 通过 OMCR更改 PCU资源配置时, 如果操作删除 PCU 资源, 并且该 PCU 资源在删除前有 PS 小区绑定在上面, 此时由于 OMCR删除了相应的 PCU资源,那么绑定在此 PCU资源的 PS小区无法进 行正常的业务, 所以要 4巴 PS小区从此 PCU资源上删除, 重新绑定到其它 的 PCU资源上。
(三;)、 OMCR配置新增 PS小区,新增 PS小区后, PS小区未绑定 PCU 资源。 具体的, OMCR新增配置 PS小区, 新增 PS小区后, PS小区未绑定 PCU资源时触发, 所以要触发 PS小区与 PCU资源的动态绑定。
(四)、 PCU资源业务量超过门限, 调整出去的 PS小区需要绑定到其 它空闲的 PCU资源。 具体的, 某 PCU资源业务量超过门限, 调整出去的 PS小区需要绑定到其它相对空闲的 PCU资源上:某 PCU资源业务量过大, 需要调整出去一些 PS小区, 解除 PS小区与此 PCU资源的绑定关系, 然后 把 PS小区绑定到业务量相对空闲的 PCU资源上。
一种动态分配 PCU资源的系统, 主要包括以下内容:
系统中的资源配置单元用于配置 PCU资源, 建立 PCU资源池; 根据 PS小区实际的配置情况,将每个 PCU资源池中的 PCU资源分为空闲队列、 拥塞队列和闭塞队列; 系统中的资源分配及绑定单元用于从空闲队列中查 找可用的 PCU资源分配给 PS小区, 并根据分配的 PCU资源进行 PS小区 与 PCU资源的动态绑定。
这里, 资源配置单元进一步用于根据 KEY值对 PCU资源排序后, 将 每个 PCU资源池中的 PCU资源分为空闲队列、 拥塞队列和闭塞队列。
其中, 所述 KEY值为表征 PCU上的载频个数、 PS小区业务繁忙度以 及 PCU资源实时负荷的值, 计算所述 KEY值采用的公式为: KEY= 可用 TRX个数 x小区繁忙度权值;
Cell=l
NumGPRSTrx xR„ + NumFnGFTrx xRp
所述可用 TRX个数 = ~~ s- ^2 Ξ 1 .
Rg + R e 其中, NumCPRSTra表示 PS小区下配置的 GPRS载频; NumEDETra表示
PS 小区下配置的 EDGE 载频; Rg表示 GPRS 载频对应的权重; Re表示
EDGE载频对应的权重; 小区繁忙度权值为 PS小区的业务的繁忙度等级。
这里, 资源分配及绑定单元进一步用于当 PS小区为具有专有 PCU资 源的运营商小区时, 先从其专属使用的专有资源池的空闲队列中查找可用 的 PCU资源,并分配给 PS小区进行绑定,如果未查找到可用的 PCU资源, 则再从共享资源池的空闲队列中查找可用的 PCU资源, 并分配给 PS小区 进行绑定; 当 PS小区为不具有专有 PCU资源的运营商小区时, 直接从共 享资源池的空闲队列中查找可用的 PCU资源, 并分配给 PS小区进行绑定。
以下对本发明进行举例阐述。
实例一:
如图 1所示为本发明的 PCU资源绑定一实例的示意图, 4巴 PCU资源划 分为专有 PCU资源和共享 PCU资源, 拥有专有 PCU资源的运营商小区优 先选择其所专属的、 用于存放专有 PCU资源的专有资源池, 以绑定到专有 PCU资源, 如果专有 PCU资源已满或者故障, 则该运营商小区还可以选择 所有运营商共享的、 用于存放共享 PCU资源的共享资源池, 以绑定到共享 PCU资源; 而没有专有 PCU资源的运营商小区则仅能直接到所有运营商共 享的、 用于存放共享 PCU资源的共享资源池, 以绑定到共享 PCU资源。
实例二:
如图 2所示为本发明装置中模块一实例的组成示意图, 包括资源配置 单元、 资源分配及绑定单元、 资源池。
其中, 资源配置单元用于配置 PCU资源,建立 PCU资源池, 维护 PCU 资源池中队列的更新。正常状态的 PCU资源进入空闲队列,故障状态的 PCU 资源进入闭塞队列; 绑定了最大额度的 PS小区或者载频的 PCU资源进入 拥塞队列。 故障的 PCU资源不能在绑定过程中使用。
其中, 资源分配及绑定单元在动态绑定被触发时查询资源池的空闲
PCU资源, 分配 PS小区需要的 PCU资源, 没有达到拥塞门限的 PCU资源 进入空闲队列, 拥塞的 PCU资源进入拥塞队列。
其中, 资源池(PCU Pool ) 由专有资源池和共享资源池组成。 通常情 况下有一个共享资源池和多个专有资源池, 比如配置 N个专有资源池, 图 2中的专有资源池可以为公众陆地移动通信网( PLMN ) 1~ PLMN N的专有 资源池, 也可以为同时容纳的多个不同的运营商配置专有资源池。 每个共 享资源池和专有资源池都分为空闲 (Idle )、 闭塞( Block )、 拥塞(Busy ) 三种队列。
实例三: 根据 PS小区实际的配置情况, 将 PS小区与 PCU资源动态绑 定时, 具体通过 KEY值划分空闲、 闭塞、 拥塞三种队列, 以便从空闲队列 中选取出空闲的 PCU资源进行动态绑定。
为实现各个 PCU资源上业务的相对均衡, PCU上的载频个数、 PS业 务繁忙度以及 PCU资源实时负荷用 KEY值(长度为一个 DWORD )表示。 需利用 KEY值划分空闲、 闭塞、 拥塞三种队列。
KEY值的 Bit31、 Bit30表示的是 PCU资源的实时负荷等级(0、 1、 2 ), 由 PCU资源单板进行实时上报; KEY值的 Bit24-29位置为预留位, 置 0; KEY值的 BitO-23位指的是根据 OMCR的配置参数计算的 PCU资源的繁忙 度, 主要包括: PS 小区的 GPRS载频和 EDGE载频及其对应的权重参数 Rg和 Re, PS小区业务的繁忙度, PS小区业务繁忙度和权值对应关系的对 照表如以下表 2所示。
Figure imgf000012_0001
繁忙度等级 (很少) (较少) (中等) (较繁忙) (很繁忙) 权值 0.1 0.6 1 1.5 2
表 2
KEY值的具体计算公式如上述公式 1和公式 2所示,此处对 KEY值的 具体计算方式进行说明为: PCU资源上配置的可用载频个数, 对 GPRS和 EDGE载频分别考虑, 利用已有的权重参数 Rg、 Re ( OMCR进行配置)进 行加权平均得到载频的加权个数。将载频的加权个数和 PS小区配置的业务 繁忙度参数相乘后每个 PS小区得到一个对应的值, 把 PCU资源上所有 PS 小区所得的值相加, 得到根据后台配置计算的 PCU资源的繁忙度, 结果放 在 KEY值的 BitO-23位。 根据 PCU资源上报的负荷等级, 放在 KEY值的 Bit30-31位, 组成完整的 KEY值。
每次进行动态的调整过程, 都需要调整 PCU资源的 KEY值, 重新对 PCU资源进行排序。 排序按照从小到大的顺序, 每次小区优先选择权值最 小的 PCU资源作为绑定的目标。对于配置了运营商标识的 PCU资源,仍然 按照上述计算方式计算 KEY值, 但是需要将配置给同一个运营商的多个 PCU资源单独进行排序, 不和共享的 PCU资源在一起排序。
初始上电时各队列中的 PCU资源按接入顺序排列, 为 PS小区动态分 配 PCU资源后或者 PCU上报负荷后调整各个涉及到的资源池中的 PCU资 源的 KEY值, 重新对 PCU资源进行排序。 排序按照从小到大的顺序, 每 次 PS小区优先选择权值最小的 PCU资源作为绑定的目标。
实例四:
如图 3所示为本发明的动态绑定 PS小区与 PCU资源的流程图, 动态 绑定流程是本发明的一个关键所在, 根据已有的 PCU资源, 对未进行绑定 的 PS小区绑定 PCU资源, 主要包括以下步驟:
步驟 410、 遍历所有小区, 查找未进行 PCU资源绑定的 PS小区, 如果 没有查找到未进行绑定的 PS小区, 则直接进入步驟 470; 如果查找到未进 行绑定的 PS小区, 则进入步驟 420。
步驟 420、 查找并判定判断未进行绑定的 PS小区的所属运营商是否有 专有的 PCU资源, 如果有, 则进入步驟 430; 如果没有, 则进入步驟 440。
步驟 430、在 PS小区所属的专有资源池中查找可用的 PCU资源, 以分 配 PS小区需要的 PCU资源, 并根据分配的 PCU资源进行 PS小区与 PCU 资源的动态绑定。 如果分配成功, 则进入步驟 450; 如果分配不成功, 则进 入步驟 440。
步驟 440、在共享资源池中进行 PS小区与 PCU资源的动态绑定, 查找 可用的 PCU资源, 以分配 PS小区需要的 PCU资源, 并根据分配的 PCU 资源进行 PS小区与 PCU资源的动态绑定。如果分配成功,则进入步驟 450; 如果分配不成功, 则进入步驟 460。
步驟 450、 选定 PCU资源之后, 更新 PCU资源的 KEY值及 PCU资源 队列。
步驟 460、 本小区绑定流程结束, 进入下一个未绑定 PCU 资源的 PS 小区的绑定流程。
步驟 470、 所有 PS小区绑定完成后, 更新相关数据中的绑定关系。 步驟 480、 发起存盘, 发起数据同步。
这里,对比本发明与现有技术,现有技术中采用运营商 PS小区和 PCU 资源固定绑定的配置方式,由于只分配小区所绑定的 PCU资源,因此, PCU 资源发生故障时会导致小区无法进行 PS业务, 只能通过人工参与重新调整 PS小区和 PCU资源的绑定来解决, 人工干预效率低, 在 PCU资源发生故 障时不利于业务开展。 而本发明这种动态绑定不仅解决了 PCU资源分配不 均衡的问题,提高了 PCU资源的使用效率, 而且同时在 PCU资源故障时能 够自动调整利于业务开展。 以下以实例五和实例六对这种状态发送变化的 情况(包括正常状态到故障状态、 和故障状态到正常状态)进行阐述。 实例五:
如图 4所示, 当 PCU资源状态由正常到故障时,或者新增 PCU资源时 如果此 PCU资源上已经绑定了 PS小区, 则需要调整 PS小区, 使 PS小区 重新绑定到正常的 PCU资源。 主要包括以下步驟:
步驟 510、 PCU资源故障, 通知动态绑定进程, 并在 PCU资源故障消 息中包括故障 PCU资源的相关信息。
这里, 本文的动态绑定进程由资源分配及绑定单元控制, 以下不作赘 述。
步驟 520、 动态绑定进程收到 PCU资源故障消息, 查找 PCU资源相关 信息, 判断当前是否已经存在该 PCU资源实例, 若存在, 则结束当前流程; 若不存在, 设置实例定时器 Tl。
这里, PCU资源实例即一个 PCU资源,判断当前是否已经存在该 PCU 资源实例指: 该 PCU资源发生故障已经存在。
步驟 530、 定时器 T1超时, 检查当前 PCU资源是否仍然故障, 若故障 则将超时计数器加 1 , 重新设置定时器 Tl。 定时器 T1超时次数达到 Ν次, 若 PCU资源仍然故障, 进入步驟 540; 若在 Ν次内, PCU资源状态正常, 直接结束当前流程。
步驟 540、 更新 PCU资源队列, 故障的 PCU资源进入闭塞队列, 并将 该 PCU资源记录在需要调整的 PCU资源序列中。
步驟 550、 由于 PCU资源故障后, 需要将其绑定的 PS小区重新绑定到 其它的 PCU资源上, 因此, 进入 PS小区与 PCU资源的动态绑定流程。
这里, 本步驟实现的动态绑定流程与上述实例四一样。
实例六:
如图 5所示,当 PCU资源状态由故障到正常时,或者新增 PCU资源时, 发起调整流程, 使得 PS小区在各个 PCU资源上均衡。 调整机制是优先调 整故障 PCU资源上的 PS小区到正常 PCU资源上, 而正常的 PCU资源上 的 PS小区, 考虑 PCU资源的权值差与平均值的比例超过一定值, 可以考 虑调整部分出来。 原则是在小区均衡的基础上, 尽量减少调整 PS小区的个 数。 主要包括以下步驟:
步驟 610、 PCU资源正常, 通知动态绑定进程, 并告知故障 PCU资源 的相关信息。
步驟 620、 动态绑定进程收到 PCU资源故障消息, 查找 PCU资源相关 信息, 判断当前是否已经存在该 PCU资源实例, 若存在, 则结束当前流程; 若不存在, 则设置实例定时器 T2。
这里, PCU资源实例即一个 PCU资源,判断当前是否已经存在该 PCU 资源实例指: 该 PCU资源故障解除已经存在。
步驟 630、 定时器 Τ2超时, 检查当前 PCU资源是否仍然正常, 若正常 则将超时计数器加 1 , 重新设置定时器 Τ2。 定时器 Τ2超时次数达到 Ν次, 若 PCU资源仍然正常, 进入步驟 640; 若在 Ν次内, PCU资源状态故障, 直接结束当前流程。
步驟 640、更新 PCU资源队列,将该 PCU资源记录在需要调整的 PCU 资源序列中。
步驟 650、 进入 PS小区与 PCU资源的动态绑定流程。
这里, 本步驟实现的动态绑定流程与上述实例四一样。
以上所述, 仅为本发明的较佳实施例而已, 并非用于限定本发明的保 护范围。 工业实用性
