Description

一种多模共传输时传输资源的管理方法和装置 技术领域
本发明涉及通讯领域的多模共传输技术, 特别是一种多模共传输时传 输资源的管理方法和装置。 背景技术
目前越来越多的电信设备厂商推出 2G、 3G共模的多模控制器, 多模 控制器使得 2G、 3G 的资源得到整合。 只要釆用一套多模控制器, 便可以 既支持 2G业务又可以支持 3G业务; 还可以先作为 2G单模使用, 后期需 要提供 3G业务时, 再作为多模使用, 大大减少了运营商的设备成本, 因此 受到越来越多的关注。
多模控制器在同时支持 2G、 3G业务时, 以 IP数据包的形式在各种物 理承载上传送信令、 业务数据及相关维护数据等, 目前常见的传输方式是: 基于 IP承载在整条 E1/T1上( IP over El/Tl )、 IP承载在部分 El/Tl上( IP over Fractional El/Tl )、 IP承载在信道化 STM-1上( IP over CSTM-1 )和 IP 承载在快速以太网或千兆以太网上( IP over FE/GE )等传输方式。
多模下 2G、 3G业务使用同一物理承载时, 目前业界有 2G、 3G共物理 传输时, 釆用将 3G的部分传输带宽分给 2G的做法, 如图 1所示, 主要包 括:
2G的基站控制台 ( BSC, Base Station Controller )至 2G的基站收发台 ( BTS , Base Transceiver Station )方向:
1)BSC将需要发送的 2G业务发送给 3G的无线网络控制器( RNC, Radio Network Controller ), 由 RNC统一将 3G业务和 2G业务通过传输网络发送 给 3G的基站 ( NodeB ); 2)NodeB将其中的 2G业务通过时隙交叉功能发送至 BTS; BTS至 BSC方向:
1) BTS将需要发送的 2G业务发送给 NodeB;
2) NodeB将 2G业务和 3G业务通过传输网络发送至 RNC;
3) RNC通过时隙交叉功能将 2G业务发送至 BSC。
这种技术实际是单模上的一种实现, NodeB与 BTS之间、 以及 RNC 与 BSC之间都要有直接的 E1/T1物理连接线, 且需要配置时隙交叉功能。
该技术下 2G、 3G业务只是在 RNC或 NodeB侧才被独立分开,在 RNC 和 NodeB之间的这段传输网络上是完全共用的, 如果这段时间大量的 2G 业务接入, 导致 RNC和 NodeB之间这段传输网络上传输的全是 2G业务, 那么就会挤压 3G业务, 使 3G业务的用户通话质量、 下载速率受到很大的 影响。
因此, 现有的共传输技术仅能做到使 2G、 3G业务共同在同一物理传 输网络上传送, 但并不能保证不同制式的业务质量和带宽的合理使用。 发明内容
有鉴于此, 本发明的主要目的在于提供一种多模共传输时传输资源的 管理方法和装置, 在保证业务质量的同时合理利用传输资源。

本发明的基本思想是: 在共享的传输资源池中, 配置专用资源和公共 资源; 当业务接入时, 获取所述公共资源的使用情况、 以及当前业务可用 专用资源的使用情况; 根据预先设置的资源分配策略和当前业务的传输资 源需求, 为当前业务分配合理的传输资源; 当业务结束时, 根据预先设置 的资源释放策略释放所分配的传输资源。
本发明实施例中以 2G、 3G制式的业务作为对象进行描述, 其他制式 业务的传输资源分配情况可依此类推。
目前, 由于 IP组网方式广泛应用, 多个不同制式的网元通过路由器、 交换机等中间设备共享多模控制器与传输网络之间的物理通道进行传输的 情况越来越常见, 如图 2所示, 后续实施例将都基于这种组网方式为例进 行描述。 本图是最简单的一个组网示意图, 网元级联等更加复杂的组网方 式, 其资源分配方法皆可由本技术领域的技术人员直接推导出。
本发明提供的多模共传输时传输资源的管理方法, 如图 3 所示, 包括 以下步骤:
步骤 301 : 在共享的传输资源池中, 配置专用资源和公共资源; 本步骤中, 将共享的物理传输资源 (简称传输资源池)按制式配置专 用资源, 再将剩余部分配置为公共资源, 或者, 按业务类型配置专用资源, 再将剩余部分配置为公共资源; 所述专用资源是指专门供某种制式网元或 某种业务类型使用的传输资源; 公共资源是指在传输资源池中供所有制式 网元或所有业务类型使用的传输资源; 所述业务类型根据业务需求而定, 包括但不仅限于: R99 非实时业务、 高速下行分组接入 ( HSDPA )业务等 类型。 本发明专利主要针对按制式配置资源进行描述, 按业务类型进行配 置的方法可依此类推。
其中, 专用资源和公共资源满足如下条件, 如图 3所示:
2(ϊ专用资源 + 3G专用资源 传输资源池带宽
公用资源 +AG专用资源 专用资源 = 源池带宽
其中,
用资源是供 2G、 G业务共同使用的公用资源;
S2G专用麵是供 2G业务使用的专用资源;
S3G专用麵是供 G业务使用的专用资源。
步骤 302: 当业务接入时, 获取所述公共资源的使用情况、 以及当前业 务可用专用资源的使用情况;
本步骤中, 当业务接入时, 根据传输资源池的专用资源和公共资源的 配置和使用情况, 获取所述公共资源的使用情况、 以及当前业务可用专用 资源的使用情况。
步骤 303: 根据预先设置的资源分配策略和当前业务的传输资源需求, 为当前业务分配合理的传输资源;
本步骤中, 公用资源、 专用资源的资源分配策略包括:
方法一: 先分配专用资源, 当专用资源使用完毕后, 再分配公共资源; 方法二: 先分配公共资源, 当公共资源使用完毕后, 再分配专用资源; 方法三: 公共资源和专用资源按照一定的比例进行分配。 例如: 当分 配 20%的专用资源时, 再开始分配公共资源。
无论釆用上述哪种资源分配策略, 最终对每个制式的业务来说, 占用 的资源都将是以下情形之一:
1 )仅占用专用资源;
2 ) 占用专用资源和公共资源;
3 )仅占用公共资源。 在本发明实施例中, 可以釆用方法一所述的资源分配策略为当前业务 进行资源分配, 且先分配本制式专用资源, 再分配其他制式专用资源, 最 后分配公共资源。 其他方法可依此类推, 这里不再赘述。
在资源分配成功后, 记录所述公共资源和专用资源的使用情况。
步骤 304: 当前业务结束时,根据预先设置的资源释放策略释放所分配 的传输资源。
本步骤中, 当前业务结束时, 公用资源、 专用资源的资源释放策略包 括:
方法一: 将从专用资源分配的资源释放回专用资源, 从公共资源分配 的资源释放回公共资源, 即:
从 S2G专用资源申请的资源, 要释放回 2G专用资源;
从 专用麵申请的资源, 要释放回 3G专用资源 ;
从 公用资源申请的资源, 要释放回 用资源 。
方法二: 将业务所占用的专用资源和公共资源的总和优先释放回本制 式网元占用的公共资源, 当将本制式网元占用的公共资源归还完毕后, 再 将该业务所占用的剩余资源释放回专用资源。
在本发明实施例中, 可以釆用方法一所述的资源释放策略进行描述, 其他方法可依此类推, 在此不做赞述。
在资源释放成功后, 记录所述公共资源和专用资源的使用情况。
下面通过具体实施例对本发明所述的方案进行详细描述。 在以下具体 实施例一到具体实施例六中, 资源分配策略均以方法一所述先分配专用资 源, 当专用资源使用完毕后, 再分配公共资源为例进行说明。
具体实施例一: 多模控制器在传输资源池中给每个网元配置固定的专 用资源, 但相同制式网元间的专用资源不共享, 同一网元不同制式的专用 资源不可共享; 即: N/;(2G专用资源) 专用资源 = W;(3G专用资源)
Figure imgf000010_0001
其中, NI表示网元, NI— 2G表示在该传输资源池上拥有 2G专用资源 的网元总数, N/ _ 3G表示在该传输资源池上拥有 3G专用资源的网元的总 数。
在本实施例中多模共传输时传输资源的管理方法, 包括以下步骤: 步骤 A1 : 根据当前接入业务的制式及本业务所属网元, 获取该网元内 该业务对应制式的专用资源使用情况、 及传输资源池中公共资源使用情况; 步骤 A2: 判断本网元内该业务对应制式的专用资源可用部分与公共资 源可用部分之和能否满足该业务需求; 如果能满足该业务需求, 则执行步 骤 A3 , 否则, 拒绝该业务接入, 结束当前流程;
步骤 A3: 判断本网元内该业务对应制式的可用专用资源能否满足该业 务需求; 当所述专用资源能满足该业务需求时, 则在本制式的专用资源中 为该业务分配传输资源; 当所述专用资源只能部分满足该业务需求时, 则 将本制式的可用专用资源中全部分配给该业务外, 再在公共资源中分配所 需剩余传输资源; 当所述专用资源已经用完, 则在公共资源中为该业务分 配传输资源; 至此, 本业务传输资源申请成功;
步骤 A4: 该业务结束时, 请求释放所分配的传输资源;
步骤 A5: 根据该业务所占用的专用资源和公共资源情况, 先释放该业 务所占用的公共资源, 再释放该业务所占用的本网元对应制式的专用资源。
例如: 以多模控制器下的 3G业务为例, 收到该 3G业务的传输资源申 请请求后, 得知该 3G业务在网元 1接入, 多模控制器通过上述资源配置情 况及业务特点, 获取网元 1的 3G专用资源 N1(3G专用资源)的使用情况、 及 当前 的使用情况;如果以上两种资源的可用部分之和不能满足该业务 需求, 则拒绝该业务接入; 如果以上两种资源的可用部分之和能满足业务 需求, 则判断 N1(3G专用资源)中能否满足该业务需求, 如果能满足该业务需 求, 则在 N1(3G专用资源)中为该业务分配传输资源; 如果 N1(3G专用资源)有可 用资源,但是不足以满足该业务的全部需求,则在 M(3G专用资源)和 公用资源中 为业务分配传输资源, 即该业务同时占用公用、 专用资源; 如果 N1(3G专用资源)已无可用传输资源, 则在 中为该业务分配传输资源。
当收到该业务的传输资源释放请求, 判断是否占用了 或专用资 源, 如果占用了 则将该业务所占用的公共资源释放回 如果 占用了专用资源, 则将该业务所占用的专用资源释放回 N1(3G专用资源)。 在 资源释放时, 为使资源利用更充分, 对于同时占用公用资源和专用资源的 业务, 可以进一步优化释放策略, 优先释放公用资源, 再释放专用资源 N1(3G专用资源)。
这种资源管理的方法, 既保证了本网元内有满足本制式业务质量的资 源, 同时, 也能充分利用空闲的公用资源, 达到既能保证业务质量, 又能 让不同制式业务充分利用共享资源的目的。
具体实施例二: 多模控制器在传输资源池中给每个网元配置固定的专 用资源, 但相同制式网元间的专用资源不共享, 同一网元内某种制式的专 用资源可以被其他制式占用。
在本实施例中多模共传输时传输资源的管理方法, 包括以下步骤: 步骤 B1 : 根据当前接入业务的制式和本业务所属网元, 获取该网元内 所有制式的专用资源使用情况、 及传输资源池中公共资源使用情况;
步骤 B2: 判断本网元内所有制式的专用资源可用部分与公共资源可用 部分之和能否满足该业务需求; 如果能满足该业务需求, 则执行步骤 B3 , 否则, 拒绝该业务接入, 结束当前流程;
步骤 B3: 判断本网元内该业务对应制式的专用资源能否满足该业务需 求; 当所述专用资源能满足该业务需求时, 则在本制式的专用资源中为该 业务分配传输资源; 当所述专用资源只能部分满足该业务需求时, 如果本 网元内其他制式的专用资源能满足该业务剩余部分的需求, 则在本制式的 专用资源中为该业务分配部分传输资源后, 在本网元内其他制式的专用资 源中为该业务分配剩余部分传输资源, 如果本网元内其他制式的专用资源 不能满足该业务剩余部分的需求, 则在本网元内其他制式的专用资源中分 配部分传输资源后, 在公共资源中为该业务分配剩余部分传输资源; 当本 网元内本制式专用资源已经用完时, 如果本网元内其他制式的专用资源能 够满足该业务需求, 则在本网元其他制式的专用资源为该业务分配传输资 源, 如果本网元内其他制式的专用资源还有部分可用资源, 但不足以满足 该业务需求, 则在本网元内其他制式的专用资源中为该业务分配部分传输 资源后, 在公共资源中为该业务分配剩余传输资源; 如果本网元内本制式 专用资源和其他制式的专用资源都已用完, 则在公共资源中为该业务分配 传输资源; 至此, 该业务传输资源申请成功;
步骤 B4: 该业务结束时, 请求释放所分配的传输资源;
步骤 B5 : 根据该业务所占用的专用资源和公共资源情况, 先释放该业 务所占用的公共资源, 再释放该业务所占用的本网元的专用资源。
例如: 以多模控制器下的 2G业务为例, 收到该 2G业务的传输资源申 请请求, 该 2G业务是在网元 2接入, 多模控制器通过上述资源配置情况及 业务特点, 获取网元 2 的 2G 专用资源 N2(2G专用资源)的使用情况、 N2(3G专用资源)的使用情况、 及当前 的使用情况。 如果上述三种资源 的可用部分之和不能满足该业务需求, 则拒绝该业务接入; 如果能满足该 业务需求,则判断 N2(2G专用资源)中能否满足业务需求,如果 N2(2G专用资源) 能满足业务需求, 则在 N2(2G专用资源)中为该 2G业务分配传输资源;
如果 N2(2G专用资源)有可用传输资源, 但是不足以满足该业务全部需 求, 而 N2(3G专用资源)可以满足业务的剩余部分传输资源, 则在 N2(2G专用资源)和 N2(3G专用资源)中为业务分配传输资源, 即业务同时占用 2G专用、 3G专用资源; 如果 N2(2G专用资源)有可用传输资源, 但是不足以 满足业务的全部需求, 而 N2(3G专用资源)也不足以满足业务的剩余部分需 求,则在 N2(2G专用资源)、 N2(3G专用资源)、 中为该业务分配传输资源; 如果 N2(2G专用资源)无可用传输资源, 而 N2(3G专用资源)足以满足业务 的全部需求, 则在 N2(3G专用资源) 中为业务分配传输资源; 如果 N2(2G专用资源)无可用传输资源, N2(3G专用资源)不足以满足业务的全部需 求, 则在 N2(3G专用资源)和 公用麵中为该业务分配传输资源;
如果 N2(2G专用资源)、 N2(3G专用资源)都已无可用传输资源, 则在 中为该业务分配传输资源。
当收到该业务的传输资源释放请求, 判断是否占用了 或专用资 源, 如果占用了 则将该业务所占用的公共资源释放回 如果 占 用 了 N2(2G专用资源) 、 N2(3G专用资源) , 则将资源分别释放回 N2(2G专用资源)、 N2(3G专用资源)。 在资源释放时, 为使资源利用更充分, 对于同时占用公用资源和 N2(2G专用资源)、 N2(3G专用资源)的 2G业务, 可以 进一步优化释放策略, 优先释放公用资源, 再释放本网元其他制式 N2(3G专用资源), 最后释放本网元本制式 N2(2G专用资源)。
这种资源管理的方法, 保证了本网元内有满足本制式业务质量的资源, 而且不同制式业务可共用本网元内的专用资源, 充分利用了本网元内的专 用资源。 同时, 也能充分利用空闲的公用资源, 达到既能保证业务质量, 又能让不同制式业务充分利用共享资源的目的。
具体实施例三: 多模控制器不为每个网元配置固定的专用资源, 即每 个网元初始拥有的传输资源为 0; 网元间相同制式的专用资源可共享, 即: 所有 2G网元都可使用传输资源池中的 2G专用资源, 所有 3G网元都可以 使用传输资源池中的 3G专用资源。
与具体实施例一相比, 每个网元的 N/ G专用资源)、 N/ G专用资源)大 小并不是固定的, 所有相同制式的网元都可以占用本制式的专用资源, 当 专用资源还有剩余时, 业务量多的网元占用的专用资源相对较多。
由上可知, 在本实施例中, 每个网元的专用资源仅是记录本网元在专 用资源中的占用情况, 不再作为资源是否足够的判别对象。
在本实施例中多模共传输时传输资源的管理方法为:
步骤 C1 : 根据当前接入业务的制式, 获取本业务对应制式的专用资源 使用情况、 及传输资源池中公共资源使用情况;
步骤 C2: 判断传输资源池中对应制式的专用资源可用部分与公共资源 可用部分之和能否满足该业务需求; 如果无法满足该业务需求, 则拒绝该 业务接入, 结束当前流程; 否则, 执行步骤 C3;
步骤 C3: 当该业务对应制式的专用资源能满足该业务需求时, 则在本 制式的专用资源中为该业务分配传输资源; 当该业务对应制式的专用资源 只能部分满足该业务需求时, 则在本制式的专用资源中分配部分传输资源 后, 在公共资源中分配剩余部分传输资源; 当该业务对应制式的专用资源 已经用完, 则在公共资源中为该业务分配传输资源; 至此, 该业务传输资 源申请成功;
步骤 C4: 该业务结束时, 请求释放所分配的传输资源;
步骤 C5: 根据该业务所占用的专用资源和公共资源情况, 先释放该业 务所占用的公共资源, 再释放该业务所占用的对应制式的专用资源。
例如: 以多模控制器下的 2G业务为例, 收到该 2G业务的传输资源申 请请求, 获取传输资源池中 2G专用资源 、 公用资源的使用情况, 如果以上两种资 源的可用部分之和不能满足该业务需求, 则拒绝该业务接入; 如果能满足 该业务需求,则判断 2 可用资源中能否满足该业务需求,如果 2C^ffl 能满足该业务需求, 则在 2ffl 中为该业务分配传输资源; 如果 2ffl 有可用资源, 但是不足以满足该业务全部需求, 则在
S2G专用资源和 公用资源中为 2G业务分配传输资源, 即业务同时占用公用、 2G专 用资源;
如果 2G专用资源无可用资源, 则在 公用资源中为该 2G业务分配传输资源。 当收到该业务的传输资源释放请求, 判断是否占用了 或专用资 源, 如果占用了 则将该业务所占用的公共资源释放回 如果 占用了专用资源, 则将资源释放回^。 ffl 。 在资源释放时, 为使资源利用 更充分, 对于同时占用公用资源和专用资源的业务, 可以进一步优化释放 策略, 优先将公用资源释放回 公用资源 , 再将专用资源释放回 2G专用资源。
这种资源管理的方法, 不区分网元, 使整个系统中本制式业务都使用 同一制式专用资源, 保证本制式业务总体呼叫数目和业务质量, 专用资源 使用更充分, 同时, 也能充分利用空闲的公用资源, 达到既能保证业务质 量, 又能让不同制式的业务充分利用共享资源的目的。
具体实施例四: 不为每个网元配置固定的专用资源, 网元间相同制式 专用资源可共享, 某种制式的专用资源在某种情况下可被其他制式占用。
本实施例与具体实施例三的区别在于, 一种制式可以使用其他制式的 专用资源。
在本实施例中多模共传输时传输资源的管理方法为:
步骤 D1 : 根据当前接入业务的制式, 获取本业务所有制式的专用资源 使用情况、 及传输资源池中公共资源使用情况;
步骤 D2: 判断传输资源池所有制式的专用资源可用部分与公用资源可 用部分之和是否能满足该业务需求; 如果无法满足该业务需求, 则拒绝该 业务接入, 结束当前流程; 否则, 执行步骤 D3;
步骤 D3: 当该业务对应制式的专用资源能满足该业务需求时, 则在本 制式的专用资源中为该业务分配传输资源; 当该业务对应制式的专用资源 只能部分满足该业务需求时, 如果其他制式的专用资源能满足该业务的剩 余部分需求, 则在其他制式的专用资源中为该业务分配剩余传输资源; 如 果其他制式的专用资源也不能满足该业务的剩余部分需求, 则在其他制式 的专用资源中为该业务分配部分传输资源后, 在公用资源中再为业务分配 剩余传输资源; 当该业务对应制式的专用资源已经用完, 其他制式的专用 资源可以满足该业务需求, 则在其他制式的专用资源中为该业务分配传输 资源; 当该业务对应制式的专用资源已经用完, 而其他制式的专用资源还 有部分可用资源, 但不足以完全满足该业务需求, 则在其他制式的专用资 源中为该业务分配部分传输资源后, 在公用资源中为该业务分配剩余传输 资源; 当该业务对应制式的专用资源和其他制式的专用资源都已经用完, 则在公共资源中为该业务分配传输资源; 至此, 该业务传输资源申请成功; 步骤 D4: 该业务结束时, 请求释放所分配的传输资源;
步骤 D5: 根据该业务所占用的专用资源和公共资源情况, 先释放该业 务所占用的公共资源, 再释放该业务所占用的专用资源。
例如: 以多模控制器下的 3G业务为例, 收到该 3G业务的传输资源申 请请求后, 多模控制器通过上述资源配置和业务特点, 获取 3ffl 的使用 情况、 2。专用资源的使用情况、 及当前 S公用资源的使用情况。 当以上三种资源的 可用部分之和不能满足业务需求时, 则拒绝该业务接入; 当以上三种资源 的可用部分之和能满足业务需求时,
如果 3。专用资源能满足业务需求, 则在 3。专用资源中为该 3G业务分配传输资 源;
如果 3G专用麵有可用资源,但不足以满足该业务全部需求, 而 2G专用资源可 以满足业务的剩余需求,则在 S3G专用资源和 S2G专用资源中为业务分配传输资源, 即 业务同时占用 3G专用、 2G专用资源; 如果 ¾。 ffl 有可用资源,但是不足以满足业务的全部需求, 82。 也 不足以满足业务的剩余部分需求, 则在 3G专用资源 、 β2。专用资源 、 公用资源中为该业 务分配传输资源;
如果 3G专用麵无可用资源, 2G专用麵足以满足业务的全部需求, 则在
&_。专用资源中为业务分配传输资源;
如果 3G专用麵无可用资源, 2G专用麵不足以满足业务的全部需求, 则在
S2G专用资源和 公用资源中为该业务分配传输资源;
如果 。专用资源 、 专用资源都已无可用资源, 则在 公用资源中为该业务分配传 输资源。
当收到该业务的传输资源释放请求, 判断是否占用了 ^ 或专用资 源, 如果占用了 公用资源 , 则将资源释放回 公用资源 , 如果占用了 S3G专用资源 、 B2Gmm ^ 则将资源分别释放回 3G专用资源 、 B2QM 0 释放时, 为使资源利用 更充分, 对于同时占用公用资源和 3G专用资源 、 S2G专用资源的 3G业务, 可以进一 步优化释放策略, 优先将公用资源释放回 , 再将 2G专用资源释放回 2G专用资源 , 最后将 3G专用资源释放回 3G专用资源 。
这种资源管理的方法, 通过优先使用本制式专用资源, 再使用其他制 式专用资源的方式, 既保证了有满足本制式业务质量的资源, 同时, 也能 充分利用其他制式空闲的专用资源和空闲的公用资源, 达到既能保证业务 质量, 又使不同制式业务充分利用共享资源的目的。
具体实施例五: 多模控制器在传输资源池中按制式配置所有网元的公 用资源、 专用资源, 同时网元本身也配置了一定的专用资源和公用资源, 但是, 网元本身配置的公共资源和专用资源与传输资源池中配置的公共资 源和本制式专用资源没有——对应的关系。
本实施例中, 网元本身拥有的传输资源、 所有网元共享的传输资源池 中都同时按制式配置专用资源、 公用资源, 相同制式网元间可共享传输资 源池中的本制式专用资源。 但网元本身的资源配置与传输资源池中的资源 配置无——对应关系, 两者没有必然联系, 即:
B2e ffl¾ 不一定等于 M∑fN ;(2G专用资源);
B3e ffl¾ 不一定等于 N/;(3G专用资源);
Figure imgf000018_0001
NI{ (所有资源) = 专用资源) + N//3G专用资源) + ;(公用资源);
其中, 如果网元 N 是 2G网元, 则 N/ G专用资源)为 0,
如果网元 N/i是 3G网元, 则 N/ G专用资源)为 0 ,
如果网元 N/i是多模网元, 根据网元需求配置专用资源。
网元中虽然也配置了 N/i(2G专用资源)、 N/ G专用资源), 但是最终能否 成功占用传输资源池中专用资源, 还是由传输资源池中的资源情况决定, 并不受网元的资源配置限制。
本实施例中的资源管理步骤与具体实施例三、 具体实施例四相似, 但 不同的是, 业务申请传输资源时, 需要进行两步判断:
第一步, 本网元传输资源的公用、 专用资源使用情况的判别; 这时, 将具体实施例三或具体实施例四中的"传输资源池"替换为"本网元传输资 源"即可;
第二步, 传输资源池中公用、 专用资源使用情况的判别; 这时, 按照 具体实施例三或具体实施例四中描述即可。
只有当上述两个步骤都成功时, 业务才能成功申请所需传输资源。 传输资源释放过程同上描述, 在传输资源池占用的资源释放回传输资 源池中的公用资源、 专用资源, 在本网元传输资源占用的资源释放回本网 元传输资源中的公用资源、 专用资源。
这种资源管理的方法, 首先通过网元内公用资源和专用资源的分配, 保证本网元内的资源分配达到需求, 同时, 也能充分利用空闲的专用资源 和空闲的公用资源, 达到既能保证业务质量, 又使不同制式业务充分利用 共享资源的目的。
具体实施例六: 多模控制器在每一种制式的专用资源中配置本制式网 元间共享资源和本制式网元专用资源, 本制式所有网元都可使用网元间共 享资源, 但本制式网元专用资源不可共享。
本实施例是具体实施例一和具体实施例三的组合, 本实施例中, 存在 下述关系:
NI _2G
专用资源 = ^2(?网元间共享资源 + NIf2G^^ )
i=l
NI _ G
S3G专用资源 = S3G网元间共享资源 + Λ^(3(7专用资源)
i=l
网元的 N/i(2G专用资源)、 N/ G专用资源)是固定的, 相同制式网元间专 用资源不可共享。
在本实施例中所述资源管理的方法为:
对于 N/i(2G专用资源)、 N/ G专用资源)这部分资源的使用, 参见具体实 施例一中描述。
对于 2G网元间共享资源 、 3G网元间共享资源这部分资源的使用,参考具体实施例三中 描述, 将具体实施例三中 2G专用资源 、 3G专用资源换成 2G网元间共享资源 、 3G网元间共享资源描 述即可。
为实现上述方法, 本发明还提供了一种多模共传输时传输资源的分配 装置, 如图 4所示, 包括: 资源配置及获取模块、 资源分配模块; 其中, 资源配置及获取模块, 用于在共享的传输资源池中, 配置专用资源和 公共资源, 并当业务接入时, 获取所述公共资源的使用情况、 以及当前业 务可用专用资源的使用情况;
资源分配模块, 用于设置资源分配策略, 以及根据预先设置的资源分 配策略和当前业务的传输资源需求, 为当前业务分配合理的传输资源。 所述资源配置及获取模块, 还用于在资源分配成功或资源释放成功后, 记录所述公共资源和专用资源的使用情况。
所述资源配置及获取模块配置专用资源和公共资源, 为: 按业务制式 配置专用资源, 再将剩余部分配置为公共资源, 或者, 按业务类型配置专 用资源, 再将剩余部分配置为公共资源。
所述资源分配模块设置资源分配策略, 包括: 先分配专用资源, 当专 用资源使用完毕后, 再分配公共资源; 或者, 先分配公共资源, 当公共资 源使用完毕后, 在分配专用资源; 公共资源和专用资源按照一定的比例进 行分配。
所述资源分配模块为当前业务分配合理的传输资源, 为: 在当前业务 接入时, 当公共资源和当前业务可用专用资源之和不满足当前业务需求时, 则拒绝该业务接入; 否则, 根据所述资源分配策略为当前业务分配合理的 传输资源。
所述该装置还包括: 资源释放模块, 用于根据预先设置的资源释放策 略释放所分配的传输资源。
所述资源释放模块所设置的资源释放策略, 包括: 将从专用资源分配 的资源释放回专用资源, 从公共资源分配的资源释放回公共资源; 或者, 将所占用资源的总和优先释放回公共资源, 再将剩余资源释放回专用资源。
