Description

发送及接收负载信息的方法、 接入网控制节点及系统 本申请要求于 2011年 3月 22日提交中国专利局、 申请号为 201110069383.4、 发明名称为"发送及接收负载信息的方法、 接入网控制节点 及系统"的中国专利申请的优先权, 其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信领域, 特别涉及发送及接收负载信息的方法、 接入网控 制节点及系统。 背景技术
随着全球变暖现象的日益严重, 节能已经成为众多运营商的目标之一。 为了减少运营成本和保护环境, 许多节能措施应用在通信网络中。 例如, 在 目前阶段, 通信网给存在 GSM ( Global System for Mobile communications, 全球移动通信系统 )、 UTMS ( Universal Mobile Telecommunications System, 通用移动通信系统)、 LTE ( Long Term Evolution, 长期演进网络)共存的情 况, 为了使得网络资源得到最大的利用和节约资源, 通常会采取根据小区的 负载情况进行小区的关闭和切换的方式实现网络资源的合理分配和节约资 源。
为了实现小区的关闭和切换, 通常小区之间会传递小区的负载信息, 接 入网控制节点根据本小区和相邻小区的负载信息, 对小区进行关闭和切换的 操作。 但是, 在目前阶段, 相邻小区之间的接入网控制节点之间并不能进行 直接的负载信息交互, 需要通过 RIM ( RAN Information Management, 无线 接入网信息管理) 流程或在 CS ( Circuit Switched, 电路交换)切换流程相关 信息中进行交互。其中, RIM流程将本小区的负载信息使用 Gb接口经过 SGSN ( Serving GPRS Support Node,分组无线业务服务支持节点 )发送给相邻小区 的接入网控制节点, CS切换流程相关信息中将本小区的负载信息通过 A接口 经过 MSC ( Mobile Switching Center, 移动交换中心 )发送给相邻小区的接入 网控制节点。 并且, 小区之间在进行负载信息的交互时, 其负载信息只包括 物理信道资源的占用情况。 当某个小区的负载持续保持在一个较低门限值之 下时, 可以选择将其中一种或多种制式的小区关闭。 当负载过高时, 则将关 闭的小区打开分担负载。 因为在现有流程中交互的负载信息中只包括本小区网络资源中物理资源 的占用, 接入网控制节点不能根据所接收到的负载信息准确的判断关闭或切 换小区, 可能造成错误关闭小区或切换小区的情况, 使得网络资源不能得到 合理的应用。 发明内容

第一、 业务支持指示可以占用 1个比特, 用于指示当前开启的网络的网络 制式是否支持当前业务。
例如,可以用比特 0来指示当前开启的网络的网络制式支持当前业务以及 用比特 1来指示当前开启的网络的网络制式不支持当前业务。
第二、 业务支持指示可以占用多个比特, 用于指示哪些网络制式可以支 持当前业务。 例如, 可以用比特 00来指示所有网络制式都支持当前业务, 用 01来指示 只有 LTE网络支持当前业务, 用 10来指示只有 UMTS网络支持当前业务,用 11 来指示 UMTS网络和 LTE网络都支持当前业务。
相应地, 上述通过该业务支持指示获取当前业务的子业务类型, 具体的 包括:
根据该业务支持指示得到当前业务可以使用的网络制式类型, 根据上述 当前业务可以使用的网络制式类型为当前业务指派子业务类型。
例如,当业务支持指示中得到当前业务可以使用的网络制式类型为: GSM 支持当前业务, 而 LTE不支持当前业务, 并且由于步骤 201中的判断可知当 前业务为 CS业务, 则可将当前业务的子业务类型指派为普通通话类型。
第三、 业务支持指示可以占用多个比特, 用于指示当前业务的子业务类 型。
例如, 可以用比特 00来指示子业务类型为普通通话业务, 用 01来指示子 业务类型为数据 /传真等。
201-3、 接收移动终端发送的分组资源请求, 通过该分组资源请求获得当 前业务的子业务类型, 执行步骤 201-4;
其中, 上述分组资源请求中携带有用于指示当前业务的子业务类型的指 示。
201-4、 统计当前业务的信道占有率;
进一步地, 统计当前业务的信道占有率可以有多种表示方式, 在本实施 例中, 优选地采用话务量进行表示, 以 Erl (爱尔兰)为单位。
201-5、 根据子业务类型指示中的子业务类型分别统计本小区中各个子业 务类型的信道占有率, 分别得到本小区中各个子业务类型的负载数据, 并将 上述负载数据组成负载信息。
需要说明的是, 上述负载信息具体的包括小区标识、 业务类型、 不同的 业务类型的子业务类型的负载数据, 小区总的负载数据, 具体如表 2所示: 表 2
Cell ID Service Sub service type Load information type
(小区标
(子业务类型) (负载数据)
(业务类 型)
Cell A cs CS conversation (普通通话 ) • . .
Cell A cs Data/Fax (数据 /传真) • . .
Cell A PS Streaming (流 ) • . .
Cell A PS Interacting (交互类) • . .
Cell A Whole • . .
其中, 各个业务类型或子业务类型的负载数据可以有多种表示方式, 在 本实施例中, 优选地采用话务量进行表示, 以 Erl (爱尔兰)为单位。
步骤 202、 第一接入网控制节点接收第二接入网控制节点发送的负载信 息查询请求;
需要说明的是, 第二接入网控制节点具体包括 BSC、 RNC或 eNodeB , 但是小区 A和第二接入网控制节点不一定相同, 例如, 第一接入网控制节点 可以为 BSC , 第二接入网控制节点为 RNC , 这样的情况是同样可以进行负载 信息的交互的。
步骤 203、 小区 A向第二接入网控制节点发送上述负载信息;
进一步地, 步骤 202和 203还可以使用下面步骤进行替换: 小区 A向第 二接入网控制节点周期性的发送负载信息。
在本实施例中, 在第一接入网控制节点向第二接入网控制节点发送负载 信息时, 建立第一接入网控制节点与第二接入网控制节点之间的通信信道, 例如可以通过 Iur-g 或 X2接口向第二接入网控制节点发送负载信息, 其中 Iur-g接口可以在两个 RNC之间、 两个 BSC(Iu模式、 A/Gb模式)之间, 以及 RNC与 BSC(Iu模式、 A/Gb模式)之间, X2接口为在两个 eNodeB之间使用。
需要说明的是, 在现有技术中, 通信网络由终端、 接入网和核心网组成, 各个小区的接入网控制节点属于接入网,它们之间不能直接进行信息的交互, 在各个小区的接入网控制节点之间进行负载信息的交互时, 必须通过核心网 的转发。 例如, 在目前阶段各个小区的接入网控制节点直接进行负载信息交 互时, 使用 RIM流程或在 CS切换流程相关信息中进行交互。 其中, RIM流 程将负载信息通过 Gb接口经过 SGSN向相邻小区的接入网控制节点进行转 发,在 CS切换流程相关信息中将负载信息通过 A接口经过 MSC向相邻小区 的接入网控制节点进行转发, 皆需要通过转发的形式向相邻小区发送负载信 息, 占用了过多的网络资源, 采用本实施例所提供的负载信息发送方式可以 节省网络资源。
步骤 204、 第二接入网控制节点根据自身的负载信息和小区 A的负载信 息对业务进行控制。
需要说明的是, 在本实施例中, 步骤 204前还包括: 第二接入网控制节 点统计自身的负载信息。
其中, 小区 B统计自身的负载信息的方法与小区 A中统计负载信息的方 法相同, 这里不再赘述。
在本实施例中, 第二接入网控制节点对业务进行控制具体包括, 对本小 区进行关闭操作和对本小区中的 UE进行小区间切换的操作。
其中, 如图 4所示, 第二接入网控制节点根据自身的负载信息和小区 A 的负载信息对小区进行关闭操作, 具体包括:
204-1、第二接入网控制节点判断小区 A的整体负载是否低于预设的第一 门限, 如果是, 执行步骤 204-4, 如果不是, 执行步骤 204-2;
其中, 整体负载包括 CS业务和 PS业务的负载。
204-2、 第二接入网控制节点判断小区 B是否支持小区 A中高负载的业 务, 如果是, 执行步骤 204-3 , 如果不是, 执行步骤 204-4;
需要说明的是, 在本实施例中, 业务具体指 UE与当前网络进行的操作, 若干种业务可以划分到一个子业务类型中,若干个子业务类型又可归类到 CS 业务或 PS业务, 如上述表 2所示为所属分类划分的一种方式。
204-3、 保留在小区 B中的上述高负载的业务的信道;
需要说明的是, 本步骤还可以包括, 关闭其他业务的信道, 仅保留上述 高负载的业务的信道。
204-4、第二接入网控制节点判断小区 B的整体负载是否低于预设的第二 门限, 如果是, 执行步骤 204-5 , 如果不是, 则小区 B不能关闭;
204-5、 第二接入网控制节点判断小区 B是否存在小区 A不能承载的业 务, 如果是, 执行步骤 204-6, 如果不是, 执行步骤 204-7;
204-6、 保留小区 B中上述小区 A不能承载的业务所使用的信道;
204-7、 关闭整个小区。 进一步地, 在第二接入网控制节点接到第一接入网控制节点发送的负载 信息时, 本方法还包括:
判断小区 Α的整体负载是否低于预设的第一门限;
如果是, 则保持小区 B原小区开启状态不变;
如果不是, 则第二接入网控制节点判断小区 B是否支持小区 A中高负载 的业务;
如果支持,则打开小区 B中支持上述小区 A中高负载的业务的信道; 如果不支持, 则保持小区 B原小区开启状态不变。
如图 5所示, 第二接入网控制节点才艮据小区 B的负载信息和小区 A的负 载信息对 UE进行小区间切换的操作, 具体包括:
204- , 第二接入网控制节点判断小区 B的整体负载是否低于预设的第 二门限, 如果是, 终止 UE的小区间切换判断的流程, 如果不是, 执行步骤 204-2';
204-2'、 第二接入网控制节点启动基于负载的切换判断, 判断小区 A的 整体负载是否低于预设的第一门限, 如果是, 执行步骤 204-3' , 如果不是, 执行步骤 204-6';
204-3'、 判断小区 A是否支持小区 B中负载高的业务, 如果是, 执行步 骤 204-4' , 如果不是, 执行步骤 204-6' ;
204-4'、 判断小区 A中上述负载高的业务的负载是否低于预设的第三门 限, 如果是, 执行步骤 204-5' , 如果不是, 执行步骤 204-6、
204-5'、 选定小区 A, 执行小区间切换的操作;
在本步骤中, 执行小区间切换的操作, 具体的为, 将用户终端从小区 B 切换到小区 A进行业务, 使得用户在进行上述负载高的业务时, 由小区 A提 供 务, 以减少小区 B的负载。
需要说明的是, 执行对本小区中的 UE进行小区间切换时, 包括相同制 式的相邻小区之间的切换和不同制式的小区之间的切换。
204-6'、 选定下一个目标小区, 执行 UE的小区间切换的判断流程。 在本步骤中, 对下一个目标小区执行 UE的小区间切换的判断流程, 与 步骤 204-2' 到步骤 204-6' 中的方法相同。
需要说明的是, 在本实施例中, 第一接入网控制节点负责执行对小区 A 的管理, 第二接入网控制节点负责执行对小区 B的管理, 小区 A和小区 B互 为相邻小区, 第一接入网控制节点和第二接入网控制节点可以为两个节点, 也可以为同一个节点, 当第一接入网控制节点和第二接入网控制节点为同一 个节点时, 第一接入网控制节点向第二接入网控制节点发送负载信息为内部 负载信息的传递。 本发明实施例所提供的负载信息交互的方法, 通过将小区的负载信息基 于 CS业务和 PS业务的子业务类型进行统计, 使得负载信息更加准确, 并将 准确的负载信息在小区之间互相传递, 使得小区可以根据自身和其他相邻小 区的负载信息准确的进行本小区的关闭操作和 /或对 UE进行小区间切换的操 作, 使网络资源得到合理的利用。
而在现有技术中, 小区之间在进行负载信息的交互时, 只包括物理信道 资源的占用, 不能区分出具体的子业务类型。 例如, 在某小区中, CS业务负 载很高, PS业务负载很低, 例如语音业务负载很高, 因为 LTE小区不能负责 语音业务, 因此则可以根据本发明的方法, 对 LTE小区进行关闭; 而在现有 技术中, 不能区分具体的为哪种业务的负载很高, 不能判断 LTE小区是否支 持该业务, 则无法关闭 LTE小区以节省资源。
因此, 本发明提供的负载信息交互的方法, 可以使得小区之间的负载信 息更加准确,通过准确的负载信息进行本小区的关闭操作和对本小区中的 UE 进行小区间切换的操作, 可以将资源利用的更加充分且避免错误的切换和关 闭的情况的出现。 实施例 3
