3GPP ( the 3rd Generation Partnership Project )标准中定义的长期演进无 线( Long Term Evolution, 简称 LTE ) 网络架构分为 LTE网络的无线接入网 ( Evolved Universal Terrestrial Radio Access Network,简称 EUTRAN )和 LTE 网络的分组核心网 (Evolved Package Core, 简称 EPC )两部分: EUTRAN由 演进基站(evolved Node Base , 简称 eNB )组成, EPC由移动性管理实体 ( Mobility Management Entity, 简称 MME ) 、 月良务网关 ( Serving Gateway, 简称 S-GW )等组成。 EUTRAN与 EPC的互联接口 S1接口, 细分为 eNB与 MME之间的 Sl-MME信令面接口(SI for the control plane), eNB与 S-GW之 间的 S 1 -U用户面接口(S 1 for the user plane)。 由于 LTE网络架构的扁平化, 多个 eNB可以接入同一个核心网设备, 同一 eNB也可以接入不同的核心网 设备。 对于同一 eNB接入多个核心网设备场景, 通常这些多个核心网设备归 属同一运营商, 考虑部分区域频率资源或站点选址困难, 为了提高资源的利 用率, 这些多核心网也可能归属不同运营商。
对于 Sl-MME接口 , MME侧 Sl-MME接口的信令资源不足时, MME 会通过 Sl-MME接口的信令消息通知 eNB减少与 MME的信令的连接。然而, 在 eNB侧 Sl-MME接口的信令资源不足时, eNB侧没有过载处理机制。 eNB 侧 Sl-MME接口的信令资源不足时, 会降低 eNB侧接入用户的业务质量和 eNB侧的信令资源利用率。
对于 S1-U接口, eNB与 MME定义用户准入的最大带宽,只负责分配下 属 S-GW无线资源, 不关注 S-GW传输资源是否充裕, S1-U接口也没有过载 处理机制。 因此, S1-U接口的传输资源受限时,将会导致业务拥塞甚至丟包, 降低传输资源利用率。 发明内容

首先阐述本发明实施例提供的信令资源过载处理方法。
图 1为本发明提供的信令资源过载处理方法实施例流程图。 本实施例提 供了基站侧信令资源过载处理方法。 如图 1所示, 本实施例包括:
步骤 11 : 基站控制设备统计信令接口的信令资源利用率; 信令接口为基 站控制设备与信令面控制实体之间的接口。
本发明实施例提供的信令资源过载处理方法, 适应于基站控制设备接入 一个核心网设备的场景,也适应于基站控制设备接入多个核心网设备的场景。 适应的通信网络包括 2G网络、 3G网络和 4G网络以及更高级的网络制式的 网络中的信令接口,还可适用于全球微波互联接入( Worldwide Interoperability for Microwave Access, 简称 Wimax )扁平化网络。 其中, 2G网络可为全球 移动通讯系统( Global System for Mobile Communications, 简称 GSM )网络, 3G网络可为通用移动通讯系统( Universal Mobile Telecommunications System, 简称 UMTS ) 网络。 信令面控制实体在 LTE网络中可为 MME。 在 LTE网络 中, eNB的功能包括传统基站和传统基站控制器所具有的功能, 本发明实施 例中基站控制设备在 LTE网络中可对应于 eNB中与传统基站控制器的功能相 近的模块。 在 2G网络中分别为 MGW ( Media Gateway, 媒体网关)和 BSC, 在 3G网络中 MGW和 RNC。信令接口具体可为 eNB与 MME之间的 S1-MME 接口, 在 UMTS网络中为 RNC与 MGW之间的 luCS接口, 在 GSM网络中 为 BSC和 MGW之间的 A接口。
步骤 12: 在信令资源利用率大于等于第一门限值时, 基站控制设备向信 令面控制实体发送信令资源过载消息以通知信令面控制实体减少与基站控制 设备的信令连接。
当信令资源利用率大于等于第一门限值时, 基站控制设备通知 MME减 少与基站控制设备的信令连接。 进一步, 基站控制设备通知 MME减少与基 站控制设备的信令连接的同时, 基站控制设备还可阻塞用户接入。
进一步, 如果基站控制设备后续统计到的信令资源利用率小于等于第二 门限值时, 基站控制设备允许用户接入, 同时向信令面实体发送信令资源过 载解除消息, 以通知信令面实体增加与基站控制设备的信令连接。 其中, 第 二门限值小于第一门限值。
进一步, 不同运营商可在各自签订的 QoS策略中设置第一门限值和第二 门限值。 根据运营商的 QoS策略, 基站控制设备统计到信令资源利用率大于 等于第一门限值时, 向该运营商的信令面控制实体发送信令资源过载消息; 统计到信令资源利用率小于等于第二门限值时, 向该运营商的信令面实体发 送信令资源过载解除消息。
本发明实施例信令资源过载处理方法, 不同运营商的信令面控制实体与 基站控制设备建立信令连接后, 在基站控制设备资源受限的情况下, 基站控 制设备发送信令资源过载消息通知不同运营商信令面控制实体减少与基站控 制设备的信令连接, 从而降低对当前接入用户的业务质量的影响, 提高基站 控制设备的无线资源利用率。 通过本发明提供的方法基站控制设备可根据签 订的 QoS策略, 判断本端无线资源是否受限并向信令面控制实体发送信令资 源过载消息。
以下阐述本发明实施例提供的传输资源过载处理方法。 根据本发明实施 例提供的传输资源过载处理方法, 各网元对本端的资源负载进行统计, 各网 元向指定的中心节点上报本端的传输资源负载, 通过指定的中心节点进行负 载判决, 之后中心节点通知相应网元进行过载处理。 指向的中心节点也可根 据各网元上报的传输资源负责, 对各网元的流量进行监管并调整, 为网络扩 容升级提供必要支撑。 本发明实施例提供的传输资源过载处理方法, 适应于 基站控制设备接入一个核心网设备的场景, 也适应于基站控制设备接入多个 核心网设备的场景。 适应的通信网络包括 2G网络、 3G网络和 4G网络以及 更高级的网络制式的网络, 还可适用于 Wimax扁平化网络。 其中, 2G网络 可为 GSM网络, 3G网络可为 UMTS网络。
图 2A为本发明提供的传输资源过载处理方法实施例一流程图。 本实施 例的执行主体信令面控制实体为用于传输资源负载判决的指定的中心节点, 称为指定的信令面控制实体。 如图 2A所示, 本实施例包括:
步骤 21A: 指定的信令面控制实体获取基站控制设备流量消息和服务网 关流量消息; 基站控制设备流量消息包括基站控制设备各用户接口的发送流 量和接收流量的信息; 网关流量消息包括网关各用户接口的发送流量和接收 流量的信息。
用户面实体包括基站控制设备和网关。 用户接口为基站控制设备与网关 之间的接口。在 LTE网络中,基站控制设备可对应于 eNB中与传统基站控制 器的功能相近的模块,信令面控制实体可为 MME, 网关可为 S-GW, 用户接 口为 eNB和 S-GW之间的 S 1 -U接口;在 3 G网络中,基站控制设备可为 RNC, 信令面控制实体可为 MGW, 网关可为 SGSN, 用户接口可为 RNC和 SGSN 之间的 IuPS接口; 在 2G网络中, 基站控制设备可为 BSC,信令面控制实体 可为 MGW, 用户接口可为 BSC和 SGSN之间的 Gb接口。
基站控制设备接入信令面控制实体时, 称该基站控制设备归属该信令面 控制实体。 基站控制设备归属指定的信令面控制实体时, 该信令面控制实体 接收该基站控制设备发送的基站流量信息; 基站控制设备不归属信令面控制 实体时, 该信令面控制实体可以接收该基站控制设备归属的信令面控制实体 转发的该基站控制设备上报的基站控制设备流量信息; 基站控制设备归属多 个信令面控制实体时, 基站控制设备向归属的其中一个信令面控制实体上报 基站控制设备流量信息。 同理, 网关归属指定的信令面控制实体时, 指定的 信令面控制实体接收网关发送的网关流量消息; 网关不归属指定的信令面控 制实体时, 指定的信令面控制实体可以接收该网关归属的信令面控制实体转 发的该网关上报的网关流量消息。
步骤 22A: 指定的信令面控制实体根据基站控制设备流量消息和网关流 量消息, 向基站控制设备或网关发送用于调整用户流量指示信息, 或, 向基 站控制设备和 /或网关发送用于调整用户准入的指示消息。
该指示消息可以是针对用户准入进行调整的指示消息, 也可以是针对用 户流量进行调整的指示信息。
以 LTE网络为例,指定的 MME获取各 eNB的 eNB流量消息和各 S-GW 的 S-GW流量消息后。 指定的 MME根据各 eNB流量消息和各 S-GW流量 消息, 向各 eNB或 S-GW发送用于调整用户流量指示信息, 或, 向 eNB和 / 或 S-GW发送用于调整用户准入的指示消息。 其中, eNB流量消息包括 eNB 各 Sl-U接口的发送流量和接收流量; S-GW流量消息包括 S-GW各 S1-U接 口的发送流量和接收流量; eNB为接入 MME的 eNB; S-GW为与 eNB相连 的 S-GW。 eNB归属指定的 MME时, 指定的 MME接收该 eNB发送的基站 流量信息; eNB不归属指定的 MME时, 指定的 MME接收该 eNB归属的 MME转发的该 eNB流量信息。 S-GW归属指定的 MME时, 指定的 MME接 收该 S-GW发送的 S-GW流量消息; S-GW不归属指定的 MME时, 指定的 MME接收该 S-GW归属的 MME转发的 S-GW流量信息。
本发明提供的传输资源过载处理方法, 信令面控制实体根据基站控制设 备上报的基站控制设备侧各用户接口的流量信息和网关上报的网关侧各用户 接口的流量信息进行负载判决, 在传输资源过载时, 将根据判决结果生成的 指示信息发送给基站控制设备和网关, 使基站控制设备和网关根据指示信息 调整用户流量或用户准入, 提高了用户面实体之间的传输资源利用率。
图 2B为本发明提供的传输资源过载处理方法实施例二流程图。本实施例 的执行主体为用户面实体, 用户面实体可为基站控制设备, 也可为网关。 如 图 2B所示, 本实施例包括:
步骤 21B: 用户面实体统计本端各用户接口的下行发送流量和上行接收 流量。
用户接口为本端与另一用户面实体之间的接口,本端为基站控制设备时, 另一用户接口为网关; 本端为网关时, 所述另一用户接口为基站控制设备。 以 LTE网络为例, 本端为 eNB时, 另一用户面实体为 S-GW, 信令面实体为 MME; 以 3G网络为例, 本端为 RNC时, 另一用户面实体 SGSN, 信令面实 体为 GMSC; 以 2G网络为例, 本端为 BSC时, 另一面用户实体为 SGSN, 信令面实体为 GMSC。
流量测量粒度可以用户面实体(例如, LTE网络中的 eNB ) 为单位; 也 可以^载的业务为单位, 如对 QCI ( QoS Class Indication )业务类型等进行测 量, 从产品实现难易程度来看, 一种优选的方式为: 以用户面实体为单位进 行测量。
步骤 22B: 用户面实体向归属信令面控制实体发送包括本端各用户接口 的上行发送流量和下行接收流量的流量消息。 步骤 23B: 用户面实体根据归属信令面控制实体发送的用于调整用户流 量的指示消息, 调整指示消息中携带的用户接口的用户流量, 或, 根据归属 信令面控制实体发送的用于调整用户准入的指示消息, 调整用户准入。
用户面实体向归属信令面控制实体发送包括本端各用户接口的上行发送 流量和下行接收流量的流量消息后 , 由归属信令面控制实体转发给指定信令 面控制实体对用户面实体进行负载判决, 并将判决结果通过相应的归属信令 面控制实体转发给用户面实体。
以 LTE网络为例, eNB或 S-GW统计本端各 S 1 -U接口的下行发送流量 和上行接收流量后,向归属 MME发送包括本端各 S1-U接口的上行发送流量 和下行接收流量的流量信息。 eNB或 S-GW接收到由归属 MME转发的来自 指定 MME的用于调整用户流量或用户准入的指示消息后, ^^据指示信息调 整用户流量或用户准入。
本发明提供的传输资源过载处理方法, 用户面实体分别监测各自用户接 口的流量并向信令面控制实体上报, 在信令面控制实体根据上报的流量信息 确定传输资源过载时, 用户面实体根据信令面控制实体发送的指示信息调整 用户流量或用户准入, 提高了用户面实体之间的传输资源利用率。
在图 3A和图 4A对应实施例中 ,以 LTE网络中 eNB与 S-GW之间的 S 1 -U 接口为例说明本发明提供的传输资源过载处理方法。
图 3A为本发明提供的传输资源过载处理方法实施例三流程图。 图 3B为 本发明提供的一种应用场景图。如图 3B所示, 同一 eNB接入了同一个 MME 的不同 S-GW: S-GWa和 S-GWb。 eNB与 S-GWa之间的 SI -U接口标记为 S 1 -Ua接口, eNB与 S-GWb之间的 S 1 -U接口标记为 S 1 -Ub接口。 本实施例 以接入网中的一个 eNB为例, 说明 eNB与 S-GW间的传输资源过载时 MME 对用户准入的处理方法,接入网中其它 eNB的处理方法类似。如图 3A所示, 本实施例包括:
步骤 1: eNB和各 S-GW统计本端各 S1-U接口的发送流量和接收流量。 eNB统计 S 1 -Ua接口的发送流量和接收流量, 并统计 S 1 -Ub接口的发送 流量和接收流量。 同理, S-GWa (服务网关 a )统计 Sl-Ua接口的发送流量 和接收流量, 并统计 S-GWb (服务网关 b )统计 Sl-Ub接口的发送流量和接 收流量。 步骤 2: eNB和各 S-GW向归属 MME发送 Sl-U folw statistic Report消 自
eNB向归属 MME发送 Sl-U folw statistic Report消息, S-GWa向归属 MME发送 Sl-U folw statistic Report消息。 S-GWb向归属 MME发送 Sl-U folw statistic Report消息。
eNB发送的 Sl-U folw statistic Report消息中,携带有本端各 Sl-U接口的 发送流量和接收流量,还可以携带有基站该过载门限值。 S-GWa发送的 S1-U folw statistic Report消息中,携带有本端各 S1-U接口的发送流量和接收流量, 还可以携带有 S-GWa过载门限值。 S-GWb发送的 Sl-U folw statistic Report 消息中, 携带有本端各 Sl-U接口的发送流量和接收流量, 还可以携带有 S-GWb过载门限值。
步骤 3: MME统计 eNB所有 S1-U接口的传输流量, 并统计各 S-GW所 有 S1-U接口的传输流量。
MME将 eNB侧 S 1 -Ua接口的发送流量、 eNB侧 S 1 -Ua接口的接收流量, eNB Sl-Ub接口的发送流量和 eNB Sl-Ub接口的接收流量汇总后, 得到 eNB 所有 S1-U接口的传输流量。 MME将 S-GWa侧 Sl-Ula接口的发送流量和 S-GWa侧 Sl-Ula接口的接收流量汇总后, 得到 S-GWa所有 S1-U接口传输 流量。 MME按照同样的方法, 统计 S-GWb的传输流量。
另外, 步骤 1之后, 也可由 eNB和 S-GW统计各 S 1 -U接口的发送流量 和接收流量, 并分别向归属 MME上才艮。
步骤 4: MME判断 eNB的传输流量是否超过 eNB过载门限值, 并判断 各 S-GW的传输流量是否超过各 S-GW过载门限值。
MME判断基站的传输流量是否超过 eNB过载门限值,判断 S-GWa的传 输流量是否超过 S-GWa 过载门限值, 判断 S-GWb 的传输流量是否超过 S-GWb过载门限值。
步骤 5: MME根据判断结果, 向 eNB和各 S-GW发送调整用户准入的 Traffic adjustment indication消息。
步骤 6: eNB和各 S-GW根据 MME的调整用户流量的 Traffic adjustment indication消息, 调整用户准入。
在 eNB的传输流量超过该基站过载门限值时, MME确定 eNB过载; 在 一个 S-GW的传输流量超过该 S-GW的载门限值时, MME确定该 S-GW过 载。
eNB的传输流量超过该 eNB的过载门限值时, MME向与 eNB相连的且 传输流量没有超过自身过载门限值的 S-GW发送调整用户准入的 Traffic adjustment indication消息, 即 MME向与过载 eNB相连的轻载 S-GW发送调 整用户准入的 Traffic adjustment indication消息。 在此情况下, 轻载 S-GW接 收到调整用户准入的 "Traffic adjustment indication"消息后, 触发过载控制, 减 少与过载 eNB的信令连接, 降低用户的接入。
在一个 S-GW所有 S1-U接口的传输流量超过 S-GW过载门限值时, 若 eNB 没有超过该 eNB 的过载门限值, MME 向 eNB 发送调整用户准入的 "Traffic adjustment indication"消息, 同时将新准入的用户过载到轻载的 S-GW 上。 例如, S-GWa所有 S1-U接口的传输流量超过 S-GWa过载门限值, eNB 没有超过 eNB 过载门限值, MME 向 eNB 发送调整用户准入的 "Traffic adjustment indication"消息,同时将新准入的用户过载到其它轻载的 S-GW上。 在此情况下, eNB接收到 Traffic adjustment indication消息后,触发过载控制, 减少与过载 S-GWa的信令连接,减少用户的准入请求,从而降低用户的接入。
在一个 S-GW所有 S1-U接口的传输流量超过该 S-GW的过载门限值, 且该 S-GW相连的 eNB的所有 S1-U接口的传输流量超过该 eNB的过载门限 值时, MME 分别向过载 eNB 和该 S-GW 发送调整用户准入的 "Traffic adjustment indication"信息。 例如, S-GWa 所有 S1-U接口的传输流量超过 S-GWa的过载门限值,且 S-GWa相连的 eNB的所有 S1-U接口的传输流量超 过 eNB的过载门限值, MME分别向过载 eNB和过载 S-GWa发送调整用户 准入的 "Traffic adjustment indication"信息。 此情况下, eNB接收到 "Traffic adjustment indication"信息后, 与 MME同时发起上下行过载控制, 拒绝用户 接入。 该过载 S-GW接收到 "Traffic adjustment indication"信息后, 发起过载 控制, 减少与 eNB的信令连接, 拒绝用户接入。
在一个 S-GW所有 S1-U接口的传输流量没有超过该 S-GW的过载门限 值, 且与该 S-GW相连的 eNB的所有 S1-U接口的传输流量没有超过该 eNB 的过载门限值时, S-GW和 eNB传输资源均充足, MME不发送调整用户准 入的 "Traffic adjustment indication"信息, 允许新用户准入。 需要说明是, MME进行步骤 4中的判断后,可将步骤 4的判断结果发送 给各网元: S-GW和 eNB, 由各网元根据判断结果进行判决。
另外, 通过 eNB和 S-GW上报的流量信息, MME可获知传输链路带宽 变化导致的传输资源变化, MME获知各 S-GW的传输流量。 MME在分配 S-GW Pool( S-GW Pool中包括归属该 MME的所有 S-GW )中选择某个 S-GW 为用户服务时,可根据 S-GW和 eNB的传输流量来选择合适的 S-GW使用户 准入,从而选择有足够资源(包括传输资源 )的 S-GW为用户服务(例如 GBR 业务和 Non-GBR业务) 。 同时, 通过 S-GW上报的流量信息, MME可根据 S-GW实际传输资源利用情况,设置用户准入的最大带宽,避免 eNB与 S-GW 侧的传输资源过载。
本发明实施例提供的传输资源过载处理方法, MME根据基站和 S-GW上 报的流量信息, 确定基站的负载和 S-GW的负载, 并根据负载情况向基站或 S-GW发送调整用户准入的指示信息。基站接收到 MME的用于调整用户准入 的指示信息后, 根据指示信息的指示减少与 S-GW的信令连接, 降低用户的 接入或拒绝新用户接入,从而保证已接入用户的业务质量,提高 S1-U接口传 输资源利用率。同样, S-GW接收到 MME的用于调整用户准入的指示信息后, 根据指示信息的指示减少与 eNB的信令连接, 降低用户的接入。
图 3C为本发明提供的传输资源过载处理方法实施例四流程图。本实施例 提供了 eNB与 S-GW间的用户面的传输资源过载时对 S1-U接口流量的处理 方法。 本实施例的应用场景图参见图 3B所示。 如图 3C所示, 本实施例与图 3 A对应实施例的区别在于, 在步骤 2之后包括:
步骤 3: MME判断同一 S 1 -U接口在 eNB侧的发送流量是否大于在 S-GW 侧的接收流量,并判断同一 S1-U接口在 eNB侧的接收流量是否小于在 S-GW 侧的发送流量。
从 eNB发送的 Sl-U folw statistic Report消息和 S-GW发送的 Sl-U folw statistic Report消息中提取同一用户接口在 eNB侧的发送流量和在 S-GW侧的 接收流量, 并提取所述同一用户接口在基 eNB侧的接收流量和在 S-GW侧的 发送流量。
步骤 4: 根据上述判断结果, MME向 eNB或各 S-GW发送调整用户流 量的 Traffic adjustment indication消息。 步骤 5: eNB和各 S-GW根据 MME的调整用户流量的 Traffic adjustment indication消息, 调整相应 S 1 -U接口的用户流量。
同一 S1-U接口在 eNB侧的发送流量大于在 S-GW侧的接收流量时, MME确定上行链路过载, 向 eNB发送调整用户流量的 Traffic adjustment indication消息,通知 eNB减少该 S 1 -U接口的发送流量,降低发送速率。 eNB 接收到 Traffic adjustment indication消息, 调整该 S 1 -U接口发送流量, 降低 S1-U接口发送速率, 以降低 eNB的拥塞程度。
同一 S1-U接口在 eNB侧的接收流量小于在 S-GW侧的发送流量时, MME 确定下行链路过载, 向 S-GW发送调整用户流量的 Traffic adjustment indication 消息, 通知 S-GW减少该 S1-U接口的发送流量, 降低发送速率。 S-GW接收到 Traffic adjustment indication消息后, 调整该 S 1 -U接口发送流量, 降低 S 1 -U接 口发送速率降低 S-GW的过载程度。

步骤 3: MME2向 MME1分别转发 S-GWc的 Sl-U folw statistic Report 消息和 S-GWd以及 eNB2的 Sl-U folw statistic Report消息。
MME2中接入有一个或多个 eNB, 同样, MMEl中也有接入有一个或多 个 eNB时, MMEl会接收到多个 eNB的各 S1-U接口的接收流量和发送流量。
步骤 4: MME1统计各 eNB所有 S1-U接口的传输流量, 并统计各 S-GW 所有 S1-U接口的传输流量。
MME1统计 eNB 所有 S1-U接口的传输流量、 eNB2所有 S1-U接口的传 输流量, S-GWa所有 S1-U接口的传输流量、 S-GWb所有 S1-U接口的传输 流量、 S-GWc所有 S1-U接口的传输流量和 S-GWd所有 S1-U接口的传输流 量。
MME2中有可能接入一个或多个 eNB, 同样, MM1中也有可能接入一个 或多个 eNB。 MMEl统计不同 MME中每个 eNB的所有 S1-U接口的接收流 量和发送流量和不同 MME中每个 S-GW的所有 S1-U接口的接收流量和发送 流量。 以 eNBk为例, eNBk所有 S1-U接口的传输流量 Tk ( l<k<M )如公式 1: Tk - in (公式 1 )
以 S-GWk为例, S-GWk所有 Sl-U接口的传输流量 Sk ( l≤k≤N )如公式 2:

在公式 1和公式 2中, m表示 eNB编号, n表示 S-GW编号, d表示传 输方向 (d=0表示发送, d=l表示接收)。
步骤 5: MME1 判断每个基站的传输流量是否超过各自的过载门限值, 并判断每个 S-GW的传输流量是否超过各自的 S-GW过载门限值。
MME1 判断 eNB 的传输流量是否超过 eNB 过载门限值, MME1 判断 eNB2的传输流量是否超过 eNB2过载门限值, 判断 S-GWa的传输流量是否超 过 S-GWa过载门限值,判断 S-GWb的传输流量是否超过 S-GWb过载门限值, 判断 S-GWc的传输流量是否超过 S-GWc过载门限值,判断 S-GWd的传输流 量是否超过 S-GWd过载门限值。如果有多个基站, MME1分别判断每个 eNB 的传输流量是否超过各自的过载门限值。 其中, eNB的过载门限值和 S-GW 的过载门限值, 可分别从 eNB和 S-GW上报的 "Sl-U folw statistic Report"消 息中获取。
步骤 6: 根据判断结果, MME1向归属的 eNB和 S-GW发送调整用户准 入的 Traffic adjustment indication消息, 并向 MME2发送归属 MME2的 eNB 和 S-GW的调整用户准入的 Traffic adjustment indication消息。
步骤 7: MME2向归属 MME2的 eNB和 S-GW转发调整用户准入的 Traffic adjustment indication消息。
MMEl向归属的 eNB和归属的 S-GW发送 Traffic adjustment indication 消息。对于归属 MME2的 eNB和 S-GW,将 Traffic adjustment indication消息 发送给 MME2, 由 MME2转发给归属的 eNB和 S-GW。 例如, MME1根据 判断结果,向 eNB S-GWa或 S-GWb发送调整用户准入的 Traffic adjustment indication消息。 MMEl根据判断结果,向 MME2发送 eNB2、 S-GWc或 S-GWd 调整用户准入的 Traffic adjustment indication消息。由 MME2向 eNB2、 S-GWc 或 S-GWd转发调整用户准入的 Traffic adjustment indication消息。
步骤 8: 各 eNB 和各 S-GW根据 MME1 的调整用户流量的 Traffic adjustment indication消息, 调整用户准入。
在一个 eNB的传输流量超过该 eNB的过载门限值时, MME1确定该 eNB 过载; 在一个 S-GW的传输流量超过该 S-GW的载门限值时, MME1确定该 S-GW过载。
一个 eNB的传输流量超过该 eNB的过载门限值时, MME1向与该 eNB 相连的且传输流量没有超过自身过载门限值的 S-GW发送调整用户准入的 Traffic adjustment indication消息, 即 MME 1向与过载 eNB相连的轻载 S-GW 发送调整用户准入的 Traffic adjustment indication消息。 例如, eNBi的传输流 量超过 eNBi的过载门限值时, MME1向与 eNBi相连的且传输流量没有超过 自身过载门限值的 S-GW发送调整用户准入的 Traffic adjustment indication消 息。 在此情况下, 轻载 S-GW接收到调整用户准入的 "Traffic adjustment indication"消息后, 触发过载控制, 减少与过载 eNB 的信令连接, 降低用户 的接入。
在一个 S-GW所有 S1-U接口的传输流量超过该 S-GW的过载门限值时, MME1向与该 S-GW相连的且传输流量没有超过自身过载门限值的 eNB发送 调整用户准入的 "Traffic adjustment indication"消息,即 MMEl向与过载 S-GW 相连的轻载 eNB发送调整用户准入的 "Traffic adjustment indication"消息, 同 时将新准入的用户过载到轻载的 S-GW上。 例如, S-GWa所有 S1-U接口的 传输流量超过 S-GWa过载门限值, eNB 没有超过 eNB过载门限值, MME1 向 eNB发送调整用户准入的 "Traffic adjustment indication"消息, 同时将新准 入的用户过载到其它轻载的 S-GW上。 在此情况下, eNB 接收到 Traffic adjustment indication消息后,触发过载控制,减少与过载 S-GWa的信令连接, 降低用户的接入。
在一个 S-GW所有 S1-U接口的传输流量超过该 S-GW的过载门限值, 且该 S-GW相连的 eNB的所有 S1-U接口的传输流量超过该 eNB的过载门限 值时 , MME1 分别向该 eNB 和该 S-GW 发送调整用户准入的 "Traffic adjustment indication"信息。 例如, S-GWa 所有 S1-U接口的传输流量超过 S-GWa过载门限值, 且 S-GWa相连的 eNB 的所有 S1-U接口的传输流量超 过 eNB 的过载门限值, MME1分别向 eNB 和 S-GWa发送调整用户准入的 "Traffic adjustment indication"信息。此情况下, eNBi接收到 "Traffic adjustment indication"信息后, 与 MME1 同时发起上下行过载控制, 降低用户接入。 S-GWa接收到 "Traffic adjustment indication"信息后, 发起过载控制, 减少与 eNB 的信令连接, 降低用户接入。
在一个 S-GW所有 S1-U接口的传输流量没有超过该 S-GW的过载门限 值, 且与该 S-GW相连的 eNB的所有 S1-U接口的传输流量没有超过 eNB的 过载门限值时, S-GW和 eNB传输资源均充足, MME1不发送调整用户准入 的" Traffic adjustment indication"信息, 允许新用户准入。
需要说明是, MME1进行步骤 5中的判断后, 可将步骤 5的判断结果发 送给各网元: S-GW和 eNB, 由各网元根据判断结果进行与步骤 6类似的判 决。
本实施例提供的 eNB与 S-GW之间的传输资源过载处理方法, 归属不同 MME的各 eNB和各 S-GW分别监控本端 S 1 -U接口的流量, 并通过 eNB和 MME信令交互、 S-GW与 MME信令交互, 将流量信息汇聚到指定 MME处 进行负载判决, 再由 MME1 将调整用户准入的指示信息分别知会 eNB 与 S-GW, 各 eNB与 S-GW根据指定 MME分发的指示信息进行过载处理。
图 4C为本发明提供的传输资源过载处理方法实施例六流程图。本实施例 提供了基站与 S-GW间的用户面的传输资源过载时 MME对用户面流量的调 整方法。 本实施例的应用场景参见图 4B所示。 如图 4C所示, 本实施例与图 4A对应实施例的区别在于, 在步骤 3之后, 还包括:
步骤 4: MME1 判断同一 S1-U接口在 eNB侧的发送流量是否大于在 S-GW侧的接收流量, 并判断所述 S1-U接口在 eNB侧的接收流量是否等于 在 S-GW侧的发送流量。
步骤 5: 根据上述判断结果, MME1分别向 eNB S-GWa或 S-GWb发 送调整用户流量的 Traffic adjustment indication消息, 并向 MME2发送归属 MME2 的各 eNB 和 /或各 S-GW发送调整用户流量的 Traffic adjustment indication消息。
MME1根据判断结果, 分别向 eNB S-GWa和 S-GWb发送调整用户流 量的 Traffic adjustment indication消息。 MME1根据判断结果, 向 MME2发送 eNB2、 S-GWc和 S-GWd调整流量的 Traffic adjustment indication消息。
步骤 6: MME2 向 eNB2、 S-GWc 和 S-GWd转发调整流量的 Traffic adjustment indication消息。
步骤 7: 各 eNB 和各 S-GW根据 MME1 的调整用户流量的 Traffic adjustment indication消息, 调整相应 S 1 -U接口的用户流量。
以其中一个接入多个 ΜΜΕ的不同 S-GW的 eNBm为例, eNBm的 S 1 -U^ 接口的发送流量与 8-0\\^侧 Sl-U^接口的接收流量相等、 并且 eNBm侧 S l-U^接口的接收流量与 S-GW侧 S l-U^接口的发送流量相等时,也就是: Lmn0
Figure imgf000021_0001
S1-I 接口的下行链路和上行链路均正常。 此时, MME1向 eNBm发送包括' 'Increase the traffic of S l-U sending direction"和 S l-Umn接口号的 Traffic adjustment indication消息, 同时 MME1也向 S-GWn 发送包括' 'Increase the traffic of Sl-U sending direction" 的 Traffic adjustment indication消息。 "Increase the traffic of Sl-U sending direction"指示 eNBm和 S-GWn分别增加在 S l-U^接口的发送流量,但发送流量不能超过允许发送的 最大流量。
eNBm的 S l-Umn接口的发送流量大于 S-GW^ Sl-Umn接口的接收流 量,也就是: LmnO>Rmnl , MME1确定 Sl-Umn接口的上行链路过载,向 eNBm 发送包括" Reduce the traffic of Sl-U sending direction" 和 S l-U 接口号的 Traffic adjustment indication消息, 指示 eNBm减少 SI -Umn接口的发送流量, 降低发送速率。 eNBm接收到 Traffic adjustment indication消息,减少与 S-GWn 关联的 S 1 -Umn接口发送流量, 降低该 S 1 -Umn接口发送速率, 以减少 eNBm 的拥塞程度。
eNBm的 S l-Umn接口的接收流量小于 S-GW ^S l-Umn接口的发送流量, 也就是: Lmn RmnO, MME1确定 S I -Umn接口下行链路过载, 向 8-0\\^发送 包括" Reduce the traffic of Sl-U sending direction" 和 Sl-U腿接口号的 Traffic adjustment indication消息, 通知 S-GWn减少在 SI -Umn接口的发送流量, 降低 发送速率。 S-GW接收到 Traffic adjustment indication消息后, 减少与 eNBm关联 的 S 1-U接口发送流量, 降低该 Sl-Umn接口发送速率, 以降低 S-GW的过载程 度。
对于 S 1 -U接口发送流量的调整, 可以通过上行反压的方式即传输网络层 调整无线网络层下发的流量; 也可通过调整传输的緩存, 对发送的流量进行 流量整型调整传输数据的发送。
需要说明是, MME1进行步骤 4中的判断后, 可将步骤 4的判断结果发送 给各网元: S-GW和 eNB , 由各网元根据判断结果进行决策。 本实施例 MME1 对 Sl-U接口流量集中监控,分别对各 eNB与各 S-GW两侧的 Sl-U流量状况进行 评估并下发相应调整命令, 以提高 eNB与 S-GW的传输资源利用率。
