Description

拥塞控制方法、 移动管理网元及设备 技术领域
本发明涉及通信领域, 尤其涉及一种拥塞控制方法、 移动管理网元及设备。 背景技术
随着物联网 ( Machine To Machine, M2M ) 的快速发展, M2M已成为各个 标准化组织研究和标准制定的工作重点。 第三代合作伙伴计划 (The 3rd Generation Partnership Project, 3GPP )作为移动通信技术的主要研究和标准制定 者, 对 M2M的相关研究和标准制定也在加紧进行。
未来, 物联网中机器类型通信(Machine Type Communication, MTC ) 终 端的数量与传统终端相比, 将呈几何数量级的增长。 虽然这些 MTC终端可能相 对静止且产生的业务数据流量也比较少,但是每个 MTC终端却产生与传统终端 几乎相同的信令数量, 因此, 当将来大量的 MTC终端与网络进行信令交互时, 势必会对网络产生巨大的沖击, 致使网络产生过载和拥塞。 为了应对这一变化, 3GPP 启动了关于机器类型通信网络增强 ( Network Improvements for Machine-Type Communications, NIMTC )项目来深入研究 MTC通信对 3GPP网 络的影响及网络实现 MTC通信的优化方案。
3GPP对 MTC引起的网络过载和拥塞进行了研究, 目前 3GPP定义的对于 移动管理网元侧的拥塞控制机制主要包括:非接入层( Non-Access Stratum, NAS ) 接口的拥塞控制和 GPRS隧道协议( GPRS Tunneling Protocol, GTP )接口的拥 塞控制。
对于 NAS接口的拥塞控制, 3GPP引入了推迟定时器(Back-off timer )机 制来限制来自于用户设备(User Equipment, UE ) 的信令; 其具体思想是:
( 1 )、 移动管理网元进行拥塞控制时, 拒绝来自于 UE的 NAS信令请求, 并在拒绝消息里指示网络侧拥塞并携带一个 Back-off timer值;
( 2 )、 UE在收到携带有拥塞指示的拒绝消息后, 根据收到的 Back-off timer 值, 启动对应的 Back-off timer;
( 3 )、 在 Back-off timer超时之前, UE不会向移动管理网元发起 NAS信令 请求。 对于 GTP接口的拥塞控制, 3GPP引入了阀控(Throttling )机制来限制来 自于服务网关(Serving Gate Way, S-GW ) 的信令; 其具体实现思想为:
( 1 )、 MME进行拥塞控制时,对于来自于 S-GW的下行数据通知( Downlink Data Notification, DDN )消息, 根据 DDN消息中指示的承载优先级判断是否是 低优先级业务。
( 2 )、若是低优先级业务, 则 MME拒绝 DDN消息, 并在向 S-GW的 DDN 应答消息中携带阀控系数 ( Throttling Factor )与阀控时间 ( Throttling Delay )信
( 3 )、 后续 S-GW在收到下行业务数据时, 对于低优先级业务根据阀控系 数与阀控时间决定是否发起 DDN消息到移动管理网元。
另夕卜, 在支持 SGs接口的演进分组系统( Evolved Packet System, EPS ) 网 络或支持 Gs接口的传统 2G、 3G网络, 移动交换中心 (Mobile-services Switching Centre, MSC)/拜访位置寄存器( Visitors Location Register, VLR )在收到下行的 电路交换 ( Circuit Switched, CS )语音呼叫或短消息时, 会通过 SGs或 Gs接口 向移动管理网元发起寻呼并触发移动管理网元发起到 UE的空口寻呼。 因此, 当 移动管理网元由于在分组交换( Packet Switched, PS )业务拥塞时,由于 MSC/VLR 并不知道移动管理网元拥塞了,则 MSC/VLR仍然会通过 SGs或 Gs接口向移动 管理网元发起寻呼, 这必然会增加移动管理网元的信令负荷, 导致拥塞恶化。 但是, 目前 3GPP标准里, 还未在 SGs或 Gs接口引入拥塞控制机制, 这增加了 移动管理网元拥塞恶化的风险。 发明内容

下面结合附图对本发明的具体实施方式进行说明。
下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案进行清 楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是 全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有做出创造 性劳动前提下所获得的所有其他实施例, 都属于本发明保护的范围。
在本发明实施例中, 用户设备(User Equipment, 筒称 UE )可以为以下任 意一种, 并且 UE可以是静态的, 也可以是移动的。 静止的 UE可以包括为终端
( Terminal )、移动台( Mobile Station )、用户单元( Subscriber Unit )或站台( Station ) 等。 移动的 UE可以包括蜂窝电话(Cellular Phone )、 个人数字助理(Personal Digital Assistant, PDA ), 无线调制解调器( modem ), 无线通信设备、 手持设备
( handheld ), 膝上型电月 ( Laptop Computer ), 无绳电话 ( Cordless Phone )或 无线本地环路(Wireless Local Loop, WLL ) 台等。 上述 UE可以分布于整个无 线网络中。
为了便于本领域技术人员的理解, 下面以具体的应用实例来说明。 需要说 明的是, 在本发明实施例中, 移动管理网元可以为移动管理实体 ( Mobility Management Entity, MME)或月良务 GPRS支持节点( Serving GPRS Support Node, SGSN ) 中的任一种, MSC与 VLR通常合设为同一网元, 称为 MSC/VLR, 或 筒称为 VLR。
首先结合图 1至图 9, 对移动管理网元被动地进行拥塞控制时, 移动管理网 元和 MSC/VLR的工作方式进行说明。需要说明的是,在图 1至图 9所提供的实 施例中,移动管理网元在接收到来自 MSC/VLR的寻呼请求后所回复的寻呼响应 消息, 其作用是对所接收到的寻呼请求进行响应, 该寻呼响应消息可以是寻呼 拒绝消息, 也可以是用户设备不可达消息, 还可以是业务请求消息。
请参考图 1 , 是本发明实施例提供的一种拥塞控制方法的流程示意图; 图 1 所示实施例对移动管理网元所执行的拥塞控制方法进行说明, 其主要是当移动 管理网元处于拥塞状态时,若接收到来自 MSC/VLR的寻呼请求,则回复寻呼响 应消息,并指示 MSC/VLR对需要发给所述移动管理网元的寻呼请求进行拥塞控 制。 图 1所示实施例的拥塞控制方法包括:
步骤 S11 , 移动管理网元接收来自 MSC/VLR的寻呼请求。
其中, 当移动管理网元是 MME时, 该寻呼请求为 SGs寻呼请求。 当移动 管理网元是 SGSN时, 该寻呼请求为 Gs寻呼请求。
MSC/VLR通常会向移动管理网元发送寻呼请求的情况是: 当 UE发起联合 注册流程并在移动管理网元和 MSC/VLR上成功联合注册后,若 MSC/VLR收到 下行的语音呼叫或短消息时,会通过 SGs接口或者 Gs接口向移动管理网元发起 寻呼请求, 以触发移动管理网元发起到 UE的空口寻呼。 需要说明的是, UE发 起联合注册时, 能够注册成功的前提条件是: 此时移动管理网元并未处于拥塞 状态。
步骤 S12, 如果移动管理网元处于拥塞状态, 则向 MSC/VLR返回携带拥塞 控制信息的寻呼响应消息,所述拥塞控制信息用于指示 MSC/VLR对需要发给移 动管理网元的寻呼请求进行拥塞控制。
其中, 可以预先在移动管理网元上配置拥塞检测机制, 根据运营商配置的 拥塞条件实时检测移动管理网元是否处于拥塞状态; 当移动管理网元进入拥塞 状态后, 该拥塞检测机制继续运行, 并在检测到拥塞不存在时, 移动管理网元 离开拥塞状态。
当处于拥塞状态的移动管理网元接收到来自 MSC/VLR的寻呼请求时,由于 移动管理网元已拥塞, 为了避免移动管理网元的拥塞恶化, 移动管理网元向 MSC/VLR返回寻呼响应消息, 并在寻呼响应消息中携带拥塞控制信息。 实际应 用中, 可以预先在移动管理网元中配置拥塞控制策略, 例如: 该拥塞控制策略 可配置为向所有的 MSC/VLR 发送寻呼响应消息, 或者, 可配置为向部分 MSC/VLR发送寻呼响应消息; 移动管理网元可以根据预先配置的拥塞控制策略 选择向全部或部分 MSC/VLR发送寻呼响应消息。
具体地, 移动管理网元在寻呼响应消息中携带的拥塞控制信息可以按照运 营商配置在其上的拥塞控制策略确定, 下面将对本发明提供的寻呼响应消息中 携带的拥塞控制信息的几种实施方式进行详细阐述, 可以理解的是, 下述的实 施方式仅为举例, 本发明提供的拥塞控制信息并不限于下述所描述的实施方式。 需要说明的是, 下述对拥塞控制信息包括的内容的阐释和说明同样适用于本发 明的其它实施例。
在本发明提供的拥塞控制信息的第一种实施方式中, 拥塞控制信息可以包 括: 第一推迟定时器值(Back-off timer value ), 用于指示 MSC/VLR启动推迟定 时器, 并将推迟定时器的定时值设置为该第一推迟定时器值, MSC/VLR在推迟 定时器超时之前,停止向所述移动管理网元发送寻呼请求, 即 MSC/VLR在推迟 定时器超时之前, 不会向移动管理网元发送寻呼请求。
在本发明提供的拥塞控制信息的第二种实施方式中, 拥塞控制信息可以包 动管理网元的状态设置为拥塞状态,并指示所述 MSC/VLR启动推迟定时器,在 推迟定时器超时之前, 保持所述移动管理网元的状态为拥塞状态, 并停止向所 述移动管理网元发送寻呼请求, 即 MSC/VLR在推迟定时器超时之前,不会向移 动管理网元发送寻呼请求。 所述推迟定时器的定时值可以被设置为默认值, 例 如: 默认值为第一拥塞原因对应的值。 需要说明的是, 一种拥塞原因对应于一 种默认值, 不同的拥塞原因可以对应相同的默认值, 也可以对应不同的默认值。
在本发明提供的拥塞控制信息的第三种实施方式中, 拥塞控制信息可以包 括: 第二拥塞原因和第二推迟定时器值; 所述第二拥塞原因, 用于指示所述 MSC/VLR将与所述 MSC/VLR 关联的所述移动管理网元的状态设置为拥塞状 态; 所述第二推迟定时器值, 用于指示所述 MSC/VLR启动推迟定时器, 并将所 述推迟定时器的定时值设置为所述第二推迟定时器值, 在所述推迟定时器超时 之前, 保持所述移动管理网元的状态为拥塞状态, 并停止向所述移动管理网元 发送寻呼请求, 即 MSC/VLR在推迟定时器超时之前,不会向移动管理网元发送 寻呼请求。

当接收单元 201接收到来自 MSC/VLR的寻呼请求时,如果此时移动管理网 元处于拥塞状态,为了避免移动管理网元的拥塞恶化,处理单元 202向 MSC/VLR 返回寻呼响应消息, 并在寻呼响应消息中携带拥塞控制信息。 实际应用中, 可 以预先在移动管理网元中配置拥塞控制策略, 例如: 该拥塞控制策略可配置为 向所有的 MSC/VLR发送寻呼响应消息, 或者, 可配置为向部分 MSC/VLR发送 寻呼响应消息; 处理单元 202可以根据预先配置的拥塞控制策略选择向全部或 部分 MSC/VLR发送寻呼响应消息。
其中, 寻呼响应消息可以为寻呼拒绝消息, 也可以为用户设备不可达消息, 还可以为业务请求消息。
具体地, 携带在寻呼响应消息中的拥塞控制信息可以按照运营商配置在其 上的拥塞控制策略确定, 该拥塞控制信息的具体实施方式可以参见图 1 所示实 施例中关于拥塞控制信息的实施方式的描述, 在此不赘述。

其中,寻呼响应消息中所携带的拥塞控制信息的具体实施方式可以参见图 1 所示实施例中的说明, 在此不再赞述。
处理单元 213, 用于根据拥塞控制信息, 对需要发给移动管理网元的寻呼请 求进行拥塞控制。
针对不同实施方式的拥塞控制信息, 处理单元 213 所执行的拥塞控制也可 能存在多种实施方式, 所述处理单元 213的具体处理方式可以参见图 2所示实 施例中关于 MSC/VLR所执行的拥塞控制的实施方式的说明, 在此不赘述。
可选地, 所述处理单元 213, 还用于在执行对需要发给所述移动管理网元的 寻呼请求进行拥塞控制时, 通过 A/Iu接口直接向用户设备发起寻呼请求。
本实施例中, MSC/VLR向移动管理网元发送寻呼请求后, 如果接收到移动 管理网元的寻呼响应消息, 表明移动管理网元当前处于拥塞状态, MSC/VLR则 根据寻呼响应消息中的拥塞控制信息对需要发给移动管理网元的寻呼请求进行 拥塞控制,通过 MSC/VLR与移动管理网元的此种交互,可减少处于拥塞状态的 移动管理网元接收的请求消息的数量, 降低移动管理网元拥塞恶化的风险, 有 助于移动管理网元的业务恢复, 保障上下行业务的顺利进行。 请参考图 22, 是本发明实施例提供的另一种移动管理网元的结构示意图。 该移动管理网元包括: 监测单元 221和处理单元 222。

如果接收单元 231 只接收到来自移动管理网元的拥塞开始消息, 此种情况 下, 本实施例存在以下一种可行的实施方式:
在本实施例的一种可行的实施方式中, 所述拥塞开始消息中携带拥塞控制 信息, 该拥塞控制信息可以包括: 第一推迟定时器值或第一拥塞原因; 或者, 包括第一推迟定时器值, 同时包括第一阀控粒度、 第一阀控类型和第一阀控系 数中的至少一项; 或者, 包括第一拥塞原因, 同时包括第一阀控粒度、 第一阀 控类型和第一阀控系数中的至少一项。 处理单元 232根据拥塞开始消息可以获 取与所述 MSC/VLR相关联的移动管理网元处于拥塞状态,并根据拥塞开始消息 中携带的拥塞控制信息执行拥塞控制。 需要说明的是, 针对拥塞控制信息存在 的上述各种实施方式, 处理单元 232在该拥塞控制信息的指示下对需要发给移 动管理网元的寻呼请求所执行的拥塞控制的实施方式具体可以参见图 所示实 施例中关于 MSC/VLR执行的拥塞控制的相关说明, 在此不赘述。
如果接收单元 231接收到来自移动管理网元的拥塞开始消息和拥塞停止消 息, 此种情况下, 本实施例存在以下两种可行的实施方式:
在第一种可行的实施方式中, 所述接收单元 231接收到来自移动管理网元 的拥塞开始消息中没有携带拥塞控制信息, 所述处理单元 232接收到拥塞开始 消息则可获知所述移动管理网元处于拥塞状态, 从而对需要发给所述移动管理 网元的寻呼请求进行拥塞控制。 在接收到所述拥塞停止消息时, 所述处理单元 232获知所述移动管理网元离开拥塞状态,则停止对需要发给所述移动管理网元 的寻呼请求进行拥塞控制。

需要说明的是, 所述处理单元 232还可以用于在执行对需要发给所述移动 管理网元的寻呼请求进行拥塞控制时,通过 A/Iu接口直接向 UE发起寻呼请求。
本实施例由进入拥塞状态的移动管理网元通过拥塞开始消息主动指示与其 关联的全部或部分 MSC/VLR 进行拥塞控制, 并可通过拥塞停止消息指示 MSC/VLR停止拥塞控制。 通过 MSC/VLR与移动管理网元的此种交互, 可减少 处于拥塞状态的移动管理网元接收的请求消息的数量, 降低移动管理网元拥塞 恶化的风险, 有助于移动管理网元的业务恢复, 保障上下行业务的顺利进行。
