本发明有益效果如下:
本发明实施例提供的技术方案中, 在实施时, 对于 MME—侧, MME在 复位后, 接收到 S-GW发送的 Paging Notification消息时, 便向 eNodeB发送 包含自身 MME标识的 Paging消息。 对于 eNodeB—侧,在 eNodeB确定 Paging 消息包含 MME标识时, eNodeB向 UE发送包含 MME标识的 Paging消息。 对于 UE—侧, UE在确定 Paging消息包含 MME标识时, UE确定该发起寻 呼的 MME标识与 UE所注册的 MME标识是否一致; 若一致, UE响应该 Paging消息, 若不一致, UE不响应该 Paging消息。
由于 MME在复位后便在寻呼消息中指示 MME的标识信息, eNodeB向 UE发送 Paging消息时也包含了该 MME的标识, 这样 UE便能够根据该标识 确定是否响应 , 从而能够在 MME复位情况下有效解决 UE重复发起网络附着 请求的问题,避免 UE重复发起网络附着请求。 该方案对现有协议规程修改较 小, 易于实现, 能够较好的保持网络系统间的兼容性。 附图说明

在 EPS系统中, 由于故障或掉电等原因核心网管理控制实体 MME可能 发生失效, 这样 MME将丟失先前所维护的、 管理的所有 UE的上下文信息。 根据现有通用分组无线业务( General Packet Radio Service, GPRS ) 隧道协议 ( GPRS Tunnel Protocol, GTP )操作流程, S-GW通过 GTP回响( GTP Echo ) 消息在检测到 MME失效之后 ,它将删除本地维护的与失效 MME相关的所有 UE的承载信息, 从而对用户的演进分组核心网 (Evolved Packet Core, EPC ) 服务造成不利影响。
在 MME重新复位之后 ,按照现有协议 UE可以通过跟踪区更新( Tracking Area Update, TAU )及 UE触发服务请求( UE Triggered Service Request )等 过程在网络侧节点 (如 MME, S-GW ) 重新建立上下文信息, 图 1 为 MME 失效复位后 TAU及上行业务处理流程示意图, 该操作的主要流程大致如图 1 所示。在此过程中,由于复位后的 MME丟失了用户的上下文信息,UE的 TAU 或服务请求( Service Request )将被拒绝。这将触发 UE再次发起附着( Attach ) 过程, 从而在网络侧重新建立起用户的上下文信息。
从用户体验角度来看, 对于处于空闲 (IDLE ) 态的 UE而言, 如果它在 MME失效至恢复的整个过程中始终处于 IDLE状态, 那么移动性管理或周期 性触发的 TAU过程将使 UE对 MME的失效及恢复过程毫无察觉,因此 MME 的失效对用户业务不造成任何影响。对于 MME恢复之后有上行业务需要传输 的 UE而言, 当用户的上行数据到达时,它将发起 Service Request过程。此时, 虽然用户首次发起的服务请求将被网络拒绝, 但是在自动触发的 Attach过程 完成之后, 用户便可再次发起服务请求过程来请求网络的服务, 因此 MME 失效对用户上行业务体验也不会造成太大影响。
然而,在 MME复位之后 ,对于到达的下行业务数据而言情况就完全不同。 图 2为 MME失效复位后下行业务处理流程示意图, 如图 2所示, 由于 MME 发生重启, S-GW将删除本地维护的与失效 MME相关的所有用户上下文信息 , 而此时到达网络的下行业务数据也将被 S-GW拒绝。 在此情况下, 下行数据 处理过程无法触发网络重新建立用户的上下文信息, 这将造成下行业务数据 不能到达终端, 从而给用户体验带来严重的负面影响。
为了确保用户的 EPC业务体验在任何情况下都不受影响, 有如下方案用 于在 MME复位后恢复 UE的上下文信息:
1、在会话建立及修改过程中, MME将 UE最新的 TA list发送给 S-GW。
2、 当 MME失效时 , S-GW临时性的保存与失效 MME相关的所有 UE 的 IMSI及 TA list信息, 释放 UE的其他上下文信息及资源, 并通知分组数据 网网关( Packet Data Network Gateway, P-GW )清除所维护的 UE上下文信息。
3、 当 MME复位时, S-GW通过寻呼通知(Paging Notification ) 消息将 所保存的与该 MME相关的所有 UE的 [IMSI, TA list]信息发送给 MME。
4、 当接收到包含 [IMSI, TA list]信息的 Paging Notification消息时, MME 在 TA list包含的 TA中发起指示 IMSI的寻呼( Paging )过程。
5、 当接收到指示 IMSI的 Paging消息时, UE按照 3GPP TS 24.301协议 规范发起 Attach过程。
图 3为改进后的 MME复位处理机制实施流程示意图,上述操作的主要流 程可以参见图 3所示。
图 4为 Paging过程示意图, 在 EPS系统中, 指示 IMSI的 Paging过程如 图 4所示。 在需要对 UE进行寻呼时, MME首先通过 S1接口将 Paging消息 通知给演进基站 ( eNodeB ), 之后由 eNodeB通过空中接口信令在各个小区内 对 UE发起寻呼。这里对每个节点处的具体细节不做展开,详细步骤请参考较 新版本的 3GPP TS 24.301。
对于 S1接口 Paging消息格式, 在 S1接口上, MME使用 S1接口应用协 议( SI -Application Protocol, S1-AP )协议与 eNodeB进行交互, MME发送至 eNodeB的 Paging消息格式如下表所示,具体描述请参考较新版本的 3GPP TS
36.413。

对于 LTE-Uu接口 Paging消息格式, 在 LTE-Uu接口上, eNodeB发送至 UE的空中接口无线资源控制 (Radio Resource Control, RRC )信令中 Paging 消息的格式如下所示, 具体描述请参考较新版本的 3GPP TS 36.331。

对于全球唯一(用户) 临时标识 ( Globally Unique Temporary Identity, GUTI )结构, EPS系统核心网管理控制实体 MME为 UE分配的 GUTI具有 如下结构:
<GUTI> = <GUMMEI><M-TMSI> ,
其中 <GUMMEI> = <MCC><MNC><MME Identified,
<MME Identified = <MME Group IDxMME Code>。
上述参数的具体说明请参考较新版本的 3GPP TS 23.003。
对于 MME标识结构 , 在 EPS系统中, MME具有全球唯一的标识——全 球唯一 MME标识( Globally Unique MME Identifier, GUMMEI ),其结构如下:
<GUMMEI> = <MCC><MNC><MME Identifier ,
其中 <MME Identified = <MME Group IDxMME Code> 上述参数的具体说明请参考较新版本的 3GPP TS 23.003。
图 5为 UE再次附着发生过程示意图, 釆用 S-GW保存 UE的 IMSI标识 及 TA list并在 MME复位后触发 MME发起指示 IMSI的 Paging过程的机制 , 上述方案能够在失效恢复后的 MME处有效地建立起原始用户的上下文信息, 进而确保较高质量的用户体验。 然而, 上述方案存在重复发起指示 IMSI 的 Paging过程而造成 UE再次附着的风险, 具体发生过程请参见图 5所示。 如图 5所示,在 MME失效之后,网络中处于 IDLE态的 UE可能在 MME 复位之前向网络发起 TAU或 Service Request过程。 此时, 由于 MME正处于 失效状态, UE的请求将得不到网络响应。 对于用户而言, 在无法获得网络服 务情况下, 很可能的一种做法是重新启动 UE。 这样 UE将发起 Attach过程并 附着至一个正常工作的新的 MME来使用网络提供的通信服务。然而, 当旧的 MME从失效状态恢复之后, 按照上述方案, 它将根据 S-GW通过 Paging Notification消息提供的信息对 UE发起指示 IMSI的 Paging过程。 这将促使 UE进行本地去附着过程并再次触发 UE发起 Attach过程, 而这也将给用户体 验造成不利影响。
鉴于在 EPS系统中,在 UE在原有 MME失效期间已附着至新 MME的情 况下会导致 UE重复发起附着过程而给用户体验造成不利影响。为此,本发明 实施例中将基于寻呼指示的原理提出一种能够有效避免 UE重复发起 Attach 过程的优化方案。 下面结合附图对本发明的具体实施方式进行说明。
在说明过程中 , 将分别在从 MME侧、 eNodeB侧与 UE侧的实施进行说 明后, 再介绍三者的配合实施, 但这并不意味着三者必须配合实施, 实际上, 当三者分开实施时, 其也各自解决 MME侧、 eNodeB侧与 UE侧的问题, 只 是三者结合使用时, 会获得更好的技术效果。
图 6为 MME侧实施的 UE的寻呼处理方法流程示意图, 如图 6所示, 在 进行寻呼处理时可以包括如下步骤:
步骤 601、 MME复位;
步骤 602、 MME接收 S-GW发送的 Paging Notification消息;
步骤 603、 MME向 eNodeB发送包含自身 MME标识的 Paging消息。 实施中 , MME从失效状态复位之后 , MME在收到 S-GW提供的终端 IMSI 及 TA list信息后 , 向 UE发起寻呼时 , MME可以通过在寻呼消息中增加信息 单元以指示 MME标识的方式使 UE获知发起寻呼的 MME , 进而达到避免重 复发起 Attach过程的目的。
实施中, 向 eNodeB发送的 Paging消息可以是 S1-AP协议的 Paging消 息。
具体的, Paging消息是 S 1 -AP协议的 Paging消息时, MME标识为 Paging 消息中的条件可选项(C )或可选项(0 ); 当 MME因故障恢复而发起 Paging 消息时, Paging消息中包含 MME标识。 即 MME的标识可以以条件可选项或 可选项设置在 Paging 消息中, 设置的条件是: MME 因故障恢复而发起的 Paging。
下面以实例进行说明。
在 EPS 系统中, 在实施时可以在现有 S1-AP协议的 Paging消息中增加 MME的标识, 具体如下:
S1接口方面, 在 S1-AP协议的 Paging消息中增加 MME标识信息。 修改 后的 Paging消息格式如下表所示。 这里, 所增加的 IE "MME Identity" 用于 记录发起 Paging过程的 MME的标识, 表中以加粗部分示出。 根据网络部署 情况的不同, 在实际使用时, Paging消息中表示 MME标识的信息可以为: GUMMEI, MME标识( MME Identifier, MMEI ), MME码( MME Code, MMEC )等。 例如, "MME Identity" IE可做为条件可选项出现在 Paging消息 中, 出现的条件是: MME因故障恢复而发起的 Paging。

步骤 701、 eNodeB接收 MME发送的 Paging消息;
步骤 702、 eNodeB判断 Paging消息是否包含 MME标识;
步骤 703、 在包含 MME标识时 , eNodeB向 UE发送包含所述 MME标识 的 Paging消息。
实施中, eNodeB从 SI接口接收到 MME发送的 Paging消息时, 如果消 息中携带有 MME标识, 那么 eNodeB除了按照现有协议规则操作, 构建空中 接口 Paging消息之外, 还将在所构建的 Paging消息中包含从 Sl-AP Paging消 息中提取到的 MME标识。
实施中, 向 UE发送的 Paging消息可以是空中接口 RRC信令的 Paging 消息。
具体的, Paging消息是空中接口 RRC信令的 Paging消息时, MME标识 为 Paging消息中的条件可选项 ( C )或可选项( 0 ); 当 MME在 S1接口应用 协议 S 1 -AP Paging消息中携带有 MME标识信息时, Paging消息中包含 MME 标识。 即 MME的标识可以以条件可选项或可选项设置在 Paging消息中 , 设 置的条件是: MME在 Sl-AP Paging消息中携带有 MME标识信息。
下面以实例进行说明。
在 LTE-Uu接口方面, 可以在空中接口 RRC信令的 Paging消息中增加 MME标识信息。 修改后的 Paging消息格式如下所示:

这里, 所增加的 IE "MME-Identity" 用于记录发起 Paging过程的 MME 的标识。 "MME-Identity" IE在 Paging消息中出现的条件是: MME在 S1-AP Paging消息中携带有 MME标识信息。
图 8为 UE侧实施的 UE的寻呼处理方法流程示意图, 如图 8所示, 在进 行 UE寻呼处理时可以包括如下步骤:
步骤 801、 UE接收 eNodeB发送的 Paging消息;
步骤 802、 UE判断 Paging消息是否包含 MME标识; 步骤 803、 在包含 MME标识时, UE判断该 MME标识与 UE所注册的 MME标识是否一致;
步骤 804、 若一致, UE 响应该 Paging 消息, 若不一致, UE 不响应该 Paging消息。
实施中 , 在包含 MME标识时, UE所注册的 MME标识可以是根据当前 所使用的 GUTI中记录的 MME标识确定的。
实施中, 在收到 Paging 消息时, UE根据当前使用的 GUTI信息以及 Paging消息中携带的 MME信息,来判断发起寻呼的 MME与当前 UE所注册 的 MME是否相同。 如果相同, UE按照现有协议流程响应该寻呼消息, 否则 UE忽略该寻呼消息。 一般在实施过程中, 存在如下两种情况:
复位后的 MME发送 Paging消息时, 如果 UE还没有发起 Attach过程附 着至一个新的 MME, 那么 UE 将保存并使用原先注册时 MME 所分配的 GUTI。 这时, 将当前 GUTI中包含的 MME标识信息与 Paging消息中携带的 MME标识信息做比对, UE可以发现发起寻呼的 MME与 UE所注册的 MME 相同。 在此情况下, UE将按现有方法对指示 IMSI的 Paging消息进行响应, 即, 重新发起附着过程。
复位后的 MME发送 Paging消息时, 如果 UE已经发起 Attach过程附着 至一个新的 MME, 那么 UE将保存并使用新 MME为其分配的 GUTI。 这时, 将当前 GUTI中包含的 MME标识信息与 Paging消息中携带的 MME标识信 息做比对, UE可以发现发起寻呼的 MME不同于 UE所注册的新 MME。 在 此情况下, UE将忽略指示 IMSI的 Paging消息, 不对网络寻呼进行响应。
下面再以三者的配合实施来进行说明。
图 9为 UE的寻呼处理方法实施流程示意图,如图 9所示, EPS系统各节 点行为分别如下:
MME行为:
复位后, MME在收到 S-GW发送的包含 [IMSI, TA list]信息的 Paging Notification消息时, MME发起 Paging过程, 即 MME构建 Sl-AP Paging消 息, 其中包含自身的 MME标识, 并向 eNodeB发送。
eNodeB行为:
eNodeB从 SI接口接收到 MME发送的 Paging消息时, 如果消息中携带 有 MME标识,那么 eNodeB除了按照现有协议规则操作,构建空中接口 Paging 消息之外, 还将在所构建的 Paging消息中包含从 Sl-AP Paging消息中提取到 的 MME标识。
UE行为:
UE接收到指示 IMSI的 Paging消息时,首先查看消息中是否包含有 MME 标识。 如果 Paging消息中没有包含此标识, 那么 UE按照协议中现有的操作 流程进行处理。 否则, UE提取 MME标识信息, 并与当前所使用 GUTI中记 录的 MME标识信息做对比。 根据对比结果 UE有如下两种操作:
若对比结果相同,UE按现有协议中的流程进行处理,即响应 Paging消息。 若对比结果不同, UE则忽视接收到的 Paging消息, 对网络不 #丈响应。 基于同一发明构思, 本发明实施例中还提供了一种 MME设备、 基站设 备、 用户设备, 由于这些设备解决问题的原理与 UE 的寻呼处理方法相似, 因此这些设备的实施可以参见上述方法的实施, 重复之处不再赘述。
