Description

一种位置区更新的信息处理方法及装置
技术领域
本发明涉及通信技术领域,尤其涉及一种位置区更新的信息处理方法及装 置。 背景技术
第三代合作伙伴计划 ( 3rd Generation Partnership Project, 3GPP )在
TS23.401里面定义了演进的系统架构 ( System Architecture Evolution, SAE ) 通信网架构。在上述通信网架构中, 无线演进网络主要是由接入网与核心网两 个部分组成, 其中, 核心网主要包含移动性管理网元( Mobility Management Entity , MME )、 服务 GPRS支持节点( Serving GPRS Support Node, SGSN ) ), 与网关设备 ( Serving Gateway ( SGW )、 PDN Gateway ( PDN GW ) )逻辑功 能体,其中移动管理网元, 负责与用户设备(User Equipment, UE )之间的 NAS 信令和 NAS信令加密, 为 UE分配临时身份标识, 选择 Serving GW和 PDN GW 等核心网元,提供漫游、跟踪、安全等功能,它对应于当前 UMTS系统内部 SGSN 的控制平面部分。 Serving GW是 eNodeB之间切换的移动性锚点, 并提供合法 监听相关功能; PDN GW则负责用户地址分配, 策略控制和计费规则的执行以 及合法监听相关功能。归属地签约用户服务器(Home Subscriber Service, HSS ) 用于存储用户的签约信息。
为了方便管理 UE, 比如, 使网络侧感知到当前 UE所处的位置, 以便于 在该 UE作为被叫时寻呼该 UE, 移动性管理网元将覆盖区域通常划分多个路 由区或者跟踪区, 当 UE移动时, 进入新的路由区或者跟踪区会发起位置更新 过程:
A、 在 UMTS/GERAN系统中, UE进入新的路由区时会发起路由区更新 过程 ( Routing area update, RAU );
B、 在 LTE系统中, 为了减少位置更新过程, 可以将多个跟踪区作为一个 大的跟踪区, UE在该多个跟踪区中移动时不会发起跟踪区更新过程, 该多个 跟踪区可以称为跟踪区列表, 当 UE离开该跟踪区列表中的跟踪区时会发起跟 踪区路由更新过程。
现有技术中, UE开机后附着在 MME1上, 与相应的 SGW与 PGW也建 立了承载, 当 UE移动到另一个路由区 (UMTS的覆盖范围)或者跟踪区 (非 当前 UE的跟踪区列表中的跟踪区),发生位置更新(假设是发生路由区更新), 即移动到另一种移动性管理网元 SGSN覆盖的范围,那么则会发生如下的路由 区更新过程, 如图 1。 由图 1可知, 在该路由区更新过程中, 如果 SGW发生 了变化, 那么新的 SGW向 PGW通知其地址, 以便于 PGW将下行数据包发 送至新的 SGW, 而不是老的 SGW (步骤 6、 7实现)。
如果在上述的路由区更新过程中, 由于某些原因, 当前网络拒绝该 UE的 路由区更新过程, 比如不限于: 在步骤 10, SGSN向 HSS获取签约数据时, 由于当前位置接入受限等原因, HSS向 SGSN发送更新位置确认消息是指示 拒绝用户接入, 那么, SGSN拒绝 UE的路由区更新请求。 UE的路由区更新 请求失败(例如, 被拒绝)之后, 可能会移动到其它的路由区或者跟踪区, 重 新发起位置更新过程(包括路由区更新或者跟踪区更新)。
现在的技术中, UE回到源侧移动性管理网元(MME1 )后, MME1会向 SGW发送修改承载请求消息, 如果图 1中所示的步骤 2中启动的定时器没有 超时, 那么, MME1不会向 SGW发送删除会话请求, 那么, SGW收到该修 改承载请求消息后, 并不能感知到之前 UE发生的路由区更新失败过程, 所以 不会向 PGW发送其地址, PGW不会将 SGW的地址更新, 使得 PGW无法 将数据通道由原来路线(如图 2路线 1 )切换至新的路线(如图 2路线 2 ), 此 时, PGW仍然会按照原来的路线, 将下行数据包发送到新 SGW上, 从而导 致数据不通。
现有技术不能解决 UE移动到第二个移动性管理网元(MMEX ) 的问题, MMEX不能感知之前 UE的路由更新失败过程, 所以在跟踪区更新过程中, SGW不会向 PGW发送包含其地址的消息, 所以不能将数据通道切换回蓝色 线(如图 2路线 2 )所示的方向。 发明内容 本发明实施例提供了一种位置区更新的信息处理方法,可使服务网关地址 及时更新, 保证数据通道正常传输数据。
本发明实施例第一方面提供了一种位置区更新的信息处理方法, 其可包 括:

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作出创造 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。
参见图 3, 是本发明实施例提供的位置区更新的信息处理方法的实施例流 程示意图。 本实施例中所描述的位置区更新的信息处理方法, 包括步骤:
S101 , 当用户设备移动到新的位置区时,第一管理网元获取所述用户设备 或者第二管理网元发送的指示信息,并根据所述指示信息向服务网关发起先删 除会话再建立会话的操作请求,所述指示信息用于指示所述第一管理网元发起 先删除会话再建立会话的操作请求。 S102, 所述第一管理网元接收所述服务网关发送的创建会话请求,并向归 属地签约用户服务器 HSS发送更新位置请求。
具体实现中,本发明实施例中所描述的位置区更新可包括路由区更新或者 跟踪区更新, 下面将以路由区更新为例, 进行具体说明。
在一些可行的实施方式中, 当 UE进入到一个新的路由区时, UE可向第 一管理网元(也称目标侧移动性管理网元, MMEX )发起跟踪区更新请求, 参 见图 4, 其中, 上述第一管理网元为新的路由区的管理网元。 第一管理网元接 收到 UE发送的跟踪区更新请求之后, 则可向第二管理网元发送上下文请求, 其中, 上述第二管理网元为上述 UE移动前所处的原路由区的管理网元, 也称 源侧移动性管理网元。第二管理网元接收到第一管理网元发送的上下文请求之 后, 则可向第一管理网元发送上下文响应。 第一管理网元接收到第二管理网元 根据上述上下文请求发送的上下文响应之后,可向第二管理网元发送上下文确 认。具体实现中, 上述第二管理网元根据上述上下文请求发送的上下文响应中 携带指示信息,上述指示信息用于指示第一管理网元发起先删除会话再建立会 话的操作请求。具体的, 第二管理网元接收到第一管理网元发送的上下文请求 之后, 可判断路由区更新定时器是否正在运行, 若判断得知路由区更新定时器 正在运行, 则可向第一管理网元发送指示信息,通过该指示信息指示第一管理 网元发起先删除再建立会话的操作请求, 以告知 SGW向 PGW发送器地址, 通过 PGW更新 SGW的地址, 保证数据通道顺畅。
在一些可行的实施方式中,当第一管理网元接收到第二管理网元发送的上 下文响应之后, 若判断得知上述上下文响应中包括上述指示信息, 则可向服务 网关(SGW )发起先删除会话再建立会话的操作请求, SGW接收到第一管理 网元发送的先删除会话再建立会话的操作请求之后,可向第一管理网元发送创 建会话请求。 第一管理网元接收到 SGW发送的创建会话请求之后, 则可向 HSS发送更新位置请求。 HSS接收到第一管理网元发送的更新位置请求之后, 可向第二管理网元发送取消位置消息, 第二管理网元接收到 HSS发送的取消 位置信息后, 向 HSS发送取消位置确认消息; HSS接收到第二管理网元发送 的取消位置确认消息后, 则可向第一管理网元发送更新位置响应。 进一步的, 第一管理网元接收到 HSS发送的更新位置响应之后, 可向 UE发送跟踪区更 新接受消息。 第一管理网元向 UE发送跟踪区更新接受消息, 并接收 UE发送 的跟踪区请求确认, 完成位置区更新的信息处理。
在一些可行的实施方式中,上述用于指示第一管理网元发起先删除会话再 建立会话的操作请求的指示信息,除了上述实施例中所描述的可通过第二管理 网元向第一管理网元发送上下文响应时将上述指示信息发送给第一管理网元
(如图 4中的步骤 3 )之外, 当 UE在完成跟踪区更新失败(例如, 被拒绝 ) 时, UE可釆用第二管理网元分配的用户设备标识发起跟踪区更新请求, 即, UE可向第一管理网元发送跟踪区更新请求, 通过向第一管理网元发送的跟踪 区更新请求将上述指示信息发送给第一管理网元(如图 5中的步骤 1 )。 第一 管理网元接收到 UE发送的跟踪区更新请求时则可从上述跟踪区更新请求中获 取得到上述指示信息。第一管理网元在接收到第二管理网元发送的上下文确认 之后,若判断得知上述接收到的 UE发送的跟踪区更新请求中携带上述指示信 息 (即, 接收到图 5中的步骤 1的指示信息), 则可向 SGW发起先删除会话 再建立会话的操作请求,进而可接收 SGW发送的创建会话请求并向 HSS发送 更新位置请求等消息, 以完成位置区更新的信息处理。
在本发明实施例中, 在位置区更新过程中, 如果源侧移动性管理网元(即 第二管理网元)上运行了定时器, 则可向目标侧移动性管理网元(即第一管理 网元)发送指示信息, 指示其发起先删除会话再建立会话的操作; 在位置区更 新过程中, 如果之前 UE发起了位置区更新过程并且失败, 则重新再发起的位 置区更新时 UE可向第一管理网元发送位置区更新请求, 并可在向第一管理网 元发送的位置区更新请求中添加指示信息,将指示信息发送给目标侧移动性管 理网元(即第一管理网元), 以便于当前的移动性管理网元(即第一管理网元) 发起先删除会话再建立会话的操作。本发明实施例可通过指示信息指示第一管 理网元发起先删除会话再建立会话的操作,使服务网关地址及时更新,保证数 据通道正常传输数据。
参见图 6, 是本发明实施例提供的位置区更新的信息处理装置的实施例结 构示意图。 本实施例中所描述的位置区更新的信息处理装置, 包括:

在一些可行的实施方式中, 上述第一请求模块 10获取所述用户设备或者 第二管理网元发送的指示信息时, 具体用于:
向第二管理网元发送上下文请求,并接收所述第二管理网元发送的上下文 响应, 从所述上下文响应中获取所述指示信息;
其中,所述指示信息为所述第二管理网元接收到所述上下文请求并判断得 知位置区更新定时器正在运行时, 向第一管理网元发送的指示信息。
具体实现中,本发明实施例中所描述的位置区更新的信息处理装置具体可 为本发明实施例提供的位置区更新的信息处理方法实施例中所描述的第一管 理网元, 本发明实施例中所描述的第一管理网元为新的位置区的管理网元(也 称目标侧移动性管理网元, MMEX ); 本发明实施例中所描述的第二管理网元 为用户设备移动前所处的原位置区的管理网元,也称源侧移动性管理网元。本 发明实施例中所描述的位置区更新可包括路由区更新或者跟踪区更新,下面将 以路由区更新为例, 进行具体说明。
在一些可行的实施方式中, 当 UE进入到一个新的路由区时, UE可向第 一管理网元(MMEX )发起跟踪区更新请求。 第一管理网元可通过第一请求模 块 10接收 UE发送的跟踪区更新请求, 第一请求模块 10接收到 UE发送的跟 踪区更新请求之后, 则可向第二管理网元发送上下文请求。 第二管理网元接收 到第一管理网元发送的上下文请求之后, 则可向第一管理网元发送上下文响 应。 第一管理网元可通过第一请求模块 10接收第二管理网元发送的上下文响 应, 第一请求模块 10接收到第二管理网元根据上述上下文请求发送的上下文 响应之后, 则可向第二管理网元发送上下文确认。 具体实现中, 上述第二管理 网元根据上述上下文请求发送的上下文响应中携带指示信息, 即, 第一管理网 元的第一请求模块 10可从第二管理网元发送的上下文响应中获取指示信息, 上述指示信息用于指示第一管理网元发起先删除会话再建立会话的操作请求。 具体的, 第二管理网元接收到第一管理网元的第一请求模块 10发送的上下文 请求之后, 可判断路由区更新定时器是否正在运行, 若判断得知路由区更新定 时器正在运行, 则可向第一管理网元发送指示信息,通过该指示信息指示第一 管理网元发起先删除再建立会话的操作请求, 以告知 SGW向 PGW发送器地 址, 通过 PGW更新 SGW的地址, 保证数据通道顺畅。
在一些可行的实施方式中, 当第一管理网元的第一请求模块 10接收到第 二管理网元发送的上下文响应之后,若从上述上下文响应中获取得到上述指示 信息, 第一请求模块 10则可向服务网关(SGW )发起先删除会话再建立会话 的操作请求, SGW接收到第一管理网元发送的先删除会话再建立会话的操作 请求之后, 可向第一管理网元发送创建会话请求。 第一管理网元的第二请求模 块 20接收到 SGW发送的创建会话请求之后,则可向 HSS发送更新位置请求。 HSS接收到第一管理网元发送的更新位置请求之后,可向第二管理网元发送取 消位置消息, 第二管理网元接收到 HSS发送的取消位置信息之后, 可向 HSS 发送取消位置确认消息, HSS接收到第二管理网元发送的取消位置确认消息 后, 再向第一管理网元发送更新位置响应。 第一管理网元接收到 HSS发送的 更新位置响应后, 可向 UE发送跟踪区更新接受消息。 第一管理网元向 UE发 送跟踪区更新接受消息, 并接收 UE发送的跟踪区请求确认, 完成位置区更新 的信息处理。
在一些可行的实施方式中, 上述第一请求模块 10获取所述用户设备或者 第二管理网元发送的指示信息时, 具体用于:
接收所述用户设备发送的位置区更新请求,从所述位置区更新请求中获取 所述指示信息;
其中, 所述指示信息为所述用户设备完成位置区更新失败时, 釆用用户设 备标识发起新的位置区更新请求时携带的指示信息,所述用户设备标识为所述 第二管理网元分配的。
在一些可行的实施方式中,上述用于指示第一管理网元发起先删除会话再 建立会话的操作请求的指示信息,除了上述实施例中所描述的可通过第二管理 网元向第一管理网元发送上下文响应时将上述指示信息发送给第一管理网元 (如图 4中的步骤 3 )之外, 当 UE在完成跟踪区更新失败(例如, 被拒绝 ) 时, UE可釆用第二管理网元分配的用户设备标识发起跟踪区更新请求, 即, UE可向第一管理网元发送跟踪区更新请求, 通过向第一管理网元发送的跟踪 区更新请求将上述指示信息发送给第一管理网元(如图 5中的步骤 1 )。 第一 管理网元的第一请求模块 10接收到 UE发送的跟踪区更新请求时则可从上述 跟踪区更新请求中获取得到上述指示信息。第一管理网元在接收到第二管理网 元发送的上下文确认之后,若从上述接收到的 UE发送的跟踪区更新请求中获 取得到上述指示信息 (即, 接收到图 5中的步骤 1的指示信息), 可通过第一 请求模块 10向 SGW发起先删除会话再建立会话的操作请求, 进而可通过第 二请求模块 20接收 SGW发送的创建会话请求并向 HSS发送更新位置请求等 消息, 以完成位置区更新的信息处理。
在本发明实施例中, 在位置区更新过程中, 如果源侧移动性管理网元(即 第二管理网元)上运行了定时器, 则可向目标侧移动性管理网元(即第一管理 网元)发送指示信息, 指示第一管理网元发起先删除会话再建立会话的操作; 在位置区更新过程中, 如果之前 UE发起了位置区更新过程并且失败, 重新再 发起的位置区更新时 UE可向第一管理网元发送位置区更新请求, 并可在向第 一管理网元发送的位置区更新请求中添加指示信息,将指示信息发送给目标侧 移动性管理网元(即第一管理网元)。 第一管理网元接收到指示信息之后, 则 可先向 SGW发起先删除会话再建立会话的操作, 在向 SGW发送创建会话请 求, 并向 HSS发送更新位置请求。 本发明实施例中所描述的位置区更新的信 息处理装置可根据指示信息发起先删除会话再建立会话的操作,使服务网关地 址及时更新, 保证数据通道正常传输数据。
