Description

网元状态信息处理方法、 装置、 MME及 HSS 技术领域 本发明涉及通信领域, 具体而言, 涉及一种网元状态信息处理方法、 装置、 移动 管理实体 (Molality Management Entity, 简称为 MME) 及归属用户服务器 (Home Subscriber Server, 简称为 HSS)。 背景技术 第三代合作伙伴计划(3rd Generation Partnership Project, 简称为 3GPP)对下一代 移动无线网络的项目叫系统架构演进 (System Architecture Evolution, 简称为 SAE)。 图 1是相关技术中 SAE的架构示意图, 如图 1所示, 该 SAE包括: 演进的无线接入网 (Radio Access Network, 简称为 RAN), 可以提供更高的上下 行速率, 更低的传输延迟和更加可靠的无线传输。 E-RAN 中包含的网元是演进节点 ( Evolved NodeB, 简称为 eNodeB ), 为终端的接入提供无线资源。 归属用户服务器(Home Subscriber Server,简称为 HSS),永久存储用户签约数据。 分组数据网 (Packet Data Network, 简称为 PDN), 为用户提供业务的网络。 演进的分组网 (E-Packet Core), 提高了更低的延迟, 并允许更多的无线接入系统 接入。 包含了如下网元: 移动管理实体 (Mobility Management Entity, 简称为 MME): 控制面功能实体, 临时存储用户数据的服务器, 负责管理和存储 UE 上下文 (比如, UE/用户 标识, 移 动性管理状态, 用户安全参数等), 为用户分配临时标识, 当 UE驻扎在该跟踪区域或 者该网络是负责对该用户进行鉴权; 处理 MME和 UE之间的所有非接入层消息; 触 发在 SAE的寻呼。 服务网关 (Serving Gateway, 简称为 S-GW): 该网关是一个用户面实体, 负责用 户面数据路由处理, 终结处于空闲状态的 UE的下行数据。 管理和存储 UE的 SAE承 载(bearer)上下文, 比如, IP承载业务参数和网络内部路由信息等。 是 3GPP系统内 部用户面的锚点, 一个用户在一个时刻只能有一个 Serving GW; 分组数据网网关 (PDN GW): 负责 UE接入 PDN的网关, 分配用户 IP地址, 同 时是 3GPP和非 3GPP接入系统的移动性锚点。 用户在同一时刻能够接入多个 PDN GW。 策略和合计费规则功能实体 (Policy and Charging Rule Functionality, 简称为 PCRF): 该功能实体主要根据业务信息和用户签约信息以及运营商的配置信息产生控 制用户数据传递的服务质量 (Quality of Service, 简称为 Qos) 规则以及计费规则。 该 功能实体也可以控制接入网中承载的建立和释放。 在 SAE 网络中的每个网元都存在可靠性问题, 每个网元都有可能出现宕机的情 况。 同时网络中的其它网元对该网元状态可能是敏感的, 即该网元状态是正常还是宕 机状态, 其它网元的处理会有不同。 这些不同包括: 将与已宕机网元相关的资源 /用户 置为无效或回收; 在后续业务接续时, 不选择已宕机的网元; 在宕机网元恢复正常后, 重新选择该网元等。 但是目前网络中不是每个网元都知道其它网元的状态。 根据目前的机制, 相邻节 点间可以获取到互相的状态的, 比如, HSS与 MME间、 MME与 SGW间、 SGW与 PGW间都是可以互相检测出来。 部分非相邻节点间也可以知道对方状态, 如 MME可 以获取 PGW的状态。 但是在相关技术中, HSS是无法获取 SGW、 PGW的状态的。 因此, 在相关技术中存在 HSS无法获取 SGW、 PGW网元状态的问题。 发明内容 本发明提供了一种网元状态信息处理方法、 装置、 MME及 HHS, 以至少解决相 关技术中存在的 HSS无法获取 SGW、 PGW网元状态的问题。 根据本发明的一个方面, 提供了一种网元状态信息处理方法, 包括: 将服务网关 S-GW的 S-GW网元状态信息和 /或分组数据网络网关 PDN GW的 PDN GW网元状态 信息发送给归属用户服务器 HSS。 优选地,所述 S-GW网元状态信息包括以下至少之一:所述 S-GW宕机、所述 S-GW 正常;
