Description

实现家庭基站回程网络服务质量控制的方法、 设备及系统 技术领域
本发明实施例涉及通信技术领域, 并且更具体地, 涉及一种实现家庭基 站回程网络服务质量控制的方法、 设备及系统。 背景技术
第三代合作项目 ( 3rd Generation Partnership Project, 筒称 3GPP ) 中定 义的演进分组核心网 ( Evolved Packet Core , 筒称 EPC ) 架构是移动网络的 网络架构, 以长期演进( Long Term Evolution , 筒称 LTE ) 系统为例, EPC 架构中的主要网元的功能描述如下:
分组数据网 (Packet Date Network , 筒称 PDN ) 网关 PDN Gateway ( PGW ): 该网元为 EPC网络与提供服务的 PDN网络(该网络可能是运营 商内部或外部的分组网络)的接口网关,负责对用户数据流进行转发和过滤, 以及用户互联网协议(Internet Protocol , 筒称 IP )地址的分配, 服务质量 ( Quality of Service , 筒称 QoS )策略的执行、 计费等。
服务网关 (Serving Gateway, 筒称 SGW ): 主要负责在用户设备 (User Equipment, 筒称 UE)和 PGW之间中继用户业务流, 以及基站间切换时, 作 为锚定点。
移动性管理实体 ( Mobility Management Entity, 筒称 MME ): 主要负责 用户的移动性管理, 用户的附着信令处理等。
家乡签约服务器 ( Home Subscriber Server, 筒称 HSS ): 主要存储用户 的签约信息, 完成对用户的鉴权。
策略控制和计费规则功能实体 ( Policy Control and Charging Rules Function, 筒称 PCRF ): 该功能实体根据用户接入网络的限制,运营商策略, 用户签约数据以及用户当前正在进行的业务信息等决定对应的策略, 并将该 策略提供给传输网关执行, 从而实现策略计费控制。
演进的通用陆地无线接入网 ( Evolved Universal Terrestrial Radio Access Network, 筒称 E-UTRAN ): 该网元为基站系统, 提供与用户间的空口资源 管理, 数据流转发等。
当 UE开机检测到移动网络时, 会发送附着信令至 MME (该信令通过 E-UTRAN转发)。 MME根据 HSS内存储的用户签约数据对 UE进行鉴权, 鉴权通过后, MME会发起 IP连通接入网络( IP Connectivity Access Network, 筒称 IP-CAN )会话的建立流程。 MME首先发送会话建立请求至 SGW, 然 后由 SGW到 PGW, 从而为用户建立一条数据传输隧道(如, GTP隧道)。 该通用分组无线业务( General Packet Radio Service, 筒称 GPRS ) 隧道协议 ( GPRS Tunneling Protocol,筒称 GTP )隧道从 E-UTRAN经过 SGW至 PGW, 最后由 PGW连接到 PDN网络, 至此, 建立起 UE到 PDN网络之间的关联。 在 IP-CAN会话建立过程中, PGW与 PCRF间会为用户建立 Gx会话, 该会 话属于 IP-CAN会话的一部分, 用于 PCRF传递针对用户的策略控制信息给 PGW, PGW通过 GTP信令将相应的 QoS信息传递给数据路径上的 SGW、 E-UTRAN。
宽带论坛 ( Broadband forum, 筒称 BBF ) 架构是一种固定网络的架构, 主要网元 ¾口下:
宽带远端接入服务器 /宽带网络网关 (Broadband Remote Access Server /Broadband Network Gateway, 筒称 BRAS/BNG): 该网元为 BBF网络的汇聚 节点, 将 BBF网络的点对点协议( Point-to-Point Protocol, 筒称 PPP )会话、 IP会话、 异步传输模式(Asynchronous Transfer Mode, 筒称 ATM )会话汇 聚后通过 A10接口与外部网络连接。 即, 该网元是 BBF网络与外部网络的 接口网关, 负责对用户数据流进行汇聚、转发和过滤,还具有一些其他功能, 例如用户 IP地址的分配, QoS策略的执行, 计费等, 类似于 PGW。
接入节点 (Access Node, 筒称 AN): 该网元为二层设备, 进行二层数据 的汇聚与转发。 主要功能为终结数字用户线( Digital Subscriber Line , 筒称 DSL )信令并在接入网和区域网间实现汇聚功能, 一般位于数字用户线路接 入复用器( Digital Subscriber Line Access Multiplexer,筒称 DSLAM )设备中。
用户驻地设备 (Customer Premises Equipment, 筒称 CPE): —般为家庭 网关,用于家庭网络与接入网络间数据的转发路由,虚拟局域网( Virtual Local Area Network,筒称 VLAN )标签的封装等,一般为具有路由器功能的 DSLAM 调制解调器。
策略决策点 (Policy Decision Point, 筒称 PDP): 该网元主要功能为策略 制定, 即为用户、 IP流或者汇聚流制定 QoS策略, 并将 QoS策略下发至策 略执行点 (Policy Enforcement Point, 筒称 PEP)执行, 类似于 3GPP网络中 的 PCRF 功能实体; 在互通场景下该网元也被称作宽带策略控制功能 ( Broadband Policy Control Function , 筒称 BPCF )。
BBF网络中, 用户终端附着至 CPE后, BRAS/BNG结合认证, 授权和 计帳 ( Authentication, Authorization and Accounting, 筒称 AAA )月良务器对用 户进行鉴权并为用户分配 IP地址, 用户终端通过该 IP地址对外部网络进行 访问。
BBF与 3GPP网络互通有两种场景, 一种是用户设备通过家庭基站接入
EPC网络, BBF网络为家庭基站提供回程网络服务;一种是用户设备直接附 着至 BBF网络, 通过隧道连接回 EPC网络。
家庭基站是用于增强移动网络的无线覆盖范围,提高无线带宽的一种解 决方案。主要方法是在用户的家中或者公共场所部署一个家庭基站 (HeNB或 者 HNB) , 用户通过家庭基站附着至 EPC。
家庭基站接入与宏基站接入的区别在于回程网络不同。 回程网络是指基 站与核心网设备 (例如 SGW、 MME等)之间的传输网络。
宏基站的回程网络一般是移动运营商的专有网络或者是租用固定运营 商的专线, 该回程网络由于是专用网络, 一般情况下不会拥塞, 业务的带宽 时延等 QoS参数都能够得到保证,因此不需要对回程网络内部的节点进行额 外的 QoS控制。
家庭基站的回程网络采用 BBF网络。 由于 BBF网络并非专用网络, 可 能会产生拥塞, 因此必须对回程网络进行 QoS控制, 以保证业务的 QoS需 求。
家庭基站架构的主要网元如下:
3GPP Femto: 家庭基站, 例如 2G/3G系统中的 Home NodeB ( HNB ), LTE系统中的 Home eNodeB ( HeNB )„
安全网关 (Security Gateway, 筒称 SeGW) : 安全网关位于移动核心网络 的边缘, 用于确保合法的家庭基站接入移动核心网, 对家庭基站进行鉴权, 并与家庭基站间建立安全隧道进行数据传输。
家庭基站网关 ( H(e)NB Gateway, 筒称 HeNB GW或者 HNB GW ): 用 于汇聚多个家庭基站至一个接口上, 一般与安全网关合设。
家庭基站开机后, 附着至 BBF网络, BBF网络对家庭基站进行鉴权、
IP地址分配。 家庭基站获得 BBF网络分配的本地 IP地址后, 用本地 IP地 址与 SeGW建立安全隧道 (即, IPSec隧道), 后续家庭基站发往 MME或者 SGW的信令或者数据报文通过该安全隧道传输。 UE附着至家庭基站时, 与 附着至 EPC的流程相同, 由 PGW为 UE分配 IP地址。 UE发送的信令与数 据报文由家庭基站封装至 IPsec隧道内传输至 EPC网络。
现有技术中, UE通过家庭基站( HeNB )连接至 EPC网络的过程主要 包括以下步骤:
步骤一, HeNB启动后, 由 BBF网络为其分配一个本地(Local ) IP地 址, HeNB使用本地 IP地址连接至 EPC网络的 SeGW, SeGW对 HeNB鉴 权后, 与 HeNB间建立一条 IPsec隧道;
步骤二, UE通过 HeNB附着时, HeNB在 UE的附着信令中插入 HeNB 与 SeGW间的 IPsec隧道信息(包括 HeNB的本地 IP地址等信息), MME获 取该 IPsec隧道信息后,在为 UE创建 IP-CAN会话时在消息中携带 IPsec隧 道信息, 通过 GTP信令传递给 PGW, 进一步传递给 PCRF;
步骤三,为了实现 BBF网络段 (即, HeNB回程网络)的 QoS控制, PCRF 进行策略决策后下发 QoS规则至 BPCF, 由 BPCF将该 QoS规则传递给 BRAS , 其中, 该 QoS规则中携带 HeNB与 SeGW间的 IPsec隧道信息, 以 便于 BRAS根据 IPsec隧道信息识别出 HeNB与 SeGW间的数据流,从而进 行 QoS控制。
但是, 在实际应用中, BBF网络会更改分配给 HeNB的本地 IP地址。 当 HeNB的本地 IP地址更新后, HeNB与 SeGW间的 IPsec隧道也会随之更 新。由于 BRAS是根据 IPsec隧道信息来识别数据流进行 QoS控制的,因此, IPsec隧道信息的更新将导致原有的 QoS规则失效。 而在现有技术中, HeNB 不会将新的 IPsec隧道信息上报给 MME,并进一步通知 PCRF,从而, PCRF 无法携带更新后的 IPsec隧道信息给 BBF网络,使得 HeNB的回程网络无法 获得 QoS保证, 进而 BRAS不对新隧道进行 QoS控制。 这会导致在 BBF网 络带宽资源紧张的情况下, 出现 UE数据包丟失甚至 HeNB回程网络连接中 断的情况, 导致 UE的业务体验变差。 发明内容
本发明实施例提供一种实现家庭基站回程网络 QoS控制的方法、设备和 系统, 能够解决家庭基站的本地 IP地址更新后, 原有的 QoS规则失效, 且 新隧道无法获得 QoS保证的问题, 提高了用户体验。

另一方面,提供了一种实现家庭基站回程网络 QoS控制的系统, 包括上 述的家庭基站和移动性管理网元。

图 1是根据本发明一个实施例的实现家庭基站回程网络 QoS控制方法的 流程图。 具体包括以下步骤:
步骤 101 , 当家庭基站更新与安全网关之间的 IPsec隧道后, 移动性管 理网元接收家庭基站上报的家庭基站配置信息更新请求, 所述家庭基站配置 信息更新请求中携带有更新后的 IPsec隧道信息。
家庭基站在本地 IP地址续租(renew ) 并更新与安全网关之间的 IPsec 隧道后, 判断隧道信息发生了变化, 于是通过家庭基站配置信息更新请求将 新的 IPsec隧道信息上 4艮给移动性管理网元。 其中, 所述家庭基站本地 IP地 址续租, 可由 BBF网络重新分配家庭基站的本地 IP地址触发, 也可以由家 庭基站在使用 IPv6地址时, 更改 Interface-ID触发; 所述 IPsec隧道信息包 含但不限于: 家庭基站的本地 IP地址与端口号, 安全网关的本地 IP地址与 端口号。

具体地,移动性管理网元收到家庭基站发送的所述家庭基站配置信息更 新请求后, 根据其中携带的更新后的 IPsec隧道信息识别受影响的家庭基站 下的 UE或和所述 UE相关的 IP-CAN会话或 PDP上下文。 针对上述识别出 来的 UE、 IP-CAN会话和 PDP上下文, 移动性管理网元可以通过以下方式 之一, 将更新后的 IPsec隧道信息通知给 PCRF:
方式一,移动性管理网元识别受影响的家庭基站下的 UE相关的 IP-CAN 会话, 针对所述 IP-CAN会话向分组数据网网关发送承载修改请求, 以便所 述分组数据网网关向所述 PCRF发送会话修改请求, 其中所述承载修改请求 和所述会话修改请求携带所述更新后的 IPsec隧道信息;

下面结合具体例子, 详细描述本发明的实施例。 图 2是根据本发明一个 实施例的实现家庭基站回程网络 QoS控制方法的示意流程图。 图 2中,具体 描述了在 EPC网络架构下, HeNB的本地 IP地址发生变化后, 向网关更新 隧道信息, 并通过网络侧修改 IP-CAN会话来使新隧道获得 QoS保证。 需要 说明的是, 本实施例同样适用于 GPRS S4/S5/S8网络架构下, HNB的本地 IP地址发生变化的场景,此时,由 S4-SGSN作为移动性管理网元,取代 MME 的作用。 如图 2所示, 具体包括以下步骤:
步骤 201 , HeNB发起本地 IP地址续租流程。
该流程可由 BBF网络重新分配 HeNB 的本地 IP地址触发, 也可以由 HeNB在使用 IPv6地址时, 更改 Interface-ID触发。
