图 1为本发明实施例一所提供的一种网络设备的结构示意图。 本实施 例的网络设备适用于根据 UE地理区域实现网络管理的情况。 该网络设备 可以以硬件和软件的方式来实现, 可以集成在该网络设备的存储器中, 例如 集成在处理器芯片中, 供处理器调用执行。 本实施例的网络设备具体包括: 接收模块 11、 解析模块 12、 确定模块 13和获取模块 14。
其中, 接收模块 11, 用于接收 UE发送的用户激活请求, 该用户激活请 求包括用户位置信息 (User Location Information, 简称为: ULI) 。 当前的网络运营商, 例如中国移动、 联通和电信通常要求网关可以基于
UE的位置信息对其进行管理控制, 因此, 要求 UE的 IP地址与其所在区域 实施对应, 网络设备可以根据 UE的 IP地址执行相应的管理策略; 在 EPS网 络中, MME 只负责移动性管理、 信令处理等功能, S-GW 与演进型基站 (Evolved Node B, 简称为 eNB ) 连接, 主要负责用户设备的数据传输、 转 发以及路由切换等功能, P-GW负责 UE的 IP地址分配、服务质量(Quality of Service, 简称为: QoS ) 保证、 计费等功能, EPS 网络中的数据流量可以直 接从 eNB到 S-GW或 P-GW, 不经过 MME, 但是 eNB属于 EPS中的网元, 并不属于演进型分组核心网(Evolved Packet Core, 简称为: EPC)中的网元, 因此, 虽然 eNB可以做自身的数据流量统计, 但是, 一方面 eNB不属于 EPC 中的网元,不能对 EPC中各网元的数据流量进行统计管理,另一方面,当 EPS 网络中 eNB的数目很多, 不利于统计数据的汇总。 因此, 当前 EPS网络中, EPC缺少可以基于地理区域范围实现对 UE进行统一管理的网元。
本发明实施例提供的网络设备可以基于 UE的位置信息执行 APN的分配 任务, 并基于已分配的 APN进行网络管理功能, 具有全面的使用性能, 并广 泛适用于 2G/3G网络、 EPS网络以及 CDMA网络等; 本实施例以 EPS网络 为例予以说明, 网络设备可以为 MME或则 P-GW, 具体地, 演进型通用陆地 无线接入网 (Evolved Universal Terrestrial Radio Access Network, 简称为: E-UTRAN) 通常为由多个 eNB组成的网络, 其中, eNB通过 GPRS隧道协 议(GPRS Tunnel Protocol, 简称为: GTP)用户面( GTP User Plane, 简称为: GTP-U) 接口与 S-GW连接, 用于传输用户数据, 通过控制面接口与 MME 连接, 当 UE请求接入 EPS网络时发起附着流程, 并携带用户激活请求, 网 络设备可以在 MME接收到由 eNB转发的用户激活请求时由 MME执行 APN 的分配, 另夕卜, 也可以在 MME将用户激活请求通过 S-GW转发给 P-GW后, 由 P-GW执行 APN的分配; 需要说明的是, MME和 P-GW执行 APN的分 配所采用的方式是相同的, 在 2G/3G网络中, 可以通过 SGSN或者 GGSN执 行 APN的分配。 本实施例具体以 P-GW执行 APN的分配为例予以说明, 该 P-GW接收的用户激活请求中包括 ULI, 该 ULI用于指示 UE的当前地理区 域。
需要说明的是, UE通过附着流程接入 EPS网络并创建 PDN连接的过程 为现有技术的方法, 在此不具体描述; UE在接入网络时, MME可以根据该 UE的位置区域选择的适合 UE的 P-GW; 本实施例提供的网络设备均为 EPC 中的网元, 并且在 EPS网络中可以通过该网络设备实现基于地理区域范围对 UE进行管理,并且也可以根据该 UE的地理区域对 EPS中可以实现的功能进 行网络管理。
解析模块 12, 用于对该接收模块 11接收的 ULI进行解析, 获取该 UE 所在位置的区域码。
在本实施例中, P-GW对用户激活请求中的 ULI进行解析, 该 ULI所指 示 UE所在的地理区域, E-UTRAN中同样设置有多个 P-GW, 在同一个 eNB 覆盖范围内的 UE通常通过同一个 P-GW与外部网络进行数据传输,即 P-GW 根据对所接收的 ULI的解析结合, 获知 UE指示所在位置的区域码, 具体地, 指示 UE所在位置的区域码可以包括 UE的位置区编码(Location Area Code, 简称为: LAC) 、 路由区编码 (Routing Area Code, 简称为: RAC) 或者跟 踪区编码 (Tracking Area Code, 简称为: TAC) 。
需要说明的是, 当 UE 由于地理区域变化而发生数据路由时, 需要重新 建立 PDN连接, 并且重新发送的用户激活请求中包括的 UE位置变化后的 ULI, 对该 ULI的解析结果和重新获取的区域码也发生变化。
确定模块 13, 用于确定解析模块 12获取的区域码所属的区域码集合; 其中,该区域码集合中的区域码所指示的用户位置在同一个地理区域范围内。
在本实施例中, P-GW通过 eNB与 UE进行交互, 通常可以将 UE的地 理区域信息作为网络管理的基本信息, 对 eNB覆盖区域中的多个 UE进行网 络管理, 即可以根据 eNB覆盖区域中 UE的区域码对其进行管理, 因此, 该 P-GW中配置有区域码集合, 以及该区域码集合和实际 APN的映射关系, 该 集合中包括可以通过该 P-GW与外部网络进行数据传输的所有 UE的区域码, 并且 P-GW通过管理该集合中的区域码为网络管理作出指导, 通常地, 将已 知的 UE的区域码在该集合中进行査找,确定该 UE的区域码所属的区域码集 合; 需要说明的是, 同一区域码集合中的区域码所指示的用户位置在同一个 地理区域范围内, 即相同地理区域范围内的 UE的区域码被映射到同一个区 域码集合中。
需要说明的是, 当 UE 由于地理区域变化而重新发送的户激活请求时, 由于该请求中包括的 UE位置变化后的 ULI,即 UE的区域码发生变化,因此, P-GW需要重新确定该 UE的区域码所属的区域码集合。
获取模块 14, 用于根据确定模块 13确定区域码集合, 与实际 APN的映 射关系为该 UE获取该实际 APN。
在本实施例中, P-GW 中不仅配置有区域码集合, 还配置有该区域码集 合与实际 APN的映射关系, P-GW可以根据该映射关系对请求接入的 UE在 选取实际接入 APN时进行管理规划, 例如可以预先提供已规划的接入规则; 该映射关系具体为设计人员预置的一种映射规则, 可以结合 UE的区域码和 该区域码在 P-GW中所属的区域码集合,将该 UE映射到实际接入的 APN中, UE与实际接入的 APN的映射, 实际上是该 UE所在地理区域与其实际接入 的 APN的映射, 也就是该 UE的区域码在 P-GW中所属的区域码集合与实际 接入的 APN的映射, gp, 本实施例提供的 P-GW根据 UE实际接入的 APN 所进行的网络管理, 实际上就是基于地理区域范围对 UE进行的网络管理。
需要说明的是, 一方面, 3GPP 协议中可以通过策略与计费规则功能 (Policy and Charging Rules Function, 简称为: PCRF) 网元进行策略控制, 但是该 PCRF网络的部署需要增加硬件设施, 挺高网络系统的成本, 不是所 有现网中都会部署该网元。 另一方面, 在现网运营中, 运营商提出基于用户 位置区域进行各种网络管理策略的需求, 例如带宽管理, 接入 UE的数量控 制、 计费管理和数据流量统计等; 但在 EPS网络中, S-GW和 P-GW上并不 负责对位置区域进行管理; 如果为满足需求在 SGW/PGW上建立起一套基于 位置区域的管理机制, 则需要耗费巨大的工作量和硬件成本; 举例来说, 基 于用户的位置区域分配 IP地址, 则需要建立起一套位置区域与地址池的绑定 管理机制; 基于用户位置区域的性能统计, 则需要新建一套基于位置区的测 量对象, 以及新增上百乃至上千项以位置区域测量对象的性能统计项; 基于 位置区进行接入用户数或者带宽的控制, 则需要维护在每个位置区域进行用 户数量或者使用带宽的统计。
本实施例提供的网络设备, UE实际接入的 APN中标识了通过该 P-GW 所连接的外部网络, 例如互联网服务提供商 (Internet Service Provider, 简称 为: ISP)网络、企业网等;或者该 APN所关联的某种类型的业务,例如 Internet 接入、 无线应用协议(Wireless Application Protocol, 简称为: WAP)业务等; 同时实际 APN也是 P-GW上进行用户划分的一个单位,即在 P-GW中可以基 于 UE实际接入的 APN进行用户性能策略的配置,比如计费测量、 QoS保证、 安全和业务控制, 不同的 APN可以有不同的策略, 从而实现灵活计费和业务 控制。
本实施例所提供的网络设备, 接收模块接收请求接入网络的 UE发送的 用户激活请求, 该用户激活请求中包括 UE的 ULI, 通过解析模块对 ULI的 解析获取所述 UE所在位置的区域码, 并通过确定模块确定出该区域码所属 的区域码集合, 进而获取模块根据该 UE的区域码所属的区域码集合, 与实 际 APN的映射关系为该 UE获取实际 APN; 本实施例实现了将同一物理区 域范围内的 UE接入到同一个实际 APN, 对该实际 APN下的 UE进行管 理即是对处于同一物理区域范围内的 UE进行管理, 因此能够实现基于物 理区域范围内对 UE进行统一管理。
实施例二
图 2为本发明实施例二所提供的一种网络设备的结构示意图。 在上述 图 1提供的网络设备基础上,本实施例中,网络设备中配置的区域码集合, 以及该区域码集合和实际 APN 的映射关系可以具体配置在存储模块 15 中; 可选地, 接收模块 11接收的用户激活请求中还包括 UE请求的 APN; 相应地, 确定模块 13, 还用于在解析模块 12对 ULI进行解析前, 确定该 UE 请求的 APN在实际 APN中具有签约信息。
本实施例同样以在 EPS网络中通过 P-GW进行网络管理为例予以说明,
P-GW接收到 UE发送的激活请求时, 根据 UE所请求的 APN在其实际 APN 中査询该 UE是否具有签约信息, UE请求的 APN为 UE在运营商的规划中 已签约的网络, 例如可以包括移动、 联通或电信等, 由于请求接入 P-GW的 UE的签约地理区域可能与该 P-GW不在同一地理区域范围中, 因此, P-GW 接收到用户激活请求时, 可以根据该 UE所请求的 APN査询其配置的映射关 系中所具备的实际 APN是否与该 UE请求的 APN具有签约信息, 以确认是 否对该 UE分配实际 APN。
本实施例的区域码同样包括 LAC、 RAC或者 TAC, 以区域码为 LAC为 例进行说明, 区域码集合即为 LAC GROUP, 通常地, 一个 LAC号段包括多 个 LAC ID (Identity, 标识号码), 一个 LAC GROUP由多个 LAC号段组成, 即存储模块 15 中配置有该区域码集合和区域码号段。 相应地, 在解析模块 12对接收模块 11接收的 ULI进行解析, 获取到该 UE所在位置的区域码后, 确定模块 13具体将已获取的 UE的区域码在该存储模块 15中配置的区域码 号段和区域码集合中进行査找, 获取该 UE的区域码所属的区域码集合。
在具体实现中, P-GW接收到用户激活请求时, 从该请求的 ULI中可以 解析出 LAC、 RAC或者 TAC的值; 需要说明的是, 还可以解析用户激活请 求中的路由区标识 (Routing Area Identity, 简称为: RAI) , 具体地, 通过 gtpvO/gtpvl 协议发送的用户激活请求为创建分组数据协议 (Packet Data Protocol, 简称为: PDP)上下文请求( Create PDP Context Request ), 该 gtpvO 协议的请求中包括 RAI信元,该 gtpvl协议的请求中包括 ULI和 /或 RAI信元, 通过 gtpv2 协议发送的用户激活请求为创建会话请求 (Create Session Request) , 该 gtpv2协议的请求中包括 ULI信元。 在获取 LAC、 RAC或者 TAC的值后, 可以在 P-GW中配置的区域码号段和区域码集合中进行査找, 例如, 通过已获取的 LAC ID査找到该 LAC ID所属的 LAC号段, 并进一歩 査找到该 LAC号段对应的 LAC GROUP。
在具体实现中, UE的区域码所属的区域码集合与实际 APN的映射关系 为设计人员预置的, 图 3为图 2所示实施例所提供的网络设备中一种 UE与 实际 APN映射方式的示意图。如图所示,核心网(Core network)可以为 2G/3G 网络或 EPS网络, SGSN/MME负责移动性管理和信令处理, UGW9811华为 公司生产的统一分组数据网关设备, 集成了 GGSN、 S-GW和 P-GW网元的 功能, 为运营商降低了运营成本, 提高了网络部署能力, UE1和 UE2接入核 心网并映射到相应的实际 APN中, 该 APN映射规则例如可以为: 使用中国 移动互联网 (China Mobile Internet, 简称为: CMNET) APN激活的 UE, 如 果 UE所在位置区域属于 LAC GROUP A, 则映射到 APN City A; 如果用户 所在位置区域属于 LAC GROUP B, 则映射到 APN City B ; 通常地, 一个或 者多个 LAC GROUP对应到一个 APN中。 举例来说, UE1 的 LAC值为: 0*1111 , UE2的 LAC值为: 0*2111, UE1和 UE2的 LAC值都在 LAC GROUP 的 LAC号段中, A号段包括 0*1111, 0*1112, B号段包括 0*2111, 0*2112, 实际可以接入的 APN包括 City A和 City B, 因此, 根据上述 APN映射规则, UE1实际接入的 APN为 City A, UE2实际接入的 APN为 City B ;并且 City A 和 City B中都有预置的地址池, 例如分别可以为 City A ( 10.0.0.0/16)和 City B ( 10.1.0.0/16) 。
需要说明的是, 本实施例提供的网络设备, 同样可以为 2G/3G网络中的 SGSN或者 GGSN, 以及 CDMA网络中的 PDSN/HSGW。

进一歩地, 在上述实施例根据 UE的地理区域获取实际接入 APN的基础 上, 网络设备可以根据该 UE实际接入的 APN对其进行网络管理控制, 也就 是基于用户地理区域进行的网络管理控制; 需要说明的, 以下实施例中执行 管理控制的网络设备具体为 2G/3G网络中的 GGSN或者 EPS网络中的 P-GW。 其中, UE接入的实际 APN与 IP地址池有对应关系, 本实施例提供的网络设 备还可以包括: 地址分配模块 16, 用于从 IP地址池中为 UE分配 IP地址; 该网络设备还可以包括: 统计模块 17, 用于通过对该实际 APN下的数据流 量或者信令进行统计, 以获取针对地理区域范围内接入的 UE的数据流量统 计结果和信令统计。
更进一歩地, UE接入的实际 APN与配置信息对应, 该配置信息可以包 括: 接入 UE的数量、 使用带宽、 计费策略、 鉴权策略或业务控制策略; 相 应地, 该网络设备还包括: 控制模块 18, 用于根据上述配置信息对接入该实 际 APN的 UE进行控制;在具体实现中,该网络设备还可以包括发送模块 19, 用于将该 UE的用户信息发送到外部服务器,该用户信息可以包括该 UE与接 入的实际 APN 的对应关系, 该外部服务器例如为远程用户拨号认证系统 (Remote Authentication Dial In User Service, 简称为: RADIUS )月艮务器, 业 务报表服务器或呼叫历史服务器等, 使得该外部服务器对通过该网络设备上 报的用户数据进行基于实际 APN的分析,即可以获得基于用户地理区域的分 析数据。

在本实施例中, 当 UE 由于地理区域变化而重新发送的户激活请求时, 由于该请求中包括的 UE位置变化后的 ULI,即 UE的区域码发生变化,因此, P-GW需要重新确定该 UE的区域码所属的区域码集合。
