Description

终端访问业务的方法、 装置及系统 技术领域 本发明涉及移动通信技术领域, 尤其涉及一种终端访问业务的方法、 装 置及系统。 背景技术 目前基于移动互联网的大部分业务都釆用独立的 APN ( Access Point Name, 接入点名称)来实现, 典型的如中国移动使用的 CMWAP (WAP网的接入 网关)和 CMNET ( Internet接入网关)两个大众型 APN, 还有众多为集团客户 量身定做的 APN接入点。 CMWAP和 CMNET只是中国移动人为划分的两个 GPRS ( General Packet Radio Service, 通用分组无线服务)接入方式。 前者是 为手机 WAP上网而设立的,后者则主要是为 PC、笔记本电脑、 PDA等利用 GPRS 上网服务。它们在实现方式上并没有任何差别,但因为定位不同,所以和 CMNET 相比, CMWAP便有了部分限制, 资费上也存在差别, 简单理解: CMWAP相当于 局域网通过路由器上网, CMNET相当于直接给你一个外网 IP地址上网。 参见图 1,为现有技术 MS (终端)通过 GGSN( Gateway GPRS Support Node, 网关 GPRS支持节点)访问业务实体的结构示意图, 用户需要在终端上设置不 同的 APN, 在业务请求上携带 APN, GGSN根据不同 APN分发请求发送给不同的 业务实体, 从而在终端上实现各个业务。 当前 SGSN (Servicing GPRS Support Node, 服务 GPRS支持节点)对 APN 及 GGSN选择 ( APN激活) 的技术方案如下:
01、 接收用户上报的业务请求;
02、 判断业务请求中的 APN是否为空:
021、如果为空,则判断该用户是否为 HLR( Home Location Register): 归属位置寄存器)签约 APN用户:
0211、若是签约 APN用户,则进一步判断 HLR中是否仅有唯一的 APN: 02111、 若只有唯一的 APN, 则根据该唯一的 APN查询对应的 GGSN; 02112、 若 HLR中有两个以上 APN, 则拒绝激活。 0212、 若不是签约 APN用户, 则拒绝激活,
022、 如果不为空, 判断业务请求中的 APN是否为签约 APN:
0221、 若是签约 APN, 则才艮据该签约 APN查询对应的 GGSN;
0222、 若不是签约 APN, 则拒绝激活。 该方案规避了用户仅签约一个 APN但未设置 APN导致业务访问失败的场 景, 但无法规避用户存在多个签约 APN而未正确设置 APN导致访问业务失败 的场景。 多个 APN涉及的各个业务的处理流程如下: [1]访问企业业务 在终端上配置 APN为企业 APN (Enterprise APN), 并在访问请求上携带 Enterprise APN, GGSN通过分析访问请求获悉 Enterprise APN, 将业务请求 转发给 VPN (Virtual Private Network, 虚拟专用网络)路由器处理, 实现 企业业务的访问。
[2] 访问 MMS (Multimedia Messaging Service, 多媒体消息业务) 在终端上配置 APN为固 S APN, 并在访问请求上携带固 S APN, GGSN通过 分析访问请求获悉固 S APN, 将业务请求转发给固 SC (Multimedia Messaging Service Center, 多媒体消息业务中心)处理。
[3]访问 WAP (Wireless Application Protocol, 无线应用协议) 网站 在终端上配置 APN为醫 APN, 并在访问请求上携带醫 APN, GGSN通过 分析访问请求获悉 WAP APN, 将业务请求转发给 WAPGW处理。
[4]访问 Internet网站 在终端上配置 APN为 Internet APN, 并在访问请求上携带 Internet APN, GGSN通过分析访问请求获悉 Internet APN, 将业务请求转发给 Internet GW 处理。 本发明人在研究过程中发现, 现有终端只可以设定一个 APN配置, 这使 得用户在使用业务发生切换的过程中, 需要频繁修改终端配置, 如移动终端 在收发彩信时, 需要将 APN设定为 CMWAP, 同时还要设好正确的 WAPGW地址后 才能使用 MMS , 当用户想使用高速 Internet冲浪时, 必须重新设定接入点, 并删除 Proxy (代理)设置, 这个问题的存在妨碍了各类数据业务的推广, 并 降低了用户的业务体验。 发明内容 本发明提供一种终端访问业务的方法、 装置及系统, 在终端无需频繁更 改 APN即可实现访问各种 APN业务的目的。 为此, 本发明实施例釆用如下技术方案: 一种终端访问业务的方法, 包括:
GGSN或者位于所述 GGSN的下一级的网关接收终端用户发送的携带虚拟接 入点名称 VAPN或者不包括 APN的业务请求, 对所述业务请求实施深层包检查 DPI处理, 识别出业务类型; 所述 GGSN或所述网关将所述业务请求发送至所述业务类型对应的外部数 据网络。 一种终端访问业务的装置, 包括: 接收单元, 用于接收终端用户发送的携带 VAPN或者不包括 APN的业务请 求; 业务类型识别单元, 用于通过解析所述业务请求, 对所述业务请求实施 深层包检查 DPI处理, 识别出业务类型; 控制发送单元, 用于将所述业务请求发送至所述业务类型对应的外部数 据网络。 一种终端访问业务的系统, 包括终端、 网关设备和至少一个 APN功能实 体, 其中, 所述网关设备包括: 接收单元, 用于接收终端用户发送的携带 VAPN或者不包括 APN的业务请 求; 业务类型识别单元, 用于通过解析所述业务请求, 对所述业务请求实施 深层包检查 DPI处理, 识别出业务类型; 控制发送单元, 用于将所述业务请求发送至所述业务类型对应的外部数 据网络。 一种用户终端, 包括: 业务请求单元, 用于向 GGSN或位于所述 GGSN的下一级的网关发送携带 虚拟接入点名称或者不包括 APN的业务请求, 请求与 APN功能实体进行连接; 业务处理单元, 用于通过所述 GGSN或所述网关建立连接的外部数据网络 进行业务数据交换 由此, 本发明实施例通过 GGSN或其位于所述 GGSN的下一级的网关的业 务识别功能, 在移动终端不需要修改终端 APN配置的情况下, 可达到访问各 类移动数据业务的目的, 从而在简化了用户操作的基础上, 达到了访问不同
APN业务的目的, 有效提升了终端用户的业务体验, 同时, 促进了运营商的业 务推广。 附图说明 图 1为现有技术终端访问业务系统示意图; 图 2为本发明实施例终端访问业务的方法流程图; 图 3为本发明实施例终端访问业务系统示意图; 图 4为本发明实施例终端通过 GW实现业务访问的流程图; 图 5为本发明实施例 GW结构示意图。 具体实施方式 在本发明实施例中,仅在终端配置一个统一的 APN, 当用户访问不同业务 时, 不需要改变终端的 APN配置。 参见图 2 , 为本发明实施例终端访问业务的方法流程图, 包括:
S201 : GGSN或位于所述 GGSN的下一级的网关接收用户发送的携带 VAPN ( Vi r tua l APN, 虚拟 VPN )或者不包括 APN的业务请求, 通过对所述业务请 求实施 DPI处理, 识别出业务类型。 该位于所述 GGSN的下一级的网关可以称 为 GGSN的下游网关。 所述 VAPN不是实际的接入点名称或者 PROXY地址, 其作用主要在于实现 将业务请求发送到 GGSN上, 满足 3GPP规范或者其他规范的要求, 例如, 通 过在用户终端上配置该 VAPN, 并在 HLR上对该 VAPN签约, 实现将该不携带实 际接入点名称或者 PROXY地址的业务请求发送到对应的 GGSN上。 当然, 只要 在网络设备上配置对该虚拟 APN流或者空白 APN放通策略, 实现由 GGSN或者 其上游网关能够接收到业务请求, 通过 DPI识别出业务类型即可。
S202: GGSN或该网关将所述业务请求转发至所述业务类型对应的外部数 据网络。 与现有方案相比, 本发明实施例在核心网设备侧进行业务类型识别, 识 别出业务类型后将业务请求转发至相应的外部数据网络, 实现相应的 APN业 务, 在终端侧只需设置一个 VAPN, 或者约定不设置 APN, 从而不需要设置任 何 Proxy地址或者针对不同的业务手工切换不同的 APN。 在现有方案中(可参见图 1 ), 在 GGSN上主要进行认证和报文转发, 具体 地, 通过业务请求中携带的在终端上配置的 APN确定出目标功能实体, 然后 将业务请求转发给目标功能实体, 对于报文控制等操作是在各个功能实体上 进行的, 而在本发明实施例中, 在 GGSN下一级增加了一个 GW, 用以对业务请 求进行解析和控制, 也即, 执行各个功能实体的部分功能, 具体地通过数据 DPI ( Deep Packe t Inspect ion , 深层包检测), 识别出业务类型, 而不依赖 于业务请求中携带的 APN识别出业务类型, 从而无需在终端侧进行配置 APN, 也即简化了终端配置及变更 APN配置的操作。 参见图 3 , 为本发明实施例终端访问业务系统示意图, 与图 1相比, 其主 要改进在于在 GGSN下一级增加了网关 GW, 该 GW主要功能是业务识别, 进一 步, 还可实现 QoS ( Qua l i ty of Service , 服务质量)控制或者计费等功能。 图 3中的 GW对接收的业务请求进行透明处理, 即, 不改变报文源地址特 征, 具体的处理如下: 可以在进行 DPI检测之前, 针对企业用户的 VPN业务请求, 通过该企业 用户的 IP, 识别出该用户为特定的签约用户后, 将 VPN业务请求转发到特定 的路由平台 (例如 VPN路由器), 从而保证业务的安全性; 针对其他类型的业务请求, 实施 DPI , 获取业务类型后, 分别进行对应的 处理:
2. 1 针对 WAP1X请求, 转发至 WAPGW进行协议转换;
2. 2针对固 S请求,进行头增强操作,将用户部分 PDP信息(如 APN、 MS I SDN ) 增加到业务请求头中, 然后将业务请求发送至固 SC;
2. 3针对特定需要进行头增强的请求(如 RTSP请求, Rea l Time Streaming Protocol , 实时流传输协议), 增加相关的头后, 将业务请求发送到对应的业 务功能实体;
2. 4 针对普通的互联网业务请求, 直接将业务请求转发至对应的业务服 务器。 其中, DPI技术是一种基于应用层的流量检测和控制技术, 当 IP数据包、 TCP或 UDP数据流通过基于 DPI技术的带宽管理系统时,该系统通过深入读取 IP包载荷的内容来对 0SI七层协议中的应用层信息进行重组, 从而得到整个 应用程序的内容, 然后按照系统定义的管理策略对流量进行整形操作。 该实施 DPI以获取业务类型的步骤例如, DPI模块读取报文内容, 该内容 中包含业务的信息 (例如固 S , WAP , HTTP等等), 还可以进一步和本地的知 识库做对比, 以确认详细的业务类型信息。
3、 针对异常请求的处理: 与现有方案中各个业务功能实体处理各自业务相比, 本发明实施例中的 GW相当于各个业务功能实体中的调控器, 因此, 可针对某个异常请求在各个 业务实体中调控, 例如, 针对部分设定错误的 WAP请求, 通常其目的服务器 IP为特定的内网 IP, 此时, 修改目标 IP后发送至 WAPGW, 针对响应报文, 也 需修改源地址, 从而保证终端正确处理; 4、 根据业务请求解析出业务数据, 根据业务数据进行 QoS控制或者进行 计费等: 现有 QoS控制及计费可以分布在各个功能实体上,例如, MMSC或者 WAPGW 上,由于现有 GGSN无法识别具体业务数据,无法做到针对业务进行不同的 QoS 控制或计费, 而本发明实施例中, 由于 GW具有业务识别功能, 可将 QoS控制 及计费归结到该 GW上执行, 而不限于在各个业务功能实体上进行。 具体有关 QoS控制以及计费的具体实现可釆用现有技术中的方案,不是本发明实施例所 讨论的重点。 参见图 4 , 为本发明实施例终端通过 GW实现业务访问的流程图, 主要步 骤包括:
S401 : 针对目前现网通用的 APN业务, 终端上设置一个虚拟 APN名称, 如 VAPN, 而不需要设置任何 Proxy地址, 这个 VAPN可以包含如下 APN涉及的 业务, 即可以取代下面现网这些 APN:
Internet APN; MMS APN;
WAP APN; 企业用户 APN。
S402: 终端向 GGSN发送业务请求, 该请求中携带新增的 VAPN;
S403: GGSN从业务请求获取 VAPN; S404: 由于业务请求中包括 VAPN, 由此 GGSN可知是釆用虚拟 APN策略, 因此将业务请求转发至 GW; 或者, 可省略 S401 , 即, 在终端上不进行 APN配置, 继而在业务请求中 也不携带 APN,此时, 默认釆用 GW业务识别的策略, GGSN接收到业务请求后, 在 S4G4中进行认证等处理后, 直接将业务请求转发至 GW。
S405: GW根据业务请求, 识别出具体的业务类型, 执行相应的操作:
( 1 )通过与用户的签约关系识别出业务类型 例如, 通过与所述用户的签约关系, 识别出业务类型为 VPN业务, 然后 将 VPN业务请求转发至对应的虚拟专用网络路由器(VPN Route )。
( 2 )针对异常的业务请求, 根据预置策略对请求进行控制和处理。 例如, 当所述异常的业务请求为错误的 WAP请求时, 修改 WAP请求的目 标 IP, 然后将请求发送给 WAPGW。
