Description

数据传送方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种数据传送方法及装置。
背景技术
传统的无线网络数据交换，都把基站的数据回传到核心网，再由核心网发送基站，即使两个用户再同一个基站下，也需要回传到核心网转发。当网络演进到长期演进(Long Term Evolution，简称为LTE)时代，数据流量越来越大，传统核心网的转发模式也不合适网络的发展方向了。
LTE提出异构网络(Heterogeneous Network，简称为HN)的概念，从而演进了一些新技术，第三代合作项目(3rd Generation Partnership Project，简称为3GPP)也对此技术进行专门的研究，比如本地业务交换本地IP接入(Local IP Access，简称为LIPA)，以及数据可选IP业务分流(Selected IP Traffic Offload，简称为SIPTO)等，将本地或者低价值的数据业务直接交换，或分流到Internet，避免大量低价值的业务对核心网的冲击。
LIPA是基于家庭级基站(Home eNodeB，简称为HeNB)网络提出的，其核心思想是将本地网络的通信数据直接从HeNB就分流出去，从而减轻了核心网络的负荷和传输成本。LIPA技术可以进一步演化为区域网的概念，即在一个有限的区域部署一个本地的无线网络，无线网络用户在认证后访问本地区域网络资源，也可以访问Internet资源，访问本地网络不需要计费或者另外计费，用户可以不更换终端访问企业内网，只需要换一个访问节点名称(Access Point Name，简称为APN)即可。
发明人发现，区域内部有线网络组网复杂，需要隔离内部用户，把不同用户划分到不同的区域网中，例如，划分到不同的虚拟本地网络(Virtual Local Area Network，简称为VLAN)。但是，在相关技术中并没有考虑不同用户访问不同区域网的问题。

步骤S104，该LGW根据该服务质量在该用户设备和该用户设备的IP地址对应的该区域网之间进行数据传送。
通过上述步骤，根据服务质量在该用户设备和该用户设备的IP地址对应的该区域网之间进行数据传送，从而可以根据IP地址和该IP地址能够接入的区域网、以及接入该区域网的服务质量的对应关系控制用户设备的访问权限，解决了相关技术中并没有考虑不同用户访问不同区域网的问题，不同用户根据分配的IP地址访问不同的区域网。
为了更加安全，该配置信息可以是在认证完成之后发送的，对用户设备的认证可以有多种方式，例如，在而一个可选的实施方式中，在LGW根据接收到的该配置信息为该用户设备分配IP地址之前，该LGW可以将用于认证该用户设备的认证信息转发给认证服务器，由该认证服务器对该认证信息进行认证，该LGW接收该认证服务器对该认证信息进行认证后发送的该配置信息，其中，该认证完成信息中可以包括：为该用户设备分配的接入IP地址、以及该IP地址能够接入的区域网、以及接入该区域网的服务质量。
在LGW将用于认证该用户设备的认证信息转发给认证服务器之前，该LGW还可以接收来自核心网的该认证信息，其中，该认证信息是该用户设备选择区域网接入点名称之后输入的。
在另一个可选实施方式中，在该服务质量中包括无线带宽资源的信息的情况下，该LGW将该无线带宽资源的信息发送给基站，以使该基站根据该无线带宽资源的信息进行调度。
根据该服务质量在该用户设备和该用户设备的IP地址对应的该区域网之间进行数据传送的方式可以有一种或者多种，在一个可选的实施例中，LGW根据该服务质量在该用户设备和该用户设备的IP地址对应的该区域网之间进行数据传送可以包括：该LGW根据该服务质量对该用户设备的IP地址分配网口带宽，并根据该网口带宽在该用户设备和该用户设备的IP地址对应的该区域网之间进行数据传送。
根据该服务质量在该用户设备和该用户设备的IP地址对应的该区域网之间进行数据传送的方式可以有一种或多种，在一个可选的实施例中，LGW根据该服务质量在该用户设备和该用户设备的IP地址对应的该区域网之间进行数据传送可以包括：该LGW在对应的IP报文中的DSCP字段设置为该服务质量指示的值或者在VLAN报文中的COS字段设置为该服务质量指示的值，在该用户设备和该用户设备的IP地址对应的该区域网之间进行数据传送。
用户设备不在服务区的情况下，LGW接收到该用户设备不在服务范围的通知，并删除该对应关系，从而释放资源，节约了储存空间。

第三接收模块82，设置为接收到该用户设备不在服务范围的通知；

下面结合可选实施例对本发明实施进行进一步说明。
LIPA引入了一个本地网关(Local Gateway，简称为LGW)的网络逻辑节点，HeNB数据汇聚到LGW后再做分流处理，实际应用中，LGW和HeNB可以是同一物理实体，也可以为单独物理实体。
用户接入区域网，用户在UE上选择接入区域网APN，输入用户名密码，核心网将区域网的用户认证信息给LGW，LGW转发给认证服务器认证。
用户鉴权，LGW将UE请求数据发送给认证服务器，认证协议一般为标准的Radius协议(但不限于Radius协议)，LGW发送给认证服务器的认证信息包括身份唯一标示(Identity，简称为UE ID)，一般为全球用户识别卡(Universal Subscriber Identity Module，简称为USIM)的国际移动用户识别码(International Mobile Subscriber Identification Number，简称为IMSI)号，或者手机号码、或者手机号码、UE接入APN的用户名、密码等。
服务质量的分配，认证服务器收到认证请求后，根据预先配置的信息，返回给UE接入本地网络的用户IP、服务质量等信息。服务质量主要包括无线服务质量和传输有 线传输质量，有线传输质量集中表现于有线网络的DSCP，如果配置有VLAN，还有VLAN的COS值，LGW可以根据配置的UE IP做优先级调度。
本地网关处理，UE只支持标准的IP报文，LGW根据保存的UE、IP以及服务质量的映射关系时，将对应IP报文的DSCP字段设置为认证服务器的配置值，同样，如果支持VLAN，也在VLAN头中打上对应的COS字段。
如果LGW本身支持根据IP分配网口带宽，可以根据认证服务器配置的带宽给UE分配不同的带宽资源。
如果认证服务器支持配置无线带宽资源，LGW把对应带宽资源发生给HeNB，HeNB根据配置的无线带宽资源做空口调度。
释放资源，当UE切换或离开基站时，LGW同步删除之前保留的UE和IP、服务质量的映射表。
对于某大型企业，有高级客户来访问，为了提升客户的满意度，在高级客户访问区域网时，需要配置更高的优先级，在多个用户同时访问网络时，优先保证高级客户的服务质量。
图9是根据本发明优选实施例的区域网组网的示意图，如9所示，区域网是在一个有限的区域部署一个本地的无线网络，可以是不同公司，或者不同楼层的网络，用户接入区域网内部不需要更换UE，也不需要基站更改频段，只需要修改接入的APN。
区域网需要核心网支持本地交换等功能，区域网认证服务器放置在区域网内，UE的接入权限，接入IP，服务质量等分配都由区域网认证服务器来分配。
图10是根据本发明实施例的UE接入区域网的示意图，如图10所示，UE选择区域网APN，用户输入认证信息后，核心网将区域网的用户认证信息给LGW，LGW转发给认证服务器认证，用户接入认证包括以下步骤：
步骤S1002，LGW把认证数据转发给认证服务器，认证服务器认证用户信息，认证通过后，分配给UE的接入权限和预先规划的资源，主要包括UE的用户IP、服务质量等信息；
步骤S1004，LGW收到认证信息后，将用户IP分配给对应UE，保存对应UE和分配IP、服务质量等映射列表，如果配置有无线空口服务质量，则发送给HeNB；
步骤S1006，LGW接收到UE发送给区域网的数据，查询保存的UE和IP、服务质量IP对应关系，封装DSCP和COS值在IP头或VLAN头，然后转发给不同的区域网；如果LGW支持基于IP的网口带宽资源分配，则根据认证服务器分配的带宽，给不同UE用户分配不同的带宽；如果用户配置了基于无线空口资源的服务质量，则HeNB根据配置给不同UE分配不同无线空口资源；
步骤S1008，如果UE切换，离开基站，或者掉电等，HeNB检测出UE不在服务范围后通知LGW删除之前对应的UEID、IP、服务质量等对应关系，同时如果HeNB配置了无线服务质量，则删除对应的空口无线资源。
步骤S1010，UE访问本地网络。
本可选实施例中的LGW需要实现以下功能，需要说明的是，以下的功能可以通过不同的模块实现。
认证功能，LGW需要封装认证信息报文给认证服务器，完成UE接入的认证功能。
UE和IP、服务质量映射列表：LGW需要保存每个接入区域网UE对应的IP和服务质量的映射关系，UE报文转发给区域网时查表用。
服务质量控制功能，主要控制给UE的IP报文封装DSCP值，给VLAN封装COS值，如果LGW支持基于IP的带宽分配，则在LGW网口给不同UE分配不同网络带宽资源。
对于HeNB，需要处理认证服务器配置的无线侧服务质量，完成空口无线资源分配。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
