Description

数据传输方法及设备 技术领域
本发明涉及通信技术领域，尤其涉及一种数据传输方法及设备。
背景技术
数据服务器用于向终端设备提供数据服务器。目前，数据服务器通常部署在核心网中，且数据服务器和基站的距离较远。
在现有技术中，当终端设备需要从数据服务器中获取数据时，终端设备先与基站建立连接，并通过基站向数据服务器请求数据。在数据服务器接收到终端设备通过基站发送的数据请求时，数据服务器先将数据发送给基站，再由基站将数据发送给终端设备。由于数据服务器和基站的距离通常较远，在数据服务器向基站发送数据的过程中，通常需要经过多个交换接口才能将数据发送至基站，且数据服务器和基站之间的传输通道带宽受限，使得数据服务器给终端设备下发数据缓慢，使得数据服务器向基站发送数据的时延较大，进而导致终端设备从数据服务器获取数据的时延较大。
发明内容
本发明实施例提供一种数据传输方法及设备，用于降低终端设备从数据服务器获取数据的时延。
第一方面，本发明实施例提供一种数据传输方法，该方法的执行主体为基站，在基站接收到终端设备发送的数据获取请求之后，基站确定该数据获取请求对应的本地服务器和远端服务器，其中，本地服务器与基站之间的距离小于第一预设距离，远端服务器与基站之间的距离大于第二预设距离。基站向本地服务器请求获取数据获取请求对应的数据信息，并向终端设备发送在本地服务器获取得到的数据信息。同时，基站还向远端服务器请求下载数据信息，以使远端服务器向核心网中的计费与监听接口发送数据信息，以使计费与监听接口对数据信息进行计费及监听。
在上述过程中，基站接收到的终端设备的数据获取请求之后，基站同时 向本地服务器和远端服务器发送数据获取请求，以使本地服务器和远端服务器可以同步下发相同的数据信息。远端服务器在先发数据信息时，远端服务器下发的数据信息会经过核心网以使核心网中的计费与监听接口还可以对数据信息进行正常的计费监听。由于本地服务器和基站的距离较近，使得基站可以快速获取本地服务器下发的数据信息，提高了本地服务器向基站发送数据信息的效率，进而提高终端设备获取数据信息的效率。
在一种可能的实施方式中，当数据获取请求中包括的内容不同时，基站确定数据获取请求对应的本地服务器和远端服务器的方式也不同。可选的，可以包括以下两种可行的实现方式：
一种可行的实现方式：数据获取请求中包括待访问服务器的标识。
相应的，基站可以根据待访问服务器的标识，确定本地服务器和远端服务器。在该种可行的实现方式中，基站可以根据数据获取请求快速获取待访问服务器的标识，以使基站可以快速确定本地服务器和远端服务器。
另一种可行的实现方式，数据获取请求中包括待请求数据对应的统一资源定位符URL地址；相应的，基站可以对URL地址进行解析，获取待访问服务器的标识，并根据待访问服务器的标识，确定本地服务器和远端服务器。
在另一种可能的实施方式中，在向本地服务器请求获取数据获取请求对应的数据信息之前，基站还可以获取基站中设置的白名单列表，白名单列表中包括至少一个服务器的标识，并确定白名单列表中包括服务器的标识，白名单列表中的服务器的标识为允许对服务器对应的本地服务器进行访问的服务器的标识。这样，可以保证基站对数据获取请求处理的安全性。
在另一种可能的实施方式中，可选的，基站可以通过如下两种可行的实现方式向本地服务器请求获取数据获取请求对应的数据信息：
一种可行的实现方式：基站具备数据分流功能。
在该种可行的实现方式中，通过基站的数据分流功能对数据获取请求进行协议转换，以使本地服务器可识别进行协议转换后的数据获取请求，向本地服务器发送协议转换后的数据获取请求，接收本地服务器发送的数据信。
另一种可行的实现方式：基站与数据分流服务器独立设置。
在该种可行的实现方式中，向基站对应的数据分流服务器发送数据获取请求，以使数据分流服务器对数据获取请求进行协议转换，并向本地服务器 发送协议转换后的数据获取请求，本地服务器可识别协议转换后的数据获取请求，接收数据分流服务器发送的数据信息，数据信息为本地服务器向数据分流服务器发送的。在上述过程中，基站和LBO服务器为两个独立的设备，这样，便于对LBO服务器的部署。
第二方面，本发明实施例提供一种数据传输方法，该方法的执行主体为远端服务器，在远端服务器接收到基站发送的数据下载指令之后，获取基站请求的数据信息，并通过预设接口向业务吸收单元发送数据信息，以使业务吸收单元终止发送数据信息，预设接口用于对数据信息进行计费及监听。
在上述过程中，基站接收到的终端设备的数据获取请求之后，基站同时向本地服务器和远端服务器发送数据获取请求，以使本地服务器和远端服务器可以同步下发相同的数据信息。远端服务器在先发数据信息时，远端服务器下发的数据信息会经过核心网以使核心网中的计费与监听接口还可以对数据信息进行正常的计费监听。由于本地服务器和基站的距离较近，使得基站可以快速获取本地服务器下发的数据信息，提高了本地服务器向基站发送数据信息的效率，进而提高终端设备获取数据信息的效率。
在一种可能的实施方式中，远端服务器可以通过如下可行的实现方式获取基站请求的数据信息：远端服务器接收本地服务器发送的数据同步指令，并根据数据同步指令，获取数据信息。
在另一种可能的实施方式中，数据同步指令包括数据信息对应的哈希值；相应的，基站可以在数据同步指令中获取哈希值，并获取哈希值对应的数据信息。

具体实施方式
图1为本发明提供的数据传输方法的应用场景示意图。请参见图1，包括终端设备101、基站102、本地服务器103、远端服务器104、计费与监听接口105、业务吸收模块106、以及服务网关(Serving Gate Way，简称SGW)和PGW(PDN Gate Way，PDN网关)107。终端设备101可以为手机、电脑等通信设备。本地服务器103和远端服务器104可以向终端设备101提供相同的服务，其中，远端服务器104与基站102的距离通常较远，本地服务器103与基站102的距离通常较近。
在本申请中，当基站102接收到终端设备101发送的数据获取请求之后，基站102同时向本地服务器103和远端服务器104请求数据。其中，基站102具有本地数据分流(Local Break Out，简称LBO)功能，或者，在基站102附近设置LBO服务器，以使基站102可以通过自带的LBO功能或者LBO服务器向本地服务器103请求数据。基站102在向远端服务器104请求数据时，基站102向远端服务器104发送的消息需要经过核心网。
在本地服务器103和远端服务器104接收到基站102发送的数据请求之后，本地服务器103和远端服务器同步进行数据下发。本地服务器103下发的数据经过基站102的LBO功能或者LBO服务器发送至基站102，基站102将本地服务器103下发的数据发送至终端设备101。远端服务器104下发的数据经过SGW/PGW107，以使SGW/PGW107对数据进行正确的转发，下发的数据再经过核心网的计费与监听接口105，以使计费与监听接口105可以对终端设备101请求的数据进行计费以及监听，下发的数据经过计费与监听接口105之后流向业务吸收模块106，业务吸收模块106终止下发数据，以避免远端服务器104下发的数据发送至终端设备101，进而避免终端设备101接收到重复的数据。
在本申请中，由于本地服务器103与基站102的距离较近，以使在终端设备101通过基站请求数据时，本地服务器103可以快速向基站102发送请求的数据，以使基站102可以快速向终端设备反馈请求的数据，进而降低终端设备101请求数据的时延。同时，由于远端服务器104可以和本地服务器103同步下发数据，以使计费与监听接口可以对终端设备101接收到的数据进行计费及监听。
下面，通过具体实施例对本申请所示的技术方案进行详细说明。需要说明的是，下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。
图2为本发明提供的数据传输方法的流程示意图一。请参见图2，该方法可以包括：
S201、终端设备向基站发送数据获取请求。
本发明所示的技术方案适用于终端设备向数据服务器获取任意数据的过程，尤其适用于终端设备向数据服务器获取数据量较大的数据的过程，例如，终端设备向视频服务器获取视频数据的过程等。
当用户需要在终端设备中进行数据查看时，用户可以在终端设备中输入预设指令，以使终端设备向基站发送数据获取请求。例如，当用户需要在终端设备中观看视频时，用户可以对需要观看的视频对应的“观看”按钮进行点击操作，以使终端设备向基站发送用于请求视频数据的数据获取请求。
S202、基站根据数据获取请求，确定数据获取请求对应的本地服务器和远端服务器。
可选的，基站可以根据如下两种可行的实现方式确定数据获取请求对应的本地服务器和远端服务器：
一种可行的实现方式：
数据获取请求中包括待访问服务器的标识；相应的，基站可以根据待访问服务器的标识，确定本地服务器和远端服务器。
另一种可行的实现方式：
数据获取请求中可以包括待请求数据对应的URL地址；相应的，基站可以对URL地址进行解析，获取待访问服务器的标识，并根据待访问服务器的标识，确定本地服务器和远端服务器。例如，假设URL地址为： http：//abc.com/index.html，则基站可以在该URL地址中获取待访问服务器的表示为abc。
可选的，基站在确定得到的待访问服务器的标识之后，基站可以根据待访问服务器的标识，确定本地服务器的地址和远端服务器的地址，并根据本地服务器的地址，与本地服务器通信，根据远端服务器的地址，与远端服务器通信。
可选的，在执行S202之前，基站可以先获取预先设置的白名单列表，并判断白名单列表中是否包括待访问服务器的标识，若是，则执行S202-S212；若否，则根据现有技术中的执行过程对终端设备发送的数据获取请求进行处理。其中，白名单列表中包括至少一个服务器的标识，白名单列表中的服务器的标识为允许对服务器对应的本地服务器进行访问的服务器的标识。
需要说明的是，在S202之后，基站同时向本地服务器和远端服务器发送数据获取请求，因此，S203和S207同时执行。
S203、基站向本地服务器发送数据获取请求。
基站获取本地服务器的地址，并根据本地服务器的地址，向本地服务器发送数据获取请求。
基站向本地服务器发送数据获取请求时，不经过运营商的核心网络，为了保证基站可以成功的向本地服务器发送数据获取请求，可以在基站中集成LBO功能，或者在基站附近设置具有LBO功能的LBO服务器，以使基站可以通过LBO服务器向本地服务器发送数据获取请求。
S204、本地服务器根据数据获取请求，获取数据信息。
在本地服务器接收到数据获取请求之后，本地服务器根据数据获取请求获取数据信息。可选的，数据获取请求中可以包括请求数据的标识，以使本地服务器可以根据请求数据的标识获取数据信息。可选的，数据获取请求中可以包括用于指示请求数据的URL地址，以使本地服务器可以根据URL地址获取数据信息。
例如，假设终端设备需要请求视频数据，则终端设备发送的数据获取请求中可以包括该视频数据的URL地址，以使本地服务器可以根据视频数据的URL地址，获取视频数据。
可选的，为了保证远端服务器和本地服务器可以同步下发相同的数据信 息，在本地服务器获取数据信息之后，可以根据安全哈希算法(Secure Hash Algorithm，简称SHA)，生成哈希值，并向远端服务器发送生成的哈希值，以使远端服务器可以根据该哈希值获取相同的数据信息。
S205、本地服务器向基站发送数据信息。
在本地服务器获取得到数据信息之后，由于本地服务器向基站发送数据信息时不经过运营商的核心网，为了保证本地服务器可以将数据信息发送至基站，本地服务器可以先向LBO服务器发送数据信息，再由LBO服务器向基站发送该数据信息。或者，可以在基站中集成LBO功能，以使基站可以通过LBO功能成功的接收本地服务器发送的数据信息。
S206、基站向终端设备发送数据信息。
S207、基站向远端服务器发送数据获取请求。
需要说明的是，S203和S207同时执行。
基站获取远端服务器的地址，并根据远端服务器的地址，向远端服务器发送数据获取请求。
S208、远端服务器根据数据获取请求，获取数据信息。
可选的，在远端服务器接收到数据请求之后，可以直接根据数据获取请求获取数据信息。
可选的，为了保证远端服务器和本地服务器可以同步下发相同的数据信息，远端服务器可以接收本地服务器发送的、本地服务器获取的数据信息对应的哈希值，远端服务器根据哈希值，获取与本地服务器获取的数据信息相同的数据信息。
需要说明的是，在S208之后，远端服务器同时向计费与监听接口和业务吸收模块发送数据信息，即，S209与S210同时执行。
S209、远端服务器向计费与监听接口发送数据信息。
计费与监听接口通常为运营商在核心网部署的接口，一个运营商在一个区域通常只部署一个计费与监听接口。由于本地服务器和远端服务器同步发送相同的数据信息，因此，计费与监听接口相当于可以对发送至终端设备的数据信息进行计费及监听。
S210、远端服务器向业务吸收模块发送数据信息。
可选的，一个远端服务器可以对应一个业务吸收模块，远端服务器可以 向其对应的业务吸收模块发送数据信息。
S211、业务吸收模块终止发送数据信息。
可选的，业务吸收模块可以部署在核心网的通用服务器中，业务吸收模块用于终止发送计费与监听接口发送的数据信息，这样，可以避免终端设备接收到远端服务器发送的数据信息，以避免终端设备接收到重复的数据信息。
本发明实施例提供的数据传输方法，在基站侧设置有本地服务器，在远端服务器侧设置有计费与监听接口和业务吸收模块，本地服务器和远端服务器可以向终端设备提供相同的服务。在基站收到终端设备的数据获取请求之后，基站同时向本地服务器和远端服务器发送该数据请求，以使本地服务器和远端服务器可以同步下发相同的数据信息。本地服务器下发的数据信息可以快速发送给基站，并由基站发送给终端设备；计费与监听接口可以对远端服务器下发的数据信息进行计费及监听，并由业务吸收模块终止对该数据信息进行继续下发，进而避免终端设备接收到相同的数据信息。在上述过程中，由于本地服务器和远端服务器可以同步下发相同的数据信息，使得远端服务器侧的计费与监听接口还可以对终端设备接收的数据信息进行正常的计费监听，同时，由于本地服务器和基站的距离较近，提高了本地服务器向基站发送数据信息的效率，进而提高终端设备获取数据信息的效率。
在图2所示实施例的基础上，基站可以自带数据分流功能，以使基站可以对数据获取请求进行协议转换。当然，也可以在基站附近设置具有数据分流功能的LBO服务器，以使LBO服务器可以对数据获取请求进行协议转换。下面，通过图3-图4所示的实施例，对上述两种可行的实现方式进行详细说明。
图3为本发明实施例提供的对数据获取请求进行协议转换方法的流程图一。请参见图3，该方法可以包括：
S301、通过基站的数据分流功能对数据获取请求进行协议转换，以使本地服务器可识别进行协议转换后的数据获取请求。
在图3所示的实施例中，在基站中设置有数据分流功能，以使基站可以对数据获取请求进行协议转换，将数据获取请求转换为本地服务器可识别的形式。
数据获取请求的初始格式如表1所示，该数据获取请求为基于GPRS隧 道协议(GPRS Tuneling protocol，简称GTP-U)协议的物理层信令。

其中，表1和表2所示的格式的对应关系如图3A所示。图3A为本发明实施例提供的协议格式对应关系图。请参见图3A。转换前协议的GTP-U字段对应转换后协议的IP字段，转换前协议的UDP字段、IP字段、及MAC字段对应转换后协议的MAC字段。
S302、向本地服务器发送协议转换后的数据获取请求。
基站对数据获取请求进行协议转换之后，向本地服务器发送协议转换后的数据获取请求。
本地服务器接收到协议转换后的数据获取请求之后，本地服务器对数据获取请求进行解析，并获取数据获取请求对应的数据信息，并向基站发送数据信息。
S303、接收本地服务器发送的数据信息。
在本地服务器向基站发送数据信息时，本地服务器发送的数据信息的格式如表2所示，在基站接收到表2所示格式的数据信息时，基站根据LBO功 能对数据信息进行协议转换，以将数据信息转换为表1所示的格式。
在图3所示的实施例中，基站通过LBO功能对数据获取请求的进行协议转换，使得基站可以成功向本地服务器发送数据获取请求，且本地服务器可以识别协议转换后的数据获取请求。

S401、向基站对应的数据分流服务器发送数据获取请求，以使数据分流服务器对数据获取请求进行协议转换，并向本地服务器发送协议转换后的数据获取请求，本地服务器可识别协议转换后的数据获取请求。
在图4所示的实施例中，数据分流服务器(LBO服务器)设置在基站附近，当基站需要向本地服务器发送数据获取请求时，基站先向LBO服务器发送数据获取请求。
LBO服务器对接收到的数据获取请求进行协议转换，其中，LBO服务器对数据获取请求进行协议转换的过程可以参见图3所示实施例，此处不再进行赘述。
在LBO服务器对数据获取请求进行协议转换之后，LBO服务器向本地服务器发送协议转换后的数据获取请求。
S402、接收数据分流服务器发送的数据信息，数据信息为本地服务器向数据分流服务器发送的。
在本地服务器根据协议转换后的数据获取请求获取得到数据信息之后，本地服务器将数据信息发送给LBO服务器。其中，本地服务器向LBO服务器发送的数据信息的格式如表2所示，LBO服务器对本地服务器发送的数据信息进行协议转换，协议转换后的数据信息的格式如表1所示，LBO服务器向基站发送协议转换后的数据信息。
在图4所示的实施例中，基站和LBO服务器为两个独立的设备，这样，便于对LBO服务器的部署。
在上述实施例的基础上，下面，以LBO服务器对数据获取请求进行协议转换的过程为例，通过具体示例，对上述实施例所示的技术方案进行详细说明。
