Description

一种数据传输方法及设备 技术领域
本发明涉及通信领域，尤其涉及一种数据传输方法及设备。
背景技术
随着网络互连协议第四版(英文全称：Internet Protocol version4，英文简称：IPv4)地址资源日益紧张，移动通信网络不断向支持网络互连协议第六版(英文全称：Internet Protocol version 6，英文简称：IPv6)地址过渡。第三代合作伙伴计划(英文全称：3rd Generation Partnership Project，英文简称：3GPP)协议支持给用户设备(英文全称：User Equipment，英文简称：UE)分配双栈地址，即为UE分配一个IPv4地址和/或一个IPv6地址。
当UE和服务器均支持双栈地址和多路径传输控制协议(英文全称：Multi-Path Transmission Control Protocol，英文简称：MPTCP)时，在一次业务执行过程中，UE可以获取一个IPv4地址和一个IPv6地址，与服务器的IPv4地址和IPv6地址建立两个子流(英文全称：Subflow)，通过两个子流与服务器进行数据传输。
然而，当服务器不支持双栈地址时，UE只能通过服务器所支持的IP地址类型访问服务器，不能通过另一IP地址访问服务器。例如，一个服务器只支持IPv4地址，那么UE只能通过IPv4地址访问服务器，而不能通过IPv6地址访问服务器，导致数据传输速率低。
发明内容
本申请提供一种数据传输方法及设备，能够在服务器不支持双栈地址时，利用UE的双栈地址访问服务器，提高UE与服务器之间的数据传输速率。
为达到上述目的，本申请采用如下技术方案：
第一方面，提供一种数据传输方法，MPTCP代理接收用户设备UE发送的访问请求消息之后，根据访问请求消息所携带的服务器的IP地址与服务器建立第一连接，根据访问请求消息所携带的第一IP 地址与UE建立第二连接，并将第二连接与第一连接建立关联，以完成UE与服务器之间的报文转发。其中，第二连接为MPTCP连接，包括UE使用第一IP地址与MPTCP代理建立的第一子流，以及UE使用第二IP地址与MPTCP代理建立的第二子流。UE可以利用双栈地址，通过MPTCP代理访问服务器，从而提高了UE与服务器之间的数据传输速率。
结合第一方面，在一种可能的实现方式中，MPTCP代理可以根据UE的业务数据量对第一连接和第二连接各自包括的子流的数量进行动态调整，以调节UE与服务器之间的数据传输速率。
第二方面，提供一种数据传输设备，包括计算机可读介质，用于存储本申请方案的程序代码，所述程序代码包括用于执行第一方面所提供的数据传输方法的指令。
第三方面，提供另一种数据传输设备，包括处理器、收发器、存储器及总线，所述处理器、所述收发器以及所述存储器通过所述总线相互连接；用于执行本申请第一方面所提供的数据传输方法的程序代码保存在所述存储器中，并由所述处理器来控制执行。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为对本发明的实施例所提供的数据传输方法应用场景的说明示意图；
图2为本发明的实施例所提供的数据传输方法流程示意图；
图3为本发明的实施例所提供的一种数据传输装置的结构示意图；
图4为本发明的实施例所提供的另一种数据传输装置的结构示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的实施例提供一种数据传输方法，应用于多路径传输控制协议(英文全称：Multi-Path Transmission Control Protocol，英文简称：MPTCP)代理。结合图1所示的应用场景，用户设备(英文全称：User Equipment，英文简称：UE)通过分组数据网络网关(英文全称：packet data network gateway，英文简称：PGW)以及多路径传输控制协议(英文全称：Multi-Path Transmission Control Protocol，英文简称：MPTCP)代理访问服务器。UE接入移动网络后，与PGW建立连接，PGW设备可以包括MPTCP代理或者两者各自独立。当PGW设备包括MPTCP代理时，PGW可以根据UE和服务器的IP地址类型选择开启或者关闭MPTCP代理的功能。具体的，如果UE从PGW获取的IP地址与服务器的IP地址为同类型的IP地址，例如同为IPv4地址或者IPv6地址，则PGW无需开启MPTCP代理的功能。如果UE从PGW获取两个IP地址，包括一个IPv4地址和一个IPv6地址，则PGW开启MPTCP代理的功能。当PGW设备与MPTCP代理各自独立时，MPTCP代理位于PGW与服务器之间。
本发明所提供的数据传输方法涉及两种IP地址的类型，本发明的实施例中仅以IPv4地址和IPv6地址两种类型的IP地址为例进行说明。当然这并不代表本发明仅适用于IPv4地址和IPv6地址的情形。
UE获取的两个不同类型的IP地址，包括一个IPv4地址和一个IPv6地址，并利用这两个IP地址与MPTCP代理建立MPTCP连接。 MPTCP代理可以和服务器建立普通的TCP连接，或者建立MPTCP连接。
MPTCP代理与服务器之间的MPTCP连接，和，MPTCP代理与UE之间的MPTCP连接的区别在于，MPTCP代理与UE建立的MPTCP连接，包括通过IPv4地址建立的子流(英文全称：Subflow)，和通过IPv6地址建立的子流。而MPTCP代理与服务器建立的MPTCP连接，只包括通过IPv4地址或者IPv6地址其中的一种建立的子流。例如服务器只支持IPv4地址，那么MPTCP代理与服务器之间的MPTCP连接只包括通过IPv4地址建立的子流。
本发明的实施例中，分别以第一IP地址和第二IP地址来描述UE获取的两个不同类型的IP地址，第一IP地址和第二IP地址其中之一为IPv4地址，另一为IPv6地址。服务器的IP地址为IPv4地址或者IPv6地址。本发明的实施例以第一IP地址和服务器的IP地址为IPv4地址、第二IP地址为IPv6地址的情况为例进行说明。
实施例
本发明的实施例提供一种数据传输方法，应用于MPTCP代理，参照图2所示，包括以下步骤：
201、接收用户设备UE发送的访问请求消息。
UE向PGW发送访问请求消息，请求访问服务器，访问请求消息包括服务器的IP地址以及UE的第一IP地址，第一IP地址与服务器的IP地址为相同类型的IP地址，即均为IPv4地址。
PGW将访问请求消息转发至MPTCP代理，或者只将服务器的IP地址以及第一IP地址发送至MPTCP代理。以便于MPTCP代理分别与服务器和UE建立连接。
202、根据服务器的IP地址，与服务器建立连接。
MPTCP代理与服务器之间建立连接，包括以下两种情况。
第一种情况，服务器不支持MPTCP，此时MPTCP代理根据服务器的IP地址，使用访问IP地址与服务器建立TCP连接。其中，访问IP地址与服务器地址为相同类型的IP地址，即IPv4地址。
访问IP地址可以为UE的第一IP地址，即MPTCP代理接收到UE发送的访问请求消息之后，使用访问请求消息中携带的第一IP地址与服务器建立TCP连接。
当然，访问IP地址还可以是其它的IPv4地址，例如访问IP地址是预先为MPTCP代理配置的IP地址。
第二种情况，服务器支持MPTCP，此时MPTCP代理根据服务器的IP地址，与服务器建立MPTCP连接，以提高MPTCP代理与服务器之间的数据吞吐率。
MPTCP代理与服务器之间的MPTCP连接，可以包括至少一个子流。其中一个子流对应一个IP地址对，一个IP地址对包括一个MPTCP代理端的IP地址和一个服务器端的IP地址，其中MPTCP代理端的IP地址，是指MPTCP代理与服务器建立子流时所使用的IP地址，服务器端的IP地址，是指服务器与MPTCP代理建立子流时所使用的IP地址。由于服务器只支持一种IP地址类型，MPTCP代理端的IP地址与服务器端的IP地址均为相同类型的IP地址。
可选的，服务器的IP地址的数量为1，即服务器的IP地址只包括访问请求消息中所包括的服务器的IP地址。这种情况下，MPTCP代理使用至少一个访问IP地址与服务器建立子流。其中访问IP地址与服务器的IP地址为相同类型的IP地址。当访问IP地址的数量为1时，访问IP地址可以是第一IP地址。当访问IP地址的数量大于1时，当访问IP地址还可以包括预先为MPTCP代理配置的IP地址。结合表一所示，一个子流对应的IP地址对中，MPTCP代理端的IP地址可以为第一IP地址，或者访问IP地址，服务器端的IP地址均相同，为访问请求消息中所包括的服务器的 IP地址，表一中用IP地址A表示。
表一
Figure PCTCN2015097596-appb-000001
可选的，服务器的IP地址的数大于1，MPTCP代理根据访问请求消息中所包括的服务器的IP地址，使用第一IP地址与服务器建立第一个子流之后，服务器通过该子流向MPTCP代理发送其它的IP地址。这种情况下，MPTCP代理与服务器在第一个子流基础上再建立其它子流。结合表二，不同子流对应的IP地址对中，服务器端的IP地址可以不同。
表二
Figure PCTCN2015097596-appb-000002
进一步可选的，当服务器的IP地址的数大于1，且没有为MPTCP代理预先配置访问IP地址的应用场景中，MPTCP代理端的IP地址可以只包括第一IP地址这一个IP地址，MPTCP代理仍旧可以与服务器之间建立多个子流，不同子流对应的IP地址对中，MPTCP代理端的IP地址均为第一IP地址，服务器端的IP地址各部不同。
203、根据第一IP地址，与UE建立第二连接。
其中第二连接为MPTCP连接。第二连接包括第一子流和第二子流。结合表三，对MPTCP代理与UE建立第一子流和第二子流的过程说明如下：
表三
Figure PCTCN2015097596-appb-000003
UE支持双栈地址，UE的IP地址包括第一IP地址和第二IP地址，第一IP地址和第二IP地址为不同类型的IP地址。本实施例中第一IP地址为IPv4地址，第二IP地址为IPv6地址。服务器的IP地址可以为IPv4地址或者IPv6地址，此处以服务器的IP地址为IPv4地址的情况为例进行说明。
MPTCP代理接收到访问请求消息之后，根据UE的第一IP地址，使用服务器的IP地址与UE建立第一子流。结合表三所示，第一子流对应的UE端IP地址为第一IP地址，MPTCP代理端IP地址为服务器的IP地址。
第一子流建立之后，MPTCP代理与UE进一步建立第二子流。结合表三所示，第二子流对应的UE端IP地址为第二IP地址，MPTCP代理端IP地址为代理IP地址。其中代理IP地址是预先为MPTCP代理配置的IP地址，代理IP地址与第二IP地址为相同类型的IP地址，即IPv6地址。
建立第二子流可以通过两种方式，第一种方式是MPTCP代理通过第一子流向UE发送代理IP地址，UE根据代理IP地址，使用第二IP地址与MPTCP代理建立第二子流。另一种方式是UE通过第一子流向MPTCP代理发送第二IP地址，MPTCP代理根据第二IP 地址，使用代理IP地址与UE建立第二子流。对两种方式分别说明如下：
第一种方式，UE在通过第一子流发往MPTCP代理的TCP报文中设置设置MP_CAPABLE标识，向MPTCP代理查询是否能够建立第二MPTCP子流。MPTCP代理向UE返回MP_CAPABLE的ACK消息之后，再通过ADD_ADDR选项将代理IP地址发送至UE。
UE接收到代理IP地址后，使用第二IP地址向代理IP地址发送设置了MP_JOIN标识位的TCP报文，请求建立第二子流。MPTCP代理向UE返回MP_JOIN的ACK消息，第二流建立完成。
第二种方式，UE接收到MPTCP代理返回的MP_CAPABLE的ACK消息之后，UE通过ADD_ADDR选项将第二IP地址发送至MPTCP代理。
MPTCP代理接收到第二IP地址后，使用代理IP地址向第二IP地址发送设置了MP_JOIN标识位的TCP报文，请求建立第二子流。UE向MPTCP代理返回MP_JOIN的ACK消息，第二流建立完成。
204、将第一连接与第二连接建立关联。
MPTCP代理将第一连接与第二连接建立关联，该关联用于UE对服务器的访问。第一连接与第二连接建立关联之后，MPTCP代理将通过第一连接从UE接收到的报文，通过第二连接转发到服务器，将通过第二连接从服务器接收到的报文，通过第一连接转发到UE，即UE可以通过MPTCP代理访问服务器。现有技术中，如果服务器只支持IPv4地址，则UE只能通过IPv4地址访问服务器。如果服务器只支持IPv6地址，则UE只能通过IPv6地址访问服务器，本发明的实施例中，MPTCP代理与UE建立MPTCP连接，UE可以通过第一子流和第二子流同时进行数据传输，从而利用UE的双栈地址访问服务器，提高了UE与服务器之间的数据传输速率。
205、根据UE的业务数据量删除第一子流和第二子流其中之一。
步骤205为可选步骤。
UE与服务器之间的数据传输速率，同时受到第一连接与第二连接的影响，MPTCP代理可以根据UE的业务数据量对第一连接和第二连接各自包括的子流的数量进行动态调整，以调节UE与服务器之间的数据传输速率。
具体包括，在业务数据量小于第一预设阈值的情况下删除第一子流和第二子流其中之一，在业务数据量超过第二预设阈值的情况下，重新建立已经被删除的子流。其中第二预设阈值大于或者等于第一预设阈值。需要指出的是，删除两个子流其中的哪个子流与服务器支持的IP地址的类型无关。例如，服务器仅支持IPv4，代理服务器可以删除第一子流(IPv4子流)，这样，MPTCP代理与UE之间通过第二子流(IPv6子流)连接，MPTCP代理与服务器之间通过使用IPv4地址对建立的TCP或者MPTCP连接。MPTCP代理通过对UE端的IPv6数据包、服务器端的IPv4数据包进行适配和转发，第一子流删除后UE仍然可以通过MPTCP代理正常访问服务器。
类似地，当MPTCP代理与服务器建立MPTCP连接时，也可以对子流的数量进行动态调整，以使得第一连接与第二连接各自的数据传输速率相适应。
本发明的实施例所提供的数据传输方法，MPTCP代理通过接收UE发送的访问请求消息，与UE建立第二连接，与服务器建立第一连接，并将第二连接与第一连接建立关联，以完成UE与服务器之间的报文转发。其中，第二连接为MPTCP连接，包括UE使用第一IP地址与MPTCP代理建立的第一子流，以及UE使用第二IP地址与MPTCP代理建立的第二子流。UE可以利用双栈地址，通过MPTCP代理访问服务器，从而提高了UE与服务器之间的数据传输速率。
基于图2所对应的实施例，本发明的实施例还提供一种数据传输设备，用于执行上述实施例中MPTCP代理所完成的功能。参照图3所示，数据传输设备30包括：
接收单元301，用于接收UE发送的访问请求消息。其中，UE支持双栈地址，UE的IP地址包括第一IP地址和第二IP地址，第一IP地址和第二IP地址为不同类型的IP地址，访问请求消息包括服务器的IP地址以及第一IP地址，第一IP地址与服务器的IP地址为相同类型的IP地址。
