Description

一种数据传输方法和装置 技术领域
本发明实施例涉及但不限于移动通信技术，尤指一种数据传输方法及装置。
背景技术
第五代(5G)移动通信系统物联网(IoT，Internet of Things)特点是高密度、大连接，空口和基站与核心网间的S1口都将面对大量的用户数据。对于S1口来说，IoT的单一用户数据量一般较小，但是，如果大量用户并发会造成S1口识别用户的开销剧增，尤其在CP方案下即通过非接入层(NAS)消息承载用户数据而没有专门的数据承载的方式下。
目前，S1口信令使用的S1应用协议(S1AP，S1 Application Protocol)消息只承载一个特定用户的数据，使用用户终端标识(UE ID)来区分，比如：长期演进(LTE)架构中的UE S1AP ID、MME S1AP ID等。在大量用户并发的情况下，尤其是IoT场景，每个用户本身的有效数据很小，但是用于S1传输协议即底层协议的数据包控制信息开销就会占很大比例，这些海量的连接累积起来的开销所占的资源不容忽视。
发明内容
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
本发明实施例提供一种数据传输方法及装置，能够减少底层协议的控制信息开销，提升有效数据的占用率，实现资源的合理利用。
本发明实施例提供了一种数据传输方法，包括：
在预设时间内接收多个用户数据；
将接收到的多个用户数据汇聚在同一消息中发送，不同用户数据采用不同的标识进行区分。
本发明实施例还提供了一种数据传输方法，包括：从接收到的同一消息中解析出不同的用户数据，根据不同的标识识别出不同的用户数据。
本发明实施例又提供了一种数据传输装置，包括接收模块、汇聚模块；其中，
接收模块，用于在预设时间内接收多个用户数据；
汇聚模块，用于将接收到的多个用户数据汇聚在同一消息中发送；不同用户数据采用不同的标识进行区分。
本发明实施例再提供了一种数据传输装置，包括用于从接收到的同一消息中解析出不同的用户数据，根据不同的标识识别出不同的用户数据并发送。
本发明实施例还提供了一种计算机可读存储介质，存储有计算机可执行指令，所述计算机可执行指令用于执行上述数据传输方法。
通过本发明实施例的数据传输方法的汇聚处理后，有效数据和控制信息开销的比例增大，也就是说，控制信息开销占用的比例降低，这样，减少了底层协议的控制信息开销，提升了有效数据的占用率，实现了资源的合理利用。
本发明的其它特征和优点将在随后的说明书中阐述，并且，部分地从说明书中变得显而易见，或者通过实施本发明而了解。本发明的目的和其他优点可通过在说明书、权利要求书以及附图中所特别指出的结构来实现和获得。
在阅读并理解了附图和详细描述后，可以明白其他方面。
附图概述
附图用来提供对本发明技术方案的进一步理解，并且构成说明书的一部分，与本申请的实施例一起用于解释本发明的技术方案，并不构成对本发明技术方案的限制。
图1为本发明实施例数据传输方法的流程图；
图2为本发明实施例S1AP消息格式的示意图；
图3为本发明实施例实现数据传输的功能示意图；
图4为本发明实施例数据传输装置的组成结构示意图。
本发明的较佳实施方式
下面将结合附图及实施例对本发明的技术方案进行更详细的说明。
本申请发明人发现，S1AP属于上层协议，在S1口传输消息时还会增加底层协议控制头，S1AP消息承载的有效数据越少，控制头开销占用的比例就越大。如果将小包汇聚成大包后，S1AP层的有效数据变大，相应地就会减少底层协议的控制信息开销。这里仅是以S1应用协议为例进行说明，类似S1应用协议同样存在上面分析的问题，包括如5G协议等。
图1为本发明实施例数据传输方法的流程图，如图1所示，包括：
步骤100：在预设时间内接收多个用户数据。
由于IoT用户对时延不敏感，基站或核心网在处理多用户并发数据时，可以采用时间窗的方式控制数据采集时间。本步骤中的预设时间可以通过设置时间窗来实现，这样，通过时间窗控制了采集参与汇聚的用户数据的时间，进而控制了汇聚的用户数据量。
可选地，本发明实施例方法还包括：
根据实际需求设置时间窗的大小，即本发明实施例提供对时间窗的用户配置：用户数据量较大时，可以适当缩小时间窗的窗口；用户数据量较小时，可以适当放大时间窗的窗口。可选地，
根据系统的通信时延控制时间窗的上限窗口的大小；
和/或，根据数据量关键业务指标(KPI)动态调整时间窗的窗口大小。
步骤101：将接收到的多个用户数据汇聚在同一条消息中发送；不同用户数据采用不同的标识进行区分。
本步骤中的同一条消息为S1应用协议消息，或类似S1应用协议的消息，如5G消息等，本发明实施例的技术方案并不局限于S1应用协议。
本发明实施例方法可以在基站侧实现，也可以在核心网实现。特别是在多用户并发数据的情况下，对于上行数据，基站侧进行用户数据的汇聚处理，核心网对接收到的用户数据进行解析；对于下行数据，核心网进行用户数据的汇聚处理，基站侧对接收到的用户数据进行解析。
以S1应用协议为例，本步骤具体包括：
采用通用的编码方式，以及利用二级编码识别不同的用户和用户数据，将接收到的多个用户数据汇聚在同一条S1AP消息中发送。
其中，一级编码用于区分不同的用户，可以使用新增信元UE-Data List来实现；另一级编码用于区分同一用户的不同用户数据，可以使用新增信元NAS-PDU List来实现。比如：相同用户采用同一个UE ID标识，不同用户采用不同的UE ID；同一用户的多个用户数据之间采用不同的协议数据单元(PDU)ID。
以LTE S1AP协议为例，现有的上行非接入层传输(Uplink NAS Transport)信元格式、下行非接入层传输(Downlink NAS Transport)信元格式如表1所示：
Figure PCTCN2017100569-appb-000001
表1
从表1可见，现有的S1AP消息只能承载1个用户的用户数据(NAS-PDU)。表1中，M表示强制的，该项的取值还可以是可选择的(Optional)即O、有条件的(Conditional)即C。
本发明实施例优化后的上行非接入层传输(Uplink NAS Transport)信元格式、下行非接入层传输(Downlink NAS Transport)信元格式如表2所示：
Figure PCTCN2017100569-appb-000002
表2
如表2所示，新增信元UE-Data List可以用于设置N个不同用户的标识；新增信元NAS-PDU List可以用于设置N个同一用户下的多个用户数据的标识。通过优化后表2所示的S1AP消息可见，优化后的S1AP消息可以承载多个用户的数据(NAS-PDU)。
本实施例还包括：
接收到来自外部的S1AP消息，从来自外部的S1AP消息中解析出不同 的用户数据，根据不同的标识识别出不同的用户数据。
具体地，根据UE ID识别出不同用户的用户数据，根据PDU ID识别出同一用户的多个不同用户数据；
具体地，当本发明实施例装置设置在基站侧时，通过空口将识别出的用户数据发送给对应的用户；当本发明实施例装置设置在核心网时，将识别出的用户数据发送给核心网相应节点。
图2为本发明实施例中S1AP消息格式的示意图，如图2上图所示，是汇聚前S1AP消息的结构，如图2下图所示，是汇聚处理后的S1AP消息，经过本发明实施例的数据传输方法的汇聚处理后，有效数据和控制信息开销的比例增大，也就是说，控制信息开销占用的比例降低，这样，减少了底层协议的控制信息开销，提升了有效数据的占用率，实现了资源的合理利用。
图3为本发明实施例实现数据传输的功能示意图，如图3所示，在S1接口的上层如S1AP层，将多个单一用户的小包数据如NAS PDU，汇聚成大包数据，实现大管道数据传输。上行在基站侧完成汇聚，核心网则进行解析；下行在核心网完成汇聚，基站侧进行解析。汇聚时通过S1AP编码整合用户数据的信息，在解析时解码分离，采用不同的标识区分不同的用户以及同一用户的不同用户数据。
下面结合图3对本发明的实施例进行详细描述。
比如：结合图3所示，以下行数据传输为例，假设用户1在一段时间内依次发送上行数据块(NAS PDU)1、上行数据块4、上行数据块5，基站在一段时间内先后接收到携带上述数据块的三条上行NAS消息；基站侧根据预先设定的时间窗，进行用户数据接收，假设在时间窗内收到用户1的用户数据1、用户数据4、用户数据5，对接收到的用户数据进行汇聚处理，将用户数据1、用户数据4、用户数据5整合并编码到同一条S1AP消息中，并采用不同的PDU ID区分用户1的用户数据1、用户数据4和用户数据5，采同一个UE ID对来自用户1的用户数据进行标识，最后发送该S1AP消息。相应地，
在核心网，对接收到的S1AP消息进行用户数据解析，将用户数据1、用户数据4、用户数据5从S1AP消息中解码提取出来，并根据UE ID确定 出接收到的用户数据都是用户1的用户数据，并根据PDU ID区分用户数据1、用户数据4和用户数据5，之后发送给核心网相应节点即可。
再如：结合图3所示，以下行数据传输为例，假设用户1、用户2和用户3分别发送上下行数据块(NAS PDU)1、下行数据块2、下行数据块3，核心网在一段时间内先后接收到携带上述数据块的三条下行NAS消息；网络侧根据预先设定的时间窗，进行用户数据接收，假设在时间窗内收到用户数据1、用户数据2和用户数据3，对接收到的用户数据进行汇聚处理，将用户数据1、用户数据2和用户数据3整合并编码到同一条S1AP消息中，并采用不同的UE ID标识区分不同的用户，最后发送该S1AP消息。相应地，
基站对接收到的S1AP消息进行用户数据解析，将用户数据1、用户数据2、用户数据3从S1AP消息中解码提取出来，并根据UE ID识别出用户数据1是用户1的用户数据，用户数据2是用户2的用户数据，用户数据3是用户3的用户数据，之后分别将用户数据1、用户数据2、用户数据3分别发送给用户1、用户2、用户3。
又如：结合图3所示，以下行数据传输为例，假设用户1、用户2和用户3分别发送上行数据块(NAS PDU)1、上行数据块2、上行数据块3、上行数据块4、上行数据块5，基站在一段时间内先后接收到携带上述数据块的5条上行NAS消息；基站侧根据预先设定的时间窗，进行用户数据接收，在时间窗内收到用户数据1、用户数据2、用户数据3、用户数据4、用户数据5，对接收到的用户数据进行汇聚处理，将用户数据1、用户数据2、用户数据3、用户数据4、用户数据5整合并编码到同一条S1AP消息中，并采用不同的PDU ID区分用户1的用户数据1、用户数据4和用户数据5，采同一个UE ID对来自用户1的用户数据进行标识，最后发送该S1AP消息。相应地，
在核心网，对接收到的S1AP消息进行用户数据解析，将用户数据1、用户数据2、用户数据3、用户数据4、用户数据5从S1AP消息中解码提取出来，并根据PDU ID区分用户1的用户数据1、用户数据4和用户数据5，根据UE ID识别出用户数据1、用户数据4和用户数据5是用户1的用户数据，用户数据2是用户2的用户数据，用户数据3是用户3的用户数据，之后发送给核心网相应节点即可。
