Description

一种数据传输方法及终端 技术领域
本发明涉及数据处理领域，尤其涉及一种数据传输方法及终端。
背景技术
随着移动互联网技术的发展，尤其是智能化的终端如手机、平板电脑等的兴起和普及，越来越多的用户直接使用这些终端进行网络访问，而且，随着终端操作系统及硬件性能的快速发展，使得许多原来在电脑上使用的软件可在智能化、小型化、可移动的终端上使用，尤其社交软件的使用频率较高，这些软件一般属于即时消息类软件，与网络的连接具有突发性，定时性等特点。以某一即时消息类软件为例，该软件在终端的操作系统上每两分钟发一个心跳包，用以定时通知服务器当前的状态。网络控制器需要为此传输数十条网络信令如接入信令、承载建立信令等，而传输完成后，网络控制器7-15秒后释放空口资源。在一个月中，使用该即时消息类软件的用户即使不进行任何操作，也会发送22 320个心跳包，相当于消耗了发送22 320条短信的信令处理能力或相当于拨打1万多个电话的信令处理能力，但是却仅产生1.83兆字节的流量。
由此可见，终端在使用即时消息类软件时，为了维持和服务器的连接，会产生了大量的网络信令，而且所产生的网络信令仅仅为了进行很少字节的传输。这种信令可能会对网络的正常业务产生干扰。同时，考虑到未来网络的发展前景，到时将会有大量的终端连接在网络上，与发送即时消息类似的，很多终端将会间断性的向网络发送内容较少、长度较短的数据，其发送的频度可能很小，但是由于终端数量的越来越多，因而也会造成对网络信令资源的大量消耗。

附图说明
为了更清楚的说明本发明实施例或现有技术中的技术方案，下面将对实施例中所需要使用的附图作简单的介绍，显而易见的，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为本发明第一实施例终端结构示意图；
图2为本发明第二实施例终端结构示意图；
图3为本发明第三实施例终端结构示意图；
图4为本发明第一实施例数据传输方法流程示意图；
图5为本发明第二实施例数据传输方法流程示意图。
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、完整的描述，显然，所描述的实施例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作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。
请参见图1，为本发明第一实施例终端结构示意图，本发明实施例终端1接收基站分配的专用通道资源(包括时域资源、链路资源等)，与基站建立专用通道的连接，本发明实施例终端1包括：检测单元10和第一选择单元20，其中，
检测单元10，用于检测第一通道的逻辑信道是否包括第一待传输数据，第二通道的逻辑信道是否包括第二待传输数据。
具体的，本发明实施例的第二待传输数据包括：非连续传输且长度小于预设阈值的应用数据，其中，非连续传输且长度小于预设预设阈值的应用数据包括非连续传输且长度小于预设阈值的应用信令和/或非连续传输且长度小于预设阈值的分组，第一待传输数据包括：连续传输的大量数据。
需要知道的是，第二通道是一个网络范畴的概念，不仅仅局限于空中接口，还包括网络侧，是一个端到端的概念，即第二通道包含空口的无线通道和网络的传输通道。同时，第二通道可以是每个基站一个，也可以是多个，当存在多个第二通道时，可以是按应用分类的，可以一个应用一个，也可以是多个应用共享一个。从空口物理资源的分配来看，同一个通道的资源可以是连续的，也可以是离散的，分布在不同的时频资源块上。第二通道仅传输空闲态的用户数据，首先要判定是否该用第二通道进行传输。由于终端处于空闲态时，有可能需要发送连续传输的大量数据(第一待传输数据)，也有可能只是需要发送非连续传输且长度小于预设阈值的应用数据(第二待传输数据)，当有第一待传输数据要进行传输时，应该采用第一通道来进行传输，而如果有第二待传输数据要进行传输时，则可以采用第二通道进行传输。
当然，若第一通道的逻辑信道包括第一待传输数据，选择第一通道传输第一待传输数据。
应当理解，本发明实施例终端用于接收基站分配的专用通道资源(包括时域资源、链路资源等)，并与基站建立第二通道的连接。
第一选择单元20，用于若检测到第一通道的逻辑信道不包括第一待传输数据，且第二待传输数据的长度小于第二通道传输数据的预设阈值，则选择第二通道传输第二待传输数据。
具体的，第一通道的逻辑信道不包括第一待传输数据即终端1处于空闲状态(idle态)。
若第二通道为一个，且第二待传输数据的长度小于第二通道传输数据预设阈值，则选择第二通道传输所述第二待传输数据。
若第二通道为至少两个，且各个所述第二通道的第二待传输数据的总长度均小于第二通道传输数据的预设阈值时，则选择第二通道传输所述第二待传输数据。应当理解，至少两个第二通道的逻辑信道的第二待传输数据可映射到同一个第二通道的传输信道进行传输，其中，预设的阈值可以是协议定义，也可以是针对每一个第二通道定义的变化的值，即各个第二通道预设的阈值可以不同。
需要知道的是，若第二通道为至少两个，且各个第二通道的第二待传输数据的总长度大于或者等于第二通道传输数据预设阈值时，则选择第一通道传输第二待传输数据，第二待传输数据可映射到第一通道进行传输。
应当理解，选择第二通道传输第二待传输数据之后，还包括：接收基站反馈的传输结果，通过第二通道传输反馈的传输结果。在本发明实施例的其它实施方式中，如果用户收到NACK的反馈，则系统进行自动重传一定的次数N，比如，N为4。当然，系统也可以不进行任何反馈，而是由应用层自动进行重传，这依赖于系统设计，如果由应用层进行重传，就不需要由底层进行反馈和重传。
本发明实施例的终端，可选择专用通道传输非连续传输且长度小于预设阈值的应用数据，该方法可节约网络资源，有效提高数据传输的效率。
请参见图2，为本发明第二实施例终端结构示意图，图2所示的终端2是由图1所示终端1进行优化得到的，图2所示的装置中除了包括图1所示的终端包括的单元之外，第一选择单元20包括：第一选择模块21、第二选择模块 22，第三选择模块23，终端2还包括:第二选择单元30、反馈单元40，其中，
第一选择模块21，用于若第二通道为一个，且第二待传输数据的长度小于第二通道传输数据预设阈值，则选择第二通道传输第二待传输数据。
第二选择模块22，用于若第二通道为至少两个，且各个第二通道的第二待传输数据的总长度均小于第二通道传输数据的预设阈值时，则选择第二通道传输所述第二待传输数据。
第二选择单元30，用于若第一通道的逻辑信道包括第一待传输数据，选择第一通道传输第一待传输数据。
具体的，至少两个第二通道的逻辑信道的第二待传输数据可映射到同一个第二通道的传输信道进行传输。其中，预设的阈值可以是协议定义，也可以是针对每一个第二通道定义的变化的值，即各个第二通道预设的阈值可以不同。
需要知道的是，若第二通道为至少两个，且各个第二通道的第二待传输数据的总长度大于或者等于第二通道传输数据预设阈值时，则选择第一通道传输第二待传输数据，第二待传输数据可映射到第一通道进行传输。
每个第二通道逻辑信道的数据如果通过第二通道进行传输，那么从逻辑信道到物理信道的过程都是独立的，每个逻辑通道到传输通道的映射以及传输通道到物理通道的映射都是独立的。如果第二通道的逻辑信道数据通过第一通道进行传输，则通过传输信道的共享信道及物理共享信道进行传输，此时数据传输方式同传统数据传输方式一样，是复用的传输方式。
当终端确定采用第二通道进行传输后，其传输方式可采用竞争的方式，包括：载波侦听/冲突检测、码分复用等方式，这些方式均可通过协议定义。
当小区中的用户共享第二通道时，需要确定如何划分资源以及终端如何从第二通道资源中选择其中一块进行传输。例如，在LTE系统中，对一个正常循环前缀(CP)的一个PRB，包含12个子载波和7个符号，系统为第二通道分配资源时，可以分配多个物理资源块，本发明实施例可分配4个PRB，对每个第二通道，如果需要用2个PRB，则可以分为两组。假定PRB 1和PRB 2可以用于一个用户传输，而PRB 3和PRB 4则可以用于另一个用户传输，PRB1和PRB 2组成的资源块为URB(中文名称：用户资源块)。在实际系统中，可以同时为第二通道分配多个URB。那么，当用户选择上行传输资源时，需 要随机或依据一定预设规则从多个URB中选择一个资源块进行传输。其选择规则可以多种多样，但是选择规则要尽量保证各个终端的选择结果是均匀分布，尽量不要引起冲突。当然，这里的选择不仅包括在单个子帧(或者连续子帧)的分配，也包括时域的分配，因为第二通道资源在时域上是周期性调度的。
反馈单元40，用于接收基站反馈的传输结果，通过第二通道传输反馈的传输结果。
具体的，选择第二通道传输第二待传输数据之后，还包括：接收基站反馈的传输结果，通过第二通道传输反馈的传输结果。在本发明实施例的其它实施方式中，如果基站反馈传输结果，则需要在下行第二通道的资源上进行反馈。如果系统采用类似于WiFi的竞争方式，则不需要专门的反馈资源，此时基站可以选择一个资源块进行反馈传输，在进行反馈传输时，需要包含能够识别终端的标识。如果是频分双工的方式，则选择一个下行资源块进行传输，终端需要在一定时间内持续监控下行资源块以获取反馈信息，多个用户的反馈信息可以在同一个URB里进行传输，如果用户收到NACK的反馈，则系统进行自动重传一定的次数N，比如N为4次。当然，系统也可以不进行任何反馈，而是由应用层自动进行重传，这依赖于系统设计，如果由应用层进行重传，就不需要由底层进行反馈和重传。
本发明实施例的终端，可选择专用通道传输非连续传输且长度小于预设阈值的应用数据，该方法可节约网络资源，有效提高数据传输的效率。

检测第一通道的逻辑信道是否包括第一待传输数据，第二通道的逻辑信道是否包括第二待传输数据。
若检测到第一通道的逻辑信道不包括第一待传输数据，且第二待传输数据的长度小于第二通道传输数据的预设阈值，则选择第二通道传输第二待传输数据，第二待传输数据包括：非连续传输且长度小于预设阈值的应用数据。非连续传输且长度小于预设阈值的应用数据包括非连续传输且长度小于预设预设阈值的应用信令和/或非连续传输且长度小于预设阈值的分组。
在可选实施例中，处理器301调用存储器304中存储的程序代码还可以执行以下操作：
