Description

一种无线通信网络中数据传输方法和装置 技术领域
本文涉及通信领域，尤其涉及一种无线通信网络中数据传输方法和装置。
背景技术
相关技术的数据通信网络中，一条数据的传输需要跨越多个传输节点，在每两个相邻传输节点间均需要建立专属于数据收发信者的传输承载，或者说传输信道。在数据传输较为频繁时，网络可以维持这条传输信道，而在数据传输不频繁时，网络会释放这条传输信道，当发送端需要发送新数据时，网络根据发送端的请求重建一条传输信道来传输新数据，可见网络为每条数据的传输所付出的控制面的开销以及对通信通道的资源占用是不可忽视的。
在目前的无线网络通信中，多为人与人的通信，通信过程所产生的数据的随机性很大。而当机器类型通信(或者称物联网)开始占据越来越大的通信市场时，机器类型的通信数据对网络的压力就变得越来越大，由于机器类通信的模式多为感应器向用户或者应用服务器上报感应数据，其数据量很小，且内容单一，在巨量机器类型终端进入无线通讯网络后，对无线通讯网络的容量和通道资源造成巨大压力，由于无线网络的通道资源受频谱资源限制，以目前最新的LTE(Long Term Evolution，长期演进)网络为例，其无线带宽最大为20MHz，远远小于有线网络吞吐量，因此这种压力在无线通信网络中表现得尤为突出。
考虑到机器类通信的数据和人与人通信不同，具有较强的规律性，因此有必要考虑针对性的数据传输优化方法，以减少小数据对无线通信网络的压力。

用户终端的类型可以是多种多样的，例如运行物联网应用的手机，或者传感器，或者任何具备物联网功能的终端。
在下述实施例中，以4种终端举例：
-终端1：智能家居中的红外移动物体感应器，功能是感应红外感应器范围内是否出现移动物体，产生的输出数据为枚举类型：0和1,0代表无移动物体，1代表有移动物体，输出数据产生周期为1秒；
-终端2：智能工业中的压力感应表，功能是感应压力数值，并向工厂 的总控后台上报感应值。上报的数据格式为2部分组成：第1部分是压力感应表的代号，该部分数据在不被用户更改的情况下是固定不变的；第2部分是压力感应表感应到的压力值，该部分数据是动态变化的，输出数据产生周期为2秒；用户在接收到数据后可监测每个代号的压力感应表的压力值的动态变化。
-终端3：便携式健康监护仪，可实时监控佩戴者的心率，将数据发送至医院健康中心后台，还可以在心率异常的情况下向医院健康中心后台发送告警指示。心率的监测有2种，一种是实时监测值，其上报周期为15秒，一种是每小时均值等级，其上报周期为1小时，其值域为[极低，低，正常，高，极高]5个等级。实时心率监测值上报的数据格式为[佩戴者代号，心率实时监控值]，每小时均值心率监测值上报的数据格式为[佩戴者代号，心率每小时均值等级]。佩戴者可以自己选择或者和医院协商选择采用哪种监测方式。
-终端4：小型合金冶炼锅炉温度传感器，分100个温区，当采用不同的合金配方和工艺时，需要对温度进行不同的曲线调节，不同工艺有不同的温度控制曲线，如果过程中某个时间的温度偏离了预定曲线，则会导致合金生产质量不达标，在本例子中，可以假设某合金的冶炼周期为1小时，温度传感器每5分钟上报一次温度监控值，要求的温度控制曲线为[50,50,60,70,80,80,80,80,80,50,25,5]，所述数字为温区值。
下面对每个终端的可优化数据进行说明。
第一种终端(红外移动物体感应器)的可优化数据有2种，分不同的场合，0和1均有较大的重复概率。例如在家庭使用时，由于屋中人的移动频度低，因此0的重复概率极大；在公共场合使用时，由于移动人数量大，因此1的重复概率较高。
第二种终端(压力感应表)的可优化数据是输出数据中的第1部分，即压力感应表的代号。
第三种终端(便携式健康监护仪)的可优化数据是佩戴者代号、心率每小时均值等级。

下面以上述几种终端为例，描述一下几种可行的实施例：
实施例1：
图2为本发明实施例1提供的无线通信网络中数据传输方法的流程示意图。方法如图2所示：
-智能家居中的红外移动物体感应器，功能是感应红外感应器范围内是否出现移动物体，产生的输出数据为枚举类型：N和Y,N代表无移动物体， Y代表有移动物体，输出数据产生周期为1秒；
步骤201：终端统计自己的发送数据，因为红外移动物体感应器的输出具有单一和较大的重复概率，因此其2种输出值可全部纳入可优化数据，均属于第一类型的可优化数据，结果如下：
Figure PCTCN2015084836-appb-000003
步骤202：终端将自己的可优化数据信息发送给基站，可优化数据信息包括：可优化数据内容、可优化数据的类型为第一类型，可优化数据对应的业务数据源的数据发送周期均为1秒，
步骤203：终端根据自己的可优化数据类型判断选择哪种优化数据发送规则，由于可优化数据种类很少，而且数据Y多在白天产生，数据N多在深夜产生，2种数据重叠概率不大，因此第一收发规则和第二收发规则均可以采用，在本例中，终端和基站约定选择优化数据发送规则2，终端将分配的临时替代码告知给基站；
临时替代码 可优化数据内容
0 N
1 Y
步骤204：基站为终端配置发送临时替代码的专用数据信道；
步骤205：终端感应，周期性向基站发送感应输出数据，输出数据用临时替代码来代替，即数据N用0代替，数据Y用1代替；
步骤206：基站收到替代码后，用该临时替代码对应的可优化数据替换掉临时替代码，即N替换掉0，Y替换掉1，这样基站就以最小的空口资源占用率成功接收到了终端发送的真实的感应数据。
实施例2：
-智能工业中的压力感应表，功能是感应压力数值，并向工厂的总控后台上报感应值。上报的数据格式为2部分组成：第1部分是压力感应表的代号，该部分数据在不被用户更改的情况下是固定不变的；第2部分是压力感应表感应到的压力值，该部分数据是动态变化的，输出数据产生周期为2秒；用户在接收到数据后可监测每个代号的压力感应表的压力值的动态变化。压力感应表的可优化数据是输出数据中的第1部分，即压力感应表的代号。
图3为本发明实施例2提供的无线通信网络中数据传输方法的流程示意图。方法如图3所示：步骤301：终端统计自己的发送数据，统计发现的可优化数据如下，属于第一类型的可优化数据；
可优化数据内容 业务数据源的数据发送周期
压力感应表的代号 2秒
步骤302：终端根据自己的可优化数据类型判断选择哪种优化数据发送规则，由于可优化数据只有1种，因此终端和基站约定选择第一收发规则；
步骤303：终端将自己的可优化数据信息发送给基站，可优化数据信息包括：可优化数据内容、可优化数据的类型为第一类型，可优化数据对应的业务数据源的数据发送周期为2秒，可优化数据在当前数据包中所处的位置为数据的起始位置；
步骤304：终端感应压力值，周期性向基站发送感应输出数据；
步骤305：终端不发送压力感应表的代号，只发送数据格式的第二部分，即感应到的压力值；
步骤306：基站收到终端发送的压力值后，默认认为终端发送了数据格式的第1部分，即压力感应表的代号。
实施例3：
-便携式健康监护仪，可实时监控佩戴者的心率，将数据发送至医院健康中心后台，还可以在心率异常的情况下向医院健康中心后台发送告警指示。心率的监测有2种，一种是实时监测值，其上报周期为15秒，一种是每 小时均值等级，其上报周期为1小时，其值域为[极低，低，正常，高，极高]5个等级。实时心率监测值上报的数据格式为[佩戴者代号，心率实时监控值]，每小时均值心率监测值上报的数据格式为[佩戴者代号，心率每小时均值等级]。佩戴者可以自己选择或者和医院协商选择采用哪种监测方式。

Figure PCTCN2015084836-appb-000004
步骤402：终端和基站约定采用哪种优化数据发送规则，由于“实时心率监测”的可优化数据种类只有1个，适合选择优化数据发送规则1；而“每小时均值心率监测”的可优化数据符合枚举类型，且种类较多有5个，适合选择第二收发规则；因此终端和基站通过专用信令约定：针对业务数据源“实时心率监测”采用第一收发规则；针对业务数据源“每小时均值心率监测”采用优化数据发送规则2；同时约定业务数据源“每小时均值心率监测”的临时替代码，例如就采用可优化数据序号作为替代码([佩戴者代号,极低]替代码为2，[佩戴者代号,低]替代码为3，以此类推)；基站为终端配置一个专用数据信道用于传输替代码，或者为终端配置一个专用上行链路控制信道用于传输替代码；
步骤403：终端将自己的可优化数据信息发送给基站，可优化数据信息包括：可优化数据内容(佩戴者代号、每小时均值心率监测的5个枚举值)、可优化数据的类型为第一类型，可优化数据对应的业务数据源的数据发送周期(实时心率监测为15秒，每小时均值心率监测为3600秒)、可优化数据在当前数据包中所处的位置为数据的起始位置(佩戴者代号位于实时心率监测数据的起始位置)；
步骤404：终端对人体进行监测，周期性向基站发送监测输出数据；
步骤405：当到达“实时心率监测”的发送周期时，终端不发送数据格式的第1部分(佩戴者代号)，只发送数据格式的第二部分，即感应到的心率值；当到达“每小时均值心率监测”的发送周期时，终端根据自己产生的数据向基站发送对应的替代码；
步骤406：基站收到终端发送的“实时心率监测”的监测值后，默认认为终端发送了“实时心率监测”数据格式的第1部分，即佩戴者代号；基站收到终端发送的“每小时均值心率监测”的替代码后，默认收到了替代码所对应的可优化数据；
步骤407：基站从可优化数据信息中提取出“佩戴者代号”，与收到的终端发送的“实时心率监测”的监测值结合组成完整的数据格式；基站将收到的“每小时均值心率监测”的替代码转换为对应的数据，形成完整的数据格式。
实施例4：
小型合金冶炼锅炉温度传感器，分100个温区，当采用不同的合金配方和工艺时，需要对温度进行不同的曲线调节，不同工艺有不同的温度控制曲线，如果过程中某个时间的温度偏离了预定曲线，则会导致合金生产质量不达标，在本例子中，可以假设某合金的冶炼周期为1小时，温度传感器每5分钟上报一次温度监控值，要求的温度控制曲线为[50,50,60,70,80,80,80,80,80,50,25,5]，所述数字为温区值。其可优化数据是温度监控值，当冶炼工艺控制稳定时，温度值呈周期数列的表现形式。
图5为本发明实施例4提供的无线通信网络中数据传输方法的流程示意 图。方法如图5所示：
步骤501：终端统计自己的发送数据，如下：
Figure PCTCN2015084836-appb-000005
可优化数据符合周期数列的数据规律，每12个数据周期循环1次，属于第二类型的可优化数据，
步骤502：终端根据自己的可优化数据类型判断选择哪种优化数据发送规则，因为属于第二类型的可优化数据，因此终端与基站约定采用第三收发规则；
步骤503：终端将自己的可优化数据信息发送给基站，可优化数据信息包括：可优化数据内容、可优化数据的类型为第二类型，可优化数据对应的业务数据源的数据发送周期为5分钟；可优化数据对应的数据规律(符合“周期数列”，下一个数据包是周期数列中的第K个)；
步骤504：终端感应温度值，周期性产生感应输出数据；
步骤505：当到达温度监控值的发送周期时，终端不发送数据；
步骤506：基站在数据发送周期到达后的预设时间段内(假设预设时间段是10秒)没有收到终端发送的任何数据，则基站认为温度感应器感应到的温度值符合标准曲线，基站根据可优化数据信息所示的数据规律推算出当前温度感应器应该产生了什么温度值。
实施例5：LTE无线通讯系统架构中基站至终端间的下行链路数据传输优化
假设与实施例1具有相同场景和网络架构(见图1)，与实施例1类似，当基站有可优化数据业务发送给终端时，可将基站作为发送端节点，终端作为接收端节点。
方案思路和实施例1相同。
-智能工业中的压力控制器来自后台的控制命令，该控制命令的数据格式为[压力控制器代号、压力目标值]，发送周期为2秒；
图6为本发明实施例5提供的无线通信网络中数据传输方法的流程示意图。方法如图6所示：
步骤601：基站统计自己的发送数据，统计发现数据的第一部分“压力控制器代号”多次重复，属于第一类型的可优化数据；
步骤602：基站根据自己的可优化数据类型判断选择哪种优化数据发送规则，由于可优化数据只有1种，因此终端和基站约定选择第一收发规则；
步骤603：基站将自己的可优化数据信息发送给终端，可优化数据信息包括：可优化数据内容、可优化数据的类型为第一类型，可优化数据对应的业务数据源的数据发送周期为2秒，可优化数据在当前数据包中所处的位置为数据的起始位置；
步骤604：基站产生压力控制指令，周期性向终端发送指令，基站不发送压力控制器代号，只发送数据格式的第二部分，即压力目标值；
步骤605：终端收到基站发送的指令后，默认认为基站发送了数据格式的第1部分，即压力控制器代号，终端从可优化数据信息中提取出压力控制器代号，补充到指令中，构成完整的指令；
实施例6：LTE无线通讯系统架构中终端至SGW间的数据传输优化
图7为本发明实施例6提供的无线通信网络中数据传输方法的流程示意图。方法如图7所示。
在LTE的系统网络架构中，终端的用户面数据和控制面数据需经过SGW，因此可以将终端与SGW一起构成数据压缩场景中的发送端节点和接收端节点。
图8为本发明实施例6提供的网络的示意图。如图8所示，终端到SGW的链路是由两条链路(终端至基站，基站至SGW)级联组成，其中，终端至基站是无线链路，基站至SGW是有线链路。
终端为便携式健康监护仪，只开启“实时心率监测”功能，每15秒产生一 次数据，病人位于医院病房，数据固定上报给医院的健康监护后台，因为通讯链路的端到端都是固定的，因此在通讯过程中，双方传输协议接口不变，双方IP地址不会变化，又因为是小数据，单次发送就可以发送完整个数据，因此无需链路层进行数据包重新分段，因此终端发送的数据包中，控制面数据是固定不变的，用户面数据则是实时变化的。
流程如下，见图7：
步骤701：终端统计自己的发送数据，统计发现的数据包格式如下，其中控制面头和控制面数据尾多次重复，属于第一类型的可优化数据
控制面数据头 实时心率监测值 控制面数据尾
步骤702：终端根据自己的可优化数据类型判断选择哪种优化数据发送规则，由于可优化数据只有1种，因此终端和SGW约定选择第一收发规则；
步骤703：终端将自己的可优化数据信息发送给SGW，可优化数据信息包括：可优化数据内容(控制面头和控制面数据尾)、可优化数据的类型为第一类型，可优化数据对应的业务数据源的数据发送周期为15秒，可优化数据在当前数据包中所处的位置为数据的起始位置和结尾位置；
步骤704：终端感应实时心率监测值，周期性向SGW发送感应输出数据；
步骤705：终端只发送数据格式的中间部分，即感应到的实时心率监测值，而不发送控制面数据；
步骤706：SGW收到终端发送的实时心率监测值后，默认认为终端发送了数据格式中的控制面部分，SGW从可优化数据信息提取出控制面数据与实时心率监测值一起构成完整的数据包；
实施例7：

或者，
