Description

一种业务数据传输方法及设备
本申请要求在2014年12月02日提交中国专利局、申请号为201410724667.6、发明名称为“一种业务数据传输方法及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及无线通信技术领域，特别涉及一种业务数据传输方法及设备。
背景技术
现有技术中，频谱可以分为授权频谱和非授权频谱。其中，授权频谱为划分好的专用频谱，其干扰基本可预知，而非授权频谱上没有规划具体的应用系统，可以为多种系统共享，如LTE(Long Term Evolution，长期演进)、WiFi(无线网络)等，因此，其干扰不可预知，其数据传输的传输性能和服务品质存在很大不确定性，当非授权频谱的干扰较小时，传输性能和服务品质可以被接受，当非授权频谱的干扰较大时，则会降低数据传输性能，导致服务品质下降。
随着移动数据业务量的不断增长，LTE系统开始考虑在非授权频谱资源上部署传输，以提高用户体验。但是，由于非授权频谱资源可以由多种系统共享，因此LTE系统在非授权频谱资源上的干扰情况较不稳定。
目前，一种通过载波聚合方式实现UE(User Equipment，用户终端)在LTE-U(LTE-unlicensed，LTE非授权频段的载波)载波小区上进行传输的方法为：将LTE-U频段上的小区作为CA(Carrier Aggregation，载波聚合)下的SCell(Secondary Cell，辅小区)使用；针对LTE-U频段上的干扰动态不稳定的情况，网络通过SCell激活去激活机制，或者SCell on/off机制停止在该小区上为该UE提供业务传输服务。当SCell off或去激活时候，UE侧会清空该SCell上对应的HARQ(Hybrid Automatic Repeat Request，混合自动重传请求)缓存数据，停止所有上下行数据或信号的传输。
现有技术中，由于LTE-U SCell的激活去激活频率较高，会导致其上的MAC(Medium Access Control，媒体接入控制)HARQ数据清空的概率提高，从而降低了业务数据传输的成功率。即使RLC(Radio Link Control，无线链路控制)ARQ(Automatic Repeat Request，自动重传请求)机制可以保证业务传输的有效性，但当在LTE-U小区中的HARQ数据经常被清空的情况下，也会延长RLC层的传输时延，加大RLC层出现不可恢复错误的发生，从而导致用户的连接需要重新建立的发生。
综上所述，现有技术中，通过载波聚合方式实现UE在LTE-U载波小区上进行传输的方法，数据传输的成功率不高，降低了用户体验。

针对上行数据的数据传输方法：
在UE作为发送设备实现对上行数据的传输过程中，可以采用如下方式进 行判断第一小区是否能够满足业务数据的传输要求：
方式一：
实施中，发送设备可以根据下列方式判断第一小区是否能够满足业务数据的传输要求：
所述发送设备在通过所述第一小区发送业务数据时，若针对业务数据的AM(Acknowledged Mode，应答模式)RLC重传次数达到设定的第一门限值，则确定所述第一小区不能够满足所述业务数据的传输要求。
例如：将UE的AM RLC重传次数的门限值设定为3次，该UE通过非授权频谱上的一个小区发送一业务数据时，第一次发送失败，UE对该业务数据进行重传操作，当重传次数达到3次时，UE确定该小区不能够满足该业务数据的传输要求。
实施中，发送设备在确定第一小区不满足业务数据的传输要求后，选择其他的小区进行业务数据的发送，具体的实现方式可以为：
实施中，所述发送设备在确定所述第一小区无法满足业务数据的传输要求后，确定第二小区，包括：

在本发明实施例中，高可靠性小区为干扰变化相对慢的小区，比如PCell(Primary Cell，主小区)、后向兼容的小区(即传统终端可以驻留的小区)。
例如：UE确定当前发送业务数据的非授权频谱上的一个小区不能满足该 业务数据的传输要求后，UE确定在PCell上发送本次传输的RLC PDU。
又例如：UE确定当前发送业务数据的非授权频谱上的一个小区不能满足该业务数据的传输要求后，UE确定在后向兼容的小区上发送AM RLC对应的后续数据。
又例如：UE确定当前发送业务数据的非授权频谱上的一个小区不能满足该业务数据的传输要求后，UE确定在PCell上发送后续所有的UE业务数据。

实施中，发送设备上报的BSR信息中除了包括需要在高可靠性小区传输的数据量以外，还可以包括当前的不挑选服务小区传输的数据量。
实施中，针对需要在高可靠性小区传输的数据进行特殊的LCP(Link Control Protocol，链路控制协议)选择过程，具体的LCP选择过程为：
实施中，所述发送设备在确定所述第一小区无法满足业务数据的传输要求后，确定第二小区之后，还包括：

方式二：
实施中，发送设备可以根据下列方式判断所述第一小区是否能够满足业务数据的传输要求：
所述发送设备在通过所述第一小区发送业务数据时，若BLER超过设定的第二门限值，则确定所述第一小区不能够满足所述业务数据的传输要求。
例如：UE将BLER设定为10％，并且在上行数据发送过程中，将HARQ 发送失败的数据块作为一个错块。UE通过非授权频谱上的一个小区发送具有100个数据块的业务数据，在发送过程中，当HARQ发送失败的数据块达到10块时，UE确定该小区不能够满足该业务数据的传输要求。
实施中，所述BLER为Per UE的BLER或Per CC的BLER。
具体的，发送设备在确定第一小区不满足业务数据的传输要求后，选择其他的小区进行业务数据的发送，具体的实现方式为：
实施中，所述BLER为Per UE的BLER；
所述发送设备在确定所述第一小区无法满足业务数据的传输要求后，确定第二小区，包括：
所述发送设备在确定所述第一小区无法满足业务数据的传输要求后，确定高可靠性小区。
例如：UE根据Per UE的BLER，确定当前发送业务数据的非授权频谱上的一个小区不能满足该业务数据的传输要求后，UE确定在PCell上发送该业务数据。

实施中，发送设备在确定BLER(Per UE的BLER或Per CC的BLER)超过设定的第二门限值后，可以通知网络侧设备，具体的通知方式为：
实施中，所述发送设备在确定BLER超过设定的第二门限值之后，还包括：
所述发送设备通知网络侧设备BLER超过设定的第二门限值，以使网络侧设备去激活或去配置所述第一小区。
例如：当UE侧的Per UE的BLER到达10％时，UE停止在质量不好的小区(例如：RSRP(Reference signal received power，参考信号接收功率)低RSRQ(Reference Signal Time Difference，参考信号时间差)高的小区)上发送数据，并通知网络侧设备BLER超过门限值，网络侧设备在接收到通知后， 去激活质量不好的小区。
又例如：当UE侧的Per UE的BLER到达10％时，UE停止在LTE-U小区上发送数据，并通知网络侧设备BLER超过门限值，网络侧设备在接收到通知后，去激活LTE-U小区。
又例如：当UE侧的Per UE的BLER到达8％时，通知网络侧设备BLER超过门限值，网络侧设备在接收到通知后，停止UE在质量不好的小区(例如：RSRP低RSRQ高的小区)上发送数据，并去配置质量不好的小区。
又例如：当UE侧的Per UE的BLER到达8％时，通知网络侧设备BLER超过门限值，网络侧设备在接收到通知后，停止UE在LTE-U小区上发送数据，并去激活LTE-U小区。
又例如：当UE侧的Per CC的BLER到达10％时，UE停止在该质量不好的小区(例如：RSRP低RSRQ高的小区)上发送数据，并通知网络侧设备BLER超过门限值，网络侧设备在接收到通知后，去激活该质量不好的小区。

又例如：当UE侧的Per CC的BLER到达8％时，通知网络侧设备BLER超过门限值，网络侧设备在接收到通知后，停止UE在该质量不好的小区(例如：RSRP低RSRQ高的小区)上发送数据，并去配置该质量不好的小区。
又例如：当UE侧的Per CC的BLER到达8％时，并通知网络侧设备BLER超过门限值，网络侧设备在接收到通知后，停止UE在该LTE-U小区上发送数据，并去激活该LTE-U小区。
实施中，所述高可靠性小区是主小区PCell或后向兼容的小区。
针对下行数据的数据传输方法：
网络侧设备作为发送设备实现对下行数据的传输过程中，可以采用如下方式进行判断第一小区是否能够满足业务数据的传输要求：

实施中，发送设备根据下列方式判断所述第一小区是否能够满足业务数据的传输要求：
所述发送设备在通过所述第一小区发送业务数据时，若针对业务数据的AM RLC重传次数达到设定的第一门限值，则确定所述第一小区不能够满足所述业务数据的传输要求。

所述发送设备在确定BLER超过设定的第二门限值之后，还包括：
所述发送设备去激活或去配置所述第一小区。
例如：当网络侧设备侧的Per UE的BLER到达10％时，停止在质量不好的小区(例如：RSRP低RSRQ高的小区)上发送数据，并去激活质量不好的小区。
又例如：当网络侧设备侧的Per UE的BLER到达10％时，停止在LTE-U小区上发送数据，并去激活LTE-U小区。
