Description

一种数据传输及其控制方法及装置
本申请要求在2015年03月21日提交中国专利局、申请号为201410108473.3、发明名称为“一种数据传输及其控制方法及装置”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
本申请涉及通信技术领域，尤其涉及一种数据传输及其控制方法及装置。
背景技术
随着越来越多的家庭基站、微小区、中继等众多本地节点的部署，传统的以宏基站为主的网络架构将逐步演变为更多类型基站共存的网络架构，并提供更多层次的网络覆盖。为了改善该多类型基站共存网络架构下的相关性能，一种通过非理想链路实现多演进型基站(evolved Node B，eNB)间协作/聚合的网络架构被提出。在该架构下，用户设备(User Equipment，UE)的一部分无线承载(Radio Bearer，RB)在主eNB(Master eNB，MeNB)管理的主小区组(Master Cell Group，MCG)小区组上，这部分RB包括控制面承载——信号无线承载(Signaling Radio Bearer，SRB)和用户面承载——数据无线承载(Data Radio Bearer，DRB)，且主小区(Primary Cell，PCell)有物理上行链路控制信道(Physical Uplink Control Channel，PUCCH)信道。而同一UE的另外一部分承载在从eNB(Secondary eNB，SeNB)管理的从小区组(Secondary Cell Group，SCG)小区组上，且一个特殊小区(special cell)有PUCCH。由于该架构下UE同时在两个eNB有连接，因此被称作双连接(Dual Connectivity，DC)。当UE需要作异频测量的时候，网络需要给UE配置测量间隔，如果给一部分小区配置了测量间隔，而其他小区正常工作，那么UE在进行测量的时候，其他小区的数据也会产生中断。
下面给出相关技术的介绍。
一、双连接技术介绍
在图1所示的一种可能的多层网络覆盖环境中，MeNB与SeNB之间采用非理想的数据/信令接口——Xn接口，UE可以同时工作在MeNB和SeNB下。当连接到MeNB的UE进入SeNB所对应的小区的覆盖范围时，MeNB可以根据信号强度或负载均衡等考虑，转移UE的部分或全部的数据/信令到SeNB以获得SeNB提供的服务。从而实现UE可以同时使用MeNB和SeNB的资源，及基站间聚合(inter-eNB聚合)。在该场景下，UE的多个RB可以分别通过SCG小区和MCG小区分别承载。其中，分离到SeNB的RB可以包括DRB和/或SRB。
二、双连接架构介绍
双连接架构的架构1，如图2所示，UE在MeNB和SeNB有独立的承载，UE在每个eNB上都有独立的分组数据集中协议(Packet Data Convergence Protocol，PDCP)实体。
双连接架构的架构2，如图3所示，UE在MeNB上的连接可以有独立的承载。UE在SeNB的连接是将MeNB上的同一个演进分组系统(Evolved Packet System，EPS)承载的一部分数据分流到SeNB上传输，该EPS承载PDCP实体仍然在MeNB，而SeNB上是有独立的无线链路控制(Radio Link Control，RLC)实体。
三、测量间隔(Measurement Gap)
UE在做异频测量的时候，由于有可能会无法正常的在当前服务频点上收发数据，因此需要网络侧给UE配置测量间隔来帮助UE进行异频测量，同时又不会导致UE数据包的丢失。测量间隔的配置要服从以下测量需求。根据不同的测量图谱配置测量间隔，例如：图谱0的每个测量间隔是6毫秒，测量间隔的重复周期是40毫秒。
表1：UE支持的测量间隔配置
Figure PCTCN2015074594-appb-000001
Figure PCTCN2015074594-appb-000002
四、UE的接收机调整
当网络给UE配置了多个服务频点的时候，网络可以通过下发激活命令激活UE的服务频点。而UE在收到激活命令的时候进行接收机的调整，对于共享接收机的情况接收机调整产生的中断时间为5毫秒，对于UE有多个独立接收机的情况该调整产生的中断时间为1毫秒。由于网络知道UE调整接收机的时刻，因此可以在UE进行接收机调整的过程中不调度数据传输，从而可以防止由于UE接收机调整而产生的丢包。但是由于网络侧并不知道UE的接收机类型，因此会按照5毫秒的数据中断时间在协议规定的一段时间内不调度数据传输。
五、双连接的测量间隔配置
按UE的测量间隔配置：网络给UE下发的测量间隔配置是作用于所有的服务频点，UE在进行测量间隔内的需要中断其在所有服务频点上的数据收发。
按eNB(或小区组)的测量间隔配置：网络给UE下发的测量间隔配置是作用于部分的服务频点，例如SCG或MCG，UE在测量间隔内时候只需要中断其在这些配置了测量间隔的频点上的数据收发。
综上所述，在双连接情况下，还没有方式解决UE配置测量间隔时候产生中断的问题。如果MeNB给UE的MCG配置了一个测量间隔(measurement gap)，或SeNB给UE的SCG配置了另外一个measurement gap。这个时候当UE在一个measurement gap内进行测量的时候，UE会在开始和结束测量的时候进行接收机的频点调整，这时如果SeNB(或MeNB)无法知道MCG(或SCG)配置的measurement gap，会导致SeNB在UE进行接收机调整的时候产生丢包。此外，如果MeNB给UE配置了一个measurement gap，如果SeNB不知道该measurement gap的配置，也会产生丢包。

具体实施方式
本申请实施例提供了一种数据传输及其控制方法及装置，用以协调与同一用户设备有连接关系的多个基站间的测量间隔配置，从而避免UE在测量间隔进行测量时导致的丢包。
本申请实施例中，一个eNB设置了其要使用的测量间隔后，将该测量间隔配置发送给另外一个eNB。接收到该测量间隔配置的eNB在协议规定的时间内，在每个测量间隔的开始和结束时不对UE进行数据调度传输。如果收到该测量间隔配置的eNB也要配置一个测量间隔，则根据该接收到的测量间隔进行调整，让两个配置的测量间隔的区间完全重合或部分重合。
下面给出本申请实施例提供的技术方案的具体介绍。
实施例1：按UE的测量间隔配置。
本申请实施例提供的一种数据传输方法包括：
步骤一：MeNB给UE下发的测量间隔是作用于整个UE的，MeNB将该测量间隔配置发送给SeNB。
其中，测量间隔作用于整个UE，是指测量间隔作用于该UE所有的服务频点。
步骤二：SeNB接收到步骤一中的测量间隔配置后在整个测量间隔内不对UE进行数据的收发。
步骤三：MeNB将该测量间隔配置发送给UE，并在整个测量间隔内不对UE进行数据的收发。
步骤四：UE接收到步骤三的测量间隔后，UE在整个测量间隔内不进行数据的收发。
该测量间隔配置也可以是由SeNB配置，并发送给MeNB和UE。由于过程类似，在此不再重复描述。
实施例2：单个按小区或小区组的测量间隔配置。
本申请实施例提供的一种数据传输方法包括：
步骤一：MeNB给UE下发的测量间隔是作用于MCG小区组的，MeNB将该测量间隔配置(子帧2至子帧7)发送给SeNB。
测量间隔作用于MCG小区组，是指测量间隔作用于UE的MCG小区组的频点。
步骤二：SeNB接收到步骤一中的MCG测量间隔配置后，如图4所示进行数据停止传输处理。
例如：SeNB从该测量间隔的开始时刻(例如测量间隔的第一个子帧，即子帧2)开始的协议规定的时间内(例如连续3个子帧)不对UE进行数据的收发，以及SeNB从该测量间隔的结束时刻(例如测量间隔的最后个子帧，即子帧7)开始的协议规定的时间内(例如连续3个子帧)不对UE进行数据的收发。
再例如，SeNB从该测量间隔的第二个子帧(即子帧3)开始的协议规定的时间内(例如连续3个子帧)不对UE进行数据的收发，以及SeNB从该测量间隔的第5个子帧(即子帧6)开始的协议规定的时间内(例如连续3个子帧)不对UE进行数据的收发。
步骤三：MeNB在发送给SeNB其测量间隔配置后，将该测量间隔配置发送给UE。并在MCG的测量间隔内不在MCG的所有服务频点进行数据的收发。
步骤四：UE接收到MeNB发送的针对MCG的服务频点的测量间隔配置后，UE在MCG的测量间隔内不在MCG的所有服务频点进行数据的收发。UE保持在SCG服务频点上的数据收发，但是：
例如，UE从该测量间隔的开始时刻(例如测量间隔的第一个子帧，即子帧2)开始的协议规定的时间内(例如连续3个子帧)不进行数据的收发，以及UE从该测量间隔的结束时刻(例如测量间隔的最后个子帧，即子帧7)开始的协议规定的时间内(例如连续3个子帧)不进行数据的收发。
再例如，UE从该测量间隔的第二个子帧(即子帧3)开始的协议规定的时间内(例如连续3个子帧)不进行数据的收发，以及UE从该测量间隔的第5个子帧(即子帧6)开始的协议规定的时间内(例如连续3个子帧)不进行数据的收发。
需要说明的是，该测量间隔配置也可以由SeNB配置，并发送给MeNB和UE。且数据停发的规则可以是MeNB和UE在MCG上的数据停发规则，由于过程类似，在此不再重复描述。
该测量间隔也可以按照小区配置，则其他小区上的数据停发也遵从同样的规则，由于过程类似不再重复描述。
实施例3：多个按小区组的测量间隔配置协调全部测量间隔重合。
由于SeNB和MeNB会独立的对测量间隔进行配置，因此在这两个测量间隔配置进行协调之前，UE需要在MCG和SCG上在更多的子帧停止数据的收发，如图5所示。
本实施例中的MeNB和SeNB以及UE的数据停发规则同实施例2。
本实施例提供的数据传输方法包括：
步骤一：MeNB给UE下发的测量间隔是作用于MCG小区组的，MeNB将该MCG测量间隔配置(子帧2至子帧7)发送给SeNB。
步骤二：SeNB接收到步骤一中的MCG测量间隔配置后，如图6所示调整其SCG测量间隔的配置和MCG测量间隔的配置完全重合。SeNB对于SCG的服务频点，SeNB从该MCG测量间隔的开始时刻(例如测量间隔的第一个子帧，即子帧2)开始的协议规定的时间内(例如连续3个子帧)不对UE进行数据的收发，以及SeNB从该MCG测量间隔的结束时刻(例如测量间隔的最后个子帧，即子帧7)开始的协议规定的时间内(例如连续3个子帧)不对UE进行数据的收发，同时，在SCG的测量间隔内SeNB不对UE进行数据的收发。
SeNB将自身设置的测量间隔配置再发送给MeNB和UE。
步骤三：MeNB在发送给SeNB其MCG测量间隔配置后，将该MCG测量间隔配置发送给UE。
步骤四：MeNB接收到步骤二中的SCG测量间隔配置后，如图6所示，MeNB对于MCG的服务频点，MeNB从该SCG测量间隔的开始时刻(例如测量间隔的第一个子帧，即子帧2)开始的协议规定的时间内(例如连续3个子帧)不对UE进行数据的收发，以及MeNB从该SCG测量间隔的结束时刻(例如测量间隔的最后个子帧，即子帧7)开始的协议规定的时间内(例如连续3个子帧)不对UE进行数据的收发，同时，在MCG的测量间隔内MeNB不对UE进行数据的收发。
步骤五：UE接收到步骤三和步骤四发送的针对MCG和SCG的服务频点的测量间隔后：
UE对于SCG的服务频点，从该MCG测量间隔的开始时刻(例如测量间隔的第一个子帧，即子帧2)开始的协议规定的时间内(例如连续3个子帧)不进行数据的收发，以及从 该MCG测量间隔的结束时刻(例如测量间隔的最后个子帧，即子帧7)开始的协议规定的时间内(例如连续3个子帧)不进行数据的收发，同时，在SCG的测量间隔内不进行数据的收发。
UE对于MCG的服务频点，从该SCG测量间隔的开始时刻(例如测量间隔的第一个子帧，即子帧2)开始的协议规定的时间内(例如连续3个子帧)不进行数据的收发，以及从该SCG测量间隔的结束时刻(例如测量间隔的最后个子帧，即子帧7)开始的协议规定的时间内(例如连续3个子帧)不进行数据的收发，同时，在MCG的测量间隔内不进行数据的收发。
需要说明的是，也可以是SeNB进行测量间隔配置，并发送给MeNB和UE，并由MeNB调整其测量间隔。由于过程类似，在此不再重复描述。该测量间隔也可以按照小区配置，则其他小区上的数据停发也遵从同样的规则，由于过程类似不再重复描述。
实施例4：多个按小区组的测量间隔配置协调部分测量间隔重合。
由于SeNB和MeNB会独立的对测量间隔进行配置，因此在这两个测量间隔配置进行协调之前，UE需要在MCG和SCG上在更多的子帧停止数据的收发，如图5所示。
本实施例中的MeNB和SeNB以及UE的数据停发规则同实施例2。
本实施例提供的数据传输方法包括：
步骤一：MeNB给UE下发的测量间隔是作用于MCG小区组的，MeNB将该MCG测量间隔配置发送给SeNB。
步骤二：SeNB接收到步骤一中的MCG测量间隔配置(子帧4至子帧9)后，如图7所示调整其SCG测量间隔配置和MCG测量间隔配置部分重合，即SCG测量间隔从子帧2至子帧7。SeNB对于SCG的服务频点，SeNB从该MCG测量间隔的开始时刻(例如测量间隔的第一个子帧，即子帧4)开始的协议规定的时间内(例如连续3个子帧)不对UE进行数据的收发，以及SeNB从该MCG测量间隔的结束时刻(例如测量间隔的最后个子帧，即子帧9)开始的协议规定的时间内(例如连续3个子帧)不对UE进行数据的收发，同时在SCG的测量间隔内不对UE进行数据的收发。
SeNB将自身设置的测量间隔配置再发送给MeNB和UE。
步骤三：MeNB在发送给SeNB其MCG测量间隔配置后，将该MCG测量间隔配置发送给UE。
步骤四：MeNB接收到步骤二中的SCG测量间隔配置后，如图7所示，MeNB对于MCG的服务频点，MeNB从该SCG测量间隔的开始时刻(例如测量间隔的第一个子帧，即子帧2)开始的协议规定的时间内(例如连续3个子帧)不对UE进行数据的收发，以及MeNB从该SCG测量间隔的结束时刻(例如测量间隔的最后个子帧，即子帧7)开始的协议规定的时间内(例如连续3个子帧)不对UE进行数据的收发，同时，在MCG测量间隔内MeNB不对 UE进行数据的收发。
步骤五：UE接收到步骤三和步骤四发送的针对MCG和SCG的服务频点的测量间隔配置后：
UE对于SCG的服务频点，从该MCG测量间隔的开始时刻(例如测量间隔的第一个子帧，即子帧4)开始的协议规定的时间内(例如连续3个子帧)不进行数据的收发，以及从该MCG测量间隔的结束时刻(例如测量间隔的最后个子帧，即子帧9)开始的协议规定的时间内(例如连续3个子帧)不进行数据的收发，同时，在SCG的测量间隔内不进行数据的收发。
UE对于MCG的服务频点，从该SCG测量间隔的开始时刻(例如测量间隔的第一个子帧，即子帧2)开始的协议规定的时间内(例如连续3个子帧)不进行数据的收发，以及从该SCG测量间隔的结束时刻(例如测量间隔的最后个子帧，即子帧7)开始的协议规定的时间内(例如连续3个子帧)不进行数据的收发，同时，在MCG的测量间隔内不进行数据的收发。
需要说明的是，也可以是SeNB进行测量间隔配置，并发送给MeNB和UE，并由MeNB调整其测量间隔。由于过程类似，在此不再重复描述。该测量间隔也可以按照小区配置，则其他小区上的数据停发也遵从同样的规则，由于过程类似不再重复描述。
