Description

激活去激活的控制方法、系统、基站和计算机存储介质 技术领域
本发明涉及通信技术，具体涉及一种激活去激活的控制方法、系统、基站和计算机存储介质。
背景技术
长期演进(LTE，Long Term Evolution)系统中，根据相关技术的用户设备(UE，User Equipment)侧用户面的协议架构如图1所示。从下往上分为以下几个协议层：物理层(PHY，Physical layer)、媒体接入控制(MAC，Media Access Control)层、无线链路控制(RLC，Radio Link Control)层、分组数据汇聚协议(PDCP，Packet Data Convergence Protocol)层。其中，PHY层主要通过传输信道向MAC层或更高层传送信息；MAC层主要通过逻辑信道提供数据传输和负责无线资源分配，完成混合自动重传请求(HARQ，Hybrid Automatic Repeat Request)、调度(SCH，Scheduling)、优先级处理和复用解复用(MUX，Multiplexing)、非连续接收(DRX，Discontinuous Reception)控制UE非连续的监听和接收对应的物理信道信号和数据等功能；RLC层主要提供用户和控制数据的分段和重传服务；PDCP层主要给RRC或用户面上层完成用户数据的传递。
为向移动用户提供更高的数据速率，引入载波聚合(CA，Carrier Aggregation)技术。UE进入连接态后可以同时通过多个分量载波(如CC1，CC2)与源基站进行通信，并引入主小区(Pcell，Primary cell)和辅小区(Scell，Secondary cell)。载波聚合后续阶段，由于数据量的提升，Scell的个数会增多，如增加到4个，场景也会放宽如支持上行射频拉远头(RRH，Remote Radio Head)和中继器(repeater)，一个时间提前量(TA，Time Advanced) 不能解决问题，因此会引入多个TA。为了管理方便，使用相同的TA的服务小区归入一个TA组。这时候，包含Pcell的TA组称为主TA组(pTAG，primary TA Group)，没有包含Pcell的TA组称为附TA组(sTAG，secondary TA Group)。
这个阶段，考虑业务的突发特点，虽然UE工作在最高速率最多可能使用多至5个载波的带宽，但是在突发间隙，UE的实际业务流量很少或者接近于零，此时如果UE还继续在多个载波上等待接收数据，将会导致较高的功率开销。为了延长UE的工作时间，关闭不必要开启的无线发送接收设备，减少不必要的电池消耗，高级长期演进(LTE-A，LTE-Advanced)系统中引入了载波激活去激活的概念。UE只在激活的载波上进行数据接收，如物理下行控制信道(PDCCH，Physical Downlink Control Channel)的监听；而对于暂时不用的载波，基站通过显式命令通知或隐式规则去激活这些载波，在去激活的载波上，UE不监听PDCCH信道，也不接收物理下行共享信道(PDSCH，Physical Downlink Shared Channel)上的数据，从而达到省电的目的。其中Pcell永远不会被基站去激活，Scell可以被灵活地激活去激活。
由于网络部署的需要，多个基站可能会部署在附近，基站间的时延非常短，使得基站间的小区进行载波聚合成为可能。但是由于多个基站的小区进行载波聚合，Scell的激活去激活受Pcell归属基站(记为主基站)的控制，Scell归属基站(记为从基站)中的小区状态并不与主基站同步，这样对终端的数据调度不便。

实施例二
本发明实施例还提供了一种激活去激活的控制方法。图3为本发明实施例二的激活去激活的控制方法的流程示意图；本实施例的激活去激活的控制方法应用于第二基站中；如图3所示，所述方法包括：
步骤301：第二基站接收激活/去激活/删除/调度命令。
步骤302：所述第二基站基于所述激活/去激活/删除/调度命令确定所属辅小区的状态。
本实施例中，所述第二基站接收第一基站发送的激活/去激活/删除/调度命令；所述激活/去激活/删除/调度命令中可以仅包括激活/去激活小区的信息，还可以包括激活/去激活/删除/调度命令的发送时间；所述激活/去激活小区的信息和所述激活/去激活命令的发送时间可通过帧号和/或子帧号标识，以便于所述第二基站能够根据所述激活/去激活/删除/调度命令推断出终端已接收到激活/去激活/删除/调度命令，从而能够确定自身所属的辅小区是处于激活状态或是去激活状态。

本实施方式应用于具有自调度功能的辅小区，也即第二基站具有调度功能。在这种应用场景下，在第二基站接收到激活命令时，也即当前辅小区处于激活状态时，所述第二基站会向终端发送调度命令，由终端主动执行去激活过程。在终端接收到激活命令时，终端启动去激活定时器，在去激活定时器的时间范围内，终端激活辅小区，使辅小区处于激活状态。进一步地，在终端接收到调度命令时，重启去激活定时器，在所述激活定时器的时间范围内，辅小区依旧处于激活状态。只有在所述去激活定时器超时时，所述终端执行所述辅小区的去激活过程，使所述辅小区处于去激活状态。

采用本发明实施例的技术方案，使得第一基站和第二基站能够即时获知自身所属的辅小区的激活/去激活状态，实现了辅小区进行激活/去激活的控制，方便对终端的数据调度，提高了资源利用率和用户体验。
下面结合具体的应用场景对本发明实施例提出的激活去激活的控制方法进行详细说明。
以下应用场景中，基站1作为第一基站(P-eNB)，范围内包括一个小区，记为小区1；基站2作为第二基站(S-eNB)，范围内包括两个小区，记为小区3和小区4。其中，终端与小区1建立了连接，小区1则成为主小区。由于业务量增加，基站1根据测量报告，为终端增加了小区3，则小区3成为辅小区，小区1和小区3进行跨基站的载波聚合。基站1给终端配置了辅小区的激活去激活的配置，包含激活去激活定时器(sCellDeactivationTimer)等。
场景一
图4为本发明实施例的激活去激活的第一种示意图；结合图4所示，基站1根据测量报告确定终端业务的需求增加，决定激活小区3，发送激活小区3的命令给终端，终端在T1时刻收到小区3的激活命令，开始执行激活操作。并且，基站1发送激活小区3的命令给终端的同时(或者基站1接收到终端反馈的激活确认消息(ACK)后，通知基站2；或者，基站1在决定激活小区3并发送激活命令给终端之前通知基站2，提前的时间可以基站1控制，或者指定默认值)，基站1发送激活命令给基站2。其中，所述激活小区3的命令(和所述激活命令)，可以仅包含激活小区3的信息，还可以包含命令的发送时间，所述激活小区3的信息和所述命令的发送时间可以通过帧号和子帧号标识。基站2接收到激活命令后，根据自身接收到基站1的激活命令的时间，或者所述激活命令中包含的基站1发送激活命令的时间推断出终端在T1时刻接收到小区3的激活命令。当然，基站1还可以将终端在T1时刻接收到激活命令的信息通知基站2，基站2接收到通知消息后，无需推断即可获知终端在T1时刻接收到小区3的激活命令。
由于业务量减少，基站1决定去激活小区3，基站1发送去激活小区3 的命令给终端，终端在T2时刻接收到小区3的去激活命令，开始执行去激活操作。基站1发送去激活小区3的命令给终端的同时(或者基站1在收到终端反馈的去激活MAC CE的ACK后，通知基站2；或者，基站1在决定去激活小区3并发送去激活命令给终端之前通知基站2，提前的时间可以基站1控制，或者指定默认值)，发送去激活命令给基站2。其中，所述去激活小区3的命令(和所述去激活命令)，可以仅包含去激活小区3的信息，还可以包含命令的发送时间，所述去激活小区3的信息所述命令的发送时间可以通过帧号和子帧号标识。基站2接收到去激活命令后，根据自身接收到基站1的去激活命令的时间，或者所述去激活命令中包含的基站1发送去激活命令的时间推断出终端在T2时刻接收到小区3的去激活命令。当然，基站1还可以将终端在T2时刻接收到去激活命令的信息通知基站2，基站2接收到通知消息后，无需推断即可获知终端在T2时刻收到小区3的去激活命令。
场景二

根据测量报告，基站1确定小区3的信号质量变差，基站1决定删除小区3，发送删除小区3的命令给终端，终端在T2时刻接收到小区3的删除命令，开始执行删除操作。基站1发送删除小区3的命令给终端的同时(或者基站1在收到终端反馈的删除小区命令的响应消息后，通知基站2；或者，基站1在决定删除小区3并发送删除命令给终端之前通知基站2，提前的时间可以基站1控制，或者指定默认值)，发送删除命令给基站2。其中，所述删除小区3的命令(和所述删除命令)，可以仅包含删除小区3的信息，还可以包含命令的发送时间，所述删除小区3的信息所述命令的发送时间可以通过帧号和子帧号标识。基站2接收到删除命令后，根据自身接收到基站1的删除命令的时间，或者所述删除命令中包含的基站1发送删除命令的时间推断出终端在T2时刻接收到小区3的删除命令。当然，基站1还可以将终端在T2时刻接收到删除命令的信息通知基站2，基站2接收到通知消息后，无需推断即可获知终端在T2时刻收到小区3的删除命令。
本实施例之前，基站1还可以根据基站2提供的辅助信息，如当前无数据发送或缓冲区(buffer)为空，基站1决定是否激活或去激活基站2上的小区。即基站2通知基站1，终端在基站2上没有数据需要发送，或者数据缓冲区为空，基站1收到后，决定去激活小区3。
场景三
图6为本发明实施例的激活去激活的第三种示意图；结合图6所示，小区3是自调度的小区，即基站2能够向终端发送调度命令。基站1根据测量报告确定终端业务的需求增加，决定激活小区3，发送激活小区3的命令给终端，终端在T1时刻接收到小区3的激活命令，开始执行激活操作， 并启动去激活定时器。并且，基站1发送激活小区3的命令给终端的同时(或者基站1接收到终端反馈的激活确认消息(ACK)后，通知基站2；或者，基站1在决定激活小区3并发送激活命令给终端之前通知基站2，提前的时间可以基站1控制，或者指定默认值)，基站1发送激活命令给基站2。其中，所述激活小区3的命令(和所述激活命令)，可以仅包含激活小区3的信息，还可以包含命令的发送时间，所述激活小区3的信息和所述命令的发送时间可以通过帧号和子帧号标识。基站2接收到激活命令后，根据自身接收到基站1的激活命令的时间，或者所述激活命令中包含的基站1发送激活命令的时间推断出终端在T1时刻接收到小区3的激活命令。当然，基站1还可以将终端在T1时刻接收到激活命令的信息通知基站2，基站2接收到通知消息后，无需推断即可获知终端在T1时刻接收到小区3的激活命令。
进一步地，T2时刻，终端收到基站2发送的小区3的调度命令，重启去激活定时器。基站2在发送调度命令给终端的同时(或者基站1在收到终端反馈的调度命令的ACK后，通知基站2；或者，基站1在决定在小区3上调度终端并发送调度命令给终端之前通知基站2，提前的时间可以基站1控制，或者指定默认值)，可以向基站1发送通知消息，所述通知消息用于通知基站1在T2时刻基站2自身调度小区3给终端。所述通知消息可以仅包含调度小区3的信息，还可以包含调度命令的发送时间，所述调度小区3的信息和所述调度命令的发送时间可以通过帧号和子帧号标识。基站1接收到通知消息后，根据自身接收到基站2的通知消息的时间，或所述通知消息中包含的基站2发送调度命令的时间推断出终端在T2时刻接收到小区3的调度命令。当然，基站2还可以将终端在T2时刻接收到调度命令的信息通知基站1，基站1接收到通知消息后，无需推断即可获知终端在T2时刻接收到小区3的调度命令。
进一步地，T3时刻，终端再次接收到基站2发送的小区3的调度命令，重新启动去激活定时器。
进一步地，T4时刻，小区3的去激活定时器超时，终端开始执行小区3的去激活过程。
本实施例中，作为另一种实施方式，基站2向终端发送小区3的调度命令后，不通知基站1，仅仅在T3时刻后，即去激活定时器超时后，基站1根据去激活定时器的时间，推算出小区3处于去激活状态的时间。
本实施例中，小区3(即基站2)维护调度命令和去激活定时器，所述去激活定时器超时后基站2通知基站1，表示小区3处于去激活状态。
场景四
图7为本发明实施例的激活去激活的第四种示意图；结合图7所示，小区3是跨载波调度的小区，被小区1调度，即小区3能够被基站1的调度命令控制。基站1根据测量报告确定终端业务的需求增加时，决定激活小区3，发送激活小区3的命令给终端，终端在T1时刻接收到小区3的激活命令，开始执行激活操作，并启动去激活定时器。如图7所示。由于是基站1直接控制小区3的调度，因此基站2无需获得小区3的激活/去激活的信息。
进一步地，进一步地，T2时刻，终端收到基站1发送的小区1对小区3的调度命令，重启去激活定时器。
进一步地，T3时刻，终端再次接收到基站1发送的小区1对小区3的调度命令，重新启动去激活定时器。
进一步地，T4时刻，小区3的去激活定时器超时，终端开始执行小区3的去激活过程。
图8为本发明实施例的用户面协议架构示意图；如图8所示，本发明实施例的载波聚合中激活去激活方法中，数据无线承载在至少两个基站之 间进行分割，即数据通过至少两个基站发送；所述至少两个基站包括一个主基站(P-eNB)以及至少一个从基站(S-eNB)；其中，所述主基站包括UE载波聚合的主小区(PCell)，还可以包括UE载波聚合的至少一个辅小区(SCell)；所述从基站包括UE载波聚合的至少一个辅小区(SCell)。如图8所示，从基站(S-eNB)包括MAC层和PHY层，也即主基站和从基站均包括MAC层的所有功能，例如数据组包功能。所述主基站基于MAC层和Xn接口向所述从基站发送激活/去激活命令。所述架构是解决上述问题的架构之一，不排除采用其他协议架构，本发明实施例提供的载波聚合中激活去激活的控制方法不限定只采用上述协议架构。
