Description

应用于超级小区的通信方法和装置
本申请要求于2016年03月03日提交中国专利局、申请号为201610122160.2、发明名称为“应用于超级小区的通信方法和装置”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
本申请涉及通信领域，并且更为具体地，涉及一种应用于超级小区的通信方法和装置。
背景技术
现有技术中，为了保证用户设备(User Equipment，UE)业务的连续性，需要对UE进行移动性管理。例如，UE从源小区的覆盖范围移动到目标小区的覆盖范围时，需要及时地完成小区之间的切换。
但是，在现有的通信系统中，移动性管理的设计思想均是以网络为中心的设计思想(UE follows network)。以处于激活态的UE为例，为了实现该UE的移动性管理，网络中的各小区会发送下行参考信号，供该UE测量。UE会以测量报告的形式将测量结果上报至网络侧，网络基于该UE的测量报告进行切换判决，将UE切换至信号条件好的小区进行数据传输。
但是，在移动通信系统的后续演进过程中，为了满足巨量的数据通信需求，可能会在是热点区域集中部署大量的小小区(small cell)，如果继续采用以网络为中心的设计思想，会引起UE的移动性管理难的问题。例如，在热点区域，UE需要测量大量的small cell，对于UE的测量能力要求较高；又如，UE进行测量并上报测量报告后才能进行切换，由于small cell的覆盖范围小，UE可能很快移出small cell的覆盖范围，可能造成切换不够及时而导致切换失败，比如测量报告发送到small cell失败，切换命令发送失败等。再如，由于超密集的小区部署，测量报告上报以及切换等操作可能产生大量的空口信令，大量消耗空口资源和网络的处理资源。
发明内容
本申请提出一种应用于超级小区的通信方法、无线接入网控制器、用户设备和传输点，以解决热点区域的移动性管理难的问题。
第一方面，提供一种应用于超级小区的通信方法。所述方法包括：无线接入网的控制器为第一超级小区中的UE分配第一传输点(Transmission Point，TP)集和第二TP集合。所述第一超级小区包括多个TP，所述第一TP集合和所述第二TP集合各自均包括所述多个TP中的至少一个TP，所述第一TP集合中的TP用于测量所述UE发送的上行参考信号，所述第二TP集合中的TP用于与所述UE进行数据通信；所述无线接入网的控制器向所述UE发送所述UE的第一专用用户设备标识(Dedicated User Equipment Identity，DUI)，所述第一DUI用于在所述第一超级小区中标识所述UE；所述无线接入网的控制器接收所述第一TP集合中的TP发送的测量报告，所述测量报告携带所述UE发送的上行参考信号的信号强度信息；所述无线接入网的控制器根据所述第一TP集合中的TP的 测量报告，更新所述第二TP集合。可选地，无线接入网的控制器可以向第一TP集合中的TP和/或第二TP集合中的TP发送第一DUI。可选地，第一TP集合中的TP可以基于第一DUI测量UE发送的上行参考信号。可选地，第二TP集合中的TP可以基于第一DUI与UE进行数据通信。可选地，测量报告可用于指示UE发送的上行参考信号的强度或质量。
现有技术是小区(或称网络侧)发送下行参考信号，UE对小区的下行参考信号进行测量，并上报测量报告，再由网络侧基于UE的测量报告进行小区切换判决，从而实现UE的移动性管理。而在本申请的方案中，无线接入网的控制器为UE分配第一TP集合和第二TP集合，其中，第二TP集合可用于传输UE的数据，第一TP集合可用于测量UE发送的上行参考信号，无线接入网的控制器基于第一TP集合中的TP的测量报告更新第二TP集合。也就是说，在本申请的方案中，参考信号的发送方变成了UE，参考信号的测量者变成了超级小区中的TP，随着UE的移动，网络侧不断更新用于传输UE数据的第二TP集合，但从UE的角度来看，UE并没有明显感知网络的变化，无需复杂的测量和上报操作，降低了UE的复杂度，而且整个过程无需UE与TP之间过多的空口信令交互，节省了空口资源，从而解决了热点区域的移动性管理难的问题。
结合第一方面，在第一方面的第一种实现方式中，在所述无线接入网的控制器为第一超级小区中的UE分配第一TP集合和第二TP集合之前，所述方法还包括：所述无线接入网的控制器确定所述UE的工作模式为非小区模式，其中，所述UE支持的工作模式包括小区模式和非小区模式，所述小区模式是基于UE对下行参考信号的测量进行移动性管理的工作模式，所述非小区模式是通过测量UE发送的上行参考信号进行移动性管理的工作模式。可替换地，所述小区模式是网络侧基于UE对网络侧发送的下行参考信号进行测量得到的测量结果进行移动性管理的工作模式，所述非小区模式是网络侧基于测量UE发送的上行参考信号得到的测量结果进行移动性管理的工作模式。
通过为UE设置小区模式和非小区模式在内的多种工作模式，能够更好地兼容现有技术(即兼容小区模式)。
结合第一方面的第一种实现方式，在第一方面的第二种实现方式中，所述无线接入网的控制器确定所述UE的工作模式为非小区模式，包括：在所述UE通过所述第一超级小区内的TP发起随机接入过程之后，所述无线接入网的控制器接收所述第一超级小区内的TP发送的请求信息，所述请求信息用于请求所述无线接入网的控制器确定所述UE的工作模式，所述请求信息包括所述UE的如下参数的至少一种：所述UE的类型、所述UE的移动速度、所述UE的位置、所述UE的业务、所述UE支持的工作模式以及所述UE的能力；所述无线接入网的控制器根据所述请求信息中携带的UE的参数，确定所述UE的工作模式为非小区工作模式；所述方法还包括：所述无线接入网的控制器向所述UE、以及所述第二TP集合中的TP发送用于指示所述UE的工作模式为非小区模式的信息。例如，请求信息中携带UE支持非小区模式，则无线接入网的控制器确定UE的工作模式为非小区模式；又如，请求信息中携带UE的位置，无线接入网的控制器根据UE的位置，确定UE是否位于热点区域；当UE位于热点区域时，确定UE的工作模式为非小区模式。
结合第一方面的第一至第二种实现方式的任一种，在第一方面的第三种实现方式中，所述方法还包括：所述无线接入网的控制器根据所述第一TP集合中的TP的测量报告， 确定将所述UE的工作模式切换至小区模式；所述无线接入网的控制器向所述UE发送模式切换消息，所述模式切换消息用于指示所述UE从所述非小区模式切换至所述小区模式，所述模式切换消息包含所述UE在所述小区模式下的服务小区的小区标识。具体地，所述无线接入网的控制器根据所述第一TP集合中的TP的测量报告，确定将所述UE的工作模式切换至小区模式可以包括：所述无线接入网的控制器检测到发送测量报告的TP位于超级小区的边缘，即UE即将离开超级小区，此时，无线接入网的控制器可以将UE切换至小区模式。

在某些实现方式中，网络侧可指接入网网络侧，可以包括TP和无线接入网的控制器等。
在某些实现方式中，所述第一超级小区包括多个小区。
在某些实现方式中，所述第二TP集合为所述第一TP集合的子集。
在某些实现方式中，所述第一DUI用于所述第一TP集合中的TP接收所述UE发送的上行参考信号，和/或所述第一DUI用于所述第二TP集合中的TP与所述UE进行数据通信。
将第二TP集合设置为第一TP集合的子集，第二TP集合会随着第一TP集合的动态更新而动态更新，简化了网络侧对多个TP集合的更新与维护方式。
在某些实现方式中，第一TP集合的更新可指第一TP集合的成员的更新；或者，第一TP集合的更新可指以下中的至少一种：删除第一TP集合中的TP，向第一TP集合添加TP。同理，第二TP集合的更新可指第二TP集合的成员的更新；或者，第二TP集合的更新可指以下中的至少一种：删除第二TP集合中的TP，向第二TP集合添加TP。
在某些实现方式中，第一DUI用于在第一超级小区中标识UE可指第一DUI用于第一超级小区中的TP识别所述UE。例如，第一超级小区中，UE的上下行数据及上行参考信号均可通过该第一DUI加扰。第二DUI用于在第二超级小区中标识UE可指第二DUI用于第二超级小区中的TP识别所述UE。例如，第二超级小区中，UE的上下行数据及上行参考信号均可通过该第二DUI加扰。此外，第一DUI可以在第一超级小区中唯一标识UE，第二DUI可以在第二超级小区中唯一标识UE。具体地，DUI可以是C-RNTI，hyper cell ID,TP ID，cell ID，新定义的ID等标识的任一个或者任意组合。
在某些实现方式中，UE支持的非小区模式也可以称为非普通小区模式，或超级小区模式，UE支持的小区模式也可称为普通小区(normal cell)模式。在普通小区模式下，网络侧可以通过UE的服务小区的切换对UE进行移动性管理，在超级小区模式下，网络侧在超级小区内基于UE的TP集合(第一TP集合和/或第二TP集合)对UE进行移动 性管理。
由于同一个或不同的hyper cell下的TP频段可能不同，本着网络尽量对UE透明的原则，在某些实现方式中，可以引入两个锚点频段：
锚点频段一：用于UE接收paging和/或进行下行同步等，这里为方便描述，称之为寻呼(paging)频段(或者叫下行同步频段)；
锚点频段二：用于UE发送上行参考信号，即使是不同频段的TP，也可监视同一个频段，这里为方便描述，称之为参考信号频段。
这两个频段可以是“固定不变”的，比如，可以是整个网络均使用这两个频段，在该网络中的UE移动到哪里都是这两个频段。或者，这两个频段可以在一定的范围内是固定的，比如在非小区模式时，网络将锚点频段的配置信息发送给UE；锚点频段引入的好处是，即使在移动的情况下，UE不需要关心周边网络的频段情况，UE只需要做两件事，一是在“固定”的paging频段上监听是否有自己的paging，可选地，也可以基于paging频段进行下行同步，同步的目的是为了在参考信号频段上发送paging；二是在“固定”的参考信号频段上发送上行参考信号。应注意，锚点频段的机制也可以适用于激活态的UE与网络之间的通信。处于节电态的UE发送上行参考信号的方式可以是：周期发送上行参考信号，或者为了省电，在检测到UE移动了一定的距离后发送上行参考信号；或者二者的结合，即在检测到移动了一定的距离后发送上行参考信号，并且在周期时间到后也发送上行参考信号。
本申请采用UE发送上行参考信号，网络侧测量的方式对UE进行移动性管理，并由网络侧为UE维护和更新用于UE数据传输(或数据通信)的第二TP集合，降低了UE的负担和热点区域移动性管理的难度。

具体实施方式
应理解，本发明的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、5G等。
还应理解，在本发明实施例中，用户设备(User Equipment，UE)包括但不限于移动台(Mobile Station，MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、手机(handset)及便携设备(portable equipment)等，该用户设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，例如，用户设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等，用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
如图1所示，hyper cell可以配置有hyper cell ID，且hyper cell可以包括同频和/或异频的多个TP(可选地，作为一个实施例，hyper cell中也可仅包括1个TP)，或者，hyper cell可以包括多个小区(可选地，作为一个实施例，hyper cell中也可仅包括1个小区)。可以理解的是，hyper cell内的TP(或者小区)的ID与hyper cell的ID可以保持一致，也可以分别配置。UE在hyper cell中移动，如果仍采用现有技术的移动性管理方式，由于每个TP均会对应一个或多个小区(或small cell)，导致该UE会频繁的进行小区切换。本发明实施例中，一般地，hyper cell内的TP的公共信息可以配置成一致，比如同步信道，下行参考信道，广播信道等信道发送的内容相同，UE在hyper cell内移动时，由于hyper cell内的TP的公共信息相同，UE对服务小区的变化无感知。比如，具体地，UE无需测量hyper cell中的各小区发送的下行参考信号，相反，由UE发送上行参考信号，网络侧测量UE的上行参考信号，并基于测量结果为UE选择一个或多个TP进行数据传输。也就是说，UE在hyper cell移动的过程中，测量上行参考信号、TP切换的任务可以由网络侧完成，尽量让UE不感知TP的变换，相当于引入“no cell”的工作模式，这样不但能够保证业务的连续性，而且能够减少空口信令的开销，UE无需承担繁重的测量任务，设计复杂度也相应降低。
应理解，“no cell”的工作模式可以指：由UE负责发送上行参考信号，由网络侧不断更新和维护为UE提供数据通信服务的TP，使得UE尽量不感知TP的变化。应理解，这里的“cell”是指现有技术中的普通小区，即normal cell，本申请中的“no cell”的工作模式也可称为超级小区的工作模式。
在超级小区中，会为UE分配DUI，超级小区可以根据DUI识别UE。例如，超级小区中TP可以基于DUI为UE提供数据通信服务；超级小区中的TP还可以基于DUI测量UE发送的上行参考信号。具体地，DUI可以是C-RNTI，hyper cell ID,TP ID，cell ID，新定义的ID等标识的任一个或者任意组合。
应理解，本发明实施例对TP的具体类型不作限定，例如，可以是普通的基站(如NodeB或eNB)，可以是射频拉远模块，可以是微基站(pico)，可以是中继(relay)或者任何其它无线接入设备。
可选地，作为一个实施例，可以由TP向RAN controller上报其是否支持no cell能力，再由RAN controller对支持no cell能力的TP进行no cell配置。这里的no cell能力可以指TP在超级小区中工作所需的各种能力，例如测量UE发送的上行参考信号的能力等。
以TP的上行参考信号的测量能力的配置方式为例进行举例说明。首先，RAN controller可以向TP发送测量配置信令(或称测量控制信令)。具体地，可以通过该测量配置信令配置以下测量配置参数中的至少一种：DUI、上行参考信号配置、携带测量标识、测量事件名称、测量间隔、测量报告上报模式、测量上报条件、测量参数。此外，可以为每个DUI(或每个UE)配置一套测量配置参数，也可以为超级小区中的全部DUI(或全部UE)共同配置一套测量配置参数。进一步地，测量参数可以包括：上行参考信号的接收质量、上行参考信号的接收功率、信噪比、信号与干扰和噪声比、路损等中的至少一种。测量配置参数还可以包括上述各项参数的门限中的至少一种。当TP检测的测量参数满足测量上报条件时，TP发送测量报告，并在测量报告中包含相应的测量结果。测量报告上报模式可以包括：事件触发的上报模式、周期性的上报模式，事件触发上报和周期性上报相结合的模式中的至少一种。其中，事件触发的上报模式可以指：当TP测量到的上行参考信号满足测量配参数中的门限时，TP向RAN controller发送测量报告。周期性的上报模式可以指TP周期性向RAN controller发送测量报告。
当RAN controller为TP配置了上行参考信号的测量配置参数之后，TP就可以依据该测量配置参数对UE发送的上行参考信号进行测量，并依据测量上报模式，将测量结果上报至RAN controller。
需要说明的是，该测量配置信令可以指示TP进行同频测量，也可以指示该TP进行异频测量。或者，RAN controller可以向TP发送同频测量的测量配置信令，也可以向TP发送异频测量的测量配置信令。具体而言，假设TP的工作频点为F1，UE发送参考信号的频点为F2，RAN controller可以指示TP进行异频测量，即指示TP在F2上测量UE发送的上行参考信号。或者，作为另一种实现方式，RAN controller也可以指示UE在TP的工作频点，即F1频段发送上行参考信号，然后指示TP进行同频测量。这样，TP仅需要在自己的工作频段测量上行参考信号即可。应理解，以上两种测量方式可以单独使用，也可以结合使用，本发明实施例对此不作具体限定。
当RAN controller收到各TP上报的测量报告，可以根据各TP上报的测量报告判断是否更新为UE传输数据的TP集合。具体地，RAN controller可以把各TP上报的测量结果和当前为UE传输数据的TP集合上报的测量结果逐一对比，还可以是逐一把各TP上报的测量结果和当前为UE传输的TP集合中TP上报的测量结果的差值或者绝对差值与某一门限做对比，还可以把各TP上报的测量结果和当前为UE传输数据的TP集合上报的测量结果的平均值逐一做对比，还可以是逐一把各TP上报的测量结果和当前为UE传输的TP集合中TP集合上报的测量结果的差值或者绝对差值与某一门限做对比，根据比对结果判断是否更新为UE传输数据的TP集合。
举例说明，假设测量参数为参考信号的接收质量；当前为UE传输数据的TP集合包括TP1和TP2；RAN controller分别给TP1，TP2，TP3，TP4分配了测量任务，即当参考信号的接收质量高于某一门限时，向RAN controller发送测量报告。RAN controller收到了TP1，TP2，TP3分别上报的参考信号的接收质量。RAN controller可以依据下述方式判断是否更新为UE传输数据的TP集合：
方式一、直接把TP3加入为UE传输数据的TP集合中，即将为UE传输数据的TP集合更新为TP1，TP2，TP3；
方式二、把TP3上报的参考信号接收质量分别与TP1，TP2上报的结果对比，如果TP3的结果高于TP1，TP2中的至少一个，或者如果TP3和TP1上报的参考信号接收质量的差值或者绝对差值高于某一门限，或者如果TP3和TP2上报的参考信号接收质量的差值或者绝对差值高于某一门限，RAN controller可以把TP3添加到为UE传输数据的TP集合中，或者，RAN controller也可以用TP3替换TP1或TP2；
需要说明的是，如果TP1和TP2属于RAN controller 1，TP3和TP4属于RAN controller2，TP3上报的测量报告可以通过RAN controller 2转发。为了避免RAN controller 1收到TP1和TP2的测量报告和收到的RAN controller 2转发的TP3的测量报告存在较大的时间差异，可以在测量报告中引入时间信息，用于指示测量结果记录的时间。应理解，RAN controller 2可以转发收到的全部测量报告，也可以基于一定策略，比如对测量结果进行比较后，仅选择一部分测量报告进行转发。
当RAN controller确定更新为UE传输数据的TP集合时，可以通过以下方信令或信息中的至少一种通知UE：无线资源控制RRC信令，L1信令，L2信令，下行控制信息(Downlink Control Information，DCI)。
需要说明的是，本发明实施例对UE发送的供网络测量的信号的名称、种类、形式不作具体限定，下文均以UE发送上行参考信号为例，但本发明实施例不限于此，例如，可以是新引入的用于跟踪UE位置的跟踪信号，也可以沿用探测参考信号(Sounding Reference Signal，SRS)。
在hyper cell的基础上，为hyper cell中的UE引入节电态和激活态两种状态。应理解，这里所说的节电态和激活态是为了与现有技术中的空闲态和连接态区分开，但本发明实施例不排除引入超级小区后，却仍沿用空闲态和连接态这种称呼的情况，在这种情况下，本发明实施例中的激活态可对应于连接态，本发明实施例中的节电态可以对应空闲态，也可以对应连接态。还可以理解的是，作为一种新的UE状态，节电态可以独立于hyper cell单独存在，即节电态也可以适用现有技术，但又区别于现有技术中的空闲态和连接态。下面对UE在这两种状态下的功能和特性进行详细描述。
节电态的UE继续保留该UE的DUI，并可以具有以下功能中的部分或全部：
1、可以处理一些背景业务和小包传输。
2、可以支持下行免调度(DL Scheduling-free)传输，即可以使用下行共享资源。
3、可以支持上行免授权(UL grant-free)传输，即可以使用上行共享资源。
4、可以不监测动态控制信道。
5、可以进行少量的连接管理(如长周期的链路自适应、长周期的测量)。
6、可以保留和网络侧的RRC连接；
7、可以保留与核心网的信令面承载和用户面承载；或者，可以仅保留与核心网的信令面承载，删除与核心网的用户面承载。当有上行背景业务或小包数据需要传输时，可以通过与核心网的信令面承载发送，比如，可以通过接入层的信令携带数据包，或者通过非接入层(Non-access stratum，NAS)信令携带数据包，该数据包传输到移动性管理实体(Mobility Management Entity，MME)后，MME识别其为背景业务或小包数据，转发给服务网关(Serving Gateway，SGW)；可选地，作为一种实现方式，节电态UE可 以保留与核心网的信令面承载，删除与核心网的专用用户面承载，建立与核心网的公用或缺省用户面承载。当有上行背景业务或小包数据需要传输时，可以通过与核心网的公用或缺省用户面承载进行传输。
8、发送上行参考信号，可以是周期性发送，也可以是满足事件触发条件后发送。事件触发条件可以是基于UE的速度触发，比如网络侧配置的当前发送周期为T，UE的速度门限为V。当UE速度小于和/或等于V时，UE可以自动延长上行参考信号的发送间隔为N*T，N＝2,3,……。进一步地，如果UE静止，上行参考信号的发送周期可以配置为无限大，具体实现时，可以配置参考信号的最大发送周期，比如256s，30min等。或者，事件触发条件也可以是基于UE检测到其它hyper cell后触发，比如UE移动到多个hyper cell的覆盖重叠区域，UE除了检测到当前所处的hyper cell的ID，还检测到另一hyper cell的ID，此时，UE可以发送上行参考信号。
激活态的UE具有DUI，并可以具有如下功能的部分或全部：
1、可以处理交互、会话类业务
2、可以支持UE使用上下行共享资源和专用资源
3、可以支持快速连接管理(如快速链路自适应、短周期测量)
如上所述，UE有两种状态，并且可以在这两种状态之间进行转换，如当UE数据传送完毕后一段时间再没有业务数据传输，该UE可以从激活态转到节电态；在节电态，UE可以不监测动态控制信道，只需支持少量的连接管理，其耗电会比激活态少。
可选地，在一个实施例中，可以由UE通过测量某个参数或指标来确定是否在节电态与激活态之间进行转换。例如，当测量到某个参数或指标满足门限时，UE向网络侧发送指示信息，然后，网络侧可以根据该指示信息控制UE进行状态转换。具体地，RAN controller可以预先向UE下发一个门限值，该门限值例如可以是UE的缓存数据大小的门限；当UE的缓存数据超过该门限值时，UE向RAN controller上报测量报告，然后RAN controller控制UE进行状态转换。或者，RAN controller可以向UE发送测量指示，在该测量指示的作用下，当UE测量到其缓存数据大小超过了当前允许发送的数据大小时，UE向RAN controller上报测量报告，然后，RAN controller控制UE进行状态转换。UE的指示信息可以通过L2信令上报，也可以通过RRC信令，比如测量报告进行上报，还可以在初始发送的数据中上报，比如通过初始发送的数据块中的某一个指示位进行指示，比如指示位设为TRUE进行指示,本发明实施例对此不作具体限定。
可选地，在一个实施例中，网络侧可以通过RRC信令指示UE进行激活态或节电态。例如，可以在RRC信令中增加新的状态指示信元，该状态指示信元可以指示UE进入节电态或激活态，UE可以根据该状态指示信元的指示进入相应的状态。
继续参见图1，UE在位置1时，可以由区域1中的TP形成的TP集合(也可称为TP簇)传输UE的数据(或为UE提供通信服务)，当用户设备从位置1移动至位置2时，可以由区域2中的TP形成的TP集合为UE提供。也就是说，在UE的移动过程中，为UE传输数据的TP可以是不断更新的，而该更新的任务可由网络侧基于UE发送的上行参考信号完成。需要说明的是，可以根据业务是UE的上行业务还是UE的下行业务，可以将UE的TP集合可以分为UL TP集合和DL TP集合。UL TP集合的更新可以由网络侧基于UE发送的上行参考信号完成。DL TP集合的更新可以由网络侧基于UE发送的上行参考信号完成，或者，可选地，作为一个实施例，也可以由网络侧根据UE上报的 基于下行参考信号的测量结果进行更新。
图2是本发明实施例的应用于hyper cell的通信方法的示意性流程图。应理解，图2示出了应用于hyper cell的详细的通信步骤或操作，但这些步骤或操作仅是示例，本发明实施例还可以执行其它操作或者图2中的各种操作的变形。此外，图2中的各个步骤可以按照与图2呈现的不同的顺序来执行，并且有可能并非要执行图2中的全部操作。
在图2的实施例首先为UE引入了两种工作模式：小区模式(也可称为normal-cell模式或network-centric模式)和非小区模式(no cell mode或者称为UE-centric模式)。在小区模式下，可以采用现有技术的移动性管理方式，即网络发送下行参考信号，UE测量下行参考信号并反馈测量报告，网络侧基于测量报告进行小区切换；在非小区模式下，可以由UE发送上行参考信号，网络测量UE的上行参考信号，然后基于测量结果不断更新用于传输UE数据的TP集合。但应理解，引入这两种工作模式主要是考虑到灵活性和兼容性问题，本发明实施例不排除以非小区模式完全替代小区模式，或者在hyper cell中仅以小区模式进行移动性管理的可能性，在这种情况下，可以无需为UE选择工作模式，直接采用非小区模式为UE提供服务。
此外，图2的实施例中，由无线接入网的控制器(Radio Access Network controller，RAN controller)为UE提供移动性管理，该RAN controller可以是接入网侧的独立的网元，但本发明实施例不限于此。例如，RAN controller可以与TP集合成在同一实体中，比如称之为接入网设备，TP可以是该接入网设备的发射和接收单元；或者，RAN controller也可以是TP，该TP可以是或不是为UE提供数据传输服务的TP集合中的TP，当是的时候，RAN controller可以直接发送信令给UE。
下面描述图2的具体步骤。
202、UE发起初始接入，执行无线资源控制(Radio Resource Control，RRC)连接建立流程。
在RRC连接建立过程中，可以携带相关的参数给网络，这些参数可以包括：UE的速度、UE的位置、检测到的周边小区的信号情况、业务信息等中的至少一个。这些参数可以是通过UE的全球定位系统(Global Positioning System，GPS)，或其他方式测量得到的参数。
204、hyper cell向核心网(Core Network，CN)发送初始UE消息。
206、CN向hyper cell发送初始上下文建立请求。
在步骤204和206中，hyper cell为UE建立与CN的连接，在以上过程中，hyper cell可以从UE或CN获取到UE类型或UE能力等信息。具体来说，UE类型可以是该UE是否为固定位置的UE，比如传感器，该UE是否耗电敏感等。UE能力例如可以是UE是否支持非小区模式，UE支持哪些频段等。
208、hyper cell向RAN controller发送消息，请求RAN controller确定UE的工作模式。
在步骤208中，hyper cell向RAN controller发送的消息中可以携带通过步骤202至206获得的UE的信息，例如，可以是UE的系统架构演进临时移动用户身份(System Architecture Evolution Temporary Mobile Subscriber Identity，S-TMSI)，UE的移动速度，UE的位置，UE类型，UE能力、UE的业务信息等。
210、RAN controller确定UE的工作模式。
RAN controller可以基于hyper cell在步骤208中提供的信息确定UE的工作模式。例如，RAN controller基于接收到的信息获知UE的大概位置、移动速度等，然后基于该位置周边的网络部署情况确定是否适合采用非小区模式，如果适合采用非小区工作模式，并且UE支持非小区模式，则可以将UE的工作模式确定为非小区模式。
212、RAN controller与hyper cell内的TP进行资源协调。
步骤212中，RAN controller可以基于获取到的UE的信息(如UE的位置、UE的速度、UE的类型等)为UE分配第一TP集合和第二TP集合，并与这些TP进行资源协调，其中，每个TP集合包括一个或多个TP。第二TP集合中的TP可用于UE的数据传输，因此，第二TP集合也可称为UE的传输TP集合，或传输簇，第一TP集合中的TP可用于测量UE发送的上行参考信号，因此，第一TP集合也可称为UE的测量TP集合，或测量簇。
具体而言，第一TP集合和第二TP集合中的TP可以是UE周边的TP，一般来说，第二TP集合可以为第一TP集合的子集。如图3所示，在UE的当前位置中，第一TP集合包括第二TP集合。可选地，作为一个实施例，第一TP集合可以包括第二TP集合以及该第二TP集合周边一层TP。需要说明的是，也可以将hyper cell中的所有TP形成的TP集合设置为UE的第一TP集合，这种情况下，hyper cell中的所有TP均需要去测量UE发送的上行参考信号，这种设置方式可能会使网络的负担比较大，因此，作为一个实施例，可以从hyper cell中选取至少一个TP形成UE的第二TP集合和第一TP集合，然后可以基于UE位置的移动动态更新该UE的第二TP集合和第一TP集合。
214、RAN controller向第二TP集合和第一TP集合中的TP发送非小区配置(no cell configuration)消息。
该非小区配置消息可指示第二TP集合中的TP为UE提供服务，指示第一TP集合中的TP测量UE发送的上行参考信号，该非小区配置消息可包括UE的S-TMSI，可选地，作为一个实施例，该非小区配置消息还可包括RAN controller为UE分配的DUI，该DUI可用于在该超级小区中标识该UE(或唯一标识该UE)。
可选地，作为一个实施例，UE的DUI与UE发送上行参考信号的时频资源(或称时频序列)之间可以具有对应关系，第一TP集合中的TP可以根据UE的DUI以及该对应关系，确定UE发送上行参考信号的时频资源，从而在该时频资源上测量该UE发送的上行参考信号。当然，本发明实施例并不限于此，例如，可以通过非小区配置信息向第一TP集合中的TP指示UE的上行参考信号所占的时频资源的位置。
可选地，作为一个实施例，如果UE的第二TP集合中TP发生了更新，比如TP4替换了原来的TP3，可以考虑TP4中的与UE相关的某些数据(如未发送成功的数据，已发送但未收到ACK的数据)的后续处理方式。具体地，如果TP4和TP3属于同一个hyper cell，RAN controller和TP3之间需要交互该UE的未发送的数据和已发送未收到ACK的数据；RAN controller根据TP3的反馈，把这些数据发送到TP4，由TP4发送给UE；UE根据RAN controller配置的HARQ反馈机制进行相应的反馈。如果TP4和TP3属于不同的hyper cell，可能还需要考虑UE的媒体介入控制(Media Access Control，MAC)实体的处理。例如，MAC实体1处理hyper cell 1收到的数据，在配置TP4(属于hyper cell2)为UE提供数据服务时，可以携带MAC实体1和2个hyper cell(hyper cell 1和hyper cell2)间的映射关系，以指示MAC实体2处理TP4的数据；UE可以识别TP所属的hyper cell， 当UE收到网络侧的配置指示替换的TP属于不同的hyper cell时，UE可以清空从TP3接收的缓存数据。当然,在时延理想的网络架构中，TP可能只包含物理层PHY，MAC及其上层位于BBU-pool侧，因此仅当BBU-pool发生改变时才将触发上述数据转发过程。对于时延不理想的网络架构，则可能只有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)位于基带处理单元(Baseband Unit，BBU)-pool侧，其它协议层均在TP侧(或者所有协议层均在TP侧)，此时每切换一个TP都将涉及RRC重配置过程。
可选地，作为一个实施例，为了减少切换过程中的用户面数据传输的中断时延，可以在各TP预存储发送给UE的数据。当为UE传输数据的TP集合发生变化时，UE根据网络配置完成相关重置过程，比如完成RRC、PDCP、无线连接控制(Radio Link Control，RLC)、MAC、PHY中的至少一个协议层的重置过程，向网络发送当前缓存数据的指示消息。所述指示消息可以通过如下消息或信令中的至少一种发送：服务请求消息、重配置完成信令、通过L2信令、上行物理控制和数据信道。所述指示消息中可以携带当前的数据缓存情况，例如，可以携带协议层的标识(该协议层可以是RRC、PDCP、RLC、MAC、PHY等协议层中的至少一个)及该协议层中的数据对应的HARQ信息，使得新的TP可以根据该指示消息唯一识别数据，并根据相应的HARQ信息(包含数据的ACK或NACK信息)对UE进行数据传输。以UE仅更新接收数据的端口号，或者说UE仅执行PHY协议层重置为例，UE可以向网络侧发送指示消息，并可以在指示消息中携带PDCP、RLC以及MAC中的一个或多个的标识信息，该指示消息还可以携带该标识信息对应的协议层中的数据的HARQ信息。新的TP收到上述指示消息，对NACK信息进行重新传输。可选地，新的TP向原TP发送确认信息，指示原TP停止向UE发送数据。
216、RAN controller通过TP向UE发送非小区配置消息。
该非小区配置消息可用于指示该UE在该超级小区中采用非小区模式工作。可选地，作为一个实施例，该非小区配置消息可以包括该UE的DUI。UE可以利用该DUI与第二TP集合中的TP进行数据传输。可选地，该非小区配置消息包含第一TP集合中的TP的信息。
218、hyper cell向CN发送初始上下文建立完成消息。
接下来，UE就可以工作在非小区模式，与RAN controller为其分配的第二TP集合进行数据通信，并发送上行参考信号，供第一TP集合进行测量。
220、UE发送上行参考信号。
UE的上行参考信号的时频资源位置可以由步骤216中的小区配置消息指示，可选地，作为一个实施例，可以预先建立UE的专用用户标识与上行参考信号时频资源的对应关系，UE可以基于该对应关系，确定发送上行参考信号的时频资源。
在一个实施例中，上述上行参考信号可以是SRS。在一个实施例中，该上行参考信号可以周期发送，或者UE移动一段距离后发送，距离长短可以是网络配置的，或者上述两种发送方式的结合，即在检测到移动了一定的距离后发送，并且在周期时间到后也发送。
222-224、第一TP集合中的TP测量UE发送的上行参考信号，并将测量报告上报至RAN controller。
RAN controller可以基于第一TP集合或第二TP集合中的TP上报的测量报告，不断调整或更新第二TP集合(或表述为不断调整或更新第二TP集合的成员，例如，将其他 TP加入第二TP集合或者删除第二TP集合中的某个成员)。在一个实施例中，RAN controller还可以不断调整或更新第一TP集合(或表述为不断调整或更新第一TP集合的成员，例如，将其他TP加入第一TP集合或者删除第一TP集合中的某个成员)。
具体地，当第二TP集合中的某个TP测量到的UE的上行参考信号变差时，比如，低于某个门限，可以将该TP从第二TP集合中删除；当第一TP集合中的某个TP检测不到上行参考信号(或者检测到的上行参考信号低于一定的门限)并满足一定的条件(比如其周边的一层TP也检测不到该UE的上行参考信号或检测到的上行参考信号低于一定的门限)，则可以将该TP从第一TP集合中删除；当第一TP集合中的某个TP测量到UE的上行参考信号时(或者测量到UE的上行参考信号高于某个门限时)，可以将其周边的一层TP加入到第一TP集合中；当第一TP集合中的某个TP测量到UE的上行参考信号并且信号强度足够好时(也就是，测量到UE的上行参考信号高于配置或设置的门限时，或者测量到的UE的上行参考信号与第二TP集合TP上报的测量结果或平均测量结果的差值或者绝对差值逐一做对比，且所述差值或所述绝对差值小于某一门限时)，可以将该TP加入到第二TP集合中，可选地，RAN Controller可以将该加入第二TP集合中的TP通过以下信息或信令中的至少一种通知UE：RRC信令，L1信令，L2信令和DCI。
226、RAN controller确定UE工作在小区模式。
RAN controller可以根据第一TP集合上报的测量报告，判断UE不再适合工作在非小区模式，例如，UE即将移出hyper cell的范围，并且UE即将进入的小区为普通小区，此时，RAN controller可以将UE的工作模式切换为小区工作模式。
228-230、RAN controller通过TP向UE发送非小区释放消息。
该非小区释放消息可用于指示UE进入小区模式。该小区释放消息中可携带服务小区的频率和/或cell id，用于指明UE在小区模式时的服务小区。在一个实施例中，该频率和/或cell id可以是当前第二TP集合下的一个TP对应的小区。在一个实施例中，非小区释放消息可以指示多个服务小区的频率和cell id，例如，多个服务小区中的某个小区可以是主小区，其他小区为辅小区，这样UE可以在小区模式下进行载波聚合。
232、UE切换至小区模式，并与服务小区进行通信。
本发明实施例中，网络能够灵活配置UE的工作模式，控制UE在非小区模式和小区模式之间灵活转换，提高了网络性能。
在图2的实施例中，UE可以是处于激活态的UE，下面结合图4，详细描述hyper cell中的处于节电态的UE(或ECO态的UE，ECO表示Ecology(生态)，Conservation(节能)、Optimization(优化)，或称为空闲态的UE)的寻呼以及进入激活态(或称为连接态)的方式。
现有的以网络为中心的设计思想中，处于节电态的UE仍会测量各小区的上行参考信号，基于测量结果进行小区重选，尽量选择驻留在信号条件好的小区。当UE需要进行数据传输时，该UE会在当前驻留的小区发起RRC连接，从而进入激活态。图4的实施例中，处于非小区模式的节电态的UE以hyper cell为单位选择驻留，并且预先配置了上行资源，当需要传输数据时，该UE可以利用预先配置的上行资源快速进入激活态，无需重新发起复杂耗时的RRC连接。下面结合具体的流程详细描述。
图4是本发明实施例的应用于hyper cell的通信方法的示意性流程图。应理解，图4示出了应用于hyper cell的详细的通信步骤或操作，但这些步骤或操作仅是示例，本发明 实施例还可以执行其它操作或者图4中的各种操作的变形。此外，图4中的各个步骤可以按照与图4呈现的不同的顺序来执行，并且有可能并非要执行图4中的全部操作。
步骤404之前可以执行图2中的部分或全部步骤，如步骤402与步骤202类似，为避免重复，此处不再详述。
404、UE接收到网络侧发送的进入节电态的指示信息。
例如，当UE的业务不频繁或几乎没有业务时，网络可以指示UE进入节电态(或ECO态)。可选地，该指示信息可以携带节电态的配置参数。具体地，该配置参数可以包含如下参数中的至少一种：
参数1、指示处于节电态的UE的工作模式为非小区模式的参数。
应理解，该参数是可选的，例如，无需配置该参数，使UE在节电态的工作模式与UE在激活态的工作模式保持一致即可。此外，如果处于空闲的UE的工作模式为小区工作模式，该UE可以参照现有的方式进行寻呼和进入激活态，此处不再详述。
参数2、指示UE的寻呼时机的参数。
寻呼时机可以指UE接收寻呼消息或发送寻呼响应消息的时频资源等参数。作为一个实施例，该寻呼时机相关的参数可以与UE在hyper cell下的专用用户设备标识相关联，即UE可以根据专用用户设备标识确定寻呼时机。
参数3、用于UE快速恢复(或快速进入激活态)的参数。
该参数可以指示预配置给UE的上行资源，如可以是调度资源(Scheduling Resource，SR)，物理上行共享信道(Physical Uplink Shared Channel，PUSCH)，或者上行竞争资源等。在一个实施例中，该用于UE快速进入激活态的参数也可以与UE的专用用户设备标识相关联，UE可以根据自己的专用用户设备标识以及该关联关系确定为其分配的调度资源，然后利用该调度资源快速进入激活态，无需经过复杂的RRC连接建立过程。
参数4、时间提前量(Timing Advance，TA)相关的配置参数。
例如，为UE提供初始的TA值，进入激活态后，UE可以利用该初始的TA值发送上行数据。
406、进入节电态的UE发送上行参考信号。
具体地，节电态的UE可以继续保留专用用户设备标识，继续发送上行参考信号，并监听寻呼消息。由于同一个或不同的hyper cell下的TP频段可能不同，本着网络尽量对UE透明的原则，在某些实现方式中，可以引入两个锚点频段：
锚点频段一：用于UE接收paging和/或进行下行同步等，这里为方便描述，称之为寻呼(paging)频段(或者叫下行同步频段)；
锚点频段二：用于UE发送上行参考信号，即使是不同频段的TP，也可监视同一个频段，这里为方便描述，称之为参考信号频段。
这两个频段可以是“固定不变”的，比如，可以是整个网络均使用这两个频段，在该网络中的UE移动到哪里都是这两个频段。或者，这两个频段可以在一定的范围内是固定的，比如在非小区模式时，网络将锚点频段的配置信息发送给UE；锚点频段引入的好处是，即使在移动的情况下，UE不需要关心周边网络的频段情况，UE只需要做两件事，一是在“固定”的paging频段上监听是否有自己的paging，可选地，也可以基于paging频段进行下行同步，同步的目的是为了在参考信号频段上发送paging；二是在“固定”的参考信号频段上发送上行参考信号。应注意，锚点频段的机制也可以适用于激活态的 UE与网络之间的通信。处于节电态的UE发送上行参考信号的方式可以是：周期发送上行参考信号，或者为了省电，在检测到UE移动了一定的距离后发送上行参考信号；或者二者的结合，即在检测到移动了一定的距离后发送上行参考信号，并且在周期时间到后也发送上行参考信号。
408-410、第一TP集合中的TP将UE的上行参考信号的测量报告发送至RAN controller，RAN controller基于测量报告不断调整或更新第一TP集合中的TP。
例如，当第一TP集合中的某个TP检测不到UE发送的上行参考信号并满足一定条件，比如该TP周边一层TP也检测不到上行参考信号，可以从第一TP集合中删除该TP。又如，当第一TP集合合中的某个TP检测到UE发送的上行参考信号时，可以将其周边一层TP也加入到第一TP集合中。
412、RAN controller接收到UE的数据。
414-416、RAN controller通过TP向UE发送paging消息。
具体地，RAN controller可以从第一TP集合中选取信号质量较好的一个或多个TP，并通过这些TP，在paging频段向UE发送paging消息。paging消息中可以携带该UE的标识。可选地，作为一个实施例，用于UE快速进入激活态的上行资源可以携带于该paging消息中。可选地，在一个实施例中，当发送的下行数据比较小时，可以通过paging消息直接将该下行数据发送至UE，无需UE进入激活态，这样可以避免UE频繁地进行激活态和节电态的转换。
418-420、UE通过TP在预配置的上行资源向RAN controller发送paging响应消息。
如上文所述，该预配置的上行资源可以是通过步骤404中的指示信息指示，可以与UE的专用用户设备标识关联，或者可以由步骤414-416中的paging消息指示，本发明实施例对此不作具体限定，UE通过该预先分配的上行资源发送paging响应消息，无需发起RRC连接建立过程而快速进入激活态。
图2至图4的描述均涉及RAN controller对UE相关的TP集合的更新、管理与维护，下文结合具体的实施例，更加详细地描述相关内容。
应理解，UE相关的TP集合包括UE的第二TP集合(用于传输UE的数据，或称为UE的传输簇)和第一TP集合(用于测量UE发送的上行参考信号，或称为UE的测量簇)。RAN controller可以为激活态的UE维护第二TP集合和第一TP集合，由于节电态的UE无需数据传输，RAN controller可以仅维护该UE的第一TP集合。当然，第一TP集合可以包括hyper cell的至少一个TP，如果第一TP集合包括hyper cell的全部TP，那么第一TP集合无需更新，但hyper cell的全部TP全部测量UE的上行参考信号，这种做法会加大网络侧的负担，因此，可以将第一TP集合仅包括hyper cell的部分TP，然后随着UE的移动不断更新该第一TP集合即可。下面结合图5详细描述TP集合中的TP的添加和删减流程。
图5是本发明实施例的应用于超级小区的方法的示意性流程图。应理解，图5示出了应用于hyper cell的详细的通信步骤或操作，但这些步骤或操作仅是示例，本发明实施例还可以执行其它操作或者图5中的各种操作的变形。此外，图5中的各个步骤可以按照与图5呈现的不同的顺序来执行，并且有可能并非要执行图5中的全部操作。
参见图5，RAN controller可以通过消息，比如非小区配置消息删除或添加第二TP集合中的TP，该消息中可以携带UE的DUI，可选地，当删除或添加第一TP集合中的 TP时，RAN Controller通过信令消息知会UE被网络删除或添加的第一TP集合中的TP，比如发送被删除或添加的TP信息，或者发送执行删除或添加后的第一TP集合中还包含的TP信息。RAN controller可以通过参考信号测量指示消息删除或添加第一TP集合中的TP，该消息可以携带UE的专用用户设备标识。可选地，作为一个实施例，参考信号测量指示消息中还可以携带上行参考信号的配置消息，指示UE发送的上行参考信号的时频资源，当然，这仅是上行参考信号配置确定方式的一个举例，此处也可以沿用上文已经描述过的UE的专用用户设备标识和上行参考信号的时频资源相关联的方式确定上行参考信号，本发明实施例对此不作具体限定。
一般情况下，空口传输的数据均需要进行安全保护，例如，可以为空口传输的数据加密。如上文所述，RAN controller为UE分配了用于传输UE数据的第二TP集合，如果由第二TP集合中的各个TP分别对UE的数据进行加密，这样整个系统的效率会比较低。为了使得整个系统更加简单有效，可以在网络侧引入一个统一为UE的数据提供加密服务的数据锚点，这个数据锚点例如可以是服务网关。
当UE的第二TP集合中的某个TP从该第二TP集合中删除时，如果该TP还存在UE的未发送成功的下行数据，本发明实施例提供图6所示的通信流程，以减少UE数据的丢失。
602、RAN controller向TP2发送参考信号测量指示消息。
具体地，RAN controller通过参考信号测量指示消息指示TP2测量UE发送的上行参考信号，说明RAN controller将TP2添加到了UE的第一TP集合。
604-606、TP2测量UE的上行参考信号，并向RAN controller发送测量报告，指示测量到的UE的上行参考信号质量好。
608、RAN controller向TP2发送非小区配置消息，指示TP2被添加至UE的第二TP集合，可用于传输UE的数据。
610、RAN controller通知数据锚点TP2被添加至UE的第二TP集合。
具体地，由于数据锚点负责UE的数据的加密，并将加密后的数据经第二TP集合中的TP传至UE，因此，RAN controller可以通知数据锚点TP2已被添加至该第二TP集合，可以用来传输UE的数据。
612、TP2向RAN发送测量报告，指示测量到的UE的上行参考信号质量差。
614、RAN controller向TP2发送非小区配置消息，指示TP2已从UE的第二TP集合中删除，不再负责传输UE的数据。
616、RAN controller通知数据锚点TP2已从UE的第二TP集合中删除。
这样，数据锚点就不会将UE的加密后的下行数据发至TP2。
618、TP2将UE的未成功发送的下行数据发送至数据锚点。
620、数据锚点将TP2的未发送成功的下行数据转发至第二TP集合中的其它TP，由其它TP发送至UE。
本发明实施例不但保证了UE数据的安全，还有效避免了UE数据的丢失。
此外，需要说明的是，如果无线连接控制(Radio Link Control，RLC)层在TP节点上时，当增加一个新的TP，尤其是同频的TP时，比如，之前的为TPx，新增一个同频的TPy，由于新的TPy的RLC层序号从0开始，UE需要识别这是一个新的TP以区分TPx，从而正确接收数据，可能的方式包括：
方式一、在发送给UE的每个数据包中携带一个TP标识信息，每个TP发送给UE的数据包中携带自己的TP标识信息，UE基于该标识信息识别出是否是一个新的TP，从而从序号0开始接受该TP的数据；可选地，数据包中携带一个指示信息，用于指示UE删除某个TP，网络持续发送携带指示信息的数据包，直至网络确定UE成功接收到携带该指示信息的数据包后停止携带；或者，UE在预设的一段时间内没有收到TP的数据包(比如，预设时间由网络配置)，则删除该TP，同理，网络在相同时长的时间内没有发送TP的数据包，则下次再次发送时，RLC层序号从0开始发送；
方式二、在发送给UE的每个数据包中携带一个bit的TP更改标识，当更改标识发生改变时，UE获知一个新的同频TP服务于UE，从而释放旧的同频TP，新的TP从序号0开始，这种方法适用于同时只能有一个同频的TP与UE进行数据传输。
方式三、当一个新的TP被增加，或者一个新的TP替换掉另一个TP时，网络将新增TP信息通知UE，从而使得UE能获知在该新的TP上传输的承载的数据包的序号从0开始。
上文结合图1至图6，详细描述了UE在一个hyper cell中的通信过程，下文结合图7至图8，详细描述UE从hyper cell 1(第一超级小区)切换至hyper cell 2(第二超级小区)的过程，以保证业务的连续性。
图7是本发明实施例的应用于hyper cell的小区切换过程的示意性流程图。应理解，图7示出了应用于hyper cell的详细的通信步骤或操作，但这些步骤或操作仅是示例，本发明实施例还可以执行其它操作或者图7中的各种操作的变形。此外，图7中的各个步骤可以按照与图7呈现的不同的顺序来执行，并且有可能并非要执行图7中的全部操作。
702、hyper cell 1向UE发送非小区配置消息。
UE此时位于hyper cell 1，hyper cell 1向UE发送非小区配置消息，该消息可用于指示UE工作在非小区模式下。
704-706、UE发送上行参考信号，hyper cell 1中的TP将该上行参考信号的测量报告发送至RAN controller。
该步骤与上文中的步骤220-222类似，此处不再详述。
708、RAN controller根据hyper cell 1中的TP的测量报告，识别UE即将移动至hyper cell 2的覆盖范围。
例如，RAN controller发现hyper cell 1中的靠近hyper cell 2的一个或多个TP检测到UE的上行参考信号。
710、RAN controller向hyper cell 2中的TP发送参考信号测量指示消息。
该消息可以携带UE在hyper cell 1下的专用用户设备标识和/或UE的参考信号配置(可以指示UE在hyper cell1下发送的上行参考信号的时频资源和/或信号序列)。Hyper cell2中的这些TP可以是上述hyper cell1下TP的邻接TP。
712、hyper cell 2中的TP测量UE的上行参考信号，并将测量结果上报至RAN controller。
Hyper cell2下的TP测量UE在hyper cell1下配置的上行参考信号，当测量的信号强度满足测量报告触发条件，比如大于一定的门限，则将测量结果上报给RAN controller，所述的触发报告触发条件被包含在参考信号测量指示消息里；
714、RAN controller根据hyper cell 2中的TP的测量报告确定UE已进入hyper cell 2 的覆盖范围，更适合在hyper cell 2下进行数据传输，决定进行切换。
716、RAN controller向hyper cell 2中的TP发送新UE进入请求。
该新UE进入请求(New UE Enter Request)中可以携带UE在hyper cell 2下的专用用户设备标识，该专用用户设备标识可用于在hyper cell 2下唯一标识该UE，接收到该专用用户设备标识的TP可以为该UE提供通信服务。
718、hyper cell 2中的TP向RAN controller发送新UE进入响应。
例如，hyper cell 2中的TP通过响应消息表示接收UE进入hyper cell 2的请求。
720-722、RAN controller通过hyper cell 1中的TP向UE发送切换命令。
该切换命令可以携带UE在hyper cell 2中的专用用户标识。在一个实施例中，该切换命令还可以携带初始TA值。在一个实施例中，RAN controller还可以为UE衍生其在hyper cell 2下进行数据传输的密钥，并在切换命令中携带该新的密钥，同时RAN controller将该新的密钥发送至hyper cell 2对应的数据锚点，从而使得UE在hyper cell 2下使用新的密钥进行数据的安全保护。
724、UE在hyper cell 2中发送上行参考信号。
例如，UE接收到切换命令之后，可以使用新的专用用户设备标识对应的参考信号配置发送上行参考信号，以便hyper cell 2中的TP测量UE的信号质量，进而可以由RAN controller为UE分配其在hyper cell 2中的第二TP集合和第一TP集合。
上面描述的是处于激活态的UE在hyper cell之间的切换过程，而对于处在节电态的UE，其切换过程可以有以下两种方式：
方式一：UE识别其移动至一个新的hyper cell，该UE自己发起切换过程。
方式二：网络通过测量获知UE移动到新的hyper cell，网络发起切换过程。
对于方式一，参见图7的步骤726至736，详细描述如下：
726、UE确定进入新的hyper cell 2。
728、UE向hyper cell 2中的TP发起随机接入过程，或者在hyper cell之间共享的PUSCH上发送超级小区更新消息(hyper cell update message)，该消息可以携带UE在hyper cell 1中的专用用户设备标识，还可以携带hyper cell 1的标识。
730、hyper cell 2通知RAN controller有UE发起超级小区更新。
732-734、RAN controller为该UE分配其在hyper cell 2下的专用用户设备标识，并通过小区配置消息将该新分配的专用用户设备标识发送至UE。
736、RAN controller通知hyper cell 1中的TP释放该UE的相关配置。
对于方式二，其与处于激活态的UE的过程基本类似，不同点在于由于UE处于节电态，切换命令可以通过paging消息来传递，具体参见图8。
图8是本发明实施例的应用于hyper cell的小区切换过程的示意性流程图。应理解，图8示出了应用于hyper cell的详细的通信步骤或操作，但这些步骤或操作仅是示例，本发明实施例还可以执行其它操作或者图8中的各种操作的变形。此外，图8中的各个步骤可以按照与图8呈现的不同的顺序来执行，并且有可能并非要执行图8中的全部操作。
步骤804-818与图7中的步骤704-718类似，此处不再详述。
820-822、RAN controller通过寻呼消息，向UE发送切换命令。
该切换命令可以携带UE在hyper cell 2中的专用用户标识。在一个实施例中，该切换命令还可以携带初始TA值。在一个实施例中，RAN controller还可以为UE衍生其在 hyper cell 2下进行数据传输的密钥，并在切换命令中携带该新的密钥，同时RAN controller将该新的密钥发送至hyper cell 2对应的数据锚点，从而使得UE在hyper cell 2下使用新的密钥进行数据的安全保护。
824、UE在hyper cell 2发送上行参考信号。
