Abstract

本发明提供了一种确定小区的方法、用户终端及节点，该方法包括：首先，UE驻留在第一小区；UE接收第一小区对应的第一节点发送的指示消息；其次，UE根据指示消息确定第二小区；UE接收所述第二小区的第二***消息，并对所述第二小区进行测量因此，从而降低资源消耗和网络负荷，并且第一小区和/或第二小区对应节点可以为UE实现数据业务的传输，进而提高传输数据业务的效率。

Description

确定小区的方法、用户终端及节点 技术领域
本发明实施例涉及移动通信领域，尤其涉及一种确定小区的方法、用户终端及节点。
背景技术
一种新的网络部署正逐渐被引入到下一代无线网络中，即异构网络(HetNet)部署。在HetNet中，一些低功率节点被部署在宏小区(Macro Cell)的覆盖范围内，这些低功率节点(即微基站)可以是射频拉远头天线(Remote Radio Head，RRH)、小基站(Pico eNB)、家用基站、中继站(Relay Node，RN)和无线局域网接入点(Wifi Access Point)中的一种或几种，这些低功率节点的小区由于覆盖范围相比宏小区较小，可以被称为小小区(Small Cell)。这其中，宏小区可以为用户提供了无缝的覆盖，而这些小小区可以提高了***的容量。实际部署的时候，宏小区和小小区可以使用相同的频率，也可以使用不同的频率。这种宏基站和微基站共存的网络为异构网络。
宏基站和微基站均可以为用户终端(User Equipment，UE)服务，宏节点的小区通常被称为宏小区，微节点的小区通常被称为微小区，当空闲状态下的UE驻留在某个节点的小区内时，网络为了寻呼该UE以通知UE有业务或者通知UE建立连接传输业务，整个跟踪区域所包括的所有微基站和宏基站都会向UE发送寻呼消息。然而，UE只会在它所驻留小区中接收到寻呼消息。在异构网络中存在大量的微基站，由于整个跟踪区域(Tracking Area，TA)内的所有基站(包括宏基站和微基站)都发送寻呼消息来寻呼该UE，从而使得空口发送大量消息，进而造成资源浪费，加重了网络负荷。因此如何避免在异构网络下由于寻呼一个UE导致大量的基站发送寻呼消息给UE，造成空口信令风暴和资源浪费的问题，是本发明需要解决的问题。
发明内容
本发明提供一种确定小区的方法、用户终端及节点，从而在降低资源消耗和网络负荷的同时，进而使得UE总是处于信号质量好的小区实现数据业 务传输。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
图1为本发明实施例一提供的一种确定小区的方法的流程图，该方法可适用于用户终端确定传输数据业务的小区的场景，其中该方法的执行主体为 用户终端，该方法的具体流程包括：
S101：UE驻留在第一小区。
具体地，寻呼消息的目的具体可以是以下一种或者多种：第一种情况，为了传输寻呼信息给空闲态UE(to transmit paging information to a UE in RRC_IDLE)。例如寻呼消息可以用于在有业务时，网络寻呼UE，当UE收到该寻呼消息后可以建立无线资源控制(Radio Resource Control，RRC)连接，与基站进展业务传输),或者网络寻呼UE，例如移动管理实体(Mobility Management Entity，MME)发送寻呼消息给基站，后续基站发送寻呼消息的UE，用于通知UE有业务或者通知UE由空闲态转为连接态等。
第二种情况，为了通知连接态UE或者空闲态UE***消息有更新(to inform UEs in RRC_IDLE and UEs in RRC_CONNECTED about a system information change)，即寻呼消息用于通知UE由于发送该寻呼消息小区/节点的***消息更新，当UE收到用于指示***消息更新的寻呼消息后，UE会重新获得所有的***消息即重新把所有的***消息接收一遍(When the Paging message indicates system information changes then UE shall re-acquire all system information)。
第三种情况为了通知UE有关地震海啸***(Earthquake and Tsunami Warning System，ETWS)第一通知和/或ETWS第二通知(to inform about an ETWS primary notification and/or ETWS secondary notification)。即寻呼消息用于通知UE地震海啸***ETWS第一通知和/或ETWS第二通知所引起的寻呼消息。
第四种情况为了告知UE商用移动警报服务通知(to inform about a CMAS notification)，即寻呼消息用于告知UE商用移动警报通知(Commercial Mobile Alert Service，CMAS)。
第一种情况下，即当寻呼消息可以用于在有业务时，网络寻呼UE，当UE收到该寻呼消息后可以建立RRC连接，与基站进行进业务传输。这种情况，由于在整个TA区域内的基站都会发送寻呼消息，因此造成空口信令负荷比较大。第二种情况或第三种情况或第四种情况下，比如当寻呼消息用于通知UE发送该寻呼消息的小区的***消息发生更改时，可以由此指示UE去接收***消息或者更新***消息。而寻呼第二种情况中基站或者小区自身 由于***消息更新导致该基站在一个小区内发送寻呼消息用于通知本小区***消息更新，这种情况不会造成太多空口信令负荷，因此，为了降低资源消耗，则使得UE驻留在第一小区时接收第一种情况列举的寻呼消息，而在其他小区(例如微小区)不发送第一情况中举例的寻呼消息。
可选地，所述UE根据所述指示消息在确定第二小区的过程中或者确定第二小区之后，所述UE依旧驻留在所述第一小区；或者，所述UE在确定第二小区的过程中或者之后，所述UE进行所述第一小区的小区重选。
进一步地，所述UE，仅从所述第一小区，接收寻呼消息；或者所述UE在所述第一小区接收寻呼消息，并且所述UE在所述第二小区接收寻呼消息，所述UE在所述第二小区接收所述寻呼消息包括以下至少一种：用于通知所述第二小区的第二***消息更新的寻呼消息；用于通知有关地震海啸***ETWS第一通知和/或ETWS第二通知的寻呼消息；用于告知商用移动警报服务CMAS通知的寻呼消息。
第一，“所述UE，仅从所述第一小区，接收寻呼消息”可以理解为：对于第一小区(或者UE在第一小区执行第一小区重选时，重选确定后的新第一小区)和第二小区(或者UE在第二小区执行第二小区重选时，重选确定后的新第二小区)，UE只从所述第一小区(或者UE在第一小区执行第一小区重选时，重选确定后的新第一小区)接收寻呼消息，不从所述第二小区(或者UE在第二小区执行第二小区重选时，重选确定后的新第二小区)接收任何寻呼消息。其中UE在所述第一小区接收寻呼消息(可以是UE selects and monitors the indicated paging channels of the cell)，所述寻呼消息是用于以下的至少一种：
A)用于为了传输寻呼信息给UE(to transmit paging information to a UE)。
B)用于为了通知UE所述第一小区的第一***消息有更新(to inform UEs about a system information change)。
C)用于为了通知UE有关地震海啸***ETWS第一通知和/或ETWS第二通知(to inform about an ETWS primary notification and/or ETWS secondary notification)。
D)用于为了告知UE CMAS通知(to inform about a CMAS notification)。
具体地，本发明推荐，所述寻呼消息是要用于传输寻呼信息给UE(to  transmit paging information to a UE),可选地，所述寻呼消息还可以用于其他3种(B/C/D项)中的一种或者多种。当然除了上述4种之外，UE在第一小区接收的寻呼消息还可以用于其他用途，本发明不做过多限制。
第二，“所述UE在所述第一小区接收寻呼消息，并且所述UE在所述第二小区接收寻呼消息，所述UE在所述第二小区接收所述寻呼消息包括以下至少一种：用于通知所述第二小区的第二***消息更新的寻呼消息；用于通知有关地震海啸***ETWS第一通知和/或ETWS第二通知的寻呼消息；用于告知商用移动警报服务CMAS通知的寻呼消息。”可以是：UE在所述第一小区接收寻呼消息(可以是UE selects and monitors the indicated paging channels of the cell)，所述寻呼消息是用于以下的至少一种：
A)用于传输寻呼信息给UE(to transmit paging information to a UE)。
B)用于通知UE所述第一小区的第一***消息有更新(to inform UEs about a system information change)。
C)用于通知UE有关地震海啸***ETWS第一通知和/或ETWS第二通知(to inform about an ETWS primary notification and/or ETWS secondary notification)。
D)用于告知UE CMAS通知(Commercial Mobile Alert Service，CMAS)。
具体地，本发明推荐，所述寻呼消息是用于传输寻呼信息给UE(to transmit paging information to a UE)，可选地，所述寻呼消息还可以用于其他3种(B/C/D项)中的一种或者多种。当然除了上述4种之外，UE在第一小区接收的寻呼消息还可以用于其他用途，本发明不做过多限制。
另外在上述的基础上，在第二小区，所述UE可以在所述第二小区接收寻呼消息，所述UE在所述第二小区接收所述寻呼消息包括以下至少一种：用于通知所述第二小区的第二***消息更新的寻呼消息；用于通知有关地震海啸***ETWS第一通知和/或ETWS第二通知的寻呼消息；用于告知商用移动警报服务CMAS通知的寻呼消息。
上述4种(ABCD中的一种或者多种)可以在同一个寻呼消息中实现，也可以在多个寻呼消息中实现，本发明不限制具体的寻呼消息中包含的具体内容，只是说明UE在第二小区接收到的寻呼消息，所述寻呼消息可以是哪些用途或者是用于哪些目的的寻呼消息。本段内容还可以适用于其他实施例， 不一一重复。
本发明中，第一小区是第一节点的小区，第二小区是第二节点的小区。第一节点可以是宏基站，例如Macro eNB；第二节点可以是微基站，例如Pico eNB，HeNB，Small Cell eNB，Relay Station等等。当然在本发明中节点可以是各种类型的基站和节点，例如，Macro eNB，Micro eNB，Pico eNB，HeNB，Small Cell eNB，Relay Station等等，还有可能是移动管理实体MME等网络节点，在此不作限制。
S102：UE接收第一小区对应的第一节点发送的指示消息。
可选地，所述指示消息为所述第一小区的第一***消息，所述第一***消息包括候选小区的配置信息；其中，所述候选小区的配置信息包括以下至少一项：候选小区所属的***，候选小区所使用的频率，频率的优先级，物理小区标识(Physical Cell ID，PCI)，小区所属***优先级，不发送寻呼的标识，小区最低接入电平值Qrxlevmin，最小接入电平值的偏移值Qrxlevminoffset，门限的补偿量Pcompensation，UE所测量的小区所接收功率Qqualmeas，小区最低要求质量电平值Qqualmin，小区最低要求质量电平值的偏移值Qqualminoffset，时间Treselection，控制排序滞后度的参数QHyst，具有同等优先级频率时，服务小区和邻居小区之间使用的偏移量Qoffset，候选小区的标识；和/或者，所述第一***消息包括发送寻呼标识，所述发送寻呼标识用于指示所述第一小区可以发送寻呼消息给所述UE。
例如对于某个***(例如***EUTRA中)，提供了maxFreq个频率或者是maxFreq个小区所使用的频率，以下以频率来举例说明，针对每个频率carrierFreq，有对应的小区重选优先级cell Reselection Priority。每个频率对应的小区的物理小区标识PCI。另外还可以把不发送寻呼消息的小区作为一类，提供该类小区的配置(所述配置如本步骤S102中配置信息所示)给UE，因此这一类小区可以在消息中有一个不发送寻呼的标识，例如no_paging_cell(s)等，本发明不做限定。由此UE可以在这类小区中选择和确定一个合适的小区即第二小区。
FreqPriorityListEUTRA::＝SEQUENCE(SIZE(1..maxFreq))OF FreqPriorityEUTRA；
FreqPriorityEUTRA::＝SEQUENCE{
carrierFreq ARFCN-ValueEUTRA,
cellReselectionPriority CellReselectionPriority
配置消息中可以提供多个***的候选小区的配置信息，例如GERAN，EUTRA，UTRA-FDD，UTRA-FDD等多个***，在此不一一举例说明。
配置信息还提供了进行小区选择或者小区重选的配置，例如小区选择中所使用的S准则或R准则中所需要的参数。小区选择的S准则，具体内容包括：
Srxlev>0 AND Squal>0；
其中1)Srxlev＝Qrxlevmeas–(Qrxlevmin+Qrxlevminoffset)–Pcompensation；
Srxlev即小区选择接收电平值，Qrxlevmeas即UE所测量的小区所接收功率。消息中提供的参数：小区最低接入电平Qrxlevmin，最小接入电平值的偏移值Qrxlevminoffset，门限的补偿量Pcompensation。因此根据上述等式，消息中配置的参数，和rxlevmeas即UE所测量的小区所接收功率，就可以计算Srxlev是否大于0。
其中2)Squal＝Qqualmeas–(Qqualmin+Qqualminoffset)；
同理可以计算出Squal。

同频和同优先级的异频小区重选准则(Intra-frequency and equal priority inter-frequency Cell Reselection criteria)，也叫R准则，具体内容包括：为服务小区和邻居小区分别产生排序值Rs和Rn。只要在Treselection时间内比邻居小区比服务小区的排名高，UE就会重新选择高排序的候选小区。
RS＝Qmean,s+QHyst；
Rn＝Qmean,n+Qoffset；

所述指示消息可以是所述第一小区的第一***消息，也可以是其他消息，本发明不做限制。
S103：UE根据指示消息确定第二小区。
具体地，所述指示消息为所述第一小区的第一***消息，所述第一***消息包括候选小区的配置信息；则所述UE根据所述第一***消息确定第二小区，具体包括：所述UE根据所述候选小区的配置信息确定第二小区。例如：候选小区的配置信息包括候选小区所使用的频率，频率的优先级，则UE测量候选小区所使用的频率，根据测量结果确定候选小区的信号质量，然后，UE根据信号质量和/或频率的优先级确定第二小区。这里候选小区是小区的集合，假设两个小区的频率的优先级相同，则UE可以根据确定信号质量更好的一个小区为第二小区，其中这里的信号质量例如可以为信道状态指示参考信号(Channel State Indication RS,CSI-RS)质量、小区参考信号(cell reference signal，CRS)质量或者发现信号(Discovery Signal，DS)质量等。
可选地，所述确定第二小区包括：所述UE侦听所述候选小区的***消息，用于确定所述候选小区为第二小区，其中所述候选小区的***消息中包含不发送寻呼的标识。
第二小区的第二***消息中包含不发送寻呼的标识，所述不发送寻呼的标识用于指示第二节点不发送寻呼消息，或者用于指示所述第二节点仅在所述第二小区发送以下至少一项的寻呼消息：用于通知所述第二小区的第二***消息更新的寻呼消息；用于通知有关地震海啸***ETWS第一通知和/或ETWS第二通知的寻呼消息；用于告知商用移动警报服务CMAS通知的寻呼 消息。
同理，上述关于不发送寻呼的标识的内容也适用于其他小区(例如第二小区以外的其他小区，例如第三小区，第四小区)，其中所述其他小区的***消息包含不发送寻呼的标识。只需要把上述内容中的第二小区改成其他小区的名字即可。
同理，实施例中如在候选小区的配置信息中也包括了不发送寻呼的标识，上述关于不发送寻呼的标识相关内容也适用于候选小区，例如表示在该候选小区的UE在接收寻呼消息的两种可能或者该候选小区发送寻呼消息的两种可能。在此不重复描述。
本发明中所有实施例中“不发送寻呼的标识”还可以是其他名字，例如第二标识，本发明不做限制。
可选地，UE驻留在第一小区，接收第一小区的第一***消息，其中所述第一小区的第一***消息中还可以包含：发送寻呼标识。该发送寻呼标识还可以是其他名字，例如第一标识，本发明不做限制。所述发送寻呼标识可以表示4种可能：
A)用于传输寻呼信息给UE(to transmit paging information to a UE)。
B)用于通知UE所述第一小区的第一***消息有更新(to inform UEs about a system information change)。
C)用于通知UE有关地震海啸***ETWS第一通知和/或ETWS第二通知(to inform about an ETWS primary notification and/or ETWS secondary notification)。
D)用于告知UE CMAS通知(Commercial Mobile Alert Service，CMAS)。
进一步地，所述UE，仅从所述第一小区，接收寻呼消息；或者所述UE在所述第一小区接收寻呼消息，并且所述UE在所述第二小区接收寻呼消息，所述UE在所述第二小区接收以下至少一项的寻呼消息所述UE在所述第二小区接收所述寻呼消息包括以下至少一种：用于通知所述第二小区的第二***消息更新的寻呼消息；用于通知有关地震海啸***ETWS第一通知和/或ETWS第二通知的寻呼消息；用于告知商用移动警报服务CMAS通知的寻呼消息。
第一，“所述UE，仅从所述第一小区，接收寻呼消息”可以理解为：对 于第一小区(或者UE在第一小区执行第一小区重选时，重选确定后的新第一小区)和第二小区(或者UE在第二小区执行第二小区重选时，重选确定后的新第二小区)，UE只从所述第一小区(或者UE在第一小区执行第一小区重选时，重选确定后的新第一小区)接收寻呼消息，不从所述第二小区(或者UE在第二小区执行第二小区重选时，重选确定后的新第二小区)接收任何寻呼消息。其中UE在所述第一小区接收寻呼消息(可以是UE selects and monitors the indicated paging channels of the cell)，所述寻呼消息是用于以下的至少一种：
A)用于为了传输寻呼信息给UE(to transmit paging information to a UE)。
B)用于为了通知UE所述第一小区的第一***消息有更新(to inform UEs about a system information change)。
C)用于为了通知UE有关地震海啸***ETWS第一通知和/或ETWS第二通知(to inform about an ETWS primary notification and/or ETWS secondary notification)。
D)用于告知UE CMAS通知(Commercial Mobile Alert Service，CMAS)。
具体地，本发明推荐，所述寻呼消息是要用于传输寻呼信息给UE(to transmit paging information to a UE)，可选地，所述寻呼消息还可以用于其他3种(B/C/D项)中的一种或者多种。当然除了上述4种之外，UE在第一小区接收的寻呼消息还可以用于其他用途，本发明不做过多限制。
第二，关于“所述UE在所述第一小区接收寻呼消息，并且所述UE在所述第二小区接收寻呼消息，所述UE在所述第二小区接收所述寻呼消息包括以下至少一种：用于通知所述第二小区的第二***消息更新的寻呼消息；用于通知有关地震海啸***ETWS第一通知和/或ETWS第二通知的寻呼消息；用于告知商用移动警报服务CMAS通知的寻呼消息。”可以是：“UE在所述第一小区接收寻呼消息”(可以是UE selects and monitors the indicated paging channels of the cell)，在所述第一小区的所述寻呼消息是用于以下的至少一种：
A)用于传输寻呼信息给UE(to transmit paging information to a UE)。
B)用于通知UE所述第一小区的第一***消息有更新(to inform UEs about a system information change)。
C)用于通知UE有关地震海啸***ETWS第一通知和/或ETWS第二通知(to inform about an ETWS primary notification and/or ETWS secondary notification)。
D)用于告知UE CMAS通知(Commercial Mobile Alert Service，CMAS)。
具体地，本发明推荐，所述寻呼消息是用于传输寻呼信息给UE(to transmit paging information to a UE)，可选地，所述寻呼消息还可以用于其他3种(B/C/D项)中的一种或者多种。当然除了上述4种之外，UE在第一小区接收的寻呼消息还可以用于其他用途，本发明不做过多限制。
另外在上述的基础上，在第二小区，所述UE可以在所述第二小区接收寻呼消息，所述UE在所述第二小区接收所述寻呼消息包括以下至少一种：用于通知所述第二小区的第二***消息更新的寻呼消息；用于通知有关地震海啸***ETWS第一通知和/或ETWS第二通知的寻呼消息；用于告知商用移动警报服务CMAS通知的寻呼消息。
上述4种(ABCD中的一种或者多种)可以在同一个寻呼消息中实现，也可以在多个寻呼消息中实现，本发明不限制具体的寻呼消息中包含的具体内容，只是说明UE在第二小区接收到的寻呼消息，所述寻呼消息可以是哪些用途或者是用于哪些目的的寻呼消息。本段内容还可以适用于其他实施例，不一一重复。
关于如何确定第二小区，也可以沿用现有技术的小区重选的方法，本发明中确定的第二小区，该UE不会在该第二小区接收第一种情况的寻呼消息。例如，UE确定第二小区后在第二小区中所做的行为与UE驻留在第一小区的行为不同在于，UE在第二小区不接收第一种寻呼消息，或者是第二小区不会为UE发送第一种寻呼消息。当然有其他行为与驻留在一个小区不一样，本发明不做限制。
关于如何确定第二小区，UE可以在选择了一个信号比较好满足条件的小区作为第二小区之前，例如在候选小区中通过测量和比较，获得了一个或多个信号比较好满足选择条件的小区(例如小区A)，先去侦听一下该小区A的***消息，如果小区A***消息中包含了不发送寻呼消息的指示(不发送寻呼的标识)，那么UE就确认该小区是一个不发送寻呼消息的小区，因此选择该小区作为第二小区。所述小区A的***消息，也就是我们后来说的第 二小区的第二***消息。
UE在第二小区不接收寻呼消息，或者是第二小区不会为UE发送寻呼消息有两种含义从第二小区的角度，关于第二小区不发送寻呼消息，有两种可能：
1)第二小区不发送任何的寻呼消息给UE。
2)所述UE在所述第二小区接收所述寻呼消息包括以下至少一种：用于通知所述第二小区的第二***消息更新的寻呼消息；用于通知有关地震海啸***ETWS第一通知和/或ETWS第二通知的寻呼消息；用于告知商用移动警报服务CMAS通知的寻呼消息。
相应地，从UE的角度，UE在第二小区不接收寻呼消息，具体有两种可能：
1)UE在第二小区不接收任何的寻呼消息。
2)UE在第二小区只接收以下至少一项：用于通知所述第二小区的第二***消息更新的寻呼消息；用于通知有关地震海啸***ETWS第一通知和/或ETWS第二通知的寻呼消息；用于告知商用移动警报服务CMAS通知的寻呼消息。
可选地，UE在确定一个小区作为第二小区之前，可以侦听该小区的***消息，例如可以从该小区的***消息中获得一个不发送寻呼的标识，所述不发送寻呼的标识用于指示该小区是不发送寻呼消息的小区，那么UE可以判断该小区可以选择为UE的第二小区。具体地，可以是UE在多个候选小区进行测量和比较后，在选定高质量小区后，可以侦听该高质量小区的***消息后，确定该高质量小区为第二小区。当然UE还可以从第一小区发送的指示消息中获得不发送寻呼消息的小区或者小区集合(例如通过指示消息中提供的这种此类不发送寻呼消息的小区信息)，由此通过测量这些小区，确定一个小区(例如高质量的小区)是第二小区。在此关于如何确定一个小区是第二小区，本发明不做限制。此类不发送寻呼消息的小区不发送寻呼消息就如同关于第二小区不发送寻呼消息，有两种可能：
1)该小区不发送任何的寻呼消息给UE。
2)所述UE在该小区接收以下至少一项的寻呼消息：用于通知该小区的***消息更新的寻呼消息；用于通知有关地震海啸***ETWS第一通知和/ 或ETWS第二通知的寻呼消息；用于告知商用移动警报服务CMAS通知的寻呼消息。
可选地，UE在确定一个小区作为第二小区之前，可以侦听该小区的***消息，UE还可以从该***消息中获得该小区所属的TA标识，所述TA标识用于指示该小区所属的TA区域。如果该小区的TA标识与第一小区的TA标识相同，那么意味这这个小区与第一小区是同一个TA区域内。如果该小区的TA标识与第一小区的TA标识不相同，那么意味这这个小区与第一小区不在同一个TA区域内。当然如何分辨第一小区和第二小区是否在同一个TA内，可以使用不同的方法，本发明不做限制。第一小区的TA和第二小区的TA是否一致，本发明不做限制。
S104：UE接收第二小区的第二***消息，并对第二小区进行测量。
注意：本发明所有实施例中UE接收第二小区的第二***消息，还可以是UE侦听第二小区的第二***消息。也就是说“接收”***消息还可以是“侦听”***消息，本发明不做具体的限制。
可选地，UE并对第二小区进行测量，具体包括：所述UE根据所述第一***消息或第二***消息，对所述第二小区进行测量，并根据测量结果进行第二小区的小区重选。其中，第一***消息或第二***消息可以包括第二小区的配置信息，UE根据第二小区的配置信息进行小区重选评估，从而确定是否进行小区重选。
进一步地，所述UE根据所述第一***消息或第二***消息，对所述第二小区进行测量，并根据测量结果进行第二小区的小区重选：具体包括：若所述UE测量所述第二小区的信号质量小于或者等于第一门限值，则所述UE还包括对所述第二小区的同频小区和/或对优先级低于所述第二小区的异频小区进行测量，以使所述UE进行第二小区的小区重选；或者，所述UE对优先级高于所述第二小区的异频小区进行测量，若所述优先级高于所述第二小区的异频小区信号质量大于或者等于第二门限值，则所述UE进行第二小区的小区重选。
在确定第二小区之后：UE在第二小区(例如小区X)中，可以接收第二小区的第二***消息，对第二小区进行测量。UE在第二小区中，当第二小区信号质量下降时，还可以执行小区重选，让UE找到在一个信号更好，更合 适的第二小区(例如小区Y)，小区Y类似小区X，即UE重选到小区Y后，UE在小区Y不接收寻呼消息，或者是小区Y不会为UE发送寻呼消息。举例说明，小区Y类似小区X，UE确定小区Y后在小区Y中所做的行为与UE驻留在一个第一小区的行为不同在于，UE在小区Y不接收寻呼消息，或者是小区Y不会为UE发送寻呼消息。
可选地，上述S101-S104中的第一小区和第二小区可以为同一个跟踪区域内的小区。当然也可以是不一样的，本发明不做限制。
可选地，所述UE根据所述指示消息在确定第二小区的过程中或者确定第二小区之后，所述UE依旧驻留在所述第一小区；或者，所述UE在确定第二小区的过程中或者之后，所述UE进行第一小区的小区重选。也就是说，UE可以并行做两件事情，第一个事情是UE驻留在第一小区，现有技术中UE只是驻留在一个小区，本发明都可以继续使用。例如UE选择了一个合适的小区驻留，UE在该小区：根据该小区发送的***消息来获得各种配置信息，例如寻呼消息配置，以便于能够在寻呼信道中监听和接收网络(例如公共陆地移动网络(Public Land Mobile Network，PLMN))发送的寻呼消息；还有通过侦听该小区的***消息，还可以获得例如接入配置，寻呼配置，小区选择/重选配置，TA信息等。还可以获得例如接收接入层和非接入层信息等。举例说明***消息具体可以包括以下配置但不限于以下配置：
MIB:DL BW,PHICH configuration,SFN；
SIB1:PLMN ID,Cell Global ID,Cell barred status,cell selection information,CSG indication,scheduling information,valuetag；
SIB2:ACB information,radioresourceconfigurationcomm,UL BW；
SIB3:cell reselection information(serving cell information,speed scale information)。
执行测量以便于进行小区重选评估流程。(注意：如果本小区信号质量不好，就有可能重选到其他小区。另外如果其他小区和该小区是不是同一个TA，那么UE就会启动TA更新流程，以便于让MME知道该UE到了其他TA区域中。)当在该小区收到寻呼该UE的消息时，该UE在该小区发起随机接入，建立无线资源控制RRC连接。
第二件事情，即UE确定一个第二小区，在第二小区中接收第二小区的 第二***消息，对第二小区进行测量。UE确定一个第二小区后，可以进行小区重选。另外，具体地，例如，UE确定第二小区后在第二小区中所做的行为与UE驻留在一个小区的行为不同在于，例如UE在第二小区不接收寻呼消息，或者是第二小区不会为UE发送寻呼消息。UE可以在第二小区不执行TA更新，TA更新只在第一小区中执行。UE可以不在该小区中建立RRC连接也可以在该小区建立RRC连接。UE可以在第二小区接收ETWS通知(第一ETWS通知和/或第二ETWS通知)和CMAS通知，当然也可以是UE不在第二小区接收ETWS通知和CMAS通知而是在第一小区接收，本发明不做限制。
总之保证空闲态的UE总能驻留在一个小区(例如第一小区，或者在第一小区进行小区重选后确定的新第一小区)的同时，还在另一个小区(例如第二小区，或者在第二小区进行小区重选后确定的新第二小区)中接收该小区的***消息，进行测量，进行小区重选等。需要强调的是，对于接收寻呼消息而言，对于第一小区(或者UE在第一小区执行第一小区重选时，重选确定后的新第一小区)和第二小区(或者UE在第二小区执行第二小区重选时，重选确定后的新第二小区)，第一种可能，“所述UE，仅从所述第一小区，接收寻呼消息”，或者第二种可能是“所述UE在所述第一小区接收寻呼消息，并且所述UE在所述第二小区接收寻呼消息，所述UE在所述第二小区接收所述寻呼消息包括以下至少一种：用于通知所述第二小区的第二***消息更新的寻呼消息；用于通知有关地震海啸***ETWS第一通知和/或ETWS第二通知的寻呼消息；用于告知商用移动警报服务CMAS通知的寻呼消息。
其中，第一种可能，“所述UE，仅从所述第一小区，接收寻呼消息”可以理解为：对于第一小区(或者UE在第一小区执行第一小区重选时，重选确定后的新第一小区)和第二小区(或者UE在第二小区执行第二小区重选时，重选确定后的新第二小区)，UE只从所述第一小区(或者UE在第一小区执行第一小区重选时，重选确定后的新第一小区)接收寻呼消息，不从所述第二小区(或者UE在第二小区执行第二小区重选时，重选确定后的新第二小区)接收任何寻呼消息。其中UE在所述第一小区接收寻呼消息(可以是UE selects and monitors the indicated paging channels of the cell)，所述寻呼消息是用于以下的至少一种：
A)用于为了传输寻呼信息给UE(to transmit paging information to a UE)。
B)用于为了通知UE所述第一小区的第一***消息有更新(to inform UEs about a system information change)。
C)用于为了通知UE有关地震海啸***ETWS第一通知和/或ETWS第二通知(to inform about an ETWS primary notification and/or ETWS secondary notification)。
D)用于告知UE CMAS通知(Commercial Mobile Alert Service，CMAS)。
具体地，本发明推荐，所述寻呼消息是要用于传输寻呼信息给UE(to transmit paging information to a UE)，可选地，所述寻呼消息还可以用于其他3种(B/C/D项)中的一种或者多种。当然除了上述4种之外，UE在第一小区接收的寻呼消息还可以用于其他用途，本发明不做过多限制。
第二，关于“所述UE在所述第一小区接收寻呼消息，并且所述UE在所述第二小区接收寻呼消息，所述UE在所述第二小区接收所述寻呼消息包括以下至少一种：用于通知所述第二小区的第二***消息更新的寻呼消息；用于通知有关地震海啸***ETWS第一通知和/或ETWS第二通知的寻呼消息；用于告知商用移动警报服务CMAS通知的寻呼消息。”可以是：“UE在所述第一小区接收寻呼消息”(可以是UE selects and monitors the indicated paging channels of the cell)，在所述第一小区的所述寻呼消息是用于以下的至少一种：
A)用于传输寻呼信息给UE(to transmit paging information to a UE)。
B)用于通知UE所述第一小区的第一***消息有更新(to inform UEs about a system information change)。
C)用于通知UE有关地震海啸***ETWS第一通知和/或ETWS第二通知(to inform about an ETWS primary notification and/or ETWS secondary notification)。
D)用于告知UE CMAS通知(Commercial Mobile Alert Service，CMAS)。
具体地，本发明推荐，所述寻呼消息是用于传输寻呼信息给UE(to transmit paging information to a UE)，可选地，所述寻呼消息还可以用于其他3种(B/C/D项)中的一种或者多种。当然除了上述4种之外，UE在第一小区接收的寻呼消息还可以用于其他用途，本发明不做过多限制。上述4 种(ABCD中的一种或者多种)可以在同一个寻呼消息中实现，也可以在多个寻呼消息中实现，本发明不限制具体的寻呼消息中包含的具体内容，只是说明UE在第二小区接收到的寻呼消息，所述寻呼消息可以是哪些用途或者是用于哪些目的的寻呼消息。本段内容还可以适用于其他实施例，不一一重复。
另外在上述的基础上，在第二小区，所述UE可以在所述第二小区接收寻呼消息，所述UE在所述第二小区接收所述寻呼消息包括以下至少一种：用于通知所述第二小区的第二***消息更新的寻呼消息；用于通知有关地震海啸***ETWS第一通知和/或ETWS第二通知的寻呼消息；用于告知商用移动警报服务CMAS通知的寻呼消息。上述3种中1一种或者多种可以在同一个寻呼消息中实现，也可以在多个寻呼消息中实现，本发明不限制具体的寻呼消息中包含的具体内容，只是说明UE在第二小区接收到的寻呼消息，所述寻呼消息可以是哪些用途或者是用于哪些目的的寻呼消息。本段内容还可以适用于其他实施例，不一一重复。
也就是说，UE在第二小区，可以不接收任何寻呼消息，还可以在第二小区接收有限的所述一种或者多种用途的寻呼消息。例如UE在第二小区只是接收用于通知所述第二小区的第二***消息更新的寻呼消息，而在第一小区UE接收用于传输寻呼信息的寻呼消息和用于通知第一小区第一***消息更新的寻呼消息；可选地，UE还可以在第一小区接收其他用途寻呼消息。
总之，也就是说，UE在第二小区，可以不接收任何寻呼消息，还可以在第二小区接收有限的所述一种或者多种用途的的寻呼消息。例如UE在第二小区只是接收用于通知所述第二小区的第二***消息更新的寻呼消息，而其他的寻呼消息可以在第一小区接收，例如在第一小区接收寻呼消息用于上述ABCD项中的一种或者多种。
因此，对于UE在第二小区的行为，具体地，例如，UE确定第二小区后在第二小区中所做的行为与UE驻留在一个小区的行为不同可以是在于，UE在第二小区不接收寻呼消息或者只接收用于某一种/几种类型目的的寻呼消息(如上述)。当然UE在第二小区所做的行为还有可能与驻留在第一小区的行为有所不同，本发明不做过多限制。UE在第一小区可以进行小区重选，确定一个新的第一小区驻留，另外UE在第二小区也可以进行小区重选，确 定一个新的第二小区。由此以此类推，总能保证UE驻留在一个小区，同时在另外一个小区接收该小区的***消息，测量等，但对于接收寻呼消息而言，在两个小区中UE行为有所不同。
进一步地，若UE在第一小区接收到寻呼消息，则UE在第二小区发起随机接入和/或在第二小区建立RRC连接；和/或，若UE在第一小区接收到寻呼消息，则UE在第一小区发起随机接入和/或在第一小区建立无线资源控制RRC连接。还可以是，若UE在第一小区接收到寻呼消息，则UE将第二小区的信息发送给第一节点，从而使得第一节点根据第二小区的信息确定为UE提供双连接服务的辅节点；或者，第一节点根据第二小区的信息发送请求消息给第二节点，请求消息用于请求第二节点作为UE的双连接的辅节点。从而使得两个小区对应节点都同时可以为UE服务。这种情况，可以是UE与第一小区进行随机接入或者是建立RRC连接的过程中，UE把第二小区的信息提供给第一节点。其中，第二小区的信息包括以下至少一项：第二小区的小区全局标识(E-UTRAN Cell Global Identifier，ECGI)，第二小区的物理小区标识PCI和第二小区对应的第二节点标识ENB ID。
可选地，所述UE接收所述第二小区的第二***消息，并对所述第二小区进行测量后，所述UE记录所述第二小区的信息，依旧驻留在所述第一小区。
本实施例提供了一种确定小区的方法，包括：UE驻留在第一小区，UE接收第一节点发送的寻呼消息，并根据寻呼消息确定第二小区，然后，UE接收第二小区的第二***消息，并对第二小区进行测量，其中由于UE仅从第一小区接收寻呼消息，但是通常第二小区的信号质量比较好，因此，本实施例提供了确定第二小区的方法，使得UE仅在第一小区接收寻呼消息，从而降低资源消耗和网络负荷，并且第一小区和/或第二小区对应节点可以为UE实现数据业务的传输，进而提高传输数据业务的效率。
图2为本发明实施例二提供的一种确定小区的方法的流程图，该方法可适用于第一节点确定传输数据业务的小区的场景，其中该方法的执行主体为第一节点，该方法的具体流程包括：

S803：UE驻留在第一小区。
S804：UE接收第二小区的第二***消息，并对第二小区进行测量。
具体地，所述并对所述第二小区进行测量，具体包括：所述UE根据所述第一小区的第一***消息或所述第二小区的第二***消息，对所述第二小区进行测量，并根据测量结果进行第二小区的小区重选。所述UE根据所述第一小区的第一***消息或所述第二小区的第二***消息，对所述第二小区进行测量，并根据测量结果进行第二小区的小区重选：具体包括：若所述UE测量所述第二小区的信号质量小于或者等于第一门限值，则所述UE还包括对所述第二小区的同频小区和/或对优先级低于所述第二小区的异频小区进行测量，以使所述UE进行第二小区的小区重选；或者，所述UE对优先级高于所述第二小区的异频小区进行测量，若所述优先级高于所述第二小区的异频小区信号质量大于或者等于第二门限值，则所述UE进行第二小区的小区重选。
进一步地，若所述UE在所述第一小区接收到寻呼消息，则所述UE在所述第二小区发起随机接入和/或在所述第二小区建立无线资源控制RRC连接；和/或，若所述UE在所述第一小区接收到寻呼消息，则所述UE在所述第一小区发起随机接入和/或在所述第一小区建立无线资源控制RRC连接。
可选地，若所述UE在所述第一小区接收到寻呼消息，则所述UE将所述第二小区的信息发送给所述第一节点。其中，所述第二小区的信息包括以下至少一项：所述第二小区的小区全局标识ECGI、所述第二小区的物理小区标识PCI和所述第二小区对应的第二节点标识ENB ID。上述步骤中所述第一小区和第二小区为同一个跟踪区域内的小区。
可选地，所述UE接收所述第二小区的第二***消息，并对所述第二小区进行测量后，所述UE记录所述第二小区的信息，依旧驻留在所述第一小区。
具体地，例如通过上述实施内容，可以保证UE总能驻留在一个小区(例如第一小区，或者在第一小区进行小区重选后确定的新第一小区)，同时，还在另一个小区(例如第二小区，或者在第二小区进行小区重选后确定的新第二小区)中接收该小区的***消息，进行测量，进行小区重选等。需要强调的是，同时，还在另一个小区(例如第二小区，或者在第二小区进行小区重选后确定的新第二小区)中接收该小区的***消息，进行测量，进行小区重选等。需要强调的是，对于接收寻呼消息而言，对于第一小区(或者UE在第一小区执行第一小区重选时，重选确定后的新第一小区)和第二小区(或者UE在第二小区执行第二小区重选时，重选确定后的新第二小区)，第一种可能，“所述UE，仅从所述第一小区，接收寻呼消息”，或者第二种可能是“所述UE在所述第一小区接收寻呼消息，并且所述UE在所述第二小区接收寻呼消息，所述UE在所述第二小区接收所述寻呼消息包括以下至少一种：用于通知所述第二小区的第二***消息更新的寻呼消息；用于通知有关地震海啸***ETWS第一通知和/或ETWS第二通知的寻呼消息；用于告知商用移动警报服务CMAS通知的寻呼消息。
其中，第一种可能，“所述UE，仅从所述第一小区，接收寻呼消息”可以理解为：对于第一小区(或者UE在第一小区执行第一小区重选时，重选确定后的新第一小区)和第二小区(或者UE在第二小区执行第二小区重选时，重选确定后的新第二小区)，UE只从所述第一小区(或者UE在第一小区执行第一小区重选时，重选确定后的新第一小区)接收寻呼消息，不从所述第二小区(或者UE在第二小区执行第二小区重选时，重选确定后的新第二小区)接收任何寻呼消息。其中UE在所述第一小区接收寻呼消息(可以 是UE selects and monitors the indicated paging channels of the cell)，所述寻呼消息是用于以下的至少一种：
A)用于为了传输寻呼信息给UE(to transmit paging information to a UE)。
B)用于为了通知UE所述第一小区的第一***消息有更新(to inform UEs about a system information change)。
C)用于为了通知UE有关地震海啸***ETWS第一通知和/或ETWS第二通知(to inform about an ETWS primary notification and/or ETWS secondary notification)。
D)用于告知UE CMAS通知。
具体地，本发明推荐，所述寻呼消息是要用于传输寻呼信息给UE(to transmit paging information to a UE)，可选地，所述寻呼消息还可以用于其他3种(B/C/D项)中的一种或者多种。当然除了上述4种之外，UE在第一小区接收的寻呼消息还可以用于其他用途，本发明不做过多限制。
第二，关于“所述UE在所述第一小区接收寻呼消息，并且所述UE在所述第二小区接收寻呼消息，所述UE在所述第二小区接收所述寻呼消息包括以下至少一种：用于通知所述第二小区的第二***消息更新的寻呼消息；用于通知有关地震海啸***ETWS第一通知和/或ETWS第二通知的寻呼消息；用于告知商用移动警报服务CMAS通知的寻呼消息。”可以是：“UE在所述第一小区接收寻呼消息”(可以是UE selects and monitors the indicated paging channels of the cell)，在所述第一小区的所述寻呼消息是用于以下的至少一种：
A)用于传输寻呼信息给UE(to transmit paging information to a UE)。
B)用于通知UE所述第一小区的第一***消息有更新(to inform UEs about a system information change)。
C)用于通知UE有关地震海啸***ETWS第一通知和/或ETWS第二通知(to inform about an ETWS primary notification and/or ETWS secondary notification)。
D)用于告知UE CMAS通知。
具体地，本发明推荐，所述寻呼消息是用于传输寻呼信息给UE(to transmit paging information to a UE)，可选地，所述寻呼消息还可以用于其他 3种(B/C/D项)中的一种或者多种。当然除了上述4种之外，UE在第一小区接收的寻呼消息还可以用于其他用途，本发明不做过多限制。上述4种(ABCD中的一种或者多种)可以在同一个寻呼消息中实现，也可以在多个寻呼消息中实现，本发明不限制具体的寻呼消息中包含的具体内容，只是说明UE在第二小区接收到的寻呼消息，所述寻呼消息可以是哪些用途或者是用于哪些目的的寻呼消息。本段内容还可以适用于其他实施例，不一一重复。
另外在上述的基础上，在第二小区，所述UE可以在所述第二小区接收寻呼消息，所述UE在所述第二小区接收所述寻呼消息包括以下至少一种：用于通知所述第二小区的第二***消息更新的寻呼消息；用于通知有关地震海啸***ETWS第一通知和/或ETWS第二通知的寻呼消息；用于告知商用移动警报服务CMAS通知的寻呼消息。上述3种中一种或者多种可以在同一个寻呼消息中实现，也可以在多个寻呼消息中实现，本发明不限制具体的寻呼消息中包含的具体内容，只是说明UE在第二小区接收到的寻呼消息，所述寻呼消息可以是哪些用途或者是用于哪些目的的寻呼消息。本段内容还可以适用于其他实施例，不一一重复。
也就是说，UE在第二小区，可以不接收任何寻呼消息，还可以在第二小区接收有限的所述1种或者多种用途的寻呼消息。例如UE在第二小区只是接收用于通知所述第二小区的第二***消息更新的寻呼消息，而在第一小区UE接收用于传输寻呼信息的寻呼消息和用于通知第一小区第一***消息更新的寻呼消息；可选地，UE还可以在第一小区接收其他用途寻呼消息。
总之，也就是说，UE在第二小区，可以不接收任何寻呼消息，还可以在第二小区接收有限的所述一种或者多种用途的的寻呼消息。例如UE在第二小区只是接收用于通知所述第二小区的第二***消息更新的寻呼消息，而其他的寻呼消息可以在第一小区接收，例如在第一小区接收寻呼消息用于上述ABCD项中的一种或者多种。
因此，对于UE在第二小区的行为，具体地，例如，UE确定第二小区后在第二小区中所做的行为与UE驻留在一个小区的行为不同可以是在于，UE在第二小区不接收寻呼消息或者只接收用于某一种/几种类型目的的寻呼消息(如上述)。当然UE在第二小区所做的行为还有可能与驻留在第一小区的行为有所不同，本发明不做过多限制。UE在第一小区可以进行小区重选， 确定一个新的第一小区驻留，另外UE在第二小区也可以进行小区重选，确定一个新的第二小区。由此以此类推，总能保证UE驻留在一个小区，同时在另外一个小区接收该小区的***消息，测量等，但对于接收寻呼消息而言，在两个小区中UE行为有所不同。
本实施例提供了一种确定小区的方法，包括：首先，UE接收第二小区对应的第二节点发送的第二***消息；然后，UE根据第二***消息确定第一小区；UE接收第二小区的第二***消息，并对第二小区进行测量；从而降低资源消耗和网络负荷，并且UE可以通过第一小区和/或第二小区对应节点为它进行数据业务的传输，进而提高传输数据业务的效率。

S901：第一节点是发送第一***消息和寻呼消息给UE的节点。
S902：第一节点向UE发送第一***消息。
具体地，所述第一***消息包括候选小区的配置信息；所述候选小区的配置信息包括以下至少一项：候选小区所属的***，候选小区所使用的频率，频率的优先级，物理小区标识PCI，小区所属***优先级，不发送寻呼的标识，小区最低接入电平值Qrxlevmin，最小接入电平值的偏移值Qrxlevminoffset，门限的补偿量Pcompensation，UE所测量的小区所接收功率Qqualmeas，小区最低要求质量电平值Qqualmin，小区最低要求质量电平值的偏移值Qqualminoffset，时间Treselection，控制排序滞后度的参数QHyst，具有同等优先级频率时，服务小区和邻居小区之间使用的偏移量Qoffset，候选小区的标识；和/或者所述第一***消息包括发送寻呼标识，所述发送寻呼标识用于指示所述第一小区可以发送寻呼消息给所述UE。

同理，上述关于不发送寻呼的标识的内容也适用于其他小区(例如第二小区以外的其他小区，例如第三小区，第四小区)，其中所述其他小区的***消息包含不发送寻呼标识。只需要把上述内容中的第二小区改成其他小区的名字即可。
同理，实施例中如在候选小区的配置信息中也包括了不发送寻呼的标识， 上述关于不发送寻呼的标识相关内容也适用于候选小区，例如表示在该候选小区的UE在接收寻呼消息的两种可能或者该候选小区发送寻呼消息的两种可能。在此不重复描述。
