Description

通信方法及装置
本申请要求在2017年6月16日提交中华人民共和国知识产权局、申请号为201710459436.0、发明名称为“通信方法及装置”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，特别涉及一种通信方法及装置。
背景技术
为了应对越来越大的流量需求和各种各样不同需求的业务，第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)标准组织当前正在制定下一代移动通信系统。在当前的讨论中，引入一种新的无线资源控制(Radio Resource Control，RRC)状态，即去活动态(Inactive state)。处于去活动态的用户设备(User Equipment，UE)与网络断开了RRC连接，不需要连续监听下行数据，从而达到与空闲态一样的省电效果，但处于去活动态的UE和接入网络设备均保存UE的上下文信息，当UE需要进入连接态时(比如，UE有上行数据需要发送，或者网络寻呼UE进入到连接态)，接入网设备可以基于保存的上下文信息配置去活动态UE进入到连接态，从而能够减少时延和节省信令开销。
然而，针对去活动态的UE，尚有较多流程需要优化或者明确。
发明内容
本申请提供一种通信方法，用于提供一种可以适用于存在去活动态终端的网络环境的方案。

如此，检测出去活动态的终端处于非服务状态后，确定终端的目标小区，从而使得终端能够重新回到网络，便于后续正常寻呼或找到终端。进一步地，当在第一时间长度的时间内没有确定出所述目标小区，终端进入空闲态，而无需继续保存终端的上下文信息，能够节省存储空间。
在一个可能的设计中，所述方法还包括：
向所述目标小区对应的接入网设备发送第一指示信息，所述第一指示信息用于指示所述终端在接入到所述目标小区之前处于非服务状态。
如此，终端重新回到网络后，可向目标小区对应的接入网设备上报其在接入目标小区之前处于非服务状态，也就是说通知了接入网设备其接入网络的原因。
在一个可能的设计中，所述向所述目标小区对应的接入网设备发送第一指示信息，包括：

根据所述无线网络区域的信息进行小区重选。
如此，终端在无线网络区域内移动时，可根据接收到的接入网设备发送的无线网络区域的信息进行小区重选，从而能够尽可能优选到无线网络区域内的小区，有效避免优先重选到无线网络区域之外的小区而造成较多的信令开销和延迟的问题。

在一个可能的设计中，所述根据所述无线网络区域的信息进行小区重选，包括：
根据所述无线网络区域的一个或多个小区的信号质量进行小区重选。
如此，终端获取无线网络区域内的一个或多个小区的信号质量后，可基于信号质量在无线网络区域内进行小区重选，从而能够优先重选到无线网络区域内的小区。
例如，根据信号质量，从一个或多个小区中选择出信号质量符合要求(信号质量大于预设的信号质量阈值)的小区，进而确定出符合要求的小区中信号质量最好的小区，并重选到该小区。或者，如果无线网络区域的信息中还包括一个或多个小区的重分布参数，则根据信号质量选择出信号质量符合要求的小区后，可根据重分布参数进行小区重选。
在一个可能的设计中，所述无线网络区域的信息还包括第一优先级信息，所述第一优先级信息包括所述无线网络区域包括的一个或者多个小区的优先级信息；
所述根据所述无线网络区域的信息进行小区重选，包括：
根据所述第一优先级信息进行小区重选。
如此，终端可根据一个或多个小区的优先级信息，选择出优先级最高的小区，并判断优先级最高的小区是否适合接入，若优先级最高的小区仅有一个且适合接入，则终端可重选到该小区。
若优先级最高的小区有两个或两个以上，则可根据信号质量，从优先级最高的小区中选择出一个信号质量最好的小区并重选到该小区；或者，如果第一优先级信息中还包括接入网设备为终端配置的一个或多个小区的重分布参数，则终端也可以根据无线网络区域内 的一个或多个小区的信号质量和重分布参数，从优先级最高的小区中确定出符合条件的小区，并重选到该小区。
若终端采用上述方式未能从优先级最高的小区中选择出合适的小区，则终端可排除优先级最高的小区，并从无线网络区域中剩下的小区中选择出优先级最高的小区，根据信号质量(和重分布参数)进行小区重选，若选择出合适的小区，则重选到该小区，若未能选择出合适的小区，则按照上述方式类推，直到选择出合适的小区。
在一个可能的设计中，所述方法还包括：
接收第二优先级信息，所述第二优先级信息包括至少一个小区的优先级信息；
所述根据所述无线网络区域的信息进行小区重选，包括：
根据所述和无线网络区域的信息和所述第二优先级信息。
如此，终端根据第二优先级信息，得到无线网络区域内的小区的优先级信息(此处，得到的可能是无线网络区域内的所有小区的优先级信息，也可能只是无线网络区域内的部分小区的优先级信息)，选择出优先级最高的小区，并判断优先级最高的小区是否适合接入，若优先级最高的小区仅有一个且适合接入，则终端可重选到该小区。
若优先级最高的小区由两个或两个以上，则可根据信号质量，从优先级最高的小区中选择出一个信号质量最好的小区并重选到该小区；或者，如果第二优先级信息中还包括至少一个小区的重分布参数，则终端根据第二优先级信息可得到无线网络区域内的小区的重分布参数，进而也可以根据无线网络区域内的小区的信号质量和重分布参数，从优先级最高的小区中确定出符合条件的小区，并重选到该小区。
在一个可能的设计中，接收第二优先级信息，所述第二优先级信息包括至少一个小区的优先级信息；
所述根据所述无线网络区域的信息进行小区重选，包括：
根据所述第一优先级信息和第二优先级信息，进行小区重选。
如此，可综合考虑第一优先级信息和第二优先级信息，来确定无线网络区域内的小区的优先级信息；进一步地，若第一优先级信息、第二优先级信息中均包括小区的重分布参数，则在确定出无线网络区域内的小区的优先级信息后，还可进一步得到小区的重分布参数。其中，若小区的优先级信息采用的是第一优先级信息中包括的该小区的优先级信息，则该小区的重分布参数也应采用第一优先级信息中包括的该小区的重分布参数。
采用上述方式确定出无线网络区域内的小区的优先级信息和重分布参数后，可根据小区的优先级、信号质量和重分布参数进行小区重选。
本申请还提供一种通信装置，该通信装置可以是终端，也可以是终端内部的芯片，该通信装置具有实现上述第七方面方法示例中的功能。所述功能可以通过硬件实现，也可以通过硬件执行相应的软件实现。所述硬件或所述软件包括一个或多个与上述功能相对应的模块。

此处，在无线网络区域内来寻呼终端后，若接收到终端反馈的寻呼响应消息，或者接收到无线网络区域内的其它接入网设备在收到终端的寻呼响应消息反馈的响应消息，可确定成功寻呼到终端。其中，其它接入网设备在收到终端的寻呼响应消息反馈的响应消息具体可以是：其它接入网设备在收到终端的寻呼响应消息反馈的请求获取终端的上下文的消息。
然而，也可能会出现一些异常情况，导致接入网设备侧未接收到终端反馈的寻呼响应消息，且，未接收到所述无线网络区域内的其它接入网设备在收到所述终端的寻呼响应消息反馈的响应消息，此种情况下，接入网设备侧可确定寻呼失败，并向核心网设备侧发送终端的无线网络区域的信息。
在一个可能的设计中，所述向所述核心网设备发送所述终端的无线网络区域的信息之后，还包括：
删除所述终端的上下文信息，其中，终端的上下文信息中包括所述无线网络区域的信息。

在一个可能的设计中，所述向所述核心网设备发送所述终端的无线网络区域的信息之后，还包括：
释放所述终端对应的接入网和核心网之间的网络连接。
如此，若确定寻呼失败，说明终端对应的接入网和核心网之间的网络连接可能已经无法使用，此时删除终端对应的接入网和核心网之间的网络连接，能够有效节省网络资源。

具体实施方式
下面结合说明书附图对本申请进行具体说明。
图1为本申请适用的一种系统架构示意图。如图1所示，该系统架构中包括核心网设备101、一个或多个接入网设备(比如图1所示的接入网设备1021、接入网设备1022、接入网设备1023)、一个或多个终端(比如图1所示的终端1031、终端1032、终端1033)。
本申请中，无线接入网设备可以为基站设备(base station，BS)。基站设备也可称为基站，是一种部署在无线接入网用以提供无线通信功能的装置。例如在5G网络中提供基站功能的设备包括以下一种或者多种：新无线节点B(New Radio NodeB，gNB)，集中单元(Centralized Unit，CU)，分布式单元(Distributed Unit)。
终端是一种具有无线收发功能的设备，可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端、增强现实(Augmented Reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。
接入网设备的覆盖区域可以划分为一个或多个小区，图1中简单示意出了接入网设备1021覆盖范围内的小区1、接入网设备1022覆盖范围内的小区2、接入网设备1023覆盖范围内的小区3。
以终端1032为例，终端1032接入小区2后，小区2对应的接入网设备1022可配置终端1032进入去活动态。本申请中，可将配置终端进入去活动态的接入网设备称为锚点(Anchor)接入网设备，例如，上述接入网络设备1022即为终端1032的Anchor接入网设备。本申请以下实施例中，将处于去活动态的终端简称为去活动态的终端。
可以理解的是，本申请实施例中的去活动态也可以称为第三态。
举例来说，接入网设备1022可通过专有信令向终端1032发送无线网络区域的信息，其中，无线网络区域可包括一个或多个小区，无线网络区域的信息包括用于标识一个或者多个小区的信息。用于标识小区的信息可以是以小区为粒度，也可以进一步携带小区的频率信息。
本申请实施例以小区为粒度的参数举例说明无线网络区域的信息。
例如，无线网络区域包括小区1、小区2，无线网络区域的信息包括小区1的标识和小区2的标识。
可以理解的是，本申请实施例中，小区的标识或小区标识可以包括以下至少一种：小区的全局小区标识(Global Cell Identity，GCI)、物理小区标识(Physical Cell Identity，PCI)、频率、同步信号(Synchronization Signal，SS)模式pattern和小区的beam信息。
本申请中，接入网设备1022向终端1032发送无线网络区域的信息的具体实现方式可能 有多种，例如1，接入网设备1022以小区列表的形式向终端1032发送无线网络区域的信息。如表1所示，为小区列表中的内容示意。
表1：小区列表中的内容示意
小区标识
小区1
小区2
如表1所示，小区列表中的小区即为无线网络区域包括的小区。实际应用中，可根据需要在表1的基础上增加其它内容。
例如2，接入网设备1022向终端1032发送无线网络区域的标识(设为无线网络区域1)，终端1032可根据无线网络区域的标识得到无线网络区域包括的一个或多个小区。此种情形下，每个小区可广播其所属的无线网络区域的标识，例如，小区1广播其所属的无线网络区域的标识为无线网络区域1，小区2广播其所属的无线网络区域的标识为无线网络区域1，小区3广播其所属的无线网络区域的标识为无线网络区域2。如此，终端1032可根据各个小区的广播，得到属于无线网络区域1的小区为小区1和小区2，进而确定出接入网络设备1022为其配置的无线网络区域包括的小区。
终端1032接收到无线网络区域的信息后，进入去活动态，此时，终端1032与接入网设备1022断开了RRC连接，但接入网设备1022和核心网设备101之间仍存在终端1032对应的网络连接。
由于接入网设备1022和核心网设备101之间仍存在终端1032对应的网络连接，因此，核心网设备101会直接把数据发给去活动态的终端1032最后连接的接入网设备1022。由于接入网设备1022不能确定终端1032是否在其覆盖范围内，因此，需要寻呼去活动态的UE时，接入网设备1022首先在无线网络区域(即小区1和小区2)进行寻呼，具体来说，接入网设备1022会触发无线接入网发起通知(RAN-initiated notification)，并发送给无线网络区域内的全部接入网设备，使得无线网络区域内的全部接入网设备发起RAN-initiated notification来寻呼终端1032。可选地，若在整个无线网络区域内都没有寻呼到终端1032，即没有收到终端1032的响应，接入网设备1022还可以和核心网设备101进行交互，使得核心网设备101发起寻呼(CN-initiated paging)，从而在更大的范围内(比如跟踪区(Tracking Area，TA)，或跟踪区列表TA list)寻呼终端1032。例如，终端1032的TA范围包括小区1、小区2和小区3，则核心网设备可在小区1、小区2和小区3内寻呼终端1032。
本申请一实施例提供一种方案，有效避免核心网设备在无线网络区域内重复寻呼所造成的信令开销。下面结合图2a对本申请实施例的方法进行具体说明，如图2a所示，提供了一种通信方法，包括：
步骤201，根据终端的无线网络区域的信息，在无线网络区域内寻呼终端；所述无线网络区域包括一个或多个小区，所述无线网络区域的信息包括用于标识所述一个或者多个小区的信息。
此处，对于去活动态的终端，由于终端对应的接入网和核心网之间的网络连接仍然存在，因此，核心网设备侧会将终端的下行数据发送给接入网设备侧，接入网设备侧可根据为终端配置的无线网络区域的信息，在无线网络区域内来寻呼终端。
需要说明的是，接入网设备侧触发寻呼的原因除接收到下行数据外，还可以是接入网设备侧自己主动触发的，比如接入网设备侧想要释放终端的上下文信息，或者要求终端上报位置信息等。
步骤202，若确定寻呼失败，向核心网设备发送所述终端的无线网络区域的信息。
此处，接入网设备侧在无线网络区域内来寻呼终端后，若接收到终端反馈的寻呼响应消息，或者接收到无线网络区域内的其它接入网设备在收到终端的寻呼响应消息反馈的响应消息，可确定成功寻呼到终端，并将接收到的下行数据发送给终端。其中，其它接入网设备在收到终端的寻呼响应消息反馈的响应消息具体可以是：其它接入网设备在收到终端的寻呼响应消息反馈的请求获取终端的上下文的消息。
然而，也可能会出现一些异常情况，导致接入网设备侧未接收到终端反馈的寻呼响应消息，且，未接收到所述无线网络区域内的其它接入网设备在收到所述终端的寻呼响应消息反馈的响应消息，此种情况下，接入网设备侧可确定寻呼失败，并向核心网设备侧发送终端的无线网络区域的信息。
进一步地，接入网设备侧还可删除终端的上下文信息。其中，终端的上下文信息中包括无线网络区域的信息。
对应的，核心网设备侧接收接入网设备侧发送的终端的无线网络区域的信息。
可选的，核心网设备侧接收到终端的无线网络区域的信息后，若确定此次需要发起寻呼，执行步骤203。
步骤203，在终端的TA信息指示的范围内除所述无线网络区域以外寻呼所述终端。
此处，核心网设备侧接收到终端的无线网络区域的信息后，若确定此次需要发起寻呼，则排除接入网设备侧已经寻呼失败的无线网络区域，即在终端的TA信息指示的范围内除所述无线网络区域以外寻呼所述终端，从而节省信令资源的浪费且提供寻呼效率。
其中，终端的TA信息指示的范围具体可以是指终端的一个或多个TA信息指示的范围。
核心网设备侧若确定此次无需发起寻呼，则可暂时不再寻呼终端，在后续需要发起寻呼时，在终端的TA信息指示的范围内除所述无线网络区域以外寻呼所述终端。
需要说明的是：步骤201和步骤202可以由接入网设备或者接入网设备内部的芯片实现，步骤203可以由核心网设备或者核心网设备内部的芯片实现。
下面仍以终端1032为例，对上述步骤201至步骤203进行具体说明。其中，步骤201至步骤203中的终端具体可以为图1中的终端1032，步骤201至步骤203中的第一接入网设备为图1中的接入网设备1022，步骤201至步骤203中的核心网设备为图1中的核心网设备101。无线网络区域包括小区1和小区2。
如图2b所示，下行数据到达后，核心网设备101将数据发给去活动态的终端1032最后连接的接入网设备1022。
接入网设备1022在无线网络区域内寻呼终端1032，具体寻呼方式参见上述描述。
若接入网设备1022在整个无线网络区域内都没有寻呼到终端1032，则接入网设备1022和核心网设备101间发起终端1032的网络连接释放过程。
具体释放过程可以是由接入网设备1022发起释放请求，然后由核心网设备101决定释放；或者，也可以是接入网设备1022发起释放指示，然后由核心网设备101根据释放指示执行释放过程。本申请中对具体的释放过程不限定，无论采用上述哪种释放过程，接入网设备1022均会发信令给核心网设备101。为了避免CN-initiated paging还在无线网络区域内再 次寻呼终端1032(图2b虚线所示的信令)，而带来不必要的信令浪费，接入网设备1022可在网络连接释放过程中发送终端1032的无线网络区域的信息给核心网设备101。
终端1032对应的网络连接释放后，从网络角度看，终端1032进入了空闲态(idle态)，若核心网设备101还需要寻呼终端1032，则发起CN-initiated paging。由于核心网设备101收到了终端1032的无线网络区域的信息，因此，发起CN-initiated paging时，可以避开无线网络区域，仅在TA或TA list范围内的除无线网络区域外的其它区域发起CN-initiated paging，即将CN-initiated paging发给TA或TA list内除无线网络区域外的其它接入网设备(即接入网络设备1023)，以使得这些接入网设备继续寻呼UE，从而有效避免无线网络区域内的重复寻呼，节省了信令资源。
上述内容从核心网设备和接入网络设备的角度，具体描述了终端进入去活动态后，寻呼该终端的实现过程。针对于上述步骤203中所涉及到的“在整个无线网络区域内都没有寻呼到终端”，从终端的角度来分析，原因可能包括以下至少一种：(1)终端移出了无线网络区域，但是未及时通知接入网络设备；(2)终端移出了无线网络区域，但是检测出处于非服务状态(out-of-service)，无法发起无线网络区域更新；(3)终端仍在无线网络区域内，但是检测出处于非服务状态，导致无法收到寻呼或无法发起寻呼响应。其中，检测出处于非服务状态具体可以是指终端根据网络侧发送的测量配置信息，在设定时间内找不到合适的小区驻留。可以理解的是,本申请实施例对上述设定时间的时间长度不做限定。
可选的，本申请又一实施例提供了一种用于去活动态的终端处于非服务状态后的处理方式，图3为本申请该实施例提供的一种通信方法所对应的流程示意图，如图3所示，该方法可以包括：
步骤301，检测出去活动态的终端处于非服务状态；
此处，对于去活动态的终端，若终端在设定时间内找不到合适的小区，可以认为终端处于非服务状态。当检测出终端处于非服务状态后，可以执行步骤302。
步骤302，确定所述终端的目标小区；
其中，当去活动态的终端处于非服务状态时，为了使该终端能够重新回到网络，可以进行小区选择或小区重选，进而为该终端确定目标小区。
其中，所述确定所述终端目标小区包括：第一时间长度的时间内没有确定出所述目标小区，确定进入空闲态的所述终端的所述目标小区，其中，所述空闲态是所述终端在第一时间长度的时间到达后进入的；或者，所述确定所述终端的目标小区包括：在所述第一时间长度的时间内，确定出所述终端的目标小区。
步骤303，向目标小区对应的接入网设备发送第一指示信息，所述第一指示信息用于指示所述终端在接入到所述目标小区之前处于非服务状态；
此处，终端驻留到步骤302中确定出的目标小区后，可向目标小区对应的接入网设备上报其在接入目标小区之前处于非服务状态，可以理解为通知了接入网设备其接入网络的原因。
对应的，接入网设备侧会接收到该第一指示信息。
步骤304，根据第一指示信息确定出所述终端在接入到所述目标小区之前处于非服务状态。
当接入网设备侧接收到第一指示信息后，通过解析第一指示信息，可以获知终端在接 入目标小区之前处于非服务状态。
需要说明的是：步骤301至步骤303可以由一通信装置实现，该通信装置可以是终端，也可以是终端内部的芯片，步骤304可以由接入网设备或者接入网设备内部的芯片实现。
可以理解的是，通信装置为终端内部的芯片时，其接收或者发送信息之前，还可能会经过终端内部其它模块的处理，例如射频模块的变频处理等，本申请实施例对此不做限定。
根据上述内容可知，终端从非服务状态重新接入网络后，向接入网络设备发送第一指示信息，从而使得接入网设备能够根据第一指示信息及时得知终端在接入目标小区之前处于非服务状态，那么接入网设备可以获知终端接入网络的原因。
具体来说，步骤301和步骤302中，检测出去活动态的终端处于非服务状态后，终端可执行小区选择或小区重选，被选择出的小区即为目标小区。
可选的，检测出去活动态的终端处于非服务状态时，可启动定时器，定时器的时间长度为第一时间长度。第一时间长度可以是网络配置给终端的，或者协议预定义的。其中，定时器可以用于确定终端是否需要继续保留在去活动态或者是用于控制终端进入空闲态的时机，或者定时器也可以用于其他的作用。
可以理解的是，定时器是可选的，也可以不需要定时器。例如，当没有定时器时，一种可能的实现方式是，终端检测出处于非服务状态后直接进入空闲态。
本申请中，考虑到可能会出现终端长时间找不到合适的小区的现象，若终端仍一直保存有上下文信息，则会导致终端存储资源的浪费，或者接入网设备在终端长时间找不到合适的小区的情况下，却保留上下文信息，也会导致接入网设备存储资源的浪费。因此，可通过启动定时器来衡量终端是否在第一时间长度的时间内找到合适的小区，若终端未能在第一时间长度的时间内找到合适的小区，则可在定时器到期后清空上下文信息，并进入空闲态。
步骤303中，终端发送第一指示信息的实现方式可以有多种，例如，通过信令或者消息携带该第一指示信息，比如终端可以通过RRC信令发送第一指示信息，更进一步地，在不同的场景中，RRC信令可以为RRC连接建立请求消息或者RRC连接恢复请求消息。其中，第一指示信息可以是表示接入原因的信元，具体可以为重新进入服务区(re-enter service)，从而接入网设备可通过解析第一指示信息，获知终端的接入原因。
可选地，第一指示信息还可以包括终端处于非服务状态的其它信息，比如位置信息，时间信息，非服务状态的持续时间信息，非服务状态的起始时间信息等。
步骤304中，接入网设备接收到第一指示信息，得知终端在接入目标小区之前处于非服务状态，进一步可以根据第一指示信息更新终端的状态，例如，将终端更新为连接态或空闲态或去活动态等，从而便于后续正常寻呼或找到终端。
下面结合图4对上述通信方法进行具体说明，以下实施例中，以终端和接入网设备实现通信方法为例进行说明。
步骤401，检测出去活动态的终端处于非服务状态。
步骤402，终端启动定时器。
该定时器的长度为第一时间长度。
在定时器启动后，可能出现两种情形：第一种情形，终端在所述定时器运行的第一时间长度的时间内没有确定出目标小区；第二种情形，终端在所述定时器运行的第一时间长度的时间内，确定出所述终端的目标小区。
步骤403，判断在定时器运行的第一时间长度的时间内是否确定出目标小区，若在第一时间长度的时间内没有确定出目标小区，执行步骤404，若在第一时间长度的时间内确定出目标小区，执行步骤411。
以下步骤404-步骤410为在第一时间长度的时间内没有确定出目标小区的情形下，所可能执行的步骤。
步骤404，终端在定时器运行的第一时间长度的时间内没有确定出目标小区，即未找到合适的小区，定时器到期，终端进入空闲态。
本申请中，终端进入空闲态具体是指终端清空上下文信息。上下文信息可以包括以下至少一种：Anchor接入网络设备发送给终端的无线网络区域的信息，信令无线承载(Signalling Radio Bearer，SRB)配置信息、数据无线承载(Data Radio Bearer，DRB)配置信息。
可选地，步骤404后，可以继续执行步骤405。
步骤405，确定进入空闲态的终端的目标小区。
此时，进入空闲态的终端，可以通过小区重选或者小区选择的流程确定目标小区。
步骤405之后，执行步骤406。
步骤406，终端向目标小区对应的接入网设备发送RRC连接建立请求消息，所述RRC连接建立请求消息中包括第一指示信息。
关于第一指示信息的内容可以参考上述实施例的相关描述，此处不再赘述。
步骤407，接入网设备接收第一指示信息。
接入网设备可以根据第一指示信息确定出终端在接入到所述目标小区之前处于非服务状态。
本申请中，接入网设备还可以根据RRC连接建立请求消息，确定出终端当前的位置信息。可选地，步骤407之后，可以继续执行步骤408。
步骤408，接入网设备判断是否存在终端的上下文信息，若存在，则执行409，若不存在，则执行410。
步骤409，删除所述终端的上下文信息，并释放所述终端对应的核心网和接入网之间的网络连接。
本申请中，接入网设备确定存在终端的上下文信息可以是指接入网设备确定自身存储有终端的上下文信息(此时接入网设备为终端的Anchor接入网络设备)，此种情况下，接入网设备可直接删除终端的上下文信息，并释放对应的核心网和接入网之间的网络连接。
其中，释放对应的核心网和接入网之间的网络连接的具体实现方式可以有多种，例如1，接入网设备向核心网设备发送释放请求，核心网设备根据释放请求决定释放终端对应的网络连接；例如2，接入网设备向核心网设备发送释放指示，核心网设备根据释放指示执行释放终端对应的网络连接的操作。本申请对具体释放过程不做限定。
接入网设备确定存在终端的上下文信息也可以是指接入网设备确定其它接入网设备存储有终端的上下文信息(此时接入网设备不是终端的Anchor接入网络设备，而存储有终端的上下文信息的其它接入网设备为终端的Anchor接入网络设备)，此种情况下，接入网设备向所述其它接入网设备发送第二指示信息，第二指示信息用于指示所述其它接入网设备删除所述终端的上下文信息，以及释放终端对应的核心网和接入网之间的网络连接。
可选地，步骤409之后，可以继续执行步骤410。
步骤410，配置终端为去活动态或者连接态或者空闲态。
此处，接入网设备可以根据终端的业务类型、业务量大小等信息，配置终端进入去活动态或者连接态或者空闲态。比如终端没有任何业务请求，仅仅是为了发送第一指示信息，接入网设备可以配置终端为空闲态，或者为了避免终端从空闲态转为连接态的信令开销，接入网设备可以配置终端为去活动态；如果终端有业务请求，或者业务量大，接入网设备可以配置终端为连接态。通过这种方式，接入网设备能够更好地选择适合终端的状态，避免了不必要的状态转换过程，节省了状态转换过程中的信令开销。
以下步骤411-415为若在第一时间长度的时间内确定出目标小区，所可能执行的步骤。
步骤411，终端向目标小区对应的接入网设备发送RRC连接恢复请求消息，所述RRC连接恢复请求消息中包括所述第一指示信息。
步骤412，接入网设备接收第一指示信息。
接入网设备可以根据第一指示信息确定出终端在接入到所述目标小区之前处于非服务状态。
可选地，接入网设备还可以根据RRC连接恢复请求消息，确定出终端当前的位置信息。可选地，步骤412之后，可以继续执行步骤413。
步骤413，判断是否存在终端的上下文信息，若存在，则执行414，若不存在，则执行415。
步骤414，保留终端的去活动态。
本申请中，接入网设备确定存在终端的上下文信息可以是指接入网设备确定自身存储有终端的上下文信息(此时接入网设备为终端的Anchor接入网络设备)，此种情况下，接入网设备可直接保留终端的去活动态；或者，接入网设备也可以重新配置终端进入去活动态，即重新为终端配置无线网络区域的信息。
接入网设备若确定自身未存储有所述终端的上下文信息，则可向其它接入网设备获取所述终端的上下文信息，若确定其它接入网设备中存储有所述终端的上下文信息，则获取终端的上下文信息，并保留所述终端的去活动态(此时接入网设备不是终端的Anchor接入网络设备，而存储有终端的上下文信息的其它接入网设备为终端的Anchor接入网络设备)。
可以理解的，接入网设备还可以配置终端进入连接态或空闲态，比如终端没有任何业务请求，仅仅是为了发送第一指示信息，接入网设备可以配置终端为空闲态；如果终端有业务请求，或者业务量大，接入网设备可以配置终端为连接态。接入网设备可以根据终端的业务类型，业务量大小等信息，配置终端进入去活动态或者连接态或者空闲态，从而更好的选择适合终端的状态，避免了不必要的状态转换过程，节省了状态转换过程中的信令开销。
步骤415，接入网设备未获取到终端的上下文信息(例如，自身未存储有终端的上下文信息，且其它接入网设备也未存储有终端的上下文信息导致接入网设备未获取到)，则可配置所述终端为去活动态或者连接态或者空闲态。
比如，接入网设备可以根据终端的业务类型，业务量大小等信息，配置终端进入去活动态或者连接态或者空闲态，从而更好的选择适合终端的状态，避免了不必要的状态转换过程，节省了状态转换过程中的信令开销。
根据上述内容可知，本申请提供了一种去活动态的终端处于非服务状态后的处理方 式，具体来说，终端可启动定时器，若在定时器运行的第一时间长度的时间内没有确定出目标小区，则由于终端处于非服务状态的时间较长，因此，可清空去活动态配置信息并进入空闲态，从而节省存储空间，且后续确定出目标小区后，可向接入网设备发送RRC连接建立请求消息，便于接入网设备重新配置终端的状态。若终端在第一时间长度的时间内确定出目标小区，则说明终端处于非服务状态的时间较短，其去活动态配置信息依然是有效的，因此终端可向接入网设备发送RRC连接恢复请求消息，并由接入网设备保留终端的去活动态，便于后续正常寻呼或找到终端。
可选的，本申请中，图3所示出的通信方法可以应用于图2a-2b所示出场景。具体来说，在图2a-2b所示的通信方法中，接入网设备在无线网络区域内寻呼终端时，若终端出现非服务状态(例如，上述描述的原因2和原因3)，会导致接入网设备和核心网设备均无法正常寻呼到终端，具体来说，若终端是由于原因(2)而导致在无线网络区域内未被寻呼到，这种情况下，采用图2a-2b中的方法，由于终端已经移出了无线网络区域，因此核心网设备不在无线网络区域内发起寻呼也不会带来任何问题，但有可能会因为终端处于非服务状态而寻呼不到终端。若终端是由于原因(3)而导致在无线网络区域内未被寻呼到，这种情况下，采用图2a-2b中的方法，由于终端仍在无线网络区域，而核心网设备不在无线网络区域内发起寻呼，有可能会导致永远无法寻呼到终端。而本申请实施例图3中所描述的去活动态的终端处于非服务状态后的处理方式，使得终端能够重新回到网络，从而能够有效解决由于终端处于非服务状态而导致采用图2a-2b中的方法无法正常寻呼到终端的问题。可以理解的是，除了以上例举的无法正常寻呼到终端的场景，还可能存在其他场景，本申请实施例不一一举例说明。
现有长期演进(Long Term Evolution，LTE)系统中，引入了对空闲态的终端进行负载均衡的技术，通过定义多个频点优先级来避免空闲态的终端在频率间驻留不均匀的问题。为了进一步使得部分终端重选到相邻频点或相邻小区，LTE中还引入了各频点或各邻区的的重分布参数，对于服务频点或服务小区，也分配了相应的重分布参数。接入网设备可通过寻呼消息或系统消息将小区的频点优先级和重分布参数发送给各个终端，从而使得各个终端能够根据小区的频点优先级和重分布参数，尽可能均匀地选择驻留的频点或小区。
而针对于去活动态的终端来说，接入网设备通过专有信令为其配置无线网络区域的信息，因此，去活动态的终端在无线网络区域内移动时，终端的上下文信息可直接在无线网络区域内的不同接入网设备之间进行传递，而无需经过核心网设备。因此，去活动态的终端若重选到无线网络区域包括的小区，则无需经过核心网设备进行终端的上下文信息的转发，节省信令开销。
考虑到去活动态的终端会接收到接入网设备发送的小区的频点优先级和重分布参数，若终端根据小区的频点优先级和重分布参数，则很有可能重选到无线网络区域之外的小区，这种情形下，需要经过核心网设备在接入网设备间转发终端的上下文信息，进而带来信令开销和延迟，而且容易发生终端的上下文信息转发失败，进而影响用户体验。
基于此，本申请提供一种小区重选方法，用于避免去活动态终端在无线网络区域内移动时优先重选到无线网络区域之外的小区而造成较多的信令开销和延迟的问题。
图5本申请提供的一种小区重选方法对应的流程示意图，该方法的执行主体可以为终端或者终端内部的芯片。如图5所示，该方法可以包括：
步骤501，接收接入网设备为终端配置的无线网络区域的信息。
此处，无线网络区域包括一个或多个小区，所述无线网络区域的信息包括用于标识所述一个或者多个小区的信息，即小区的标识；小区的标识具体可以包括：小区的小区全局标识(Cell Global Identity，CGI)、物理小区标识(Physical Cell Identity，PCI)、小区标识(cell identity)。
步骤502，根据所述无线网络区域的信息进行小区重选。
本申请中，终端在无线网络区域内移动时，可根据接收到的接入网设备发送的无线网络区域的信息进行小区重选，从而能够尽可能优选到无线网络区域内的小区/频率，有效避免优先重选到无线网络区域之外的小区而造成较多的信令开销和延迟的问题。
可选地，无线网络区域的信息中还可以包括第一优先级信息，该第一优先级信息包括所述无线网络区域包括的一个或者多个小区/频率的优先级信息。可选地，第一优先级信息可以包括小区/频率的重选优先级，还可以包括小区/频率的重选子优先级、频率重分布参数，小区重分布参数等至少一种信息。
可选地，终端还可能通过系统广播消息或者专用信令接收到接入网设备发送的第二优先级信息。其中，第二优先级信息可以包括小区/频率的重选优先级，还可以包括小区/频率的重选子优先级、频率重分布参数，小区重分布参数等至少一种信息，本申请对第二优先级信息中包括的具体内容不做限定，本领域技术人员可根据实际需要设置第二优先级信息包括上述所描述的一种或多种信息。可选的，通过系统广播消息发送的第二优先级信息可以包括与传统的公共优先级类似的信息，通过专用信令发送的第二优先级信息可以包括与传统的专用优先级类似的信息。
一种可能的实现方式中，终端在进行小区重选时，可以先忽略第二优先级信息，根据无线网络区域的信息进行小区重选，或者，也可以综合考虑无线网络区域的信息和第二优先级信息进行小区重选。基于此，本申请可能具有多种可能的实现方式，下面具体描述四种方式。
可以理解的是，以上第二优先级信息中所对应的小区/频率可以和无线网络区域包括的一个或者多个小区/频率重合或不重合，例如可能是邻区列表中包括的小区/频率。以上重合可以是指完全重合或者部分重合。
以下实施例以优先级信息以及无线网络区域信息以小区为粒度，且以优先级信息包扩小区优先级和小区重分布参数为例，进行举例说明。
方式一：终端接收接入网设备为终端配置的无线网络区域的信息，并根据无线网络区域的一个或多个小区的信号质量进行小区重选。
具体来说，终端获取一个或多个小区的信号质量，并可根据无线网络区域内的一个或多个小区的信号质量，从所述一个或多个小区选择出信号质量最好的小区(设为小区1-1)，并重选到小区1-1。
进一步地，考虑到小区1-1可能不适合接入，因此，终端在选择出信号质量最好的小区1-1后，可先判断下小区1-1是否适合接入，若不适合，则终端可放弃重选到小区1-1，并从一个或多个小区中除小区1-1以外的信号质量最好的小区(设为小区1-2)，在确定小区1-2适合接入后，重选到小区1-2。
可选地，如果终端接收到的无线网络区域的信息中还包括接入网设备为终端配置的无线网络区域内的一个或多个小区的重分布参数，此时终端可以根据无线网络区域内的一个或多个小区的信号质量和重分布参数，确定出符合条件的小区1-3，并重选到小区1-3。
进一步地，考虑到小区1-3可能不适合接入，因此，终端在选择出符合条件的小区1-3后，可先判断下小区1-3是否适合接入，若不适合，则终端可放弃重选到小区1-3，并从一个或多个小区中除小区1-3以外的小区中进一步根据重分布参数确定合适的小区(设为小区1-4)，在确定小区1-4适合接入后，重选到小区1-4。
举个例子，无线网络区域包括小区1a、小区1b、小区1c和小区1d，终端可从小区1a、小区1b、小区1c和小区1d中选择出信号质量最好的小区，并重选到该小区。如果终端接收到的无线网络区域的信息中还包括接入网设备为终端配置的小区1a、小区1b、小区1c和小区1d的重分布参数，则终端也可以根据无线网络区域内的小区的信号质量和重分布参数，确定出符合条件的小区，并重选到该小区。
下面举个例子说明根据小区1a、小区1b、小区1c和小区1d的信号质量和重分布参数进行小区重选的具体过程。
小区1a、小区1b、小区1c和小区1d中信号质量符合要求(信号质量大于预设的信号质量阈值)的小区包括小区1a、小区1b、小区1c。UE1的服务小区为小区0，小区0的重分布因子redistrFactor[0]＝5，小区1a的重分布因子redistrFactor[1a]＝4，小区1b的重分布因子redistrFactor[1b]＝6，小区1c的重分布因子redistrFactor[1c]＝5。则全部的重分布因子之和total redistrFactor为：5+4+6+5＝20。
其中服务小区的重分布范围redistrRange[0]＝redistrFactor[0]/total redistrFactor＝5/20＝0.25；
UE ID＝(IMSI mod 100)*2+1；
假设UE 1的IMSI mod 100的余数是5，则UE ID＝5*2+1＝11<＝200*redistrRange[0]＝50。此时UE 1重选到cell 0。
类似的，可以得到小区1a的redistrRange[1a]＝4/20＝0.2；
小区1b的redistrRange[1b]＝6/20＝0.3；
小区1c的redistrRange[1c]＝5/20＝0.25；
因此，若UE 2的IMSI mod 100余数是50，则UE ID2＝2*50+1＝101；此时符合
(redistrRange[0]+redistrRange[1a])*200＝0.45*200＝90<101<＝
(redistrRange[0]+redistrRange[1a]+redistrRange[1b])*200＝0.75*200＝150；
因此，UE 2重选入小区1b。
方式二：终端接收到的无线网络区域的信息中还包括第一优先级信息，所述第一优先级信息包括所述无线网络区域包括的一个或者多个小区的优先级信息；进而终端可根据一个或多个小区的第一优先级信息进行小区重选。
具体来说，参见上述内容的介绍，无线网络区域的信息可以为小区列表的形式，小区列表中还可以包括第一优先级信息。如表2所示，为包括第一优先级信息的小区列表的内容示意。
表2：第一优先级信息内容示意
小区标识 小区的优先级信息
小区2-1 2
小区2-2 1
如表2所示，小区2-1对应的优先级为2，小区2-2对应的优先级为1，说明小区2-2的优 先级低于小区2-1的优先级，因此，终端根据第一优先级信息可优先重选到小区2-1。可以理解的是，也可以是优先级数值越大标识优先级越高，本申请对此不做限定。
同样地，考虑到小区2-1可能不适合接入，因此，终端在选择出优先级最高的小区2-1后，可先判断下小区2-1是否适合接入，若不适合，则终端可放弃重选到小区2-1，并从一个或多个小区中除小区2-1以外的优先级最高的小区2-2，在确定小区2-2适合接入后，重选到小区2-2。
需要说明的是：(1)终端也可以通过其它方式获取到第一优先级信息，例如，终端通过接收接入网设备发送的专有信令获取到第一优先级信息。
(2)上述示例中，是以优先级最高的小区仅有一个为例，若优先级最高的小区有两个或两个以上，则终端可在选择出优先级最高的小区后，从最优先级最高的小区中选择出信号质量最好的小区，并重选到该小区。如果终端接收到的第一优先级信息中还包括接入网设备为终端配置的一个或多个小区的重分布参数，则终端也可以根据无线网络区域内的一个或多个小区的信号质量和重分布参数，从优先级最高的小区中确定出符合条件的小区，并重选到该小区。具体实现过程参见方式一中的描述，此处不再赘述。
若终端采用上述方式未能从优先级最高的小区中选择出合适的小区，则终端可排除优先级最高的小区，并从无线网络区域中剩下的小区中选择出优先级最高的小区，根据信号质量(和重分布参数)进行小区重选，若选择出合适的小区，则重选到该小区，若未能选择出合适的小区，则按照上述方式类推，直到选择出合适的小区。
可以理解的是，若终端在无线网络区域包括的小区中未能选择出合适的小区，则可在邻区列表中除所述无线网络区域之外的小区中进行小区重选，具体重选方式与LTE中的小区重选流程类似，此处不再赘述。如此，终端在无法重选到无线网络区域内的小区的情况下，则可重选到无线网络区域之外的小区，且，终端在重选到无线网络区域之外的小区时，可排除无线网络区域包括的小区，从而有效提高重选效率。
方式三：终端接收接入网设备发送的第二优先级信息，所述第二优先级信息包括至少一个小区的优先级信息；终端根据无线网络区域的信息和所述第二优先级信息进行小区重选。
举个例子，无线网络区域包括小区3-1和小区3-2，第二优先级信息中包括小区3-1、小区3-2和小区3-3的优先级信息，其中小区3-1的优先级为2、小区3-2的优先级为1、小区3-3的优先级为1，终端根据第二优先级信息得到小区3-1和小区3-2的优先级，进而从小区3-1和小区3-2中选择出优先级最高的小区3-1，并重选到小区3-1。
同样地，考虑到小区3-1可能不适合接入，因此，终端在选择出优先级最高的小区3-1后，可先判断下小区3-1是否适合接入，若不适合，则终端可放弃重选到小区3-1，并从一个或多个小区中除小区3-1以外的优先级最高的小区3-2，在确定小区3-2适合接入后，重选到小区3-2。
需要说明的是，上述示例中，是以优先级最高的小区仅有一个(即小区3-1)为例，若优先级最高的小区有两个或两个以上，则终端可在选择出优先级最高的小区后，从最优先级最高的小区中选择出信号质量最好的小区，并重选到该小区。如果第二优先级信息中还包括至少一个小区的重分布参数，则终端根据第二优先级信息可得到无线网络区域内的小区的重分布参数，进而也可以根据无线网络区域内的小区的信号质量和重分布参数，确定出符合条件的小区，并重选到该小区。具体实现过程参见方式二中的描述，此处不再赘述。
方式四：终端接收接入网络设备发送的第二优先级信息，所述第二优先级信息包括至少一个小区的优先级信息；终端根据所述第一优先级信息和第二优先级信息，进行小区重选。
具体来说，以小区4-1为例，若第一优先级信息中包括小区4-1的优先级，第二优先级信息中也包括小区4-1的优先级，则终端可将第一优先级信息和第二优先级信息中所包括的较高的优先级作为小区4-1的优先级，例如，第一优先级信息中小区4-1的优先级为1，第二优先级信息中小区4-1的优先级为2，则终端可确定小区4-1的优先级为2。
举个例子，第一优先级信息包括小区4-1、小区4-2的优先级信息，具体如表3a所示；第二优先级信息包括小区4-1、小区4-3、小区4-4的优先级信息，具体如表3b所示。
表3a：第一优先级信息的内容示意
小区标识 第一优先级信息
小区4-1 1
小区4-2 1
表3b：第二优先级信息的内容示意
小区标识 第二优先级信息
小区4-1 2
小区4-3 1
小区4-4 1
终端根据第一优先级信息和第二优先级信息得到小区4-1的优先级为2、小区4-2的优先级为1，由于小区4-3和小区4-4不是无线网络区域包括的小区，因此，终端根据小区4-1和小区4-2的优先级选择出优先级最高的小区4-1，并重新到小区4-1。
需要说明的是，上述示例中，是以优先级最高的小区仅有一个(即小区4-1)为例，若优先级最高的小区有两个或两个以上，则终端可在选择出优先级最高的小区后，从最优先级最高的小区中选择出信号质量最好的小区，并重选到该小区。
如果第一优先级信息中还包括接入网设备为终端配置的一个或多个小区的重分布参数，第二优先级信息中还包括至少一个小区的重分布参数，则终端还可以根据第一优先级信息和第二优先级信息得到无线网络区域的小区的重分布参数，需要说明的是，若无线网络区域的某一小区的优先级采用的是第一优先级信息中的优先级，则该小区的重分布参数也应采用第一优先级信息中的重分布参数；若无线网络区域的某一小区的优先级采用的是第二优先级信息中的优先级，则该小区的重分布参数也应采用第二优先级信息中的重分布参数。例如，终端根据第一优先级信息和第二优先级信息得到小区4-1的优先级为2(此时，采用了第二优先级信息中小区4-1的优先级)，则可进一步根据第二优先级信息，得到小区4-1的重分布参数。
如此，采用上述方式确定出无线网络区域内的小区的重分布参数后，可根据优先级最高的小区的信号质量和重分布参数进行小区重选。具体方式参见方式二和方式三中的描述。
根据上述内容可知，本申请实施例的方案，在进行小区重选时方式一与方式二、方式三、方式四的差异在于：方式一中不考虑小区的优先级，而是根据信号质量来选择出符合 要求的小区，并基于这些符合要求的小区的信号质量和重分布参数来选择合适的小区；方式二、方式三、方式四中均考虑小区的优先级，进而基于优先级、信号质量等来选择合适的小区。
方式二、方式三与方式四的差异在于：方式二中所涉及到的无线网络区域的小区的优先级和重分布参数是由接入网设备为终端配置无线网络区域的信息时配置的；方式三中所涉及到的无线网络区域的小区的优先级和重分布参数是基于第二优先级信息确定的；方式四中所涉及到的无线网络区域的小区的优先级和重分布参数是根据第一优先级信息和第二优先级信息来共同确定的。
根据上述所描述的各种小区重选方法可知，本申请中，当执行小区重选时，终端将优先考虑无线网络区域内的小区。在无线网络区域内的小区的信号质量满足重选条件的情况下，终端将重选到无线网络区域内的小区。
在小区重选期间，去活动态的终端对无线网络区域内的小区给予更高的优先级。
需要说明的是，本申请实施例中所述的信号质量是一个广义的概念，可以理解为是衡量信号接收状况的一个参数，例如可以包括参考信号接收功率(RSRP，Reference Signal Receiving Power)、参考信号接收质量(RSRQ，Reference Signal Receiving Quality)等。
本申请中的上述方式一至方式四是以小区的重分布参数为例，本申请中也可以适用于频率重分布参数。
本申请中，上述方式一至方式四适用于终端在无线网络区域内移动时进行重选的过程，若终端移出了无线网络区域，则终端可使用与传统小区重选方式类似的方式进行小区重选。
