技术领域
本申请实施例涉及通信技术，涉及但不限于小区测量方法及装置、设备、存储介质。
背景技术
依据当前3GPP TS24.501中3GPP接入类型的服务区域限制的描述，服务区域限制是在用户设备(User Equipment，UE)注册或配置更新命令过程中，由网络通过服务区域列表(Service area list IE)配置给UE的一组跟踪区域指示(Tracking Area Identity，TAI)列表。然而，在服务区域限制场景下，经常出现UE无法提供正常服务的问题。
发明内容
有鉴于此，本申请实施例提供的小区测量方法及装置、设备、存储介质，能够增大服务区域限制场景下的UE切换或重选至可用区域的小区的概率，从而提高UE的通信服务性能。本申请实施例提供的小区测量方法及装置、设备、存储介质是这样实现的：

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请的具体技术方案做进一步详细描述。以下实施例用于说明本申请，但不用来限制本申请的范围。除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中所使用的术语只是为了描述本申请实施例的目的，不是旨在限制本申请。在以下的描述中，涉及到“一些实施例”，其描述了所有可能实施例的子集，但是可以理解，“一些实施例”可以是所有可能实施例的相同子集或不同子集，并且可以在不冲突的情况下相互结合。需要指出，本申请实施例所涉及的术语“第一\第二\第三”不代表针对对象的特定排序，可以理解地，“第一\第二\第三”在允许的情况下可以互换特定的顺序或先后次序，以使这里描述的本申请实施例能够以除了在这里图示或描述的以外的顺序实施。
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定。本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请实施例的技术方案可以应用第四代移动通信系统(the 4th generation mobile communication system，4G)、第五代移动通信技术(5th-Generation wireless communication technology，5G)新空口(New Radio，NR)系统或未来的通信系统，也可以用于其他各种无线通信系统，例如：窄带物联网(Narrow Band-Internet of Things，NB-IoT)系统、全球移动通讯系统(Global System of Mobilecommunication，GSM)、增强型数据速率GSM演进(Enhanced Data rate for GSM Evolution，EDGE)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、码分多址2000(Code Division Multiple Access，CDMA2000)系统、时分同步码分多址(Time Division-Synchronization Code Division Multiple Access，TD-SCDMA)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、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)或通用移动通信系统(Universal Mobile Telecommunication System，UMTS)等。
图1示出了本申请实施例可能适用的一种网络架构。如图1所示，本实施例提供的网络架构包括：网络设备101和用户设备(User Equipment，UE)102，还包括网络设备103和网络设备104等；其中，UE当前驻留在网络设备101所覆盖的小区(称为UE的服务小区)，网络设备103和网络设备104所覆盖的小区是网络设备101所覆盖的小区的邻小区。
本申请实施例所涉及到的UE可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户终端设备(terminal device)或移动台(Mobile Station，MS)等等。本申请实施例所涉及到的网络设备是一种部署在无线接入网中用以为UE提供无线通信功能的设备。
当UE处于业务连接状态并保持业务服务时，从一个小区移动到另一个小区，原来的服务小区不再给UE继续提供服务，为了不中断业务，无线承载系统将寻找较为合适的小区或网络设备为UE继续提供服务，实现无线网络无缝覆盖的移动性管理，这就是小区切换。
小区重选(cell reselection)是指UE在空闲模式下通过监测邻小区和服务小区的信号质 量或强度以选择一个合适的小区提供服务信号的过程。通过小区重选，可以最大程度地保证空闲模式下的UE驻留在合适的小区。在空闲模式下，通过对服务小区和邻小区的测量值的监控，来触发小区重选。重选触发条件的核心内容就是：存在有比服务小区更好的小区，且该更好的小区在一段时间内都保持较好的接收信号质量。这样，一方面，使得UE能够尽量重选到更好的小区上；另一方面，又保证了一定的稳定性，避免频繁的重选震荡。
依据通信协议3GPP TS24.501中对3GPP接入类型的服务区域限制的描述，服务区域限制是指在UE注册或配置更新命令的过程中，由网络设备通过服务区域列表(Service area list IE)配置给UE的一组TAI列表。Service area list IE中包含的TAI列表可以指示“可用区域”或者“不可用区域”。“可用区域”和“不可用区域”都属于UE的注册公用陆地移动网络(Registerd Public Land Mobile Network，RPLMN)或者等效公用陆地移动网(Equivalent Public Land Mobile Network，EPLMN)，并由最多16个TAI构成。
当UE驻留在可用区域的小区，UE应该进入5GMM注册的正常服务(5GMM-REGISTERED.NORMAL-SERVICE)状态，此时UE可以提供正常服务。相反，当UE驻留在不可用区域的小区，UE进入5GMM注册的不允许服务(5GMM-REGISTERED.NON-ALLOWED-SERVICE)，此时UE无法提供正常服务，且UE只能发起由于紧急业务或高优先级用户接入的注册和服务请求过程来获取网络服务，如果此时UE的无线资源控制(Radio Resource Control，RRC)层处于连接态，UE也无法发起正常的会话业务来获取服务。
在UE未收到网络设备下发的用以指示可用区域或不可用区域的TAI列表的场景下，UE的小区测量和小区重选的相关内容如下(1)至(5)所述：
(1)如果服务小区的小区选择接收电平值(Cell selection RX level value，Srxlev)>SIntraSearchP，并且服务小区的小区选择质量值(Cell selection quality value，Squal)>SIntraSearchQ，UE可以不执行同频测量；
其中，Srxlev是指小区选择/重选过程中计算得到的小区选择接收电平值(dB)，该值与测量的参考信号接收功率(Reference Signal Receiving Power，RSRP)有关，即RSRP维度的绝对信号强度，SintraSearchP为同频RSRP测量启动门限；Squal是指小区选择或重选过程中计算得到的小区选择质量值(dB)，该值与测量的参考信号接收质量(Reference Signal Receiving Quality，RSRQ)有关，即RSRQ维度的相对质量，SintraSearchQ为同频RSRQ测量启动门限。
(2)如果服务小区的Srxlev>SnonIntraSearchP，并且服务小区的Squal>SnonIntraSearchQ，UE可以不执行同等优先级和低优先级频点测量；
其中，SnonIntraSearchP为异频RSRP测量启动门限，SnonIntraSearchQ为异频RSRQ测量启动门限。
(3)异频高优先级小区重选需要满足：在时间间隔TreselectionRAT内，邻频小区的Squal>ThreshX,HighQ或者邻频小区的Srxlev>ThreshX,HighP并在原小区上驻留超过1秒；
其中，ThreshX,HighQ为RSRQ相关的高优先级重选门限，ThreshX,HighP为RSRP相关的高优先级重选门限。
(4)异频低优先级小区重选需要满足：在时间间隔TreselectionRAT内，服务小区的Squal<ThreshServing,LowQ，并且邻频小区的Squal>ThreshX,LowQ或者服务小区的Srxlev<ThreshServing,LowP并且邻频小区的Srxlev>ThreshX,LowP，并在服务小区上驻留超过1秒。
其中，ThreshServing,LowQ为服务小区的RSRQ相关的低优先级重选门限，ThreshX,LowQ为邻频小区的RSRQ相关的低优先级重选门限；ThreshServing,LowP为服务小区的RSRP相关的低优先级重选门限，ThreshX,LowP为邻频小区的RSRP相关的低优先级重选门限。
(5)同频或等优先级频点的小区重选需要满足R准则，即：
Rs＝Qmeas,s+Qhyst–Qoffsettemp；
Rn＝Qmeas,n-Qoffset–Qoffsettemp；
在时间间隔TreselectionRAT内满足邻小区的等级(Rank)值(即Rn)高于服务小区的Rank值(Rs)。
其中，Rs为服务小区的R测量值，Rn为邻小区的R测量值，Qmeas,s为用于重选的服务小区的平均RSRP测量值，Qmeas,n为用于重选的邻小区的平均RSRP测量值，Qhyst、Qoffset和Qoffsettemp为特定值。
需要说明的是，上述内容仅仅是帮助理解本申请实施例提供的小区测量方法，并不对本申请实施例提供的方法、装置、设备以及存储介质侧的技术方案的范围造成限制。
本申请实施例提供一种小区测量方法，图2为本申请实施例提供的小区测量方法的实现流程示意图，如图2所示，该方法可以包括以下步骤201至步骤202：
步骤201，在UE接收到网络设备下发的用以指示可用区域或不可用区域的TAI列表的场景下，确定基于小区测量得到的原始测量结果。
在UE收到网络侧配置的可用区域或不可用区域的TAI列表，说明UE可能处于可用区域或不可用区域。根据网络配置和UE的驻留情况，UE可能处于场景一或场景二下，其中：
场景一：UE成功注册到一个公共陆地移动网(Public Land Mobile Network，PLMN)，并驻留到了网络配置的可用区域的小区上(例如图3所示)；或者，UE成功注册到一个PLMN，并驻留到了网络配置的不可用区域以外的小区上；此场景下，UE可提供正常服务，UE提供的服务不受限制。
场景二：UE成功注册到一个PLMN，并驻留到了网络配置的可用区域以外的小区上；或者，UE成功注册到一个PLMN，并驻留到了网络配置的不可用区域的小区上(例如图3所示)；此场景下，除了紧急业务和高优先级用户的业务，UE无法提供正常服务，UE提供的服务受限。
然而，基于相关协议框架和UE实现机制，在场景一的情况下，如果UE处于可用区域边缘且存在不可用区域的邻小区，那么可能会出现这种情况：由于UE重选到不可用区域的小区或上报邻小区测量报告导致网络将UE切换到不可用区域的小区，这将导致用户无法发起新的业务或出现业务断流的情况，从而影响用户体验。
在场景二的情况下，如果UE驻留在当前不可用区域的小区，无法提供正常的服务。只有当UE重选到可用区域的小区或上报邻小区的测量报告使得网络将UE切换到可用区域的小区后，才能重新发起正常业务，恢复正常服务。但是，当UE处于不可用区域的边缘时，即使存在可提供正常服务的邻小区，仍可能出现UE长时间无法重选或切换到可用区域小区的情况，这将导致UE在较长时间内无法为用户提供正常服务，影响用户体验。
在本申请实施例中，通过如下步骤202，即对基于小区测量得到的原始测量结果进行修改，从而使得修改后得到的目标测量结果能够增大UE切换或重选至可用区域的小区的概率，进而解决上述场景一和场景二存在的问题。
步骤202，对所述原始测量结果进行修改，得到目标测量结果；其中，所述目标测量结果用于小区切换或小区重选，所述目标测量结果相比于所述原始测量结果，能够增大所述UE切换或重选至所述可用区域的小区的概率。
对原始测量结果修改的方式可以是多种多样的。比如，如下实施例中提供的修改UE的服务小区或邻小区的接收信号测量值或者对应的接收信号计算值。又如，UE还可以直接将原始测量结果中的不可用区域的小区的测量结果过滤掉，即目标测量结果中只包括可用区域的小区的测量结果。
需要说明的是，本申请实施例提供的小区测量方法既适用于UE的服务小区属于所述不可用区域、且RRC层处于连接态或空闲(Idle)态的情况，还适用于UE的服务小区属于所述可用区域、且RRC层处于连接态或空闲态的情况。
即，在一些实施例中，在UE的服务小区属于所述不可用区域、且RRC层处于连接态或空闲态的情况下，对所述原始测量结果进行修改。可以理解地，对于这一场景，通过对原 始测量结果的修改，可以提高UE从不可用区域的小区切换或重选至可用区域的小区的概率，从而保证处于服务区域限制边缘外的UE提供正常服务的连续性；
在一些实施例中，在所述UE的服务小区属于所述可用区域、且RRC层处于连接态或空闲态的情况下，对所述原始测量结果进行修改。可以理解地，对于这一场景，通过对原始测量结果的修改，可以使UE能够积极驻留到可提供正常服务的小区，从而极大地保证处于服务区域限制边缘的UE提供正常服务的概率。
可以理解地，在UE的RRC层处于空闲态的情况下，UE可以根据目标测量结果进行小区重选；在UE的RRC层处于连接态的情况下，UE可以根据目标测量结果生成测量报告，然后将测量报告上报给网络设备，由网络设备根据测量报告将UE切换至合适的小区。
在一些实施例中，处于RRC连接态的UE可以将目标测量结果中满足条件的小区上报给网络设备。例如，将接收信号测量值或者接收信号计算值大于特定门限的小区上报给网络设备，或者将这些值中最大的一个或多个的小区上报给网络设备。
在本申请实施例中，在UE接收到网络设备给配置的可用区域或不可用区域的信息的场景下，UE不是直接根据小区测量得到的原始测量结果进行小区重选或小区切换的，而是先对原始测量结果进行修改，根据修改后得到的目标测量结果进行小区重选或小区切换；如此，通过修改，使得目标测量结果能够增大UE处于该场景下时切换或重选至可用区域的小区的概率，从而提高UE的通信服务性能。
本申请实施例再提供一种小区测量方法，图4为本申请实施例提供的小区测量方法的实现流程示意图，如图4所示，该方法可以包括以下步骤401至步骤404：
步骤401，在UE接收到网络设备下发的用以指示可用区域或不可用区域的TAI列表的场景下，根据该列表确定所述服务小区是否属于所述不可用区域的小区；如果是，执行步骤402；否则，执行步骤403；
可以理解地，如果UE的服务小区处于不可用区域，说明此时的UE处于服务受限状态；如果UE的服务小区处于可用区域，说明此时的UE处于服务未受限状态。所谓服务受限状态是指UE在该服务小区下不能够给用户提供正常服务(即本应享受的服务)。例如，当UE处于不可用区域的小区，除了紧急业务和高优先级用户的业务，UE无法提供正常服务。而UE在服务未受限状态下，可以给用户提供正常服务。
在一些实施例中，UE如果是服务受限状态，其5GMM的状态为：5GMM-REGISTERED.NON-ALLOWED-SERVICE；UE如果处于服务未受限状态，其5GMM的状态为5GMM-REGISTERED.NORMAL-SERVICE。
步骤402，在UE的RRC层处于连接态或空闲态时，对基于小区测量得到的原始测量结果进行修改，得到目标测量结果；其中，所述目标测量结果相比于所述原始测量结果，能够增大所述UE切换或重选至所述可用区域的小区的概率；如此，通过对原始测量结果的修改，可以提高UE从不可用区域的小区切换或重选至可用区域的小区的概率，从而保证处于服务区域限制边缘外的UE提供正常服务的连续性。
步骤403，若UE的RRC层当前处于空闲态，触发服务请求过程，从而使UE的RRC层进入连接态；然后进入步骤404；
步骤404，若UE的RRC层当前处于连接态，对基于小区测量得到的原始测量结果进行修改，得到目标测量结果；其中，所述目标测量结果相比于所述原始测量结果，能够降低所述UE切换至所述不可用区域的小区的概率；如此，通过对原始测量结果的修改，可以使UE能够积极驻留到可提供正常服务的小区，从而极大地保证处于服务区域限制边缘的UE提供正常服务的连续性。
在一些实施例中，RRC层处于空闲态的UE，可以根据目标测量结果进行小区重选。
在一些实施例中，RRC层处于连接态的UE，可以根据目标测量结果进行测量报告的上报，网络根据测量包括将UE切换至合适的小区。
本申请实施例提供一种小区测量方法，图5A为本申请实施例提供的小区测量方法的实 现流程示意图，如图5A所示，其中步骤501和步骤503未示出，该方法可以包括以下步骤501至步骤503：
步骤501，在UE接收到网络设备下发的用以指示可用区域或不可用区域的TAI列表的场景下，确定基于小区测量得到的原始测量结果。
对于UE确定的原始测量结果的类型不做限制，可以是各种类型的值。在一些实施例中，原始测量结果包括以下至少之一：UE基于小区测量得到的邻小区的第一接收信号测量值、UE基于所述第一接收信号测量值计算得到的邻小区的第一接收信号计算值、UE基于小区测量得到的服务小区的第二接收信号测量值、基于所述第二接收信号测量值计算得到的服务小区的第二接收信号计算值。
对于表征第一接收信号测量值和第二接收信号测量值的参数类型不做限制。例如，所述第一接收信号测量值和所述第二接收信号测量值为参数RSRP或RSRQ的值。对于表征第一接收信号计算值和第二接收信号计算值的参数类型也不做限制。例如，所述第一接收信号计算值和所述第二接收信号计算值为参数Srxlev、Squal或Rank的值。
步骤502，UE对原始测量结果的修改操作可以执行以下至少之一，从而得到目标测量结果：(1)减小属于所述不可用区域的邻小区的所述第一接收信号测量值或所述第一接收信号计算值，(2)增大属于所述可用区域的邻小区的所述第一接收信号测量值或所述第一接收信号计算值，(3)在所述UE的服务小区属于不可用区域的小区的情况下，减小所述服务小区的第二接收信号测量值或第二接收信号计算值。
对于步骤502的(1)和(2)，既适用于UE的服务小区为不可用区域的小区的场景，也适用于UE的服务小区为可用区域的小区的场景。
可以理解地，通过步骤502的(1)，即减小属于不可用区域的邻小区的接收信号测量值或计算值；如此，可能会存在以下结果：不可用区域的邻小区的接收信号测量值或计算值较低，未达到网络切换事件的门限；或者，UE在上报测量报告时，使得该测量报告中包括的不可用区域的邻小区的数目减少；从而，无论UE当前的服务小区是可用区域的小区还是不可用区域的小区，均能够减小UE的不可用区域的邻小区被选中的概率，进而尽量避免UE切换或重选至该邻小区。
需要说明的是，在本申请实施例中，对于减小属于不可用区域的邻小区的第一接收信号测量值或第一接收信号计算值的方法不做限定，可以通过诸如减法、乘法或除法等运算的方式来达到减小的目的。比如，小于1的权值与属于不可用区域的邻小区的第一接收信号测量值或第一接收信号计算值相乘，从而达到减小的目的；其中，权值的大小与属于可用区域的服务小区的第二接收信号测量值呈正相关。又如，直接将属于不可用区域的邻小区的第一接收信号测量值或第一接收信号计算值与对应的待减量做减法运算，从而达到减小的目的。
当然，也不限定是正相关的关系，对于可用区域的服务小区的第二接收信号测量值，无论大或小，对应的权值或待减量可以是相同的。
通过步骤502的(2)，即增大属于可用区域的邻小区的接收信号测量值或计算值；如此，可能会存在以下结果：可用区域的邻小区的接收信号测量值或计算值较高，达到触发网络切换事件的门限；或者，UE在上报测量报告时，使得该测量报告中包括的可用区域的邻小区的数目增多；从而，无论UE当前的服务小区是可用区域的小区还是不可用区域的小区，均增大了可用区域的邻小区被选中的概率，进而使UE尽量切换或重选至可用区域的邻小区。
同样地，在本申请实施例中，对于增大可用区域的邻小区的第一接收信号测量值或第一接收信号计算值的方法不做限定，可以通过诸如加法、乘法或除法等运算的方式来达到增大的目的。比如，大于1的权值与可用区域的邻小区的第一接收信号测量值或第一接收信号计算值相乘，从而达到增大的目的；其中，权值的大小与属于不可用区域的服务小区的第二接收信号测量值呈正相关。又如，直接将可用区域的邻小区的第一接收信号测量值或第一接收信号计算值与对应的待增量做加法运算，从而达到增大的目的。
当然，也不限定是正相关的关系，对于不可用区域的服务小区的第二接收信号测量值， 无论大或小，对应的权值或待增量可以是相同的。
通过步骤502的(3)，即在所述UE的服务小区属于不可用区域的小区的情况下，减小属于不可用区域的服务小区的接收信号测量值或计算值；如此，一方面，可以尽可能地使减小后的值满足测量启动条件，从而尽早触发驻留在不可用区域的小区的UE启动小区测量，间接地增大了UE重选至可用区域的小区的概率；另一方面，UE在使用R准则时，能够尽可能地使UE不再驻留在该服务小区，从而间接地增大了UE重选至可用区域的小区的概率。
在一些实施例中，UE还可以在检测到服务小区属于所述不可用区域时，立即启动小区测量，触发RRC层进行小区测量；如此，相比于等待该服务小区的测量值或计算值小于对应的特定门限时才触发小区测量，前者能够使UE尽早地切换或重选到可用区域的小区上。
步骤503，根据所述目标测量结果进行小区重选或小区切换。
可以理解地，在UE的RRC层处于空闲态的情况下，UE可以根据目标测量结果进行小区重选；在UE的RRC层处于连接态的情况下，UE可以根据目标测量结果生成测量报告，然后将测量报告上报给网络，由网络根据测量报告将UE切换至合适的小区。
在一些实施例中，对于UE的服务小区属于所述可用区域、且RRC层处于连接态或空闲态的情况下，对于步骤502中的(1)，所述减小属于所述不可用区域的邻小区的第一接收信号测量值，如图5B所示，可以包括以下步骤502-(1)-1和步骤502-(1)-2：
步骤502-(1)-1，确定所述服务小区的第二接收信号测量值。
在一些实施例中，第二接收信号测量值可以是该服务小区的RSRP或者RSRQ。
步骤502-(1)-2，根据所述第二接收信号测量值，减小属于所述不可用区域的邻小区的第一接收信号测量值或第一接收信号计算值；其中，所述第一接收信号测量值的减小量与所述第二接收信号测量值呈正相关；所述第一接收信号计算值的减小量与所述第二接收信号测量值呈正相关。
可以理解地，所谓正相关是指自变量增长，因变量也跟着增长。在这里，自变量可以为服务小区的第二接收信号测量值，因变量可以为不可用区域的邻小区的第一接收信号测量值或第一接收信号计算值的减小量。也就是说，在UE当前驻留的小区(即服务小区)为可用区域的小区的场景下，属于可用区域的服务小区的第二接收信号测量值(或第二接收信号计算值)越大，相应地，对不可用区域的邻小区的第一接收信号测量值(或第一接收信号计算值)减小的越多。简而言之，在UE当前驻留的小区为可用区域的小区、且信号强度较强的情况下，为了使UE能够稳定地驻留在该小区，可以通过减小不可用区域的邻小区的第一接收信号测量值或计算值的手段，进一步减少上报的测量报告中的不可用区域的邻小区数目或者不可用区域的邻小区的接收信号测量值或计算值较低，未达到网络切换事件的门限，从而降低网络将UE切换或重选到不可用区域的小区的概率，使得UE尽可能地驻留在可用区域的小区并保持业务的连续性。
进一步地，在一些实施例中，对于步骤502-(1)-2中，减小属于所述不可用区域的邻小区的第一接收信号测量值包括：根据第一映射关系，确定与所述第二接收信号测量值对应的第一待减量；其中，在所述第一映射关系中，所述第二接收信号测量值与所述第一待减量呈正相关；将属于所述不可用区域的邻小区的第一接收信号测量值降低所述第一待减量；
对于步骤502-(1)-2中，减小属于所述不可用区域的邻小区的第一接收信号计算值包括：根据所述第二接收信号测量值，确定所述服务小区的第二接收信号计算值；根据第二映射关系，确定与所述第二接收信号计算值对应的第二待减量；其中，在所述第二映射关系中，所述第二接收信号计算值与所述第二待减量呈正相关；将属于所述不可用区域的邻小区的第一接收信号计算值降低所述第二待减量。
以减小属于所述不可用区域的邻小区的第一接收信号测量值为例，假设第一接收信号测量值为参数RSRP的值，属于可用区域的服务小区的RSRP与第一待减量的映射关系如表1：
表1
服务小区的RSRP(可用区域) 邻小区的第一待减量(不可用区域)
-80dbm 30dbm
-81dbm 29dbm
-82dbm 28dbm
… …
-109dbm 1dbm
从表1中可以看出，可用区域的服务小区的RSRP越大，不可用区域的邻小区的第一待减量也越大，相应地，修改时，不可用区域的邻小区的第一接收信号测量值减小的也越多。例如，服务小区的RSRP为-80dbm，不可用区域的邻小区的实际测量的RSRP为-78dbm，根据表1对应的第一待减量为30dbm，那么对该邻小区的RSRP减小30dbm后为-108dbm，将该值作为目标测量结果之一。
对于UE的服务小区属于所述不可用区域、且RRC层处于连接态或空闲态的情况下，在一些实施例中，对于步骤502中的(2)中，所述减小属于所述不可用区域的邻小区的第一接收信号测量值，如图5C所示，可以包括以下步骤502-(2)-1和步骤502-(2)-1：
步骤502-(2)-1，确定所述服务小区的第二接收信号测量值。
在一些实施例中，第二接收信号测量值可以是该服务小区的RSRP或者RSRQ。
步骤502-(2)-2，根据所述第二接收信号测量值，增大属于所述可用区域的邻小区的第一接收信号测量值或第一接收信号计算值；
其中，所述第一接收信号测量值的增大量与所述第二接收信号测量值呈正相关；所述第一接收信号计算值的增大量与所述第二接收信号测量值呈正相关。
可以理解地，所谓正相关是指自变量增长，因变量也跟着增长。在这里，自变量可以为属于不可用区域的服务小区的第二接收信号测量值，因变量可以为属于可用区域的邻小区的第一接收信号测量值或第一接收信号计算值的增大量。也就是说，在UE当前驻留的小区(即服务小区)为不可用区域的小区的场景下，属于不可用区域的服务小区的第二接收信号测量值(或第二接收信号计算值)越大，相应地，对可用区域的邻小区的第一接收信号测量值(或第一接收限号计算值)增大的越多。简而言之，在UE当前驻留的小区为不可用区域的小区、且该小区的信号较强的情况下，为了使UE能够更加容易地切换或重选至可用区域的邻小区，可以通过增加可用区域的邻小区的第一接收信号测量值或计算值的技术手段；如此，若此时UE处于服务区域限制边缘，这将使UE更加容易地切换或重选到可用区域的小区。
进一步地，在一些实施例中，对于步骤502-(2)-2中，增大属于可用区域的邻小区的第一接收信号测量值包括：根据第三映射关系，确定与所述第二接收信号测量值对应的第一待增量；其中，在所述第三映射关系中，所述第二接收信号测量值与所述第一待增量呈正相关；将属于所述可用区域的邻小区的第一接收信号测量值增加所述第一待增量；
对于步骤502-(2)-2中，增大可用区域的邻小区的第一接收信号计算值包括：根据所述第二接收信号测量值，确定所述服务小区的第二接收信号计算值；根据第四映射关系，确定与所述第二接收信号计算值对应的第二待增量；其中，在所述第四映射关系中，所述第二接收信号计算值与所述第二待增量呈正相关；将属于所述可用区域的邻小区的第一接收信号计算值增加所述第二待增量。
以增大属于可用区域的邻小区的第一接收信号测量值为例，假设第一接收信号测量值为参数RSRP的值，属于不可用区域的服务小区的RSRP与第一待增量的映射关系如表2所示。
从表2中可以看出，不可用区域的服务小区的RSRP越大，可用区域的邻小区的第一待增量也越大，相应地，修改时，可用区域的邻小区的第一接收信号测量值增加的也越多。例如，服务小区的RSRP为-80dbm，可用区域的邻小区的实际测量的RSRP为-108dbm，根据表2对应的第一待增量为30dbm，那么对该邻小区的RSRP增大30dbm后为-78dbm，将该值作为目标测量结果之一。
表2
服务小区的RSRP(不可用区域) 邻小区的第一待增量(可用区域)
-109dbm 1dbm
-108dbm 2dbm
-107dbm 3dbm
… …
-80dbm 30dbm
在一些实施例中，在所述UE从属于所述不可用区域的服务小区重选至属于可用区域的目标邻小区的情况下，将所述目标邻小区的作为已重选的小区，将所述已重选的小区的小区信息保存至所述UE中，以便所述UE在开机选网时，优先驻留至所述目标邻小区。可以理解地，UE中保存了重选过的小区信息，这样，UE在下次开机选网时，将该小区优先级提高，以便快速驻留在该小区，从而为用户提供正常服务。
需要说明的是，上述应用在服务区域限制场景下的方法，仍然适用于接入限制场景下的小区重选方案。即上述适用于UE的服务小区为不可用区域的小区，且RRC层处于空闲态的方法，也适用于接入限制场景下的小区重选方案。即，在一些实施例中，在UE接收到禁止向服务小区发起接入的信息的情况下，或者，在所述UE向所述服务小区发起接入后接收到拒绝接入的信息的情况下，对所述服务小区的原始测量结果执行的修改操作如同上述方法中对属于所述不可用区域的邻小区或属于所述不可用区域的服务小区的原始测量结果的修改操作；即，在UE接收到禁止向服务小区发起接入的信息的情况下，或者，在所述UE向所述服务小区发起接入后接收到拒绝接入的信息的情况下，对所述服务小区的原始测量结果执行的修改操作包括以下至少之一：
减小所述服务小区的接收信号测量值；
减小所述服务小区的接收信号计算值；
其中，减小量可以是预设值，也可以根据邻小区的接收信号测量值或接收信号计算值的大小，确定对应的减小量，基于该确定的减小量减小所述服务小区的接收信号测量值或接收信号计算值；其中，所述服务小区的接收信号测量值的减小量与邻小区的接收信号测量值呈正相关；所述服务小区的接收信号计算值的减小量与邻小区的接收信号计算值呈正相关。如此，在接入限制场景下，能够使得UE尽早触发小区重选或小区切换，从而尽早驻留在接入不受限制的小区，进而提高UE的业务连续性。
在一些实施例中，在UE接收到禁止向服务小区发起接入的信息的情况下，或者，在所述UE向所述服务小区发起接入后接收到拒绝接入的信息的情况下，对邻小区的原始测量结果执行的修改操作如同上述方法中对属于所述可用区域的邻小区的原始测量结果的修改操作；即，在UE接收到禁止向服务小区发起接入的信息的情况下，或者，在所述UE向所述服务小区发起接入后接收到拒绝接入的信息的情况下，对邻小区的原始测量结果执行的修改操作包括以下至少之一：
增大所述邻小区的接收信号测量值；
增大所述邻小区的接收信号计算值；
其中，增大量可以是预设值，也可以是根据服务小区的接收信号测量值或接收信号计算值的大小，确定对应的增大量，基于该确定的增大量增大邻小区的接收信号测量值或接收信号计算值；其中，邻小区的接收信号测量值的增大量与服务小区的接收信号测量值呈正相关；邻小区的接收信号计算值的增大量与服务小区的接收信号计算值呈正相关。如此，在接入限制场景下，能够使得UE尽早触发小区重选或小区切换，从而尽早驻留在接入不受限制的小区，进而提高UE的业务连续性。
下面将说明本申请实施例在一个实际的应用场景中的示例性应用。
针对服务区域限制场景中UE可能无法获取正常服务的缺点，在本申请实施例中，旨在提出一种方法使得UE处于服务区域限制边缘时，能够快速重选或切换到可用区域以恢复正常服务，或者保持UE尽量驻留在可用区域小区来保证正常服务的机制：即对于上述场景一， 当UE处于可用区域边缘的小区时，通过调整重选准则和测量报告的信号值，尽量减少UE重选或切换到不可用区域小区的概率。对于上述场景二，当UE处于不可用区域边缘的小区时，通过调整重选准则和测量报告的信号值，触发UE重选或切换到可用区域的小区，从而能够提供正常服务。
图6描述了UE成功注册到网络后，收到网络下发的服务区域列表(Service area list)后的处理过程，如图6所示，包括以下步骤601至步骤605：
步骤601，UE成功注册到网络，网络下发服务区域列表；
步骤602，非接入层(Non-Access-Srtatum，NAS)将该列表中的可用区域或不可用区域TAI列表通知给接入层(Access-Srtatum，AS)；
步骤603，NAS判断当前是否处于可用区域的小区；如果是，执行步骤604；否则，执行步骤605；
步骤604，NAS进入5GMM-REGISTERED.NORMAL-SERVICE状态；
步骤605，NAS进入5GMM-REGISTERED.NON-ALLOWED-SERVICE状态。
图7描述了当UE收到高层发起业务请求，UE处于服务区域限制边缘时提供正常服务保证和恢复机制。如图7所示，在本申请实施例中，UE收到高层的业务请求，根据NAS当前状态进行判断：
如果NAS处于5GMM-REGISTERED.NORMAL-SERVICE状态：
(1)若RRC层当前处于空闲态，则触发服务请求(service request)过程，使RRC层进入连接态。
(2)若RRC层当前处于连接态，则通知RRC层尽量保持在可用区域的TAI的小区，并正常发起业务过程。当RRC层收到尽量保持在可用区域的TAI的小区的指示，RRC层将测量到的邻小区进行筛选，如果属于不可用区域TAI的小区，则将其RSRP进行加权处理(加权系数可采用1.2，例如邻小区的RSRP为-80dbm，则加权后的RSRP为-80*1.2＝-96dbm)，若此时UE处于服务区域限制边缘，这将使UE尽可能得驻留在可用区域TAI的小区并保持业务的持续性。
如果NAS处于5GMM-REGISTERED.NON-ALLOWED-SERVICE状态：
由于在此状态无法进行正常的业务，NAS将高层的业务挂起，并通知RRC层尝试进行受限服务区域限制的小区变换。
(1)若RRC层处于空闲态，RRC层进行受限服务区域限制下的小区重选，RRC层将测量到的邻小区进行筛选，如果测量到的邻小区属于不可用区域TAI的小区，则将其RSRP进行加权处理(加权系数可采用1.2，例如邻小区的RSRP为-80dbm，则加权后的RSRP为-80*1.2＝-96dbm)，若此时UE处于服务区域限制边缘，这将更加容易地开启测量和重选到可用区域TAI的小区。如果新驻留的小区属于可用区域TAI的小区，则NAS建立RRC层连接并处理之前挂起的业务请求。
(2)若RRC层处于连接态，RRC层将测量到的邻小区进行筛选，如果测量到的邻小区属于可用区域TAI的小区，则将其RSRP进行加权处理(加权系数可采用0.8，例如邻小区的RSRP为-110dbm，则加权后的RSRP为-110*0.8＝-88dbm)，若此时UE处于服务区域限制边缘，这将更容易触发网络将UE切换到可用区域TAI的小区。如果切换后的小区属于可用区域TAI的小区，RRC层通知NAS新小区信息，NAS在新小区上恢复之前挂起的业务请求。
在一些实施例中，在空闲态，UE驻留在不可用区域小区时检测到可用的邻小区，立即启动邻小区的测量，从而进行小区重选；若重选成功，将重选过的小区信息记录下来，在下次开机选网的时候，将该小区优先级提高以便快速驻留并提供正常服务。
在一些实施例中，鉴于本方案的通用性和安全性，该方案还可以应用于接入限制场景下的小区重选方案。
在本申请实施例中，所有实现只需要非接入层和接入层协同工作即可完成，软件实现复杂度低，但是带来的性能改善却非常明显，例如表3所示。
