  • This application relates to, but is not limited to, network sharing technologies, such as a method and device for determining inter-frequency neighboring cells.
  • Network sharing refers to a practice in which different operators jointly bear the high cost of mobile network deployment during the network deployment stage. Network sharing can greatly improve network utilization. When network sharing is deployed, due to the shared area, shared network transformation or deployment rhythm, etc., a boundary area between shared and non-shared networks is bound to appear. In this case, for a User Equipment (UE) that is not on the network frequency of the operator, when moving from a shared network to a non-shared network, the UE must switch to the network of the operator frequency point.

Description

一种确定异频临区的方法及装置
本申请要求在2019年07月09日提交中国专利局、申请号为201910613787.1的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及但不限于网络共享技术，例如一种确定异频邻区的方法及装置。
背景技术
网络共享，是指不同运营商之间在网络部署阶段共同承担高昂的移动网络部署费用的一种做法，通过网络共享可以极大地提高网络的利用率。在网络共享部署时，由于共享的区域范围、共享网络改造或部署节奏等原因，势必会出现共享网络与非共享网络之间的边界区域。在这种情况下，对于非本运营商网络频点的用户终端设备(User Equipment，UE)，在从共享网络向非共享网络移动时，由于该UE必须要切换到所属运营商频点的网络中，即不能进行同频切换，必须要进行异频或者异系统切换(因为异系统切换也是一种异频切换，因此，本文将异频或者异系统切换简称为异频切换，如不特殊说明，都是指异频或者异系统切换)。
网络融合是一种趋势，从一开始的两家运营商网络共享到四、五家甚至更多的运营商网络共享，共享网络的规模和复杂度越来越高。在网络共享的边界区域(共享网络和非共享网络的边界区域)，不同归属公共陆地移动网络(PLMN，Public Land Mobile Network)的用户(即不同运营商的用户)可以做切换的异频频点不同，每家运营商都有在边界区域切换到归属网络的需求，这些切换的频点数量总和会很多，可能会超过终端的支持能力。
比如，在第三代合作伙伴计划(3GPP，3rd Generation Partnership Project) 相关协议的约束下，对于频分双工(FDD，Frequency Division Duplexing)通用路面无线接入(UTRA，Universal Terrestrial Radio Access)网络情况，UE一般最多支持2个系统内的异频频点的测量，时分双工(TDD，Time Division Duplex)UTRA网络最多支持3个异频频点；对演进型通用路面无线接入(Evolved Universal Terrestrial Radio Access，E-UTRA)网络，频分双工演进型通用路面无线接入(Frequency Division Duplexing Evolved Universal Terrestrial Radio Access，FDD E-UTRA)系统内一般可以支持3个异频频点测量(与时分双工演进型通用路面无线接入(Time Division Duplex Evolved Universal Terrestrial Radio Access，TDD E-UTRA)相同)，更多的频点数目和终端能力相关，支持测量能力扩展的UE可以支持8个频点的系统内测量。但是，用户的终端能力也是有限的，很多终端是按照3GPP的最低要求实现的，随着共享网络的复杂度越来越高，频点数也会受限；对于第五代移动通信技术(5th Generation Wireless Systems，5G)网络情况，不同的网络架构(如非独立组网(Non Independent Network，NSA)和独立组网(Non independent Network，SA)支持的最低频点数不一样，比如：NSA网络，系统内一般支持7个新无线接口(NR，New Radio)异频频点测量；再如：SA网络，系统内一般支持7个NR异频频点测量。同样，5G新空口(5th Generation Wireless Systems New Radio，5G NR)终端的频点测量能力也是有限的，一些终端是按照协议的最低要求来实现，在复杂的组网中，往往遇到频点个数不够的问题。
在共享网络边界区域(即共享网络区域与非共享网络区域的边界处，也可称为共享载波边界区域)，配置的异频邻区和异系统邻区(本文将异频和异系统邻区简称为异频邻区，如不特殊说明，都是指异频或者异系统邻区)会非常的多，会配置很多到多个PLMN归属网络的邻区，终端会测量很多无效的邻区 (比如不是此终端归属网络的邻区)。在UTRA网络中，因为每个小区给单个终端发送的测量控制消息中包含的邻区数量是有限制的，最多32个，这样就会导致单个终端可能收到的有效邻区会非常的少，甚至可能收不到归属网络的邻区，终端就无法切换回到归属网络，导致掉话。在E-UTRA和5G NR中，会给UE指定测量的频点，如果把所有的异频频点都发送给UE，也会超过UE的测量能力，就算没有超过测量能力，也会导致UE做很多无效测量(比如，测量报告是针对其他UE的归属网络的，演进节点(Evolved NodeB，eNodeB)收到测量报告后，判决此邻区没有授权，不能切换)，无效测量浪费了UE的测量时隙(Gap)，消耗了UE的性能。

为使本申请的目的、技术方案和优点清楚明白，下文中将结合附图对本申请的实施例进行说明。
图1为本申请第一实施例提供的共享载波边界区域的异频切换示意图，如图1所示，运营商A即图中的A网络，运营商B即图中的B网络，运营商C即图中的C网络，运营商A、运营商B和运营商C在区域X即图中的共享区域部署FDD UTRA网络共享，在其他区域单独建网。假设运营商A拥有频点F1，频点F2和频点F3，运营商B拥有频点F4，频点F5和频点F6，运营商C拥有频点F7，频点F8和频点F9。在共享区域内，运营商A，运营商B和运营商C可以使用运营商A的频点F1，频点F2和频点F3。在非共享区域，运营商A，运营商B，运营商C各自独立建设/部署网络，运营商A只能使用频点F1，频点F2和频点F3，运营商B只能使用频点F4，频点F5和频点F6，运营商C只能使用频点F7，频点F8和频点F9。在边界共享区域内运营商A小区1(CELL1)(F1载频)，原有规划异频切换邻区为CELL2(F2载频)，CELL3(F3载频)，正好是2个异频频点(还可以配置更多的F2载频和F3载频邻区，最多可以达到32个)。网络共享后，运营商B的用户和运营商C的用户也可以接入小区CELL1，因为CELL1在边界，运营商B的用户和运营商C的用户有切换到自身归属网络的需求，所以CELL1至少需要添加非共享网络CELL4(F4载频)和CELL5(F7载频)为异频邻区，这样CELL1的异频邻区信息包括4个频点的异频邻区(频点F2，频点F3，频点F4，频点F7的邻区)。但是按照3GPP协议相关规定，FDD UTRA网络UE只能测量2个异频频点，所以控制器只会选择其中的2个异频频点邻区在测量控制消息中发送，比如，控制器选择的是F2和F4，那么将出现以下问题：
1、运营商A的用户的异频频点只有F2，缺少了F3，虽然F4可以测量，但是不能切换，属于无效测量，所以运营商A的用户不能切换到F3载频，导致切 换频点不能达到最大2个。
2、运营商C的用户无法切换到归属网络，因为测量控制消息中没有携带F7频点的邻区。
这种情况会导致运营商A，运营商B，运营商C的异频频点和异频邻区数量都减少(极端情况运营商C的用户不能切换到归属网络)，大大降低了异频切换成功率，增加了掉话率。
图9为本申请第三实施例提供的共享载波边界区域的异频切换示意图，如图10所示，运营商A即图中的A网络，运营商B即图中的B网络，运营商C即图中的C网络，运营商D即图中的D网络和运营商E即图中的E网络，运营商A、运营商B、运营商C、运营商D和运营商E在区域X即图中的共享区域部署FDD E-UTRA或者5G NR网络共享，在其他区域单独建网。假设运营商A拥有频点F1，频点F2，频点F3和频点F4，运营商B拥有频点F5，频点F6，频点F7和频点F8，运营商C拥有频点F9，频点F10，频点F11和频点F12，运营商D拥有频点F13，频点F14，频点F15和频点F16，运营商E拥有频点F17，频点F18，频点F19和频点F20。在共享区域内，运营商A，运营商B，运营商C，运营商D，运营商E可以使用运营商A的频点F1，频点F2，频点F3，频点F4。在非共享区域，运营商A，运营商B，运营商C，运营商D，运营商E各自独立建设/部署网络，运营商A只能使用频点F1，频点F2，频点F3，频点F4，运营商B只能使用频点F5，频点F6，频点F7，频点F8，运营商C只能使用频点F9，频点F10，频点F11，频点F12，运营商D只能使用频点F13，频点F14，频点F15，频点F16，运营商E只能使用频点F17，频点F18，频点F19，频点F20。在边界共享区域内运营商A小区1(CELL1)(F1载频)，原有规划异频切换频点为频点F2，频点F3，频点F4，不存在频点浪费的情况，也不存在无效测量。网络共享后，运营商B，运营商C，运营商D，运营商E用户也可以接入CELL1，因为CELL1在边界，运营商B，运营商C，运营商D，运营商E的用户有切换到各自归属网络的需求，所以小区CELL1需要添加非共享网络频点F5，频点F6，频点F9，频点F10，频点F13，频点F14，频点F17，频点F18的邻区为异频邻区，这样CELL1的异频邻区信息包括11个频点的异频邻区(频点F2，频点F3，频点F4，频点F5，频点F6，频点F9，频点F10，频点F13，频点F14，频点F17，频点F18)。按照3GPP协议相关规定，FDD E-UTRA 网络UE一般可以测量3个系统内异频频点(支持测量能力扩展的UE可以测量8个)，5G NR一般可以测量7个系统内异频频点，虽然这些都是最低要求，实际实现时大部分UE是按照最低的协议要求实现的，可测量的异频频点个数较少，而且，就算终端能力较强，测量频点没有受限，但是对于每个归属网络的UE来说，测量11个频点，包含了很多无效频点，浪费了UE的测量GAP，增加了空口负荷。而且携带过多的测量频点，如果超过了UE的测量能力，还会导致终端问题。
为了解决上述问题，本申请提出一种确定异频邻区的方法，如图2所示，包括：
步骤210：获取进入共享网络边界区域的用户终端归属网络的网络标识。
在一种示例性实例中，本步骤之前还包括：用户终端进入共享网络边界区域，用户终端进入共享网络边界区域包括：用户终端处于共享网络边界区域(也可称为共享载波边界区域)，并接入或者切换到共享网络边界区域的一个边界小区(可以称为目标边界小区)，且该边界小区是主服务小区。
在一种示例性实例中，在UTRA网络中，主服务小区为激活集中的主小区；在E-UTRA和5G NR网络中，主服务小区为主小区(PCell，Primary Cell)。
在一种示例性实例中，用户终端归属网络的网络标识包括：用户终端归属的PLMN的公共陆地移动网络标识(Public Land Mobile Network Identity Document，PLMN ID)，本申请中可以称为区分公共陆地移动网络标识(Selected Public Land Mobile Network Identity Document，Selected-PLMN ID)。
在一种示例性实例中，Selected-PLMN ID为用户终端的归属网络或者等效网络的PLMN ID。
每个PLMN网络由PLMN ID确定，PLMN ID包括移动设备国家代码(Mobile Country Code，MCC)和移动设备网络代码(Mobile Network Code，MNC)。
步骤220：根据网络标识对应的可执行异频切换的异频频点的配置信息，对用户终端可切换的邻区信息进行处理，得到包括属于所述异频频点的邻区的异频邻区信息。
在一种示例性实例中，步骤220之前，还包括：
对共享网络边界区域的每个主服务小区下的每个运营商PLMN分配0到规定数目的异频频点，从而形成所有可执行异频切换的异频频点的配置信息。
在一种示例性实例中，针对UTRA，规定数目为第一规定数目，如2个的异频频点；针对E-UTRA或5G NR，规定数目为第二规定数目，如16个异频频点。
这些异频频点是归属于该PLMN的用户终端能够在该主服务小区进行异频切换的目标频点。例如，针对每一个PLMN ID下的UE，除了这些目标频点，其他频点都不能用于切换。
在一种示例性实例中，步骤220之前，还包括：
根据归属每个运营商的用户终端实际可以执行异频切换的异频邻区，配置共享网络边界区域的每个小区的异频邻区信息作为用户终端可切换的邻区信息。
共享网络边界区域的每个小区的异频邻区信息是根据实际情况和规划配置的可切换的邻区信息确定的，此时并不用考虑频点数量的限制。比如，对于UTRA网络，可以配置超过第三规定数目(如32个异频邻区)和超过第一规定数目(如2个异频频点的邻区信息)，每个小区可以通过规划尽可能多的配置异频邻区。再如：对于E-UTRA或5G NR网络，原则上也没有频点个数限制和邻区个数限制。在一实施例中，无论是UTRA网络、E-UTRA网络还是5G NR网络，在配置异频邻区时，因为容量的原因会做一些数量上的限制。
在一种示例性实例中，对于UTRA网络，用户终端可切换的邻区信息，是指激活集内的所有小区合并后的邻区信息。因为激活集内的所有小区的邻区都是终端可以切换的邻区，因此，会先将激活集中的小区的邻区进行合并，以删除重复的异频邻区。合并后的邻区的数目可能会超过第三规定数目，如32个，异频频点数目可能会超过第一规定数目，如2个。
在一种示例性实例中，步骤220可以包括：
根据用户终端归属PLMN的PLMN ID，在归属的PLMN的可执行异频切换的异频频点的配置信息中，查找到用户终端接入或切换到的边界小区对应的异频频点；根据查找到的异频频点对用户终端可切换的邻区信息包括的所有的异频频点和异频邻区进行过滤，保留属于查找到的异频频点的邻区，删除不属于 查找到的异频频点的邻区。
在一种示例性实例中，对于UTRA网络，过滤后的异频频点不会超过第一规定数目，如2个；对于E-UTRA或5G NR网络，过滤后的异频频点不会超过第二规定数目，如16个。
在一种示例性实例中，对于UTRA网络，如果过滤后的异频邻区中的邻区个数大于第三规定数目(如32个)的情况下，所述方法还包括：根据优先级对过滤后的异频邻区中的邻区进行排序，从优先级级别最高开始，选择第三规定数目(如32个邻区)作为过滤后的异频邻区，即选择优先级级别高的前32个邻区作为过滤后的异频邻区。在一种示例性实例中，对于优先级相同的邻区，按照配置顺序从前往后进行排序即可。
通过本申请提供的确定异频邻区的方法，对于UTRA网络，确定出的异频邻区信息中，异频邻区的数目不会超过第一规定数目，如32个，并且异频频点的数目不会超过第二规定数目，如2个；对于E-UTRA或5G NR网络，确定出的异频邻区信息中，异频频点个数不超过第三规定数目，如16个，本申请最大化利用了异频频点和异频邻区，减少了UE的测量GAP，提高了异频切换成功率，降低了掉话率。
在一种示例性实例中，所述方法还包括：通过测量控制消息将得到的异频邻区信息发送给用户终端，以在合适时机触发用户终端进行异频邻区的测量。

下面结合具体实施例对本申请进行描述。
第一实施例，以UTRA网络为例，假设由无线网络控制器(RNC，Radio Network Controller)实现对邻区信息的确定，第一实施例中，以图1所示的共享载波边界区域的异频切换示意图为例，共享载波由运营商A提供，另外两家运营商即运营商B和运营商C，可以在共享载波区域使用运营商A的载波，而在非共享载波区域不能使用运营商A的载波。确定邻区信息的方法包括：
首先，RNC根据实际情况和规划配置每个小区的可切换的异频邻区信息；以及，RNC配置共享载波边界区域小区的区分PLMN ID的异频邻区可执行异频切换的异频频点。
在一种示例性实例中，可以预先根据每个运营商UE实际可以执行异频切换的异频邻区进行配置，此时不用考虑频点数量限制，如图4所示，共享区域内边界小区F1，F2，F3均配置了超过2个频点的异频邻区，图4中，双向箭头表示双向切换关系，单项箭头表示单项切换关系。
在一种示例性实例中，结合图1的描述，以CELL1为例，CELL1下配置的可执行异频切换的异频频点包括：网络A可切换的频点：频点F2，频点F3；网络B可切换的频点：频点F2，频点F4；网络C可切换的频点：频点F2，频点F7。
在一种示例性实例中，每个PLMN ID是实际共享载波区域使用的PLMN ID，在第一实施例中，共享载波由运营商A提供，运营商B和运营商C在共享 载波区域可以接入或者使用运营商A的载波，在非共享区域则不能使用。
接着，当一个归属PLMN的用户终端初始接入到共享载波区域的一边界小区，通过硬切换或者软切换到该边界小区且该边界小区是为主服务小区时，启动本申请确定异频邻区的方法。
在一种示例性实例中，初始接入共享载波区域的一边界小区，可以是通过如无线资源控制(Radio Resource Control，RRC)连接请求以及小区更新(CELL UPDATE)请求接入到该边界小区，并且该边界小区是激活集中的主服务小区。通过硬切换或者软切换到该边界小区并且该边界小区为主服务小区包括：用户终端从其他小区硬切换到该边界小区，并且该边界小区是主服务小区，以及通过激活集更新流程添加该边界小区为激活集中的小区，并且是激活集中的主服务小区。
然后，将激活集中的所有小区的异频邻区合并，将多个小区的异频邻区表组成第一列表，假设合并后得到的第一列表称为该UE的小区级的异频邻区列表。
在一种示例性实例中，由于激活集中的小区可能会有重复的邻区，因此在合并得到第一列表过程中会删除重复的邻区。在合并得到的第一列表中，异频邻区数目可以超过32个，异频频点数目可以超过2个。
之后，根据区分PLMN ID的异频邻区可执行异频切换的异频频点的配置信息，对合并得到的第一列表进行过滤，删除不属于异频频点配置信息中的异频频点的邻区，以形成第二列表。
第二列表可以称为该UE的UE级的异频邻区列表。第二列表中的异频频点数目不会超过2个，但是，第二列表中的异频邻区数目可以超过32个。
结合图1所示的共享载波边界区域的异频切换示意图，图5(a)为本申请第一实施例提供的网络A的用户终端的第二列表的邻区关系示意图，图5(b)为本申请第一实施例提供的网络B的用户终端的第二列表的邻区关系示意图，图5(c)为本申请第一实施例提供的网络C的用户终端的第二列表的邻区关系示意图。
在一种示例性实例中，如果第二列表中的异频邻区数目超过了32个，根据每个异频邻区的优先级和配置顺序对第二列表中的异频邻区进行排序，优先级级别高的排在前面，优先级级别相同的按照配置顺序排序，配置在前面的排序 靠前，删除第二列表中排在前面的32个异频邻区之后的异频邻区信息。
最后，RNC会将处理后的异频邻区信息(即第二列表通过测量控制消息)发送给该UE，以在合适时机触发UE进行异频邻区的测量。
第二实施例，以UTRA网络为例，假设由RNC实现对邻区信息的确定，第二实施例中，以图6所示的共享载波边界区域的异频切换示意图为例，共享载波由运营商A和运营商B提供，在共享载波区域，运营商A的用户可以使用运营商B的载波，运营商B的用户可以使用运营商A的载波，运营商C的用户可以使用运营商A和运营商B的载波，而在非共享载波区域运营商A，B，C只能使用自己的载波。确定邻区信息的方法包括：
首先，RNC根据实际情况和规划配置每个小区的可切换的异频邻区信息；以及，RNC配置共享载波边界区域小区的区分PLMN ID的异频邻区可执行异频切换的异频频点。
在一种示例性实例中，可以预先根据每个运营商UE实际可以执行异频切换的异频邻区进行配置，此时不用考虑频点数量限制，如图7所示，共享区域边界小区F1，F2，F3，F4，F5，F6均配置了超过2个频点的异频邻区，图7中，双向箭头表示双向切换关系，单项箭头表示单项切换关系。
在一种示例性实例中，结合图6，以CELL1为例，CELL1下配置的可执行异频切换的异频频点包括：网络A可切换的频点：频点F2，频点F3；网络B可切换的频点：频点F2，频点F4；网络C可切换的频点：频点F2，频点F7。
本实施例中的运营商A，运营商B，运营商C的用户在共享区域边界可以执行异频切换到归属的PLMN网络。每个PLMN网络是实际共享载波区域使用的PLMN网络，第二实施例中，共享载波由运营商A和运营商B提供，在共享载波区域，运营商A的用户可以使用运营商B的载波，运营商B可以使用运营商A的载波，运营商C可以使用运营商A和B的载波，在非共享载波区域运营商A，运营商B，运营商C只能使用自己的载波。
接着，当一个归属PLMN的用户终端初始接入到共享载波区域的一边界小区，通过硬切换或者软切换到该边界小区且该边界小区是为主服务小区时，启动本申请确定异频邻区的方法。
在一种示例性实例中，初始接入共享载波区域的一边界小区，可以是通过 RRC连接请求以及CELL UPDATE请求接入到该边界小区，并且该边界小区是激活集中的主服务小区。在一实施例中，通过硬切换或者软切换到该边界小区并且该边界小区为主服务小区包括：用户终端从其他小区硬切换到该边界小区，并且该边界小区是主服务小区，以及通过激活集更新流程添加该边界小区为激活集中的小区，并且是激活集中的主服务小区。
然后，将激活集中的所有小区的异频邻区合并，将多个小区的异频邻区表组成第一列表，假设合并后得到的第一列表称为该UE的小区级的异频邻区列表。
在一种示例性实例中，由于激活集中的小区可能会有重复的邻区，因此在合并得到第一列表过程中会删除重复的邻区。在合并得到的第一列表中，异频邻区数目可以超过32个，异频频点数目可以超过2个。
之后，根据区分PLMN ID的异频邻区可执行异频切换的异频频点配置信息，对合并得到的第一列表进行过滤，删除不属于异频频点配置信息中的异频频点的邻区，以形成第二列表。
第二列表可以称为该UE的UE级的异频邻区列表。第二列表中的异频频点数目不会超过2个，但是，第二列表中的异频邻区数目可以超过32个。
结合图6所示的共享载波边界区域的异频切换示意图，图8(a)为本申请第二实施例提供的网络A的用户终端的第二列表的邻区关系示意图，图8(b)为本申请第二实施例提供的网络B的用户终端的第二列表的邻区关系示意图，图8(c)为本申请第二实施例提供的网络C的用户终端的第二列表的邻区关系示意图。
在一种示例性实例中，如果第二列表中的异频邻区数目超过了32个，根据每个异频邻区的优先级和配置顺序对第二列表中的异频邻区进行排序，优先级级别高的排在前面，优先级级别相同的按照配置顺序排序，配置在前面的排序靠前，删除第二列表中排在前面的32个异频邻区之后的异频邻区信息。
最后，RNC会将处理后的异频邻区信息(即第二列表通过测量控制消息)发送给该UE，以在合适时机触发UE进行异频邻区的测量。
第三实施例，以E-UTRA或者5G NR网络为例，假设由演进基站(Evolved Nodeb，eNodeb)或者下一代基站(Generation Nodeb，gNodeb)实现对邻区信息的确定，第三实施例中，以图9所示的共享载波边界区域的异频切换示意图 为例，共享载波由运营商A提供，另外四家运营商即运营商B、运营商C、运营商D和运营商E，可以在共享载波区域使用运营商A的载波，而在非共享载波区域不能使用运营商A的载波。确定邻区信息的方法包括：
首先，eNodeb或者gNodeb根据实际情况和规划配置每个小区的可切换的异频邻区信息；以及，eNodeb或者gNodeb配置共享载波边界区域小区的区分PLMN ID的异频邻区可执行异频切换的异频频点。
在一种示例性实例中，可以预先根据每个运营商UE实际可以执行异频切换的异频邻区进行配置，此时不用考虑频点数量限制，如图10所示，共享区域内边界小区F1，F2，F3，F4均配置11个频点的异频邻区，图10中，双向箭头表示双向切换关系，单项箭头表示单项切换关系。
在一种示例性实例中，结合图9，以CELL1为例，CELL1下配置的可执行异频切换的异频频点包括：网络A可切换的频点：频点F2，频点F3，频点F4；网络B可切换的频点：频点F2，频点F5，频点F6；网络C可切换的频点：频点F2，频点F9，频点F10；网络D可切换的频点：频点F2，频点F13，频点F14；网络E可切换的频点：频点F2，频点F17，频点F18。
本实施例中，每个PLMN ID是实际共享载波区域使用的PLMN ID，第三实施例中，共享载波由运营商A提供，另外4家运营商即运营商B，运营商C，运营商D，运营商E在共享载波区域可以接入或者使用运营商A的载波，在非共享区域不能使用而只能使用自己的载波。
接着，当一个归属PLMN用户终端初始接入到共享载波区域的一边界小区，通过切换到该边界小区时，启动本申请确定异频邻区的方法。
在一种示例性实例中，初始接入共享载波区域的一边界小区，可以是通过RRC连接请求以及RRC重建立请求接入到该边界小区。，通过切换到该边界小区包括：用户终端从其他小区切换到该边界小区，并且此小区是主服务小区。
在一种示例性实例中，该边界小区针对该UE的PLMN的异频频点列表为该UE的小区级的异频频点列表。
结合图9所示的共享载波边界区域的异频切换示意图，图11(a)为本申请第三实施例提供的网络A的用户终端的第二列表的邻区关系示意图，图11(b)为本申请第三实施例提供的网络B的用户终端的第二列表的邻区关系示意图，图 11(c)为本申请第三实施例提供的网络C的用户终端的第二列表的邻区关系示意图，图11(d)为本申请第三实施例提供的网络D的用户终端的第二列表的邻区关系示意图，图11(e)为本申请第三实施例提供的网络E的用户终端的第二列表的邻区关系示意图。
最后，eNode或者gNodeb会将处理后的异频邻区信息中包括的异频频点通过测量控制消息发送给UE，以触发UE进行异频邻区的测量。
在UE将测量结果上报后，eNode或者gNodeb会与配置的邻区进行匹配，匹配成功后执行切换动作。由于本申请中每个PLMN的UE的测量频点已经做了限制和区分，因此，邻区匹配阶段也只会匹配UE的小区级的异频频点列表对应的异频邻区，不会切换到其他频点的邻区。
