Description

邻区切换的调整方法、装置及计算机存储介质 技术领域
本发明涉及通信领域，具体而言，涉及一种邻区切换的调整方法、装置及计算机存储介质。
背景技术
目前，在长期演进(LTE)协议中，自动邻区关系(Automatic Neighbor Relation，简称为ANR)功能已经成为标准的需求内容。自动邻区关系功能可以分为两个阶段：自规划和自优化。
(1)自规划：邻区关系从无到有的过程，即当基站中不存在邻区列表时；
(2)自优化：邻区关系从有到优的过程，即当基站中存在邻区列表时。
在优化邻区关系阶段中，ANR处理邻区关系的添加和删除操作。邻区的自添加操作用以确保邻区关系的完整性，从而提高切换成功率；邻区的自删除操作则用以维护邻区的有效性，合理的优化系统容量，进而从整体达到最小化规划和配置邻区关系。
通过ANR功能可以根据系统内邻区上报次数和切换成功次数等指标为基站添加邻区。如果在将某小区添加为本基站的邻区后，从本基站服务小区向该邻区的切换失败率突然升高，不采取任何措施可能会导致掉话，从而影响用户体验和网络的运行质量；如果将该邻区删除又会造成邻区漏配，而且切换失败率升高的原因有可能是在一个比较短的时间内存在干扰，很快便可恢复。
由此可见，相关技术中缺乏如何提高服务小区下的UE从服务小区切换至相邻小区成功率的解决方案。
发明内容
本发明实施例提供了一种邻区切换的调整方法、装置及计算机存储介质，以至少解决相关技术中缺乏如何提高服务小区下的UE从服务小区切换至相邻小区成功率的解决方案的问题。
根据本发明实施例的一个方面，提供了一种邻区切换的调整方法。
根据本发明实施例的邻区切换的调整方法包括：统计UE从服务小区向邻区切换时对应于各邻区的切换失败率或者切换成功率；确定切换失败率大于第一预设阈值或切换成功率小于第二预设阈值的邻区为待调整邻区；调整待调整邻区的切换权重。
优选地，邻区包括正式邻区和/或临时邻区，临时邻区是服务小区已发现但尚未添加到正式邻区列表的邻区。
优选地，统计UE从服务小区向邻区切换时对应于各邻区的切换失败率或者切换成功率，包括：采集对应于各邻区的切换总次数，以及切换失败次数或切换成功次数；当邻区为正式邻区时，正式邻区列表管理模块确定正式邻区的切换失败率或切换成功率；当邻区为临时邻区时，临时邻区列表管理模块确定正式邻区的切换失败率或切换成功率。
优选地，调整待调整邻区的切换权重包括：降低待调整邻区的切换权重；设定定时器的时长并启动定时器；在定时器超时后，恢复待调整邻区的切换权重。
优选地，定时器的时长为预先设定的值，或者，综合考虑前N次修改切换权重的历史数据进行尝试调整获取到的经验值，其中，N为正整数。
根据本发明实施例的另一方面，提供了一种邻区切换的调整装置。
根据本发明实施例的邻区切换的调整装置包括：统计模块，设置为统计UE从服务小区向邻区切换时对应于各邻区的切换失败率或者切换成功率；确定模块，设置为确定切换失败率大于第一预设阈值或切换成功率小于第二预设阈值的邻区为待调整邻区；调整模块，设置为调整待调整邻区的切换权重。
优选地，邻区包括正式邻区和/或临时邻区，临时邻区是服务小区已发现但尚未添加到正式邻区列表的邻区。
优选地，统计模块包括：采集模块，设置为采集对应于各邻区的切换总次数，以及切换失败次数或切换成功次数；正式邻区列表管理模块，设置为当邻区为正式邻区时，确定正式邻区的切换失败率或切换成功率；临时邻区列表管理模块，设置为当邻区为临时邻区时，确定正式邻区的切换失败率或切换成功率。
优选地，调整模块包括：降低模块，设置为降低待调整邻区的切换权重；设定模块，设置为设定定时器的时长并启动定时器；恢复模块，设置为在定时器超时后，恢复待调整邻区的切换权重。
优选地，定时器的时长为预先设定的值，或者，综合考虑前N次修改切换权重的历史数据进行尝试调整获取到的经验值，其中，N为正整数。
再一方面，本发明实施例还提供一种计算机存储介质，所述计算机存储介质中存储有计算机可执行指令，所述计算机可执行指令用于上述的邻区切换的调整方法。
通过本发明实施例，采用统计UE从服务小区向邻区切换时对应于各邻区的切换失败率或者切换成功率；确定切换失败率大于第一预设阈值或切换成功率小于第二预设阈值的邻区为待调整邻区；调整待调整邻区的切换权重，解决了相关技术中由当前基站的服务小区向邻区切换过程中易造成切换失败率较高影响服务质量的问题，进而改善切换成功率、提高网络运行质量。
附图说明
此处所说明的附图用来提供对本发明的进一步理解，构成本申请的一部分，本发明的示意性实施例及其说明用于解释本发明，并不构成对本发明的不当限定。在附图中：
图1是根据本发明实施例的邻区切换的调整方法的流程图；
图2是根据本发明实施例的邻区切换的调整装置的结构框图；
图3是根据本发明优选实施例的邻区切换的调整装置的结构框图；
图4是根据本发明优选实施例的邻区切换的调整方法的流程图。
具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
图1是根据本发明实施例的邻区切换的调整方法的流程图。如图1所示，该方法可以包括以下处理步骤：
步骤S102：统计UE从服务小区向邻区切换时对应于各邻区的切换失败率或者切换成功率；
步骤S104：确定切换失败率大于第一预设阈值或切换成功率小于第二预设阈值的邻区为待调整邻区；
步骤S106：调整待调整邻区的切换权重。
相关技术中，由当前基站的服务小区向邻区切换过程中易造成切换失败率较高影响服务质量。采用如图1所示的方法，以切换成功率或切换失败率作为判决依据，由服务小区基站统计UE从该服务小区向相邻小区进行切换得到的切换成功率或切换失败率，在确定切换失败率大于第一预设阈值或切换成功率小于第二预设阈值的邻区为待调整邻区的情况下，对待调整邻区的切换权重进行调整。由此解决了相关技术中由当前基站的服务小区向邻区切换过程中易造成切换失败率较高影响服务质量的问题，进而改善切换成功率、提高网络运行质量。
需要说明的是，关于上述切换成功率或切换失败率的统计过程既可以采用按照预设周期的方式进行统计，当然也可以采用特定事件触发的方式进行统计。
在优选实施过程中，上述邻区可以包括正式邻区和/或临时邻区，其中，临时邻区是服务小区已发现但尚未添加到正式邻区列表的邻区。
在优选实施例中，引入了临时邻区的概念，即从ANR功能发现一个未知邻区到将其添加为正式邻区的时间内，将该邻区定义为临时邻区。本基站的某个未知邻区变为临时邻区后，便可以允许本基站向该临时邻区发生切换，这样操作的优势在于：能够在最大程度上满足用户的体验，避免UE因某邻区在从未知邻区变为正式邻区的过程中无法向该邻区发生切换造成掉话，从而提高了系统的可靠性。
优选地，在步骤S102中，统计UE从服务小区向邻区切换时对应于各邻区的切换失败率或者切换成功率可以包括以下步骤：
步骤S1：采集对应于各邻区的切换总次数，以及切换失败次数或切换成功次数；
步骤S2：当邻区为正式邻区时，正式邻区列表管理模块确定正式邻区的切换失败率或切换成功率；
步骤S3：当邻区为临时邻区时，临时邻区列表管理模块确定正式邻区的切换失败率或切换成功率。
在优选实施例中，可以实时采集对应于各邻区的切换总次数，以及切换失败次数或切换成功次数。然后再根据邻区的类型将采集到的数据更新到相应的邻区列表中。即当邻区为正式邻区时，则由正式邻区列表管理模块确定正式邻区的切换失败率或切换成功率；而当邻区为临时邻区时，则由临时邻区列表管理模块确定正式邻区的切换 失败率或切换成功率，进而通过判断切换失败率是否大于第一预设阈值或切换成功率是否小于第二预设阈值来确定待调整邻区，并降低该邻区的切换权重。
优选地，在步骤S106，调整待调整邻区的切换权重可以包括以下操作：
步骤S4：降低待调整邻区的切换权重；
步骤S5：设定定时器的时长并启动定时器；
步骤S6：在定时器超时后，恢复待调整邻区的切换权重。
即计算定时器的时长，并启动该定时器。待定时器超时后，将该邻区的切换权重恢复至初始值。通过使用定时器来执行邻区切换权重的修改与恢复。
在优选实施例中，UE在从服务小区向与该服务小区相邻的小区进行切换的过程中，相邻小区通常会存在与之对应的切换权重，该切换权重用于表征UE从服务小区切换至该相邻小区的切换概率。如果在UE从服务小区切换至特定邻区的切换失败率大于第一预设阈值或切换成功率小于第二预设阈值，则需要降低特定邻区的切换权重，即降低UE从服务小区切换至特定邻区的概率。
在优选实施过程中，上述定时器的时长可以采用以下设定方式之一：
方式一：预先设定的值；此种设定方式较为简单，在每次调整待调整邻区的切换权重后，直接设定一个数值。
方式二：综合考虑前N次修改切换权重的历史数据进行尝试调整获取到的经验值，其中，N为正整数；此种设定方式较为复杂，需要对前N次设定的值进行参考，结合这N次设定的值对待调整邻区的切换权重的调整情况不断对当前取值进行微调，直至获取到较为满意的数值，此为一种经验设定方式。
图2是根据本发明实施例的邻区切换的调整装置的结构框图。如图2所示，该邻区切换的调整装置可以包括：统计模块10，设置为统计UE从服务小区向邻区切换时对应于各邻区的切换失败率或者切换成功率；确定模块20，设置为确定切换失败率大于第一预设阈值或切换成功率小于第二预设阈值的邻区为待调整邻区；调整模块30，设置为调整待调整邻区的切换权重。
采用如图2所示的装置，解决了相关技术中由当前基站的服务小区向邻区切换过程中易造成切换失败率较高影响服务质量的问题，进而改善切换成功率、提高网络运行质量。
优选地，上述邻区可以包括：正式邻区和/或临时邻区，其中，临时邻区是服务小区已发现但尚未添加到正式邻区列表的邻区。
优选地，如图3所示，统计模块10可以包括：采集模块100，设置为采集对应于各邻区的切换总次数，以及切换失败次数或切换成功次数；正式邻区列表管理模块102，设置为当邻区为正式邻区时，确定正式邻区的切换失败率或切换成功率；临时邻区列表管理模块104，设置为当邻区为临时邻区时，确定正式邻区的切换失败率或切换成功率。
优选地，调整模块30可以包括：降低模块300，设置为降低待调整邻区的切换权重；设定模块302，设置为设定定时器的时长并启动定时器；恢复模块304，设置为在定时器超时后，恢复待调整邻区的切换权重。
优选地，上述定时器的时长可以为预先设定的值，或者，综合考虑前N次修改切换权重的历史数据进行尝试调整获取到的经验值，其中，N为正整数。
图4是根据本发明优选实施例的邻区切换的调整方法的流程图。如图4所示，该流程可以包括以下处理步骤：
步骤S402：采集模块实时采集本站所有服务小区到其所有邻区的切换数据，以采集到本站服务小区A到邻区B的切换次数和切换失败次数为例。
步骤S404：采集模块判断邻区B是否为正式邻区，如果是，则继续执行步骤S406，否则，转到步骤S416。
步骤S406：采集模块将采集数据更新至正式邻区列表管理模块。
步骤S408：如果邻区B属于正式邻区，则由正式邻区列表管理模块计算并判断邻区B是否满足切换失败率大于第一预设阈值或切换成功率小于第二预设阈值的条件；如果是，则继续执行步骤S410；如果否，则流程结束。
步骤S410：正式邻区列表管理模块通知降低模块触发降低邻区B的切换权重的操作。
步骤S412：设定模块根据初始设定值或者历史修改邻区切换权重的统计数据计算定时器时长，并启动定时器。
步骤S414：定时器超时，恢复模块恢复邻区B的切换权重，流程结束。
步骤S416：采集模块判断邻区B是否为临时邻区，如果是，则继续执行步骤S418；否则，流程结束。
步骤S418：采集模块将采集数据更新至临时邻区列表管理模块。
步骤S420：如果邻区B属于临时邻区，则由临时邻区列表管理模块计算并判断邻区B是否满足切换失败率大于第一预设阈值或切换成功率小于第二预设阈值的条件；如果是，则继续执行步骤S422；如果否，则流程结束。
步骤S422：临时邻区列表管理模块通知降低模块触发降低邻区B的切换权重的操作。
步骤S424：设定模块根据初始设定值或者历史修改邻区切换权重的统计数据计算定时器时长，并启动定时器。
步骤S426：定时器超时，恢复模块恢复邻区B的切换权重，流程结束。
从以上的描述中，可以看出，上述实施例实现了如下技术效果(需要说明的是这些效果是某些优选实施例可以达到的效果)：采用本发明实施例所提供的技术方案，在ANR功能中引入了修改和恢复邻区的切换权重，使得在通过ANR功能自动添加邻区后可以根据切换总次数和切换失败率等指标控制向该邻区的切换概率；而且定时器时长可以根据历史修改邻区切换权重的统计数据进行自适应调整。这样一方面能够降低切换失败率，确保系统的运行质量，而另一方面又能够实现系统的灵活性。
