Description

一种失步基站确定方法和服务器 技术领域
本申请涉及通信技术领域,尤其涉及一种失步基站确定方法和服务器。
背景技术
基于时分双工(time division duplex,TDD)的通信系统要求具有严格的时钟同步,如果基站之间的时钟较大差异,那么至少存在一个基站的时钟有误,称为基站间的时钟失步。其中,时钟有误的基站称为失步基站,时钟无误的称为同步基站。失步基站的下行可能会干扰到同步基站的上行,同步基站的下行也可能会干扰到失步基站的上行,从而会造成严重的上行同频干扰,导致网络上的终端无法入网,或者业务较差,例如容易引起掉话、切换失败、无法做业务等,从而影响用户体验。
当前,可以通过是否发生时钟参考源丢失,来判断基站是否发生时钟失步。一般的,时钟参考源丢失一段时间后,基站会自动闭塞载扇,防止失步基站对相邻基站造成干扰。但是,时钟参考源丢失未必会引起时钟失步,造成误判。而且,引起时钟失步的原因有很多,除了时钟参考源丢失,还可能有星卡故障、器件软失效、背板传输故障、软件缺陷等。如果仅考虑时钟参考源丢失的情况,其他原因引起的时钟失步会被遗漏。

具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。

本申请实施例的技术方案可以应用于各种数据处理的通信系统,本申请提供的技术方案可适用在各种通信系统中,例如长期演进(long term evolution,LTE)系统、第五代(5th generation,5G)通信系统、以及其它类似的通信系统。此外,所述通信系统还可以适用于面向未来的通信技术,都适用本申请实施例提供的技术方案。本申请实施例描述的系统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。
请参考图1,为本申请所应用的通信系统100,该通信系统100可以包括服务器110和多个基站120。其中,
在一些可行的实现方式中,服务器110可以为一种集中控制判断网元,例如是一个逻辑网元,也可以一个实体网元,此处不做限定。在一些可行的实现方式中,服务器110也可以集成在网管设备或一个基站中,也可以为一个网管设备,此处不做限定。
例如,服务器110为一个网管设备,也可以是多个物理服务器构成的服务器集群或者分布式系统,还可以是提供云服务、云数据库、云计算、云函数、云存储、网络服务、云 通信、中间件服务、域名服务、安全服务、CDN、以及大数据和人工智能平台等基础云计算服务的云服务器,此处不做限定。
本申请实施例中的多个基站120是终端通过无线方式接入到该移动通信系统中的接入设备,例如演进型基站(evolved NodeB,eNB)、发送接收点(transmission reception point,TRP)、5G移动通信系统中的下一代基站(next generation NodeB,gNB)、未来移动通信系统中的基站或WiFi系统中的接入节点等。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。
基于时分双工(time division duplex,TDD)的通信系统要求具有严格的时钟同步,如果基站之间的时钟较大差异,那么至少存在一个基站的时钟有误,称为基站间的时钟失步。其中,时钟有误的基站称为失步基站,时钟无误的称为同步基站。失步基站的下行可能会干扰到同步基站的上行,同步基站的下行也可能会干扰到失步基站的上行,从而会造成严重的上行同频干扰,导致网络上的终端无法入网,或者业务较差,例如容易引起掉话、切换失败、无法做业务等,从而影响用户体验。
当前,可以通过是否发生时钟参考源丢失,来判断基站是否发生时钟失步。一般的,时钟参考源丢失一段时间后,基站会自动闭塞载扇,防止失步基站对相邻基站造成干扰。但是,时钟参考源丢失未必会引起时钟失步,造成误判。而且,引起时钟失步的原因有很多,除了时钟参考源丢失,还可能有星卡故障、器件软失效、背板传输故障、软件缺陷等。如果仅考虑时钟参考源丢失的情况,其他原因引起的时钟失步会被遗漏。另外,当时钟参考源丢失超过一定时限后,基站才会闭塞载扇,造成一定的时延,影响用户体验。
当前,还可以对全网所有基站的各个小区的网络通信质量进行检测,得到网络测量数据,网络测量数据可以包括干扰和噪声(interference and noise,IN)信息或功率信息,对于IN信息或功率信息出现异常的小区作为第一小区,将第一小区按照IN信息或功率信息出现异常的不同类型进行归类,从而确定失步基站。该方法可以及时发现基站失步,以采取措施避免基站失步对网络通信质量造成的影响。但是,网络中的干扰情况较为复杂,除了时钟失步会引起IN信息或功率信息出现异常,大气波导、大话务、伪基站等都可能造成IN信息或功率信息出现异常,仅通过IN信息或功率信息出现异常来判定时钟失步,存在较大误判概率。
当前,基站可以在广播帧中的指定位置广播或接收同步特征序列,能正常接收或发送同步特征序列的基站都被认为同步基站,否则需要进一步通过干扰变化来确定是否失步基站。但是,这无法解决多个基站存在时钟失步的场景。例如,若存在多个基站同时时钟失步,失步基站之间实现了同步,那么失步基站间也可能检出序列,则方案失效。
为此,在本申请中,提出了一种失步基站确定方法,通过确定至少一个同步域,所述同步域中的任意两个相邻的基站为相对时钟同步关系,然后根据所述至少一个同步域确定第一同步域,所述第一同步域中的各个基站均为同步基站,最后确定所述至少一个同步域中与所述第一同步域为相对时钟失步关系的第二同步域,实现了确定所述第二同步域中的各个基站均为失步基站。相比较根据时钟参考源是否丢失来判断失步基站,本申请的失步基站确定方法可以大范围确定失步基站,而且不会造成时延,同时减少了误判和遗漏。
示例性的,请参考图2-1,本申请提出了一种失步基站确定方法的实施例一,包括:
201、第一基站对第一基站的各个小区进行干扰监控,以确定存在时钟失步的干扰特征的小区。
在本申请实施例中,第一基站为通信系统中多个基站中的一个。在本申请实施例中,第一基站可以对第一基站的各个小区进行干扰监控,得到第一基站的各个小区的干扰数据。接着,第一基站根据第一基站的各个小区的干扰数据,判断各个小区是否具有符合时钟失步的干扰特征。在本申请实施例中,当确定第一基站中具有符合时钟失步的干扰特征的干扰异常小区,则触发第一基站执行下述步骤202。需要说明的是,第一基站代指通信系统中的任意基站。
需要说明的是,若第一基站发生时钟失步,则第一基站的最后一个上行子帧的最后若干个符号会受到干扰(可能是来自同步基站的干扰,也可能是来自失步基站的干扰),因此,若第一基站的某个小区的最后一个上行子帧的最后几个符号受到干扰,则可以判断该第一基站可能存在时钟失步。那么,在一些可行的实现方式中,小区的干扰数据为该小区的最后一个上行子帧的最后若干个符号的平均干扰功率。在一些可能的实现方式中,若该干扰异常小区的上行子帧的最后若干个符号的平均干扰功率高于阈值,则可以认为该干扰异常小区具有时钟失步的干扰特征,即该干扰异常小区为存在时钟失步的干扰特征的小区。
示例性的,若第一基站的干扰异常小区的最后一个上行子帧的最后4个符号上的平均干扰功率大于阈值,则确定该干扰异常小区为具有时钟失步的干扰特征。在一些可行的实现方式中,第一基站可以周期性对第一基站的各个小区进行干扰监控,例如一个周期为1秒钟,或者10秒钟,此处不做限定。
举例说明,第一基站可以在每个周期计算各个小区的最后一个上行子帧的最后4个符号上的平均干扰功率,若该平均干扰功率大于等于阈值,排除大话务的因素,那么第一基站可以确定该小区为具有时钟失步的干扰特征。例如,第一基站具有3个小区,分别为小区1、小区2和小区3,小区1、小区2和小区3的最后的一个上行子帧的最后若干个符号的平均干扰功率分别等于6、8、10。假设阈值为8,由于6≤8,8=8,10>8,排除大话务的因素,那么第一基站确定平均功率等于8、10对应的小区2和小区3具有时钟失步的干扰特征。
在本申请实施例中,第一基站通过上述方式对于第一基站的所有小区的干扰监控,可即时发现时钟失步造成的干扰,同时又避免了其它原因造成的干扰造成的时钟失步检测流程,以免造成误判。
202、多个基站向服务器上报干扰事件,得到干扰事件集合。
在本申请实施例中,当第一基站对第一基站的各个小区进行干扰监控,确定了干扰异常小区后,第一基站可以将干扰异常小区及其干扰数据汇总成第一基站的干扰数据,并向服务器上报干扰事件,该干扰事件指示第一基站中存在干扰异常小区及其干扰数据。在一些可行的实现方式中,第一基站还可以获得大气波导和业务高负载等产生的干扰数据,当第一基站向服务器发送第一基站的干扰数据时,可以过滤掉大气波导和业务高负载产生的干扰,此处不做限定。
203、服务器根据干扰事件集合从多个邻站连通域中确定多个待检基站及其相邻基站,其中,邻站连通域包括上报干扰事件的基站及其相邻基站。
需要说明的是,若第一基站以其相邻基站发生相对时钟失步,会对第一基站及其相邻基站的小区产生干扰。因此,在本申请实施例中,当服务器接收到多个基站上报的干扰事件后,汇聚成干扰事件集合,以上报干扰事件的第一基站及其相邻基站作为一个邻站连通域,得到多个邻站连通域,从多个邻站连通域中确定多个待检基站及其相邻基站。在本申请实施例中,以第二基站为多个待检基站中的一个基站,第三基站为第二基站的相邻基站。
在一些可行的实现方式中,服务器可以在干扰事件集合所指示的多个收到干扰小区中,按照上报的平均干扰功率从大到小排序,取最大的前几个平均干扰功率的小区,其对应的基站作为多个待检基站。例如,基站1、基站2、基站3和基站4都上报了其某个小区的平均干扰功率,分别等于6、7、8、9,则服务器可以确定平均干扰功率为8的小区和平均干扰功率为9的小区4,其对应的基站作为多个待检基站。
在本申请实施例中,称两个基站互为相邻基站,即这其中一个基站中的某个小区为另一个基站的某个小区的相邻小区。需要说明的是,若终端设备可以从一个小区切换到另一个小区,那么这两个小区互为相邻小区。在一些可行的实现方式,第二基站的相邻基站可以有一个或多个,此处不做限定。在本申请实施例中,以第三基站代指所述第二基站的其中一个相邻基站。需要说明的是,第二基站可以同时是待检基站,以及其他的待检基站的相邻基站。例如,基站3和基站4互为相邻基站,基站3和基站4都是待检基站。
204、服务器对多个待检基站及其相邻基站进行关于同步/失步检测的配置。
在本申请实施例中,以第二基站为待检基站,以第三基站为第二基站的相邻基站为例进行说明。示例性的,服务器对第二基站和第三基站进行关于同步/失步检测的配置,包括服务器对第二基站和第三基站进行关于同步检测的配置,和/或,服务器对第二基站和第三基站进行关于失步检测的配置。其中,服务器对第二基站和第三基站进行关于同步检测的配置,和,服务器对第二基站和第三基站进行关于失步检测的配置,二者可以是两个单独的流程,二者也可以同时进行,此处不做限定。
在一些可行的实现方式中,服务器对第二基站进行关于同步/失步检测的配置,可以为服务器向第二基站指示在约定的时间段广播携带同步/失步特征序列的消息,同时向第三基站指示在该约定的时间段内接收携带同步/失步特征序列的消息。其中,服务器向第二基站指示在约定的第一时间段广播携带同步特征序列的消息,同时向第三基站指示在该约定的第一时间段内接收携带同步特征序列的消息。服务器向第二基站指示在约定的第二时间段广播携带同步特征序列的消息,同时向第三基站指示在该约定的第二时间段内接收携带同步特征序列的消息。
需要说明的是,基于TDD的通信系统对时钟严格同步的要求,服务器指示的第一时间段可以为第二基站的一个子帧的下行和上行之间的保护周期(guard period,GP)时间段。若第三基站和第二基站是相对时钟同步关系,且没有无线基站隔离,则第三基站可以正常接收到该携带同步特征序列的消息。由此可知,在第一时间段广播的携带同步特征序列的 消息只能用于测量第二基站和第三基站之间是否相对时钟同步关系,无法测量第二基站和第三基站之间是否时钟失步。例如,第三基站和第二基站是相对时钟同步关系,但是由于无线基站隔离,导致第三基站无法接收到第二基站发送的同步特征序列,无法因此认为第三基站和第二基站是相对时钟失步关系。
需要说明的是,基于TDD的通信系统对时钟严格同步的要求,服务器指示的第二时间段可以为第二基站的一个子帧的下行时间段。若第三基站和第二基站是相对时钟同步关系,则第三基站无法正常接收到该携带同步特征序列的消息。若第三基站正常接收到该携带该同步特征序列的消息,说明第三基站此时在上行时间段,即第三基站和第二基站是相对时钟失步关系。由此可知,在第二时间段广播的携带失步特征序列的消息用于测量第二基站和第三基站之间是否相对时钟失步关系,无法测量第二基站和第三基站之间是否相对时钟同步关系。例如,第三基站和第二基站是相对时钟失步关系的,但是由于无线基站隔离,导致第三基站无法接收到第二基站发送的失步特征序列,无法因此认为第三基站和第二基站是相对时钟同步关系。
在一些可行的实现方式中,若第二基站和第三基站均为内置有同步/失步特征序列,服务器可以在对第二基站和第三基站进行关于同步/失步检测的配置时,向第二基站和第三基站发送所使用的同步/失步特征序列。
在一些可行的实现方式中,第二基站也可以预先内置有1个同步特征序列和1个失步特征序列。那么,服务器可以在对第二基站和第三基站进行关于同步/失步检测的配置时,无需向第二基站和第三基站指示使用的同步/失步特征序列。
在一些可行的实现方式中,第二基站也可以预先内置有多个同步特征序列和多个失步特征序列。那么,服务器可以在对第二基站和第三基站进行关于同步/失步检测的配置时,需向第二基站和第三基站指示使用的同步/失步特征序列。
在一些可行的实现方式中,第二基站也可以预先内置有1个同步特征序列和8个失步特征序列。那么,服务器可以在对第二基站和第三基站进行关于同步检测的配置时,无需向第二基站和第三基站指示使用的同步特征序列;服务器可以在对第二基站和第三基站进行关于同步检测的配置时,需要指示使用的失步特征序列。
在本申请实施例中,服务器对第二基站进行关于同步/失步检测的配置还包括,使第二基站在目标时间段广播携带同步/失步特征序列的消息之后,向服务器反馈广播成功响应;且,使第二基站在未能在目标时间段成功广播携带同步/失步特征序列的消息,向服务器反馈广播失败响应。
在本申请实施例中,服务器对第三基站进行关于同步/失步检测的配置还包括,使第三基站在目标时间段接收到携带同步/失步特征序列的消息之后,向服务器反馈接收成功响应;且,使第三基站在未能在目标时间段成功接收到携带同步/失步特征序列的消息,向服务器反馈接收失败响应。
205、第二基站广播携带同步/失步特征序列的消息。
在本申请实施例中,第二基站可以在第一时间段广播携带同步特征序列的消息,和/或,第二基站可以在第二时间段广播携带失步特征序列的消息。需要说明的是,第一时间 段可以为第二基站的一个子帧的上行时间段和下行时间段之间的GP时间段,第二时间段可以为第二基站的下行时间段。
206、第二基站向服务器发送响应消息。
在一些可行的实现方式中,当第二基站成功广播携带同步/失步特征序列的消息后,可以向服务器发送广播成功响应消息。在一些可行的实现方式中,若由于小区未开,或者当第二基站错过了广播携带同步/失步特征序列的消息的约定的时间段,导致第二基站未能成功在约定的时间段广播携带同步/失步特征序列的消息,那么第二基站向服务器发送广播失败响应消息。
207、第三基站向服务器发送同步检测响应消息。
在一些可行的实现方式中,当第三基站成功接收到携带同步/失步特征序列的消息后,可以向服务器发送接收成功响应消息。在一些可行的实现方式中,若第三基站未能成功在约定的时间段接收到携带同步/失步特征序列的消息,那么第三基站向服务器发送接收失败响应消息。
需要说明的是,第三基站为第二基站的相邻基站,第二基站可以有多个相邻基站,那么服务器可以接收到第二基站的各个相邻基站反馈的接收失败响应消息或接收成功响应消息,从而确定第二基站和其相邻基站之间的相对时钟同步/失步关系。
208、服务器检测所述多个待检基站的各个基站与其相邻基站的相对时钟同步关系和/或相对时钟失步关系,得到多个基站之间的相对时钟同步/失步关系集合。
在一些可行的实现方式中,若服务器接收到第三基站发送的对同步特征序列的消息的接收成功响应消息,则可以判断第三基站和第二基站是相对时钟同步关系,那么第三基站和第二基站属于相同的同步域。
在一些可行的实现方式中,若服务器接收到第三基站发送的对同步特征序列的消息的接收失败响应消息,则不可判断第三基站和第二基站是相对时钟同步关系,也不能判断第三基站和第二基站是相对时钟失步关系。
在一些可行的实现方式中,若服务器接收到第三基站发送的对失步特征序列的消息的接收成功响应消息,则可以判断第三基站和第二基站是相对时钟失步关系,那么第三基站和第二基站不属于相同的同步域。
在一些可行的实现方式中,若服务器接收到第三基站发送的对失步特征序列的消息的接收失败响应消息,则不可判断第三基站和第二基站是相对时钟失步关系,也不能判断第三基站和第二基站是相对时钟失步关系。
在一些可行的实现方式中,若服务器同时接收到第三基站发送的对失步特征序列的消息的接收失败响应消息,以及第三基站发送的对同步特征序列的消息的接收失败响应消息,则判断第三基站和第二基站是无线基站隔离,二者之间无法通信。
在一些可行的实现方式中,若服务器同时接收到第三基站发送的对失步特征序列的消息的接收成功响应消息,以及第三基站发送的对同步特征序列的消息的接收成功响应消息, 则判断第三基站和第二基站存在例如部分RRU失步,或者基站之间的时差处于某个临界区间,则后续需要进行分裂,此处不做赘述。
209、服务器根据相对时钟同步/失步关系集合确定至少一个同步域。
需要说明的是,同步域内的互为相邻基站的任意两个基站之间是相对时钟同步关系。在一些可行的实现方式中,根据相对时钟同步/失步关系集合确定具有相对时钟同步关系的两个基站属于相同的同步域;根据相对时钟同步/失步关系集合确定具有相对时钟失步关系的两个基站属于不同的同步域。
例如,存在5个基站,分别为基站1、基站2、基站3、基站4和基站5。其中,基站1和基站2是时钟同步关系,属于同步域1;基站3、基站4和基站5是时钟同步关系,属于同步域2。
需要说明的是,相对时钟同步关系具有传递性。例如,在未检测基站3和基站5之间的时钟同步关系的情况下,由于基站3和基站4是相对时钟同步关系,基站4和基站5是相对时钟同步关系,可以认为基站3和基站5是相对时钟同步关系。
示例性的,若同步域1中的任意一个基站和同步域2中的任意一个基站是相对时钟同步关系,那么同步域1中任何基站和同步域2中的任何基站都是相对时钟同步关系,那么同步域1和同步域2可以合并为一个同步域。例如,同步域1包括基站1和基站2,同步域2包括基站3、基站4、基站5,若基站1和基站3是相对时钟同步关系,那么同步域1和同步域2可以合并为一个同步域。
在本申请实施例中,服务器确定各个待检基站及其相邻基站之间的相对时钟同步/失步关系之后,可以根据基站之间的相对时钟同步/失步关系确定至少一个空口连通域。需要说明的是,空口连通域内的两个基站可以直接或间接通信。例如,第二基站和第三基站之间,若第三基站可以接收到第二基站发送的携带同步/失步特征序列的消息,那么,第二基站和第三基站属于同一个空口连通域。需要说明的是,确定同一个空口连通域具有传递性。例如,在未检测基站3和基站5之间的时钟同步/失步关系的情况下,或者基站3和基站5之间无法直接通信的情况下(即第三基站无法接收到第二基站发送的携带同步/失步特征序列的消息,或第二基站无法接收到第三基站发送的携带同步/失步特征序列的消息),由于基站3和基站4属于同一个空口连通域,基站4和基站5属于同一个空口连通域,可以认为基站3和基站5属于同一个空口连通域。进一步的,若空口连通域1中的任意一个基站可以和空口连通域2中的任意一个基站之间实现直接或间接通信,那么可以合并空口连通域1和空口连通域2为一个空口连通域。
在本申请实施例中,基站控制判断网元可以将具有相对时钟同步关系的多个基站看做一个同步域。例如,基站1、基站2、基站3、基站4、基站5,其中,基站1和基站2是相对时钟同步关系,基站3、基站4、基站5是相对时钟同步关系,那么,基站1和基站2属于相同的同步域(设为同步域1),基站3、基站4、基站5属于相同的同步域(设为同步域2)。其中,若基站1和基站3是相对时钟失步关系,那么,同步域1中的任意基站和同步域2中的任意基站是相对时钟失步关系。
在一些可行的实现方式中,若同步域1的任一基站和同步域2的任一基站是相对时钟 同步关系,那么同步域1和同步域2可以合并为同一个同步域。在一些可行的实现方式,若基站1属于同步域1,基站3属于同步域2,若基站1是基站3的相邻基站,若基站1和基站3的相对时钟同步关系,则可以合并同步域1和同步域2。若基站1不是基站3的相邻基站,若存在基站6是基站1的相邻基站,同时是基站3的相邻基站,若基站6与基站1是相对时钟同步关系,基站6与基站3也是相对时钟同步关系,那么也可以确定基站1和基站3也是相对时钟同步关系,那么也可以合并同步域1和同步域2,同时基站6属于同步域1也属于同步域2,也属于合并后的同步域。
在本申请实施例中,当服务器确定了至少一个同步域后,若同步域的数量为1,则确定该同步域的所有基站均为同步基站,不存在失步基站。若同步域的数量大于1,那么,服务器可以根据基站之间的相对时钟失步关系确定同步域之间的相对时钟失步关系,使得相邻的两个同步域之间确定相对时钟失步关系。
示例性的,若同步域1中的任意一个基站和同步域2中的任意一个基站是相对时钟失步关系,那么同步域1中任何基站和同步域2中的任何基站都是相对时钟失步关系,那么同步域1和同步域2是相对时钟失步关系。例如,同步域1包括基站1和基站2,同步域2包括基站3、基站4、基站5,若基站1和基站3是相对时钟失步关系,那么同步域1和同步域2是相对时钟失步关系。
需要说明的是,当两个同步域属于同一个空口连通域,才能确定这两个同步域是否相对时钟失步关系。若两个同步域不属于一个空口连通域,那么其中一个同步域中的基站和另一个同步域中的基站无法测量是否相对时钟失步关系,即无法检测两个同步域是否相对时钟失步关系。因此,可能存在无法测量两个同步域之间是否为相对时钟失步关系的情况。若两个同步域不是相对时钟同步关系,也不是相对时钟失步关系,那么这两个同步域属于未检测相对时钟同步/失步关系的情况。需要说明的是,空口连通域包括一个或多个基站,若空口连通域包括2个或以上的基站,属于同一个空口连通域的两个基站可以直接或间接通信。例如,基站1和基站2可以直接通信,基站2和基站3可以直接通信,即基站1和基站3可以间接通信,基站1和基站3属于同一个空口连通域。
210、若根据所述至少一个同步域中没有基站权重之和占比高于预设比例的同步域,则服务器确定补检基站及其相邻基站。
在本申请实施例中,补检包括同步序列补检和失步序列补检,下面分别进行描述。
一、同步序列补检。
需要说明的是,进行同步序列补检的目的是用于扩展一个或多个同步域,直到有一个同步域满足预设比例的要求为止。
在本申请实施例中,扩展同步域有两种场景:1、相邻的同步域间已经明确是相对时钟失步关系,则需要向外扩展;2、相邻的同步域之间未明确是相对时钟失步关系,则需要尝试能否合并。在本申请实施例中,当确定了空口连通域和扩展连通域后,依次处理每个扩展连通域。在一些可行的实现方式中,可以从基站的数量最多的扩展连通域开始处理。
举例说明,假设扩展连通域中存在4个同步域,分别为:A、B、C、D。服务器对这4 个同步域执行下述步骤:
1、进行同步域的合并而选择的补检的第四基站。
遍历A、B、C、D中任意两个同步域(同步域1和同步域2),遍历同步域1中基站,选择一个和同步域2有最多相邻基站的基站作为补检的第四基站。需要说明的是,如果同步域1和同步域2已经明确相对时钟失步关系,或者同步域1中任一基站与同步域2中任一基站互为相邻基站,则跳过同步域1和同步域2,重新选择两个同步域。
2、进行同步域的扩展而选择的补检的第四基站。
遍历A、B、C、D中任意一个同步域(同步域1),遍历同步域1的域外邻站(即为同步域1中一个基站的相邻基站,但不是同步域1中基站),选择其中一个具有在同步域1中互为相邻基站的基站,作为补检的第四基站。
二、失步序列补检。
需要说明的是,进行失步序列补检的目的是用于确定同步域之间的失步关系。若所有相邻的同步域之间都已经确定为相对时钟失步关系,则不需要进行失步序列补检。
在本申请实施例中,当确定了空口连通域和扩展连通域后,依次处理每个扩展连通域。在一些可行的实现方式中,可以从基站的数量最多的扩展连通域开始处理。举例说明,假设扩展连通域中存在4个同步域,分别为:A、B、C、D。服务器对这4个同步域执行下述步骤:
1、进行同步域的合并而选择补检的第四基站。
在一些可行的实现方式中,所述补检基站为第一同步域中的基站,所述补检基站的至少一个相邻基站为第二同步域中,所述至少一个同步域包括所述第一同步域和所述第二同步域。
示例性的,遍历A、B、C、D中任意两个同步域(同步域1和同步域2),若同步域1和同步域2未确定相对时钟失步关系,则遍历同步域1中基站,选择一个和同步域2有最多相邻基站的基站作为补检的第四基站,若相邻基站的数量相等,则进一步选择干扰最强的基站。需要说明的是,如果同步域1和同步域2已经明确相对时钟失步关系,或者同步域1中任一基站与同步域2中任一基站互为相邻基站,则跳过同步域1和同步域2,重新选择两个同步域。
2、进行同步域的扩展而选择补检的第四基站。
在一些可行的实现方式中,所述补检基站为所述第一同步域中至少一个基站的相邻基站,所述至少一个同步域包括所述第一同步域,且所述补检基站不属于所述至少一个同步域中的任何一个同步域。
示例性的,遍历A、B、C、D中任意一个同步域(同步域1),遍历同步域1的域外邻站(即为同步域1中一个基站的相邻基站,但不是同步域1中基站),选择其中一个具有在同步域1中的相邻基站的基站,作为补检的第四基站。
在本申请实施例中,依次处理所有扩展连通域,直到已选基站的数量大于或等于预设值(例如180)已经没有基站可以被选出。
例如,当确定了补检的第四基站后,可以根据第四基站的相邻基站。需要说明的是,第四基站可以具有多个相邻基站,在此以第五基站代指。然后,服务器对第四基站和第五基站进行关于同步/失步检测的配置;(具体的,请参考步骤204,此处不做赘述)第四基站广播携带同步/失步特征序列的消息;(具体的,请参考步骤205,此处不做赘述);第四基站向服务器发送响应消息;(具体的,请参考步骤206,此处不做赘述)第五基站向服务器发送同步检测响应信息;(具体的,请参考步骤207,此处不做赘述)服务器确定第四基站和第五基站的相对时钟同步/失步关系;(具体的,请参考步骤208,此处不做赘述)服务器根据基站之间的时钟同步/失步关系确定至少一个同步域。(具体的,请参考步骤209,此处不做赘述)
211、服务器根据至少一个同步域确定第一同步域,第一同步域中的各个基站均为同步基站。
在本申请实施例,服务器可以根据所述相对时钟同步/失步关系集合确定具有相对时钟同步关系的两个基站属于相同的同步域,并根据所述相对时钟同步/失步关系集合确定具有相对时钟失步关系的两个基站属于不同的同步域。
示例性的,根据所述至少一个同步域中确定基站权重之和在所在的扩展连通域中占比高于预设比例的所述第一同步域,所述基站权重之和为同步域中各个基站的权重之和,所述扩展连通域包括空口连通域和所述多个邻站连通域,所述空口连通域包括至少一个基站,所述空口连通域中的任意2个基站可以直接或间接通信。
在一些可行的实现方式中,若根据所述至少一个同步域中没有基站权重之和占比高于预设比例的同步域,则服务器确定补检基站及其相邻基站,根据所述补检基站及其相邻基站合并和/或扩展所述至少一个同步域。
212、服务器确定至少一个同步域中与第一同步域为相对时钟失步关系的第二同步域,以第二同步域中的各个基站均为失步基站。
在本申请实施例中,当服务器确定了至少一个同步域后,若同步域的数量为1,则确定该同步域的所有基站均为同步基站,不存在失步基站。若同步域的数量多于1,且存在一个同步域的权重和大于预设比例,则确定该同步域内的所有基站都是同步基站,而与同步域是时钟失步关系的其他同步域内的所有基站都是失步基站。
示例性的,若有2个同步域,分别为同步域1、同步域2,且同步域1和同步域2是时钟失步关系。若预设比例为60%,若同步域1的权重大于60%,那么同步域1中的所有基站均为同步基站,同步域2中的基站均为失步关系。若同步域1和同步域2之间存在无线基站隔离,那么则确定同步域1中的所有基站,以及同步域2中的所有基站,均为同步基站。需要说明的是,无线基站隔离即同步域1中的任意基站和同步域2中的任意基站都不在同一个空口连通域中,即同步域1和同步域2不属于同一个空口连通域。
需要说明的是,在一个网络中,不同的基站可能属于不同的扩展连通域,在一些可行的实现方式中,以扩展连通域为单位,分别确定其中的失步基站。需要说明的是,扩展连通域包括空口连通域和多个邻站连通域,其中,邻站连通域包括上报干扰事件的基站及其 相邻基站。例如,第一基站及其所有相邻基站构成一个邻站连通域。在一些可行的实现方式中,可以通过以下判定算法来确定失步基站:
步骤1、若扩展连通域中的同步域1的基站数量占比达到预设比例(例如60%,预设比例可配置),则该同步域1内所有基站均被判定为同步基站。
步骤2、与同步基站具有失步关系的所有基站均被判定为失步基站。
步骤3、若扩展连通域中的同步域2包括失步基站,则该同步域2内的所有基站均为失步基站。
需要说明的是,在现网中,两个基站可能既检测出相对时钟同步关系,也检测出相对时钟失步关系。例如,一个基站内的部分射频拉远单元(remote radio unit,RRU)发生时钟失步,或者该基站的时差处于某个临界区间,都会导致两个基站既检测出相对时钟同步关系,也检测出相对时钟失步关系的情况。
示例性的,若同步域1中的基站数量占比达到预设比例,即判定该同步域1中的所有基站均为同步基站。假设同步域1包括10个基站,分别是a,b,c,d,e,f,g,h,i,j,均为同步基站,但是a-b,a-c,a-d是时钟失步关系。按照步骤2,a,b,c,d都应该被判定为失步基站,或同步域1内的所有基站都是失步基站,从而产生矛盾。
在一些可行的实现方式中,若存在上述矛盾,即发现同步域内存在时钟失步关系的两个基站,则先做基站的站点分裂。下面对站点分裂进行详细描述。
示例性的,若在一个同步域中存在相对时钟失步关系的基站a和基站b,基站a和基站b互为相邻基站,则对基站a进行站点分裂,得到实体基站a和虚拟基站a。使虚拟基站a作为实体基站a的相邻基站,以及基站b的相邻基站。使基站a和基站b解除互为相邻基站的关系。举例说明,如图2-2所示,在同步域A中,a-b,a-c,a-d是相对时钟失步关系。那么可以从a,b,c,d,e中选择进行站点分裂的基站。其中,a的失步连线有2个,d的失步连线有2个,b,c,e的失步连线均有1个,那么可以确定a和d为进行站点分裂的基站。
如图2-3所示,对a和d进行站点分裂后,a变成两个基站:实体基站a,虚拟基站a;d变成两个基站:实体基站d,虚拟基站d。其中,实体基站a,虚拟基站a是时钟失步关系,实体基站d,虚拟基站d是时钟失步关系。接着,使虚拟基站a和实体基站a,b,c有失步连线,使虚拟基站d和a,d,e有失步连线,那么虚拟基站a和虚拟基站d排除在该同步域A之外,使a和c无直接通信,d和e无直接通信。
通过上述对a和d的站点分裂,同步域A内不存在时钟失步关系。需要说明的是,虚拟基站a是算法需要而增加的虚拟基站,在一些可行的实现方式中,若虚拟基站a被判定为失步基站,在客户面显示为a是失步基站。
在一些可行的实现方式中,服务器可以确定所述至少一个同步域之间的失步连线,通过失步连线连接的两个同步域为相对时钟失步关系,确定所述至少一个同步域中具有最多失步连线的第三同步域,并使所述第二同步域中的基站退出服务。
示例性的,经过上述站点分裂后,可以将一个同步域看成一个节点,每个节点具有一个权重,为该同步域中所有基站的权值之和,同步域之间可以存在失步连线。需要说明的 是,基站的权重可以由服务器确定,也可以由基站上报给服务器,此处不做限定。例如,基站内存在两个时钟源,若两个时钟源一致,那么该基站的权重较高;若两个时钟源不一致,那么该基站的权重较低。
在本申请实施例中,可以找到消除同步域之间的失步连线需要删除的最小节点集合,如果最小节点集合内基站数量小于等于预设数量(例如100),且最小节点集合的权值之和在该扩展连通域内所有基站的权值和的占比小于预设比例(例如34%),那么判定该最小节点集合内的所有同步域的所有站点均为失步基站。如果不满足上述条件,那么判定最小节点集合内所有同步域的所有基站为失嫌站点,交由人工处理。
需要说明的是,对于确定要进行站点分裂的基站,可以遵循最少站点损失原则,即要消除所有失步关系的连线,所要删除的基站最少。需要说明的是,删除基站相当于基站退服,可以把该基站相连的失步连线全部消除,这就转化为一个数学问题,如何删除最少的基站,使得失步连线全部消除。
需要说明的是,对于存在失步关系的两个基站,意味着两个基站之间存在干扰,若能够消除失步关系,则消除这种干扰。在一些可行的实现方式中,可以确定同步域内的各个基站之间的失步连线的数量,然后按照数量进行从大到小排序,然后对存在最多失步连线的若干个基站进行删除。例如,如图2-4所示,基站3,5,6,7分别具有4个、5个、3个、3个失步连线,其中,删除基站3,5,6后,即可消除所有失步连线。在一些可行的实现方式中,上述的一个基站也可以替换为一个同步域,此处不做限定。
需要说明的是,对于前述的各方法实施例,为了简单描述,故将其都表述为一系列的动作组合,但是本领域技术人员应该知悉,本申请并不受所描述的动作顺序的限制,因为依据本申请,某些步骤可以采用其他顺序或者同时进行。其次,本领域技术人员也应该知悉,说明书中所描述的实施例均属于优选实施例,所涉及的动作和模块并不一定是本申请所必须的。
