Description

小区搜索的方法及装置
本申请要求于2021年02月01日提交中国专利局、申请号为202110139492.2、申请名称为“小区搜索的方法及装置”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,尤其涉及一种小区搜索的方法及装置。
背景技术
运营商对第五代通信技术(the 5 Generation Mobile Communication Technology,5G)网络的部署是逐步推进的,5G独立组网(StandAlone,SA)的大范围部署需要较长的时间。
在5G网络部署的初期,将会优先采用非独立组网(Non-StandAlone,NSA)布局。目前,NSA网络尚未覆盖全部的第四代通信技术(the 4 Generation Mobile Communication Technology,4G)网络。部分4G小区可以配置长期演进(Long Term Evolution,LTE)和新空口(New Radion,NR)的双连接(Dual Connectivity,DC),使终端设备驻留在这些4G小区时,可以使用5G网络,进而享受5G的高速率,提升了用户体验。部分4G小区暂时无法配置LTE和NR的双连接,使终端设备驻留在这些4G小区时,只能使用4G网络,降低了用户体验。也就是说,4G小区的选择直接决定了终端设备是否可以使用5G网络,从而影响用户体验。
在5G网络部署的初期,大部分运营商使用ENDC(E-UTRA NR DC)架构实现LTE和NR的双连接。在ENDC架构中,不需要新增5G核心网,新增的NR基站(即5G基站gNB)可以通过LTE基站(即4G基站eNB)接入4G核心网,由LTE基站和NR基站协同为终端设备提供4G+5G的服务。
终端设备支持的双连接频点组合,与网络侧支持的双连接频点组合,可能存在不匹配的问题,从而导致终端设备在驻留在某些4G小区时,网络侧无法为终端设备添加辅节点小区组(Secondary Cell Group,SCG),从而无法实现终端设备的双连接,使得终端设备不能享受5G高速率,用户体验差。
发明内容
有鉴于此,提出了一种小区搜索的方法及装置,能够使终端设备优先驻留到能够实现长期演进LTE和新空口NR双连接的小区,从而提升用户体验。
第一方面,本申请的实施例提供了一种小区搜索的方法,所述方法包括:
第一终端设备获取目标频点,所述目标频点为成功添加辅小区组SCG的频点,第一终端设备针对所述目标频点进行小区搜索,并驻留在搜索到的小区中。
在本申请实施例中,在存在目标频点的情况下,针对目标频点进行小区搜索,从而使终端设备优先针对曾成功添加SCG的频点发起小区搜索,提高终端设备优先驻留到能够添加SCG的小区的几率,从而使终端设备能够使用LTE和NR双连接来获取高速的数据服务,提升用户体验。
根据第一方面,在所述小区搜索的方法的第一种可能的实现方式中,在获取目标频点之前,所述方法还包括:获取待搜索频点;所述获取目标频点,包括:从所述待搜索频点中,获取所述目标频点;其中,待搜索频点通过如下方式获得:将历史驻留过的频点,确定为所述待搜索频点,和/或,将所述第一终端设备中预设的频点,确定为所述待搜索频点,和/或,将扫频结果中的频点,确定为所述待搜索频点。

具体实施方式
以下将参考附图详细说明本申请的各种示例性实施例、特征和方面。附图中相同的附图标记表示功能相同或相似的元件。尽管在附图中示出了实施例的各种方面,但是除非特别指出,不必按比例绘制附图。
在这里专用的词“示例性”意为“用作例子、实施例或说明性”。这里作为“示例性”所说明的任何实施例不必解释为优于或好于其它实施例。
另外,为了更好的说明本申请,在下文的具体实施方式中给出了众多的具体细节。本领域技术人员应当理解,没有某些具体细节,本申请同样可以实施。在一些实例中,对于本领域技术人员熟知的方法、手段、元件和电路未作详细描述,以便于凸显本申请的主旨。
图1示出ENDC组网的架构示意图。图1中采用虚线表示控制面的连接,采用实线表示用户面的连接。如图1所示,在ENDC组网中,控制面上以LTE基站为主节点(Master Node,MN),NR基站为辅节点(Secondary Node,SN),主节点与分组核心演进(Evolved Packet Core,EPC,即4G核心网)连接,主节点与辅节点为终端设备与EPC之间的数据提供空口传输资源。当终端设备驻留到LTE小区并进入连接状态之后,控制面上作为主节点的LTE基站会决定是否添加作为辅节点的NR基站,即是否为终端设备添加辅节点小区组(Secondary Cell Group,SCG)。在为终端设备添加了SCG的情况下,可以使终端设备能够实现LTE和NR双连接,从而提高传输速率,提升用户体验。
考虑到,NSA中大量并存支持ENDC的小区和不支持ENDC的小区,终端设备优先驻留到支持ENDC的小区来获取数据服务,可以提升用户体验。相关技术中,终端设备驻留在一个小区之后,若该4G小区添加了SCG,或者该4G小区虽然没有添加SCG但该小区的消息中配置了上层指示(Upper Layer Indication,ULR),则终端设备认为该小区支持ENDC,从而将该小区的频点确定为支持ENDC的频点。终端设备再次搜网时,可以优先针对支持ENDC的频点发起小区搜素,从而使终端设备优先驻留到支持ENDC的小区来获取数据服务。
在ENDC组网中,终端设备驻留的小区为4G小区,为该4G小区添加的SCG中的小区为5G小区。也就是说,在ENDC组网中,4G小区作为终端设备的主小区,5G小区作为终端设备的辅小区。在实际应用中,运营商还可以使用NEDC(NR E-UTRA DC)架构实现LTE和NR的双连接。在NEDC组网(未示出)中,控制面上以NR基站为主节点,以LTE基站为辅节点。终端设备驻留的小区为5G小区之后,为该5G小区添加的SCG中的小区为4G小区。也就是说,在NEDC组网中,5G小区作为终端设备的主小区,4G小区作为终端设备的辅小区。本申请实施例提供的小区搜索的方法既可以应用于ENDC组网又可以适用于NEDC组网,本申请实施例中,以ENDC组网为示例进行说明。
图2示出相关技术中网络侧添加SCG的过程示意图。如图2所示,假设终端设备1将B1确定为支持ENDC的频点,且终端设备1支持的双连接频点组合为:B1+N78(即终端设备1驻留在B1小区时,终端设备支持为B1小区添加频点为N78的SCG);网络侧支持的双连接频点组合为B1+N1(即终端设备1驻留在B1小区时,网络侧支持为B1小区添加频点为N1的SCG)。在终端设备1驻留B1小区(即频点为B1的小区)后,终端设备1向网络侧(如图2所示的LTE基站)上报其支持的双连接频点组合B1+N78。网络侧发现自身支持的双连接频点组合B1+N1与终端设备1上报的双连接频点组合B1+N78不匹配。此时,网络侧不会为B1小区添 加SCG,终端设备1无法实现LTE和NR的双连接,终端设备1无法享受到5G高速率,导致用户体验较差。
为了解决上述问题,本申请实施例提供了一种小区搜索的方法,能够使终端设备优先针对曾成功添加SCG的频点发起小区搜索,提高终端设备优先驻留到能够添加SCG的小区的几率,从而使终端设备能够使用LTE和NR双连接来获取高速的数据服务,提升用户体验。
本申请实施例提供的小区搜索的方法可以应用于终端设备开机搜索阶段,也可以应用于终端设备切换小区阶段,当然还可以应用于其他需要进行小区选择的情况,对此本申请不做限制。
在本申请实施例中,终端设备需要首先获取成功添加SCG的目标频点,以优先对目标频点进行搜索。
在实施例中,终端设备中可以存储至少一个频点列表,该频点列表用于指示曾成功添加SCG的小区的频点,以及该小区添加的SCG的频点。其中,一个小区添加的SCG的频点可以称为该小区的频点关联的辅助频点。当一个频点存在于上述频点列表时,表明终端设备驻留在该频点的小区时,网络侧有较大可能可以为该小区添加SCG。
在一种可能的实现方式中,终端设备中可以存储一个历史频点列表。该历史频点列表可以是终端设备基于自身的历史驻留经历而形成的。该历史频点列表用于指示所述终端设备对应的历史频点,以及所述终端设备对应的历史频点关联的辅助频点。其中,所述终端设备对应的历史频点可以表示终端设备驻留过且成功添加了SCG的小区的频点。
在一种可能的实现方式中,终端设备还可以存储一个云频点列表。该云频点列表可以是终端设备入网时,根据服务端根据推送的双连接频点组合而生成的。该云频点列表用于指示所述终端设备对应的云频点,以及所述终端设备对应的云频点关联的辅助频点。其中,所述终端设备对应的云频点可以表示同一运营商的其他终端设备驻留过且成功添加了SCG的小区的频点。在实施中,选择了相同公共陆地移动网(Public Land Mobile Network,PLMN)的终端设备可以认为是同一运营商的终端设备。
在实施中,终端设备可以仅存储历史频点列表和云频点列表中的一者;也可以既存储历史频点列表,又存储云频点列表;还可以将历史频点列表和云频点列表合并为一个频点列表进行存储,对此本申请实施例不做限制。

下面结合图4a和图5a分别对本申请实施例中涉及的历史频点列表和云频点列表的维护过程进行说明。
图4a示出本申请实施例中涉及的历史频点列表的维护过程示意图。该历史频点列表的维护过程可以由终端设备执行,例如图3a所示的手机200。如图4a所示,历史频点列表的维护过程包括:
步骤S400,成功驻留第一小区。
步骤S401,判断所述第一小区是否添加了SCG;若所述第一小区添加了SCG,则执行步骤S402,否则执行步骤S408。
终端设备成功驻留第一小区之后,终端设备可以判断网络侧是否为终端设备添加了SCG。在网络侧为终端设备添加了SCG的情况下,表明终端设备实现了LTE和NR的双连接。此时,终端设备可以执行历史频点列表中历史频点的增加操作。具体的增加操作可以参见后续的步骤S402至步骤S407。在网络侧未为终端设备添加SCG的情况下,表明终端仅连接了LTE,而 未连接NR。此时,终端设备可以执行历史频点列表中历史频点的删除操作。具体的删除过程可以参见后续的步骤S408至步骤S410。
步骤S402,判断历史频点列表中是否存在所述第一小区的第一频点;若历史频点列表中存在所述第一频点,则执行步骤S403,否则执行步骤S406。
在确定第一小区添加了SCG的情况下,终端设备可以判断历史频点列表中是否存在第一频点(即第一小区的频点)。在历史频点列表中存在第一频点的情况下,表明终端设备曾经在第一频点的小区驻留过,且网络侧为该小区添加了SCG。此时,终端设备可以通过步骤S403至步骤S405对历史频点列表中第一频点关联的辅助频点进行更新。在历史频点列表中不存在第一频点的情况下,表明终端设备没有在第一频点的小区驻留过,或者在第一频点的小区驻留时网络侧没有为该小区添加SCG。此时,终端设备可以执行步骤S406和步骤S407,对历史频点列表中第一频点,以及第一频点关联的辅助频点进行更新。
步骤S403,根据所述历史频点列表,确定所述第一频点关联的辅助频点。
步骤S404,判断所述第一频点关联的辅助频点中是否存在为所述第一小区添加的SCG的频点;若所述第一频点关联的辅助频点中存在所述第一小区添加的SCG的频点,则结束基于本次驻留经历对历史频点列表的维护,否则执行步骤S405。
步骤S405,将第一小区添加的SCG的频点作为所述第一频点关联的辅助频点存储在所述历史频点列表中。之后,结束基于本次驻留经历对历史频点列表的维护。
若第一频点关联的辅助频点中存在第一小区添加的SCG的频点,则终端设备无需对历史频点列表进行修改。若第一频点关联的辅助频点中不存在第一小区添加的SCG的频点,则终端设备可以将第一小区添加的SCG的频点确定为第一频点关联的辅助频点,从而与当前历史频点列表中第一频点关联的辅助频点共同保存在历史频点列表中。
步骤S406,将所述第一频点添加至所述历史频点列表中。
步骤S407,将第一小区添加的SCG的频点作为所述第一频点关联的辅助频点存储在所述历史频点列表中。之后,结束基于本次驻留经历对历史频点列表的维护。
步骤S408,判断历史频点列表中是否存在所述第一小区的第一频点;若历史频点列表中存在所述第一频点,则执行步骤S409,否则结束基于本次驻留经历对历史频点列表的维护。
在第一小区未添加SCG的情况下,终端设备同样需要判断历史频点列表中是否存在第一频点。在第一小区未添加SCG,且历史频点列表中不存在第一频点的情况下,终端设备无需对历史频点列表进行更新。在第一小区未添加SCG,且历史频点列表中存在第一频点的情况下,表明终端设备曾经驻留在第一频点的小区中,且网络侧为该小区添加了SCG,但是当前终端设备驻留在第一频点的小区中,但网络侧没有该小区添加了SCG。这可能是由于网络侧支持的双连接频点组合发生了变化而造成的。为了适应这种变化,在本申请实施例中,可以在第一小区未添加SCG,且历史频点列表中存在第一频点的情况下,执行步骤S409和步骤S410实现历史频点列表中历史频点及其关联的辅助频点的删除。
步骤S409,将所述第一小区确定为所述第一频点对应的单连接小区。
步骤S410,在所述第一频点对应的单连接小区的数量达到第一阈值的情况下,从所述历史频点列表中删除所述第一频点,以及所述第一频点关联的辅助频点。之后,结束基于本次驻留经历对历史频点列表的维护。
其中,第一频点对应的单连接小区可以表示频点为第一频点,且终端设备驻留时未添加 SCG的小区。在一个示例中,终端设备驻留在某个频点为第一频点的小区时,若网络侧确定该小区没有对应的SCG,进而没有为该小区添加SCG,则终端设备可以将该小区确定为第一频点对应的单连接小区。在又一示例中,终端设备驻留在某个频点为第一频点的小区时,若网络侧确定该小区有对应的SCG,但是由于终端支持的双连接频点组合与网络侧支持的双连接频点组合不匹配等原因,网络侧未成功为该小区添加SCG,则终端设备可以将该小区确定为第一频点对应的单连接小区。在实施中,终端设备驻留在某个频点为第一频点的小区时,还可以是由于其他原因造成了网络侧没有为该小区添加SCG时,终端设备均可以将该小区确定为第一频点对应的单连接小区。本申请实施例,对造成网络侧没有为小区添加SCG的原因不做限制。
需要说明的是,终端设备驻留在第一小区后,网络侧可以基于终端设备的业务量确定是否为第一小区添加SCG。在终端设备的业务量达到一定阈值(可根据需要进行设置)时,网络侧可以对终端设备支持的双频点连接组合和网络侧支持的双频点连接组合进行匹配,并在两者相匹配的情况下为第一小区添加SCG。网络侧可以在终端设备的业务量未达到一定阈值时,不执行对终端设备支持的双频点连接组合和网络侧支持的双频点连接组合进行匹配的操作,进而不进行SCG的添加。当然,终端设备驻留在第一小区后,网络侧还可以不考虑终端设备的业务量,直接对终端设备支持的双频点连接组合和网络侧支持的双频点连接组合进行匹配。
考虑到,终端设备驻留在第一小区后,网络侧可能会过一段时间再为其添加SCG。为了避免对是否添加SCG判断错误,在实施中,终端设备可以在不再驻留在第一小区的情况下,对驻留在第一小区期间是否添加SCG进行判断。这样,可以进一步提高历史频点列表的可靠性。
在第一频点对应的单连接小区的数量达到第一阈值的情况下,表明有多个第一频点的小区均没有成功添加SCG,这可能是由于网络侧不再支持在第一频点添加SCG而造成的。此时,终端设备可以所述历史频点列表中删除所述第一频点,以及所述第一频点关联的辅助频点。
在一种可能的实现方式中,终端设备可以在第一小区未添加SCG,且历史频点列表中存在第一频点的情况下,获取第一小区的标识,然后将第一小区的标识添加至第一频点对应的单连接小区列表中;在第一频点对应的单连接小区列表中的标识的数量达到第一阈值的情况下,从所述历史频点列表中删除所述第一频点。
其中,第一小区的标识可以用于识别唯一的第一小区,在一个实例中,第一小区的标识可以为第一小区的编号。第一阈值可以根据需要进行设置,例如,第一阈值可以根据运营商在某个区域(例如市、县等)配置的小区的数量进行设置。举例来说,在运营商在某个区域配置的小区的数量较大的情况下,第一阈值可以设置的较大,例如可以设置为5或者6等;在运营商在某个区域配置的小区的数量较小的情况下,第一阈值可以设置的较小,例如可以设置为3或者4等。第一阈值可以为静态值也可以为动态值。本申请实施例对第一小区的标识和第一阈值不做限制。可以理解的是,在实施中,终端设备可以为历史频点列表中的每个历史频点设置一个单连接小区列表,以判断各历史频点是否需要删除。
在本申请实施例中,终端设备在成功驻留小区之后,可以通过为该小区的频点添加成功添加SCG的标识,实现将该小区的频点存储在历史频点列表中,可以通过删除频点关联的添加SCG的标识,实现将某个频点从历史频点列表中删除。
在本申请实施例中,通过动态维护历史频点列表,使终端设备在搜网时可以优先针对曾经成功添加过SCG的频点发起小区搜索,提高终端设备优先驻留到能够添加SCG的小区的几率,从而使终端设备能够使用LTE和NR双连接来获取高速的数据服务,提升用户体验。
图4b示出历史频点列表的维护过程的一个示例。如图4b所示,假设终端设备1再次搜网之前经历过了图2所示的5次驻留经历。
终端设备1成功驻留频点为B3小区1后,终端设备1判断小区1添加了频点为N78的SCG,且历史频点列表中不存在小区1的频点B3。因此,终端设备1将频点B3添加至历史频点列表中,并将小区1添加的SCG的频点N78作为频点B3的辅助频点存储在历史频点列表中。此时,历史频点列表中存在的双连接频点组合为B3+N78。
终端设备1成功驻留频点为B3的小区2后,终端设备1判断小区1添加了频点为N79的SCG、历史频点列表中存在小区2的频点B3,且频点B3关联的辅助频点中不存在N79。因此,终端设备1将小区2添加的SCG的频点N79作为频点B3的辅助频点存储在历史频点列表中。此时,历史频点列表中存在的双连接频点组合为B3+N78和B3+N79。
终端设备1成功驻留频点为B8的小区3后,终端设备1判断小区3添加了频点为N78的SCG、历史频点列表中不存在小区3的频点B8。因此,终端设备1将频点B8添加至历史频点列表中,并将小区3添加的SCG的频点N78作为频点B8的辅助频点存储在历史频点列表中。此时,历史频点列表中存在的双连接频点组合为B3+N78、B3+N79以及B8+N78。
终端设备1成功驻留频点为B1的小区4后,终端设备1判断小区4未添加SCG,且历史频点列表中不存在小区4的频点B1。因此,终端设备1不修改历史频点列表。此时,历史频点列表中存在的双连接频点组合为B3+N78、B3+N79以及B8+N78。
终端设备1成功驻留频点为B5的小区5后,终端设备1判断小区5未添加SCG,且历史频点列表中不存在小区4的频点B5。因此,终端设备1不修改历史频点列表。此时,历史频点列表中存在的双连接频点组合为B3+N78、B3+N79以及B8+N78。
对比图4b和图2可知,在驻留经历4中,虽然小区4的系统消息中配置有ULR,但是根据本申请实施例提供的方法,终端设备1没有将B1添加至历史频点列表中。
图4c示出历史频点列表的维护过程的一个示例。终端设备1在图4b的基础上,又经历了图4c所示的驻留经历6至驻留经历8。也就是说,终端设备1在经历驻留经历6之前,其历史频点列表中存在的双连接频点组合为B3+N78、B3+N79以及B8+N78。假设第一阈值为3。
在驻留经历6中,终端设备1驻留小区6且未添加SCG,小区6的频点为B3。在终端设备1成功驻留小区6后,终端设备1判断小区6未添加SCG,且历史频点列表中存在小区6的频点B3。因此,终端设备1将小区6确定为频点B3的单连接小区。由于此时频点B3的单连接小区的数量未达到3,因此,终端设备1不修改历史频点列表。
在驻留经历7中,终端设备1驻留小区7且未添加SCG,小区7的频点为B3。在驻留经历8中,终端设备驻留小区8且未添加SCG,小区8的频点为B3。在终端设备1成功驻留小区7后,终端设备1将小区7确定为频点B3的单连接小区。由于此时频点B3的单连接小区的数量未达到3,因此,终端设备1修改不修改历史频点列表。在驻留经历8中,终端设备1驻留小区8且未添加SCG,小区8的频点为B3。在终端设备1成功驻留小区8后,终端设备1将小区8确定为频点B3的单连接小区。由于此时频点B3的单连接小区的数量达到了3,因此,终端设备1删除历史频点列表中的频点B3,以及频点B3关联的辅助频点N78和N79。此 时,历史频点列表中存在的双连接频点组合为B8+N78。
图5a示出本申请实施例中云频点列表的维护过程示意图。如图5a所示,云频点列表的维护过程包括:
步骤S500,第二终端设备成功驻留第三小区。
第三小区可以为任意一个小区,第三小区可以与第一小区相同,也可以与第一小区不同,本申请实施例对第三小区不做限制。第二终端设备成功驻留第三小区,表明第二终端设备入网成功,此时第二终端设备已经结束了本轮搜网工作。
步骤S501,第二终端设备获取当前选择的PLMN的第一标识和历史频点列表中的第一双连接频点组合。
PLMN的标识可以用于区分不同的运营商。不同的终端设备在不同运营商下支持的双连接频点组合可能不同,不同的运营商在同一位置配置的双连接频点组合也可能不同。
第一标识可以用于表示一个终端设备当前选择的PLMN的标识。考虑到第二终端设备表示与所述第一终端设备选择了PLMN的终端设备。这里第二终端设备获取的第一标识与在后续步骤S505中第一终端设备获取的第一标识实际上是相同的。第二终端设备形成其历史频点列表可以参照图4a所示形成其历史频点列表的过程,这里不再赘述。可以理解的是,第二终端设备对应的历史频点列表用于指示第二终端设备对应的历史频点,以及第二终端设备对应的历史频点关联的辅助频点。其中,第二终端设备对应的历史频点可以表示第二终端设备驻留过且成功添加了SCG的小区的频点,辅助频点可以表示添加的SCG的频点。
第一双连接频点组合可以用于表示从一个终端设备的历史频点列表中获取的历史频点和辅助频点的关联关系。这里,第二终端设备获取的第一双连接频点组合即为第二终端设备从其对应的历史频点列表中获取的历史频点和辅助频点的关联关系。
步骤S502,第二终端设备向服务端上报所述第一标识和所述第一双连接频点组合。
步骤S503,服务端关联存储所述第一标识和所述第一双连接频点组合。
在一种可能的实现方式中,步骤S503可以包括:若接收到所述第一标识以及所述第一双连接频点组合的次数满足存储条件,则关联存储所述第一标识和所述第一双连接频点组合。
其中,所述存储条件包括:在第一时间间隔内接收到所述第一标识以及所述第一双连接频点组合的次数占接收到双连接频点组合的总次数的比例大于第二阈值。
在实施中,第一时间间隔可以表示服务端存储标识与双连接频点组合的周期。第一时间间隔可以根据选择各运营商的用户数量设置。在一个示例中,第一时间间隔可以为1天或者1周等,对此本申请实施例不做限制。第二阈值可以根据需要进行设置。例如,第二阈值可以根据运营商下的用户数量设置。举例来说,对于用户数量较大的运营商而言,对应的第二阈值可以设置的较小,例如可以设置为5%;对于用户数量较小的运营商而言,对应的第二阈值可以设置的相对较大,例如可以设置为8%等。这样,可以避免少量情况带来的不准确问题。
在一种可能的实现方式中,步骤S503还可以包括:若接收到第一标识以及所述第一双连接频点组合的次数满足删除条件,则将所述第一标识以及所述第一双连接频点组合的关联关系删除。
其中,所述删除条件包括:在第二时间间隔内接收到所述第一标识以及所述第一双连接频点组合的次数小于第三阈值。
在实施中,第二时间间隔可以表示服务端清理存储的标识与双连接频点组合的周期。第 二时间间隔可以根据选择各运营商的用户数量设置。在一个示例中,第二时间间隔可以为1天或者1周等,对此本申请实施例不做限制。第三阈值可以根据需要进行设置,例如第三阈值可以根据第二时间间隔的时长确定,在第二时间间隔的时长较大的情况下,第三阈值可以设置的较大,在第二时间间隔的时长较小的情况下,第三阈值可以设置的较小,在一个示例中,第三阈值可以设置为1或者3等。这样,可以提高服务端存储的双连接频点组合的准确性。
需要说明的是,在实施中,第一时间间隔和第二时间间隔可以相同也可以不同,对此本申请实施例不做限制。
步骤S504,在成功驻留第二小区的情况下,第一终端设备获取当前选择的PLMN的第一标识。
其中,第二小区可以表示任意的一个小区,第二小区与第一小区、第三小区可以为同一小区,也可以为不同的小区,本申请实施例对第二小区不做限制。第一终端设备成功驻留第二小区,表明第一终端设备已经入网成功,此时第一终端设备已经结束了本轮搜网工作。
步骤S505,第一终端设备向服务端发送入网消息,所述入网消息中包括所述第一标识。
步骤S506,服务端向第一终端设备推送所述第一标识关联的第一双连接频点组合。
步骤S507,第一终端设备根据接收到的第一双连接频点组合生成云频点列表。
在一种可能的实现方式中,步骤S506可以包括:在所述第一双连接频点组合与所述第一终端设备支持的双连接频点组合匹配情况下,将所述第一双连接频点组合中的历史频点作为所述第一终端设备对应的云频点添加至所述云频点列表中,并将所述第一双连接频点组合中的历史频点关联的辅助频点作为所述云频点关联的辅助频点存储在所述云频点列表中。
这样,相较于直接将第一双连接频点组合中的历史频点作为所述第一终端设备对应的云频点添加至所述云频点列表中,并将所述第一双连接频点组合中的历史频点关联的辅助频点作为所述云频点关联的辅助频点存储在所述云频点列表中,更加符合第一终端设备的能力,可以提高第一终端设备成功进行双连接的概率。
在本申请实施例中,通过动态维护云频点列表,使终端设备在之后搜网时可以优先针对同一个运营商中其他终端设备曾经成功添加过SCG的频点发起小区搜索,提高终端设备优先驻留到能够添加SCG的小区的几率,从而使终端设备能够使用LTE和NR双连接来获取高速的数据服务,提升用户体验。
图5b示出云频点列表的维护过程的一个示例。以终端设备1、终端设备2和终端设备3为图5a中的第二终端设备,以终端设备4为图5a中的第一终端设备为例。
如图5b所示,终端设备1的第一标识为PLMN1,终端设备1的历史频点列表中存在的双连接频点组合为B3+N78和B8+N78。终端设备1可以将PLMN1、B3+N78和B8+N78上报至服务端。同理,终端设备2可以将PLMN2、B1+N1、B1+N78上报至服务端,终端设备3可以将PLMN3、B1+N7上报至服务端。服务端可以对接收到的标识和双连接频点组合进行关联存储。服务端中的存储可以参照图5b。
图5c示出云频点列表的维护过程的一个示例。图5c示出了终端设备4在图5b的基础上入网后的处理过程。
如图5c所示,第1步,终端设备4成功驻留第三小区。第2步,终端设备4通过向服务端发送入网消息向服务端上报PLMN1。第3步,服务端向终端设备4推送PLMN1对应的双连 接频点组合:B3+N78、B8+N78。第4步,终端设备4根据接收到的双连接频点组合生成云频点列表。该云频点列表中包括云频点B3和B8,云频点B3关联的辅助频点N78,云频点B8关联的辅助频点N78。
假设终端设备4的支持的双连接频点组合为B3+N78和B8+N1。终端设备4将自身支持的双连接频点组合和云频点列表中的双连接频点组合进行匹配。具体的,终端设备4将自身支持的B3+N78和B8+N1与云频点列表中的:B3+N78、B8+N78进行匹配,得到终端只有驻留在频率为B3的小区中才能添加SCG。因此,在第5步,终端设备4断网后再次搜网时,可以优先针对频点B3进行小区搜索,使得终端设备4可以优先驻留到频率为B3的小区的几率,从而使终端设备4能够使用LTE和NR双连接来获取高速的数据服务,提升用户体验。
图6示出根据本申请实施例的小区搜索的方法的流程图。所述方法可以应用于第一终端设备。如图6所示,所述方法包括:
步骤S601,获取目标频点。
其中,目标频点为成功添加辅小区组SCG的频点。在一种可能的实现方式中,所述目标频点包括所述第一终端设备对应的历史频点和/或云频点,所述第一终端设备对应的历史频点表示所述第一终端设备驻留过且成功添加了SCG的小区的频点,所述第一终端设备对应的云频点表示第二终端设备驻留过且成功添加了SCG的小区的频点,所述第二终端设备表示与所述第一终端设备选择了相同公共陆地移动网PLMN的一个或多个终端设备。
在本申请实施例中,第一终端设备可以根据图4a所示的维护过程获得历史频点列表,进而确定终端设备历史频点。第一终端设备可以根据图5a所示的过程获得云频点列表,然后根据获得的云频点列表获取云频点。
在一种可能的实现方式中,在获取目标频点之前,第一终端设备可以获取待搜索频点,以在本步骤中,从待搜索频点中,获取所述目标频点。其中,待搜索频点可以表示第一终端设备将要进行小区搜索的频点,第一终端设备可以获取一个或多个待搜索频点。这样,在实施中,第一终端设备可以判断待搜索频点中是否有存于上述历史频点列表中的频点,若待搜索频点中的某个频点存在于该历史频点列表中,则该频点可以被确定为目标频点。第一终端设备还可以判断待搜索频点中是否有存在于上述云频点列表中的频点,若待搜索频点中的某个频点存在与该云频点列表中,则该频点可以被确定为目标频点。
在一个示例中,第一终端设备可以将历史驻留过的频点作为待搜索频点。在实施中,第一终端设备可以将当前时间之前的一段时间(例如,一天、一周或者等)内驻留过的频点作为待搜索频点。此时,待搜索频点之间的排列顺序可以根据待搜索频点的驻留时间确定。在进行小区搜索时,驻留时间在前的待搜索频点排在驻留时间在后的待搜索频点之前。
在又一示例中,第一终端设备可以将第一终端设备中预设的频点作为待搜索频点。具体的,第一终端设备中预设的频点可以为由运营商预先设置在第一终端设备中安装的用户身份识别(Subscriber Identity Module,SIM)卡中频点。此时,待搜索频点之间的排列顺序也是预先设置的,即待搜索频点之间存在预设顺序。
在另一示例中,第一终端设备可以进行扫频,将扫频结果得到的频点作为待搜索频点。其中,扫频可以是全频段扫频,也可以是指定频段扫频,对此本申请实施例不做限制。此时,待搜索频点之间的排列顺序可以按照接收信号强度指示(Received Signal Strength Indication,RSSI)等指标确定。举例来说,RSSI较大的待搜索频点排在RSSI较小的待搜 索频点之后。
在实施中,第一终端设备可以先将历史驻留过的频点作为待搜索频点,然后在所有历史驻留过的频点都没有搜索到小区的情况下,将预设的频点作为待搜索频点,最后在所有预设的频点都没有搜索到小区的情况下,进行扫频,并将扫频得到的频点作为待搜索频点。当然,待搜索频点可以通过其他方式获得。本申请实施例对获取待搜索频点的方式以及获取的待搜索频点的数量不做限制。
在实施中,在存在目标频点的情况下,第一终端设备可以针对目标频点进行小区搜索;在不存在目标频点的情况下,第一终端设备可以按照待搜索频点的排列顺序依序进行小区搜索。这样,实现了第一终端设备小区搜索时对目标频点的优先搜索。
考虑到目标频点可以有一个或多个。在存在多个目标频点的情况下,第一终端设备可以按照待搜索频点的搜索顺序,确定目标频点搜索顺序。也就是说,当目标频点为第一终端设备历史驻留过的频点时,针对目标频点进行小区搜索时,目标频点之间的搜索顺序可以根据驻留时间确定。驻留时间在前的目标频点排在驻留时间在后的目标频点之前。当目标频点为第一终端设备中预设的频点时,针对目标频点进行小区搜索时目标频点之间的搜索顺序可以根据预设顺序确定。当目标频点为扫频结果中的频点时,针对目标频点进行小区搜索时目标频点之间的搜索顺序可以根据RSSI等指标确定。例如,RSSI较大的目标频点排在RSSI较小的目标频点之前。
在一种可能的实现方式中,在针对目标频点的小区搜索均失败的情况下,第一终端设备可以针对除目标频点以外的频点(例如待搜索频点中除目标频点以外的频点)进行小区搜索。
在一种可能的实现方式中,步骤S602可以包括:在存在目标频点,且所述目标频点以及所述关联的辅助频点与所述第一终端设备支持的双连接频点组合相匹配的情况下,针对所述目标频点进行小区搜索。这样,可以提高第一终端设备驻留目标频点的小区后,实现双连接的可能性。
在一种可能的实现中,在目标频点中既存在历史频点又存在云频点的情况下,第一终端设备可以先针对历史频点进行小区搜索,再针对云频点进行小区搜索。考虑到历史频点是根据第一终端设备自身的驻留经历获得的,而云频点是根据同一运营商下的其他第一终端设备的驻留经历获得的,因此,第一终端设备驻留在频点为历史频点的小区时,能够成功添加SCG的可能性更大。因此,先针对历史频点进行小区搜索,再针对云频点进行小区搜索可以提升第一终端设备实现双连接的可能性,提升用户体验。
步骤S603,驻留在搜索到的小区中。
由于在存在目标频点的情况下,第一终端设备会针对目标频点进行小区搜索;在不存在目标频点的情况下,第一终端设备才按照待搜索频点的排列顺序依序进行小区搜索。因此,在存在目标频点的情况下,第一终端设备很有可能驻留在频点为目标频点的小区,也就是说,第一终端设备优先对目标频点进行小区搜索,这提高了第一终端设备优先驻留到能够添加SCG的小区的几率,从而使第一终端设备能够使用LTE和NR双连接来获取高速的数据服务,提升用户体验。
下面结合具体的场景对本申请实施例提供的小区搜索的方法进行说明。
场景一:
假设终端设备1在运营商1下支持的双连接频点组合为B8+N78、B3+N78。运营商1在小 区1配置的双连接频点组合为B8+N1、B3+N78,运营商1在小区2配置的双连接频点组合为B8+N78,B3+N78。
终端设备1在小区1开机搜网时,在小区1的覆盖范围内移动,随着频点B3小区和频点B8小区的信号强度变化,终端设备1先后驻留过频点B3的小区和频点B8的小区。在终端设备1驻留在频点为B3的小区时,网络侧为其添加了频点为N1的SCG,在终端设备1驻留在频点为B8的小区时,网络侧未为其添加SCG。至此终端设备1中生成的历史频点列表中存在的双连接频点组合为:B3+N78。因此,之后,终端设备1会优先针对频率B3进行小区搜索。
假设终端设备1在空前状态移动到小区2的覆盖范围内,重新开机。此时,B8小区的信号强度略高于B3小区。
由于终端设备1学习到了B3可以添加SCG,而B8无法添加SCG。因此,终端设备1在小区2的覆盖范围搜网时会优先选择B3小区进行驻留。由于小区2配置的双连接频点组合B8+N78与终端设备1支持的双连接频点组合相匹配,因此终端设备1在小区2的覆盖范围搜网时,如果驻留在B8小区也可以添加SCG。这与终端设备1在小区1中学习到的结果不同。
若采用本申请实施例提供的小区搜索的方法,虽然B8小区的信号强度略高于B3小区,终端设备1根据学习结果优先选择驻留在B3小区。这就导致了,终端设备1虽然能够使用LTE和NR双连接来获取高速的数据服务,但是并没有驻留在信号更好且能实现ENDC的小区中。
在实际应用过程中,在终端设备1成功驻留B3小区之后,在B8小区满足切换条件的情况下,终端设备1仍然会正常切换到B8小区进行驻留。由于终端设备1能够成功驻留在B3小区时,表明B3小区的通信质量是满足门限要求的,终端设备1驻留在B3小区时,用户对通信质量是可以接受的,再加上终端设备1后续切换到了B8小区进行驻留,在B3小区驻留的时间是有限的,因此,对用户体验造成的影响也比较小。
由于终端设备1在搜网时,优选B3,B3也可添加ENDC同时信号是满足判断条件的,业务体验不会很差,所以此问题影响较小。
另外,同一运营商网络的双连接频点组合,在同一城市基本是相同的,变化频率很低,所以此问题出现的概率较小。相比整体方案的收益来说,问题影响可接受。
场景二:
网侧支持的双连接频点组合为:B8+N1、B3+N78。
终端设备支持的双连接频点组合为:B8+N78,B3+N78。
在相关技术中,B8和B3均为支持ENDC的频点。若B8小区的信号强度大于B3小区的信号强度,终端设备会选择优先驻留在B8。在终端设备成功驻留B8之后,由于终端设备上报的支持的双连接频点组合B8+N78与网络侧支持的双连接频点组合B8+N1不匹配,网络侧不会为B8添加SCG。因此,终端设备成功驻留B8之后不能享受5G高速率,导致用户体验较差。
在本申请实施例中,终端设备通过自学习已经识别了B8无法添加ENDC,B3可以添加ENDC。因此,搜网时,如果发现B8小区的信号强度大于B3小区的信号强度,但是B3小区的信号强度大于保护门限(例如参考信号接收功率(Reference Signal Receiving Power,RSRP)大于-100dB,参考信号接收质量(Reference Signal Receiving Quality,RSRQ)大于-15dB)),终端设备会优先选择B3小区进行驻留,从而使终端设备能够使用LTE和NR双连接来获取高速的数据服务,提升用户体验。如果发现B8小区的信号强度大于B3小区的信号,且B3小区 的信号强度小于或者等于保护门限,终端设备会优先选择B8小区进行驻留。如果发现B8小于的信号强大小于或者等于B3小区的信号强度,则终端设备会优先选择B3小区进行驻留。
由此可见,在本申请实施例中,在B3小区的信道质量大于保护门限的情况下,尽管其相对于B8小区的信道质量较差,仍然可以使终端设备优先驻留在B3小区,以使终端设备能够使用LTE和NR双连接来获取高速的数据服务,提升用户体验。
