本申请主张在2018年3月19日在中国提交的中国专利申请号No.201810226184.1的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信领域，尤其涉及一种资源选择方法、用户设备和网络侧设备。
背景技术
在无线通信系统中，在用户设备(UserEquipment，UE)和网络侧设备通信期间，由于移动性，连接态UE可能从一个基站(当前与该UE连接的基站)的覆盖区域移到另一个基站的覆盖区域，此时UE需要将原有无线信道转换至新的无线信道，即完成切换(Handover)。
长期演进(Long Term Evolution，LTE)中，切换失败主要是因为UE不能及时收到源基站下发的切换命令。在新空口(New Radio，NR)中，小区部署更为密集，小区覆盖范围相对较小，这会导致UE更为频繁的执行切换。此外，在波束赋形(beamforming)系统中，且UE工作在高频段(高于6GHz)时，相对于LTE系统源基站和UE之间的无线信道质量会变化很快，如果在UE移动到另一个基站的覆盖区域内还没有收到源基站下发的切换命令就会导致切换失败。因此，在NR中，继续沿用LTE的切换方法会导致切换失败概率提升。为了缓解这一问题，第五代移动通信技术(5th-Generation，5G)中引入了条件切换(conditional Handover)的方式，条件切换是指基站基于UE上报的测量结果为UE准备一个或多个候选目标小区，并向UE发送条件切换命令(包含候选目标小区列表，候选目标小区对应的切换触发条件，候选目标小区对应的资源配置等)，UE接收到条件切换命令后不会立即执行小区切换，而是在确定候选小区满足预设切换触发条件后才执行小区切换。
目前，条件切换的过程如图1所示，UE在完成切换之前与源节点连接， 首先源节点向UE发送测量配置，UE按照接收到该测量配置执行测量并向源节点反馈测量报告，源节点基于该测量报告决定是否为UE准备一个或多个候选小区以及执行条件切换操作。
在源节点决定执行条件切换操作，该切换过程包括下述主要步骤：步骤1，源节点向候选节点1和候选节点2发送切换请求信息；步骤2，候选节点1和候选节点2向源节点反馈切换确认信息；步骤3，源节点向UE发送条件切换命令；步骤4，UE基于条件切换命令评估候选节点1和候选节点2是否满足预设条件，并选择一个满足预设条件的候选节点进行切换；步骤5，UE向选择的候选节点(候选节点1)发起随机接入过程；步骤6，UE向选择的候选节点(候选节点1)发送切换完成信息；步骤7，UE选择的候选节点(候选节点1)向源节点发送数据包状态请求，源节点给UE未选择的候选节点(候选节点2)发送取消条件切换命令；步骤8，UE未选择的候选节点(候选节点2)给源节点发送条件切换取消确认命令。
然而，在上述场景中，当UE在评估候选小区是否满足预设条件时，若一个或多个触发条件同时满足且对应于已满足的触发条件存在多个资源配置时，UE如何从多个配置中选择一个通信资源配置来进行切换，仍亟待解决。
发明内容
本公开实施例的目的是提供一种资源选择方法、用户设备和网络侧设备，在UE确定一个或多个触发条件同时满足且对应于已满足的触发条件存在多个资源配置时，为用户从多个资源配置中选择一个资源配置提供一种解决方案。

第二方面，提出了另一种资源选择方法，该方法包括：
发送RRC重配置消息，所述RRC重配置消息中携带有预设优先级准则， 用于用户设备在确定满足触发条件的资源配置存在多个时，基于所述预设优先级准则，从所述多个资源配置中选择目标资源配置。
第三方面，提出了一种用户设备，包括：
确定单元，用于确定满足触发条件的资源配置，所述资源配置对应候选小区；
选择单元，用于若确定所述满足触发条件的资源配置存在多个，则基于预设优先级准则，从所述多个资源配置中选择目标资源配置。
第四方面，提出了一种网络侧设备，包括：
发送单元，用于发送RRC重配置消息，所述RRC重配置消息中携带有预设优先级准则，用于用户设备在确定满足触发条件的资源配置存在多个时，基于所述预设优先级准则，从所述多个资源配置中选择目标资源配置。
第五方面，提出了一种用户设备，包括：
处理器；以及
被配置为存储计算机可执行指令的存储器，所述可执行指令在被执行时使所述处理器执行如第一方面所述的方法。
第六方面，提出了一种计算机可读存储介质，所述计算机可读存储介质存储一个或多个程序，所述一个或多个程序当被包括多个应用程序的电子设备执行时，使得所述电子设备执行如第一方面所述的方法。
第七方面，提出了一种网络侧设备，包括：
处理器；以及
被配置为存储计算机可执行指令的存储器，所述可执行指令在被执行时使所述处理器执行如第二方面所述的方法。
第八方面，提出了一种计算机可读存储介质，所述计算机可读存储介质存储一个或多个程序，所述一个或多个程序当被包括多个应用程序的电子设备执行时，使得所述电子设备执行如第二方面所述的方法。

具体实施方式
为了使本技术领域的人员更好地理解本公开中的技术方案，下面将结合本公开实施例中的附图，对本公开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公开一部分实施例，而不是全部的实施 例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都应当属于本公开保护的范围。说明书以及权利要求中使用的“和/或”表示连接对象至少其中之一。
本公开的技术方案，可以应用于各种通信系统，例如：全球移动通讯系统(Global System of Mobile communication，GSM)，码分多址(Code Division Multiple Access，CDMA)系统，宽带码分多址(Wideband Code Division Multiple Access，WCDMA)，通用分组无线业务(General Packet Radio Service，GPRS)，长期演进(Long Term Evolution，LTE)/增强长期演进(Long Term Evolutionadvanced，LTE-A)，新空口(New Radio，NR)等。

如背景技术中所述，UE在评估候选小区是否满足条件切换中的预设条件时，若确定满足触发条件的候选小区中存在多个资源配置时，相关技术还没有给出UE如何从多个满足触发条件的资源配置中选择出一个资源配置进行切换的解决方案。因此急需一种解决方案来应对这一问题，这将是本公开一个或多个实施例要解决的问题。
图2是本公开的一个实施例提供的资源选择方法的实施流程示意图，图2的方法由用户设备执行，该方法包括：
步骤101，确定满足触发条件的资源配置，该资源配置对应候选小区；
其中，资源配置为候选基站(也就是候选小区对应的基站)为用户设备预留的资源，该资源可以包括但不限于用户设备随机接入该基站所需的资源， 以及用户设备接入该基站后正常工作所需的资源。该资源配置可以是网络侧设备发送的，可以携带在RRC重配置消息中。网络侧设备也就是当前与用户设备连接的源节点，在向用户设备发送测量配置之后，用户设备按照接收到该测量配置执行测量并向源节点反馈测量报告，当源节点基于该测量报告决定为用户设备执行条件切换操作时，便可以向该用户设备发送RRC重配置消息。
因此，在确定满足触发条件的资源配置之前，用户设备还可以接收来自网络侧设备的RRC重配置消息，该RRC重配置消息中可以包括但不限于多个候选小区的标识、多个候选小区对应的触发条件和多个候选小区对应的资源配置。其中，触发条件可以包括下述中的一种或多种的组合：候选小区的信道测量结果高于或等于第一预设门限值；源小区的信道测量结果小于或等于第二预设门限值，该源小区是当前为用户设备服务的小区；候选小区的信道测量结果与源小区的信道测量结果的差值大于或等于第三预设门限值；候选小区的信道测量结果大于或等于第四预设门限值，源小区的信道测量结果小于或等于第五预设门限值。
其中，与上述信道测量结果相关的参数可以包括参考信号接收功率(Reference Signal Received Power，RSRP)、参考信号接收质量(Reference Signal Received Quality，RSRQ)和信干噪比(Signal to Interference plus Noise Ratio，SINR)中的一种或多种的组合。
以候选小区包括小区1、小区2、小区3和小区4为例，且信道测量结果包括RSRP，其中，小区1对应的触发条件包括小区1的信道测量结果高于或等于第一预设门限值，小区2对应的触发条件包括UE的源小区的信道测量结果小于或等于第二预设门限值，小区3对应的触发条件包括小区3的信道测量结果与UE的源小区的信道测量结果的差值大于或等于第三预设门限值，小区4对应的触发条件包括小区4的信道测量结果大于或等于第四预设门限值，且UE的源小区的信道测量结果小于或等于第五预设门限值。
在上述场景中，假设在某一时刻t1，UE通过获取源小区和候选小区，也就是源小区、小区1、小区2、小区3和小区4的信道测量结果(即RSRP的具体测量数值)，若确定该信道测量结果满足了小区1、小区2和小区3的触 发条件，也就是说，在t1时刻，小区1的RSRP高于或等于第一预设门限值k1，小区2的RSRP小于或等于第二预设门限值k2，小区3的RSRP与UE的源小区的RSRP的差值大于或等于第三预设门限值k3，而小区4的RSRP小于第四预设门限值k4，且UE的源小区的RSRP小于或等于第五预设门限值k5，显然小区1、小区2和小区3在t1时刻分别满足其对应的触发条件，而小区4在t1时刻并不满足其对应的触发条件，因此，可以确定满足触发条件的资源配置，该资源配置也就对应小区1、小区2和小区3。
步骤102，若确定满足触发条件的资源配置存在多个，则基于预设优先级准则，从多个资源配置中确定目标资源配置。
可选的，预设优先级准则包括小区相关优先级准则、信道测量相关优先级准则、时延优先级准则和丢包率优先级准则中的至少一种。其中，小区相关优先级准则包括下述至少一种：频点优先级准则，比如可以预先设置第一频点f1的优先级大于第二频点f2的优先级、第二频点f2的优先级大于第三频点f3的优先级，...，即f1>f2>f3>...>fn；小区标识优先级准则，比如可以预先设置小区1的优先级大于小区2的优先级、小区2的优先级大于小区3的优先级，...，即小区1>小区2>小区3>…>小区n。
应理解，时延优先级准则可以为时延越低，其所对应的资源配置的优先级也就越高，丢包率优先级准则可以为丢包率越低，其多对应的资源配置的优先级也就越高。
可选的，信道测量相关优先级包括下述至少一种：触发条件优先级准则；信道测量结果优先级准则。其中，触发条件优先级准则可以根据实际需求预先设置，与触发条件优先级准则相关的触发条件包括下述至少一种：触发条件1，候选小区的信道测量结果高于或等于第一预设门限值；触发条件2，源小区的信道测量结果小于或等于第二预设门限值；触发条件3，候选小区的信道测量结果与源小区的信道测量结果的差值大于或等于第三预设门限值；触发条件4，候选小区的信道测量结果大于或等于第四预设门限值，源小区的信道测量结果小于或等于第五预设门限值。
应理解，由于触发条件1仅仅是确定了候选小区的信道测量结果的具体情况，触发条件2仅仅是确定了源小区的信道测量结果的具体情况，而触发 条件3和触发条件4既确定了候选小区的信道测量结果的具体情况也确定了源小区的信道测量结果的具体情况，因此，触发条件3和触发条件4相较于触发条件1和触发条件2而言其限制条件更多更具体，那么满足触发条件3或触发条件4的候选小区也就能够更好地为用户设备的接入而准备比如随机接入所需的资源等资源配置。
因此，在实际应用中，触发条件3或触发条件4的优先级可以高于触发条件1或触发条件2的优先级，比如可以设置触发条件优先级准则为：触发条件3的优先级高于触发条件4的优先级，触发条件4的优先级高于触发条件1的优先级，触发条件1的优先级高于触发条件2的优先级；或者还可以是触发条件4的优先级高于触发条件3的优先级，触发条件3的优先级高于触发条件2的优先级，触发条件2的优先级高于触发条件1的优先级。应理解，这里所列举的触发条件优先级准则只是一种示例性的参考，在实际应用中可根据实际需求进行具体设置，本公开实施例对此将不做具体限定。
可选的，上述所述的预设优先级准则可以是基于协议约定或者也可以是网络配置的。当预设优先级准则是基于网络配置时，在基于预设优先级准则，从多个资源配置中选择目标资源配置之前，还可以预先接收无线资源控制(Radio Resource Control，RRC)重配置消息，该RRC重配置消息中携带有预设优先级准则，在实际应用中，由于预设优先级准则可以携带在专用RRC重配置消息中下发给用户设备，也可以通过携带在RRC重配置消息的容器(container)中下发给用户设备，因此，接收RRC重配置消息具体来说，可以接收专用RRC重配置消息，该RRC重配置消息中携带有预设优先级准则；或者，还可以将该优先级准则放置在网络侧设备下发给用户设备的的RRC重配置消息的容器中，这样用户设备可以接收RRC重配置消息，该RRC重配置消息的容器中携带有预设优先级准则。
也就是说，预设优先级准则既可以携带在专用RRC重配置消息中，也可以放置在网络侧设备下发给用户设备的RRC重配置消息的容器中，用户设备可以通过这两种方式来获取预设优先级准则。
应理解，在确定满足触发条件的资源配置之前，应预先获取这些满足触发条件的资源配置，具体可以接收来自于网络侧设备的RRC重配置消息，该 RRC重配置消息中包括多个候选小区的标识、多个候选小区对应的触发条件和多个候选小区对应的资源配置。本公开实施例所提供的资源选择方法的具体应用场景可以包括单连接切换场景(场景1)，双连接架构下辅小区组(Secondary Cell Group，SCG)添加(addition)场景(场景2)以及双连接架构下SCG切换(change)场景(场景3)。
其中，双连接架构包括两个小区组：主小区组(Master Cell Group，MCG)和SCG，其中MCG对应于网络侧的主节点(Master Node，MN)，而SCG对应于网络侧的辅节点(Secondary Node，SN)。
下面针对用户设备处于以上这三种不同的场景，对本公开实施例提供的资源选择方法进行详细介绍：
场景1，当用户设备处于单连接场景中时，上述下发RRC重配置消息的网络侧设备为源节点，如图3所示，为本公开实施例提供的资源选择方法应用在场景1中的实现流程示意图，在图3所示的场景中，包括用户设备、源节点、候选节点1和候选节点2，具体切换过程包括下述主要步骤：
步骤11，源节点向用户设备发送测量配置，用户设备按照接收到的测量配置执行测量并向源节点反馈测量报告，源节点接收到反馈的测量报告后，可以基于该测量报告决定是否要为用户设备准备一个或多个候选小区并执行条件切换操作，当源节点基于测量报告决定要为用户设备准备一个或多个候选小区并执行条件切换操作后，便可以执行步骤12；
步骤12，源节点向候选节点发送条件切换请求，由于本场景中的候选节点包括候选节点1和候选节点2，因此，步骤12可以包括：步骤12-1，向候选节点2发送条件切换请求1，以及步骤12-2，向候选节点1发送条件切换请求2；
步骤13，候选节点对源节点发送的条件切换请求进行条件切换响应，具体来说，步骤13可以包括：步骤13-1，候选节点2对源节点发送的条件切换请求1进行条件切换响应1，以及步骤13-2，候选节点1对源节点发送的条件切换请求2进行条件切换响应2；
步骤14，源节点向用户设备发送RRC重配置消息，该RRC重配置消息中包括多个候选小区的标识(也就是候选节点1和候选节点2的标识)、多个 候选小区对应的触发条件和多个候选小区对应的资源配置；
步骤15，对RRC重配置消息中的候选小区的资源配置进行评估，确定满足触发条件的资源配置；
步骤16，若确定同时存在多个满足触发条件的资源配置，则可以基于预设优先级准则从这些多个资源配置中选择一个资源配置作为目标资源配置。
步骤17，在用户设备基于预设优先级准则选择了目标资源配置后，便可以向源节点发送切换指示；
步骤18，用户设备向选择的目标资源配置发起随机接入过程，进行切换操作，具体切换过程在这里将不再赘述。
场景2，当用户设备处于双连接架构下SCG添加的场景中时，上述下发RRC重配置消息的网络侧设备为主节点，如图4所示，为本公开实施例提供的资源选择方法应用在场景2中的实现流程示意图，在图4所示的场景中，包括用户设备、主节点、候选辅节点1和候选辅节点2，具体切换过程包括下述主要步骤：

步骤22，向候选辅节点发送条件SN添加请求，由于本场景中的候选辅节点包括候选辅节点1和候选辅节点2，因此，步骤22可以包括：步骤22-1，向候选辅节点2发送条件SN添加请求1，以及步骤22-2，向候选辅节点1发送条件SN添加请求2；
步骤23，候选辅节点对主节点发送的条件SN添加请求进行条件SN添加响应，具体来说，步骤23可以包括：步骤23-1，候选辅节点2对主节点发送的条件SN添加请求1进行条件SN添加响应1，以及步骤23-2，候选辅节点1对主节点发送的条件SN添加请求2进行条件SN添加响应2；
步骤24，主节点向用户设备发送RRC重配置消息，该RRC重配置消息中包括多个候选辅节点的标识(也就是候选辅节点1和候选辅节点2的标识)、 多个候选辅节点对应的触发条件和多个候选辅节点对应的资源配置；
步骤25，用户设备对条件SN添加命令中的候选节点的资源配置进行评估，确定满足触发条件的资源配置；
步骤26，若用户设备确定同时存在多个满足触发条件的资源配置，则可以基于预设优先级准则从这些多个资源配置中选择一个资源配置作为目标资源配置。
步骤27，在用户设备基于预设优先级准则选择了目标资源配置后，便可以向主节点发送切换指示；
步骤28，用户设备向选择的目标资源配置发起随机接入过程，进行切换操作。
场景3，当用户设备处于双连接架构下SCG切换的场景中时，此时用户设备连接的源节点则包括主节点和源辅节点，那么上述下发RRC重配置消息的网络侧设备可以为主节点，也可以为源辅节点，当上述下发RRC重配置消息的网络侧设备为源辅节点时，该源辅节点与用户设备之间建立了信令无线承载3SRB3，也就是说，该源辅节点可以直接与用户设备之间进行信令交互。如图5所示，为本公开实施例提供的资源选择方法应用在场景3中的实现流程示意图，在图5所示的场景中，包括用户设备、主节点、源辅节点、候选辅节点1和候选辅节点2，具体切换过程包括下述主要步骤：
步骤31，主节点向用户设备发送测量配置，用户设备按照接收到的测量配置执行测量并向主节点反馈测量报告，主节点接收到反馈的测量报告后，可以基于该测量报告决定是否要为用户设备准备一个或多个候选辅节点并执行条件切换操作，当主节点基于测量报告决定要为用户设备准备一个或多个候选辅节点并执行条件切换操作后，便可以执行步骤32；
步骤32，主节点向候选辅节点发送条件切换请求，由于本场景中的候选辅节点包括候选辅节点1和候选辅节点2，因此，步骤32可以包括：步骤32-1，向候选辅节点2发送条件切换请求，以及步骤32-2，向候选辅节点1发送条件切换请求；
步骤33，候选辅节点对主节点发送的条件切换请求进行条件切换响应，具体来说，步骤33可以包括：步骤33-1，候选辅节点2对主节点发送的条件 切换请求进行条件切换响应，以及步骤33-2，候选辅节点1对主节点发送的条件切换请求进行条件切换响应；
步骤34，主节点向用户设备发送RRC重配置消息，该RRC重配置消息中包括多个候选辅节点的标识(也就是候选辅节点1和候选辅节点2的标识)、多个候选辅节点对应的触发条件和多个候选辅节点对应的资源配置；
可选地，当源辅节点与用户设备之间建立了信令无线承载3SRB3之后，源辅节点与用户设备之间能够直接进行信令交互时，上述步骤31～步骤34中的主节点也可以替换为源辅节点来执行。
步骤35，对RRC重配置消息中的候选辅节点的资源配置进行评估，确定满足触发条件的资源配置；
步骤36，若确定同时存在多个满足触发条件的资源配置，则可以基于预设优先级准则从这些多个资源配置中选择一个资源配置作为目标资源配置。
步骤37，在用户设备基于预设优先级准则选择了目标资源配置后，便可以向源节点发送切换指示；
步骤38，用户设备向选择的目标资源配置发起随机接入过程，进行切换操作。
本公开实施例中，能够确定满足触发条件的资源配置，其中资源配置对应于候选小区，在确定满足触发条件的资源配置存在多个时，则可以基于预设优先级准则从多个资源配置中选择目标资源配置，比如可以基于小区相关优先级准则、信道测量相关优先级准则、时延优先级准则和丢包率优先级准则中的一种或多种优先级准则来从多个资源配置中选择目标资源配置，从而使得UE能够切换到该目标资源配置上。
