本公开文本实施例涉及通信技术领域，特别是指一种小区选择或重选方法、小区切换参数的设置方法及装置。
背景技术
现有技术方案，比如LTE(长期演进)中，针对空闲态用户和连接态用户，分别定义了频率优先级事件以满足对不同频率网络上的负荷进行规划的需要。比如1.9GHz频段和2.6GHz频段小区可以采用不用的频率优先级，以配合适当的小区重选门限，从而可以对1.9GHz频段和2.6GHz频段小区间的空闲态用户分布进行整体控制，而在连接态，通过测量事件(Event，比如A2，A3，A4和A5)的和测量报告的配置，采取与空闲态相同的策略，则可以保证用户在不同频率网络上的合理分布。但在一些场景下，比如高铁覆盖专用网络和普通公网覆盖网络交叠区域等。上述频率优先级的设置存在一些问题：
1.即使高铁专网和普通公网采用不同的频率优先级，为了保证专网用户能够快速选择/返回专用，专网频率通常配置较高的优先级，但这个优先级对于所有终端设备用户都适用，导致专网覆盖区域的普通公网用户/地面用户也会大量驻留在专网上，导致专网资源被普通公网用户大量占用；
2.高铁专网和普通公网采用相同的频率，公网和专网小区无法区分频率优先级，导致终端设备在专网和公网小区间频繁重选，公网用户难以区分专网小区和公网小区，导致专网覆盖区域的普通公网用户/地面用户也会大量驻留在专网上，导致专网资源被普通公网用户大量占用。

具体实施方式
下面将结合本公开文本实施例中的附图，对本公开文本实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开文本一部分实施例，而不是全部的实施例。基于本公开文本中的实施例，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，都属于本公开文本保护的范围。
为使本公开文本实施例要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
第一实施例
如图1所示，本公开文本的第一实施例提供一种小区选择或重选方法，所述方法应用于终端设备。所述方法包括：
步骤11，获取至少一个小区的速度优先级，以及终端设备的移动速度等级；以及
步骤12，根据所述速度优先级和所述移动速度等级进行小区选择或小区重选。
网络侧设备为小区分别配置小区速度优先级，并通过速度优先级标识来指示小区速度优先级。例如小区速度优先级可分为高速、中速、低速，也可分为1级，2级和3级等等。具体的，高铁专网小区的小区速度优先级可设置为高速，或1级，则高铁专网小区优先为高速移动的终端设备服务。而普通公网小区的小区速度优先级可设置为中速或低速，也可设置为2级或3级，则普通公网小区优先为中速或低速移动或相对固定的终端设备服务。
终端设备侧可以基于对自己移动速度的估算，来确定其自身的移动速度等级，同样分为高速，中速和低速，或分为1级，2级和3级，终端设备侧根据自身的移动速度等级来选择与之匹配的速度优先级的小区来驻留。
具体而言，终端设备可以根据小区的速度优先级来判断小区是适用于服务高速移动用户的专网小区还是适用与服务一般移动速度的普通公网小区；则终端设备可以根据自身的移动速度等级来选择匹配的小区进行驻留，避免高铁专网资源被一般移动速度的用户大量占用。
具体的，本公开文本的第一实施例中，所述速度优先级中，还可以包括速度优先级范围信息，所述速度优先级范围信息用于标识小区的速度优先级的服务范围；则步骤12包括：
步骤121，将所述移动速度等级和所述至少一个小区的速度优先级进行比对，从所述至少一个小区中选择速度优先级与所述移动速度等级匹配的小 区作为候选小区，其中，所述终端设备处于所述候选小区的速度优先级的服务范围内；
步骤122，在所述候选小区中进一步进行小区选择或小区重选。
具体的，步骤122包括：
步骤1221，在所述候选小区中，按照小区的频率优先级进一步进行小区选择或小区重选。
在本公开文本的第一实施例中，终端设备对多个小区进行一次小区排除，确定候选小区。确定的候选小区可以为一个也可以为多个，该类候选小区的速度优先级均与终端设备的移动速度等级匹配。确定候选小区之后，还需根据频率优先级对多个候选小区再一次进行小区排除，从而确定目标小区，并对目标小区进行驻留。
进一步的，本公开文本的上述实施例中步骤121包括：
步骤1211，分别获取至少一个小区的速度优先级和所述终端设备的移动速度等级的级别差值；以及
步骤1212，确定最小的级别差值对应的小区为候选小区，所述候选小区的速度优先级与所述终端设备的移动速度等级匹配。
可选的，若级别差值包括：0、1、2；则此时最小的级别差值为0，即小区的速度优先级与终端设备的移动速度等级相同，级别差值为0对应的小区为候选小区；若级别差值包括1、2；则此时最小的级别差值为1，则小区的速度优先级与终端设备的移动速度等级相近，并确定级别差值为1对应的小区为候选小区。
具体的，当所述级别差值等于0时，所述候选小区的速度优先级与所述终端设备的移动速度等级完全匹配；以及
当所述级别差值不等于0时，向上匹配时，所述候选小区的速度优先级级别高于所述终端设备的移动速度等级级别；或者，向下匹配时，所述候选小区的速度优先级级别低于所述终端设备的移动速度等级级别。
具体的，当所述级别差值不等于0时，根据预先约定或者根据网络侧设备指示来确定向上匹配或者向下匹配。
需要说明的是，当级别差值不等于0时，终端设备的移动速度等级的可 能高于候选小区速度优先级，也可能低于候选小区速度优先级。例如当级别差值等于1时，设终端设备的移动速度等级为中速(或移动速度等级为2级)，小区的速度优先级可能是高速(1级)，也可能是低速(3级)。终端设备在确定候选小区的过程中，可以按照预设规则优先选择高于移动速度等级的小区，或者也可以优先选择低于移动速度等级的小区，或者高于移动速度等级的小区和低于移动速度等级的小区均选择。
进一步需要说明的是，该预设规则可以由终端设备预先设定，也可以由网络侧设备预先配置，在此不作具体限定。
此外，若终端设备的当前邻区配置信息中所有邻区的速度优先级与终端设备的移动速度等级的级别差值均大于所述最小的级别差值，且终端设备接收当前小区信号强度高于预设门限时，终端设备无需启动搜索小区的速度优先级与终端设备的移动速度等级的级别差值更小的小区的过程。
综上，网络侧设备引入基于速度维度的优先级列表，网络侧设备的小区可以将各自设置为适用于高速移动的终端设备的小区、适用于中速移动的终端设备的小区或者适用于低速移动的终端设备的小区，在此不作具体限定。速度优先级，可简单设置为高速小区或低速小区；也可设置为高速小区、中速小区或低速小区，也可设置为1级，2级或3级等形式来标志不同的速度优先级。终端设备则引入基于终端设备移动速度等级的归属优先级判断，终端设备基于对自己移动速度的估算，决定自己优先驻留的小区应该是高速优先级小区还是低速优先级小区，然后结合网络侧的各小区的速度优先级标识/优先级列表来选择对应小区来驻留。
需要说明的是，终端设备结合自身的移动速度等级和网络侧的各小区的速度优先级进行小区选择。与现有技术相比，终端设备需要在基于频率优先级进行小区选择过程之前完成自己的移动速度等级与各小区中的速度优先级进行匹配的过程。
例如，用户在高铁上，则终端设备的移动速度优先级为高速。此时终端设备进行小区选择或者小区重选的过程如下：
小区A、小区B高铁专网小区，小区C为高速公路小区，小区D为普通公网小区。终端设备获取周围小区的速度优先级，其包括：小区A，速度优 先级为高速；小区B，速度优先级为高速；小区C，速度优先级为中速；小区D，速度优先级为低速。
终端设备结合自身的移动速度优先级和各个小区的速度优先级，从而确定小区A和小区B为候选小区。终端设备进一步根据小区A和小区B的频率优先级进行小区选择。其中，频率优先级的选择过程为现有技术，此处不进行详细描述。
通过本公开文本的第一实施例提供的小区选择或重选方法可以使得终端设备能够识别高铁专网和普通公网，从而可以有效控制在不同移动速度的空闲态用户高铁专网和普通公网的分布或驻留，避免公网用户大量驻留在高铁专网上而导致专网资源被普通公网用户大量占用，降低终端设备脱网或体验下降的概率。
第二实施例
如图2所示，本公开文本的第二实施例提供一种小区切换参数的设置方法，所述方法应用于网络侧设备。所述方法包括：
步骤21，根据终端设备的移动速度等级以及小区的速度优先级，设置触发终端设备事件上报或切换流程的参数。该参数还用于终端设备进行小区选择或重选。
本公开文本的第二实施例提供的小区切换参数的设置方法应用于连接态的终端设备，即连接态的终端设备在移动过程中触发终端设备事件上报或切换流程的参数。对于连接态的终端设备，对于不同速度优先级的小区之间的切换设置不同的切换参数。比如当终端设备需从服务小区切换至一目标小区时，若目标小区和服务小区属于相同的速度优先级时，遵循常规的事件触发。若目标小区和服务小区属于不同的速度优先级时，则采用不同的事件触发或引入特定的迟滞。
具体的，本公开文本的第二实施例中步骤21包括：
步骤211，设置每个移动速度等级分别与所有速度优先级之间的映射关系。
具体的，设终端设备的移动速度等级包括：高速、中速和低速。小区的速度优先级包括：高速、中速和低速。相应的，映射关系具体包括：1)高速 终端设备-高速小区；2)高速终端设备-中速小区；3)高速终端设备-低速小区；4)中速终端设备-高速小区；5)中速终端设备-中速小区；6)中速终端设备-低速小区；7)低速终端设备-高速小区；8)低速终端设备-中速小区；9)低速终端设备-低速小区。
步骤211，设置不同的关系对，具体包括：
1)高速终端设备-高速小区to中速小区；2)高速终端设备-中速小区to高速小区；3)高速终端设备-高速小区to低速小区；4)高速终端设备-低速小区to高速小区；5)高速终端设备-中速小区to低速小区；6)高速终端设备-低速小区to中速小区；7)中速终端设备-高速小区to中速小区；8)中速终端设备-中速小区to高速小区；9)中速终端设备-高速小区to低速小区；10)中速终端设备-低速小区to高速小区；11)中速终端设备-中速小区to低速小区；12)中速终端设备-低速小区to中速小区；13)低速终端设备-高速小区to中速小区；14)低速终端设备-中速小区to高速小区；15)低速终端设备-高速小区to低速小区；16)低速终端设备-低速小区to高速小区；17)低速终端设备-中速小区to低速小区；18)低速终端设备-低速小区to中速小区。
步骤212，为每个映射关系对分别设置触发终端设备的事件上报或切换流程的参数，其中映射关系对是指2个映射关系之间。
本步骤分别为上述9个映射关系对设置参数，并且，所述触发终端设备的事件上报或切换流程的参数包括：触发终端设备的事件上报或切换流程的速度扩展因子和/或触发终端设备事件上报或切换流程的迟滞参数。
具体的，在与终端设备相关的mobility State parameters(移动状态参数)中的q-HystSF中引入反映终端设备的移动速度等级和目标小区速度优先级映射关系的参数。
例如：迟滞参数的定义如下：
Figure PCTCN2018071768-appb-000001
Figure PCTCN2018071768-appb-000002
其中，sf-High-High-to-High中，第一个移动速度标识(High)表示终端设备的当前移动速度等级；第二个移动速度标识(High)表示终端设备的当前服务小区的速度优先级；第三个移动速度标识(High)表示目标小区的速度优先级，即终端设备需切换到目标小区。
再例如，速度扩展因子的定义如下：
Figure PCTCN2018071768-appb-000003
其中，sf-High-High-to-High中，第一个移动速度标识(High)表示终端设备的当前移动速度等级；第二个移动速度标识(High)表示终端设备的当前服务小区的速度优先级；第三个移动速度标识(High)表示目标小区的速度优先级，即终端设备需切换到目标小区。
综上，利用本公开文本的第二实施例小区切换参数的设置方法设置的小区切换参数能够使得终端设备不仅依据自身的移动速度进行小区切换，还结合目标小区的速度优先级进行小区切换，从而提高切换效率。具体的，终端设备从高速小区切换到高速小区时，则迟滞量较小。而终端设备从高速小区切换到低速小区时，则迟滞量较大等等。进一步需要说明的是，这里的切换参数设置方法同样可以用于小区选择或重选参数设置。
第三实施例
为了更好的实现上述目的，如图3所示，本公开文本的第三实施例还提供一种小区选择或重选装置，所述装置应用于终端设备。所述装置包括：
获取模块31，用于获取至少一个小区的速度优先级，以及终端设备的移动速度等级；以及
小区选择模块32，用于根据所述速度优先级和所述移动速度等级进行小区选择或小区重选。
具体的，在本公开文本的第三实施例的所述速度优先级中，还可以包括速度优先级范围信息，所述速度优先级范围信息用于标识小区的速度优先级的服务范围。所述小区选择模块包括：

具体的，本公开文本的第三实施例中当所述级别差值等于0时，所述候选小区的速度优先级与所述终端设备的移动速度等级完全匹配；
当所述级别差值不等于0时，向上匹配时，所述候选小区的速度优先级级别高于所述终端设备的移动速度等级级别；或者，向下匹配时，所述候选小区的速度优先级级别低于所述终端设备的移动速度等级级别。
具体的，本公开文本的第三实施例中，当所述级别差值不等于0时，根据预先约定或者根据网络侧设备指示来确定向上匹配或者向下匹配。
具体的，本公开文本的第三实施例中，若终端设备的当前邻区配置信息中所有邻区的速度优先级与终端设备的移动速度等级的级别差值均大于所述最小的级别差值，且终端设备接收当前小区信号强度高于预设门限时，终端设备无需启动搜索小区的速度优先级与终端设备的移动速度等级的级别差值更小的小区的过程。
综上，通过本公开文本的第三实施例提供的小区选择装置可以使得终端设备能够识别高铁专网和普通公网，从而可以有效控制在不同移动速度的空闲态用户接入高铁专网和普通公网，避免公网用户大量驻留在高铁专网上而导致专网资源被普通公网用户大量占用，降低拖网或体验下降的概率。
需要说明的是，本公开文本的第三实施例提供的小区选择装置是能够执行上述第一实施例提供的小区选择或重选方法的装置，则上述小区选择或重选方法的所有实施例均适用于小区选择装置，且均能达到相同或相似的有益效果。

具体的，本公开文本的第四实施例中所述设置模块包括：

第二设置子模块，用于为每个所述映射关系对分别设置触发终端设备的事件上报或切换流程的参数，其中映射关系对是指2个映射关系之间。
具体的，本公开文本的第四实施例中所述触发终端设备的事件上报或切换流程的参数包括：触发终端设备的事件上报或切换流程的速度扩展因子和/或触发终端设备的事件上报或切换流程的迟滞参数。
综上，利用本公开文本的第四实施例小区切换参数的设置装置设置的小区切换参数能够使得终端设备不仅依据自身的移动速度进行小区切换，还结合目标小区的速度优先级进行小区切换，从而提高切换效率。具体的，终端设备从高速小区切换到高速小区时，则迟滞量较小。而终端设备从高速小区切换到低速小区时，则迟滞量较大等等。
