具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请实施例相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请实施例的一些方面相一致的装置和方法的例子。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”及“若”可以被解释成为“在……时”或“当……时”或“响应于确定”。
请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个终端11以及若干个基站12。
其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment，UE)。或者，终端11也可以是无人飞行器的设备。或者，终端11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，终端11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通 信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC系统。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，终端11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体 (Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户网络侧设备(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
如图2所示，在区域1，期望仅增强移动带宽(enhance Mobile BroadBand，eMBB only)UE优先驻留在f1，因为f2上支持即超高可靠与低时延通信(The Ultra Reliable Low Latency Communications Conference，URLLC)，要优先服务URLLC UE。但在区域2，仅增强移动带宽UE优先驻留在f2，因为f2上带宽大，优先服务eMBB业务。
对区域1UE，网络通过专用信令给仅增强移动带宽UE配置一个固定的频率优先级f1>f2。当UE由区域1移动到区域2后，该专用优先级不再适用，现有技术无法解决该问题。因此需要一种能够适应UE slice类型的优先级方式。
在以下实施例中UE又可以称之作为终端。
如图3所示，本实施例提供一种小区重选方法，其中，应用于终端中，包括：
S110：接收频点及所述频点所支持网络切片组合的第一优先级信息；
S120：根据所述第一优先级信息，进行小区重选。
在本申请实施例中，该方法可以应用于各种支持网络切片的终端中，该终端可包括：常规终端、物联网终端、车载终端或者轻型终端等。所述常规终端可包括手机等，再例如，长期演进(Long Term Evolution，LTE)终端等。
在本申请实施例中，终端会从基站接收第一优先级信息，此处的第 一优先级信息是频点及该频点所支持网络切片组合的优先级信息，指示了频点及该频点所支持网络切片共同的优先级。
在本申请实施例中，基站会向终端下发第一优先级信息，终端在进行小区重选时就不再仅是根据小区优先级或者频点优先级来进行小区重选，而是会考虑频点和频点支持的网络切片组合的优先级所对应的第一优先级信息进行重选，从而终端所驻留小区的重选，从而减少终端所驻留小区不能提供终端所需或所支持网络切片导致的通信质量达不到预期的现象，提升了通信质量。
在一些实施例中，所述方法还包括：
根据切片信息确定所述频点支持的网络切片，其中，所述切片信息包括：单一网络切片选择辅助信息、切片类型信息或服务类型信息。
在本申请实施例中所述切片信息可包含任意能够指示网络切片的信息，包括但不限于标识信息。
例如，所述切片信息可包含：单一网络切片选择辅助信息、切片类信息型或服务类型信息。
单一网络切片选择辅助信息可作为网络切片标识的一种。
切片类型信息指示的是网络切片的类型。
服务类型信息可指示网络切片所能够提供服务的类型。
不同所述服务类型对应于不同业务类型。
在一些通信网络中可提供支持不用业务类型的网络切片。如图4所示，三种不同的业务类型(关键(critical)MTC类型业务，比如健康监测设备的数据，大规模(massive)MTC类型业务，比如抄表类业务，MBB类型业务，比如视频类业务)，划分到三个网络切片，各个网络切片的计费策略，安全策略，服务质量(Quality of Service，QoS)策略等都可能不同。一个网络切片里出现大规模的业务拥塞不会影响到其它网 络切片里业务的正常运转。
在具体进行小区重选时，所述S120可包括：
根据终端的服务小区的频点及频点所支持网络切片的优先级、邻小区的频点及频点所支持的网络切片的优先级、终端的服务小区的信号质量和邻小区的信号质量，确定小区重选的目标小区。而终端的服务小区的频点及频点所支持网络切片的优先级、邻小区的频点及频点所支持的网络切片的优先级都可以由前述第一优先级信息指示。此处的邻小区包括但不限于：同系统同频小区、同系统异频小区及跨系统小区中的任意与终端的服务小区相邻的一个或多个小区。
例如，优先选择优先级高且信号质量好的小区作为小区重选的目标小区。
在一些实施例中，所述S120可包括：
针对同系统异频小区和同系统同频小区的重选，根据所述第一优先级信息，确定具有相同优先级的同系统异频小区和同系统同频小区的信号质量；
确定所述信号质量最大的所述同系统异频小区或所述同系统同频小区为小区重选的目标小区。
同系统异频小区为：同一个通信系统内支持不同频点的小区。
同系统同频小区为：同一个通信系统内支持相同频点的小区。
此处的同一个通信系统可为采用相同通信制式的系统，例如，3G系统、4G系统或5G系统为不同的通信系统。
此处的同系统异频小区和同系统同频小区都是服务小区的邻小区。由于属于同一系统，则可能第一优先级信息所对应的频点和频点所支持的网络切片组合的优先级相同。
在第一优先级指示的优先级相同时，则根据信号质量确定小区重选 的目标小区。
该信号质量为小区信号质量，包括但不限于：终端的接收信号强度、接收信号功率或信干噪比等。
选择信号质量最大的小区作为小区重选的目标小区，如此，一方面确保了重选的小区能够给终端提供其所需或能够使用网络切片，同时根据信号质量选择目标小区，能够确保无线信号的传输质量。
在一些实施例中，所述S120可包括：
针对同系统异频小区、同系统同频小区及异系统小区的重选，根据所述第一优先级信息，确定同系统异频小区、同系统同频小区及异系统小区中，是否存在优先级高于所述终端的服务小区的优先级的小区；
当存在高于所述终端的服务小区的优先级的小区时，确定高于所述终端的服务小区的优先级且信号质量高于第一门限的小区为小区重选的目标小区。
此处的异系统小区为不同通信系统的小区。例如，若服务小区为4G小区，异系统小区可包括5G小区、3G小区或2G小区等不同通信代数的小区。
在服务小区的邻小区包含同系统异频小区、同系统同频小区及异系统小区时，这些小区都可以作为小区重选的备选小区。此时，可以根据第一优先级信息，选择优先级高于服务小区的其中一个作为小区重选的服务小区。
在本申请实施例中，若根据第一优先级信息确定的优先级高于服务小区的同系统异频小区、同系统同频小区或异系统小区的优先级高于服务小区的优先级，会选择优先级高于终端的服务小区且信号质量高于第一门限的小区作为小区重选的目标小区。
在一些实施例中，所述S120可包括：
针对同系统异频小区、同系统同频小区及异系统小区的重选，根据所述第一优先级信息，确定同系统异频小区、同系统同频小区及异系统小区中，是否存在优先级存在高于或等于所述终端的服务小区的优先级的小区；
当不存在高于或等于所述终端的服务小区的优先级的小区时，若所述终端的服务小区的信号质量低于第二门限，且所述同系统异频小区、所述同系统同频小区及所述异系统小区存在信号质量高于第三门限的小区时，将信号质量高于所述第三门限的小区作为小区重选的目标小区。
此处的第三门限小于所述第二门限。此处所述第二门限和所述第三门限可相等，不局限于第三门限小于第二门限。
在一些实施例中，所述第三门限可略低于所述第一门限。但是具体实现时不限于第三门限低于第一门限，如此，存在优先级高于或等于服务小区的优先级时，可以放松一定对信号质量的要求，如此实现信号质量和所提供网络切片选择平衡。
在一些实施例中，所述S120可包括：
当所述终端的服务小区的信号质量大于第四门限时，根据所述第一优先级信息，确定同系统同频小区支持的网络切片的优先级是否高于所述终端的服务小区支持的网络切片的优先级；
当同系统同频小区支持的网络切片的优先级高于所述终端的服务小区支持的网络切片的优先级时，进行同系统同频小区的信号质量测量；
根据所述信号质量测量的结果，选择所述同系统同频小区为所述小区重选的目标小区。
在本申请实施例中与小区的信号质量测量相关，若服务小区的信号质量较好，即服务小区的信号质量大于第四门限，此处的第四门限可等于前述的第一门限，但不限于等于前述的第一门限。
此时就看同系统同频小区是否有优先级高于服务小区的，如果有才进行同系统同频小区的信号质量测量，减少不必要的信号测量，减少终端因为邻小区的同频测量所产生的功耗。如果没有同系统同频小区的优先级高于服务小区，就可以不用进行同系统同频小区的信号质量测量。
如果进行信号质量测量，就根据信号质量测量的结果，确定小区重选的目标小区。
在本申请实施例中，根据信号质量测量的结果，选择小区重选的目标小区，可以将信号质量测量的信号质量作为一个参考因素，具体在进行终端的小区重选时，还会考虑到不同小区的负载均衡等现象。
在一些实施例中，所述S120可包括：
当所述终端的服务小区的信号质量大于第五门限时，根据所述第一优先级信息，确定同系统异频小区和异系统小区的优先级是否高于所述终端的服务小区的优先级；
当同系统异频小区和异系统小区的优先级高于所述终端的服务小区的优先级时，进行同系统异频小区和所述异系统小区的信号质量测量；
根据所述信号质量测量的结果，选择所述同系统异频小区或所述异系统小区为所述小区重选的目标小区。及
此处的第五门限可等于前述的第四门限，也可以不等于前述的第四门限。
在一些实施例中，所述根据信号质测量的结果，选择所述同系统异频小区或所述异系统小区为所述小区重选的目标小区，可包括：
根据信号质量测量的结果，选择信号质量最高的同系统异频小区或所述异系统小区为所述小区重选的目标小区。
在另一些实施例中，所述根据信号质测量的结果，选择所述同系统异频小区或所述异系统小区为所述小区重选的目标小区，可包括：
根据信号质量测量的结果，选择信号质量大于预定门限且负载率低于负载门限的同系统异频小区或所述异系统小区为所述小区重选的目标小区。
在一些实施例中，若根据第一优先级信息确定出有同系统异频小区或异系统小区的优先级高于服务小区，则会进行异频信号的测量，若否，则可以不进行同系统异频小区和所述异系统小区的异频信号的测量，从而减少不必要的信号测量，降低终端功耗。
由于异系统一般采用的是不同的频段，从而异系统小区一般与服务小区所支持的频点不同。故异系统小区属于异频小区。
在一些实施例中，所述方法还包括：当同系统异频小区和异系统小区的优先级低于所述终端的服务小区的优先级时，不进行所述同系统异频小区或所述异系统小区的信号质量测量。
在一些实施例中，如图5所示，所述方法还包括：
S410：接收所述终端的服务小区广播的系统信息；
S420：根据所述系统信息携带邻小区的切片信息，确定邻小区的频点所支持的网络切片。此处，所述第一优先级信息至少可指示：所述邻小区的频点及所述频点支持的网络切片组合的优先级。
在本实施例中终端的服务小区内会广播系统消息，从终端的服务小区的系统消息中可以获得邻小区频点所支持的网络切片的切片信息，从而终端无需从邻小区接收邻小区的频点所支持网络切片的切片信息。
例如，所述S410可包括以下至少之一：接收终端的服务小区广播的同系统同频小区重选系统消息，其中，所述同系统同频小区重选消息，携带有同系统同频小区的切片信息；
接收终端的服务小区广播的同系统异频小区重选系统消息，其中，所述同系统异频小区重选消息，携带有同系统异频小区的切片信息；
接收终端的服务小区广播的异系统小区重选系统消息，其中，所述异系统小区重选系统消息，携带有异系统小区的切片信息。
所述同系统同频小区重选系统消息可为选择同系统同频小区的重选信息的系统消息，例如，可携带有重选门限等信息。
所述同系统异频小区重选系统消息可为选择同系统异频小区的重选信息的系统消息，例如，可携带有重选门等信息。
所述异系统小区重选系统消息可为选择异系统异频小区的重选信息的系统消息，例如，可携带有重选门等信息。
在一些实施例中，所述同系统同频小区重选系统消息包括但不限于系统消息块(System Information Block，SIB)3。所述同系统异频小区重选系统消可包括但不限于SIB4。所述异系统小区重选系统消息包括但不限于SIB5。
在一些实施例中，所述S120可包括
根据所述第一优先级信息，确定所述系统消息携带的切片信息所对应同系统异频小区为小区重选的备选小区；
和/或，
根据所述第一优先级信息，确定所述系统消息携带的切片信息所对应异系统小区为小区重选的备选小区。
在根据第一优先级信息进行小区重选，将哪些小区作为基于第一优先级信息进行小区重选的备选小区，是根据服务小区所发送的系统消息中被携带有切片信息的同系统同频小区、同系统异频小区及异系统小区，从而减少在所有小区内进行小区重选导致的重选到不合适的小区上。
在一些实施例中，所述方法还包括：
接收所述终端的服务小区广播的第一指示；其中，所述第一指示，用于指示在所述终端的服务小区内广播的系统消息是否能够携带所述切 片信息；
所述根据所述系统信息携带的切片信息，确定邻小区的频点支持的网络切片，包括：
当接收到所述第一指示，且所述系统消息未携带所述邻小区的切片信息时，确定所述邻小区与所述终端的服务小区的频点支持的网络切片相同。
在本申请实施例中，所述第一指示可为广播的任意消息，例如，广播的系统消息等。
在服务小区内广播第一指示，此处的第一指示会指示服务小区是否会在系统消息中携带有邻小区的频点所支持网络切片的切片信息。
即便终端接收到了第一指示，但是在服务小区内接收到的系统消息也可能携带有切片信息，也可能未携带有切片信息。若在接收到第一指示，且未携带有切片信息时，就确定邻小区的频点所支持网络切片与服务小区的频点所支持网络切片相同。若系统消息中携带有切片信息，则根据切片信息确定邻小区的频点所支持网络切片的切片信息。
在一些实施例中，所述方法还包括：
在所述终端的服务小区支持第二指示的广播时，接收所述终端的服务小区广播的所述第二指示，其中，所述第二指示，用于指示所述终端的服务小区的频点和所述邻小区的频点，支持的网络切片不同；
若接收到所述第一指示且接收到所述第二指示时，根据所述系统消息携带的所述邻小区的切片信息，确定所述邻小区频点支持的网络切片。在一些实施例中，在服务小区内还会广播第二指示。第二指示是用于指示服务小区的频点和邻小区的频点支持不同的网络切片。
若接收到第一指示且未接收到第二指示，且系统消息未携带有邻小区的切片信息，则确定所述邻小区与所述终端的服务小区的频点支持的 网络切片相同。
在另一些实施例中，所述方法还包括：
若未接收到所述第二指示，确认所述邻小区的频点所支持的网络切片与所述终端的服务小区的频点所支持的网络切片不同。即未接收到第二指示，可默认邻小区的频点所支持的网络切片与服务小区的频点所支持的网络切片相同。
例如，所述若未接收到所述第二指示，确认所述邻小区的频点所支持的网络切片与所述终端的服务小区的频点所支持的网络切片不同，包括：
在接收到第一指示、未接收到所述第二指示时且所述系统消息未携带的所述邻小区的切片信息，确定所述邻小区频点支持的网络切片。与所述终端的服务小区的频点支持的网络切片相同。
在一些实施例中，所述第一指示和/或第二指示都可以仅包含1个比特，可以在不同时间的系统消息中广播。
在一些实施例中，所述方法还包括：
在所述终端的服务小区不支持所述第二指示的广播时，不根据所述系统消息确定邻小区的频点所支持的网络切片。
UE在服务小区内未接收到基站广播的第二指示时，就不根据服务小区的系统消息确定邻小区的频点所支持的网络切片。例如，此时，UE可以根据邻小区发送的切片信息，确定邻小区的频点所支持的网络切片。
在一些实施例中，所述接收频点及频点所支持网络切片组合的第一优先级信息，包括：
在所述终端的跟踪区更新(Tracking Area Update，TAU)或无线网络通知区更新(Radio Access Network Area Update，RAU)时，接收所述第一优先级信息。
TAU的更新涉及核心网所在区域的更新，而RAU的更新是涉及无线网所在区域的更新。一般而言TAU所对应的跟踪区(Tracking Area，TA)比RAU所对应的通知区(Notification Area，NA)的面积更大。
在TAU或RAU的时候，接收第一优先级信息，如此在该TA或通知区内涉及小区重选时，就可以采用该第一优先级信息实现小区重选。
例如，在TAU或RAU的完成消息或确认消息中携带有所述第一优先级信息，如此，终端在接收到所述TAU或RAU的完成消息或确认消息时，就完成了所述第一优先级信息的接收。
在一些实施例中，所述接收频点及频点所支持网络切片组合的第一优先级信息，包括：
在所述终端释放无线资源控制(Radio Resource Control，RRC)连接时，接收携带有所述第一优先级信息的RRC释放信息。
在一些实施例中，终端通过RRC连接释放消息释放RRC连接从而退出连接态，进入到空闲态或者非激活态。如此，再次进入到连接态时，就会进行小区重选，如此，就可以及时根据RRC连接释放消息中携带的第一优先级信息进行与网络切片关联的小区选择。
在本申请实施例中，频点与频点所支持网络切片所对应的第一优先级信息，没有通过专门的信息来发送，而是利用已有流程中所使用信息来接收，具有与现有技术兼容性强，且减少终端不必要的接收。且在TAU、RAU及连接释放消息中接收第一优先级信息，可以在下次进行小区重选时就可以立马用上，从而减少延误。
当UE支持多种网络切片时，UE优先接入哪个网络目前是由网络通过频率优先级控制的。频率优先级的选取由网络侧决定。然而，网络并不一定了解终端各个网络切片的发生频率，那么就可能给UE配置的频率上支持的网络切片发生频率是比较低的，这就会导致每当UE由高频率的 网络切片业务时，终端都先得接入别的频率，然后再切换到支持该网络切片的频率上，造成不必要的切换。
在一些实施例中，所述方法还包括：
上报终端支持的网络切片的第二优先级信息；其中，所述第二优先级，用于确定频点及所述频点支持的网络切片或网络切片组合的第一优先级信息。
在一些情况下，终端因为根据自身的软硬件能力可以支持特定的网络切片，或者，不支持特定的网络切片。在另一些情况下，终端因为通信业务的订购状况，支持某一个或多个网络切片，和/或不支持某一个或多个网络切片。
在这种场景下，终端根据自身能力与网络切片的匹配程度，自身的业务发生频次和/或付费情况等，可以给自身支持的网络切片配置优先级，该优先级由第二优先信息来指示。此处的第二优先级信息是终端所支持网络切片的优先级。
终端将自身支持的网络切片的第二优先级信息上报之后，网络侧(例如，基站)会根据终端上报的网络切片的第二优先级信息，针对该终端配置频点和频点所支持网络切片组合的第一优先级信息。
通常情况下，频点的优先级和频点所支持的网络切片所对应第二优先级信息所指示优先级的高低是正相关的。这种正相关可包括正比例相关。
如此，支持不同网络切片的终端，针对同一个频点及其所支持的网络切片具有不同的第一优先级信息，实现UE粒度的第一优先级信息的配置。
在一些实施例中，所述方法还包括：
根据网络切片上业务发生频率，确定所述终端支持的网络切片或网 络切片组合的第二优先级信息。
业务发生频率可包含单位时间内使用某一业务的次数；或者，单位时间内某一个业务所产生流量。
在一些实施例中，所述频点的优先级，与所述频点支持的网络切片优先级正相关；或者，所述频点的优先级，与所述频点及所述频点所支持网络切片组合的优先级的正相关。
在一些实施例中，所述方法还包括：
接收优先级请求信息；
所述上报终端支持的网络切片的第二优先级信息，包括：
根据所述优先级请求信息，上报所述终端支持的网络切片的所述第二优先级信息。
第二优先级信息的上报，在一些情况下是终端主动上报的。在另一些情况下，第二优先级信息的上报是基站指示或请求的。例如，基站通过下发优先级请求信息指示终端上报第二优先级信息。
在一些实施例中，所述上报终端支持的网络切片的第二优先级信息，包括：
在所述终端支持的网络切片的优先级更新时，上报更新后的网络切片的所述第二优先级信息。
在终端支持的网络切片的优先级更新时才上报，这样可以减少比必要的上报。
在一些实施例中，所述方法还包括：
若所述终端支持的网络切片的优先级更新或第一定时器超时，上报第三指示；
所述接收优先级请求信息，包括：
接收基于所述第三指示下发的优先级请求信息。
例如，基站可以通过RRC消息或者MAC信令指示终端内配置第一定时器，然后终端根据第一定时器的定时，在超时时就上报第三指示。基站接收到该第三指示之后，就会根据自身通信状况或者需求，选择合适的时机下发所述优先级请求信息。
在一些实施例中，所述上报终端支持的网络切片的第二优先级信息，包括：
若第二定时器超时，上报所述终端支持的网络切片的所述第二优先级信息。
同样地，基站可以通过RRC消息或者MAC信令指示终端内配置第二定时器，然后终端根据第二定时器的定时，在超时时就主动上报所述第三指示。
在一些实施例中，所述第一定时器和第二定时器可以是不同的定时器，定时时长不同和/或定时的起始时间不同。
在另一些实施例中，所述第一定时器和第二定时器可以是同一个定时器，如此，基站仅需为UE配置一个定时器，且UE内也仅需维护一个定时器，简化定时工作。
在一些实施例中，所述上报终端支持的网络切片的第二优先级，包括：
当终端处于空闲态或非激活态，且所述终端支持的网络切片的优先级更新时，所述终端执行到连接态的切换；
在切换到连接态的过程中，上报更新后的网络切片的所述第二优先级。
在本申请实施例中，若终端处于空闲态或非激活态，监控到自身所支持的网络切片的优先级发生变化时，即终端自身所支持的网络切片的优先级更新时，会自动切换到连接态，如此可以及时上报自身更新后的 第二优先级信息，以方便网络侧对用于该终端的第一优先级信息的更新。
在一些实施例中，所述在切换到连接态的过程中，上报更新后的网络切片的第二优先级信息，包括：
在切换到连接态的过程中，使用连接建立请求消息上报更新后的网络切片的第二优先级信息；
或者，
在切换到连接态的过程中，使用连接建立完成消息上报更新后的网络切片的第二优先级信息；
或者，
在切换到连接态的过程中，使用连接恢复请求消息上报更新后的网络切片的第二优先级信息；
或者，
在切换到连接态的过程中，使用连接恢复完成消息上报更新后的网络切片的第二优先级信息。
总之，在本申请实施例中会使用切换到连接态过程中的连接消息来上报更新后的所述第二优先级信息，如此，不用引入新的消息信令来上报所述第二优先级信息，一方面与现有技术兼容性强，另一方面能够在终端切换到连接态之后就能够完成第二优先级信息的上报。
在另一些实施例中，所述第二优先级信息还可以是在终端附着过程中上报。

在终端的服务小区的频点和邻小区的频点支持的网络切片不同时，通过专门的第二指示告知终端，如此，终端在接收到第二指示时，就可认为自身当前驻留的服务小区与服务小区相邻的邻小区各自对应的频点所支持的网络切片不同。
在一些实施例中，所述610可包括：在终端进行TAU或RAU时，下发所述第一优先级信息。
如此，在TAU和RAU过程中下发所述第一优先级信息，而不用专门信令下发所述第一优先级信息，与相关技术兼容性大且节省了信令开销。

以下结合上述任一实施例提供一种信息处理方法，包括：
UE接收基站通过专用信令下发的频率和频率所支持的切片(Slice)组合的优先级信息，UE基于该组合优先级信息来确定小区的重选优先级，进行小区重选。
例如，
所述频率和网络切片组合的优先级由第一优先级信息指示。比如：以下是一种频率和频率所支持网络切片组合的优先级的比较示意。
f1+网络切片1+网络切片2>f2+网络切片1＝f1+网络切片1>f1+网络切片2＝f2+网络切片2。意思是支持网络切片1和网络切片2的f1频点其优先级高于只支持网络切片1的f2频点。只支持网络切片1的f2频点其优先级与只支持网络切片1的f1频点等等。一些频点如果不指示网络切片信息，比如指示f2>f1+网络切片1，代表对UE搜寻到的f2频率的小区，其优先级均高于f1+网络切片1下的小区。
在一些情况下，所述切片信息可以是S-NSSAI来标识，或者通过S-NSSAI里的切片类型字段SST(网络切片/Service type)来标识。
在一些情况下，对于同系统同频小区(intra-freq)和同系统异频小区(inter-freq)重选，对于具有相同freq+网络切片优先级的小区，UE对小区按信号质量排序后进行小区重选。此处的freq+网络切片优先级为频率及频率支持的网络切片组合的优先级。
在一些情况下，对于intra-freq、inter-freq和异系统(inter-RAT)小区重选，如果该freq+网络切片的优先级高于服务小区的freq+网络切片优先级，如果该freq+网络切片下存在小区其信号质量高于一定门限，UE重选到该freq+网络切片。
在一些情况下，对于intra-freq、inter-freq和inter-RAT小区重选，如果该freq+网络切片优先级低于服务小区的freq+网络切片优先级，如果服务小 区信号质量小于一定门限，且该freq+网络切片下存在小区其信号质量高于一定门限，UE重选到该freq+网络切片。
在一些情况下，UE接收基站广播的服务小区以及频点和/或频点的邻小区与支持的网络切片的对应关系表。UE通过该表确定服务小区以及频点和/或频点的邻小区所支持的网络切片。
对同系统同频小区(intra-frequency)，比如在SIB3的同系统同频小区列表(intraFreqNeighCellList)里指示邻小区(Neighbor cell)所支持的网络切片列表。
对同系统异频小区(inter-frequency)，比如在SIB4的同系统异频小区信息(InterFreqCarrierFreqInfo)里指示频点freq所支持的网络切片列表，或者在同系统异频小区载波频率信息(InterFreqCarrierFreqInfo)里的同系统异频小区信息(interFreqNeighCellInfo)里指示邻小区(Neighbor cell)所支持的网络切片列表。指示freq所支持的网络切片列表表示该freq下所有邻小区均支持该网络切片列表。
对异系统小区(inter-RAT)，比如在SIB5的载波频率信息(CarrierFreqEUTRA)里指示该freq所支持的网络切片列表，或者在CarrierFreqEUTRA里的邻小区频点信息(EUTRA-FreqNeighCellInfo)o里指示Neighbor cell所支持的网络切片列表。
在一些情况下，如果服务小区的信号质量大于一定门限，且系统消息里指示的intra-freq邻小区及其对应网络切片中没有比服务小区及其支持的网络切片优先级高的邻小区，UE可以不执行intra-freq测量；否则，UE需要执行intra-freq测量。
在一些情况下，如果服务小区的信号质量大于一定门限，对于系统消息里指示的inter-freq或inter-RAT频点和支持的网络切片中，如果不存在其它频点及其支持的网络切片其优先级高于服务小区对应频点+网络切片的 优先级，UE可以对该频点不执行inter-freq或inter-RAT的信号测量。
在另一种实施方式中，UE接收基站广播的是否支持广播网络切片的指示，UE通过该指示来确定基站是否支持广播服务小区以及频点和/或频点的邻小区支持的网络切片。
在一些情况下，如果基站广播指示支持广播网络切片，如果系统消息里指示的服务小区没有指示支持的网络切片，或系统消息里指示的频点(如果该频点里未指示邻小区)没有指示支持的网络切片，或系统消息里指示的频点的邻小区和频点均没有指示支持的网络切片，则认为该频点或邻小区与服务小区支持相同的网络切片。
在一些情况下，如果基站广播指示不支持广播网络切片，UE则不能通过系统消息确定频点和邻小区的网络切片。
在一些情况下，UE在TAU/RAU时，网络发送更新的频率和频率所支持的切片(网络切片)组合的优先级信息。
所述更新可以通过RRC释放(release)消息发送，可包括：
UE接收基站广播的是否存在邻小区其网络切片与服务小区网络切片不同的指示。如果指示不存在，UE认为所有邻小区均与服务小区网络切片相同。如果指示存在，如果系统消息里指示的频点(如果该频点里未指示邻小区)没有指示对应的网络切片，或系统消息里指示的频点的邻小区和/或频点没有指示对应的网络切片，则认为该频点或邻小区与服务小区有相同的网络切片。
在一些情况下，如果基站不广播是否存在邻小区其网络切片与服务小区网络切片不同的指示，UE则不能通过系统消息确定频点和邻小区的网络切片。
在一些情况下，UE向基站指示各网络切片或及其网络切片组合的优先级信息。
比如UE支持网络切片A，B，C，UE可以指示网络切片A+B>网络切片A>网络切片B。网络可以根据该优先级信息来给UE配置频率+网络切片组合的优先级。
UE可以基于网络切片A，B，C发生的频率来决定网络切片的优先级，比如业务发生频率网络切片A>网络切片B>网络切片C，那么网络切片A+B>网络切片A>网络切片B>网络切片C。
支持高优先级的网络切片或网络切片组合的频率优先级高于支持低优先级的网络切片或网络切片组合的频率。
在一些情况下，UE向基站指示各网络切片或及其网络切片组合的优先级信息前，接收基站发送给UE的网络切片优先级请求信息。
在一些情况下，基站在发送给UE的网络切片优先级请求信息前，可以先接收UE指示的是否有网络切片优先级信息的指示。
UE可以在需要更新网络切片优先级信息时发送该指示。
在一些情况下，基站可以配置一个定时器来限定UE发送8或10所述的消息的频率。也即每发送一次所述消息，启动定时器，在定时器超时前不能再次发送所述消息。
在一些情况下，处于空闲态(idle)态或非激活(inactive)态下UE，在网络切片优先级信息变更后，可以发起连接建立或恢复流程，以便指示有网络切片优先级信息指示。从而让网络获取更新的优先级信息。
可以通过连接建立请求/完成消息，连接恢复请求或完成消息来携带该指示。
