技术领域
本公开涉及通信技术领域，特别涉及一种异频信息的指示方法和接入网节点。
背景技术
新空口(New radio，NR)系统中引入了网络切片的概念，不同的切片类型对应着不同的业务类型，运营商可以根据自身的需求在网络侧灵活配置其所支持的网络切片类型，为了最大限度提高网络侧切片部署的灵活性，不同频点小区部署的切片类型支持独立配置。目前，同频小区之间的小区重选不需要考虑网络切片的限制，在网络部署切片的背景下，进行异频小区重选或者切换的终端最好能够重选或者切换到支持其业务的异频小区上，否则终端存在频繁进行异频小区重选或切换的可能性，在极端条件下，甚至存在连接态终端服务中断的可能性。因此，终端如果能够从网络侧获知异频邻区的切片类型支持信息，就能重选或切换到适合该终端的异频小区上，从而最大限度优化终端进行异频小区重选或者切换的过程。从核心网来看，切片类型在将来仍然存在增加的可能性，一旦核心网切片支持类型发生改变(含增加或者删减)，网络侧广播的异频小区切片支持信息也需要更新，从网络侧来讲，运营商可以为核心网提供多种切片划分服务优先级，考虑网络侧负载均衡策略，切片服务优先级信息应该支持半静态配置。
但是相关技术中的长期演进(Long Term Evolution，LTE)系统进行异频小区重选或切换时没有切片类型的概念，如果在NR系统中沿用LTE异频小区重选或切换机制会造成终端小区重选或切换的盲目性，一旦终端重选或切换选择的小区不支持终端需求的切片业务将导致终端进行新的重选或切换过 程，这样看来，沿用LTE异频小区重选或切换机制不仅增加了终端的功耗，同时也难以保证终端服务的连续性。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图及具体实施例对本公开进行详细描述。
下面首先对LTE中异频小区重选和切换进行简要说明如下。
一、LTE异频小区重选
机制：异频小区重选包含异频重选测量和异频重选执行准则判断两部分
过程1：异频小区重选测量
对于比当前进化型的统一陆地无线接入网络(Evolved Universal Terrestrial Radio Access Network，E-UTRAN)频点优先级高的E-UTRAN频点或者异系统频点，总是执行异频小区重选测量；
对于等于或者低于当前E-UTRAN频点优先级的E-UTRAN频点或者低于当前E-UTRAN频点优先级的异系统频点，如果服务小区同时满足Srxlev>SnonIntraSearchP和Squal>SnonIntraSearchQ，则不进行等于或者低于当前E-UTRAN频点优先级的E-UTRAN频点或者异系统频点测量，除非用户设备(User Equipment，UE，也称终端)被重定向信息触发进行E-UTRAN异频测量；如果不能同时满足Srxlev>SnonIntraSearchP和Squal>SnonIntraSearchQ条件，则终端需要执行等于或者低于当前E-UTRAN频点优先级的E-UTRAN频点或者异系统频点测量。
过程2：异频重选执行准则判断
对于比当前E-UTRAN频点优先级高的E-UTRAN频点或者异系统频点，当满足以下准则时执行异频重选：
A1、在时间TreselectionRAT内，优先级高的E-UTRAN频点或者异系统频点小区一直满足Srxlev>ThreshX,HighP；
A2、终端在当前小区驻留超过1秒。
对于同等优先级的异频小区按照R准则进行小区排序选择最好的小区进行异频切换。
对于比当前E-UTRAN频点优先级低的E-UTRAN频点或者异系统频点，当满足以下准则时执行异频重选：
B1、在时间TreselectionRAT内，服务小区Srxlev<ThreshServing,LowP且优先级低的E-UTRAN频点或者异系统频点小区一直满足Srxlev>ThreshX, LowP；
B2、终端在当前小区驻留超过1秒。
二、LTE异频小区切换
终端根据服务小区的测量配置测量周围异频小区质量并按照一定规则上报给服务小区，收到终端测量报告的服务小区根据报告中的异频邻区链路质量等信息判断合适的异频切换小区并向目标小区发起切换请求，一旦目标小区通过切换请求并告知服务小区，服务小区随即告诉终端进行异频小区切换。
LTE系统信息块(System Information Block，SIB)中广播的异频信息
LTE SIB5中广播了异频小区列表及频点优先级信息。空闲态终端可以从服务小区广播中读取这些异频小区列表及频点优先级信息，从而根据上述LTE异频小区重选步骤完成异频小区重选过程。
本公开针对因终端侧不知道异频邻区的切片支持情况，影响后续的终端重选或切换的过程，无法保证网络通信可靠性的问题，提供一种异频信息的指示方法、接入网节点及核心网节点。
如图1所示，本公开实施例的异频信息的指示方法，应用于第一小区所在的第一接入网节点，包括：
步骤11，接收第二接入网节点发送的第二小区的切片相关的配置信息；
其中，所述第二小区为所述第一小区的异频邻区。
需要说明的是，本实施例中所说的第一小区为终端的服务小区或驻留小区；而第二小区为第一小区的异频邻区，通常情况下，该第一小区和第二小区属于不同接入网节点下的小区；且本实施例中说指的接入网节点可以是全球移动通讯(Global System of Mobile communication，简称GSM)或码分多址(Code Division Multiple Access，简称CDMA)中的基站(Base Transceiver Station，简称BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，简称WCDMA)中的基站(NodeB，简称NB)，还可以是LTE中的演进型基站(Evolutional Node B，简称eNB或eNodeB)，或者中继站或接入点，或者未来5G网络中的基站等，在此并不限定。
具体地，在所述接收第二接入网节点发送的第二小区的切片相关的配置信息的步骤之后，还包括：
存储所述配置信息；
所述配置信息包括：第二小区支持的频点以及与所述频点对应的切片信息和频点优先级信息；或者
所述配置信息包括：第二小区支持的频点以及与所述频点对应的切片信息、频点优先级信息和切片映射规则；
其中，所述第二小区支持的频点以及与所述频点对应的切片信息隐性或显性指示切片优先级信息。
需要说明的是，该第二小区可能包含多个支持的频点，且每个频点可能又会对应着有多个切片，因此为了明确告诉终端具体有哪些频点以及切片，该配置信息中应该包含第二小区支持的频点以及该频点对应的切片，因为第二小区支持的频点可能是多个，所以为了指示不同的频点的优先级，该配置信息中也得需要包含频点优先级信息；需要说明的是，虽然某些切片不在本地小区直接支持的切片当中，但是运营商或者核心网可以规定哪些本地小区不直接支持的切片可以向哪些本地支持的切片进行映射，在存在上述情况时，该配置信息中应当包含切片映射规则。还需要说明的是，第二小区支持的频点以及与所述频点对应的切片信息通常以切片列表的形式存在，该切片列表可以隐性或显性指示切片优先级信息；其中，隐性指示指的是切片列表中的切片以优先级顺序进行排序，例如，按照切片优先级进行降序排列或升序排序；显性指示指的是每个切片都对应有明确的优先级标识，表明该切片的优先级。
进一步地，步骤11的具体实现方式为：在确定第一接入网节点和第二接入网节点之间可以进行配置信息交互时，接收第二接入网节点发送的第二小区的切片相关的配置信息；
其中，所述配置信息由所述第二接入网节点主动发送；或者
所述配置信息由所述第二接入网节点基于所述第一接入网节点的请求发送。
需要说明的是，该配置信息可以是第二接入网节点主动发送给第一接入网节点的，即当第二接入网节点获取到核心网侧的相关配置时，主动将配置信息发送给第一接入网节点；该配置信息也可以是由第一接入网节点请求发 送的，即第一接入网节点先发送请求消息，然后第二接入网节点根据该请求消息，反馈配置信息给第一接入节点。
具体地，第二接入网节点获取配置信息的方式为：首先接收核心网节点在预设时间窗口内主动发送的网络支持的切片信息；或者接收核心网节点基于第二接入网节点的切片信息获取请求，在预设时间窗口内发送的网络支持的切片信息；然后根据所述切片信息，获取第二小区所支持的切片相关的配置信息；最后第二接入网节点将所述配置信息发送给第一小区所在的第一接入网节点；通常情况下，该第二接入网节点在获取到配置信息后也需要将配置信息进行存储。
下面在实际应用中，对第二接入网节点和第一接入网节点的配置信息中的第二小区(即切片源小区，本文中将提供异频邻区支持的切片信息的小区称为切片源小区，而将接收并保存异频邻区支持的切片信息的小区称为切片合作小区，上文所说的第一小区即切片合作小区)支持的频点以及与所述频点对应的切片信息的初始化过程进行说明，首先需要说明的是，切片源小区会根据与其相连的一个或多个核心网提供的网络切片信息及运营商自身切片业务优先级策略在本地小区固定存储单元中生成一个自身所支持的切片列表；接着，切片源小区所在接入网节点通过Xn接口(即两个接入网节点之间通信所用的接口)发送切片列表拷贝发送请求(Slice List Copy Forward Request)消息将这一本地业务支持的切片列表拷贝给相邻的每一个异频小区并在异频小区各自专用存储单元中完整存储。需要指出的是，网络侧的切片业务优先级划分原则是由运营商决定的网络侧策略实现。
如图2所示，第二接入网节点的第二小区支持的频点以及与所述频点对应的切片信息(以下称为切片列表)的初始化过程具体为：
步骤A1、第二接入网节点发送切片信息获取请求给核心网节点；
步骤A2、核心网节点反馈切片信息获取请求响应给第二接入网节点；
步骤A3、核心网节点发送切片信息给第二接入网节点；
步骤A4、第二接入网节点发送切片信息发送完成确认信息给核心网节点。
第二接入网节点通过与其连接的核心网节点通知的切片信息设置切片源小区支持的切片类型的切片列表。
如图3所示，当第二接入网节点主动发送切片列表时，第二接入网节点和第一接入网节点之间的交互流程为：
步骤B1、第二接入网节点发送列表拷贝发送请求给第一接入网节点；
需要说明的是，在此种情况下，第二接入网节点已经根据核心网通知的切片信息设置了切片源小区所支持的切片列表，且该列表拷贝发送请求中包含小区ID信息，还需要说明的是，如果第二小区的异频邻区有多个，第二接入网节点可以分别发送列表拷贝发送请求给不同的第一接入网节点。
步骤B2、第一接入网节点反馈列表拷贝发送请求响应给第二接入网节点；
需要说明的是，该列表拷贝发送请求响应中携带有第一接入网节点的切片源小区的ID信息。
步骤B3、第二接入网节点向第一接入网节点发送切片列表；
需要说明的是，此处第二接入网节点在进行切片列表的发送时，还需要携带第二小区的ID信息，同时，还将频点优先级信息和可能的切片映射规则发送给第一接入网节点。
步骤B4、第一接入网节点反馈切片列表发送完成的确认信息给第二接入网节点；
需要说明的是，在确认信息发送时，还应携带切片合作小区的ID信息。
还需要说明的是，步骤B1和步骤B3的消息中均不含任何切片源小区提供的运营商切片优先级策略指示信息，切片源小区提供的原始切片列表拷贝已经隐式包含了运营商切片优先级策略。由于该切片列表在切片源小区和切片合作小区之间都存有相同的完整版本，因而该切片列表支持索引查找功能，该过程可能含有切片映射规则，该规则既可以是核心网指示给网络侧(即第二接入网节点)的，也可以是网络侧自己制定的规则。
需要说明的是，当第一接入网节点在接收到该配置信息后，便可以根据该配置信息得到系统广播消息，具体地，根据所述配置信息生成系统广播消息中的第二预设域，所述第二预设域存在于最小系统广播消息中或除了最小系统广播消息的其它广播消息中。
需要说明的是，该第二预设域为第一接入网节点进行该配置信息发送所单独分配的传输资源；该第二预设域可以在最小系统广播消息中由第一接入 网节点主动广播给终端，也可以根据终端的主动请求，在除了最小系统广播消息的其它广播消息广播给终端。
需要说明的是，第一接入网节点在接收到该配置信息后，为了便于后续的使用，还需要存储所述配置信息。
随着网络的运行以及运营商策略的变化，上述的配置信息也会发生变化，因此，本公开实施例的频信息的指示方法，在步骤11之后，还包括：
接收第二接入网节点发送的配置信息的更新指示；
根据所述更新指示，对所述配置信息进行更新；
根据更新的配置信息生成系统广播消息中的第一预设域，所述第一预设域存在于最小系统广播消息中或除了最小系统广播消息的其它广播消息中；
其中，所述更新指示包括：第二小区支持的频点以及与所述频点对应的切片信息的第一更新信息、频点优先级信息的第二更新信息和切片映射规则的第三更新信息中的至少一项。
需要说明的是，在所述更新指示包括：第二小区支持的频点以及与所述频点对应的切片信息的第一更新信息时，所述第一更新信息中包含用于指示增加切片和/或删减切片的指示信息，且为了减少信息传输中资源的开销，所述指示信息中携带有切片的标识信息(因切片信息通常以切片列表的形式存在，且该切片列表支持角标索引的功能，即每个切片用一个对应的索引便能表示，此处的切片的标识信息便是用来区分不同切片的索引)，所述标识信息用于指示增加和/或删减的切片。
需要说明的是，对于切片的更新不仅包括切片的增加和/或删减，还应包括频点中切片优先级的更新，所以在所述更新指示包括：第二小区支持的频点以及与所述频点对应的切片信息的第一更新信息时，所述第一更新信息中还包含更新预设频点中切片优先级的指示信息。该指示信息用于指示切片优先级的变更，具体地，可以是具体地切片变更后的优先级等级，也可以是切片优先级变更后的全部切片优先级的信息。
还需要说明的是，在所述更新指示包括：频点优先级信息的第二更新信息和/或切片映射规则的第三更新信息时，所述第二更新信息和/或第三更新信息根据运营商策略的变化和网络负载的变化中的至少一项获取得到；即运营 商策略的变化和/或网络负载会导致频点优先级信息的更新，而运营商策略的变化和/或网络负载的变化也会导致切片映射规则的更新。
因配置信息的更新可以是第二小区支持的频点以及与所述频点对应的切片信息的更新、也可以是频点优先级信息的更新，还可以是切片映射规则的更新，下面分别从不同的更新触发方式，对更新流程进行具体说明如下。
一、如果核心网侧的网络切片类型发生了增加或者删减，核心网节点需要通知与其相连的每一个接入网节点进行接入网侧网络切片类型更新操作，接入网节点本地存储的切片列表更新完后需要通知每一个异频邻区进行切片列表的更新。
如图4所示，切片源小区的切片列表更新过程具体为：
步骤C1、核心网节点发送切片类型更新通知请求给第二接入网节点；
步骤C2、第二接入网节点发送切片类型更新通知请求响应给核心网节点；
步骤C3、核心网节点将切片类型更新通知发送给第二接入网节点；
步骤C4、第二接入网节点反馈切片类型更新通知发送完成的确认消息给核心网节点。
此后，第二接入网节点通过与其连接的核心网节点通知的切片类型更新信息，更新切片源小区支持的切片列表。
如图5所示，切片合作小区的切片列表更新过程具体为：
步骤D1、第二接入网节点发送切片类型更新通知请求给第一接入网节点；
步骤D2、第一接入网节点反馈切片类型更新通知请求响应给第二接入网节点；
步骤D3、第二接入网节点向第一接入网节点发送切片类型更新通知；
步骤D4、切片类型更新通知发送完成，第一接入网节点向第二接入网节点反馈确认消息。
然后第一接入节点根据第二接入网发送的更新通知本地切片列表(即切片合作小区的切片列表)。
这里需要说明的是，在步骤D1发送的消息中，包含一个比特信息用于指示该消息是切片添加操作还是切片删除操作。
二、在LTE系统中，频点优先级是一个与运营商频点布局策略及小区负 载均衡相关联的参数，LTE系统中异频频点优先级在SIB5中广播。在NR切片技术背景下，我们仍然希望保留LTE异频频点优先级反映该频点负载情况的特性，同时使用运营商制定的半静态切片优先级策略来辅助服务小区为终端进行异频小区重选或者异频小区切换过程。网络初始化在切片源小区生成的切片业务支持列表是静态存储在切片源小区和切片合作小区当中的，而核心网侧网络切片改变发起的切片源小区列表更新及切片合作小区列表更新过程会同时改变切片源小区和切片合作小区当中存储的静态切片业务支持列表；由切片源小区运营商切片优先级策略改变或者切片源小区频点优先级改变而发起的异频切片合作小区列表更新过程是一个临时可变策略，该临时改变策略只是用来动态指示本小区在其他系统信息(other SI)中广播的异频小区切片业务支持列表信息从而优化终端基于切片业务的异频小区重选或者异频小区切换过程，并没有改变初始化生成或者由切片源小区运营商切片优先级策略改变或者切片源小区频点优先级改变而发起的异频切片合作小区列表更新生成的本地静态切片列表。
如图6所示，切片合作小区其他系统信息动态改变的具体流程为：
步骤E1、第二接入网节点发送广播策略改变通知请求给第一接入网节点；
步骤E2、第一接入网节点反馈广播策略改变通知请求响应给第二接入网节点；
步骤E3、第二接入网节点发送广播策略改变通知给第一接入网节点；
步骤E4、在广播策略更改通知接收完成后，反馈确认消息给第二接入网节点。
第二接入网节点基于广播策略更改通知更新异频广播中的信息。
需要说明的是，步骤E3中的策略改变信息包含三个方面，一是更新的频点优先级值，该值反映的是异频资源使用状况，主要用于反映该异频整体资源负载信息；二是由运营商制定的用于临时改变切片合作小区其他系统信息(other SI)中广播的异频切片业务支持列表的切片临时优先级指示信息，该优先级信息与静态切片业务支持列表中的隐含切片优先级不同并且只是临时起作用，由于切片合作小区中的静态切片业务支持列表与源切片小区完全一致，步骤E3中的切片临时优先级指示信息可支持角标索引指示，再加上切片 源小区采用事件触发周期性上报的策略与切片合作小区进行切片临时优先级指示信息交互，因而Xn接口的开销也不会很大，三是该过程可能含有异频邻区切片映射规则，该规则既可以是核心网指示给网络侧的，也可以是网络侧自己制定的规则。需要指出的是切片源小区在步骤E3中指示的切片临时优先级信息是运营商切片相关的策略，比如运营商给每一个切片源小区支持的切片业务划分一个资源使用额度，如果某一支持切片使用的资源额度大于某一阈值就将该切片业务优先级降为最低并给切片合作小区发出临时优先级指示信息，从而让切片合作小区在其other SI的异频切片业务支持列表区域不广播该切片业务，从而避免终端进行不合适的异频小区重选或者异频小区切换过程。
如图7所示，当第一接入网节点基于广播策略更改通知更新异频广播中的信息后，终端通过其他广播消息获取异频广播信息的具体实现过程为：
步骤F1、终端发送随机接入前导码给第一接入网节点；
步骤F2、第一接入网节点反馈随机接入响应给终端；
步骤F3、终端发送其他系统信息请求指示符给第一接入网节点；
步骤F4、第一接入网节点进行其他系统信息的广播；
终端在接收到广播的其他系统信息后，根据该系统信息进行异频小区的重选。
从终端的角度来看，该异频切片广播优化策略适用于空闲态、非激活态或者连接态，其中空闲态终端可以结合服务小区Other SI中广播的异频小区切片支持信息及自身切片业务需求做出更加优化的异频小区重选执行判断；终端在非激活态或者连接态可以通过专用信令获取服务小区Other SI中的异频小区切片支持信息，非激活态终端可以更加精准的完成异频小区重选、RNA过程及连接恢复过程，而连接态终端也可以精准完成异频小区切换过程。
本公开实施例，通过获取异频邻区的切片相关的配置信息，使得终端在后续的小区重选或切换的过程可以依据该配置信息进行，此种方式，保证了网络通信的可靠性，减少了终端的功耗。
