Description

关系指示、信息传输方法和装置、通信装置和存储介质 技术领域
本公开涉及通信技术领域，具体而言，涉及关系指示方法、信息传输方法、关系指示装置、信息传输装置、通信装置和计算机可读存储介质。
背景技术
网络切片(简称切片slice)可以为特定用户提供一个完整的端到端虚拟网络。通过将网络资源划分为多个网络切片，5G网络切片可以为具有不同服务需求(例如：延迟、可靠性、容量、隔离以及其他功能)的用户提供差异化服务。据此，运营商网络不但可以服务于以“尽力而为(Best Effort)传输”为通信需求特征的信息消费类业务，也可以满足以“确定性传输”为通信需求的生产控制类服务，为通信需求迥异的服务分配逻辑上或者物理上隔离的网络资源。
在切片的基础上，进一步还提出了切片分组(slice group)，一个或多个切片可以映射到一个切片分组。目前的切片分组是针对跟踪区域(Tracking Area，TA)分别配置的，不同TA中切片分组与切片之间的映射关系可以有所不同，当终端处于相邻TA的边缘进行某些操作时，会存在一些问题。

具体实施方式
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做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
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”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”可以被解释成为“在……时”或“当……时”或“响应于确定”。
出于简洁和便于理解的目的，本文在表征大小关系时，所使用的术语为“大于”或“小于”、“高于”或“低于”。但对于本领域技术人员来说，可以理解：术语“大于”也涵盖了“大于等于”的含义，“小于”也涵盖了“小于等于”的含义；术语“高于”涵盖了“高于等于”的含义，“低于”也涵盖了“低于等于”的含义。
图1是根据本公开的实施例示出的一种关系指示方法的示意流程图。本实施例所示的关系指示方法可以由终端执行，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述终端可以与网络侧设备通信，所述网络侧设备包括但不限于4G、5G、6G等通信系统中的网络侧设备，例如基站、核心网等。
如图1所示，所述关系指示方法可以包括以下步骤：
在步骤S101中，通过接入AS层(Access Stratum)接收非接入层NAS(Non-Access Stratum)指示，以确定所述终端所在区域和/或所述区域的邻区域对应的切片分组与切片之间的映射关系。
在一个实施例中，切片分组是针对每个区域分别配置的，所述区域包括但不限于跟踪区域TA、小区cell。以下实施例主要在所述区域为TA的情况下进行示例性说明。
切片分组可以针对每个TA分别配置，也即切片分组slice group是per TA的配置，在这种情况下，切片分组与切片之间的映射关系也是针对每个TA分别配置的，因此，不同的TA可以对应不同的映射关系。在这种情况下，当终端处于相邻TA之间进行某些操作(包括但不限于小区重选、随机接入)时，会存在一些问题。
以相邻的两个跟踪区域TA1和TA2为例，在TA1对应的映射关系1中，切片1映射到切片分组1，而在TA2对应的映射关系2中，切片1映射到切片分组2。
当终端处于TA1和TA2之间的边界进行小区重选时，终端可以确定期望使用的切片，例如切片1，进而确定支持切片1的小区进行小区重选。
网络侧设备可以通过广播、单播等方式向终端指示切片信息对应的频率优先级、小区支持的切片信息等。以网络侧设备向终端指示小区支持的切片信息为例，若指示的是小区支持的切片分组，终端在选择小区(例如合适的小区suitable cell或者其他小区)后，例如确定的选择的小区为小区1，为了根据网络侧设备指示的小区支持的切片分组确定小区1是否支持切片1，就需要先确定切片1对应的切片分组。
TA对应的映射关系存储在NAS层中，而进行小区重选的相关操作则由AS层进行的，为了确定切片1对应的切片分组，终端中的AS层可以将切片1的标识，例如S-NSSAI(Single-Network Slice Selection Assistance Information，单一网络切片选择辅助信息)发送至NAS层，NAS层根据映射关系确定切片1对应切片分组，例如确定切片1对应的切片分组的标识slice group ID，并将切片分组的标识发送至AS层。在此过程中，NAS层中保存的TA对应的映射关系对于AS层是透明的，也即AS层并不知道TA对应的映射关系，只能接收到NAS层发送的slice group ID，并通过其来确定切片1对应的切片分组。
在此过程中存在的问题是，若终端位于TA1内，但是小区1位于TA2内，由 于NAS层并不知道终端需要确定小区1是否支持切片1，那么在确定切片1对应的切片分组时，可能会根据TA1对应的映射关系1确定切片1对应的切片分组。但是由于小区1位于TA2内，应该根据TA2对应的映射关系2确定切片1对应的切片分组，而TA2对应的映射关系2与TA1对应的映射关系1不一定相同。因此根据TA1对应的映射关系1确定切片1对应的切片分组可能会导致确定的切片分组出现错误，进而导致不能准确确定小区1对于切片1的支持情况。
根据本公开的实施例，终端中的NAS层可以将终端所在区域和/或所述区域的邻区域对应的切片分组与切片之间的映射关系发送至AS层，使得AS层在需要根据切片对应的切片分组进行操作时，能够根据所述切片分组与切片之间的映射关系准确地确定切片对应的切片分组。
仍以上述场景为例，根据本公开的实施例，例如NAS层将终端所在TA1对应的切片分组与切片之间的映射关系1，以及与TA1相邻的TA2对应的切片分组与切片之间的映射关系2发送至AS层，由于AS层在确定切片1对应的切片分组时，知道需要确定小区1是否支持切片1，并且可以确定小区1是位于TA2之内，因此可以根据TA2对应的映射关系2确定切片1对应的切片分组，从而准确地确定切片1对应的切片分组，进而根据网络侧指示的小区(非特定的一个或多个小区)支持的切片分组，准确地确定小区1对于切片1的支持情况。
在一个实施例中，所述通过接入AS层接收非接入NAS层指示包括：
通过所述AS层接收所述NAS层发送的切片相关信息，其中，所述切片相关信息包括以下至少之一：
切片；
切片优先级；
所述映射关系；
所述映射关系的有效作用区域与所述映射关系之间的对应关系。
在一个实施例中，NAS层可以向AS层发送切片相关信息，而切片分组与切片之间的映射关系可以包含在切片相关信息中。
在切片相关信息中，除了可以包括所述映射关系，还可以包括所述映射关系的有效作用区域与所述映射关系之间的对应关系，例如一个映射关系可以对应的有效作 用区域可以是一个或多个，对应关系的形式包括但不限于列表list，例如映射关系1对应的有效作用区域为TA1，映射关系2对应的有效作用区域为TA2。需要说明的是，所述有效作用区域包括但不限于小区cell、跟踪区域TA。
进一步地，切片相关信息还可以包括切片，例如终端期望使用的切片，例如终端在需要进行某些业务时，可以期望使用该业务对应的切片；切片相关信息还可以包括切片(例如期望使用的切片)的切片优先级，例如终端期望使用的切片包括多个切片，可以根据切片优先级确定这多个切片之间的优先级关系，后续在进行切片相关操作时，例如基于切片进行小区重选时，可由根据切片优先级逐个考虑切片。
在一个实施例中，所述方法还包括：根据所述切片相关信息进行小区重选。终端可以根据切片相关信息进行小区重选，例如在小区重选过程中，可以根据切片相关信息中的映射关系确定切片对应的切片分组。
图2是根据本公开的实施例示出的另一种关系指示方法的示意流程图。如图2所示，所述方法还包括：
在步骤S201中，根据网络侧设备发送的第一指示信息确定切片和/或切片分组对应的频率优先级。
在一个实施例中，网络侧设备可以通过第一指示信息向终端指示切片对应的频率优先级和/或指示切片分组对应的频率优先级，其中，频率优先级可以供终端进行小区重选，例如终端在进行小区重选时，可以按照频率优先级由高到低逐个考虑频率。
其中，频率优先级对应的切片和/或切片分组，包括终端当前服务频点支持的切片和/或切片分组，也可以包括当前服务频点的邻频支持的切片和/或切片分组。
在一个实施例中，所述第一指示信息携带在以下至少之一中：
系统信息块SIB(System Information Block)：
无线资源控制释放RRC(Radio Resource Control)Release消息。
在一个实施例中，SIB携带的切片信息相关的信息，可以包括切片分组相关的信息；RRCRelease消息携带的切片信息相关的信息，可以包括切片分组相关的信息(例如指示的为与切片分组的标识相关的信息)，也可以包括单个切片相关的信息(例如指示的为与单个切片的标识S-NSSAI相关的信息，以下将单个切片相关描述为切片相关)。
其中，切片信息相关的信息，包括但不限于切片信息对应的频率优先级、小区支持的切片信息。
例如在切片信息相关的信息包括切片信息对应的频率优先级时，SIB中携带的第一指示信息可以指示切片分组对应的频率优先级；RRCRelease消息携带的第一指示信息可以指示切片分组对应的频率优先级，和/或指示切片对应的频率优先级。
例如在切片信息相关的信息包括小区支持的切片信息时，SIB中携带的第二指示信息可以指示小区支持的切片分组；RRCRelease消息携带的第二指示信息可以指示小区支持的切片分组，和/或指示小区支持的切片。
以下实施例先针对第一指示信息进行示例性说明，后对第二指示信息进行示例性说明。
在一个实施例中，在所述第一指示信息携带在SIB中时，所述第一指示信息用于指示切片分组对应的频率优先级；
在所述第一指示信息携带在RRCRelease消息中时，所述第一指示信息用于指示切片对应的频率优先级和/或指示切片分组对应的频率优先级。
由于SIB一般为网络侧设备广播的消息，可能不一定被特定的终端接收到，使得在一定程度上会存在安全问题，因此在第一指示信息携带在SIB中时，可以不指示具体切片对应的频率优先级，而是指示切片分组对应的频率优先级。
而RRCRelease则是单播消息，只会被特定的终端接收到，所以一般并不会存在类似SIB消息的安全问题，因此在第一指示信息携带在RRCRelease中时，可以指示具体切片对应的频率优先级，也可以指示切片分组对应的频率优先级，具体可以根据需要设置。
图3是根据本公开的实施例示出的又一种关系指示方法的示意流程图。如图3所示，所述根据所述切片相关信息进行小区重选包括：
在步骤S301中，按照所述切片优先级由高到低逐个选择切片；
在步骤S302中，确定选中的切片对应的频率优先级。
在一个实施例中，终端在根据切片相关信息进行小区重选时，可以根据切片优先级由高到低逐个选择切片，然后确定选中的切片对应的频率优先级。
在一个实施例中，所述方法还包括：
按照频率优先级由高到低选择频率，确定选中的频率对应的所有小区的排名；
根据排名选择小区，判断选中的小区是否支持选中的切片；
响应于至少满足所述选中的小区支持所述选中的切片，重选到所述选中的小区；
响应于所述选中的小区不支持所述选中的切片，选择下一个排名的小区，直至确定到选中的小区支持所述选中的切片为止，或者遍历选中的频点对应的所有小区则选择下一个优先级的频率。
在一个实施例中，在确定频率优先级后，可以进行小区重选，而在进行小区重选之前，需要先确定小区对于选中的切片的支持情况。
首先可以按照频率优先级由高到低选择频率，确定选中的频率对应的所有小区的排名，例如根据R准则确定排名。进而根据排名选择小区，并判断选中的小区是否支持选中的切片。
响应于至少满足所述选中的小区支持所述选中的切片，重选到所述选中的小区，也即重选到选中的小区的条件，至少包括选中的小区支持所述选中的切片，还可以包括选中的小区满足合适的小区suitable cell的判定条件；
响应于所述选中的小区不支持所述选中的切片，选择下一个排名的小区，直至确定到选中的小区支持所述选中的切片，或者遍历选中的频点对应的所有小区则选择下一个优先级的频率，并执行本实施例中的上述步骤。
在一个实施例中，所述方法还包括：
按照频率优先级由高到低选择频率，确定选中的频率对应的所有小区的排名；
根据排名选择排名最高的小区，确定选中的小区是否支持选中的切片；
响应于至少满足所述排名最高的小区支持所述选中的切片，重选到所述排名最高的小区；
响应于所述排名最高的小区不支持所述选中的切片，选择下一个优先级的频率。
在一个实施例中，在确定频率优先级后，可以进行小区重选，而在进行小区重选之前，需要先确定小区对于选中的切片的支持情况。
首先可以按照频率优先级由高到低选择频率，确定选中的频率对应的所有小区的排名，例如根据R准则确定排名。根据排名选择排名最高的小区，并确定选中的小区是否支持选中的切片。
响应于至少满足所述选中的小区(也即排名最高的小区)支持所述选中的切片，重选到所述选中的小区，也即重选到选中的小区的条件，至少包括选中的小区支持所述选中的切片，还可以包括选中的小区满足合适的小区suitable cell的判定条件；
响应于所述选中的小区不支持所述选中的切片，可以选择下一个优先级的频率，并执行本实施例中的上述步骤。
在一个实施例中，重选过程主要可以包括以下步骤：
步骤A：根据切片优先级由高到低选择切片，确定选中的切片对应的频率优先级；
步骤B：根据确定的频率优先级由高到低选择频率，确定选中的频率对应的所有小区的排名(例如根据R准则确定排名)；例如选中的切片对应的频率优先级为频率f1高于频率f2，那么可以先针对f1执行步骤B和步骤C，若未确定到支持选中的切片的小区，再针对f2执行步骤B和步骤C；
步骤C：根据排名选择小区，判断选中的小区是否支持选中的切片；
若选中的小区不支持选中的切片，可以执行步骤D：选中下一个优先级的小区判断是否支持选中的切片，直至确定到支持选中的切片的小区或遍历排名对应的所有小区为止，执行步骤B、步骤C和步骤D，并循环，直至确定到支持选中的切片的小区或遍历选中的切片对应的所有频率为止；
或者，在选中排名最高的小区时，若选中的小区不支持选中的切片，可以执行步骤B和步骤C，并循环，直至确定到支持选中的切片的小区或遍历选中的切片对应的所有频率为止；
在遍历选中的切片对应的频率优先级对应的所有频率优先级后，若仍未确定到支持选中的切片的小区，可以执行步骤A即后续步骤(例如步骤B和步骤C，或者步骤B、步骤C和步骤D)，并循环，直至确定到支持选中的切片的小区或遍历切片优先级对应的所有切片。
在遍历切片优先级对应的所有切片后，若仍未确定到支持选中的切片的小区， 那么可以按照传统legacy方式进行小区重选，例如根据网络侧指示的legacy频率优先级(而不是切片信息对应的频率优先级)进行小区重选。
由于第一指示信息既可以携带在SIB中，也可以携带在RRCRelease消息中，并且SIB中携带的第一指示信息和RRCRelease消息携带的第一指示信息可以相同，也可以不同。因此，在第一指示信息既可以携带在SIB中又携带在RRCRelease消息中时，就需要考虑SIB中第一指示信息和RRCRelease消息中第一指示信息之间的覆盖override。
在一个实施例中，响应于所述第一指示信息仅携带在SIB中，所述确定选中的切片对应的频率优先级包括：
根据所述对应关系确定所述终端所在当前区域对应的当前映射关系；
根据所述当前映射关系确定所述选中的切片对应的目标切片分组；
根据所述第一指示信息确定所述目标切片分组对应的频率优先级；
根据所述目标切片分组对应的频率优先级确定所述选中的切片对应的频率优先级。
在一个实施例中，当第一指示信息仅携带在SIB中时，由于SIB中携带的第一指示信息时，第一指示信息用于指示切片分组对应的频率优先级，因此，在确定切片对应的频率优先级时，需要先确定切片对应的切片分组。
例如，可以先确定终端所在当前区域，进而根据切片相关信息中的所述对应关系，确定当前区域对应的当前映射关系，进而根据当前映射关系确定选中的切片对应的目标切片分组。另一方面，可以根据第一指示信息确定目标切片分组对应的频率优先级，然后根据所述目标切片分组对应的频率优先级确定所述选中的切片对应的频率优先级。
在一个实施例中，响应于所述第一指示信息携带在SIB和RRCRelease消息中，且所述RRCRelease消息中的第一指示信息用于指示切片分组对应的频率优先级，所述确定选中的切片对应的频率优先级包括：
根据所述对应关系确定所述终端所在当前区域对应的当前映射关系；
根据所述当前映射关系确定所述选中的切片对应的目标切片分组；
根据所述RRCRelease消息中的第一指示信息确定所述目标切片分组对应的频 率优先级；
或者
先根据所述RRCRelease消息中的第一指示信息确定所述目标切片分组对应的频率优先级，若未能确定选中的切片对应的频率优先级，根据所述SIB中的第一指示信息确定所述目标切片分组对应的频率优先级。
在一个实施例中，当第一指示信息既携带在SIB中，又携带在RRCRelease消息中时，需要考虑SIB中第一指示信息和RRCRelease消息中第一指示信息的覆盖问题，也即根据SIB中第一指示信息还是RRCRelease消息中第一指示信息确定选中的切片对应的频率优先级。
在一个实施例中，可以是RRCRelease消息中的第一指示信息覆盖SIB中携带的第一指示信息。那么可以忽略SIB中携带的第一指示信息，在RRCRelease消息中的第一指示信息用于指示切片分组对应的频率优先级时，根据切片相关信息中的所述对应关系，确定当前区域对应的当前映射关系，进而根据当前映射关系确定选中的切片对应的目标切片分组，然后根据所述RRCRelease消息中的第一指示信息确定所述目标切片分组对应的频率优先级。
在一个实施例中，也可以综合考虑RRCRelease消息中的第一指示信息和SIB中携带的第一指示信息。例如根据切片相关信息中的所述对应关系，确定当前区域对应的当前映射关系，进而根据当前映射关系确定选中的切片对应的目标切片分组，然后先根据所述RRCRelease消息中的第一指示信息确定目标切片分组对应的频率优先级，若未能确定选中的切片对应的频率优先级，再根据所述SIB中的第一指示信息确定所述目标切片分组对应的频率优先级。据此，有利于确保确定到选中的切片对应的频率优先级。
在一个实施例中，响应于所述第一指示信息携带在SIB和RRCRelease消息中，且所述RRCRelease消息中的第一指示信息用于指示切片对应的频率优先级，所述确定选中的切片对应的频率优先级包括：
根据所述RRCRelease消息中的第一指示信息确定所述选中的切片对应的频率优先级；
或者
先根据所述RRCRelease消息中的第一指示信息确定所述选中的切片对应的频 率优先级，若未能确定选中的切片对应的频率优先级，根据所述对应关系确定所述终端所在当前区域对应的当前映射关系，根据所述当前映射关系确定所述选中的切片对应的目标切片分组，根据所述SIB中的第一指示信息确定所述目标切片分组对应的频率优先级。
在一个实施例中，当第一指示信息既携带在SIB中，又携带在RRCRelease消息中时，需要考虑SIB中第一指示信息和RRCRelease消息中第一指示信息的覆盖问题，也即根据SIB中第一指示信息还是RRCRelease消息中第一指示信息确定选中的切片对应的频率优先级。
在一个实施例中，可以是RRCRelease消息中的第一指示信息覆盖SIB中携带的第一指示信息。那么可以忽略SIB中携带的第一指示信息，在RRCRelease消息中的第一指示信息用于指示切片对应的频率优先级时，可以直接根据RRCRelease消息中的第一指示信息确定选中的切片对应的频率优先级。
在一个实施例中，也可以综合考虑RRCRelease消息中的第一指示信息和SIB中携带的第一指示信息。例如先根据所述RRCRelease消息中的第一指示信息确定选中的切片对应的频率优先级，若未能确定选中的切片对应的频率优先级，可以根据切片相关信息中的所述对应关系，确定当前区域对应的当前映射关系，进而根据当前映射关系确定选中的切片对应的目标切片分组，然后再根据所述SIB中的第一指示信息确定所述目标切片分组对应的频率优先级。据此，有利于确保确定到选中的切片对应的频率优先级。
在一个实施例中，响应于所述第一指示信息携带在SIB和RRCRelease消息中，且所述RRCRelease消息中的第一指示信息用于指示切片对应的频率优先级以及切片分组对应的频率优先级，所述确定选中的切片对应的频率优先级包括：
仅根据所述RRCRelease消息中的第一指示信息中的切片对应的频率优先级确定所述选中的切片对应的频率优先级；
或者
根据所述对应关系确定所述终端所在当前区域对应的当前映射关系，根据所述当前映射关系确定所述选中的切片对应的目标切片分组，仅根据所述RRCRelease消息中的第一指示信息中的切片分组对应的频率优先级，确定所述目标切片分组对应的频率优先级；
或者
先根据所述RRCRelease消息中的第一指示信息中的切片对应的频率优先级确定所述选中的切片对应的频率优先级，若未能确定选中的切片对应的频率优先级，根据所述对应关系确定所述终端所在当前区域对应的当前映射关系，根据所述当前映射关系确定所述选中的切片对应的目标切片分组，根据所述SIB中的第一指示信息确定所述目标切片分组对应的频率优先级；
或者
根据所述对应关系确定所述终端所在当前区域对应的当前映射关系，根据所述当前映射关系确定所述选中的切片对应的目标切片分组，先根据所述RRCRelease消息中的第一指示信息中的切片分组对应的频率优先级确定所述目标切片分组对应的频率优先级，若未能确定选中的切片对应的频率优先级，根据所述SIB中的第一指示信息确定所述目标切片分组对应的频率优先级。
在一个实施例中，当第一指示信息既携带在SIB中，又携带在RRCRelease消息中时，需要考虑SIB中第一指示信息和RRCRelease消息中第一指示信息的覆盖问题，也即根据SIB中第一指示信息还是RRCRelease消息中第一指示信息确定选中的切片对应的频率优先级。
在一个实施例中，可以是RRCRelease消息中的第一指示信息覆盖SIB中携带的第一指示信息，那么可以忽略SIB中携带的第一指示信息。
例如在RRCRelease消息中的第一指示信息用于指示切片对应的频率优先级时，可以直接根据RRCRelease消息中的第一指示信息确定选中的切片对应的频率优先级。
例如在RRCRelease消息中的第一指示信息用于指示切片分组对应的频率优先级时，可以根据切片相关信息中的所述对应关系，确定当前区域对应的当前映射关系，进而根据当前映射关系确定选中的切片对应的目标切片分组，进而根据RRCRelease消息中的第一指示信息中的切片分组对应的频率优先级，确定所述目标切片分组对应的频率优先级。
在一个实施例中，也可以综合考虑RRCRelease消息中的第一指示信息和SIB中携带的第一指示信息。
例如在RRCRelease消息中的第一指示信息用于指示切片对应的频率优先级 时，可以先根据所述RRCRelease消息中的第一指示信息确定选中的切片对应的频率优先级，若未能确定选中的切片对应的频率优先级，可以根据切片相关信息中的所述对应关系，确定当前区域对应的当前映射关系，进而根据当前映射关系确定选中的切片对应的目标切片分组，然后再根据所述SIB中的第一指示信息确定所述目标切片分组对应的频率优先级。
例如在RRCRelease消息中的第一指示信息用于指示切片分组对应的频率优先级时，根据切片相关信息中的所述对应关系，确定当前区域对应的当前映射关系，进而根据当前映射关系确定选中的切片对应的目标切片分组，然后先根据所述RRCRelease消息中的第一指示信息确定目标切片分组对应的频率优先级，若未能确定选中的切片对应的频率优先级，再根据所述SIB中的第一指示信息确定所述目标切片分组对应的频率优先级。
需要说明的是，以上有关第一指示信息的实施例以及后续有关第二指示信息的实施例，当指示信息携带在SIB和RRCRelease消息中时，在考虑覆盖时，主要考虑的是RRCRelease消息中指示信息对SIB中指示信息的覆盖，但是实际上可以根据需要进行调整，也可以设置SIB中指示信息对RRCRelease消息中指示信息覆盖。
图4是根据本公开的实施例示出的又一种关系指示方法的示意流程图。如图4所示，所述方法还包括：
在步骤S401中，按照所述频率优先级由高到低选择频率，确定选中的频率对应的所有小区的排名；
在步骤S402中，按照排名由高到低确定排名最高的小区，确定排名最高的小区是否支持所述选中的切片，若所述排名最高的小区支持所述选中的切片，则重选到所述排名最高的小区，若所述选中的排名最高的小区不支持所述选中的切片，选择下一个优先级的频率。
在一个实施例中，在确定选中的切片对应的频率优先级之后，可以按照频率优先级由高到低选择频率，进而确定选中的频率对应的所有小区的排名(例如根据R准则进行排名)。
其中，确定排名的方式可以按照R准则进行，例如考虑因素至少包括小区的信号质量，信号质量越大排名越高。
进而可以按照排名由高到低选择小区，然后确定选中的小区是否支持选中的切 片。若选中的小区支持选中的切片，那么可以重选到选中的小区，例如选中的小区为排名最高的小区，那么可以重选到该小区；若选中的小区不支持选中得到切片，那么可以选择下一个优先级的频率，也即针对下一个优先级的频率确定对应的所有小区中排名最高的小区是否支持选中的切片。据此，有利于确保重选到的小区是选中的频率对应的最合适的小区，进而确保重选小区后良好的通信质量。
需要说明的是，在选中的小区不支持选中得到切片时，本实施例的另一种实现方式可以是选择下一个优先级的小区，并判断选中的小区是否支持选中的切片，以此类推，直至确定到支持选中的切片的小区，或者遍历了选中的频率对应的所有小区，那么再选择下一个优先级的频率。据此，可以相对全面地考虑频率对应的所有小区。
图5是根据本公开的实施例示出的又一种关系指示方法的示意流程图。如图5所示，所述确定选中的小区是否支持所述选中的切片包括：
在步骤S501中，根据所述网络侧设备的发送的第二指示信息确定选中的小区是否支持所述选中的切片，其中，所述第二指示信息用于指示小区支持的切片信息。
在一个实施例中，网络侧设备可以通过第二指示信息向终端指示小区支持的切片信息，第二指示信息所指示的小区可以包括一个或多个小区，并且所指示的小区可以包括非特定小区，也可以包括特定小区。终端在选中小区后，可以根据第二指示信息确定选中的小区是否支持选中的切片。
在一个实施例中，所述第二指示信息携带在以下至少之一中：
系统信息块SIB：
无线资源控制释放RRCRelease消息。
在一个实施例中，在所述第二指示信息携带在SIB中时，所述第二指示信息用于指示小区支持的切片分组；
在所述第二指示信息携带在RRCRelease消息中时，所述第二指示信息用于指示小区支持的切片和/或切片分组。
在一个实施例中，SIB携带的切片信息相关的信息，可以包括切片分组相关的信息；RRCRelease消息携带的切片信息相关的信息，可以包括切片分组相关的信息，可以包括单个切片相关的信息。
其中，切片信息相关的信息，包括但不限于切片信息对应的频率优先级、小区 支持的切片信息。
例如在切片信息相关的信息包括切片信息对应的频率优先级时，SIB中携带的第一指示信息可以指示切片分组对应的频率优先级；RRCRelease消息携带的第一指示信息可以指示切片分组对应的频率优先级，和/或指示切片对应的频率优先级。
例如在切片信息相关的信息包括小区支持的切片信息时，SIB中携带的第二指示信息可以指示小区支持的切片分组；RRCRelease消息携带的第二指示信息可以指示小区支持的切片分组，和/或指示小区支持的切片。
在一个实施例中，在所述第二指示信息携带在SIB中时，所述第二指示信息用于指示小区支持的切片分组；
在所述第一指示信息携带在RRCRelease消息中时，所述第一指示信息用于指示小区支持的切片和/或切片分组。
由于SIB一般为网络侧设备广播的消息，可能不被特定的终端接收到，在一定程度上会存在安全问题，因此在第二指示信息携带在SIB中时，可以不指示具体小区支持的切片，而是指示小区支持的切片分组。
而RRCRelease则是单播消息，只会被特定的终端接收到，所以一般并不会存在类似SIB消息的安全问题，因此在第二指示信息携带在RRCRelease中时，可以指示小区支持的具体切片，也可以指示小区支持的切片分组，具体可以根据需要设置。
在一个实施例中，响应于所述第二指示信息仅携带在SIB中，所述确定选中的小区是否支持所述选中的切片还包括：
根据所述第二指示信息指示的小区支持的切片分组，确定所述选中的小区支持的切片分组；
根据网络侧设备发送的区域信息，确定所述选中的小区所属的目标区域；
根据所述对应关系确定所述目标区域对应的目标映射关系；
根据所述映射关系所述选中的小区支持的切片分组确定所述选中的小区支持的切片。
在一个实施例中，当第二指示信息仅携带在SIB中时，由于SIB中携带的第二指示信息时，第二指示信息用于指示小区支持的切片分组，因此，在确定小区支持的切片时，需要先确定切片对应的切片分组。
例如，可以先确定选中的小区所属的目标区域，进而根据切片相关信息中的所述对应关系，确定目标区域对应的目标映射关系，进而根据目标映射关系选中的小区支持的切片分组确定选中的小区支持的切片。
其中，根据目标映射关系选中的小区支持的切片分组确定选中的小区支持的切片主要可以包括两种方式：
根据目标映射关系确定选中的切片对应的目标切片分组，以及根据目标映射关系确定小区支持的切片分组，然后判断目标切片分组与小区支持的切片分组是否相同，若相同，可以确定小区支持选中的切片，若不同，可以确定小区不支持选中的切片(同一个切片不会映射到不同分组)。
根据目标映射关系确定小区支持的切片分组对应目标切片，判断选中的切片是否包含在目标切片中，若包含在目标切片中，可以确定小区支持选中的切片，若不包含在目标切片中，可以确定小区不支持选中的切片(同一个切片不会映射到不同分组)。
需要说明的是，网络侧设备发送的区域信息，可以包括TA(可以包括当前所在TA和当前所在TA的邻TA)的信息，例如TA的标识TAC，也可以包括小区(可以包括当前所在小区和当前所在小区的邻小区)的信息，例如小区的标识Cell ID。终端在确定选中的小区后，可以确定选中的小区对应的区域信息，进而根据选中的小区对应的区域信息确定选中的小区所属的目标区域。例如确定选中的小区对应的区域信息为TA1的标识，那么可以确定选中的小区属于TA1。
在一个实施例中，响应于所述第二指示信息携带在SIB和RRCRelease消息中，且所述RRCRelease消息中的第二指示信息用于指示小区支持的切片分组，所述确定选中的小区是否支持所述选中的切片还包括：
根据所述RRCRelease消息中的第二指示信息确定所述选中的小区支持的切片分组，根据网络侧设备发送的区域信息，确定所述选中的小区所属的目标区域，根据所述对应关系确定所述目标区域对应的目标映射关系，根据所述映射关系和所述选中的小区支持的切片分组确定所述选中的小区支持的切片；
或者
先根据所述RRCRelease消息中的第二指示信息确定所述选中的小区支持的切片分组，若未能确定所述选中的小区支持的切片分组，根据所述SIB中的第二指示信息确定所述选中的小区支持的切片分组，根据网络侧设备发送的区域信息，确定所述 选中的小区所属的目标区域，根据所述对应关系确定所述目标区域对应的目标映射关系，根据所述映射关系和所述选中的小区支持的切片分组确定所述选中的小区支持的切片。
在一个实施例中，当第二指示信息既携带在SIB中，又携带在RRCRelease消息中时，需要考虑SIB中第二指示信息和RRCRelease消息中第二指示信息的覆盖问题，也即根据SIB中第二指示信息还是RRCRelease消息中第二指示信息确定小区支持的切片。
在一个实施例中，可以是RRCRelease消息中的第二指示信息覆盖SIB中携带的第二指示信息。那么可以忽略SIB中携带的第二指示信息，在RRCRelease消息中的第二指示信息用于指示小区支持的切片分组时，根据所述RRCRelease消息中的第二指示信息确定选中的小区支持的切片分组，根据网络侧设备发送的区域信息，确定选中的小区所属的目标区域，根据切片相关信息中的所述对应关系确定目标区域对应的目标映射关系，根据所述映射关系和所述选中的小区支持的切片分组确定所述选中的小区支持的切片。
在一个实施例中，也可以综合考虑RRCRelease消息中的第二指示信息和SIB中携带的第二指示信息。例如先根据所述RRCRelease消息中的第二指示信息确定选中的小区支持的切片分组，若未能确定所述选中的小区支持的切片分组，则根据所述SIB中的第二指示信息确定所述选中的小区支持的切片分组。然后再根据网络侧设备发送的区域信息，确定所述选中的小区所属的目标区域，根据所述对应关系确定所述目标区域对应的目标映射关系，根据所述映射关系和所述选中的小区支持的切片分组确定所述选中的小区支持的切片。据此，有利于确保确定到选中的小区支持的切片分组。
在一个实施例中，响应于所述第二指示信息携带在SIB和RRCRelease消息中，且所述RRCRelease消息中的第二指示信息用于指示小区支持的切片，所述确定选中的小区是否支持所述选中的切片还包括：
根据所述RRCRelease消息中的第二指示信息确定所述选中的小区支持的切片；
或者
先根据所述RRCRelease消息中的第二指示信息确定所述选中的小区支持的切片，若未能确定所述选中的小区支持的切片，根据所述SIB中的第二指示信息确定所 述选中的小区支持的切片分组，根据网络侧设备发送的区域信息，确定所述选中的小区所属的目标区域，根据所述对应关系确定所述目标区域对应的目标映射关系，根据所述映射关系和所述选中的小区支持的切片分组确定所述选中的小区支持的切片。
在一个实施例中，当第二指示信息既携带在SIB中，又携带在RRCRelease消息中时，需要考虑SIB中第二指示信息和RRCRelease消息中第二指示信息的覆盖问题，也即根据SIB中第二指示信息还是RRCRelease消息中第二指示信息确定选中的切片对应的频率优先级。
在一个实施例中，可以是RRCRelease消息中的第二指示信息覆盖SIB中携带的第二指示信息。那么可以忽略SIB中携带的第二指示信息，在RRCRelease消息中的第二指示信息用于指示小区支持的切片时，可以直接根据RRCRelease消息中的第二指示信息确定选中的小区支持的切片。
在一个实施例中，也可以综合考虑RRCRelease消息中的第二指示信息和SIB中携带的第二指示信息。例如先根据所述RRCRelease消息中的第二指示信息确定选中的小区支持的切片，若未能确定选中的小区支持的切片，根据所述SIB中的第二指示信息确定选中的小区支持的切片分组，再根据网络侧设备发送的区域信息，确定所述选中的小区所属的目标区域，根据所述对应关系确定所述目标区域对应的目标映射关系，根据所述映射关系和所述选中的小区支持的切片分组确定所述选中的小区支持的切片。据此，有利于确保确定到选中的小区支持的切片。
在一个实施例中，响应于所述第二指示信息携带在SIB和RRCRelease消息中，且所述RRCRelease消息中的第二指示信息用于指示小区支持的切片分组以及小区支持的切片，所述确定选中的小区是否支持所述选中的切片还包括：
根据所述RRCRelease消息中的第二指示信息中的小区支持的切片确定所述选中的小区支持的切片；
或者
根据所述RRCRelease消息中的第二指示信息中的小区支持的切片分组确定所述选中的小区支持的切片分组，根据网络侧设备发送的区域信息，确定所述选中的小区所属的目标区域，根据所述对应关系确定所述目标区域对应的目标映射关系，根据所述映射关系和所述选中的小区支持的切片分组确定所述选中的小区支持的切片；
或者
先根据所述RRCRelease消息中的第二指示信息中的小区支持的切片确定所述选中的小区支持的切片，若未能确定所述选中的小区支持的切片，根据所述SIB中的第二指示信息确定所述选中的小区支持的切片分组，根据网络侧设备发送的区域信息，确定所述选中的小区所属的目标区域，根据所述对应关系确定所述目标区域对应的目标映射关系，根据所述映射关系和所述选中的小区支持的切片分组确定所述选中的小区支持的切片；
或者
根据网络侧设备发送的区域信息，确定所述选中的小区所属的目标区域，根据所述对应关系确定所述目标区域对应的目标映射关系，先根据所述RRCRelease消息中的第二指示信息中的小区支持的切片分组确定所述选中的小区支持的切片分组，若未能确定所述选中的小区支持的切片分组，根据所述SIB中的第二指示信息确定所述选中的小区支持的切片分，根据所述映射关系和所述选中的小区支持的切片分组确定所述选中的小区支持的切片。
在一个实施例中，当第二指示信息既携带在SIB中，又携带在RRCRelease消息中时，需要考虑SIB中第二指示信息和RRCRelease消息中第二指示信息的覆盖问题，也即根据SIB中第二指示信息还是RRCRelease消息中第二指示信息确定选中的切片对应的频率优先级。
在一个实施例中，可以是RRCRelease消息中的第二指示信息覆盖SIB中携带的第一指示信息，那么可以忽略SIB中携带的第二指示信息。
例如在RRCRelease消息中的第二指示信息用于指示小区支持的切片时，可以直接根据RRCRelease消息中的第二指示信息确定选中的小区支持的切片。
例如在RRCRelease消息中的第二指示信息用于指示选中的小区支持的切片分组时，可以根据所述RRCRelease消息中的第二指示信息中的小区支持的切片分组确定所述选中的小区支持的切片分组，然后根据网络侧设备发送的区域信息，确定所述选中的小区所属的目标区域，再根据所述对应关系确定所述目标区域对应的目标映射关系，最后根据所述映射关系和所述选中的小区支持的切片分组确定所述选中的小区支持的切片。
在一个实施例中，也可以综合考虑RRCRelease消息中的第二指示信息和SIB中携带的第二指示信息。
例如在RRCRelease消息中的第二指示信息用于指示小区支持的切片时，可以先根据所述RRCRelease消息中的第二指示信息确定选中的小区支持的切片，若未能确定选中的小区支持的切片，可以根据所述SIB中的第二指示信息确定所述选中的小区支持的切片分组，根据网络侧设备发送的区域信息，确定所述选中的小区所属的目标区域，根据所述对应关系确定所述目标区域对应的目标映射关系，根据所述映射关系和所述选中的小区支持的切片分组确定所述选中的小区支持的切片。
例如在RRCRelease消息中的第二指示信息用于指示小区支持的切片分组时，可以根据切片相关信息中的所述对应关系确定所述目标区域对应的目标映射关系，然后先根据所述RRCRelease消息中的第二指示信息中的小区支持的切片分组确定所述选中的小区支持的切片分组，若未能确定所述选中的小区支持的切片分组，根据所述SIB中的第二指示信息确定所述选中的小区支持的切片分，根据所述映射关系和所述选中的小区支持的切片分组确定所述选中的小区支持的切片。
以上实施例描述了在NAS层向AS层发送切片分组与切片之间的映射关系时，在SIB携带了切片信息相关的信息，且RRCRelease消息也携带了切片信息相关的信息时，确定SIB中切片信息相关的信息与RRCRelease消息中切片信息相关的信息之间的覆盖问题。
以下通过几个实施例描述在NAS层并未向AS层发送切片分组与切片之间的映射关系，NAS层仅向AS层指示切片对应的切片分组标识时，SIB中切片信息相关的信息与RRCRelease消息中切片信息相关的信息之间的覆盖问题。
例如以切片信息相关的信息为切片信息对应的频率优先级(可以替换为小区支持的切片信息)为例。
在一个实施例中，在SIB指示了切片分组对应的频率优先级，且RRCRelease消息也指示了切片分组对应的频率优先级的情况下。
可以忽略SIB中指示的切片分组对应的频率优先级，根据切片相关信息中的所述对应关系，确定当前区域对应的当前映射关系，进而根据当前映射关系确定选中的切片对应的目标切片分组，然后根据所述RRCRelease消息指示的切片分组对应的频率优先级，确定所述目标切片分组对应的频率优先级。
或者，可以综合考虑RRCRelease消息指示的切片分组对应的频率优先级和SIB指示的切片分组对应的频率优先级。例如根据切片相关信息中的所述对应关系，确定 当前区域对应的当前映射关系，进而根据当前映射关系确定选中的切片对应的目标切片分组，然后先根据所述RRCRelease消息指示的切片分组对应的频率优先级确定目标切片分组对应的频率优先级，若未能确定选中的切片对应的频率优先级，再根据所述SIB指示的切片分组对应的频率优先级确定所述目标切片分组对应的频率优先级。
在一个实施例中，在SIB指示了切片分组对应的频率优先级，且RRCRelease消息指示了切片对应的频率优先级的情况下。
由于NAS层仅向AS层指示切片对应的切片分组标识，所以AS层并不能理解RRCRelease消息所指示的切片对应的频率优先级。
因此可以根据切片相关信息中的所述对应关系，确定当前区域对应的当前映射关系，进而根据当前映射关系确定选中的切片对应的目标切片分组，然后根据所述SIB指示的切片分组对应的频率优先级，确定所述目标切片分组对应的频率优先级。这种情况相当于SIB指示的切片分组对应的频率优先级，覆盖了RRCRelease消息指示的切片分组对应的频率优先级。
或者，可以确定SIB指示的传统legacy频率优先级用于小区重选。这种情况相当于RRCRelease消息指示的切片分组对应的频率优先级，覆盖了SIB指示的切片分组对应的频率优先级，但是由于AS层并不能理解RRCRelease消息所指示的切片对应的频率优先级，所有会回退到根据SIB指示的传统legacy频率优先级进行小区重选。
在一个实施例中，在SIB指示了切片分组对应的频率优先级，且RRCRelease消息指示了切片分组和切片对应的频率优先级的情况下。
可以忽略SIB中指示的切片分组对应的频率优先级，根据切片相关信息中的所述对应关系，确定当前区域对应的当前映射关系，进而根据当前映射关系确定选中的切片对应的目标切片分组，然后根据RRCRelease消息指示的切片分组对应的频率优先级，确定所述目标切片分组对应的频率优先级。
或者，忽略SIB中指示的切片分组对应的频率优先级，根据切片相关信息中的所述对应关系，确定当前区域对应的当前映射关系，进而根据当前映射关系确定选中的切片对应的目标切片分组，然后优先根据RRCRelease消息指示的切片分组对应的频率优先级，确定所述目标切片分组对应的频率优先级。若未能确定选中的切片对应的频率优先级，确定SIB指示的传统legacy频率优先级用于小区重选。
或者，根据切片相关信息中的所述对应关系，确定当前区域对应的当前映射关 系，进而根据当前映射关系确定选中的切片对应的目标切片分组，然后优先根据RRCRelease消息指示的切片分组对应的频率优先级，确定所述目标切片分组对应的频率优先级。若未能确定选中的切片对应的频率优先级，根据SIB指示的切片分组对应的频率优先级，确定所述目标切片分组对应的频率优先级。

由于SIB一般为网络侧设备广播的消息，可能不被特定的终端接收到，在一定程度上会存在安全问题，因此在第一指示信息携带在SIB中时，可以不指示具体切片对应的频率优先级，而是指示切片分组对应的频率优先级。
而RRCRelease则是单播消息，只会被特定的终端接收到，所以一般并不会存在类似SIB消息的安全问题，因此在第一指示信息携带在RRCRelease中时，可以指 示具体切片对应的频率优先级，也可以指示切片分组对应的频率优先级，具体可以根据需要设置。
在一个实施例中，向上述任一实施例所述的终端传输信息包括：
向所述终端发送第二指示信息，用于指示小区支持的切片信息。

由于SIB一般为网络侧设备广播的消息，可以被不特定的终端接收到，在一定程度上会存在安全问题，因此在第二指示信息携带在SIB中时，可以不指示具体小区支持的切片，而是指示小区支持的切片分组。
而RRCRelease则是单播消息，只会被特定的终端接收到，所以一般并不会存在类似SIB消息的安全问题，因此在第二指示信息携带在RRCRelease中时，可以指示小区支持的具体切片，也可以指示小区支持的切片分组，具体可以根据需要设置。
在一个实施例中，向上述任一实施例所述的终端传输信息还包括：
向所述终端发送区域信息，用于供所述终端确定选中的小区所属的目标区域。
