一种信令传输的方法、设备及计算机存储介质
相关申请的交叉引用
本申请要求在2018年09月28日提交中国专利局、申请号为201811140777.2、申请名称为“一种信令传输的方法、设备及计算机存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，尤其是涉及一种信令传输的方法、设备及计算机存储介质。
背景技术
在5G移动通信系统中，由于存在大量的频带组合，导致一些信令消息(例如UE能力信息消息)的大小非常大，超出了分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)协议数据单元(Protocol Data Unit，PDU)的最大长度(9000字节)限制。
例如，在下行系统消息块(SystemInformationBlock，SIB)分段机制中，由于SIB消息是透明模式(Transparent Mode，TM)传输的消息，所以无法在无线链路层控制协议(Radio Link Control，RLC)层进行分段，且每个数据块均不能超出物理层传输限制。而来自核心网的下行地震及海啸预警系统(Earthquake and Tsunami Warning Systerm，ETWS)和商业移动警报服务(Commercial Mobile Alert Service，CMAS)消息需要通过广播发送，其大小可能超出SIB限制。
在现有技术中，长期演进(Long Term Evolution，LTE)系统采用的解决机制是将来自核心网的ETWS和CMAS消息作为数据流进行分段，并在消息中包含分段信息，用户设备(User Equipment，UE)收到分段消息后将分段消息对应的数据流按照分段号进行串接。但这种分段方式通常适用于将非接入 层的信息封装在无线资源控制(Radio Resource Control，RRC)层进行传输的情况，这是因为对于RRC层的信令需要RRC层按照抽象语法标记(Abstract Syntax Notation One，ASN.1)结构进行解析，而RRC层并不能解析被分段的数据，所以采用这种分段方式只能进行简单的分段消息拆分和级联，而无法直接使用解析消息内容后获得的分段消息再解析原消息。
鉴于此，如何对大的控制面信令进行传输，成为一个亟待解决的技术问题。其中，大的控制面信令指信令长度较大的控制面信令。
发明内容

具体实施方式
本申请实施列提供一种信令传输的方法、设备及计算机存储介质，以解决现有技术中存在的不能对大的控制面信令进行传输的技术问题。
本申请实施例中的技术方案为解决上述的技术问题，总体思路如下：
提供一种信令传输方法，应用于发送设备，该方法包括：将无线资源控制RRC信令按约定传输方式分割为多条RRC关联消息；其中，每条RRC关联消息的大小不大于分组数据聚合协议PDCP支持的最大信令长度，约定传输方式为在传输大于最大信令长度的RRC信令时采用的分段传输方式，RRC关联消息为显式或隐式携带有RRC信令被分割后的关联信息的RRC消息；发送多条RRC关联消息给接收设备，使接收设备按约定传输方式将多条RRC关联消息合并为RRC信令。
由于在上述方案中，在传输大于最大信令长度的RRC信令时，通过将无线资源控制RRC信令按约定传输方式分割为多条RRC关联消息，且每条RRC关联消息的大小不大于分组数据聚合协议PDCP支持的最大信令长度，并在RRC关联消息中显式或隐式携带RRC信令被分割后的关联信息的RRC消息，随后将多条RRC关联消息发送给接收设备，使接收设备按约定传输方式将多条RRC关联消息合并为RRC信令，从而让大的控制面信令得以在RRC层进行传输。
为了更好的理解上述技术方案，下面通过附图以及具体实施例对本申请技术方案做详细的说明，应当理解本申请实施例以及实施例中的具体特征是对本申请技术方案的详细的说明，而不是对本申请技术方案的限定，在不冲突的情况下，本申请实施例以及实施例中的技术特征可以相互组合。
请参考图1，本申请实施例提供一种信令传输方法，应用于发送设备，该方法的处理过程如下。
步骤101：将无线资源控制RRC信令按约定传输方式分割为多条RRC关 联消息；其中，每条RRC关联消息的大小不大于分组数据聚合协议PDCP支持的最大信令长度，约定传输方式为在传输大于最大信令长度的RRC信令时采用的分段传输方式，RRC关联消息为显式携带有RRC信令被分割后的关联信息的RRC消息；或者RRC关联消息为隐式携带有RRC信令被分割后的关联信息的RRC消息。
步骤102：发送多条RRC关联消息给接收设备，使接收设备按约定传输方式将多条RRC关联消息合并为RRC信令。
具体的，约定传输方式根据消息结构的不同可以采用以下两种传输方式：
第一种，约定传输方式为使用相同消息结构传输多条RRC关联消息；其中，相同消息结构至少由一条包含部分RRC信令的RRC关联消息及与多条RRC关联消息中其它RRC关联消息相关的关联信息构成。
例如，请参见图2以用户终端需要向网络侧发送UE能力消息(即RRC信令)为例，若传输协议中定义UE能力消息可以通过多条传输消息同时传输UE能力消息，则将UE能力消息分割为多个不同部分(与定义的可同时使用的传输消息数量相同)，例如分割为3个不同部分，分别为UE能力1、UE能力2、UE能力3，并加入各自的关联信息获得3条RRC关联消息，其中以关联信息为各部分的消息编号(如ID1、ID2、ID3)为例。将这3条RRC关联消息发送给网络侧，使网络侧将这3条RRC关联消息中的3部分UE能力按消息编号的顺序串接为一条RRC信令(即UE能力消息)。
第二种，约定传输方式为使用不同消息结构分多次传输多条RRC关联消息；其中，不同消息结构至少由一条包含RRC信令中不同参数的RRC关联消息及与多条RRC关联消息中其它RRC关联消息相关的关联信息构成。
例如，仍然以用户终端需要向网络侧发送UE能力消息(即RRC信令)为例，请参见图3，UE能力消息包括UE能力1至UE能力6，若传输协议中定义UE能力消息只能通过一条传输消息进行传输，则UE根据PDCP的大小限制，将UE能力1至UE能力6组装成2条RRC关联消息分次进行上报。其中，UE能力1为必选能力，将关联信息设置在必选能力(即UE能力1) 中，UE能力的值越高代表能力越强，第一次发送的RRC关联消息的关联信息为关联消息数为2、关联消息编号为0，第二次发送的RRC关联消息的关联信息为关联消息数为2、关联消息编号为1。UE将这2条RRC关联消息分2次进行上报，使接收设备将这2条RRC关联消息合并为一条RRC信令(即UE能力消息)。
需要理解的是，在上述发送设备的实施例中，关联信息可以是：消息名称之间的关联关系、消息名称编号、消息关联标识、关联消息指示、消息个数、消息编号、是否最后一条消息、当前关联消息之后是否还有其它关联消息中的任一种及任一组合。
下面针对上述关联信息的几种形式做简要举例：
1、消息名称之间的关联关系，例如可以是“相同消息名称+不同消息编号”，通过编号的顺序确定RRC关联消息之间的逻辑关系。
1)若RRC关联消息使用的是相同的消息结构，则在将一RRC信令分割为多条RRC关联消息进行传输前。可以通过下列程序示例的形式定义每条RRC关联消息(以上行的RRC关联消息为例)：
Figure PCTCN2019101840-appb-000001
其中，ueCapabilityInformation即为各条RRC关联消息使用的相同消息名称，1、2、3为各条RRC关联消息的不同编号，UECapabilityInformation为RRC关联消息使用的消息结构。
2)若RRC关联消息使用的是不同的消息结构，则在将一RRC信令分割 为多条RRC关联消息进行传输前。可以通过下列程序示例的形式定义每条RRC关联消息(以上行的RRC关联消息为例)：
Figure PCTCN2019101840-appb-000002
其中，ueCapabilityInformation即为各条RRC关联消息使用的相同消息名称，1、2、3为各条RRC关联消息的不同消息编号，UECapabilityInformation1、UECapabilityInformation2、UECapabilityInformation3代表3种不同的消息结构。
2、消息名称编号：在RRC关联消息的定义中增加消息编号，例如UECapabilityInformation中包含3部分
Figure PCTCN2019101840-appb-000003
其中，UECapabilityInformation为一条RRC信令，它被分割为3条RRC关联消息ueCapabilityInformation1-3，它们可以采用不同的消息结构UECapabilityInformation1-3。
3、消息关联标识，消息编号：在RRC关联消息的定义中增加一个编号指示当前为第几条关联消息，以UE能力为例：
Figure PCTCN2019101840-appb-000004
Figure PCTCN2019101840-appb-000005
其中，segmentNumber代表RRC关联消息为的编号。
4、关联消息指示，例如可以在每条RRC关联消息中用一个特定的值如segmentIndication来标识其是否为关联消息，若segmentIndication为布尔量，则segmentIndication可以为1，即用1标识某条消息为RRC关联消息，也可以用其它标识符号进行标识，具体不做限定。关联消息指示的程序示例如下：
Figure PCTCN2019101840-appb-000006
其中，segmentIndication为关联消息指示，BOOLEAN为布尔型变量。
5、消息个数，在RRC关联消息的消息定义中可以通过增加一个参数指示RRC信令共由几条RRC关联消息组成。以UE能力为例的程序示例如下：
Figure PCTCN2019101840-appb-000007
其中，totalSegmentNumber为RRC信令被分割为RRC关联消息的数量，INTEGER代表totalSegmentNumber的数据类型为整数型。
6、RRC关联消息是否最后一条消息，可以在RRC关联消息的定义中增加一个参数指示是否为最后一条关联消息，以UE能力为例：
Figure PCTCN2019101840-appb-000008
Figure PCTCN2019101840-appb-000009
其中，lastSegment为最后一条消息标识符。
7、当前关联消息之后是否还有其它关联消息，在RRC关联消息的定义中还可以增加一个参数指示后续是否还有与之相关联的RRC关联消息，以UE能力为例：
Figure PCTCN2019101840-appb-000010
其中，noMore用于标识后续是否还有与之相关联的RRC关联消息，例如noMore为1则后续还有与之关联的RRC关联消息，noMore为0则后续没有与之关联的RRC关联消息。
由于在实际的RRC关联消息中，上述信息可以只有一个存在于RRC关联信息中，例如都是用消息编号，让接收设备按消息编号的顺序进行合并(事先约定消息编号的总数)，也可以是消息编号加消息总数，还可以是当前关联消息之后是否还有其它关联消息等组合的情况形成关联信息，由于组合形式众多，故不再进行穷举。
在发送设备将多个RRC关联消息发送给接收设备之后，接收设备的处理过程请参见以下的介绍。
请参见图4，基于同一发明构思，本申请一实施例中提供一种信令传输方法，应用于接收设备，该方法的处理过程如下。
步骤401：按约定传输方式接收多条RRC关联消息；其中，每条RRC关联消息的大小不大于分组数据聚合协议PDCP支持的最大信令长度，且RRC关联消息为显式或隐式携带有RRC信令被分割后的关联信息的RRC消息， 约定传输方式为在传输大于最大信令长度的RRC信令时采用的分段传输方式；
步骤402：将多条RRC关联消息解析后合并为一条RRC信令。
具体的，将多条RRC关联消息解析后合并为一条RRC信令，可以先按ASN.1结构对多条RRC关联消息分别进行解析，获得每条RRC关联消息中的消息参数；再根据RRC关联消息中携带的关联信息，按预设规则将每条RRC关联消息中的消息参数合并为RRC信令。
根据发送设备采用的2种消息结构，接收设备在接收到发送设备发送的多条RRC信令之后，在将多条RRC关联消息解析合并为一条RRC信令时，相应的也有2种方式，具体如下：
第一种，针对多条RRC关联消息的每条RRC关联消息都采用相同的结构，接收设备将多条RRC关联消息解析后合并为一条RRC信令时使用的预设规则是隐含的规则，即隐含将多条传输消息按关联信息进行串接，合并为一条RRC信令。
例如，以前述发送设备发送的图2中的例子为例，在接收设备接收到3条RRC关联消息之后，根据ASN.1结构对每条RRC关联消息进行解析分别获得UE能力1、UE能力2、UE能力3，及它们对应的关联信息(ID1、ID2、ID3)，根据ID1、ID2、ID3将UE能力1、UE能力2、UE能力3依次串接为一条RRC信令(即UE能力消息)。
第二种，针对多条RRC关联消息的每条RRC关联消息采用不同的结构，接收设备分多次接收到多条RRC关联消息之后，将多条RRC关联消息解析后合并为一条RRC信令时使用的预设规则具体为：
在对多条RRC关联消息中的参数进行合并时，对于同一参数用设有取值的参数值取代未设取值的参数值；其中，每条RRC关联消息中具有多个参数；若多条RRC关联消息中有至少两条RRC关联消息对同一参数都设有取值，当在RRC关联消息中对同一参数设置了相同取值，则同一参数取RRC关联消息的相同取值；若至少两条RRC关联消息取值不同，则同一参数取至少两条RRC关联消息中取值最高或取值最低的RRC关联消息中对应参数的值； 或，若至少两条RRC关联消息取值不同，则同一参数取最后一条RRC关联消息中的对应参数的值。
例如，以前述发送设备发送的图3中的例子为例，由于第一次发送的RRC关联消息中只有UE能力1至UE能力4，第二次发送的RRC关联消息中只有UE能力1、UE能力4和UE能力5，所以根据上述预设规则假设对同一参数都设有取值时取最高值，则由于第一次发送的RRC关联消息中的UE能力的值为1、第二次发送的UE能力的值为2，所以在合并时取UE能力1的值取2，又由于UE能力2至UE能力6在第一次和第二发送的RRC关联消息中并未重复出现，所以直接按照RRC关联消息中的关联信息确定一共有2条RRC关联信息解析后的参数(即UE能力)进行合并，得到一条RRC信令(即UE能力消息)如图5所示。
需要理解的是，在上述接收设备的实施例中关联信息，可以是：消息名称之间的关联关系、消息名称编号、消息关联标识、关联消息指示、消息个数、消息编号、是否最后一条消息、当前关联消息之后是否还有其它关联消息中的任一种及任一组合。由于上述关联消息与发送设备侧的关联消息一致，为免赘述不再举例，具体可参见发送设备侧的信令传输方法里的举例。
需要说明的是，随着通信技术的不断发展，当网络侧需要发送的信令大于PDCP规定的大小时，发送设备也可以是网络侧，相应的接收设备为终端侧。反之，终端侧也可以作为发送设备，相应的网络侧则作为接收设备。故，发送设备或接收设备具体为网络侧还是终端侧不做限定。
