相关申请的交叉引用
本申请主张在2018年1月11日在中国提交的中国专利申请号No.201810026262.3的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种系统信息的传输方法和用户终端。
背景技术
无线通信系统的系统信息(System Information，SI)主要分为主信息块(Master Information Block，MIB)和多个系统信息块(System Information Blocks，SIBs)，其中，系统信息块可以包括SIB1～SIB20等系统信息。在实际应用中，很多场景是需要广播系统信息的，且目前每次广播都是广播所有系统信息，即包括MIB、SIB1和SI这些系统信息，其中SI包含SIB2～SIB20，当然，还可能继续扩展。这样用户终端可能会接收到用户不需要的系统信息，从而导致用户终端的功耗较大，以及无线通信系统中系统信息开销过大。
发明内容
本公开实施例提供一种系统信息的传输方法和用户终端，以解决用户终端的功耗较大，以及无线通信系统中系统信息开销过大的问题。
为了解决上述技术问题，本公开是这样实现的：一种系统信息的传输方法，应用于用户终端，包括：
通过随机接入过程中的上行消息向基站发送系统信息请求；
若所述随机接入过程成功，则不设置小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)，并接收所述基站发送的所述系统信息请求对应的系统信息。
第一方面，本公开实施例还提供了一种系统信息的传输方法，应用于用 户终端，包括：
通过随机接入过程中的上行消息向基站发送系统信息请求；
若所述随机接入过程成功，则不设置C-RNTI，并接收所述基站发送的所述系统信息请求对应的系统信息。
第二方面，本公开实施例提供了一种用户终端，包括：
第一发送模块，用于通过随机接入过程中的上行消息向基站发送系统信息请求；
第一接收模块，用于若所述随机接入过程成功，则不设置C-RNTI，并接收所述基站发送的所述系统信息请求对应的系统信息。
第三方面，本公开实施例提供了一种用户终端，包括：存储器、处理器及存储在所述存储器上并可在所述处理器上运行的计算机程序，所述计算机程序被所述处理器执行时实现本公开实施例提供的系统信息的传输方法中的步骤。
第四方面，本公开实施例提供了一种计算机可读存储介质，所述计算机可读存储介质上存储有计算机程序，所述计算机程序被处理器执行时实现本公开实施例提供的系统信息的传输方法的步骤。
在本公开实施例中，通过随机接入过程中的上行消息向基站发送系统信息请求；若所述随机接入过程成功，则不设置C-RNTI，并接收所述基站发送的所述系统信息请求对应的系统信息。这样可以实现用户终端只接收请求的系统信息，节约用户终端功耗和系统信息的开销。另外，由于不设置C-RNTI从而用户终端不会持续进行控制信道的监听，更进一步节约用户终端的功耗。

为了更清楚地说明本公开实施例的技术方案，下面将对本公开实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

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，都属于本公开保护的范围。
请参见图1，图1是本公开实施例可应用的一种网络系统的结构图，如图1所示，包括用户终端11和基站12，其中，用户终端11可以是用户设备(User Equipment，UE)，例如：可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，简称PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端侧设备，需要说明的是，在本公开实施例中并不限定用户终端11的具体类型。用户终端11可以与基站12之间进行通信，例如：用户终端11与基站12之间进行SDU传输。上述基站12可以是5G及以后版本的基站(例如：gNB、5G NR NB)，或者其他通信系统中的基站，或者称之为节点B，演进节点B，或者所述领域中其他词汇，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本公开实施例中仅以5G基站为例，但是并不限定基站12的具体类型。
请参见图2，图2是本公开实施例提供的一种系统信息的传输方法的流程图，该方法应用于用户终端，如图2所示，包括以下步骤：
步骤201、通过随机接入过程中的上行消息向基站发送系统信息请求。
其中，上述随机接入过程可以是非竞争随机接入的过程或者竞争随机接入的过程。而上述上行消息可以是随机接入过程中的任意上行消息，例如： 随机接入过程中的消息(Msg)1或者Msg3。
另外，上述系统信息请求可以是用户终端按需(on-demand)发送的系统信息请求，通过该系统信息请求可以请求基站发送用户终端需要的系统信息。
需要说明的是，本公开实施例中，随机接入过程也可以称作随机接入信道(Random Access Channel，RACH)过程。
步骤202、若所述随机接入过程成功，则不设置C-RNTI，并接收所述基站发送的所述系统信息请求对应的系统信息。
其中，上述随机接入过程成功可以是，随机接入过程完成，而随机接入过程完成也可以称作随机接入过程成功完成(Random Access procedure successfully completed)；或者，上述随机接入过程成功可以是，随机接入过程对应的竞争解决成功，例如：用户终端接收到基站发送的竞争解决消息(例如：Msg4)，用户终端通过Msg4的消息内容判断竞争解决是否成功，如Msg4的消息内容与用户终端发送的Msg3的消息内容匹配，则确定竞争解决成功。需要说明的是，本公开实施例中，对随机接入过程成功不作限定。
而上述系统信息请求对应的系统信息可以是，系统信息请求所请求的系统信息，例如：用户终端需要系统信息是系统信息13、系统信息14和系统信息20，则上述系统信息请求则是请求这些系统信息的请求，从而基站可以根据该系统信息请求发送系统信息13、系统信息14和系统信息20。
在步骤202可以是在随机接入过程成功后，不设置C-RNTI，直接接收基站发送的系统信息请求对应的系统信息。由于该系统信息是根据用户终端发送的系统信息请求发送的，从而该系统信息可以称作按需系统信息(on-demand System Information，on-demand SI)。
需要说明的是，目前通信系统中随机接入过程中用户终端会接收到基站发送的临时C-RNTI(Temporary C-RNTI)，并将该Temporary C-RNTI设置为C-RNTI的值。且目前通信系统中，当用户终端获得一个可用的C-RNTI后，用户终端会持续的进行控制信道的监听(如物理下行控制信道)，从而导致用户终端的耗电增加。而本公开实施例中，通过步骤202可以实现不设置C-RNTI，进而用户终端得不到可用的C-RNTI，从而不监听C-RNTI对应的控制信道，以节约用户终端的功耗，让用户终端更加省电。
需要说明的是，上述方法可以应用于5G系统，但对此不作限定，只要能够实现基本相同的功能，适用于其他通信系统，例如：可以应用4G或者6G系统或者其他应用系统信息的通信系统等等。
在本公开实施例中，通过随机接入过程中的上行消息向基站发送系统信息请求；若所述随机接入过程成功，则不设置C-RNTI，并接收所述基站发送的所述系统信息请求对应的系统信息。这样可以实现用户终端只接收请求的系统信息，节约用户终端功耗和系统信息的开销。另外，由于不设置C-RNTI从而用户终端不会持续进行控制信道的监听，更进一步节约用户终端的功耗。
请参见图3，图3是本公开实施例提供的另一种系统信息的传输方法的流程图，该方法应用于用户终端，如图3所示，包括以下步骤：
步骤301、接收基站发送按需系统信息(on-demand SI)指示信息。
其中，上述on-demand SI指示信息可以是哪些系统信息是需要用户终端发送请求才能发送的。通过该指示信息可以让用户终端能够准备获取到需要的系统信息。
当然，本实施例中，步骤301为可选的，例如：基站可以预先向用户终端指示需要用户终端发送请求才能发送的系统信息，或者协议中预先定义需要用户终端发送请求才能发送的系统信息等，对此本公开实施例不作限定。
步骤302、通过随机接入过程中的上行消息向基站发送系统信息请求。
作为一种可选的实施方式，上述通过随机接入过程中的上行消息向基站发送系统信息请求，包括：
通过随机接入过程中的Msg1或者Msg3向基站发送系统信息请求。
其中，上述Msg1可以是非竞争随机接入的过程中的Msg1，或者竞争随机接入的过程中的Msg1，对此本公开实施例不作限定。而上述Msg3可以是竞争随机接入的过程中的Msg3。
通过步骤301可以实现用户终端灵活地发送系统信息请求，以提高获取系统信息的灵活性。且由于通过Msg1或者Msg3向基站发送系统信息请求，这样不需要额外增加其他消息，以节约传输资源。
可选的，所述通过随机接入过程中的消息Msg1或者Msg3向基站发送系统信息请求的步骤之前，所述方法还包括：
通过无线资源控制(Radio Resource Control，RRC)实体向媒体接入控制(Media Access Control，MAC)实体发送触发随机接入过程的触发指示，其中，所述触发指示用于指示所述系统信息请求和所述系统信息请求的类型中的至少一项，所述系统信息请求的类型包括基于所述Msg1的系统信息请求或者基于所述Msg3的系统信息请求。
该实施方式中，可以实现用户终端的RRC实体指示MAC实体触发随机接入过程，以及对应的系统信息请求和所述系统信息请求的类型，从而可以实现灵活发起随机接入过程，以适应不同业务或者场景的需求，提高用户终端获取系统信息的性能。另外，该实施方式中，RRC实体可以将系统信息请求的RRC消息发送给MAC实体，这样MAC实体可以根据上述触发指示发送对应的上行消息。
可选的，所述用户终端通过的所述Msg3向所述基站发送系统信息请求；
所述通过RRC实体向MAC实体发送触发随机接入过程的触发指示的步骤之后，所述方法还包括：
根据所述触发指示，向所述基站发送随机接入过程的Msg1；
接收所述基站发送的随机接入过程的Msg2。
该实施方式中，由于Msg3是接收到基站发送的Msg2之后发送的，且Msg2是基站向用户终端发送的随机接入响应消息，这样接收到Msg2，就表示基站响应了用户终端发送随机接入请求，从而通过Msg3发送系统请求的成功率比较高。另外，Msg2可以包括上行授权信息，这样Msg3可以根据该上行授权信息向基站发送系统信息请求。
步骤303、若所述随机接入过程成功，则不设置C-RNTI，并接收所述基站发送的所述系统信息请求对应的系统信息。
作为一种可选的实施方式，所述若所述随机接入过程成功，则不设置C-RNTI，包括：
若所述随机接入过程成功，且所述随机接入过程由预设触发事件触发的，则不设置C-RNTI。
该实施方式中，随机接入过程由预设触发事件触发的，则不设置C-RNTI可以是，如果随机接入过程是因为预设触发事件触发的，则不设置C-RNTI， 如果随机接入过程不是由上述预设触发事件触发的，则可以设置C-RNTI。这样可以避免所有随机接入过程均不设置C-RNTI导致的用户终端无法接收到基站发送的控制消息的问题，以提高用户终端整体性能。
其中，上述预设触发事件触发可以是用户终端预先设置好的，或者协议预先定义的，或者基站配置给用户终端，或者用户设置的等。
优选的，所述预设触发事件包括：系统信息请求事件，这样可以实现若随机接入过程由系统信息请求事件触发的，则不设置C-RNTI，反之，则可以设置C-RNTI。
其中，所述系统信息请求事件可以包括：
基于随机接入过程中的Msg1的系统信息请求事件或者基于随机接入过程中的Msg3的系统信息请求事件。
需要于说明的是，本实施例中，对上述预设触发事件不作限定，例如：上述预设触发事件还可以是获取特定的系统信息的事件，例如：获取目标系统信息的事件，该目标系统信息可以是预先设定的，例如：SI13、SI14、或者SI20等等。
作为一种可选的实施方式，所述随机接入过程中的下行消息中包括Temporary C-RNTI；
所述若所述随机接入过程成功，则不设置C-RNTI，包括：
若所述随机接入过程成功，则不设置C-RNTI，并丢弃所述Temporary C-RNTI。
其中，上述下行消息可以是随机接入过程中的Msg2，但对此不作限定，例如：还可以是Msg4或者其他下行消息。
该实施方式中，可以实现不设置C-RNTI，并丢弃所述Temporary C-RNTI，从而可以避免用户终端获得C-RNTI，这样用户终端不监听C-RNTI对应的控制信道，从而可以让用户终端更加省电。
可选的，所述下行消息为所述随机接入过程中的Msg2；
所述若所述随机接入过程成功，则不设置C-RNTI，并丢弃所述Temporary C-RNTI，包括：
若竞争解决成功，则不设置C-RNTI，并丢弃所述Temporary C-RNTI。
其中，上述竞争解决成功可以理解为随机接入过程成功，例如：用户终端可以是在启动竞争解决定时器(如mac-Contention Resolution Timer)有效时间内，接收到的竞争解决消息(Msg4)，之后用户终端可以判断竞争解决是否成功，如果成功，则不设置C-RNTI，并丢弃所述Temporary C-RNTI。
该实施方式中，可以实现通过Msg2发送Temporary C-RNTI，用户终端在竞争解决成功后，不设置C-RNTI，并丢弃所述Temporary C-RNTI，从而可以避免用户终端获得C-RNTI，这样用户终端不监听C-RNTI对应的控制信道，从而可以让用户终端更加省电。
本实施例，在图2所示的实施例的基础上增加了多种可选的实施方式，且相比图2所示的实施例中，本实施例可以更进一步节约用户终端功耗，还可以实现提高用户终端获取系统信息的成功率等有益效果。
请参见图4，图4是本公开实施例提供的另一种系统信息的传输方法的示意图，如图4所示，包括以下步骤：
步骤401、基站发送按需系统信息(on-demand SI)指示信息，该指示信息可以指示哪些系统信息是需要用户终端发送请求信息才能发送。
步骤402、用户终端的RRC实体触发基于Msg3的SI请求，并生成该SI请求对应的RRC消息。用户终端的RRC实体将该SI请求的RRC消息发送给MAC层。
其中，用户终端的RRC实体指示MAC实体触发RACH过程，并指示触发该RACH过程的相关信息可以包括以下一项或多项的任意组合：
系统信息请求和系统信息请求的类型；
其中，系统信息请求的类型可以包括以下一项或多项的任意组合：
基于Msg1的系统信息请求和基于Msg3的系统信息请求；
用户终端的MAC实体根据RRC实体的指示信息触发RACH过程发送Msg1。
步骤403、基站发送Msg2信息给用户终端。
步骤404、用户终端根据Msg2中的上行授权信息发送该系统信息请求(System Information Request)给基站，通过Msg3发送。
步骤405、基站发送Msg4信息给用户终端。
用户终端在接收到该Msg4信息后，如果竞争解决成功，用户终端在满足以下条件后不设置C-RNTI(否则设置C-RNTI取值)：
用户终端不设置C-RNTI的取值，如果该RACH过程是由以下事件触发的，该触发事件包括以下至少一种：
系统信息请求、基于Msg1的系统信息请求和基于Msg3的系统信息请求；
如果用户终端没有设置C-RNTI的取值，用户终端丢弃Temporary C-RNTI。
步骤406、基站在接收到用户终端的系统信息请求信息后，发送用户终端请求的系统信息给用户终端。其中，传输系统信息的传输消息可以包括：系统信息(System Information)、系统信息响应(system information response)和RRC连接配置(RRC Connection Reconfiguration)中的至少一项。
在上述步骤中，用户终端可以在Msg3的系统信息请求过程中可以通过避免获得C-RNTI，从而不监听C-RNTI对应的控制信道，从而可以让用户终端更加省电。
请参见图5，图5是本公开实施例提供的一种用户终端的结构图，如图5所示，用户终端500包括：
第一发送模块501，用于通过随机接入过程中的上行消息向基站发送系统信息请求；

存储器809可用于存储软件程序以及各种数据。存储器809可主要包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)等；存储数据区可存储根据手机的使用所创建的数据(比如音频数据、电话本等)等。此外，存储器809可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。
处理器810是用户终端的控制中心，利用各种接口和线路连接整个用户终端的各个部分，通过运行或执行存储在存储器809内的软件程序和/或模块，以及调用存储在存储器809内的数据，执行用户终端的各种功能和处理数据，从而对用户终端进行整体监控。处理器810可包括一个或多个处理单元；可选的，处理器810可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器810中。
用户终端800还可以包括给各个部件供电的电源811(比如电池)，可选的，电源811可以通过电源管理系统与处理器810逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。
另外，用户终端800包括一些未示出的功能模块，在此不再赘述。

本公开实施例还提供一种计算机可读存储介质，计算机可读存储介质上存储有计算机程序，该计算机程序被处理器执行时实现上述系统信息的传输方法实施例的各个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。其中，所述的计算机可读存储介质，如只读存储器(Read-Only Memory，简称ROM)、随机存取存储器(Random Access Memory，简称RAM)、磁碟或者光盘等。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本公开的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端(可以是手机，计算机，服务器，空调器，或者网络设备等)执行本公开各个实施例所述的方法。
