下面结合附图对本公开所提供的定位系统信息的获取方法及其装置进行详细地介绍。
图2为本公开实施例提供的一种定位系统信息的获取方法的流程图，该方法由终端设备执行。本实施例中的定位系统信息的获取方法可以应用在终端设备中，例如手机或者具备移动通信功能的平板、智能手表等，对此不做限制。如图2所示，该方法可以包括但不限于如下步骤：
S21，响应于终端设备未处于连接态，且满足获取定位系统信息的预设条件，终端设备进入连接态，并获取定位系统信息。
本公开实施例中，终端设备未处于连接态可以为终端设备处于空闲态，或者处于非激活态，或者还可以为终端设备处于其他未与网络侧设备连接的状态，本公开实施例对此不作具体限制。
在一种可能的实现方式中，终端设备未处于连接态，为终端设备处于空闲态的情况下，本公开实施 例中，终端设备处于空闲态，且满足获取定位系统信息的预设条件的情况下，终端设备进入连接态，并获取定位系统信息，从而终端设备可以根据定位系统信息进行定位，以避免定位错误。
在另一种可能的实现方式中，终端设备未处于连接态，为终端设备处于非激活态的情况下，本公开实施例中，终端设备处于非激活态，且满足获取定位系统信息的预设条件的情况下，终端设备进入连接态，并获取定位系统信息，从而终端设备可以根据定位系统信息进行定位，以避免定位错误。
在一些实施例中，获取定位系统信息的预设条件，包括以下至少一种：
确定定位系统信息发生更改；
接收到高层信令，高层信令用于指示获取定位系统信息。
本公开实施例中，高层信令为RRC(Radio Resource Control，无线资源控制)或MAC CE(mediaaccess control control element，媒体接入控制控制元素)等。
本公开实施例中，获取定位系统信息的预设条件可以为确定定位系统信息发生更改，其中，终端设备确定确定定位系统信息发生更改，可能接收到网络侧设备的指示定位系统信息发生更改的指示信息，或者定时器超时等。
本公开实施例中，获取定位系统信息的预设条件可以为接收到高层信令，高层信令用于指示获取定位系统信息。
本公开实施例中，获取定位系统信息的预设条件可以为确定定位系统信息发生更改和接收到高层信令，高层信令用于指示获取定位系统信息。
在一种可能的实现方式中，在获取定位系统信息的预设条件为确定定位系统信息发生更改的情况下，本公开实施例中，终端设备未处于连接态，且满足确定定位系统信息发生更改的情况下，终端设备进入连接态，并获取定位系统信息。从而终端设备可以根据定位系统信息进行定位，以避免定位错误。
在另一种可能的实现方式中，在获取定位系统信息的预设条件为接收到高层信令，高层信令用于指示获取定位系统信息的情况下，本公开实施例中，终端设备未处于连接态，且满足接收到高层信令，高层信令用于指示获取定位系统信息的情况下，终端设备进入连接态，并获取定位系统信息。从而终端设备可以根据定位系统信息进行定位，以避免定位错误。
在又一种可能的实现方式中，在获取定位系统信息的预设条件为确定定位系统信息发生更改和接收到高层信令，高层信令用于指示获取定位系统信息的情况下，本公开实施例中，终端设备未处于连接态，且满足确定定位系统信息发生更改和接收到高层信令，高层信令用于指示获取定位系统信息的情况下，终端设备进入连接态，并获取定位系统信息。从而终端设备可以根据定位系统信息进行定位，以避免定位错误。
可以理解的是，终端设备确定满足获取定位系统信息的预设条件，当获取定位系统信息的预设条件为接收到定位系统信息发生更改的指示信息的情况下，终端设备确定满足接收到定位系统信息发生更改的指示信息，可以通过获取网络侧设备发送的更新指示消息，其中，更新指示消息用于指示接收到定位系统信息发生更改的指示信息，在终端设备接收到网络侧设备发送的更新指示信息的情况下，终端设备可以确定满足接收到定位系统信息发生更改的指示信息。其中，网络侧设备向终端设备发送更新指示消息可以通过广播的方式进行发送。
本公开实施例中，终端设备进入连接态，获取定位系统信息，可以向网络侧设备发送系统信息请求消息，以请求网络侧设备配置定位系统信息，
其中，定位系统信息可以包括MIB(master information block，主信息块)和/或SIB(system information block，系统信息块)。MIB可以包括终端设备接入小区所需的必要的信息，例如：定位系统帧号、子载波间隔等。SIB可以包括SIB1和其他SIB，其中，其他SIB包括SIB2、SIB3、SIB4等。SIB1可以包括其他SIB的调度信息、接入控制信息和小区选择信息等，其他SIB可以包括其他功能所需的参数，例如，小区重选、定位、紧急通知、侧链路sidelink等。
可以理解的是，终端设备处于连接态，可以很好的接收网络侧设备发送的信息，从而，在满足获取定位系统信息的预设条件的情况下，终端设备进入连接态，可以向网络侧设备发起请求，并接收网络侧设备发送的相关信息，获取定位系统信息，从而，终端设备可以根据定位系统信息进行定位，能够避免定位错误。
本公开实施例中，终端设备可以为远端终端设备，或者也可以为中继终端设备。
为了支持终端设备与终端设备之间的直接通信，引入了侧链路sidelink通信方式，终端设备与终端设备可以通过接口PC-5交互信息。根据发送和接收终端设备的对应关系，在sidelink上支持三种传输方式，单播，组播和广播。
其中，在终端设备为远端终端设备的情况下，远端终端设备可以不直接与网络侧设备连接而通过另外一个作为中继终端设备的终端设备与网络侧设备进行通信。
在一种可能的实现方式中，终端设备为中继终端设备，本公开实施例中，中继终端设备未处于连接态，且满足获取定位系统信息的预设条件的情况下，中继终端设备进入连接态，并获取定位系统信息，从而中继终端设备可以根据定位系统信息进行定位，以避免定位错误。
在另一种可能的实现方式中，终端设备为远端终端设备，本公开实施例中，远端终端设备未处于连接态，且满足获取定位系统信息的预设条件的情况下，远端终端设备可以进入连接态，并获取定位系统信息，从而远端终端设备可以根据定位系统信息进行定位，以避免定位错误。
本公开实施例中，当远端终端设备未处于连接态，例如：处于空闲态和/或非激活态时，如果缺少定位系统信息，远端终端设备可以向中继终端设备发送sidelinkRRC消息(RemoteUEInformationSidelink)，其中携带系统信息请求，中继终端设备收到系统信息请求之后获取对应的定位系统信息，然后通过sidelinkRRC消息(UuMessageTransferSidelink)将定位系统信息发送给定位系统信息。
但是，中继终端设备接收到远端终端设备发送的系统信息请求之后，获取对应的定位系统信息，可以是中继终端中之前存储的定位系统信息，或者中继终端设备进一步通过接收网络侧设备广播信息获取的定位系统信息，或者通过其他方式获取的定位系统信息，将定位系统信息发送至远端终端设备。
而远端终端设备接收中继终端设备发送的定位系统信息，无法确定中继终端设备获取定位系统信息时间，若远端终端设备根据自己接收到的定位系统信息的时间来定位，可能会导致定位错误。
由此可见，远端终端设备虽然可以通过向中继终端设备发送sidelinkRRC消息，发送系统信息请求，接收中继终端设备发送的sidelinkRRC消息获取定位系统信息，但是，由于无法确定中继终端设备获取定位系统信息时间，如果按照接收到定位系统信息的时间进行定位，可能会导致定位错误。
基于此，本公开实施例提供一种定位系统信息的获取方法，远端终端设备未处于连接态，且满足获取定位系统信息的预设条件，远端终端设备进入连接态，获取定位系统信息。
其中，远端终端设备进入连接态，获取定位系统信息，可以通过向网络侧设备发送系统信息请求消息，系统信息请求消息用于指示远端终端设备需要获取的定位系统信息，从而网络侧设备接收到远端终 端设备发送的系统信息请求消息后，可以向远端终端设备发送远端终端设备所请求的定位系统信息。由此，终端设备接收到定位系统信息，并根据接收定位系统信息的时间进行定位，能够避免定位失败。
需要说明的是，远端终端设备进入连接态，向网络侧设备发送系统信息请求消息，以及网络侧设备向远端终端设备发送远端终端设备所请求的定位系统信息，可以通过中继终端设备转发，中继终端设备在这个过程中只是起到中转作用，远端终端设备接收到定位系统信息的时间与中继终端设备接收到定位系统信息的时间时延较小，由此，远端终端设备可以根据接收待定位系统信息的时间进行定位，能够避免定位错误。
在一些实施例中，网络侧设备向远端终端设备发送的定位系统信息包括GNSS(global navigation satellite system，全球导航卫星系统)时间。
本公开实施例中，远端终端设备进入连接态，向网络侧设备发送系统信息请求消息，接收网络侧设备发送的定位系统信息，定位系统信息包括GNSS时间，由此，远端终端设备接收到网络侧设备发送的定位系统信息，确定网络侧设备发送定位系统信息的GNSS时间，可以预估中继终端设备转发的时延，在GNSS时间的基础上，考虑中继终端设备转发的时延，远端终端设备可以确定中继终端设备接收到定位系统信息的时间，从而，远端终端设备可以根据中继终端设备接收到定位系统信息的时间进行定位，能够避免定位错误。
本公开实施例中，响应于终端设备未处于连接态，且满足获取定位系统信息的预设条件，终端设备进入连接态，并获取定位系统信息。
其中，终端设备获取定位系统信息可以通过向网络侧设备发送系统信息请求消息，系统信息请求消息用于指示终端设备需要获取的定位系统信息，从而网络侧设备接收到终端设备发送的系统信息请求消息，可以向终端设备发送终端设备所请求的定位系统信息。
其中，网络侧设备向终端设备发送定位系统信息，可以向终端设备发送无线资源控制RRC重配信息，其中，RRC重配信息包括定位系统信息。
本公开实施例中，终端设备向网络侧设备发送系统信息请求消息，可以在确定接收到网络侧设备发送的配置信息的情况下，向网络侧设备发送系统信息请求消息。其中，配置信息可以包括禁止定时器时长。
其中，配置信息可以为按需请求系统信息配置(onDemandSIB-Request)，按需请求系统信息配置包括禁止定时器时长。
本公开实施例中，终端设备在向网络侧设备发送系统信息请求消息之后，可以启动禁止定时器，其中，在禁止定时器运行期间，停止向网络侧设备发送系统信息请求消息。可以理解的是，禁止定时器可以在禁止定时器时长内正常运行。
本公开实施例中，终端设备在接收网络侧设备发送的无线资源控制RRC重配信息之后，可以停止禁止定时器的运行。其中，终端设备可以在禁止定时器的运行未超出禁止定时器时长的情况下，若接收到网络侧设备发送的无线资源控制RRC重配信息，停止禁止定时器的运行。
通过实施本公开实施例，响应于终端设备未处于连接态，且满足获取定位系统信息的预设条件，终端设备进入连接态，并获取定位系统信息。由此，终端设备可以根据定位系统信息进行定位，能够避免定位错误。

在一些实施例中，网络侧设备向远端终端设备发送的定位系统信息包括GNSS时间。
可以理解的是，远端终端设备进入连接态，向网络侧设备发送系统信息请求消息，接收网络侧设备发送的定位系统信息，定位系统信息包括GNSS时间，由此，远端终端设备接收到网络侧设备发送的定位系统信息，确定网络侧设备发送定位系统信息的GNSS时间，可以预估中继终端设备转发的时延，在GNSS时间的基础上，考虑中继终端设备转发的时延，远端终端设备可以确定中继终端设备接收到定位系统信息的时间，从而，远端终端设备可以根据中继终端设备接收到定位系统信息的时间进行定位，能够避免定位错误。

本公开实施例中，获取定位系统信息的预设条件可以为确定定位系统信息发生更改和接收到高层信令，高层信令用于指示获取定位系统信息。
在一种可能的实现方式中，在获取定位系统信息的预设条件为确定定位系统信息发生更改的情况下，本公开实施例中，终端设备未处于连接态，且满足确定定位系统信息发生更改的情况下，终端设备进入连接态，向网络侧设备发送系统信息请求消息。
在另一种可能的实现方式中，在获取定位系统信息的预设条件为接收到高层信令，高层信令用于指示获取定位系统信息的情况下，本公开实施例中，终端设备未处于连接态，且满足接收到高层信令，高层信令用于指示获取定位系统信息的情况下，终端设备进入连接态，向网络侧设备发送系统信息请求消息。
在又一种可能的实现方式中，在获取定位系统信息的预设条件为确定定位系统信息发生更改或接收到高层信令，高层信令用于指示获取定位系统信息的情况下，本公开实施例中，终端设备未处于连接态，且满足确定定位系统信息发生更改和接收到高层信令，高层信令用于指示获取定位系统信息的情况下，终端设备进入连接态，向网络侧设备发送系统信息请求消息。
可以理解的是，终端设备确定满足获取定位系统信息的预设条件，当获取定位系统信息的预设条件为接收到定位系统信息发生更改的指示信息的情况下，终端设备确定满足接收到定位系统信息发生更改的指示信息，可以通过获取网络侧设备发送的更新指示消息，其中，更新指示消息用于指示接收到定位系统信息发生更改的指示信息，在终端设备接收到网络侧设备发送的更新指示信息的情况下，终端设备 可以确定满足接收到定位系统信息发生更改的指示信息。其中，网络侧设备向终端设备发送更新指示消息可以通过广播的方式进行发送。
本公开实施例中，终端设备进入连接态，获取定位系统信息，可以向网络侧设备发送系统信息请求消息，以请求网络侧设备配置定位系统信息，
其中，定位系统信息可以包括MIB(master information block，主信息块)和/或SIB(system information block，系统信息块)。MIB可以包括终端设备接入小区所需的必要的信息，例如：定位系统帧号、子载波间隔等。SIB可以包括SIB1和其他SIB，其中，其他SIB包括SIB2、SIB3、SIB4等。SIB1可以包括其他SIB的调度信息、接入控制信息和小区选择信息等，其他SIB可以包括其他功能所需的参数，例如，小区重选、定位、紧急通知、侧链路sidelink等。终端设备可以根据需要选择定位系统信息中的信息进行读取。
本公开实施例中，终端设备可以为远端终端设备，或者也可以为中继终端设备。
为了支持终端设备与终端设备之间的直接通信，引入了侧链路sidelink通信方式，终端设备与终端设备可以通过接口PC-5交互信息。根据发送和接收终端设备的对应关系，在sidelink上支持三种传输方式，单播，组播和广播。
其中，在终端设备为远端终端设备的情况下，远端终端设备可以不直接与网络侧设备连接而通过另外一个作为中继终端设备的终端设备与网络侧设备进行通信。
在一种可能的实现方式中，终端设备为中继终端设备，本公开实施例中，中继终端设备未处于连接态，且满足获取定位系统信息的预设条件的情况下，中继终端设备进入连接态，向网络侧设备发送系统信息请求消息，系统信息请求消息用于指示请求的定位系统信息，以获取定位系统信息。从而中继终端设备可以根据定位系统信息进行定位，以避免定位错误。
在另一种可能的实现方式中，终端设备为远端终端设备，本公开实施例中，远端终端设备未处于连接态，且满足获取定位系统信息的预设条件的情况下，远端终端设备进入连接态，向网络侧设备发送系统信息请求消息，系统信息请求消息用于指示请求的定位系统信息，以获取定位系统信息，从而远端终端设备可以根据定位系统信息进行定位，以避免定位错误。
本公开实施例中，当远端终端设备未处于连接态，例如：处于空闲态和/或非激活态时，如果缺少定位系统信息，远端终端设备可以向中继终端设备发送sidelinkRRC消息(RemoteUEInformationSidelink)，其中携带系统信息请求，中继终端设备收到系统信息请求之后获取对应的定位系统信息，然后通过sidelinkRRC消息(UuMessageTransferSidelink)将定位系统信息发送给定位系统信息。
但是，中继终端设备接收到远端终端设备发送的系统信息请求之后，获取对应的定位系统信息，可以是中继终端中之前存储的定位系统信息，或者中继终端设备进一步通过接收网络侧设备广播信息获取的定位系统信息，或者通过其他方式获取的定位系统信息，将定位系统信息发送至远端终端设备。
而远端终端设备接收中继终端设备发送的定位系统信息，无法确定中继终端设备获取定位系统信息时间，若远端终端设备根据自己接收到的定位系统信息的时间来定位，可能会导致定位错误。
由此可见，远端终端设备虽然可以通过向中继终端设备发送sidelinkRRC消息，发送系统信息请求，接收中继终端设备发送的sidelinkRRC消息获取定位系统信息，但是，由于无法确定中继终端设备获取定位系统信息时间，如果按照接收到定位系统信息的时间进行定位，可能会导致定位错误。
基于此，本公开实施例提供一种定位系统信息的获取方法，远端终端设备未处于连接态，且满足获 取定位系统信息的预设条件，远端终端设备进入连接态，获取定位系统信息。
其中，远端终端设备进入连接态，获取定位系统信息，可以通过向网络侧设备发送系统信息请求消息，系统信息请求消息用于指示远端终端设备需要获取的定位系统信息，从而网络侧设备接收到远端终端设备发送的系统信息请求消息后，可以向远端终端设备发送远端终端设备所请求的定位系统信息。由此，终端设备接收到定位系统信息，并根据接收定位系统信息的时间进行定位，能够避免定位失败。
需要说明的是，远端终端设备进入连接态，向网络侧设备发送系统信息请求消息，以及网络侧设备向远端终端设备发送远端终端设备所请求的定位系统信息，可以通过中继终端设备转发，中继终端设备在这个过程中只是起到中转作用，远端终端设备接收到定位系统信息的时间与中继终端设备接收到定位系统信息的时间时延较小，由此，远端终端设备可以根据接收待定位系统信息的时间进行定位，能够避免定位错误。
在一些实施例中，网络侧设备向远端终端设备发送的定位系统信息包括GNSS(global navigation satellite system，全球导航卫星系统)时间。
本公开实施例中，远端终端设备进入连接态，向网络侧设备发送系统信息请求消息，接收网络侧设备发送的定位系统信息，定位系统信息包括GNSS时间，由此，远端终端设备接收到网络侧设备发送的定位系统信息，确定网络侧设备发送定位系统信息的GNSS时间，可以预估中继终端设备转发的时延，在GNSS时间的基础上，考虑中继终端设备转发的时延，远端终端设备可以确定中继终端设备接收到定位系统信息的时间，从而，远端终端设备可以根据中继终端设备接收到定位系统信息的时间进行定位，能够避免定位错误。
本公开实施例中，终端设备未处于连接态，且满足获取定位系统信息的预设条件的情况下，终端设备进入连接态，获取定位系统信息。
其中，终端设备获取定位系统信息可以通过向网络侧设备发送系统信息请求消息，系统信息请求消息用于指示终端设备需要获取的定位系统信息，从而网络侧设备接收到终端设备发送的系统信息请求消息，可以确定终端设备所请求的定位系统信息。
基于此，网络侧设备在确定终端设备所请求的定位系统信息的情况下，可以向处于连接态的终端设备发送定位系统信息，由此，终端设备可以根据定位系统信息进行定位，能够避免定位错误。

本公开实施例中，终端设备向网络侧设备发送系统信息请求消息，可以在确定接收到网络侧设备发送的配置信息的情况下，向网络侧设备发送系统信息请求消息。其中，配置信息可以包括禁止定时器时长。
