相关申请的交叉引用
本申请主张在2019年8月20日在中国提交的中国专利申请号No.201910769165.8的优先权,其全部内容通过引用包含于此。
本公开涉及通信技术领域,尤其涉及一种寻呼方法、装置、设备及计算机可读存储介质。
在多轮寻呼方法中,为减少空口寻呼信令,寻呼的触发网元可以采用两轮寻呼方式。在第一轮寻呼中,寻呼的触发网元根据终端曾经接入哪些小区,确定一个推荐的寻呼小区列表,然后通知所有控制着该列表中的至少一个小区的无线接入网节点需要寻呼该终端,并且分别告知这些无线接入网节点哪些它们所控制的小区是推荐执行寻呼的。如果这一轮寻呼没有响应,寻呼的触发网元会触发第二轮寻呼,以要求该终端的可达性区域(例如注册区域、基于无线接入网的通知区域RNA(RAN-based Notification Area,接入网通知区域)等)范围内的所有小区执行寻呼。
为了实现全球无线接入覆盖,业界提出了NTN(Non-Terrestrial Network,非地面网络)架构。非地面网络是指将至少一部分无线接入网网元放入非地面载体(例如低轨卫星)之中,称为非地面载荷。终端将与非地面载荷连接,而非地面载荷再与固定于地面的网元连接。
在非地面网络系统中,小区的覆盖范围可能是快速变化的。例如,在近地轨道组网的卫星通信系统中,小区的覆盖通常会以每秒数公里的速度快速移动,终端一旦与网络断开连接,所驻留的小区也会快速变化,并且绝大多数情况下终端所驻留的小区都不是先前曾经接入的小区。如果网络仍旧采用了传统的多轮寻呼方法,在终端曾经接入的小区上寻呼该终端,将会寻呼失败。

在收到了第一信息之后,第二网元即可根据该第一信息执行寻呼相关的处理。例如,确定需执行寻呼的小区等等。
在本公开实施例中,第一网元向第二网元发送第一信息,所述第一信息为最新的、终端与所述无线通信系统连接时的地理位置信息,因此,第二网元在对终端进行寻呼时,可以此第一信息为依据,从而提高了寻呼的成功率。
在上述实施例的基础上,为进一步提高寻呼的成功率,所述方法还可包 括:针对所述第二网元控制的至少一个小区,根据所述第一信息,确定是否在目标小区中执行寻呼,其中,所述目标小区为所述至少一个小区中的任意小区。
具体的,在本公开实施例中可通过以下至少两种方法来确定是否在目标小区中执行寻呼。
方法一,在所述目标小区的覆盖范围包括第二位置点的情况下,确定在所述目标小区中执行寻呼,其中,所述第二位置点为所述第一信息所指示的位置点。也就是说,在这种情况下,在第一信息所指示的位置点在所述目标小区的覆盖范围内的情况下,在目标小区中执行寻呼;否则不执行寻呼。
方法二,在所述目标小区的覆盖范围内确定第一位置点,其中,所述第一位置点是所述目标小区的覆盖范围内和第二位置点之间的距离最近的一点,所述第二位置点为所述第一信息所指示的位置点;在所述第一位置点和所述第二位置点之间的距离小于或等于第一预设值的情况下,确定在所述目标小区中执行寻呼。其中,该第一预设值可任意设置。
当然,在本公开实施例中,确定是否在目标小区中执行寻呼的方法可不局限于以上两种。
参见图3,图3是本公开实施例提供的寻呼方法的流程图,应用于无线通信系统中的第三网元(如,gNB),如图3所示,包括以下步骤:
步骤301、向第一网元发送第二消息,在所述第二消息中包括第一信息;所述第一信息为最新的、终端与所述无线通信系统连接时的地理位置信息。
可选的,所述第一信息包括所述终端的经纬度坐标信息;或者,所述第一信息包括位置确定辅助信息,所述位置确定辅助信息用于确定所述终端的经纬度坐标信息。其中,所述第一信息的解释可参见前述实施例的相关描述。
在本公开实施例中,所述第一信息为最新的、终端与所述无线通信系统连接时的地理位置信息,因此,第一网元向第二网元发送第一信息后,第二网元在对终端进行寻呼时,可以此第一信息为依据,从而提高了寻呼的成功率。
在典型的低轨卫星组网的非地面网络中,小区均以每秒数公里的速度快速移动。这使得终端与网络断开连接一段时间以后,所驻留的小区往往不是 先前处于连接态时所连接的小区。这样一来,网络利用记录终端所连接的小区来执行多轮寻呼的优化方案就失去了意义。在小区覆盖情况快速变化的场景中,基于终端历史连接信息的多轮寻呼不再适用。
因此,在本公开实施例中的寻呼方法,用以解决在非地面网络中多轮寻呼的第一轮寻呼失败的问题。在本公开实施例中,寻呼的触发网元告知寻呼的执行网元终端上一次接入网络时的地理位置信息或者能够确定地理位置信息的位置确定辅助信息,以辅助多轮寻呼。以下,结合不同的实施例详细描述一下本公开实施例的实现方案。
参见图4,图4是本公开实施例提供的寻呼方法的流程图。在图4中,终端在进入RRC空闲态时,RAN(Radio Access Network,无线接入网络)节点向核心网网元上报地理位置信息。
如图4所示,包括以下步骤:
步骤401、终端处于CM(Connection Management,连接管理)连接态。
步骤402、核心网网元(以AMF为例)决定将终端移入CM空闲态,因此向旧RAN(Radio Access Network,无线接入网络)节点(以旧gNB为例)发送了一条消息以指示这一决定(以N2UE(User Equipment,用户设备)上下文释放命令消息为例)。
步骤403、旧RAN节点向核心网网元发送了一条反馈消息(以N2UE上下文释放完成消息为例),其中包含该旧RAN节点所掌握的最新的终端的地理位置信息。所述终端的地理位置信息可以是终端所处位置的经纬度坐标,或为能够推算出上述经纬度坐标的等价参数,例如其在地心坐标系之中的三维位置矢量。
其中,所述最新的终端的地理位置信息,指的是最新的、所述终端与无线通信系统连接时的地理位置信息。
步骤404、可选地,旧RAN节点指示终端进入CM空闲态。
步骤405、在某一时刻,核心网网元收到了下行业务,并因此触发寻呼。
步骤406、核心网网元决定采用两步寻呼的方法,并启动了一个定时器。
步骤407、核心网网元选择向一部分新RAN节点发送寻呼消息(以N2寻呼消息为例)。核心网网元所发送的寻呼消息中包含它在第403步中所接收 的地理位置信息。这些新RAN节点可以包含前文所述的旧RAN节点,也可以不包含。
步骤408、接收到步骤407中所述的寻呼消息的每个新RAN节点,针对它所管辖的每个小区,判决该小区是否需要在空口执行寻呼。具体的,新RAN节点根据上述地理位置信息与星历推算需要执行空口寻呼的小区。具体判决方式在后续实施例中详细描述。
步骤409、在判决需要执行寻呼的小区执行寻呼。
步骤410、如果终端接收到了第409步的寻呼消息,它将与网络交互以进入连接态。
步骤411、在步骤410的条件下,核心网网元停止步骤406中所启动的定时器。相对地,如果步骤410直至计时器超时也依旧未出现(亦即核心网网元没有收到终端的响应),核心网网元将触发第二轮寻呼。
参见图5,图5是本公开实施例提供的寻呼方法的流程图。在图5中,终端在RRC连接态中,RAN节点向核心网网元上报地理位置信息。
如图5所示,包括以下步骤:
步骤501、终端处于CM连接态。
步骤502、旧RAN节点(以旧gNB为例)向核心网网元(以AMF为例)发送了一条接口消息,其中包含旧RAN节点所掌握的最新的终端的地理位置信息。所述终端的地理位置信息可以是终端所处位置的经纬度坐标,或为能够推算出上述经纬度坐标的等价参数,例如其在地心坐标系之中的三维位置矢量。
其中,所述最新的终端的地理位置信息,指的是最新的、所述终端与无线通信系统连接时的地理位置信息。
步骤503、可选地,旧RAN节点指示终端进入CM空闲态。
步骤504、在某一时刻,核心网网元收到了下行业务,并因此触发寻呼。
步骤505、核心网网元决定采用两步寻呼的方法,并启动了一个定时器。
步骤506、核心网网元选择指示一部分新RAN节点进行寻呼,向这些新RAN节点发送一条寻呼消息(以N2寻呼消息为例)。核心网网元所发送的寻呼消息中包含它在第502步所接收的地理位置信息。这些新RAN节点可以包 含前文所述的旧RAN节点,也可以不包含。
步骤507、接收到步骤506中所述的寻呼消息的每个新RAN节点针对它所管辖的每个小区,判决该小区是否需要在空口执行寻呼。具体的,新RAN节点根据上述地理位置信息与星历推算需要执行空口寻呼的小区。具体判决方式在后续实施例中详细描述。
步骤508、在判决需要执行寻呼的小区执行寻呼。
步骤509、如果终端接收到了第508步的寻呼消息,它将与网络交互以进入连接态。
步骤510、在步骤509的条件下,核心网网元停止步骤505中所启动的定时器。相对地,如果步骤509直至计时器超时也依旧未出现(亦即核心网网元没有收到终端的响应),核心网网元将触发第二轮寻呼。
参见图6,图6是本公开实施例提供的寻呼方法的流程图。在图6中,终端在RRC连接态中,RAN节点向核心网网元上报地理位置信息。
如图6所示,包括以下步骤:
步骤601、旧RAN节点(以gNB为例)指示终端进入RRC非活跃态。
步骤602、在某一时刻,旧RAN节点收到了下行业务,并因此触发寻呼。
步骤603、旧RAN节点决定采用两步寻呼的方法,并启动了一个定时器。
步骤604、旧RAN节点选择向一部分新RAN节点发送寻呼消息(以XnAP(Xn Application Protocol,Xn应用流程协议)RAN寻呼消息为例)。旧RAN节点所发送的寻呼消息中,包含旧RAN节点所掌握的最新的终端的地理位置信息。所述终端的地理位置信息可以是终端所处位置的经纬度坐标,或为能够推算出上述经纬度坐标的等价参数,例如其在地心坐标系之中的三维位置矢量。
其中,所述最新的终端的地理位置信息,指的是最新的、所述终端与无线通信系统连接时的地理位置信息。
步骤605、接收到步骤604中所述的寻呼消息的每个新RAN节点针对它所管辖的每个小区,判决该小区是否需要在空口执行寻呼。具体的,新RAN节点根据上述地理位置信息与星历推算需要执行空口寻呼的小区。具体判决方式在后续实施例中详细描述。
步骤606、在判决需要执行寻呼的小区执行寻呼。
步骤607、如果终端接收到了第606步的寻呼消息,它将与网络交互以进入连接态。
步骤608、在步骤607的条件下,旧RAN节点停止步骤603中所启动的定时器。相对地,如果步骤607直至计时器超时也依旧未出现(亦即旧RAN节点没有收到终端的响应),旧RAN节点将按照相关技术触发第二轮寻呼。
以下结合图7和图8描述一下在图4-图6的实施例中的寻呼判决方式。
在一个实施例中,新RAN节点在接收到包含地理位置信息的寻呼消息之后,仅在当前能够覆盖该地理位置的小区执行寻呼。
具体的,在图4-图6的实施例中,所述的新RAN节点在接收到包含终端的地理位置信息的寻呼消息之后,针对其所控制的每一个小区,判断该小区当前是否覆盖地理位置信息所指示的地理位置。如果能够覆盖,则在该小区上执行寻呼,否则不执行寻呼。
例如,如图7所示,小区覆盖范围为A,地理位置信息所表示的点为点B,点B在范围A内,那么,可确定在该小区内执行寻呼。
在一个实施例中,新RAN节点在接收到包含地理位置信息的寻呼消息之后,仅在覆盖范围与该地理位置之间的最短距离小于或等于某个阈值的小区执行寻呼。
具体的,在图4-图6的实施例中,所述的新RAN节点在接收到包含终端的地理位置信息的寻呼消息之后,针对其所控制的每一个小区,对于其中的任意的目标小区,判断该目标小区当前的覆盖范围与该地理位置之间的最短距离是否小于上述阈值。如果条件满足,则在该目标小区上执行寻呼,否则不执行寻呼。
例如,如图8所示,小区覆盖范围为A,地理位置信息所表示的点为点B。在覆盖范围内确定点C,其中,点C为覆盖范围A内到点B距离最近的点。那么,当点B和点C之间的距离小于某个预设值时,可确定在该小区内执行寻呼。
由以上可以看出,寻呼的触发网元在触发第一轮寻呼时,可以告知寻呼的执行节点终端先前接入网络时的地理位置,使得寻呼的执行节点可以据此 执行第一轮寻呼,避免了传统多轮寻呼方法在非地面网络中第一轮寻呼经常失败的问题。
