具体实施方式
在3GPP关于NTN,Non-Terrestrial Networks的部分,针对由空间通信节点运动触发频繁的TAU的问题,采用了“固定跟踪区域”的解决方案,即,TAC固定在地面上,而空间通信节点小区在地面上随着空间通信的移动而改变。也就是说,空间通信节点在地面扫描,当到达下一个计划的地球固定跟踪区域时,空间通信节点小区广播的TAC发生变化。“固定跟踪区域”的解决方案虽然解决了空间通信节点运动触发频繁的TAU的问题,但是也对小区的系统消息更新或者寻呼带来了新的问题。比如,由于空间通信节点是沿着轨道一步一步移动的,并不是跳跃移动的,当TA与地理位置绑定时,如图1所示,空间通信节点在大多数情况下处在跨越两个TA的情况,使得空间通信节点小区切换TAC的时机不够准确。
这里,空间通信节点包括却不限于卫星,低轨卫星,中轨卫星,高轨卫星,HAPS,飞行器等;空间通信节点可以包括但不限于透传模式的卫星,或是再生模式的卫星。
基于此,在本申请实施例中,为了使空间通信节点小区切换TAC的时机更为准确合理,基站确定了空间通信节点小区的TAC和/或RANA信息的更新条件,在更新条件被满足时,对空间通信节点小区的TAC和/或RANA信息进行更新。其中,更新条件基于第一区域、第二区域和第三区域中的至少两个区域之间的占比与设定阈值的大小关系确定,或者,更新条件表征为满足设定条件的第一空间通信节点小区的地理位置信息和/或移动时间信息,其中,所述第一区域表征所述第一空间通信节点小区的覆盖区域;所述第二区域表征第一TA或第一RANA对应的地理区域;所述第三区域表征第二TA或第二RANA对应的地理区域。基于上述方案,在空间通信节点在运动过程中,对应的空间通信节点小区的TAC和/或RANA信息的更新时机更加准确,有效保障了通信效率。
下面结合附图及实施例对本申请再作进一步详细的描述。
本申请实施例提供了一种跟踪区域更新方法,应用于第一基站,如图2所示,该方法包括:
步骤201:确定第一空间通信节点小区的第一TAC和/或第一RANA信息的第一更新条件。
其中,所述第一更新条件包括以下至少之一:
设定占比小于或者大于设定阈值;
第一空间通信节点小区的地理位置信息和/或移动时间信息满足设定条件。
上述设定占比基于第一区域、第二区域和第三区域中的至少两个区域之间的占比确定;所述第一区域表征所述第一空间通信节点小区的覆盖区域;所述第二区域表征第一TA或第一RANA对应的地理区域;所述第三区域表征第二TA或第二RANA对应的地理区域。
这里,第一RANA信息包括RANA码(RAN area code)和/或第一RANA对应的小区列表。
对于第一更新条件包括设定占比小于或者大于设定阈值的情况,这里,设定占比基于第一区域、第二区域和第三区域中的至少两个区域之间的占比确定,具体地,所述设定占比表征以下至少一种关系:
所述第一区域中所述第二区域的第一占比;
所述第一区域中所述第三区域的第二占比;
所述第一区域中的所述第二区域和所述第三区域的比值。
其中,第二区域和第三区域可以理解为空间通信节点对应的预先在地面上固定的相邻两个TA。
例如,结合图3,卫星小区1当前的TA为TA 1,当在卫星小区1的覆盖区域1中,TA 1对应的地理区域1与覆盖区域1的重合区域小于覆盖区域1的二分之一或四分之一,即第一占比小于二分之一或四分之一时,第一基站启动卫星小区1的TAC的更新;或者,当在卫星小区1的覆盖区域1中,与TA 1相邻且在卫星1运动方向上的TA 2对应的地理区域2与覆盖区域1的重合区域大于覆盖区域1的二分之一或四分之一,即第二占比大于二分之一或四分之一时,第一基站启动卫星小区1的TAC的更新;又或者,当在卫星小区1的覆盖区域1中,第二区域的区域面积与第三区域的区域面积的比值小于设定的比值阈值时,第一基站启动卫星小区1的TAC的更新。在启动了TAC的更新之后,卫星小区1对应的TAC由TA 1变成了TA 2或者TA 1+TA 2。
需要说明的是,在实施本发明实施例时,对设定占比的关系确定不限于第一TA和第二TA,可以理解地,还会有第三TA,……,第m TA(这里,m是大于1的自然数)。比如,所述第一区域表征所述第一空间通信节点小区的覆盖区域包括了第一TA,第二TA,第三TA,……,第m TA对应的地理区域。
此外,可以理解地,在实施本发明实施例时,对设定占比的关系确定不限于第一RANA,第二RANA还会有第三RANA,……,第n RANA(这里,n是大于1的自然数)。比如,所述第一区域表征所述第一空间通信节点小区的覆盖区域包括了第一RANA,第二RANA,第三RANA,……,第n RANA对应的地理区域。
对于第一更新条件包括第一空间通信节点小区的地理位置信息和/或移动时间信息满足设定条件的情况,基于空间通信节点预定的运行轨迹和运行周期,确定对应的空间通信节点小区在跨越两个TA时覆盖区域匹配的地理位置,或者确定对应的空间通信节点小区在跨越两个TA时距离上一次更新TAC和/或RANA信息的移动时间,这样,在空间通信节点小区的覆盖区域与设定的地理位置相匹配时,或者在空间通信节点小区距离上一次更新TAC和/或RANA信息的移动时间与设定的移动时间相匹配时,第一基站启动空间通信节点小区的TAC和或RANA信息的更新。
在一实施例中,所述方法还包括:
基于所述第一更新条件,对所述第一空间通信节点小区的第一TAC和/或第一RANA信息进行更新。
在一实施例中,所述确定第一空间通信节点小区的第一TAC和/或第一RANA信息的第一更新条件包括:
接收核心网设备和/或OAM设备下发的所述第一更新条件;
通过与核心网设备和/或OAM设备协商,确定所述第一更新条件;和/或,
通过与相邻的RAN节点协商,确定所述第一更新条件。
也就是说,可以由网管和/或核心网侧向第一基站告知第一空间通信节点小区的第一TAC和/或第一RANA信息的第一更新条件;或者,可以由第一基站与网管和/或核心网侧进行协商,共同确定出第一空间通信节点小区的第一TAC和/或第一RANA信息的第一更新条件;又或者,可以由第一基站与相邻的RAN节点进行协商,由第一基站确定出第一空间通信节点小区的第一TAC和/或第一RANA信息的第一更新条件。这样,在基于第一更新条件对第一空间通信节点小区的第一TAC和/或第一RANA信息进行更新时,核心网侧就可以准确地确定出需要寻呼的终端所在的空间通信节点小区最新的TAC和/或RANA信息,避免了因TAC和/或RANA信息的更新与核心网侧不同步而导致的漏寻呼情况的发生。
由于空间通信的移动速度较快,导致TAC和/或RANA信息的更新频度较高,为了减少因TAC和/或RANA信息更新频繁带来的终端对系统消息的频繁接收,在一实施例中,所述方法还包括:
向第一终端发送第一信息。
其中,所述第一信息中携带第一指示;所述第一指示用于指示所述第一TAC和/或第一RANA信息是否更新;或者,所述第一指示用于指示一定时间段里的不同的时间对应的不同的TAC和/或RANA信息。
在一实施例中,所述第一信息包括SIB 1和/或寻呼消息的第一DCI。
实际应用时,在SIB 1的valuetag中添加一个指示位,用于携带第一指示;或者,在第一DCI中携带第一指示。
这样,第一终端基于接收到的第一基站发送的携带第一指示的第一信息,便可以确定第一空间通信节点小区的第一TAC和/或第一RANA信息是否发生了更新,并在第一TAC和/或第一RANA信息发生了更新的情况下得以快速锁定系统消息中的更新的第一TAC和/或第一RANA信息。
在一实施例中,在第一空间通信节点运行至一个新的RAU的范围内的情况下,第一空间通信节点向网管或者向附近的基站请求获取第一列表。其中,所述第一列表表征所述第一空间通信节点进入的RANA的范围对应的空间通信节点小区的列表。第一空间通信节点在获取到第一列表之后,对第一列表中的空间通信节点小区进行寻呼。
因此,若第一基站为第一空间通信节点附近的基站,在一实施例中,所述方法还包括:
接收第一空间通信节点的第二请求;所述第二请求用于请求第一列表;所述第一列表表征所述第一空间通信节点进入的RANA的范围对应的空间通信节点小区的列表;
向所述第一空间通信节点发送所述第一列表。
在一实施例中,在所述接收第一空间通信节点的第二请求之前,所述方法还包括:
根据所述第一空间通信节点的移动轨迹周期性地或实时地更新RANA与空间通信节点小区的绑定关系。
这里,第一基站需要根据第一空间通信节点的移动轨迹,周期性地或者实时地维护第一列表,也就是更新各RANA对应的空间通信节点小区,或者维护一个携带时间信息的第一列表,使得当当前时间与第一列表中标示的时间信息相符时,该第一列表中的空间通信节点小区为第一空间通信节点当前进入的RANA的范围对应的空间通信节点小区。
若第一基站为位于第一列表中的空间通信节点小区对应的基站,那么在一实施例中,所述方法还包括:
发送第一请求;其中,
所述第一请求在第一空间通信节点进入新的RANA的范围内的情况下发送;或者根据所述第一空间通信节点获知的相邻的空间通信节点的移动位置,时间,TA和RANA中的至少一项信息发送;所述第一请求用于向相邻的RAN节点和/或OAM设备请求获取新的 RANA的范围内的非激活态(inactive)的终端的上下文。
这样,第一基站通过向相邻的RAN节点和/或OAM设备获取非激活态的终端的上下文,从而能够支持非激活态的终端的正常无线资源控制(RRC,Radio Resource Control)流程。
本申请实施例还提供了一种跟踪区域更新方法,应用于第一终端,所述方法包括:
向第一终端发送第一信息;其中,
所述第一信息中携带第一指示;所述第一指示用于指示所述第一TAC和/或第一RANA信息是否更新;或者,所述第一指示用于指示一定时间段里的不同的时间对应的不同的TAC和/或RANA信息。
在一实施例中,所述向第一终端发送第一信息,包括:
向所述第一信息包括SIB1和/或寻呼消息的第一DCI。
所述第一终端接收到所述第一信息的指示后,执行以下至少一种操作:
如果所述第一指示用于指示所述第一TAC和/或第一RANA信息更新了,则所述第一终端直接去读取更新后系统消息的第一TAC和/或第一RANA信息;
如果所述第一指示用于指示所述第一TAC和/或第一RANA信息更新了,如果所述第一终端没有移动,则忽略所述第一信息;
如果所述第一指示用于指示所述第一TAC和/或第一RANA信息更新了,如果所述第一终端移动了,则去读取更新后系统消息的第一TAC和/或第一RANA信息。
基于图2实施例示出的跟踪区域更新方法,相应地,本申请实施例还提供了一种跟踪区域更新方法,应用于第一终端,如图4所示,该方法包括:
步骤401:接收第一基站发送的第一信息。
其中,所述第一信息中携带第一指示;所述第一指示用于指示所述第一终端接入的第一空间通信节点小区的第一TAC和/或第一RANA信息是否更新;或者,所述第一指示用于指示一定时间段里的不同的时间对应的不同的TAC和/或RANA信息。
其中,在一实施例中,所述第一信息包括SIB1和/或寻呼消息的第一DCI。
实际应用时,在SIB 1的valuetag中添加一个指示位,用于携带第一指示;或者,在第一DCI中携带第一指示。
这样,第一终端基于接收到的第一基站发送的携带第一指示的第一信息,便可以确定第一空间通信节点小区的第一TAC和/或第一RANA信息是否发生了更新,并在第一TAC和/或第一RANA信息发生了更新的情况下得以快速锁定系统消息中的更新的第一TAC和/或第一RANA信息。并且,在第一TAC发生了更新的情况下,若终端本身未发生移动,则可以根据第一指示忽略本次系统消息的改变,或者忽略寻呼消息,而在终端本身发生了移动的情况下,也可以快速锁定系统消息中的更新的TAC,避免了因TAC的更新与核心网侧不同步而导致的漏寻呼情况的发生。
上文实施例中,基站在确定了关于TAC和/或RANA信息的更新条件之后,可以告知核心网侧,或者,在更新条件本身就由核心网侧下发至基站或是由核心网侧与基站协商决定的情况下,核心网无需基站告知便可明确该关于TAC和/或RANA信息的更新条件。实际应用时,在基站通过网管下发的方式或者通过与网管协商的方式确定关于TAC和/或RANA信息的更新条件的情况下,基站也可以选择不将更新条件告知核心网侧。针对核心网侧未得知更新条件的情况,基于图2实施例示出的跟踪区域更新方法,相应地,本申请实施例还提供了一种跟踪区域更新方法,应用于第一核心网设备,如图5所示,该方法包括:
步骤501,接收第一终端和/或RAN发送的所述第一终端的TA信息。
步骤502:在接收到第三请求时,根据接收到TA信息对对应的小区进行寻呼。
其中,所述第三请求表征寻呼所述第一终端的请求。
这里,当第一核心网设备收到对第一终端的寻呼请求后,第一核心网设备基于接收到的第一终端的TA信息,对TA信息对应的地理位置上的一个或多个空间通信节点小区都发送关于第一终端的寻呼。
在一实施例中,所述根据接收到TA信息对对应的小区进行寻呼,包括:
基于所述第三请求,查询至少一个第一TA信息;所述至少一个第一TA信息表征所述第一终端的TA信息,且所述至少一个第一TA信息基于所述第二终端上报的TA信息和/或RAN发送的所述第二终端的TA信息确定出;
根据存储的卫星的运行位置信息和/或系统消息告知的卫星的运行位置信息,确定所述至少一个第一TA信息中每个第一TA信息对应的地理位置上的一个或多个小区;
对确定出的一个或多个小区发送对所述第一终端的寻呼。
例如,在一时刻,第一核心网设备查询到TA 1对应的地理位置上有空间通信节点小区1和空间通信节点小区2,那么第一核心网设备向空间通信节点小区1和空间通信节点小区2都发送关于第二终端的寻呼消息。
实际应用时,由于核心网侧是按照TA为粒度来寻呼的,而目前,TA是和地理位置绑定的,空间通信节点在移动时,核心网侧无法合理地判断出空间通信节点小区的TA。而上述方案可以有助于核心网侧确定出寻呼范围,避免了因跟踪区域码TAC和/或RANA信息的更新与核心网侧不同步而导致的漏寻呼情况的发生。
在一实施例中,所述方法还包括以下至少一种:
当接收到的所述第一终端发送的所述第一终端的TA信息和RAN发送的所述第一终端的TA信息不一致时,将RAN发送的所述第一终端的TA信息确定为所述第一终端的TA信息;
当接收到的所述第一终端发送的所述第一终端的TA信息中的TAC多于一个时,将当前接收到的所述第一终端发送的所述第一终端的TA信息和上一次接收到的所述第一终端发送的所述第一终端的TA信息的交集中的TAC确定为所述第一终端的TA信息;
当接收到的所述第一终端发送的所述第一终端的TA信息中的TAC多于一个时,将当前接收到的所述第一终端发送的所述第一终端的TA信息确定为所述第一终端的TA信息;
其中,所述第一核心网设备利用确定出的所述第一终端的TA信息进行寻呼,定位和/或注册。
基于图2实施例示出的跟踪区域更新方法,相应地,本申请实施例还提供了一种跟踪区域更新方法,应用于第二终端,如图6所示,该方法包括:
步骤601:获取第二基站发送的第二空间通信节点小区的第二信息;或者,至少两次获取所述第二基站发送的所述第二空间通信节点小区的第二信息,并在两次获取到的所述第二空间通信节点小区的第二信息不相同的情况下,确定第三信息。
其中,所述第二信息指示对应的空间通信节点小区的至少一个TA信息;所述第二空间通信节点小区表征所述第二终端接入的空间通信节点小区;所述第三信息表征所述两次获取到的所述第二空间通信节点小区的第二信息的交集。
实际应用时,如果终端在空间通信节点小区的覆盖区域内发生了移动,那么移动后空间通信节点小区无论是否改变,终端都需要获取该空间通信节点小区的TA信息。
并且,在至少两次获取到的所述第二空间通信节点小区的第二信息不相同的情况下,第二终端确定所述两次获取到的所述第二空间通信节点小区的第二信息的交集。
例如,在t1时刻,第二终端获取到第二空间通信节点小区的TA是(TA1,TA2),到了t2时刻,第二终端获取到第二空间通信节点小区的TA是(TA0,TA1),那么,两次获取到的第二空间通信节点小区的第二信息的交集为TA 1,即,第三信息为TA 1。
在一实施例中,所述方法还包括以下至少一种:
在所述第二终端发生了移动的情况下,获取所述第二空间通信节点小区的第二信息;
在所述第二终端发生了移动的情况下,获取所述第二空间通信节点小区的第二信息,如果获取到的第二信息和所述第二终端上一次保存的所述第二空间通信节点小区的第二信息相同,则不发起TA更新过程;
在所述第二终端发生了移动的情况下,获取所述第二空间通信节点小区的第二信息,如果获取到的第二信息和所述第二终端上一次保存的所述第二空间通信节点小区的第二信息不同,则获取所述第三信息。
也就是说,每当第二终端发生了移动,则需要重新获取第二空间通信节点小区的第二信息。并且,在获取到第二空间通信节点小区的第二信息之后,第二终端将当前获取到的第二空间通信节点小区的第二信息与上一次保存,即上一次获取到的第二空间通信节点小区的第二信息进行比较,并根据比较结果确定是否发起对所述第二空间通信节点小区的TA更新过程。例如,第二终端当前获取到的第二空间通信节点小区的第二信息为TA1,如果第二终端上一次获取到的第二空间通信节点小区的第二信息也为TA1,那么第二终端不发起TA更新。
在一实施例中,除了根据比较结果确定是否发起对所述第二空间通信节点小区的TA更新过程,所述方法还包括以下至少一种:
将所述第三信息与所述第二终端移动前所述第二空间通信节点小区的第二信息进行比较,并根据比较结果确定是否发起对所述第二空间通信节点小区的TA的更新;
将所述第三信息中的TA信息,作为所述第二空间通信节点小区对应的TA信息;
基于所述第三信息确定所述第二空间通信节点小区所在的位置;
基于所述第三信息确定所述第二终端所在的位置;
将所述第三信息中的TA信息发送给RAN;
将所述第三信息中的TA信息通过NAS信息发送给核心网;
将所述第三信息中的TA信息发送给所述第二终端的NAS层;
将获取到的第二信息中的TA信息发送给RAN;
将获取到的第二信息中的TA信息通过NAS信息发送给核心网;
将获取到的第二信息中的TA信息发送给所述第二终端的NAS层。
