Description

配置小区重选参数、小区重选方法及装置、存储介质 技术领域
本公开涉及通信领域,尤其涉及配置小区重选参数、小区重选方法及装置、存储介质。
背景技术
目前,对于处于RRC(Radio Resource Control,无线资源控制)空闲态或非激活态的终端,可以根据S准则和R准则进行小区重选。以S准则为例,对于同频邻小区测量,如果服务小区的小区信号质量大于同频邻小区的信号质量门限值,可以不进行邻小区测量,如果服务小区的小区信号质量小于同频邻小区的信号质量门限值,终端需要进行邻小区测量。异频邻小区的测量方式与同频邻小区的测量方式类似。终端同样可以在服务小区的小区信号质量小于异频邻小区的信号质量门限值的情况下,进行异频邻小区测量。
在NTN(Non-terrestrial Networks,非陆地网络)系统中,除了GEO(Geostationary Earth Orbiting,地球同步轨道)卫星以外,随着卫星的移动,feeder link switch(馈线链路交换)是必然存在的。其中feed link就是指卫星与地面网关之间的链路。在进行feeder link switch时,服务小区会不可用,如果终端根据S准则启动对邻区的测量,可能会导致终端还没有启动邻小区测量,而服务小区不可用的问题。

具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
在本公开使用的术语是仅仅出于描述特定实施例的目的,而非旨在限制本公开。在本公开和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式,除非上下文清楚地表示其他含义。还应当理解,本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解,尽管在本公开可能采用术语第一、第二、第三等来描述各种信息,但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如,在不脱离本公开范围的情况下,第一信息也可以被称为第二信息,类似地,第二信息也可以被称为第一信息。取决于语境,如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
除了GEO卫星之外的其他卫星相对于地面都是不断运动的,在进行feeder link switch时,参照图1所示,在T1时刻,该卫星与GW(Gateway,地面站)1相连接,在T2时刻,卫星开始了feeder link switch,此时卫星可能与GW1和GW2同时保持连接,并且对于空闲态或非激活态的终端而言,需要进行小区重选,从小区1重选到小区2,在T3时刻,完成feeder link switch,终端也完成小区重选。由于feeder link switch,在T2时刻,小区1会不可用,导致终端还未启动对邻小区的测量,从而通过小区重选进入小区2的情况下,小区1就无法为终端提供服务了。
为了解决上述问题,本公开提供了以下配置小区重选参数和小区重选方案。
下面先从基站侧介绍一下本公开的配置小区重选参数的方案。
本公开实施例提供了一种配置小区重选参数的方法,参照图2所示,图2是根据一实施例示出的一种配置小区重选参数的方法流程图,该方法可以由基站执行,包括以下步骤:
在步骤201中,为终端配置用于进行小区重选的目标时间参数,所述目标时间参数至少包括第一时间参数,所述第一时间参数用于指示所述小 区的服务时间信息。
在步骤202中,发送所述目标时间参数。
上述实施例中,实现了由网络侧为终端配置用于进行小区重选的目标时间参数的目的。
在一个可能的实现方式中,第一时间参数可以包括以下至少一项:第一时长参数、第一时间点参数。
其中,第一时长参数可以用于指示小区能够提供服务的服务时长信息,例如,第一时长参数用于指示该小区能够提供服务的服务时长为2小时。
第一时间点参数用于指示所述小区停止提供服务的时间点信息,小区会在该第一时间点参数指示的时刻停止提供服务。可选地,第一时间点参数指示的为绝对时间,例如UTC(Universal Time Coordinated,世界标准时间)。例如,第一时间点参数指示上午9点,那么该小区会在上午9点停止提供服务。
上述实施例中,第一时间参数可以通过小区能够提供服务的服务时长对应的第一时长参数,或者该小区停止提供服务的时间点对应的第一时间点参数来表示,实现简便,可用性高。
在一些可选实施例中,参照图3所示,图3是根据一实施例示出的一种配置小区重选参数的方法流程图,该方法可以由基站执行,包括以下步骤:
在步骤301中,为终端配置用于进行小区重选的目标时间参数,所述目标时间参数至少包括第一时间参数,所述第一时间参数用于指示所述小区的服务时间信息。
在步骤302中,广播包括所述目标时间参数的系统消息。
上述实施例中,基站可以通过广播包括所述目标时间参数的系统消息,使得终端接收到目标时间参数。实现了由网络侧为终端配置用于进行小区重选的目标时间参数的目的。
在一些可选实施例中,参照图4所示,图4是根据一实施例示出的一 种配置小区重选参数的方法流程图,该方法可以由基站执行,包括以下步骤:
在步骤401中,为终端配置用于进行小区重选的目标时间参数,所述目标时间参数至少包括第一时间参数,所述第一时间参数用于指示所述小区的服务时间信息。
在步骤402中,广播包括所述目标时间参数的系统消息。
在本公开实施例中,基站可以通过广播系统消息,使得终端接收到网络侧为终端配置的目标时间参数。
在步骤403中,响应于所述目标时间参数包括用于指示所述小区能够提供服务的服务时长信息的第一时长参数,在系统消息的每个发送周期,更新所述系统消息中包括的所述第一时长参数的参数值。
在本公开实施例中,在基站通过系统消息将目标时间参数发送给终端,且其中的目标时间参数包括第一时长参数的情况下,在系统消息的每个发送周期,基站需要更新系统消息中包括的第一时长参数的参数值。
在一个可能的实现方式中,基站可以基于该小区能够提供服务的最大服务时长和系统消息的每个发送周期的周期时长,确定所述每个发送周期所述系统消息中包括的所述第一时长参数的参数值。
基站可以按照以下公式确定每个发送周期系统消息包括的第一时长参数的参数值T:
T=T max-nT’       公式1
其中,T max是小区能够提供服务的最大服务时长,T’是每个发送周期的周期时长,n用于指示从该小区开始提供服务起,已经经历的系统消息的发送周期的数目,n的取值范围可以是自然数。
例如,每个发送周期,系统消息中包括的第一时长参数的参数值T的取值可以依次为:T max、T max-T’、T max-2T’、……以此类推,直到该小区停止提供服务。
上述实施例中,基站可以通过广播系统消息,使得终端接收到目标时 间参数。且基站会在系统消息的每个发送周期,更新系统消息中包括的第一时长参数的参数值,使得在任一个发送周期内进入该小区的终端,均可以通过系统消息,准确获得小区提供服务的时间信息。
在本实施例中,在基站通过系统消息将目标时间参数发送给终端,且其中的目标时间参数包括第一时间点参数的情况下,由于第一时间点参数指示的是绝对时间,不会随着已经历的系统消息的发送周期数目发生改变,因此,目标时间参数包括第一时间点参数的情况下,基站无需更新系统消息中包括的第一时间点参数的参数值。
上述实施例中,基站可以通过系统消息,将基站为终端配置的该小区提供服务的时间信息准确提供给终端,可用性高。
在一些可选实施例中,参照图5所示,图5是根据一实施例示出的一种配置小区重选参数的流程图,该方法可以由基站执行,包括以下步骤:
在步骤501中,为终端配置用于进行小区重选的目标时间参数,所述目标时间参数至少包括第一时间参数,所述第一时间参数用于指示所述小区的服务时间信息。
在步骤502中,广播包括所述目标时间参数的系统消息。
在本公开实施例中,基站可以通过广播系统消息,使得终端接收到目标时间参数。
在步骤503中,响应于所述目标时间参数包括用于指示所述小区能够提供服务的服务时长信息的第一时长参数,在系统消息的每个发送周期,更新所述系统消息中包括的所述第一时长参数的参数值。
在步骤504中,不触发系统消息更新通知。
按照相关技术,系统消息发生更新,需要通知该小区内的终端,但在本公开实施例中,基站如果更新了系统消息中包括的第一时长参数的参数值,不会触发系统消息更新通知。即终端侧在进入该小区,并通过接收系统消息,确定其中包括的第一时长参数的参数值后,终端会基于该第一时长参数的参数值,进行小区重选。这个过程中,针对终端而言,第一时长 参数的参数值不会发生改变,因此,即使网络侧在系统消息的下个发送周期,更新了系统消息中的第一时长参数的参数值,也无需通知终端,即无需触发系统消息更新通知。
上述实施例中,基站更新了系统消息中包括的所述第一时长参数的参数值之后,不会通知终端系统消息发生了更新,确保终端可以准确获得该小区提供服务的时间信息,可用性高。
在一些可选实施例中,参照图6所示,图6是根据一实施例示出的一种配置小区重选参数的方法流程图,该方法可以由基站执行,包括以下步骤:
在步骤601中,为终端配置用于进行小区重选的目标时间参数,所述目标时间参数至少包括第一时间参数,所述第一时间参数用于指示所述小区的服务时间信息。

上述实施例中,基站可以在终端从连接态切换到其他状态的情况下, 通过RRC连接释放消息,将基站为终端配置的该小区提供服务的时间信息提供给终端,可用性高。
在一些可选实施例中,参照图8所示,图8是根据一实施例示出的一种配置小区重选参数的方法流程图,该方法可以由基站执行,包括以下步骤:
在步骤801中,为终端配置用于进行小区重选的目标时间参数,所述目标时间参数至少包括第一时间参数,所述第一时间参数用于指示所述小区的服务时间信息。
在步骤802中,响应于确定所述终端从连接态切换到空闲态或非激活态,所述目标时间参数包括用于指示所述小区能够提供服务的服务时长信息的第一时长参数,基于所述小区能够提供服务的最大服务时长和已提供的服务时长,确定所述RRC连接释放消息中包括的所述第一时长参数的参数值。
在本公开实施例中,RRC连接释放消息中包括的所述第一时长参数的参数值T可以为该小区能够提供服务的最大服务时长T max和该小区目前已提供的服务时长T ser的差值,即T=T max-T ser
在步骤803中,向所述终端发送包括所述目标时间参数的RRC连接释放消息。
在上述实施例中,基站可以在确定终端从连接态切换到空闲态,或者切换到非激活态的情况下,向终端发送包括该目标时间参数的RRC release(RRC连接释放)消息。将基站为终端配置的该小区提供服务的时间信息通过RRC消息准确提供给终端,可用性高。
在一些可选实施例中,目标时间参数除了可以包括上述第一时间参数之外,还可以包括第二时间参数,该第二时间参数可以用于指示邻小区的服务时间信息。
在一个可能的实现方式中,第二时间参数包括以下至少一项:第二时长参数、第二时间点参数、第三时间点参数。
其中,第二时长参数用于指示邻小区即将为该终端提供服务的服务时长信息,第二时间点参数用于指示邻小区提供服务的起始时间点信息,第三时间点参数用于指示邻小区停止提供服务的时间点信息,邻小区将在第三时间点参数指示的时间点停止提供服务。其中,第二时间点参数和第三时间点参数可以用绝对时间表示。
上述实施例中,基站为终端配置的用于进行小区重选的目标时间参数既可以包括该小区提供服务的时间信息,也可以包括邻小区提供服务的时间信息。从而确保终端可以基于目标时间参数,及时进行小区重选。
需要说明的是,在本公开实施例中,如果基站广播包括目标时间参数的系统消息,且目标时间参数中包括了第二时间参数,第二时间参数的参数值无需随着系统消息的发送周期进行更新。
同样地,如果基站向终端发送包括目标时间参数的RRC消息,且目标时间参数中包括第二时间参数,该第二时间参数不会发生改变。

相应地,在终端不仅接收到包括所述第一时长参数的系统消息,还接收到包括所述第一时长参数的RRC连接释放消息的情况下,终端将所述小区重选定时器的定时时长配置为该RRC连接释放消息中第一时长参数的参数值。
在步骤1003中,响应于所述小区重选定时器超时,进行小区重选。
在本公开实施例中,终端可以在小区重新定时器超时时,立即进行邻小区测量,并基于邻小区测量结果,进行小区重选。其中,邻小区测量包括但不限于以下至少一项:获取邻小区ID,读取邻小区的系统消息,测量 邻小区的信号质量等。
上述实施例中,终端可以基于基站配置的目标时间参数中第一时长参数,进行小区重选,实现了及时进行小区重选的目的,确保了终端业务的正常进行。
在一个可能的实现方式中,终端可以通过小区重选进入该小区,且终端接收到包括第一时长参数的系统消息,此时,终端触发启动该小区重选定时器。该小区重选定时器的定时时长为系统消息中第一时长参数的参数值。
在另一个可能的实现方式中,终端由连接态切换到空闲态或非激活态,且接收到包括所述第一时长参数的RRC连接释放消息,此时,终端可以触发启动所述小区重选定时器。且小区重选定时器的定时时长为RRC连接释放消息中第一时长参数的参数值。
在另一个可能的实现方式中,终端由连接态切换到空闲态或非激活态,且接收到的RRC连接释放消息中不包括第一时长参数,但接收到的所述系统消息中包括所述第一时长参数,此时,终端触发启动所述小区重选定时器。该小区重选定时器的定时时长为系统消息中第一时长参数的参数值。
当然,如果终端由连接态切换到空闲态或非激活态,接收到的RRC连接释放消息中包括第一时长参数,且接收到的所述系统消息中包括所述第一时长参数,终端触发启动所述小区重选定时器,且小区重选定时器的定时时长为RRC连接释放消息中第一时长参数的参数值。

在本公开实施例中,终端可以在第一时间点指示的时间点之前或指示的时间点,进行邻小区测量,并基于邻小区测量结果,进行小区重选。其中,邻小区测量包括但不限于以下至少一项:获取邻小区ID,读取邻小区的系统消息,测量邻小区的信号质量等。
上述实施例中,终端可以基于基站配置的目标时间参数中第一时间点参数,进行小区重选,实现了及时进行小区重选的目的,确保了终端业务的正常进行。
在一些可选实施例中,目标时间参数还可以包括第二时间参数,所述第二时间参数用于指示邻小区的服务时间信息。
可选地,所述第二时间参数包括以下至少一项:用于指示邻小区即将为所述终端提供服务的服务时长信息的第二时长参数、用于指示邻小区提供服务的起始时间点信息的第二时间点参数、用于指示邻小区停止提供服务的时间点信息的第三时间点参数。

在一个可能的实现方式中,终端可以选择第二时长参数指示的服务时长最长的邻小区作为进行小区重选时的目标邻小区。
上述实施例中,终端可以基于目标时间参数中包括的用于指示邻小区提供服务的时长信息的第二时长参数,确定进行小区重选时待切换的目标邻小区,从而可以在进行小区重选时,基于基站配置的目标时间参数,选择更合理的目标邻小区,可用性高。
在一些可选实施中,如果目标时间参数还包括第二时间点参数和所述第三时间点参数中的至少一项,终端可以基于所述第二时间点参数和所述 第三时间点参数中的至少一项,确定进行小区重选时待切换的目标邻小区。
在一个可能的实现方式中,邻小区的第二时间点参数指示的时间点均位于当前小区停止提供服务的时间点之后,终端可以选择第二时间点参数指示的时间点最接近当前小区停止提供服务的时间点的邻小区,作为目标邻小区。
在另一个可能的实现方式中,邻小区的至少一个第二时间点参数指示的时间点位于当前小区停止提供服务的时间点之前,终端可以在这些邻小区中,选择小区信号质量最好的邻小区作为目标邻小区。
