具体实施方式
在对本申请实施例的技术方案进行介绍之前,先对相关技术进行说明。
图1是相关技术中建立网络连接的示意图,如图1所示,在不在网络覆盖 范围(out of coverage)的终端包括UE2和UE3,在网络覆盖范围内(in coverage)的终端为UE1,UE2和UE3不能直接与网络进行连接,只能通过UE1与网络建立连接。
但是,在上述场景中,如果UE1无法保持与网络的连接,即Uu链路出现问题,那么UE1无法继续为UE2和UE3提供接入网络的服务,此时UE2和UE3需要各自进行测量,寻找新的可提供服务网络连接的UE,并各自与选择的候选(candidate)目标UE发起链路(sidelink)建立过程。
也就是说,作为中间节点的终端出现问题之后,与该中间节点连接的其他UE需要各自开展测量,并与新的目标UE进行sidelink建立。
但实际上,可以与同一中间节点建立sidelink连接,说明这几个UE的信道状况接近,如果这些UE的位置或者信道状况继续保持相对稳定,即使源中间节点无法继续服务,这几个UE很高概率还是可以重新关联到同一个新的目标UE,那么每一个UE都各自进行测量,然后都各自重新建立sidelink是一种资源和功耗浪费。
针对上述问题,提出一种优化方法,如果同一中间节点关联的多个UE的位置或者信道状况保持相对稳定,并不需要每一个UE都开展测量工作,可以只基于某个或者某几个UE进行测量。确定目标中间节点之后,这几个终端均可以关联到同一个中间节点。上述方法可以降低终端功耗,提升系统性能。
基于此,本申请实施例中,接收第二终端发送的第一信息;所述第一信息包括相应第二终端与所述第一终端之间的第一链路质量、在第一时间窗口内的所述第一链路质量的变化量、相应第二终端与第三终端之间的第二链路质量、在第二时间窗口内的所述第二链路质量的变化量和相应第二终端的位置信息中至少之一。

需要说明的是,如果所述差值小于或等于第一门限,则说明多个第二终端各自与第一终端之间的链路质量相近或信道状况相近。比如,以所述第一终端为中心,多个第二终端位于一定半径的覆盖范围内。如此,可以将与所述第一终端之间的链路质量相近或信道状况相近的第二终端作为第四终端。
以所述第四变化量为例,在第三时间窗口内的所述第一链路质量的第四变 化量可以是根据在第一时间窗口内的所述第一链路质量的第一变化量确定的。其中,所述第三时间窗口的长度是所述第一时间窗口的长度的整数倍。
举例来说,假设第一时间窗口为1~5s,第三时间窗口为1s~10s,如此,在1~5s获取所述第一链路质量的第一变化量,在6~10s获取所述第一链路质量的第一变化量,并将两个第一变化量求差得到差值,将所述差值作为在第三时间窗口内的所述第一链路质量的第四变化量。
需要说明的是,如果所述差值小于或等于第一门限,则说明多个第二终端各自与第一终端之间的链路质量相近或信道状况相近。如此,可以将与所述第一终端之间的链路质量相近或信道状况相近的第二终端作为第四终端。
以所述第五变化量为例,所述第二链路质量的第五变化量可以是指由所述第一信息获取的在第二时间窗口内的所述第二链路质量的第二变化量;或者,是指根据所述第一信息获取的第二链路质量计算得到的差值。
举例来说,假设第一终端用UE1表示,第二终端用UE2表示,所述第三终端用UE3表示,T1时刻获取UE2与UE3之间的第二链路质量,T2时刻获取UE2与UE3之间的第二链路质量,如此,将T1时刻获取的第二链路质量与T2时刻获取的第二链路质量求差得到差值,并将所述差值作为所述第二链路质量的第五变化量。
再例如,假设第一终端用UE1表示,第二终端用UE2、UE3表示,所述第三终端用UE4表示,根据第一信息获取UE2与UE4之间的第二链路质量以及UE3与UE4之间的第二链路质量,如此,将不同第二终端到第三终端之间的第二链路质量求差得到差值,并将所述差值作为所述第二链路质量的第五变化量。
需要说明的是,如果所述差值小于或等于第二门限,则说明多个第二终端各自与第一终端之间的链路质量相近或信道状况相近。如此,可以将与所述第一终端之间的链路质量相近或信道状况相近的第二终端作为第四终端。
以所述第六变化量为例,在第四时间窗口内的所述第二链路质量的第六变化量可以是根据在第二时间窗口内的所述第二链路质量的第一变化量确定的。其中,所述第四时间窗口的长度是所述第二时间窗口的长度的整数倍。
举例来说,假设第二时间窗口为1~5s,第四时间窗口为1s~10s,如此,在1~5s获取所述第二链路质量的第二变化量,在6~10s获取所述第二链路质量的第二变化量,并将两个第二变化量求差得到差值,将所述差值作为在第四时间 窗口内的所述第二链路质量的第六变化量。
需要说明的是,如果所述差值小于或等于第二门限,则说明多个第二终端各自与第一终端之间的链路质量相近或信道状况相近。如此,可以将与所述第一终端之间的链路质量相近或信道状况相近的第二终端作为第四终端。
以相对位置固定为例,所述第一终端根据所述第二终端的位置信息,判断在一定时长内,若所述第二终端的位置变化较小,则判断所述第二终端与所述第一终端之间的相对位置固定。其中,所述位置变化较小可以是指经度的变化小于一定门限,和/或,维度的变化小于一定门限。
进一步地,当所述第二终端有多个时,若多个第二终端各自与所述第一终端之间的位置均相对固定,如此,可以将与所述第一终端之间的相对位置固定的第二终端作为第四终端。
可以理解的是,所述第一终端还可以获取所述第二终端与自身的相对位置,判断在一定时长内,若所述第二终端与自身的相对位置满足一定门限,则判断所述第二终端与所述第一终端之间的位置相近,也可以确定所述第二终端与所述第一终端之间的相对位置固定。

下面对采用第一种方式确定进行测量的终端的过程进行详细描述。
实际应用时,当所述第二终端有多个,且从多个第二终端中选出多个第四终端时,多个第四终端之间可以交互第二信息,以自主确定进行测量的终端。
基于此,在一实施例中,所述方法还包括:
接收所述第四终端发送的第二信息;所述第二信息用于指示所述第四终端是否进行测量。
