S210,在终端设备的无线资源控制RRC连接建立或恢复的过程中,所述终端设备接收网络设备发送的第一消息,所述第一消息包括所述网络设备配置或更新的直连链路资源的信息。
可选地,在本申请实施例中,该直连链路资源为用于直连通信的资源,这里的直连链路可以为用于D2D通信或者车辆到其他设备(Vehicle to Everything,V2X)的直连链路,也就是说,该直连链路资源可以用于终端和终端之间的直连通信,或终端与其他设 备之间的直连通信,等等,但本申请实施例并不限于此。
可选地,在本申请实施例中,该终端设备处于非连接态,例如,IDLE态或非激活态,也就是说,终端设备还未与网络设备建立连接,或者之前建立的连接已断开。
在本申请实施例中,处于IDLE态或非激活态的终端设备可以发起无线资源控制(Radio Resource Control,RRC)连接建立(setup)或恢复(resume)过程,建立或恢复与网络设备的RRC连接。在该RRC连接建立或恢复过程中,网络设备可以向终端设备发送第一消息,通过该第一消息为该终端设备配置或更新直连链路资源。也就是说,在本申请实施例中,终端设备可以在RRC连接建立或恢复过程中获取网络设备配置或更新的直连链路资源,而不必等待系统信息或专用信令获取网络设备配置或更新的直连链路资源,能够实现直连链路资源的及时快速的配置,同时也能够避免由于资源不足导致影响直连通信的问题。
可选地,在本申请实施例中,该第一消息可以为现有的RRC连接或恢复过程中网络设备向终端设备发送的任一消息,例如,RRC连接建立(RRC Connection Setup)消息,RRC连接恢复(RRC Connection Resume)消息,RRC连接拒绝(RRC Connection Reject)消息或RRC连接释放(RRC Connection Release)消息等;或者也可以在RRC连接或恢复过程中新增消息,专门用于网络设备配置或更新直连链路资源。
应理解,该RRC连接建立消息可以用于指示网络设备同意与该终端设备建立RRC连接,该RRC连接恢复消息用于指示网络设备同意与该终端设备恢复RRC连接,该RRC连接拒绝消息用于指示网络设备拒绝与该终端设备建立RRC连接,RRC连接释放消息用于指示网络设备释放与终端设备的RRC连接。
可选地,在一些实施例中,该方法200还可以包括:
所述终端设备向所述网络设备发送第二消息,所述第二消息包括指示信息,所述指示信息用于指示所述RRC连接建立或恢复过程用于请求配置或更新所述直连链路资源。
也就是说,在RRC连接建立或恢复的过程中,该终端设备可以向网络设备发送第二消息,通过在该第二消息中携带指示信息,向该网络设备请求配置或更新直连链路资源,进一步地,该网络设备可以根据该第二消息,向该终端设备发送第一消息,从而实现该终端设备的直连链路资源的配置或更新。
可选地,在一些情况下,若该终端设备上已配置的直连链路资源不足,例如若该终端设备所在的直连链路上的终端设备的数量增加或终端设备的业务量增加导致当前配置的直连链路资源不足,或者已配置的直连链路资源不能满足当前的直连通信的传输需求,例如,服务质量(Quality of Service,QoS)或时延需求等。此时,该终端设备需要请求获取新的直连链路资源,并且,该直连链路资源并非用于所有的终端设备,此情况下,该终端设备可以不必通过系统信息或专用信令获取直连链路资源,而是通过RRC连接建立或恢复过程请求获取该直连链路资源,有利于实现直连链路资源的及时配置或更新。
可选地,该第二消息可以为现有的RRC连接或恢复过程中终端设备向网络设备发送的任一消息,例如,RRC连接请求(RRC Connection Request),或RRC连接恢复请求(RRC Connection Resume Request),或者也可以为RRC连接建立完成(RRC Connection Setup Complete),RRC连接恢复完成(RRC Connection Resume Complete)等,或者也可以在RRC连接或恢复过程中新增消息,专门用于终端设备请求配置或更新直连链路资源。可以理解,若该第二消息为现有的RRC消息,在该第二消息中不包括指示信息时,该第二消息可以与现有的RRC消息的作用相同,在该第二消息包括指示信息时,该第二消息可以兼有现有的RRC消息的作用和请求配置或更新直连链路资源的作用,或者,该第二消息也可以只具有请求配置或更新直连链路资源的作用,此情况下,该RRC连接建立或恢复过程实际上是直连链路资源的配置或更新的过程。
应理解,该RRC Connection Request用于请求与网络设备建立连接,该RRC Connection Resume Request用于请求与网络设备重新建立连接,该RRC Connection Setup  Complete用于指示与网络设备连接建立完成。
可选地,在本申请实施例中,所述直连链路资源的信息包括以下中的至少一项:
用于直连链路发送或接收的第一资源或第一资源池;
所述第一资源或所述第一资源池的使用条件;
所述第一资源或第一资源池与第二资源或第二资源池的关系,其中,所述第二资源或所述第二资源池为在所述第一资源或所述第一资源池之前配置的直连链路资源。
可选地,在本申请实施例中,所述第一资源或所述第一资源池的使用条件包括以下中的至少一项:
所述第一资源或所述第一资源池的使用时间范围、使用区域范围、支持的终端设备的数量和支持的业务量的大小。
作为示例而非限定,所述使用区域范围为以下中的一种:
单个小区,多个小区、跟踪区(Tracking Area,TA)和接入网区域(RAN Area,RA)。
可选地,在一些情况下,该网络设备可以终端设备的历史移动信息,确定该终端设备经常出现的小区,TA或RA,进一步地,为上述区域配置对应的直连链路资源,以便于该终端设备移动至上述区域时,可以直接使用配置的直连链路资源进行直连通信,从而能够提升通信效率。这里,该直连链路资源的使用区域范围可以包括该终端设备经常出现的小区,TA或RA。
可选地,该使用时间范围可以为一个定时器,即在定时器失效后,该第一资源或第一资源池失效,即不可用。
可选地,在本申请实施例中,该直连链路资源的信息还可以包括第二资源或第二资源池的使用条件,例如,所述第二资源或所述第二资源池的使用条件包括以下中的至少一项:
所述第二资源或所述第二资源池的使用时间范围、使用区域范围、支持的终端设备的数量和支持的业务量的大小。
也就是说,该网络设备也可以配置旧的直连链路资源的使用条件,这样,终端设备可以在满足不同的使用条件时,使用对应的直连链路资源,有利于满足不同场景的需求。
例如,第一资源或第一资源池(即新的直连链路资源)中的资源较丰富,第二资源或第二资源池(即旧的直连链路资源)中的资源较少,则可以配置第一资源或第一资源池的使用条件是直连链路上的终端设备的数量不超过第一阈值,该第二资源或第二资源池的使用条件为直连链路上的终端设备的数量不超过第二阈值,其中,该第二阈值小于第一阈值。假设该第一阈值为8,该第二阈值为5,则在直连链路上的终端设备的数量大于5的情况下,该终端设备可以选择使用第一资源或第一资源池进行直连通信,有利于避免使用旧的直连链路资源导致资源不足影响直连通信的问题。
又例如,假设在终端设备处于小区1中时,使用第一资源或第一资源池的直连通信的质量较优,在终端设备处于小区2中时,使用第二资源或第二资源池的直连通信的直连较优,则可以配置第一资源或第一资源池的使用条件是小区1,第二资源或第二资源池的使用条件为小区2,则在终端设备当前所处小区为小区1的情况下,该终端设备可以选择使用第一资源或第一资源池进行直连通信,有利于提升通信质量和通信效率。
可选地,在一些实施例中,该网络设备还可以配置所述第一资源或第一资源池与第二资源或第二资源池的关系,例如可以为互补关系或替代关系,其中,所述互补关系用于指示所述第一资源或第一资源池与所述第二资源或所述第二资源池都能够用于直连链路通信,所述替代关系用于指示在配置所述第一资源或第一资源池的情况下,不再使用所述第二资源或所述第二资源池。
也就是说,该网络设备不仅可以给终端设备配置或更新直连链路资源,同时还可以给终端设备配置旧的直连链路资源的使用方式,例如,可以在配置了新的直连链路资源的情况下,只使用该新的直连链路资源进行直连通信,或者,也可以将新的直连链路资 源和旧的直连链路资源合并作为直连通信的资源,或者,若配置了新的直连链路资源和旧的直连链路资源的使用条件,也可以根据使用条件使用对应的直连链路资源进行直连通信,本申请实施例对此不作限定。

可选地,在一些情况下,若该终端设备的移动性较强,该网络设备可以终端设备的历史移动信息,确定该终端设备经常出现的小区,TA或RA,进一步地,为上述区域配置对应的直连链路资源,以便于该终端设备移动至上述区域时,可以直接使用配置的直 连链路资源进行直连通信,从而能够提升通信效率。
