为了便于本领域内技术人员理解,本公开实施例列举了多个实施方式以对本公开实施例的技术方案进行清晰地说明。当然,本领域内技术人员可以理解,本公开实施例提供的多个实施例,可以被单独执行,也可以与本公开实施例中其他实施例的方法结合后一起被执行,还可以单独或结合后与其他相关技术中的一些方法一起被执行;本公开实施例并不对此作出限定。
为了更好地理解本公开任一个实施例所描述的技术方案,首先,对相关技术中的应用场景进行说明:
在一个实施例中,5G核心网络支持用户终端通过卫星接入网络。
在一个实施例中,如果使用卫星接入为用户提供网络服务,卫星接入可能受星链中的卫星数量不足或者卫星波束间断等的影响,向地面提供的信号覆盖可能是非连续的,即用户在某一区域通过卫星接入网络时,存在特定时间段无卫星信号覆盖的情况。因此,用户在接入网络以及开展业务的过程中,需要考虑卫星接入的非连续性覆盖。
例如,让UE在未有信号覆盖时,处于休眠或节电状态,以节省终端功耗,当卫星信号恢复覆盖的时候,UE及时唤醒重新和网络建立连接,或者开展业务。
再例如,网络侧如果需要向UE发送下行信令或数据的时候,需要判断此刻UE是否有卫星信号覆 盖,如果有覆盖,则将所述信令或数据发送给UE,如果未有信号覆盖,则网络侧需要缓存所述信令或数据,在判断卫星信号恢复对所述UE的覆盖时,在将所述信令或数据发送给UE。总之,在用户使用卫星接入网络,并且卫星接入存在非连续覆盖的情况下,终端和网络侧在发生信令或者数据时,都需要结合卫星覆盖情况判断UE是否处于卫星信号覆盖下,只有在有卫星信号覆盖下才进行通信交互。
上述方案实现了当UE处于无卫星信号覆盖的情况下,将UE状态保持在空闲状态,既保证了UE没有离开网络,以便信号覆盖恢复时,UE可以立即实现状态转换,快速开展业务,又实现了在无信号覆盖期间节省终端功耗的目的。但是,如果信号无覆盖时间过长,例如UE获得20分钟所述卫星接入信号覆盖后间隔10小时才能再次获得20分钟信号覆盖,这就意味着在10小时之内UE保持休眠状态,无法开展业务。
在一个实施例中,在UE即将失去当前卫星接入覆盖时,考虑使用其他可用的接入方式提供补充接入,例如,当UE即将失去卫星接入1的覆盖时,在UE当前位置区域还有其他可用卫星接入或者陆地蜂窝接入,通过当前卫星接入1的基站发起跨无线接入技术(inter-RAT)的切换,以便UE在即将失去卫星接入1的覆盖时,使用卫星接入2或者陆地蜂窝为UE提供补充接入,使得UE在失去卫星接入1的覆盖时,可以继续开展业务。然后跨RAT的切换往往也存在因为各种因素制约而发生切换失败的情况,无法可靠解决上述卫星接入的非连续覆盖问题。
