- the 5G core network supports user terminals to access the network through satellites.
- the satellite access may be affected by the insufficient number of satellites in the star chain or the interruption of satellite beams, etc., and the signal coverage provided to the ground may be discontinuous, that is, the user When accessing the network through satellite in a certain area, there may be no satellite signal coverage during a specific period of time. Therefore, users need to consider the discontinuous coverage of satellite access when accessing the network and conducting services.
- the UE when there is no signal coverage, the UE is placed in a dormant or power-saving state to save terminal power consumption. When the satellite signal coverage is restored, the UE wakes up in time to re-establish a connection with the network or carry out services.
- the network side needs to send downlink signaling or data to the UE, it needs to determine whether the UE has satellite signal coverage at the moment. If there is coverage, the signaling or data will be sent to the UE. If there is no signal coverage, Then the network side needs to cache the signaling or data, and send the signaling or data to the UE when it is determined that the satellite signal has restored coverage of the UE.
- both the terminal and the network side need to determine whether the UE is covered by the satellite signal based on the satellite coverage. Only Communication interaction is only carried out when there is satellite signal coverage.
- the above solution realizes that when the UE is without satellite signal coverage, the UE status is kept in the idle state, which not only ensures that the UE does not leave the network, so that when the signal coverage is restored, the UE can immediately implement state transition, quickly carry out services, and achieve In order to save terminal power consumption during periods of no signal coverage.
- the signal is not covered for too long, for example, after the UE obtains the satellite access signal coverage for 20 minutes, it will take 10 hours to obtain 20 minutes of signal coverage again, which means that the UE remains dormant within 10 hours and cannot carry out operations. business.
- the UE when the UE is about to lose the current satellite access coverage, consider using other available access methods to provide supplementary access. For example, when the UE is about to lose the coverage of satellite access 1, it is still possible to provide supplementary access in the UE's current location area. If there are other available satellite access or terrestrial cellular access, the inter-radio access technology (inter-RAT) handover is initiated through the base station of the current satellite access 1 so that the UE can use the satellite access when it is about to lose the coverage of satellite access 1. Satellite access 1 or satellite access 1 provides supplementary access to the UE, so that the UE can continue to carry out services when it loses the coverage of satellite access 1.

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。
