本申请属于通信技术领域,具体涉及一种小区切换方法、装置及相关设备。This application belongs to the field of communication technology, and specifically relates to a cell switching method, device and related equipment.
非地面网络(Non-Terrestrial Networks,NTN)场景中,由于卫星移动会导致频繁的服务链路(service link)和馈线链路(feeder link)切换,从而导致NTN小区内的所有终端都需要频繁地执行小区切换过程。此外,由于NTN小区服务的覆盖范围大于地面网络(Terrestrial Networks,TN)小区,进而服务的终端数量也会更多,卫星的移动也就会导致大量终端频繁的进行切换。因此,NTN场景下,如何管理大量终端的切换是需要解决的问题。In Non-Terrestrial Networks (NTN) scenarios, satellite movement will lead to frequent service link and feeder link switching, resulting in all terminals in the NTN cell needing to switch frequently. Execute cell handover process. In addition, because the coverage area of NTN cell services is larger than that of terrestrial network (Terrestrial Networks, TN) cells, the number of terminals served will be greater, and the movement of satellites will also cause a large number of terminals to switch frequently. Therefore, in NTN scenarios, how to manage the switching of a large number of terminals is a problem that needs to be solved.

NTN简介:Introduction to NTN:
典型的NTN部署场景如下:在版本17(Release 17,R17)中,终端、基站以及核心网设备均部署在地面上,终端和网络设备之间的通信数据经由空中卫星进行中转。相对于地面通信(Terrestrial Networks,TN)系统,基于卫星的非地面通信系统具有更为广阔的覆盖范围,并且NTN小区服务的用户数量也会远大于TN小区。Typical NTN deployment scenarios are as follows: In version 17 (Release 17, R17), terminals, base stations and core network equipment are all deployed on the ground, and communication data between terminals and network equipment are relayed via air satellites. Compared with terrestrial communications (Terrestrial Networks, TN) systems, satellite-based non-terrestrial communications systems have wider coverage, and the number of users served by NTN cells will be much larger than that of TN cells.
如图1b所示,UE和卫星之间的链路称为服务链路(即service link),卫星和基站之间的链路称为馈线链路(即feeder link)。在某些场景下(如低轨卫星(Low Earth Orbit Satellite,LEO)),由于卫星移动,会发生service link和/或feeder link的切换。对于service link切换,小区内的所有UE的服务卫星需要从一颗卫星切换为另外一颗卫星。对于feeder link切换,某一卫星需要从一个网关(或基站)切换到另外一个网关(或基站)。在R17版本中,无论是service link切换还是feeder link切换场景,对于NTN小区的所有UE来说,都需要执行小区切换过程。As shown in Figure 1b, the link between the UE and the satellite is called the service link, and the link between the satellite and the base station is called the feeder link. In some scenarios (such as Low Earth Orbit Satellite (LEO)), service link and/or feeder link switching will occur due to satellite movement. For service link handover, the serving satellites of all UEs in the cell need to be switched from one satellite to another satellite. For feeder link switching, a certain satellite needs to switch from one gateway (or base station) to another gateway (or base station). In the R17 version, whether it is service link switching or feeder link switching scenario, all UEs in the NTN cell need to perform the cell switching process.
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的小区切换方法进行详细地说明。The cell switching method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through some embodiments and application scenarios.

That is to say, if the cell provides resource location information for monitoring the first group of identifiers, the first cell can be implicitly instructed to use the first group of identifiers to schedule the handover assistance information. For example, the system message block (such as SIB1) of the first cell indicates that the first cell will use the first group of identifiers to schedule the handover assistance information. In addition, a resource location for monitoring the first group of identifiers is provided. information, the terminal in the first cell will listen to the first group of identifiers at the resource location represented by the resource location information to receive handover assistance information.
