背景技术Background technique
在5G新无线(New Radio,NR)系统中,终端设备(User Equipment,UE)可以在室内小基站和室外宏站(Macro Base Station)之间进行小区切换。也就是说,终端设备可以从室内小基站切换到室外宏站,也可以从室外宏站切换到室内小基站。In the 5G New Radio (New Radio, NR) system, a terminal device (User Equipment, UE) can perform cell handover between an indoor small base station and an outdoor macro base station (Macro Base Station). That is to say, the terminal device can be handed over from an indoor small base station to an outdoor macro base station, or from an outdoor macro base station to an indoor small base station.
目前,基站切换可以通过条件切换(Conditional Handover,CHO)的方法来实现。在目前的CHO中,源基站根据UE上报的测量结果来确定CHO的候选小区,并且源基站会向所有的候选小区发送CHO请求来请求所有的候选小区来配置候选小区的无线侧配置和CHO的执行条件。所述UE的测量结果根据基站配置的测量事件进行。所述测量时间一般指的是A3事件,该A3事件指的是邻小区的偏移量超过终端设备所连接的小区(即源基站的小区),其中,该邻小区与终端设备所连接的小区可以属于不同的基站。Currently, base station handover can be implemented by a conditional handover (Conditional Handover, CHO) method. In the current CHO, the source base station determines the candidate cells for CHO according to the measurement results reported by the UE, and the source base station will send a CHO request to all candidate cells to request all candidate cells to configure the wireless side configuration of the candidate cells and the CHO configuration. execution conditions. The measurement result of the UE is performed according to the measurement event configured by the base station. The measurement time generally refers to the A3 event, and the A3 event refers to the fact that the offset of the neighboring cell exceeds the cell to which the terminal device is connected (ie, the cell of the source base station), wherein the neighboring cell and the cell to which the terminal device is connected Can belong to different base stations.
如何为终端设备确定在进行条件切换时的候选小区成为研究的热点问题。How to determine a candidate cell for a terminal device when performing a conditional handover has become a hot research issue.

为了能够更好地理解本申请实施例,下面对本申请实施例涉及的专业术语进行介绍:In order to better understand the embodiments of the present application, the following introduces the technical terms involved in the embodiments of the present application:
条件切换(Conditional Handover,CHO)是让终端设备来根据测量结果选择目标基站并发起切换执行过程。终端设备可以向目标小区发起随机接入过程。这样可以避免在终端设备和源基站进行信令交互,以及源基站和目标基站进行信令交互的时间内,由于无线链路状态变化导致的终端设备进行小区切换失败的情况发生。通过这种方式,CHO提高了用户切换过程中的鲁棒性。The conditional handover (Conditional Handover, CHO) is to let the terminal equipment select the target base station according to the measurement result and initiate the handover execution process. The terminal device can initiate a random access procedure to the target cell. This can avoid the failure of the terminal device to perform cell handover due to the change of the radio link state during the signaling interaction between the terminal device and the source base station and the signaling interaction between the source base station and the target base station. In this way, CHO improves the robustness during user switching.
接入和移动性管理功能(Access and Mobility Management Function,AMF)是5G核心网(5GC)的主要功能单元,可以完成终端设备的接入和移动性管理,相当于移动管理实体(Mobility Management Entity,MME)的一部分功能。The Access and Mobility Management Function (AMF) is the main functional unit of the 5G core network (5GC), which can complete the access and mobility management of terminal equipment, which is equivalent to the Mobility Management Entity (Mobility Management Entity, Part of the function of MME).

It is responsible for processing user services. It can be regarded as the bearer management part of the MME, the serving gateway (Serving GateWay, SGW) and the PDN gateway (PDN GateWay, PGW).

In the ANR function, there are both the neighbor detection function and the neighbor deletion function. Among them, the neighbor cell detection function is used to find the neighbor cell and add the neighbor cell to the neighbor cell relationship list, the neighbor cell deletion function is used to delete the outdated neighbor cell relationship; the neighbor cell deletion function is an internal behavior of the base station, The neighboring cell detection function needs to be completed through interaction between the base station and the terminal equipment. In practical applications, the ANR function realizes the addition and management of the neighbor cell relationship by detecting and reporting the global cell identifier (Cell Global Identifier, CGI) of the target cell.

Figure 3 takes the second network element handover from an indoor small base station to an outdoor macro base station as an example, and the target cell may be a serving cell of the outdoor macro base station. The number of outdoor macro stations may be one or more, which is not limited in this embodiment of the present application. In FIG. 3 , the second network element sends a measurement report related to the target cell to the indoor small base station. The measurement report includes the physical cell identifier (Physical Cell Identifier, PCI) of the target cell, but the measurement report does not include CGI.

The solution of this application is aimed at the indoor-to-outdoor or outdoor-to-indoor cell handover scenario. In this type of scenario, the cells where the second network element performs cell handover are usually fewer and relatively fixed. For example, the second network element may switch from an indoor small base station to a specific outdoor macro base station, or from an outdoor macro base station to a specific indoor small base station. It is not necessary to use cells that cover the vicinity of the room as cells in the candidate cell list, but the network side determines the candidate cells according to specific parameters. Through this method, the number of selected cells during conditional handover is reduced, and the signaling overhead of the Xn interface is also reduced.
