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连接管理方法进行详细地说明。The connection management 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.
本申请各实施例针对接入层(Access Stratum，AS)安全未被激活的用户设备(User Equipment，UE)在发生服务链路(service link)，和/或，馈线链路(feeder link)切换的时候，如何进行连接管理的问题，提供一种解决方案，能够使得在获知源服务小区停止服务信息的情况下，处于连接态且AS安全未被激活的UE通过执行退回空闲态和/或保持连接态的操作，明确了UE在发生service link和/或feeder link switch的时候的连接管理行为。为了便于更加清晰地理解本申请各实施例，首先对一些相关的技术知识进行如下介绍。Each embodiment of the present application is aimed at user equipment (User Equipment, UE) whose access layer (Access Stratum, AS) security has not been activated when service link (service link) and/or feeder link (feeder link) switching occurs. When the problem of how to perform connection management is provided, a solution is provided that enables the UE in the connected state and the AS security has not been activated to return to the idle state and/or maintain the The operation of the connection state clarifies the connection management behavior of the UE when service link and/or feeder link switch occurs. In order to facilitate a clearer understanding of each embodiment of the present application, some relevant technical knowledge is first introduced as follows.
一、NTN(Non-terrestrial networks，非地面网络)1. NTN (Non-terrestrial networks, non-terrestrial networks)
图2是本申请实施例可应用的非地面网络的示意图，如图2所示，典型的NTN部署场景包括终端(也可以称为用户设备(User Equipment，UE))21、卫星(Satellite)(或无人空中***平台(Unmanned Aerial System platform，UAS platform))22和网关(Gateway)(或基站)23。在R17版本中，终端21、基站23以及核心网设备均部署在地面上，终端21和基站23之间的通信数据经由空中的卫星22进行中转。相对于地面网络(Terrestrial Networks，TN)***，基于卫星的非地面通信***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。Figure 2 is a schematic diagram of a non-terrestrial network applicable to the embodiment of the present application. As shown in Figure 2, a typical NTN deployment scenario includes terminals (also called user equipment (User Equipment, UE)) 21, satellites (Satellite) ( Or Unmanned Aerial System platform (UAS platform) 22 and Gateway (or base station) 23. In the R17 version, the terminal 21, the base station 23 and the core network equipment are all deployed on the ground, and the communication data between the terminal 21 and the base station 23 is relayed via the satellite 22 in the sky. Compared with terrestrial network (Terrestrial Networks, TN) systems, satellite-based non-terrestrial communication systems have wider coverage, and the number of users served by NTN cells will be much larger than that of TN cells.
如图2所示，终端21和卫星22之间的链路称为服务链路(即service link)，卫星22和网关(或基站)23之间的链路称为馈线链路(即feeder link)，终端21处于卫星所覆盖的卫星视场或无人空中***平台(Field of view the satellite or UAS platform),卫星视场包括多个波束覆盖范围(Beam footprint)。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，小区内的所有终端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小区的所有终端来说，都需要执行小区切换过程。As shown in Figure 2, the link between the terminal 21 and the satellite 22 is called a service link, and the link between the satellite 22 and the gateway (or base station) 23 is called a feeder link. ), the terminal 21 is in the field of view of the satellite or unmanned aerial system platform (Field of view the satellite or UAS platform) covered by the satellite, and the satellite field of view includes multiple beam coverage areas (Beam footprint). 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 switching, the service satellites of all terminals in the community 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, regardless of the service link switching or feeder link switching scenario, all terminals in the NTN community need to perform the cell switching process.
本申请实施例提供的连接管理方法，可应用于NTN场景中，在获知源服务小区停止服务信息的情况下，处于连接态且接入层AS安全未被激活的用户设备UE通过执行退回空闲态和/或保持连接态的操作，明确了UE在发生service link和/或feeder link switch的时候的连接管理行为。The connection management method provided by the embodiment of the present application can be applied to the NTN scenario. When the source serving cell stops service information, the user equipment UE that is in the connected state and the access layer AS security has not been activated returns to the idle state by executing And/or the operation of maintaining the connected state clarifies the connection management behavior of the UE when service link and/or feeder link switch occurs.
图3是本申请实施例提供的连接管理方法的流程示意图之一，如图3所示，该方法包括步骤301；其中：Figure 3 is one of the flow diagrams of the connection management method provided by the embodiment of the present application. As shown in Figure 3, the method includes step 301; wherein:
步骤301、在获知源服务小区停止服务信息的情况下，处于连接态的用户设备UE执行以下任意一项连接管理操作：Step 301: After learning that the source serving cell has stopped serving information, the user equipment UE in the connected state performs any one of the following connection management operations:
所述UE退回空闲态；The UE returns to the idle state;
所述UE保持连接态； The UE remains connected;
其中，所述UE的接入层AS安全未被激活。Wherein, the access layer AS security of the UE is not activated.
需要说明的是，本申请实施例可应用于NTN场景中，用户设备(也可以称为终端)包括但不限于上述所列举的终端11的类型，目标网络侧设备包括但不限于上述所列举的网络侧设备12的类型，本申请实施例对此并不限定。It should be noted that the embodiments of the present application can be applied in NTN scenarios. User equipment (may also be called a terminal) includes but is not limited to the types of terminal 11 listed above, and target network side equipment includes but is not limited to the types listed above. The type of the network side device 12 is not limited in the embodiment of this application.
具体地，源服务小区停止服务信息包括源服务小区停止服务或源服务小区将要停止服务；可以理解的是，AS安全还未激活的UE可以在源服务小区停止服务之前获知源服务小区停止服务或源服务小区将要停止服务，也可以在源服务小区停止服务之后获知源服务小区停止服务。Specifically, the source serving cell stops serving information includes the source serving cell stops serving or the source serving cell is about to stop serving; it can be understood that the UE whose AS security has not been activated can learn that the source serving cell stops serving or the source serving cell stops serving. The source serving cell is about to stop serving, or it can be learned that the source serving cell stops serving after the source serving cell stops serving.
在获知源服务小区停止服务或将要停止服务的情况下，处于连接态的UE可以执行以下任意一项连接管理操作：UE退回空闲态；UE保持连接态；其中，UE退回空闲态包括UE在获知源服务小区停止服务信息之后，UE主动退回空闲态，例如，在获知源服务小区将要停止服务的情况下，对于AS安全还未激活的UE，UE主动退回空闲态；UE保持连接态包括UE在获知源服务小区停止服务信息之后，UE仍然保持连接态，例如，在获知源服务小区停止服务的情况下，对于AS安全还未激活的UE，UE仍然保持连接态。After learning that the source serving cell has stopped serving or is about to stop serving, the UE in the connected state can perform any of the following connection management operations: the UE returns to the idle state; the UE remains connected; where the UE returns to the idle state includes the UE being informed that the source serving cell has stopped serving or is about to stop serving. After the source serving cell stops serving information, the UE actively returns to the idle state. For example, when it is learned that the source serving cell is about to stop serving, for a UE whose AS security has not been activated, the UE actively returns to the idle state; the UE remaining connected state includes the UE being in the idle state. After learning that the source serving cell has stopped serving information, the UE still remains connected. For example, after learning that the source serving cell has stopped serving, for a UE whose AS security has not been activated, the UE still remains connected.
需要说明的是，在终端获知源服务小区停止服务信息的情况下，终端可以在源小区停止服务时或者在源服务小区将要停止服务时或者在源小区停止服务前的预设时间时执行以下任意一项连接管理操作：UE退回空闲态；UE保持连接态。另外，需要说明的是，终端可以认为在源服务小区停止服务前的预设时间内为源服务小区将要停止服务。示例性的，源服务小区在T1时间停止服务，在[T1-t，T1]时间范围内，终端认为源服务小区将要停止服务。其中，上述的t可以是基于终端实现设置的，也可以是网络配置的。在后续实施例中，对源服务小区将要停止服务的理解同上述描述，将不再赘述。It should be noted that when the terminal learns the information that the source serving cell has stopped serving, the terminal can perform any of the following when the source cell stops serving, when the source serving cell is about to stop serving, or at the preset time before the source cell stops serving. A connection management operation: UE returns to idle state; UE remains connected. In addition, it should be noted that the terminal may consider that the source serving cell will stop serving the service within a preset time before the source serving cell stops serving. For example, the source serving cell stops serving at time T1. Within the time range [T1-t, T1], the terminal believes that the source serving cell will stop serving. Among them, the above t may be set based on terminal implementation or may be configured by the network. In subsequent embodiments, the understanding that the source serving cell will stop serving is the same as the above description, and will not be described again.
本申请实施例提供的连接管理方法中，在获知源服务小区停止服务信息的情况下，处于连接态且接入层AS安全未被激活的用户设备UE通过执行退回空闲态和/或保持连接态的操作，明确了UE在发生service link和/或feeder link switch的时候的连接管理行为。In the connection management method provided by the embodiment of the present application, when the source serving cell stops service information, the user equipment UE that is in the connected state and the access layer AS security has not been activated returns to the idle state and/or maintains the connected state by executing The operation clarifies the UE's connection management behavior when service link and/or feeder link switch occurs.
可选地，所述获知源服务小区停止服务信息包括以下至少一项：Optionally, the obtaining the source serving cell out of service information includes at least one of the following:
1)所述UE基于所述源服务小区提供的切换辅助信息获知；其中，所述切换辅助信息包含所述源服务小区的UE需要执行切换过程的时间信息。1) The UE learns based on the handover auxiliary information provided by the source serving cell; wherein the handover auxiliary information includes the time information that the UE of the source serving cell needs to perform the handover process.
具体地，源服务小区向UE提供切换辅助信息，切换辅助信息包含源服务小区的UE需要执行切换过程的时间信息，例如，基于时间的切换触发事件信息(time event)，则UE可以根据源服务小区提供的时间信息判定或预估源服务小区停止服务或将要停止服务的时机，以获知源服务小区停止服务信息。示例性的，基于时间的切换触发事件信息为[t1，t2]，相当于在[t1，t2]时间范围内终端需要与目标小区建立连接，则终端可认为在t1时，源服务小区会停止服务或者将要停止服务。Specifically, the source serving cell provides handover auxiliary information to the UE. The handover auxiliary information includes the time information that the UE of the source serving cell needs to perform the handover process. For example, time-based handover trigger event information (time event), then the UE can perform the handover process according to the source serving cell. The time information provided by the cell determines or estimates the timing when the source serving cell stops serving or is about to stop serving, so as to obtain the source serving cell stopping service information. For example, the time-based handover trigger event information is [t1, t2], which means that the terminal needs to establish a connection with the target cell within the time range of [t1, t2]. The terminal can consider that at t1, the source serving cell will stop service or will cease service.
需要说明的是，切换辅助信息除了包含源服务小区的UE需要执行切换过程的时间信息之外，还包括目标小区配置信息；切换辅助信息是源服务网络侧设备通过广播或组播提供的，切换辅助信息用于辅助源服务小区内的一个或多个UE从源服务小区切换到目标小区，源服务小区为源服务网络侧设备管理的小区。例如，在源服务小区内的UE在发生service link和/或feeder link switch时，UE可以基于切换辅助信息执行切换过程。It should be noted that, in addition to the time information that the UE of the source serving cell needs to perform the handover process, the handover auxiliary information also includes the target cell configuration information; the handover auxiliary information is provided by the source serving network side device through broadcast or multicast. The auxiliary information is used to assist one or more UEs in the source serving cell to switch from the source serving cell to the target cell. The source serving cell is a cell managed by the source serving network side device. For example, when a service link and/or feeder link switch occurs for a UE in the source serving cell, the UE can perform the handover process based on the handover assistance information.
2)所述UE基于服务卫星和/或邻近卫星的星历信息获知。2) The UE learns based on the ephemeris information of the serving satellite and/or neighboring satellites.
具体地，UE可以基于服务卫星和/或邻近卫星的星历信息判定或预估源服务小区停止 服务或将要停止服务，从而获知源服务小区停止服务信息。例如，UE基于该UE的服务卫星和/或邻近卫星的星历信息判定或预估源服务小区停止服务或将要停止服务的时机，以获知源服务小区停止服务信息。具体地，终端可以基于服务卫星和/或邻近卫星的星历信息判定或者预估特定区域的覆盖情况，例如，特定区域会被哪颗卫星覆盖，由此预判源服务小区的停止服务时机或者源服务小区是否将要停止服务。Specifically, the UE may determine or estimate that the source serving cell will stop based on the ephemeris information of the serving satellite and/or neighboring satellites. The service may be out of service, so as to obtain the out of service information of the source serving cell. For example, the UE determines or estimates the timing when the source serving cell stops serving or is about to stop serving based on the ephemeris information of the UE's serving satellite and/or neighboring satellites, so as to obtain the source serving cell stopping service information. Specifically, the terminal can determine or predict the coverage of a specific area based on the ephemeris information of the serving satellite and/or neighboring satellites, for example, which satellite will cover the specific area, thereby predicting the timing of stopping service of the source serving cell or Whether the source serving cell will stop serving.
3)所述UE基于源服务小区提供的停止服务时间参数获知；3) The UE learns based on the out-of-service time parameters provided by the source serving cell;
具体地，源服务小区可提供源服务小区停止服务的时间参数(如通过t-service参数)，终端基于该时间参数获知源服务小区停止服务的时机。其中，上述时间参数可以是通过***消息提供的。Specifically, the source serving cell may provide a time parameter for the source serving cell to stop service (for example, through the t-service parameter), and the terminal learns the timing for the source serving cell to stop service based on the time parameter. Wherein, the above time parameters may be provided through system messages.
4)所述UE基于第一指示信息获知；其中，所述第一指示信息用于指示执行切换过程。4) The UE learns based on the first indication information; wherein the first indication information is used to instruct execution of the handover process.
具体地，UE接收源服务网络侧设备发送的第一指示信息，则UE可以基于第一指示信息获知源服务小区停止服务或将要停止服务，从而获知源服务小区停止服务信息。Specifically, if the UE receives the first indication information sent by the source serving network side device, the UE can learn that the source serving cell has stopped serving or is about to stop serving based on the first indication information, thereby learning the source serving cell stopping service information.
可选地，所述第一指示信息是通过组标识调度的。Optionally, the first indication information is scheduled through a group identifier.
实际中，UE的源服务网络侧设备向UE发送的第一指示信息可以包括以下至少一项：In practice, the first indication information sent to the UE by the source serving network side device of the UE may include at least one of the following:
a)指示服务链路service link切换的信息；a) Information indicating service link switching;
b)指示service link切换的切换时机的信息；b) Information indicating the switching timing of service link switching;
c)指示馈线链路feeder link切换的信息；c) Information indicating feeder link switching;
d)指示馈线链路feeder link切换的切换时机的信息；d) Information indicating the switching timing of feeder link switching;
e)指示源服务小区停止服务的信息；e) Information instructing the source serving cell to stop serving;
f)指示源服务小区停止服务时机的信息；f) Information indicating the timing for the source serving cell to stop serving;
g)指示所述UE执行切换的信息。g) Information instructing the UE to perform handover.
需要说明的是，第一指示信息是UE的源服务网络侧设备在源服务小区将要停止服务的情况下发送的。示例性的，源服务网络侧设备可以通过组标识调度第一指示信息。在接收到第一指示信息的情况下，源服务小区内的UE(如AS安全激活的终端)需要执行切过程，对于源服务小区中AS安全未激活的终端可认为源服务小区将要停止服务，因此，AS安全未激活的终端执行以下任意一项连接管理操作：UE主动退回空闲态；UE继续保持连接态。It should be noted that the first indication information is sent by the source serving network side device of the UE when the source serving cell is about to stop serving. For example, the source serving network side device may schedule the first indication information through the group identifier. Upon receiving the first indication information, the UE in the source serving cell (such as a terminal with AS security activated) needs to perform a handover process. For terminals with inactive AS security in the source serving cell, it can be considered that the source serving cell is about to stop serving.
