技术领域Technical field
本申请涉及通信技术领域,尤其涉及一种小区标识的更新方法与装置。The present application relates to the field of communication technology, and in particular, to a method and device for updating a cell identity.
背景技术Background technique
随着通信技术的发展,中继设备得以广泛应用。在第五代(the fifthgeneration,5G)移动通信系统新无线(new radio,NR)研究中,提出了集成无线接入链路和无线回传链路的接入回传一体化(integrated access and backhaul,IAB)的节点。IAB节点通过无线接口以类似终端的方式接入一个服务于它的基站,该基站称为宿主基站(donorbase station),IAB节点和宿主基站之间的无线接口链路称为回传链路(backhaul link)。IAB节点对接入其小区的终端提供与普通基站类似的功能和服务,IAB节点与终端之间的通信链路称之为接入链路(access link)。With the development of communication technology, relay equipment has been widely used. In the research on new radio (NR) of the fifth generation (5G) mobile communication system, the integrated access and backhaul integration of wireless access link and wireless backhaul link is proposed. ,IAB) node. The IAB node accesses a base station serving it through a wireless interface in a terminal-like manner. The base station is called the donor base station. The wireless interface link between the IAB node and the donor base station is called the backhaul link. link). The IAB node provides similar functions and services to ordinary base stations for terminals accessing its cell. The communication link between the IAB node and the terminal is called an access link.
通常,IAB节点可以部署在室外、室内等不易部署有线传输网络的场景下,一般固定在地面上或者楼宇中,不具备移动性。现有的定位方案中,终端设备接入固定位置的IAB节点,网络可以根据终端设备向网络发送的上行定位消息(UL positioning message),以及该IAB节点的小区信息来确定终端设备的位置。其中,上行定位消息包含终端设备基于哪个小区所做的测量结果以及小区标识。Generally, IAB nodes can be deployed outdoors or indoors in scenarios where it is difficult to deploy a wired transmission network. They are generally fixed on the ground or in buildings and are not mobile. In the existing positioning solution, the terminal device accesses an IAB node at a fixed location, and the network can determine the location of the terminal device based on the uplink positioning message (UL positioning message) sent by the terminal device to the network and the cell information of the IAB node. The uplink positioning message includes the measurement results of the cell based on which the terminal equipment is based and the cell identity.
然而,随着移动中继的普遍应用,例如,移动中继搭载在车辆上的车载中继(vehicle mounted relay,VMR),使得位于车辆内部或周围的终端设备可以通过移动中继实现入网,VMR节点可以理解为具有移动能力的IAB节点。基于现有定位方案,虽然终端设备可以使用VMR节点的小区信号进行定位测量,但是VMR节点的小区位置在不断发生变化,小区标识也在不断发生变化,网络不能及时获知更新后的小区标识。However, with the widespread application of mobile relays, for example, vehicle mounted relays (VMR) where mobile relays are mounted on vehicles, terminal devices located in or around the vehicle can access the network through mobile relays. VMR Nodes can be understood as IAB nodes with mobile capabilities. Based on the existing positioning solution, although terminal equipment can use the cell signal of the VMR node for positioning measurements, the cell location of the VMR node is constantly changing, and the cell identity is also constantly changing, and the network cannot learn the updated cell identity in time.

步骤301.IAB节点通过MT功能与服务IAB节点的无线接入网(radio accessnetwork,RAN)建立RRC连接。Step 301. The IAB node establishes an RRC connection with the radio access network (radio access network, RAN) serving the IAB node through the MT function.
具体地,IAB MT进行小区选择,选择合适的小区完成RRC连接建立后,通过RRCSetup Complete消息向网络指示其具有移动能力(也即,指示其为IAB节点),并通过服务IAB MT的RAN发送注册请求消息。上述过程中,IAB节点的初始接入与常规UE相同。Specifically, the IAB MT performs cell selection, selects a suitable cell to complete the RRC connection establishment, and then indicates to the network that it has mobility capability (that is, indicates that it is an IAB node) through an RRCSetup Complete message, and sends a registration request message through the RAN serving the IAB MT. In the above process, the initial access of the IAB node is the same as that of a regular UE.
步骤302.RAN通过N2消息将注册请求消息发送至5G核心网,同时在N2消息中指示注册网络的是IAB节点,网络将对该IAB节点进行身份验证。Step 302. The RAN sends the registration request message to the 5G core network through the N2 message. At the same time, the N2 message indicates that the IAB node is registering the network, and the network will authenticate the IAB node.
步骤303.IAB MT完成注册流程,成功注册到网络中。Step 303. IAB MT completes the registration process and successfully registers into the network.
步骤304.IAB MT发起会话建立,网络给IAB MT分配互联网协议IP地址,IAB MT使用该IP地址与操作管理和维护(operation administration and maintenance,OAM)进行交互。Step 304: The IAB MT initiates session establishment, and the network allocates an Internet Protocol IP address to the IAB MT. The IAB MT uses the IP address to interact with operation administration and maintenance (OAM).
步骤305.OAM给IAB节点配置小区信息。小区信息包括如小区标识、跟踪区域码(tracking area code,TAC)等。Step 305. OAM configures cell information for the IAB node. Cell information includes, for example, cell identity, tracking area code (TAC), etc.

上述步骤306至步骤308为IAB节点的F1建立流程。The above steps 306 to 308 are the F1 establishment process of the IAB node.
上述通信过程,IAB节点通常为地面上固定不动的中继设备。现有的5G定位方案中,UE向网络发送上行定位消息(UL positioning message),该上行定位消息包含了测量结果,测量结果包含了小区标识,网络(如位置管理服务LMF网元)基于小区标识可以确定UE是基于哪个小区做的测量。进一步地,网络根据该小区的位置以及测量结果确定UE的位置。可以理解为,现有的小区都是固定的,网络可以提前获知小区的地理位置信息,结合UE上报的测量结果对UE进行定位。In the above communication process, the IAB node is usually a fixed relay device on the ground. In the existing 5G positioning solution, the UE sends an uplink positioning message (UL positioning message) to the network. The uplink positioning message contains the measurement results. The measurement results include the cell identity. The network (such as the location management service LMF network element) based on the cell identity It can be determined on which cell the UE performs measurements. Further, the network determines the location of the UE based on the location of the cell and the measurement results. It can be understood that the existing cells are all fixed, and the network can learn the geographical location information of the cell in advance and position the UE based on the measurement results reported by the UE.
然而,如果UE接入的小区是移动基站中继(mobile base station relay,MBSR),MBSR又称为VMR或者mobile IAB,该小区处于移动状态,那么当UE使用MBSR的小区信号执行定位测量,网络需要获知MBSR小区的位置,才能准确地计算UE的位置信息。参见图4,图4是包含MBSR的通信系统示意图。如图4所示,用户携带智能终端乘坐一车辆,车辆上安装的MBSR可以向车内用户提供5G接入服务,随着车辆的移动,MBSR小区的位置不断变化,虽然用户携带的智能终端可以使用MBSR小区信号进行定位测量,但是网络并不知道该小区当前的位置。However, if the cell that the UE accesses is a mobile base station relay (MBSR), MBSR is also called VMR or mobile IAB, and the cell is in a mobile state, then when the UE uses the MBSR cell signal to perform positioning measurements, the network The location of the MBSR cell needs to be known to accurately calculate the location information of the UE. Refer to Figure 4, which is a schematic diagram of a communication system including MBSR. As shown in Figure 4, a user carries a smart terminal and rides in a vehicle. The MBSR installed on the vehicle can provide 5G access services to users in the vehicle. As the vehicle moves, the location of the MBSR cell continues to change. Although the smart terminal carried by the user can The MBSR cell signal is used for positioning measurement, but the network does not know the current location of the cell.
对此,网络还需要对MBSR发起定位,以获取MBSR的小区位置。参见图5,图5是本申请实施例提供的MBSR小区的定位流程的示意图。如图5所示,该定位流程包括:In this regard, the network also needs to initiate positioning on the MBSR to obtain the cell location of the MBSR. Referring to Figure 5, Figure 5 is a schematic diagram of the positioning process of an MBSR cell provided by an embodiment of the present application. As shown in Figure 5, the positioning process includes:
步骤500.LMF网元通过发送接收点(transmission-reception point,TRP)信息交互流程,获知某个小区标识对应的小区是否是移动的小区。步骤500,可以包括:Step 500.

Optionally, the F1 TRP information response includes the cell identity of the MBSR.
步骤500D.宿主基站向LMF网元发送NRPPa TRP信息响应(NRPPa TRP informationresponse),NRPPa TRP信息响应包括移动性指示。可选地,NRPPa TRP信息响应包括MBSR的小区标识。Step 500D. The host base station sends an NRPPa TRP information response (NRPPa TRP information response) to the LMF network element, where the NRPPa TRP information response includes a mobility indication. Optionally, the NRPPa TRP information response includes the cell identity of the MBSR.
步骤501.当网络需要对某个UE发起定位流程时,接入和移动性管理功能AMF网元触发对该UE发起定位。Step 501. When the network needs to initiate a positioning process for a certain UE, the access and mobility management function AMF network element triggers the positioning process for the UE.
步骤502.AMF网元向LMF网元发送定位请求,如发送Nlmf_Location_Determinelocation Request,定位请求用于请求LMF网元对UE发起定位。Step 502. The AMF network element sends a positioning request to the LMF network element, such as sending Nlmf_Location_Determinelocation Request. The positioning request is used to request the LMF network element to initiate positioning for the UE.
步骤503.执行现有的定位流程。具体地,当UE使用MBSR的小区信号执行定位测量,UE会在上行定位消息中携带定位测量数据,其中定位测量数据中包含小区标识(cell ID)。Step 503. Execute the existing positioning process. Specifically, when the UE uses the MBSR cell signal to perform positioning measurement, the UE will carry the positioning measurement data in the uplink positioning message, where the positioning measurement data includes the cell identification (cell ID).
可选地,若步骤500D中F1 TRP信息响应的小区标识与UE上报的定位测量数据中包含小区标识相同,LMF网元可获知定位测量数据中包含的小区标识对应的小区具有移动性,LMF网元可执行如下步骤:Optionally, if the cell identity responded to by the F1 TRP information in step 500D is the same as the cell identity contained in the positioning measurement data reported by the UE, the LMF network element can learn that the cell corresponding to the cell identity contained in the positioning measurement data has mobility, and the LMF network You can perform the following steps:
步骤504A.LMF网元向宿主基站发送小区位置请求,如发送NRPPa TRP信息请求,NRPPa TRP信息请求包括MBSR的小区标识。Step 504A. The LMF network element sends a cell location request to the host base station, such as sending an NRPPa TRP information request. The NRPPa TRP information request includes the cell identity of the MBSR.
步骤504B.宿主基站向MBSR发送小区位置请求,如发送F1 TRP信息请求,该F1 TRP信息请求包括MBSR的小区标识。Step 504B. The host base station sends a cell location request to the MBSR, such as sending an F1 TRP information request. The F1 TRP information request includes the cell identity of the MBSR.
步骤504C.MBSR向宿主基站发送小区位置响应,如发送F1 TRP信息响应,该F1 TRP信息响应包括MBSR的小区标识对应的小区的位置信息。Step 504C. MBSR sends a cell location response, such as an F1 TRP information response, to the host base station. The F1 TRP information response includes the location information of the cell corresponding to the cell identity of the MBSR.
步骤504D.宿主基站向LMF网元发送小区位置响应,如发送NRPPa TRP信息响应,该NRPPa TRP信息响应包括MBSR的小区标识对应的小区的位置信息。Step 504D. The host base station sends a cell location response to the LMF network element, such as sending an NRPPa TRP information response. The NRPPa TRP information response includes the location information of the cell corresponding to the cell identifier of the MBSR.
基于步骤504A至步骤504D,LMF网元可获知移动小区最新的位置信息。Based on steps 504A to 504D, the LMF network element can obtain the latest location information of the mobile cell.
步骤505.LMF网元向AMF网元发送定位响应,定位响应包括UE的位置。Step 505. The LMF network element sends a positioning response to the AMF network element, where the positioning response includes the location of the UE.
具体地,LMF网元根据步骤503中UE上报的定位测量数据,以及步骤504D中MBSR的小区标识对应的小区的位置信息,确定UE的位置。Specifically, the LMF network element determines the location of the UE based on the positioning measurement data reported by the UE in step 503 and the location information of the cell corresponding to the cell identifier of the MBSR in step 504D.
基于图5描述的定位流程可知,MBSR在移动过程中,同一个MBSR广播的小区标识可能发生改变,这样就导致一个问题:UE的上行定位消息中包含的MBSR的小区标识可能与LMF网元保存的MBSR的小区标识(即,通过上述步骤500获知的MBSR的小区标识)不同,一旦MBSR改变了小区标识,LMF网元保存的MBSR的小区标识就会无效,从而导致基于LMF网元保存的MBSR的小区标识,通过步骤504A至步骤504D的流程,获取的小区位置信息不准确。示例性地,步骤500中,MBSR的小区标识为Cell ID#1,MBSR在移动过程中,小区标识从Cell ID#1改变成Cell ID#2。此时,如果UE使用MBSR的小区信号执行定位测量时,UE会在上行定位消息中携带定位测量数据,其中定位测量数据中包含的小区标识为Cell ID#2,这样LMF在接收到Cell ID#2之后,就无法判断出该Cell ID#2对应的小区是否是移动性的。由于LMF只保存了Cell ID#1对应的小区具有移动性,那么LMF此时就不会发起步骤504A至步骤504D的流程。由于LMF没有获取的MBSR的小区位置信息,LMF只根据上行定位消息中携带的定位测量数据计算的UE位置信息是不准确的。可见,导致UE定位结果不佳的主要原因是:目前MBSR的小区标识发生改变,网络并不知道其最新的小区标识。Based on the positioning process described in Figure 5, it can be seen that during the movement of the MBSR, the cell identity broadcast by the same MBSR may change, which leads to a problem: the cell identity of the MBSR contained in the UE's uplink positioning message may be stored with the LMF network element. The cell identity of the MBSR (that is, the cell identity of the MBSR learned through the above step 500) is different. Once the MBSR changes the cell identity, the cell identity of the MBSR saved by the LMF network element will be invalid, resulting in a situation based on the MBSR saved by the LMF network element. The cell location information obtained through the process from step 504A to step 504D is inaccurate. For example, in step 500, the cell identity of MBSR is Cell ID#1. During the movement of MBSR, the cell identity changes from Cell ID#1 to Cell ID#2. At this time, if the UE uses the MBSR cell signal to perform positioning measurement, the UE will carry the positioning measurement data in the uplink positioning message, and the cell identifier contained in the positioning measurement data is Cell ID#2, so that the LMF receives Cell ID# 2, it is impossible to determine whether the cell corresponding to Cell ID#2 is mobile. Since the LMF only saves that the cell corresponding to Cell ID #1 has mobility, the LMF will not initiate the process from step 504A to step 504D at this time. Since the LMF has not obtained the cell location information of the MBSR, the UE location information calculated by the LMF only based on the positioning measurement data carried in the uplink positioning message is inaccurate. It can be seen that the main reason for poor UE positioning results is that the current cell identity of MBSR has changed, and the network does not know its latest cell identity.
基于上述问题,本申请实施例提出一种小区标识的更新方法,当网络获知某个小区是移动小区,可以触发向该小区对应的MBSR订阅小区标识更新事件,以便及时获知MBSR广播的最新的小区标识。执行上述订阅流程的网元可以是LMF网元或AMF网元,对此本申请实施例不作限定。此外,还可以在F1建立(F1 setup)流程中,MBSR向服务MBSR的宿主基站发送MBSR标识,宿主基站将该MBSR小区的信息(包括MBSR标识、小区标识以及移动性指示)发送至核心网的网络存储功能NRF网元,当MBSR小区的信息发生改变时,NRF存储的该信息会相应更新,从而保证网络获取的某个MBSR的小区标识是最新的。综上,上述任一方案都能够确保网络及时获知MBSR广播的最新的小区标识,进而可提升对接入该MBSR的UE的定位效果。Based on the above problems, an embodiment of the present application proposes a method for updating a cell identifier. When the network learns that a certain cell is a mobile cell, it can trigger a cell identifier update event to be subscribed to the MBSR corresponding to the cell, so as to timely obtain the latest cell identifier broadcast by the MBSR. The network element that executes the above subscription process may be an LMF network element or an AMF network element, which is not limited in the embodiment of the present application. In addition, in the F1 setup process, the MBSR may send the MBSR identifier to the host base station serving the MBSR, and the host base station may send the information of the MBSR cell (including the MBSR identifier, the cell identifier, and the mobility indication) to the network storage function NRF network element of the core network. When the information of the MBSR cell changes, the information stored in the NRF will be updated accordingly, thereby ensuring that the cell identifier of a certain MBSR obtained by the network is the latest. In summary, any of the above schemes can ensure that the network promptly obtains the latest cell identifier broadcast by the MBSR, thereby improving the positioning effect of the UE accessing the MBSR.
