为了方便理解本公开实施例,下面介绍与本公开实施例相关的术语或背景:To facilitate understanding of the embodiments of the present disclosure, the following introduces terms or backgrounds related to the embodiments of the present disclosure:
(1)层3(Layer-3)终端到网络(UE-to-Network)中继(Relay)架构和流程(1) Layer 3 UE-to-Network Relay Architecture and Process
相关技术定义了Layer-3 UE-to-Network Relay架构和相关流程。图1是本公开提供的网络架构示意图,如图1所示,当UE处于网络覆盖范围之外或者Uu接口信号较差时,无法直接连接网络,可通过具有中继功能的UE连接网络,前者称为层3远端终端(Layer-3 Remote UE,也可以称为远端终端),后者称为层3中继终端(Layer-3 Relay UE,也可以称为中继终端)。Layer-3UE-to-Network Relay场景下,远端终端通过直连通信(PC5)接口与中继终端连接,中继终端通过UU接口与接入网连接,接入网可以为下一代无线接入网(Next Generation Radio Access Network,NG-RAN),接入与核心网连接,核心网可以为5G核心网(5G Core,5GC),核心网通过N6接口与数据网连接。The related technology defines the Layer-3 UE-to-Network Relay architecture and related processes. FIG1 is a schematic diagram of the network architecture provided by the present disclosure. As shown in FIG1, when the UE is out of the network coverage or the Uu interface signal is poor, it cannot directly connect to the network. It can connect to the network through a UE with a relay function. The former is called a layer 3 remote terminal (Layer-3 Remote UE, also called a remote terminal), and the latter is called a layer 3 relay terminal (Layer-3 Relay UE, also called a relay terminal). In the Layer-3 UE-to-Network Relay scenario, the remote terminal is connected to the relay terminal through the direct communication (PC5) interface, and the relay terminal is connected to the access network through the UU interface. The access network can be the next generation radio access network (Next Generation Radio Access Network, NG-RAN), and the access is connected to the core network. The core network can be a 5G core network (5G Core, 5GC), and the core network is connected to the data network through the N6 interface.
图2是本公开提供的远端终端通过中继终端与网络进行通信的流程示意图,如图2所示:FIG. 2 is a schematic diagram of a process of a remote terminal communicating with a network through a relay terminal provided by the present disclosure, as shown in FIG. 2 :
1、网络通过接入和移动性管理功能(Access and Mobility Management Function,AMF)和用户面功能(User Plane Function,UPF)等为远端终端(Remote UE)和中继终端(Relay UE)注册,并向远端终端和中继终端这次提供进行ProSe(Proximity Service,邻近业务)通信(通过PC5接口通信)所需的参数,如用于选择中继终端的中继服务代码(Relay Service Code)。
1. The network registers the remote UE and the relay UE through the Access and Mobility Management Function (AMF) and the User Plane Function (UPF), and provides the remote UE and the relay UE with the parameters required for ProSe (Proximity Service) communication (communicating through the PC5 interface), such as the relay service code (Relay Service Code) used to select the relay terminal.
2、中继终端通过会话管理功能(Session Management Function,SMF)建立Uu接口的中继协议数据单元(Protocol Data Unit,PDU会话),所述中继协议PDU会话用于中继远端终端的数据传输。中继终端通过互联网协议第6版(Internet Protocol Version 6,IPv6)前缀代理功能从网络获取IPv6前缀(IPv6prefix)。2. The relay terminal establishes a relay protocol data unit (PDU session) of the Uu interface through the session management function (SMF), and the relay protocol PDU session is used to relay the data transmission of the remote terminal. The relay terminal obtains the IPv6 prefix (IPv6prefix) from the network through the Internet Protocol Version 6 (IPv6) prefix proxy function.
3、远端终端执行ProSe发现过程发现中继终端。3. The remote terminal performs the ProSe discovery process to discover the relay terminal.
4、远端终端选择中继终端并建立一对一直接通信,远端终端和中继终端之间的通信接口为PC5接口。如果远端终端需要新建PDU会话,中继终端发起新的PDU会话建立过程。4. The remote terminal selects the relay terminal and establishes one-to-one direct communication. The communication interface between the remote terminal and the relay terminal is the PC5 interface. If the remote terminal needs to create a new PDU session, the relay terminal initiates a new PDU session establishment process.
5、中继终端为远端终端分配IP地址。5. The relay terminal assigns an IP address to the remote terminal.
(2)5G***支持终端进行紧急业务的方法(2) How 5G systems support terminals in performing emergency services
相关技术定义了终端直接接入网络(也即终端不通过Relay终端接入网络)时,终端进行紧急业务的方法。The related art defines a method for a terminal to perform emergency services when the terminal directly accesses the network (that is, the terminal does not access the network through a relay terminal).
在注册(Registration)过程中,AMF在注册接受Registration Accept消息中向终端指示紧急业务支持标识Emergency Service Support indicator,用于通知终端网络支持紧急业务,也即UE可以向网络请求进行紧急业务emergency service的PDU会话。在PDU会话建立过程中,UE将请求类型Request Type设为紧急业务请求Emergency Request,用于指示UE请求建立支持紧急业务的PDU会话。AMF根据该指示和紧急业务配置数据Emergency Configuration Data来选择支持紧急业务的SMF以完成PDU会话建立过程,其中紧急业务配置数据Emergency Configuration Data包含紧急业务Emergency单网络切片选择辅助信息(Single Network Slice Selection AssistanceInformation,S-NSSAI)和紧急业务Emergency数据网络名称(Data Network Name,DNN)。During the registration process, the AMF indicates the Emergency Service Support indicator to the terminal in the Registration Accept message, which is used to notify the terminal that the network supports emergency services, that is, the UE can request the network to conduct a PDU session for the emergency service. During the PDU session establishment process, the UE sets the request type Request Type to Emergency Request, which is used to indicate that the UE requests to establish a PDU session that supports emergency services. The AMF selects the SMF that supports emergency services based on the indication and the Emergency Configuration Data to complete the PDU session establishment process, where the Emergency Configuration Data includes the Emergency single network slice selection assistance information (Single Network Slice Selection Assistance Information, S-NSSAI) and the Emergency data network name (Data Network Name, DNN).
此外,相关技术还定义了终端支持紧急业务的4种不同情形,包括:In addition, the relevant technology also defines four different situations in which the terminal supports emergency services, including:
(1)仅支持有效的终端(Valid UE only),即只有当UE具有合法签约、并且被认证和授权可以进行数据业务时,才可以请求紧急业务。不支持处于限制服务limited service状态的UE请求紧急业务。
(1) Only valid UEs are supported, that is, only UEs with a valid contract, authenticated and authorized to perform data services can request emergency services. UEs in the limited service state are not supported to request emergency services.
(2)仅允许被认证的UE Only UEs that are authenticated are allowed,即UE必须具有合法IMSI、且经过认证才可以请求紧急业务。支持限制服务(limited service)状态的UE请求紧急业务。(2) Only UEs that are authenticated are allowed, that is, the UE must have a valid IMSI and be authenticated to request emergency services. UEs in limited service status are supported to request emergency services.
(3)需要国际移动用户识别码(International Mobile Subscriber Identity,IMSI)身份验证可选(authentication optional),即UE必须具有合法IMSI,即使认证失败,UE仍可请求紧急业务,此时使用IMSI作为UE标识。(3) International Mobile Subscriber Identity (IMSI) authentication is optional, that is, the UE must have a valid IMSI. Even if the authentication fails, the UE can still request emergency services, in which case IMSI is used as the UE identifier.
(4)所有的UE都被允许(All UEs are allowed),包括被认证的UE、具有IMSI但无法认证的UE、以及只有IMSI的UE,都可以请求紧急业务。(4) All UEs are allowed, including authenticated UEs, UEs with IMSI but unable to be authenticated, and UEs with only IMSI, can request emergency services.
相关技术定义了UE直接接入网络(也即UE不通过中继终端接入网络)时,UE可从网络获知当前接入网络是否支持紧急业务,以及网络支持何种情形的UE可以请求紧急业务。The relevant technology defines that when a UE directly accesses a network (ie, the UE does not access the network through a relay terminal), the UE can learn from the network whether the currently accessed network supports emergency services, and under what circumstances the network supports the UE to request emergency services.
但在中继场景中,如在Layer-3 UE-to-Network Relay架构中,由于远端终端无法建立自己的PDU会话,而是借助中继终端的PDU会话与网络进行通信。远端终端如何选择合适的中继终端以支持紧急业务是本公开要解决的问题。However, in relay scenarios, such as in the Layer-3 UE-to-Network Relay architecture, the remote terminal cannot establish its own PDU session, but communicates with the network with the help of the PDU session of the relay terminal. How the remote terminal selects a suitable relay terminal to support emergency services is a problem to be solved by the present disclosure.
下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本公开一部分实施例,并不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.
图3是本公开实施例提供的紧急业务的处理方法的流程示意图之一,如图3所示,本公开实施例提供一种紧急业务的处理方法,应用于远端终端,包括:FIG3 is a flowchart of a method for processing emergency services provided by an embodiment of the present disclosure. As shown in FIG3 , an embodiment of the present disclosure provides a method for processing emergency services, which is applied to a remote terminal and includes:
步骤310,获取候选中继终端对应的第二紧急业务信息;Step 310, obtaining second emergency service information corresponding to the candidate relay terminal;
具体地,候选中继终端是指能够被远端终端发现的中继终端,第二紧急业务信息是指候选中继终端对应的紧急业务信息,如候选中继终端支持的、紧急业务的相关的信息;示例性地,第二紧急业务信息可以包括:是否支持
紧急业务,所需要的紧急业务类型,建立紧急业务所需要的参数(如需要接入的网络等)。Specifically, the candidate relay terminal refers to a relay terminal that can be discovered by the remote terminal, and the second emergency service information refers to the emergency service information corresponding to the candidate relay terminal, such as the information related to the emergency service supported by the candidate relay terminal; illustratively, the second emergency service information may include: whether to support Emergency services, the type of emergency services required, and the parameters required to establish emergency services (such as the network that needs to be accessed, etc.).
第二紧急业务信息可以是网络配置的、网络通知的、远端终端向候选中继终端请求的或者候选中继终端向远端终端发送的。示例性地,中远端终端可以与网络建立过连接或与候选中继终端建立过连接,接收并保存候选中继终端相关的第二紧急业务信息。The second emergency service information may be configured by the network, notified by the network, requested by the remote terminal to the candidate relay terminal, or sent by the candidate relay terminal to the remote terminal. For example, the remote terminal may have established a connection with the network or with the candidate relay terminal, and receive and save the second emergency service information related to the candidate relay terminal.
应理解,以上是为便于理解本公开进行的举例,本公开实施例对第二紧急业务信息的获取方法不做限定。It should be understood that the above is an example for facilitating understanding of the present disclosure, and the embodiment of the present disclosure does not limit the method for acquiring the second emergency service information.

第一紧急业务信息是与远端终端需要执行的紧急业务相关的信息,如,是否支持紧急业务,所需要的紧急业务类型,建立紧急业务所需要的参数(如上文介绍的紧急业务配置数据等)。The first emergency service information is information related to the emergency service that the remote terminal needs to execute, such as whether the emergency service is supported, the required emergency service type, and the parameters required to establish the emergency service (such as the emergency service configuration data introduced above).

候选中继终端的数量可以为多个,因此与候选中继终端对应的第二紧急业务信息也可以有多个。候选中继终端可能能够与远端终端建立连接,但是由于候选中继终端的中继能力以及候选中继终端可能分别与不同的网络连接等因素的影响,不同候选中继终端紧急业务中继能力(即不同的候选中继终端是否支持为远端终端提供紧急业务中继)是不同的,并且由于候选中继终端所连接的网络的不同,候选中继终端是否能够为远端终端提供紧急业务的情况也随之不同。There may be multiple candidate relay terminals, so there may be multiple second emergency service information corresponding to the candidate relay terminals. The candidate relay terminal may be able to establish a connection with the remote terminal, but due to the relay capability of the candidate relay terminal and the fact that the candidate relay terminal may be connected to different networks, the emergency service relay capabilities of different candidate relay terminals (i.e., whether different candidate relay terminals support providing emergency service relay for remote terminals) are different, and due to the different networks to which the candidate relay terminals are connected, whether the candidate relay terminals can provide emergency services for remote terminals is also different.
远端终端可以根据第一紧急业务信息和所述第二紧急业务信息选择能够为远端终端提供紧急业务中继业务的候选中继终端作为目标中继终端。
The remote terminal may select a candidate relay terminal that can provide the remote terminal with an emergency service relay service as a target relay terminal according to the first emergency service information and the second emergency service information.
步骤330,向所述目标中继终端发送用于建立所述紧急业务的第一消息。Step 330: Send a first message for establishing the emergency service to the target relay terminal.
具体地,向目标中继终端发送第一消息,请求目标中继终端为远端终端建立所述紧急业务。所述紧急业务是指所述远端终端需要执行的紧急业务。Specifically, a first message is sent to the target relay terminal to request the target relay terminal to establish the emergency service for the remote terminal. The emergency service refers to the emergency service that the remote terminal needs to execute.
本公开实施例提供的紧急业务的处理方法,可以应用于中继场景,如Layer-3 UE-to-Network Relay,通过第一紧急业务信息和所述第二紧急业务信息确定目标中继终端,并向目标中继终端请求建立所述远端终端需要执行的紧急业务,实现了远端终端借助目标中继终端的PDU会话与网络进行通信,由目标中继终端为远端终端提供数据传输,从而使得远端终端能够获得紧急业务支持,解决了远端终端由于无法直接接入网络导致的无法执行所需的紧急业务的问题。The method for processing emergency services provided by the embodiments of the present disclosure can be applied to relay scenarios, such as Layer-3 UE-to-Network Relay, and determines the target relay terminal through the first emergency service information and the second emergency service information, and requests the target relay terminal to establish the emergency service that the remote terminal needs to execute, thereby enabling the remote terminal to communicate with the network with the help of the PDU session of the target relay terminal, and the target relay terminal provides data transmission for the remote terminal, so that the remote terminal can obtain emergency service support, thereby solving the problem that the remote terminal cannot execute the required emergency service due to the inability to directly access the network.

Network slicing is an on-demand networking method that allows operators to separate multiple virtual end-to-end networks on a unified infrastructure. DNN can be applied to select SMF and UPF for PDU sessions, select N6 interface for PDU sessions, and determine the policy to be applied to this PDU session.

对于第二紧急业务支持标识,是指候选中继终端对应的紧急业务支持标识,用于指示所对应的候选中继终端是否支持紧急业务。应理解,由于候选中继终端的数量可以有多个,每个候选中继终端分别对应一个第二紧急业务支持标识,因此第二紧急业务支持标识也可以有多个。The second emergency service support identifier refers to the emergency service support identifier corresponding to the candidate relay terminal, which is used to indicate whether the corresponding candidate relay terminal supports emergency services. It should be understood that since there can be multiple candidate relay terminals, each candidate relay terminal corresponds to a second emergency service support identifier, so there can also be multiple second emergency service support identifiers.

应理解,由于候选中继终端的数量可以有多个,每个候选中继终端分别对应第二PDU会话参数,因此第二PDU会话参数也可以有多个。It should be understood that, since there may be multiple candidate relay terminals, each candidate relay terminal corresponds to a second PDU session parameter, and therefore there may also be multiple second PDU session parameters.
可选地,所述第二PDU会话参数包括第二紧急业务DNN和/或第二紧急业务S-NSSAI。Optionally, the second PDU session parameters include a second emergency service DNN and/or a second emergency service S-NSSAI.

具体地,对于在远端终端具有合法签约、被网络认证和授权且可进行数据业务情况下,为所述远端终端提供紧急业务可以包括有效远端终端和注册的远端终端两种情形。Specifically, in the case where the remote terminal has a legal contract, is authenticated and authorized by the network, and can perform data services, providing emergency services for the remote terminal may include two situations: a valid remote terminal and a registered remote terminal.
有效远端终端情形是指:网络只允许候选中继终端为有效远端终端中继紧急业务,即只有有效远端终端才可以请求紧急业务,并且不支持处于限制服务状态的远端终端请求紧急业务。有效远端终端是指:远端终端具有合法签约、并且被认证和授权可以进行数据业务。
The valid remote terminal scenario means that the network only allows candidate relay terminals to relay emergency services for valid remote terminals, that is, only valid remote terminals can request emergency services, and does not support remote terminals in restricted service status to request emergency services. A valid remote terminal means that the remote terminal has a legal contract and is authenticated and authorized to perform data services.
注册的远端终端情形是指:网络只允许候选中继终端为注册的远端终端中继紧急业务,即远端终端必须具有合法IMSI、且经过认证才可以请求紧急业务。支持限制服务状态的远端终端请求紧急业务。The registered remote terminal scenario means that the network only allows candidate relay terminals to relay emergency services for registered remote terminals, that is, the remote terminal must have a valid IMSI and be authenticated before it can request emergency services. Supports remote terminals in restricted service status to request emergency services.
对于为具有国际移动用户识别码IMSI的远端终端提供紧急业务,是指网络只允许候选中继终端为有IMSI的远端终端中继紧急业务,即远端终端必须具有合法IMSI才能请求紧急业务。远端终端必须具有合法IMSI,即使认证失败,远端终端仍可请求紧急业务,此时使用IMSI作为远端终端标识。Providing emergency services to remote terminals with International Mobile Subscriber Identity (IMSI) means that the network only allows candidate relay terminals to relay emergency services for remote terminals with IMSI, that is, remote terminals must have a valid IMSI to request emergency services. The remote terminal must have a valid IMSI. Even if the authentication fails, the remote terminal can still request emergency services. At this time, IMSI is used as the remote terminal identifier.

在A类型发现过程中,Relay UE发送广播消息,该消息中包含第二紧急业务信息(第二Emergency RSC、第二Emergency DNN,第二Emergency S-NSSAI、Emergency type)其中第二Emergency RSC、第二Emergency DNN,第二Emergency S-NSSAI、Emergency type是Relay UE在注册过程中从AMF获得的(图5介绍的实施例)。
In the A type discovery process, the Relay UE sends a broadcast message, which includes the second emergency service information (second Emergency RSC, second Emergency DNN, second Emergency S-NSSAI, Emergency type), where the second Emergency RSC, second Emergency DNN, second Emergency S-NSSAI, and Emergency type are obtained by the Relay UE from the AMF during the registration process (the embodiment introduced in Figure 5).
在B类型发现过程中,Remote UE向Relay UE发送请求Solicitation消息,请求消息中包含第一Emergency RSC,Relay UE向Remote UE返回响应Response消息,响应消息中包含第二紧急业务信息(第二Emergency RSC、第二Emergency DNN,第二Emergency S-NSSAI、Emergency type)。其中第二Emergency RSC、第二Emergency DNN,第二Emergency S-NSSAI、Emergency type是Relay UE在注册过程中从AMF获得的(可以参考图5介绍的实施例)。In the B type discovery process, the Remote UE sends a Solicitation message to the Relay UE, which includes the first Emergency RSC. The Relay UE returns a Response message to the Remote UE, which includes the second emergency service information (second Emergency RSC, second Emergency DNN, second Emergency S-NSSAI, Emergency type). The second Emergency RSC, second Emergency DNN, second Emergency S-NSSAI, and Emergency type are obtained by the Relay UE from the AMF during the registration process (refer to the embodiment described in Figure 5).
进一步的,Relay UE可根据Emergency type确定Remote UE是否需要进行认证过程。如果为具有国际移动用户识别码IMSI的远端终端提供紧急业务(IMSI required,authentication optional)或为所有远端终端提供紧急业务(All UEs are allowed),那么说明Remote UE不需要执行认证过程,Relay UE可在发现过程中的响应消息中增加不需要执行认证authentication not required指示,Remote UE在收到该指示后将不再发起认证过程。Furthermore, the Relay UE can determine whether the Remote UE needs to perform the authentication process according to the Emergency type. If emergency services are provided for remote terminals with an International Mobile Subscriber Identity IMSI (IMSI required, authentication optional) or for all remote terminals (All UEs are allowed), it means that the Remote UE does not need to perform the authentication process. The Relay UE can add an authentication not required indication in the response message during the discovery process. After receiving the indication, the Remote UE will no longer initiate the authentication process.
应理解,此时的中继终端为候选中继终端。It should be understood that the relay terminal at this time is a candidate relay terminal.
3、Remote UE选择合适的候选中继终端作为目标中继终端,需要考虑以下因素:3. The Remote UE selects a suitable candidate relay terminal as the target relay terminal, and needs to consider the following factors:
(1)Remote UE从PCF获取的第一紧急业务RSC和关联的第一PDU会话参数(第一紧急业务DNN和/或第一紧急业务S-NSSAI)能够与发现消息中获得的第二Emergency DNN和第二Emergency S-NSSAI匹配。(1) The first emergency service RSC and the associated first PDU session parameters (first emergency service DNN and/or first emergency service S-NSSAI) obtained by the Remote UE from the PCF can match the second Emergency DNN and the second Emergency S-NSSAI obtained in the discovery message.
(2)Remote UE当前的状态(例如是否有IMSI,是否处于限制服务limited state等)能够满足Emergency type中的一种情形。(2) The current status of the Remote UE (e.g. whether it has an IMSI, whether it is in a restricted service state, etc.) can satisfy one of the scenarios in the Emergency type.
4、Remote UE与目标中继终端建立PC5连接。Remote UE在直接通信请求Direct Communication Request消息(第一消息)中包含第一Emergency RSC。4. The Remote UE establishes a PC5 connection with the target relay terminal. The Remote UE includes the first Emergency RSC in the Direct Communication Request message (first message).
5、目标中继终端建立紧急业务PDU会话。5. The target relay terminal establishes an emergency service PDU session.
另外的,Remote UE也可以通过目标中继终端Relay UE建立非紧急业务PDU会话,此时Remote UE和目标中继终端建立单独的PC5连接。当目标中
继终端处于移动能力限制Mobility restriction时,将发起释放非紧急业务会话,但是保留紧急业务会话。In addition, the Remote UE can also establish a non-emergency service PDU session through the target relay terminal Relay UE. At this time, the Remote UE and the target relay terminal establish a separate PC5 connection. When the terminal is in the state of mobility restriction, it will initiate the release of non-emergency service sessions, but retain emergency service sessions.
6、Remote UE的数据通过目标中继终端进行转发。6. The Remote UE’s data is forwarded through the target relay terminal.
