为了清楚地阐述本申请实施例的思想,首先对通信系统中。。。的处理过程进行简要描述。
服务化架构是5G网络架构中的重要特征,即核心网网元可以提供特定的服务,并通过定义的API接口供其他网元调用服务。图2示出了一种移动终端接入移动网络的系统架构图。其中,UE与基站进行接入层(Access Stratum,AS)连接,交互接入层消息及无线数据传输;UE与移动管理功能AMF进行非接入层(Non-access stratum,NAS)连接,交互NAS消息。AMF负责对UE移动性的管理,会话管理功能(Session Management Function,SMF)负责对UE的会话管理,AMF在 对移动终端进行移动性管理之外,还负责将从会话管理相关消息在UE和SMF之间的转发。策略控制功能(Policy Control Function,PCF)负责制定对UE的移动性管理、会话管理、计费等相关的策略。用户面功能UPF与基站及外部数据网络相连进行数据传输。
进一步,服务化架构中定义了两种服务,一是“Request-Response”(请求-响应),二是“Subscribe-Notify”(订阅-通知),其中前者是提供者接收到请求后立即发送回复消息且一般只回复一次,后者是提供者接收Subscribe后立即或延时Notify响应的内容,后续可能还会发送多次Notify。
另一方面,在服务化架构中可使用“Restful HTTP”(一种按照表述性状态转移(Representational State Transfer,Rest)风格设计的超文本传输协议HTTP接口)方式进行通信。例如,图2中的核心网控制面网元可以通过服务化接口(如图2中Nnssf接口、Npcf接口、Nudm接口等)将特定的服务功能提供给其他网元,提供服务的网元可称为“服务提供者”,使用服务的网元可称为“服务消费者”。例如当某网元需要使用某种服务时,其可以先与NRF交互,向NRF提供需要的服务的信息,由NRF返回服务提供者的信息,然后该网元可与服务提供者直接交互,得到相应的服务。
目前,服务化架构中仅NRF网元可执行以上描述的核心网网元的查找,对于除此之外的其他重要场景,例如设备至设备D2D(如UE与UE直通)等场景,目前的服务化架构还无法实现,有待进一步扩展和优化。
为此,本申请实施例提供一种用于建立通信连接的方法,应用于第一通信设备,参考图3,该方法包括:
S101,第一通信设备向网络功能实体发送注册信息,所述注册信息包括至少一个第一类标识,所述至少一个第一类标识与所述第一通信设备能够提供的至少一个服务相对应;
S102,所述第一通信设备接收所述网络功能实体发送的回复消息,所述回复消息包括注册结果。
根据本申请的实施例,第一通信设备可为终端侧设备(例如智能手机、手表等),也可为网络侧设备(例如基站等),第一通信设备可在给网络功能实体(例如核心网网元等)的注册信息中携带服务标识,从而将自身可提供的服务告知网络功能实体,如此,可通过网络功能实体实现服务的提供者和服务的消费者之间的相互发现和通信,服务的消费者能够便捷地得到相应服务,网络的服务化架构得到了扩展和优化。
根据本申请的实施例,可选地,所述第一类标识包括以下至少一项:分析标识Analytics ID、人工智能模型标识AI model ID、应用ID。

以上通过多个实施例描述了本申请实施例的用于建立通信连接的方法的实现方式,以下通过具体的例子描述本申请实施例的具体实现过程。在以下实施例中,以服务的提供者和消费者均为终端设备、通过核心网网元NRF进行注册和查找为例进行描述。
过程1:注册请求过程
在本实施例中,服务的提供者和消费者均为终端设备,分别记为UE-1和UE-2,其中UE-1通过核心网网元NRF进行注册,注册请求过程可参考图6,UE-1可以通过NAS消息发送注册请求,具体描述如下。
1、UE-1可以是服务的提供者(Service provider),UE-1向NRF发送注册请求消息,请求消息中包含服务标识(或者说服务ID),具体地:
●服务标识表示UE-1设备自身支持(或者说:允许、激活、请求)的业务或应用的标识;以下示例性地列举:
·分析标识(Analytics ID):可指示该UE-1能够执行或提供的数据处理方式,和/或人工智能业务;
·人工智能模型标识(AI model ID):可用于指示UE-1支持或使用的AI模型;
·应用ID:指示UE-1支持的应用。
进一步,注册请求消息还可以包括如下参数中的至少之一:
●UE类型(如:UE为智能手机、物联网设备、车联网设备);
●UE能力(如:计算能力、存储能力、通信能力);
●UE地址(如:互联网协议IP地址、MAC地址);
●UE标识(如:通用公共用户标识符(Generic Public Subscription Identifier,GPSI)、用户永久标识符(SUbscription Permanent Identifier,SUPI)、全球唯一临时标识符(Globally Unique Temporary UEIdentity,GUTI));
●UE的PLMN ID和/或小区ID等。
2、NRF接收UE-1的注册请求,可存储该UE的信息。
其中,可选地,UE-1发送的请求消息也可以通过其他核心网网元接收,然后发送给NRF。比如,AMF接收UE的请求消息,并发送给NRF。
3、NRF反馈结果:注册成功,可选地,还返回该请求对应的临时标识或称临时编码。
其中,NRF返回给UE-1的临时标识/编码可以是NRF生成、管理的,该临时标识/编码可以用于标识该UE-1对应的服务,服务标识的不同取值对应不同的临时标识或临时编码,且服务标识的不同取值对应UE的不同服务。参考表1,其中示意性列举了3个Analytics ID、2个AI model ID、2个应用ID以及它们分别对应的不同的临时编码。
表1
服务标识 临时标识/编码
分析标识Analytics ID=a 0000
分析标识Analytics ID=b 0001
分析标识Analytics ID=c 0010
人工智能模型标识AI model ID=d 0100
人工智能模型标识AI model ID=e 0011
应用ID=f 0110
应用ID=g 1100
使用临时标识/编码代替服务标识,可避免在空口上直接交互服务信息或服务标识等敏感信息。可选地,后续需要时(例如向UE-2反馈服务的提供者信息时)NRF还可以更新该临时标识/编码。
过程2:查找请求过程
在本实施例中,UE-2通过核心网网元NRF发现UE-1,参考图7,具体描述如下。
1、UE-2发送查找请求消息,查找请求消息中包含服务标识(或者说服务ID),具体地:
●服务标识表示UE-2设备自身请求(或者说:支持、允许、激活)的业务或应用的标识;以下示例性地列举:
·Analytics ID:可指示该UE-2能够执行或提供的数据处理方式和/或人工智能业务;
·AI model ID:可用于指示UE-2支持或使用的AI模型;
·应用ID:指示UE-2支持的应用。
进一步,查找请求消息还可以包括如下参数中的至少之一:
●UE类型(如:UE为智能手机、物联网设备、车联网设备);
●UE能力(如:计算能力、存储能力、通信能力);
●UE地址(如:IP地址、MAC地址);
●UE标识(如:GPSI、SUPI、GUTI);
●UE的PLMN ID和/或小区ID等。
●查找请求通信的UE数量(该数量可以为一个或多个,NRF可据此返回相应数量的
UE的信息)。
2、NRF接收到查找请求消息后,根据UE-2在请求消息中携带的参数(如服务ID)来查找符合条件的UE(一个或多个);
3、NRF在回复消息中反馈查询结果(如查询成功)以及对应的UE信息(如UE-1的标识、地址等),该UE信息用于UE-2发现或者说找到UE-1。
其中,可选地,回复消息中还可包含对应的临时标识/编码,该临时标识/编码可以与注册过程中NRF反馈给UE-1的临时标识/编码相同。可选地,后续需要时NRF可以再次更新该临时标识/编码给UE-2。
过程3:UE-2与UE-1建立连接
在本实施例中,UE-2与UE-1之间建立连接,可采用如下多种方式中至少一种,以下分别具体描述。
方式1:通过PC5接口建立连接
参考图8,UE-2根据从网络侧得到的信息,通过PC5接口与UE1之间建立连接。
0、可选地,UE-1在执行图5实施例的注册过程之后,UE-1可以根据收到的临时标识/编码进行系统广播,将接收到的临时标识/编码广播出来;
1、UE-2在执行图6实施例的查询请求后,可根据收到的UE参数确可为其提供服务的UE,例如为UE-1,则UE-2向UE-1发起连接请求。可选地,连接请求可以以单播或广播形式发送。
2、可选地,UE-2与UE-1建立连接的过程中可以包含安全过程,还可以通过UE1和UE2各自的层2标识来唯一标识该PC5连接。建立好连接后,可以执行一对一直接通信(one to one direct communication),还可用于特定业务的通信。另外,如果UE-2在查询过程(图6实施例)中获得了多个UE的信息,则UE-2可以向多个UE发送连接请求,执行一对多直接通信(one to multiple direct communication)。
方式2:UE2与UE-1通过各自网络的用户面建立连接
参考图9,在该场景下,UE-2可以发起应用层连接(如HTTP建立请求),从而通过Uu接口用户面与UE-1建立连接。比如,UE-2根据查询请求过程中获得的UE-2的地址信息向UE-1发起HTTP 连接建立请求,完成与UE-1的通信连接,获取需要的服务。
利用本申请的以上至少一个实施例,通信设备之间可借助网络来发现需要的服务的提供者,该过程可基于目前的NRF的服务化架构实现,并优化服务化架构的功能,利用本申请实施例的方案可以以新的接口定义实现最小的技术开销,从整体上提升系统性能。
