网络连接的处理方法、终端及网络侧设备
相关申请的交叉引用
本申请要求于2023年09月07日提交中国专利局、申请号为202311157305.9、发明名称为“网络连接的处理方法、终端及网络侧设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请属于无线通信技术领域，具体涉及一种网络连接的处理方法、终端及网络侧设备。
背景技术
无线通信系统中的中继(Relay)技术，是指在基站与终端之间增加了一个或多个中继节点，负责对无线信号进行一次或者多次的转发，即无线信号要经过多跳才能到达终端。
无线中继技术不仅可用于扩展小区覆盖，弥补小区覆盖盲点，同时也可通过空间资源复用提升小区容量。对于室内覆盖，Relay技术也可起到克服穿透损耗，提升室内覆盖质量的作用。
以较简单的两跳中继为例，无线中继可以将一个基站—终端链路分割为基站—中继站和中继站—终端两个链路，从而有机会将一个质量较差的链路替换为两个质量较好的链路，以获得更高的链路容量及更好的覆盖。
目前LTE中已经支持的Relay为UE-to-Network中继，即中继一端连接UE，一端连接网络侧。与Relay连接的UE，叫做远端UE(Remote UE)。
在中继场景下，Remote UE可以与网络侧设备建立非直连路径(indirect path)或直连路径(direct path)。其中，非直连路径是指Remote UE通过Relay UE以及Relay UE的Uu空口与基站建立RRC连接的无线链路。直连路径是指Remote UE通过自己的Uu空口与基站建立RRC连接的无线链路。
然而相关技术中并没有给出Remote UE建立非直连路径的具体技术方案，从而可能导致在某些场景下，remote UE无法有效建立非直连路径。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚描述， 显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，本申请中的“或”表示所连接对象的至少其中之一。例如“A或B”涵盖三种方案，即，方案一：包括A且不包括B；方案二：包括B且不包括A；方案三：既包括A又包括B。字符“/”一般表示前后关联对象是一种“或”的关系。
本申请的术语“指示”既可以是一个直接的指示(或者说显式的指示)，也可以是一个间接的指示(或者说隐含的指示)。其中，直接的指示可以理解为，发送方在发送的指示中明确告知了接收方具体的信息、需要执行的操作或请求结果等内容；间接的指示可以理解为，接收方根据发送方发送的指示确定对应的信息，或者进行判断并根据判断结果确定需要执行的操作或请求结果等。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)或其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统以外的系统，如第6代(6th Generation，6G)通信系统。
图1a示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括中继终端11、网络侧设备12和远端终端13。在本申请实施例中，远端终端13可以通过中继终端11以及中继终端11的Uu空口与网络侧设备12建立RRC连接的无线链路，并且，远端终端13也可以通过远端终端13的Uu空口与网络侧设备12建立RRC连接的无线链路。
其中，中继终端11也可以称作中继(relay)终端设备或者中继用户终端(User Equipment，UE)，远端终端13也可以称作远端终端设备或者远端(remote)UE，中继终端11和远端终端13可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备，可穿戴式设备包括：手环、耳机、眼 镜等。需要说明的是，在本申请实施例并不限定中继终端11和远端终端13的具体类型。网络侧设备12可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
核心网设备可以包含但不限于如下至少一项：核心网节点、核心网功能、移动管理实体(Mobility Management Entity，MME)、接入移动管理功能(Access and Mobility Management Function，AMF)、会话管理功能(Session Management Function，SMF)、用户平面功能(User Plane Function，UPF)、策略控制功能(Policy Control Function，PCF)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)、边缘应用服务发现功能(Edge Application Server Discovery Function，EASDF)、统一数据管理(Unified Data Management，UDM)、统一数据仓储(Unified Data Repository，UDR)、归属用户服务器(Home Subscriber Server，HSS)、集中式网络配置(Centralized network configuration，CNC)、网络存储功能(Network Repository Function，NRF)、网络开放功能(Network Exposure Function，NEF)、本地NEF(Local NEF，或L-NEF)、绑定支持功能(Binding Support Function，BSF)、应用功能(Application Function，AF)等。需要说明的是，在本申请实施例中仅以NR系统中的核心网设备为例进行介绍，并不限定核心网设备的具体类型。
图1b示出相关技术中一种典型的UE-to-Network的场景，如图1b所示，在该场景下，Remote UE需要与网络侧传输数据，但由于覆盖不佳，找到Relay UE为其中转，其中Relay UE与基站之间是Uu接口，Relay UE和Remote UE之间是sidelink(PC5)接口。一般来说，Relay UE是开放的，可以为任何Remote UE服务。
另外，在相关技术中，还涉及多路径场景。例如，对于旁链路中继架构，如图2a至图2c所示，多路径是指Remote UE同时建立了indirect path和direct path。而对于非旁链路中继架构，即两个UE之间的连接并不是sidelink(PC5)接口，如图3a至图3c所示，两个UE之间的接口可以为有线连接或者理想的UE间连接(ideal inter-UE connection)，多路径是指Primary UE(与图2a至图2c中的remote UE角色相当)同时建立了indirect path和direct path。
由此可见，相关技术中的非直连路径(Indirect path)，指Remote UE(或Primary UE)通过Relay UE(或Secondary UE)以及Relay UE(或Secondary UE)的Uu空口与基站建立RRC连接的无线链路。直连路径(Direct path)，指Remote UE(或Primary UE)通过自己的Uu空口与基站建立RRC连接的无线链路。
而在车载移动场景下，如图4所示，智能手机(remote UE)通过wifi或蓝牙连接到 汽车的智能座舱(relay UE)，通过智能座舱(relay UE)的Uu空口与网络侧设备(gNB)建立非直连路径，从而实现智能手机的UL/DL数据传输。然而，智能手机本身也可以通过其Uu空口与网络侧设备建立直连路径，因此，关于智能手机在什么情况下通过非直连路径与网络侧设备通信，是相关技术中需要解决的技术问题，针对该问题，本申请实施实施例提供了一种网络连接的处理方法、终端及网络侧设备。
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网络连接的处理方法、终端及网络侧设备进行详细地说明。
需要说明的是，本申请实施例中的中继终端，可以是支持3GPP接入技术的中继终端，也可以是支持非3GPP接入技术的中继终端，还可以是支持3GPP接入技术和非3GPP接入技术的中继终端。后续各个实施例中仅以其中一种或多种类型的终端进行示例性说明，但支持不同接入技术的中继终端在各个实施例中可以相互替换。
图5示出本申请实施例中的网络连接的处理方法的一种流程示意图，该方法500可以由远端终端执行。换言之，所述方法可以由安装在远端终端上的软件或硬件来执行。如图5所示，该方法可以包括以下步骤。
S510，远端终端确定满足非直连路径建立条件。
在本申请实施例中，远端终端可以在处于非连接态时，确定有待传输的信息时，判断是否满足非直连路径建立条件，或者，远端终端也可以是在处于连接态时，判断是否满足非直连路径建立条件。
在本申请实施例的一个可选实现方式中，非直连路径建立条件可以包括以下至少之一：
(1)Remote UE当前的移动状态(mobility state)为预设状态，预设状态可以包括以下至少之一：高速移动状态(High-mobility state)、中速移动状态(Medium-mobility state)。其中，可以将Remote UE的移动状态(mobility state)可以分为三类：高速移动状态(High-mobility state)、中速移动状态(Medium-mobility state)、正常移动状态(Normal-mobility state)。因此，高速移动状态和中速移动状态，也可以定义为非正常移动状态(non Normal-mobility state)；中速移动状态和低速移动状态，也可以定义为非高速移动状态(non High-mobility state)。
可选地，远端终端可以基于在持续时间内发生小区重选的次数来确定远端终端当前的移动状态。例如，在所述远端终端在持续时间内发生小区重选的次数大于第一计数阈值的情况下，所述远端终端确定所述远端终端的移动状态为高速移动状态；在所述远端终端在持续时间内发生小区重选的次数小于或等于所述第一计数阈值、且大于或等于第二计数阈值的情况下，所述远端终端确定所述远端终端的移动状态为中速移动状态，其中，所述第一计数阈值大于所述第二计数阈值；在所述远端终端在所述持续时间内发生小区重选的次数小于所述第二计数阈值的情况下，所述远端终端确定所述远端终端的移动状态为正常移动状态。
可选地，上述持续时间、第一计数阈值和第二计数阈值可以是远端终端的服务基站发送的检测参数。例如，服务基站广播一组检测参数给Remote UE,这组参数包括：TCRmax,NCR_H,NCR_M。如果Remote UE判断在持续时间TCRmax内发生小区重选的次数大于NCR_H，则判断为满足高速移动状态的条件，进入高速移动状态(High-mobility state)。如果Remote UE判断在持续时间TCRmax内发生小区重选的次数小于或等于NCR_H，且大于或等于NCR_M，则判断为满足中速移动状态的条件，进入中速移动状态(Medium-mobility state)。如果Remote UE判断在持续时间TCRmax内发生小区重选的次数小于NCR_M，则判断为满足正常移动状态的条件，进入正常移动状态(Normal-mobility state)。
(2)Remote UE倾向于通过非直连路径建立或恢复或重建与网络侧设备的连接，例如，RRC连接。例如，Remote UE可以是至少基于自身移动速度、剩余电量、上行无线能力等因素确定其是否倾向于通过非直连路径建立或恢复或重建与网络侧设备的连接。
(3)Remote UE获取到所述网络侧设备发送的第一指示信息，且所述第一指示信息指示支持或允许所述远端终端通过中继终端与所述网络侧设备建立非直连路径。
在本申请实施例中，远端终端可以通过非3GPP无线接入技术(例如，wifi、红外通信或蓝牙通信等技术)与中继终端通信。在这种情况的中继终端简称为non-3GPP Relay UE。
在本申请实施例中，上述网络侧设备发送的第一指示信息可以是网络侧设备通过系统信息块(System Information Block，SIB)发送的。例如，Remote UE获取了其服务基站的SIB消息，所述SIB消息携带了是否支持或允许通过non-3GPP Relay UE与所述服务基站建立非直连路径的第一指示信息。在第一指示信息指示支持或允许通过non-3GPP Relay UE与所述服务基站建立非直连路径时，则判断满足非直连路径建立条件。在这种情况下，Remote UE将Relay UE的服务基站视作自己的服务基站。
(4)远端终端获取到所述中继终端的辅助信息，且所述辅助信息中包括以下至少一项：所述中继终端的Uu连接状态可用、所述中继终端担任中继角色的指示信息。
例如，Remote UE获取了non-3GPP Relay UE的辅助信息，所述辅助信息包括了Relay UE的Uu连接状态以及Relay UE是否担任中继角色(acting as relay UE)的指示信息。在所述辅助信息中的Relay UE的Uu连接状态可用且指示信息指示Relay UE担任中继角色的情况下，确定满足非直连路径建立条件。
其中，上述Relay UE的Uu连接状态可用可以是指Relay UE当前处于RRC连接态，或者，Relay UE当前处于RRC非连接态，但Relay UE的服务小区(PCell or Serving Cell)的RSRP质量高于预设阈值，即Relay UE的Uu信道条件较好。
在相关技术中，remote UE和relay UE具备旁链路(Sidelink)/PC5空口，可以基于Sidelink/PC5的发现(discovery)和中继选择或重选(relay(re)selection)功能触发非直连路径建立流程，但并不支持UE之间接口是wifi、蓝牙等非3GPP接口，而本申请实施例提供的上述方案可以针对non-3GPP中继的场景，实现基于non-3GPP relay的非直连路径的建立。
另外，对于remote UE和relay UE具备旁链路(Sidelink)/PC5空口的场景，可以将remote UE的服务小区的Uu参考信号接收功率(Reference Signal Received Power，RSRP)低于一定门限作为建立indirect path的触发条件，然而，在某些场景下，例如上述车载通信场景，如果只以远端终端的服务小区的Uu RSRP判断是否建立非直连路径可能并不能满足实际的需求，例如，远端终端如果处于高速移动状态，其服务小区的Uu RSRP可能较高，但由于远端终端处于高速移动状态，如果建立与网络侧设备的直连路径，则可能导致远端终端频繁地在小区间切换。又例如，远端终端可能基于自身移动速度、剩余电量、上行无线能力等因素确定倾向于与网络侧设备建立非直连路径，但远端终端的服务小区的Uu RSRP可能不低于预设门限，如果还基于服务小区的Uu RSRP判断是否建立非直连路径，显然不能满足远端终端的需求。因此，在本申请实施例中，在上述(1)至(4)的情况下，确定满足非直连路径建立条件。
S512，远端终端通过中继终端发起第一目标过程。
在本申请实施例中，所述第一目标过程包括以下任意一项：
RRC连接建立过程；
RRC连接恢复过程；
RRC连接重建过程。
