具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。
本申请实施例中涉及的网元包括接入网设备和终端设备。
接入网设备是网络侧中一种用于发射或接收信号的实体，如新一代基站(generation Node B，gNodeB或gNB)。接入网设备可以是用于与移动设备通信的设备。接入网设备可以是无线局域网(wireless local area networks，WLAN)中的接入点(access point，AP)，可以是长期演进(long term evolution，LTE)中的演进型基站(evolutional Node B，eNB或eNodeB)，或者中继站或接入点或接入回传一体化(integrated access and backhaul，IAB)，或者车载设备、可穿戴设备以及5G网络中的接入网设备或者未来演进的公共陆地移动网络(public land mobile network，PLMN)网络中的接入网设备，或新无线(new radio，NR)系统中的gNB等。另外，在本申请实施例中，接入网设备为小区提供服务，终端设备通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与接入网设备进行通信。本申请实施例中的接入网设备可以是指集中单元(central unit，CU)或者分布单元(distributed unit，DU)。或者，接入网设备也可以是CU和DU组成的，例如，如图1所示。其中，CU和DU在物理上可以是分离的，也可以部署在一起，本申请实施例对此不 做具体限定。一个CU可以连接一个DU，或者也可以多个DU共用一个CU，可以节省成本，以及易于网络扩展。CU和DU的切分可以按照协议栈切分，其中一种可能的方式是将无线资源控制(radio resource control，RRC)、业务数据适配协议栈(service data adaptation protocol，SDAP)以及分组数据汇聚协议(packet data convergence protocol，PDCP)层部署在CU，其余的无线链路控制(radio link control，RLC)层、介质访问控制(media access control，MAC)层以及物理层部署在DU。本申请实施例中并不完全限定上述协议栈切分方式，还可以有其它的切分方式。CU和DU之间通过F1接口连接。CU代表gNB通过Ng接口和核心网连接。本申请实施例中的接入网设备可以是指集中式单元控制面(CU-CP)节点或者集中式单元用户面(CU-UP)节点，或者，网络设备也可以是CU-CP和CU-UP。其中CU-CP负责控制面功能，主要包含RRC和PDCP-C。PDCP-C主要负责控制面数据的加解密，完整性保护，数据传输等。CU-UP负责用户面功能，主要包含SDAP和PDCP-U。其中SDAP主要负责将核心网的数据进行处理并将流(flow)映射到承载。PDCP-U主要负责数据面的加解密，完整性保护，头压缩，序列号维护，数据传输等。其中CU-CP和CU-UP通过E1接口连接。CU-CP代表gNB通过Ng接口和核心网连接。通过F1-C(控制面)和DU连接。CU-UP通过F1-U(用户面)和DU连接。当然还有一种可能的实现是PDCP-C也在CU-UP。如图2所示，本申请实施例所提及的接入网设备可以为包括CU、或DU、或包括CU和DU的设备、或者控制面CU节点(CU-CP节点)和用户面CU节点(CU-UP节点)以及DU节点的设备。此外，在其它可能的情况下，接入网设备可以是其它为终端设备提供无线通信功能的装置。本申请的实施例对接入网设备所采用的具体技术和具体设备形态不做限定。为方便描述，本申请实施例中，为终端设备提供无线通信功能的装置称为接入网设备。
终端设备可以是能够接收接入网设备调度和指示信息的终端设备，终端设备可以是指向用户提供语音和/或数据连通性的设备，或具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。终端设备可以经无线接入网(如，radio access network，RAN)与一个或多个核心网或者互联网进行通信，终端设备可以是移动终端设备，如移动电话(或称为“蜂窝”电话，手机(mobile phone))、计算机和数据卡，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(personal communications service，PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、平板电脑(Pad)、带无线收发功能的电脑等设备。终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile station，MS)、远程站(remote station)、接入点(access point，AP)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户站(subscriber station，SS)、用户端设备(customer premises equipment，CPE)、终端(terminal)、用户设备(user equipment，UE)、移动终端(mobile terminal，MT)等。终端设备也可以是可穿戴设备以及下一代通信系统，例如，5G网络中的终端设备或者未来演进的PLMN网络中的终端设备，NR通信系统中的终端设备等。
此外，本申请实施例还可以适用于面向未来的其他通信技术。本申请描述的网络架构以及业务场景是为了更加清楚的说明本申请的技术方案，并不构成对本申请提供的技术方 案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请提供的技术方案对于类似的技术问题，同样适用。
可以理解的，本申请实施例中，终端设备和/或网络设备可以执行本申请实施例中的部分或全部步骤，这些步骤或操作仅是示例，本申请实施例还可以执行其它操作或者各种操作的变形。此外，各个步骤可以按照本申请实施例呈现的不同的顺序来执行，并且有可能并非要执行本申请实施例中的全部操作。
需要说明的是，本申请实施例不限定以上通信系统的类型和制式。例如：所述通信系统可以为：5G通信系统、LTE通信系统、6G通信系统、非地面网络(non-terrestrial network，NTN)系统等。
在NR中，终端设备的RRC状态包括connected态，inactive态，idle态，其中，终端设备处于inactive态时，终端设备和接入网设备之间挂起RRC连接，但终端设备与接入网设备会保存终端设备的上下文信息。
接入网设备配置终端设备进入inactive态时，会向终端设备发送I-RNTI。I-RNTI用于接入网设备获取终端设备的上下文信息，例如I-RNTI和终端设备在锚点接入网设备上的上下文信息是对应的，通过I-RNTI可以找到该终端设备的上下文信息。举例而言，I-RNTI目前有2种长度，一种为40比特(bit)，一般称为长I-RNTI(full I-RNTI)，一种为24bit，一般称为短I-RNTI(short I-RNTI)。I-RNTI中的信息可以包括终端设备的标识和接入网设备的标识(比如锚点接入网设备标识)。本申请实施例以I-RNTI有2种长度为例进行描述，对I-RNTI的长度并不限制。
当有业务需求时(比如，终端设备有上行数据需要发送，或者收到寻呼消息)，inactive态的终端设备发起RRC恢复过程。如图3所示，RRC恢复过程可以如下：
S301，终端设备向目标接入网设备发送RRC恢复请求(RRC resume request)消息。
其中，RRC resume request消息携带终端设备的I-RNTI。
目标接入网设备为终端设备发起RRC恢复的接入网设备。
S302，目标接入网设备向锚点接入网设备发送获取终端设备上下文信息请求(Retrieve UE context request)消息。
其中，Retrieve UE context request消息携带终端设备的I-RNTI。
锚点接入网设备为配置终端设备进入inactive态的接入网设备，也可以称为源接入网设备。
具体的，目标接入网设备可以根据该I-RNTI中锚点接入网设备的标识信息，确定锚点接入网设备，进而向锚点接入网设备发送Retrieve UE context request消息。比如，目标接入网设备可以根据该I-RNTI中锚点接入网设备的标识信息，确定对应的全局接入网设备标识信息，进而确定对应的锚点接入网设备。
S303，锚点接入网设备向目标接入网设备发送响应消息。
响应消息可以是获取终端设备上下文信息响应(Retrieve UE context response)消息，其中，Retrieve UE context response消息携带终端设备的上下文信息。该场景可以认为目标接入网设备成功找到I-RNTI对应的接入网设备。
或者，响应消息可以是获取终端设备上下文信息失败(Retrieve UE context failure)消息。若锚点接入网设备验证终端设备失败，锚点接入网设备可以发送Retrieve UE context failure消息；该场景可以认为目标接入网设备未成功找到I-RNTI对应的接入网设备，也 就是未成功找到锚点接入网设备。
或者，响应消息可以是获取终端设备上下文信息失败(Retrieve UE context failure)消息。若锚点接入网设备成功验证终端设备，但是确定继续维护终端设备的上下文信息或者确定释放终端设备到idle态，锚点接入网设备可以发送Retrieve UE context failure消息，此时Retrieve UE context failure消息携带锚点接入网设备生成的RRC释放(RRC Release)消息，目标接入网设备可以向终端设备透传或转发该RRC Release消息。该场景可以认为目标接入网设备成功找到I-RNTI对应的接入网设备。
接入网设备可以根据I-RNTI规则确定I-RNTI的格式。目前，接入网设备的I-RNTI规则可以改变，使得接入网设备在根据I-RNTI对终端设备进行RRC恢复流程时容易出现错误。
基于此，本申请实施例提供一种通信方法及装置，可以解决接入网设备的I-RNTI规则改变导致通信错误的问题。其中，方法和装置是基于同一发明构思的，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
应理解，本申请实施例中“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A、B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一(项)个”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a、b或c中的至少一项(个)，可以表示：a，b，c，a和b，a和c，b和c，或a、b和c，其中a、b、c可以是单个，也可以是多个。
需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
本申请实施例中所涉及的“I-RNTI规则”也可以称为“I-RNTI格式”、“I-RNTI的划分规则”、“I-RNTI参考配置文件(I-RNTI reference profile)”等，当然也可以命名为其他，只要该信息可以具有确定I-RNTI格式的特征，可以认为是本申请实施例所述的“I-RNTI规则”。
本申请实施例中目标接入网设备为终端设备发起RRC恢复的接入网设备。源接入网设备为配置终端设备进入inactive态的接入网设备，或者，终端设备进入inactive态之前最后接入的接入网设备，源接入网设备也可以称为锚点接入网设备。
下面结合附图对本申请提供的通信方法进行具体说明。
实施例一：
如图4所示，为本申请实施例提供的一种通信方法。该方法具体可以包括：
S401，第二接入网设备向第一接入网设备发送消息1，消息1指示第二接入网设备的第一I-RNTI规则。
相应的，第一接入网设备接收来自第二接入网设备的消息1。
一种可能的实施例中，第二接入网设备可以在更新I-RNTI规则后，向第一接入网设备发送消息1，以指示更新后的I-RNTI规则为第一I-RNTI规则。
一种示例性说明中，在终端设备恢复RRC连接的流程中，第一接入网设备可以是终端设备发起RRC恢复流程的目标接入网设备，第二接入网设备可以是保存终端设备的上下文信息的源接入网设备。
第一I-RNTI规则可以用于第一接入网设备确定I-RNTI中携带的接入网设备标识信息。
示例性的，第一I-RNTI规则可以包括：接入网设备标识信息的相关信息，接入网设备标识信息的相关信息用于第一接入网设备确定I-RNTI中携带的接入网设备标识信息。
一个示例中，接入网设备标识信息的相关信息用于指示接入网设备标识信息的比特数量。例如，接入网设备标识信息的相关信息可以为具体值，如20bit、12bit等。或者，接入网设备标识信息的相关信息也可以为相对值，例如一半、
Figure PCTCN2022089642-appb-000001
等，通过相对值可以指示接入网设备标识信息的比特数量与全局接入网设备标识信息的比特数量的比例关系，以接入网设备标识信息的相关信息可以为
Figure PCTCN2022089642-appb-000002
为例，指示接入网设备标识信息的比特数量是全局接入网设备标识信息的比特数量的
Figure PCTCN2022089642-appb-000003
I-RNTI中携带的接入网设备标识信息又可以称为本地接入网设备标识信息，比如，local RAN node ID，全局接入网设备标识信息可以为global RAN node ID。
可选的，接入网设备标识信息在全局接入网设备标识信息中的比特位置可以是第一接入网设备根据第一RNTI规则确定的，或者，也可以是预设的，或者协议规定的。
在上述示例中，第一接入网设备可以根据接入网设备标识信息的相关信息以及第二接入网设备的全局接入网设备标识信息确定第二接入网设备的接入网设备标识信息。
另一个示例中，接入网设备标识信息的相关信息可以为第二接入网设备的接入网设备标识信息。
此外，第一I-RNTI规则还可以包括以下至少一项：终端设备标识的相关信息、公共陆地移动网络(public land mobile network，PLMN)的相关信息、无线接入技术/系统的相关信息、I-RNTI规则的相关信息。
示例性的，终端设备标识的相关信息用于指示终端设备标识信息的比特数量。PLMN的相关信息用于指示PLMN信息的比特数量。无线接入技术/系统的相关信息用于指示无线接入技术/系统信息的比特数量。I-RNTI规则的相关信息用于指示I-RNTI规则序号或索引信息的比特数量。
可选的，第一I-RNTI规则与I-RNTI的比特数或者I-RNTI的长度类型对应。消息1中可以指示I-RNTI的长度类型和对应的第一I-RNTI规则。
作为一个可能的示例，消息1中指示如下I-RNTI规则信息：
Figure PCTCN2022089642-appb-000004
当I-RNTI长度为40bit时，第一I-RNTI规则可以指示local RAN node ID为20bit。假设协议规定global RAN node ID的最低位比特携带local RAN node ID，第一接入网设备可以根据第一I-RNTI规则中local RAN node ID的长度信息和第二接入网设备的global RAN node ID确定local RAN node ID。又假设协议规定I-RNTI的最低位比特携带local RAN node ID，则第一接入网设备可以确定I-RNTI长度为40时，I-RNTI从低到高的前20比特为local RAN node ID。根据上述机制，使得第一接入网设备可以确定第二接入网设备的local RAN node ID，以及确定接收到的I-RNTI中的local RAN node ID。若该两个local RAN node ID相同，第一接入网设备可以根据对应的global RAN node ID确定第二接入网设备 可能为该I-RNTI对应的终端设备的源/锚点网络设备。当I-RNTI长度为24bit时，第一I-RNTI规则可以指示local RAN node ID为12bit。第一接入网设备对应的操作可以参考I-RNTI长度为24bit时的描述，此处不再赘述。
在该示例中，第二接入网设备可以向第一接入网设备指示长本地接入网标识信息的长度，和/或，短本地接入网设备标识信息的长度。
作为另一个可能的示例，第一I-RNTI规则可以携带local RAN node ID的具体内容，例如，消息1中可以指示如下I-RNTI规则信息：

当I-RNTI长度为40bit时，第一I-RNTI规则携带第二接入网设备的长local RAN node ID，比如记为local RAN node ID1-1，local RAN node ID1-1为第二接入网设备的长度为20bit的local RAN node ID。当I-RNTI长度为24bit时，第一I-RNTI规则携带第二接入网设备的短local RAN node ID，比如记为local RAN node ID1-2，local RAN node ID1-2为第二接入网设备的长度为12bit的local RAN node ID。
在该示例中，第二接入网设备可以向第一接入网设备指示长本地接入网设备标识信息，和/或，短本地接入网设备标识信息。可选的，第二接入网设备可以向第一接入网设备指示长本地接入网标识信息的长度，和/或，短本地接入网设备标识信息的长度。
应理解，下文涉及的“I-RNTI规则”与“第一I-RNTI规则”类似，具体可以参阅以上第一I-RNTI规则的相关描述，重复之处不再赘述。
一种示例性说明中，消息1指示第一I-RNTI规则的方式可以是：携带第一I-RNTI规则的具体内容，或者，消息1也可以携带第一I-RNTI规则的序号、索引信息或标识。可选的，该序号、标识或者索引信息对应的I-RNTI规则可以是协议预定义的，或者接入网设备间交互的，或者接入网设备从其它网络设备(比如，运营和管理(operation and management，OAM)设备)获取的。例如，协议定义了多个I-RNTI规则，每个I-RNTI规则对应一个索引，消息1可以携带第一I-RNTI规则的索引。
一种示例性说明中，消息1为接口建立请求消息，比如X2 setup request消息，Xn setup request消息或者其它消息。
可选的，S401之后，可以执行S402。
S402，第一接入网设备确定第一I-RNTI规则与其他接入网设备的I-RNTI规则存在冲突。
一种可能的实现方式中，第一接入网设备在基于第一I-RNTI规则确定I-RNTI携带的本地接入网设备标识信息关联到N个可能的接入网设备时，确定第一I-RNTI规则与该多个可能的接入网设备中第二接入网设备以外的接入网设备的I-RNTI规则存在冲突，其中，N为大于1的整数。可选的，N可以是预设的，也可以是协议规定的，或者也可以是第一接入网设备确定，例如，第一接入网设备基于自身能力确定N的取值等。那么，可以执行S403。
在一些实施例中，在步骤S402之前，第二接入网设备可以向第一接入网设备发送第 三信息，第三信息用于指示是否允许第一接入网设备辅助第二接入网设备调整I-RNTI规则。
示例性的，“允许第一接入网设备辅助第二接入网设备调整I-RNTI规则”可以理解为允许第一接入网设备确定第二接入网设备的I-RNTI规则与其他接入网设备的I-RNTI规则是否存在冲突。或者，也可以理解为允许第一接入网设备在第二接入网设备的I-RNTI规则与其他接入网设备的I-RNTI规则存在冲突时，执行S403。
可以理解的是，如果第一接入网设备确定第一I-RNTI规则与其他接入网设备的I-RNTI规则不存在冲突，那么第一接入网设备可以维护第二接入网设备的第一I-RNTI规则，从而在终端设备向第一接入网设备发起RRC恢复流程时，第一接入网设备可以根据第一I-RNTI规则确定终端设备的I-RNTI携带的本地接入网设备标识信息，从而可以根据本地接入网设备标识信息确定第二接入网设备。
可选的，S403，第一接入网设备触发第二接入网设备更新I-RNTI规则。
一种实现方式中，第一接入网设备可以向第二接入网设备发送消息2，消息2指示第二接入网设备更新I-RNTI规则。
在该实现方式中，第二接入网设备在接收到消息2后，可以向第一接入网设备发送更新后的I-RNTI规则。如图5所示。
示例性的，消息2携带如下信息中至少一项：第一信息、第二信息，其中，第一信息用于指示第二接入网设备更新I-RNTI规则，第二信息用于指示I-RNTI规则的更新要求。
一种可能的实施方式中，第二接入网设备更新I-RNTI规则的过程可以为：第二接入网设备在接收到消息2后，可以重新确定当前的I-RNTI规则，并通知第一接入网设备，第一接入网设备可以再次确定该I-RNTI规则是否与其他接入网设备的I-RNTI规则冲突，若冲突，则通知第二接入网设备，直到第二接入网设备的I-RNTI规则与其他接入网设备的I-RNTI规则不存在冲突。
其中，I-RNTI规则的更新要求可以包括I-RNTI规则的具体内容，例如，第一接入网设备期望的I-RNTI规则。或者，I-RNTI规则的更新要求也可以包括I-RNTI规则的约束条件，例如，第一接入网设备期望的I-RNTI规则需要满足的条件等。
一种可能的实施方式中，第一接入网设备根据与第一I-RNTI规则冲突的I-RNTI规则确定I-RNTI规则的更新要求。
另一种可能的实施方式中，第一接入网设备也可以根据自身维护的I-RNTI规则(包括第一接入网设备的I-RNTI规则以及其他接入网设备的I-RNTI规则)确定I-RNTI规则的更新要求。
另一种实现方式中，第一接入网设备可以向运营和管理(Operation and management，OAM)实体发送消息3，消息3用于指示I-RNTI规则存在冲突。
示例性的，消息3可以携带第一I-RNTI规则的信息，例如，消息3可以携带第一I-RNTI规则的具体内容，也可以携带第一I-RNTI规则的序号、索引等标识信息。
或者，消息3可以携带第二接入网设备的标识信息。一种可能的示例中，OAM实体保存接入网设备与I-RNTI规则之间的对应关系，OAM可以根据消息3携带的第二接入网设备的标识信息确定存在冲突的I-RNTI规则。
或者，消息3也可以携带第一I-RNTI规则的信息以及第二接入网设备的标识信息。
此外，消息3还可以携带其他接入网设备的I-RNTI规则的信息和其他接入网设备的 标识信息中的至少一项，该其他接入网设备为与第二接入网设备的I-RNTI规则发生冲突的接入网设备，如第三接入网设备。
在该实现方式中，OAM实体在接收到消息3后，可以对存在冲突的I-RNTI规则进行更新，使得第二接入网设备的I-RNTI规则与其他接入网设备的I-RNTI规则不存在冲突。
例如，以第二接入网设备的I-RNTI规则与第三接入网设备的I-RNTI规则冲突为例，OAM实体可以更新第二接入网设备的I-RNTI规则，并向第二接入网设备发送更新后的I-RNTI规则，其中，第二接入网设备更新后的I-RNTI规则与第三接入网设备的I-RNTI规则不存在冲突。
进一步的，第二接入网设备可以向第一接入网设备发送更新后的I-RNTI规则。
又例如，以第二接入网设备的I-RNTI规则与第三接入网设备的I-RNTI规则冲突为例，OAM实体可以更新第三接入网设备的I-RNTI规则，并向第三接入网设备发送更新后的I-RNTI规则，其中，第三接入网设备更新后的I-RNTI规则与第二接入网设备的I-RNTI规则不存在冲突。
再例如，OAM实体还可以更新第二接入网设备的I-RNTI规则和第三接入网设备的I-RNTI规则，使得第二接入网设备更新后的I-RNTI规则与第三接入网设备更新后的I-RNTI规则不冲突。
在上述另一种实现方式中，在步骤S401之前，OAM实体可以向第二接入网设备发送允许选择的至少一个I-RNTI规则。第二接入网设备可以根据该至少一个I-RNTI规则确定第一I-RNTI规则作为第二接入网设备当前的I-RNTI规则，如图6所示。可选的，本申请实施例可以应用于相邻接入网设备间的I-RNTI规则的交互。应理解，本申请实施例一对第二接入网设备向第一接入网设备发送I-RNTI规则的过程进行了说明，第一接入网设备与第二接入网设备之间可以相互发送I-RNTI规则，重复之处不再赘述。一种示例性说明中，第一接入网设备在接收到第二接入网设备的第一I-RNTI规则后，可以向第二接入网设备发送第一接入网设备当前的I-RNTI规则。例如，第一接入网设备接收第二接入网设备发送的消息1。第一接入网设备向第二接入网设备发送消息4。消息4中携带第一接入网设备当前的I-RNTI规则。比如消息1可以为接口建立请求消息，消息4为接口建立响应消息。比如，消息1可以为X2 setup request消息，Xn setup request消息或者其它请求消息，对应的，消息4可以为X2 setup response消息，Xn setup response消息或者其它响应消息。
通过本申请实施例一所述的方案，接入网设备可以调整邻站的I-RNTI规则，例如，当接入网设备发现基于邻站的I-RNTI规则无法合理的确定锚点接入网设备时，可以辅助邻站修改I-RNTI规则，从而可以提高目标接入网设备确定锚点接入网设备的准确性，一方面，可以在一定程度上避免在基于I-RNTI确定锚点接入网设备时遗漏接入网设备，从而可以提高终端设备恢复RRC连接的成功率，另一方面，也可以在一定程度上避免基于I-RNTI确定出过多的接入网设备，从而可以节省信令开销。
实施例二：
如图7所示，为本申请实施例提供的另一种通信方法。该方法具体可以包括：
S701，第二接入网设备更新I-RNTI规则。
示例性的，更新I-RNTI规则的原因可以是基于原来的I-RNTI规则确定的接入网设备的数量超过阈值，或者，也可以是为了更合理的配置inactive态的终端设备，当然，也可 以为其他更新原因，这里不做具体限定。
可选的，第二接入网设备可以向第一接入网设备发送更新I-RNTI规则的原因，也可以不发送，这里不做具体限定。示例性的，第二接入网设备可以在第一消息中携带更新I-RNTI规则的原因。
需要说明的是，步骤S701可以是一个可选的步骤。
S702，第二接入网设备向第一接入网设备发送第一消息，第一消息用于指示第二接入网设备的至少两个I-RNTI规则保持有效。
相应的，第一接入网设备接收来自第二接入网设备的第一消息。
示例性的，该至少两个I-RNTI规则可以包括第二接入网设备更新之后的第一I-RNTI规则以及第二接入网设备更新之前的第二I-RNTI规则。例如，第一消息可以指示第二接入网设备更新后的I-RNTI规则为第一I-RNTI规则，并指示第二I-RNTI规则保持有效。具体的，第一I-RNTI规则可以包括至少一个I-RNTI规则。第二I-RNTI规则也可以包括至少一个I-RNTI规则。
一个可能的示例中，第一消息可以携带第一I-RNTI规则以及第一指示信息，第一指示信息用于指示第二I-RNTI规则是否保持有效。上述方式可以通过指示信息显式指示第二I-RNTI规则是否保持有效。可以理解的，若第二I-RNTI规则包括至少两个I-RNTI规则，第一消息可以包括至少一个第一指示信息，其中，一个第一指示信息可以关联第二I-RNTI规则中的一个或多个I-RNTI规则。例如，第一消息可以携带每个I-RNTI规则对应的第一指示信息。作为一种实现方式，第一指示信息可以为至少一个比特，该至少一个比特中的比特分别对应第二I-RNTI规则中的I-RNTI规则。
可选的，第一指示信息与I-RNTI的比特数或者I-RNTI的长度类型对应。第一消息中可以指示I-RNTI的长度类型和对应的第一指示信息。
作为一个可能的示例，以第二I-RNTI规则中有2个I-RNTI规则为例，第一消息中指示如下信息：
Figure PCTCN2022089642-appb-000006
假设第一指示信息为01时指示第1个I-RNTI规则有效，第2个I-RNTI规则无效，第一指示信息为10时指示第1个I-RNTI规则无效，第2个I-RNTI规则有效，根据上述格式的第一消息可知，full I-RNTI(即I-RNTI的长度为40bit)对应的第一指示信息为01，则第一接入网设备在接收到的第一消息后可以保持第二I-RNTI规则中的第1个full I-RNTI规则有效以及第2个full I-RNTI规则无效。short I-RNTI(即I-RNTI的长度为24bit)对应的第一指示信息为10，则第一接入网设备在接收到的第一消息后可以保持第二I-RNTI规则中的第1个short I-RNTI规则无效以及第2个short I-RNTI规则有效。
应理解，上述示例仅是一种举例说明，第一指示信息与I-RNTI的比特数或者I-RNTI的长度类型，和/或I-RNTI规则的数量的对应关系也可以为其他，这里不再一一列举。
另一个可能的示例中，第一消息可以携带第一I-RNTI规则以及第二I-RNTI规则。上述方式通过在第一消息中同时携带第一I-RNTI规则以及第二I-RNTI规则，从而可以隐式 指示第二I-RNTI规则保持有效。
又一个可能的示例中，第一消息可以指示第一接入网设备增加第一I-RNTI规则。上述方式通过在第一消息中指示增加第一I-RNTI规则，从而可以隐式指示第二I-RNTI规则保持有效。举例说明，第一消息中可以指示如下信息：
第一消息  
>增加(add)  
>>第一I-RNT规则  
作为一种可能的实现方式，在步骤S701之前，第二接入网设备向第一接入网设备发送第二I-RNTI规则。
可选的，在步骤S702之后，第一接入网设备也可以确定该至少两个I-RNTI规则中的部分I-RNTI规则失效。
例如，可以是第一接入网设备判定第二I-RNTI规则失效。如第一接入网设备在第二I-RNTI规则对应的定时器超时时确定第二I-RNTI规则失效，定时器可以记录第二I-RNTI规则的有效时间。可选的，第一消息中还可以携带时间信息，用于指示第二I-RNTI规则的有效时间。
或者，也可以是第二接入网设备指示第二I-RNTI规则失效。如当第二接入网设备释放基于第二I-RNTI规则分配I-RNTI的全部终端设备的上下文信息时，第二接入网设备可以向第一接入网设备指示第二I-RNTI规则失效。比如，第二接入网设备释放基于第二I-RNTI规则分配I-RNTI的全部终端设备的上下文信息的实现方式可以为：第二接入网设备删除基于第二I-RNTI规则分配I-RNTI的终端设备的上下文信息，和/或，转移基于第二I-RNTI规则的终端设备的上下文信息到其他接入网设备。
以该至少两个I-RNTI规则可以包括第二接入网设备更新之后的第一I-RNTI规则以及第二接入网设备更新之前的第二I-RNTI规则为例，第一接入网设备可以接收来自第二接入网设备的第二消息，第二消息指示第二I-RNTI规则失效，或者，第二消息指示第一I-RNTI规则保持有效。
示例性的，第二消息携带第二指示信息，第二指示信息用于指示第二I-RNTI规则失效，该方式通过指示信息显示指示第二I-RNTI规则失效。
或者，第二消息携带第一I-RNTI规则，该方式中，通过在第二消息未指示第二I-RNTI规则有效时隐式指示第二I-RNTI规则失效。
或者，第二消息携带第一I-RNTI规则和第二指示信息。
或者，第二消息携带第二I-RNTI规则，以及指示第二I-RNTI规则失效或者指示第一接入网设备释放第二I-RNTI规则。
可以理解的，本申请实施例以第二消息指示第二I-RNTI规则的失效为例进行描述，可选的，第二消息中也可以指示新的第三I-RNTI规则，具体的可以参考第一消息中的指示第一I-RNTI规则的相关描述，此处不再赘述。作为一个可能的示例，第二消息中指示如下信息：
第一消息  
>增加(add) 可选的
>>第三I-RNT规则  
>释放/删除(release/remove) 可选的
>>第二I-RNTI规则  
可选的，第二指示信息与I-RNTI的比特数或者I-RNTI的长度类型对应。第二消息中可以指示I-RNTI的长度类型和对应的第二指示信息。
作为一个可能的示例，第二消息中指示如下信息：
第二消息  
>full I-RNTI对应的第二指示信息 I-RNTI长度为40bit时
若更新前的I-RNTI规则的I-RNTI长度为40bit，第一接入网设备在接收到第二消息后可以不再维护full I-RNTI对应的第二I-RNTI规则。第二消息中未指示short I-RNTI时的第二指示信息，因此第一接入网设备在收到第二消息后，继续维护short I-RNTI对应的第二I-RNTI规则。
应理解，上述示例仅是一种举例说明，第二指示信息与I-RNTI的比特数或者I-RNTI的长度类型的对应关系也可以为其他，这里不再一一列举。
或者，第一接入网设备可以在第二I-RNTI规则对应的定时器超时，确定第二I-RNTI规则失效。
需要说明的是，步骤S702可以是一个可选的步骤。
一个可能的实施例中，第一接入网设备维护第二接入网设备的多个I-RNTI规则有效也可以不依赖于上述步骤S701，和/或，S702。在该实施例中，第二接入网设备也可以通过上述第二消息指示该多个I-RNTI规则中部分或全部I-RNTI规则失效。
可选的，S703，第一接入网设备根据第二接入网设备的至少一个有效的I-RNTI规则确定终端设备的I-RNTI对应的接入网设备。
一种示例性说明中，该第二接入网设备的至少一个有效的I-RNTI规则可以包括第一消息指示有效的至少两个I-RNTI规则中一个或多个，还可以包括在步骤S702之后第二接入网设备指示的新的有效的I-RNTI规则。比如，若S702之后，第一接入网设备确定第二I-RNTI规则有效，第一接入网设备可以根据第一I-RNTI规则，和/或，第二I-RNTI规则确定终端设备的I-RNTI对应的接入网设备。
或者，该第二接入网设备的至少一个有效的I-RNTI规则也可以不包括第一消息指示有效的至少两个I-RNTI规则，例如，第一接入网设备在S702之后，确定第一消息指示有效的至少两个I-RNTI规则均失效，则第一接入网设备在执行S703时采用的至少一个有效的I-RNTI规则可以不包括第一消息指示有效的至少两个I-RNTI规则。
或者，该第二接入网设备的至少一个有效的I-RNTI规则也可以不依赖于第一消息。例如，第一接入网设备在不依赖于S701和/或S702的方式下维护第二接入网设备的多个I-RNTI规则有效，步骤S703中所述的至少一个有效的I-RNTI规则可以包括第一接入网设备维护的该多个I-RNTI规则中的一个或多个I-RNTI规则。
可选的，S704，第一接入网设备向确定的接入网设备中的至少一个接入网设备发送获取终端设备上下文信息请求消息。
S704的具体描述可以参考步骤S302中的描述。
一种实现方式1中，第一接入网设备根据有效的I-RNTI规则确定接入网设备。若确定的接入网设备的数量大于或等于2个，第一接入网设备可以向全部接入网设备发送获取终端设备上下文信息请求消息，或者通过遍历的机制，依次向确定的接入网设备发送获取终端设备上下文信息请求消息。若第一接入网设备采用遍历的机制，第一接入网设备可以 依次向各个接入网设备发送获取终端设备上下文信息请求消息，直到成功找到I-RNTI对应的接入网设备。举例说明，第一接入网设备向第一个接入网设备发送获取终端设备上下文信息请求消息，若未成功找到I-RNTI对应的接入网设备，继续向下一个接入网设备发送获取终端设备上下文信息请求消息。以此类推，直到成功找到I-RNTI对应的接入网设备。需要说明的是，该举例说明中以第一接入网设备向第一个接入网设备发送获取终端设备上下文信息请求消息为例，但本申请实施例“第一个”并不限于一个，即第一接入网设备在同一时刻也可以向多个接入网设备获取终端设备的上下文信息。
另一种实现方式2中，第一接入网设备可以依次根据有效的I-RNTI规则确定接入网设备。若第一接入网设备根据第n个I-RNTI规则未成功找到I-RNTI对应的接入网设备，第一接入网设备根据第n+1个I-RNTI规则确定对应的接入网设备。以此类推，直到成功找到I-RNTI对应的接入网设备。若第一接入网设备根据每个I-RNTI规则确定的接入网设备的数量大于或等于2个，那么对于每个I-RNTI规则，第一接入网设备获取终端设备上下文信息时可以采用实现方式1中获取终端设备上下文信息的方式获取，当然，也可以采用其他方式，这里不做具体限定。其中n为大于等于1的整数。
举例说明，以第二接入网设备的2个有效的I-RNTI规则为例。比如，若S702之后，第一接入网设备维护第一I-RNTI规则，并继续维护第二I-RNTI规则有效，第一接入网设备可以根据第一I-RNTI规则，和/或，第二I-RNTI规则确定终端设备的I-RNTI对应的接入网设备。按照实现方式1，第一接入网设备先根据第一I-RNTI规则和第二I-RNTI规则分别确定对应的接入网设备。若确定的接入网设备的数量大于或等于2，第一接入网设备可以和确定的全部接入网设备分别执行S704，或者，可以和部分对应的接入网设备执行S704。若第一接入网设备和部分对应的接入网设备执行S704，当第一接入网设备成功找到I-RNTI对应的接入网设备，则第一接入网设备可以终止遍历。按照实现方式2，第一接入网设备可以基于第1个I-RNTI规则(可以是第一I-RNTI规则，也可以是第二I-RNTI规则)确定终端设备的I-RNTI对应的接入网设备，然后向基于该第1个I-RNTI规则确定出来的接入网设备发送获取终端设备上下文信息请求消息。若确定的接入网设备的数量大于或等于2，第一接入网设备可以和确定的全部接入网设备分别执行S704，或者，可以和部分对应的接入网设备执行S704。若第一接入网设备遍历根据第1个I-RNTI规则确定出来的接入网设备，未成功找到I-RNTI对应的接入网设备，可以继续基于第2个I-RNTI规则确定终端设备的I-RNTI对应的接入网设备。若基于第2个I-RNTI规则确定的接入网设备的数量大于或等于2，第一接入网设备的实现方式可以参考上述描述，此处不再赘述。
一种示例性说明中，若有多个接入网设备的本地接入网设备标识信息与终端设备的I-RNTI携带的本地接入网设备标识信息相同，则第一接入网设备可以根据终端设备的I-RNTI确定出多个接入网设备。
需要说明的是，在上述另一种实施方式中以第一接入网设备在遍历过程中一次基于1个I-RNTI规则获取终端设备的上下文信息，但本申请实施例并不限于一个，第一接入网设备在遍历过程中也可以一次基于多个I-RNTI规则获取终端设备的上下文信息。
本申请实施例中，目标接入网设备可以在源接入网设备的指示下维持源接入网设备的多个I-RNTI规则有效，从而在恢复终端设备的RRC连接时可以基于多个I-RNTI规则确定源接入网设备，从而可以在一定程度上避免在基于I-RNTI确定源接入网设备时遗漏接入网设备，从而可以提高终端设备恢复RRC连接的成功率，使得终端设备可以快速进入 连接态，缩短业务传输的时延。
例如，第一消息通过指示增加I-RNTI规则的方式，使得第一接入网设备在维护第二接入网设备原有I-RNTI规则的基础上进一步维护增加的I-RNTI规则，由于第二接入网设备在更新I-RNTI规则后可能存在基于原有I-RNTI规则分配I-RNTI的终端设备。通过上述方式第一接入网设备可以在恢复终端设备RRC连接时可以根据原有的I-RNTI规则和新增的I-RNTI规则确定接入网设备，从而可以在一定程度上避免遗漏接入网设备，从而可以提高终端设备恢复RRC连接的成功率。
此外，第二消息通过指示删除/释放I-RNTI规则的方式，使得第一接入网设备可以不再维护第二接入网设备原有I-RNTI规则。通过上述方式第一接入网设备可以在恢复终端设备RRC连接时可以根据新增的I-RNTI规则确定接入网设备，从而可以减少确定出的接入网设备的数量，进而可以向少量的接入网设备获取终端设备的上下文信息，可见，通过上述方式可以降低第一接入网设备的成本。
一种可能的实施方式中，第二接入网设备在向第一接入网设备指示任一I-RNTI规则之前，可以基于实施例一所述的过程与第一接入网设备进行交互，使得第二接入网设备的I-RNTI规则与其他接入网设备的I-RNTI规则不存在冲突，具体过程可以参阅实施例一所述，这里不再重复赘述。
为了便于对方案的理解，下面结合具体场景对本申请实施例二提供的方法进行描述。在如图8所示流程中，第一接入网设备可以为终端设备发起RRC恢复流程的目标接入网设备，第二接入网设备可以为保存有终端设备上下文信息的源接入网设备。
图8所示的流程可以包括：
S801，第二接入网设备向第一接入网设备发送I-RNTI规则1。
可选的，步骤S801之前，第二接入网设备与第一接入网设备可以基于实施例一所述的过程进行交互，使得I-RNTI规则1与其他接入网设备的I-RNTI规则不存在冲突。
S802，第二接入网设备配置至少一个第一终端设备进入inactive态，并基于I-RNTI规则1为该终端设备分配I-RNTI。
需要说明的是，步骤S801和S802没有严格的先后顺序，可以先执行S801再执行S802，也可以先执行S802再执行S801，或者也可以同时执行S801和S802。
S803，第二接入网设备确定将当前的I-RNTI规则更新为I-RNTI规则2。
可选的，步骤S803之前，第二接入网设备与第一接入网设备可以基于实施例一所述的过程进行交互，使得I-RNTI规则2与其他接入网设备的I-RNTI规则不存在冲突。
示例性的，更新I-RNTI规则的原因可以是基于I-RNTI规则1确定的接入网设备的数量超过阈值，或者，也可以是为了更合理的配置inactive态的终端设备，当然，也可以为其他更新原因，这里不做具体限定。
可选的，第二接入网设备可以向第一接入网设备发送更新I-RNTI规则的原因，也可以不发送，这里不做具体限定。示例性的，第二接入网设备可以在第一消息中携带更新I-RNTI规则的原因。
S804，第二接入网设备向第一接入网设备发送第一消息，该第一消息携带I-RNTI规则2，并指示I-RNTI规则1保持有效。
一个示例中，第一消息可以携带I-RNTI规则2以及第一指示信息，第一指示信息用于指示I-RNTI规则1保持有效，或者，该第一指示信息也可以指示第一接入网设备可以 根据更新之前的I-RNTI规则1确定接入网设备。
另一个示例中，第一消息可以携带I-RNTI规则1以及I-RNTI规则2。
又一个示例中，第一消息可以指示第一接入网设备增加I-RNTI规则2。
一种示例性说明中，第一消息可以是设备配置更新消息，比如ENB/NG-RAN NODE CONFIGURATION UPDATE消息，或者设备配置更新确认消息，比如ENB/NG-RAN NODE CONFIGURATION UPDATE ACKNOWLEDGE。
可选的，S804之后，可以执行S805。
S805，第一接入网设备向第二接入网设备发送第一消息的确认消息。
示例性的，第一消息的确认消息可以为设备配置更新确认消息，比如ENB/NG-RAN NODE CONFIGURATION UPDATE ACKNOWLEDGE。
S806，第二接入网设备配置至少一个第二终端设备进入inactive态，并基于I-RNTI规则2为该终端设备分配I-RNTI。
S807，终端设备1向第一接入网设备发送RRC恢复请求消息，该RRC恢复请求消息携带该终端设备1的I-RNTI。
其中，该终端设备1可以是第一终端设备，也可以是第二终端设备。
S808，第一接入网设备基于I-RNTI规则1和/或I-RNTI规则2确定该终端设备1的I-RNTI对应的接入网设备。
S809，第一接入网设备向确定的接入网设备发送上下文获取请求消息，该上下文获取请求消息用于获取终端设备1的上下文信息。
一种实现方式中，第一接入网设备基于I-RNTI规则1和I-RNTI规则2确定该终端设备1的I-RNTI对应的接入网设备，并向基于I-RNTI规则1确定的接入网设备以及基于I-RNTI规则2确定的接入网设备分别发送上下文获取请求消息。
另一种实现方式中，第一接入网设备基于I-RNTI规则1确定该终端设备的I-RNTI对应的接入网设备，并向基于I-RNTI规则1确定的接入网设备发送上下文获取请求消息。若成功找到I-RNTI对应的接入网设备，则继续RRC恢复流程，具体可以参阅图3中S303所述。若未成功找到I-RNTI对应的接入网设备，则基于I-RNTI规则2确定该终端设备的I-RNTI对应的接入网设备，并向基于I-RNTI规则2确定的接入网设备发送上下文获取请求消息。
应理解，上述实现方式仅以先基于I-RNTI规则1获取终端设备的上下文信息，后基于I-RNTI规则2获取终端设备的上下文信息为例，在具体实施中，也可以先基于I-RNTI规则2获取终端设备的上下文信息，后基于I-RNTI规则1获取终端设备的上下文信息，这里不对I-RNTI规则的先后顺序进行具体限定。
S810，第二接入网设备向第一接入网设备发送第二消息，第二消息指示I-RNTI规则1失效。
示例性的，第二消息携带第二指示信息，第二指示信息用于指示I-RNTI规则1失效。或者，第二消息只携带I-RNTI规则2。或者，第二消息携带第二指示信息和I-RNTI规则2。或者，第二消息携带I-RNTI规则1，以及指示I-RNTI规则1失效或者指示第一接入网设备释放I-RNTI规则1。
一种示例性说明中，第二消息可以是设备配置更新消息，比如ENB/NG-RAN NODE CONFIGURATION UPDATE消息，或者设备配置更新确认消息，比如ENB/NG-RAN NODE  CONFIGURATION UPDATE ACKNOWLEDGE。
一种实施方式中，第二接入网设备可以释放基于I-RNTI规则1分配I-RNTI的全部终端设备的上下文信息时，向第一接入网设备发送第二消息。
