随机接入报告方法、装置及存储介质 技术领域
本公开涉及通信领域，特别涉及一种随机接入报告方法、装置及存储介质。
背景技术
第三代合作伙伴计划(third Generation Partnership Project，3GPP)在新空口(New Radio，NR)中引入了双连接载波聚合(Dual Connectivity Carrier Aggregation，DCCA)的概念，使支持5G的用户终端(User Equipment，UE)可以同时连接两个基站。
在DCCA场景下，终端可以同时连接一个演进的通用陆地无线接入(Evolved Universal Terrestrial Radio Access，E-UTRA)基站和一个NR基站，可称为多无线接入技术双连接(Multi-Radio Dual Connectivity，MR-DC)，其中，一个基站作为主节点(Master Node，MN)，一个基站作为辅节点(Secondary Node，SN)；或者，用户终端可以同时连接两个NR基站，称为新空口双连接(New Radio-Dual Connectivity，NR-DC)，其中，主节点和辅节点都为NR基站。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书 中所详述的、本公开的一些方面相一致的装置和方法的例子。
图1示出了本申请一个示例性实施例提供的双连接场景下的网络架构图。
如图1所示，在终端110同时连接第一基站120和第二基站130的情况下，第一基站120为主节点(Master Node，MN)，第二基站130为辅节点(Secondary Node，SN)，终端110首先接入作为主节点的第一基站120，然后根据需要添加作为辅节点的第二基站130。其中，主节点也称为“锚点”，作为主节点的第一基站120负责跟核心网140的控制面进行交互。
不论是第一基站120还是第二基站130，基站内部都支持多个载波/小区进行载波聚合。因此，对作为主节点的第一基站120的至少两个小区，称为主小区组(Master Cell Group，MCG)121，主小区组121中包含主小区(Primary Cell，Pcell)1211和多个辅小区(Secondary Cell，Scell)1212。对作为辅节点的第二基站130的至少两个小区，称为辅小区组(Secondary Cell Group，SCG)，辅小区组131包含主辅小区(Primary Secondary Cell，PSCell)1311，和多个辅小区1312。
下面针对四种双连接进行详细说明：
1、EN-DC场景：该连接方式中，用户终端同时连接E-UTRA基站和NR基站。其中，E-UTRA基站(也称为LTE基站)为主节点，NR基站为辅节点，主节点连接到演进的分组核心网(Evolved Packet Core，EPC)；
2、NGEN-DC场景：该连接方式中，用户终端同时连接E-UTRA基站和NR基站。其中，E-UTRA基站为主节点，NR基站为辅节点，主节点连接到5G核心网(5G Core Network，5CG)；
3、NE-DC(New Radio E-UTRA Dual Connectivity with NR Connected to 5GC)场景：该连接方式中，用户终端同时连接E-UTRA基站和NR基站，其中，NR基站为主节点，E-UTRA基站为辅节点，主节点连接到5CG；
4、NR-DC(New Radio Dual Connectivity with NR Connected to 5GC)场景：该连接方式中，用户终端同时连接两个NR基站，其中，一个NR基站为主节点，另一个NR基站为辅节点，主节点连接到5GC。
在相关协议中，RAN3已经完成网络接口信令交互相关的工作，以支持上述四种双连接场景下的SN RACH Report，然而对于RAN2来说，目前仅支持NR-DC场景下的SN RACH Report，尚不支持EN-DC、NGEN-DC和NE-DC场景下SN RACH Report。因此为解决EN-DC场景和NGEN-DC场景下支持SN RACH Report这一技术问题，本申请提供了随机接入报告方法，如下实施例所示。
关于信令无线承载3(Signalling Radio Bearer3，SRB3)，SRB3用于终端和辅节点进行信令交互。当辅节点为EN-DC场景/NGEN-DC场景/NR-DC场景下的基站时，可以配置终端和辅节点建立SRB3，使辅节点的无线资源控制(Radio Resource Control，RRC)协议数据单元(Protocol Data Unit，PDU)可以在终端和辅节点之间直接发送，辅节点对应的RRC PDU可以直接发送到终端进行辅节点RRC重配置，无需和主节点进行协调。若在终端和辅节点之间配置了SRB3，则可以从终端直接上报移动性测量报告给辅节点。
图2示出了本公开一个示例性实施例提供的通信系统的框图，该通信系统可以包括：接入网22、用户终端24和核心网设备26。
接入网22中包括若干个接入网设备220。接入网设备220可以是基站，所述基站是一种部署在接入网中用以为用户终端(简称为“终端”)24提供无线通信功能的装置。基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在长期演进(Long Term Evolution，LTE)系统中，称为eNodeB或者eNB；在5G NR系统中，称为gNodeB或者gNB。随着通 信技术的演进，“基站”这一描述可能会变化。该接入网22可以采用上述NGEN-DC和EN-DC中的至少之一双连接技术构建。
核心网中包括若干个核心网设备26。核心网的功能是负责信息在系统内部的交换、路由、用户数据管理、安全等以及与其他通信系统的信息交换传输。5GC的主要网络功能包括：接入和移动性管理功能(Access and Mobility management Function，AMF)、会话管理功能(Session Management Function，SMF)、用户面功能(User Plane Function，UPF)、网络存储库功能(Network Repository Function，NRF)、网络公开功能(Network Exposure Function，NEF)、统一数据管理(Unified Data Management，UDM)、位置管理功能(Location Management Function，LMF)、以及其它网络功能。
为方便本公开实施例中的描述，上述为用户终端24提供无线通信功能的装置统称为网络设备。示例性的，网络设备包括接入网设备220和核心网设备26中的至少一种。
用户终端24可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备，移动台(Mobile Station，MS)，终端设备(terminal device)等等。为方便描述，上面提到的设备统称为用户终端。接入网设备220与用户终端24之间通过某种空口技术互相通信，例如Uu接口。
本公开实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile Communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)系统、先进的长期演进(Advanced long Term Evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to Unlicensed spectrum，LTE-U)系统、NR-U系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，车辆间(Vehicle to Vehicle，V2V)通信以及车联网(Vehicle to Everything，V2X)系统等。本公开实施例也可以应用于这些通信系统。
图3示出了本公开一个示例性实施例提供的随机接入报告方法的流程图，该方法应用于图2所示的通信系统中，由终端执行，该方法包括：
步骤310：执行以下至少一项操作：

在一些实施例中，上述方法针对以下任意一种双连接场景：连接到5GC的E-UTRA和NR双连接NGEN-DC；连接到EPC的E-UTRA和NR双连接EN-DC。
NGEN-DC场景下，该连接方式中，用户终端同时连接E-UTRA基站和NR基站。其中，E-UTRA基站为主节点，NR基站为辅节点，主节点连接到5GC。
EN-DC场景下，该连接方式中，用户终端同时连接E-UTRA基站和NR基站。其中，E-UTRA基站为主节点，NR基站为辅节点，主节点连接到EPC。
在一些实施例中，终端仅记录NR小区的RA信息，包括将以下至少一项记录到RA报告变量(VarRA-Report)：
·如果终端在SCG中的至少一个小区发起随机接入，确定记录该小区的RA信息；
例如，如果终端在SCG中的主辅小区发起随机接入，确定记录主辅小区的RA信息；或者，如果终端在SCG中的辅小区发起随机接入，确定记录该辅小区的RA信息；或者，如果终端在SCG中的主辅小区和辅小区发起随机接入，确定记录该主辅小区和辅小区的RA信息。
·如果终端在MCG中的至少一个小区发起随机接入，确定不记录该小区的RA信息。
例如，如果终端在MCG中的主小区发起随机接入，确定不记录主小区的RA信息；或者，如果终端在MCG中的辅小区发起随机接入，确定不记录该辅小区的RA信息；或者，如果终端在MCG中的主小区和辅小区发起随机接入，确定不记录该主小区和辅小区的RA信息。
示意性的，NR小区的RA信息中包括SCG小区的RA信息。
在一些实施例中，“NR小区”和“SCG小区”为相同概念。
在一些实施例中，上述SCG小区的RA信息，记录在RA报告变量中。
可选地，终端直接上报SCG小区的RA信息；或者，终端将储存在RA报告变量中的SCG小区的RA信息进行上报，对此不加以限定。
可选地，上述SCG小区的RA信息包括SCG主辅小区的RA信息和/或SCG辅小区的RA信息。
在一些实施例中，向辅节点上报SCG小区的RA信息；和/或，向辅节点上报MCG小区的RA信息。

可选地，上述MCG小区的RA信息包括MCG主小区的RA信息和/或MCG辅小区的RA信息。
可选地，终端上报RA信息包括如下至少一项：
第一，终端自行上报。
在一些实施例中，终端自行向辅节点上报可用的SCG小区的RA信息，也即，不依靠接收辅节点发送的RA信息上报请求，终端自行将可用的SCG小区的RA信息进行上报。
在一些实施例中，终端自行向辅节点上报可用的MCG小区的RA信息和/或SCG小区的RA信息，也即，不依靠接收辅节点发送的RA信息上报请求，终端自行将可用的MCG小区的RA信息和/或SCG小区的RA信息上报至辅节点。其中，辅节点将MCG小区的RA信息发送给主节点。
第二，接收RA信息上报请求后进行上报。
在一些实施例中，响应于接收到辅节点发送的RA信息上报请求，向辅节点上报RA信息。
在一个可实现的情况下，RA信息上报请求实现为独立的MN RA信息上报请求和/或独立的SN RA信息上报请求。
示意性的，响应于接收到RA信息上报请求，向辅节点上报SCG小区和/或MCG小区的RA信息，RA信息上报请求用于请求终端上报SCG小区和/或MCG小区的RA信息。
例如，终端接收到辅节点发送的独立的MN RA信息上报请求，向辅节点上报可用的MCG小区的RA信息；终端接收到辅节点发送的独立的SN RA信息上报请求，向辅节点上报可用的SCG小区的RA信息。
在一个可实现的情况下，RA信息上报请求不区分为独立的MN RA信息上报请求和独 立的SN RA信息上报请求。
例如，预定义辅节点发送的SN RA信息上报请求，用于请求终端仅上报SCG小区的RA信息。当终端接收到RA信息上报请求，仅向辅节点上报SCG小区的RA信息。
在一些实施例中，响应于接收到辅节点发送的RA信息上报请求，向辅节点上报可用的SCG小区和/或MCG小区的RA信息，RA信息上报请求用于请求终端上报SCG小区和/或MCG小区的RA信息。其中，RA信息上报请求用于请求哪一种小区的RA信息，可以由协议预定义，或可以由终端根据RA报告变量的缓存内容确定，或可以由RA信息上报请求内的指示比特确定，本实施例不加以限定。
例如，终端在接收到的辅节点发送的RA信息上报请求，根据RA报告变量的缓存内容，向辅节点上报可用的SCG小区和/或MCG小区的RA信息。
又例如，终端接收辅节点发送的RA信息上报请求，RA信息上报请求中携带指定比特，用于指示RA信息上报请求中请求上报的RA信息。
可选地，当RA信息上报请求中携带指定比特为第一取值时，终端接收辅节点发送的RA信息上报请求，向辅节点上报可用的SCG小区的RA信息。
可选地，当RA信息上报请求中携带指定比特为第二取值时，终端接收辅节点发送的RA信息上报请求，向辅节点上报可用的MCG小区的RA信息。
可选地，当RA信息上报请求中携带指定比特为第三取值时，终端接收辅节点发送的RA信息上报请求，向辅节点上报可用的MCG小区的RA信息和SCG小区的RA信息。
上述第一取值、第二取值和第三取值不同。
在一些实施例中，上述RA信息上报请求携带在UE信息请求消息；上述RA信息携带在UE信息响应消息。
在一些实施例中，终端还上报能力信息，能力信息用于指示终端是否支持SCG小区的RA信息上报。可选地，终端在上报能力信息之前，辅节点向终端发送能力请求，或能力上报指示。
在一些实施例中，终端还上报可用性指示，可用性指示用于指示终端有可用的NR小区的RA信息。
在一些实施例中，终端在RA信息成功上报后，将成功上报的RA信息丢弃；或，在延时第一时长后，将RA信息丢弃。示例性的，延时第一时长的起始时间为：RA信息的记录时间，或，RA信息的上报时间，或RA信息的成功上报时间。第一时长为预定义，或预配置，或动态配置的值，比如第一时长为48小时。
在一些实施例中，上述RA信息上报请求和/或RA信息通过SRB3传输。
综上所述，本实施例提供的方法，执行以下至少一项操作：仅记录SCG小区的RA信息；向辅节点上报RA信息。该方法用于支持终端在NGEN-DC场景和EN-DC场景下执行包括记录SCG小区的RA信息和上报RA信息中至少一项操作。
