本申请实施例涉及通信领域，尤其涉及一种信息处理方法、基站以及终端。The embodiments of the present application relate to the field of communications, and in particular, to an information processing method, a base station, and a terminal.

背景技术Background technique

未来的第五代(5th Generation，5G)网络建设中，可以通过长期演进(Long Term Evolution，LTE)与新空口(New Radio，NR)***间的双连接(dual connection，DC)(简称“LTE-NR DC”)，使终端同时从LTE和NR空口获得无线资源，提高无线资源利用率，提高传输速率。In the future 5th generation (5G) network construction, you can use dual connection (DC) between Long Term Evolution (LTE) and New Radio (NR) systems (referred to as "LTE". -NR DC"), enabling the terminal to obtain radio resources from both LTE and NR air interfaces, improving radio resource utilization and increasing transmission rate.

在上述LTE-NR DC场景中，主基站与辅基站为不同制式的基站，例如主基站是LTE基站且辅基站为NR基站，该场景下，终端如何获取NR PDCP配置是一个亟待解决的问题。In the foregoing LTE-NR DC scenario, the primary base station and the secondary base station are different base stations, for example, the primary base station is an LTE base station and the secondary base station is an NR base station. In this scenario, how the terminal acquires the NR PDCP configuration is an urgent problem to be solved.

发明内容Summary of the invention

本申请实施例提供了一种信息处理方法、基站以及终端，用于解决LTE-NR DC场景下，存在的终端如何获取NR PDCP配置的问题。An embodiment of the present application provides an information processing method, a base station, and a terminal, which are used to solve the problem that a terminal existing in an LTE-NR DC scenario acquires an NR PDCP configuration.

为了解决上述问题，本申请提供以下技术方案：In order to solve the above problems, the present application provides the following technical solutions:

第一方面，本申请提供了一种信息处理方法，该方法包括：主基站从辅基站接收NR PDCP配置，以及该NR PDCP配置对应的数据无线承载(data radio bearer，DRB)的标识信息，主基站接收到NR PDCP配置和DRB的标识信息后，向终端转发该NR PDCP配置以及DRB的标识信息，其中，主基站和辅基站为不同制式的基站。从这里可以看出，在本申请第一方面中，在主基站与辅基站为不同制式的情况下，如果沿用现有LTE DC机制，主基站会因为无法解析辅基站发送的内容，从而可能导致直接丢弃。为了避免该问题在LTE-NR DC场景出现，则辅基站会通过主辅基站之间的接口直接将NR PDCP配置，以及该NR PDCP配置对应的DRB的标识信息发送给主基站，主基站不解析辅基站生成的NR PDCP配置，直接将收到的NR PDCP配置，和对应的DRB的标识信息转发给终端。In a first aspect, the present application provides an information processing method, where the method includes: receiving, by a primary base station, an NR PDCP configuration from a secondary base station, and identifying information of a data radio bearer (DRB) corresponding to the NR PDCP configuration, where After receiving the NR PDCP configuration and the ID information of the DRB, the base station forwards the NR PDCP configuration and the ID information of the DRB to the terminal, where the primary base station and the secondary base station are base stations of different standards. It can be seen from the above that in the first aspect of the present application, if the primary base station and the secondary base station are in different formats, if the existing LTE DC mechanism is used, the primary base station may not be able to resolve the content sent by the secondary base station, which may result in Discard directly. In order to prevent the problem from occurring in the LTE-NR DC scenario, the secondary base station directly transmits the NR PDCP configuration and the identification information of the DRB corresponding to the NR PDCP configuration to the primary base station through the interface between the primary and secondary base stations, and the primary base station does not resolve. The NR PDCP configuration generated by the secondary base station directly forwards the received NR PDCP configuration and the corresponding DRB identification information to the terminal.

在一种可能的实现中，主基站从辅基站接收NR PDCP配置，以及该NR PDCP配置对应的DRB的标识信息，具体是指主基站从辅基站接收包含有该NR PDCP配置的第一container(容器)，并从辅基站接收该NR PDCP配置对应的DRB的标识信息，其中，第一container与DRB的标识信息一一对应，接着，主基站再将该NR PDCP配置对应的DRB的标识信息，以及只包含有该NR PDCP配置的第一container发送终端。由此可得，在本实现中，辅基站只将生成的NR PDCP配置封装成container的形式，并发送给主基站，对于主基站而言，一方面，主基站不需要解析第一container的内容，从而不会认为接收到的第一container 为错误包，最后成功通过第一container将NR PDCP配置下发至终端，有效地解决了辅基站怎么下发配置给终端的问题。In a possible implementation, the primary base station receives the NR PDCP configuration from the secondary base station, and the identifier information of the DRB corresponding to the NR PDCP configuration, where the primary base station receives the first container that includes the NR PDCP configuration from the secondary base station. a container, and receiving, from the secondary base station, the identifier information of the DRB corresponding to the NR PDCP configuration, wherein the first container and the identifier information of the DRB are in one-to-one correspondence, and then the primary base station configures the identifier information of the DRB corresponding to the NR PDCP. And a first container transmitting terminal that only includes the NR PDCP configuration. Therefore, in the implementation, the secondary base station only encapsulates the generated NR PDCP configuration into a container and sends it to the primary base station. For the primary base station, on one hand, the primary base station does not need to parse the content of the first container. Therefore, the first container is not considered to be an error packet, and finally the NR PDCP configuration is successfully sent to the terminal through the first container, which effectively solves the problem of how the secondary base station sends the configuration to the terminal.

在一种可能的实现中，主基站从辅基站接收NR PDCP配置，以及该NR PDCP配置对应的DRB的标识信息，具体是指主基站从辅基站接收同时包含有NR PDCP配置，和该NR PDCP配置对应的DRB的标识信息的第一container，其中，NR PDCP配置与DRB的标识信息一一对应。接着，主基站再将第一container发送给终端。从这里可以看出，与上述实现不一样的地方在于，第一container除了包含有辅基站的NR PDCP配置之外，还包含该NR PDCP配置对应的DRB的标识信息，也就是说，该第一container中包含辅基站的NR PDCP配置，以及该NR PDCP配置对应的DRB的标识信息，提高了方案的多样性。In a possible implementation, the primary base station receives the NR PDCP configuration from the secondary base station, and the identifier information of the DRB corresponding to the NR PDCP configuration, specifically, the primary base station receives the NR PDCP configuration from the secondary base station, and the NR PDCP The first container of the identifier information of the corresponding DRB is configured, where the NR PDCP configuration corresponds to the identifier information of the DRB. Then, the primary base station sends the first container to the terminal. It can be seen that the difference from the above implementation is that the first container includes the NR PDCP configuration of the secondary base station, and the identifier information of the DRB corresponding to the NR PDCP configuration, that is, the first The container includes the NR PDCP configuration of the secondary base station and the identification information of the DRB corresponding to the NR PDCP configuration, which improves the diversity of the solution.

在一种可能的实现中，主基站可以从主基站与辅基站之间的接口消息，例如：辅基站增加请求确认(SgNB addition request acknowledge)消息，辅基站变更确认(SgNB modification request acknowledge)消息，辅基站触发的变更咨询消息(SgNB modification required)，辅基站修改咨询(SgNB change required)消息等来接收辅基站发送该NR PDCP配置，和该NR PDCP配置对应的DRB的标识信息。In a possible implementation, the primary base station may send an interface message between the primary base station and the secondary base station, for example, a secondary base station add request acknowledgement (SgNB addition request acknowledge) message, and a secondary base station change request acknowledgement (SgNB modification request acknowledge) message. The SgNB modification required message, the SgNB change required message, and the like, the receiving base station sends the NR PDCP configuration, and the ID information of the DRB corresponding to the NR PDCP configuration.

在一种可能的实现中，主基站还从辅基站接收第二container，该第二container中包含辅基站的空口配置，这里所讲的辅基站的空口配置不包含上述NR PDCP配置，主基站再将从辅基站接收的第二container发送给终端，另外，第二container与DRB的标识信息也一一对应。在本实现中，主基站除了将NR PDCP配置配置给终端外，还将辅基站的空口配置发送给终端，保证方案的完整性。In a possible implementation, the primary base station further receives the second container from the secondary base station, where the second container includes the air interface configuration of the secondary base station, where the air interface configuration of the secondary base station does not include the foregoing NR PDCP configuration, and the primary base station The second container received from the secondary base station is sent to the terminal, and the second container also has a one-to-one correspondence with the identification information of the DRB. In this implementation, the primary base station sends the NR PDCP configuration to the terminal, and sends the air interface configuration of the secondary base station to the terminal to ensure the integrity of the solution.

在一种可能的实现中，主基站与辅基站均使用NR PDCP，也就是说主基站与辅基站都使用NR PDCP协议。In a possible implementation, both the primary base station and the secondary base station use NR PDCP, that is, both the primary base station and the secondary base station use the NR PDCP protocol.

The method further includes: after the first base station determines that the terminal is configured with the dual connectivity function, sending a secondary station addition request message to the second base station, where the message carries the terminal supporting the NR PDCP protocol or supporting the dual connectivity function of the LTE system and the NR system. Capability information, once the second base station acquires the capability information of the terminal, and learns that the terminal supports the NR PDCP protocol or supports the dual connectivity function of the LTE system and the NR system, the second base station generates an NR PDCP configuration, and sends the NR to the terminal through the first base station. PDCP configuration. It can be seen that the method proposed in the fourth aspect is also applicable to the dual connectivity scenario of the eLTE system and the NR system.

其中，本申请实施例中所涉及的终端，可以是指向用户提供语音和/或数据连通性的无线终端，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。无线终端可以经无线接入网(radio access network，RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，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 communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)等设备。无线终端也可以称为***、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、用户设备(user device，)、或用户装备(user equipment，UE)，具体这里不做限定。The terminal involved in the embodiment of the present application may be a wireless terminal that provides voice and/or data connectivity to the user, a handheld device with a wireless connection function, or other processing device connected to the wireless modem.

在本申请实施例中，DRB是指终端与基站之间的数据无线承载，用于承载基站与终端之间传输的数据。请参阅图2，图2为本申请实施例中提供的DRB的一个示意图，由图2可知，本申请实施例提供的DRB的类型包括主小区组承载(MCG bearer)，辅小区组承载(SCG bearer)，以及分流承载(split bearer)。split bearer还包括数据锚点在主基站上的分流承载以及数据锚点在辅基站上的分流承载，其中，数据锚点在主基站上的分流承载可以称为主小区组分流承载(MCG split bearer)；数据锚点在辅基站上的分流承载可以称为辅小区组分流承载(SCG split bearer)。In the embodiment of the present application, the DRB refers to a data radio bearer between the terminal and the base station, and is used to carry data transmitted between the base station and the terminal. Referring to FIG. 2, FIG. 2 is a schematic diagram of a DRB provided in the embodiment of the present application. As shown in FIG. 2, the DRB type provided by the embodiment of the present application includes a primary cell group bearer (MCG bearer) and a secondary cell group bearer (SCG). Bearer), as well as a split bearer. The split bearer further includes a offload bearer of the data anchor point on the primary base station and a offload bearer of the data anchor point on the secondary base station, wherein the offload bearer of the data anchor point on the primary base station may be referred to as a primary cell component flow bearer (MCG split bearer) The offloaded bearer of the data anchor on the secondary base station may be referred to as a secondary cell component bearer (SCG split bearer).

具体地，所述MCG bearer是指空口协议仅位于主基站以使用主基站的传输资源的承载，因此，MCG bearer上的上行或下行数据仅通过主基站传输。所述SCG bearer是指空口协议仅位于辅基站以使用辅基站的传输资源的承载，因此，SCG bearer上的上行或下行数据仅通过辅基站传输。所述split bearer是指空口协议同时位于主基站及辅基站以同时使用主基站及辅基站的传输资源的承载，则主基站与辅基站可以同时与终端进行数据传输。进一步地，对于split bearer而言，若采用MCG split bearer，则在下行方向，由主基站的分组数据汇聚层协议(Packet Data Convergence Protocol，PDCP)层将核心网下发的下行数据分流到辅基站，并由辅基站将分流的下行数据发送给终端；在上行方向，如果上行支持分流，则主基站、辅基站分别从终端接收上行数据，辅基站再将接收到的上行数据发送给主基站，由主基站将分别从主基站和辅基站接收的上行数据进行重排序，然后再按序将收到的数据发送给核心网。若采用SCG split bearer，则在下行方向，由辅基站的PDCP层将核心网下发的下行数据分流到主基站，并由主基站将分流的下行数据发送给终端；在上行方向，如果上行支持分流，则主基站、辅基站分别从终端接收上行数据，主基站再将接收到的上行数据发送给辅基站，由辅基站将分别从主基站和辅基站接收的上行数据进行重排序，然后在再按序将收到的数据发送给核心网。可以理解，对于MCG bearer和SCG bearer，主基站上传输的数据以及辅基站上传输的数据属于不同的业务，例如，主基站上传输语音业务数据，辅基站上传输视频业务数据；对于split bearer，主基站上传输的数据以及辅基站上传输的数据属于同一类业务的不同数据，本申请实施例对此不做限定。Specifically, the MCG bearer refers to a bearer protocol in which only the primary base station uses the transmission resources of the primary base station, and therefore, uplink or downlink data on the MCG bearer is transmitted only through the primary base station. The SCG bearer refers to a bearer protocol where only the secondary base station uses the transmission resources of the secondary base station, and therefore, the uplink or downlink data on the SCG bearer is transmitted only through the secondary base station. The split bearer refers to a bearer protocol in which the primary base station and the secondary base station simultaneously use the transmission resources of the primary base station and the secondary base station, and the primary base station and the secondary base station can simultaneously perform data transmission with the terminal. Further, for the split bearer, if the MCG split bearer is used, the downlink data sent by the core network is offloaded to the secondary base station by the Packet Data Convergence Protocol (PDCP) layer of the primary base station in the downlink direction. And the secondary base station sends the downlink data of the offload to the terminal; in the uplink direction, if the uplink supports the offload, the primary base station and the secondary base station respectively receive the uplink data from the terminal, and the secondary base station sends the received uplink data to the primary base station again. The primary base station reorders the uplink data received from the primary base station and the secondary base station, and then sends the received data to the core network in sequence. If the SCG split bearer is used, in the downlink direction, the downlink data sent by the core network is offloaded to the primary base station by the PDCP layer of the secondary base station, and the downlink data of the offloaded is sent by the primary base station to the terminal; The primary base station and the secondary base station respectively receive uplink data from the terminal, and the primary base station sends the received uplink data to the secondary base station, and the secondary base station reorders the uplink data respectively received from the primary base station and the secondary base station, and then The received data is sent to the core network in sequence. It can be understood that, for the MCG bearer and the SCG bearer, the data transmitted on the primary base station and the data transmitted on the secondary base station belong to different services, for example, the voice service data is transmitted on the primary base station, and the video service data is transmitted on the secondary base station; for the split bearer, The data transmitted on the primary base station and the data transmitted on the secondary base station belong to different data of the same type of service, which is not limited in this embodiment of the present application.

示例性的，在本申请实施例中，MCG bearer、SCG bearer和split bearer的PDCP层都可以采用NR协议规定的PDCP层的格式，在本申请实施例中，NR协议规定的PDCP层可以简称为NR PDCP层。而其他协议层，如无线链路控制(radio link control，RLC)层、介质访问控制(media access control，MAC)层和物理层(physical layer，PHY)，对于上述4种承载方式而言，还是在不同制式下各自独立。For example, in the embodiment of the present application, the PDCP layer of the MCG bearer, the SCG bearer, and the split bearer may be in the format of the PDCP layer specified by the NR protocol. In the embodiment of the present application, the PDCP layer specified by the NR protocol may be simply referred to as NR PDCP layer. The other protocol layers, such as the radio link control (RLC) layer, the media access control (MAC) layer, and the physical layer (PHY), are still used for the above four bearer modes. They are independent in different systems.

上述场景中，每种DRB对应配置包括NR PDCP层的配置信息，在本申请实施例中称为NR PDCP配置，NR PDCP配置与DRB之间一一对应，不同的DRB有相应的NR PDCP配置。示例性的，以DRB为MCG bearer为例，MCG bearer对应一套NR PDCP配置，MCG bearer对应的NR PDCP配置可以包括，但不局限于以下信息：In the above scenario, each DRB corresponding configuration includes the configuration information of the NR PDCP layer, which is referred to as an NR PDCP configuration in the embodiment of the present application, and the NR PDCP configuration has a one-to-one correspondence with the DRB, and different DRBs have corresponding NR PDCP configurations. For example, the DRG is an MCG bearer. The MCG bearer corresponds to a set of NR PDCP configurations. The NR PDCP configuration corresponding to the MCG bearer may include, but is not limited to, the following information:

1、丢弃定时器(discardTimer)的时长设置，用于终端上的NR PDCP层确定几时删除其缓冲器(buffer)中缓存的PDCP服务数据单元(service data unit，SDU)，和该PDCP SDU对应的PDCP协议数据单元(protocol data unit，PDU)；1. The duration setting of the discard timer (discardTimer) is used by the NR PDCP layer on the terminal to determine when to delete the PDCP service data unit (SDU) buffered in the buffer, corresponding to the PDCP SDU. PDCP protocol data unit (PDU);

2、头压缩参数，用于指示数据包在主基站和终端之间传输时使用的头压缩配置(profile)信息；2. The header compression parameter is used to indicate header compression profile information used when the data packet is transmitted between the primary base station and the terminal;

3、重排序定时器(t-reordering)的时长设置，用于指示终端上的NR PDCP层进行重排序操作使用的一个定时器；3. The duration setting of the reordering timer (t-reordering) is used to indicate a timer used by the NR PDCP layer on the terminal to perform a reordering operation;

4、状态报告信息，用于指示终端在RLC确定模式(AM模式)下是否打开NR PDCP状态报告的功能；4. Status report information, which is used to indicate whether the terminal opens the NR PDCP status report in the RLC determination mode (AM mode);

5、PDCP序号(serial number，SN)长度指示；5. PDCP serial number (SN) length indication;

需要说明的是，上述NR PDCP配置在这里只是举例说明，并不对本申请所涉及的NR PDCP配置造成限定，根据实际应用场景的不同，NR PDCP配置可以有其他的配置信息/参数。It should be noted that the foregoing NR PDCP configuration is only an example, and does not limit the NR PDCP configuration involved in the present application. The NR PDCP configuration may have other configuration information/parameters depending on the actual application scenario.

请参阅图3，图3为本申请实施例一种信息处理方法一个实施例信令交互示意图，包括：Referring to FIG. 3, FIG. 3 is a schematic diagram of signaling interaction of an embodiment of an information processing method according to an embodiment of the present disclosure, including:

101、辅基站生成NR PDCP配置。101. The secondary base station generates an NR PDCP configuration.

进而，辅基站向主基站发送NR PDCP配置，以及所述NR PDCP配置对应的DRB的标识信息。Further, the secondary base station sends the NR PDCP configuration to the primary base station, and the identification information of the DRB corresponding to the NR PDCP configuration.

其中，NR PDCP配置与DRB之间存在一一对应的映射关系，NR PDCP配置可以是针对SCG bearer以及SCG split bearer中的任意一种或多种承载方式对应的NR PDCP配置。There is a one-to-one mapping relationship between the NR PDCP configuration and the DRB. The NR PDCP configuration may be an NR PDCP configuration corresponding to any one or more of the SCG bearer and the SCG split bearer.

本实施方式中，辅基站单独生成NR PDCP配置，其中，NR PDCP配置与DRB之间存在一一对应的映射关系。In this embodiment, the secondary base station separately generates an NR PDCP configuration, where there is a one-to-one mapping relationship between the NR PDCP configuration and the DRB.

102、主基站从辅基站接收NR PDCP配置，以及与该NR PDCP配置对应的DRB的标识信息。102. The primary base station receives an NR PDCP configuration from the secondary base station, and identifier information of the DRB corresponding to the NR PDCP configuration.

其中，所述DRB的标识信息可以是DRB标识(DRB identity，DRB ID)，或者其他可以用于标识DRB的信息，具体地，标识信息可以用字符串和/或数字等形式，本申请实施例对此不做特别限定。可以理解，不同的DRB可以通过不同的标识信息来区分。The identifier information of the DRB may be a DRB identity (DRB ID), or other information that may be used to identify the DRB. Specifically, the identifier information may be in the form of a character string and/or a number. This is not specifically limited. It can be understood that different DRBs can be distinguished by different identification information.

在本申请的一些实施例中，辅基站通过与主基站之间的逻辑接口，例如X2接口，可以有多种方式将上述NR PDCP配置，和上述NR PDCP配置对应的DRB的标识信息发送到主基站，为了便于理解，这里以eNB作为主基站(MeNB)，gNB作为辅基站(SgNB)时为例进行示例说明：In some embodiments of the present application, the secondary base station may send the foregoing NR PDCP configuration and the identifier information of the DRB corresponding to the NR PDCP configuration to the primary device in a plurality of manners through a logical interface with the primary base station, for example, an X2 interface. For the sake of understanding, the eNB is used as the primary base station (MeNB) and the gNB is used as the secondary base station (SgNB) as an example.

示例方式1：如图4所示，以EN-DC双连接场景为例，当MeNB确定需要在SgNB上建立承载时(例如：SCG bearer，和/或，SCG split bearer)，会通过MeNB与SgNB之间的X2接口向SgNB发送辅基站增加请求(SgNB addition request)消息，SgNB接收到SgNB addition request消息后，会向MeNB反馈对应的辅基站增加请求确认(SgNB addition request acknowledge)消息，该SgNB addition request acknowledge中包含有SgNB上建立的DRB相关参数，在本申请实施例中，SgNB将NR PDCP配置和DRB的映射关系添加在SgNB addition request acknowledge消息中，即在本申请实施例中，SgNB可以通过SgNB addition request acknowledge消息将生成的NR PDCP配置和DRB的映射关系发送给主基站。Example 1: As shown in Figure 4, taking the EN-DC dual-connection scenario as an example, when the MeNB determines that a bearer needs to be established on the SgNB (for example, SCG bearer, and/or SCG split bearer), it will pass the MeNB and the SgNB. The X2 interface sends a SgNB addition request message to the SgNB, and after receiving the SgNB addition request message, the SgNB feeds back to the MeNB a corresponding SgNB addition request acknowledge message, the SgNB addition message. The request acknowledge includes the DRB-related parameters established on the SgNB. In the embodiment of the present application, the SgNB adds the mapping relationship between the NR PDCP configuration and the DRB in the SgNB addition request acknowledge message, that is, in the embodiment of the present application, the SgNB can pass the SgNB. The SgNB addition request acknowledge message sends the generated NR PDCP configuration and the DRB mapping relationship to the primary base station.

示例方式2：如图5所示，SgNB也可以通过辅基站变更请求确认(SgNB modification request acknowledge)消息将NR PDCP配置，和该NR PDCP配置对应的DRB的标识信息发送给MeNB，即SgNB将NR PDCP配置，和该NR PDCP配置对应的DRB的标识信息包含在SgNB modification request acknowledge发送给MeNB，其中，SgNB modification request acknowledge消息为辅基站接收到辅基站表更请求消息(SgNB modification request)后反馈的消息。Example 2: As shown in FIG. 5, the SgNB may also configure the NR PDCP by using a SgNB modification request acknowledge message, and send the identifier information of the DRB corresponding to the NR PDCP configuration to the MeNB, that is, the SgNB will be the NR. The PDCP configuration, and the identifier information of the DRB corresponding to the NR PDCP configuration is sent to the MeNB in the SgNB modification request acknowledge, where the SgNB modification request acknowledge message is sent after the secondary base station receives the secondary base station table request request message (SgNB modification request). Message.

需要说明的是，除了通过上述SgNB addition request acknowledge消息，或SgNB modification request acknowledge消息将NR PDCP配置和DRB的映射关系发送主基站外，还可以通过辅基站触发的变更咨询(SgNB modification required)消息，或者，通过辅基站修改咨询(SgNB change required)消息，或者辅基站向主基站发送的其他消息，将NR PDCP配置和DRB的标识信息发送给主基站，本申请实施例不做限定。It should be noted that, in addition to transmitting the mapping relationship between the NR PDCP configuration and the DRB by using the SgNB addition request acknowledge message or the SgNB modification request acknowledge message, the SgNB modification required message may be triggered by the secondary base station. Or, the NR PDCP configuration and the ID information of the DRB are sent to the primary base station by using the SgNB change required message or the other information sent by the secondary base station to the primary base station, which is not limited in this embodiment.

应理解，在终端与基站建立DRB时，会先建立终端与核心网设备之间的承载。例如在EN-DC场景下，该承载可以是演进分组***(evolved packet system，EPS)承载，终端会与分组数据网关(packet data network gateway，PDN-GW)建立EPS承载，该EPS承载包括DRB，终端的一条EPS承载可以对应一个DRB，用EPS承载标识(EPS ID)来标识终端的一条EPS承载。也就是说，每个DRB的NR PDCP配置也对应一个EPS承载。但如果辅基站为NR SgNB时，辅基站无法识别EPS承载，因此，辅基站未将NR PDCP配置与EPS承载之间的映射关系发送给主基站。为了让主基站能够获知收到的NR PDCP配置对应哪个承载，本申请实施例提供了一种辅基站向主基站发送EPS ID的方式。It should be understood that when the terminal establishes a DRB with the base station, the bearer between the terminal and the core network device is first established. For example, in an EN-DC scenario, the bearer may be an evolved packet system (EPS) bearer, and the terminal may establish an EPS bearer with a packet data network gateway (PDN-GW), where the EPS bearer includes a DRB. An EPS bearer of the terminal may correspond to one DRB, and an EPS bearer identifier (EPS ID) is used to identify an EPS bearer of the terminal. That is to say, the NR PDCP configuration of each DRB also corresponds to one EPS bearer. However, if the secondary base station is the NR SgNB, the secondary base station cannot identify the EPS bearer. Therefore, the secondary base station does not send the mapping relationship between the NR PDCP configuration and the EPS bearer to the primary base station. In order to enable the primary base station to know which bearer the NR PDCP configuration is received, the embodiment of the present application provides a manner in which the secondary base station sends an EPS ID to the primary base station.

103、主基站向终端发送NR PDCP配置，以及与该NR PDCP配置对应的DRB的标识信息。在本申请实施例中，在主基站获知辅基站发送的NR PDCP配置，与NR PDCP配置对应的DRB的标识信息后，将该NR PDCP配置，该NR PDCP配置对应的DRB的标识信息通知到终端。在主基站与辅基站为不同制式的情况下，主基站直接向终端转发辅基站发送NR PDCP配置与DRB之间的关系，而不会去解析辅基站生成的NR PDCP配置，从而可以有效地解决辅基站下发NR PDCP配置给终端的问题。103. The primary base station sends an NR PDCP configuration to the terminal, and identifier information of the DRB corresponding to the NR PDCP configuration. In the embodiment of the present application, after the primary base station learns the NR PDCP configuration sent by the secondary base station and the identifier information of the DRB corresponding to the NR PDCP configuration, the NR PDCP is configured, and the identifier information of the DRB corresponding to the NR PDCP configuration is notified to the terminal. . When the primary base station and the secondary base station are in different formats, the primary base station directly forwards the relationship between the NR PDCP configuration and the DRB to the secondary base station, and does not analyze the NR PDCP configuration generated by the secondary base station, thereby effectively solving the problem. The secondary base station issues the NR PDCP configuration to the terminal.

104、终端根据NR PDCP配置以及所述DRB的标识信息，对所述DRB进行PDCP层的配置。104. The terminal performs PDCP layer configuration on the DRB according to the NR PDCP configuration and the identifier information of the DRB.

终端接收到NR PDCP配置，以及该NR PDCP配置对应的DRB的标识信息后，利用DRB的标识信息，终端可以确定建立的DRB所对应的NR PDCP配置，从而利用NR PDCP配置对所述DRB进行PDCP层的配置，继而保证该DRB上的数据正常传输。After receiving the NR PDCP configuration and the identifier information of the DRB corresponding to the NR PDCP configuration, the terminal may determine the NR PDCP configuration corresponding to the established DRB by using the identifier information of the DRB, thereby performing PDCP on the DRB by using the NR PDCP configuration. The configuration of the layer, in turn, ensures that the data on the DRB is transmitted normally.

在本申请的一些实施例中，主基站从辅基站接收NR PDCP配置，以及所述NR PDCP配置对应的DRB的标识信息包括：In some embodiments of the present application, the primary base station receives the NR PDCP configuration from the secondary base station, and the identifier information of the DRB corresponding to the NR PDCP configuration includes:

主基站从辅基站接收第一container以及所述DRB的标识信息，第一container只包含NR PDCP配置；The primary base station receives the first container and the identifier information of the DRB from the secondary base station, and the first container only includes the NR PDCP configuration;

其中，第一container与DRB的标识信息一一对应。辅基站通过container的形式生成只包含NR PDCP配置的第一container，并将该第一container发送给主基站。The first container has a one-to-one correspondence with the identification information of the DRB. The secondary base station generates a first container including only the NR PDCP configuration in the form of a container, and sends the first container to the primary base station.

需要说明的是，第一container中只包含辅基站生成的NR PDCP配置可以理解为：辅基站为其生成的NR PDCP配置设置了一个独立的第一container，且该第一container区别与封装其他信息的container。It should be noted that the first container includes only the NR PDCP configuration generated by the secondary base station, which can be understood as: the secondary base station sets an independent first container for the NR PDCP configuration generated by the secondary base station, and the first container distinguishes and encapsulates other information. Container.

应理解，对于LTE-NR DC场景而言，因为主基站与辅基站使用不同的无线接入技术(radio access technologies，RAT)，所以辅基站生成的NR PDCP配置主基站无法识别，如果辅基站将生成NR PDCP配置直接发送给主基站，主基站可能会将辅基站发送的NR PDCP配置作为错误包，从而进行其他处理，例如RRC重连接等处理。而通过本申请实施例，辅基站通过container的形式生成包含有NR PDCP配置的第一container，并将只包含有NR PDCP配置第一container发送给主基站，对于主基站而言，主基站不需要解析该第一container的内容，而是直接透传给终端进行解析，因此，不会认为接收到的第一container为错误包，也不会执行上述其他处理，可以有效地减少不必要的***开销。It should be understood that, for the LTE-NR DC scenario, because the primary base station and the secondary base station use different radio access technologies (RATs), the NR PDCP generated by the secondary base station is not recognized by the primary base station, if the secondary base station The NR PDCP configuration is directly sent to the primary base station, and the primary base station may configure the NR PDCP sent by the secondary base station as an error packet to perform other processing, such as RRC reconnection. With the embodiment of the present application, the secondary base station generates the first container including the NR PDCP configuration in the form of a container, and sends the first container including the NR PDCP configuration to the primary base station. For the primary base station, the primary base station does not need to be configured. The content of the first container is parsed, but is directly transmitted to the terminal for parsing. Therefore, the received first container is not considered to be an error packet, and the other processing is not performed, which can effectively reduce unnecessary system overhead. .

结合上述实施例，主基站向终端发送所述NR PDCP配置以及所述DRB的标识信息包括：In combination with the foregoing embodiment, the sending, by the primary base station, the NR PDCP configuration and the identifier information of the DRB to the terminal includes:

所述主基站向所述终端发送只包含所述NR PDCP配置的第一container以及所述DRB的标识信息。The primary base station sends, to the terminal, identification information including only the first container of the NR PDCP configuration and the DRB.

即主基站在接收到辅基站发送的第一container以及DRB的标识信息后，向终端发送上述第一container以及DRB的标识信息。That is, after receiving the first container and the identification information of the DRB sent by the secondary base station, the primary base station sends the identifier information of the first container and the DRB to the terminal.

当辅基站将生成的NR PDCP配置封装成container的形式发送给主基站，以及发送该第一container对应的DRB的标识信息给主基站后，主基站将该第一container对应的DRB的标识信息发送给终端，并以透传的方式直接向终端转发该第一container，使得终端可以根据该第一container获得到辅基站生成的NR PDCP配置，以及根据接收到的标识信息确定该NR PDCP配置对应的DRB，到这里，辅基站成功的将NR PDCP配置给终端。After the secondary base station encapsulates the generated NR PDCP configuration into a container and sends the identifier information to the primary base station, and sends the identifier information of the DRB corresponding to the first container to the primary base station, the primary base station sends the identifier information of the DRB corresponding to the first container. And the terminal directly forwards the first container to the terminal in a transparent manner, so that the terminal can obtain the NR PDCP configuration generated by the secondary base station according to the first container, and determine, according to the received identification information, the NR PDCP configuration. DRB, here, the secondary base station successfully configures the NR PDCP to the terminal.

在本申请的一些实施例中，主基站从辅基站接收所述NR PDCP配置，以及所述NR PDCP配置对应的DRB的标识信息包括：In some embodiments of the present application, the primary base station receives the NR PDCP configuration from the secondary base station, and the identifier information of the DRB corresponding to the NR PDCP configuration includes:

所述主基站从所述辅基站接收只包含所述NR PDCP配置和所述DRB的标识信息的第一container；NR PDCP配置与DRB承载的标识信息一一对应。由此可见，在本实施例中，辅基站将生成的NR PDCP配置以及DRB的标识信息封装成container的形式发送给主基站，即辅基站将生成的NR PDCP配置连同该NR PDCP配置对应的DRB的标识信息一起封装成container的形式发送给主基站。同理，对于主基站而言，主基站无需解析第一container的内容，不会认为接收到的第一container为错误包，因此不会执行上述其他处理，也可以有效地减少不必要的***开销。The primary base station receives, from the secondary base station, a first container that includes only the NR PDCP configuration and the identifier information of the DRB; the NR PDCP configuration corresponds to the identifier information of the DRB bearer. Therefore, in this embodiment, the secondary base station sends the generated NR PDCP configuration and the ID information of the DRB to the primary base station in the form of a container, that is, the secondary base station generates the NR PDCP configuration along with the DRB corresponding to the NR PDCP configuration. The identification information is encapsulated into a container and sent to the primary base station. Similarly, for the primary base station, the primary base station does not need to parse the content of the first container, and does not consider that the received first container is an error packet, so the above other processing is not performed, and unnecessary system overhead can be effectively reduced. .

结合上述实施例，主基站向终端发送NR PDCP配置以及DRB的标识信息包括：包括：所述主基站向所述终端发送所述第一container。In combination with the foregoing embodiment, the sending, by the primary base station, the NR PDCP configuration and the ID information of the DRB to the terminal includes: the primary base station sending the first container to the terminal.

当辅基站将生成的NR PDCP配置连同NR PDCP配置对应的DRB的标识信息封装成第一container的形式发送给主基站后，主基站以透传的方式直接向终端转发该第一container，使得终端可以根据该第一container获得到辅基站生成的NR PDCP配置，以及该NR PDCP配置对应的DRB的标识信息，从而辅基站成功的将NR PDCP配置给终端。After the secondary base station encapsulates the generated NR PDCP configuration and the identifier information of the DRB corresponding to the NR PDCP configuration into the first container, the primary base station directly forwards the first container to the terminal in a transparent manner, so that the terminal The NR PDCP configuration generated by the secondary base station and the identification information of the DRB corresponding to the NR PDCP configuration may be obtained according to the first container, so that the secondary base station successfully configures the NR PDCP to the terminal.

在本申请实施例中，在主基站与终端之间建立了RRC连接后，主基站会触发RRC连接重配置过程，例如：需要给终端发送空口配置时，此时主基站会向终端发送RRC重配置消息，RRC重配置消息中包含有各种各样具有不同功能的信息元素(information element，信息元素)参数。这里在以实际的例子进行说明。例如，以数据锚点在辅基站的承载(SCG split bearer)为例，假设该SCG split bearer对应DRB ID1，当辅基站收到主基站的该承载建立请求时，辅基站根据主基站请求的DRB ID1，生成对应NR PDCP配置，并只将NR PDCP配置封装在containerl中和对应的DRB ID1标识信息一起发送给主基站。主基站将从辅基站接收到的containerl、以及该containerl对应的DRB ID1的标识信息，以IE参数的形式放在RRC重配置消息中，通过RRC重配置消息将DRB ID1和DRB ID1对应的NR PDCP配置发送给终端。具体的，通过RRC重配置消息将DRB ID和DRB ID对应的NR PDCP配置发送给终端，包括以下两种示例方式：In the embodiment of the present application, after the RRC connection is established between the primary base station and the terminal, the primary base station triggers an RRC connection reconfiguration process. For example, when the air interface configuration needs to be sent to the terminal, the primary base station sends an RRC weight to the terminal. The configuration message, the RRC reconfiguration message contains various information element (information element) parameters with different functions. Here is a practical example. For example, taking the SCG split bearer as the data anchor point, the SCG split bearer is assumed to be the DRB ID1. When the secondary base station receives the bearer setup request from the primary base station, the secondary base station requests the DRB according to the primary base station. ID1, generates a corresponding NR PDCP configuration, and only encapsulates the NR PDCP configuration in the container1 and sends the corresponding DRB ID1 identification information to the primary base station. The primary base station sets the identifier information of the container 1 and the DRB ID1 corresponding to the container1 in the RRC reconfiguration message in the form of an IE parameter, and sets the NR PDCP corresponding to the DRB ID1 and the DRB ID1 through the RRC reconfiguration message. The configuration is sent to the terminal. Specifically, the NR PDCP configuration corresponding to the DRB ID and the DRB ID is sent to the terminal by using an RRC reconfiguration message, including the following two exemplary methods:

示例方式1，NR PDCP配置和DRB的标识信息在RRC重配置消息的形式可以如图6所示：Example 1, the NR PDCP configuration and the ID information of the DRB may be in the form of an RRC reconfiguration message as shown in FIG. 6:

由图6可知，在本申请实施例中，在主基站给终端发送的RRC重配置消息中，包含一个IE，该IE可以是列表的形式，该列表可以是公共分组汇聚协议列表(本申请实施例中称为“CommonPDCPConfigList”)。该列表中的每一项都包含NR PDCP配置对应的container，以及该container对应的DRB的标识信息(DRB ID)，不同的container对应不同的DRB ID，不同的DRB有不同的DRB ID。为了便于理解DRB ID与container之间的映射关系，这里在以实际的例子进行说明。例如，对于MCG bearer而言，PDCP层位于主基站上，一旦主基站配置了MCG bearer，则主基站以container的形式生成该MCG bearer对应的NR PDCP配置，并将该container和对应的DRB ID作为该列表的一项。同理，对MCG split bearer而言，处理方式与MCG bearer完全相同。对于SCG bearer而言，PDCP层位于辅基站上，一旦辅基站配置了SCG bearer，则辅基站以container的形式生成该承载对应的NR PDCP配置，并该container和对应的DRB ID发送给主基站，主基站将从辅基站收到的该container和对应的DRB ID作为列表中的一项。同理，对于SCG split bearer而言，处理方式与SCG bearer完全相同。As shown in FIG. 6 , in the embodiment of the present application, the RRC reconfiguration message sent by the primary base station to the terminal includes an IE, and the IE may be in the form of a list, where the list may be a public packet convergence protocol list. In the example, it is called "CommonPDCPConfigList"). Each item in the list includes a container corresponding to the NR PDCP configuration and a DRB ID (DRB ID) corresponding to the container. Different containers correspond to different DRB IDs, and different DRBs have different DRB IDs. In order to facilitate understanding of the mapping relationship between the DRB ID and the container, a practical example will be described here. For example, for the MCG bearer, the PDCP layer is located on the primary base station. Once the primary base station is configured with the MCG bearer, the primary base station generates the NR PDCP configuration corresponding to the MCG bearer in the form of a container, and uses the container and the corresponding DRB ID as One of the lists. For the same reason, for MCG split bearer, the processing method is exactly the same as MCG bearer. For the SCG bearer, the PDCP layer is located on the secondary base station. Once the secondary base station is configured with the SCG bearer, the secondary base station generates the NR PDCP configuration corresponding to the bearer in the form of a container, and the container and the corresponding DRB ID are sent to the primary base station. The primary base station receives the container and the corresponding DRB ID from the secondary base station as one of the lists. For the same reason, for SCG split bearer, the processing method is exactly the same as SCG bearer.

由此可见，本申请实施例提出了一种具体在RRC重配置消息配置NR PDCP配置以及DRB ID的具体形式。It can be seen that the embodiment of the present application proposes a specific form of configuring the NR PDCP configuration and the DRB ID in the RRC reconfiguration message.

需要说明的是，在本申请实施例中，还存在另一种方式，在主基站给终端发送的RRC重配置消息中，包含一个公共分组汇聚协议列表，该列表中的每一项都包含一个container，该container只包含DRB ID和该DRB ID对应的NR PDCP配置。It should be noted that, in the embodiment of the present application, there is another manner that the RRC reconfiguration message sent by the primary base station to the terminal includes a public packet convergence protocol list, and each item in the list includes one Container, the container contains only the DRB ID and the NR PDCP configuration corresponding to the DRB ID.

示例方式2，NR PDCP配置和DRB的标识信息在RRC重配置消息的形式还可以如图7所示：For example mode 2, the NR PDCP configuration and the ID information of the DRB may also be in the form of an RRC reconfiguration message as shown in FIG. 7:

由图7可知，在本申请实施例中，在主基站给终端发送的RRC重配置消息中，也定义一个“CommonPDCPConfigList”IE，但与图6所示的方式有所区别：在图7所示的CommonPDCPConfigList中，只是针对split bearer，该列表中的每一项可以包含一个NR PDCP配置对应的container以及对应的DRB ID，或者，该列表中的每一项可以包含一个container，该container中只包含NR PDCP配置和对应的DRB ID。As shown in FIG. 7, in the RRC reconfiguration message sent by the primary base station to the terminal, a "CommonPDCPConfigList" IE is also defined in the embodiment of the present application, but differs from the manner shown in FIG. 6: In the CommonPDCPConfigList, only for the split bearer, each item in the list may contain a container corresponding to the NR PDCP configuration and the corresponding DRB ID, or each item in the list may contain a container, and the container only contains NR PDCP configuration and corresponding DRB ID.

而对于MCG bearer与SCG bearer这两种承载而言，MCG bearer与SCG bearer对应的NR PDCP配置的IE位置体不变如图7所示，将MCG bearer对应的container配置在RRC重配置消息中携带的“DBR-ToAddMod”IE中，SCG bearer对应的container配置在RRC重配置消息中携带的“DBR-ToAddModListSCG”IE中，只是将原来的PDCP配置参数替换成一个container，该container中包含MCG bearer，和或SCG bearer承载对应的NR PDCP配置。由此可见，本申请实施例提出了一种具体在RRC重配置消息中配置NR PDCP配置和DRB ID的另一种具体形式。For the two bearers of the MCG bearer and the SCG bearer, the IE location of the NR PDCP configuration corresponding to the MCG bearer and the SCG bearer is unchanged as shown in FIG. 7 , and the container corresponding to the MCG bearer is configured to be carried in the RRC reconfiguration message. In the "DBR-ToAddMod" IE, the corresponding provider of the SCG bearer is configured in the "DBR-ToAddModListSCG" IE carried in the RRC reconfiguration message, except that the original PDCP configuration parameter is replaced with a container, and the container includes the MCG bearer. And the NR PDCP configuration corresponding to the SCG bearer bearer. It can be seen that the embodiment of the present application provides another specific form for configuring the NR PDCP configuration and the DRB ID in the RRC reconfiguration message.

在本申请的实施方式中，终端将以获得的NR PDCP配置和DRB的标识信息，对DRB上的数据进行PDCP层处理，可参阅下述：In the implementation of the present application, the terminal performs PDCP layer processing on the data on the DRB by using the obtained NR PDCP configuration and the ID information of the DRB.

对于上行数据传输，终端对发送的数据进行PDCP层处理包括：对发送的数据进行相应头压缩；对上行传输的用户面数据和控制面数据进行加密/完整性保护；对控制面数据进行完整性保护等处理。对于下行数据传输，终端对接收的数据进行PDCP层处理包括：接收的数据流进行相应的解压缩；对下行传输的用户面数据和控制面数据进行解密/完整性校验；对控制面数据进行完整性校验等处理。需要说明的是，关于NR PDCP层的具体处理过程，由实际DRB的类型对应的NR PDCP配置确定终端执行对应的NR PDCP层处理，具体此处不做限定，将在下一个实施例进行详细叙述。For uplink data transmission, the terminal performs PDCP layer processing on the sent data, including: performing header compression on the transmitted data; performing encryption/integrity protection on the user plane data and control plane data of the uplink transmission; and performing integrity on the control plane data. Protection and other processing. For downlink data transmission, the terminal performs PDCP layer processing on the received data, including: performing corresponding decompression on the received data stream; performing decryption/integrity check on the user plane data and the control plane data of the downlink transmission; and performing control plane data on the control plane data Processing such as integrity check. It should be noted that, in the specific processing procedure of the NR PDCP layer, the NR PDCP configuration corresponding to the type of the actual DRB determines that the terminal performs the corresponding NR PDCP layer processing, which is not limited herein, and will be described in detail in the next embodiment.

需要说明的是，在实际应用中，DRB对应的空口配置信息包括：PDCP配置、RLC配置、MAC配置以及逻辑信道配置等。在本申请的一些实施方式中，辅基站除了将NR PDCP配置单独生成一个第一container之外，还将其他的辅基站的空口配置，例如RLC配置、MAC配置以及逻辑信道配置等单独生成另一个第二container。辅基站除了将第一container和对应DRB ID发送给主基站之外，还可以将第二container和对应DRB ID发送给主基站。主基站将从辅基站收到第一container和DRB ID发送给终端，此外，主基站还将从辅基站收到的第二container和DRB ID发送给终端。It should be noted that, in actual applications, the air interface configuration information corresponding to the DRB includes: a PDCP configuration, an RLC configuration, a MAC configuration, and a logical channel configuration. In some implementations of the present application, the secondary base station separately generates the first container according to the NR PDCP configuration, and separately generates the air interface configuration of the other secondary base station, such as the RLC configuration, the MAC configuration, and the logical channel configuration. The second container. In addition to transmitting the first container and the corresponding DRB ID to the primary base station, the secondary base station may also send the second container and the corresponding DRB ID to the primary base station. The primary base station sends the first container and the DRB ID to the terminal from the secondary base station. In addition, the primary base station sends the second container and the DRB ID received from the secondary base station to the terminal.

本实施例中还存在另一种实现方案。辅基站将NR PDCP配置和对应DRB ID单独生成一个第一container，同时，辅基站还将其他的辅基站的空口配置，例如RLC配置、MAC配置以及逻辑信道配置等，和对应的DRB ID单独生成另一个第二container。辅基站将第一container和第二container发送给主基站。主基站将从辅基站收到的第一container和第二container发送给终端。There is another implementation in this embodiment. The secondary base station separately generates a first container by using the NR PDCP configuration and the corresponding DRB ID, and the secondary base station separately generates air interface configurations of other secondary base stations, such as RLC configuration, MAC configuration, and logical channel configuration, and the corresponding DRB IDs. Another second container. The secondary base station sends the first container and the second container to the primary base station. The primary base station sends the first container and the second container received from the secondary base station to the terminal.

请参阅图8，以SCG split bearer为例，假设该SCG split bearer对应DRB ID1，根据DRB ID1，辅基站将生成DRB ID1对应的NR PDCP配置，并将NR PDCP配置封装在一个container(本申请实施例中称为NR PDCP configuration container)中，同时，根据DRB ID1，辅基站还会生成辅基站的空口配置，该辅基站的空口配置包括：RLC配置、MAC配置以及逻辑信道配置等，这些配置封装在另一个container(在申请实施例中称为辅基站空口配置container)中。辅基站将NR PDCP configuration container、辅基站空口配置container，以及DRB ID1一起发送给主基站。Referring to FIG. 8 , taking the SCG split bearer as an example, the SCG split bearer is assumed to be the DRB ID1. According to the DRB ID1, the secondary base station generates the NR PDCP configuration corresponding to the DRB ID1, and encapsulates the NR PDCP configuration in a container. In the NR PDCP configuration container, the secondary base station also generates an air interface configuration of the secondary base station according to the DRB ID1. The air interface configuration of the secondary base station includes: RLC configuration, MAC configuration, and logical channel configuration. In another container (referred to as a secondary base station air interface configuration container in the application embodiment). The secondary base station sends the NR PDCP configuration container, the secondary base station air interface configuration container, and the DRB ID1 together to the primary base station.

根据DRB ID1，主基站将对应生成主基站的空口配置，该主基站的空口配置包括：主基站的RLC配置、MAC配置以及逻辑信道配置。主基站将DRB ID1、NR PDCP configuration container、辅基站空口配置container以及主基站的空口配置发送给终端。According to the DRB ID1, the primary base station configures an air interface corresponding to the primary base station, and the air interface configuration of the primary base station includes: an RLC configuration, a MAC configuration, and a logical channel configuration of the primary base station. The primary base station sends the DRB ID1, the NR PDCP configuration container, the secondary base station air interface configuration container, and the air interface configuration of the primary base station to the terminal.

本实施例中，还存在另外一种实现方式。根据DRB ID1，辅基站将生成DRB ID1对应的NR PDCP配置，并将NR PDCP配置和DRB ID1一起封装在一个container(本申请实施例中称为NR PDCP configuration container)中，同时，根据DRB ID1，辅基站还会生成辅基站的空口配置，该辅基站的空口配置包括：辅基站的RLC配置、MAC配置以及逻辑信道配置等，这些配置和DRB ID1封装在另一个container(在申请实施例中称为辅基站空口配置container)中。辅基站将NR PDCP configuration container以及辅基站空口配置container一起发送给主基站。In this embodiment, there is another implementation. According to the DRB ID1, the secondary base station will generate the NR PDCP configuration corresponding to the DRB ID1, and encapsulate the NR PDCP configuration and the DRB ID1 together in a container (referred to as an NR PDCP configuration container in the embodiment of the present application), and according to the DRB ID1, The secondary base station also generates an air interface configuration of the secondary base station, where the air interface configuration of the secondary base station includes: RLC configuration, MAC configuration, and logical channel configuration of the secondary base station, and the DRB ID1 is encapsulated in another container (referred to in the application embodiment). Configure the container for the secondary base station air interface. The secondary base station sends the NR PDCP configuration container and the secondary base station air interface configuration container to the primary base station.

根据DRB ID1，主基站将对应生成主基站的空口配置，该主基站的空口配置包括：DRB ID1、主基站的RLC配置、MAC配置以及逻辑信道配置。主基站将NR PDCP configuration container、辅基站空口配置container以及主基站空口配置发送给终端。According to the DRB ID1, the primary base station will configure the air interface corresponding to the primary base station, and the air interface configuration of the primary base station includes: DRB ID1, RLC configuration of the primary base station, MAC configuration, and logical channel configuration. The primary base station sends the NR PDCP configuration container, the secondary base station air interface configuration container, and the primary base station air interface configuration to the terminal.

对于SCG bearer，MCG split bearer和MCG bearer的配置过程与SCG split bearer类似，这里不再赘述。The configuration process of the SCG bearer, the MCG split bearer, and the MCG bearer is similar to that of the SCG split bearer, and is not described here.

为了便于理解本申请实施，这里以EN-DC双连接场景下，利用SCG split bearer进行视频业务数据下行传输为例，对申请实施例进行说明。请参阅图9，图9为本申请实施例一种信息处理方法一个实施例另一流程示意图，包括：In order to facilitate the understanding of the implementation of the present application, the application embodiment will be described by taking an example of the downlink transmission of the video service data by using the SCG split bearer in the EN-DC dual-connection scenario.

本实施方式中，SgNB单独生成SCG split bearer对应的NR PDCP配置，而其中，NR PDCP配置与DRB之间存在一一对应的映射关系，同时，SgNB的空口配置与DRB之间也存在一一对应的映射关系。In this embodiment, the SgNB separately generates the NR PDCP configuration corresponding to the SCG split bearer, and there is a one-to-one mapping relationship between the NR PDCP configuration and the DRB, and there is also a one-to-one correspondence between the air interface configuration of the SgNB and the DRB. Mapping relationship.

可选地，SgNB生成的SgNB的空口配置，SgNB的空口配置包括：RLC配置、MAC配置以及逻辑信道配置等，SgNB将SgNB的空口配置封装在第二container中。可以理解，第二container与第一container是两个独立的container，即，第一container包含SCG split bearer对应的NR PDCP配置；第二container包含辅基站的空口配置。所述第二container可以称为辅基站空口配置container。Optionally, the air interface configuration of the SgNB generated by the SgNB, the air interface configuration of the SgNB includes: an RLC configuration, a MAC configuration, and a logical channel configuration, and the SgNB encapsulates the air interface configuration of the SgNB in the second container. It can be understood that the second container and the first container are two independent containers, that is, the first container includes the NR PDCP configuration corresponding to the SCG split bearer; and the second container includes the air interface configuration of the secondary base station. The second container may be referred to as a secondary base station air interface configuration container.

其中，上述NR PDCP配置可以包括以下信息中的一个或者多个组合：The foregoing NR PDCP configuration may include one or more combinations of the following information:

1、discardTimer的时长设置，用于配置终端上的NR PDCP层确定几时删除其缓冲器中缓存的PDCP SDU，和该PDCP SDU对应的PDCP PDU；The duration of the discardTimer is configured to configure the NR PDCP layer on the terminal to determine when to delete the PDCP SDU buffered in the buffer and the PDCP PDU corresponding to the PDCP SDU.

2、头压缩参数，用于指示数据包在主基站和终端之间传输时使用头压缩的profile配置信息；2. The header compression parameter is used to indicate profile configuration information of the header compression when the data packet is transmitted between the primary base station and the terminal;

3、t-reordering的时长设置，用于指示终端NR PDCP层进行重排序操作中的一个定时器；3. The duration setting of the t-reordering is used to indicate a timer in the reordering operation of the terminal NR PDCP layer;

5、PDCP SN长度指示。5. PDCP SN length indication.

即在建立了SCG split bearer后，需要确定在该SCG split bearer传输数据时的所使用相关配置信息。That is, after the SCG split bearer is established, it is necessary to determine the relevant configuration information used when the SCG split bearer transmits data.

202、SgNB将上述生成的第一container以及DRB ID通过SgNB addition request acknowl edge消息发送到MeNB。202. The SgNB sends the first container and the DRB ID generated by using the SgNB addition request acknowledge edge message to the MeNB.

可选地，所述SgNB addition request acknowledge消息中还包括上述第二container。具体地，如图10所示，SgNB将生成的NR PDCP配置封装成container的形式发送给主基站。此外，SgNB将其他空口配置信息(除NR PDCP配置之外的其他配置)，例如：SgNB的RLC配置、MAC配置以及逻辑信道配置等封装成另一个container，以同样的方式，将上述两个container以及对应的DRB ID一起发送给MeNB。Optionally, the second container is further included in the SgNB addition request acknowledge message. Specifically, as shown in FIG. 10, the SgNB sends the generated NR PDCP configuration into a container and sends it to the primary base station. In addition, the SgNB encapsulates other air interface configuration information (other configurations than the NR PDCP configuration), for example, the RLC configuration of the SgNB, the MAC configuration, and the logical channel configuration into another container, and in the same manner, the above two containers are And the corresponding DRB ID is sent to the MeNB together.

也就是说，在本申请实施例中，SgNB除了将生成的NR PDCP配置和DRB的映射关系通过X2接口消息发送给主基站之外，还可以将SgNB生成的辅站空口配置和DRB的映射关系通过X2接口消息提供给主基站，具体的提供过程相同与SgNB将生成的NR PDCP配置和DRB的映射关系的过程类似，这里不再累赘。That is, in the embodiment of the present application, the SgNB can send the mapping between the generated NR PDCP configuration and the DRB through the X2 interface message to the primary base station, and the mapping between the secondary station air interface configuration and the DRB generated by the SgNB. The X2 interface message is provided to the primary base station, and the specific providing process is similar to the process of mapping the NR PDCP configuration and the DRB that the SgNB will generate, and is not cumbersome here.

203、MeNB将从SgNB接收到的第一container，DRB ID以及MeNB生成的主基站的空口配置，通过Uu接口发送给终端。203. The MeNB receives the first container, the DRB ID, and the air interface configuration of the primary base station generated by the MeNB, and sends the configuration to the terminal through the Uu interface.

可选地，当MeNB接收到上述第二container，MeNB将所述第二container与第一container，DRB ID以及MeNB生成的主基站的空口配置等一同发给终端。具体地，如图11所示，MeNB在从辅基站获取到第一container和第二container，以及这两个container对应的DRB ID后，通过RRC重配置消息发送给终端，其中，RRC重配置消息还包括MeNB自身的主基站空口配置。Optionally, when the MeNB receives the second container, the MeNB sends the second container to the terminal together with the first container, the DRB ID, and the air interface configuration of the primary base station generated by the MeNB. Specifically, as shown in FIG. 11, after acquiring the first container and the second container from the secondary base station, and the DRB ID corresponding to the two containers, the MeNB sends the RRC reconfiguration message to the terminal by using an RRC reconfiguration message, where the RRC reconfiguration message is sent. It also includes the MeNB's own primary base station air interface configuration.

204、终端从MeNB发送的RRC配置信息中获取所需要的配置信息。204. The terminal acquires required configuration information from the RRC configuration information sent by the MeNB.

终端从MeNB接收到RRC重配置消息后，可以从中获取到辅基站的NR PDCP配置、辅基站的空口配置，以及MeNB自身的空口配置。After receiving the RRC reconfiguration message from the MeNB, the terminal may obtain the NR PDCP configuration of the secondary base station, the air interface configuration of the secondary base station, and the air interface configuration of the MeNB itself.

205、终端分别与MeNB和SgNB进行数据传输。205. The terminal performs data transmission with the MeNB and the SgNB, respectively.

具体地，核心网利用SCG split bearer向终端发送下行传输视频业务数据，也就是说核心网需要将终端的视频业务数据发送到SgNB，由SgNB将视频业务数据进行分流，一部分视频业务数据通过MeNB发送给终端，一部分数据通过SgNB直接发送给终端。那么核心网传输视频业务数据之前，MeNB与SgNB需要分别与终端建立对应的split bearer。建立的split bearer分配有对应的DRB ID。由此可得，对终端而言，通过DRB ID可以确定该split bearer对应的L2层(Layer 2)相关的配置信息，由于在步骤204中终端已经获得了MeNB发送的L2层配置，终端可以利用MeNB发送的L2层配置接收核心网下行传输的视频业务数据。Specifically, the core network sends the downlink transmission video service data to the terminal by using the SCG split bearer, that is, the core network needs to send the video service data of the terminal to the SgNB, and the video service data is offloaded by the SgNB, and a part of the video service data is sent by the MeNB. To the terminal, a part of the data is directly sent to the terminal through the SgNB. Before the core network transmits the video service data, the MeNB and the SgNB need to respectively establish a split bearer corresponding to the terminal. The established split bearer is assigned the corresponding DRB ID. Therefore, for the terminal, the configuration information related to the L2 layer (Layer 2) corresponding to the split bearer can be determined by the DRB ID. Since the terminal has obtained the L2 layer configuration sent by the MeNB in step 204, the terminal can utilize the terminal. The L2 layer configuration sent by the MeNB receives the video service data downlinked by the core network.

通过上述描述可知，在本实施例中存在另一种实现方案，即SgNB生成SCG split bearer对应的第一container和第二container，其中，第一container中只包含SCG split bearer对应的NR PDCP配置和对应的DRB ID，第二container中包含SCG split bearer对应的SgNB的空口配置和对应的DRB ID，例如：SgNB的RLC配置、MAC配置以及逻辑信道配置等。SgNB将第一container和第二container通过X2接口发送给主基站。MeNB将从SgNB接收到的两个container，以及MeNB生成的MeNB的空口配置，通过Uu接口发送给终端。As shown in the above description, there is another implementation in this embodiment, that is, the SgNB generates a first container and a second container corresponding to the SCG split bearer, where the first container includes only the NR PDCP configuration corresponding to the SCG split bearer. Corresponding DRB ID, the second container includes the air interface configuration of the SgNB corresponding to the SCG split bearer and the corresponding DRB ID, for example, the RLC configuration, the MAC configuration, and the logical channel configuration of the SgNB. The SgNB sends the first container and the second container to the primary base station through the X2 interface. The MeNB receives the two containers from the SgNB, and the air interface configuration of the MeNB generated by the MeNB is sent to the terminal through the Uu interface.

请参阅图12，图12为本申请实施例一种信息处理方法一个实施例流程示意图，包括：Referring to FIG. 12, FIG. 12 is a schematic flowchart of an embodiment of an information processing method according to an embodiment of the present disclosure, including:

301、基站确定终端支持NR PDCP协议，或者确定终端支持LTE***与NR***的双连接功能。301. The base station determines that the terminal supports the NR PDCP protocol, or determines that the terminal supports the dual connectivity function of the LTE system and the NR system.

其中，在本申请实施例中，基站确定终端支持NR PDCP协议，或者确定终端支持LTE***与NR***的双连接功能，主要存在三种场景，见如下描述：In the embodiment of the present application, the base station determines that the terminal supports the NR PDCP protocol, or determines that the terminal supports the dual connectivity function between the LTE system and the NR system. There are three scenarios, as described below:

第一种场景：当所述终端初始接入所述主基站时，终端会触发附着(Attach)流程，Attach流程包括终端向核心网设备上报能力信息的过程，具体为终端向接入的基站发送能力信息，基站在将终端上报的能力信息转存在至核心网设备中，由此可知，在终端初始接入基站时，基站可以知道终端的能力信息，若终端的能力信息指示终端支持NR PDCP协议或者支持LTE***与NR***的双连接功能，则基站根据接收到的终端的能力信息确定终端支持NR PDCP协议或者支持LTE与NR的双连接功能时，基站向所述终端发送NR PDCP配置。In the first scenario, when the terminal initially accesses the primary base station, the terminal triggers an attach process, and the attach process includes a process in which the terminal reports capability information to the core network device, specifically, the terminal sends the access to the accessed base station. The capability information, the base station forwards the capability information reported by the terminal to the core network device, and thus, when the terminal initially accesses the base station, the base station can know the capability information of the terminal, and if the capability information of the terminal indicates that the terminal supports the NR PDCP protocol. Or supporting the dual connectivity function of the LTE system and the NR system, when the base station determines, according to the capability information of the received terminal, that the terminal supports the NR PDCP protocol or supports the dual connectivity function of LTE and NR, the base station sends the NR PDCP configuration to the terminal.

第二种场景：当接入基站的终端从空闲态(idle)进入连接态(active)时，基站从核心网设备接收终端的能力信息，根据终端的能力信息确定所述终端支持NR PDCP协议或者支持LTE***与NR***的双连接功能。The second scenario is: when the terminal accessing the base station enters an active state from an idle state, the base station receives the capability information of the terminal from the core network device, and determines, according to the capability information of the terminal, that the terminal supports the NR PDCP protocol or Support dual connectivity of LTE system and NR system.

由于终端在接入基站后进入空闲态时，为了减少***负担，基站会清空与终端有关的信息，包括终端的能力信息，而终端在初始接入基站时已经向核心网设备上报终端的能力信息，即核心网设备保存有终端上报的能力信息，因此，当接入基站的终端从空闲态进入激活态时，基站可以通过从核心网设备获取所述终端的能力信息。示例性的，在本申请的一些实施例中，在接入基站的终端从空闲态进入激活态时，核心网设备会通过初始上下文设置请求消息(initial context setup request，S1)向终端发送该终端的相关信息，通过在发送的S1消息携带上指示终端支持NR PDCP协议或者支持LTE***与NR***双连接功能的能力信息，在主基站接收到S1消息后，当通过S1消息携带的能力信息确定终端支持NR PDCP协议或者支持LTE***与NR***的双连接功能后，向终端发送NR PDCP配置。When the terminal enters the idle state after accessing the base station, in order to reduce the system load, the base station clears the information about the terminal, including the capability information of the terminal, and the terminal reports the capability information of the terminal to the core network device when initially accessing the base station. The core network device stores the capability information reported by the terminal. Therefore, when the terminal accessing the base station enters the active state from the idle state, the base station can obtain the capability information of the terminal from the core network device. Exemplarily, in some embodiments of the present application, when the terminal accessing the base station enters the active state from the idle state, the core network device sends the terminal to the terminal by using an initial context setup request (S1). The related information is determined by the capability information carried in the S1 message after the S1 message is received by the S1 message, and the capability information indicating that the terminal supports the NR PDCP protocol or the dual connectivity function of the LTE system and the NR system is carried in the sent S1 message. After the terminal supports the NR PDCP protocol or supports the dual connectivity function of the LTE system and the NR system, the terminal transmits the NR PDCP configuration to the terminal.

第三种场景，终端接入源基站，由前述描述可知，终端在接入源基站时，源基站可以获取终端的能力信息，因此，当所述终端从接入的源基站切换至目标基站时，目标基站可以从所述源基站获取终端的能力信息，目标根据从源基站获取的能力信息确定所述终端支持NR PDCP协议或者支持LTE***与NR***的双连接功能。In a third scenario, the terminal accesses the source base station. According to the foregoing description, when the terminal accesses the source base station, the source base station can acquire the capability information of the terminal, and therefore, when the terminal switches from the accessed source base station to the target base station, The target base station may acquire capability information of the terminal from the source base station, and the target determines, according to the capability information acquired from the source base station, that the terminal supports the NR PDCP protocol or supports the dual connectivity function of the LTE system and the NR system.

应理解，上述三种场景不仅仅可以是指单连接场景下，也适用LTE-NR DC下，在LTE-NR DC场景下，上述基站指的是LTE-NR DC场景下的主基站。It should be understood that the above three scenarios may be used in the LTE-NR DC scenario, and in the LTE-NR DC scenario, the base station refers to the primary base station in the LTE-NR DC scenario.

302、基站向所述终端发送NR PDCP配置。302. The base station sends an NR PDCP configuration to the terminal.

从而，终端在获取到NR PDCP配置之后，可以执行在相应场景下对PDCP层的配置。例如，在双连接场景下，终端采用NR PDCP配置中的参数对接入辅基站进行相关的PDCP配置；在切换场景下，终端采用NR PDCP配置中的参数对接入目标基站进行相关的PDCP配置。具体过程，在此不做赘述。Therefore, after acquiring the NR PDCP configuration, the terminal can perform configuration of the PDCP layer in the corresponding scenario. For example, in a dual-connection scenario, the terminal uses the parameters in the NR PDCP configuration to perform related PDCP configuration on the access secondary base station. In the handover scenario, the terminal uses the parameters in the NR PDCP configuration to perform related PDCP configuration on the access target base station. . The specific process will not be repeated here.

在本申请的一个实施方式中，当所述终端初始接入所述主基站时，所述终端会向所述主基站发送一个指示信息，所述指示信息可以携带在随机接入过程中的消息中，例如通过preamble或者随机接入的消息3(RRC连接建立请求消息或者RRC连接重建立消息)或者随即接入的消息5(RRC连接建立完成消息)向所述主基站发送所述指示信息，所述指示信息用于指示所述终端支持NR PDCP协议或者支持LTE***与NR***的双连接功能，则主基站根据接收到的终端的指示信息确定终端支持NR PDCP协议或者支持LTE与NR的双连接功能时，基站向所述终端发送NR PDCP配置。In an implementation manner of the present application, when the terminal initially accesses the primary base station, the terminal sends an indication information to the primary base station, where the indication information may carry a message in a random access procedure. Sending the indication information to the primary base station, for example, by using a preamble or a random access message 3 (RRC Connection Setup Request message or RRC Connection Re-establishment message) or a random access message 5 (RRC Connection Setup Complete message), The indication information is used to indicate that the terminal supports the NR PDCP protocol or supports the dual connectivity function of the LTE system and the NR system, and the primary base station determines, according to the received indication information of the terminal, that the terminal supports the NR PDCP protocol or supports the pair of LTE and NR. When the function is connected, the base station transmits an NR PDCP configuration to the terminal.

在基站确定终端支持NR PDCP协议或者支持LTE***与NR***的双连接功能后，向终端发送NR PDCP配置。而在LTE***与NR***所构成的双连接场景，基站向终端发送NR PDCP配置的更多细节可以参阅上述描述EN-DC双连接场景下给终端NR PDCP配置的过程，这里不重复赘述。由此可见，本申请实施例提出了基站给终端发送NR PDCP配置的具体场景，提高了方案的可实施性以及多样性。After the base station determines that the terminal supports the NR PDCP protocol or supports the dual connectivity function of the LTE system and the NR system, the NR PDCP configuration is sent to the terminal. In the dual connectivity scenario of the LTE system and the NR system, the details of the NR PDCP configuration sent by the base station to the terminal may be referred to the process of configuring the terminal NR PDCP in the EN-DC dual connectivity scenario, and details are not described herein. It can be seen that the embodiment of the present application proposes a specific scenario in which the base station sends the NR PDCP configuration to the terminal, which improves the implementability and diversity of the solution.

为便于更好的实施本申请上述方法实施例中所描述的方案，下面还提供用于实施上述方案对应的相关装置。In order to facilitate the implementation of the solution described in the foregoing method embodiments of the present application, related devices for implementing the above solutions are also provided below.

请参阅图13，图13为本申请实施例一种基站一个实施例结构示意图，该基站用于作为本申请方法实施例中描述的主基站，包括：接收单元101和发送单元102。Referring to FIG. 13, FIG. 13 is a schematic structural diagram of an embodiment of a base station according to an embodiment of the present application. The base station is used as a primary base station described in the method embodiment of the present application, and includes: a receiving unit 101 and a sending unit 102.

其中，接收单元101，用于从辅基站接收新空口分组数据汇聚协议NR PDCP配置，以及所述NR PDCP配置对应的数据无线承载DRB的标识信息；The receiving unit 101 is configured to receive, by the secondary base station, a new air interface packet data convergence protocol NR PDCP configuration, and identifier information of the data radio bearer DRB corresponding to the NR PDCP configuration;

发送单元102，用于向终端发送所述接收单元101接收的所述NR PDCP配置以及所述DRB的标识信息；The sending unit 102 is configured to send, to the terminal, the NR PDCP configuration received by the receiving unit 101 and the identifier information of the DRB;

其中，所述基站与所述辅基站为不同制式的基站。The base station and the secondary base station are base stations of different standards.

从这里可以看出，在图13所示的基站可以作为主基站，在基站与辅基站为不同制式的情况下，如果沿用现有LTE DC机制，基站会因为无法解析辅基站发送的内容，从而可能导致直接丢弃。为了避免该问题在LTE-NR DC场景出现，则辅基站会通过该基站与辅基站之间的接口直接将NR PDCP配置，以及该NR PDCP配置对应的DRB的标识信息发送给基站，基站可以通过接收单元101接收辅基站发送的NR PDCP配置，以及该NR PDCP配置对应的DRB的标识信息，基站不解析辅基站生成的NR PDCP配置，通过发送单元102直接将收到的NR PDCP配置，和对应的DRB的标识信息转发给终端。It can be seen that the base station shown in FIG. 13 can be used as the primary base station. If the base station and the secondary base station are in different formats, if the existing LTE DC mechanism is used, the base station may not be able to resolve the content sent by the secondary base station, thereby May cause direct discarding. In order to prevent the problem from occurring in the LTE-NR DC scenario, the secondary base station directly transmits the NR PDCP configuration and the identifier information of the DRB corresponding to the NR PDCP configuration to the base station through the interface between the base station and the secondary base station, and the base station can pass the The receiving unit 101 receives the NR PDCP configuration sent by the secondary base station, and the identifier information of the DRB corresponding to the NR PDCP configuration. The base station does not analyze the NR PDCP configuration generated by the secondary base station, and directly configures the received NR PDCP by the sending unit 102, and correspondingly The ID information of the DRB is forwarded to the terminal.

可选地，所述接收单元101用于从辅基站接收NR PDCP配置，以及所述NR PDCP配置对应的DRB的标识信息包括：Optionally, the receiving unit 101 is configured to receive an NR PDCP configuration from the secondary base station, and the identifier information of the DRB corresponding to the NR PDCP configuration includes:

所述接收单元101，用于从所述辅基站接收第一容器container以及所述DRB的标识信息，所述第一container只包含所述NR PDCP配置；The receiving unit 101 is configured to receive, by the secondary base station, a first container, and identifier information of the DRB, where the first container includes only the NR PDCP configuration;

所述发送单元102用于向终端发送所述接收单元101接收的所述NR PDCP配置以及所述DRB的标识信息包括：The transmitting unit 102 is configured to send the NR PDCP configuration that is received by the receiving unit 101 to the terminal, and the identifier information of the DRB includes:

所述发送单元102，用于向所述终端发送所述接收单元101接收的只包含所述NR PDCP配置的第一container以及所述DRB的标识信息；The sending unit 102 is configured to send, to the terminal, identifier information that is received by the receiving unit 101 and includes only the first container of the NR PDCP configuration and the DRB.

其中，所述第一container与所述DRB的标识信息一一对应。The first container has a one-to-one correspondence with the identification information of the DRB.

由此可得，辅基站只将生成的NR PDCP配置封装成container的形式，并发送给图13所示的基站，对于图13所示的基站而言，一方面，基站不需要解析第一container的内容，从而不会认为接收到的第一container为错误包，最后成功通过第一container将NR PDCP配置下发至终端，有效地解决了辅基站怎么下发配置给终端的问题。Therefore, the secondary base station only encapsulates the generated NR PDCP configuration into a container form and sends it to the base station shown in FIG. 13. For the base station shown in FIG. 13, on one hand, the base station does not need to parse the first container. Therefore, the first container is not considered to be an error packet, and finally the NR PDCP configuration is successfully sent to the terminal through the first container, which effectively solves the problem of how the secondary base station sends the configuration to the terminal.

所述接收单元101，用于从所述辅基站接收第一container，所述第一container中包含所述NR PDCP配置和所述DRB的标识信息；The receiving unit 101 is configured to receive a first container from the secondary base station, where the first container includes the NR PDCP configuration and the identifier information of the DRB;

所述发送单元102，用于向所述终端发送所述第一container，所述NR PDCP配置与所述DRB的标识信息一一对应。The sending unit 102 is configured to send the first container to the terminal, where the NR PDCP configuration is in one-to-one correspondence with the identifier information of the DRB.

从这里可以看出，与上述实现不一样的地方在于，第一container除了包含有辅基站的NR PDCP配置之外，还可以只包含该NR PDCP配置对应的DRB的标识信息，也就是说，该第一container中只包含辅基站的NR PDCP配置，以及该NR PDCP配置对应的DRB的标识信息，提高了方案的多样性。It can be seen from the above that the first container has the NR PDCP configuration of the secondary base station, and may include only the identification information of the DRB corresponding to the NR PDCP configuration, that is, the first container. The first container includes only the NR PDCP configuration of the secondary base station and the identification information of the DRB corresponding to the NR PDCP configuration, which improves the diversity of the solution.

可选地，所述接收单元101还用于：Optionally, the receiving unit 101 is further configured to:

从所述辅基站接收第二container，所述第二container包含所述辅基站的空口配置，所述辅基站的空口配置不包含所述NR PDCP配置；Receiving a second container from the secondary base station, where the second container includes an air interface configuration of the secondary base station, and the air interface configuration of the secondary base station does not include the NR PDCP configuration;

所述发送单元102还用于：The sending unit 102 is further configured to:

向所述终端发送所述第二container；Sending the second container to the terminal;

其中，所述第二container与所述DRB的标识信息一一对应。即，图13所示的基站除了将NR PDCP配置配置给终端外，还将辅基站的空口配置发送给终端，保证方案的完整性。The second container has a one-to-one correspondence with the identifier information of the DRB. That is, the base station shown in FIG. 13 transmits the NR PDCP configuration to the terminal, and also sends the air interface configuration of the secondary base station to the terminal to ensure the integrity of the solution.

发送单元202，用于向主基站发送所述NR PDCP配置，以及所述NR PDCP配置对应的数据无线承载DRB的标识信息；The sending unit 202 is configured to send, to the primary base station, the NR PDCP configuration, and the identifier information of the data radio bearer DRB corresponding to the NR PDCP configuration;
