具体实施方式
本部分将详细描述本申请的具体实施例，本申请之实施例在附图中示出，附图的作用在于用图形补充说明书文字部分的描述，使人能够直观地、形象地理解本申请的每个技术特征和整体技术方案，但其不能理解为对本申请保护范围的限制。
在本申请的描述中，如果有描述到第一、第二、第三只是用于区分技术特征为目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量或者隐含指明所指示的技术特征的先后关系。
本申请的描述中，除非另有明确的限定，设置、安装、连接等词语应做广义理解，所属技术领域技术人员可以结合技术方案的具体内容合理确定上述词语在本申请中的具体含义。
目前5G的标准化正在进行，5G的演进之路较为复杂，目前提出了8种5G网络架构，5G网络的部署难以一蹴而就，需要逐步进行，而目前4G的LTE网络的部署非常广泛，为了避免短期内的高投入以及降低部署风险，运行商大多采用保留LTE网络的5G网络架构，选项4是5G网络架构中的一种，是NE-DC架构，选项4同时引入了5G核心网和5G基站，但5G基站没有直接替代4G基站，在选项4中，5G核心网作为核心网，5G基站作为主站，4G基站作为辅站，5G基站与4G基站之间通过NE-DC功能进行通信，4G基站与5G核心网之间没有NG-U通道，5G核心网的媒体数据无法发送到4G基站，5G核心网的数据只能发送给5G基站，再由5G基站进行数据分流后通过XN-U通道发送给4G基站。按照3GPP的规定，在NE-DC场景下，其中4G的LTE网络必须升级为eLTE网络，即LTE网络需要添加5G的协议层，并且具备与5G核心网进行信令和数据互通的能力，必须引入SDAP(Service Discovery Application Profile，服务发现应用规范)协议层、5G QoS(Quality of Service，服务质量)架构、Session(会话)和QoS Flow(QoS流)，RRC Inactive状态等，eLTE网络必须具备处理NG(无线接入网和5G核心网之间的接口)控制信令和媒体数据的能力，具备处理XN(NG-RAN节点之间的网络接口)的控制信令和媒体数据的能力。但对于选项4，由于4G的LTE网络与5G核心网无NG接口，并不传递控制信令和媒体数据，在此架构下只需要支持eLTE网络的XN媒体数据处理能力即可，不需要支持NG的控制信令和XN的控制信令、媒体数据处理能力，因此将LTE网络升级为eLTE网络，不仅增加了运营商在原有LTE上升级的资源消耗，也增加了设备商实现的复杂度。
基于此，本申请实施例提供一种NE-DC架构的适配方法、运行控制装置、基站设备及存储介质，能够在不升级LTE的情况下，完成NE-DC功能，使得NE-DC架构易于实现。
下面结合附图，对本申请实施例作阐述。
参照图1，图1是本申请实施例提供的一种NE-DC架构的示意图，在该架构中，5G核心网作为核心网，用户终端连接一个5G基站作为主站，用户终端连接一个4G基站作为辅站，4G基站与5G核心网之间没有GN-U通道，4G基站通过XN接口连接5G基站，4G基站中嵌有适配模块，该适配模块能够适配选项4的NE-DC架构中5G基站向4G基站发送的控制信令中的5G概念信息，将该5G信息转换成4G的LTE系统可以识别和运行的信息，可以使得NE-DC功能正常运转。
需要说明的是，该适配模块的开关需要在网管上进行配置，该适配模块不需要在4G基站上增加额外的硬件，只增加单独的软件模块，本申请实施例提供的NE-DC架构易于实现，且该架构不需要将4G基站的LTE网络升级为eLTE网络，减少了4G基站的LTE系统的物理内存资源的占用，尽可能减少了LTE系统中RRC规格的下降。
参照图2，图2是本申请实施例提供的一种NE-DC架构的适配方法，该适配方法应用于4G基站，该4G基站中嵌有适配模块，该适配方法包括但不限于步骤S100、步骤S200和步骤S300。
步骤S100，接收来自5G基站的消息，该消息包括第一信息，第一信息为5G概念信息。
需要说明的是，该消息可以是SN Addition Request(辅站添加请求)消息，也可以是SN Modification Request(辅站修改请求)消息，而且在不同的场景下，第一信息是不同的。
步骤S200，将消息投递给适配模块。
步骤S300，通过适配模块，将消息中的第一信息转换为LTE系统可以识别和运行的第二信息。
在一实施例中，5G基站向4G基站发送包括第一信息的消息，其中第一信息为5G概念的信息，4G基站接收该消息，并将该消息投递给适配模块，适配模块将该消息中的第一信息转换为4G的LTE系统可以识别和运行的第二信息，即4G基站通过适配模块，可以运行和识别来自5G基站的5G概念信息，从而使得NE-DC功能可以运转。
需要说明的是，5G架构中，4G基站需要识别来自5G NR(New Radio，新空口)的5G概念信息，按照3GPP，需要将LTE网络升级为eLTE网络，但本实施例在选项4的NE-DC架构中，通过在4G基站嵌入适配模块，实现NE-DC功能，不需要将LTE网络升级为eLTE网络，使得5G架构中的选项4易于实现，即NE-DC架构更容易实现，且减少了4G基站的LTE系统的物理内存资源的占用，尽可能地减少了LTE系统中RRC规格的下降。
在一实施例中，当第一信息为QoS Flow ID所对应的QoS参数的5QI，如图3所示，本申请实施例提供一种NE-DC架构的适配方法，图3中的步骤S310是图2的步骤S300的细化步骤，且该适配方法还包括步骤S320。
步骤S310，将5QI的取值按照顺序匹配为LTE系统的QCI(QoS Class Identifier，QoS类标识符)的值。
步骤S320，将5QI对应的QoS Flow映射的NR系统的DRB(Data Radio Bearer，数据无线承载)转换为LTE系统的DRB。
需要说明的是，5QI是5G概念信息，用于指向一个5G QoS特性，5QI的取值为0-255；而QCI是LTE网络可以识别和运行的信息，QCI的取值为0-255，适配模块将5QI按顺序转换为取 值相同的QCI。
还需要说明的是，5G的NR系统中，5QI映射有DRB，4G的LTE中QCI也映射有DRB，为了使得NE-DC功能能够正常运行，既要将5QI转换为QCI，也需要为QCI匹配相应的DRB。
在一实施例中，4G基站接收来自5G基站的消息，消息中携带QoS Flow ID所对应的QoS参数的5QI，4G基站将该消息投递给适配模块，以使适配模块将5QI按照顺序匹配为QCI的值，并将5QI对应的QoS Flow映射的NR系统的DRB转换为QCI对应的LTE系统的DRB，从而完成NE-DC功能，4G基站不将LTE网络升级为eLTE网络，通过适配模块，也可以识别5G基站的控制信令。
需要说明的是，5G基站的消息可以是SN Addition Request消息，也可以是SN Modification Request消息。
在一实施例中，若来自5G基站的消息中携带QoS Flow与NR系统的DRB的映射关系，则适配模块将该映射关系中的NR系统的DRB直接转换成LTE系统的DRB，转换后的DRB映射于QCI。
在一实施例中，若来自5G基站的消息中不携带QoS Flow与NR系统的DRB的映射关系，则适配模块从网管中的备用DRB的范围内为LTE系统重新分配DRB。
本领域技术人员应当理解的是，当需要为LTE系统重新分配DRB，在网管上配置时需要使得备用DRB的范围与NR系统的DRB的范围不重叠。
参照图4，图4是选项4下的辅站添加场景的适配流程图，在本申请的一个实施例中，网管配置NE-DC模式为选项4，打开适配模块，5G基站收到用户终端的测量报告，进行4G基站的双连接添加，5G基站向4G基站发送SN Addition Request消息，该4G基站嵌有适配模块，4G基站将SN Addition Request消息投递给适配模块，适配模块将该消息中携带的QoS Flow ID所对应的QoS参数的5QI，按照顺序匹配为LTE系统的QCI；若该消息中携带QoS Flow与NR系统的DRB的映射关系，则适配模块将该映射关系中的NR系统的DRB直接转换成LTE系统的DRB，若该消息不携带QoS Flow与NR系统的DRB的映射关系，则从网管中的备用DRB的范围内为LTE系统重新分配DRB，使得转换后的DRB与转换的QCI形成映射，适配模块将转换后的QCI以及QCI映射到的DRB返回至LTE系统，使得4G基站的LTE系统可以识别和运行来自5G基站的SN Addition Request消息，使得NE-DC功能可以正常运行。
参照图5，图5是选项4下的辅站修改场景的适配流程图，在本申请的另一个实施例中，网管配置NE-DC模式为选项4，打开适配模块，5G基站向4G基站发送SN Modification Request消息，该4G基站嵌有适配模块，4G基站将SN Modification Request消息投递给适配模块，适配模块将该消息中携带的QoS Flow ID所对应的QoS参数的5QI，按照顺序匹配为LTE系统的QCI；若该消息中携带QoS Flow与NR系统的DRB的映射关系，则适配模块将该映射关系中的NR系统的DRB直接转换成LTE系统的DRB，若该消息不携带QoS Flow与NR系统的DRB的映射关系，则从网管中的备用DRB的范围内为LTE系统重新分配DRB，使得转换后的DRB与转换的QCI形成映射，适配模块将转换后的QCI以及QCI映射到的DRB返回至LTE系统，使得4G基站的LTE系统可以识别和运行来自5G基站的SN Modification Request消息，使得NE-DC功能可以正常运行。
参照图6，本申请另一实施例提供一种NE-DC架构的适配方法，该适配方法还包括步骤S400。
步骤S400，根据5G基站的消息和第二信息，通过适配模块，发送相应的回复消息至5G基 站。
在一实施例中，5G基站向4G基站发送消息，4G基站需要返回相应的回复消息至5G基站，4G基站通过适配模块将5G基站的消息中5G概念信息转换为LTE系统可以识别和运行的第二信息，再根据5G基站的消息的内容和转换后的第二信息，通过适配模块产生回复消息，并将回复消息发送给5G基站，4G基站不需要将LTE网络升级为eLTE网络，可以通过适配模块完成NE-DC功能，识别并运行来自5G基站的消息，且可以通过适配模块，向5G基站发送包括5G概念信息的回复消息，从而使得NE-DC功能正常运行，NE-DC架构易于实现。
需要说明的是，回复消息中包括5G概念信息，适配模块产生该回复消息，并将该回复消息返回至4G基站的LTE系统，LTE系统将该回复消息发送至5G基站。
在一实施例中，当5G基站的消息为SN Addition Request消息，第一信息为Desired Activity Notification Level的取值，如图7所示，图7是图6中步骤S300的子步骤流程图，步骤S300包括但不限于步骤D310和D320。
步骤D310，根据Desired Activity Notification Level的取值，保存该SN Addition Request消息中相应的QoS Flow与DRB的映射关系。
步骤D320，检测该映射关系中的DRB的粒度，得到DRB的检测粒度。
如图8所示，图8是图6中步骤S400的子步骤流程图，步骤S400包括但不限于步骤S410和S420。
步骤S410，根据DRB的检测粒度，确认DRB是否处于不活动状态；
步骤S420，在确认DRB处于不活动状态的情况下，根据Desired Activity Notification Level的取值，通过适配模块，发送相应的Activity Notification消息至5G基站。
下面结合附图作详细说明，如图9所示，图9是在选项4用户不活动场景下的适配流程图，在一实施例中，网管配置NE-DC模式为选项4，打开适配模块，在选项4的用户不活动场景下，5G基站向4G基站发送SN Addition Request消息，该消息中的第一信息为Desired Activity Notification Level的取值，4G基站接收SN Addition Request消息，并将该消息投递给适配模块，适配模块可以根据Desired Activity Notification Level的取值，相应地将该SN Addition Request消息中的QoS Flow、PDU Session或者UE的活动状态转换为DRB的活动状态，即根据Desired Activity Notification Level的取值，保存该SN Addition Request消息中相应的QoS Flow与DRB的映射关系，检测该映射关系中的DRB的粒度，得到DRB的检测粒度，并将DRB的检测粒度返回至4G基站的LTE系统；4G基站可以根据DRB的检测粒度，确认DRB处于不活动状态，在确认DRB处于不活动状态的情况下，根据Desired Activity Notification Level的取值，通过适配模块，发送相应的Activity Notification消息至5G基站。
需要说明的是，Desired Activity Notification Level的取值不同，适配模块保存的映射关系也不同，相应地，DRB的检测范围也不同，4G基站给5G基站发送的Activity Notification消息的内容也不同。
还需要说明的是，Activity Notification消息中包括5G概念信息，4G基站使适配模块产生Activity Notification消息，适配模块将Activity Notification消息返回给4G基站的LTE系统，4G基站再将Activity Notification消息发送给5G基站，本领域技术人员应当理解的是，虽然图9中未示出这一过程，但不对本实施例构成限定。
在一实施例中，若Desired Activity Notification Level的取值为QoS Flow，适配模块保存该 SN Addition Request消息中该QoS Flow与DRB的映射关系，检测该映射关系中DRB的粒度，得到DRB的检测粒度，将DRB的检测粒度返回给4G基站的LTE系统，4G基站可以根据DRB的检测粒度，确定该QoS Flow映射的DRB处于不活动状态，且将该DRB的活动状态作为该QoS Flow的活动状态，从而使适配模块产生第一Activity Notification消息，该第一Activity Notification消息携带该QoS Flow，适配模块将第一Activity Notification消息返回给4G基站的LTE系统，LTE系统将第一Activity Notification消息发送给5G基站。
在另一实施例中，若Desired Activity Notification Level的取值为PDU(Protocol Data Unit，协议数据单元)Session，适配模块保存SN Addition Request消息中该PDU Session中的QoS Flow与DRB的映射关系，检测该映射关系中DRB的粒度，得到DRB的检测粒度，将DRB的检测粒度返回给4G基站的LTE系统，4G基站可以根据DRB的检测粒度，确定该PDU Session中的QoS Flow映射的DRB处于不活动状态，且将该DRB的活动状态作为该PDU Session的活动状态，从而使适配模块产生第二Activity Notification消息，该第二Activity Notification消息携带该PDU Session并标明该PDU Session处于不活动状态，适配模块将第二Activity Notification消息返回给4G基站的LTE系统，LTE系统将第二Activity Notification消息发送给5G基站。
在另一实施例中，若Desired Activity Notification Level的取值为UE(User Equipment，用户设备)，适配模块保存该SN Addition Request消息中该UE的所有PDU Session中的QoS Flow与DRB的映射关系，检测该映射关系中DRB的粒度，得到DRB的检测粒度，将DRB的检测粒度返回给4G基站的LTE系统，4G基站可以根据DRB的检测粒度，确定该UE的所有PDU Session中的QoS Flow映射的DRB处于不活动状态，且将该DRB的活动状态作为该UE的活动状态，从而使适配模块产生第三Activity Notification消息，该第三Activity Notification消息标明该UE处于不活动状态，适配模块将第三Activity Notification消息返回给4G基站的LTE系统，LTE系统将第三Activity Notification消息发送给5G基站。
参照图10，当来自5G基站的消息为SN Modification Request消息，第一信息为Lower Layer presence status change(下层状态存在改变)字段，本申请另一实施例提供一种NE-DC架构的适配方法，图10是图2中步骤S300的子步骤流程图，步骤S300包括但不限于步骤T310和步骤T320。
步骤T310，通过适配模块确认SN Modification Request消息中携带Lower Layer presence status change字段。
步骤T320，若Lower Layer presence status change字段的取值为release lower layers(释放下层)，则使适配模块输出第一指令，第一指令用于释放RLC(Radio Link Control，无线链路控制)和MAC(Media Access Control，媒体访问控制)实例；若Lower Layer presence status change字段的取值为release lower layers(暂停下层)，则使适配模块输出第二指令，第二指令用于挂起RLC和MAC实例。
下面结合附图作详细说明，如图11所示，图11是在选项4的RRC Inactive状态的场景中的适配流程图，在本申请的一个实施例中，当5G基站按照策略，使用户终端处于RRC Inactive状态，则通过SN Modification Request中的Lower Layer presence status change告知4G基站，即5G基站向4G基站发送SN Modification Request消息，该SN Modification Request消息携带Lower Layer presence status change字段，4G基站接收该SN Modification Request消息，并将该消息投递给适配模块，适配模块确定该SN Modification Request消息中携带Lower Layer presence status  change字段，若Lower Layer presence status change的取值为release lower layers，则适配模块输出第一指令，并将第一指令返回至4G基站的LTE系统，4G基站可以根据第一指令，释放RLC和MAC实例，若Lower Layer presence status change的取值为suspend lower layers，则适配模块输出第二指令，并将第二指令返回至4G基站的LTE系统，4G基站可以根据第二指令，挂起RLC和MAC实例。
参照图12，本申请实施例还提供一种运行控制装置1200，包括至少一个控制处理器1210和用于与至少一个控制处理器1210通信连接的存储器1220；存储器1220存储有可被至少一个控制处理器1210执行的指令，指令被至少一个控制处理器1210执行，以使至少一个控制处理器1210能够执行如以上实施例所述的NE-DC架构的适配方法，该运行控制装置1200可以实现本申请实施例提供的NE-DC架构的适配方法，4G基站嵌有适配模块，在选项4下，4G基站接收来自5G基站的消息，该消息中包括5G概念信息，则4G基站将该消息投递给适配模块，并通过适配模块，将该消息中的5G概念信息转换为4G的LTE网络可以识别和运行的信息，从而在不将LTE网络升级为eLTE网络的情况下，与5G基站建立NE-DC架构，完成NE-DC功能，不将LTE升级为eLTE,仅增加一个适配模块，减少了LTE系统的物理内存资源的占用，尽可能减少LTE系统中RRC规格的下降，也使NE-DC架构更容易实现。
本申请实施例还提供一种基站设备，包括如上述实施例所述的运行控制装置，该基站设备可以实现本申请实施例提供的NE-DC架构的适配方法，4G基站嵌有适配模块，在选项4下，4G基站接收来自5G基站的消息，该消息中包括5G概念信息，则4G基站将该消息投递给适配模块，并通过适配模块，将该消息中的5G概念信息转换为4G的LTE网络可以识别和运行的信息，从而在不将LTE网络升级为eLTE网络的情况下，与5G基站建立NE-DC架构，完成NE-DC功能，不将LTE升级为eLTE,仅增加一个适配模块，减少了LTE系统的物理内存资源的占用，尽可能减少LTE系统中RRC规格的下降，也使NE-DC架构更容易实现。
