具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述。
除非特别说明，本公开中的“第一”“第二”等描述用来区分不同的对象，并不用来表示大小或时序等含义。
本公开在第一制式网络和第二制式网络组成的多制式网络中，以第一制式网络设备为控制点(或者说，锚点)，联合第二制式网络设备，根据用户的优先级的不同，建立分级的多连接，从而实现差异化的共享网络服务。
图1示出本公开一些实施例的建立分级的多连接的方法的流程示意图。
如图1所示，该实施例的方法包括：步骤110-140。
在步骤110，在第一制式网络和第二制式网络组成的多制式网络中，第一制式网络设备接收用户的终端发送的连接请求。
其中的用户可以是承建运营商的用户或共享运营商的用户。
第一制式网络例如是第四代移动网络或第三代移动网络，第二制式网络例如是第五代移动网络；相应的，第一制式网络设备例如为第四代移动通信的基站(简称4G基站)或第三代移动通信的基站(简称3G基站)，第二制式网络设备例如为第五代移动通信的基站(简称5G基站)，但不限于所举示例。
在步骤120，第一制式网络设备根据用户的优先级，选择与用户的优先级相应级别的第一制式网络的连接策略和第二制式网络的连接策略的组合。
第一制式网络设备可以预先设置不同级别的第一制式网络的连接策略和第二制式网络的连接策略的组合，然后选择与用户的优先级相应级别的第一制式网络的连接策略和第二制式网络的连接策略的组合。用户的优先级越高，选择的组合的性能越好；其中，性能包括覆盖性能、容量性能，或其他性能。
假设：覆盖性能由好到差依次为第一制式网络连接1，2，3，容量性能由大到小依次为第二制式网络连接1，2，3。根据用户签订的共享策略的优先级，选择相应级别的第一制式网络的连接策略和第二制式网络的连接策略的组合。例如，如果用户A的优先级较高，可以选择第一制式网络连接1和第二制式网络连接1的组合，如果用户B的优先级较低，可以选择第一制式网络连接2和第二制式网络连接3的组合。但不限于所举示例。
假设：第一制式网络的覆盖性能优于第二制式网络，第二制式网络的数据传输性能优于第一制式网络，第一制式网络设备可以作为多连接网络的控制点(或者说，锚点)，第一制式网络的连接策略可以部署为第一制式网络的控制面连接，以保证用户可以正常接入网络，在此基础上，针对特定用户，如承建运营商的用户，还可以进一步部署第一制式网络的用户面连接，第二制式网络的连接策略可以部署为第二制式网络的数据面连接(即用户面连接)。第一制式网络的控制面连接策略中的控制面连接的频点低于第二制式网络的用户面连接策略中的用户面连接的频点。从而，通过多连接技术，聚合不同制式移动网络的性能优势为用户服务，用户既能享受到第一制式网络良好的覆盖性能，也能享受到第二制式网络良好的数据传输性能，提高用户的业务体验。
第一制式网络的连接策略包括至少一个第一制式网络的连接配置，每个第一制式 网络的连接配置包括一个第一制式网络连接的频点信息和带宽信息。
第二制式网络的连接策略包括至少一个第二制式网络的连接配置，每个第二制式网络的连接配置包括一个第二制式网络连接的频点信息和带宽信息。
在一些实施例中，用户的终端将所能测量到的频点信息上报给第一制式网络设备，第一制式网络设备从用户的终端所能测量到的频点中，选择与用户的优先级相应级别的第一制式网络的连接策略和第二制式网络的连接策略的组合。从而，结合终端所能测量到的频点和终端所能同时连接多频点的能力，为用户选择有效的连接策略的组合。
例如，如果优先级较高的用户A所能测量到的频点中没有第一制式网络连接1的频点，则第一制式网络连接1和第二制式网络连接1的组合虽然性能级别高，但也不能分配给该用户A，如果用户A所能测量到的频点包括第一制式网络连接2的频点和第二制式网络连接1的频点，可以将第一制式网络连接2和第二制式网络连接1的次优组合分配给该用户A。
在一些实施例中，第一制式网络设备根据用户的优先级和用户所属的运营商，选择与用户的优先级相应级别的和与用户所属的运营商匹配的第一制式网络的连接策略和第二制式网络的连接策略的组合。从而，为不同运营商的用户选择不同的连接策略的组合，为不同运营商的用户提供差异化的共享网络服务。
在一些实施例中，第一制式网络设备从用户的终端所能测量到的频点和终端所能同时连接多频点的能力中，根据用户的优先级和用户所属的运营商，选择与用户的优先级相应级别的和与用户所属的运营商匹配的第一制式网络的连接策略和第二制式网络的连接策略的组合。从而，既能为用户选择有效的连接策略的组合，又能为不同运营商的用户提供差异化的共享网络服务。
根据用户所属的运营商选择连接策略的组合的方案后续会结合图2所示的实施例详细描述。
在步骤130，第一制式网络设备根据第一制式网络的连接策略与用户的终端建立至少一个第一制式网络连接。
如果第一制式网络的连接策略包括一个第一制式网络的连接配置，第一制式网络设备根据一个第一制式网络的连接配置，与用户的终端建立一个第一制式网络连接。
如果第一制式网络的连接策略包括多个第一制式网络的连接配置，第一制式网络设备根据多个第一制式网络的连接配置，分别与用户的终端建立多个第一制式网络连 接。
在步骤140，第一制式网络设备将第二制式网络的连接策略的信息通知第二制式网络设备，使得第二制式网络设备根据第二制式网络的连接策略与用户的终端建立至少一个第二制式网络连接。
如果第二制式网络的连接策略包括一个第二制式网络的连接配置，第二制式网络设备根据一个第二制式网络的连接配置，与用户的终端建立一个第二制式网络连接。
如果第二制式网络的连接策略包括多个第二制式网络的连接配置，第二制式网络设备根据多个第二制式网络的连接配置，分别与用户的终端建立多个第二制式网络连接。
上述实施例，在第一制式网络和第二制式网络组成的多制式网络中，以第一制式网络设备为控制点(或者说，锚点)，联合第二制式网络设备，根据用户的优先级的不同，建立分级的多连接，从而实现差异化的共享网络服务。
图2示出本公开另一些实施例的建立分级的多连接的方法的流程示意图。
如图2所示，该实施例的方法包括以下步骤。
在步骤210，在第一制式网络和第二制式网络组成的多制式网络中，第一制式网络设备接收用户的终端发送的连接请求。
在步骤220，第一制式网络设备根据用户的终端发送的共陆地移动网(Public Land Mobile Network，PLMN)号码，确定用户所属的运营商是承建运营商或者共享运营商。
其中，PLMN号码包括MCC(Mobile Country Code，移动国家码)和MNC(Mobile Network Code，移动网络码)，通过MNC可以确定用户所属的运营商。
第一制式网络设备例如从用户的终端发送的连接请求中获取PLMN号码。
在步骤230，第一制式网络设备根据用户的优先级和用户所属的运营商，选择与用户的优先级相应级别的和与用户所属的运营商匹配的第一制式网络的连接策略和第二制式网络的连接策略的组合。
230a：当用户属于承建运营商时，所选择的第一制式网络的连接策略包括第一制式网络的控制面连接策略和用户面连接策略，选择的第二制式网络的连接策略包括第二制式网络的用户面连接策略。
230b：当用户属于共享运营商时，所选择的第一制式网络的连接策略包括第一制式网络的控制面连接策略，选择的第二制式网络的连接策略包括第二制式网络的用户面连接策略。
在步骤240，当用户属于承建运营商时，第二制式网络设备根据第一制式网络设备通知的第二制式网络的用户面连接策略，与用户的终端建立第二制式网络的至少一个用户面连接(步骤240a)，第一制式网络设备根据第一制式网络的控制面连接策略和用户面连接策略，与用户的终端建立第一制式网络的至少一个控制面连接和至少一个用户面连接，并将第二制式网络的至少一个用户面连接向第一制式网络的至少一个用户面连接分流用户面数据的分流开关打开(步骤240b)，使得用户的用户面数据能够在第一制式网络的至少一个用户面连接和第二制式网络的至少一个用户面连接中传输。
在步骤250，当用户属于共享运营商时，第二制式网络设备根据第一制式网络设备通知的第二制式网络的用户面连接策略，与用户的终端建立第二制式网络的至少一个用户面连接(步骤250a)，第一制式网络设备根据第一制式网络的控制面连接策略，与用户的终端建立第一制式网络的至少一个控制面连接，并将第二制式网络向第一制式网络分流用户面数据的分流开关关闭(步骤250b)，使得用户的用户面数据能够在第二制式网络的至少一个用户面连接中传输。
从而，为不同运营商的用户选择不同的连接策略的组合，为不同运营商的用户提供差异化的共享网络服务。
多连接网络包括核心网和接入网，接入网一般采用控制面和用户面分离的网络架构。以5G移动网络的NSA(Non-Standalone，非独立组网)双连接方案为例，由于4G基站比5G基站的部署频点低，因此，4G基站比5G基站的覆盖范围大，所以，在NSA双连接方案中，由4G基站来负责控制面信令传输，而5G基站和4G基站通过双连接技术共同负责用户面数据传输，从而达到聚合4G和5G移动网络性能的目的。4G基站和5G基站的协议栈例如包括PDCP(Packet Data Convergence Protocol，分组数据汇聚协议)层、RLC(Radio Link Control，无线链路层控制协议)层、MAC(Media Access Control，介质访问控制)层、PHY(Physical，物理)层等。4G基站和5G基站均连接EPC(Evolved Packet Core，演进的分组核心网)。4G基站例如为LTE(Long Term Evolution，长期演进)基站，5G基站例如为NR(New Radio，新空口)基站。
假设覆盖性能由好到差依次为第一制式网络的控制面连接1，2，3，容量性能由大到小依次为第一制式网络的用户面连接1，2，3，容量性能由大到小依次为第二制式网络的用户面连接1，2，3。根据用户签订的共享策略的优先级，选择相应级别的第一制式网络的连接策略和第二制式网络的连接策略的组合。
如图3A所示，如果用户A是共享运营商的用户，并且用户A的优先级较高，第二制式网络(如5G网络)向第一制式网络(如4G网络)分流用户面数据的分流开关关闭，因此，可以选择第一制式网络的控制面连接1和第二制式网络的用户面连接1的组合，控制面信令通过第一制式网络的控制面连接1传输，用户面数据仅通过第二制式网络的用户面连接1传输。控制面信令的传输如虚线箭头所示，用户面数据的传输如实线箭头所示。
如图3B所示，如果用户B是承建运营商的用户，并且用户B的优先级较高，第二制式网络(如5G网络)向第一制式网络(如4G网络)分流用户面数据的分流开关打开，因此，可以选择第一制式网络的控制面连接1和用户面连接1以及第二制式网络的用户面连接1的组合，控制面信令通过第一制式网络的控制面连接1传输，用户面数据通过第一制式网络的用户面连接1和第二制式网络的用户面连接1同时传输。控制面信令的传输如虚线箭头所示，用户面数据的传输如实线箭头所示。
