技术领域
本公开涉及通信技术领域，特别涉及一种基站的共享模式的控制方法、共享基站以及通信系统。
背景技术
5G工作频段高，基站多，基站贵，功耗高(约4G的3倍左右)。为了低成本、高效率建设5G基站(gNodeB)，多个运营商对5G基站或接入网进行共建共享成为必然。共享基站采用独立载波或共享载波是目前提出的两种运营商共建共享接入网的方案。

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，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本公开及其应用或使用的任何限制。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
发明人发现：不同运营商分别配置独立载波可以支持更大的连接数，但也可能造成更大的基站耗能。
本公开所要解决的一个技术问题是：如何使共享基站在保证终端的服务的同时减少共享基站的耗能，节约资源。
本公开提出一种基站的共享模式的控制方法，下面结合图1～图2进行描述。
图1为本公开基站的共享模式的控制方法一些实施例的流程图。如图1所示，该实施例的方法包括：步骤S102～S106。
在步骤S102中，共享基站获取第一预设时间内第一运营商的独立载波的负载和第二运营商的独立载波的负载。
共享基站可以分别配置第一运营商的独立载波和第二运营商的独立载波，第一运营商的终端连接第一运营商的独立载波，相应的，第二运营商的终端连接第二运营商的独立载波。负载例如包括：通话数量、吞吐量或RRC(无线资源控制)连接数，不限于所举示例。
在步骤S104中，共享基站在第一预设时间内各个独立载波的负载总量低于第一阈值的情况下，将第一运营商的独立载波或第二运营商的独立载波切换为共享载波。
第一阈值可以根据切换后共享载波的最大负载量确定。共享基站可以随机选取第一运营商或第二运营商的独立载波切换为共享载波，或者总是选取第一运营商的独立载波切换为共享载波，或者总是选取第二运营商的独立载波切换为共享载波。
在一些实施例中，共享基站在第一运营商的独立载波的负载大于第二运营商的独立载波的负载的情况下，将第一运营商的独立载波切换为共享载波；共享基站在第一运营商的独立载波的负载小于第二运营商的独立载波的负载的情况下，将第二运营商的独立载波切换为共享载波。即共享基站可以选取负载较高的独立载波切换为共享载波，这样可以减少终端的切换次数，节约信令资源。
在步骤S106中，共享基站将未切换为共享载波的独立载波关闭。
例如，共享基站在将第一运营商的独立载波切换为共享载波的情况下，则将第二运营商的独立载波关闭，在将第二运营商的独立载波切换为共享载波的情况下，则将第一运营商的独立载波关闭。共享基站关闭一部分载波的情况下，减少了载波的发送数量，减少了能耗，节约了资源。
在一些实施例中，共享基站在未切换为共享载波的独立载波与终端连接的情况下，向终端发送第一切换指令，其中，第一切换指令包括共享载波对应的频段；共享基站在终端切换至共享载波的情况下，将未切换为共享载波的独立载波关闭。在关闭独立载波之前，需要将独立载波上连接态终端切换至共享载波。针对处于IDLE(空闲)态的终端，独立载波关闭后IDLE态终端会进行小区重选重新连接至共享基站。如果待关闭的独立载波(即未切换为共享载波的独立载波)上连接的终端数量较少，可以等待预设时间，如果在预设时间内这些终端停止业务，则直接将待关闭的独立载波关闭，否则将待关闭的独立载波上连接(Connected)态终端切换至共享载波，再将待关闭的独立载波关闭。
在一些实施例中，在第一运营商的终端和第二运营商的终端均通过共享载波与共享基站连接的情况下，共享基站根据共享载波连接的各个终端的PLMN(Public Land Mobile Network，公共陆地移动网)标识，将第一运营商的终端的信息发送至第一运营商的核心网，将第二运营商的终端的信息发送至第二运营商的核心网。
上述实施例提出了共享基站可以在独立载波和共享载波不同模式下进行切换。共享基站通过判断第一预设时间内第一运营商的独立载波的负载和第二运营商的独立载波的负载，确定是否将第一运营商的独立载波或第二运营商的独立载波切换为共享载波，并将未切换为共享载波的独立载波关闭。从而共享基站在负载较轻的情况下，可以减少载波的数量，还能够同时利用共享载波为不同的运营商的终端提供服务，在保证终端的服务的同时减少了共享基站的耗能，节约了资源，提高了资源利用率。
下面结合图2描述本公开基站的共享模式的控制方法的另一些实施例。
图2为本公开基站的共享模式的控制方法另一些实施例的流程图。如图2所示，该实施例的方法包括：步骤S202～S206。
在步骤S202中，共享基站获取第二预设时间内第一运营商和第二运营商的共享载波的负载。
共享基站可以配置第一运营商和第二运营商的共享载波，第一运营商的终端和第 二运营商的终端均连接共享载波。该共享载波可以是前述实施例中将第一运营商的独立载波或第二运营商的独立载波切换得到的共享载波。
在步骤S204中，共享基站在第二预设时间内共享载波的负载高于第二阈值的情况下，开启第一独立载波。
第一阈值小于或等于第二阈值。共享基站可以将之前关闭的独立载波开启作为第一独立载波，或者，共享基站可以根据各个运营商对应的频段和第一独立载波对应的频段，确定第一独立载波作为第一运营商或第二运营商的独立载波。例如，第一独立载波对应的频段属于第一运营商支持的频段，则将第一独立载波作为第一运营商的独立载波，同理，第一独立载波对应的频段属于第二运营商支持的频段，则将第一独立载波作为第二运营商的独立载波。
在步骤S206中，共享基站将共享载波切换为第二独立载波。
第二独立载波与第一独立载波分别作为不同运营商的独立载波。除了上述实施例中确定第一独立载波和第二独立载波对应的运营商的方法，在一些实施例中，在共享载波上第一运营商的负载大于第二运营商的负载的情况下，共享基站将第一独立载波作为第二运营商的独立载波，将第二独立载波作为第一运营商的独立载波；在共享载波上第一运营商的负载小于第二运营商的负载的情况下，共享基站将第一独立载波作为第一运营商的独立载波，将第二独立载波作为第二运营商的独立载波。即共享基站可以选取负载较低的运营商作为新开启的第一独立载波对应的运营商，可以减少终端的切换次数，节约信令资源。
在一些实施例中，共享基站在共享载波与第一独立载波对应的运营商的终端连接的情况下，向第一独立载波对应的运营商的终端发送第二切换指令，其中，第二切换指令包括第一独立载波对应的频段；共享基站在第一独立载波对应的运营商的终端切换至第一独立载波的情况下，将共享载波切换为第二独立载波。第一独立载波开启后，可以将原共享载波上与第一独立载波对应的运营商的连接(Connected)态终端切换至第一独立载波。IDLE态终端可以不进行处理。
在一些实施例中，共享基站将第一独立载波连接的终端的信息发送至第一独立载波对应的运营商的核心网，将第二独立载波接的终端的信息发送至第二独立载波对应的运营商的核心网。
上述实施例的方法由于独立载波和共享载波都是在RAN侧配置，因此基站可以通过软件配置的方式，在独立载波与共享载波直接进行切换。考虑到一些区域基站的 负载具有潮汐效应，提出了一种基站共享模式的切换策略，在保障运营商各自业务的前提下，可以有效利用网络资源，有效降低共建共享基站的能耗。
