本申请基于申请号为201810829112.6、申请日为2018年07月25日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本公开涉及但不限于移动通信领域，尤其涉及一种信息指示方法、信息指示设备、网元设备、终端及计算机存储介质。
背景技术
当前，全球能源和环境问题严重，网络运营成本居高不下全球能源日益紧张。全球标准组织、运营商、设备商都已行动起来，全面展开节能减排活动。现网运营设备电能消耗主体是网络架构中的各个网元设备(比如基站)，这些网元设备成为节能减排的重点对象，大量的节能减排技术应用到网元设备(比如基站)中。
网元设备为基站时，基站能耗的主要器件是功率放大器(PA，Power Amplier)。每一个基站可以根据业务量的变化适时启动符号级别的PA关断功能，即在没有业务的符号时段内关闭基站中的多个PA，以降低基站的能耗，从而达到节能的目的。
相关技术中，用户设备(UE)是随机接入基站。即使进行业务的UE很少，但由于UE接入基站的随机性，无法将UE集中分配到存在覆盖区的多个基站予以接入，而是随机分配给所有能接入UE的基站，使得所有能接入UE的基站都处于运行状态而减少了符号级别PA关断的概率，因此，使得基站大量耗能。然而，相关技术中，对此并未存在有效的解决方案。

具体实施方式
以下结合附图及实施例，对本公开进行进一步详细说明。应当理解，此处所提供的实施例仅用以解释本公开，并不用于限定本公开。另外，以下所提供的实施例是用于实施本公开的部分实施例，而非提供实施本公开的全部实施例，在不冲突的情况下，本公开实施例记载的技术方案可以任意组合的方式实施。
需要说明的是，在本公开实施例中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的方法或者装置不仅包括所明确记载的要素，而且还包括没有明确列出的其他要素，或者是还包括为实施方法或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的方法或者装置中还存在另外的相关要素(例如方法中的步骤或者装置中的单元，例如的单元可以是部分电路、部分处理器、部分程序或软件等等)。
例如，本公开实施例提供的信息指示方法包含了一系列的步骤，但是本公开实施例提供的该信息指示方法不限于所记载的步骤，同样地，本公开实施例提供的网元设备和终端包括了一系列单元，但是本公开实施例提供的网元设备和终端不限于包括所明确记载的单元，还可以包括为获取相关信息、或基于信息进行处理时所需要设置的单元。
需要说明的是，本公开实施例所涉及的术语“第一\第二”仅仅是区别类似的对象，不代表针对对象的特定排序，可以理解地，“第一\第二”在允许的情况下可以互换特定的顺序或先后次序。应该理解“第一\第二”区分的对 象在适当情况下可以互换，以使这里描述的本公开的实施例能够以除了在这里图示或描述的那些以外的顺序实施。
本公开的信息指示方法的一个应用场景如图1所示，包括：基站101-102，基站101的小区覆盖范围内有三个终端11-13，基站102的小区覆盖范围内有五个终端21-25。终端可以如图1所示为手机终端，也可以为各种物联网终端等。网元设备网元设备(如基站)，其能耗的主要器件为PA，在没有业务的符号时段内可以启动符号级别的PA关断功能，关闭基站中的多个PA可以降低基站的能耗，从而达到节能的目的，从而降低网络运营成本高导致的资源紧张问题。具体地，空口资源分为频域和时域两个维度，满足下行业务信道符号发送时刻频域所有子载波都空闲时可以启动符号级别PA关断，达到节能目的，也不会对业务产生影响。该符号级别PA关断指：在每一个正交频分复用(OFDM，Orthogonal Frequency Division Multiplexing)符号发送时刻所有子载波上都没有信号，或者每一个OFDM符号发送时刻没有数据发送的情况下关闭基站中的多个PA。
符号级别PA关断的概率与业务分布有关，需要满足时域(业务信道符号发送时刻)所有频域资源空闲才能启动。相关技术中，UE是随机接入基站，即使进行业务的UE很少，但由于其随机性，无法分配到重叠覆盖区的多个基站，而是随机分配给所有能接入UE的基站，使得所有能接入UE的基站都处于运行状态而减少了符号级别PA关断的概率，因此，使得基站大量耗能。采用本公开实施例，网元设备发送携带节能接入优先级的广播消息给终端，指示终端根据所述节能接入优先级集中接入节能簇小区，由于加入了节能相关优先级的限制，可以控制UE的集中接入，即将少量UE集中到部分基站(如节能簇小区的基站)，仅占用节能簇小区的基站资源，也就是说，非节能簇小区的基站资源如符号级别PA可以关断，提高了该符号级别PA关断的概率。由于提高了符号级别PA关断的概率，避免了基站耗能，因此，达到了节能的效果。

采用本公开实施例，区别于相关技术是UE随机接入小区，而是通过广播消息指示节能接入优先级信息，实现了在不增加硬件成本的基础上根据小区负荷控制UE接入，在保证业务质量基础上，尽量保证UE集中接入节能簇小区，提高了符号级别PA关断的概率，达到节能的目的，也不会对业务产生影响。
