Description

一种***信息的传输方法和通信装置 技术领域
本申请涉及无线通信领域，尤其涉及一种***信息的传输方法和通信装置。
背景技术
随着移动通信技术的不断发展，第五代(the Fifth-Generation，5G)移动通信技术(又称为新无线(New Radio，NR))已经被提出。实际应用中，5G技术的业务非常多样，比如面向增强型移动宽带(enhanced mobile broadband，eMBB)业务、超可靠低延时通信(ultra-reliability low-latency communication，URLLC)业务以及大规模机器通信(massive machine-type communication，mMTC)业务等。其中，大规模机器通信技术尤其适用于视频监控、供货链跟踪、电子支付等领域，具有很高的实用价值。而针对大规模机器通信技术而言，由于其应用领域及场景的特殊性，通常会要求终端设备支持较低的功耗，这样可降低用户的使用成本，从而提升终端设备的用户体验。因此，在针对大规模机器通信技术的研究过程中，如何降低终端设备的功耗成为一大研究热点。
现有技术中，一方面，网络设备会周期性的发送(主要采用广播的方式)***信息。并且，为了更加匹配当前网络***的运行状态，网络设备也会周期性更新其发送的***信息。而另一方面，针对于已经完成与网络设备的初始接入的终端设备而言，在一些情况下，其需要重新获取网络设备发送的***信息，并根据重新获取到的***信息进一步实现与网络设备的数据传输。例如，当终端设备检测到下行链路质量较差时，其会进行重同步操作。在重同步的过程中，终端设备就需要重新获取网络设备发送的***信息。但是，当网络设备发送的***信息并未发生更新的情况下，终端设备在重同步过程中获取的***信息和其重同步之前获取的***信息是相同的，也就是说，终端设备重复获取了相同的***信息，这样必然会产生一些不必要的功耗，而且也降低了终端设备和网络设备之间的数据传输效率，降低了终端设备的用户体验。因此，在***信息获取的过程中，如何降低终端设备的功耗成为需要解决的问题之一。

结合第一方面，在一种可行的实现方式中，终端设备根据获取到的指示规则确定上述指示信息对应指示的上述至少一个第一***信息块，上述指示规则对应于终端设备。基于不同的指示规则对相同的指示信息进行不同的解读，可使得终端设备能够通过有限的指示信息获取更多指示结果，可减少指示信息的开销。
结合第一方面，在一种可行的实现方式中，终端设备还可获取接入指示信息，并根据上述接入指示信息确定网络设备是否允许其接入。根据接入指示信息确定网络设备是否允许接入，可避免因网络设备不允许接入所造成的无效搜索操作，可节省终端设备的功耗。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信***，例如：例如MTC***、码分多址(code division multiple access，CDMA)***、宽带码分多址(wideband code division multiple access，WCDMA)***、通用分组无线业务(general packet radio service，GPRS)、长期演进(long term evolution，LTE)***、LTE频分双工(frequency division duplex，FDD)***、LTE时分双工(time division duplex，TDD)、通用移动通信***(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信***、第五代(5th generation，5G)***或新无线(new radio， NR)等。
本申请实施例中的终端设备可以指用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile Network，PLMN)中的终端设备等，本申请实施例对此并不限定。
本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是全球移动通讯(global system of mobile communication，GSM)***或码分多址(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple Access，WCDMA)***中的基站(NodeB，NB)，还可以是LTE***中的演进型基站(evolutional nodeB，eNB或eNodeB)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等，本申请实施例并不限定。
请参见图1，图1是本申请实施例提供的一种通信***的结构示意图。由图1可知，该通信***包括网络设备和终端设备。网络设备可通过有线连接、无线连接或者其他连接方式与终端设备建立连接。当然，可以理解到的是，该通信***中包含的网络设备可以是一个或者多个，包含的终端设备也可以是一个或者多个(如图1中的终端设备1到终端设备6)。在如图1所示的通信***中，网络设备会周期性向各个终端设备广播***信息。在本申请实施例中，网络设备广播的***信息可以理解为网络设备通过广播发送的高层信息。例如，上述***信息可包括如下信息：主信息块(master information block，MIB)和***信息块(system information block，SIB)。进一步的，根据包含的具体信息的不同，上述***信息块又可以分为***信息块类型一(system information block type1，SIB1)、***信息块类型二(system information block type2，SIB2)、***信息块类型三(system information block type3，SIB3)等等。为了更加匹配当前网络***的运行状态，网络设备也会周期性更新其发送的***信息。而针对于某一个终端设备而言，在一些情况下，其需要重新获取网络设备发送的***信息，并根据重新获取到的***信息进一步实现与网络设备的数据传输。但是，在网络设备发送的***信息并未发生更新的时候，终端设备仍然会重复获取相同的***信息，这样必然会产生一些不必要的功耗，而且也降低了终端设备和网络设备之间的数据传输效率，降低了终端设备的用户体验。
因此，本申请实施例主要解决的技术问题是：在***信息的传输过程中，如何降低终端设备的功耗，以提升终端设备的适用性和用户体验。
实施例一
请参见图2，图2是本申请实施例提供的一种***信息的传输方法的流程示意图。该传输方法适用于图1所示的通信***。该传输方法适用于终端设备和网络设备已经完成初 始化接入的场景。由图2可知，该方法包括以下步骤：
S10，网络设备确定指示信息。
在一些可行的实施方式中，网络设备可根据其发送的第一***信息的更新情况确定出该第一***信息对应的指示信息。这里，上述指示信息用于指示上述第一***信息是否发生更新。上述第一***信息可包括SIB1和除SIB1以外的第一***信息块集合。上述第一***信息块集合中包括至少一个第一***信息块。例如，上述第一***信息块集合中可包括SIB2、SIB3等多个第一***信息块。这里需要解释的是，上述第一***信息可以理解为是前文叙述的***信息的一个子集，该第一***信息中可不包括前文提及的MIB，这样也可降低指示信息的开销，保证指示信息传输的可靠性。特别对于机器类终端设备而言，基于成本的考虑，晶振成本一般比较低，这样就需要机器类终端设备要实时跟踪网络设备的时间信息，而时间信息一般包含于MIB中，因此机器类终端设备需要实时读取MIB信息。基于此，本申请实施例中的指示信息中可以不指示MIB是否更新，这样可以节省指示信息开销，保证指示信息的传输性能。
在本申请中，SIB1可以理解为终端设备与网络设备之间进行数据传输所需要的必要的***信息。例如，SIB1中可包括随机接入信道(random access channel，RACH)的配置信息或者其他***信息SI(即前文描述的第一***信息块集合)对应的调度信息，其他***信息SI也可以理解为除SIB1之外的其他***信息块。在不同的***中，SIB1的名称可能不同。在本申请实施例中，终端设备在检测网络设备发送的物理广播信道(physical broadcast channel，PBCH)之后，为了与网络设备继续数据传输，其第一个需要检测的由网络设备发送的***信息都称为SIB1。除SIB1之外的其他***信息块可以理解为网络设备广播发送的其他***信息。
还需要说明的是，在本申请实施例中，预定义的可以理解为由协议定义的。信令配置的或者预配置的可以理解为由高层或者物理层信令配置的。高层信令例如可以包括无线资源控制(radio resource control，RRC)信令、媒体接入控制(medium access control，MAC)控制元素(control element，CE)、无线链路控制(radio link control，RLC)信令等。物理层信令例如可以包括下行控制信息(downlink control information，DCI)、通过下行物理层信道传输的信令等，物理下行信道例如可以为物理下行控制信道(physical downlink control channel，PDCCH)或者物理下行共享信道(physical downlink shared channel，PDSCH)等。其中，本申请实施例不限制物理下行控制信道的类型和名称，都统称为PDCCH，物理下行控制信道为用于承载下行控制信息的信道，例如可以是NR-PDCCH以及未来通信协议中新定义的作用与物理下行控制信道相近的其他信道。
具体实现中，根据上述指示信息所指示的对象的不同，本申请实施例提供了多种网络设备确定指示信息的实现方式，下面将分别对这多种实现方式进行具体的描述。
实现方式一：
在本实现方式中，指示信息主要用于指示第一***信息这个对象是否发生更新。即，只要是SIB1或者任何一个第一***信息块发生了更新，则网络设备可确定第一***信息发生了更新。这里，上述指示信息中包括第一指示标识。
在一种可选的实现中，网络设备可根据其***配置信息或者***日志信息等确定上述 第一***信息中包括的SIB1和至少一个第一***信息块是否发生更新。若网络设备确定SIB1或者至少一个第一***信息块中的任意一个第一***信息块发生了更新，则可将第一指示标识设置为第一状态。这里，可以理解到的是，第一指示标识的第一状态用于表征第一***信息块发生了更新，第一指示标识的第二状态的用于表征第一***信息块没有发生更新。第一状态和第二状态仅用于指示取值不同或者实现形式不同的第一指示标识，不具备其他限定作用，后文同理，便不再赘述。例如，假设第一指示标识为一个指示比特。若网络设备确定上述SIB1或者至少一个第一***信息块中的任意一个第一***信息块发生了更新，则可将该指示比特设置为1。若网络设备确定上述SIB1和至少一个第一***信息块中的任意一个第一***信息块都没有更新，则可将该指示比特设置为0。
在另一种可选的实现中，网络设备也可根据其***配置信息或者***日志信息等确定上述第一***信息中包括的SIB1和至少一个第一***信息块是否发生更新。若网络设备确定上述SIB1或者至少一个第一***信息块中的任意一个第一***信息块发生了更新，则可将上述第一指示标识由原来的第一状态修改成第二状态。这里，可以理解到的是，上述第一状态为网络设备上一次根据其***配置信息或者***日志信息等判定第一***信息是否发生更新后确定出的第一指示标识的状态。简而言之，就是本实现方式是通过第一指示标识的状态是否发生更改来指示第一***信息是否发生更新。例如，假设第一指示标识为一个指示比特。若网络设备确定SIB1或者至少一个第一***信息块中的任意一个第一***信息块发生了更新，则可将该指示比特的值由0修改成1。当SIB1或者至少一个第一***信息块中的任意一个第一***信息块再次发生更新时，则网络设备可以将该指示比特的值由1再修改为0。若网络设备确定SIB1或者第一***信息块集合中的任意一个第一***信息块都没有更新，则网络设备可不修改指示比特的值。
通过一个第一指示标识来统一指示第一***信息是否发生更新，可避免在第一***信息未发生更新的情况下终端设备重复获取第一***信息的情况的发生，可降低终端设备的功耗。
实现方式二：
在本实现方式中，指示信息主要用于指示第一***信息中包括的SIB1和/或第一***信息块集合是否发生更新。即，只要是SIB1和/或任何一个第一***信息块发生了更新，则网络设备可确定SIB1和/或第一***信息块集合发生了更新。这里，上述指示信息中包括第一指示标识和第二指示标识，第一指示标识、第二指示标识分别用于指示SIB1、第一***信息块集合是否发生更新，例如第一指示标识用于指示SIB1是否发生更新，第二指示标识用于指示第一***信息块集合是否发生更新；或者，第一指示标识用于指示第一***信息块集合是否发生更新，第二指示标识用于指示SIB1是否发生更新。下面，将以指示信息用于指示SIB1和第一***信息块集合是否发生更新这一场景为例，对网络设备确定指示信息的过程进行简单的描述。
在一种可选的实现中，网络设备可根据其***配置信息或者***日志信息等确定第一***信息中包括的SIB1和至少一个第一***信息块是否发生更新。以第一指示标识、第二指示标识分别指示SIB1、第一***信息块集合是否发生更新为例，若网络设备确定SIB1发生更新，则可将上述第一指示标识设置为第一状态。或者，若网络设备确定至少一个第 一***信息块中的任意一个第一***信息块发生了更新，则可将第二指示标识设置为第一状态。若终端设备确定SIB1和至少一个第一***信息块中的任意一个第一***信息块均未发生更新，则可将第一指示标识和第二指示标识设置为第二状态。例如，假设第一指示标识为指示比特A，第一标识为指示比特B。若网络设备确定SIB1发生了更新，且任意一个第一***信息块均未发生更新，则可将该第一指示比特A设置为1，第二指示比特B设置为0。
在另一种可选的实现中，网络设备也可根据其***配置信息或者***日志信息等确定上述第一***信息中包括的SIB1和至少一个第一***信息块是否发生更新。若网络设备确定SIB1发生更新，则可将第一指示标识由原来的第一状态修改成第二状态。若网络设备确定至少一个第一***信息块中的任意一个第一***信息块发生了更新，则可以将第二指示标识由原来的第一状态修改成第二状态。这里，可以理解到的是，在本实现方式中，第一状态为网络设备上一次根据其***配置信息或者***日志信息等确定SIB1和第一***信息块集合是否发生更新后确定出的第一指示标识和第二指示标识的状态。简而言之，就是通过第一指示标识和第二指示标识的状态是否发生更改来指示SIB1或者第一***信息块是否发生更新。例如，假设第一指示标识为第一指示比特A，第二指示标识为第二指示比特B。若网络设备确定SIB1发生更新，则可将该第一指示比特A的值由0修改成1。若网络设备确定任意一个第一***信息块发生了更新，则可将第二指示比特B的值由0修改成1。若网络设备确定SIB1没有更新，则网络设备不修改第一指示比特A的值。若网络设备确定至少一个第一***信息块中的任意一个第一***信息块都没有更新，则网络设备不修改第二指示比特B的值。
通过一个第一指示标识和第二指示标识更加细化的指示第一***信息中包括的SIB1和第一***信息块集合是否发生更新，可避免在SIB1或第一***信息块集合未发生更新的情况下终端设备重复获取SIB1或第一***信息块集合的情况的发生，可降低终端设备的功耗。
实现方式三：
在本实现方式中，指示信息主要用于指示SIB1是否发生更新，以及，第一***信息块集合中的至少一个第一***信息块是否发生更新。换句话说，就是上述指示信息不仅能够指示SIB1是否发生更新，还能具体指示上述第一信息块集合中哪一个或者哪几个第一***信息块发生了更新。
下面，假设上述第一***信息块集合中包括了SIB2、SIB3、***信息块4(system information block type4，SIB4)这三个第一***信息块。假设上述指示信息中包括第一指示标识和第二指示标识。
在一种可选的实现方式中，第一指示标识可用于指示SIB1是否发生更新，第二指示标识可用于指示SIB2、SIB3和SIB4这三个第一***信息块中任意一个或者多个是否发生了更新。具体实现中，网络设备可根据其***配置信息或者***日志信息分别确定上SIB1、SIB2、SIB3和SIB4是否发生更新。若网络设备确定上述SIB1发生更新，则可将第一指示标识设置为第一状态。若网络设备确定SIB2、SIB3或者SIB4中任意一个或者多个发生更新，则可将第二指示标识设置为第一状态。若终端设备确定SIB1、SIB2、SIB3和SIB4均 未发生更新，则可将上述第一指示标识和第二指示标识设置都设置成第二状态。
在另一种可选的实现方式中，假设指示信息中包括第一指示标识、第二指示标识、第三指示标识和第四指示标识。该第一指示标识可用于指示SIB1是否发生更新，该第二指示标识、第三指示标识和第四指示标识可分别用于指示SIB2、SIB3和SIB4是否发生了更新。具体实现中，若网络设备根据其***配置信息或者***日志信息等确定上述SIB1发生更新，则可将第一指示标识设置为第一状态。若网络设备根据其***配置信息或者***日志信息等确定SIB2、SIB3或者SIB4中任意一个或者多个发生更新，则可将发生更新的SIB2、SIB3或者SIB4所对应的第二指示标识、第三指示标识或者第四指示标识设置为第一状态。若终端设备确定SIB1、SIB2、SIB3和SIB4均为发生更新，则可将上述第一指示标识、第二指示标识、第三指示标识和第四指示标识都设置成第二状态。
在又一种实现方式中，网络设备可通过指示信息中包括的指示标识的状态发生改变来指示某一个***信息块发生了更新。结合本实现方式中的前两种实现方式的内容，在指示信息中包括第一指示标识和第二指示标识的情况下，若网络设备确定上述SIB1发生更新，则可将第一指示标识由原来的第一状态修改成第二状态。若网络设备确定SIB2、SIB3或者SIB4中任意一个或者多个发生更新，则可将第二指示标识由原来的第一状态修改成第二状态。若终端设备确定SIB1、SIB2、SIB3和SIB4均未发生更新，则保持第一指示标识和第二指示标识的状态不变。在指示信息中包括第一指示标识、第二指示标识、第三指示标识和第四指示标识的情况下，若网络设备根据其***配置信息或者***日志信息等确定上述SIB1发生更新，则可将第一指示标识由原来的第一状态修改成第二状态。若网络设备根据其***配置信息或者***日志信息等确定SIB2、SIB3或者SIB4中任意一个或者多个发生更新，则可将发生更新的SIB2、SIB3或者SIB4所对应的第二指示标识、第三指示标识或者第四指示标识由原来的第一状态修改为第二状态。若终端设备确定SIB1、SIB2、SIB3和SIB4均未发生更新，则保持上述第一指示标识、第二指示标识、第三指示标识和第四指示标识的状态。
需要说明的是，在本申请实施例中，不同的第一***信息块对应的第一状态可以不同也可以相同，不同的第一***信息块对应的第二状态可以不同也可以相同。这是因为不同的第一***信息块更新的频率可以不相同。因此，在同一时刻，不同的第一***信息块对应的第一状态和/或第二状态可以不同。此外，在本申请实施例中，不同的指示标识对应的第一状态可以相同也可以不相同，不作具体限定。
在通过指示信息中包含的多个指示标识更为细化的指示SIB1以及第一***信息块中包括的各个第一***信息块是否发生变化，可使得终端设备能够更准确的确定出发生更新的***信息块，从而使得终端设备能够更为有效的避免重复读取***信息块，可进一步降低终端设备的功耗。
实现方式四：
在一种可选的实现方式中，由于SIB1中包含有第一***信息块集合所对应的调度信息，这里，上述调度信息用于终端设备和网络设备传输上述第一***信息块集合中包括的第一***信息块。该调度信息可以包括以下至少一项：传输第一***信息块的时间信息、传输第一***信息块的频率资源、编码信息和调制信息等。其中，传输第一***信息块的 时间信息可以表示为网络设备何时发送第一***信息块。传输第一***信息块的频率资源可以表示为网络设备在什么频段上发送第一***信息块。因此，上述指示信息中还可包括一个用于指示SIB1中包括的第一***信息集合的调度信息是否发生更新的标识(为方便区别，下文将以第五指示标识代替描述)。结合实现方式一、实现方式二和实现方式三所描述的网络设备确定指示信息的过程可知，网络设备还可根据其***配置信息或者***日志信息等确定上述调度信息是否发生更新，并通过上述第五标识的状态来指示调度信息是否发生更新。具体过程可一并参见前文，此处便不再赘述。
例如，网络设备可以通过上述第一指示标识和第二指示标识分别指示SIB1没有更新、第一***信息块集合更新，并且同时利用第五指示标识指示第一***信息块集合的调度信息发生更新。在这种情况下，终端设备可以不重新获取SIB1，而按照新的调度信息获取第一***信息块集合中包括的第一***信息块，在这种情况下，新的调度信息可以是预定义的(例如标准协议规范)或者是预配置的(例如通过高层信令、物理层信令指示)。又或者，网络设备根据***配置等原因更新调度信息，例如网络设备可以基于数据传输效率，避免***消息与其他数据传输消息发生碰撞，更新第一***信息块的调度信息，但此时SIB1以及第一***信息块集合包括的第一***信息块未发生改变，在这种情况下，通过这种实现方式，可以避免终端设备重复解读SIB1以及第一***信息块集合中包括的第一***信息块，从而降低终端设备的功耗。
在指示SIB1和第一***信息块集合是否发生更新基础上，再结合第五指示标识来指示第一***信息块集合的调度信息是否发生更新，可在避免终端设备重复获取SIB1或第一***信息块集合同时避免终端设备重复从SIB1中提取上述调度信息，可进一步降低终端设备的功耗，并提升终端设备获取第一***信息的效率。
实现方式五：
在实际应用中，上述第一***信息块集合中可包括多个第一***信息块，而对于不同类型的终端设备来说，其需要解读的第一***信息块可能不相同。比如，针对第一类型的终端设备来说，其可仅需要解读SIB2和SIB3即可，其他第一***信息块可以不解读，而对于第二类型的终端设备来说，其可仅需要解读SIB4和(system information block type5，SIB5)即可，其他第一***信息块可以不解读。这里需要说明的是，在本申请实施例中，终端设备的类型的划分可以有多种方式。例如，可根据终端设备功能划分。或者，根据终端设备的设备能力划分。或者，根据终端设备支持的业务类型划分。或者，根据终端设备的带宽能力划分。当然，可以理解到的是，终端设备的类型的划分还有其他方式，本申请不作具体限定。例如，在根据终端设备支持的业务类型划分的情况下，支持eMBB业务的终端设备、支持URLLC业务的终端设备、支持mMTC业务的终端设备就可以认为是不同类型的终端设备。又例如，在根据终端设备的带宽能力划分的情况下，可以根据终端设备支持的最大信道带宽来区分不同类型的终端设备。这里，终端设备支持的最大信道带宽就是终端设备的带宽能力，也就是当终端设备进行数据传输时可以使用的最大频率资源。这里，终端设备可以使用的最大频率资源在频域上是连续的。或者，终端设备支持的最大信道带宽就是终端设备在一个载波上同时可以使用的最大频率资源。例如，一个终端设备的带宽能力为5MHz，则说明当该终端设备和网络设备之间进行数据传输(包括下行数据的 接收和/或上行数据的发送)时，最大可以在5MHz的频带内被调度。这里，这个5MHz的频带对应的传输带宽需要除去保护带宽。具体的，在根据终端设备的带宽能力划分不同类型终端设备的情况下，可以将带宽能力小于特定阈值的终端设备看为一类终端设备，而将带宽能力大于该特定阈值的终端设备看为另外一类终端设备，这里的特定阈值可以是预定义的，或者是预配置的。
为了节省指示信息所占用的资源，在某些情况下，网络设备可根据不同的指示规则来使用相同的指示标识去指示不同的第一***信息块是否发生更新。这里，上述指示规则表征了上述指示信息与第一***信息块集合中的一个或者多个第一***信息块之间的对应关系。对于终端设备来说，其可根据该指示规则确定其接收到的指示信息对应指示的是第一***信息块集合中的哪一个或者哪几个第一***信息块。这里，同一个指示标识所指示不同第一***信息块可以是同步更新的，但需要说明的是，更新之后的不同第一***信息块发送的时间位置可以是相同的，也可以是不同的。
例如，假设上述指示信息中包括第一指示标识和第二指示标识，其中第一指示标识用于指示SIB1是否发生更新，第二指示标识对于第一类型终端设备而言，可以用于指示SIB2和/或SIB3是否发生更新，对于第二类型终端设备而言，可以用于指示SIB4和/或SIB5是否发生更新，第二指示标识与不同的第一***信息块之间的对应关系(或者，可以理解为第二指示标识所对应的指示规则)可以是预配置的。
又例如，假设上述指示信息中包括第一指示标识、第二指示标识和第三指示标识。网络设备根据其***配置信息或者***日志信息等确定SIB1发生了更新，SIB2和SIB4发生了更新，SIB3和SIB5没有发生更新，则网络设备可将上述第一指示标识设置成第一状态，用于指示SIB1发生更新，将上述第二指示标识设置成第一状态，用于指示SIB2和/或SIB4发生更新，将上述第三指示标识设置成第二状态，用于指示SIB3和SIB5没有发生更新。这样，即可通过上述第一指示标识、第二指示标识和第三指示标识指示SIB1、SIB2、SIB3、SIB4和SIB5这五个***信息块是否发生更新。需要说明的是，网络设备在确定上述第一指示标识、第二指示标识和第三指示标识所对应的状态时需要遵循第一指示标识、第二指示标识和第三指示标识所对应的预定义的指示规则，该指示规则用于表征上述第一指示标识、第二指示标识和第三指示标识中的第一指示标识是用于指示SIB1是否发生更新。而第二指示标识和第三指示标识对于第一类型终端设备来说可以分别用于指示SIB2和SIB3是否更新。对于第二类型终端设备来说可以分别用于指示SIB4和SIB5是否有更新，这样，后续不同类型的终端设备即可根据上述指示规则对上述第一指示标识、第二指示标识和第三指示标识进行不同的解读。这里，网络设备使用相同的指示标识去指示不同的第一***信息块是否发生更新，可节省通信资源。
需要说明的是，在本申请实施例中，不同的第一***信息块集合满足下述特征：如果第一***信息块集合X和第一***信息块集合Y中包括的第一***信息块中至少有一个第一***信息块不同，则可以认为第一***信息块集合X和第一***信息块Y是不同的，其中，第一***信息块集合X中包括至少一个第一***信息块，第一***信息块集合Y中包括至少一个第一***信息块。
可选的，在使用相同的指示标识去指示不同的第一***信息块是否发生更新的场景下， 网络设备还可以利用通信资源不同的指示标识去指示不同的第一***信息块是否发生更新。这里的通信资源包括承载指示信息的信道所占用的资源，具体的，可以包括以下至少一项：时间资源、频率资源、码分资源、无线网络临时标识(radio network tempory identity，RNTI)、承载指示信息的信道所传输的数据大小。例如，假设上述指示信息中包括第一指示标识和第二指示标识，网络设备在T1时刻利用第一指示标识和第二指示标识分别指示SIB1和第一***信息块集合X是否发生更新，而在T2时刻可利用第一指示标识和第二指示标识分别指示SIB1和第一***信息块集合Y是否发生更新。网络设备在不同时刻发送的第二指示标识的状态可以由不同的第一***信息块集合是否发生更新确定，但都共用第二指示标识来指示。相应地，不同类型的终端设备可以根据预定义准则或者预配置信息确定接收指示信息的时刻。同理，网络设备也可在其他不同的通信资源上使用相同的指示标识去指示不同的第一***信息块是否发生更新的情况，具体过程可参见前文叙述的网络设备在不同的时间资源上使用相同的指示标识去指示不同的第一***信息块是否发生更新的过程，此处便不再赘述。
在一些可行的实现方式中，网络设备在确定上述指示信息之前，还可确定出接入指示信息。该接入指示信息用于指示其是否允许终端设备接入。这里，上述接入指示信息中可包括一个第六指示标识。具体实现中，网络设备可以根据当前的网络状态以及终端设备的位置等信息确定其是否允许终端设备接入。可以理解到的是，在实际应用中，网络设备也可以根据其他信息确定出其是否允许终端设备接入，本申请不作具体限定。若网络设备确定允许终端设备接入，则将上述第六指示标识设置为第一状态。若网络设备确定不允许终端设备接入，则将上述第六指示标识设置为第二状态。
具体实现中，在网络设备确定出上述接入指示信息后，网络设备可发送上述接入指示信息。具体实现中，网络设备可通过解调参考信号(demodulation reference signal，DMRS)发送上述接入指示信息，即不同的接入指示信息对应不同的DMRS。进一步可选的，所述DMRS可以用于物理广播信道PBCH信道的解调，或者可以用于与PBCH满足准共位置(quasi-colocation，QCL)关系的数据信道或控制信道的解调。其中，某天线端口符号上的信道特性可以从另一个天线端口推导出，则认为这两个端口满足QCL。或者说，从一个端口获得的信道估计结果，可以用于另一个端口。这里，接入指示信息的不同指的是包含的第六指示标识的标识状态不同。或者，网络设备还可通过同步信号块(synchronization signal block，SSB)承载的时间信息中的预留比特来发送上述接入指示信息。这里，上述SSB承载的时间信息为物理广播信道(physical broadcast channel，PBCH)在物理层处理时额外增加的与时序相关的时间信息。该时间信息一般占用8个比特，其中低两位比特属于预留比特。或者，网络设备还可通过主***信息块MIB的备用比特(spare bit)来发送上述接入指示信息。在本申请实施例中，备用比特和预留比特等价，可相互替用，本申请实施例不作具体限制。
进一步的，可选的，网络设备可以根据其工作的频率范围来确定接入指示信息的承载方式。如表1-1所示，表1-1是本申请实施例提供的一种承载方式指示表。该表中列举了在不同频率范围下，接入指示信息可以使用的承载的方式。如表1-1所示，若网络设备工作的频率范围为第一种频率范围1(frequency range1，FR1)，则DMRS、SSB承载的时间信 息中的预留比特和MIB的备用比特这三种承载方式均可使用。这里，工作在第一种频率范围1下的网络设备，其工作频率小于3GhHz。若网络设备工作的频率范围为第二种频率范围1，则SSB承载的时间信息中的预留比特和MIB的备用比特这二种承载方式均可使用，但DMRS这种承载方式不可用。这里，工作在第二种频率范围1下的网络设备，其工作频率大于或者等于3GhHz且小于或者等于6GHz。若网络设备工作的频率范围为频率范围2(frequency range2，FR2)，则仅MIB的备用比特这种承载方式可使用，DMRS和SSB承载的时间信息中的预留比特这两种承载方式均不可用。这里，在工作频率范围2下的网络设备，其工作频率大于6GHz。

通过接入指示信息指示终端设备能否接入网络设备，可避免无法接入网络设备所进行的无效搜索操作，可节省终端设备的功耗。
这里，还需要补充说明的是，在实际应用中，网络设备不仅可通过指示信息中包括的某一指示标识的不同状态来指示SIB、第一***信息块集合或者第一***信息块集合中任意第一***信息块是否发生更新，还可使用上述指示信息的具体取值来同时指示SIB、第一***信息块集合或者第一***信息块集合中任意第一***信息块这三种信息中至少两种是否发生更新。例如，请参见表1-2，下面以网络设备通过指示信息的取值来指示SIB1和第一***信息块集合是否更新为例，对网络设备通过指示信息的取值进行指示的过程进行简单的描述。表1-2是本申请实施例提供的一种联合指示表。如表1-2所示，当网络设备确定SIB1已更新并且第一***信息块集合未更新时，可将上述指示信息取值为0。当网络设备确定SIB1已更新并且第一***信息块集合已更新时，可将上述指示信息取值为1。当网络设备确定SIB1未更新并且第一***信息块集合已更新时，可将上述指示信息取值为2。当网络设备确定SIB1未更新并且第一***信息块集合也未更新时，可将上述指示信息取值为3。这里，需要理解的是，上述指示信息的取值可以由上述指示信息中包括的一个或者多个比特位的取值来确定，也可由指示信息中包括的其他数据来确定，本申请不作具体限制。

此外，还需要说明的是，在本申请实施例中，当通过指示标识的状态是否发生修改来指示第一***信息中包括的SIB1是否发生更新时，若第一***信息中包括的SIB1发生更新，则网络设备可以将用于指示SIB1是否更新的指示标识(例如前文的第一指示标识)由原来的第一状态修改成第二状态，也可以由原来的第二状态修改成第一状态，这取决于对应SIB1是否更新的指示标识在SIB1没有发生更新时所处于的状态。同理，对于第一***信息块集合或者第一***信息块集合中包括的第一***信息块而言亦是如此，此处便不作赘述。另外，需要理解到的是，指示标识的第一状态或者第二状态只是用于表示更新之前和更新之后的***信息(在本申请实施例中，发生更新后的***信息与发生更新前的***信息视为不同的***信息)。在实际应用中，在不同的时刻，指示标识的第一状态所对应的取值可以不同也可以相同。通俗的来说，就是在不同的时刻，指示标识可用通过不同的取值来表征第一状态，可能在T1时刻第一状态下的指示标识取值为1，在T2时刻，第一状态下的指示标识取值为3。第二状态亦是如此，此处便不再赘述。例如，假设SIB1或者至少一个其他第一***信息块对应的指示标识为2个比特，该2比特可以表示4种状态，分别用状态0、状态1、状态2、状态3表示。假设在T1时刻，某一指示标识对应的***信息发生更新，并且在T1时刻之前该指示标识对应的状态为状态0(此时，状态0可视为第一状态)，则在T1时刻之后，该指示标识对应的状态可以为状态1(此时，状态1可视为第二状态)。在T2时刻(T2时刻在T1时刻之后)，该指示标识对应的***信息再次发生更新，则在T2时刻之后，该指示标识对应的状态可以为状态3(这里状态3也可视为第二状态)，此时在T2时刻之前该指示标识对应的状态1可被视为第一状态。又例如，假设SIB1或者至少一个其他第一***信息块的指示标识对应1比特信息，该1比特可以表示2种状态，分别用状态0、状态1表示。假设在T1时刻，该指示标识对应的***信息发生更新且在T1时刻之前，该指示标识对应的状态为状态0(此时，状态0视为第一状态)，则在T1时刻之后，该指示标识对应的状态可以为状态1(此时，状态1可视为第二状态)。在T2时刻(T2时刻在T1时刻之后)，该指示标识对应的***信息再发生更新，则在T2时刻之后，该指示标识对应的状态可以为状态0(此时，状态0可视为第二状态)，这样，在T2时刻之前该指示标识对应的状态(即状态1)可以视为第一状态。
S20，网络设备通过PDCCH发送上述指示信息。
在一些可行的实现方式中，网络设备在确定出上述指示信息后，可通过PDCCH作为承载来发送上述指示信息。具体实现中，网络设备在确定出上述指示信息后，可从PDCCH所承载的下行控制信息DCI中确定出一个或者多个预留比特，然后将上述指示信息承载于该一个或者多个预留比特中，即上述调度SIB1的DCI中一个或多个预留比特用于承载指示信息。这里，上述DCI用于调度SIB1。或者，网络设备在确定出上述指示信息后，还可从用于调度寻呼信息的DCI中确定出一个或者多个预留比特，上述调度寻呼信息的DCI通过PDCCH承载，然后将上述指示信息承载于上述一个或者多个预留比特中，即上述调度寻呼信息的DCI中一个或多个预留比特用于承载指示信息。换一句话说，就是上述指示信息所包含的指示标识可以是调度SIB1的DCI中的预留比特或者调度寻呼信息的DCI中的 预留比特。可以理解到的是，实际应用中，网络设备还可通过其他承载来发送上述指示信息，本申请实施例不作具体限制。
在一些可行的实现方式中，网络设备在确定出上述第一***信息发生更新后，还可将更新后的第一***信息发送出。
S30，终端设备检测PDCCH，并获取上述指示信息。
在一些可行的实施方式中，终端设备可实时的或者周期性的检测PDCCH，并从中确定出上述指示信息，终端设备还可以根据网络设备的指示确定检测PDCCH的时刻，并检测PDCCH。具体实现中，终端设备可通过接收SIB1PDCCH得到DCI，然后从该DCI的一个或者多个预留比特中确定出上述指示信息。或者，终端设备还可读取PDCCH以得用于调度寻呼信息的DCI中的一个或者多个预留比特，并基于这一个或者多个预留比特确定出上述指示信息。
S40，若上述指示信息指示第一***信息发生更新，则终端设备接收更新后的第一***信息。
在一些可行的实现方式中，终端设备在接收到上述指示信息后，可根据上述指示信息确定上述第一***信息是否发生更新，并在确定第一***信息发生更新的情况下接收更新后的第一***信息。
在具体实现中，根据上述指示信息所指示的对象的不同，终端设备根据指示信息确定第一***信息的过程也不相同。下面将结合步骤S10中描述的多种确定指示信息的过程对以下几种终端设备根据指示信息确定第一***信息是否发生更新的过程进行具体的描述。
确定过程一：
针对于步骤S10中的实现方式一，在指示信息包括第一指示标识情况下，若终端设备确定该第一指示标识为第一状态，则可确定SIB1和/或至少一个第一***信息块中的任意一个第一***信息块发生了更新。或者，若终端设备确定该第一指示标识由第一状态修改成第二状态，则可确定SIB1和/或至少一个第一***信息块中的任意一个第一***信息块发生了更新。
根据第一指示标识来确定第一***信息是否发生更新，可避免在第一***信息未发生更新的情况下重复获取第一***信息的情况的发生，可降低终端设备的功耗。确定过程二：
针对于步骤S10中的实现方式二，在指示标识包括第一指示标识和第二指示标识的前提下，若终端设备确定该第一指示标识为第一状态或者由第一状态修改成第二状态，则可确定SIB1发生了更新。若终端设备确定该第一指示标识为第二状态或者第一指示标识的状态未修改，则可确定SIB1没有更新。若网络设备确定第二指示标识为第一状态或者由第一状态修改成第二状态，则可确定第一***信息块集合发生了更新。
根据第一指示标识和第二指示标识确定出SIB1和第一***信息块集合是否发生更新，可避免在SIB1或第一***信息块集合未发生更新的情况下重复获取SIB1或第一***信息块集合的情况的发生，可降低终端设备的功耗。
确定过程三：
针对于步骤S10中的实现方式三，终端设备不仅可以根据上述指示信息确定出SIB1是否发生更新。还可根据上述指示信息具体确定出上述第一***信息块集合中的哪一个或 者哪几个第一***信息块发生了更新。
在一种实现中，假设上述指示信息中包括第一指示标识和第二指示标识。上述第一指示标识可用于指示SIB1是否发生更新，上述第二指示标识可用于指示SIB2、SIB3和SIB4这三个第一***信息块中任意一个或者多个是否发生了更新。若终端设备确定上述第一指示标识和第二指示标识均为第一状态，或者，终端设备确定上述第一指示标识和第二指示标识均由第一状态改变至第二状态，则终端设备可确定SIB1发生更新，也可确定SIB2、SIB3或者SIB4中任意一个或者多个发生了更新。若终端设备确定上述第一指示标识和第二指示标识均为第二状态，或者，终端设备确定上述第一指示标识和第二指示标识的状态均未改变，则终端设备可确定SIB1、SIB2、SIB3或者SIB4均为发生更新。
在另一种实现中，假设上述指示信息中包括第一指示标识、第二指示标识、第三指示标识和第四指示标识。上述第一指示标识可用于指示SIB1是否发生更新，上述第二指示标识、第三指示标识和第四指示标识分别用于指示SIB2、SIB3和SIB4是否发生了更新。具体实现中，同理，终端设备可根据上述第一指示标识、第二指示标识、第三指示标识和第四指示标识当前的状态或者状态是否发生变化来分别确定SIB1、SIB2、SIB3或者SIB4是否发生更新。
根据指示信息中包含的多个指示标识更为细化确定SIB1以及第一***信息块中包括的各个第一***信息块是否发生变化，可使得终端设备能够更准确的确定出发生更新的***信息块，从而使得终端设备能够更为有效的避免重复读取***信息块，可进一步降低终端设备的功耗。
确定方式四：
针对于步骤S10中的实现方式四，终端设备在根据指示信息确定第一***信息中的SIB1或者第一***信息块集合终端一个或者多个第一***信息块是否发生更新的同时，还可根据第五指示标识当前的状态或者标识状态是否发生改变来确定第一***信息块集合的调度信息是否发生更新。需要说明的是，一般而言，上述第一***信息集合对应的调度信息(如网络设备传输第一***信息集合中的第一***信息块对应的时间窗信息)是包含在SIB1 PDSCH中的。因此，当上述指示信息指示SIB1发生更新时，可包含两种情况。第一种情况是SIB1中包含的第一***信息块集合的调度信息发生了更新。第二种情况是SIB中除上述调度信息以外的其他信息发生了更新，但上述调度信息未发生更新。因此，为了保证网络设备传输第一***信息块集合中包括的第一***信息块的灵活性的同时降低终端设备检测***信息的功耗，网络设备可在上述指示信息中包括一个第五指示标识来指示上述调度信息是否发生更新。这样可以使得终端设备在确定调度信息更新但第一***信息块和SIB1都未更新的情况下，不用去获取SIB1 PDSCH中承载的信息，而按照之前已经获取到的第一***信息块集合对应的调取信息来确定更新后的第一***信息块，这样既可在保证网络设备传输第一***信息块的灵活性的同时降低终端设备检测***信息的功耗。
这里，在确定第一***信息是否发生更新的同时确定第一***信息块集合的调度信息是否发生更新，可在避免终端设备重复获取SIB1或第一***信息块集合同时避免终端设备重复从SIB1中提取上述调度信息，可进一步降低终端设备的功耗，并提升终端设备获取第一***信息的效率。
确定方式五：
针对于步骤S10中的实现方式五所涉及的内容，由于上述指示信息对于不同类型的终设备指示了不同的第一***信息块的更新情况。所以，终端设备在根据指示信息确定第一***信息是否发生更新之前，需要先确定出其对应的指示规则。具体实现中，上述指示规则可以是预定义的例如标准协议规范的，也可以是终端设备通过RRC信息、MAC信息、物理层信息等载体从网络设备处获取的，本申请不做具体限制。这里需要说明的是，针对于不同类型的终端设备，其可根据不同的指示规则对上述指示信息进行解读。也就是说，所述指示规则用于表征***信息块的类型与指示信息之间的对应关系。
例如，假设上述指示信息中包括第二指示标识和第三指示标识。若终端设备为第一类型终端设备，所述终端设备对应的指示规则为第一指示规则，或者根据网络设备发送的配置信息确定其对应的指示规则为第一指示规则，该第一指示规则可定义第二指示标识和第三指示标识用于指示SIB2和SIB3是否发生更新。若终端设备为第二类型终端设备，所述终端设备对应的指示规则为第二指示规则，或者根据网络设备发送的配置信息确定其对应的指示规则为第二指示规则，该第二指示规则可定义第二指示标识和第三指示标识用于指示SIB4和SIB5是否发生更新。以上仅是一种示例性的说明，针对不同类型的终端设备，指示规则可以不同，但不限定于上述示例。
终端设备在根据其对应的终端类型确定出其对应的指示规则后，或者根据网络设备发送的配置信息确定出其对应的指示规则后，可根据该指示规则确定出上述指示信息所对应指示的一个或者多个第一***信息块。然后，终端设备可根据上述指示信息中包括的指示标识的状态确定出SIB1和上述一个或者多个第一***信息块是否发生更新。例如，假设上述指示信息中可包括第一指示标识、第二指示标识和第三指示标识。终端设备根据其对应的指示规则确定上述第二指示标识和第三指示标识用于指示SIB2和SIB3是否发生更新。终端设备在获取到上述第一指示标识、第二指示标识和第三指示标识后，若终端设备确定上述第一指示标识、第二指示标识和第三指示标识均为第一状态，或者，终端设备确定上述第一指示标识、第二指示标识和第三指示标识均由第一状态改变至第二状态，则终端设备可确定SIB1、SB2、SIB3均发生了更新。若终端设备确定上述第一指示标识、第二指示标识和第三指示标识均为第二状态，或者，终端设备确定上述第一指示标识、第二指示标识和第三指示标识均未改变，则终端设备可确定SIB1、SIB2、SIB3均为发生更新。
根据不同的指示规则对上述指示信息进行解读，可使得终端设备能够准确的确定出其倾向或者重点关注的***信息块是否发生更新，从而使得终端设备能够更为有效的避免重复读取***信息块，可进一步降低终端设备的功耗。
在一些可行的实现方式中，若终端设备确定出上述第一***信息中的SIB1发生更新，则可在第一时刻接收更新后的SIB1。若终端设备确定出上述第一***信息中的至少一个第一***信息块发生更新，则可在第二时刻接收更新后的至少一个第一***信息块。上述第一时刻和第二时刻可以为同一时刻，也可以为不同的时刻，本申请不做具体限制。这里，上述第一时刻或者第二时刻可以是由网络设备直接指示的，也可以是网络设备和终端设备事先约定好的，例如标准协议规定的，本申请实施例中不作具体限制。
另外，针对于前文叙述的网络设备使用指示信息的取值来同时指示SIB、第一***信 息块集合或者第一***信息块集合中任意第一***信息块这三种信息中至少两种是否发生更新的情况，终端设备在获取到上述指示信息后，也可根据指示信息的具体取值来确定SIB、第一***信息块集合或者第一***信息块集合中任意第一***信息块是否发生更新。例如，结合前文上述基于指示信息取值同时进行指示的内容及表1-2的内容，请参见表1-3，表1-3是本申请实施例提供的一种指示信息取值与终端设备行为的关系映射表。如表1-3示出了指示信息的不同取值所指示的SIB1和第一***信息块集合是否更新的结果以及终端设备相应的对***信息处理行为。具体的，当终端设备确定指示信息取值为0，则可确定SIB1已更新并且第一***信息块集合未更新时，则可重新解读SIB1 PDSCH但不解读第一***信息块集合。当终端设备确定指示信息取值为1，则可确定SIB1已更新并且第一***信息块集合也已更新，可重新解读SIB1 PDSCH和第一***信息块集合。当终端设备确定指示信息取值为2时，可确定SIB1未更新并且第一***信息块集合已更新，可不解读SIB1但重新解读第一***信息块。当终端设备确定指示信息取值为3时，可确定SIB1未更新并且第一***信息块集合也未更新时，可不解读SIB1和第一***信息块均。这里，指示信息承载在PDCCH中。SIB1 PDSCH表示承载SIB1的物理下行共享信道PDSCH。不重新解读SIB1和第一***信息块集合，可以表示不重新接收与SIB1相关联的信道以及与第一***信息块集合相关联的信道中包含的内容，这里，与SIB1相关联的信道包括承载SIB1的调度信息的PDCCH和承载SIB1的PDSCH，与第一***信息块集合相关联的信道包括承载第一***信息块集合的调度信息的PDCCH和承载第一***信息块集合所包含的指示一个第一信息块的PDSCH。

在本申请实施例中，终端设备可基于网络设备下发的指示信息确定***信息是否发生更新，从而只接收发生更新的***信息。这样就可避免相同的***信息的重复获取，降低了终端设备获取***信息所产生的功耗，提升了终端设备的***信息的获取效率和用户体验。
