  • the present application relates to the field of wireless communication, and in particular, to a paging method and apparatus.
  • a terminal In a communication system, a terminal is usually in a standby state. When the terminal is in a standby state, it will periodically detect a paging message, and use the paging message to determine whether it needs to establish a connection with a network device. For example, when the terminal is in the standby state, it will detect the physical downlink control channel (PDCCH) used to carry the paging message, and receive the physical downlink shared channel (physical downlink shared channel) carrying the terminal identifier according to the PDCCH. PDSCH). If the terminal identifier carried in the PDSCH includes the terminal identifier, it is determined that the terminal is paged. Subsequently, the terminal will establish a connection with the network device. In the above process, after detecting the PDCCH, the terminal also needs to detect the PDSCH to determine whether it is paged. Therefore, the power consumption of the terminal to receive the paging message is relatively high.

Description

寻呼方法及装置
“本申请要求于2020年7月31日提交国家知识产权局、申请号为202010761340.1、发明名称为“寻呼方法及装置”的专利申请的优先权，其全部内容通过引用结合在本申请中”。
技术领域
本申请涉及无线通信领域，尤其涉及寻呼方法及装置。
背景技术
在通信系统中，终端通常处于待机状态。终端在处于待机状态时，会周期性地检测寻呼消息，并通过该寻呼消息来确定是否需要与网络设备建立连接。例如，终端处于待机状态时，会检测用于承载寻呼消息的物理下行控制信道(physical downlink control channel，PDCCH)，并根据该PDCCH接收承载了终端标识的物理下行共享信道(physical downlink shared channel，PDSCH)。若PDSCH中承载的终端标识包括该终端的标识，则确定该终端被寻呼。后续，该终端会与网络设备建立连接。在上述过程中，终端检测到PDCCH后，还需要检测PDSCH，才能确定自己是否被寻呼。因此，终端接收寻呼消息的功耗较高。
为了降低终端接收寻呼消息的功耗，可以在PDCCH中承载终端标识。如此，终端检测到PDCCH后就可以确定自己是否被寻呼。然而，终端如何兼容上述两种寻呼方式，是目前亟需解决的问题。
发明内容
本申请提供寻呼方法及装置，终端能够兼容两种寻呼方式。
为达到上述目的，本申请的实施例采用如下技术方案：
第一方面，本申请实施例提供一种寻呼方法，该方法包括：从网络设备接收寻呼PDCCH；当该寻呼PDCCH为第一类型的寻呼PDCCH时，根据该第一类型的寻呼PDCCH确定是否被寻呼；当该寻呼PDCCH为第二类型的寻呼PDCCH时，接收寻呼PDSCH，根据该寻呼PDSCH确定是否被寻呼。
上述第一方面提供的方法，终端可以从网络设备接收寻呼PDCCH，并当该寻呼PDCCH为第一类型的寻呼PDCCH时，根据第一类型的寻呼PDCCH确定是否被寻呼；当该寻呼PDCCH为第二类型的寻呼PDCCH时，根据第二寻呼PDCCH接收寻呼PDSCH，根据寻呼PDSCH确定是否被寻呼。如此，终端可以兼容第一类型的寻呼PDCCH和第二类型的寻呼PDCCH。网络设备也可以根据需要确定寻呼终端的方式，而不是仅使用单一的方式寻呼终端。
一种可能的实现方式，该第一类型的寻呼PDCCH和该第二类型的寻呼PDCCH的大小相同。基于上述方法，可以降低终端盲检寻呼PDCCH的复杂度。
一种可能的实现方式，该第一类型的寻呼PDCCH和第二类型的寻呼PDCCH采用不同的加扰方式。基于上述方法，第一类型的寻呼PDCCH和第二类型的寻呼PDCCH的加扰方式不同，因此，终端可以根据加扰方式来确定寻呼PDCCH的类型，从而可以正确解析该寻呼PDCCH。
一种可能的实现方式，该寻呼PDCCH包括寻呼类型指示信息，该寻呼类型指示信息用于指示该寻呼PDCCH的类型。基于上述方法，终端可以根据寻呼类型指示信息确定寻呼PDCCH的类型，从而可以正确解析该寻呼PDCCH。
一种可能的实现方式，该寻呼类型指示信息占用该寻呼PDCCH的最低的N个比特位，N为正数。基于上述方法，对于支持第二类型的寻呼PDCCH的终端来说，第二类型的寻呼PDCCH的低位比特位保留比特，终端可以不用识别，对于支持第一类型的寻呼PDCCH的终端来说，可以根据寻呼类型指示信息确定寻呼PDCCH的类型，因此，兼容性较好。
一种可能的实现方式，该方法还包括：从该网络设备接收通知消息，该通知消息用于指示该寻呼PDCCH的类型。基于上述方法，终端可以从网络设备接收用于指示寻呼PDCCH的类型的通知消息，从而可以根据该通知消息确定寻呼PDCCH的类型。
一种可能的实现方式，该通知消息还用于指示在一个寻呼机会内能够检测到的寻呼PDCCH的数量。基于上述方法，终端可以通过通知消息确定在一个寻呼机会内能够检测到的寻呼PDCCH的数量。如此，在一个寻呼机会内，终端接收到通知消息中指示的数量的寻呼PDCCH后，可以停止接收寻呼PDCCH，以便降低终端的功耗。
一种可能的实现方式，该通知消息为高层信令。基于上述方法，终端可以通过高层信令接收该通知消息，以便终端确定寻呼PDCCH的类型。
一种可能的实现方式，该第一类型的寻呼PDCCH包括一个终端的标识，该寻呼PDSCH包括至少一个终端的标识。基于上述方法，第一类型的寻呼PDCCH中包括一个终端的标识，所以该第一类型的寻呼PDCCH和该第二类型的寻呼PDCCH的大小可以相同，从而可以降低终端盲检寻呼PDCCH的复杂度。另外，终端还可以使用与第二类型的寻呼PDCCH相同的加扰方式，以便进一步降低终端盲检寻呼PDCCH的复杂度。
一种可能的实现方式，该第二类型的寻呼PDCCH不包括终端的标识。基于上述方法，第二类型的寻呼PDCCH不包括终端的标识，因此，终端需要根据第二类型的寻呼PDCCH接收包括终端标识的寻呼PDSCH。

一种可能的实现方式，该寻呼PDCCH中包括的终端的标识为第一类型的标识或第二类型的标识，该寻呼PDSCH中包括的终端的标识为第二类型的标识，该第一类型的标识为该第二类型的标识的一部分。基于上述方法，寻呼PDCCH中包括的终端的标识可以是多种类型的标识。
一种可能的实现方式，该第二类型的标识为5G服务临时移动用户标识(5G S-temporary mobile subscriber identity，5G-S-TMSI)或非激活无线网络临时标识(inactive radio network temporary identifier，I-RNTI)。基于上述方法，寻呼PDCCH可以包括5G-S-TMSI、I-RNTI、5G-S-TMSI的一部分或I-RNTI的一部分，以便终端确定是否被寻呼。
一种可能的实现方式，当该寻呼PDCCH为第一类型的寻呼PDCCH时，在该寻呼PDCCH所在的寻呼机会内，待寻呼的终端的数量小于或等于第一阈值；或者，该网络设备的服务覆盖范围小于或等于第二阈值；或者，该网络设备的业务量小于或等于第三阈值；该网络设备的位置与城市中心的位置之间的距离大于或等于第四阈值；或者，待寻呼的终端处于非激活状态；或者；待寻呼终端的寻呼标识为I-RNTI。基于上述方法，当寻呼PDCCH所在的寻呼机会内，待寻呼的终端的数量小于或等于第一阈值；或者，该网络设备的服务覆盖范围小于或等于第二阈值；或者，该网络设备的业务量小于或等于第三阈值；该网络设备的位置与城市中心的位置之间的距离大于或等于第四阈值时，网络设备通过第一类型的寻呼PDCCH寻呼终端；或者，当该待寻呼的终端处于非激活状态时，网络设备通过第一类型的寻呼PDCCH寻呼终端；或者，当待寻呼终端的寻呼标识为I-RNTI时，网络设备通过第一类型的寻呼PDCCH寻呼终端。
第二方面，本申请实施例提供一种寻呼方法，该方法包括：确定寻呼PDCCH；当该寻呼PDCCH为第一类型的寻呼PDCCH时，向终端发送该寻呼PDCCH；当该寻呼PDCCH为第二类型的寻呼PDCCH时，向该终端发送该寻呼PDCCH，向该终端发送寻呼PDSCH。

在本申请实施例中，寻呼方法的执行主体的具体结构，本申请实施例并未特别限定，只要可以通过运行记录有本申请实施例的寻呼方法的代码的程序，以根据本申请实施例的寻呼方法进行通信即可，例如，本申请实施例提供的寻呼方法的执行主体可以是网络设备，或者为应用于网络设备中的部件，例如，芯片，本申请对此不进行限定。或者，本申请实施例提供的寻呼方法的执行主体可以是终端，或者为应用于终端的部件，例如，芯片，本申请对此不进行限定。下述实施例以寻呼方法的执行主体分别为网络设备、终端为例进行描述。
如图3所示，为本申请实施例提供的一种寻呼方法，该寻呼方法包括步骤301-步 骤303。
步骤301：网络设备确定寻呼PDCCH。
其中，网络设备可以为图1中的网络设备101。
其中，寻呼PDCCH可以为第一类型的寻呼PDCCH，或者第二类型的寻呼PDCCH。第一类型的寻呼PDCCH可以包括一个终端的标识。若有多个终端被寻呼，网络设备需要确定多个寻呼PDCCH，每个寻呼PDCCH包括一个终端的标识。第二类型的寻呼PDCCH不包括终端的标识。
一种可能的实现方式，第一类型的寻呼PDCCH包括的终端的标识为第一类型的标识或第二类型的标识。其中，第一类型的标识为第二类型的标识的一部分。可以理解为，在第二类型的标识中截取一部分作为第一类型的标识。例如，第一类型的标识为第二类型的标识的高M位。M为正整数。第二类型的标识可以为5G服务临时移动用户标识(5G S-temporary mobile subscriber identity，5G-S-TMSI)或非激活无线网络临时标识(inactive radio network temporary identifier，I-RNTI)等。
示例性的，以终端的标识的比特位为R比特，第一类型的寻呼PDCCH的有效载荷(payload)大小为K比特为例，如果R大于等于K，则M＝K。在这种情况下，第一类型的寻呼PDCCH包括第一类型的标识。如果R小于K，则M＝R。在这种情况下，第一类型的寻呼PDCCH包括第二类型的标识。此时，第一类型的寻呼PDCCH中除了包括第二类型的标识外，还包括(K-R)比特的保留比特，保留比特位于第一类型寻呼PDCCH的低位。
请参考表1，表1给出了第一类型寻呼PDCCH有效载荷大小、终端的标识的比特位、M的取值以及第一类型寻呼PDCCH中的保留比特的几种示例，表1中，各数字的单位均为比特。表1中，第一类型寻呼PDCCH有效载荷大小为39比特，终端的标识的比特位为48比特时，第一类型的寻呼PDCCH包括第一类型的标识，M为39比特，第一类型寻呼PDCCH中的保留比特为0比特，即第一类型寻呼PDCCH不包括保留比特。第一类型寻呼PDCCH有效载荷大小为39比特，终端的标识的比特位为41比特时，第一类型的寻呼PDCCH包括第一类型的标识，M为39比特，第一类型寻呼PDCCH中的保留比特为0比特。第一类型寻呼PDCCH有效载荷大小为42比特，终端的标识的比特位为41比特时，第一类型的寻呼PDCCH包括第二类型的标识，M为41比特，第一类型寻呼PDCCH中的保留比特为1比特。第一类型寻呼PDCCH有效载荷大小为44比特，终端的标识的比特位为41比特时，第一类型的寻呼PDCCH包括第二类型的标识，M为41比特，第一类型寻呼PDCCH中的保留比特为3比特。
表1

需要说明的是，一个终端在特定的寻呼机会中检测寻呼消息，寻呼机会根据该终 端标识的低L位来确定，其中，L为正整数。因此，若第一类型的寻呼PDCCH包括第一类型的标识，只要(L+M)大于等于第二类型标识的比特位，是不会造成虚假寻呼或错误寻呼的。例如，若终端的标识为41位，该终端的寻呼机会由终端标识的低10比特来确定，若网络设备确定寻呼该终端，则第一类型的寻呼PDCCH包括该终端的标识中高41-10＝31位即可。
一种可能的实现方式，第二类型的寻呼PDCCH包括用于接收寻呼PDSCH的物理层信令，例如，寻呼PDSCH的时频资源等信息。
示例性的，第二类型的寻呼PDCCH包括如下信息的一个或者多个：短消息指示(short message indicator)、短消息、频域资源指示、时域资源指示、虚拟资源块(virtual resource block，VRB)到物理资源块(physical resource block，PRB)映射(VRB-to-PRB mapping)方式指示、调制编码方式、传输块缩放值和保留比特等等。其中，短消息指示、短消息、频域资源指示、时域资源指示、VRB-to-PRB mapping方式指示、调制编码方式、传输块缩放值和保留比特的介绍可以参考常规技术中的解释说明，不予赘述。
一种可能的实现方式，第一类型的寻呼PDCCH和第二类型的寻呼PDCCH的大小相同。例如，第一类型的寻呼PDCCH和第二类型的寻呼PDCCH的有效载荷(payload)的大小相同，从而可以降低终端盲检寻呼PDCCH的复杂度。
示例性的，第一类型寻呼PDCCH和第二类型的寻呼PDCCH的格式可以如图4所示。图4中，第一类型的寻呼PDCCH包括第一类型的标识或第二类型的标识，第二类型的寻呼PDCCH包括短消息指示、短消息、频域资源指示、时域资源指示、VRB-to-PRB mapping方式指示、调制编码方式、传输块缩放值和保留比特。
进一步的，对于相同的DL带宽部分(band width part，BWP)，第一类型寻呼PDCCH和第二类型的寻呼PDCCH的大小相同。
示例性的，不同的DL BWP对应的第一类型寻呼PDCCH和第二类型的寻呼PDCCH的大小可以如表2所示。表2中，当DL BWP为12RB，频域资源指示比特位宽为7比特时，第一类型寻呼PDCCH和第二类型的寻呼PDCCH的大小都为35比特。当DL BWP为24RB，频域资源指示比特位宽为9比特时，第一类型寻呼PDCCH和第二类型的寻呼PDCCH的大小都为37比特。当DL BWP为48RB，频域资源指示比特位宽为11比特时，第一类型寻呼PDCCH和第二类型的寻呼PDCCH的大小都为39比特。当DL BWP为96RB，频域资源指示比特位宽为13比特时，第一类型寻呼PDCCH和第二类型的寻呼PDCCH的大小都为41比特。
表2
Figure PCTCN2021109527-appb-000002
需要说明的是，表2仅是第一类型寻呼PDCCH和第二类型的寻呼PDCCH的大小的示例，在实际应用中，第一类型寻呼PDCCH和第二类型的寻呼PDCCH的大小还可 以是其他值，不予限制。
需要说明的是，第一类型的寻呼PDCCH和第二类型的寻呼PDCCH的加扰方式可以相同也可以不同。例如，第二类型的寻呼PDCCH可以采用寻呼无线网络临时标识符(paging radio network temporary identifier，P-RNTI)加扰，第一类型的寻呼PDCCH可以采用不同于P-RNTI的RNTI加扰。若第一类型的寻呼PDCCH和第二类型的寻呼PDCCH的加扰方式相同，可以进一步的降低终端盲检寻呼PDCCH的复杂度。
一种可能的实现方式，寻呼PDCCH包括寻呼类型指示信息。该寻呼类型指示信息用于指示寻呼PDCCH的类型。
可以理解的，该寻呼类型指示信息可以包括在第一类型的寻呼PDCCH中，不包括在第二类型的寻呼PDCCH中；或者，该寻呼类型指示信息可以包括在第二类型的寻呼PDCCH中，不包括在第一类型的寻呼PDCCH中；或者，该指示信息可以既包括在第一类型的寻呼PDCCH中，又包括在第二类型的寻呼PDCCH中。
示例性的，该寻呼类型指示信息为1比特指示信息。例如，寻呼类型指示信息为1时，指示寻呼PDCCH的为第一类型的寻呼PDCCH，寻呼类型指示信息为0时，指示寻呼PDCCH的为第二类型的寻呼PDCCH，反之亦然。
进一步的，该寻呼类型指示信息占用寻呼PDCCH的最低的N个比特，N为正数。
示例性的，如图5所示，对于第一类型的寻呼PDCCH，寻呼类型指示信息占用寻呼PDCCH的最低的N个比特，对于第二类型的寻呼PDCCH，寻呼类型指示信息占用寻呼PDCCH的保留比特中的比特。对于支持第二类型的寻呼PDCCH的终端来说，第二类型的寻呼PDCCH的低位比特位保留比特，终端可以不用识别，对于支持第一类型的寻呼PDCCH的终端来说，可以根据寻呼类型指示信息确定寻呼PDCCH的类型，因此，兼容性较好。
示例性的，以终端的标识的比特位为R比特，第一类型的寻呼PDCCH的有效载荷(payload)大小为K比特为例，如果R大于等于K，则M＝(K-N)。在这种情况下，第一类型的寻呼PDCCH包括第一类型的标识。如果R小于K，则M＝R。在这种情况下，第一类型的寻呼PDCCH包括第二类型的标识。此时，第一类型的寻呼PDCCH中除了包括第二类型的标识外，还包括(K-R-N)比特的保留比特，保留比特位于第一类型寻呼PDCCH的低位。
请参考表3，表3给出了N＝1时，第一类型寻呼PDCCH有效载荷大小、终端的标识的比特位、M的取值以及第一类型寻呼PDCCH中的保留比特的几种示例性的说明，表3中，各数字的单位均为比特。表3中，第一类型寻呼PDCCH有效载荷大小为39比特，终端的标识的比特位为48比特时，第一类型的寻呼PDCCH包括第一类型的标识，M为38比特，第一类型寻呼PDCCH中的保留比特为0比特，即第一类型寻呼PDCCH不包括保留比特。第一类型寻呼PDCCH有效载荷大小为39比特，终端的标识的比特位为41比特时，第一类型的寻呼PDCCH包括第一类型的标识，M为38比特，第一类型寻呼PDCCH中的保留比特为0比特。第一类型寻呼PDCCH有效载荷大小为42比特，终端的标识的比特位为41比特时，第一类型的寻呼PDCCH包括第二类型的标识，M为41比特，第一类型寻呼PDCCH中的保留比特为0比特。第一类型寻呼PDCCH有效载荷大小为44比特，终端的标识的比特位为41比特时，第 一类型的寻呼PDCCH包括第二类型的标识，M为41比特，第一类型寻呼PDCCH中的保留比特为2比特。

一种可能的实现方式，网络设备通过下述示例性的方式确定寻呼PDCCH：
方式1：网络设备根据待寻呼终端的数量确定寻呼PDCCH。总体而言，待寻呼的终端设备的数量较少时，网络设备确定的寻呼PDCCH为第一类型的寻呼PDCCH；待寻呼的终端设备的数量较多时，网络设备确定的寻呼PDCCH为第二类型的寻呼PDCCH。
示例性的，在寻呼PDCCH所在的寻呼机会内，待寻呼的终端的数量小于或等于第一阈值，网络设备确定的寻呼PDCCH为第一类型的寻呼PDCCH；待寻呼的终端的数量大于第一阈值，网络设备确定的寻呼PDCCH为第二类型的寻呼PDCCH。其中，寻呼机会的介绍可以参考常规技术中的解释说明。以第一阈值为4为例，在寻呼PDCCH所在的寻呼机会内，若待寻呼终端的数量为3，则网络设备确定的寻呼PDCCH为第一类型的寻呼PDCCH，若待寻呼终端的数量为5，则网络设备确定的寻呼PDCCH为第二类型的寻呼PDCCH。
方式2：网络设备根据网络设备的服务覆盖范围确定寻呼PDCCH。总体而言，网络设备的服务覆盖范围较小时，网络设备确定的寻呼PDCCH为第一类型的寻呼PDCCH；网络设备的服务覆盖范围较大时，网络设备确定的寻呼PDCCH为第二类型的寻呼PDCCH。
示例性的，网络设备的服务覆盖范围小于或等于第二阈值，网络设备确定的寻呼PDCCH为第一类型的寻呼PDCCH；网络设备的服务覆盖范围大于第二阈值，网络设备确定的寻呼PDCCH为第二类型的寻呼PDCCH。例如，若网络设备为服务覆盖范围小于第二阈值的微基站，则该网络设备确定的寻呼PDCCH为第一类型的寻呼PDCCH；若网络设备为服务覆盖范围大于第二阈值的宏基站，则该网络设备确定的寻呼PDCCH为第二类型的寻呼PDCCH。
方式3：网络设备根据业务量确定寻呼PDCCH。总体而言，网络设备的业务量较少时，网络设备确定的寻呼PDCCH为第一类型的寻呼PDCCH；网络设备的业务量较多时，网络设备确定的寻呼PDCCH为第二类型的寻呼PDCCH。
示例性的，网络设备的业务量小于或等于第三阈值，网络设备确定的寻呼PDCCH为第一类型的寻呼PDCCH；网络设备的业务量大于第三阈值，网络设备确定的寻呼PDCCH为第二类型的寻呼PDCCH。例如，白天的业务量大于第三阈值，网络设备确定的寻呼PDCCH为第二类型的寻呼PDCCH；夜晚的业务量小于第三阈值，网络设备确定的寻呼PDCCH为第一类型的寻呼PDCCH。
方式4：网络设备根据网络设备的位置确定寻呼PDCCH。总体而言，网络设备的位置处于人口密度较低的地区(例如，郊区)时，网络设备确定的寻呼PDCCH为第一类型的寻呼PDCCH；网络设备的位置处于人口密度较高的地区(例如，市区)时，网络设备确定的寻呼PDCCH为第二类型的寻呼PDCCH。
示例性的，网络设备的位置与城市中心的位置之间的距离大于或等于第四阈值，网络设备确定的寻呼PDCCH为第一类型的寻呼PDCCH；网络设备的位置与城市中心的位置之间的距离小于第四阈值，网络设备确定的寻呼PDCCH为第二类型的寻呼PDCCH。以第四阈值为30km为例，网络设备在城市中心时，网络设备确定的寻呼PDCCH为第二类型的寻呼PDCCH；网络设备在距离城市中心40km的远郊时，网络设备确定的寻呼PDCCH为第一类型的寻呼PDCCH。或者，网络设备按照其位置被划分为属于人口密度较低的地区，或者被划分为属于人口密度较高的地区。被划分为属于人口密度较低的地区的网络设备确定的寻呼PDCCH为第一类型的寻呼PDCCH，被划分为属于人口密度较高的地区的网络设备确定的寻呼PDCCH为第二类型的寻呼PDCCH。
方式5：网络设备根据待寻呼终端的状态确定寻呼PDCCH。
一种可能的实现方式，当待寻呼终端处于非激活(Inactive)状态时，网络设备确定通过第一类型的寻呼PDCCH寻呼终端。当待寻呼终端处于空闲(Idle)状态或者链接(Connected)状态时，网络设备确定通过第二类型的寻呼PDCCH寻呼终端。
可以理解的，当终端处于非激活状态时，网络设备会根据I-RNTI确定终端的寻呼标识。当终端处于空闲状态或者链接状态，网络设备根据5G-S-TMSI确定终端的寻呼标识。其中，寻呼标识为网络设备寻呼终端时采用的标识，例如，第一类型的标识或第二类型的标识。I-RNTI的比特大小为41比特，5G-S-TMSI的比特大小为48比特，I-RNTI的比特位小于5G-S-TMSI。因此，若寻呼标识是根据I-RNTI确定的，则采用第一类型寻呼PDCCH寻呼终端通常不会造成终端误寻呼。此时，网络设备确定采用第一类型的寻呼PDCCH寻呼终端。而5G-S-TMSI比特位比较大，在寻呼PDCCH有效载荷大小较小时，可能会造成终端误寻呼，此时，网络设备确定采用第二类型的寻呼PDCCH寻呼终端。
方式6：网络设备根据寻呼标识确定寻呼PDCCH。
示例性的，当待寻呼终端的寻呼标识是I-RNTI时，网络设备确定通过第一类型的寻呼PDCCH寻呼终端。当待寻呼终端的寻呼标识是5G-S-TMSI时，网络设备确定通过第二类型的寻呼PDCCH寻呼终端。
方式7：网络设备根据第二类型的标识，以及寻呼PDCCH有效载荷大小确定寻呼PDCCH。
一种可能的实现方式，若第二类型的标识的比特位，减去第二类型的标识中用于确定寻呼机会的L比特，再加上寻呼类型指示信息的N比特得到的比特位，小于等于PDCCH有效载荷大小，则网络设备确定通过第一类型的寻呼PDCCH寻呼终端。当第二类型的标识的比特位，减去第二类型的标识中用于确定寻呼机会的L比特，再加上寻呼类型指示信息的N比特得到的比特位，大于PDCCH有效载荷大小，则网络设备确定通过第二类型的寻呼PDCCH寻呼终端。
示例性的，以第二类型的标识为I-RNTI，L为10比特，N为1比特为例，41-10+1＝32比特，如果寻呼PDCCH的有效载荷大小为37比特，32<37，则网络设备确定采用第一类型的寻呼PDCCH。以第二类型的标识为5G-S-TMSI，L为10比特，N为1比特为例，48-10+1＝39比特，如果寻呼PDCCH的有效载荷大小为37比特，39>37，则网络设备确定采用第二类型寻呼PDCCH。
可以理解的，若寻呼PDCCH中不包括寻呼类型指示信息，则网络设备在确定寻呼PDCCH时，不参考寻呼类型指示信息的N比特。示例性的，若第二类型的标识的比特位，减去第二类型的标识中用于确定寻呼机会的L比特得到的比特位，小于等于PDCCH有效载荷大小，则网络设备确定通过第一类型的寻呼PDCCH寻呼终端。当第二类型的标识的比特位，减去第类型的标识中用于确定寻呼机会的L比特得到的比特位，大于PDCCH有效载荷大小，则网络设备确定通过第二类型的寻呼PDCCH寻呼终端。
可以理解的，一个网络设备为不同的终端可以确定不同类型的寻呼PDCCH。例如，网络设备为终端1确定的寻呼PDCCH为第一类型的寻呼PDCCH，为终端2确定的寻呼PDCCH为第二类型的寻呼PDCCH。
可以理解的，本申请实施例不限制网络设备确定的寻呼PDCCH的数量。也就是说，网络设备确定的寻呼PDCCH的数量可以是一个或多个。网络设备确定的寻呼PDCCH的数量为多个时，该多个寻呼PDCCH可以都是第一类型的寻呼PDCCH，也可以都是第二类型的寻呼PDCCH，还可以既包括第一类型的寻呼PDCCH，也包括第二类型的寻呼PDCCH。
需要说明的，步骤301之前，网络设备还可以从终端接收寻呼PDCCH的类型的指示信息。该寻呼PDCCH的类型的指示信息用于指示终端支持的寻呼PDCCH的类型。如此，网络设备可以根据需要确定寻呼终端的方式。
步骤302：网络设备向终端发送寻呼PDCCH。
其中，该终端可以为图1中的终端。例如，该终端为图1中的终端102，和/或，终端103，和/或，终端104。
对应的，终端从网络设备接收寻呼PDCCH。
步骤303：终端根据寻呼PDCCH确定是否被寻呼。
可以理解的，终端在确定是否被寻呼之前，要确定接收到的寻呼PDCCH是那种类型的寻呼PDCCH。示例性的，终端可以通过以下三种方法确定寻呼PDCCH的类型：
方法1：终端根据加扰方式确定寻呼PDCCH的类型。
一种可能的实现方式，第一类型的寻呼PDCCH和第二类型的PDCCH的加扰方式不同，终端在解扰寻呼PDCCH时，若通过第一类型的寻呼PDCCH对应的加扰方式解扰出寻呼PDCCH，则终端确定接收到的是第一类型的寻呼PDCCH；若通过第二类型的寻呼PDCCH对应的加扰方式解扰出寻呼PDCCH，则终端确定接收到的是第二类型的寻呼PDCCH。
方式2：终端根据上述寻呼类型指示信息确定寻呼PDCCH的类型。
一种可能的实现方式，若寻呼PDCCH包括寻呼类型指示信息，终端根据寻呼类型指示信息确定寻呼PDCCH的类型。例如，若该寻呼类型指示信息为1，则终端确定 接收到的是第一类型的寻呼PDCCH；若该寻呼类型指示信息为0，则终端确定接收到的是第二类型的寻呼PDCCH，反之亦然。
方式3：终端通过网络设备发送的通知消息确定寻呼PDCCH的类型。
一种可能的实现方式，步骤302之前，终端从网络设备接收用于指示寻呼PDCCH的类型的通知消息，从而根据该通知消息确定寻呼PDCCH的类型。具体的，可以参考下述图6所示的方法。可以理解的，对于方式3，寻呼PDCCH可以不包括上述寻呼类型指示信息，和/或，第一类型的寻呼PDCCH和第二类型的寻呼PDCCH的加扰方式相同。
可以理解的，终端确定了寻呼PDCCH的类型后，可以解析该寻呼PDCCH，从而根据该寻呼PDCCH确定终端是否被寻呼。
一种可能的实现方式，当寻呼PDCCH为第一类型的寻呼PDCCH时，终端根据第一类型的寻呼PDCCH确定是否被寻呼；当寻呼PDCCH为第二类型的寻呼PDCCH时，终端根据第二类型的寻呼PDCCH接收寻呼PDSCH；终端根据寻呼PDSCH确定是否被寻呼。
进一步的，终端根据第一类型的寻呼PDCCH确定是否被寻呼，包括：若第一类型的寻呼PDCCH包括该终端的标识，确定该终端被寻呼；若寻呼PDCCH所在的寻呼机会内的寻呼PDCCH中均不包括该终端的标识，则确定该终端未被寻呼。其中，该终端的标识也可以替换为该终端对应的第一类型的标识。
可以理解的，若寻呼PDCCH为第二类型的寻呼PDCCH，终端还需要根据第二类型的寻呼PDCCH中的频域资源指示和时域资源指示等信息从网络设备接收寻呼PDSCH，再根据寻呼PDSCH确定终端是否被寻呼。
其中，寻呼PDSCH包括至少一个终端的标识。
进一步的，终端根据寻呼PDSCH确定是否被寻呼，包括：若寻呼PDSCH包括该终端的标识，确定该终端被寻呼；若寻呼PDSCH中不包括该终端的标识，则确定该终端未被寻呼。
基于图3所示的方法，网络设备可以确定寻呼PDCCH，并向终端发送该寻呼PDCCH。终端接收到该PDCCH后，确定该PDCCH的类型，当寻呼PDCCH为第一类型的寻呼PDCCH时，根据第一类型的寻呼PDCCH确定终端是否被寻呼；当寻呼PDCCH为第二类型的寻呼PDCCH时，接收寻呼PDSCH，根据寻呼PDSCH确定终端是否被寻呼。如此，终端可以兼容第一类型的寻呼PDCCH和第二类型的寻呼PDCCH。网络设备也可以根据需要确定寻呼终端的方式，而不是仅使用单一的方式寻呼终端。
在图3所示方法的一种可能的实现方式中，网络设备通过向终端发送通知消息指示后续网络设备发送的寻呼PDCCH的类型。终端接收到该通知消息后可以根据该通知消息确定终端接收到的寻呼PDCCH的类型。具体的，如图6所示，图3所示的方法还包括步骤601和步骤602。
步骤601：网络设备向终端发送通知消息。
其中，该通知消息用于指示寻呼PDCCH的类型。例如，通知消息包括1比特信息，该1比特信息为1时，该通知消息指示寻呼PDCCH的类型为第一类型的寻呼PDCCH，若该1比特信息为0时，该通知消息指示寻呼PDCCH的类型为第二类型的 寻呼PDCCH，反之亦然。
进一步的，该通知消息还用于指示在一个寻呼机会内能够检测到的寻呼PDCCH的数量Q，Q为正数。如此，在一个寻呼机会内，终端检测到Q个寻呼PDCCH后，终端可以停止检测寻呼PDCCH，以便降低终端的功耗。
一种可能的实现方式，该通知消息为高层信令，例如，无线资源控制(radio resource control，RRC)层信令。
可以理解的，上述Q也可以是预定义的。例如，上述Q可以是协议中定义的。
步骤602：终端根据通知消息确定寻呼PDCCH的类型。
