Description

通信方法、无线接入网设备及终端设备 技术领域
本申请涉及通信技术，并且更具体地，尤其涉及一种通信方法、无线接入网设备及终端设备。
背景技术
寻呼(paging)可以用于通知终端设备建立业务；或者，用于通知终端设备小区系统信息发生改变，以使终端设备重新读取改变后的系统广播消息；或者，用于通知终端设备接收地震海啸告警系统(earthquake and tsunami warning system，ETWS)信息。
寻呼消息的发送和接收时机需要根据寻呼参数确定，无线接入网设备使用寻呼参数计算出寻呼时机，并利用该寻呼时机发送寻呼消息。终端设备则使用相同的寻呼参数和计算方式，计算出寻呼时机，并在该寻呼时机上接收寻呼消息。
现有技术中，寻呼参数需要预先通过人工方式进行配置，配置完成后，无线接入网设备按照所配置的寻呼参数确定发送寻呼消息的寻呼时机，并在该寻呼时机上发送寻呼消息。
但是，现有寻呼机制会导致寻呼时隙的开销过大以及寻呼能耗的开销过大。
发明内容
本申请实施例提供一种通信方法、无线接入网设备及终端设备，用于解决现有技术中寻呼时隙的开销过大以及寻呼能耗的开销过大的问题。
第一方面，本申请实施例提供一种通信方法，该方法包括：
无线接入网设备根据第一信息和第二信息，确定寻呼周期组包含的寻呼周期数量以及寻呼信息在该寻呼周期组中的发送位置，并且，在该发送位置上发送寻呼信息。其中，该寻呼周期组中包括至少一个寻呼周期，寻呼周期组中不同寻呼时机服务于不同终端设备。第一信息用于指示设定时间内来自核心网设备的寻呼消息峰值，第二信息用于指示无线接入网设备的寻呼能力。
在该方法中，由第一信息所指示的设定时间内来自核心网设备的寻呼消息以及无线接入网设备产生的寻呼消息的峰值能够体现需要无线接入网设备处理的寻呼消息数量，即无线接入网设备的寻呼负载，由第二信息所指示的寻呼能力能够体现接入网设备在单位时间内能够处理的寻呼消息数量。该两种信息能够体现无线接入网的系统状态。同时，无线接入网设备将至少一个寻呼周期组成一个寻呼周期组，该寻呼周期组中不同的寻呼时机服务于不同的终端设备。在不同的系统状态下，寻呼周期组所包含的寻呼周期的数量可以不同。无线接入网设备可以根据第一信息和第二信息所表示的系统状态确定寻呼周期组的长度以及寻呼信息在该寻呼周期组中的发送位置。当寻呼负载较小时，无线接入网设备可以将寻呼周期组的长度调整为大于当前的长度，同时，对于一个终端设备来说，在调整后的寻呼周期组中仍然仅占用一个寻呼时机，因此，能够使得无线接入网设备用于寻呼的密度变 小，进而使得寻呼时机与系统状态匹配，可以在低的寻呼负载时减少寻呼时隙，以降低寻呼时隙以及寻呼能耗的开销。可选的，按照上述实现方式，可以不需要通知终端设备该无线接入网设备最后确定出的该发送位置，终端设备可以根据最初该无线接入网设备下发的寻呼参数就可以实现被寻呼，从而节省信令开销。
作为一种可能的实现方式，无线接入网设备可以确定寻呼周期组包含的寻呼周期数量以及寻呼信息在寻呼周期组中的发送位置。
其中，第三信息用于指示所述无线接入网设备的系统负载。
在该方式中，第三信息能够体现无线接入网设备的系统负载，结合系统负载确定寻呼周期组所包括寻呼周期数量以及发送位置，使得无线接入网设备用于寻呼的发送位置数量与系统负载匹配。
在该可能的实现方式中，当上述系统负载小于第一预设阈值时，无线接入网设备根据第一信息和第二信息，确定寻呼周期组包含的寻呼周期数量以及寻呼信息在所述寻呼周期组中的发送位置。
在该方式中，如果系统负载小于上述第一预设阈值，则说明无线接入网设备当前的系统负载较小，在这种情况下，无线接入网设备才根据第一信息和第二信息重新确定寻呼周期组包含的寻呼周期数量以及寻呼信息在该寻呼周期组中的发送位置，进而可以在寻呼负载较小时降低寻呼时隙和寻呼能力。而当无线接入网设备当前的系统负载已经较大，此时，即使寻呼负载较小并减小了寻呼时隙的占用，原来的寻呼时隙也可能被用于数据传输，以支撑较大的系统负载，而系统能耗并不能得到降低。因此，无线接入网设备仅在系统负载小于第一预设阈值时，才根据第一信息和第二信息重新确定寻呼周期组包含的寻呼周期数量以及寻呼信息在该寻呼周期组中的发送位置，从而确定出与系统负载和寻呼负载匹配的寻呼周期组，以使得寻呼周期组长度的调整能够真正降低寻呼时隙和寻呼能耗的开销。
作为一种可能的实现方式，如果上述寻呼消息峰值与上述寻呼能力的比值小于第二预设阈值，则无线接入网设备确定寻呼信息的发送位置为第一寻呼周期组中的位置。
其中，在该可能的实现方式中，上述第一寻呼周期组所包括的寻呼周期数量大于无线接入网设备当前使用的寻呼周期组所包括的寻呼周期数量。
在该方式中，如果上述寻呼消息峰值与上述寻呼能力的比值小于第二预设阈值，则说明寻呼的负载状态趋向更小负载，在这种情况下，确定的第一寻呼周期组所包含的寻呼周期数量大于当前正在使用的寻呼周期组所包含的寻呼周期数量，即寻呼时机密度变小，基于该第一寻呼周期组进行寻呼，可以减少时隙开销以及能耗开销。
作为一种可能的实现方式，如果上述寻呼消息峰值与上述寻呼能力的比值大于第三预设阈值，则无线接入网设备确定寻呼信息的发送位置为第二寻呼周期组中的位置。
其中，在该可能的实现方式中，上述第二寻呼周期组所包括的寻呼周期数量小于所述无线接入网设备当前使用的寻呼周期组所包括的寻呼周期数量。
在该方式中，如果上述寻呼消息峰值与上述寻呼能力的比值大于第三预设阈值，则说明寻呼的负载状态趋向更大负载，在这种情况下，确定的二寻呼周期组所包含的寻呼周期数量小于当前正在使用的寻呼周期组所包含的寻呼周期数量，即寻呼时机密度变大，基于该第二寻呼周期组进行寻呼，可以避免出现资源不足所导致的消息延迟等。
第二方面，本申请实施例提供一种通信方法，该方法包括：

在该方式中，根据第三信息确定寻呼周期组所包括寻呼周期数量以及发送位置，能够满足实际的系统负载需求。
作为一种可能的实现方式，如果上述系统负载大于等于第一预设阈值，则接入网设备确定寻呼信息的发送位置为第三寻呼周期组中的位置。
在该可能的实现方式中，上述第三寻呼周期组包括一个寻呼周期。

以下结合图1所示的移动通信系统架构，以NR移动通信系统为例，对寻呼进行说明和介绍：
寻呼(paging)用于通知终端设备建立业务；或者，用于通知终端设备小区系统信息发生改变，以使终端设备重新读取改变后的系统广播消息；或者，用于通知终端设备接收ETWS信息。其中，当用于通知终端设备建立业务时，例如可以通知空闲态(idle)的终端设备或者inactive状态的终端设备。空闲态的终端设备是指驻留在无线接入网设备下的小区、但未与无线接入网设备建立连接的终端设备。inactive状态的终端设备是指保持与核心网设备的连接但是并未进入激活态的终端设备。
寻呼过程通过核心网设备、无线接入网设备以及终端设备交互完成，无线接入网设备接收到核心网设备的寻呼消息后，基于寻呼参数和终端设备标识，使用预设的计算方式确定出下发该寻呼消息的寻呼时机，并在该寻呼时机上扫描全部波束发送寻呼消息。终端设备按照与无线接入网相同的寻呼参数、终端设备标识以及相同的计算方式确定接收寻呼消息的寻呼时机，并在该寻呼时机的某个波束上接收寻呼消息。对于无线接入网设备和终端设备来说，在确定寻呼消息发送或接收时机的计算方式中，涉及多个寻呼参数。这些寻呼参数包括但不限于：寻呼周期T、寻呼密度N、每个寻呼帧(paging frame，PF)的寻呼时机(paging occasion，PO)数Ns、同步信号块(synchronization signal block，SSB)波束个 数S。其中，寻呼周期可以是非连接接收(discontinuous reception，DRX)周期。寻呼密度N可以指一个寻呼周期T中的PF的个数。一个PF可以为一个无线帧，或者，一个PF还可以跨无线帧，例如，一个PF可以包括2个无线帧。当PF跨无线帧时，PF的位置表示PF的开始帧的位置。每个PF中可以包括Ns个PO，寻呼消息在这些PO上发送。SSB波束个数可以指在一个PO上发送同一个寻呼消息的波束个数，在这些波束中，每个波束发送的寻呼消息相同，并且，波束的方向各不相同。图2为NR移动通信系统的寻呼参数示例图，如图2所示，在一个寻呼周期T中，可以包括一个偏置PF_offset和N个PF。PF_offset表示寻呼帧的偏移量(也可以称为偏置)，用于调整寻呼帧在寻呼周期中的位置。示例性的，N可以为T内包含的帧个数的一半。一个PF中包括Ns个PO。Ns例如可以为4。若Ns为4，同时假设PF包括2个无线帧，在NR移动通信系统中，一个无线帧可以包括20个时隙，因此，一个PO可以包含10个时隙。每个PO中可以使用S个波束发送寻呼消息。S例如可以为7。如图2所示例的，每个PO的10个时隙中，7个时隙可以被用于下行传输，若S为7，则可以在每个用于下行传输的时隙的特定符号上使用特定方向的波束发送寻呼消息。若图2所示例的，在1号时隙的第4至6个符号使用一个方向的波束发送寻呼消息，在2号时隙的第4至6个符号上使用另一个方向的波束发送寻呼消息，以此类推，从而利用S个波束在不同方向上发送寻呼消息。
值得说明的是，图2所示的寻呼参数的取值仅为一种示例，不应作为对本申请实施例的限制。
以无线接入网设备侧为例，如前文所述，无线接入网设备基于前述的寻呼参数、终端设备标识，使用预设的计算方式确定下发寻呼消息的寻呼时机，以下说明一种可能的计算方式。
首先，无线接入网设备使用下述公式(1)计算寻呼终端设备的PF：
(SFN+PF_offset)mod T＝(T div N)*(UE_ID mod N)          (1)
其中，SFN表示系统帧号(system frame number，SFN)，PF_offset表示寻呼帧的偏移量(也可以称为偏置)，用于调整寻呼帧在寻呼周期中的位置。
T表示前述的寻呼参数中的寻呼周期T，T的取值为系统消息广播的DRX、以及寻呼消息中所指示的DRX中的较小值。
N表示前述的寻呼参数中的寻呼密度N，N＝min(T，nB)。其中，nB表示一个寻呼周期中PF的总数，nB为高层配置参数，无线接入网设备可以通过系统消息将nB广播给终端设备。nB的取值例如可以为4T、2T、T、T/2、T/4、T/8、T/16、T/32等中任一项。
UE_ID表示终端设备的标识，UE_ID＝IMSI mod 1024。IMSI为终端设备的国际移动用户识别码(international mobile subscriber identification number，IMSI)。
div为整除函数。
mod函数为求余函数，(SFN+PF_offset)mod T表示将(SFN+PF_offset)与T作除法运算后的余数。
在通过上述公式(1)得到PF后，无线接入网设备采用下述公式(2)和表1计算具体寻呼终端设备的PO：
i_s＝floor(UE_ID/N)mod Ns        (2)
其中，i_s表示PO的索引，Ns表示前述的寻呼参数中的每个寻呼帧的寻呼时机数Ns， Ns＝max(1,nB/T)，即Ns为1与nB/T中的较大者，floor()为向下取整函数。
通过上述公式(2)计算出i_s后，以PF为基准，按照i_s确定出PO。
在基于上述公式(2)得到PO的基础上，无线接入网设备进一步可以根据前述的寻呼参数中的SSB波束个数S等信息，确定在PO中的哪些符号上使用哪些波束发送寻呼消息。
终端设备侧可以相应使用上述计算方式确定如何接收寻呼消息，不再赘述。
图3为现有技术中一种基于寻呼参数发送寻呼消息的交互流程图，如图3所示，基于寻呼参数发送寻呼消息的过程包括：
S301、无线接入网设备配置寻呼参数。
无线接入设备可以在系统初始化等阶段，通过人工配置方式配置寻呼参数。例如，可以由人工输入每个寻呼参数的值，无线接入网设备保存用户所输入的每个寻呼参数的值。
当寻呼参数配置完成后，无线接入网设备在后续的寻呼过程中，无论系统状态如何变化，均按照已配置的固定的寻呼参数确定发送寻呼消息的时机、波束等。直至寻呼参数再次通过人工配置方式进行调整。
其中，本申请实施例所述无线接入网的系统状态可以指无线接入网的系统负载、寻呼负载等。寻呼负载可以指无线接入网设备设定时间内从核心网设备接收的寻呼消息的峰值。
S302、无线接入网设备通过系统消息块1(system information block1，SIB1)消息将上述寻呼参数广播给终端设备。
相应的，终端设备接收寻呼参数。
S303、终端设备基于寻呼参数以及终端设备的标识，确定出属于自己的PF、PO。
S304、终端设备开启DRX接收方式。
其中，终端设备在每个寻呼周期T中，有且仅有一个PF和PO用于接收寻呼消息。
S305、核心网设备向无线接入网设备发送寻呼消息。
S306、无线接入网设备基于前述步骤S301所配置的寻呼参数、待寻呼的终端设备的标识，使用前述的计算方式，确定出发送寻呼消息的PF和PO。
S307、无线接入网设备在确定出的PO上发送寻呼消息。
通过上述图3所示的流程可以看出，在现有技术中，寻呼参数预先进行配置，配置完成后，无论系统状态如何发生变化，无线接入网设备均按照所配置的寻呼参数确定发送寻呼消息的时机。核心网设备在发送寻呼消息时，需要在跟踪区(tracing area，TA)范围内的所有小区下发，而核心网要下发的寻呼消息的数量巨大，对于无线接入网设备来说，为了保证寻呼消息的正常发送，在配置寻呼参数时，寻呼参数需要配置为满足最大寻呼负载，其中，寻呼负载可以用于指示核心网设备的寻呼消息峰值，由此可能产生如下两个问题。
首先，寻呼时隙开销过大。
在一个PO内，无线接入网将所有的下行时隙用于发送寻呼消息，以前述图2所示的PO为例，一个PO包含10个时隙，其中包括6个下行时隙(downlink slot，图2中使用D表示)，3个上行时隙(uplink slot，图2中使用U表示)，1个特殊时隙(special slot，图2中使用S表示)，S可以作为下行时隙使用，因此，一个PO中可以有7个下行时隙，该7个下行时隙均被用于发送寻呼消息。以上下行帧配比为1:4为例，假设寻呼周期T为128无线帧，寻呼密度N为64，每个PF中PO数Ns为1，SSB波束个数为7为例，则寻呼时隙的数量为7，同时，按照下述公式(3)计算寻呼时隙占用下行时隙的比例(简称寻呼时 隙占比)：
寻呼时隙占比＝N*Ns*S/T周期内下行slot总数        (3)
将上述示例的参数代入上述公式(3)，可以得到在上下行帧配比为1:4、寻呼周期T为128无线帧、寻呼密度N为64、SSB波束个数为7时的寻呼时隙占比为21.88％，由此可知，在所有的下行时隙中，21.88％的时隙被用于发送寻呼消息，寻呼时隙的开销较大。
其次，寻呼能耗开销大。
基于前述的描述，无线接入网基于寻呼参数和终端设备的标识，确定出寻呼时机，相应的，无线接入网设备需要在该确定的寻呼时机上发送寻呼消息，由于寻呼参数预先配置，由此确定的寻呼时机为固定的时机，即使当寻呼负载较小时，这些寻呼时机仍然不能休眠，从而导致无线接入网的寻呼能耗开销大。
基于上述问题，本申请实施例提供了一种通信方法，将至少一个寻呼周期组成一个寻呼周期组，该寻呼周期组中不同的寻呼时机服务于不同的终端设备。无线接入网设备根据核心网设备的寻呼消息峰值以及无线接入网的寻呼能力，动态确定寻呼信息在寻呼周期组中的发送位置，并在该发送位置上发送寻呼信息，从而使得无线接入网设备提供的寻呼时机与系统状态匹配，进而可以在低的寻呼负载时减少寻呼时隙，以降低寻呼时隙以及寻呼能耗的开销。
本申请实施例的方法可以适用于任一移动通信系统，例如LTE通信系统、NR通信系统、未来其他通信系统等。
下述通过一些实施例对本申请实施例提供的通信方法进行详细说明。下面这几个实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
为了便于对本申请实施例的描述，下述申请文件以NR系统为例，对本申请实施例进行说明和介绍。
图4为本申请实施例提供的一种通信方法的流程示意图。本实施例涉及无线接入网设备基于第一信息和第二信息动态确定寻呼信息在寻呼周期组中的给我的过程。如图4所示，该方法包括：
S401、无线接入网设备根据第一信息和第二信息，确定寻呼周期组包含的寻呼周期数量以及寻呼信息在寻呼周期组中的发送位置，该寻呼周期组中包括至少一个寻呼周期，并且，该寻呼周期组中不同寻呼时机服务于不同终端设备。
其中，上述第一信息用于指示设定时间内来自核心网设备的寻呼消息以及无线接入网设备产生的寻呼消息的峰值。
可选的，无线接入网设备可以按照设定的周期执行本步骤，示例性的，无线接入网设备可以每间隔5分钟执行本步骤，则设定的周期为5分钟，相应的，上述的设定时间为5分钟。在每个设定的周期内，无线接入网设备持续监测核心网设备在每个单位时间向无线接入网设备发送的寻呼消息数量，以及无线接入网设备自身所产生的寻呼消息数量，该单位时间例如可以为秒等。当设定的周期结束时，获取单位时间中寻呼消息数量之和的最大值，并将该最大值作为当前周期的寻呼消息峰值。其中，上述寻呼消息数量之和是指单位时间中来自核心网设备的寻呼消息数量以及无线接入网设备自身产生的寻呼数量之和。通过该寻呼消息峰值，能够获知无线接入网设备可能需要处理的最大寻呼数量。该寻呼消息峰值也可以称为无线接入网设备在当前周期内的寻呼负载。
上述第二信息用于指示无线接入网设备的寻呼能力。
可选的，上述寻呼能力可以指无线接入网设备在单位时间内能够承载对其的寻呼的终端设备的数量，该单位例如可以为秒等。应理解，此处的单位时间与上述的监测核心网设备发送的寻呼消息数量的单位时间可以相同，也可以不同，本申请实施例对此不做限定。
一种示例中，无线接入网设备可以通过如下公式(4)计算无线接入网设备的寻呼能力。
X＝N*Ns*M/T           (4)
其中，X表示寻呼能力，N表示寻呼密度N，Ns表示每个PS中的PO数量Ns，M表示一条寻呼消息可以同时寻呼多终端设备的个数，T表示寻呼周期T。
示例性的，上述M可以为32，即无线接入网设备可以通过一条寻呼消息同时寻呼32个终端设备。
由上述可知，由上述第一信息所指示的设定时间内来自核心网设备的寻呼消息以及无线接入网设备产生的寻呼消息的峰值能够体现需要无线接入网设备处理的寻呼消息数量，即无线接入网设备的寻呼负载，由上述第二信息所指示的寻呼能力能够体现接入网设备在单位时间内能够处理的寻呼消息数量。基于这两种信息，无线接入网设备可以确定寻呼周期组包含的寻呼周期数量以及寻呼信息在寻呼周期组中的发送位置。寻呼周期组中包括至少一个寻呼周期，同时，寻呼周期组中不同寻呼时机服务于不同终端设备，即，一个终端设备在一个寻呼周期组中仅能使用一个寻呼时机。为便于描述，本申请实施例将寻呼周期组所包含的寻呼周期的数量称为寻呼周期组的长度。当寻呼负载较小时，可以将寻呼周期组的长度调整为小于当前的长度，同时，对于一个终端设备来说，在调整后的寻呼周期组中仍然仅占用一个寻呼时机，因此，能够使得无线接入网设备用于寻呼的时机密度变小，进而使得寻呼时机与系统状态匹配，可以在低的寻呼负载时减少寻呼时隙，以降低寻呼时隙以及寻呼能耗的开销。
应理解，上述寻呼信息可以指无线接入网设备可能从核心网设备接收到的用于寻呼各个终端设备的信息。该寻呼信息并非指针对某一个特定终端设备的寻呼信息。该寻呼信息可以通过例如寻呼消息来携带或表示。
可选的，上述寻呼周期组中的发送位置，可以指寻呼周期组中可以用于承载寻呼信息的所有位置，而并非其中一个或一部分位置。
S402、无线接入网设备在上述发送位置发送寻呼信息。
可选的，当无线接入网设备接收到核心网设备发送的寻呼信息后，按照前述公式(1)-公式(2)所示的方法，确定出发送该寻呼信息的寻呼时机，进而，基于上述步骤S401所确定出寻呼周期组中的发送位置，并在这些发送位置中的上述的寻呼时机上发送该寻呼信息。而对于终端设备来说，仍然按照前述公式(1)-公式(2)的方式计算寻呼信息的接收时机，并在这些时机上监听和接收寻呼消息，因此，无线接入网设备的上述处理过程对于终端设备来说是无感知的。
应理解，上述步骤S402执行时依赖于上述步骤S401所得到的发送位置，但是步骤S402并不一定是在S401之后立即执行。无线接入网设备可以按照一定的周期，或者在特定的事件触发下执行步骤S401，以确定上述发送位置，该特定的事件例如可以是上述寻呼消息峰值和/或上述寻呼能力发生变化。上述步骤S402可以在无线接入网设备接收到核心网设 备发送的指示寻呼某个终端设备的消息时执行。
本实施例中，由第一信息所指示的设定时间内来自核心网设备的寻呼消息以及无线接入网设备产生的寻呼消息的峰值能够体现需要无线接入网设备处理的寻呼消息数量，即无线接入网设备的寻呼负载，由第二信息所指示的寻呼能力能够体现接入网设备在单位时间内能够处理的寻呼消息数量。该两种信息能够体现无线接入网的系统状态。同时，无线接入网设备将至少一个寻呼周期组成一个寻呼周期组，该寻呼周期组中不同的寻呼时机服务于不同的终端设备。在不同的系统状态下，寻呼周期组所包含的寻呼周期的数量可以不同。无线接入网设备可以根据第一信息和第二信息所表示的系统状态确定寻呼周期组的长度以及寻呼信息在该寻呼周期组中的发送位置。当寻呼负载较小时，无线接入网设备可以将寻呼周期组的长度调整为大于当前的长度，同时，对于一个终端设备来说，在调整后的寻呼周期组中仍然仅占用一个寻呼时机，因此，能够使得无线接入网设备用于寻呼的密度变小，进而使得寻呼时机与系统状态匹配，可以在低的寻呼负载时减少寻呼时隙，以降低寻呼时隙以及寻呼能耗的开销。可选的，按照上述实现方式，也可以不需要通知终端设备该无线接入网设备最后确定出的该发送位置，终端设备可以根据最初该无线接入网设备下发的寻呼参数就可以实现被寻呼(例如可以参照S301-S304)，从而可以节省信令开销。
在上述步骤S401中确定寻呼信息在寻呼周期组中的发送位置时，可以使用如下方式中的任意一种确定。
第一种可选方式中，无线接入网设备可以仅根据上述第一信息和第二信息确定寻呼周期组包含的寻呼周期数量以及寻呼信息在该寻呼周期组中的发送位置。
在该可选方式中，无线接入网设备不考虑其他因素，仅根据上述第一信息和第二信息确定寻呼周期组包含的寻呼周期数量以及寻呼信息在该寻呼周期组中的发送位置。
这种方式能够基于第一信息和第二信息，快速确定出寻呼周期组包含的寻呼周期数量以及寻呼信息在该寻呼周期组中的发送位置。
第二种可选方式中，无线接入网设备可以根据上述第一信息和第二信息，以及第三信息确定寻呼周期组包含的寻呼周期数量以及寻呼信息在该寻呼周期组中的发送位置。
其中，上述第三信息用于指示无线接入网设备的系统负载。
一种示例中，无线接入网设备的系统负载可以指无线接入网设备中的资源块(resource block，RB)占用数量、占用率等。另一些示例中，上述系统负载还可以指无线接入网设备的CPU占用率、内存占用率等。
在该可选方式中，无线接入网设备可以在前述监测核心网设备的寻呼消息数量的同时，持续监测无线接入网设备的系统负载。该系统负载可以指在前述的设定时间内，即每个周期内，无线接入网设备在单位时间的系统负载的峰值。该单位时间可以与监测核心网设备的寻呼消息数量的单位时间相同。
在该可选方式中，无线接入网设备根据第一信息、第二信息和第三信息确定寻呼周期组包含的寻呼周期数量以及寻呼信息在该寻呼周期组中的发送位置时，可以按照如下方式处理：
若上述的系统负载小于第一预设阈值，则无线接入网设备根据第一信息和第二信息确定寻呼周期组包含的寻呼周期数量以及寻呼信息在该寻呼周期组中的发送位置。
其中，如果系统负载小于上述第一预设阈值，则说明无线接入网设备当前的系统负载 较小，在这种情况下，无线接入网设备才根据第一信息和第二信息重新确定寻呼周期组包含的寻呼周期数量以及寻呼信息在该寻呼周期组中的发送位置，进而可以在寻呼负载较小时降低寻呼时隙和寻呼能力。而当无线接入网设备当前的系统负载已经较大，此时，即使寻呼负载较小并减小了寻呼时隙的占用，原来的寻呼时隙也可能被用于数据传输，以支撑较大的系统负载，而系统能耗并不能得到降低。因此，无线接入网设备仅在系统负载小于第一预设阈值时，才根据第一信息和第二信息重新确定寻呼周期组包含的寻呼周期数量以及寻呼信息在该寻呼周期组中的发送位置，从而确定出与系统负载和寻呼负载匹配的寻呼周期组，以使得寻呼周期组长度的调整能够真正降低寻呼时隙和寻呼能耗的开销。
以系统负载为RB占用率为例，判断系统负载是否小于上述第一预设阈值的一种示例性过程包括：
1、计算每个无线帧的RB数量，记为totalRbNum。
2、计算包括寻呼消息在内的每个无线帧发送公共消息时间窗内的RB数量，记为usedRbNum。
3、计算usedRbNum与totalRbNum的比值，将结果记为usedRbRate_acceptable。
4、计算无线接入网设备统计的实际RB占用率(记为usedRbRate_cur)与上述usedRbRate_acceptable的差值，当差值小于第一预设阈值时，说明无线接入网设备当前的系统负载较小，可以继续根据第一信息和第二信息确定寻呼参数的值。
以下说明在上述两种可选方式中，根据第一信息和第二信息，确定寻呼周期组包含的寻呼周期数量以及寻呼信息在该寻呼周期组中的发送位置的具体过程。
第一种可选方式中，如果无线接入网设备判断出上述寻呼消息峰值与上述寻呼能力的比值小于第二预设阈值，则无线接入网设备确定寻呼信息的发送位置为第一寻呼周期组中的位置。
可选的，上述第一寻呼周期组所包括的寻呼周期数量大于无线接入网设备当前使用的寻呼周期组所包括的寻呼周期数量。
如前文所述，上述寻呼消息峰值指核心网设备向无线接入网设备发送的寻呼消息的峰值，上述寻呼能力指无线接入网设备在单位时间内能够承载对其的寻呼的终端设备的数量，上述寻呼消息峰值与上述寻呼能力的比值，可以表征无线接入网设备用于寻呼的负载状态。该负载状态可以体现系统状态。作为一种示例，本申请实施例可以将用于寻呼的负载状态划分为常规态、轻载态和空载态。每种状态分别对应上述比值的一个比值范围。应理解，轻载态对应范围内的比值均小于常规态对应范围内的比值，空载态对应范围内的比值均小于轻载态对应范围内的比值。
可选的，不同的负载状态之间可以分别对应一个第二预设阈值。示例性的，常规态进入轻载态时，对应一个第二预设阈值，轻载态进入空载态时，对应另一个第二预设阈值。
当无线接入网设备判断出上述寻呼消息峰值与上述寻呼能力的比值小于第二预设阈值，表示无线接入网设备处于该第二预设阈值对应的负载状态下。值得说明的是，本申请实施例所述的处于该第二预设阈值对应的负载状态下，可以指负载状态从先前的状态变化至该负载状态。当负载状态变化至该负载状态时，无线接入网设备确定寻呼信息的发送位置为第一寻呼周期组中的位置，并且，第一寻呼周期组所包括的寻呼周期数量大于无线接入网设备当前使用的寻呼周期组所包括的寻呼周期数量。即，相对于当前正在使用的寻呼 周期组来说，新确定的第一寻呼周期组的长度大于当前正在使用的寻呼周期组的长度。因此，在负载状态较轻时，将寻呼周期组的长度增大，从而使得无线接入网设备用于寻呼的时机密度变小，以降低寻呼时隙和寻呼能耗的开销。
示例性的，假设无线接入网设备当前处于常规态，当前使用的寻呼周期组的长度为7，当判断出上述寻呼消息峰值与上述寻呼能力的比值小于一个第二预设阈值，无线接入网设备可以确定使用的第一寻呼周期组的长度为8。假设无线接入网设备当前处于轻载态，当前使用的寻呼周期组的长度为8，当判断出上述寻呼消息峰值与上述寻呼能力的比值小于另一个第二预设阈值，无线接入网设备可以确定使用的第一寻呼周期组的长度为9。在该示例中，从常规态到轻载态，再从轻载态到空载态，可以逐渐增加寻呼周期组的长度，同时，在各寻呼周期组中，不同的寻呼时机服务于不同的终端设备，因此，使得无线接入网设备用于寻呼的时机密度逐渐减小，以同无线接入网设备的系统状态匹配。
当确定负载变化并确定需要使用新的第一寻呼周期组后，可以获知该第一寻呼周期组中可以用于承载寻呼信息的位置，并确定在该位置上发送寻呼信息。
其中，该第一寻呼周期组中可以用于承载寻呼信息的位置可以包括第一寻呼周期组中的至少一个寻呼周期，也可以包括第一寻呼周期组中至少一个寻呼周期中的至少一个寻呼帧，也可以包括第一寻呼周期组中至少一个寻呼周期的至少一个寻呼帧中的至少一个寻呼时机。关于该位置的具体信息将在下述实施例中详细说明。
第二种可选方式中，如果无线接入网设备判断出上述寻呼消息峰值与上述寻呼能力的比值大于第三预设阈值，则无线接入网设备确定寻呼信息的发送位置为第二寻呼周期组中的位置。
可选的，上述第二寻呼周期组所包括的寻呼周期数量小于无线接入网设备当前使用的寻呼周期组所包括的寻呼周期数量。
如前文所述，上述寻呼消息峰值指核心网设备向无线接入网设备发送的寻呼消息的峰值，上述寻呼能力指无线接入网设备在单位时间内能够承载对其的寻呼的终端设备的数量，上述寻呼消息峰值与上述寻呼能力的比值，可以表征无线接入网设备用于寻呼的负载状态。该负载状态可以体现系统状态。作为一种示例，本申请实施例可以将用于寻呼的负载状态划分为常规态、轻载态和空载态。每种状态分别对应上述比值的一个比值范围。应理解，常规态对应范围内的比值均大于轻载态对应范围内的比值，轻载态对应范围内的比值均大于空载态对应范围内的比值。
可选的，不同的负载状态之间可以分别对应一个第三预设阈值。示例性的，空载态进入轻载态时，对应一个第三预设阈值，轻载态进入常规态时，对应另一个第三预设阈值。
当无线接入网设备判断出上述寻呼消息峰值与上述寻呼能力的比值大于第三预设阈值，表示无线接入网设备处于该第三预设阈值对应的负载状态下。值得说明的是，本申请实施例所述的处于该第三预设阈值对应的负载状态下，可以指负载状态从先前的状态变化至该负载状态。当负载状态变化至该负载状态时，无线接入网设备确定寻呼信息的发送位置为第二寻呼周期组中的位置，并且，第二寻呼周期组所包括的寻呼周期数量小于无线接入网设备当前使用的寻呼周期组所包括的寻呼周期数量。即，相对于当前正在使用的寻呼周期组来说，新确定的第二寻呼周期组的长度小于当前正在使用的寻呼周期组的长度。因此，在负载状态较重时，将寻呼周期组的长度减小，从而使得无线接入网设备用于寻呼的 时机密度变大，以保证寻呼信息可以及时发送，不会产生延迟。
示例性的，假设无线接入网设备当前处于空载态，当前使用的寻呼周期组的长度为9，当判断出上述寻呼消息峰值与上述寻呼能力的比值大于一个第三预设阈值，无线接入网设备可以确定使用的第二寻呼周期组的长度为8。假设无线接入网设备当前处于轻载态，当前使用的寻呼周期组的长度为8，当判断出上述寻呼消息峰值与上述寻呼能力的比值大于另一个第三预设阈值，无线接入网设备可以确定使用的第二寻呼周期组的长度为7。在该示例中，从空载态到轻载态，再从轻载态到常规态，可以逐渐减小寻呼周期组的长度，同时，在各寻呼周期组中，不同的寻呼时机服务于不同的终端设备，因此，使得无线接入网设备用于寻呼的时机密度逐渐增大，以同无线接入网设备的系统状态匹配。
当确定负载变化并确定需要使用新的第二寻呼周期组后，可以获知该第二寻呼周期组中可以用于承载寻呼信息的位置，并确定在该位置上发送寻呼信息。
其中，该第二寻呼周期组中可以用于承载寻呼信息的位置可以包括第一寻呼周期组中的至少一个寻呼周期，也可以包括第一寻呼周期组中至少一个寻呼周期中的至少一个寻呼帧，也可以包括第一寻呼周期组中至少一个寻呼周期的至少一个寻呼帧中的至少一个寻呼时机。关于该位置的具体信息将在下述实施例中详细说明。
以下对第一寻呼周期组和第二寻呼周期组中可以用于承载寻呼信息的位置进行说明。
为便于描述，以下将第一寻呼周期组中可以用于承载寻呼信息的位置称为第一寻呼周期组的寻呼位置，将第二寻呼周期组中可以用于承载寻呼信息的位置称为第二寻呼周期组的寻呼位置。
如前文所述，第一寻呼周期组的寻呼位置可以包括第一寻呼周期组中的至少一个寻呼周期，也可以包括第一寻呼周期组中至少一个寻呼周期中的至少一个寻呼帧，也可以包括第一寻呼周期组中至少一个寻呼周期的至少一个寻呼帧中的至少一个寻呼时机。第二寻呼周期组的寻呼位置可以包括第一寻呼周期组中的至少一个寻呼周期，也可以包括第一寻呼周期组中至少一个寻呼周期中的至少一个寻呼帧，也可以包括第一寻呼周期组中至少一个寻呼周期的至少一个寻呼帧中的至少一个寻呼时机。
以第一寻呼周期组为例，上述三种寻呼位置的含义如下：
1、至少一个寻呼周期
寻呼位置包括第一寻呼周期组中的至少一个寻呼周期，是指寻呼信息仅在第一寻呼周期组中的该至少一个寻呼周期内发送，该至少一个寻呼周期可以称为第一寻呼周期组的寻呼激活期，第一寻呼周期组中除该至少一个寻呼周期外的其他寻呼周期可以称为第一寻呼周期组的寻呼休眠期。如果无线接入网设备在寻呼休眠期从核心网接收到寻呼信息，则进行缓存，当处于寻呼激活期时，再将缓存的寻呼信息承载在该至少一个寻呼周期的寻呼时机中进行发送。
该方式是将寻呼信息汇聚至第一寻呼周期组的至少一个寻呼周期上发送，可以称为寻呼周期间汇聚。应理解，该至少一个寻呼周期所能够提供的寻呼时机应能够满足不使用该汇聚方式时一个寻呼周期所能够提供的寻呼时机。
2、至少一个寻呼周期中的至少一个寻呼帧
寻呼位置包括第一寻呼周期组中的至少一个寻呼周期中的至少一个寻呼帧，是指寻呼信息仅在第一寻呼周期组的至少一个寻呼周期的该至少一个寻呼帧上发送，至少一个寻呼 周期的该至少一个寻呼帧可以称为该寻呼周期的寻呼激活期，第一寻呼周期组中除该至少一个寻呼周期中该至少一个寻呼帧外的其他寻呼帧可以称为寻呼休眠期。
作为一种示例，寻呼位置可以包括第一寻呼周期组中每个寻呼周期中的至少一个寻呼帧，则，每个寻呼周期中的该至少一个寻呼帧为寻呼激活期，第一寻呼周期组中各寻呼周期中除该至少一个寻呼帧外的其他寻呼帧为寻呼休眠期。
如果无线接入网设备在寻呼休眠期从核心网接收到寻呼信息，则进行缓存，当处于寻呼激活期时，再将缓存的寻呼信息承载在该至少一个寻呼帧的寻呼时机中进行发送。
该方式是将寻呼信息汇聚至第一寻呼周期组的至少一个寻呼周期的至少一个寻呼帧上发送，可以称为寻呼帧间汇聚。应理解，至少一个寻呼周期的至少一个寻呼帧所能够提供的总的寻呼时机应能够满足不使用该汇聚方式时一个寻呼周期所能够提供的寻呼时机。
3、至少一个寻呼周期的至少一个寻呼帧中的至少一个寻呼时机
寻呼位置包括第一寻呼周期组中的至少一个寻呼周期的至少一个寻呼帧中的至少一个寻呼时机，是指寻呼信息仅在第一寻呼周期组的至少一个寻呼周期的至少一个寻呼帧的至少一个寻呼时机上发送，至少一个寻呼帧的该至少一个寻呼时机可以称为该寻呼帧的寻呼激活期，第一寻呼周期组中除该至少一个寻呼周期的至少一个寻呼帧的至少一个寻呼时机外的其他寻呼时机可以称为寻呼休眠期。
作为一种示例，寻呼位置可以包括第一寻呼周期组中每个寻呼周期中的每个寻呼帧中的至少一个寻呼时机，则，每个寻呼周期中的每个寻呼帧中的该至少一个寻呼时机为寻呼激活期，第一寻呼周期组中各寻呼周期的各寻呼帧中除该至少一个寻呼时机外的其他寻呼时机为寻呼休眠期。
如果无线接入网设备在寻呼休眠期从核心网接收到寻呼信息，则进行缓存，当处于寻呼激活期时，再将缓存的寻呼信息承载在该至少一个寻呼时机中进行发送。
该方式是将寻呼信息汇聚至第一寻呼周期组的至少一个寻呼周期的至少一个寻呼帧的至少一个时机上发送，可以称为寻呼时机间汇聚。应理解，至少一个寻呼周期的至少一个寻呼帧的至少一个寻呼时机所能够提供的总的寻呼时机应能够满足不使用该汇聚方式时一个寻呼周期所能够提供的寻呼时机。
第二寻呼周期组的三种寻呼位置的含义与上述第一寻呼组的三种寻呼位置的含义相同，不再赘述。
具体实施过程中，对于第一寻呼周期组，该第一寻呼周期组的寻呼位置可以是上述至少一个寻呼周期、至少一个寻呼帧和至少一个寻呼时机中的一种，也可以是该三种位置中的其中两种或三种的结合。
对于第二寻呼周期组，该第二寻呼周期组的寻呼位置可以是上述至少一个寻呼周期、至少一个寻呼帧和至少一个寻呼时机中的一种，也可以是该三种位置中的其中两种或三种的结合。
可选的，无线接入网设备可以通过配置参数配置第一寻呼周期组和第二寻呼周期组可以用于承载寻呼信息的位置。每个配置参数对应于一种配置方式。示例性的，配置参数1表示第一寻呼周期组或第二寻呼周期组的寻呼位置为上述的至少一个寻呼周期，配置参数2表示第一寻呼周期组或第二寻呼周期组的寻呼位置为上述的至少一个寻呼帧，配置参数3表示第一寻呼周期组或第二寻呼周期组的寻呼位置为上述的至少一个寻呼时机，配置参 数4表示第一寻呼周期组或第二寻呼周期组的寻呼位置为上述至少一个寻呼周期和至少一个寻呼帧结合所得到的位置。
可选的，上述第一寻呼周期组和上述第二寻呼周期组可以使用相同的配置方式，也可以使用不同的配置方式。
一种示例中，第一寻呼周期组和第二寻呼周期组使用相同的配置方式，均按照配置参数1进行配置，则第一寻呼周期组的寻呼位置和第二寻呼周期组的寻呼位置均为上述的至少一个寻呼周期。
另一种示例中，第一寻呼周期组和第二寻呼周期组使用不同的配置方式，第一寻呼周期组按照配置参数1进行配置，则第一寻呼周期组的寻呼位置为上述的至少一个寻呼周期，第二寻呼周期组按照配置参数2进行配置，则第二寻呼周期组的寻呼位置为上述的至少一个寻呼帧。
以下分别给出上述三种寻呼位置及其进行结合的示例。为便于描述，以下示例均以第一寻呼周期为例进行说明，应理解，第二寻呼周期同样也可以应用如下的示例。
图5为寻呼位置为第一寻呼周期组中的至少一个寻呼周期的示例，如图5所示，上半部分为现有技术中未使用汇聚方式的寻呼位置，下半部分为使用本申请实施例的汇聚方式的寻呼位置，以下的描述均是对使用汇聚方式的寻呼位置的描述，下述的图6和图7的描述也是针对汇聚方式的寻呼位置的描述，不再赘述。第一寻呼周期组的长度为n，即第一寻呼周期组中包括n个寻呼周期，n为大于0的整数。该第一寻呼周期组中，仅第n个寻呼周期为寻呼激活期，其余的第1至第n-1个寻呼周期为寻呼休眠期。无线接入网设备在寻呼休眠期接收到寻呼信息后，将寻呼信息缓存，到达寻呼激活期后，无线接入网设备可以按照上述公式(1)-公式(2)所示的方法，确定出发送每个寻呼信息的寻呼时机，并在该第n个寻呼周期的该寻呼时机上发送每个寻呼信息，从而实现将寻呼信息汇聚在第一寻呼周期组的最后一个寻呼周期发送。应理解，该寻呼激活期，即第n个寻呼周期所能够提供的寻呼时机，应能够满足上述图2所示的按照寻呼周期T、寻呼密度N和寻呼时机数所得到的寻呼时机，以保证无线接入网设备能够正常将核心网设备发送的寻呼信息发送至终端设备。示例性的，该第n个寻呼周期的寻呼时机与上述图2所示的按照寻呼周期T、寻呼密度N和寻呼时机数所得到的寻呼时机相同。
图6为寻呼位置为第一寻呼周期组中的至少一个寻呼周期的至少一个寻呼帧的示例，如图6所示，第一寻呼周期组的长度为n，即第一寻呼周期组中包括n个寻呼周期，n为大于0的整数。该第一寻呼周期组中，每个寻呼周期中选择1/n时间窗作为寻呼激活期，1/n时间窗为一个寻呼帧，该每个寻呼周期中的其余(n-1)/n时间窗作为寻呼休眠期。如图6所示例的，选择第1个寻呼周期中的第1个寻呼帧作为寻呼激活期，第2个寻呼周期组中的第2个寻呼帧作为寻呼激活期，以此类推。
无线接入网设备在寻呼休眠期接收到寻呼信息后，将寻呼信息缓存，到达寻呼激活期后，无线接入网设备可以按照上述公式(1)-公式(2)所示的方法，确定出发送每个寻呼信息的寻呼时机，并在该1/n个时间窗对应的寻呼帧的该寻呼时机上发送寻呼信息，从而实现将寻呼信息汇聚在第一寻呼周期组的部分寻呼帧上发送。应理解，各寻呼激活期所能够提供的总的寻呼时机，应能够满足上述图2所示的按照寻呼周期T、寻呼密度N和寻呼时机数所得到的寻呼时机，以保证无线接入网设备能够正常将核心网设备发送的寻呼信息 发送至终端设备。如图6所示，选择第1个寻呼周期中的第1个寻呼帧作为寻呼激活期，第2个寻呼周期组中的第2个寻呼帧作为寻呼激活期，依次类推，从而使得第一寻呼周期组的寻呼位置可以覆盖上述图2所要求的寻呼时机。
图7为寻呼位置为第一寻呼周期组中的至少一个寻呼周期的至少一个寻呼帧的至少一个寻呼时机的示例，如图7所示，第一寻呼周期组的长度为ns，即第一寻呼周期组中包括ns个寻呼周期，ns为大于0的整数(图7中以4进行示例)，每个寻呼周期包括N个寻呼帧，N为大于0的整数。该第一寻呼周期组中，每个寻呼周期的每个寻呼帧中选择1/ns个时间窗作为寻呼激活期，1/ns时间窗为一个寻呼时机，该每个寻呼周期的每个寻呼帧中的其余(ns-1)/ns时间窗作为寻呼休眠期。如图7所示例的，选择第1个寻呼周期中的每个寻呼帧中的第一个寻呼时机作为寻呼激活期，第2个寻呼周期组中每个寻呼帧中的第2个寻呼时机作为寻呼激活期，以此类推。
无线接入网设备在寻呼休眠期接收到寻呼信息后，将寻呼信息缓存，到达寻呼激活期后，无线接入网设备可以按照上述公式(1)-公式(2)所示的方法，确定出发送每个寻呼信息的寻呼时机，并在该1/ns个时间窗对应的寻呼时机上发送寻呼信息，从而实现将寻呼信息汇聚在第一寻呼周期组的部分寻呼时机上发送。应理解，各寻呼激活期所能够提供的总的寻呼时机，应能够满足上述图2所示的按照寻呼周期T、寻呼密度N和寻呼时机数所得到的寻呼时机，以保证无线接入网设备能够正常将核心网设备发送的寻呼信息发送至终端设备。如图7所示，选择第1个寻呼周期中每个寻呼帧的第1个寻呼时机作为寻呼激活期，第2个寻呼周期组中的每个寻呼帧的第2个寻呼时机作为寻呼激活期，依次类推，从而使得第一寻呼周期组的寻呼位置可以覆盖上述图2所要求的寻呼时机。
除了可以按照上述图5-图7所示例的任意一种方式作为寻呼位置外，还可以使用其结合作为寻呼位置。
一种示例中，可以将前述的寻呼周期间汇聚与寻呼帧间汇聚结合。例如，第一寻呼周期组的长度为S，则可以选择其中的2/S个寻呼周期，在该2/S个寻呼周期中，各选择2个的寻呼帧作为寻呼激活期，同时，各寻呼周期中作为寻呼激活器的寻呼帧可以不同，以使得第一寻呼周期组的寻呼位置可以覆盖上述图2所要求的寻呼时机。
