Description

寻呼方法、基站及用户设备
本申请要求在2018年04月04日提交中国专利局、申请号为201810299228.3的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及物联网(Internet of Things，IoT)技术，例如一种寻呼方法、基站及用户设备。
背景技术
在无线通讯领域，针对不同通讯需求引入了不同的无线接入技术，例如在物联网(Internet of Things，IoT)领域，基于长期演进(Long Term Evolution，LTE：是由第三代合作伙伴计划(The 3rd Generation Partnership Project，3GPP)组织制定的通用移动通信系统(Universal Mobile Telecommunications System，UMTS)技术标准的长期演进)无线接入制式针对IoT需求进行演进，引入了窄带物联网(NarrowBand Internet of Things，NB-IoT)技术和增强的机器类型通信(enhanced Machine Type Communication，eMTC)技术。NB-IoT和eMTC都属于3GPP标准内的低功耗广域网((Low Power Wide Area Network，LPWAN)技术。覆盖增强(Coverage enhancement，CE)和低功耗是NB-IoT和eMTC的两个重要特性。
在目前NB-IoT协议中，寻呼是通过窄带物理下行链路控制信道(Narrowband Physical Downlink Control CHannel，NPDCCH)调度的；为了增强小区及寻呼的覆盖范围，调度寻呼的NPDCCH会重复发送，覆盖范围越大需要的重复次数越多(重复次数越多消耗的下行NPDCCH资源也越多)，且重复次数是通过系统信息块(System Information Block，SIB)广播给用户设备(User Equipment，UE)。
在目前eMTC协议中，覆盖增强包含Mode A和Mode B两种模式；eMTC终端包含两种类型：一种叫低带宽低复杂度终端(Bandwidth reduced low complexity UEs，BL UEs)，其支持Mode A传输模式是必选项；另外一种叫做处于覆盖强增模式下的终端(UEs in CE)，其可以同时支持Mode A和Mode B两种传输模式。BL UEs与UE in CE的寻呼机制是一样的，寻呼都是通过MTC物理下行链路控制信道(机器类型通信(Machine Type Communication，MTC) Physical Downlink Control CHannel，MPDCCH)调度的；为了增强小区及寻呼的覆盖范围，调度寻呼的MPDCCH会重复发送，覆盖范围越大需要的重复次数越多(重复次数越多消耗的下行MPDCCH资源也越多)，且重复次数是通过SIB广播给UE。
另外，无论是NB-IoT还是eMTC，为了降低UE监控寻呼时的功率消耗，都引入了唤醒信号Wakeup Signal，在覆盖增强场景也需要通过重复发送Wakeup Signal来提高覆盖范围，覆盖范围越大需要的重复次数越多(重复次数越多消耗的下行Wakeup Signal资源也越多)。
而目前的相关协议中，调度寻呼的PDCCH的最大重复次数和调度寻呼的Wakeup Signal的最大重复次数都是按照小区覆盖的最大范围来配置的。这样，对于一个小区内覆盖范围较小的UE来说，使用过大的重复次数，不仅会浪费下行资源，也会加大UE监控寻呼过程中的功率消耗。
此外，NB-IoT UE和eMTC UE都存在低能耗的要求，节能需求也比较高，现有技术也没有提供非常有效地改善UE寻呼过程中的节能方案。

具体实施方式
下文中将结合附图对本申请的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出和描述中的至少之一的步骤。
基于LTE无线接入制式针对IoT需求进行演进，引入了NB-IoT技术和eMTC技术。NB-IoT和eMTC都采用了覆盖增加和低功率技术，并且在目前eMTC协议中，覆盖增强功能包含Mode A和Mode B两种模式。但是在寻呼过程中，为了增强小区及寻呼的覆盖范围，调度寻呼的PDCCH会重复发送，覆盖范围越大需要的重复次数越多(重复次数越多消耗的下行PDCCH资源也越多)，且重复次数是通过SIB广播给UE。另外，无论是NB-IoT还是eMTC，为了降低UE 监控寻呼时的功率消耗，都引入了唤醒信号(Wakeup Signal)，在覆盖增强场景也需要通过重复发送唤醒信号来提高覆盖范围，覆盖范围越大需要的重复次数越多(重复次数越多消耗的下行唤醒信号资源也越多)。而目前的相关协议中，调度寻呼的PDCCH的最大重复次数和调度寻呼的唤醒信号的最大重复次数都是按照小区覆盖的最大范围来配置的。这样，对于覆盖范围较小的UE来说(比如覆盖增强受限终端Enhanced Coverage Restricted UE，覆盖增强模式B受限终端CE-ModeB Restricted UE，低发射功率UE)，使用过大的重复次数，不仅会浪费下行资源，也会加大UE寻呼监控过程中的功率消耗。此外，NB-IoT终端和eMTC终端都有低能耗的要求，而低功率发射功率UE的电量一般也低，节能需求也比较高；针对此类节能也需要给UE配置特殊的寻呼参数(比如：寻呼周期、所述寻呼周期内的寻呼资源个数、以及寻呼载波或窄带等)从而减少下行资源的浪费，且有针对性地改善UE监控寻呼过程的节能效果。
针对上述相关技术中存在的问题，本申请实施例提出了一种寻呼方法、基站和用户设备，基于UE类别配置寻呼参数；所述寻呼参数包括如下至少之一：调度寻呼的配置信息和承载寻呼的下行载波信息。如此，对于不同的UE类别配置不同的寻呼参数，即合理配置调度寻呼的配置信息和承载寻呼的下行载波信息中的至少之一，减少了下行资源的浪费，也可以降低UE寻呼监控过程中的功率消耗，提升节能效果。
实施例一
图1为本申请实施例一提供的寻呼方法的流程示意图。如图1所示，该方法，包括：步骤101。
在步骤101中，基站基于用户设备UE类别配置寻呼参数。
所述寻呼参数包括如下至少之一：调度寻呼的配置信息和承载寻呼的下行载波信息。

UE类别影响UE的覆盖范围大小，不同的UE类别的UE具有不同的覆盖范围大小。一般情况下：覆盖增强受限UE的覆盖范围<覆盖增强模式B受限UE的覆盖范围<低功率级别UE的覆盖范围<Legacy UE的覆盖范围。覆盖增强功能受限UE是指不允许使用覆盖增强功能的UE，覆盖增强模式B受限UE是指即不允许使用覆盖增强模式B的UE，所述低功率级别UE是指NB-IoT/eMTC系统中引入的上行最大发射功率为14dBm的UE，或者后续引入的最大发射功率低于一定功率阈值的UE或者其他通过重复发送来增强无线覆盖的无线制式中上行最大发射功率低于一定功率阈值的UE。其他具有限制UE覆盖范围特性UE是指除覆盖增强功能受限UE、覆盖增强模式B受限UE、低功率级别UE之外的覆盖范围受限制的UE，所述Legacy UE是指覆盖范围不受限制，可以按照小区最大覆盖范围配置寻呼参数以及寻呼参数的选择策略的UE。所述移动受限UE为移动速度和移动范围中至少之一受限的UE，比如不移动的UE(也即：静止UE)和间歇性移动的UE。目前相关标准中，最多可以设置3种或者4种覆盖增强级别，不同的覆盖增强级别对应不同的覆盖范围大小即不同的覆盖程度区域。
其中，所述调度寻呼的配置信息包括如下至少之一：调度寻呼的物理下行链路控制信道PDCCH的最大重复次数、调度寻呼的唤醒信号的最大重复次数、调度寻呼的唤醒信号时频位置、寻呼周期、以及所述寻呼周期内的寻呼资源个数nB。
其中，所述承载寻呼的下行载波信息包括如下至少之一：可承载寻呼的载波列表、可承载寻呼的窄带列表、寻呼载波的UE选择权重、寻呼窄带的UE选择权重、寻呼载波的个数、以及寻呼窄带的个数。

其中，在所述基站基于UE类别配置寻呼参数之后，该方法还包括：
所述基站通过系统信息块SIB将基于UE类别配置的寻呼参数发送给UE。
例如基站可以通过SIB将基于UE类别配置的寻呼参数及其对应关系广播给UE。

策略二：从已配置有对应的寻呼参数的所述待寻呼UE的类别中，基于PDCCH或唤醒信号的最大重复次数最小的UE类别对应的寻呼参数选择所述寻呼资源。
其中，在所述基站基于待寻呼UE的类别和配置的寻呼参数选择对应的寻呼资源之前，该方法还包括：所述基站基于移动管理单元MME发送的寻呼消息中携带的所述待寻呼UE的UE类别信息识别所述待寻呼UE的UE类别；所述UE类别信息包括以下至少之一：UE功率级别信息和UE类别指示信息。
其中，所述UE功率级别信息包括UE最大发射功率信息。UE类别指示信息包括所述待寻呼UE的UE类别，所述UE类别包括如下至少之一：覆盖增强功能受限的UE、覆盖增强模式B受限的UE、低功率级别的UE、移动受限UE、处于特定覆盖增强级别的UE、以及其他具有限制UE覆盖范围特性的UE。
例如，当MME向待寻呼UE发起寻呼时，向基站发送的寻呼消息中携带所述待寻呼UE的UE最大发射功率信息或者UE类别指示信息，如此所述基站可以基于所述待寻呼UE的UE最大发射功率信息或者UE类别指示信息识别出所述UE的类别。其中，所述待寻呼UE的UE功率级别信息或者UE类别可以由UE直接上报给MME，或者由UE通过eNB发送给MME。另外所述UE的类别，也可以是UE在MME签约的UE类别。
本实施例一提供的技术方案，基站基于UE类别配置寻呼参数；所述寻呼参数包括如下至少之一：调度寻呼的配置信息和承载寻呼的下行载波信息。如此，对于不同覆盖范围的大小的UE，合理配置寻呼参数，减少下行资源的浪费。
以下通过两个具体示例对实施例一提供的技术方案进行具体描述。
该实施例可以应用于NB-IoT系统或者eMTC，下面提到的基站(eNB)可以是NB-IoT基站或者eMTC基站，下面提到的用户设备UE可以是NB-IoT终端或者eMTC终端，下面提到的PDCCH可以是NPDCCH或者MPDCCH。
示例一：
图2为本申请实施例一示例一提供的寻呼方法的流程示意图。如图2所示，该方法包括：步骤201和步骤202。
在步骤201中，基站eNB基于UE类别配置寻呼参数。
所述寻呼参数包括如下至少之一：调度寻呼的配置信息和承载寻呼的下行 载波信息。
其中，所述UE类别包括如下至少之一：覆盖增强功能受限UE、覆盖增强模式B受限UE、低功率级别UE、移动受限UE、处于特定覆盖增强级别的UE、以及其他具有限制UE覆盖范围特性UE。
其中，所述调度寻呼的配置信息包括如下至少之一：调度寻呼的物理下行链路控制信道PDCCH的最大重复次数、调度寻呼的唤醒信号的最大重复次数、调度寻呼的唤醒信号的时频位置、寻呼周期、以及所述寻呼周期内的寻呼资源个数nB。
其中，所述承载寻呼的下行载波信息包括如下至少之一：可承载寻呼的载波列表、可承载寻呼的窄带列表、寻呼载波的UE选择权重、寻呼窄带的UE选择权重、寻呼载波的个数、以及寻呼窄带的个数。
其中，不同的UE类别对应于不同的覆盖范围。一般而言，覆盖增强受限UE的覆盖范围<覆盖增强模式B受限UE的覆盖范围<低功率级别UE的覆盖范围<Legacy UE的覆盖范围。如此基站可以为不同的UE类别配置不同的调度寻呼的PDCCH的最大重复次数和调度寻呼的唤醒信号的最大重复次数中的至少之一，如此对于覆盖范围受限制的UE不再需要按照小区最大覆盖范围配置调度寻呼的PDCCH的最大重复次数和调度寻呼的唤醒信号的最大重复次数中的至少之一，为覆盖范围越小的UE配置越少的调度寻呼的PDCCH的最大重复次数和调度寻呼的唤醒信号的最大重复次数，从而避免了下行资源的浪费。
另外，覆盖增强功能受限UE的调度寻呼的PDCCH的最大重复次数和调度寻呼的唤醒信号的最大重复次中的至少之一数可以通过标准固定为1(不重复发送)。
同样的，基站也可以为不同的UE类别配置不同的寻呼周期(Paging Cycle)、所述寻呼周期内的寻呼资源个数nB、可承载寻呼载波或窄带列表、寻呼载波或窄带的UE选择权重、寻呼载波或窄带个数等等寻呼参数。例如NB-IoT终端或者eMTC终端都有低功耗、低功率的节能要求，而低功率UE的电量一般也低，节能需求也比较高；针对此类节能也可以基于UE类别配置特殊的寻呼参数，例如为某一UE类别配置特殊的寻呼周期(例如寻呼的DRX周期)、特殊的所述寻呼周期内的寻呼资源个数(nB)、专门的载波、专门的寻呼窄带(paging-narrow Bands)等。
其中，基站可以为所有的UE类别都配置每一个UE类别各自对应的一组寻 呼参数，也可以只为一个或多个UE类别配置各自对应的一组寻呼参数；形成UE类别与寻呼参数对照关系表，保存在本地并广播给所述基站下的所有UE。
在步骤202中，所述基站通过系统信息块SIB将基于UE类别配置的寻呼参数广播给UE。
所述基站在配置完寻呼参数之后，可以通过SIB将配置好的寻呼参数以UE类别与寻呼参数的对应关系广播给归属于该基站下的所有UE。UE收到所述基站基于UE类别配置的寻呼参数后保存在本地。如此，UE和基站都保存了基站基于UE类别配置的寻呼参数。
此外，所述基站还可以包括以下至少之一：基站为特定的UE类别配置特殊的调度寻呼的物理下行链路控制信道PDCCH的最大重复次数、和调度寻呼的唤醒信号的最大重复次数，并通过系统信息块SIB将配置好的所述特殊的调度寻呼的物理下行链路控制信道PDCCH的最大重复次数、和调度寻呼的唤醒信号的最大重复次数广播给归属于该基站下的所有UE。后续寻呼过程中，如果基站本地基于UE类别配置的寻呼参数中无论是否包含所述特定UE类别对应的调度寻呼的物理下行链路控制信道PDCCH的最大重复次数、和调度寻呼的唤醒信号的最大重复次数中的至少之一，如果有为所述特定的UE类别配置的特殊调度寻呼的物理下行链路控制信道PDCCH的最大重复次数、和调度寻呼的唤醒信号的最大重复次数中的至少之一，则优先基于所述特殊调度寻呼的物理下行链路控制信道PDCCH的最大重复次数、和调度寻呼的唤醒信号的最大重复次数选择寻呼资源中的至少之一。同样的，待寻呼UE接收了基站基于UE类别配置的寻呼参数中无论是否包含了所述特定UE类别对应的调度寻呼的物理下行链路控制信道PDCCH的最大重复次数、和调度寻呼的唤醒信号的最大重复次数中的至少之一，如果所述待寻呼UE也接收了基站为所述特定的UE类别配置的特殊调度寻呼的物理下行链路控制信道PDCCH的最大重复次数、和调度寻呼的唤醒信号的最大重复次数中的至少之一，则所述待寻呼UE优先基于所述特殊调度寻呼的物理下行链路控制信道PDCCH的最大重复次数、和调度寻呼的唤醒信号的最大重复次数选择寻呼资源中的至少之一。
通过上述示例一提供的技术方案，基站基于UE类别配置寻呼参数，并将所述寻呼参数发送UE。如此，为不同UE类别合理配置不同的寻呼参数。
示例二
图3为本申请实施例一示例二提供的寻呼方法的流程示意图。如图3所示， 该方法包括：步骤301、步骤302和步骤303。
在步骤301中，eNB接收移动管理单元MME发送的寻呼消息，所述寻呼消息中携带待寻呼UE的UE类别信息。
其中，所述UE类别信息用于所述基站识别所述UE的类别；所述UE类别信息包括以下至少之一：UE功率级别信息和UE类别指示信息。
其中，所述UE功率级别信息包括UE最大发射功率信息。UE类别指示信息包括所述UE的类别，所述待寻呼UE的类别包括如下至少之一：覆盖增强功能受限UE、覆盖增强模式B受限UE、低功率级别UE、移动受限UE、处于特定覆盖增强级别的UE、以及其他具有限制UE覆盖范围特性UE。
例如，当MME向待寻呼UE发起寻呼时，向基站发送的寻呼消息中携带所述带寻呼UE的UE最大发射功率信息或者UE类别指示信息，如此所述基站可以基于所述待寻呼UE的UE最大发射功率信息或者UE类别指示信息识别出所述待寻呼UE的类别。其中，所述UE的UE功率级别信息或者UE类别可以由UE直接上报给MME，或者由UE通过eNB发送给MME。所述待寻呼UE的类别，也可以是所述待寻呼UE在MME签约的UE类别。
在步骤302中，所述eNB根据所述待寻呼UE的UE类别信息识别所述UE的类别。
例如，所述UE功率级别信息包括UE最大发射功率信息，当待寻呼UE最大发射功率为上行最大发射功率为14dBm，则eNB就可以识别所述待寻呼UE的UE类别为低功率级别UE。
例如，所述待寻呼UE的UE类别指示信息直接指示所述UE的类别为覆盖增强功能受限UE和覆盖增强模式B受限UE中的至少之一，则eNB就可以识别所述UE的类别为覆盖增强功能受限UE和覆盖增强模式B受限UE中的至少之一。
例如，所述待寻呼UE的UE类别指示信息直接指示所述UE的类别为覆盖增强功能受限UE、覆盖增强模式B受限UE和低功率级别UE，则eNB就可以识别所述待寻呼UE的类别为覆盖增强功能受限UE、覆盖增强模式B受限UE和低功率级别UE。
例如，所述待寻呼UE的UE类别指示为移动受限UE(比如：静止)且同时指示UE所处的覆盖增强级别，则eNB就可以识别所述待寻呼UE的所使用的覆盖增强级别。
例如，所述待寻呼UE的UE类别指示信息直接指示所述UE的类别为覆盖增强功能受限UE，则eNB就可以识别所述UE所使用的覆盖增强级别为覆盖增强级别0。
例如，所述待寻呼UE的UE类别指示信息直接指示所述UE的类别为覆盖增强模式B受限UE，则eNB就可以识别所述UE所使用的覆盖增强模式为覆盖增强模式A(也就是UE只能处于覆盖增强模式0和覆盖增强模式1)。
在步骤303中，所述eNB基于所述待寻呼UE的类别和所述基站基于UE类别配置的寻呼参数选择对应的寻呼资源，并在所述寻呼资源上给所述UE发送寻呼消息。
其中，基站基于UE类别配置寻呼参数，具体参见上述示例一的内容，在此不再赘述。
其中，一个UE可以具有一种或多种UE类别。
当所述待寻呼UE的类别只有一种时，且所述待寻呼UE的类别已配置有对应的寻呼参数时，则基于所述对应的寻呼参数选择所述寻呼资源。例如，所述UE的UE类别为低功率级别UE，基站也有基于低功率级别UE对应配置的寻呼参数，则说明所述寻呼UE的类别已配置有对应的寻呼参数，那么就基于低功率级别UE对应的寻呼参数选择对应的寻呼资源，并在所述寻呼资源上给所述待寻呼UE发送寻呼消息。
当所述待寻呼UE的类别为多种时，且所述待寻呼UE的多种类别的其中一种类别已配置有对应的寻呼参数时，则基于所述对应的寻呼参数选择所述寻呼资源。例如，所述待寻呼UE的类别为低功率级别UE和覆盖增强功能受限UE，但是基站只有基于低功率级别UE对应配置的寻呼参数，则说明所述待寻呼UE的两种类别的其中一种类别已配置有对应的寻呼参数，那么就基于低功率级别UE对应的寻呼参数选择对应的寻呼资源，并在所述寻呼资源上给所述UE发送寻呼消息。
当所述待寻呼UE的类别为多种时，且所述待寻呼UE的多种类别的其中多种类别已配置有对应的寻呼参数，采取如下策略一或策略二。
策略一：从已配置有对应的寻呼参数的所述待寻呼UE的类别中，基于覆盖范围最小的UE类别对应的寻呼参数选择所述寻呼资源。
策略二：从已配置有对应的寻呼参数的所述待寻呼UE的类别中，基于PDCCH或唤醒信号的最大重复次数最小的UE类别对应的寻呼参数选择所述寻 呼资源。
例如，所述待寻呼UE的类别为低功率级别UE和覆盖增强功能受限UE，基站基于低功率级别UE和覆盖增强功能受限UE都配置有各自对应的寻呼参数，则说明所述待寻呼UE的两种类别的其中两种类别都已配置有对应的寻呼参数，由于覆盖增强功能受限UE的覆盖范围<低功率级别UE的覆盖范围，那么按照策略一就可以基于覆盖增强功能受限UE对应的寻呼参数选择对应的寻呼资源，并在所述寻呼资源上给所述UE发送寻呼消息。
当所述待寻呼UE的类别未配置对应的寻呼参数时，基于传统Legacy UE对应的寻呼参数，或者基于配置的寻呼参数中覆盖范围大于等于所述待寻呼UE的UE类别对应的寻呼参数选择所述寻呼资源，所述Legacy UE对应的寻呼参数是指按小区最大覆盖范围配置的寻呼参数。
例如，所述待寻呼UE的类别为低功率级别UE和覆盖增强功能受限UE，但是基站只基于覆盖增强模式B受限UE配置有对应的寻呼参数，则说明所述待寻呼UE的UE类别未配置对应的寻呼参数，则可以选择传统Legacy UE对应的寻呼参数。
例如，所述待寻呼UE的类别为覆盖增强功能受限UE和覆盖增强模式B受限UE，但是基站只基于低功率级别UE配置有对应的寻呼参数，则说明所述待寻呼UE的类别未配置对应的寻呼参数，则可以选择传统Legacy UE对应的寻呼参数；另外，由于覆盖增强功能受限UE的覆盖范围<覆盖增强模式B受限UE的覆盖范围<低功率级别UE的覆盖范围，也可以基于低功率级别UE对应的寻呼参数选择对应的寻呼资源；还可以优先基于低功率级别UE对应的寻呼参数选择对应的寻呼资源。
另外，覆盖增强受限UE的调度寻呼的PDCCH的最大重复次数和调度寻呼的唤醒信号的最大重复次数中的至少之一可以通过标准固定为1(不重复发送)，如果标准固定为为1，则覆盖增强受限UE的PDCCH的最大重复次数和调度寻呼的唤醒信号的最大重复次数中的至少之一固定为1，不再从基站基于UE类别配置的寻呼参数和Legacy参数里选择。
通过上述示例二提供的技术方案，在寻呼过程中，基站可以基于待寻呼UE的类别和基于UE类别配置的寻呼参数选择对应的寻呼资源，并在所述寻呼资源上给所述待寻呼UE发送寻呼消息。如此对于不同类别的UE配置不同的寻呼参数，避免了下行资源浪费，实现了寻呼优化。

或者，当所述UE的类别为多种时，且所述UE的多种类别的其中一种类别已配置有对应的寻呼参数时，则基于所述对应的寻呼参数选择所述寻呼资源；
或者，当所述UE的类别为多种时，且所述UE的多种类别的其中多种类别已配置有对应的寻呼参数时，采取如下策略之一：

当所述UE的类别为多种时，且所述UE的多种类别已配置有对应的寻呼参数时，采取如下策略一、策略二或策略三。
策略一：从已配置有对应的寻呼参数的所述UE的类别中，基于覆盖范围最小的UE类别对应的寻呼参数选择所述寻呼资源。
策略二：从已配置有对应的寻呼参数的所述UE的类别中，基于PDCCH或唤醒信号的最大重复次数最小的UE类别对应的寻呼参数选择所述寻呼资源。
策略三：从已配置有寻呼参数的所述UE的多种类别中选择与至少两种类别分别对应的至少两组寻呼参数，并基于所述至少两组寻呼参数选择与所述至少两组寻呼参数分别对应的至少两组寻呼资源，并在所述至少两组寻呼资源上同时监控寻呼消息。
其中，基于对应的寻呼参数选择所述寻呼资源，包括：
如果所述对应的寻呼参数中配置有参数项，则基于配置的所述参数项选择所述寻呼资源；
如果所述对应的寻呼参数中没有配置有参数项，则基于传统Legacy UE对应的所述参数项选择所述寻呼资源；所述传统Legacy UE对应的所述参数项是指按小区最大覆盖范围配置的所述参数项；
所述参数项包括如下之一：调度寻呼的PDCCH的最大重复次数、调度寻呼的唤醒信号的最大重复次数、调度寻呼的唤醒信号的时频位置、寻呼周期、以及所述寻呼周期内的寻呼资源个数nB。
其中，基于对应的寻呼参数选择所述寻呼资源，包括：如果所述对应的寻呼参数中包含与所述UE的类别对应的可承载寻呼载波或窄带，则基于如下策略一或策略二。
策略一：如果所述载波或窄带只有一个，则基于所述载波或窄带选择所述寻呼资源。
策略二：如果所述载波或窄带存在多个，则基于如下预定义规则一和规则二选择所述载波中的一个载波或窄带中的一个窄带，基于所述一个载波或一个窄带选择所述寻呼资源。
规则一：按照(i)UE ID和载波选择权重或(ii)UE ID和窄带选择权重，将UE按选择权重比例分摊到所述载波或窄带上。
规则二：给予UE ID与载波或窄带个数取摸来将UE平均分摊到多个载波或窄带上。

示例一：
图5为本申请实施例二示例一提供的寻呼方法的流程示意图。如图5所示，该方法包括：步骤501至步骤504。
在步骤501中，用户设备UE接收基站发送的基于UE类别配置的寻呼参数。
其中，所述寻呼参数包括如下至少之一：调度寻呼的配置信息、承载寻呼的下行载波信息。
其中，基站基于UE类别配置寻呼参数的详细内容，参见实施例一，在此不再赘述。

例如，MME可以在发送给UE的附着接受ATTACH ACCEPT消息或跟踪区更新请求接受TRACKING AREA UPDATE ACCEPT消息中携带所述UE的UE类别指示信息。所述UE的类别可以为所述UE在MME中签约时的UE类别。
上述步骤501、步骤502并不存在固定的先后顺序，本示例一中的顺序仅仅是为了说明方便，并不起到限制步骤501、步骤502前后顺序的作用。
在步骤503中，所述UE基于所述UE的类别和接收的寻呼参数选择对应的寻呼资源。
其中，在所述UE基于所述UE的类别和接收的寻呼参数选择对应的寻呼资源之前，还包括：所述UE接收从MME发送的消息，该消息携带UE的类别。
在步骤504中，所述UE在所述寻呼资源上监控寻呼消息。本实施二示例一提供的技术方案，UE接收基站基于UE类别配置寻呼参数，并在寻呼过程中，基于所述UE的类别和接收的寻呼参数选择对应的寻呼资源，并在所述寻呼资源上监控寻呼消息。如此，对于不同类别的UE使用不同的寻呼参数选择寻呼资源，能够降低UE监控寻呼过程中的功率消耗，提升节能效果。
示例二：
图6为本申请实施例二示例一中步骤503详细过程的示意图。如图6所示，步骤503例如可以包括如下四种方式。
方式一：当所述UE的类别只有一种时，且所述UE的UE类别已配置有对应的寻呼参数时，则基于所述对应的寻呼参数选择所述寻呼资源。
例如，所述UE的类别为低功率级别UE，基站也有基于低功率级别UE对应配置的寻呼参数，则说明所述UE的类别与接收的寻呼参数中的一组寻呼参数对应的UE类别一致，则说明所述UE的类别已配置有对应的寻呼参数，那么就基于低功率级别UE对应的寻呼参数选择对应的寻呼资源，并在所述寻呼资源上给所述UE发送寻呼消息。
方式二：当所述UE的类别为多种时，且所述UE的多种类别的其中一种类别已配置有对应的寻呼参数时，则基于所述对应的寻呼参数选择所述寻呼资源。
例如，所述UE的类别为低功率级别UE和覆盖增强功能受限UE，但是基站只有基于低功率级别UE配置的寻呼参数，则说明所述UE的两种类别的其中一种类别与接收的寻呼参数对应的UE类别一致，则说明所述UE的多种类别的其中一种类别已配置有对应的寻呼参数，那么就基于低功率级别UE对应的寻呼参数选择对应的寻呼资源，并在所述寻呼资源上监控寻呼消息。
方式三：当所述UE的类别为多种时，且所述UE的多种类别的其中多种类别已配置有对应的寻呼参数时，采取如下策略一或策略二。
策略一：从已配置有对应的寻呼参数的所述UE的类别中，基于覆盖范围最小的UE类别对应的寻呼参数选择所述寻呼资源。
策略二：从已配置有对应的寻呼参数的所述UE的类别中，基于PDCCH或唤醒信号的最大重复次数最小的UE类别对应的寻呼参数选择所述寻呼资源。
例如，所述UE的类别为低功率级别UE和覆盖增强功能受限UE，基站基于低功率级别UE和覆盖增强功能受限UE都配置有对应的寻呼参数，则说明所述UE的两种类别的其中两种类别与接收的寻呼参数中的两组寻呼参数各自对应的UE类别一一一致，则说明所述UE的多种类别的其中多种类别已配置有对应的寻呼参数，由于覆盖增强功能受限UE的覆盖范围<低功率级别UE的覆盖范围，那么按照策略一就可以基于覆盖增强功能受限UE对应的寻呼参数选择对应的寻呼资源，并在所述寻呼资源监控寻呼消息。
方式四：当所述UE的类别未配置对应的寻呼参数时，基于传统Legacy UE对应的寻呼参数，或者基于配置的寻呼参数中覆盖范围大于等于所述UE的类别中覆盖范围最小的UE类别对应的寻呼参数选择所述寻呼资源，所述Legacy UE对应的寻呼参数是指按小区最大覆盖范围配置的寻呼参数。
例如，所述UE的类别为低功率级别UE和覆盖增强功能受限UE，但是UE接收到的只是基站只基于覆盖增强模式B受限UE对应配置的寻呼参数，则说明所述UE的类别与接收的寻呼参数的UE类别不对应，即所述UE的类别未配置对应的寻呼参数，则可以基于传统Legacy对应的寻呼参数选择寻呼资源。
例如，所述UE的类别为覆盖增强功能受限UE和覆盖增强模式B受限UE，但是UE接收到的只是基站只基于低功率级别UE对应配置的一组寻呼参数，则说明所述UE的类别与接收的寻呼参数对应的UE类别不对应，即所述UE的类别未配置对应的寻呼参数，则可以基于传统Legacy对应的寻呼参数选择寻呼资源；另外，由于覆盖增强功能受限UE的覆盖范围<覆盖增强模式B受限UE的 覆盖范围<低功率级别UE的覆盖范围，也可以基于低功率级别UE对应的寻呼参数选择对应的寻呼资源；还可以优先基于低功率级别UE对应的寻呼参数选择对应的寻呼资源。
通过上述示例二，在监控寻呼过程中，UE基于所述UE的类别和从基站接收到的基站基于UE类别配置的参数信息选择对应的寻呼资源。如此，对于不同类别的UE基于不同的寻呼参数选择寻呼资源，降低UE监控寻呼过程中的功率消耗，提升了节能效果。
示例三：
图7为本申请实施例二示例一中步骤503详细过程的示意图。如图7所示，步骤503包括如下方式一和方式二。
方式一：如果所述对应的寻呼参数中配置有参数项，则基于配置的所述参数项选择所述寻呼资源。
方式二：如果所述对应的寻呼参数中没有配置有参数项，则基于Legacy UE对应的所述参数项选择所述寻呼资源；所述Legacy UE对应的所述参数项是指按小区最大覆盖范围配置的所述参数项。
所述参数项包括如下之一：
调度寻呼的PDCCH的最大重复次数、调度寻呼的唤醒信号的最大重复次数、调度寻呼的唤醒信号的时频位置、寻呼周期、以及所述寻呼周期内的寻呼资源个数nB。
例如，所述对应的寻呼参数中包括调度寻呼的配置信息，所述调度寻呼的配置信息里可以包含如下至少之一：寻呼周期Paging Cycle(例如寻呼的DRX周期)、一个寻呼周期里的寻呼时机个数nB(即寻呼周期内的寻呼资源个数)、寻呼调度的PDCCH的最大重复次数、寻呼调度的Wackup信号的最大重复次数、以及调度寻呼的唤醒信号的时频位置。

例如，所述UE为覆盖增强模式受限UE、覆盖增强模式B受限UE和低功率级别UE，基站也有基于覆盖增强模式受限UE、覆盖增强模式B受限UE和低功率级别UE对应配置的寻呼参数，则说明所述UE的类别与接收的寻呼参数中的一组寻呼参数对应的UE类别一致，则说明所述UE的类别已配置有对应的寻呼参数，那么就可以基于上述策略，比如选择基于覆盖增强模式受限UE对应的寻呼参数选择对应的寻呼资源；与此同时，还可以基于低功率级别UE对应的寻呼参数选择另一种寻呼资源，还可以基于覆盖增强模式B受限UE对应的寻呼参数选择再另一种寻呼资源，并同时在所述寻呼资源、所述另一种寻呼资源和再另一种寻呼资源，即三种寻呼资源上同时监控寻呼消息。
