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。
应理解，本申请实施例的技术方案可以应用于各种通信***，例如：全球移动通讯(Global System of Mobile communication，GSM)***、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)或全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信***、新无线(New Radio,NR)***(或者说，5G***)、4.5G***。
本申请实施例所涉及到的终端设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)，终端(terminal)，终端设备(terminal device)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端设备。
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GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是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、可穿戴设备等，本申请实施例并不限定。
应理解，本申请中的波束组可以是指终端设备可以同时通过多个波束与网络设备进行通信，这个波束组可以是网络设备通过信道测量进行划分并通知给终端设备，也可以是终端设备通过广播消息获取的。例如，图2示出了本申请实施例中波束组与子帧之间的对应关系。
图3是本申请实施例的应用场景示意图。如图3所示，网络设备和终端设备之间可以通过波束进行通信。其中，每个波束可以用于映射无线帧中的一个时间单元。该时间单元可以是子帧、时隙或符号。网络设备可以为不同方向或不同组合的波束分配波束标识。例如，如图1所示，不同方向的波束或波束组具有不同的波束标识。在图1中，波束标识可以表示为B0，B1，B2，B3，B4，B5。在图2中，波束组被标识为B0，B1，B2，B3，B4，B5。
本申请实施例中的一轮波束扫描可以指网络设备在遍历一次所有空间方向的波束的过程。或者，也可以理解为，网络设备在一轮波束扫描过程中发送了全部空间方向的波束。例如，在图1中，一轮波束扫描可以指波束B0扫描至波束B5的过程。在图2中，一轮波束扫描可以指B0波束组扫描至B4波束组的过程。
可选地，网络设备可以根据顺序扫描发送波束或波束组，或者网络设备也可以通过其他预定的方式发送波束或波束组。
图4是本申请实施例的用于寻呼的方法100的示意图。如图4所示，该方法100可以由终端设备执行，包括：
S101，终端设备确定目标时间区间；
S102，终端设备在所述目标时间区间侦听信道，以获取寻呼信息，其中，所述目标时间区间属于目标时间窗，所述目标时间窗内的多个波束映射的时间单元均携带所述寻呼信息。
可选地，上述时间单元指时间资源单位。例如，时间单元可以是子帧、时隙或符号。时间单元也可以是其他用时间表征的时间资源单位。
可选地，上述目标时间窗可以指一个时间区间或一个时间段。
可选地，上述多个波束可以属于一个或多个波束组。
应理解，网络设备可以在上述目标时间窗内发送所述多个波束，所述多个波束映射的时间单元均携带所述寻呼信息。终端设备若在目标时间窗包含的时间区间内侦听信道，则可以获取寻呼信息。
可选地，上述时间单元均携带的寻呼信息是相同的寻呼信息，因此，终端设备接收到其中任何一条寻呼信息既可以获取需要的寻呼信息。
在本申请实施例中，终端设备确定目标时间区间，并在目标时间区间内侦听网络设备发送的多个波束，以获取寻呼信息。该目标时间区间属于目标时间窗，终端设备在连续的目标时间窗内接收的多个波束映射的子帧均携带寻呼信息，从而提高了终端设备在目标时间区间内接收到寻呼信息的概率，进而提高了终端设备获取寻呼信息的效率。
可选地，上述多个波束可以包含至少两个方向不同的波束。
应理解，因为上述多个波束中包含至少两个方向不同的波束，从而增大了携带寻呼信息的波束的覆盖区域，因此也增加了终端设备在该多个波束的覆盖区域内的概率，提高了终端设备接收较好的信号质量的寻呼信息的可能性，进而提高了终端设备获取寻呼信息的效率。
可选地，上述多个波束可以包含一轮波束扫描的波束。
应理解，由于网络设备在目标时间窗内发送的波束包含一轮波束扫描的波束，且目标时间窗内发送的波束映射的时间单元都映射寻呼信息。一轮波束扫描的波束提高了映射信 息的波束在空间上的覆盖范围，因此可以保证无论终端设备处于小区中的任何位置，都能够接收到保证信号质量的波束映射的寻呼信息。从而提高了终端设备接收寻呼信息的效率。
可选地，上述寻呼信息可以包括但不限于以下内容：针对一个或多个终端设备执行随机接入的前导码信息、执行所述随机接入过程的时域资源信息、执行所述随机接入过程的频域资源信息、执行所述随机接入过程的波束信息，以指示终端设备执行随机接入的资源位置或配置信息。上述前导码，时域信息，频域信息可以与业务类型相对应，并且可以采用索引(英文：index)方式进行发送，以便于网络设备根据终端设备回应的前导码，时域，频域位置获知所述终端设备将要发起的业务类型或分配对应的资源大小。作为一个示例，如果网络设备将要寻呼时延要求高的业务，那么所述网络设备可以将前导码(英文：preamble)定义为preamble 1，在子帧0和子载波1上进行发送，那么当所述网络设备在子帧0，子载波1上接收到了preamble 1，那么所述网络设备就可以分配较快的调度方式，比如使用较短的TTI长度，调度所述随机过程中的其他消息(比如随机接入过程中的消息3)，以方便所述终端设备尽快建立无线连接。
可选地，寻呼信息里还可以是一个指示信息，用于指示第二寻呼信息的位置。举例来讲，寻呼信息中指示第一终端设备有第二寻呼信息，并指示所述第二寻呼信息的资源位置信息。如果所述第一终端设备接收到所述寻呼信息，则执行在所述资源位置上接收所述第二寻呼信息。如果是第二终端设备接收到所述寻呼信息发现没有指示其接收所述第二寻呼信息的指示，那么所述第二终端设备则不执行接收第二寻呼消息的过程。这样做降低了所述寻呼信息的大小，节省了寻呼的负载。
可选地，所述寻呼信息内包含终端设备的临时标识，比如小区无线网络临时标识(cell Radio Network Temporary Identifier,C-RNTI)。例如，针对小小区，当终端设备不需要执行上行同步过程时，可以通过上行资源发送所述临时标识，从而减少建立连接时延。可选的，所述寻呼信息还可以携带上行资源位置信息等内容，方便所述终端设备在所述上行资源位置上发送所述临时标识。
可选地，所述终端设备确定所述目标时间区间，包括：所述终端设备确定所述目标时间窗；所述终端设备根据所述目标时间窗，确定所述目标时间区间。
应理解，终端设备可以将目标时间窗占据的整个时间段确定为目标时间区间。或者，终端设备也可以将目标时间窗中的部分时间段确定为目标时间区间。或者说，终端设备可以在整个目标时间窗内侦听信道，以获取寻呼信息，或，终端设备也可以在目标时间窗内的部分时间区间内侦听信道，以获取寻呼信息。
在本申请实施例中，终端设备确定目标时间窗，并根目标时间窗确定目标时间区间，在目标时间区间内侦听网络设备发送的多个波束，以获取寻呼信息。网络设备在目标时间窗内发送的多个波束映射的子帧均携带寻呼信息，从而提高了终端设备在目标时间区间内接收到寻呼信息的概率，进而提高了终端设备获取寻呼信息的效率。
可选地，终端设备确定目标时间窗有多种方法。作为一个示例，网络设备可以向终端设备发送指示信息，该指示信息可以指示目标时间窗。
作为另一个示例，网络设备可以向终端设备发送寻呼配置信息和波束配置信息。所述寻呼配置信息用于指示携带寻呼信息的第一寻呼时间单元，所述波束配置信息包括所述网 络设备发送的波束与其映射的时间单元之间的对应关系。终端设备可以根据所述寻呼配置信息确定第一寻呼时间单元，所述第一寻呼时间单元是携带寻呼信息的时间单元。终端设备确定目标时间窗，包括：所述终端设备根据所述第一寻呼时间单元和所述对应关系确定目标时间窗。
在本申请实施例中，终端设备可以确定寻呼配置信息和波束配置信息，并根据寻呼配置信息和波束与时间单元之间的对应关系，确定目标时间窗，以接收寻呼信息。提高了接收寻呼信息的效率。
可选地，上述寻呼配置信息可以包括第一配置信息和第二配置信息，所述第一配置信息用于指示所述携带所述寻呼信息的无线帧的位置，所述第二配置信息用于指示所述第一寻呼时间单元在所述寻呼无线帧中的位置。
可选地，上述波束配置信息可以是波束发送的图样(英文：pattern)信息。寻呼配置信息可以包括：寻呼的周期，小区内寻呼的负载间隔或单位时间内的寻呼时隙个数等，例如参数T(表示寻呼周期)，和nB(用于指示单个非连续接收(Discontinuous Reception,DRX)周期内的执行寻呼的次数。即单个DRX周期内寻呼时刻(Paging Occasion,PO)的次数。nB的值越大，表示寻呼的能力越大)。
作为一个具体示例，下文介绍终端设备根据寻呼配置信息确定第一寻呼时间单元的方式。该第一寻呼时间单元可以是寻呼时刻(Paging Occasion,PO)。
在第一部分，终端设备根据寻呼配置信息，计算寻呼信息所在的无线帧。
例如，终端设备可以根据公式PF＝SFN mod T＝(T div N)*(UE_ID mod N)，计算寻呼信息所在的无线帧。
其中，PF表示包含一个到多个PO的无线帧；
SFN表示***帧号；mod表示取余数；div表示相除；T表示寻呼周期；N表示表示在一个DRX周期的寻呼无线帧个数。作为一个示例，终端设备可以根据nB确定N,nB和N的映射关系如表1所示；UE_ID表示IMSI mod 1024；其中IMSI表示国际移动用户识别码(International Mobile Subscriber Identification Number,IMSI)。IMSI可以使用十进制表示,IMSI可以保存在全球用户识别卡(Universal Subscriber Identity Module,USIM)中。

在第二部分，终端设备可以计算PO在PF中的位置。
可选地，终端设备可以根据公式，i_s＝floor(UE_ID/N)mod Ns，计算PO。
其中，i_s表示在子帧指示PO的索引。floor()表示向下取整。
终端设备可以根据索引i_s确定PO的位置。例如，表2和表3分别示出了在频分双工(Frequency division duplex，FDD)和时分双工(Time Division Duplex，TDD)两种情况下索引i_s与PO的关系。
表2(FDD模式)
Ns PO(i_s＝0) PO(i_s＝1) PO(i_s＝2) PO(i_s＝3)
1 9 N/A N/A N/A
2 4 9 N/A N/A
4 0 4 5 9
其中，Ns表示表示一个无线帧中有几次寻呼子帧的机会。以第2行为例，这里Ns＝2，表示一个无线帧内的寻呼机会有2个，i_s分别是0和1，子帧分别是子帧4和子帧9。
表3(TDD模式)
Ns PO(i_s＝0) PO(i_s＝1) PO(i_s＝2) PO(i_s＝2)
1 0 N/A N/A N/A
2 0 5 N/A N/A

可选地，终端设备可以根据所述第一寻呼时间单元和所述对应关系确定目标时间窗，包括：所述终端设备确定所述第一寻呼时间单元映射的第一波束；所述终端设备根据所述第一波束，确定所述目标时间窗，其中，所述多个波束包括所述第一波束。
可选地，上述目标时间窗可以是从预设的第二波束开始进行一轮波束扫描的时间区间。
其中，该预设的第二波束可以是网络设备和终端设备预先约定的波束。例如，可以是网络设备在预设第二波束之后，向终端设备指示该第二波束的标识。
作为一个具体实施例，图5示出了终端设备确定目标时间区间的示意图。本申请的实施例以波束与时间单元对应为例进行描述，本领域技术人员能够理解，本申请各实施例也可以应用于波束组与时间单元对应的情况。
如图5所示，上述终端设备可以是第一终端设备、第二终端设备或第三终端设备。假设时间单元是子帧，上述第一寻呼时间单元可以称作第一寻呼子帧，上述预设的第二波束可以是B0。因此，一轮波束扫描开始以B0开始，以B5为结束。
对于第一终端设备，假设第一终端设备已经确定第一终端设备的第一寻呼子帧为子帧0，子帧0对应的波束为B0。因此，目标时间窗为B0开始到B5的时间区间，其对应的子帧为子帧0到子帧5。即子帧0到子帧5都携带有寻呼信息。第一终端设备可以在目标时间窗内接收寻呼信息，
同理，对于第二终端设备，假定其确定的第一寻呼子帧为子帧5，对应的波束为B5，因此目标时间窗依然为发送B0到B5的时间区间，第二终端设备可以在B0到B5的发送时间区间内侦听信道，B0到B5映射的子帧对应为子帧0到子帧5。即子帧0到子帧5都携带有寻呼信息。
对于第三终端设备，假定其确定的第一寻呼子帧为子帧9，其对应的波束为B3，因此确定的目标时间窗为B0到B5的时间区间，并且B0到B5映射的子帧为子帧6到下一个帧的子帧1。即子帧6到下一个帧的子帧1都携带有寻呼信息。
可选地，所述目标时间窗为从所述第一波束开始进行一轮波束扫描的时间区间。所述目标时间区间可以是所述目标时间窗的全部或部分时间区间。
作为一个具体实施例，图6示出了终端设备确定目标时间区间的示意图。如图6所示，上述终端设备可以是第一终端设备、第二终端设备或第三终端设备。假设时间单元是子帧，上述第一寻呼时间单元可以称作第一寻呼子帧，上述预设的第二波束可以是B0。因此，一轮波束扫描开始以B0开始，以B5为结束。
为了便于描述第一终端设备、第二终端设备、第三终端设备确定的第一寻呼子帧与图5的实施例相同，分别还是子帧0，5，9。但在图6的实施例中，目标时间窗的起始位置从第一寻呼子帧开始。
对于第一终端设备，其第一寻呼子帧是子帧0，子帧0对应波束B0，因此其目标时间窗为发送B0到B5的时间区间，B0到B5映射的子帧对应为子帧0到子帧5。即子帧0到子帧5都携带有寻呼信息。
对于第二终端设备，其第一寻呼子帧是子帧5，子帧5对应波束B5，因此其目标时间窗为发送B5到B0的时间区间，B5到B0映射的子帧对应为子帧5到下个帧的子帧0。即子帧5到下个帧的子帧0都携带有寻呼信息。
对于第三终端设备，其第一寻呼子帧是子帧9，子帧9对应波束B3，因此其目标时间窗为发送B3到B2的时间区间，B3到B2映射的子帧对应为子帧9到下个帧的子帧4。即子帧9到下个帧的子帧4都携带有寻呼信息。所述目标时间区间可以是所述目标时间窗的全部或部分时间区间。
作为一个示例，终端设备可以不必在整个目标时间窗的时间区间内侦听信道，可以只在目标时间窗内确定目标时间区间，只在该目标时间区间内侦听信道。从而节约了终端设备的功率和资源。可选地，该目标时间区间可以包括至少一个时间单元的长度。可选地，该目标时间区间内发送的波束所可以是终端设备接收的信号质量符合预设接收条件的波束，以确保终端设备正确地接收寻呼信息。
作为一个示例，在方法100中，终端设备可以确定接收的信号质量符合预设接收条件的第三波束。所述终端设备根据所述目标时间窗确定目标时间区间，包括：所述终端设备确定所述第三波束在所述目标时间窗中的发送位置；所述终端设备将所述第三波束在所述目标时间窗中的发送位置确定为所述目标时间区间。
在本申请实施例中，终端设备可以在第三波束在所述目标时间窗中的发送位置确定为目标时间区间，并在该目标时间区间内侦听信道，其中，所述第三波束是接收的信号质量符合预设接收条件的波束，从而确保终端设备正确地接收寻呼信息，并节约了功率。
可选地，终端设备可以通过对接收到波束的信号进行测量确定接收到信号质量符合预 设接收条件的第三波束。或者终端设备也可以通过其他方式确定第三波束，本申请实施例对此不作限定。
作为一个具体实施例，图7示出了本申请实施例中终端设备确定目标时间区间的示意图。如图7所示，假设时间单元是子帧，上述第一寻呼时间单元可以称作第一寻呼子帧。上述第三波束例如可以是终端设备接收的信号质量最好的波束。
在图7的方法中，终端设备确定目标时间窗的方法可以与图5的方法相同，即目标时间窗是以预设的第二波束开始进行一轮波束扫描的时间区间。假设该第二波束是波束B0。假设第三波束是波束B1。假设终端设备确定的第一寻呼子帧是子帧9，子帧9对应波束B3。
由于终端设备接收信号质量符合预设接收条件的波束是波束B1。而在子帧9上对应的波束B3的信号接收质量可能并不符合预设接收条件。因此，终端设备可以通过B3的位置索引到B1所在的子帧位置。
在图7中，根据图5中确定目标时间窗的方法，终端设备确定的目标时间窗从B0开始扫描至B5。其对应的子帧为子帧6至下个子帧1。由于终端设备可以确定B1在B3之前2个子帧的位置。因此，终端设备可以在子帧9向前索引2个子帧，得到子帧7。上述子帧7所在的位置即可以确定为目标时间区间。即终端设备可以在子帧7的位置侦听信道，以获取寻呼信息。
可选地，根据第一寻呼子帧确定目标时间区间的计算方法可以表示为：
第一寻呼子帧+offset＝第一寻呼子帧+(第一寻呼子帧-目标寻呼子帧)。
其中，目标寻呼子帧是指目标时间窗内信号接收质量最好的波束映射的子帧。offset指第一寻呼子帧与目标寻呼子帧之间的差值。
作为一个具体实施例，图8示出了本申请另一实施例中终端设备确定目标时间区间的示意图。如图8所示，假设时间单元是子帧，上述第一寻呼时间单元可以称作第一寻呼子帧。上述第三波束例如可以是终端设备接收的信号质量最好的波束。
在图8的方法中，终端设备确定目标时间窗的方法可以与图6的方法相同，即目标时间窗是以第一波束开始进行一轮波束扫描的时间区间。假设第三波束是波束B1。假设终端设备确定的第一寻呼子帧是子帧5，子帧5对应波束B5。
由于终端设备接收信号质量符合预设接收条件的波束是波束B1。而在子帧5上对应的波束B5的信号接收质量可能并不符合预设接收条件。因此，终端设备可以通过B5的位置索引到B1所在的子帧位置。
在图8中，根据图6中确定目标时间窗的方法，终端设备确定的目标时间窗从B5开始扫描至B4。其对应的子帧为子帧5至下个子帧0。终端设备可以确定B1在B5之后2个子帧的位置。因此，终端设备可以在子帧5向后索引2个子帧，得到子帧7。上述子帧7所在的位置即可以确定为目标时间区间。即终端设备可以在子帧7的位置侦听信道，以获取寻呼信息。
可选地，根据第一寻呼子帧确定目标时间区间的计算方法可以表示为：
第一寻呼子帧+offset＝第一寻呼子帧+(目标寻呼子帧-第一寻呼子帧)。
其中，目标寻呼子帧是指目标时间窗内信号接收质量最好的波束映射的子帧。offset指目标寻呼子帧与第一寻呼子帧之间的差值。
