寻呼方法、终端及基站
相关申请的交叉引用
本申请主张在2017年12月15日在中国提交的中国专利申请号No.201711346231.8的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其是指一种寻呼方法、终端及基站。
背景技术
物联网业务需要极长的待机时间，例如两节5号电池十年待机等。在相关技术中的基于蜂窝的窄带物联网(Narrow Band Internet of Things，NB-IoT)标准中，规范了终端可以进入长期的不连续接收状态DRX以节电。但是，节电的同时也会增加终端响应基站寻呼的时延。对部分应用如共享单车等，终端响应时延增加会大大降低用户体验。
为了优化快速响应基站寻呼的情况下的终端功耗，标准中提出了轻量级寻呼的概念，其概念为在检测寻呼信号之前增加一个轻量级的信号(唤醒信号)。只有在检测到此唤醒信号后，终端才会进行后续寻呼信号的检测。由于此信号携带信息量较小，只需较小的重复次数即可覆盖小区，且空闲态下大多数寻呼时机内都并没有实际发送寻呼，因此引入唤醒信号可大大降低终端的功耗。
寻呼消息(Paging message)的物理下行控制信道(Physical Downlink Control Channel，PDCCH)是使用P-RNTI进行加扰的，并且在PDCCH中没有终端ID相关的信息。因此，相关技术中，终端需要一直到解开寻呼消息才知道此寻呼是否是针对自己发送的。由于需要解开数据信道的原因，终端的功耗较高。由于向后兼容的问题，故难以通过修改PDCCH本身的内容和加扰方式来使终端提前得知寻呼是否是针对自身发送的问题。

具体实施方式
为使本公开要解决的技术问题、技术方案和特点更加清楚，下面将结合附图及具体实施例进行详细描述。
如图1所示，本公开实施例提供一种寻呼方法，应用于终端，包括：
步骤11，接收基站发送的唤醒信号；
步骤12，若所述唤醒信号是与终端匹配的唤醒信号，监听用于寻呼的物理下行控制信道PDCCH。
本公开的上述实施例中，唤醒信号是一个轻量级的信号，即该唤醒信号携带的信息量较小；终端对唤醒信号进行接收和解调的过程仅需要消耗较小的资源；相对于直接接收和解调PDCCH以及寻呼消息所消耗的资源，解调 唤醒信号确定是否进一步监听和解调PDCCH以及寻呼消息的方式能够大大降低终端的功耗。
可选的，本公开的上述实施例提供的寻呼方法是应用于不连续接收DRX状态下的寻呼方法，上述步骤11和步骤12均是终端在DRX的唤醒时间内执行的；具体处于DRX的唤醒时间的哪个具体时隙，在此不作具体限定。
需要说明的是，本公开的上述实施例中，若唤醒信号是与终端匹配的唤醒信号，则表明在该DRX周期的唤醒时间内基站发送的PDCCH和寻呼消息是针对该终端，进一步的终端继续监听用于寻呼的PDCCH；若用于寻呼的PDCCH内含有P-RNTI(P-RNTI用于标识寻呼消息的传输)，则终端继续监听寻呼消息并对寻呼消息进行解调。
综上，本公开的上述实施例中，终端在检测PDCCH和寻呼消息之前，先检测是否存在与该终端匹配的唤醒信号，若存在与该终端匹配的唤醒信号，终端才会进行后续PDCCH和寻呼消息的检测；由于唤醒信号携带的信息量较小，因此引入唤醒信号能够大大降低终端的功耗。
进一步的，本公开的上述实施例中步骤11之后，该寻呼方法还包括：
若所述唤醒信号不是与终端匹配的唤醒信号，控制所述终端进入睡眠状态。
具体的，若唤醒信号不是与终端匹配的唤醒信号，则表明在该DRX周期的唤醒时间内基站发送的PDCCH和寻呼消息不是针对该终端(其可能是针对其他终端)，则终端无需进一步监听用于寻呼的PDCCH，其能够降低终端功耗。
可选的，本公开的上述实施例中步骤11之后，所述寻呼方法还包括：
解析所述唤醒信号，确定所述唤醒信号是否是与终端匹配的唤醒信号。
具体的，所述解析所述唤醒信号，确定所述唤醒信号是否是与终端匹配的唤醒信号的步骤，包括：

可选的，可以将小区中的多个终端按照终端ID分成若干组，每个终端组 也有各自的标识信息。例如，终端A所在的终端组的标识信息为标识1，则终端A接收到的唤醒信号中若携带标识1，则表明该唤醒信号是与该终端A匹配的唤醒信号；或者，终端A接收到的唤醒信号中若携带终端A的IMSI，则同样表明该唤醒信号是与终端A匹配的唤醒信号。
进一步的，若终端A接收到的唤醒信号中携带标识2(该标识2对应其他的终端组)或者其他终端的IMSI，则此种情况下表明该唤醒信号不是与终端A匹配的唤醒信号。
或者，所述解析所述唤醒信号，确定所述唤醒信号是否是与终端匹配的唤醒信号的步骤，包括：
解析所述唤醒信号，获取所述唤醒信号的格式信息；
若所述唤醒信号的格式信息与终端的标识信息对应的唤醒信号的格式信息相同，或者，所述唤醒信号的格式信息与终端所在的终端组的标识信息对应的唤醒信号的格式信息相同，确定所述唤醒信号是与终端匹配的唤醒信号；否则，确定所述唤醒信号不是与所述终端匹配的唤醒信号。
本公开的上述实施例中，不同终端可以对应唤醒信号的不同格式信息，其终端的标识信息与唤醒信号的格式信息之间的对应关系可以是预先约定或预先配置的。或者，不同终端组对应唤醒信号的不同格式信息，其终端组的标识信息与唤醒信号的格式信息之间的对应关系也可以是预先约定或者预先配置的，在此不作具体限定。
例如，终端B对应的唤醒信号的格式信息为格式1，若终端B接收到的唤醒信号采用格式1，则表明该唤醒信号是与终端B匹配的唤醒信号；或者，终端B所在的终端组的格式信息为格式1，若终端B接收到的唤醒信号采用格式1，则表明该唤醒信号是与终端B匹配的唤醒信号。
进一步的，若终端B接收到的唤醒信号采用格式2或者其他格式，则此种情况下表明该唤醒信号不是与终端B匹配的唤醒信号。
可选的，本公开的上述实施例中，唤醒信号可以采用类似基于物联网的辅同步信号(NB-IoT Secondary Synchronization Signal，NB-SSS)的设计。具体的，唤醒信号在频域上使用ZC序列(其长度可以为11)，该唤醒信号在时域上使用正交掩码OCC。
具体的，若所述唤醒信号在频域上使用ZC序列；
则所述解析所述唤醒信号，确定所述唤醒信号是否是与终端匹配的唤醒信号的步骤，包括：

本公开的上述实施例中，终端接收到唤醒信号之后，对唤醒信号的时域和/或频域进行解析，若在频域上解析得到的ZC序列的根指数与终端的标识信息或终端所在的终端组的标识信息对应，则确定该唤醒信号是与终端匹配的唤醒信号；和/或，若在时域上解析得到的OCC掩码的取值与终端的标识信息或终端所在的终端组的标识信息对应，则确定该唤醒信号是与终端匹配的唤醒信号。
可选的，本公开的上述实施例中，所述终端的标识信息为所述终端的国际移动用户识别码IMSI。
综上，本公开的上述实施例中，在向终端发送用于寻呼的物理下行控制信道PDCCH或者在向终端发送寻呼消息之前，基站向终端发送一唤醒信号，且该唤醒信号与至少一个终端匹配；终端接收到与自身匹配的唤醒信号之后，才继续监听后续的用于寻呼的PDCCH以及寻呼消息，而终端未接收到与自身匹配的唤醒信号或者终端未接收到唤醒信号，则终端进入睡眠状态不再监听PDCCH，从而达到降低终端功耗的目的。
