Description

一种寻呼指示方法、基站及终端 技术领域
本发明涉及通信技术领域，尤其涉及一种寻呼指示方法、基站及终端。
背景技术
在无线通信系统中，被寻呼终端(User Equipment，UE)监听基站的寻呼信息时，主要与指示信道和寻呼消息信道有关。例如，在通用移动通信系统(Universal Mobile Telecommunications System，UMTS)中，指示信道可以为寻呼指示信道(Page Indication Channel，PICH)，寻呼消息信道可以为从公共控制物理信道(Secondary Common Control Physical Channel，SCCPCH)。一个小区可以配置多个SCCPCH，一个SCCPCH与一个特定的PICH对应。
PICH的编解码方式比SCCPCH的编解码方式简单，为了减小UE的耗电量，在监听寻呼信息时，UE并不直接解调SCCPCH中的寻呼消息，而是先解调PICH中的寻呼指示。小区中的所有UE根据国际移动用户识别码(International Mobile Subscriber Identity，IMSI)被划分为多个分组，每个分组中的UE对应PICH中承载的寻呼指示中1个比特的寻呼指示，该寻呼指示用于指示该分组中的UE是否被潜在寻呼。UE在特定时刻解调PICH，并在确定该UE所在分组对应的寻呼指示指示被潜在寻呼时，确定自身可能会被寻呼，从而接收并解调该PICH对应的SCCPCH中的寻呼消息，并根据SCCPCH中承载的寻呼消息确定自身是否真正被寻呼；在确定该UE所在分组对应的寻呼指示指示未被潜在寻呼时，则不会接收并解调该PICH对应的SCCPCH中的寻呼消息，其中，通过PICH和SCCPCH发送信号的时序关系示意图可以参见图1。
随着UE数目的增长，尤其是在机器类通信(Machine Type Communication，MTC)场景下UE的数目成倍增长，与PICH中1个比特的寻呼指示对应的一个分组中UE的数目也相应增加。由于SCCPCH 的数量有限，且每个SCCPCH中能承载的UE寻呼记录的数目也有限(例如，小于或者等于8个)，因而将导致大量UE在检测到PICH中对应的寻呼指示后，需要进一步解调SCCPCH，而在解调SCCPCH之后，仅有很少的UE检测到真正被寻呼，更多的UE未真正被寻呼，从而导致大量UE进行不必要的SCCPCH解调，增大了无线通信系统的资源开销。
发明内容
本发明实施例提供一种寻呼指示方法、基站及终端，在进行寻呼时，能够降低系统资源开销。
为达到上述目的，本发明的实施例提供如下技术方案：
第一方面，本发明的实施例提供一种寻呼指示方法，包括：基站根据至少一个终端各自的预设参数，利用预设的n(大于1的整数)个映射函数中的每个映射函数，分别将至少一个终端映射到至少两个分组中，预设参数包括至少一个终端各自的用户标识，生成与n个映射函数一一对应的n个寻呼指示集合，每个寻呼指示集合中包括的寻呼指示分别与，由每个寻呼指示集合对应的映射函数所映射的一个分组一一对应，寻呼指示用于指示对应的分组中包括的终端是否被潜在寻呼，并通过至少一个信道将n个寻呼指示集合发送给至少一个终端；终端接收基站通过至少一个信道发送的n个寻呼指示集合，根据预设参数和预设的n个映射函数，分别从n个寻呼指示集合的每个寻呼指示集合中，确定与终端对应的寻呼指示，并根据寻呼指示的指示信息，确定终端是否被潜在寻呼。
这样，基站通过利用预设的n(大于1的整数)个映射函数中的每个映射函数，分别将至少一个终端映射到至少两个分组中，从而通过n个映射函数将至少一个终端映射到数量更多的分组中，因而可以减少每个分组中包括的终端的数量。其中，n个映射函数与n个寻呼指示集合一一对应，每个分组中的终端根据n个寻呼指示集合中与自身对应的n个寻呼指示，确定是否被潜在寻呼，从而可以使得根据该n个寻呼指示进行不必要的寻呼消息信道解调的终端的数量，小于现有技术中根据单个寻呼指 示进行不必要的寻呼消息信道解调的终端的数量，因而可以降低系统资源开销。
结合第一方面，在第一方面的第一种可能的实现方式中，预设的n个映射函数相互正交，基站利用预设的n个映射函数中的每个映射函数，分别将至少一个终端映射到至少两个分组中包括：基站通过第i个映射函数将至少一个终端映射到Ni个分组中；基站通过第i+1个映射函数分别将第i个映射函数对应的Ni个分组中，每个分组包括的终端映射到Ni+1个分组中；其中，i依次取[1,n)范围内的整数，Ni为大于1的整数，Ni+1为大于1的整数。
这样，可以使得至少一个终端最终被n个映射函数映射为
Figure PCTCN2016084207-appb-000001
个分组，且不同分组中包括的终端没有重叠部分，从而可以进一步减少进行不必要的寻呼消息信道解调的终端的数量，节省资源开销。
结合第一方面或第一方面的第一种可能的实现方式，在第一方面的第二种可能的实现方式中，当至少一个信道的数量为多个时，每个信道分别承载n个寻呼指示集合中的至少一个寻呼指示集合，当通过多个信道分别发送n个寻呼指示集合中的第一个寻呼指示集合时，第一个寻呼指示集合在多个信道上的起始发送时刻保持同步。
这样，可以尽量减少终端从不同信道中接收寻呼指示集合的时间间隔，减少终端检测不同信道上与自身对应的不同寻呼指示的最大时间间隔，降低寻呼指示集合的检测时间，提高处理效率。
结合第一方面至第一方面的第二种可能的实现方式中的任意一种，在第一方面的第三种可能的实现方式中，该至少一个信道中，任一信道承载n个寻呼指示集合中的至少一个寻呼指示集合，至少一个寻呼指示集合在任一信道上以寻呼指示集合为单位分段排列，或者，多个寻呼指示集合中不同寻呼指示集合中的寻呼指示在任一信道中交叉排列。
这样，当多个寻呼指示集合中不同寻呼指示集合中的寻呼指示在 任一信道上交叉排列时，可以降低终端检测不同寻呼指示集合中，与自身对应的两个寻呼指示的最小检测间隔，从而提高处理效率。
结合第一方面至第一方面的第三种可能的实现方式中的任意一种，在第一方面的第四种可能的实现方式中，终端根据寻呼指示的指示信息，确定终端是否被潜在寻呼包括：若n个寻呼指示集合的每个寻呼指示集合中，与终端对应的寻呼指示均指示被潜在寻呼，则终端确定终端被潜在寻呼；若n个寻呼指示集合的任一寻呼指示集合中，与终端对应的寻呼指示指示未被潜在寻呼，则终端确定终端未被潜在寻呼。
结合第一方面至第一方面的第四种可能的实现方式中的任意一种，在第一方面的第五种可能的实现方式中，该方法还包括：基站通过至少一个寻呼消息信道向至少一个终端发送寻呼消息；若终端确定被潜在寻呼，则解调对应的寻呼消息信道。
第二方面，提供一种基站，该基站包括：处理器，用于根据至少一个终端各自的预设参数，利用预设的n个映射函数中的每个映射函数，分别将至少一个终端映射到至少两个分组中，其中，n为大于1的整数，预设参数包括至少一个终端各自的用户标识；处理器还用于，生成与n个映射函数一一对应的n个寻呼指示集合，其中，每个寻呼指示集合中包括的寻呼指示分别与，由每个寻呼指示集合对应的映射函数所映射的一个分组一一对应，寻呼指示用于指示对应的分组中包括的终端是否被潜在寻呼；发射机，用于通过至少一个信道将n个寻呼指示集合发送给至少一个终端。
其中，第二方面提供的基站，可以用于执行上述第一方面及第一方面的任一种可能的实现方式对应的寻呼指示方法，其对应的有益效果具体可以参见上述方法中的相关描述。
第三方面，提供一种终端，该终端包括：接收机，用于接收基站通过至少一个信道发送的n个寻呼指示集合；处理器，用于根据预设参数和预设的n个映射函数，分别从n个寻呼指示集合的每个寻呼指示集合中，确定与终端对应的寻呼指示，预设的n个映射函数与n个寻呼指示集合一一对应，预设参数包括终端的用户标识；处理器还用 于，根据寻呼指示的指示信息，确定终端是否被潜在寻呼。
其中，第三方面提供的终端，可以用于上述执行第一方面及第一方面的任一种可能的实现方式对应的寻呼指示方法，其对应的有益效果具体可以参见上述方法中的相关描述。

无线通信网络，是一种提供无线通信功能的网络。无线通信网络可以采用不同的通信技术，例如码分多址(Code Division Multiple Access，CDMA)、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency-division Multiple access，OFDMA)、单载波频分多址(Single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(Generation)网络、3G网络或者4G网络。典型的2G网络包括全球移动通信系统(Global System For Mobile Communications/General Packet Radio Service，GSM)网络或者通用分组无线业务(General Packet Radio Service，GPRS)网络，典型的3G网络包括通用移动通信系统(Universal Mobile Telecommunications system，UMTS)网络，典型的4G网络包括长期演进(Long Term Evolution,LTE)网络。其中，UMTS网络有时也可以称为通用陆地无线接入网(Universal Terrestrial Radio Access Network，UTRAN)，LTE网络有时也可以称为演进型通用陆地无线接入网(Evolved Universal Terrestrial Radio  Access Network，E-UTRAN)。根据资源分配方式的不同，可以分为蜂窝通信网络和无线局域网络(Wireless Local Area Networks，WLAN)，其中，蜂窝通信网络为调度主导，WLAN为竞争主导。前述的2G、3G和4G网络，均为蜂窝通信网络。本领域技术人员应知，随着技术的发展本发明实施例提供的技术方案同样可以应用于其他的无线通信网络，例如4.5G或者5G网络，或其他非蜂窝通信网络。为了简洁，本发明实施例有时会将无线通信网络为网络。
机器类通信：是指通过无线网络进行数据传输的机器与机器之间的通信。
终端：是一种主要用于接收或者发送业务数据终端设备，可以是可移动的终端设备，也可以是不可移动的终端设备；可以是MTC场景下的终端设备，也可以是传统通信场景下的终端设备。终端可分布于网络中，在不同的网络中终端有不同的名称，例如：移动台，用户单元，站台，蜂窝电话，无线调制解调器，无线通信设备，会话发起协议(SIP)电话、智能电话、无线本地环路(WLL)站、个人数字助理(PDA)、膝上型计算机、手持式通信设备、卫星无线设备等。终端可以经无线接入网(Radio Access Network，RAN)(无线通信网络的接入部分)与一个或多个核心网进行通信。终端可以用于一个或多个终端进行通信(比如D2D通信)，也可以用于与一个或多个基站进行通信。终端还可以包括系统、用户站、移动站、移动无线终端、节点、远程站、远程终端、无线通信装置或用户代理的功能中的一些或者所有功能。
基站(Base Station，BS)：是一种部署在无线接入网用以提供无线通信功能的装置。例如在2G网络中提供基站功能的设备包括基地无线收发站(Base Transceiver Station，BTS)和基站控制器(Base Station Controller，BSC)，3G网络中提供基站功能的设备包括节点B(NodeB)和无线网络控制器(Radio Network Controller，RNC)，在4G网络中提供基站功能的设备包括演进的节点B(Evolved NodeB，eNB)，在WLAN中，提供基站功能的设备为接入点(Access Point，AP)。基站可以用于与一个或多个 终端进行通信，也可以用于与一个或多个具有部分终端功能的基站进行通信(比如宏基站与微基站，如接入点之间的通信)。基站可以通过空中接口与无线终端进行通信。该通信可以通过一个或多个扇区来进行。基站还可以通过将所接收的空中接口帧转换成IP分组，来用作无线终端和接入网络的其余部分之间的路由器，其中接入网络包括互联网协议(IP)网络。另外，基站还可以对空中接口属性的管理进行协调，并且还可以是有线网络和无线网络之间的网关。
寻呼：在需要建立通信时，基站会通过寻呼信道(Paging Channel，PCH)向终端发起寻呼，寻呼分为核心网发起的寻呼和UTRAN发起的寻呼。

PICH：UMTS网络中用于承载寻呼指示因子的物理信道。
寻呼消息信道：用于承载真正被寻呼的终端的寻呼消息的信道，例如，可以是UMTS网络中的SCCPCH信道。SCCPCH信道中的寻呼消息具体可以包括消息类型(Message Type)，寻呼记录列表(Paging Record List)，寻呼记录(Paging Record)，广播更新信息(BCCH Modification Information)以及预警信息(ETWS Information)等。
SCCPCH：UMTS网络中配置有PCH和前向接入信道(Forward Access Channel，FACH)的从公共控制物理信道。承载PCH信道的SCCPCH信道，一般配置在主频点的时隙0，以便承载小区的寻呼消息。而配置在其他位置(例如业务时隙)的SCCPCH主要是承载FACH信道。本发明实施例中的SCCPCH信道指用于承载寻呼消息的SCCPCH。

在本发明实施例中，“示例的”一词用于表示作例子、例证或说明。本申请中被描述为“示例”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用示例的一词旨在以具体方式呈现概念。
在现有寻呼机制中，由于映射到同一个寻呼指示的终端的数量较多，使得根据寻呼指示进行不必要的寻呼消息信道解调的终端数量也较多，从而导致系统资源开销增大。为了降低寻呼时的系统资源开销，本发明以下实施例提供了一种寻呼指示方法、基站及终端，主要原理为：基站根据至少一个终端的预设参数，利用预设的n(大于1的整数)个映射函数中的每个映射函数，分别将至少一个终端映射到至少两个分组中，因而，与一个映射函数相比，基站通过n个映射函数可以将至少一个终端映射到数量更多的分组中，从而可以减少每个分组中包括的终端的数量。其中，n个映射函数与n个寻呼指示集合一一对应，每个分组中的终端根据预设参数和n个映射函数，确定n个寻呼指示集合中与自身对应的n个寻呼指示的位置，从而确定是否被潜在寻呼，因而可以使得根据n个寻呼指示进行不必要的寻呼消息信道解调的终端的数量，小于现有技术中根据单个寻呼指示进行不必要的寻呼消息信道解调的终端的数量，降低系统资源开销。
本发明实施例提供的寻呼指示方法，具体可以应用于无线通信网络中的基站和终端之间，也可以应用于基站和基站(如宏基站和微基站)之间，还可以应用于终端和终端之间。在本发明以下实施例中，将以基站寻呼终端为例进行详细说明。
具体的，本发明实施例提供的基站和终端的结构示意图可以参见图2。在如图2所示的基站中，寻呼指示和寻呼消息等待发送数据先进入数据处理器，进行分块、编码、交织、加扰等基带操作，再送入调制器进行信号调制，最后通过发射机发射出去；对于接收机接收到的信号，则经历相反的过程，先通过解调器进行解调，再进入接收数据处理器，进行解扰、解交织、解码等操作，得到需要的接收数据；处理器和调制解调器的具体参数和实施步骤都由控制器进行统一控制，控制器还与存储器相连接，进行必要的数据读取。终端侧的结构与基站侧是相互对应的，终端接收基站发送的寻呼指示和寻呼消息，也可以向基站发送其它数据，这里不再赘述。
参见图3，本发明实施例提供一种寻呼指示方法，该方法主要可以包括：
101、基站根据至少一个终端各自的预设参数，利用预设的n个映射函数中的每个映射函数，分别将至少一个终端映射到至少两个分组中，其中，n为大于1的整数，预设参数包括至少一个终端各自的用户标识。
其中，这里的至少一个终端是指基站可以寻呼的位于该基站的覆盖范围内的所有M(大于1的整数)个终端。n的取值为大于1的整数，即预设的映射函数至少为两个，预设映射函数的具体数量可以根据实际需要进行设定。用户标识用于唯一标识一个终端，例如，可以是终端的设备号，IMSI，以及临时移动用户标识(Temporary Mobile Subscriber Identity，TMSI)等。
在本步骤中，基站可以将至少一个终端各自的预设参数作为自变量，利用预设的n个映射函数中的每个映射函数，分别将至少一个终端映射到至少两个分组中。示例性的，以n取2为例，参见图4a，基站可以根据M个终端各自的预设参数，利用预设的第1个映射函数，将M个终端映射到N1(大于1的整数)个分组中，其中，“*”表示的终端1根据第1个映射函数被映射到N1个分组中的分组1中；参见图4b，基站可以根据M个终端各自的预设参数，利用预设的第2个映射函数，将M个终端映射到N2(大于1的整数)个分组中，其中，“*”表示的终端1根据第2个映射函数被映射到N2个分组中的分组1中。
102、基站生成与n个映射函数一一对应的n个寻呼指示集合，其中，每个寻呼指示集合中包括的寻呼指示分别与，由每个寻呼指示集合对应的映射函数所映射的一个分组一一对应，寻呼指示用于指示对应的分组中包括的终端是否被潜在寻呼。
在基站根据n个映射函数将M个终端映射到对应的分组中之后，基站可以生成与n个映射函数一一对应的n个寻呼指示集合，以根据寻呼指示集合中的寻呼指示，指示对应的终端是否被潜在寻呼。举例来说，当寻呼指示为1时，可以指示被潜在寻呼；当寻呼指示为0时，可以指示未被潜在寻呼。
示例性的，以图4a所示映射情况为例，基站可以生成与第1个映射函数对应的寻呼指示集合1
Figure PCTCN2016084207-appb-000002
寻呼指示集合1中包括N1个寻呼指示
Figure PCTCN2016084207-appb-000003
该N1个寻呼指示中的每个寻呼指示与第1个映射函数映射的N1个分组中的一个分组一一对应。参见图5a，p1-1与如图4a所示的分组1对应，用于指示如图4a所示的分组1中包括的所有终端是否被潜在寻呼，其中，p1-1指示是否被潜在寻呼的终端中包括终端1；p1-2与如图4a所示的分组2对应，用于指示如图4a所示的分组2中包括的所有终端是否被潜在寻呼；
Figure PCTCN2016084207-appb-000004
与如图4a所示的分组N1对应，用于指示如图4a所示的分组N1中包括的所有终端是否被潜在寻呼。
以图4b所示映射情况为例，基站可以生成与第2个映射函数对应的寻呼指示集合2
Figure PCTCN2016084207-appb-000005
寻呼指示集合2中包括N2个寻呼指示
Figure PCTCN2016084207-appb-000006
该N2个寻呼指示中的每个寻呼指示与第2个映射函数映射的N2个分组中的一个分组一一对应。参见图5b，p2-1与如图4b所示的分组2对应，用于指示如图4b所示的分组2中包括的所有终端是否被潜在寻呼，其中，p2-1指示是否被潜在寻呼的终端中包括终端1；p2-2与如图4b所示的分组2对应，用于指示如图4b所示的分组2中包括的所有终端是否被潜在寻呼；
Figure PCTCN2016084207-appb-000007
与如图4b所示的分组N2对应，用于指示如图4b所示的分组N2中包括的所有终端是否被潜在寻呼。
可见，基站可以根据终端的预设参数，利用一个映射函数，确定该映射函数对应的寻呼指示集合中，每个终端对应的寻呼指示，即基站可以根据每个映射函数确定每个终端对应的一个寻呼指示的位置，从而可以根据n个映射函数确定每个终端对应的n个寻呼指示的位置。例如，基站根据上述2个映射函数，可以确定终端1对应2个寻呼指示，这2个寻呼指示分别为寻呼指示集合1中的第1个寻呼指示p1-1，和寻呼指示集合2中的第1个寻呼指示p2-1。
也就是说，在本发明实施例中，基站可以根据多个映射关系确定 一个终端对应的多个寻呼指示及多个寻呼指示所在的位置。而在现有技术中，基站仅根据一个映射关系确定一个终端对应的1个寻呼指示及寻呼指示所在的位置。
103、基站通过至少一个信道将n个寻呼指示集合发送给至少一个终端。
在生成n个寻呼指示集合后，基站可以通过至少一个信道将该n个寻呼指示集合发送给M个终端，以使得M个终端中的每个终端可以根据接收到的寻呼指示中的指示信息，确定是否被潜在寻呼。
104、终端接收基站通过至少一个信道发送的n个寻呼指示集合。
与步骤103对应，M个终端中的每个终端，都可以接收基站通过至少一个信道发送的n个寻呼指示集合。
105、终端根据预设参数和预设的n个映射函数，分别从n个寻呼指示集合的每个寻呼指示集合中，确定与终端对应的寻呼指示，预设的n个映射函数与n个寻呼指示集合一一对应，预设参数包括终端的用户标识。
其中，关于用户标识的说明可以参见上述步骤101中的具体描述。预设的n个映射函数与n个寻呼指示集合一一对应，终端在接收到基站发送的n个寻呼指示集合后，可以根据预设参数和预设的n个映射函数，分别从接收到的n个寻呼指示集合的每个寻呼指示集合中，确定与自身对应的寻呼指示。
并且，在预设的n个映射函数中，每个映射函数对应的寻呼指示集合中的寻呼指示，分别与该映射函数对应的分组一一对应，终端属于其中一个分组，寻呼指示用于指示对应分组中包括的终端是否被潜在寻呼。
其中，终端根据预设参数和每个映射函数，确定映射函数对应的寻呼指示集合中终端对应的寻呼指示，即终端可以根据每个映射函数确定一个寻呼指示的位置，从而根据n个映射函数确定n个寻呼指示的位置。
也就是说，在本发明实施例中，终端根据多个映射关系确定多个寻呼指示及所在的位置；而现有技术中，终端仅根据一个映射关系确定一个寻呼指示及所在的位置。
示例性的，以图4a-5b所示情况中的终端1为例，在接收到基站发送的2个寻呼指示集合后，终端1可以根据预设参数，从与第1个映射函数对应的寻呼指示集合1中，确定与终端1对应的寻呼指示为p1-1。p1-1用于指示根据第1个映射函数映射的N1个分组中，分组1中的终端是否被潜在寻呼，其中的终端包括终端1。也就是说，终端1对应寻呼指示p1-1，寻呼指示p1-1对应根据第1个映射函数映射的分组1中的所有终端。
在接收到基站发送的2个寻呼指示集合后，终端1还可以根据预设参数，从与第2个映射函数对应的寻呼指示集合2中，确定与终端1对应的寻呼指示为p2-1。p2-1用于指示根据第2个映射函数映射的N2个分组中，分组1中的终端是否被潜在寻呼，其中的终端包括终端1。也就是说，终端1对应寻呼指示p2-1，寻呼指示p2-1对应根据第2个映射函数映射的分组1中的所有终端。
106、终端根据寻呼指示的指示信息，确定终端是否被潜在寻呼。
终端根据分别从n个寻呼指示集合的每个寻呼指示集合中，确定的与终端对应的寻呼指示的指示信息，确定终端是否被潜在寻呼。
示例性的，以上述终端1为例，终端1可以根据从上述2个寻呼指示集合中确定的，与终端1对应的寻呼指示p2-1和p2-1的指示信息，确定终端是否被潜在寻呼。其中，p1-1和p2-1的指示信息包括指示被潜在寻呼，或指示未被潜在寻呼。
进一步地，结合图5a和图5b可以得到图5c。由图5c可知，M个终端被2个映射函数映射被映射为N1×N2个分组，每个分组对应一个如图5c斜线填充部分所示的小方格，每个小方格对应2个寻呼指示，每个小方格中的终端根据对应的2个寻呼指示的指示信息确定是否被潜在寻呼。以斜线填充的小方格为例，其对应的2个寻呼指示为p1-1 和p2-1。
由图5a可知，M个终端被第1个映射函数映射到N1个分组中，每个分组对应1个寻呼指示；由图5b可知，M个终端被第2个映射函数映射到N2个分组中，每个分组对应1个寻呼指示；由图5c可知，M个终端被2个映射函数映射到N1×N2个分组中，每个分组对应一组寻呼指示，每组寻呼指示具体包括2个寻呼指示。可见，与单个映射函数相比，M个终端可以被2个映射函数映射到更多的分组中，每个分组中包括的终端的数量更少，并且每个分组对应2个寻呼指示。
而现有技术其实相当于，根据一个映射函数将M个终端映射到至少一个分组中，且每个分组对应一个寻呼指示，具体类似于图5a或图5b所示的情况。
举例来说，若M为3240，3240个终端被第1个映射函数映射为18个分组，每个分组对应图5a中的一个竖条区域，每个分组中包括180个终端。3240个终端在被第2个映射函数映射为9个分组，每个分组对应图5b中的一个横条区域，每个分组中包括360个终端。3240个终端被上述2个映射函数映射为18×9＝162个分组，每个分组对应图5c所示的一个小方格，每个分组中包括20个终端。其中的20小于180，也小于360。
实际上，当n取大于1的任何整数时，与单个映射函数相比，M个终端可以通过n个映射函数的n次映射，最终被映射到数量更多的分组中，从而减少了每个分组中包括的终端的数量，且每个分组对应n个寻呼指示。
在本发明实施例提供的寻呼指示方法中，基站根据至少一个终端的预设参数，利用预设的n(大于1的整数)个映射函数中的每个映射函数，分别将至少一个终端映射到至少两个分组中，因而，与一个映射函数相比，基站通过n个映射函数可以将至少一个终端映射到数量更多的分组中，从而可以减少每个分组中包括的终端的数量。其中，n个映射函数与n个寻呼指示集合一一对应，每个分组中的终端根据预设参数和n个映射函数， 确定n个寻呼指示集合中与自身对应的n个寻呼指示及寻呼指示所在的位置，从而确定是否被潜在寻呼，因而可以使得根据n个寻呼指示进行不必要的寻呼消息信道解调的终端的数量，小于现有技术中根据单个寻呼指示进行不必要的寻呼消息信道解调的终端的数量，降低系统资源开销。
在本发明实施例中，预设的n个映射函数可以相互正交。参见图6，在上述步骤101中，基站利用预设的n个映射函数中的每个映射函数，分别将至少一个终端映射到至少两个分组中具体可以包括：
1011、基站通过第i个映射函数将至少一个终端映射到Ni个分组中。
1012、基站通过第i+1个映射函数分别将第i个映射函数对应的Ni个分组中，每个分组包括的终端映射到Ni+1个分组中。
其中，i依次取[1,n)范围内的整数，Ni为大于1的整数，Ni+1为大于1的整数。
根据步骤1011和1012可知，当预设的n个映射函数相互正交时，基站可以通过第i+1个映射函数分别将第i个映射函数对应的Ni个分组中，每个分组包括的终端映射到Ni+1个分组中，从而使得M个终端最终被n个映射函数映射为
Figure PCTCN2016084207-appb-000008
个分组，且不同分组中包括的终端没有重叠部分。
需要说明的是，当n个映射函数不是相互正交时，M个终端可能被n个映射函数映射到R个分组，其中，R小于或者等于S，且不同分组中包括的终端有重叠部分，从而使得重叠部分的终端需要在所在的每个分组分别对应的n个寻呼指示指示被潜在寻呼时，解调寻呼消息信道，从而导致了不必要的寻呼消息信道解调，浪费了资源开销。因而，当预设的n个映射函数相互正交时，可以进一步减少进行不必要的寻呼消息信道解调的终端的数量，节省资源开销。
此外，步骤101中的预设参数还可以包括寻呼时刻发送的无线帧 的系统帧号(System Frame Number，SFN)，以及每个映射函数分别对应的分组的数量。具体的，终端可以采用非连续接收(Discontinuous Reception，DRX)寻呼机制，在与基站约定的特定寻呼时刻(Paging Occasion)接收寻呼指示集合。其中，寻呼时刻的确定方式可以参照如下式1：
Paging Occasion＝{(IMSI/k)mod(DRX cycle/PBP)}×PBP+n×DRX cycle+Frame Offset                       式1
其中，“mod”为求余运算符，“/”为去余求商运算符。式1中的k表示基站发送的，承载寻呼消息的寻呼消息信道的数量。式1中的DRX cycle表示非连续接收周期，具体的，在核心网(Core Network，CN)中，DRX cycle在电路交换(Circuit Switched，CS)域可以通过系统信息广播参数配置；DRX cycle在分组交换(Packet Switch，PS)域可以通过终端与CN进行协商确定，若未协商则可以通过系统信息广播参数配置。在UTRAN连接态下，DRX cycle由基站确定。式1中的PBP表示寻呼块周期(Paging Block Periodicity)，n为非负整数，Frame Offset表示帧偏移，具体取值可以为s帧，其中s为非负整数。例如，在频分双工(Frequency Division Duplexing，FDD)场景下，PBP可以为1，Frame Offset可以为0。
可选地，当终端的用户标识为终端的IMSI时，在n为2的情况下，第1个映射函数可以为：
Figure PCTCN2016084207-appb-000009
第2个映射函数可以为：
Figure PCTCN2016084207-appb-000010
其中，“PI”为(IMSI/8192)mod N1，“/”为去余求商运算符，“mod”为求余运算符，N1表示第1个映射函数对应的分组的数量，N2表示第2个映射函数对应的分组的数量。
需要说明的是，上述映射函数只是在预设参数包括终端的用户标识，SFN，每个映射函数分别对应的分组的数量，且用户标识为终端的IMSI时的示例。本领域技术人员应当知道，预设参数还可以包括其它参数，标识终端的用户标识也可以有很多，本领域技术人员具体可以根据不同类型的参数，设定不同的映射函数，从而根据设定的映射函数将终端映射到多个分组中。因此，上述公式不应对本发明的映射函数构成限定。
上述式2和式3所示的第1个映射函数和第2个映射函数相互正交，M个终端可以被上述2个映射函数映射为N1×N2个分组，且不同分组中包括的终端不会相互重叠。
具体的，基站可以根据M个终端中任一终端的IMSI，寻呼时刻发送的无线帧的系统帧号SFN，以及第1个映射函数对应的映射分组的数量N1，将该终端映射到第t个分组中。终端根据第1个映射函数确定的寻呼指示的位置为寻呼指示集合1中的第t个寻呼指示。其中，t的值根据上述式2进行计算，即：
Figure PCTCN2016084207-appb-000011
基站可以根据该终端的IMSI，寻呼时刻发送的无线帧的系统帧号SFN，第1个映射函数对应的映射分组的数量N1，以及第2个映射函数对应的映射分组的数量N2，将该终端映射到第p个分组中。终端根据第2个映射函数确定的寻呼指示的位置为寻呼指示集合2中的第p个寻呼指示。其中，p的值根据上述式3进行计算，即：
Figure PCTCN2016084207-appb-000012
在上述步骤103中，基站发送n个寻呼指示集合所使用的“至少一个信道”的数量，具体可以为1个，也可以为多个(大于1个)。
其中，当该“至少一个信道”为1信道时，该信道上将承载n个寻呼指示集合。
当该“至少一个信道”的数量为多个时，每个信道分别承载n个寻呼指示集合中的至少一个寻呼指示集合，例如，当该“至少一个信道”为n个信道时，每个信道上将承载1个寻呼指示集合。不同信道上承载的寻呼指示集合可以以码分形式进行发送，即不同信道上承载的寻呼指示集合中的寻呼指示，可以采用不同的码资源(例如采用不同的码序列)。
可选地，当基站通过多个信道分别发送n个寻呼指示集合中的第一个寻呼指示集合时，第一个寻呼指示集合在多个信道上的起始发送时刻可以保持同步。
示例性的，参见图7，当n为2，且基站通过2个信道发送这2个寻呼指示集合时，信道1上可以发送寻呼指示集合1，信道2上可以发送寻呼指示集合2，并且信道1上发送寻呼指示集合1的起始发送时刻，和信道2上发送寻呼指示集合2的起始发送时刻保持同步。这样，可以尽量减小终端通过信道1和信道2分别接收寻呼指示集合1和寻呼指示集合2之间的时间间隔，从而减少终端检测这2个信道上的两个寻呼指示集合中，与自身对应的两个寻呼指示的最大时间间隔，降低检测时间，提高处理效率。
当多个信道中的每个信道中承载多个寻呼指示集合时，基站通过多个信道中的每个信道，分别发送的n个寻呼指示集合中的第一个寻呼指示集合的起始发送时刻可以保持同步。
当然，n个寻呼指示集合中，在不同信道上分别发送的第一个寻呼指示集合的起始发送时刻也可以不保持时间同步，这里不予具体限定。
此外，可选地，在上述“至少一个信道”中，任一信道承载n个寻呼指示集合中的至少一个寻呼指示集合，至少一个寻呼指示集合在任一信道上以寻呼指示集合为单位分段排列。
示例性的，当基站通过信道1发送寻呼指示集合1

和寻呼指示集合2
Figure PCTCN2016084207-appb-000014
时，这2个寻呼指示集合在信道1 上，可以以寻呼指示集合为单位分段排列。参见图8a，具体可以在信道1上先排列完整的寻呼指示集合1，再排列完整的寻呼指示集合2；当然，也可以在信道1上先排列寻呼指示集合2，再排列寻呼指示集合1。
或者，可选地，在上述“至少一个信道”中，任一信道承载n个寻呼指示集合中的至少一个寻呼指示集合，多个寻呼指示集合中不同寻呼指示集合中的寻呼指示在任一信道中交叉排列。
示例性的，当基站通过信道1发送寻呼指示集合1

Figure PCTCN2016084207-appb-000016
且N1大于N2时，这2个寻呼指示集合中的寻呼指示在信道1上可以交叉排列。参见图8b，具体可以在信道1上将2个寻呼指示集合中的寻呼指示排列为：

这样，终端可以从信道1上接收到交叉排列的这些寻呼指示，从而可以减少终端检测两个寻呼指示集合中，与自身对应的两个寻呼指示的最小时间间隔，降低检测时间，提高处理效率。
参见图9，在上述步骤106中，终端根据寻呼指示的指示信息，确定终端是否被潜在寻呼具体可以包括：
若n个寻呼指示集合的每个寻呼指示集合中，与终端对应的寻呼指示均指示被潜在寻呼，则终端确定终端被潜在寻呼；若n个寻呼指示集合的任一寻呼指示集合中，与终端对应的寻呼指示指示未被潜在寻呼，则终端确定终端未被潜在寻呼。
也就是说，只有当n个寻呼指示集合中，与终端对应的n个寻呼指示的指示信息都指示被潜在寻呼时，终端才能确定被潜在寻呼；当与终端对应的n个寻呼指示中，有一个或几个寻呼指示的指示信息指示未被潜在寻呼时，终端确定未被潜在寻呼。
具体的，终端可以逐一检测接收到的寻呼指示集合中，与自身对应的寻呼指示是否指示被潜在寻呼，若指示未被潜在寻呼，则可以停 止检测下一寻呼指示集合中与自身对应的寻呼指示，并确定终端未被潜在寻呼；若指示被潜在寻呼，则可以继续检测下一寻呼指示集合中与自身对应的寻呼指示，直至确定接收到的第n个寻呼指示集合中，与自身对应的寻呼指示也指示被潜在寻呼，则可以确定终端被潜在寻呼。
进一步地，参见图10，在上述步骤103之后，该寻呼指示方法还可以包括：
107、基站通过至少一个寻呼消息信道向至少一个终端发送寻呼消息。
在上述步骤106之后，该寻呼指示方法还可以包括：
108、若终端确定被潜在寻呼，则解调对应的寻呼消息信道。
基站在在发送n个寻呼指示集合之后，可以通过k(大于1的整数，例如为16)个寻呼消息信道，以广播的方式向M个终端发送寻呼消息，以使得真正被寻呼的终端可以通过解调寻呼消息信道获得相应的寻呼消息。当终端确定被潜在寻呼时，可以解调对应的寻呼消息信道，从而确定是否真正被寻呼，并在真正被寻呼时执行相应的响应操作。其中，终端与寻呼消息信道的对应关系可以为：
q＝IMSI mod k                    式4
上述式4中，“mod”表示求余运算符，k表示基站使用的寻呼消息信道的数量，q表示终端对应的寻呼消息信道在k个寻呼消息信道中的位置，即终端与k个寻呼消息信道中的第q个寻呼消息信道相对应。
需要说明的是，虽然n的取值越大，M个终端被n个映射函数映射到的分组的数量就越多，每个分组中包括的终端的数量就越少，但由于基站可以发送k个寻呼消息信道，而且每个寻呼消息信道上可以承载小于或者等于8个终端对应的寻呼消息，即基站可以真正寻呼一定数量的终端，因而n的取值也不是越大越好，具体可以根据实际需 要进行设定。
本发明另一实施例提供一种基站1100，参见图11，该基站1100可以包括：
处理器1101，可以用于根据至少一个终端各自的预设参数，利用预设的n个映射函数中的每个映射函数，分别将至少一个终端映射到至少两个分组中，其中，n为大于1的整数，预设参数包括至少一个终端各自的用户标识。
处理器1101还可以用于，生成与n个映射函数一一对应的n个寻呼指示集合，其中，每个寻呼指示集合中包括的寻呼指示分别与，由每个寻呼指示集合对应的映射函数所映射的一个分组一一对应，寻呼指示用于指示对应的分组中包括的终端是否被潜在寻呼。
发射机1102，可以用于通过至少一个信道将n个寻呼指示集合发送给至少一个终端。
其中，这里的处理器1101可以是通信处理器、调制解调器Modem或者基带处理器，或者是包括应用处理器、图形处理器在内的片上系统(System on Chip，SOC)，处理器核心可以采用ARM提供的处理器核，或者Intel提供的处理器核，或者其它处理器核心。处理器1101还可以进一步包括硬件芯片。上述硬件芯片可以是专用集成电路(Application-specific Integrated Circuit，ASIC)，可编程逻辑器件(Programmable Logic Device，PLD)或其组合。上述PLD可以是复杂可编程逻辑器件(Complex Programmable Logic Device，CPLD)，现场可编程逻辑门阵列(Field-programmable Gate Array，FPGA)，通用阵列逻辑(Generic Array Logic,GAL)或其任意组合。
此外，基站1100还可以包括接收机、存储器和调制器和解调器，具体可以参见图2中所示的基站结构示意图。其中，调制器可以用于对发射信号进行调制，解调器可以用于对接收信号进行解调。存储器可以包括易失性存储器(Volatile Memory)，例如随机存取存储器(Random-access  Memory，RAM)；存储器也可以包括非易失性存储器(Non-volatile Memory)，例如快闪存储器(Flash Memory)，硬盘(Hard Disk Drive，HDD)或固态硬盘(Solid-state Drive，SSD)；存储器还可以包括上述种类的存储器的组合。
具体的，预设的n个映射函数可以相互正交，处理器1101用于利用预设的n个映射函数中的每个映射函数，分别将至少一个终端映射到至少两个分组中具体可以包括：
通过第i个映射函数将至少一个终端映射到Ni个分组中；通过第i+1个映射函数分别将第i个映射函数对应的Ni个分组中，每个分组包括的终端映射到Ni+1个分组中；其中，i依次取[1,n)范围内的整数，Ni为大于1的整数，Ni+1为大于1的整数。
