图 1以举例的方式显示了本发明一个实施例中的一种通信系统的示意图。 图 2以举例的方式显示了本发明一个实施例中的一种寻呼的方法示意图。 图 3以举例的方式显示了本发明又一个实施例中的一种寻呼的方法示意 图。
图 4以举例的方式显示了本发明又一个实施例中的一种寻呼的方法示意 图。
图 5以举例的方式显示了一种基站子系统的单元示意图。
图 6以举例的方式显示了本发明又一个实施例中一种寻呼的方法示意图。 图 7以举例的方式显示了本发明又一个实施例中一种寻呼的方法示意图。 图 8以举例的方式显示了本发明又一个实施例中一种寻呼的方法示意图。 图 9以举例的方式显示了一种终端的单元示意图。 具体实施方式
图 1以举例的方式显示了本发明一个实施例中的一种通信系统 100。 通信 系统 100中包括了 MSC ( Mobile Switching Centre, 移动交换中心) 102、 SGSN ( Serving GPRS Support Node, 服务 GPRS支持节点) 104、 BSC ( Base Station Controller, 基站控制器) 106、 BTS ( Base Transceiver Station, 基站收发信台) 108和终端 110、 112。 其中, BSC和 BTS组成 BSS ( Base Station Subsystem, 基 站子系统) 。 通信系统 100可以为例如使用 GSM ( Global System for Mobile Communications, 全球移动通信系统 )技术的通信系统或者使用 M2M技术的 通信系统。
终端 110和终端 112位于同一个小区中。终端 112位于 BTS 108所下属的小区 Celll内, 终端 110也位于 BTS108所下属的小区 Celll内。 终端 110和终端 112属 于一个群组中。
当 MSC 102或者 SGSN104需要对终端 112和终端 110所在的群组进行寻呼 时, MSC102或者 SGSN104可以向 BSC106发送消息, 由 BSC106发送寻呼命令 给 BTS108, 通过 BTS108对终端 112和终端 110所在的群组进行寻呼。 BTS108 对终端寻呼的消息在寻呼子信道上发送。例如, BTS108与终端 112之间的寻呼 子信道可以位于小区的某个 CCCH信道(Common Control Channel, 公共控制 信道)上,该 CCCH信道对应一个 CCCH信道分组号。终端 112为了接收 BTS108 发送的寻呼的消息, 终端 112侦听其所属的 CCCH信道分组。 一个 CCCH信道 包含一个或者多个寻呼子信道, 因此, 终端 112可以侦听 CCCH信道分组的 CCCH信道上的某个寻呼子信道。 一个 CCCH信道上一个或者多个寻呼子信道 可以用不同的寻呼子信道号码来区分。 在通信系统 100中, 釆用将不同群组的 终端分配给不同的寻呼子信道来进行寻呼。 由于终端 112和终端 110属于同一 个群组, 所以, BTS108通过在一个寻呼子信道上发送带群组的标识信息, 实 现对终端 112和终端 110在同一个寻呼子信道进行寻呼终端 112和终端 110所属 群组中的所有终端都在该寻呼子信道上监听 BTS发送寻呼消息。
因此, 网络为了对终端 112和终端 110所属群组的终端进行寻呼, 可以在 该群组所属的寻呼子信道上对该群组进行寻呼, 而不用对该群组中的所有终 端分别进行寻呼或者在所有寻呼子信道上进行寻呼, 提高了寻呼效率, 减少 了资源消耗。
本发明的一个实施例中以举例的方式提供了一种寻呼的方法。 如图 2所 示, 该方法包括如下部分。
150、 接收终端所在群组的标识信息。
150中可以是基站子系统接收终端所在群组的标识信息。
终端所在群组的标识信息可以由 MSC发送, 也可以由 SGSN发送。 例如, 当被寻呼的群组中的终端在 MSC的服务区内时, MSC向基站子系统发送终端 所在群组的标识信息。
终端的群组的标识信息可以通过寻呼(Paging )消息携带。 当然, 终端所 在群组的标识信息也可以通过其他的消息来携带, 例如, 可以通过新的消息 来携带终端所在群组的标识信息
160、 根据群组的标识信息, 确定该群组的标识信息所对应的公共控制信 道的寻呼子信道。
在本实施例中, 可以通过将多个终端分成不同的群组, 每个群组通过相 应的群组的标识信息来标识。 并且, 每个群组标识信息对应于公共控制信道 上的一个寻呼子信道。 在本发明的另一实施例中, 基站子系统可以保存或者 通过其他方式, 例如从 HLR ( Home Location Register, 归属位置寄存器)或者 MSC ( Mobile Switching Centre, 移动交换中心)接收获取, 获取群组的标识 信息和其对应的公共控制信道的寻呼子信道之间的对应关系, 从而基站子系 统可以确定群组的标识信息对应的寻呼子信道。
170、 在该寻呼子信道上发送第一寻呼请求消息, 该第一寻呼请求消息包 括该群组的标识信息。
为了发送寻呼给该终端所在的群组, 可以在该群组所在的寻呼子信道上 发送第一寻呼请求消息, 通过第一寻呼请求消息中携带群组的标识信息, 监 视该寻呼子信道的终端可以接收到第一寻呼请求消息, 从而可以得知该第一 寻呼请求消息为对群组的寻呼。
本实施例中, 可以根据接收到的群组的标识信息, 在该群组的标识信息 所对应的寻呼子信道上发送第一寻呼请求消息, 从而向该群组的终端进行寻 呼, 从而避免了网络需要对该群组中的所有终端分别进行寻呼或者在所有寻 呼子信道上进行寻呼, 提高了寻呼效率, 减少了资源消耗。
本发明的一个实施例中以举例的方式提供了一种寻呼的方法。 如图 3所 示, 该方法包括如下部分。
210、 接收终端所在群组的标识信息。
例如, 可以^ ^站子系统接收第一消息。
该第一消息可以是 MSC发送的, 也可以由 SGSN发送的。 例如, 当被寻呼 的群组中的终端在 MSC的服务区内时, MSC向基站子系统发送终端所在群组 的标识信息。 终端所在群组的标识信息可以通过寻呼(Paging )消息。 寻呼消 息携带该终端的群组的标识信息。
220、 根据群组的标识信息, 确定群组的标识信息所对应的公共控制信道 的分组号。
确定群组的标识信息所对应的公共控制信道的分组号可以有多种方式。 例如, 基站子系统可以获得公共控制信道的物理信道数。 基站子系统还可以 进一步获得预先设置的取模值以及寻呼块数目, 该取模值可以为最大终端群 组数目, 该取模值也可以为位于最大终端群组数目与零值之间的某一个值。
例如, 根据第一消息中终端所在群组的标识信息、 预先设置的取模值、 公共控制信道的物理信道数目以及寻呼块数目, 可以确定第一消息中终端所 在群组的标识信息所对应的公共控制信道的分组号 NTS
例如, 可以釆用如下公式来确定公共控制信道的分组号:
NTS = ((GroupID mod PresetModValue) mod (BS—CC— CHANS x N)) div N 其中, GroupID代表群组的标识信息所对应的群组标识, mod代表进行模 运算, PresetModValue为预先设置的取模值, 例如 PresetModValue可以预先设 置为 1000, BS—CC— CHANS代表通用控制信道的物理信道的数目, N为寻呼块 的数目, X代表乘法运算, div代表进行整数除法运算。
例如, 根据第一消息中终端所在群组的标识信息和公共控制信道的物理 信道数, 可以确定所述公共控制信道的分组号。
例如, 也可以釆用如下公式来确定公共控制信道的分组号: NTS = GroupID mod BS—CC— CHANS
其中, GroupID代表群组的标识信息所对应的群组标识, mod代表进行模 运算, BS—CC— CHANS代表通用控制信道的物理信道的数目。
分组号和时隙号之间具有对应关系。
230、根据群组的标识信息,确定群组的标识信息所对应的寻呼分组号码。 寻呼分组号码即对应公共控制信道的寻呼子信道。 在 220中确定的公共控 制信道中存在一个或者多个寻呼子信道。 当公共控制信道中存在多个寻呼子 信道时, 可以釆用将多个寻呼子信道进行分组, 每个分组可以称为寻呼分组, 并且, 同一个群组的终端对应一个寻呼分组。
确定群组的标识信息所对应的寻呼分组号码可以有多种方式。 根据第一 消息中终端所在群组的标识信息和寻呼块数目, 确定寻呼分组号码。 或者, 根据第一消息中终端所在群组的标识信息、 预先设置的取模值、 公共控制信 道的物理信道数和寻呼块数目, 确定寻呼分组号码。
例如, 可以釆用如下公式来确定寻呼分组号码 Nch:
Nch = ((GroupID mod PresetModValue) mod (BS—CC— CHANS x N)) mod (N x Multiple)
其中, GroupID代表群组的标识信息所对应的群组标识, mod代表进行模 运算, PresetModValue为预先设置的取模值, 例如 PresetModValue可以预先设 置为 1000 , X代表乘法运算, BS—CC— CHANS代表通用控制信道的物理信道 的数目, N为寻呼块的数目, Multiple代表某个倍数, 如 1、 2、 1000、 10000 等。
也可以釆用如下公式来确定寻呼分组号码 Nch:
Nch = GroupID mod (N x Multiple)
其中, GroupID代表群组的标识信息所对应的群组标识, mod代表进行模 运算, N为寻呼块的数目, Multiple代表某个倍数, 如 1、 2、 1000、 10000等。
可以理解的是, 群组的标识信息用于标识终端所在的群组, 存在许多种 方式来代表群组的标识信息。 例如, 群组的标识信息可以由 MCC ( Mobile Country Code, 移动国家号 码)、 MNC( Mobile Network Code,移动网号 W。GPIN( Group Identity Number, 群组识别号码)组成, 其中, MCC可以由 3位数字组成, 唯一地识别移动用户 所属的国家。 MNC可以由两位数字组成, 用于识别移动用户所归属的移动网。 GPIN可以是一个十位的等长号码 , 例如 H1H2H3H4H5H6H7H8H9H10。
还例如, 群组的标识信息也可以仅仅由上述 GPIN组成。 或者, 群组的标 识信息也可以由上述 GPIN信息中的部分信息组成, 例如 H1H2H3、 H8H9H10 或 H3H4H5H6。
240、 在该寻呼子信道上发送第一寻呼请求消息, 第一寻呼请求消息包括 该群组的标识信息。
为了发送寻呼给群组所在的终端, 可以在第一寻呼请求消息中包含群组 的标识信息。
第一寻呼请求消息携带群组的标识信息有多种方式。
例如, 群组的标识信息可以携带在第一寻呼请求消息的移动标识信元 1 ( Mobile Identity 1 ) 中, 来指示终端该寻呼请求消息为对群组的寻呼请求。
再例如, 群组的标识信息也可以携带在第一寻呼请求消息的 P1其它字节 ( PI Rest Octets )信元中, 同时将移动标识信元 1 ( Mobile Identity 1 ) 的值设 置为指示终端该寻呼请求消息为对群组的寻呼请求 (例如, 可以设置为 No Identity ) 。
再例如, 还可以在第一寻呼请求消息中新设置一个信元, 该信元用来携 带群组的标识信息(例如, Group Identity ), 同时, 将移动标识信元 1 ( Mobile Identity 1 ) 的值设置为指示终端该寻呼请求消息为对群组的寻呼请求 (例如, 可以设置为 No Identity ) 。
通过在第一寻呼请求消息中携带群组的标识信息可以指示终端是针对群 组的寻呼, 同时通过群组的标识信息, 可以防止监听同一个寻呼子信道上的 不同群组的终端都响应该寻呼消息。
第一寻呼请求消息也可以通过国际移动用户群组标识信息来携带群组的 标识信息。 国际移动用户群组标识信息的格式可以釆用类似于 IMSI信息的格 式。国际移动用户群组标识信息可以包括移动国家代码( Mobile Country Code, MCC ) 、 移动网络代码(Mobile Network Code, MNC )和移动用户识别号码 ( Mobile Subscriber Identification Number, MSIN ) 。 国际移动用户群组标识 信息的格式与 IMSI信息的格式不同的是: 将 IMSI信息中移动用户识别号码部 分的信息釆用改由 MSIN— 1和 Group ID两部分组成。 MSIN 1为终端在所在群组 的序号, Group ID为终端的群组号。 MSIN— 1和 Group ID两部分合起来组成终 端的 MSIN, 应保证 MSIN在网内的唯一性。 例如, 如果将 MSIN— 1部分全置为 零, 可以作为代表对 MSIN中的 Group ID所对应的群组的寻呼的一种方式。 例 如, 国际移动用户群组标识信息可以携带在第一寻呼请求消息的移动标识信 元 1 ( Mobile Identity 1 ) 中。 例如, 群组的标识信息部分可以用 3个比特位或 者更少的比特位来表示。 以 MSIN为 9位来举例: 如果群组的标识信息所对应 的群组标识为 "149" , 则 MSIN为 "000000149" 。
在本发明的另一实施例中, 通过将群组的标识信息封装为类似于 IMSI的 格式, 可以不对现有的寻呼消息的格式进行改变, 因此, 对现有网络的改动 较低, 现有的终端也能识别该寻呼消息。
在本发明的另一实施例中, 群组的标识信息还可以由临时群组标识信息 来携带。 临时群组标识信息可以是网络临时给每个群组分配的标识号, 其格 式可以釆用类似于临时移动用户识别号码 ( Temporary Mobile Subscriber Identify, TMSI )信息的格式或者包临时移动用户识别号码( Packet Temporary Mobile Subscriber Identify, P-TMSI )信息的格式, 用于识别群组, 能对应到 具体的群组标识。
基站子系统通过公共控制信道的分组号对应的时隙号可以确定所使用的 公共控制信道的时隙, 通过寻呼子信道号码可以确定发送给终端的寻呼应该 在公共控制信道上的时隙上的那个寻呼子信道上发送。
本实施例中, 基站子系统可以根据接收到群组的标识信息, 在该群组所 对应的寻呼子信道上发送第一寻呼请求消息, 从而向该群组的终端进行寻呼, 信道上进行寻呼, 提高了寻呼效率, 减少了资源消耗。
在本发明的另一个实施例以举例的方式所提供的一种寻呼的方法中, 在 图 2所示的实施例的基础上, 如图 4所示, 还进一步包括如下部分。
250、 接收该终端的终端身份标识信息。
终端身份标识信息用于唯一的标识所述群组标识信息所对应的群组中的 一个终端。 例如, 终端身份标识信息可以为终端的国际移动用户标识 ( International Mobile Subscriber Identity, IMSI )信息、 临时移动用户识别号 码( Temporary Mobile Subscriber Identify , TMSI )或者包临时移动用户识别 号码 ( Packet Temporary Mobile Subscriber Identify, P-TMSI )信息。
260、 根据该终端身份标识信息, 确定该终端所在群组的标识信息。
例如, 基站子系统可以依据终端身份标识信息向 HLR ( Home Location Register 归属位置寄存器)、 VLR ( Visitor Location Register访问位置寄存器) 或其它的网络设备发送查询请求, HLR或 VLR或其它网络设备可以返回相应 终端所在的群组的群组标识信息。
可选的, 也可以将终端的终端身份标识信息与该终端所在群组的标识信 息之间的对应关系保存在基站子系统。 基站子系统通过接收到的终端身份标 识信息向其本身查询该终端所在群组的标识信息。
270、 发送第二寻呼请求消息, 该第二寻呼请求消息包括该终端身份标识 信息。
在本实施例中, 根据接收到终端的终端身份标识信息, 可以在该终端所 在的群组的寻呼子信道上对该终端进行寻呼, 从而可以实现在寻呼子信道上 既可以对群组进行寻呼也可以对该群组中的单个终端进行寻呼。 同时, 由于 目前网络对群组中单个终端的寻呼釆用的是在该终端的 IMSI信息所对应的寻 呼信道上对该终端进行寻呼, 终端为了接收该寻呼, 需要监听该 IMSI信息所 对应的寻呼信道。 釆用了本实施例中的方法, 由于在一个寻呼子信道上可以 实现对群组的寻呼, 也可以实现对群组中单个终端的寻呼, 基站子系统可以 不用在终端的 IMSI信息所对应的寻呼信道上对终端进行寻呼, 相应的, 终端 可以不监听 IMSI信息所对应的寻呼信道, 而只需要监听该终端所在群组的寻 呼子信道。 所以, 可以减少终端监听的寻呼信道的数目, 进一步达到终端省 电的目的, 网络也可以进一步提高寻呼效率, 减少资源消耗。
如图 5所示, 本发明的一个实施例中以举例的方式显示了一种基站子系统 300, 基站子系统可以包括基站和基站控制器。 该基站子系统 300可以完成上 述方法实施例中基站子系统的全部功能。 该基站子系统 300可以釆用软件和 / 或者硬件的方式来实现上述基站子系统的全部功能, 例如, 基站子系统 300可 以包括一个或者多个处理器来实现上述基站子系统的全部功能。 例如, 基站 子系统 300可以包括接收单元 310、 寻呼子信道确定单元 330和发送单元 340。 本领域普通技术人员可以理解的是, 基站子系统 300中单元的划分仅仅为虚拟 单元的划分。

384、 终端监听该寻呼子信道, 确定该终端是否被寻呼。
在公共控制信道上, 一个分组号所对应的时隙号上的时隙可能存在多个 寻呼子信道。 但是, 终端可以只监听寻呼分组号码所对应的寻呼子信道。 该 寻呼子信道可以用于寻呼该终端所在的群组, 也可以用于仅仅寻呼该终端。 终端通过监听该寻呼子信道可以知道该终端是否被寻呼。 确定终端是否被寻 呼可以理解为确定是否该终端所在的群组是否被寻呼, 也可以理解为确定是 否仅仅该终端被寻呼。

430、 终端监听该寻呼子信道, 确定所述终端是否被寻呼。
在公共控制信道上, 一个分组号所对应的时隙号上的时隙可能存在多个 寻呼子信道。 但是, 终端可以只监听寻呼分组号码所对应的寻呼子信道。 该 寻呼子信道可以用于寻呼该终端所在的群组, 也可以用于仅仅寻呼该终端。
确定终端是否被寻呼可以理解为确定是否该终端所在的群组是否被寻 呼, 也可以理解为确定是否仅仅该终端被寻呼。
440、 终端在所述寻呼子信道上接收寻呼请求消息, 所述寻呼请求消息包 含群组的标识信息和终端身份标识信息中的一种。
寻呼请求消息可以由基站子系统发送, 也可以由其他的网络设备发送。 同时, 寻呼请求消息中携带群组的标识信息的方式可以有多种。 例如, 寻呼请求消息中的群组标识信息可以由国际移动用户群组标识信息来携带, 也可以由临时群组标识信息来携带。 临时群组标识信息可以是网络临时给每 个群组分配的标识号, 其格式可以釆用类似于临时移动用户识别号码 ( Temporary Mobile Subscriber Identify , TMSI )信息的格式或者包临时移动 用户识别号码 ( Packet Temporary Mobile Subscriber Identify, P-TMSI )信息 的格式, 用于识别群组, 能对应到具体的群组标识。
可选的, 寻呼请求消息中也可以包含终端身份标识信息, 例如终端的 IMSL TMSI或者 P-TMSI信息, 从而网络可以实现对群组中单个终端的寻呼。
450、 终端确定所述寻呼请求消息中的群组的标识信息对应的群组标识是 否与所述终端所在群组的标识信息对应的群组标识相同, 或者, 终端确定所 述寻呼请求消息中的终端身份标识信息是否与所述终端的终端身份标识信息 相同。
460、 对应所述终端确定所述寻呼请求消息中的群组的标识信息对应的群 组标识是否与所述终端所在群组的标识信息对应的群组标识相同或者对应所 述终端确定所述寻呼请求消息中的终端身份标识信息是否与所述终端的终端 身份标识信息相同, 所述终端确定是否发送消息以响应所述寻呼请求消息。 本实施例中, 终端通过确定其群组标识信息的所对应的寻呼子信道, 终 端可以监视该寻呼子信道上网络发送的针对该终端的寻呼的消息, 并确定是 否需要对该消息作出响应, 从而终端只需要监视该寻呼子信道, 避免了终端 需要监视所有的寻呼子信道, 减少了资源消耗, 终端可以达到了省电的功能。

终端获取群组的标识信息的方式可以有多种。 例如, 群组的标识信息可 以为终端从网络预先接收到保存在本地的。
520、 终端确定群组的标识信息所对应的公共控制信道的分组号。
终端确定群组的标识信息所对应的公共控制信道的分组号可以有多种方 式。 例如, 终端可以获得公共控制信道的物理信道数。 终端还可以获得预先 设置的取模值以及寻呼块数目, 该取模值可以为最大终端群组数目, 该取模 值也可以为位于最大终端群组数目与零值之间的某一个值。 由于获取该 3个参 数的手段都是已知的现有手段, 因此, 不在进行累述。 相应的, 根据终端所 在群组的标识信息和公共控制信道的物理信道数, 终端可以确定所述公共控 制信道的分组号。 或者, 根据终端所在群组的标识信息、 预先设置的取模值、 公共控制信道的物理信道数目以及寻呼块数目, 终端可以确定群组的标识信 息所对应的公共控制信道的分组号 NTS
例如, 终端可以釆用如下公式来确定 NTS:
NTS = ((群组的标识信息 mod MaxGroupNum) mod (BS_CC_CHANS x N)) div N
其中, mod代表进行模运算, MaxGroupNum为预先设置的最大群组数目, 例如 MaxGroupNum可以预先设置为 1000, BS—CC— CHANS代表通用控制信道 的物理信道的数目, N为寻呼块的数目, div代表进行整数除法运算。 530、 终端确定群组的标识信息所对应的公共控制信道的寻呼分组号码。 终端确定群组的标识信息所对应的寻呼分组号码可以有多种方式。 例如, 终端可以釆用如下公式来确定寻呼分组号码 Nch:
Nch = ((群组的标识信息 mod PresetModValue) mod (BS_CC_CHANS x
N)) mod N
其中, mod代表进行模运算, PresetModValue为预先设置的取模值, 例 如 PresetModValue可以预先设置为 1000, BS— CC— CHANS代表通用控制信道的 物理信道的数目, N为寻呼块的数目。
535、 终端在公共控制信道的分组号所对应的时隙号上监听寻呼分组号码 对应的寻呼子信道, 确定该终端是否被寻呼。

540、 终端在寻呼子信道号码对应的寻呼子信道上接收寻呼请求消息, 所 述寻呼请求消息包含群组的标识信息和终端身份标识信息中的一种。
寻呼请求消息可以由基站子系统发送, 也可以由其他的网络设备发送。 同时, 寻呼请求消息中携带群组的标识信息的方式可以有多种。 例如, 寻呼请求消息中的群组标识信息可以由国际移动用户群组标识信息来携带, 也可以由临时群组标识信息来携带。 临时群组标识信息可以是网络临时给每 个群组分配的标识号, 其格式可以釆用类似于临时移动用户识别号码 ( Temporary Mobile Subscriber Identify , TMSI )信息的格式或者包临时移动 用户识别号码 ( Packet Temporary Mobile Subscriber Identify, P-TMSI )信息 的格式, 用于识别群组, 能对应到具体的群组标识。
可选的, 寻呼请求消息中也可以包含终端身份标识信息, 例如终端的 IMSL TMSI或者 P-TMSI信息, 从而网络可以实现对群组中单个终端的寻呼。
550、 终端确定寻呼请求消息中的群组的标识信息对应的群组标识是否与 终端所在群组的标识信息对应的群组标识相同, 或者终端确定寻呼请求消息 中的终端身份标识信息是否与终端的终端身份标识信息相同。
如果寻呼请求消息中包含的是群组的标识信息, 终端可以通过确定接收 到的寻呼请求消息中的群组标识是否和该终端的群组标识相同, 以此来确定 该寻呼请求消息是否是针对该终端的寻呼。
如果寻呼请求消息中包含的是终端身份标识信息, 终端可以通过确定寻 呼请求消息中的终端身份标识信息是否与终端的终端身份标识信息相同, 以 此来确定该寻呼请求消息是否是针对该终端的寻呼。
560、 对应终端确定所述寻呼请求消息中的群组的标识信息对应的群组标 识是否与该终端所在群组的标识信息对应的群组标识相同或者对应终端确定 寻呼请求消息中的终端身份标识信息是否与该终端的终端身份标识信息相 同, 该终端确定是否发送消息以响应寻呼请求消息。
如果终端确定寻呼请求消息中的群组标识和其自身的群组标识相同或者 终端确定寻呼请求消息中的终端身份标识信息与该终端的终端身份标识信息 相同, 终端确定接收到的寻呼请求消息为针对其自身的寻呼, 终端可以决定 响应接收到的寻呼请求消息。
如果终端确定寻呼请求消息中的群组标识和其自身的群组标识不相同或 者终端确定寻呼请求消息中的终端身份标识信息与该终端的终端身份标识信 息不相同, 终端确定接收到的寻呼请求消息不是针对其自身的寻呼, 终端可 以不响应接收到的寻呼请求消息。
本实施例中, 终端通过确定其群组标识信息所对应的寻呼子信道, 终端 可以监视该寻呼子信道上网络发送的针对该终端的寻呼的消息, 并确定是否 需要对该消息作出响应, 从而终端只需要监视其群组标识信息所对应的寻呼 子信道, 避免了终端需要监视所有的寻呼子信道, 减少了资源消耗, 终端可 以达到了省电的功能。
