Description

一种寻呼方法、寻呼设备、核心网设备、基站和寻呼系统 技术领域
本发明涉及通信技术领域,尤其涉及一种寻呼方法、寻呼设备、核心网设备、基站和寻呼系统。
背景技术
在目前的通信系统中,当核心网有下行数据需要发送给用户设备(英文:User Equipment;缩写:UE)时,核心网设备启动寻呼定时器,并向寻呼区内的所有基站发送携带UE标识的寻呼消息。
寻呼区内的基站在接收到该寻呼消息时,根据该寻呼消息中携带的UE标识,计算该UE标识对应的UE在空口上的最近一个寻呼时刻,并在该寻呼时刻到来时,将该寻呼消息发送给该UE标识对应的UE。
该UE标识对应的UE在接收到寻呼消息时,向核心网设备发送寻呼响应消息,这样核心网设备在接收到寻呼响应消息时,关闭寻呼定时器。
由于UE只能在寻呼时刻才能接收寻呼消息,而UE的寻呼时刻是周期出现的。以UE在全球移动通信系统(英文:Global System for Mobile communication;缩写:GSM)中为例,UE的寻呼时刻对应一系列的时分多址接入(英文:Time Division Multiple Access;缩写:TDMA)帧号,这些TDMA帧号可以根据UE的国际移动用户标识符(英文:International Mobile Subscriber Identifier;缩写:IMSI)计算得到。例如:计算得到的TDMA帧号为0帧号、100帧号、200帧号、300帧号、400帧号、……。也就是说,UE的寻呼时刻分别出现在0帧号上、在100帧号上、在200帧号上、在300帧号上、在400帧号上、……。又由于TDMA帧号不可能是无限的,假设TDMA帧号的上限为1000,那么UE的寻呼时刻分别出现在0帧号上、在100帧号上、在200帧号上、在300帧号上、在400帧号上、在500帧号上、在600帧号上、在700帧号上、在800帧号上、在900帧号上以及在1000帧号上, 循环往复。
那么基站在接收到该寻呼消息时,根据该寻呼消息中携带的UE标识,计算该UE标识对应的UE在空口上的最近一个寻呼时刻,具体包括:
基站根据该寻呼消息中携带的UE标识,计算出该UE标识对应的UE的寻呼时刻,并根据当前时刻对应的无线帧号以及计算出的该UE标识对应的UE的寻呼时刻,确定出最接近当前时刻对应的无线帧号的寻呼时刻作为该UE标识对应的UE在空口上的最近一个寻呼时刻。
仍以上述事例为例进行说明。例如:当前时刻对应的无线帧号为108,计算出的该UE标识对应的UE的寻呼时刻包含0帧号、100帧号、200帧号、300帧号、400帧号、500帧号、600帧号、700帧号、800帧号、900帧号和1000帧号,那么得到的该UE标识对应的UE在空口上的最近一个寻呼时刻为200帧号,也就是说,在200帧到达时,基站将接收到得寻呼消息发送给UE。
在实际应用中,核心网设备在发送寻呼消息时启动寻呼定时器,等待UE发送的寻呼响应消息,但是当寻呼定时器超时时,核心网设备依然尚未接收到UE发送的寻呼响应消息,此时,核心网设备只能重新发送寻呼消息。
这样,核心网设备在寻呼过程中,不仅寻呼定时器的作用被大大减弱,而且浪费核心网与基站之间的接口资源,还使得核心网设备执行寻呼的效率大大降低。

具体实施方式
为了实现本发明的目的,本发明实施例提供了一种寻呼方法、寻呼设备、核心网设备、基站和寻呼系统,通过核心网设备向寻呼区内的至少一个基站发送寻呼消息,所述寻呼消息中包含被所述核心网设备寻呼的用户设备UE的标识;并接收至少一个所述基站发送的响应消息,所述响应消息中包含发送该响应消息的所述基站根据所述UE的标识确定的与所述UE的寻呼时刻相关联的时间信息,所述寻呼时刻为所述UE接收所述寻呼消息的时刻;根据所述响应消息中包含的时间信息,确定寻呼定时器的定时时长,并启动所述寻呼定时器。这样核心网设备能够准确获取与所述UE的寻呼时刻相关联的时间信息,使核心网能够合理配置寻呼定时器的定时时长,有效地保证在寻呼定时器超时之前寻呼消息能够发送给UE,大大提升了寻呼定时器在寻呼时的作用,同时避免核心网设备重复发送寻呼消息,提升核心网设备执行寻呼的效率,并节省了空口资源。
本发明实施例中所述的寻呼时刻可以是无线帧号,也可以是具体的时间点,还可以是其他形式,这里不做限定。
下面结合说明书附图对本发明各个实施例作进一步地详细描述。显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例,都属于本发明保护的范围。
如图1所示,为本发明提供的一种寻呼方法的流程示意图。所述方法可以如下所述。
步骤101:核心网设备向寻呼区内的至少一个基站发送寻呼消息。
其中,所述寻呼消息中包含被所述核心网设备寻呼的UE的标识。
在步骤101中,核心网设备在有下行数据需要发送给UE时,向其寻呼区内的基站发送寻呼消息。
所谓寻呼区是指一个地理区域,核心网设备向该地理区域内的基站发送寻呼消息。例如:在GSM系统中,这里所说的寻呼区可以对应于路由区(英文:Routing Area),或者对应于位置区(英文:Location Area);在长期演进(英文:Long Term Evolution;缩写:LTE)系统中,这里所说的寻呼区还可以对应于跟踪区(英文:Tracking Area)。
通常一个寻呼区内可能有一个基站或者多个基站,每一个基站内又包含多个服务小区。一般地,UE在不同服务小区内的寻呼时刻存在差异,也就是说,确定的UE在服务小区1内的寻呼时刻与确定的UE在服务小区2内的寻呼时刻不同。
步骤102:寻呼区内的基站接收所述核心网设备发送的寻呼消息,并根据所述寻呼消息中包含的UE标识,确定与所述UE的寻呼时刻相关联的时间信息,并将确定的所述时间信息携带在响应消息中发送给所述核心网设备。
在步骤102中,以寻呼区内的一个基站为例说明基站根据所述寻呼消息中包含的UE标识,确定与所述UE的寻呼时刻相关联的时间信息的具体实现方式,不同基站确定时间信息的实现方式相似,这里不再做赘述。
具体地,第一种实现方式:
所述基站根据所述UE的标识,确定所述UE即将到来的最近一次的寻呼时刻。
需要说明的是,若基站包含多个服务小区,那么所述基站将针对每一个服务小区确定所述UE即将到来的最近一次的寻呼时刻。例如:假设基站包含服务小区1、服务小区2和服务小区3,确定所述UE在服务小区1内即将到 来的最近一次的寻呼时刻T1;确定所述UE在服务小区2内即将到来的最近一次的寻呼时刻T2;确定所述UE在服务小区3内即将到来的最近一次的寻呼时刻T3。也就是说,一个基站确定所述UE即将到来的最近一次的寻呼时刻可以是一个,也可以是多个,这里不做限定。
第二种实现方式:
所述基站根据所述UE的标识,确定所述UE即将到来的最近一次的寻呼时刻与所述基站接收到所述寻呼消息的时刻之间的相对差值。
具体地,所述基站根据所述UE的标识,确定所述UE即将到来的最近一次的寻呼时刻,并计算所述UE即将到来的最近一次的寻呼时刻与所述基站接收到所述寻呼消息的时刻之间的相对差值。
例如:所述基站根据所述UE的标识,确定所述UE即将到来的最近一次的寻呼时刻为T1,而所述基站接收到所述寻呼消息的时刻为t,那么计算得到的相对差值为T1与t之间差的绝对值。也就是说,相对于所述基站接收到所述寻呼消息的时刻,还需要(T1-t)时长到达UE的寻呼时刻。
这里需要说明的是,若确定的所述UE即将到来的最近一次的寻呼时刻为多个时,那么计算得到的相对差值的个数也不限于1个。
第三种实现方式:
所述基站根据所述UE的标识,确定所述UE即将到来的最近一次的寻呼时刻与所述基站接收到所述寻呼消息的时刻之间的相对差值区间。
具体地,所述基站根据所述UE的标识,确定所述UE即将到来的最近一次的寻呼时刻,并计算所述UE即将到来的最近一次的寻呼时刻与所述基站接收到所述寻呼消息的时刻之间的相对差值;所述基站根据计算得到的相对差值,确定该相对差值对应的相对差值区间。也就是说,相对于所述基站接收到所述寻呼消息的时刻,还需要经过相对差值区间对应的时长到达UE的寻呼时刻。
例如:预先配置相对差值与相对差值区间之间的对应关系,所述基站根据所述对应关系和计算得到的相对差值,确定该相对差值对应的相对差值区 间。
再例如:预先配置相对差值t1与相对差值区间【x秒,y秒】对应,当所述基站计算得到t1时,确定相对差值区间【x秒,y秒】。也就是说,相对于所述基站接收到所述寻呼消息的时刻,还需要经过【x秒,y秒】到达UE的寻呼时刻。
这里需要说明的是,基站在向核心网发送响应消息时,该响应消息中可以包含确定的相对差值区间,还可以包含该相对差值区间对应的序号,由于核心网设备可以根据序号与相对差值区间之间的对应关系,确定接收到得响应消息中包含的序号对应的相对差值区间。
第四种实现方式:
所述基站根据所述UE的标识,确定所述UE的寻呼周期。
这里的寻呼周期用于表征所述UE相邻两次接收到寻呼消息之间的时间差。
具体地,所述基站根据所述UE的标识,确定所述UE的寻呼时刻,并根据确定的所述UE的寻呼时刻,计算得到所述UE的寻呼周期。
例如:确定所述UE的寻呼时刻出现在0帧号上、在100帧号上、在200帧号上、在300帧号上、在400帧号上、在500帧号上、在600帧号上、在700帧号上、在800帧号上、在900帧号上以及在1000帧号上,那么计算得到所述UE的寻呼周期为100帧,也就是说,每经过100帧到达UE的一个寻呼时刻。
第五种实现方式:
所述基站根据所述UE的标识,确定所述UE的寻呼周期和所述基站确定的所述UE即将接入的小区的第一当前时刻。
例如:计算得到所述UE的寻呼周期为100帧,也就是说,每经过100帧到达UE的一个寻呼时刻,而所述基站确定的所述UE即将接入的小区的第一当前时刻为108帧。
步骤103:所述核心网设备接收至少一个所述基站发送的响应消息。
其中,所述响应消息中包含发送该响应消息的所述基站根据所述UE的标识确定的与所述UE的寻呼时刻相关联的时间信息,所述寻呼时刻为所述UE接收所述寻呼消息的时刻。
在步骤103中,所述核心网设备接收至少一个所述基站发送的响应消息,所述响应消息中包含发送该响应消息的所述基站根据所述UE的标识确定的与所述UE的寻呼时刻相关联的时间信息可以是通过步骤102中记载的五种实现方式中的任意一种实现方式得到,这里不做具体描述。
步骤104:所述核心网设备根据接收到的所述响应消息中包含的时间信息,确定寻呼定时器的定时时长,并启动所述寻呼定时器。
在步骤104中,若所述响应消息中包含的时间信息包括所述UE即将到来的最近一次的寻呼时刻,则所述核心网设备确定寻呼定时器的定时时长,具体包括:
所述核心网设备计算所述UE即将到来的最近一次的寻呼时刻与当前时刻之间的相对差值;
所述核心网设备根据计算得到的最大的相对差值,确定寻呼定时器的定时时长。
需要说明的是,若计算得到的相对差值的个数为一个,那么将计算得到的相对差值视为最大的相对差值;若计算得到的相对差值的个数为至少两个,那么将从计算得到的相对差值中选择出数值最大的,作为最大的相对差值。
可选地,若所述响应消息中包含的时间信息包括所述UE即将到来的最近一次的寻呼时刻与发送该响应消息的所述基站接收到所述寻呼消息的时刻之间的相对差值,则所述核心网设备确定寻呼定时器的定时时长,具体包括:
所述核心网设备根据接收到的所述响应消息中包含的相对差值,确定最大的相对差值;
所述核心网设备根据所述最大的相对差值,确定寻呼定时器的定时时长。
需要说明的是,若接收到的相对差值的个数为一个,那么将接收到的相对差值视为最大的相对差值;若接收到的相对差值的个数为至少两个,那么 将从接收到的相对差值中选择出数值最大的,作为最大的相对差值。
可选地,若所述响应消息中包含的时间信息包括所述UE即将到来的最近一次的寻呼时刻与发送该响应消息的所述基站接收到所述寻呼消息的时刻之间的相对差值区间,则所述核心网设备确定寻呼定时器的定时时长,具体包括:
所述核心网设备根据接收到的所述响应消息中包含的相对差值区间,确定所述相对差值区间中最大的相对差值;
所述核心网设备根据所述最大的相对差值,确定寻呼定时器的定时时长。
需要说明的是,若接收到的相对差值区间的个数为一个,那么利用接收到的相对差值区间中的最大的相对差值确定寻呼定时器的定时时长;若接收到的相对差值区间的个数为至少两个,那么将从接收到的相对差值区间中选择出数值最大的相对差值,并利用选择出的最大的相对差值,确定寻呼定时器的定时时长。
具体地,上述记载的所述核心网设备根据最大的相对差值,确定寻呼定时器的定时时长,具体包括:
所述核心网设备将所述最大的相对差值确定为寻呼定时器的定时时长;
