可见,在本实施例中,终端设备可以在省电模式与连接态之间直接转换,且当从连接态进入到省电模式时,终端设备会保留在连接态时接入层的配置。这样当终端设备在省电模式发送传输时,终端设备可以直接从省电模式直接返回到连接态,并在连接态直接发起传输。而现有技术中需要从省电模式先进入到空闲态,然后在空闲态进入RRC连接态后再进行传输发起接入,比较而言,在本发明实施例中,由于从连接态发起传输时的流程会比较少,具体可以通过保留的RRC连接和Iu口的连接直接发起数据传输或信令传输,从而节省了从空闲态发起传输时的RRC连接建立,NAS信令连接,鉴权,安全认证和PDP激活等过程,降低了终端设备的耗能。

本发明设备实施例一
提供一种终端设备,结构示意图如图1所示,包括:
参数获取单元10,用于获取所述终端设备从连接态进入省电模式的第一时间信息,及所述终端设备从所述省电模式返回连接态的第二时间信息。其中,连接态可以包括如下任一种状态:小区(CELL)专用信道(Dedicated Channel,DCH)状态,以下简称为CELL_DCH状态;小区向前接入信道(Forward Access Channel,FACH)状态,以下简称为CELL_FACH状态;小区寻呼信道状态,以下简称为CELL_PCH状态;通用陆地无线接入网(Universal Terrestrial Radio Access Network,UTRAN)登记区(registration area)寻呼信道状态,以下简称为URA_PCH状态。
在具体实现过程中,该参数获取单元10,具体用于向网络设备发送请求消息,所述请求消息用于请求所述网络设备配置所述第一时间信息和/或第二时间信息;接收所述网络设备返回的响应消息,所述响应消息中包括所述第一时间信息和/或第二时间信息;所述网络设备为所述终端设备所在网络的接入网设备,或核心网设备,其中接入网设备是该终端设备接入网络使用的接入网中部署的设备,可以为基站或无线网络控制器等,而核心网设备是核心网中部署的设备,可以为通用无线分组业务支撑节点(Serving General Packer Radio Service Support Node,SGSN)等设备。
状态转换单元11,用于根据所述参数获取单元10获取的第一时间信息,从连接态转换到省电模式,根据所述参数获取单元10获取的第二时间信息, 从所述省电模式转换到所述连接态,实现了终端设备在连接态与省电模式之间的直接转换。
省电模式单元12,用于当所述状态转换单元11将终端设备转换到所述省电模式下,保留所述终端设备在所述连接态时接入层(Access Stratum,AS)的配置。其中,省电模式单元12保留的所述终端设备在所述连接态时接入层的配置,主要可以包括:无线资源控制连接等连接的信息,进一步地,该接入层的配置还可以包括:分组数据协议激活信息,鉴权信息,安全认证信息,及所述终端设备所在网络的接入网设备与核心网设备之间的接口信息等。且接入层的配置还可以包括:终端设备在连接态时启动的任何一个定时器的信息等。
传输发起单元13,用于当所述状态转换单元11将所述终端设备从所述省电模式返回所述连接态,根据省电模式单元12保留的所述接入层的配置发起传输。
需要说明的是,在一个具体的实施例中,上述参数获取单元10具体获取的第一时间信息和第二时间信息分别为第一预置时间和第二预置时间,其中第一预置时间为终端设备进入连接态至终端设备离开连接态而进入省电模式的时间段;第二预置时间为终端设备进入连接态至终端设备从连接态进入省电模式后再离开省电模式而重新进入连接态的时间段,或第二预置时间是终端设备进入省电模式至终端设备离开该省电模式而进入连接态的时间段;则状态转换单元11,具体用于当所述终端设备进入所述连接态的时间超过第一预置时间,且没有上下行数据时,进入省电模式;当所述终端设备进入所述省电模式的时间或所述终端设备进入所述连接态的时间点到当前时刻的时间超过第二预置时间时,从所述省电模式返回所述连接态。
在另一个具体的实施例中,在一种情况下,状态转换单元11,还用于当所述终端设备在所述省电模式下有数据传输或信令传输时,不需要等待终端设备进入所述省电模式的时间或所述终端设备进入所述连接态的时间点到当前时刻的时间超过第二预置时间,就从所述省电模式返回所述连接态。在另一种情况下,状态转换单元11,具体用于当所述终端设备在所述省电模式下有信令传输时,需要等待终端设备进入所述省电模式的时间或所述终端设备进入所述连接态的时间点到当前时刻的时间超过第二预置时间,才从所述省电模式返 回所述信道寻呼状态。上述信令传输可以包括:所述终端设备进入所述连接态后的小区更新信令的传输,或所述终端设备不在服务状态后的重连信令的传输等。
需要说明的是,上述的省电模式可以包括第一省电模式或第二省电模式,其中,在第一省电模式下,上述省电模式单元12不仅需要保留接入层的配置,还用于在该第一省电模式下,周期性地监听寻呼信息,则状态转换单元11,还用于当所述终端设备在所述第一省电模式下,且当所述省电模式单元监听的所述寻呼信息指示有数据传输时,从所述第一省电模式转换到所述连接态;在第二省电模式下,上述省电模式单元12,用于在所述第二省电模式下,不监听寻呼信息,但是需要保留接入层的配置,也就是说,且在第二省电模式下,终端设备对于核心网是不可达的,即核心网设备不能连接到或寻呼到该终端设备。
可见,在本实施例的终端设备中,状态转换单元11可以实现终端设备从省电模式直接转换到连接态,且在省电模式下,省电模式单元12会保留终端设备在连接态下接入层的配置,这样传输发起单元13可以在连接态直接发起传输,而现有技术中终端设备需要从省电模式先进入到空闲态,然后在空闲态发起传输,比较而言,在本发明实施例中,由于在连接态发起传输时的流程会比较少,具体可以通过保留的RRC连接直接发送传输,从而节省了从空闲态发起传输时的RRC连接建立,NAS信令连接,鉴权,安全认证和PDP激活等过程,降低了终端设备的耗能,进而达到终端设备节点的目的。
本发明设备实施例二
提供一种接入网设备,比如无线网络控制器(Radio Network Controller,RNC)等,其结构示意图如图2所示,包括:
参数协商单元20,用于确定所述终端设备从连接态进入省电模式的第一时间信息,及所述终端设备从所述省电模式返回连接态的第二时间信息,将所述第一时间信息和/或第二时间信息发送给终端设备。
在一个具体实现的过程中,该参数协商单元20可以在终端设备通过接入网设备连接到网络后,主动确定第一时间信息和第二时间信息后,并发送给终 端设备。
或者,在另一个具体的实施例中,该参数协商单元20需要接收到终端设备发送的第一请求消息,该第一请求消息用于请求接入网设备配置第一时间信息和/或第二时间信息;才会根据第一请求消息,最终确定第一时间信息和第二时间信息,且将最终确定的第一时间信息和/或第二时间信息发送给终端设备。
状态同步单元21,用于根据上述参数协商单元20确定的第一时间信息和第二时间信息,确定所述终端设备的状态,主要是终端设备在连接态与省电模式之间转换的状态。
在一个具体的实施例中,上述参数协商单元20具体确定的第一时间信息和第二时间信息分别为第一预置时间和第二预置时间;则状态同步单元21具体用于当所述终端设备进入连接态的时间超过所述第一预置时间,且没有上下行数据时,确定所述终端设备进入省电模式;当所述终端设备进入所述省电模式的时间或所述终端设备进入所述连接态的时间点到当前时刻的时间超过第二预置时间时,确定所述终端设备从所述省电模式返回所述连接态。
进一步地,如果终端设备在进入所述省电模式的时间或所述终端设备进入所述连接态的时间点到当前时刻的时间未超过第二预置时间时,临时决定从省电模式进入连接态并发起传输时,该状态同步单元21也能根据发起的传输确定终端设备的状态是返回到连接态。
状态操作单元22,用于根据所述状态同步单元21确定的终端设备的状态,当所述终端设备从连接态进入所述省电模式时,保留所述终端设备在所述连接态时接入层的配置;当所述终端设备从所述省电模式返回连接态时,恢复所述接入层的配置的使用。
其中,状态操作单元22保留的所述终端设备在所述连接态时接入层的配置,具体可以包括:无线资源控制连接等连接的信息,且进一步地,该接入层的配置还可以包括:分组数据协议激活信息,鉴权信息,安全认证信息,及所述终端设备所在网络的接入网设备与核心网设备之间的接口信息等。且接入层的配置还可以包括:终端设备在连接态时启动的任何一个定时器的信息等。
需要说明的是,上述终端设备所处的省电模式可以包括第一省电模式或第 二省电模式,则当终端设备处于第一省电模式时,上述状态操作单元22不仅需要保留接入层的配置,且还用于当所述终端设备在所述第一省电模式时,周期性地发送寻呼信息给所述终端设备;当终端设备处于第二省电模式时,上述在状态操作单元22,用于当所述终端设备在所述第二省电模式时,不发送信息给所述终端设备,但需要保留接入层的配置,即在第二省电模式下,终端设备对于网络是不可达的。
可以理解,本实施例中,当上述状态同步单元21确定了终端设备进入上述第二省电模式后,并不会向核心网设备同步该终端设备的状态,则核心网设备还会发送信息给终端设备,当接入网设备接收到核心网设备发给终端设备的信息后,状态操作单元22还可以向核心网设备发送失败消息或不向核心网设备发送任何回复。当上述状态同步单元21确定了终端设备进入上述第一省电模式后,并不会向核心网设备同步该终端设备的状态,则核心网设备还会发送信息给终端设备,当接入网设备接收到核心网设备发给终端设备的信息后,如果终端设备在监听寻呼信息的周期未到来时,状态操作单元22还会向核心网设备发送失败消息或不向核心网设备发送任何回复,如果该周期到来,则状态操作单元22会将寻呼信息发送给终端设备。
可见,本实施例的接入网设备中,通过上述参数协商单元20可以将第一时间信息和第二时间信息预置到终端设备中,使得终端设备可以根据第一时间信息和第二时间信息,在连接态与本实施例中所述的省电模式之间直接转换,在这个过程中,本实施例的接入网设备需要通过状态同步单元21来同步地确定终端设备的状态,且通过状态操作单元22对接入层的配置进行保留和恢复,而接入网设备的其它执行流程可以按照现有流程进行处理,在此不进行赘述,使得可以通过对现有的系统进行较小的改变,即可实现连接态与本实施例中所述的省电模式之间直接转换。
本发明设备实施例三
提供另一种接入网设备,其结构示意图如图3所示,包括:
第一状态同步单元30,用于确定终端设备的状态。
第二状态同步单元31,用于根据所述第一状态同步单元30确定的终端设 备的状态,与核心网设备之间进行所述终端设备的状态同步。
状态处理单元32,用于根据所述第一状态同步单元30确定的终端设备的状态,当所述终端设备从连接态进入所述省电模式时,保留所述终端设备在所述连接态时接入层的配置;当所述终端设备从所述省电模式返回连接态时,恢复所述接入层的配置的使用。
其中,状态处理单元32保留的所述终端设备在所述连接态时接入层的配置,具体可以包括:无线资源控制连接等连接的信息,且进一步地,该接入层的配置还可以包括:分组数据协议激活信息,鉴权信息,安全认证信息,及所述终端设备所在网络的接入网设备与核心网设备之间的接口信息等。且接入层的配置还可以包括:终端设备在连接态时启动的任何一个定时器的信息等。
进一步地,在接入网设备中除了可以包括上述图3所示的结构外,还可以包括参数确定单元,主要用于确定所述终端设备从连接态进入省电模式的第一时间信息,及所述终端设备从所述省电模式返回的连接态第二时间信息。在具体实现过程中,该参数确定单元具体确定的第一时间信息和第二时间信息分别为第一预置时间和第二预置时间;则上述第一状态同步单元30,具体用于当所述终端设备进入连接态的时间超过所述第一预置时间,且没有上下行数据时,确定所述终端设备进入省电模式;当所述终端设备进入所述省电模式的时间或所述终端设备进入所述连接态的时间点到当前时刻的时间超过第二预置时间时,确定所述终端设备从所述省电模式返回所述连接态。
该参数确定单元可以在接收所述终端设备发送的第一请求消息,所述第一请求消息用于请求所述接入网设备配置第一时间信息和/或第二时间信息;还可以向所述终端设备返回的第一响应消息,所述第一响应消息中包括所述第一时间信息和/或第二时间信息;或者,所述该参数确定单元,用于直接接收所述终端设备或核心网设备发送的第一时间信息和/或第二时间信息,所述第一时间信息和/或第二时间信息是由所述核心网设备与所述终端设备之间协商好的。
需要说明的是,上述终端设备所处的省电模式可以包括第一省电模式或第二省电模式,则当终端设备处于第一省电模式时,上述状态处理单元32不仅需要保留接入层的配置,且还用于当所述终端设备在所述第一省电模式时,周 期性地发送寻呼信息给所述终端设备;当终端设备处于第二省电模式时,上述在状态处理单元32,用于当所述终端设备在所述第二省电模式时,不发送信息给所述终端设备,但需要保留接入层的配置,即在第二省电模式下,终端设备对于网络是不可达的。
可见,当终端设备在省电模式与连接态之间直接转换的过程中,本实施例的接入网设备中的第二状态同步单元32需要将终端设备在连接态与省电模式之间转换的状态同步给核心网设备,使得核心网设备知道终端设备在什么时候进入什么状态,则当终端设备在省电模式时,核心网设备就可以不寻呼或发送数据给终端设备,或周期性地寻呼该终端设备,能节省了核心网设备的信令流程。
在具体的实施例中,第一状态同步单元30和第二状态同步单元31具体可以包括如下几种方式的同步:

在这种情况下,接入网设备中的第一状态同步单元30还可以同步地知道终端设备在进入到连接态之后的什么时候进入省电模式,从而如果核心网设备在终端设备处于省电模式时,发送信息给终端设备,如果终端设备是处于第二省电模式,则该接入网设备就可以向核心网设备发送失败消息或不向核心网设备发送任何回复,使得核心网设备发送信息给终端设备时发送失败;如果终端设备是处于第一省电模式,则该接入网设备会周期性地将核心网设备发送的寻呼信息发送给终端设备,该周期与终端设备在第一省电模式时监听寻呼信息的周期一致。
(2)第一状态同步单元30,具体用于确定所述终端设备从连接态进入省 电模式,则第二状态同步单元31,用于在终端设备进入省电模式后,将第一状态信息发送给核心网设备,所述第一状态信息中包括所述终端设备进入所述省电模式的信息。这里第一状态信息中包括的所述终端设备进入所述省电模式的信息是指终端设备当前时刻已经进入省电模式的信息。
进一步地,如果第一状态同步单元30确定终端设备是进入上述第一省电模式,则第二状态同步单元31可以在第一状态信息中还包括终端设备监听寻呼信息的周期信息,使得核心网设备可以根据该周期信息,在终端设备处于第一省电模式时,可以周期性地发送寻呼信息给终端设备;或者第二状态同步单元31只是在第一状态信息中包括终端设备进入第一省电模式的信息,而在核心网设备中已经预置了该周期信息,则核心网设备也可以在终端设备处于第一省电模式时,周期性地发送寻呼信息给终端设备。
(3)第二状态同步单元31,还用于当所述第一状态同步单元30确定所述终端设备从所述连接态进入所述省电模式后,发送第二状态信息给所述核心网设备,所述第二状态信息中包括:所述终端设备离开所述省电模式的信息,这里第二状态信息中包括的信息可以是指终端设备当前时刻已经离开省电模式的信息,也可以是终端设备什么时候离开省电模式的时间信息。
在其中的一种情况下,该第二状态同步单元31,具体用于当所述第一状态确定单元30确定所述终端设备从连接态进入省电模式后,在接收到所述核心网设备发送给所述终端设备的信息时,才会将所述第二状态信息发送给核心网设备,所述第二状态信息中包括的信息是指所述终端设备离开所述省电模式的时间信息。在另一种情况下,该第二状态同步单元31用于当终端设备从连接态进入省电模式后,又从省电模式再返回到连接态时,发送第二状态信息,该第二状态信息中包括的信息是指终端设备已经离开省电模式的信息。
(4)第二状态同步单元31,具体用于当所述第一状态同步单元30确定当所述终端设备离开所述连接态时,将第四状态信息发送给所述核心网设备,所述第四状态信息中包括:所述终端设备离开所述连接态的信息,所述第四状态信息,用于所述核心网设备根据所述第四状态信息,确定所述终端设备从所述连接态进入所述省电模式或进入其它状态,这里第四状态信息中包括的信息是指终端设备当前时刻已经离开连接态的信息。

需要说明的是,上述终端设备所处的省电模式可以包括第一省电模式或第二省电模式,则当终端设备处于第一省电模式时,上述处理单元41不仅需要保留连接的配置,且还可以用于当所述终端设备在所述第一省电模式时,周期性地发送寻呼信息给所述终端设备;当终端设备处于第二省电模式时,上述在处理单元41,用于当所述终端设备在所述第二省电模式时,不发送信息给所述终端设备,但需要保留连接的配置,即在第二省电模式下,终端设备对于网络是不可达的。
可见,当终端设备可以在省电模式与连接态之间直接转换的过程中,核心网设备需要与接入网设备之间进行终端设备的状态的同步,使得核心网设备在终端设备处于省电模式时,不寻呼或不要发送数据给该终端设备,或只是周期性地寻呼该终端设备,这样能节省了核心网设备的信令流程。
在具体的实施例中,同步单元40具体可以包括如下几种方式的同步:

本发明设备实施例五
提供一种终端设备,结构示意图如图5所示,包括分别连接到总线的存储器50、处理器51和收发器52,其中:

处理器51,用于调用存储器50中储存的程序代码,以实现如下功能:
获取所述终端设备从连接态进入省电模式的第一时间信息,及所述终端设备从所述省电模式返回连接态的第二时间信息;根据第一时间信息,从连接态转换到省电模式,保留所述终端设备在所述连接态时接入层的配置;根据所述第二时间信息,从所述省电模式转换到所述连接态,根据保留的所述接入层的配置控制收发器51发起传输。实现了终端设备在连接态与省电模式之间的直接转换。
如果上述第一时间和第二时间分别为第一预置时间和第二预置时间;处理器51,具体用于当所述终端设备进入所述连接态的时间超过第一预置时间且没有上下行数据时,进入省电模式;当所述终端设备进入所述省电模式的时间或所述终端设备进入所述连接态的时间点到当前时刻的时间超过第二预置时间时,从所述省电模式返回所述连接态。
且处理器51在获取上述第一时间信息和第二时间信息时,可以控制收发器52向网络设备发送请求消息,所述请求消息用于请求所述网络设备配置所述第一时间信息和/或第二时间信息;然后由收发器52接收所述网络设备返回的响应消息,所述响应消息中包括所述第一时间信息和/或第二时间信息;所述网络设备为所述终端设备所在网络的接入网设备,或核心网设备。

需要说明的是,上述的省电模式可以包括第一省电模式或第二省电模式,其中,在第一省电模式下,上述处理器51不仅需要保留接入层的配置,还用于在该第一省电模式下,控制收发器52周期性地监听寻呼信息,则当所述寻呼信息指示有数据传输时,从所述第一省电模式转换到所述连接态;在第二省电模式下,上述处理器51不监听寻呼信息,但是需要保留接入层的配置,也就是说,且在第二省电模式下,终端设备对于核心网是不可达的,即核心网设备不能连接到或寻呼到该终端设备。
可见,在本实施例的终端设备中,可以实现终端设备从省电模式直接转换到连接态,且在省电模式下,处理器51会保留终端设备在连接态下接入层的配置,这样处理器51就可以控制收发器52在连接态直接发起传输,而现有技术中终端设备需要从省电模式先进入到空闲态,然后在空闲态发起传输,比较而言,在本发明实施例中,由于从连接态发起传输时的流程会比较少,具体可以通过保留的RRC连接和Iu口的连接直接发送传输,从而节省了从空闲态发起传输时的RRC连接建立,NAS信令连接,鉴权,安全认证和PDP激活等过程,降低了终端设备的耗能,进而达到终端设备节点的目的。

在一个具体实施例中,处理器可以在终端设备通过接入网设备连接到网络后,控制收发器主动将第一时间信息和第二时间信息发送给终端设备。或者,当收发器接收到所述终端设备发送的第一请求消息,所述第一请求消息用于请求所述接入网设备配置所述第一时间信息和/或第二时间信息;才会根据所述第一请求消息,控制收发器将最终确定的第一时间信息和/或第二时间信息发送给终端设备。
其中如果上述第一时间信息和第二时间信息分别为第一预置时间和第二预置时间;则处理器在确定终端设备的状态时,当所述终端设备进入连接态的时间超过所述第一预置时间,且没有上下行数据时,确定所述终端设备进入省电模式;当所述终端设备进入所述省电模式的时间或所述终端设备进入所述连接态的时间点到当前时刻的时间超过第二预置时间时,确定所述终端设备从所述省电模式返回所述连接态。
进一步地,如果终端设备在进入所述省电模式的时间或所述终端设备进入所述连接态的时间点到当前时刻的时间未超过第二预置时间时,临时决定从省电模式进入连接态并发起传输时,处理器也能根据发起的传输确定终端设备的 状态是返回到连接态,
需要说明的是,上述终端设备所处的省电模式可以包括第一省电模式或第二省电模式,则当终端设备处于第一省电模式时,处理器不仅需要保留接入层的配置,且还可以控制收发器周期性地发送寻呼信息给所述终端设备;当终端设备处于第二省电模式时,收发器不发送信息给所述终端设备,但需要处理器保留接入层的配置,即在第二省电模式下,终端设备对于网络是不可达的。
可见,本实施例的接入网设备中,收发器可以将第一时间信息和第二时间信息预置到终端设备中,使得终端设备可以根据第一时间信息和第二时间信息,在连接态与本实施例中所述的省电模式之间直接转换,在这个过程中,本实施例的接入网设备需要同步确定终端设备的状态,且对接入层的配置进行保留和恢复,而接入网设备的其它执行流程可以按照现有流程进行处理,在此不进行赘述,使得可以通过对现有的系统进行较小的改变,即可实现连接态与本实施例中所述的省电模式之间直接转换。
本发明设备实施例七
提供另一种接入网设备,其结构与上述如图5所示的终端设备的结构类似,包括:存储器、处理器和收发器,其中:
存储器用来储存储存处理器处理数据的必要文件等信息,比如储存处理器执行下述方法实施例三或四中所述的终端设备的状态处理方法的程序代码等信息。
处理器,用于调用存储器中储存的程序代码,以实现如下功能:
确定终端设备的状态。根据所述终端设备的状态,与核心网设备之间进行所述终端设备的状态同步。根据所述终端设备的状态,当所述终端设备从连接态进入所述省电模式时,保留所述终端设备在所述连接态时接入层的配置;当所述终端设备从所述省电模式返回连接态时,恢复所述接入层的配置的使用。
其中,保留的所述终端设备在所述连接态时接入层的配置,具体可以包括:无线资源控制连接等连接的信息,进一步地,该接入层的配置还可以包括分组数据协议激活信息,鉴权信息,安全认证信息,及所述终端设备所在网络的接入网设备与核心网设备之间的接口信息等。且接入层的配置还可以包括:终端 设备在连接态时启动的任何一个定时器的信息等。

可见,当终端设备在省电模式与连接态之间直接转换的过程中,本实施例的接入网设备中处理器需要控制收发器将终端设备在连接态与省电模式之间转换的状态同步给核心网设备,使得核心网设备知道在什么时候寻呼或发送数据给该终端设备,使得当终端设备在省电模式时,核心网不要寻呼或发送数据给终端设备,或只是周期性地寻呼该终端设备,能节省了核心网设备的信令流程。

在这种情况下,接入网设备中的处理器还可以同步地知道终端设备在进入到连接态之后的什么时候进入省电模式,从而如果核心网设备在终端设备处于省电模式时,发送信息给终端设备,如果终端设备是处于第二省电模式,则该控制器就可以控制收发器向核心网设备发送失败消息或不向核心网设备发送任何回复,使得核心网设备发送信息给终端设备时发送失败;如果终端设备是 处于第一省电模式,则处理器会周期性地控制收发器将核心网设备发送的寻呼信息发送给终端设备,该周期与终端设备在第一省电模式时监听寻呼信息的周期一致。
(2)处理器具体用于确定所述终端设备从连接态进入省电模式,则控制收发器将第一状态信息发送给核心网设备,所述第一状态信息中包括所述终端设备进入所述省电模式的信息。这里第一状态信息中包括的所述终端设备进入所述省电模式的信息是指终端设备当前时刻已经进入省电模式的信息。
进一步地,如果处理器确定终端设备是进入上述第一省电模式,则可以在第一状态信息中还包括终端设备监听寻呼信息的周期信息,使得核心网设备可以根据该周期信息,在终端设备处于第一省电模式时,可以周期性地发送寻呼信息给终端设备;或者处理器只是在第一状态信息中包括终端设备进入第一省电模式的信息,而在核心网设备中已经预置了该周期信息,则核心网设备也可以在终端设备处于第一省电模式时,周期性地发送寻呼信息给终端设备。
(3)处理器还用于当确定所述终端设备从所述连接态进入所述省电模式后,控制收发器发送第二状态信息给所述核心网设备,所述第二状态信息中包括:所述终端设备离开所述省电模式的信息,这里第二状态信息中包括的信息可以是指终端设备当前时刻已经离开省电模式的信息,也可以是终端设备什么时候离开省电模式的时间信息。
在其中的一种情况下,该处理器具体用于当确定所述终端设备从连接态进入省电模式后,在收发器接收到所述核心网设备发送给所述终端设备的信息时,才会控制收发器将所述第二状态信息发送给核心网设备,所述第二状态信息中包括的信息是指所述终端设备离开所述省电模式的时间信息。在另一种情况下,该处理器用于当终端设备从连接态进入省电模式后,又从省电模式再返回到连接态时,控制收发器发送第二状态信息,该第二状态信息中包括的信息是指终端设备已经离开省电模式的信息。
(4)处理器具体用于当确定所述终端设备离开所述连接态时,控制收发器将第四状态信息发送给所述核心网设备,所述第四状态信息中包括:所述终端设备离开所述连接态的信息,所述第四状态信息,用于所述核心网设备根据所述第四状态信息,确定所述终端设备从所述连接态进入所述省电模式或进入 其它状态,这里第四状态信息中包括的信息是指终端设备当前时刻已经离开连接态的信息。
本发明设备实施例八
提供一种核心网设备,比如SGSN等,其结构与上述如图5所示的终端设备的结构类似,包括:存储器、处理器和收发器,其中:
存储器用来储存储存处理器处理数据的必要文件等信息,比如储存处理器执行下述方法实施例五或六中所述的终端设备的状态处理方法的程序代码等信息。
处理器,用于调用存储器中储存的程序代码,以实现如下功能:
与终端设备所在网络的接入网设备之间进行所述终端设备的状态同步;根据所述终端设备的状态,当所述终端设备从连接态进入所述省电模式时,保留所述终端设备在所述连接态时连接的配置;当所述终端设备从所述省电模式返回连接态时,恢复所述连接的配置的使用。
进一步地,处理器还用于与终端设备之间确定所述终端设备从连接态进入省电模式的第一时间信息,及所述终端设备从所述省电模式返回的连接态第二时间信息。其中,如果该第一时间信息和第二时间信息分别是第一预置时间和第二预置时间,则处理器在同步时,当所述终端设备进入连接态的时间超过所述第一预置时间,且没有上下行数据时,确定所述终端设备进入省电模式;当所述终端设备进入所述省电模式的时间或所述终端设备进入所述连接态的时间点到当前时刻的时间超过第二预置时间时,确定所述终端设备从所述省电模式返回所述连接态。
需要说明的是,上述终端设备所处的省电模式可以包括第一省电模式或第二省电模式,则当终端设备处于第一省电模式时,处理器不仅需要保留连接的配置,且还可以控制收发器周期性地发送寻呼信息给所述终端设备;当终端设备处于第二省电模式时,收发器不发送信息给所述终端设备,但需要处理器保留连接的配置,即在第二省电模式下,终端设备对于网络是不可达的。
可见,当终端设备可以在省电模式与连接态之间直接转换的过程中,核心网设备需要与接入网设备之间进行终端设备的状态的同步,使得核心网设备在 终端设备处于省电模式时,不寻呼或不要发送数据给该终端设备,或只是周期性地寻呼该终端设备,这样能节省了核心网设备的信令流程。
在具体的实施例中,接入网设备具体可以包括如下几种方式的同步:
(1)收发器接收终端设备所在网络的接入网设备发送的第一状态信息,所述第一状态信息中包括所述终端设备进入省电模式的信息。
在本实施例中,如果收发器接收的第一状态信息是指终端设备已经进入上述第二省电模式的信息,则说明终端设备是不可达的,处理器还用于根据所述第一状态信息,控制收发器停止寻呼或停止发送数据给所述终端设备;如果收发器接收的第一状态信息中除了包括终端设备进入省电模式的信息,还包括终端设备监听寻呼信息的周期信息,则说明终端设备进入了上述第一省电模式,收发器还用于根据所述第一状态信息,控制收发器周期性地寻呼该终端设备;如果收发器接收的第一状态信息中的信息指示终端设备进入上述第一省电模式,则处理器还用于根据所述第一状态信息及预置的周期信息,控制收发器周期性地寻呼该终端设备。
(2)收发器用于接收所述接入网设备发送的第三状态信息,所述第三状态信息中包括所述终端设备进入所述连接态的信息,则处理器根据所述第三状态信息,及所述终端设备从所述连接态进入省电模式的第一时间信息,确定所述终端设备什么时候进入省电模式。且根据终端设备从省电模式返回连接态的第二时间信息,确定终端设备什么时候返回连接态。
(3)收发器用于接收所述接入网设备发送的第四状态信息,所述第四状态信息是当所述终端设备离开所述连接态时所述接入网设备发送的,所述第四状态信息中包括:所述终端设备离开所述连接态的信息。
则处理器还用于根据所述收发器接收的第四状态信息,确定所述终端设备从所述连接态进入所述省电模式或其它状态。具体地,如果终端设备进入连接态的时间超过第一预置时间,且没有上下行数据时,则确定终端设备是从连接态进入了省电模式;如果终端设备进入连接态的时间未超过第一预置时间,或超过第一预置时间且有上下行数据时,则确定终端设备是从连接态进入了其它状态,则停止对终端终端设备进入省电模式的时间进行计时,或停止对终端设备进入连接态的时间点到当前时刻的时间进行计时,可以根据该第四状态信息 执行其它状态的操作,比如开始正常寻呼或开始发送数据给终端设备。
(4)收发器用于接收所述接入网设备发送的第二状态信息,所述第二状态信息中包括:所述终端设备离开所述省电模式的信息,其中,所述第二状态信息是所述终端设备从所述连接态进入省电模式后,所述接入网设备发送的。则所述处理器,还用于根据所述第二状态信息,确定终端设备在什么时候离开省电模式。
在其中一种情况下,处理器具体用于如果终端设备从连接态进入省电模式后,控制收发器通过所述接入网设备向所述终端设备发送信息时,收发器才会接收到所述接入网设备发送的所述第二状态信息,所述第二状态信息中包括的信息指示所述终端设备离开所述省电模式的时间信息,则处理器还可以根据该第二状态信息,在确定终端设备离开所述省电模式时,控制收发器开始正常寻呼或开始发送数据给所述终端设备。在另一种情况下,收发器具体用于如果终端设备从连接态进入省电模式后,又从省电模式返回所述连接态时,才会接收到所述接入网设备发送的所述第二状态信息,则第二状态信息中包括的信息指示所述终端设备已经离开所述省电模式。
本发明实施例还提供一种传输发起系统,主要包括终端设备、所述终端设备所在网络的接入网设备和核心网设备,其中:所述终端设备可以是如上述设备实施例五所述的终端设备,接入网设备可以是可以如上述设备实施例七所述的接入网设备,核心网设备的结构可以是如上述设备实施例八所述的核心网设备,在此不进行赘述。
本发明实施例还提供另一种传输发起系统,主要包括终端设备和所述终端设备所在网络的接入网设备,其中,所述终端设备可以是如上述设备实施例五所述的终端设备,接入网设备可以是如上述设备实施例六所述的接入网设备,在此不进行赘述。
本发明方法实施例一
提供一种传输发起方法,主要是应用于终端设备所处的移动网络系统中,在移动网络系统中,终端设备一般都是通过接入网连接到核心网(Core  Network,CN)中,本实施例的方法是由终端设备所执行的方法,流程图如图6所示,包括:
步骤101,获取终端设备从连接态进入省电模式的第一时间信息,及终端设备从省电模式返回连接态的第二时间信息,具体地,终端设备,可以向网络设备发送请求消息,该请求消息用于请求网络设备配置第一时间信息和/或第二时间信息;然后接收网络设备返回的响应消息,该响应消息中包括第一时间信息和/或第二时间信息;其中,网络设备为终端设备所在网络的接入网设备,或核心网设备。
在上述请求消息中可以包括终端设备推荐使用的第一时间信息和/或第二时间信息,如果网络设备接收到请求消息时,根据其中包括的终端设备推荐的第一时间信息和/或第二时间信息,及网络侧的实际情况最终确定第一时间信息和/或第二时间信息。如果最终确定的第一时间信息和第二时间信息中某一个与终端设备推荐使用的不一致,则在上述返回的响应消息中可以包括不一致的第一时间信息和/或第二时间信息。
步骤102,根据上述步骤101获取的第一时间信息,从连接态转换到省电模式,当将终端设备转换到省电模式下,保留终端设备在所述连接态时接入层的配置。具体地,上述第一时间信息可以为第一预置时间,则当终端设备进入连接态的时间超过第一预置时间,且没有上下行数据时,终端设备进入省电模式。
可以理解,当终端设备接入到网络后,终端设备的RRC状态可以包括空闲态(idle Mode)和连接态,在本实施例中,终端设备在接入到网络后的状态还可以包括省电模式。其中,连接态又可以分为如下4种状态:CELL_DCH状态;CELL_FACH状态;ELL_PCH状态;URA_PCH状态。具体地,各种状态的转化示意图如图7所示:
(1)在CELL_DCH状态下,终端设备的上行和下行都分配有一个专用物理信道;根据终端设备当前的活动集可以知道终端设备所在的小区;终端设备可以使用专用传输信道,下行/上行共享传输信道或这些传输信道的组合。
终端设备可以在CELL_FACH状态使用公共传输信道通过信道切换后使用专用传输信道,从而进入到CELL_DCH状态;终端设备在空闲态下将RRC 连接建立在专用信道上,从而使得终端设备进入CELL_DCH状态。终端设备也可以进入到寻呼信道状态。
(2)在CELL_FACH状态下,终端设备未分配有专用传输信道,需要监听一个下行FACH信道;终端设备分配有一个默认的上行公共信道或上行共享传输信道例如RACH;终端设备的位置在小区级为UTRAN所知,具体为终端设备最近一次发起小区更新时报告的小区。
终端设备会执行如下认为任务:监听一个FACH;监听当前服务小区的广播信道(Broadcast Channel,BCH)以解码系统信息;在小区发生改变时发起一个小区更新过程;在随机接入信道(Random Access Channel,RACH)上传送上行控制信令和小数据包。
在CELL_FACH状态下,如果数据业务在一段时间里未被激活,则终端设备将进入CELL_PCH状态以减少功率的损耗,且当终端设备暂时脱离CELL_PCH状态时,执行小区更新。
(3)在CELL_PCH状态下,终端设备没有分配有专用信道;终端设备不能有任何上行的活动;不能使用专用控制信道(Dedicated Control Channel,DCCH)的逻辑信道,如果网络侧试图发起任何活动,需要在终端设备所在小区的PCCH逻辑信道上发送一个寻呼请求;终端设备的位置在小区级为UTRAN所知,具体为终端设备在CELL_FACH状态时最近一次发起小区更新时所报告的小区。
终端设备会执行以下任务:使用非连续接收(Discontinuous Reception,DRX)技术在某个特定的寻呼时刻监听PCH传输信道上的信息,具体地,根据DRX周期监听寻呼时刻并接收PCH上的寻呼消息;监听终端设备当前所在服务小区的BCH以解码系统信息;当终端设备所在小区改变时发起小区更新过程。
终端设备可以通过UTRAN寻呼或通过任何上行接入,从CELL_PCH状态转换到CELL_FACH状态或者CELL_DCH状态。
(4)在URA_PCH状态下与在CELL_PCH状态下的终端设备类似,不同的是,终端设备只有在路由区发生改变(而不是小区改变)时才会发起位置更新过程。网络侧只有终端设备路由区的信息,需要在整个路由区寻呼才能找到 终端设备。
(5)本实施例中的省电模式可以包括第一省电模式或是第二省电模式,在第二省电模式下,终端设备的射频模块关闭,即不能进行上行和下行传输,此时终端设备不会监听寻呼信息,核心网设备不能直接连接或寻呼到该终端设备,但仍然会保持RRC连接以及PDP附着。在第一省电模式下,终端设备不仅需要保留接入层的配置,还需要周期性地监听寻呼信息,当监听的寻呼信息指示有数据传输时,该终端设备可以第一省电模式转换到连接态。
本实施例中,终端设备进入连接态的时间超过第一预置时间,且没有上下行数据时,可以直接进入省电模式,比如第一省电模式或第二省电模式,其中第一预置时间可以是终端设备与接入网设备或与核心网协商得到的。
如果终端设备在这种情况下进入省电模式时,会保留终端设备在连接态时接入层的配置,包括保持RRC连接等连接的信息,且还可以包括Iu口(接入网与核心网之间的连接接口)的信息,鉴权信息,安全认证信息和PDP激活信息等,还可以保持终端设备在连接态时启动的任何一个定时器,比如定时器T305等。其中定时器T305是当终端设备进入连接态时启动的定时器,当该T305超时时,终端设备会进行小区更新操作。
步骤103,根据上述步骤101中获取的第二时间信息,从省电模式转换到连接态,当终端设备从省电模式返回连接态,根据保留的接入层的配置发起传输。终端设备从省电模式返回连接态,之后终端设备可以直接使用在省电模式下保持的RRC连接,且会执行连接态下的任务,比如小区更新(Cell Update,CU),跟踪区更新(Tracking Area Update,TAU)或路由区更新(Routing Area Update,RAU)等。
具体地,上述第二时间信息可以为第二预置时间,则当终端设备进入省电模式的时间或终端设备进入所述连接态的时间点到当前时刻的时间超过第二预置时间时,该终端设备可以从上述省电模式返回到连接态。
在具体实施例中,终端设备会设置两个定时器即定时器T1和T2,在一种情况下,当终端设备进入连接态时,可以同时启动定时器T1和T2;在另一种情况下,当终端设备进入连接态时,启动定时器T1,当终端设备进入省电模式时,启动定时器T2。则在本实施例的方法中,如果该定时器T1超时且没有 上下行数据时,则终端设备从连接态进入省电模式,当定时器T2超时时,终端设备从省电模式返回连接态。
在另一个具体的实施例中,在一种情况下,终端设备在省电模式下有数据传输或信令传输时,可以不需要等待终端设备进入省电模式的时间或终端设备进入连接态的时间点到当前时刻的时间超过第二预置时间,就从省电模式返回信道寻呼状态。在另一种情况下,当终端设备在省电模式下有信令传输时,需要等待终端设备进入省电模式的时间或终端设备进入连接态的时间点到当前时刻的时间超过第二预置时间,才从省电模式返回信道寻呼状态。
其中,信令传输可以包括:终端设备进入连接态后的小区更新信令的传输,具体地,是在终端设备进入连接态时,启动上述的定时器T305,如果终端设备处于省电模式的过程中,该定时器T305才超时,则终端设备需要进行的小区更新信令的传输;
上述信令传输还可以包括:终端设备不在服务状态后的重连信令的传输,这种情况是当终端设备处于省电模式时,搜索不到网络信号,即不在服务状态,则终端设备会启动一个定时器T316,如果该定时器T316超时时,终端设备需要传输的重新连接网络的信令。
可见,在本实施例中,终端设备通过上述步骤102和103实现了终端设备从省电模式直接转换到连接态,且在省电模式下,终端设备会保留在连接态时接入层的配置,这样终端设备可以在连接态直接发起传输,而现有技术中终端设备需要从PSM模式先进入到空闲态,然后在空闲态发起传输,比较而言,在本发明实施例中,由于从连接态发起传输时的流程会比较少,具体可以通过保留的RRC连接和Iu口的连接直接发送传输,从而节省了从空闲态发起传输时的RRC连接建立,NAS信令连接,鉴权,安全认证和PDP激活等过程,降低了终端设备的耗能,进而达到终端设备节点的目的。
本发明方法实施例二
提供一种终端设备的状态处理方法,主要是应用于终端设备所处的移动网络系统中,在移动网络系统中,终端设备一般都是通过接入网连接到核心网中,本实施例的方法是由终端设备所在网络的接入网设备所执行的方法,其中接入 网设备是终端设备所在接入网中部署的设备,比如RNC等,本实施例方法流程图如图8所示,包括:
步骤201,终端设备所在网络的接入网设备确定终端设备从连接态进入省电模式的第一时间信息,及终端设备从省电模式返回连接态的第二时间信息,将所述第一时间信息和/或第二时间信息发送给终端设备。
在一个具体实现的过程中,接入网设备可以在终端设备通过接入网设备连接到网络后,主动确定第一时间信息和第二时间信息后,并发送给终端设备。
或者,在另一个具体的实施例中,接入网设备需要接收到终端设备发送的第一请求消息,该第一请求消息用于请求接入网设备配置第一时间信息和/或第二时间信息;该接入网设备才会根据第一请求消息,最终确定第一时间信息和第二时间信息,且还会将最终确定的第一时间信息和/或第二时间信息发送给终端设备。
步骤202,接入网设备根据上述确定的第一时间信息和第二时间信息,当终端设备在连接态与省电模式之间直接转换时,接入网设备也会根据上述第一时间信息和第二时间信息同步地确定终端设备的状态。
在具体实现过程中,如果上述第一时间信息和第二时间信息分别为第一预置时间和第二预置时间,则当终端设备进入连接态的时间超过第一预置时间,且没有上下行数据时,接入网设备确定终端设备进入省电模式;当终端设备进入所述省电模式的时间或终端设备进入所述连接态的时间点到当前时刻的时间超过第二预置时间时,接入网设备确定所述终端设备从所述省电模式返回所述连接态。
进一步地,如果终端设备在进入所述省电模式的时间或所述终端设备进入所述连接态的时间点到当前时刻的时间未超过第二预置时间时,临时决定从省电模式进入连接态并发起传输时,该接入网设备也能根据发起的传输确定终端设备的状态是返回到连接态。
步骤203,根据上述步骤202确定的终端设备的状态,当终端设备从连接态进入所述省电模式时,保留终端设备在连接态时接入层的配置;当终端设备从省电模式返回连接态时,恢复接入层的配置的使用。
其中,接入网设备保留的终端设备在连接态时接入层的配置,具体可以包 括:无线资源控制连接等连接的信息,进一步地,该接入层的配置还可以包括分组数据协议激活信息,鉴权信息,安全认证信息,及终端设备所在网络的接入网设备与核心网设备之间的接口信息等。且接入层的配置还可以包括:终端设备在连接态时启动的任何一个定时器的信息等。
需要说明的是,上述终端设备所处的省电模式包括第一省电模式或第二省电模式,则接入网设备在终端设备处于第一省电模式时,会周期性地发送寻呼信息给终端设备;接入网设备在终端设备处于第二省电模式时,不发送信息给终端设备。其中,本实施例中,当接入网设备确定了终端设备进入上述第二省电模式后,并不会向核心网设备同步该终端设备的状态,则核心网设备还会发送信息给终端设备,当接入网设备接收到核心网设备发给终端设备的信息后,会向核心网设备发送失败消息或不向核心网设备发送任何回复。当接入网设备确定了终端设备进入上述第一省电模式后,并不会向核心网设备同步该终端设备的状态,则核心网设备还会发送信息给终端设备,当接入网设备接收到核心网设备发给终端设备的信息后,如果终端设备在监听寻呼信息的周期未到来时,会向核心网设备发送失败消息或不向核心网设备发送任何回复,如果该周期到来,则会将寻呼信息发送给终端设备。
可见,本实施例的方法中,终端设备可以在连接态与本实施例中所述的省电模式之间直接转换,在这个过程中,本实施例的接入网设备需要根据确定的第一时间信息和第二时间信息,同步地确定终端设备的状态,且对接入层的配置进行保留和恢复,而接入网设备的其它执行流程可以按照现有流程进行处理,在此不进行赘述,使得可以通过对现有的系统进行较小的改变,即可实现连接态与本实施例中所述的省电模式之间直接转换。
本发明方法实施例三和四
提供分别一种终端设备的状态处理方法,主要是应用于终端设备所处的移动网络系统中,由终端设备所在网络的接入网设备所执行的方法,其中接入网设备是终端设备所在接入网中部署的设备,比如RNC等,则终端设备的状态处理方法包括:
A1:确定终端设备的状态,主要是当终端设备在连接态与省电模式之间 直接转换时,接入网设备也会同步地确定终端设备的状态。
A2:根据上述步骤A1确定的终端设备的状态,与核心网设备之间进行终端设备的状态同步,即接入网设备会同步地将终端设备的状态通知给核心网设备。
A3:根据上述步骤A1确定的终端设备的状态,当终端设备从连接态进入省电模式时,保留终端设备在连接态时接入层的配置;当终端设备从省电模式返回连接态时,恢复接入层的配置的使用。其中,接入网设备保留的终端设备在连接态时接入层的配置,具体可以包括:无线资源控制连接等连接的信息,进一步地,该接入层的配置还可以包括:分组数据协议激活信息,鉴权信息,安全认证信息,及终端设备所在网络的接入网设备与核心网设备之间的接口信息等。且接入层的配置还可以包括:终端设备在连接态时启动的任何一个定时器的信息等。
需要说明的是,上述终端设备所处的省电模式可以包括第一省电模式或第二省电模式,则当终端设备处于第一省电模式时,接入网设备不仅需要保留接入层的配置,且需要周期性地发送寻呼信息给所述终端设备;当终端设备处于第二省电模式时,接入网设备不发送信息给所述终端设备,但需要保留接入层的配置,即在第二省电模式下,终端设备对于网络是不可达的。
在具体实现的过程中,接入网设备可以分别通过如下方法实施例三和四,与核心网设备之间进行终端设备的状态同步,具体地:
本发明方法实施例三,方法流程图如图9所示,包括:
步骤301,接入网设备确定终端设备从连接态进入省电模式的第一时间信息,及终端设备从省电模式返回的连接态第二时间信息。
上述第一时间信息和第二时间信息可以是终端设备与核心网设备之间进行协商,或终端设备与核心网设备协商好后,由终端设备或核心网设备告知接入网设备的,具体地:在一种情况下,接入网设备接收终端设备发送的第一请求消息,该第一请求消息用于请求接入网设备配置第一时间信息和/或第二时间信息;接入网设备向终端设备返回的第一响应消息,第一响应消息中包括第一时间信息和/或第二时间信息。在另一种情况下,接入网设备直接接收终端设备或核心网设备发送的第一时间信息和/或第二时间信息,第一时间信息和/ 或第二时间信息是由核心网设备与终端设备协商好后发送给接入网设备的。
步骤302,接入网设备根据上述步骤301确定的第一时间信息,当确定终端设备从连接态进入省电模式时,执行步骤303;如果根据上述步骤301确定的第二时间信息,当确定终端设备从省电模式返回连接态时,执行步骤304。
具体地,如果上述第一时间信息和第二时间信息分别为第一预置时间和第二预置时间,则当所述终端设备进入连接态的时间超过所述第一预置时间,且没有上下行数据时,确定所述终端设备进入省电模式;当所述终端设备进入所述省电模式的时间或所述终端设备进入所述连接态的时间点到当前时刻的时间超过第二预置时间时,确定所述终端设备从所述省电模式返回所述连接态。
步骤303,接入网设备与核心网设备之间进行终端设备的状态同步,具体地,接入网设备将第一状态信息发送给核心网设备,在第一状态信息中包括终端设备进入省电模式的信息。且接入网设备会保留终端设备在连接态时接入层的配置。
进一步地,如果接入网设备确定终端设备是进入上述第一省电模式,则可以在上述第一状态信息中还包括终端设备监听寻呼信息的周期信息,使得核心网设备可以根据该周期信息,在终端设备处于第一省电模式时,可以周期性地发送寻呼信息给终端设备;或者接入网设备只是在第一状态信息中包括终端设备进入第一省电模式的信息,而在核心网设备中已经预置了该周期信息,则核心网设备也可以在终端设备处于第一省电模式时,周期性地发送寻呼信息给终端设备。
步骤304,恢复所述接入层的配置的使用。
可见,在本实施例中,终端设备可以在省电模式与连接态之间直接转换,且当从连接态进入到省电模式时,终端设备会保留在连接态时接入层的配置,而在这个过程中,接入网设备需要将上述第一状态信息发送给核心网设备,使得核心网设备得知在什么时候不要寻呼或发送数据给该终端设备,在什么时候只是周期性地寻呼该终端设备,这样能节省了核心网设备的信令流程。
需要说明的是,接入网设备还可以通过如下几种方式,与核心网设备之间同步终端设备的状态:
(1)当接入网设备确定终端设备从连接态进入省电模式后,接入网设备 还可以发送第二状态信息给核心网设备,第二状态信息中包括:终端设备离开所述省电模式的信息。这样在终端设备离开省电模式后,核心网设备就可以正常寻呼或发送数据给该终端设备了。
具体地,在其中一种情况下,当终端设备从连接态进入省电模式时,接入网设备可以先不发送该终端设备进入省电模式的信息给核心网设备,这样核心网设备会继续寻呼或发送数据给终端设备,而核心网设备发送给终端设备的信息(包括寻呼消息或数据包等)会先经过接入网设备;当接入网设备接收到这些信息时,则会发送上述第二状态信息给核心网设备,而在第二状态信息中包括的信息指示终端设备离开省电模式的时间信息。在另一种情况下,当接入网设备确定终端设备从连接态进入省电模式后,又从省电模式再返回到连接态时,发送第二状态信息,该第二状态信息中包括的信息是指终端设备已经离开省电模式的信息。
(2)当接入网设备确定终端设备离开连接态时,还可以将第四状态信息发送给核心网设备,该第四状态信息中包括:终端设备离开连接态的信息。这里终端设备离开连接态可以是指终端设备从连接态进入省电模式,或从连接态进入到其它状态,则核心网设备会根据该第四状态信息,确定终端设备从连接态进入省电模式或其它状态,具体地,当终端设备进入省电模式的时间或终端设备进入连接态的时间点到当前时刻的时间超过第二预置时间时,确定终端设备时进入了省电模式。
本发明方法实施例四,方法流程图如图10所示,包括:
步骤401,接入网设备在确定终端设备的状态时,当确定终端设备进入连接态,执行步骤402。
步骤402,接入网设备将第三状态信息发送给核心网设备,在第三状态信息中包括终端设备进入连接态的信息,该第三状态信息,主要用于核心网设备在接收到该第三状态信息后,根据该第三状态信息,及终端设备从连接态进入省电模式的第一时间信息,确定该终端设备进入省电模式,具体地,当所述终端设备进入所述连接态的时间超过第一预置时间,且没有上下行数据时,则确定所述终端设备进入省电模式。
步骤403,接入网设备根据与终端设备之间同步的终端设备的状态,如果 确定终端设备从连接态进入省电模式时,保留终端设备在连接态时接入层的配置;当终端设备从省电模式返回连接态时,恢复接入层的配置的使用。
其中,接入网设备确定终端设备从连接态进入省电模式的第一时间信息,及终端设备从省电模式返回的连接态第二时间信息。这样接入网设备就可以根据该第一时间信息确定当终端设备进入连接态后的什么时间进入省电模式,根据该第二时间信息确定终端设备什么时候离开省电模式,然后接入网设备就可以执行该步骤403了。上述第一时间信息和第二时间信息可以是终端设备与核心网设备之间进行协商,或终端设备与核心网设备协商好后,由终端设备告知接入网设备的。
具体地,如果上述第一时间信息和第二时间信息分别为第一预置时间和第二预置时间,则当终端设备进入连接态的时间超过第一预置时间,且没有上下行数据时,确定终端设备进入省电模式;当终端设备进入省电模式的时间或终端设备进入连接态的时间点到当前时刻的时间超过第二预置时间时,确定终端设备从省电模式返回连接态。
可见,在本实施例中,终端设备可以在省电模式与连接态之间直接转换,且当进入连接态进入到省电模式时,终端设备会保留在连接态时接入层的配置,而在这个过程中,接入网设备需要将上述第三状态信息发送给核心网设备,核心网设备在确定终端设备进入到省电模式时,不会寻呼或发送数据给该终端设备或周期性地寻呼该终端设备,这样能节省了核心网设备的信令流程。
需要说明的是,接入网设备还可以通过如下几种方式,与核心网设备之间同步终端设备的状态:
(1)当接入网设备确定终端设备从连接态进入省电模式后,可以发送第二状态信息给核心网设备,第二状态信息中包括终端设备离开省电模式的信息。
在一种情况下,当所述终端设备从连接态进入省电模式后,接入网设备可以先不发送该终端设备已经进入省电模式的信息给核心网设备,这样核心网设备会继续寻呼或发送数据给终端设备,而核心网设备发送给终端设备的信息(包括寻呼消息或数据包等)会先经过接入网设备;当接入网设备接收到这些信息时,可以发送第二状态信息给核心网设备,而在第二状态信息中的信息指 示终端设备离开省电模式的时间信息。
在另一种情况下,当接入网设备确定终端设备从连接态进入省电模式后,又从省电模式再返回到连接态时,会发送第二状态信息,该第二状态信息中包括的信息是指终端设备已经离开省电模式的信息。
(2)当接入网设备确定终端设备离开连接态时,接入网设备还可以将第四状态信息发送给核心网设备,该第四状态信息中包括:终端设备离开连接态的信息,该第四状态信息,用于核心网设备根据第四状态信息,确定终端设备从连接态进入省电模式或进入其它状态。这里终端设备离开连接态可以是指终端设备从连接态进入省电模式,或从连接态进入到其它状态,则核心网设备会根据该第四状态信息,就能确定终端设备从连接态进入到省电模式还是进入到其它状态。
本发明方法实施例五和六
提供分别一种终端设备的状态处理方法,主要是应用于终端设备所处的移动网络系统中,由核心网设备所执行的方法,其中核心网设备是核心网中部署的设备,比如SGSN等,则终端设备的状态处理方法包括:
B1:与终端设备所在网络的接入网设备之间进行终端设备的状态同步,主要是当终端设备在连接态与省电模式之间直接转换时,接入网设备会将终端设备的状态同步给核心网设备。
B2:根据上述步骤B1同步的终端设备的状态,当终端设备从连接态进入省电模式时,保留终端设备在连接态时连接的配置;当终端设备从省电模式返回连接态时,恢复连接的配置的使用。其中,核心网设备保留的终端设备在连接态时连接的配置,具体可以包括:分组数据协议激活信息,鉴权信息,安全认证信息,或终端设备所在网络的接入网设备与核心网设备之间的接口信息等。且接入层的配置还可以包括:终端设备在连接态时启动的任何一个定时器的信息等。
需要说明的是,上述终端设备所处的省电模式可以包括第一省电模式或第二省电模式,则当终端设备处于第一省电模式时,核心网设备不仅需要保留连接的配置,且还可以周期性地发送寻呼信息给所述终端设备;当终端设备处于 第二省电模式时,核心网设备不发送信息给所述终端设备,但需要保留连接的配置,即在第二省电模式下,终端设备对于网络是不可达的。
在具体实现的过程中,核心网设备可以分别通过如下方法实施例五和六,与接入网设备之间进行终端设备的状态同步,具体地:
本发明方法实施例五,方法流程图如图11所示,包括:
步骤501,核心网设备在与接入网设备之间进行终端设备的状态同步时,核心网设备接收终端设备所在网络的接入网设备发送的第一状态信息,第一状态信息中包括终端设备进入省电模式的信息。
步骤502,核心网设备根据该第一状态信息,确定终端设备进入省电模式,且保留终端设备在连接态时连接的配置。
在本实施例中,如果核心网设备接收的第一状态信息是指终端设备已经进入上述第二省电模式的信息,则说明终端设备是不可达的,核心网设备还可以根据所述第一状态信息,停止寻呼或停止发送数据给所述终端设备;如果核心网设备接收的第一状态信息中除了包括终端设备进入省电模式的信息,还包括终端设备监听寻呼信息的周期信息,则说明终端设备进入了上述第一省电模式,则核心网设备还可以根据所述第一状态信息,周期性地寻呼该终端设备;如果核心网设备接收的第一状态信息中的信息指示终端设备进入上述第一省电模式,则核心网设备根据所述第一状态信息及预置的周期信息,周期性地寻呼该终端设备。
可见,在本实施例中,终端设备可以在省电模式与连接态之间直接转换,且当从连接态进入到省电模式时,终端设备会保留在连接态时接入层的配置,而在这个过程中,接入网设备需要将上述第一状态信息发送给核心网设备,使得核心网设备根据该第一状态信息,不寻呼或不发送数据给该终端设备,或只是周期性地寻呼该终端设备,这样能节省了核心网设备的信令流程。
需要说明的是,核心网设备还可以通过如下几种方式,与接入网设备之间同步终端设备的状态:
(1)核心网设备接收到接入网设备发送的第二状态信息,第二状态信息中包括:终端设备离开所述省电模式的信息,其中,第二状态信息是所述终端设备从所述连接态进入省电模式后,所述接入网设备发送的;则核心网设备根 据第二状态信息,确定终端设备返回寻呼进到状态,则开始寻呼或开始发送数据给终端设备,确定在什么时候离开省电模式。
在其中一种情况下,如果终端设备从连接态进入省电模式后,核心网设备通过所述接入网设备向所述终端设备发送信息时,才接收到所述接入网设备发送的所述第二状态信息,所述第二状态信息中包括的信息指示所述终端设备离开所述省电模式的时间信息,则核心网设备可以根据该第二状态信息,在确定终端设备离开所述省电模式时,开始正常寻呼或开始发送数据给所述终端设备。在另一种情况下,如果终端设备从连接态进入省电模式后,又从省电模式返回所述连接态时,核心网设备会接收到所述接入网设备发送的所述第二状态信息,则第二状态信息中包括的信息指示所述终端设备已经离开所述省电模式。
(2)当终端设备离开连接态时,接入网设备会向核心网设备发送第四状态信息,当核心网设备接收接入网设备发送的第四状态信息,该第四状态信息中包括:终端设备离开连接态的信息,这里终端设备离开连接态具体可以是指终端设备从连接态进入省电模式,或终端设备从连接态进入到其它状态。则核心网设备会根据该第四状态信息,就能确定终端设备从连接态进入省电模式还是进入其它状态,具体地,如果终端设备进入连接态的时间超过第一预置时间且没有上下行数据时,则确定终端设备是从连接态进入了省电模式;如果终端设备进入连接态的时间未超过第一预置时间,或超过第一预置时间且有上下行数据时,则确定终端设备是从连接态进入了其它状态,则停止对终端终端设备进入省电模式的时间进行计时,或停止对终端设备进入连接态的时间点到当前时刻的时间进行计时,可以根据该第四状态信息执行其它状态的操作,比如开始正常寻呼或开始发送数据给终端设备。
本发明方法实施例六,方法流程图如图12所示,包括:
步骤601,核心网设备确定终端设备从连接态进入省电模式的第一时间信息,及终端设备从省电模式返回的连接态第二时间信息。
步骤602,在核心网设备与接入网设备之间进行终端设备的状态同步时,如果终端设备进入连接态时,核心网设备接收终端设备所在网络的接入网设备发送的第三状态信息,第三状态信息中包括终端设备进入连接态的信息。
步骤603,核心网设备根据该第三状态信息,及终端设备从连接态进入省电模式的第一时间信息,确定该终端设备进入省电模式,并保留终端设备在连接态时连接的配置。
步骤604,核心网设备根据终端设备从省电模式返回的连接态第二时间信息,确定终端设备返回寻信道状态时,恢复上述连接的配置的使用。
在具体实现过程中,该第一时间信息和第二时间可以分别是第一预置时间和第二预置时间,则当终端设备进入连接态的时间超过第一预置时间,且没有上下行数据时,核心网设备确定终端设备进入省电模式;当终端设备进入省电模式的时间或所述终端设备进入连接态的时间点到当前时刻的时间超过第二预置时间时,核心网设备确定终端设备从省电模式返回连接态。
可见,在本实施例中,终端设备可以在省电模式与连接态之间直接转换,且当从连接态进入到省电模式时,终端设备会保留在连接态时接入层的配置,而在这个过程中,接入网设备需要将上述第三状态信息发送给核心网设备,使得核心网设备对终端设备进入连接态的时间进行计时,当根据该计时时间,确定终端设备进入省电模式时,不寻呼或不发送数据给该终端设备,或者只是周期性地寻呼终端设备,这样能节省了核心网设备的信令流程。
需要说明的是,核心网设备还可以通过如下几种方式,与接入网设备之间同步终端设备的状态:
(1)核心网设备接收到接入网设备发送的第二状态信息,第二状态信息中包括:终端设备离开所述省电模式的信息,其中,第二状态信息是所述终端设备从所述连接态进入省电模式后,所述接入网设备发送的;则核心网设备根据第二状态信息,确定终端设备返回寻呼进到状态,则开始寻呼或开始发送数据给终端设备,确定在什么时候离开省电模式。
在其中一种情况下,如果终端设备从连接态进入省电模式后,核心网设备通过所述接入网设备向所述终端设备发送信息时,才接收到所述接入网设备发送的所述第二状态信息,所述第二状态信息中包括的信息指示所述终端设备离开所述省电模式的时间信息,则核心网设备可以根据该第二状态信息,在确定终端设备离开所述省电模式时,开始正常寻呼或开始发送数据给所述终端设备。在另一种情况下,如果终端设备从连接态进入省电模式后,又从省电模式 返回所述连接态时,核心网设备会接收到所述接入网设备发送的所述第二状态信息,则第二状态信息中包括的信息指示所述终端设备已经离开所述省电模式。
(2)当终端设备离开连接态时,接入网设备会向核心网设备发送第四状态信息,当核心网设备接收接入网设备发送的第四状态信息,该第四状态信息中包括:终端设备离开连接态的信息,这里终端设备离开连接态具体可以是指终端设备从连接态进入省电模式,或终端设备从连接态进入到其它状态。则核心网设备会根据该第四状态信息,就能确定终端设备从连接态进入省电模式还是进入其它状态,具体地,如果终端设备进入连接态的时间超过第一预置时间且没有上下行数据时,则确定终端设备是从连接态进入了省电模式;如果终端设备进入连接态的时间未超过第一预置时间,或超过第一预置时间且有上下行数据时,则确定终端设备是从连接态进入了其它状态,则停止对终端终端设备进入省电模式的时间进行计时,或停止对终端设备进入连接态的时间点到当前时刻的时间进行计时,可以根据该第四状态信息执行其它状态的操作,比如开始正常寻呼或开始发送数据给终端设备。
以下以几个具体的应用实施例来说明本发明实施例中提供的方法,在这些实施例中接入网设备为RNC,核心网设备为SGSN,其中终端设备所处的省电模式为上述第二省电模式。
本发明方法实施例七,方法流程图如图13所示,包括:
步骤701,终端设备向SGSN发送NAS消息比如附着请求消息,或发送TAU/RAU请求消息(Request Message)时,在这些消息中携带该终端设备推荐使用的第一预置时间和第二预置时间,用来请求SGSN配置这两个时间。
步骤702,SGSN会在附着接受消息,或TAU/RAU接受(Accept)消息中携带SGSN最终确定的第一预置时间和/或第二预置时间。
可以理解,终端设备、RNC和SGSN,在终端设备与SGSN协商完上述第一预置时间和第二预置时间后,终端设备可以通过小区更新(Cell Update)或无线信道配置(Radio Channel Reconfiguration)消息,将协商好的第一预置时间和第二预置时间发送给RNC;同时RNC也会应答终端设备,该RNC是 否支持连接态与省电模式直接转换的功能,只有终端设备和RNC都支持才会进行后续的步骤。
或者,由SGSN将协商好的第一预置时间和第二预置时间通知给RNC。
或者,在其它情况下,RNC会在系统信息块(SIB)中携带该RNC是否支持连接态与省电模式直接转换的功能的信息,发送给终端设备,只有在支持的情况下,才会执行上述701和702的步骤。
步骤703,当终端设备进入连接态时,同时启动定时器T1和T2,其超时时间分别为第一预置时间及第二预置时间,如果定时器T1超时且没有上下行数据时,则终端设备会从连接态进入省电模式,此时,终端设备对核心网不可达,即核心网设备无法寻呼到或不能发送数据给该终端设备,且在AS的配置保持不变,所有已经开始运行的定时器继续运行,但终端设备不需要执行任何连接态下的任务。如果定时器T2超即终端设备在上述进入连接态的时间点到当前时刻的时间超过第二预置时间时,则终端设备从省电模式返回连接态。
需要说明的是,一种情况下,当终端设备处于省电模式的过程,如果有数据传输或信令传输,则终端设备可以结束省电模式而进入连接态,并从连接态发起传输业务。在另一种情况下,当终端设备处于省电模式的过程中,如果有信令传输时,则终端设备会等待定时器T2超时时,才进行信令传输。以下以连接操作为终端设备进入连接态时的小区更新操作为例说明。
当终端设备进入连接态后,会启动定时器T305,用于此状态下的周期性的小区更新。具体地:
A、如果定时器T305的时间小于定时器T1的时间,则在终端设备未进入省电模式时,终端设备就会执行小区更新操作,使得终端设备离开连接态而进入其它状态,则使得定时器T1终止,而终端设备始终不会进入省电模式。
B、如果定时器T305的时间等于定时器T1的时间,则T305和T1会同时超时,终端设备只能满足一个定时器的动作要求,为保证终端设备能进入省电模式,不作定时器T305超时对应的小区更新行为。
C、如果定时器T305的时间大于定时器T1的时间,且小于定时器T2的时间,则说明当终端设备进入省电模式后,定时器T305才超时,需要进行小区更新操作,此时,终端设备可以立即结束省电模式来执行该小区更新操作, 或者等待定时器T2超时时,才执行该小区更新操作。
D、如果定时器T305的时间等定时器T2的时间,则终端设备每次从省电模式返回到连接态时,都需要进行小区更新操作。
步骤704,在执行上述步骤703的同时,RNC将终端设备进入连接态的信息通知给SGSN,则SGSN根据上述步骤701与702中协商的第一预置时间和第二预置时间,同时启动定时器T1和T2,在定时器T1超时后如果终端设备没有上下行数据,则SGSN就停止寻呼或停止发送数据给终端设备,并在定时器T2超时时,开始寻呼或开始发送数据给终端设备。具体地,RNC可以通过直接信息传输(DIRECT INFORMATION TRANSFER)消息通知SGSN,也可以通过其它消息比如位置上报(Location Report)等消息通知SGSN。
如果在定时器T1超时前,终端设备离开连接态,则RNC将终端设备离开连接态的信息发送给SGSN,这样SGSN会停止定时T1和T2的运行。如果在定时器T1超时后,且定时器T2未超时时,终端设备自行决定结束省电模式,则RNC将终端设备离开省电模式的信息发送给SGSN,这样SGSN会开始寻呼或开始发送数据给终端设备。
以“直接信息传输”消息为例,说明RNC如何携带这些状态信息,如表1所示:
表1
Figure PCTCN2015079202-appb-000001
Figure PCTCN2015079202-appb-000002
可见,在直接信息传输消息中可以包括信元(Information Element,IE)/组名称(Group Name),是否存在(Presence),信元类型和参考(IE type and reference),语义描述(Semantics description),是否临界(Criticality)及指定临界(Assigned Criticality)等字段。其中,在直接信息传输消息中可以包括如下信元:消息类型(Message Type),内系统信息传输类型(Inter-system Information Transfer Type),核心网域指示(CN Domain Indicator),全球RNC标识(Global RNC-ID),全球核心网标识(Global CN-ID),扩展的RNC标识(Extended RNC-ID)及终端设备进入或离开PCH状态(Enter/Leave PCH state)等信元。
而通过“进入或离开状态”信元的“O”值表示终端设备进入PCH状态,在其它情况下,可以用值“1”表示终端设备进入PCH状态,用值“0”表示终端设备离开PCH状态。
本发明方法实施例八,方法流程图如图14所示,包括:
步骤801,终端设备向SGSN发送附着请求或TAU/RAU请求消息,其中携带第二预置时间。
步骤802,SGSN向终端设备返回附着接受,或TAU/RAU接受消息,其 中携带最终确定的第二预置时间。与上述实施例七类似,终端设备也可以将该第二预置时间发送给RNC,以确定RNC也支持连接态与省电模式之间的之间转换的功能,才执行后续的步骤。或者,由SGSN将协商好的第二预置时间通知给RNC。
步骤803,当终端设备进入连接态时,启动定时器T1,当定时器T1超时且没有上下行数据时,终端设备进入省电模式,同时启动定时器T2,如果定时器T2超(即终端设备进入省电模式的时间超过第二预置时间)时,则终端设备从省电模式返回连接态。其中定时器T2的超时时间为上述步骤801和802中协商的第二预置时间,定时器T1可以用上述的定时器T305来代替,即当终端设备进入连接态时,再启动一个定时器T305,该定时器T1的时间也可以按照上述步骤801和802的方法进行协商得到第一预置时间。
在本实施例中,终端设备根据定时器T1、T2和T305的时间之间关系进行的操作与上述实施例七类似,不同的是在上述的C情况下,是当定时器T305的时间大于定时器T1的时间,且小于定时器T1和T2的时间之和时,执行上述相应的操作;而在上述的D情况下,是当定时器T305的时间等于定时器T1和T2的时间之和时,执行上述相应的操作。
步骤804,在执行上述步骤803的同时,如果终端设备从连接态进入省电模式,则RNC将终端设备进入省电模式的信息通知给SGSN,这样SGSN会停止寻呼或停止发送数据给该终端设备,且SGSN可以按照上述协商好的第二预置时间,启动定时器T2,如果定时器T2超时时,则SGSN开始寻呼或开始发送数据给终端设备。
如果在定时器T2未超时时,终端设备临时决定从省电模式返回连接态,则RNC将终端设备离开省电模式的信息通知给SGSN,这样SGSN会开始寻呼或开始发送数据给该终端设备。
具体地,RNC可以通过直接信息传输消息或其它消息将这些状态信息发送给SGSN,其中直接信息传输消息的结构与上述表1中类似,不同的是,本实施例中,在直接信息传输消息中没有“进入或离开状态”的信元,而是包括“进入省电模式的标识”信元,用于指示终端设备是否进入省电模式。
本发明方法实施例九,方法流程图如图15所示,包括:
步骤901,终端设备向RNC发送RRC消息,其中携带第一预置时间和第二预置时间,RRC消息可以是服务请求(Service Request)或小区更新(Cell Update)消息。
步骤902,RNC向终端设备返回最终确定的第一预置时间和第二预置时间,具体可以携带在小区更新确认(Cell update Confirm)消息中发送给终端设备。由终端设备或RNC将最终确定的第一预置时间和第二预置时间发送给SGSN,完成三方协商。
步骤903,当终端设备进入连接态时,启动定时器T1,当定时器T1超时且没有上下行数据时,终端设备进入省电模式,同时启动定时器T2,如果定时器T2超时,则终端设备从省电模式返回连接态。其中定时器T1和T2的超时时间分别为第一预置时间和第二预置时间。
步骤904,在执行上述步骤903的同时,当终端设备的状态发生改变时,RNC通知给SGSN的信息与上述步骤604类似,在此不进行赘述。
而在另一种情况下,当SGSN接收到RNC发送的终端设备进入省电模式的信息时,也可以不用启动定时器T2,则RNC必须将终端设备离开省电模式的信息也通知给SGSN,这样SGSN可以知道从什么时候开始寻呼或开始发送数据给终端设备。
本发明方法实施例十,方法流程图如图16所示,包括:
步骤1001,终端设备向RNC发送RRC消息,其中携带第一预置时间和第二预置时间,RRC消息可以是服务请求或小区更新消息。
步骤1002,RNC向终端设备返回最终确定的第一预置时间和第二预置时间,具体可以携带在小区更新确认消息中发送给终端设备。由终端设备会RNC将最终确定的第一预置时间和第二预置时间发送给SGSN,完成三方协商。
步骤1003,当终端设备进入连接态时,启动定时器T1,当定时器T1超时且没有上下行数据时,终端设备进入省电模式,同时启动定时器T2,如果定时器T2超时,则终端设备从省电模式返回连接态。其中定时器T1和T2的超时时间分别为第一预置时间和第二预置时间。
步骤1004,在执行上述步骤1003的同时,当终端设备进入省电模式时,RNC不会将终端设备进入省电模式的信息发送给SGSN,这样SGSN还是会 寻呼或发送数据给该终端设备;当SGSN发送给终端设备的信息达到RNC时,此时RNC会将终端设备离开省电模式的时间信息通知给SGSN,这样SGSN就知道什么时候开始寻呼或开始发送数据给终端设备,或者RNC不会将终端设备离开省电模式的时间信息通知给SGSN,而是向SGSN发送失败消息或不向SGSN发送任何回复。
如果在定时器T2未超时时,终端设备临时决定从省电模式返回连接态,则RNC将终端设备离开省电模式的信息通知给SGSN,这样SGSN会开始寻呼或开始发送数据给该终端设备。
下面对本发明实施例中的寻呼方法进行描述:
需要说明的是,本发明实施例中,第一非连续接收技术中非连续接收周期的长度大于第二非连续接收技术中非连续接收周期的长度,该第二非连续接收技术中非连续接收周期的长度的最大取值为5.12秒,该第二非连续接收技术可以为普通的非连续接收技术DRX,其非连续接收周期的长度的最大取值可以为5.12秒,该第一非连续接收技术可以为增强的非连续技术eDRX,该第一非连续接收技术中非连续接收周期的长度大于该第二非连续接收技术中非连续接收周期的长度,例如可以为40.96秒。其中,第一非连续接收技术相对于第二非连续接收技术,在UE计算寻呼时机的机制上不变,仅拉长了非连续接收的周期。
需要说明的是,在确定了非连续接收周期的长度后,可以计算被寻呼的用户设备(假设为上述UE)的寻呼时机:
具体的,根据被寻呼的用户设备的国际移动用户识别码(International Mobile Subscriber Identification Number,IMSI)和被寻呼的用户设备的非连续接收周期长度,可以按照如下公式(1)计算被寻呼的用户设备的寻呼时机;
PO={(IMSI/K)%(DRXcycle/PBP)}*PBP+n*DRXcycle+FO;n=0,1,2…m,当n≦m时,PO≦4095;   公式(1)
其中,m为n的最大值,当n>m时,PO>4095。
其中,在上述公式(1)中,PO为被寻呼的用户设备的寻呼时机,DRXcycle为被寻呼的用户设备的非连续接收周期长度,K为该小区中承载寻呼消息的信道的个数,%为取模运算,针对于频分复用系统,PBP为1,FO为0。

可以理解的是,本步骤中,SGSN通过Iub接口将该第一参数发送给RAN,在实际应用中,可选的,若SGSN确定RAN不支持该第一非连续接收技术,该SGSN还可以通过Iub接口将用于确定第二非连续接收技术中非连续接收周期长度的第二参数发送给RAN。
1703、RAN按照接收到的该第一参数,采用该第一非连续接收技术计算第三寻呼时机;
本步骤中,RAN支持该第一非连续接收技术,RAN接收到SGSN发送的第一参数后,按照接收到的该第一参数,采用该第一非连续接收技术计算第三寻呼时机。
可选的,在实际应用中,若RAN不支持该第一非连续接收技术,则RAN会基于接收到SGSN发送的第二非连续接收技术的第二参数,采用第二非连续接收技术计算第四寻呼时机。
1704、RAN通过广播消息指示UE该RAN是否支持该第一非连续接收技术;
具体的,当RAN支持第一非连续接收技术时,该RAN可以在发送的广播消息中携带第一非连续接收技术标志;
可选的,该第一非连续接收技术标志可以为第一非连续接收技术指示,也可以为预置长度的非连续接收周期等,该预置长度大于该第二非连续接收技术DRX中非连续接收周期的长度的最大取值5.12秒,还可以采用其他的第一非连续接收技术标志,此处不作限定。

当确定不携带所述第一非连续接收技术标志时,该UE确定所述RAN不支持所述第一非连续接收技术。
本步骤中,当该UE根据该广播消息确定RAN支持第一非连续接收技术时,该UE按照所述第一参数,采用所述第一非连续接收技术计算第一寻呼时机。
在实际应用中,当该UE根据该广播消息确定RAN不支持第一非连续接 收技术时,该UE可以采用该第二非连续接收技术计算第二寻呼时机。
1706、UE和RAN按照计算出的寻呼时机完成寻呼。
本步骤中,RAN可以按照计算出的寻呼时机发送寻呼指示给UE,而UE可以按照计算出的寻呼时机侦听RAN发送的寻呼指示,按照计算出的寻呼时机完成寻呼。
具体的,网络侧计算被寻呼的用户设备的寻呼时机,在该寻呼时机向被寻呼的用户设备发送寻呼指示,该寻呼指示中携带被寻呼的用户设备的标识和寻呼数据。
当该用户设备的寻呼时机到达时,该用户设备监听PICH(Page Indication Channel,寻呼指示信道)并对该PICH信道的寻呼指示值进行解析,如果解析到该PICH信道中的寻呼指示值为1,则该用户设备接收该寻呼消息,判断自身的标识和该寻呼消息中携带的标识是否相同,如果相同,则保留该寻呼数据,如果不同,则丢弃该寻呼数据。
本发明实施例中,UE能根据RAN发送的广播消息中是否携带第一非连续接收技术标志来自动选择使用第一非连续接收技术计算寻呼时机,还是使用第二非连续接收技术计算寻呼时机,提升了UE在使用不同的非连续接收技术的网络系统中的适应性。
上面从各设备的信令交互的角度对本发明实施例中的寻呼方法进行了描述,下面分别从各个设备的角度,对本发明实施例中寻呼方法进行描述:
一、从UE的角度对本发明实施例中寻呼方法进行描述:
请参阅图18,本发明实施例中寻呼方法另一个实施例包括:
1801、UE与核心网设备协商第一参数,所述第一参数用于确定第一非连续接收技术中非连续接收周期的长度,所述第一非连续接收技术中非连续接收周期的长度大于第二非连续接收技术中非连续接收周期的长度,所述第二非连续接收技术中非连续接收周期的长度的最大取值为5.12秒;
与步骤1701类似,此处不作赘述。
1802、所述UE接收无线接入网RAN发出的广播消息;
UE可以接收RAN发送的广播消息,该广播消息用于指示该RAN是否支持第一非连续接收技术。
UE可以根据该广播消息确定RAN是否支持第一非连续接收技术;
若确定RAN支持第一非连续接收技术,则执行步骤1803;
若确定RAN不支持第一非连续接收技术,则执行步骤1804.
可选的,UE可以判断该广播消息中是否携带第一非连续接收技术标志;
当确定携带所述第一非连续接收技术标志时,所述UE确定所述RAN支持所述第一非连续接收技术;
当确定不携带所述第一非连续接收技术标志时,所述UE确定所述RAN不支持所述第一非连续接收技术。
1803、当所述UE根据所述广播消息确定所述RAN支持所述第一非连续接收技术时,所述UE按照所述第一参数,采用所述第一非连续接收技术计算第一寻呼时机;

1804、当所述UE根据所述广播消息确定所述RAN不支持所述第一非连续接收技术时,所述UE采用所述第二非连续接收技术计算第二寻呼时机;
在实际应用中,在确定的应用场景下,由于RAN仅能为支持第一非连续接收技术,或不支持第一非连续接收技术中的一种情况,因此,根据实际情况,步骤1803与1804中仅有一个步骤会执行。
1805、所述UE按照计算出的第一寻呼时机或第二寻呼时机侦听所述RAN发出的寻呼指示。
需要说明的是,由于第一非连续接收技术支持在多个寻呼指示信道上侦听寻呼指示,因此,可选的:

当所述UE根据所述广播消息确定所述RAN支持所述第一非连续接收技术时,所述UE在第二寻呼指示信道或所述第一寻呼指示信道上按照计算出的第一寻呼时机侦听所述RAN发出的寻呼指示,所述第二寻呼指示信道与所述 第一寻呼指示信道不同。
当然,在实际应用中,即使RAN支持第一非连续接收技术,UE也可以选择只在第一寻呼指示信道上按照计算出的第一寻呼时机侦听所述RAN发出的寻呼指示,此处不作限定。
本发明实施例中,UE能根据RAN发送的广播消息中是否携带第一非连续接收技术标志来自动选择使用第一非连续接收技术计算寻呼时机,还是使用第二非连续接收技术计算寻呼时机,提升了UE在使用不同的非连续接收技术的网络系统中的适应性。

2002、当所述核心网设备确定RAN支持所述第一非连续接收技术时,所述核心网设备通过Iub接口将所述第一参数发送给所述RAN。
