具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述。
图1为本发明实施例的一种应用场景的示意性架构图。如图1所示,网络100可以包括基站102、第一终端设备104、106以及第二终端设备108、110、112、114、116和118,其中,基站、第一终端设备、第二终端设备之间可以通过无线连接。
在基站102广播***信息时,处于基站102的覆盖范围内(In Coverage,IC)的第一终端设备104和106可以直接接收基站广播的***信息,处于基站102的覆盖范围内的第二终端设备112和114以及处于基站102的扩展覆盖范围内(Extended Coverage,EC)的第二终端设备110和116也均可以直接接收基站广播的***信息,或者可以接收第一终端设备104和106转发的***信息,处于基站102覆盖范围外(Out of Coverage,OOC)的第二终端设备108和118需要通过第一终端设备104和106接收基站广播的***信息。
基于图1的应用场景,本发明实施例提出一种传输***信息的方法,通过第一终端设备获取第二终端设备的第一指示信息,可以使第一终端设备能够知道第二终端设备需要的***信息类型,从而避免了第一终端设备向第二终端设备发送第二终端设备不需要的***信息,因此,能够减少第一终端设备与第二终端设备之间的信令交互,降低信令开销,避免资源浪费,下面结合图2对所述方法进行详细的描述。
图2是根据本发明实施例的传输***信息的方法200的示意性流程图,该方法200可以由第一终端设备执行,例如,可以由网络100中的第一终端设备104或第一终端设备106执行。如图2所示的方法200包括:
210,第一终端设备获取第一指示信息;
220,所述第一终端设备根据所述第一指示信息确定第二终端设备需要的***信息(System Information,SI),其中,所述第二终端设备通过所述第一终端设备与基站通信;
220,第一终端设备向第二终端设备发送包含目标SI的消息,目标SI为第二终端设备需要的SI中的至少部分SI。
在本发明实施例中,第一终端设备通过获取第二终端设备的第一指示信息,可以确定第二终端设备需要的***信息SI,使得第一终端设备向第二终 端设备转发第二终端设备需要的***信息,从而减少了第一终端设备与第二终端设备之间的信令交互,降低了信令开销,避免了资源浪费。
应理解,目标SI或第二终端设备需要的SI可以是***信息块(System Information Block,SIB)和/或SIB中的一部分参数,或者也可以是第二终端设备所有需要接收的参数的集合。
可选的,在一些实施例中,第一终端设备可以是中继终端设备,例如,可以是智能手机等设备,第二终端设备可以是可穿戴设备(Wearable Device,WD),例如,可以是智能手表,智能手环等终端设备,但发明实施例并不限定于此。
应理解,在本发明实施例中,第一终端设备与第二终端设备之间建立通信连接,该通信连接例如可以是基于蓝牙技术建立的配对关系,也可以是基于无线局域网(Wireless Local Area Networks,WLAN)技术建立的关联关系,或者也可以是基于长期演进技术(Long Term Evolution,LTE)中的设备到设备技术(Device to Device,D2D)建立的连接关系。
本发明实施例仅以配对关系、关联关系以及连接关系对第一终端设备与第二终端设备之间建立的通信连接进行说明,但本发明实施例不限定于此。
应理解,在第一终端设备与第二终端设备之间建立通信连接之后,第二终端设备为了节省电量,一般会选择将第一终端设备作为中继设备,与基站进行通信,即使该第二终端设备处于基站的覆盖范围内。例如,在可穿戴设备WD与中继终端设备之间建立D2D连接时,可穿戴设备大多数情况下会通过中继终端设备接收***信息。
可选的,在一些实施例中,第一指示信息可以是第二终端设备支持的能力。
例如,该第一指示信息可以是第二终端设备支持的扩展接入禁止(Extended Access Barring,EAB)的能力,也可以是第二终端设备支持的地震海啸预警***(Earthquake and Tsunami Warning System,ETWS)的能力,或者也可以是第二终端设备支持的商业移动预警服务(Commercial Mobile Alert Service,CMAS)的能力,或者第二终端设备支持的特定服务接入控制(Service Specific Access Control,SSAC)的能力,或者第二终端设备支持的数据通信特定应用拥塞控制(Application specific Congestion control for Data Communication,ACDC)的能力。
本发明实施例仅以上述五种第二终端设备支持的能力为例对第一指示信息进行说明,但本发明实施例并不限定于此。
可选的,在一些实施例中,第一指示信息也可以是第二终端设备需要的***信息类型。
可选的,在一些实施例中,第一终端设备获取第一指示信息可以为第一终端设接收第二终端设备发送的第一指示信息,即第二终端设备上报该第二终端设备支持的能力或该第二终端设备需要的***信息类型给第一终端设备。
可选的,在一些实施例中,第一终端设备获取第一指示信息还可以是第一终端设备接收基站或移动管理实体(Mobile Management Entity,MME)发送的第一指示信息。由于第二终端设备在第一次接入网络的时候,可能会向该第二终端设备所在小区的基站或MME注册该第二终端设备支持的能力或该第二终端设备需要的***信息类型,即第一指示信息,在第一终端设备需要获取第二终端设备的第一指示信息时,基站或MME可以将第二终端设备预先存储在基站的第一指示信息发送给第一终端设备。
在本发明实施例中,第一终端设备通过接收基站或MME发送的第一指示信息,可以避免第二终端设备向第一终端设备发送第一指示信息,从而减少第一终端设备与第二终端设备之间的信令交互,降低了信令开销,有利于第二终端设备节省电量。
图3所示为根据本发明实施例的传输***信息的方法300的示意性流程图。
在310中,第一终端设备与第二终端设备建立通信连接。

可选的,在一些实施例中,第一指示信息也可以是第二终端设备需要的***信息类型。
可选的,在一些实施例中,第一终端设备获取第一指示信息可以为第一终端设接收第二终端设备发送的第一指示信息。
可选的,在一些实施例中,第一终端设备获取第一指示信息还可以是第一终端设备接收基站发送的第一指示信息。
在330中,第一终端设备获取基站广播的***信息。
基站在广播***信息时,基站会将主信息块(Master Information Block,MIB)和SIB中的SIB1分别通过一条单独的无线资源控制(Radio Resource Control,RRC)消息进行广播,除MIB和SIB1之外的其他SIB可以通过多条RRC消息进行广播,即多个SIB可以放在一条RRC消息中由基站进行广播。
在340中,第一终端设备向第二终端设备发送包含目标SI的消息。
可选的,在一些实施例中,该目标SI为第二终端设备需要的SI中的至少部分SI。
可选的,在一些实施例中,第一终端设备向第二终端设备发送包含目标SI的消息可以为:在第一终端设备接收到指示***信息SI改变的寻呼消息的情况下,该第一终端设备接收小区广播的更新之后的***信息之后,该第一终端设备向第二终端设备发送第二终端设备需要的SI中的除MIB、SIB1、SIB10、SIB11、SIB12、SIB14之外的其他更新后的***信息,即第一终端设备向第二终端设备发送目标SI,该目标SI为第二终端设备需要的SI中的部分SI。
应理解,基站可以通过寻呼消息来指示***消息中除MIB、SIB1、SIB10、SIB11、SIB12、SIB14之外的其他***信息发生了改变。
基站还可以通过修改SIB1中的SystemInfoValueTag的数值来表明***消息中除MIB、SIB1、SIB10、SIB11、SIB12、SIB14之外的其他***信息发生了改变,其中,SystemInfoValueTag的数值用于指示***信息是否发生了改变,该SystemInfoValueTag的取值范围为0~31,当***信息发生改变时,该SystemInfoValueTag的数值加1,从而通过SystemInfoValueTag的数值是 否发生变化可以确定***信息是否发生了变化。
可选的,在一些实施例中,在第二终端设备为支持EAB能力的终端设备时,第一终端设备向第二终端设备发送的目标SI为SIB14。
即第一终端设备向第二终端设备发送包含目标SI的消息可以为:在第一终端设备接收到指示EAB参数改变的寻呼消息的情况下,第一终端设备向第二终端设备发送更新后的SIB14。
应理解,在第一终端设备收到指示EAB参数改变的寻呼消息时,该第一终端设备首先需要接收基站广播的SIB1,检查SIB1中的调度信息列表字段(Scheduling InfoList),确定该调度信息列表字段是否有SIB14,在该调度信息列表字段有SIB14时,该第一终端设备根据调度信息,接收该SIB14,并将该更新之后的SIB14发送给第二终端设备。

同样的,在第一终端设备接收到指示有ETWS辅通知(Secondary Notification)的寻呼消息时,第一终端设备首先接收SIB1,并检测SIB1中的调度信息列表字段,确定该调度信息列表字段中是否指示存在SIB11,若该调度信息列表字段指示存在SIB11,则第一终端设备根据调度信息接收SIB11,并将该SIB11发送给第二终端设备。
可选的,在一些实施例中,在第二终端设备为支持CMAS能力的终端设备时,第一终端设备向第二终端设备发送的目标SI为SIB12。
即第一终端设备向第二终端设备发送包含目标SI的消息可以为:第一 终端设备接收到指示有CMAS通知的寻呼消息的情况下,第一终端设备向第二终端设备发送SIB12。
应理解,在第一终端设备接收到指示有CMAS通知的寻呼消息时,第一终端设备首先接收SIB1,并检测SIB1中的调度信息列表字段,确定该调度信息列表字段中是否指示存在SIB12,若该调度信息列表字段中指示存在SIB12,则第一终端设备根据调度信息接收SIB12,并将该SIB12发送给第二终端设备。

在420中,第一终端设备获取第一指示信息。
可选的,在一些实施例中,第一指示信息可以是第二终端设备支持的能力。
例如,该第一指示信息可以是第二终端设备支持的EAB能力,也可以是第二终端设备支持的ETWS能力,或者也可以是第二终端设备支持的CMAS能力,或者是第二终端设备支持的SSAC能力,或者是第二终端设备支持的ACDC能力。

可选的,在一些实施例中,第一终端设备向目标终端设备组发送组播消息还可以为:在第一终端设备进行或完成小区重选、同频切换、异频切换、异***切换的情况下,第一终端设备以组播的形式向目标终端设备组中的所有终端设备发送目标SI,该目标终端设备组包含第二终端设备。

可选的,在一些实施例中,该第一终端设备向第二终端设备发送的广播消息可以为公共的***信息SI或公共的***信息SI中的部分参数,该公共的SI或公共的SI中的部分参数是所有的终端设备都必须接收的***信息或***信息中的参数。

由于SIB1或SIB1中的部分参数为公共的SI,所以在第一终端设备检测到SIB1发生变化的情况下,第一终端设备可以通过广播形式向所有的第二 终端设备发送更新之后的SIB1或SIB1中的部分参数。
可选的,在一些实施例中,第一终端设备向第二终端设备发送的广播消息还可以为搜索信息或Master Information Block-SL message,该搜索信息或Master Information Block-SL message携带目标SI,此时的目标SI为第二终端设备需要的SI或第二终端设备需要的SI中的至少部分SI。
由于该搜索信息或Master Information Block-SL message为第一终端设备周期性广播的信息,所以第一终端设备向第二终端设备发送目标SI时,可以将该目标SI携带在该搜索信息或Master Information Block-SL message中,通过第一终端设备向第二终端设备广播时,广播该目标SI。

图6所示为根据本发明实施例的传输***信息的方法600的示意性流程图。
在610中,第一终端设备与第二终端设备建立通信连接。

在620中,第一终端设备获取第一指示信息。

在630中,第一终端设备接收基站广播的***信息。
可选的,在一些实施例中,基站向第一终端设备广播***信息时,该广播的***信息是以RRC消息的形式发送给第一终端设备的,其中,可以将MIB和SIB1分别以单独的RRC消息的形式向第一终端设备广播,将其他SIB则用若干条RRC消息向第一终端设备广播,即一条RRC消息可以携带多个其他的SIB。
在640中,第一终端设备从基站广播的***信息中提取目标SI。
可选的,在一些实施例中,第一终端设备可以根据获取的第一指示信息,从基站广播的***信息中提取目标SI。
在650中,第一终端设备生成RRC消息。
可选的,在一些实施例中,第一终端设备可以将目标SI或目标SI中的部分参数重构成RRC消息。
例如,在第二终端设备只具备基础的能力时,第二终端设备需要接收的***信息或***信息中的参数可以为:SIB1中的小区标识、小区禁止状态、小区为运营商保留状态、闭合用户群标识、闭合用户群指示、跟踪域编码、指示***信息是否改变的数值、允许类型0终端接入指示、公共陆地移动网标识列表、***信息有效时间等参数,以及SIB2中与接入控制相关参数,例如接入禁止因子、紧急呼叫接入禁止、移动端主叫呼叫接入禁止、移动端主叫信令接入禁止、特殊接入类禁止、接入禁止时间等参数,第一终端设备可以生成一条包含上述参数的RRC消息,使得第一终端设备不需要将SIB1 和SIB2中的第二终端设备不需要的其他参数发送给第二终端设备,减少了第一终端设备与第二终端设备之间的信令交互,避免了资源浪费,且有利于第一终端设备和第二终端设备节省电量。
又例如,支持SSAC能力的第二终端设备除了需要SIB1和SIB2中的上述参数之外,还需要SIB2中的SSAC相关参数,例如:(特定服务接入控制)多媒体视频业务接入禁止(ssac-Barring For MMTEL-video)和(特定服务接入控制)多媒体语音业务接入禁止(ssac-Barring For MMTEL-voice)等参数,此时,该第一终端设备可以将支持该SSAC能力的第二终端设备需要的SI中的一个或多个SIB和/或一个或多个SIB中的参数重构成一条RRC消息。

还例如,支持多媒体广播组播服务(Multimedia Broadcast Multicast Service,MBMS)能力的第二终端设备除了需要上述SIB1和SIB2中的参数之外,还需要SIB13和SIB15,此时,该第一终端设备可以将支持该MBMS能力的第二终端设备需要的SI中的一个或多个SIB和/或一个或多个SIB中的参数重构成一条RRC消息。
在660中,第一终端设备向第二终端设备发送RRC消息。
在第一终端设备根据第一指示信息从第二终端设备所需要的***信息中提取目标SI,并生成RRC消息之后,第一终端设备将该RRC消息发送给第二终端设备,该RRC消息中携带第二终端设备需要的所有或部分***信息,即目标SI。
可选的,在一些实施例中,第一终端设备可以是中继终端设备,例如,可以是智能手机等设备,第二终端设备可以是可穿戴设备,例如,可以是智能手表,智能手环等终端设备,但发明实施例并不限定于此。
在本发明实施例中,由于第一终端设备在生成RRC消息时,可以只提 取SIB中的部分参数并生成RRC消息,该部分参数为第二终端设备当前时刻需要的参数,所以第一终端设备不仅可以不向第二终端设备发送该第二终端设备不需要的***信息,还可以不向第二终端设备发送***信息中该第二终端设备不需要的部分参数,并且第一终端设备还可以将第二终端设备需要的多个***信息重构成一条RRC消息,这样更有利于减少了第一终端设备与第二终端设备之间的信令交互,降低信令开销,避免资源浪费,且有利于第一终端设备和第二终端设备的电量节省。
