附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案,下面将对实施例中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是 本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动性的前提下,还可以根据这些附图获得其他的附图。
图1为本发明的基于eHRPD网络切换LTE网络的方法实施例1的流程图;
图2为本发明的基于eHRPD网络切换LTE网络的方法实施例2的流程图;
图3为本发明的基于eHRPD网络切换LTE网络的方法实施例3的流程图;
图4为本发明的基于eHRPD网络切换LTE网络的系统实施例的结构图。
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,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他实施例,都属于本发明保护的范围。
为使本发明的上述目的、特征和优点能够更加明显易懂,下面结合附图和具体实施方式对本发明作进一步详细的说明。
图1为本发明的基于eHRPD网络切换LTE网络的方法实施例1的流程图。首先需要说明的是。eHRPD,英文全称为evolution High Rate Packet data,中文含义为演进的高速分组数据。LTE,英文全称为Long Term Evolution,中文含义为长期演进。本发明中提到的4G网络可以是LTE网络。而eHRPD网络是CDMA技术中,向LTE网络演进的一种过渡技术。因此,将移动终端从eHRPD网络切换至LTE网络,可以提高移动终端的数据传输速度,使用户连接到4G网络,提高用户体验。
如图1所示,本发明的基于eHRPD网络切换LTE网络的方法可以包括:
步骤101:处于eHRPD网络中的移动终端按照第一时间间隔搜索LTE网络;
所述移动终端可以是手机,或者其它具有通信芯片的电子设备。
所述第一时间间隔可以是预先设置的初始时间间隔,也可以是经过计算得到的适用于本次网络信号搜索过程的时间间隔。
当所述第一时间间隔是预先设置的初始时间间隔时,所述第一时间间隔可 以是30秒,1分钟或2分钟等等。
假设所述第一时间间隔为1分钟,则可以表示从本次网络搜索周期开始计时,当计时时间达到1分钟时,执行搜索操作。
步骤102:判断是否搜索到LTE网络,得到第一判断结果;
LTE网络信号的频点,与eHRPD网络信号的频点不同。搜索LTE网络信号时,可以对LTE网络信号的频点依次进行扫描,判断各个频点上是否接收到LTE网络信号,如果接收到LTE网络信号,则可以进一步判断该LTE网络信号的信号强度是否足够进行正常通信。如果信号强度足够,则可以得到表示肯定的第一判断结果。
可以采用特定标识表示是否搜索到LTE网络。例如,可以采用标识“0”表示未搜索到LTE网络,采用标识“1”表示搜索到了LTE网络。
步骤103:当所述第一判断结果表示未搜索到LTE网络时,获取所述eHRPD网络的网络状态信息;
所述eHRPD网络的网络状态信息,可以表示eHRPD网络的通信质量。具体的,可以采用接收信号强度指示值(Received Signal Strength Indication,RSSI)作为eHRPD网络的网络状态信息。如果RSSI的数值较大,则表示网络状态较好;反之,表示网络状态较差。
步骤104:基于所述网络状态信息与所述第一时间间隔,确定第二时间间隔;所述第二时间间隔大于所述第一时间间隔;
具体的,基于所述网络状态信息与所述第一时间间隔,确定第二时间间隔,可以包括以下情况:
当所述网络状态信息表示所述eHRPD网络的网络状态较好时,在所述第一时间间隔的基础上增加第一预设时长,得到第二时间间隔;
当所述网络状态信息表示所述eHRPD网络的网络状态较差时,在所述第一时间间隔的基础上增加第二预设时长,得到第二时间间隔;
其中,所述第一预设时长大于所述第二预设时长。
因为,当所述eHRPD网络的网络状态较好时,所述移动终端在被用户使用时所呈现出的性能(例如数据下载速度)也是较好的,所以,此时即使移动终端在较长时间内处于eHRPD网络中,用户的使用感受也不会太差。因此, 可以将网络搜索时间间隔(即第二时间间隔)设置的长一些,从而降低移动终端搜索LTE网络所产生的功耗。当所述eHRPD网络的网络状态较差时,所述移动终端在被用户使用时所呈现出的性能(例如数据下载速度)也是较差的,所以,此时需要尽快将移动终端切换至LTE网络中,但为了确保移动终端的功耗不会过高,故采用在所述第一时间间隔的基础上增加第二预设时长的方式,得到第二时间间隔。
步骤105:按照所述第二时间间隔搜索LTE网络。
综上所述,本实施例中,通过按照第一时间间隔搜索LTE网络;当未搜索到LTE网络时,获取所述eHRPD网络的网络状态信息;基于所述网络状态信息与所述第一时间间隔,确定第二时间间隔;所述第二时间间隔大于所述第一时间间隔;按照所述第二时间间隔搜索LTE网络;可以调整搜索网络信号的时间间隔,降低搜索网络信号所消耗的总体功耗,从而延长移动终端的续航时间。
图2为本发明的基于eHRPD网络切换LTE网络的方法实施例2的流程图。如图2所示,该方法可以包括:
步骤201:按照第一时间间隔搜索LTE网络;
步骤202:判断是否搜索到LTE网络,得到第一判断结果;
步骤203:当所述第一判断结果表示未搜索到LTE网络时,获取所述eHRPD网络的接收信号强度指示实测值。
本实施例中,采用接收信号强度指示(RSSI)值来描述所述eHRPD网络的网络状态信息。可以采用最近一次测量得到的RSSI值,作为接收信号强度指示实测值。
步骤204:基于所述网络状态信息与所述第一时间间隔,根据公式Tcurrent=Tprev(1+R/Rcurrent),确定第二时间间隔;
其中,Tcurrent表示所述第二时间间隔,Tprev表示所述第一时间间隔,Rcurrent表示所述接收信号强度指示实测值,R表示接收信号强度指示标准值。
实际应用中,所述接收信号强度指示标准值可以设置为-80dbm。
步骤205:按照所述第二时间间隔搜索LTE网络。
按照本实施例中的公式,假设第一时间间隔为1分钟,接收信号强度指示 实测值为-40dbm,则Tcurrent=1*[1+(-80)/(-40)],可以算得Tcurrent为3分钟。假设第一时间间隔为1分钟,接收信号强度指示实测值为-100dbm,则Tcurrent=1*[1+(-80)/(-100)],可以算得Tcurrent为1.8分钟。
由上述可知,本实施例中,通过根据公式Tcurrent=Tprev(1+R/Rcurrent),确定第二时间间隔;其中,Tcurrent表示所述第二时间间隔,Tprev表示所述第一时间间隔,Rcurrent表示所述接收信号强度指示实测值,R表示接收信号强度指示标准值;可以综合考虑所述网络状态信息与所述第一时间间隔,确定第二时间间隔;当eHRPD的网络状态较好时,可以确定出一个较长的第二时间间隔,从而适当延长搜索时间,在不影响用户的使用体验的前提下进一步降低移动终端的功耗;当eHRPD的网络状态较差时,可以确定出一个较短的第二时间间隔,从而尽快将移动终端切换至LTE网络,从而提高移动终端的网络性能,提升用户体验。
图3为本发明的基于eHRPD网络切换LTE网络的方法实施例3的流程图。如图3所示,该方法可以包括:
步骤301:按照第一时间间隔搜索LTE网络;
步骤302:判断是否搜索到LTE网络,得到第一判断结果;
步骤303:当所述第一判断结果表示未搜索到LTE网络时,获取所述eHRPD网络的接收信号强度指示实测值。
步骤304:基于所述网络状态信息与所述第一时间间隔,根据公式Tcurrent=Tprev(1+R/Rcurrent),确定第二时间间隔;
其中,Tcurrent表示所述第二时间间隔,Tprev表示所述第一时间间隔,Rcurrent表示所述接收信号强度指示实测值,R表示接收信号强度指示标准值。
实际应用中,所述接收信号强度指示标准值可以设置为-80dbm。
步骤305:判断所述第二时间间隔是否大于预设时间间隔上限,得到第二判断结果;
所述预设时间间隔上限,可以根据实际需求进行设置。例如,可以将所述预设时间间隔上限设置为5分钟。即,当计算得到的第二时间间隔大于5分钟时,将得到表示肯定的第二判断结果。
步骤306:当所述第二判断结果表示所述第二时间间隔大于预设时间间隔 上限时,将所述第二时间间隔重置为初始时间间隔。
步骤307:按照所述第二时间间隔搜索LTE网络。
当所述第二时间间隔大于预设时间间隔上限时,通常会导致搜索时间间隔过长,从而延误将移动终端切换至LTE网络的时机。因此,本实施例中,当所述第二时间间隔大于预设时间间隔上限时,将所述第二时间间隔重置为初始时间间隔,所述初始时间间隔小于或等于所述第一时间间隔,可以避免第二时间间隔过长,进一步可以避免第二时间间隔过长导致的延误将移动终端切换至LTE网络的时机。
还需要说明的是,本发明各个实施例中,当所述第一判断结果表示搜索到LTE网络时,均可以执行以下步骤:将所述移动终端切换至搜索到的所述LTE网络。
