Therefore, when the current motion speed of the terminal exceeds 80 km/s, the terminal maintains the existing network access status regardless of the strength of each system network covering the terminal, and does not perform handover. Therefore, when the terminal receives the handover instruction sent by the network side, the current motion vector of the acquisition terminal is described as the current motion speed of the terminal is 100 km/s, so the signal strength and the second mapping of the current various standard networks are obtained according to the measurement.

至此,已经按照其功能描述了移动终端。下面,为了简要起见,将描述诸如折叠型、直板型、摆动型、滑动型移动终端等等的各种类型的移动终端中的滑动型移动终端作为示例。因此,本发明能够应用于任何类型的移动终端,并且不限于滑动型移动终端。
如图1中所示的移动终端100可以被构造为利用经由帧或分组发送数据的诸如有线和无线通信***以及基于卫星的通信***来操作。
现在将参考图2描述其中根据本发明的移动终端能够操作的通信***。
这样的通信***可以使用不同的空中接口和/或物理层。例如,由通信***使用的空中接口包括例如频分多址(FDMA)、时分多址(TDMA)、码分多址(CDMA)和通用移动通信***(UMTS)(特别地,LTE)、GSM等等。作为非限制性示例,下面的描述涉及CDMA通信***,但是这样的教导同样适用于其它类型的***。
参考图2,CDMA无线通信***可以包括多个移动终端100、多个基站(BS)270、基站控制器(BSC)275和移动交换中心(MSC)280。MSC280被构造为与公共电话交换网络(PSTN)290形成接口。MSC280还被构造为与可以经由回程线路耦接到BS270的BSC275形成接口。回程线路可以根据若干已知的接口中的任一种来构造,所述接口包括例如E1/T1、ATM,IP、PPP、帧中继、HDSL、ADSL或xDSL。将理解的是,如图2中所示的***可以包括多个BSC275。
每个BS270可以服务一个或多个分区(或区域),由多向天线或指向特定方向的天线覆盖的每个分区放射状地远离BS270。或者,每个分区可以由用于分集接收的两个或更多天线覆盖。每个BS270可以被构造为支持多
个频率分配,并且每个频率分配具有特定频谱(例如,1.25MHz,5MHz等等)。
分区与频率分配的交叉可以被称为CDMA信道。BS270也可以被称为基站收发器子***(BTS)或者其它等效术语。在这样的情况下,术语"基站"可以用于笼统地表示单个BSC275和至少一个BS270。基站也可以被称为"蜂窝站"。或者,特定BS270的各分区可以被称为多个蜂窝站。
如图2中所示,广播发射器(BT)295将广播信号发送给在***内操作的移动终端100。如图1中所示的广播接收模块111被设置在移动终端100处以接收由BT295发送的广播信号。在图2中,示出了几个全球定位***(GPS)卫星300。卫星300帮助定位多个移动终端100中的至少一个。
在图2中,描绘了多个卫星300,但是理解的是,可以利用任何数目的卫星获得有用的定位信息。如图1中所示的作为GPS的位置信息模块115通常被构造为与卫星300配合以获得想要的定位信息。替代GPS跟踪技术或者在GPS跟踪技术之外,可以使用可以跟踪移动终端的位置的其它技术。另外,至少一个GPS卫星300可以选择性地或者额外地处理卫星DMB传输。
作为无线通信***的一个典型操作,BS270接收来自各种移动终端100的反向链路信号。移动终端100通常参与通话、消息收发和其它类型的通信。特定基站270接收的每个反向链路信号被在特定BS270内进行处理。获得的数据被转发给相关的BSC275。BSC提供通话资源分配和包括BS270之间的软切换过程的协调的移动管理功能。BSC275还将接收到的数据路由到MSC280,其提供用于与PSTN290形成接口的额外的路由服务。类似地,PSTN290与MSC280形成接口,MSC与BSC275形成接口,并且BSC275相应地控制BS270以将正向链路信号发送到移动终端100。
基于上述移动终端硬件结构以及通信***,提出本发明方法各个实施
例。
实施例一
参见图3,其示出了本发明实施例提供的一种终端切换网络的方法,该方法可以包括:
S301:当终端接收到网络侧下发的切换指令时,获取终端自身的终端状态信息;
S302:终端根据终端状态信息以及测量得到的当前各制式网络的状态信息匹配终端的历史统计状态与终端接入网络状态之间的映射关系,对终端切换网络进行决策。
需要说明的是,所述各制式网络的状态信息,具体包括:当前覆盖所述终端的各制式网络的信号强度。例如,网络制式可以包括LTE、WCDMA、GSM、CDMA、WIFI等等。所以,LTE信号强度信息包括:接收的信号强度指示(RSSI,Received Signal Strength Indication)、参考信号接收质量(RSRQ,ReferenceSignalReceivingQuality)、参考信号接收功率(RSRP,Reference Signal Receiving Power)、信噪比(SNR,Signal Noise Ratio);WCDMA信号强度统计信息包括:接收信号码功率(RSCP,Received Signal Code Power),每调制比特功率和噪声频谱密度的比率(Ec/No,Ratio of energy per modulating bit to the noise spectral density);GSM信号强度统计信息包括:RSSI;WIFI信号强度统计信息包括:RSSI。
在具体网络切换的实现过程中,网络侧会向终端发送切换指令使得终端从当前网络切换至待切换网络。但是,当终端处于相当多的场景时,待切换网络的网络质量并不能为终端的带来比当前网络更好的数据传输速率。例如,当前终端工作在LTE制式的移动通信网络,但是当LTE网络信号强度变弱满足了从LTE到WCDMA的切换条件的时候,实际上在LTE网络下的终端的数据业务性能仍旧比WCDMA更好,此时,对于终端来说,
继续处于当前的LTE网络才是最优的选择。举个例子,根据统计信息,LTE的参考信号接收功率(RSRP,Reference Signal Receiving Power)处于-95db至-110db,信噪比(SNR,Signal Noise Ratio)干扰较小的时候,数据性能仍然比WCDMA的接收信号码功率(RSCP,Received Signal Code Power)为-80db的时候数据性能要好。虽然此时满足了LTE切换至WCDMA的切换条件,但WCDMA网络无法为终端提供比LTE网络更好的数据业务性能。
此外,当用户处于各制式网络信号均较弱的情形时,例如当用户处于高速运动的列车上、或者楼宇中的公共卫生间的时候,此时,各制式网络的信号质量均较弱,终端会在不同制式的网络下频繁的切换,但是,由于各制式网络均不能提供较好的数据业务性能,因此,频繁的切换也无法提升终端的数据业务处理性能,所以,也没有必要对终端当前所处的网络进行切换。
除了以上两个具体情况之外,终端处于很多其他状态下,也并不需要对当前所处的网络进行切换,但是由于基站仅是根据信号强度等相关网络覆盖的恒定阈值指标进行切换命令的下发,无法针对终端实际所处情况进行是否切换的判定。因此,对于图1所示的技术方案,由于终端在接收到网络侧发送的切换指令之后,根据自身的终端状态主动地对终端切换网络进行决策,并非是被动的接收到切换指令就进行切换。所以,图1所示的技术方案能够在网络侧频繁发送的切换指令的时候,避免终端被动地依照切换指令进行网络切换,从而减少了终端用于网络切换时所耗费的电量。
示例性地,在本实施例中,所述获取所述终端自身的终端状态信息,具体包括:
所述终端通过GPS等定位***获取当前自身的位置信息;和/或,
所述终端通过加速度传感器及水平陀螺仪等传感器获取当前自身的运动状态信息。
可以理解地,上述的位置信息及运动状态信息均能够表征终端当前所处的状态,并且除了上述的两种信息以外,本领域技术人员还能够获取到其他类型的用于表征终端状态的信息,本实施例对此不做赘述。
相应地,在终端的历史统计状态与终端接入网络状态之间的映射关系中,终端的历史统计状态也可以是上述位置信息和运动状态信息的历史统计值。
因此,针对上述位置信息,可选地,参见图4,本发明实施例还可以包括:
S401:终端按照预设的激活频率周期性的通过GPS采集终端的历史位置信息;
S402:终端在采集终端的历史位置信息时,对应获取覆盖终端的各制式网络的第一历史状态;
S403:终端根据各制式网络的第一历史状态获取终端对应的第一接入网络的历史状态;
S404:终端构建历史位置信息、各制式网络的第一历史状态与第一接入网络的历史状态之间的第一映射关系。
在具体实现过程中,终端可以根据预设的激活频率,周期性地调用GPS获取历史位置信息,对历史位置信息周期性绘制成活动轨迹图;在采集终端的历史位置信息的同时,在活动轨迹上,对覆盖终端的各制式网络的第一历史状态进行获取,例如网络的信号强度信息等,并根据各制式网络的第一历史状态获取终端接入网络的状态;从而构建出历史位置信息、各制式网络的第一历史状态与对应的终端接入网络的历史状态之间的第一映射关系。
由此,当终端当前所处的位置处于历史运动轨迹中的某一位置时,终端就可以根据测量得到的当前各制式网络的状态信息与第一映射关系,确
定终端是否进行切换。
针对前述运动状态信息,可选地,参见图5,本发明实施例的方案还可以包括:
S501:终端在预设的时间窗口内记录自身的历史运动状态,并根据历史运动状态计算得到对应的历史运动矢量;
S502:终端在记录自身的历史运动状态时,对应获取覆盖终端的各制式网络的第二历史状态;
S503:终端根据各制式网络的第二历史状态获取终端对应的第二接入网络的历史状态;
S504:终端构建历史运动矢量、各制式网络的第二历史状态与第二接入网络的历史状态之间的第二映射关系。
在具体实现过程中,终端可以在预设的时间窗口内通过加速度传感器及水平陀螺仪等微机电***(MEMS,Microelectro Mechanical System)传感器获取自身在时间窗口内的历史运动状态,并且计算得到对应的历史运动矢量;在时间窗口内。终端对覆盖自身的各制式网络的第二历史状态进行获取,并得到终端对应的第二接入网络的历史状态;从而构建出历史运动矢量、各制式网络的第二历史状态与第二接入网络的历史状态之间的第二映射关系。
由此,当终端当前的运动状态信息满足历史运动矢量时,终端就可以根据测量得到的当前各制式网络的状态信息与第二映射关系,确定终端是否进行切换。
本实施例提供了一种终端切换网络的方法,在接收到网络侧发送的切换指令之后,终端根据自身的终端状态主动地对终端切换网络进行决策,并非是被动的接收到切换指令就进行切换,从而在网络侧频繁发送的切换指令的时候,避免终端被动地依照切换指令进行网络切换,从而减少了终
端用于网络切换时所耗费的电量。
实施例二
基于实施例一,参见图6,其示出了本发明实施例提供的一种终端切换网络的具体示例流程,可以包括:
S601:终端根据预设的激活频率周期性的通过GPS采集终端的历史位置信息;
S602:终端在采集终端的历史位置信息时,对应获取覆盖终端的各制式网络的第一历史信号强度;
S603:终端根据各制式网络的第一历史信号强度获取终端对应的第一接入网络的历史状态;
S604:终端构建历史位置信息、各制式网络的第一历史信号强度与第一接入网络的历史状态之间的第一映射关系;
需要说明的是,以上为终端设置第一映射关系的过程,使得终端后续能够根据当前的位置信息及第一映射关系对终端是否进行切换进行决策。
S605:当终端接收到网络侧下发的切换指令时,获取终端当前的位置信息;
S606:终端根据终端当前的位置信息以及测量得到的当前各制式网络的信号强度匹配第一映射关系,对终端切换网络进行决策。
例如,通过步骤S601至S604所得到的终端的第一映射关系表述为:当终端处于公共卫生间时,不管覆盖终端的各制式网络强度,终端均保持现有的网络接入状态,不进行切换。所以,当终端在接收到网络侧发送的切换指令时,获取得到当前的位置信息为公共卫生间,所以,根据测量得到的当前各制式网络的信号强度以及第一映射关系,终端均不会进行网络切换,仍然保持当前的网络接入状态。
又例如,通过步骤S601至S604所得到的终端的第一映射关系表述为:
当终端处于任何位置时,如果覆盖终端的LTE网络的RSRP处于-95db至-110db且覆盖终端的WCDMA网络的RSCP为-80db,那么终端仍然保持接入LTE网络。所以,当终端接收到网络侧发送的指示终端由LTE网络切换至WCDMA网络的切换指令时,终端当前测量得到的LTE网络的RSRP为-100db,WCDMA网络的为RSCP为-80db,终端根据第一映射关系确定不从当前所处的LTE网络切换至WCDMA网络。
实施例三
基于实施例一,参见图7,其示出了本发明实施例提供的另一种终端切换网络的具体示例流程,可以包括:
S701:终端在预设的时间窗口内通过加速度传感器及水平陀螺仪等MEMS传感器记录自身的历史运动状态,并根据历史运动状态计算得到对应的历史运动矢量;
S702:终端在记录自身的历史运动状态时,对应获取覆盖终端的各制式网络的第二历史信号强度;
S703:终端根据各制式网络的第二历史信号强度获取终端对应的第二接入网络的历史状态;
S704:终端构建历史运动矢量、各制式网络的第二历史信号强度与第二接入网络的历史状态之间的第二映射关系;
需要说明的是,以上为终端设置第二映射关系的过程,使得终端后续能够根据当前的运动矢量及第二映射关系对终端是否进行切换进行决策。
S705:当终端接收到网络侧下发的切换指令时,获取终端当前的运动矢量;
S706:终端根据终端当前的运动矢量以及测量得到的当前各制式网络的信号强度匹配第二映射关系,对终端切换网络进行决策。
例如,通过步骤S701至S704所得到的终端的第二映射关系可以表述
为:当终端当前的运动速度超过80km/s时,不管覆盖终端的各制式网络强度,终端均保持现有的网络接入状态,不进行切换。所以,当终端在接收到网络侧发送的切换指令时,获取终端当前的运动矢量描述为终端当前的运动速度为100km/s,所以,根据测量得到的当前各制式网络的信号强度以及第二映射关系,终端均不会进行网络切换,仍然保持当前的网络接入状态。
