本发明实施例提供了一种网络搜索控制方法与设备,用于缩小移动通信终端在搜索网络时的搜索范围,节省网络搜索时间,提高效率。以下分别进行详细说明。
本发明实施例中,终端设备可以是各种移动通信终端设备,包括手机、平板电脑、个人数字助理(Personal Digital Assistant,PDA)、销售终端(Point of Sales,POS)、车载电脑等,本发明实施例后续不作复述。
图1是本发明实施例公开的一种网络搜索控制方法的流程示意图。其中,图1所示的网络搜索控制方法可以包括以下步骤:
101、获取网络设备支持的第一网络接入能力;
本发明实施例中,网络设备可以为移动网络运营商所运行维护的网络鉴权中心,或是其他能判断网络允许终端设备接入能力的设备,本发明实施例不作限定。
作为一种可选的实施方式,在获取网络设备支持的第一网络接入能力之前,终端设备向网络鉴权中心发送终端设备的卡系统识别信息进行鉴权。该鉴权过程用于网络鉴权中心确认该用户具有权利接入网络,避免非法用户占用网络资源;同时,鉴权过程防止用户被接入非法的网络而导致被骗取关键信息。
上述用于鉴权的卡系统识别信息包括:
集成电路卡识别码(integrate circuit card identity,ICCID)和国际移动用户识别码(international mobile subscriber identification number,IMSI),鉴权过程成功后,网络鉴权中心根据ICCID和IMSI,从数据库查询允许该卡系统接入的网络制式,作为第一网络接入能力发送给终端设备。
上述第一网络接入能力由移动网络运营商进行维护,例如:用户欠费时,将不能使用该移动网络运营商的服务,移动网络运营商将第一网络接入能力设置为不能接入。
102、获取上述终端设备支持的第二网络接入能力;
本发明实施例中,可以获取终端设备的卡系统支持的网络制式,将卡系统支持的网络制式作为上述终端设备支持的第二网络能力。
用于获取卡系统支持的网络制式的信息包括:
ICCID,主要用于判断移动网络运营商,例如:移动、联通、电信等。
卡类型,例如:客户识别模块(subscriber indentifymodule,SIM)卡,SIM卡最高可支持的网络制式为3G;全球用户识别模块(Universal Subscriber Indentify Module,USIM)卡,USIM卡最高可支持的网络制式为4G;
综合ICCID和卡类型信息,即可得出该卡系统支持的网络制式。
作为一种可选的实施方式,可采用单个字节数值的形式表示上述第一网络接入能力和第二网络接入能力。单个字节的前6个比特位分别对应1种网络制式,若比特位为1则表示支持对应的网络制式,若比特位为0则表示不支持对应的网络制式,后2个比特位保留;如表1所示,表1为一种网络制式与比特位对应关系示例:
表1
Bit位 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
网络制式 | 保留 | 保留 | LTE | TD-SCDMA | WCDMA | EVDO | CDMA | GSM |
103、获取目标网络制式,将该目标网络制式作为需要搜索的网络制式。
本发明实施例中,将第一网络接入能力和第二网络接入能力均支持的网络制式,作为目标网络制式。
作为一种可选的实施方式,通过步骤102得到第一网络接入能力和第二网络接入能力的单字节数值表示之后,将第一网络接入能力和第二网络接入能力分别对应的单个字节进行按位与操作,得到第一目标字节,确定第一目标字节前6个比特位中为1的比特位对应的网络制式为目标网络制式。该目标网络制式即为需要搜索的网络制式。

207、获取不支持的网络制式,并输出上述不支持的网络制式的提示信息。
本发明实施例中,用户设置的网络制式可能与上述需要搜索的网络制式不完全相同,可以通过比较第三网络接入能力和目标网络制式之间的不同,得到不支持的网络制式。
作为一种可选的实施方式,通过步骤205得到第三网络接入能力的单字节数值表示和第一目标字节之后,将第三网络接入能力对应的字节和第一目标字节进行异或操作,得到第二目标字节;确定第二目标字节前6个比特位中为1的比特位对应的网络制式为不支持的网络制式,并输出上述不支持的网络制式的提示信息。
