Description

一种搜网的方法及装置 技术领域
本文涉及但不限于通信领域，具体涉及一种搜网的方法及装置。
背景技术
手机终端漫游到异地(或异国)网络，当地的移动通信网络相对归属地的网络发生变化，甚至会出现制式的区别，比如从GW网络(GSM网络、或WCDMA网络)漫游到C网(CDMA*EVDO)，归属地支持的小区切换技术不足以支持网络的无缝切换。当手机终端漫游在异地或异国网络时，手机终端会出现无服务状态，在无服务状态开始终端由于难以判断是否进入漫游区而无法采取更好的搜网策略，只能盲目的全频搜索网络。
相关技术中，盲目的全频搜索网络指的是对终端和客户识别模块SIM/通用客户识别模块USIM卡支持的全频段进行搜索，直到找到与终端归属地网络运营商签署漫游协议的网络小区。这个过程耗时较长(比如归属地是C网，与归属地签署协议的漫游区域网络为GW网，假如终端按长期演进LTE、C、GW网的优先级搜网，要花很长时间才能搜索到漫游网络；即便归属地网络和漫游网络是同一网络制式，也要搜索该制式的全部频段才能注册到漫游网络)，用户体验不好。

至此，己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，本发明实施例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系统以及基于卫星的通信系统来操作。
现在将参考图2描述其中根据本发明实施例的移动终端能够操作的通信系统。
这样的通信系统可以使用不同的空中接口和/或物理层。例如，由通信系统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)和通用移动通信系统(UMTS)(特别地，长期演进(LTE))、全球移动通信系统(GSM)等等。作为非限制性示例，下面的描述涉及CDMA通信系统，但是这样的教导同样适用于其它类型的系统。
参考图2，CDMA无线通信系统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基站270的BSC275形成接口。回程线路可以根据若干己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中所示的系统可以包括多个BSC2750。
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，每个分区可以由设置为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系统(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系统内操作的移 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系统(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GPS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。
作为无线通信系统的一个典型操作，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系统，提出本发明方法各个实施例。

实施例二
下面结合具体场景进一步说明本发明实施例的技术方案。
本发明实施例根据终端设备的GPS信息确定待搜索网络，然后根据该待搜索网络进行网络搜索，从而大大提高了网络搜索的速率。
假设以下场景中终端设备归属地为A，终端设备签署漫游协议的地区或国家包括B、C、D。终端设备是在开机状态下切换地点。
场景一
如图4所示，该场景中终端设备开机状态下从A到B，也就是从归属地到漫游区域。
1)终端设备从A移动到B后，当终端设备开始搜索网络时，根据该终端设备的GPS信息确定终端设备当前的地理位置；然后根据漫游区域和/或归属地的地理位置确定该终端设备当前位于漫游区域；
2)然后终端设备根据该漫游区域B与归属地A网络运营商签署漫游协议的网络确定区域B对应的网络；
3)然后终端设备按照区域B对应的网络进行网络搜索。
该场景中优先搜索漫游区域B的网络，不必全频段搜索，因此大大提高了搜网的速度，使终端设备快速注册到漫游区域的网络。
场景二
如图5所示，该场景中终端设备开机状态下从C到A，也就是从漫游区域到归属地。
1)终端设备从C移动到A后，当终端设备开始搜索网络时，根据该终端设备的GPS信息确定终端设备当前的地理位置；然后根据漫游区域和/或归属地的地理位置确定该终端设备当前位于归属地；
2)然后终端设备根据该终端设备归属地的公共陆地移动网络Public (Home Land Mobile Network，HPLMN)进行网络搜索。
该场景中根据GPS信息判断出不是漫游，从而优先搜HPLMN，使得终端设备可以快速注册到HPLMN。
实施例三
终端设备开机时，通常采取RPLMN优先的原则搜网。在本发明实施例中，当终端设备开机搜索网络时，需要根据RPLMN以及终端设备当前所处的地区的网络对RPLMN进行相应的处理。
假设以下场景中终端设备归属地为A，终端设备签署漫游协议的地区或国家包括B、C、D。终端设备关机后切换地点。
场景一
如图6所示，终端设备在A关机，然后再A开机，也就是归属地关机，归属地开机。
该场景下RPLMN属于HPLMN，并且根据GPS信息确定终端设备不是漫游，此时不修改RPLMN，当终端设备开机搜索网络时直接用原有RPLMN进行网络搜索。
场景二
如图7所示，终端设备在B关机，然后在A开机，也就是漫游区域关机，归属地开机。
该场景下RPLMN不属于HPLMN，并且根据GPS信息确定终端设备不是漫游，此时不能直接使用原来的RPLMN，而是需要先将RPLMN修改为HPLMN，然后使用HPLMN进行网络搜索。
场景三
如图8所示，终端设备在A关机，然后在C开机，也就是归属地关机，漫游区域开机。
该场景下RPLMN属于HPLMN，并且根据GPS信息确定终端设备是漫 游，此时不能直接使用原来的RPLMN，而是需要先将RPLMN修改为C签署的漫游协议中指定的网络，然后使用C签署的漫游协议中指定的网络进行网络搜索。
场景四
如图9所示，终端设备在C关机，然后在B开机，也就是一个漫游区域关机，另一个漫游区域开机。
该场景下RPLMN不属于HPLMN，并且根据GPS信息确定终端设备是漫游，同时终端设备当前的漫游区域和RPLMN对应的漫游区域不同，此时不能直接使用原来的RPLMN，而是需要先将RPLMN修改为B签署的漫游协议中指定的网络，然后使用B签署的漫游协议中指定的网络进行网络搜索。
场景五
如图10所示，终端设备在B关机，然后在B开机，也就是漫游区域关机，在相同漫游区域开机。
该场景下RPLMN不属于HPLMN，并且根据GPS信息确定终端设备是漫游，同时终端设备当前的漫游区域和RPLMN对应的漫游区域相同，此时可以不修改RPLMN，直接使用原来的RPLMN进行网络搜索。
上述场景通过GPS信息确定待搜索网络，可以大大提高网络搜索的速度，使终端设备很快注册到网络。
