本公开涉及通信技术领域，尤其涉及网络选择方法及装置。
背景技术
对于支持多模的移动终端，一般都可以驻留到4G/3G/2G等不同模式的网络上。以手机为例，由于拥塞、信号较弱等原因，可能会出现手机从最优先的LTE(Long Term Evolution，长期演进)网络回落到3G/2G网络的情况。在相关技术中，例如3GPP(3rd Generation Partnership Project，第三代移动通信标准化伙伴项目)中，规定：如果测量到比当前网络有更高优先级的网络，移动终端需要重新回到更高优先级的网络。然而问题在于，在一些情况下，网络侧可能未提供优先级指示，此时当移动终端驻留在优先级实质上较低的网络时，若当前网络情况较好，不满足发生重选的条件，则即使存在优先级实质上更高的网络，移动终端也不会较快地返回该优先级实质上更高的网络。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
本文中的移动终端可以是手机、平板电脑、电子书阅读器、MP3(Moving Picture Experts Group Audio Layer III，动态影像专家压缩标准音频层面3)播放器、MP4(Moving Picture Experts Group Audio Layer IV，动态影像专家压缩标准音频层面4)播放器和膝上型便携计算机等等。
图1是根据一示例性实施例示出的一种网络选择方法的流程图。该方法可用于手机等移动终端。参见图1所示，该方法可以包括：
在步骤S101中，当移动终端无法驻留在最优先网络时，记录下当前无法驻留的最优先网络的小区，其中所述最优先网络根据所述移动终端中预置的规则确定。
在本实施例中，移动终端在判断搜索到的某网络的优先级时，摆脱了对网络侧的依赖，即无需根据网络侧对优先级的指示，而是根据自身预置的规则就可确定该网络是否为最优先网络。
对于该预置的规则的内容本实施例并不进行限制，如可规定2G、3G、4G的优先级逐渐升高，4G为最优先网络。可以在此处使用的这些规则都没有背离本公开的精神和保护范围。
作为示例，该预置的规则可以包括：
将所述移动终端所归属的长期演进LTE网络定义为所述最优先网络。
本实施例中移动终端先是驻留在最优先网络的某小区，当因为某些原因，例如CSFB(Circuit Switched Fallback，电路域回落)、信号弱覆盖、拥塞、网络问题等，移动终端无法驻留在最优先网络时，本实施例中移动终端在离开前或离开后亦或离开时，会对该小区进行记录。例如可以记录该小区的标识、离开的原因等等，对于记录的内容本实施例并不进行限制。
在步骤S102中，在移动终端驻留在非最优先网络时对所述最优先网络进行监测。
移动终端不得不离开最优先网络而驻留在非最优先网络后，会对最优先网络进行监测，以便在条件成熟时可以及时返回最优先网络。
在步骤S103中，若监测到所述最优先网络的小区，且所述监测到的小区与先前记录下的小区之间的关系满足预设条件，则执行步骤S104。
而如果未监测到最优先网络的小区，或者监测到最优先网络的小区但该小区与先前记录下的小区之间的关系并不满足预设条件，则不执行步骤S104，例如可以继续使移动终端驻留在当前所在的非最优先网络。
在步骤S104中，无论所述移动终端当前的网络连接状态是否处于空闲态，均将所述移动终端切换至所述监测到的小区。
作为示例，在本实施例或本公开的其它可选实施例中，所述预设条件可以包括：
i)所述监测到的小区不属于所述先前记录下的小区。
如果将先前记录下的小区称为旧小区的话，那么监测到的小区则可称为新小区。作为示例可参见图2所示，在图2中203为移动终端，小区201为旧小区，小区202为新小区，这两个小区是不同的小区，移动终端203先是在旧小区201中，后来移动到新小区202中。
先前移动终端不得不离开旧小区时，旧小区存在拥塞等问题，故应该回避该旧小区，而当前如果发现的新小区已经不是旧小区了，那么将所述移动终端切换至新小区以使移动终端尽快回到最优先网络也是合理的。此外容易理解的是，对于新小区万一也存在拥塞等问题这类小概率情况，不在本公开所讨论的范围内。
作为示例，在本实施例或本公开的其它可选实施例中，所述预设条件也可以包括：
ii)所述监测到的小区属于所述先前记录下的小区，且当前时刻与离开所述记录下的小区的时刻的间隔超过了预设时长。
预设时长也可称为回避时长。如果监测到的小区是旧小区，但当前时刻与离开旧小区的时刻的间隔时长已经足够长，即已超过预设时长，则有理由相信旧小区的拥塞等问题应该已经解决，不需要再回避，所以当前将所述移动终端切换回旧小区以使移动终端尽快回到最优先网络也是合理的。
对于预设时长的长度本实施例并不进行限制，本领域技术人员可以根据不同场景进行预设，例如可以设为5分钟或10分钟等。此外容易理解的是，对于过了预设时长后旧小区万一仍然存在拥塞等问题这类小概率情况，不在本公开所讨论的范围内。
此外，对于其他一些特殊情况，例如同时监测到至少两个最优先网络小区，而且既包括新小区又包括满足预设时长要求的旧小区，则此时将这些小区按照信号强度、通信质量等因素排序后择优选取其中一个，作为要驻留的小区，不再赘述。
参见图3所示，在本实施例或本公开的其它可选实施例中，所述步骤104可以包括：
在步骤S1041中，若所述移动终端的当前网络连接状态处于空闲态，则将所述移动终端的网络模式切换到所述最优先网络，并向所述监测到的小区发起注册请求，以驻留在所述最优先网络；
在步骤S1042中，若所述移动终端的当前网络连接状态处于连接态，则发起PLMN(Public Land Mobile Network，公共陆地移动网络)选择，将所述移动终端的网络模式切换到所述最优先网络，并向所述监测到的小区发起注册请求，以驻留在所述最优先网络。
发起PLMN选择是移动终端对自身底层模块的命令，若移动终端的当前网络连接状态处于连接态，此时发起PLMN选择相当于强制断网，然后进行网络重选。而在相关技术中，当处于连接态时通常是不会进行强制断网的。
在本实施例中，当移动终端由于某些原因而无法驻留在最优先网络时，移动终端会记 录下当前无法驻留的最优先网络的小区，其中所述最优先网络根据所述移动终端中预置的规则确定；而后若监测到所述最优先网络的小区，且所述监测到的小区与先前记录下的小区之间的关系满足预设条件，则无论所述移动终端当前的网络连接状态是否处于空闲态，均将所述移动终端切换至所述监测到的小区。由于在本实施例中，移动终端可以不依靠网络侧的指示就能获知当前网络是否是最优先网络，摆脱了对网络侧的依赖，使移动终端在网络侧未提供优先级指示的情况下快速回到优先级实质上更高的网络成为了可能；同时，通过对已离开的最优先网络小区的记录以及对监测到的最优先网络新小区的判断，使移动终端可以确定当前是否可以返回最优先网络，并在确定之后强迫自身返回最优先网络，从而使得移动终端在网络侧未提供优先级指示的情况下快速回到优先级实质上更高的网络最终得以实现。
图4是根据一示例性实施例示出的一种网络选择方法的流程图。参见图4所示：
在步骤S401中，移动终端接收对最优先网络的定义规则。
例如，移动终端可以在出厂时接收该规则，使之预置在移动终端中；也可以在使用过程中由用户通过操作在移动终端中定义该规则。
在步骤S402中，移动终端驻留在最优先网络。
在步骤S403中，某时刻，移动终端发现已无法驻留在最优先网络上。例如可以是由于CSFB、信号弱覆盖、拥塞、网络问题等原因而导致无法驻留。
在步骤S404中，移动终端记录下所离开的最优先网络的小区。
在步骤S405中，移动终端驻留到非最优先网络，同时对最优先网络进行监测。
在步骤S406中，移动终端判断是否监测到最优先网络下的小区，如果监测到则进入步骤S407，如果未监测到则返回步骤S405。
在步骤S407中，移动终端判断所监测到的小区是否是新小区，或者如果所监测到的小区是先前记录下的旧小区但当前是否已经过了回避时长。
如果所监测到的小区是新小区，或者所监测到的小区是先前记录下的旧小区但当前已经过了回避时长，则进入步骤S408，否则则返回步骤S405。
在步骤S408中，移动终端判断自身当前网络连接状态是否是空闲态。如果是空闲态则进入步骤S409，如果不是空闲态则进入步骤S410。
在步骤S409中，移动终端将自身网络模式切换到所述最优先网络，并向所述监测到的小区发起注册请求，以驻留在所述最优先网络。然后返回步骤S402。
在步骤S410中，移动终端发起PLMN选择，将所述移动终端的网络模式切换到所述最优先网络，并向所述监测到的小区发起注册请求，以驻留在所述最优先网络。然后返回步骤S402。
在本实施例中，当移动终端由于某些原因而无法驻留在最优先网络时，移动终端会记录下当前无法驻留的最优先网络的小区，其中所述最优先网络根据所述移动终端中预置的 规则确定；而后若监测到所述最优先网络的小区，且所述监测到的小区与先前记录下的小区之间的关系满足预设条件，则无论所述移动终端当前的网络连接状态是否处于空闲态，均将所述移动终端切换至所述监测到的小区。由于在本实施例中，移动终端可以不依靠网络侧的指示就能获知当前网络是否是最优先网络，摆脱了对网络侧的依赖，使移动终端在网络侧未提供优先级指示的情况下快速回到优先级实质上更高的网络成为了可能；同时，通过对已离开的最优先网络小区的记录以及对监测到的最优先网络新小区的判断，使移动终端可以确定当前是否可以返回最优先网络，并在确定之后强迫自身返回最优先网络，从而使得移动终端在网络侧未提供优先级指示的情况下快速回到优先级实质上更高的网络最终得以实现。
