Description

终端的搜网方法和终端 技术领域
本发明涉及通信技术，尤其涉及一种终端的搜网方法和终端。
背景技术
随着通信技术的进步，各种通信终端也快速的发展起来。由于移动终端的便利性，发展尤其快速。在现有技术中，为保证移动终端能够正常的使用各种业务，需要依赖于运营商提供的网络，即该移动终端在使用的时候必须处于一个有网络覆盖的地方。但在现有的网络下，并不是所有的地方都被网络覆盖，在一些室内封闭的地区，如电梯、地下室等，或者室外的网络覆盖盲点，如建筑物密集地区、偏远山区等地方网络覆盖都较差。一旦移动终端处于非网络覆盖或丢失网络的地方，移动终端需要尝试进行网络搜索，来重新获取网络。
现有技术中，终端掉网后进行搜网的流程采用二层结构，即：首先执行历史频点搜网，然后执行全频段搜网，其中，历史频点搜网是指搜索手机存储的曾经驻留过的频点信息，全频段搜网是指搜索手机所支持的所有频段。并且，现有技术中，执行历史频点搜网的频率和执行全频段搜网的频率是相同的，例如：终端掉网后，在历史频点上搜一次，然后全频段再搜一次，终端在历史频点和全频段搜网是基于相同的频率进行搜索的。可以理解的，历史频点搜网更容易搜到可用网络且执行历史频点搜网的时间短，全频段搜网的时间长。
但是，当终端从无网络环境进入网络覆盖环境中时，现有技术的搜网方案经常会导致终端无法快速的搜到可用频点，并且，搜网时间较长，终端的功耗过大。

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，下面将对实施例或现有技术描述中所需要使用的附图作一简单地介绍，显而易见地，下面描述中的附图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的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，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作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。
本发明实施例涉及的终端，即用户设备，可以是无线终端也可以是有线终端。无线终端包括向用户提供语音和/或数据服务的设备，可选的，该设备可以为具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。并且，该无线终端还可以经无线接入网(例如，RAN，Radio Access Network)与一个或多个核心网进行通信，例如该无线终端具体可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，该具有移动终端的计算机可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们可以与核心网进行语音和/或数据的交互。
在现有技术中，终端执行历史频点搜网的频率和执行全频段搜网的频率相同，执行全频段搜网的时间比执行历史频点搜网的时间长，执行全频段搜网的功耗比执行历史频点搜网的功耗大。当终端从无网络环境进入网络覆盖 环境时，终端按照现有技术的方法执行搜网，如果在执行历史频点搜网时，没有搜索到网络，那么，终端就会执行一次时间相对较长、功耗相对较大的的全频段搜网。本发明实施例提供的方法，用以解决现有技术的上述技术问题。
下面以具体地实施例对本发明的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。
图1为本发明实施例提供的终端的搜网方法的流程示意图。该方法的执行主体可以为终端，该终端预设有定时器集合，所述定时器集合包括第一定时器和第二定时器，所述第一定时器的时长小于所述第二定时器的时长。如图1所示，该方法包括：
S101：确定所述终端超时定时器的类型；其中，所述超时定时器的类型包括第一定时器或第二定时器。
具体的，终端在网络覆盖较好的环境下，一般是通过某一个频点搜索到网络后，并在确定该网络的网络门限是终端能够驻留的门限，终端才会驻留在该网络上，并与该网络中的某些网元进行信令或数据交互。当终端处于无网络覆盖区时，终端处于掉网状态，若终端从无网络覆盖区移动至网络覆盖区时，终端在预设的时间内会启动搜网流程。本实施例中，当终端从无网络覆盖区移动至网络覆盖区时，终端在预设的时间内启动终端预设的定时器，并在所启动的定时器超时时，确定该超时定时器的类型为第一定时器还是第二定时器。可选的，由于定时器是通过软件预置在终端中的，因此，终端可以通过执行相应的软件线程获知当前超时定时器类型是第一定时器还是第二定时器。需要说明的是，本发明实施例对终端确定超时定时器的类型的方式并不做限定。
S102：根据所述超时定时器的类型和关联关系，确定所述终端的搜网方式；其中，所述关联关系为所述终端的搜网方式与所述定时器集合中的定时器的映射关系，且所述关联关系中所述第一定时器对应的所述终端的搜网方式为历史频点搜网，所述第二定时器对应的所述终端的搜网方式为全频段搜网。
S103：触发所述终端根据所述确定的搜网方式进行搜网。
具体的，终端可以根据当前超时的定时器的类型和上述关联关系确定应该执行历史频点搜网还是全频段搜网。另外，可以根据执行历史频点搜网的时长设置第一定时器的时长，根据执行全频段搜网的时长设置第二定时器的时长，可选的，第一定时器的时长等于历史频点搜网从开始到结束的时长，第二定时器的时长等于全频段搜网从开始到结束的时长。由于终端根据不同时长的定时器执行不同的搜网方式(历史频点搜网或全频段搜网)，即，历史频点搜网对应的第一定时器的时长小于全频段搜网对应的第二定时器的时长，而且，历史频点搜网的方式时间短；所以，根据本发明实施例提供的方案，在一段时间内，终端执行历史频点搜网的次数大于执行全频段搜网的次数。并且，由于相应减少了终端执行全频段搜网的次数，从而降低了终端的功耗并加快了网络恢复的速度。
需要说明的是，本实施例涉及的历史频点指的是终端曾经通过这个频点驻留到网络上的频点，本实施例涉及的全频段指的是终端支持的所有频段，例如终端支持GSM制式、WCDMA制式和LTE制式，则全频段就包括全球移动通信***(Global System for Mobile Communication，以下简称GSM)制式、宽带码分多址(Wideband Code Division Multiple Access，以下简称WCDMA)制式和长期演进(Long Term Evolution，以下简称LTE)制式分别对应的频段信息。
可选的，终端可以在从无网络覆盖区移动至网络覆盖区的过程中获取终端的搜网方式与定时器集合中的定时器之间的关联关系，还可以是用户在终端内部的存储器中预置该关联关系，待终端需要使用该关联关系时，采用相应的软件从存储器中调用该关联关系。该关联关系中，第一定时器对应的终端的搜网方式为历史频点搜网，即表示终端搜网时只在历史频点信息上搜网；第二定时器对应的终端的搜网方式为全频段搜网，即终端是在全频段范围内的频点信息上进行搜网。
为了更好的理解本发明实施例的技术方案，此处以一个简单的例子来进行说明：
假设终端设定第一定时器的时长为2s，终端执行历史频点搜网的时间为2s，第二定时器时长为10s，终端执行全频段搜网的时间为10s，则当终端从无网络环境移动至网络覆盖环境的过程中，终端启动第一定时器和第二定时 器(假设两个定时器在0s启动，则两个定时器从0s开始计时)。当时间到达2s时，确定第一定时器超时，则终端执行历史频点搜网，当第4s时，终端的历史频点搜网结束，假设终端此次并未在历史频点上搜网成功；对于第一定时器来说，时间从第2s到达第4s，故在第4s时第一定时器再次启动，当时间到达第6s时，确定第一定时器超时(第二定时器截止第6s还未超时)，则终端继续在历史频点上搜网，当第8s时，终端的历史频点搜网结束，假设终端此次在历史频点上搜网也未成功；对于第一定时器来说，时间从第6s到达第8s，故在第8s时第一定时器再次启动，当时间到达第10s时，确定第一定时器超时(此时第二定时器也超时，但终端此时可以选择先进行历史频点搜网)则终端继续在历史频点上搜网，假设此次搜网成功，则终端通过历史频点驻留在网络上，无需再进行全频段搜网；假设此次搜网不成功，则终端在第12s时再进行全频段搜网。由该例子可知，由于第一定时器的时长和第二定时器的时长不等，且第一定时器的时长小于第二定时器的时长，使得终端每隔2s执行一次历史频点搜网，每隔10s执行一次全频段搜网，故使得终端执行历史频点搜网的搜网频率高于全频段搜网的搜网频率，由于历史频点搜网时间短且更容易搜索到网络，因此本发明实施例使得历史频点进行频率更高的搜网，全频段搜网进行频率较低的搜网，从而使得终端更容易搜索到网络，并且执行全频段搜网的频率低，降低了终端的功耗并加快网络恢复的速度。
现有技术中，终端一旦掉网后，其就会启动历史频点搜网，当终端从无网络覆盖区移动至网络覆盖区的过程中，假设终端进行历史频点搜网时，其仍然处于无网络覆盖区(或信号盲区)，则手机在历史频点搜索不到网络后，就会自动跳至全频段搜网，待手机移动至网络覆盖区(或信号正常区)时，则当前进行的就是全频段搜网，则此时就有可能跳过历史频点或可用频点，即现有技术中终端执行历史频点搜网的频率和执行全频段搜网的频率相同，导致终端无法有效的搜索到可用频点，且搜网时间长，终端的功耗过大；但是，本发明实施例采用的是分层搜网的机制，终端根据超时定时器的类型确定终端按照哪一种搜网方式进行搜网(即根据超时定时器的类型确定终端执行哪一种搜网流程)，并通过设置时长不等的定时器使得终端执行历史频点搜网的频率高于执行全频段搜网的频率，从而使得终端可以快速的搜索到可 用频点；并且，由于终端执行全频段搜网的频率低，故降低了终端的功耗并加快网络恢复的速度。
本发明实施例提供的终端的搜网方法，终端通过预设时长不等的定时器，并在终端所启动的定时器超时时，根据所确定的超时定时器的类型和关联关系触发终端按照相应的搜网方式进行搜网。本发明实施例提供的方法采用分层搜网的机制，终端根据超时定时器的类型确定按照哪一种搜网方式进行搜网，并通过设置时长不等的定时器使得终端执行历史频点搜网的频率高于执行全频段搜网的频率，从而使得终端可以快速的搜索到可用频点；并且，由于终端执行全频段搜网的频率低，故降低了终端的功耗并加快网络恢复的速度。
为了解决多个定时器同时超时的问题，在图1所示实施例的基础上，作为本发明实施例的一种可能的实施方式，本实施例涉及的终端建立关联关系的具体过程。即上述S101之前，所述方法还包括：根据所述终端预设的历史频点和全频段之间的优先级信息，建立所述关联关系；其中，所述优先级信息包括：所述历史频点的优先级高于所述全频段的优先级。从而当遇到多个定时器超时的问题时，可以根据关联关系中的优先级信息，确定优先选择的搜网方式。
具体的，终端在建立关联关系时，可以结合终端所支持的频点信息的优先级信息，建立所述关联关系。具体的，终端可以将优先级高的频点信息设置为搜索频率高的频点信息，并将优先级低的频点信息设置为搜索频率低的频点信息。在本实施例中，由于第一定时器的时长小于第二定时器的时长，所以历史频点搜网的频率高于全频段搜网的频率，又由于历史频点的优先级高于全频段的优先级，所以进一步的增加了历史频点搜网的频率，减少了全频段搜网的频率，有利于降低功耗。
在图1所示实施例的基础上，作为本发明实施例的另一种可能的实施方式，本实施例涉及的终端建立关联关系的另一具体过程。进一步地，上述定时器集合还可以包括第三定时器，该第三定时器的时长大于第一定时器的时长且小于所述第二定时器的时长；上述优先级信息还包括：所述终端支持的第一频段的优先级低于所述历史频点的优先级，所述第一频段的优先级高于所述全频段的优先级，该第一频段为已注册的公共陆地移动网络(Registered  Public Land Mobile Network，以下简称RPLMN)运营商支持的频段信息。则在上述S101之前，所述方法还可以包括：根据所述终端预设的所述历史频点、所述第一频段和所述全频段之间的优先级信息，建立所述关联关系；所述关联关系中所述第三定时器对应的所述终端的搜网方式为第一频段搜网。
具体的，终端可以在定时器集合中加入第三定时器，并将第三定时器的时长设置为终端执行第一频段搜网的时长。该第一频段可以由终端预设在存储器中或者通过云端服务器进行空口(Over The Air，简称OTA)更新获得。本实施例中，第一频段的设置，使得终端在第二定时器未超时，并且终端在历史频点上始终无法搜到可用频点的场景下，可以进行第一频段搜网，进而使得终端可以快速搜索到可用频点。
本发明实施例提供的方法，通过将第三定时器的时长设置为终端执行第一频段搜网的频率，使得终端在第二定时器未超时，并且终端在历史频点上始终无法搜到可用频点的场景下，可以进行第一频段搜网，进而使得终端可以快速搜索到可用频点，提高了终端搜网的效率。
图2为本发明实施例提供的终端的搜网方法另一流程示意图。在上述实施例的基础上，本实施例涉及的是当定时器集合包括第一定时器、第二定时器和第三定时器时，终端在所启动的定时器超时时进行搜网的具体过程；当然，当定时器集合仅包括第一定时器和第二定时器时，也可以参照下述实施例的执行过程，其具体执行过程类似。进一步地，上述S102具体包括：
S201：分别判断定时器集合中的定时器是否超时。
具体的，当终端处于无网络覆盖区时，终端处于掉网状态，若终端从无网络覆盖区移动至网络覆盖区时，终端在预设的时间内会启动定时器，并判断定时器是否超时，从而确定出超时定时器的类型为第一定时器或第二定时器或第三定时器。可选的，终端可以同时启动第一定时器、第二定时器和第三定时器，并且监控这三个定时器是否超时。
S202：当任意定时器超时时，根据所述关联关系触发所述终端根据超时定时器对应的搜网方式进行搜网。
具体的，当终端判断上述三个定时器中的第一定时器超时时，终端根据所述关联关系执行与所述第一定时器对应的历史频点搜网；当终端判断第二定时器超时时，终端根据所述关联关系执行与所述第三定时器对应的第一频 段搜网；当终端判断第二定时器超时时，终端根据所述关联关系执行与所述第二定时器对应的全频段搜网。需要说明的是，若在终端根据上述定时器集合中的任一定时器对应的搜网方式进行搜网时，上述定时器集合中的其他定时器已超时，则终端会将其他定时器挂载运行(即不触发执行所述其他定时器对应的搜网流程)，并在终端执行当前搜网流程结束时刻，终端才会根据上述关联关系和终端预设的优先级信息执行与所述其他定时器对应的搜网流程。
需要说明的是，这里所说的其他定时器，可以为一个定时器，也可以为两个定时器。若在终端根据上述定时器集合中的任一定时器对应的搜网方式进行搜网时，定时器集合中的其他两个定时器均超时，则当终端执行完当前搜网流程时，终端会根据关联关系和这两个定时器对应的搜网方式中的频率信息的优先级确定终端应该按照哪一个定时器对应的搜网方式进行搜网。
为了更好了理解本发明实施例的技术方案，此处举一个简单的例子来说明，该例子结合图3所示的时间轴与搜网流程对应关系图来具体介绍：
假设终端设定第一定时器(T1)的时长为2s，终端执行历史频点搜网的时间为2s，第三定时器(T3)时长为10s，终端执行第一频段搜网的时间为10s，第二定时器(T2)时长为1min，终端执行全频段搜网的时间为1min。
当终端从无网络环境移动至网络覆盖环境的过程中，终端启动第一定时器、第二定时器和第三定时器(假设三个定时器均在0s启动，则三个定时器从0s开始计时)。当时间到达2s时，确定第一定时器超时，则终端执行历史频点搜网，当第4s时，终端的历史频点搜网结束，假设终端此次并未在历史频点上搜网成功；对于第一定时器来说，时间从第2s到达第4s，故在第4s时第一定时器再次启动，当时间到达第6s时，确定第一定时器超时(第二定时器和第三定时器截止第6s还未超时)，则终端继续在历史频点上搜网，当第8s时，终端的历史频点搜网结束，假设终端此次在历史频点上搜网也未成功；对于第一定时器来说，时间从第6s到达第8s，故在第8s时第一定时器再次启动，当时间到达第10s时，确定第一定时器超时(此时第三定时器在第10s时也确定为超时，但终端此时根据历史频点和第一频段的优先级确定优先进行历史频点搜网，将第三定时器挂载运行)，则终端继续在历史频点上搜网，当第12s时，终端的历史频点搜网结束(在第12s时，即在历史 频点搜网结束时刻，第一定时器再次启动)；假设终端此次在历史频点上搜网仍未成功，则由于之前第三定时器已超时，因此终端在第12s至第22s之间执行第一频段搜网(第一定时器在第14s时已超时，但由于当前终端进行的是第一频段搜网，则终端将第一定时器挂载运行，直至第一频段搜网结束时刻触发终端执行历史频点搜网)；若假设终端在第一频段上搜网仍未成功，则在第22s时第三定时器再次启动，且从第22s至第24s的时间内终端执行历史频点搜网；若假设在历史频点上搜网仍未成功，则终端在第24s时再次启动第一定时器，当时间到达26s时，确定第一定时器超时，则终端在第26s至第28s时间内执行历史频点搜网；若假设在历史频点上搜网仍未成功，则终端在第28s时再次启动第一定时器，当时间到达30s时，确定第一定时器超时，则终端在第30s至第32s时间内执行历史频点搜网；若假设在历史频点上搜网仍未成功，则在第32s时，第一定时器再次启动，并且由于前述的第三定时器在第22s启动，因此在第32s时确定第三定时器已超时，因此在第32s至第42s时间内终端执行第一频段搜网(第一定时器在第34s时已经超时，由于终端当前正在进行第一频段搜网，则终端此时将第一定时器挂载运行，直至第一频段搜网结束)；若假设在第一频段搜网仍未成功，则终端在第42s至第44s时间内执行历史频点搜网，并且在第42s时再次启动第三定时器(即在第一频段搜网结束时刻再次启动第三定时器)；若假设在历史频点上搜网仍未成功，则终端在第44s再次启动第一定时器，当时间到达46s时，确定第一定时器超时，则终端在第46s至第48s时间内执行历史频点搜网；若假设在历史频点上搜网仍未成功，则在第48s时，第一定时器再次启动，当时间到达50s时，确定第一定时器超时，则终端在第50s至第52s时间内执行历史频点搜网；若假设在历史频点上搜网仍未成功，则终端在第52s再次启动第一定时器，并且由于前述的第三定时器在第42s启动，因此在第52s时第三定时器已超时，因此在第52s至第62s时间内终端执行第一频段搜网(第一定时器在第54s时已经超时，由于终端当前正在进行第一频段搜网，则终端此时将第一定时器挂载运行，直至第一频段搜网结束，并且在第60s时确定第二定时器已超时，由于终端当前正在进行第一频段搜网，则终端此时也将第二定时器挂载运行，直至第一频段搜网结束)。若假设第一频段搜网仍未成功，则在第62s时，终端根据历史频点和全频段的优先级信息 确定先进行历史频点搜网，然后再进行全频段搜网，以此类推，直至终端搜网成功为止。
由该例子可知，由于第一定时器的时长、第二定时器和第三定时器的时长不等，且第一定时器的时长小于第三定时器的时长，第三定时器的时长小于第二定时器的时长，使得终端每隔2s执行一次历史频点搜网，每隔10s执行一次第一频段搜网，每隔1min执行一次全频段搜网，故使得终端执行历史频点搜网的频率高于执行第一频段搜网的频率，并且使得终端执行第一频段搜网的频率高于执行全频段搜网的频率。由于历史频点搜网时间短且更容易搜索到网络，因此本发明实施例使得历史频点进行频率更高的搜网，第一频段搜网进行频率次低的搜网，全频段搜网进行频率最低的搜网，从而使得终端更容易搜索到网络；并且，由于终端执行全频段搜网的频率低，降低了终端的功耗并加快网络恢复的速度。
在本发明实施例提供的终端的搜网方法中，终端启动定时器集合；所述定时器集合包括第一定时器、第二定时器、第三定时器，其中第一定时器的时长小于第二定时器的时长，第二定时器的时长小于第三定时器的时长。当所述定时器集合中至少一个定时器超时时，确定所述超时定时器的类型；根据所述超时定时器的类型，确定所述终端搜网的方式，具体的，当超时定时器的类型为第一定时器时，确定所述终端搜网的方式为历史频点搜网；当超时定时器的类型为第二定时器时，确定所述终端搜网的方式为第一频段搜网；当超时定时器的类型为第三定时器时，确定所述终端搜网的方式为全频段搜网。可选的，当多个超时器同时超时时，可以根据不同搜网方式的优先级，确定搜网方式的顺序。例如，预先设置历史频点的优先级大于第一频段，第一频段的优先级大于全频段，当第一定时器和第二定时器同时超时时，优先选择历史频点搜网的方式。
本发明实施例提供的终端的搜网方法，终端通过预设时长不等的定时器，并在终端所启动的定时器超时时，根据所确定的超时定时器的类型和关联关系触发终端按照相应的搜网方式进行搜网。本发明实施例提供的方法采用分层搜网的机制，终端根据超时定时器的类型确定按照哪一种搜网方式进行搜网，并通过设置时长不等的定时器使得终端执行历史频点搜网的频率高于执行第一频段搜网的频率，并且使得终端执行第一频段搜网的频率高于执行全 频段搜网的频率。由于历史频点搜网时间短且更容易搜索到网络，因此本发明实施例使得历史频点进行频率更高的搜网，第一频段搜网进行频率次低的搜网，全频段搜网进行频率最低的搜网，从而使得终端更容易搜索到网络，并且由于终端执行全频段搜网的频率低，降低了终端的功耗并加快网络恢复的速度。
