Description

一种电子设备及其搜索移动通信网络的方法 技术领域
本发明涉及通信技术领域，尤其涉及一种电子设备及其搜索移动通信网络的方法。
背景技术
目前越来越多用户希望同一电子设备可以在不同国家、不同技术标准的移动通信网络之间使用，而不需要根据不同网络更换不同的电子设备，这就要求同一电子设备可以同时支持多种网络制式以及多个网络频段，满足该要求的电子设备即我们通常所说的“全网通”设备。
但是，现有技术中，电子设备支持的网络制式和网络频段越多，其搜索到可接入的移动通信网络的时间就越长，其原因是：虽然电子设备支持多种网络制式以及多个网络频段，但是在具体使用时，电子设备依据其安装使用的用户身份识别卡，最终只能在一种网络制式的一个频段上驻留，而在现有的技术方案中，电子设备在搜索移动通信网络时，是对该电子设备支持的所有网络制式的所有频段依次进行搜索，每在一个网络制式的某一频段上搜索到移动通信网络时，均使用用户身份识别卡的相关信息进行网络鉴权，若鉴权成功则接入该移动通信网络，若鉴权失败，则继续扫描下一个频段，这样，该电子设备支持的网络制式和频段越多，该电子设备在进行网络搜索时，其需要扫描的网络制式和网络频段就越多，耗费的时间就越长，效率低下。
发明内容

移动通信网络中的电子设备为了能正常的接入访问移动网络，通常都需要安装用户身份识别卡，以便电子设备可以利用用户身份信息接入相关移动网络。常见的用户身份识别卡可以包括SIM(英文全称：Subscriber Identity Module，中文：客户识别模块)卡、或USIM(英文全称：Universal Subscriber Identity Module，中文：全球客户识别模块)卡、或UIM(英文全称：User Identity Module，中文：用户识别模块)卡等由运营商提供的卡。该用户身份识别卡还可以包括eSIM(英文：Embedded SIM，中文：嵌入式SIM)卡， 所述eSIM卡是将传统SIM卡直接嵌入到设备芯片上，而不是作为独立的可移除零部件加入电子设备中。
值得说明的是，该电子设备能够接入访问的移动通信网络的网络制式以及该移动通信网络的频段，与该用户身份识别卡当前所属的运营商以及该电子设备当前所处的地区相关。其中，对于SIM，USIM或者UIM等由运营商自身发行的用户身份识别卡来说，该用户身份识别卡当前所属的运营商即为发行该用户身份识别卡的运营商。由于eSIM卡支持用户根据自身需求选择运营商，因此，当该用户身份识别卡为eSIM卡时，该用户身份识别卡当前所属运营商为用户设置选定的运营商。
举例来讲，当该用户身份识别卡当前所属运营商为中国电信时，其在中国支持的网络制式有：LTE(英文全称：Long Term Evolution，中文：长期演进)和CDMA(英文全称：Code Division Multiple Access，中文：码分多址)，在香港支持的网络制式有：LTE、WCDMA(英文全称：Wideband Code Division Multiple Access，中文：宽带码分多址)、GSM(英文全称：Global System for Mobile communications，中文：全球移动通信系统)，在美国支持的网络制式有LTE、WCDMA和GSM。
当该用户身份识别卡当前所属运营商为中国移动时，其在中国支持的网络制式有：LTE、TD-SCDMA(英文全称：Time Division-Synchronous Code Division Multiple Access，中文：时分同步码分多址)和GSM，在美国支持的网络制式有：LTE、WCDMA和GSM。
对于同一网络制式，该网络制式在不同地区的频段也可能不同，例如，运营商为中国移动的用户身份识别卡，在中国使用的是TDD(英文全称：Time Division Duplexing，中文：时分双工)的LTE网络，但是在美国使用的是FDD(英文全称：Frequency Division Duplexing，中文：频分双工)的LTE网络。
该识别码可以为该用户身份识别卡的IMSI(英文全称：International Mobile Subscriber Identification，中文：国际移动用户识别)码，还可以是ICCID (英文全称：Integrate Circuit Card Identity，中文：集成电路卡识别)码。
S102、该电子设备根据该识别码在预置网络信息表中确定至少一项网络信息。
例如，该预置网络信息表包括M项网络信息，M为大于或等于1的正整数，所述至少一项网络信息可以是N项网络信息，N为小于或等于M的正整数。
该预置网络信息表可以是生产该电子设备的厂商预先设置在该电子设备中的，对于全网通设备，该预置网络信息表包括全部的网络制式和全频段，对于支持移动和联通双网的电子设备，该预置网络信息表包括移动和联通提供的网络制式和频段。
在本发明实施例的一种可能的实现方式中，该识别码包括该用户身份识别卡当前所属运营商的标识，则步骤S102具体包括：该电子设备根据该运营商的标识确定该用户身份识别卡的运营商信息，在该预置网络信息表中确定包括该运营商支持的网络制式的至少一项网络信息，其中，运营商支持的网络制式包括该运营商提供的网络制式和与该运营商有漫游协议的网络制式。
其中，IMSI码包括MCC(英文全称：Mobile Country Code，中文：移动国家码)以及MNC(英文全称：Mobile Network Code，中文：移动网号)，按照现有的规定，不同的移动国家代表不同的国家，例如，移动国家码460代表中国，移动国家码450代表韩国，不同的移动网号代表不同的运营商，例如，移动网号00代表中国移动，移动网号01中国联通。因此，该识别码为IMSI码时，该运营商的标识可以为MCC和MNC。
ICCID码包括国家编号以及运营商编号。例如，国家编号86代表中国，运营商编号00代表中国移动。因此，该识别码为IMSI码时，该运营商标识可以为营运商编号。
上述只是举例说明，该电子设备根据该用户身份识别卡的IMSI码或者ICCID码均可以确定该用户身份识别卡当前所属的运营商。本领域普通技术人员应该知悉，该识别码还可以是用户身份识别卡携带的能够表明该用户身 份识别卡当前所属运营商的其他信息，本发明对此不做限定。
示例地，若该电子设备是支持中国移动、中国联通以及中国电信的电子设备，且该预置网络信息表如下表1所示：
表1
Figure PCTCN2016078111-appb-000001
在此种情况下，若该用户身份识别卡的移动网号表明该用户身份识别卡当前所属运营商是中国电信，则该电子设备可以在上述包括M＝11项网络信息的表1中确定中国电信对应的包括LTE，WCDMA，GSM和CDMA的N＝4项网络信息为用于网络搜索的网络信息。
若该用户身份识别卡的移动网号表明该用户身份识别卡当前所属运营商是中国联通，则该电子设备在上述包括M＝11项网络信息的表1中确定中国联通对应的包括LTE，WCDMA和GSM的N＝3项三项网络信息为用于网络搜索的网络信息。
若该用户身份识别卡的移动网号表明该用户身份识别卡当前所属运营商是中国移动，则该电子设备在上述包括M＝11项网络信息的表1中确定中国移动对应的包括LTE，WCDMA，TD-SCDMA和GSM的N＝4项网络信息为 用于网络搜索的网络信息。
上述只是举例说明，表1中直接包括运营商标识、网络制式、频段三者的对应关系，这样，电子设备在获取到用户身份识别卡的运营商标识后，直接查询预置网络信息表即可获得该运营商对应的至少一项网络信息，即该运营商支持的网络制式以及所述网络制式对应的频段。可选地，该电子设备也可以建立并维护一张运营商标识与网络制式的对应关系表，以及一张包括网络制式与频段的对应关系的预置网络信息表，这样，该电子设备在获取到用户身份识别卡的运营商标识后，先从运营商标识与网络制式的对应关系表中确定该运营商支持的至少一项网络制式，再根据该至少一项网络制式查询预置网络信息表获得每项网络制式对应的频段，例如，该电子设备在确定发行该用户身份识别卡的运营商为中国电信时，可以从运营商标识与网络制式的对应关系表中确定中国电信支持LTE、WCDMA、GSM和CDMA四项网络制式，再从包括网络制式与频段的对应关系的预置网络信息表中获取该四项网络制式分别对应的频段，以此得到包括网络制式以及频段的四项网络信息。本发明对此不做限定。
在上述可能的实现方式中，电子设备支持多个网络制式的移动通信网络，但是，该电子设备在搜索网络时，无需对每个网络制式的频段进行扫描，而是扫描用户身份识别卡当前所属运营商支持的网络制式的频段，缩小了搜索范围，从而减少了搜索时间，提高了网络搜索的效率。
在本发明实施例的另一种可能的实现方式中，该预置网络信息表包括运营商、地区标识与网络信息的对应关系，在此种情况下，该电子设备还可以获取当前所处地区的地区标识，并在预置网络信息表中确定对应该地区标识的网络信息，则上述步骤S102具体包括：该电子设备根据该运营商标识在对应该地区标识的网络信息中确定包括该运营商支持的网络制式的至少一项网络信息。
示例地，该电子设备可以通过网络下发的网络信息来获得电子设备当前所处地区的地区标识，也可以通过GPS(英文全称：Global Positioning System， 中文：全球定位系统)或者WIFI定位技术来获得电子设备当前所处地区的地区标识。
示例地，该电子设备包括的预置网络信息表如表2所示，表2包含了中国电信运营商在不同国家所支持的多种网络制式：中国支持的LTE和CDMA，美国支持的LTE、WCDMA和GSM，以及中国移动运营商在不同国家支持的网络制式：中国支持的LTE、TDSCDMA和GSM，美国支持的LTE、WCDMA和GSM。在不同国家，可能支持相同的网络制式，但是支持不同的频段。
表2
Figure PCTCN2016078111-appb-000002
在此种情况下，若该用户身份识别卡当前所述运营商为中国移动，则该电子设备可以在上述M＝11的预置网络信息表中确定包括LTE(中国)，TD-SCDMA(中国)，GSM(中国)，LTE(美国)、WCDMA(美国)和GSM(美国)的6项网络信息。
进一步地，若该电子设备获得的地区标识表明该电子设备当前所处地区为中国，则该电子设备可在该6项网络信息中确定包括LTE(中国)，TD-SCDMA(中国)，GSM(中国)的N＝3项网络信息为用于网络搜索的网 络信息。
上述只是举例说明，在具体实施时，该电子设备也可以首先根据运营商标识从预置网络信息表中确定包括该运营商支持的网络制式的网络信息，再从包括该运营商支持的网络制式的网络信息中确定对应所述地区标识的至少一项网络信息，本发明对步骤的执行顺序不做限定，并且，参照上述对表1的描述，该电子设备也可以通过建立多张对应关系表记录运营商标识，地区标识，网络制式，频段之间的对应关系，本发明对此不做限定。
在上述可能的实现方式中，电子设备支持多个地区的多个运营商提供的多种网络制式的移动通信网络，该电子设备在搜索网络时，可以只扫描该用户身份识别卡当前所属的运营商在该电子设备当前所处地区所支持的网络制式的频段，无需对该电子设备支持的所有地区的所有运营商提供的网络制式的频段进行扫描，缩小了搜索范围，从而减少了搜索时间，提高了网络搜索的效率。
S103、该电子设备根据该至少一项网络信息中的频段搜索目标移动通信网络。
可选地，该预置网络信息表中包括每项网络信息的优先级，这样，该电子设备可以根据该至少一项网络信息的优先级依次根据每项网络信息中的频段进行网络搜索。
进一步地，该电子设备在搜索到可接入的移动通信网络，即所述目标移动通信网络后，经过网络鉴权，接入该目标移动通信网络。
可选地，该电子设备在接入该目标通信网络后，还可以保存该至少一项网络信息作为搜网列表，这样，该电子设备在下一次搜网移动通信网络时，可以直接根据该搜网列表进行搜索，而无需再从预置网络信息表中进行选择，提高了网络搜索效率。
可选地，该电子设备在接入该目标通信网络后，可以将预置网络信息表中的该目标移动通信网络的网络信息的优先级设置为最高，这样，若该电子设备所处地区以及安装的用户身份识别卡未发生变化，则该电子设备在下一 次进行网络搜索时，可以最快速的搜索到并接入该目标移动通信网络。在该电子设备保存了该至少一项网络信息作为搜网列表的情况下，该电子设备也可以将该搜网列表中的该目标移动通信网络的网络信息的优先级设置为最高。
在具体实施过程中，该电子设备保存包括该至少一项网络信息的搜网列表后，在下一次进行网络搜索时，可以先判断用户身份识别卡和电子设备所处地区是否发生变化，若两者均为发生变化，则该电子设备直接使用搜网列表进行网络搜索；在用户身份识别卡未发生更换且该电子设备无法获取到当前所在的地区标识时，也可以直接使用搜网列表进行网络搜索，若该电子设备采用搜网列表在预设时长内未搜索到网络，则可以再利用预置网络信息表中的每项网络信息进行网络搜索。若该电子设备在下一次进行网络搜索时，确定用户身份识别卡发生更换或者所处地区发生变化，则该电子设备可直接重新从预置网络信息表中选择网络信息进行网络搜索。
可选地，该电子设备在接入该目标通信网络后，还可以从网络侧获取到该目标移动通信网络的临区信息，并将该临区信息添加到该预置网络信息表中。
其中，该临区信息可以包括异频的网络信息，还可以包括异系统的网络信息，异频的网络信息是指与该目标移动通信网络的网络制式相同且频段不同的网络信息，异系统的网络信息是指与该目标移动通信网络的运营商相同且网络制式不同的网络信息。
值的说明的是，由于技术的更新，运营商支持的网络制式以及网络制式占用的频段不是一成不变的，因此，电子设备的预置网络信息表中记录的网络信息可能不完善，该电子设备在获取到该目标移动通信网络的临区信息后，可以先确定该预置网络信息表中不存在与该临区信息相同的网络信息，再将该临区信息添加到该预置网络信息表中。具体地，对于异频的临区信息，该电子设备可以只将该临区信息中的频段添加到该目标移动通信网络的网络制式对应的频段中；对于异系统的临区信息，该电子设备可以将该临区信息作 为一项新的网络信息添加到该预置网络信息表中，从而使得电子设备的预置网络信息表更加完善准确，并且，临区信息有利于电子设备进行网络重选。
在本发明实施例的一种可能的实现方式中，步骤S103还包括：若该电子设备根据该至少一项网络信息中的频段在预定时长内未搜索到该目标移动通信网络，则该电子设备在全频段范围内进行网络搜索。
具体地，该电子设备可以在开始进行搜网时，就启动OOS(英文全称：Out Of Service，中文：没有服务)定时器，如果在OOS定时器超时之前，电子设备搜索到了可接入的移动通信网络，就停止OOS定时器，如果OOS定时器超时，电子设备还没有搜索到可接入的移动通信网络，则在全频段范围内搜网。
在具体实施时，OOS定时器的时长可以通过至少一个网络信息中的网络制式、频段和频点来确定，例如，该至少一个网络信息中包括的网络制式、频段和频点越多，该OOS定时器的时间则可以设置越长，反之，该OOS定时器的时间就设置为越短。
值得说明的是，由于电子设备的预置网络信息表存在不完善的可能，因此导致该电子设备根据该至少一项网络信息可能无法搜索到可接入的移动通信网络，在上述可能的实现方式中，该电子设备根据该至少一项网络信息在预定时长内未搜索到可接入的移动通信网络时，可以在全频段范围内搜索网络，确保了电子设备尽最大可能去搜索移动通信网络。
进一步地，该电子设备在全频段范围内搜索到该目标移动通信网络后，获取该目标移动通信网络的网络信息和/或该目标移动通信网络的临区信息，并将该目标移动通信网络的网络信息和/或该目标移动通信网络的临区信息添加到该预置网络信息表中。
这样，该电子设备将在全频段范围内搜索到的目标移动通信网络的网络信息添加到预置网络信息表中，在下一次搜索网络时，该电子设备即可再次根据用户身份识别卡在更新后的预置网络信息表中选择网络信息进行搜网，避免了再次采用全频段搜网，提高了搜网效率。可选地，该电子设备还可以 将该目标移动通信网络的网络信息在预置网络信息表中的优先级设置为最高。
为了使本领域的技术人员更容易理解本发明实施例提供的一种电子设备搜索移动通信网络的方法，下面通过一个详细的实施例进行说明，如图2所示，包括：
S201、电子设备在预置网络信息表中确定包括用户身份识别卡当前所属的运营商支持的网络制式的网络信息。
该用户身份识别卡可以是插入该电子设备的实体卡，也可以是集成在该电子设备的设备芯片上的eSIM卡。步骤S201可参照上述对步骤S101以及S102的描述，此处不再赘述。
S202、该电子设备获取当前所处地区的地区标识。
S203、该电子设备在包括该运营商支持的网络制式的网络信息中确定对应该地区标识的至少一项网络信息。
在具体实施过程中，若该预置网络信息表中不存在符合上述条件的网络信息，该电子设备也可以直接执行步骤S211。

S210、该电子设备搜索下一个移动通信网络。
并且，该电子设备在搜索到下一个移动通信网络后，返回执行上述步骤S205。
S211、该电子设备在全频段范围内搜索移动通信网络。
S212、该电子设备在全频段范围内搜索并接入目标移动通信网络后，获取该目标移动通信网络的网络信息以及临区信息。
具体地，该电子设备在进行网络搜索时，是分制式进行搜索，并在不同制式下进行分频段搜索，如果电子设备搜索某一频段时，发现多个信号较强的频点，会去尝试驻留，若驻留失败，则搜索下一个频段，直到驻留成功，并接入当前搜索到的移动通信网络，当该电子设备接入该目标移动通信网络后，该电子设备就能够获取当前接入网络的制式和频点信息，并且，该电子设备根据不同的网络制式解析该目标移动通信网络下发的信息，还可以获取到该电子设备当前所处地区的地区标识。
例如，当该电子设备在插入中国移动卡进行LTE制式搜网时，发现了当前网络环境下可用的频点是38950，并且在频点38950该电子设备能成功的驻留和接入。这样，该电子设备利用3GPP TS 36.101表5.7.3-1中规定的频点和频段的对应关系可以确定频点38950对应的频段是B40。由此，可确定该目标移动通信网络的网络制式为LTE，频段为B40。同时，该电子设备还可以通过该标移动通信网络下发的系统信息块SystemInformationBlockType1获取plmn-Identity(英文全称：Public Land Mobile Network Identity，中文：中文公共陆地移动网络标识)中的MCC字段，得到地区标识。比如获取的MCC是460，则说明当前该电子设备所在的地区是中国。
LTE网络的临区消息可以通过SIB(英文全称：System Information Block，中文：系统信息块)消息获取。
其中，SIB5包含异频邻区，该电子设备通过interFreqCarrierFreqList中的 dl-CarrierFreq字段可以获取一个或者多个异频的临区信息，并且，利用3GPP TS 36.101表5.7.3-1中规定的频点和频段的对应关系可以确定对应的异频的频段信息，比如dl-CarrierFreq为37900，那么对应的异频的频段信息为B38。

SIB7包含GERAN(英文全称：GSM EDGE Radio Access Network，中文：增强型GSM无线接入网)邻区，该电子设备可以通过carrierFreqsInfoList中的bandIndicator字段获取当前异系统GERAN的频段信息。比如获取bandIndicator为dcs1800，那么对应的频段是B3。另外，GERAN邻区的网络制式为GSM。
SIB8包含CDMA邻区，该电子设备可以通过NeighCellListCDMA2000中bandClass字段获取一个或者多个获取当前异系统CDMA的频段信息。比如获取bandClass为bc0，那么对应的频段是BC0。
S213、该电子设备将该目标移动通信网络的网络信息以及临区信息添加到预置网络信息表中，并将该目标移动通信网络的网络信息的优先级设置为最高。
另外，图2所示步骤只是举例说明，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本发明并不受所描述的动作顺序的限制，其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作并不一定是本发明实施例所必须的。
采用上述方法，电子设备在搜索网络时，可以只扫描该用户身份识别卡当前所属的运营商在该电子设备当前所处地区所支持的网络制式的频段，无需对该电子设备支持的所有地区的所有运营商提供的网络制式的频段进行扫 描，缩小了搜索范围，从而减少了搜索时间，提高了网络搜索的效率，并且，该电子设备还可以在接入目标移动通信网络后，对预置网络信息表进行更新完善，有利于电子设备下一次进行网络搜索。
本发明实施例还提供一种电子设备30，该电子设备30安装有用户身份识别卡，用于实施上述方法实施例提供的一种搜索移动通信网络的方法，如图3所示，该电子设备30包括：

搜网单元33，用于根据该至少一项网络信息中的频段搜索目标移动通信网络。
采用上述电子设备，该电子设备在搜索移动通信网络时，只需对预置网络信息表中与用户身份识别卡的识别码相匹配的部分网络信息的频段进行搜索，无需对该电子设备支持的所有网络制式进行搜索，缩小了搜索范围，提高了搜索效率。
可选地，该识别码包括该用户身份识别卡当前所属运营商的标识，该确定单元32具体用于执行：根据该运营商的标识确定该运营商支持的网络制式；在该预置网络信息表中确定包括该运营商支持的网络制式的该至少一项网络信息。运营商支持的网络制式包括该运营商提供的网络制式以及与该运营商具有漫游协议的网络制式，可选地，该预置网络信息表可以包括运营商标识与网络信息的对应关系，这样，该电子设备在获取到该用户身份识别卡的运营商标识后，直接查询该预置网络信息表即可获得与该运营商标识对应的该至少一项网络信息。具体可参照方法实施例中表1对应的描述，此处不再赘述。其中，电子设备支持的运营商可能为多个，但是，电子设备使用的用户身份识别卡在接入网络时支持的运营商只有一个。上述电子设备在搜索移动通信网络时，可以根据该识别码获知该用户身份识别码当前所属运营商，进而该电子设备只需对该运营商支持的网络制式进行搜索，无需对该电子设备 支持的所有网络制式进行搜索，缩小了搜索范围，提高了搜索效率。
可选地，该预置网络信息表包括地区标识与网络信息的对应关系，该识别码包括该用户身份识别卡当前所属运营商的标识，该获取单元31还用于，获取该电子设备当前所处地区的地区标识；该确定单元32具体用于，在该预置网络信息表中确定对应该地区标识的网络信息，根据该运营商的标识在对应该地区标识的网络信息中确定该至少一项网络信息。运营商支持的网络制式与该运营商所处的地区相关，因此，在上述可能的实现方式中，该电子设备可以同时根据该运营商标识以及该电子设备当前所处地区的标识选择出该地区的该运营商支持的网络制式。可选地，该电子设备也可以先根据该运营商标识选择出包括该运营商支持的网络制式的网络信息，再根据该地区标识选择出该至少一项网络信息。可选地，该电子设备在根据该至少一项网络信息搜索到可接入的移动通信网络后，还可以保存该至少一向网络信息作为搜网列表，这样，该电子设备在下一次进行网络搜索时，可以直接根据该至少一项网络信息进行搜索，无需再次从该预置网络信息表中选择网络信息。具体可参照方法实施例中对表2的描述，此处不再赘述。
可选地，该识别码为该用户身份识别卡的国际移动用户识别码IMSI，该运营商标识包括移动网号MNC；或者，该识别码为该用户身份识别卡的集成电路卡识别码ICCID，该运营商标识包括运营商编号。
可选地，该用户身份识别卡为客户识别模块SIM卡，或者全球客户识别模块USIM卡，或者用户识别模块UIM卡，或者嵌入式eSIM卡。对于SIM，USIM或者UIM等由运营商自身发行的用户身份识别卡来说，该用户身份识别卡当前所属的运营商即为发行该用户身份识别卡的运营商。由于eSIM卡支持用户根据自身需求选择运营商，因此，当该用户身份识别卡为eSIM卡时，该用户身份识别卡当前所属运营商为用户设置选定的运营商。
可选地，该电子设备还包括通信单元34，用于在该搜网单元33根据该至少一项网络信息中的频段搜索到该目标移动通信网络后，获取该目标移动通信网络的临区信息；该电子设备还包括管理单元35，用于将该目标移动通信 网络的临区信息更新到该预置网络信息表中。
可选地，该搜网单元33还用于，根据该至少一项网络信息中的频段在预定时长内未搜索到该目标移动通信网络，在全频段范围内进行网络搜索；该通信单元34用于在该搜网单元搜索到该目标通信网络后，获取该目标移动通信网络的网络信息和/或该目标移动通信网络的临区信息；该管理单元35用于将该目标移动通信网络的网络信息和/或该目标移动通信网络的临区信息添加到该预置网络信息表中。该电子设备将搜索到的移动通信网络的网络信息添加到预置网络信息表中，避免该电子设备在下一次搜索网络时，仍然需要在全频段范围内搜索网络。该电子设备将该移动通信网络的临区信息更新该预置网络信息表，提高了电子设备网络重选的效率。
可选地，该搜网单元33具体用于，按照该至少一项网络信息的优先级依次根据每种网络制式对应的频段搜索该目标移动通信网络；该管理单元35还用于，调整该目标移动通信网络的网络信息在该预置网络信息表中的优先级。例如，将该目标移动通信网络的网络信息的优先级设置为最高，这样，在该电子设备未更换用户身份识别卡且未改变地区的情况下，该电子设备在下一次进行网络搜索时，可以最快速的搜索到该目标移动通信网络并进行接入，进一步提高了网络搜索的效率。
值得说明的是，以上对电子设备30的单元划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，并且，上述各功能单元的物理实现也可能有多种实现方式，例如，上述确定单元32具体可以是一中央处理器，也可以是特定集成电路(英文全称：Application Specific Integrated Circuit，简称：ASIC)。
