    • The present invention relates to a method for optimizing a search of a Public Land Mobile Network (PLMN) by a mobile terminal having a nonvolatile memory and a Subscriber Identity Module (SIM) card. The method includes: searching for a PLMN based on priority information registered in the SIM; regarding the PLMN that has been found, determining whether the SIM card includes any priority information about at least one particular radio access technology associated with the PLMN; when priority information is included, selecting a cell of the PLMN; when priority information is not included, determining whether the nonvolatile memory includes any information about at least one particular radio access technology to be selected on a priority basis in a country of the PLMN; when priority information is included, selecting a cell of the PLMN for which the particular radio access technology has been developed; and when priority information is not included, selecting a cell where a radio access technology, which is set beforehand by default in the nonvolatile memory for all countries that are not listed in the nonvolatile memory, has been developed.
    • 本发明涉及一种通过具有非易失性存储器和用户身份模块(SIM)卡的移动终端优化公共陆地移动网络(PLMN)的搜索的方法。 该方法包括:基于SIM中登记的优先级信息,搜索PLMN; 关于已经找到的PLMN,确定SIM卡是否包括关于与PLMN相关联的至少一个特定无线电接入技术的任何优先级信息; 当包括优先级信息时,选择PLMN的小区; 当不包括优先级信息时,确定非易失性存储器是否包括关于在PLMN的国家中优先选择的至少一个特定无线电接入技术的任何信息; 当包括优先级信息时,选择已经开发了特定无线电接入技术的PLMN的小区; 并且当不包括优先级信息时,选择在非易失性存储器中未列出的所有国家的非易失性存储器中预先设置的无线接入技术已被开发的小区。
