1. A network accessing method, comprising:
- acquiring, by a mobile communication terminal, order information;
parsing, by the mobile communication terminal, the order information to acquire information of a visited place;
determining, by the mobile communication terminal, whether the public land mobile network (PLMN) network identifier of the visited place is stored in an equivalent home public land mobile network (EHPLMN) list;
acquiring, by the mobile communication terminal, the PLMN network identifier of the visited place when it is determined that the PLMN network identifier of the visited place is not stored in the EHPLMN list, and adding the PLMN network identifier of the visited place to the EHPLMN list;
acquiring, by the mobile communication terminal, current geographic position information of the mobile communication terminal;
determining, by the mobile communication terminal, whether the current geographic location information of the mobile communication terminal matches with the information of the visited place; and
performing, by the mobile communication terminal, network access according to the EHPLMN list when it is determined that the current geographic position information of the mobile communication terminal matches with the information of the visited place,wherein performing network access according to the EHPLMN list by the mobile communication terminal comprises;
searching network at the visited place by the mobile communication terminal that is moved to the visited place; and
when the PLMN of the visited place matching with a network identifier of the EHPLMN list is found at the visited place, establishing a communication connection between the mobile communication terminal and the matched PLMN of the visited place.

Abstract
A network access method and a mobile communication terminal are provided. The method includes the following steps: order information is acquired, the order information is parsed to acquire information of a visited place, a network identifier of a visited public land mobile network (VPLMN) is acquired when it is determined that the network identifier of the VPLMN is not stored in the EHPLMN list, and the network identifier of the VPLMN is added to the EHPLMN list. Network access is then performed according to the EHPLMN list.
