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.

Claims

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.

2. The method of claim 1, wherein acquiring the PLMN network identifier of the visited place by the mobile communication terminal comprises one of the following:

acquiring, by the mobile communication terminal, the PLMN network identifier of the visited place via a shared server; and

receiving, by the mobile communication terminal, the PLMN network identifier of the visited place entered by a user.

3. The method of claim 2, 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.

4. The method of claim 1, 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.

5. The method of claim 1, wherein the visited place and home are belonged to different countries or different districts.

6. A mobile communication terminal, comprising:

a first acquiring unit configured to acquire order information;

a parsing unit configured to parse the order information acquired by the first acquiring unit to acquire information of a visited place;

a determining unit configured to determine 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;

a second acquiring unit configured to acquire the PLMN network identifier of the visited place when the determining unit determines that the PLMN network identifier of the visited place is not stored in the EHPLMN list;

an adding unit configured to add the PLMN network identifier of the visited place acquired by the second acquiring unit to the EHPLMN list;

a third acquiring unit configured to acquire current geographic position information of the mobile communication terminal;

a detecting unit configured to determine whether the current geographic location information of the mobile communication terminal acquired by the third acquiring unit matches with the information of the visited place; and

a network accessing unit configured to perform network access according to the EHPLMN list when the detecting unit determines that the current geographic position information of the mobile communication terminal matches with the information of the visited place.

7. The mobile communication terminal of claim 6, wherein the second acquiring unit is configured to acquire the PLMN network identifier of the visited place via a shared server, or receive the PLMN network identifier of the visited place entered by a user.

8. The mobile communication terminal of claim 7, wherein the network accessing unit is configured to search 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, the network accessing unit is configured to establish a communication connection between the mobile communication terminal and the matched PLMN of the visited place.

9. The mobile communication terminal of claim 6, wherein the network accessing unit is configured to search 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, the network accessing unit is configured to establish a communication connection between the mobile communication terminal and the matched PLMN of the visited place.

10. The mobile communication terminal of claim 6, wherein the visited place and home are belonged to different countries or different districts.
