Abstract
A network access method includes logging in to a shared server via a shared account, if a mobile communication terminal detects that a network identification of a public land mobile network (PLMN) of a visited place does not exist in a local memory; searching the shared network information in the shared server online via a network and acquiring the network identification of the PLMN of the visited place from the shared network information, after the shared server is logged in to; adding the network identification of the PLMN of the visited place to an EPLMN list by the mobile communication terminal; and accessing a network according to the EPLMN list.
Claims6
A network access method, comprising:
- logging in to a shared server via a shared account if a mobile communication terminal detects that a network identification of a public land mobile network (PLMN) of a visited place does not exist in a local memory, wherein shared network information is stored in the shared server, and the network identification of the PLMN of the visited place is a network identification of a PLMN of an operator of the visited place, which signs a roaming agreement with an operator of a home place to which a subscriber identity module attached to the mobile communication terminal belongs;
- searching the shared network information in the shared server online via a network and acquiring the network identification of the PLMN of the visited place from the shared network information, after the shared server is logged in to;
- adding the network identification of the PLMN of the visited place to an equivalent PLMN (EPLMN) list by the mobile communication terminal, wherein the EPLMN list comprises a network identification of a PLMN of the home place and the network identification of the PLMN of the visited place;
- and
- accessing a network according to the EPLMN list,
- wherein the accessing the network according to the EPLMN list comprises:
- searching the network in the visited place by the mobile communication terminal which is moved to the visited place;
- and
- establishing, if the PLMN of the visited place matching with the network identification in the EPLMN list is searched in the visited place, a communication connection between the mobile communication terminal and the matching PLMN of the visited place.
A mobile communication terminal, comprising:
- a login module configured to log in to a shared server via a shared account if it is detected that a network identification of a public land mobile network (PLMN) of a visited place does not exist in a local memory, wherein shared network information is stored in the shared server, and the network identification of the PLMN of the visited place is a network identification of a PLMN of an operator of the visited place, which signs a roaming agreement with an operator of a home place to which a subscriber identity module attached to the mobile communication terminal belongs;
- an online searching module configured to search the shared network information in the shared server online via a network and acquiring the network identification of the PLMN of the visited place from the shared network information, after the login module logs in to the shared server;
- an adding module configured to add the network identification of the PLMN of the visited place searched by the online searching module to an equivalent (EPLMN) list, wherein the EPLMN list comprises a network identification of a PLMN of the home place and the network identification of the PLMN of the visited place;
- and
- a network access module configured to access a network according to the EPLMN list,
- wherein the network access module comprises:
- a searching unit configured to search the network in the visited place;
- and
- a networking unit configured to establish, if the PLMN of the visited place matching with the network identification in the EPLMN list is searched in the visited place, a communication connection between the mobile communication terminal and the matching PLMN of the visited place.
