Abstract
A network access method includes transmitting a request for acquiring shared network information to a shared server if a mobile communication terminal detects that a network identification of a PLMN of a visited place does not exist in a local memory of the mobile communication terminal; receiving the shared network information which the shared server transmits in response to the request, and acquiring the network identification of the PLMN of the visited place from the shared network information; 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.
Claims20
A network access method, comprising:
- transmitting a request for acquiring shared network information to a shared server 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 of the mobile communication terminal, wherein the network identification of the PLMN of the visited place is a network identification 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, and the shared network information comprises the network identification of the PLMN of the visited place which a second terminal pushes to the shared server;
- receiving the shared network information which the shared server transmits in response to the request, and acquiring the network identification of the PLMN of the visited place from the shared network information;
- 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.
A mobile communication terminal, comprising:
- a transmitting module configured to transmit a request for acquiring shared network information to a shared server if the 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 of the mobile communication terminal, wherein the network identification of the PLMN of the visited place is a network identification 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 is attached, and the shared network information comprises the network identification of the PLMN of the visited place which a second terminal pushes to the shared server;
- an acquiring module configured to receive the shared network information which the shared server transmits in response to the request, and acquiring the network identification of the PLMN of the visited place from the shared network information;
- an adding module configured to add 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
- a network access module configured to access a network according to the EPLMN list.
