Abstract

Disclosed in the embodiments of the present invention are a network access method and a mobile communications terminal, comprising: determining a network standard supported by a mobile communications terminal; adding to an equivalent public land mobile network (EPLMN) the network identifier of a public land mobile network (PLMN) of the determined network standard supported by said mobile communications terminal; if a PLMN matching the network identifier of said EPLMN is discovered by searching, then establishing a communications connection between said mobile communications terminal and said matching PLMN.

Claims

1. A method for accessing to a network, comprising:

determining a network standard supported by a mobile communication terminal;

adding a network identity of a public land mobile networks (PLMN) in compliance with the determined network standard supported by the mobile communication terminal to an equivalent public land mobile network (EPLMN) list; and

establishing a communication connection between the mobile communication terminal and a matching PLMN upon a condition that the matching PLMN is found to match the network identity in the EPLMN list.

2. The method of claim 1, wherein the network identity comprises a network code.

3. The method of claim 2, wherein a step of adding a network identity of a public land mobile networks (PLMN) in compliance with the determined network standard supported by the mobile communication terminal to an equivalent public land mobile network (EPLMN) list comprises:

detecting a type of user identification card supported by the mobile communication terminal based on the network standard supported by the mobile communication terminal;

determining the network identity of PLMN in compliance with the network standard supported by the mobile communication terminal based on the type of user identification card;

adding the network identity to the EPLMN list.

4. The method of claim 1, wherein a step of establishing a communication connection between the mobile communication terminal and a matching PLMN upon a condition that the matching PLMN is found to match the network identity in the EPLMN list, comprises:

scanning network identities of PLMNs broadcasted by a base station;

comparing the scanned network identities of the PLMNs with the network identity of PLMN in the EPLMN list; and

establishing, upon a condition that one of the scanned network identities matches the network identity of PLMN in the EPLMN list, the communication connection between the mobile communication terminal and the matching PLMN.

5. The method of claim 4, further comprising:

outputting a reminder message to remind the user of a time needed to connect to the network this time.

6. A mobile communication terminal, comprising:

a standard determining unit, configured to determine a network standard supported by the mobile communication terminal;

an adding unit, configured to add a network identity of a public land mobile networks (PLMN) in compliance with the determined network standard supported by the mobile communication terminal to an equivalent public land mobile network (EPLMN) list; and

an accessing unit, configured to achieve a communication connection between the mobile communication terminal and a matching PLMN upon a condition that the matching PLMN is found to match the network identity in the EPLMN list.

7. The mobile communication terminal of claim 6, wherein the network identity comprises network code.

8. The mobile communication terminal of claim 7, wherein the adding unit comprises:

a type standard determining unit, configured to determine a type of user identification card supported by the mobile communication terminal based on the network standard supported by the mobile communication terminal;

a network identity standard determining unit, configured to determine the network identity of the PLMN in compliance with the network standard supported by the mobile communication terminal based on the type of user identification card supported by the mobile communication terminal determined by the type standard determining unit; and

a network identity adding unit, configured to add the network identity determined by the network identity standard determining unit into the EPLMN list.

9. The mobile communication terminal of claim 6, wherein the accessing unit comprises:

a network identity extracting unit, configured to scan network identities of PLMNs broadcasted by a base station;

a matching unit, configured to compare the network identities of the PLMNs scanned by the network identity extracting unit with the network identity of the PLMN in the EPLMN list; and

a communication accessing unit, configured to establish, upon a condition that one of the scanned network identities matches the network identity of PLMN in the EPLMN list, the communication connection between the mobile communication terminal and the matching PLMN.

10. The mobile communication terminal of claim 9, wherein the outputting unit is further configured to output a reminder message to remind the user of a time needed to connect to the network this time.

11. A mobile communication terminal comprising a processor and a memory configured to store program instructions, wherein the processor executes the program instructions to determine a network standard supported by the mobile communication terminal;

the processor executes the program instructions to add a network identity of a public land mobile networks (PLMN) in compliance with the determined network standard supported by the mobile communication terminal to an equivalent public land mobile network (EPLMN) list;

the processor executes the program instructions to establish a communication connection between the mobile communication terminal and a matching PLMN upon a condition that the matching PLMN is found to match the network identity in the EPLMN list.

12. The mobile communication terminal of claim 11, wherein the network identity comprises a network code.

13. The mobile communication terminal of claim 12, wherein when the processor executes the program instructions to add a network identity of a public land mobile network (PLMN) in compliance with the determined network standard supported by the mobile communication terminal to an equivalent public land mobile network (EPLMN) list, the processor executes the program instructions to perform following steps:
