Abstract

Disclosed are a network access method and a mobile communications terminal. The method comprises: 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 the mobile communications terminal; if a PLMN matching the network identifier of the EPLMN is discovered by searching, then establishing a communications connection between the mobile communications terminal and the 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 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.

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

8. The mobile communication terminal of claim 7, 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:

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.

9. The mobile communication terminal of claim 6, wherein when the processor executes the program instructions to establish the 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, the processor executes the program instructions to perform following steps:

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;

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.

10. The mobile communication terminal of claim 9, wherein the processor executes the program instructions to perform a following step:

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

11. A non-transitory computer-readable storage medium, storing a computer program thereon, wherein the computer program is executed by a processor to implement a method for accessing to a network, the method 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.

12. The non-transitory computer-readable storage medium of claim 11, wherein the network identity comprises a network code.

13. The non-transitory computer-readable storage medium of claim 12, 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.

14. The non-transitory computer-readable storage medium of claim 11, 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.

15. The non-transitory computer-readable storage medium of claim 14, wherein the method further comprises:

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