Abstract

A method for automatically selecting a network and a terminal thereof are provided by the present invention. Wherein, the method includes: prestoring a MCC and MNC list with priority; the terminal acquiring network parameter information; determining that the terminal is located in multiple networks according to the network parameter information; the terminal preferentially requesting to access one network from the multiple networks according to the MNC and MCC list; and the terminal refusing to access some networks according to the MNC and MCC list. With the present invention, the terminal can select the network to access according to the priority of the operator.

Claims

1. A method for automatically selecting a network, comprising the following steps:

prestoring a Mobile Country Code, MCC, and Mobile Network Code, MNC, list with priority;

a terminal acquiring network parameter information;

determining that the terminal is located in multiple networks according to the network parameter information;

the terminal preferentially requesting to access one network from the multiple networks according to the MNC and MCC list; and

the terminal refusing to access some networks according to the MNC and MCC list.

2. The method according to claim 1, wherein each of the preset networks has a priority, the multiple networks comprise multiple preset networks, and the step of the terminal preferentially requesting to access the preset networks from the multiple networks specifically comprises:

the terminal selecting the networks having network signal intensities larger than a threshold from the multiple preset networks; and

the terminal requesting to access the network with the highest priority from the networks having network signal intensities larger than the threshold.

3. The method according to claim 1, wherein the step of the terminal refusing to access some networks according to the MNC and MCC list specifically comprises:

if the network parameter information acquired by the terminal is a refusal network in the list, the terminal refusing to access even the network signal intensity is larger than the threshold.

4. The method according to claim 1, wherein the levels of the priority are set by the operator according to the cooperation relationships between it and operators of the preset networks.

5. The method according to claim 4, wherein the terminal is a dual-mode terminal, and the method further comprises:

if the dual-mode terminal preferentially requests to access the preset network which is a 2G network, it selects the 2G network and requests to access after network mode switching.

11. The method according to claim 2, wherein the step of the terminal refusing to access some networks according to the MNC and MCC list specifically comprises:

if the network parameter information acquired by the terminal is a refusal network in the list, the terminal refusing to access even the network signal intensity is larger than the threshold.

6. A terminal, comprising:

an acquiring module, configured to acquire network parameter information;

a network determining module, configured to determine that the terminal is located in multiple networks according to the network parameter information; and

a selecting module, configured to preferentially request to access a preset network from the multiple networks.

7. The terminal according to claim 6, wherein each of the preset networks has a priority, the multiple networks comprise multiple preset networks, and the selecting module further comprises:

a network selecting module, configured to select the networks having network signal intensities larger than a threshold from the multiple preset networks; and

a requesting access module, configured to request to access the network with the highest priority from the networks having network signal intensities larger than the threshold.

8. The terminal according to claim 6, wherein the terminal further comprises:

a storing module, configured to store the country code, the network code and the priority of each preset network.

9. The terminal according to claim 8, wherein the levels of the network priority stored by the storing module are set by the operator according to the cooperation relationships between it and operators of the preset networks.

10. The terminal according to claim 9, wherein the terminal is a dual-mode terminal, and the terminal further comprises:

a switching module, configured to, if the dual-mode terminal preferentially requests to access the preset network which is a 2G network, select the 2G network and request to access after network mode switching.

12. The terminal according to claim 7, wherein the terminal further comprises:

a storing module, configured to store the country code, the network code and the priority of each preset network.

13. The terminal according to claim 12, wherein the levels of the network priority stored by the storing module are set by the operator according to the cooperation relationships between it and operators of the preset networks.

14. The terminal according to claim 13, wherein the terminal is a dual-mode terminal, and the terminal further comprises:

a switching module, configured to, if the dual-mode terminal preferentially requests to access the preset network which is a 2G network, select the 2G network and request to access after network mode switching.
