Abstract

Disclosed in the embodiments of the present invention are a network access method and a mobile communications terminal, comprising: first determining the current position of a mobile communications terminal; if the network identifier of the public land mobile network (PLMN) corresponding to said position has not been added to a pre-stored first equivalent public land mobile network (EPLMN) list, then scanning a Bluetooth low energy protocol broadcast channel; when a second EPLMN list published to said Bluetooth low energy protocol broadcast channel is detected by scanning, obtaining said second EPLMN list; if the network identifier of the PLMN corresponding to said position is added to said second EPLMN list, then lastly, accessing the network according to said second EPLMN list.

Claims

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

using a mobile communication terminal having a processor and a memory storing a plurality of program instructions executed by the processor to determine a location of a mobile communication terminal according to an iconic building that sits on the location;

using the processor to execute the plurality of program instructions to scan a Bluetooth low energy (BLE) protocol broadcast channel recorded in the mobile communication terminal if a network identity of a public land mobile network (PLMN) corresponding to the location is not included in a first equivalent public land mobile network (EPLMN) list stored in the memory;

using the processor to execute the plurality of program instructions to extract a second EPLMN list including a plurality of network identities of PLMNs stored in another mobile communication terminal over the BLE protocol broadcast channel, wherein the second EPLMN list is a shared EPLMN list in response to a share request broadcast by the mobile communication terminal;

using the processor to execute the plurality of program instructions to add the plurality of network identities of PLMNs included in the second EPLMN list to the first PLMN list; and

using the processor to execute the plurality of program instructions to detect whether the network identity of the PLMN corresponding to the location is added into the second EPLMN list, and access the network based on the second EPLMN list if the second EPLMN is added with the network identity of the PLMN corresponding to the location, wherein each of the first EPLMN list and the second EPLMN list comprises equivalent PLMNs deployed by different operators, and the equivalent PLMNs stored in the first EPLMN list and the plurality of network identities of PLMNs from the second EPLMN list have a same priority during network searching.

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

3. The method of claim 2, further comprising:

using the processor to execute the plurality of program instructions to broadcast the share request to share the second EPLMN list on the BLE protocol broadcast channel.

4. The method of claim 3, wherein the step of using the processor to execute the plurality of program instructions to extract the second EPLMN list including the plurality of network identities of PLMNs stored in another mobile communication terminal over the BLE protocol broadcast channel comprises:

using the processor to execute the plurality of program instructions to extract the second EPLMN list when the second EPLMN list released on the BLE protocol broadcast channel by another mobile communication terminal in response to the share request is detected.

5. The method of claim 1, further comprising:

when the accessing the network based on the second EPLMN list succeeds, using the processor to execute the plurality of program instructions to output a reminder message to remind the user of a time taken to access the network.

6. The method of claim 2, further comprising:

when the accessing the network based on the second EPLMN list succeeds, using the processor to execute the plurality of program instructions to output a reminder message to remind the user of a time taken to access the network.

7. A mobile communication terminal, comprising:

a processor; and

a memory connected with the processor, wherein the memory stores a plurality of program instructions executable by the processor, wherein execution of the instructions by the processor causes the processor to perform operations comprising;

determining a location of the mobile communication terminal according to an iconic building that sits on the location;

scanning a Bluetooth low energy (BLE) protocol broadcast channel recorded in the mobile communication terminal if a network identity of a public land mobile network (PLMN) corresponding to the location determined by the processor is not included in a first equivalent public land mobile network (EPLMN) list stored in the memory;

extracting a second EPLMN list including a plurality of network identities of PLMNs stored in another mobile communication terminal over the BLE protocol broadcast channel, and add the plurality of network identities of PLMNs included in the second EPLMN list to the first PLMN list, wherein the second EPLMN list is a shared EPLMN list in response to a share request broadcast by the mobile communication terminal;

detecting whether the network identity of the PLMN corresponding to the location is added into the second EPLMN list; and

accessing to the network based on the second EPLMN list if the second EPLMN is added with the network identity of the PLMN corresponding to the location, wherein each of the first EPLMN list and the second EPLMN list comprises equivalent PLMNs deployed by different operators, and the equivalent PLMNs stored in the first EPLMN list and the plurality of network identities of PLMNs from the second EPLMN list have a same priority during network searching.

8. The mobile communication terminal of claim 7, wherein the network identity includes network codes.

9. The mobile communication terminal of claim 8, the operations further comprising:

broadcasting the share request to share the second EPLMN list on the BLE protocol broadcast channel.

10. The mobile communication terminal of claim 9, wherein the extracting the second EPLMN list including the plurality of network identities of PLMNs stored in another mobile communication terminal over the BLE protocol broadcast channel comprises:

extracting the second EPLMN list when the second EPLMN released by another mobile communication terminal in response to the share to share the second EPLMN list on the BLE protocol broadcast channel is detected.

11. The mobile communication terminal of claim 7, the operations further comprising:

when the accessing to the network based on the second EPLMN list succeeds, outputting a reminder message to remind the user of a time taken to access the network.

12. The mobile communication terminal of claim 8, the operations further comprising:

when the accessing to the network based on the second EPLMN list succeeds, outputting a reminder message to remind the user of a time taken to access the network.
