Abstract

The present disclosure generally relates to the technical field of communications, and discloses a method of using a base station signal to quickly set call forwarding and a mobile communication terminal. The method comprises the following steps of: A. carrying out setting of call forwarding, and saving a base station information of a wireless network where the call forwarding is set; and B. reading a call forwarding target phone number that is set, sending a call forwarding request to the wireless network, and after a confirmation is obtained from the wireless network, activating a check timer to complete the setting of call forwarding.

Claims

1. A method of using a base station signal to quickly set call forwarding, comprising the following steps of:

A. carrying out setting of call forwarding, and saving a base station information of a wireless network where the call forwarding is set; and

B. reading a call forwarding target phone number that is set, sending a call forwarding request to the wireless network, and after a confirmation is obtained from the wireless network, activating a check timer to complete the setting of call forwarding.

2. The method of using a base station signal to quickly set call forwarding of claim 1, further comprising the following steps of:

C. activating the check timer according to a timing, checking a location of the call forwarding, and reading a base station information of a current wireless network;

D. comparing the base station information of the current wireless network with the base station information of the wireless network where the call forwarding is set to determine a change in location; and

E. if a change in location is determined, then canceling the setting of call forwarding automatically.

3. The method of using a base station signal to quickly set call forwarding of claim 1, wherein the step A further comprises:

saving the base station information of the wireless network where the call forwarding is set into a non-volatile random access memory (NVRAM).

4. The method of using a base station signal to quickly set call forwarding of claim 2, wherein the base station information comprises an active cell identification (Active_CELL_ID), an active cell signal strength (Active_RXLev) and a neighbor cell identification (Neighbor_CELL_ID).

5. The method of using a base station signal to quickly set call forwarding of claim 4, wherein the step D comprises the following steps of:

D1. comparing the active cell identification and the neighbor cell identification in the base station information of the current wireless network with the active cell identification and the neighbor cell identification in the base station information of the wireless network where the call forwarding is set respectively;

D2. if at least one pair of the identifications is found to be identical to each other, then it means that the location has not changed and is still located in an original call forwarding area; and

D3. if neither pair of the identifications is found to be identical to each other, then it means that the location has changed and moved away from the original call forwarding area.

8. The method of using a base station signal to quickly set call forwarding of claim 4, wherein the number of the neighbor cells is 5.

9. The method of using a base station signal to quickly set call forwarding of claim 1, wherein the check timer is a software function.

6. A mobile communication terminal, comprising:

a call forwarding setting and saving module, being configured to carry out setting of call forwarding, and save a base station information of a wireless network where the call forwarding is set; and

a call forwarding confirming module, being configured to read a call forwarding target phone number that is set, send a call forwarding request to the wireless network, and after a confirmation is obtained from the wireless network, complete the setting of call forwarding.

7. The mobile communication terminal of claim 6, further comprising:

a check timer module, being configured to detect current location information of the mobile communication terminal;

a location comparing module, being configured to compare the base station information of the current wireless network with the base station information of the wireless network where the call forwarding is set to determine a change in location of the mobile communication terminal; and

a call forwarding canceling module, being configured to cancel the setting of call forwarding automatically if a change in location of the mobile communication terminal is determined.
