Abstract

A call forwarding method, a terminal, and a portable electronic device, where the method includes determining whether the phone number is in a preset blacklist when a terminal receives a call carrying a phone number, and executing, by the terminal, a preset first call forwarding policy when the blacklist includes the phone number, where the first call forwarding policy includes that the terminal blocks or terminates the call, and does not trigger a server to forward the call to another terminal preset, or executing, by the terminal, a preset second call forwarding policy when the blacklist does not include the phone number, where the terminal presets a call forwarding on busy service or an unconditional call forwarding service.

First claim

What is claimed is:

1. A call forwarding method, comprising:
determining, by a terminal, whether a phone number is in a preset blacklist when the terminal receives a call carrying the phone number; and
executing, by the terminal when the preset blacklist comprises the phone number and a call forwarding on busy service is enabled, a first preset call forwarding policy comprising:
sending, by the terminal to a server, an instruction to disable a call forwarding on busy service;
subsequent to sending the instruction to disable the call forwarding on busy service, sending, by the terminal to the server, a hang-up instruction to terminate the call; and
subsequent to sending the hang-up instruction, sending, by the terminal to the server, an instruction to enable the call forwarding on busy service.

2. The call forwarding method of claim 1 , wherein the instruction to disable the call forwarding on busy service comprises a first unstructured supplementary service data (USSD) instruction, and the instruction to enable the call forwarding on busy service comprises the first USSD instruction.

3. The call forwarding method of claim 2 , further comprising:
receiving, through a user interface, a second USSD instruction to implement an unconditional call forwarding service corresponding to unconditionally forwarding calls;
in response to receiving the second USSD instruction, disabling the unconditional call forwarding service for the call prior to receiving the call by sending the server a third USSD instruction corresponding to a call forwarding on no answer service; and
executing, by the terminal when the preset blacklist comprises the phone number and the call forwarding on no answer service is enabled, a second preset call forwarding policy comprising sending, by the terminal to the server, the hang-up instruction to terminate the call.

4. The call forwarding method of claim 1 , further comprising:
receiving, through a user interface, an instruction to implement an unconditional call forwarding service corresponding to unconditionally forwarding calls;
in response to receiving the instruction to implement the unconditional call forwarding service, disabling the unconditional call forwarding service for the call prior to receiving the call by sending the server an instruction to implement a call forwarding on no answer service; and
executing, by the terminal when the preset blacklist comprises the phone number and the call forwarding on no answer service is enabled, a second preset call forwarding policy comprising sending, by the terminal to the server, the hang-up instruction to terminate the call.

5. A terminal device, comprising:
a display comprising a touch-sensitive surface and a display screen;
a processor coupled to the display; and
a memory coupled to the processor and configured to store instructions that, when executed by the processor, cause the processor to:
determine whether a phone number is in a preset blacklist when a call carrying the phone number is received at the terminal device; and
when the preset blacklist comprises the phone number, execute a preset call forwarding policy comprising preventing a server from forwarding the call to a preset another device by sending the server one or more instructions including a hang-up instruction to cause the server to terminate the call, wherein when the preset call forwarding policy is a call forwarding on busy service, the one or more instructions sent to the server further include an instruction to disable a call forwarding on busy service, and wherein the instructions further cause the processor to send the instruction to disable the call forwarding service before sending the hang-up instruction.

6. The terminal device of claim 5 , wherein the instructions further cause the processor to:
receive, through a user interface, user selection of an unconditional call forwarding service as the preset call forwarding policy; and
disable the unconditional call forwarding service for the call by sending, in response to the user selection of the unconditional call forwarding service as the preset call forwarding policy, an instruction to enable a target call forwarding service to send the hang-up instruction to the server when the preset blacklist comprises the phone number.

7. A non-transitory computer readable storage medium configured to store one or more programs comprising instructions that, when executed by a processor, cause a terminal device to be configured to:
determine whether a phone number is in a preset blacklist when a call carrying the phone number is received; and
when the preset blacklist comprises the phone number, execute a preset call forwarding policy comprising preventing a server from forwarding the call to a preset another device by sending the server one or more instructions including a hang-up instruction to cause the server to terminate the call, wherein when the preset call forwarding policy is a call forwarding on busy service, the one or more instructions sent to the server further include an instruction to disable a call forwarding on busy service, and wherein the instructions further cause the processor to send the instruction to disable the call forwarding service before sending the hang-up instruction.

8. The non-transitory computer readable storage medium of claim 7 , wherein the instructions further cause the terminal device to be configured to:
receive, through a user interface, user selection of an unconditional call forwarding service as the preset call forwarding policy; and
disable the unconditional call forwarding service for the call by sending, in response to the user selection of the unconditional call forwarding service as the preset call forwarding policy, an instruction operable to enable a target call forwarding service to send the hang-up instruction to the server when the preset blacklist comprises the phone number.
