Abstract

A method, an apparatus, and a system for controlling storage of user input information are disclosed. The method includes: obtaining Dual Tone Multi-Frequency (DTMF) digit mask control information which indicates whether DTMF digit information is suitable for storage; and deciding, when receiving DTMF digit information, whether to store the received DTMF digit information according to the obtained DTMF digit mask control information. In this way, the DTMF digit mask control information controls whether to store the user input information on the DTMF digit information processing device in the architecture with the service function being separated from the bearing function, thus avoiding information security risks brought by indiscriminate storage of sensitive contents in the user input information.

Claims

1. A method for controlling storage of user input information, comprising:

obtaining Dual Tone Multi-Frequency (DTMF) digit mask control information which indicates whether DTMF digit information is suitable for storage; and

deciding, when receiving DTMF digit information, whether to store the received DTMF digit information according to the obtained DTMF digit mask control information.

2. The method according to claim 1, wherein the obtaining of the DTMF digit mask control information comprises:

receiving the DTMF digit mask control information delivered by a controlling device;

or

obtaining preset DTMF digit mask control information locally.

3. The method according to claim 1, wherein:

the DTMF digit mask control information is expressed by a parameter of a signal capable of indicating collection of the DTMF digit information.

4. The method according to claim 2, wherein:

the DTMF digit mask control information is expressed by a parameter of a signal capable of indicating collection of the DTMF digit information.

5. The method according to claim 3, wherein:

the parameter is a Boolean value, and two opposite values of the parameter indicate whether to store the DTMF digit information or not respectively.

6. The method according to claim 4, wherein:

one of the two opposite values is preset as a default value of the parameter.

7. The method according to claim 1, wherein the deciding of whether to store the received DTMF digit information according to the obtained DTMF digit mask control information comprises:

storing the received DTMF digit information if the DTMF digit mask control information indicates that the DTMF digit information is suitable for storage.

8. A Dual Tone Multi-Frequency (DTMF) digit information processing device, comprising:

an obtaining unit, configured to obtain DTMF digit mask control information which indicates whether DTMF digit information is suitable for storage;

a receiving unit, configured to receive DTMF digit information; and

a storing unit, configured to store the DTMF digit information received by the receiving unit if the DTMF digit mask control information obtained by the obtaining unit indicates that the DTMF digit information is suitable for storage.

9. The DTMF digit information processing device according to claim 8, wherein:

the receiving unit is further configured to receive the DTMF digit mask control information delivered by a controlling device, or obtain preset DTMF digit mask control information locally.

10. The DTMF digit information processing device according to claim 8, wherein:

the DTMF digit information processing device includes a Media Gateway (MG), or a media resource processing device, or a media delivery function device.

11. A controlling device, comprising:

a delivering unit, configured to deliver Dual Tone Multi-Frequency (DTMF) digit mask control information to a DTMF digit information processing device, wherein the DTMF digit mask control information indicates whether DTMF digit information is suitable for storage, wherein when the DTMF digit information processing device receives DTMF digit information, decides whether to store the received DTMF digit information according to the DTMF digit mask control information.

12. The controlling device according to claim 11, wherein:

the controlling device includes a Media Gateway Controller (MGC), or a media resource control device, or a media control function device.

13. A system for controlling storage of user input information, comprising:

a controlling device, configured to deliver Dual Tone Multi-Frequency (DTMF) digit mask control information to a DTMF digit information processing device, wherein the DTMF digit mask control information indicates whether DTMF digit information is suitable for storage; and

the DTMF digit information processing device, configured to obtain the DTMF digit mask control information, receive DTMF digit information, and decide whether to store the received DTMF digit information according to the obtained DTMF digit mask control information after receiving the DTMF digit information.
