Abstract

A method for transferring files and apparatus through Wi-Fi Direct are provided. The method includes: an obtaining step, for obtaining a multimedia attribute of a file to be transferred; a sending step, for sending the multimedia attribute obtained in the obtaining step; a receiving step, for receiving information of the multimedia attribute of the file to be transferred; and a judgment step, for judging, according to the information of the multimedia attribute received in the receiving step, whether a receiving end supports the type of the file to be transferred. The embodiment of the patent document solves the problem that the receiving end may know whether to support the type of the file only after completely receiving the file or performing an opening operation, thus leading to inconvenient use, which improves the user experience.

Claims

1. A method for sending files through Wireless Fidelity (Wi-Fi) Direct, comprising:

obtaining, by a transmitting end, a multimedia attribute of a file to be transferred after the file to be transferred is determined to be transferred to a receiving end; and

sending, by the transmitting end, the obtained multimedia attribute before sending the file to be transferred to the receiving end,

wherein the multimedia attribute indicates the receiving end to judge whether to support the file to be transferred,

wherein if the multimedia attribute of the file to be transferred is in a supporting capability list supported by the receiving end, it is indicated that the type of the file to be transferred is supported by the receiving end;

if the multimedia attribute of the file to be transferred is not in the supporting capability list supported by the receiving end, it is indicated that, the type of the file to be transferred is not supported by the receiving end;

wherein the multimedia attribute of the file;

includes content that describes the type of file being transferred and at least one or more operational requirements for processing the file on the receiving end;

is carried in a signaling or message exchange between the transmitting end and the receiving end, and the multimedia attribute of the file is taken as a plurality of fields and appended in any existing protocol data unit (PDU) used for exchange; and

is transferred by the message exchange between the transmitting end and the receiving end;

wherein the supporting capability list describes one or more types of files supported by the receiving end and at least one or more operational capabilities required for processing the file on the receiving end.

2. The method for sending files according to claim 1, wherein the step of sending, by the transmitting end, the obtained multimedia attribute comprises:

encapsulating the multimedia attribute into an independent data packet and sending the data packet by the transmitting end.

3. The method for sending files according to claim 1, wherein the step of sending the obtained multimedia attribute comprises:

carrying, by the transmitting end, the multimedia attribute of the file to be transferred in exchanged data, and transferring the multimedia attribute when the transmitting end and the receiving end perform exchanging.

4. A method for receiving files through Wireless Fidelity (Wi-Fi) Direct, comprising:

receiving, by a receiving end, information carrying a multimedia attribute of a file to be transferred after the file to be transferred is determined to be transferred by the transferring end; and

judging, by the receiving end, whether the receiving end supports the type of the file to be transferred through the received information carrying the multimedia attribute before receiving the file to be transferred from the transmitting end;

wherein the step of judging, by the receiving end, whether the receiving end supports the type of the file to be transferred through the received information carrying the multimedia attribute comprises;

checking a multimedia supporting capability list supported by the receiving end;

if the multimedia attribute of the file to be transferred is in the list indicating that the receiving end supports the type of the file to be transferred;

if the multimedia attribute of the file to be transferred is not in the list indicating that the receiving end does not support the type of the file to be transferred;

wherein the multimedia attribute of the file;

includes content that describes the type of file being transferred and at least one or more operational requirements for processing the file on the receiving end;

is carried in a signaling or message exchange between the transmitting end and the receiving end and the multimedia attribute of the file is taken as a plurality of fields and appended in any existing protocol data unit (PDU) used for exchange; and

is transferred by the message exchange between the transmitting end and the receiving end;

wherein the multimedia supporting capability list describes one or more types of files supported by the receiving end and at least one or more operational capabilities required for processing the file on the receiving end.

5. A computerized apparatus for sending files through Wireless Fidelity (Wi-Fi) Direct, comprising:

an obtaining module, which is configured to;

obtain a multimedia attribute of a file to be transferred after the file to be transferred is determined to be transferred from a transferring end to a receiving end; and

a transmitting module, which is connected to the obtaining module and is configured to;

send the multimedia attribute obtained by the obtaining module to the receiving end before sending the file to be transferred to the receiving end,

wherein the multimedia attribute indicates the receiving end to judge whether to support the file to be transferred,

wherein if the multimedia attribute of the file to be transferred is in a supporting capability list supported by the receiving end, it is indicated that the type of the file to be transferred is supported by the receiving end;

if the multimedia attribute of the file to be transferred is not in the supporting capability list supported by the receiving end, it is indicated that the type of the file to be transferred is not supported by the receiving end;

wherein the multimedia attribute of the file includes content that describes the type of file being transferred and at least one or more operational requirements for processing the file on the receiving end;

wherein the supporting capability list describes one or more types of files supported by the receiving end and at least one of more operational capabilities required for processing the file on the receiving end;

wherein the transmitting module is further configured;

to carry the multimedia attribute of the file in a signaling or message exchange between the transmitting end and the receiving end, and take the multimedia attribute of the file as a plurality of fields and appended in any existing protocol data unit (PDU) used for exchange; and

to transfer the multimedia attribute by the message exchange between the transmitting end and the receiving end.

6. A computerized apparatus for receiving files through Wireless Fidelity (Wi-Fi) Direct, comprising:

a receiving module, which is configured to;

receive information carrying a multimedia attribute of a file to be transferred after the file to be transferred is determined to be transferred by a transmitting end; and

a judgment module, which is connected to the receiving module and is configured to;

judge whether the apparatus for receiving files supports the type of the file to be transferred through the information carrying the multimedia attribute received by the receiving module before receiving the file to be transferred from the transmitting end,

wherein the multimedia attribute comprises;

information sent by the transmitting end to the receiving end for the judgment module to judge whether to support the file to be transferred, wherein the multimedia attribute of the file includes content that describes the type of file being transferred and at least one or more operational requirements for processing the file;

wherein the judgment module is further configured to;

check a multimedia supporting capability list supported by the apparatus, wherein the multimedia supporting capability list describes one or more types of files supported by the apparatus and at least one of more operational capabilities required for processing the file;

if the multimedia attribute of the file to be transferred is in the list, indicate that the apparatus supports the type of the file to be transferred;
